The invention relates to a device intended to change the drill element in the installation of drilling rock soil containing a vehicle and a beam mounted movably with respect to it, which is movably attached to the drill site that contains, at least, drill hammer, feed rod and the feed means, and the device contains at least one store for storing drill elements used in the drilling process, and the power change drill elements, providing their transport between store to store drill elements and drill site.

Extremely high stresses occur in the drill bit used for drilling rock soil, so the bit must be changed due to wear and possible damage. For efficient drilling of rock soil drill bit should be in good condition. In the known solution at the drill site, install the device change the drill bit, including the store. However, this solution has the disadvantage that the weight and dimensions of b who I viewed as unsatisfactory. For heavy constructions require a powerful beam and heavy tool to move the drill site, and it also increases the cost of manufacture of the equipment. Also, maintenance and commissioning of equipment difficult, when you shop for the drill bit and the block change is placed close to the feed rod. In addition, removing a used drill bits and store new bit difficult. In addition, not all cases have the capability of providing a drill site, drilling bits in sufficient quantities, because the weight and dimensions of the store limit the number of drill bits. We developed the equipment, allowing to solve the above problems, in which the drill bits in advance is fixed at the ends of the drill rods, and then they are placed in the store for storage of drill bits on the vehicle. In such embodiments, the problem lies in the fact that the device for manipulating the rod requires a certain degree of freedom in order to be able to move the drill rod with drill bit from the store to the drilling site. In this case, should be provided with the ability to manage complex movements, which use expensive ito, because drilling bit attached to drill rods, to manipulate them is difficult because of their large size and weight. This store occupies a lot of space.

Thus, the prior art a device for changing the drilling element in the installation of drilling rock soil containing vehicle, a beam mounted movably with respect to it, which is movably attached to the drill site that contains, at least, drill hammer, the input beam and the input means, and the device contains at least one store to place the drill elements used in the drilling process, and the power change drill elements, providing their transport between the store and the drill site (see, for example, the book Ivanov, K. I., Latyshev Century A. and others, the Technique of drilling in the development of mineral resources, Moscow, Nedra, 1987, S. 124, rice.4.4, 4.5).

However, if you shop for the drilling elements installed in connection with drill site, as in the case described in the book Ivanov, weight and other parameters of the drill site to be very significant. As a result of this work with such a drill site can be complex and the appearance of the object and drilling may be bad. Over the m node.

The technical task of the present invention is to provide a novel apparatus for changing the drill bit or other drilling element of the drill site with a simple design, excluding the regulation of complex movements of the replacement unit drill elements and do not add weight and do not increase the dimensions of the drill site.

This technical problem is solved by a device for changing the drilling element in the installation of drilling rock soil containing vehicle, a beam mounted movably with respect to it, which is movably attached to the drill site that contains, at least, drill hammer, feed rod and the feed means, and the device contains at least one store for storing drill elements used in the drilling process, and the power change drill elements, providing their transport between store to store drill elements and drill site, which according to the invention store for storage of drill elements installed on the vehicle or on a beam separately from the drill site, and the device comprises means for moving the drill usly drill element.

The power change drill elements can be installed on the vehicle or on the beam.

In addition, the power change drill elements can be installed with the possibility of rotation about its hinge between store to store drill elements and drill site and contain the lever is made with the possibility of lengthening or shortening, and at the free end of the lever is located clamping device for gripping the drill elements.

Preferably store for storage of drill elements and the power change drill elements are installed on the beam, resulting in a relative position of the store for items that block change elements and drill site is independent from the position of the beam.

Also preferably, the power change drill elements installed with limited movement in accordance with the relative location of the predetermined position of the shift of the drill site and store to store drill elements.

Preferably the power change drill elements placed on the drill site and made with the possibility of transfer of drill elements between store to store drill elements and the position of the holding at the end of the EIT building, on the periphery of which is placed the pins or lugs for attachment of the drill elements.

Preferably the beam has two rods along the installation drilling rock soil at a distance from each other, and a store for storing drill elements, and the power change drill elements placed between the bars of the beam.

The advantage of this invention is that changing the drill bit does not require complex movements of the unit shift elements, so this unit can have a simple and reliable design. This allows you to reduce the cost of manufacture and operation of the unit shift. In this case, does not require complicated and unreliable sensor or control devices with precise control of movements. The rate of simple movements can significantly increase, which will significantly reduce cost and time to change the drill bit. This solution provides the further advantage that, when the power change items and store items installed on the vehicle or on a beam, they do not add weight and do not increase the dimensions of the drill site, thereby facilitating the manipulation of equipment, providing the best view of the drilling and the placement of store items on the beam or on the vehicle allows you to store larger sizes or more stores that ensures continuous operation of the drill head.

Hereinafter the invention will be described in detail with reference to the accompanying drawings, in which

Fig.1 and 2 schematically represent installation drilling rock soil, which are introduced changer drill element according to the present invention;

Fig.3 and 4 schematically represent the principle of installation of electric pipe used for drilling rock soil.

In Fig.1 is a schematic representation of part of an installation, drilling rock soil, in which you can enter the device according to the present invention. It should be noted that in this application, the term “drill element” refers not only to drilling bits, but also, for example, to electric drill pipes, described later with reference to Fig.3 and 4, and in the drawings also presents a means for the installation of these pipes, and other items that are required during drilling and the manipulation unit change drill elements. Installation drilling rock soil, shown in the drawings, includes maneuvering the vehicle 1 cabin 2 control, as well as the necessary additional devices. Beam 4, which can be raised and lowered using hydrotrend rod, passing along the vehicle 1 at a distance from each other, and they can be left on the ground during the drilling process and, accordingly, to raise at least during handling equipment for drilling rock soil. For clarification of the drawing shows only the rear bar of the beam, and the cross-sectional shape transverse rod 4A, which connects the rod. The actual drill site 5, containing at least drill hammer 7, the feed rod 6, as well as other means of filing, installed on the beam 4, mainly at its free end. In the drawing, the drill site is partially shown by the dashed line. Drill hammer 7 is moved under the action of hydraulic cylinders, for example, along the feed rod 6. Drill site 5 can move in different ways relative to the beam 4. First, the entire drill site can be rotated with the help of a hydraulic motor, for example, in the direction “A” with respect to the first horizontal axis 8. Further, it can be raised and lowered in the direction “B” by means of a lifting device 9 of the drill site, such as a hydraulic cylinder. Drill site can also be tilted forward and backward relative to the beam 4 in the direction “C” as pocataligo hammer with the other tilting cylinders, not shown in the drawing. Using the navigation above the drill site can be sent is specified by, due to which it can be used for drilling many holes, for example, in the ceiling, walls or floor of the tunnel. Specified position of the drill site, you can hold by pressing separate supports to the surface during drilling. In addition, the equipment for installation of anchor supports on rocky ground or loading equipment can be mounted on the feed rod, which can be moved in the drilled hole in the step mode, for example, as soon as the drill bit with the drill rod is moved in the lateral direction. For drilling using the extensible rods for them to set the store 11 for storage of drill elements, mainly on the drill site, and the rod can be connected in series between a corresponding automatic means or rod can be disconnected from the system of drilling rods and known way to stack for storage.

When drilling with increasing weights blunt drill bit usually replace before drilling a new well, as in any SL, Arashiyama rod disassemble and drill the node is moved to the position change. After replacing the drill bit drilling unfinished well in most cases you can continue, then drill site translated using system automation control beam to the hole of the well.

Change the drill bit according to the invention in this case is thus that the store 12 is placed on the beam, and is intended for drill bits to be replaced, and this store can preferably be rotated in the direction “E”, and in this store to store drill bits or any other necessary items can be stored in an easy way. If necessary, you can use other types of stores, such as a chain. The store shown in the drawing, in the simplest embodiment, may be made in the form of enclosure 13 disk-like shape on the peripheral part of which has pins or lugs 14, which can be worn elements 15, which is made of the inner hole. In this way it is easy to capture the outer peripheral part of the elements of the fixture block shift elements or any other similar managing device. Shop 12 advantages of the pile, it does not hinder the view and does not increase the overall dimensions of the device of the rock drilling soil. Because the store 12 is not placed on a drill site, it may be increased in size so you can fit more items than previously. Further, in accordance with the invention idea unit 16 shifts is installed on the installation of drilling, and block shift elements refers to the type in which the manipulator is able to move the drill elements 15 between elements 12 and the drill site 5. The drill head is moved to a predetermined position to change elements. In modern installations, drilling rock soil is known, the use of automation, such as digital for the direction and control of the beam and drill site automatically in accordance with precise drilling program. Such control can also be used to transfer the drill site in the position to change elements. Because it is precisely known relative location of the store 12 elements and drill site 5 in the position change of the elements and, further, since the drill site that is in this place, anyway is located in a favorable position in relation to the implementation of change within was protosols more than two axes, i.e., enough to have at least two degrees of freedom. The drawing shows a block shift elements containing the lever 17, the hinge connected to rotate with the beam, and the other end thereof can be extended and shortened in the direction F. At the free end of the lever 17 has a clamping device 18, which captures the elements to be transferred over the external peripheral part. Unit 16 shifts the drilling elements can be rotated about a horizontal swivel connection 19 in the direction G by using the hydraulic cylinder 20 or the relevant Executive mechanism.

The drill element is placed so that the drill rod Assembly can be disassembled automatically (bar behind the bar) and send them to the store for storing drill rods.

Rod usually join in a threaded connection that can be released by rotating the drill hammer. If necessary, drill hammer can be used to churning released jammed connections. When the last drill rod with drill bit on the end of the pull produced from the well, the drill site 5 is transferred to a position at which change the drill bit, and at this stage elements. The drill site is mainly transferred in the vertical position, in which the selection of the drilling elements of the store and their placement for connection to the drill site can be performed without changing the position of the clamping device. If the clamping device 18 of the unit 16 shifts the drilling elements are pivoted, the change can also be produced when the drill site move horizontally relative to the vehicle or transform it in a certain angular position. On the position change of the elements of the drilling unit should be mounted at a height of predominantly so that the power change drill elements could change element, advantageously using moving block. Rotational motion block change drill elements are easily limited by mechanical means, for example, when translating it into the specified position in this case does not require regulation of specific movements or execution of control operations. The lower position of the lever 17 unit change drill elements can also limit mechanically relative to the store 12 for storage of drill elements, and in this case, the unit shift elements has the ability to turn on the set the tracks to limit the extreme positions, for example, using stem 17A, since the distance between the unit 16 shifts the drill elements and store 12 for storage of drill elements, and between the block 16 of the shift elements and drill site 5 is known in advance. When the positional displacement of the block is quite simple, as in this case, without having precise control of the movements, design and principle of operation of the unit shift can easily be represented by applying conventional drilling elements that were considered reliable. Further, there is no need to use complex control and measuring equipment. In addition to this, the velocity of the block change drill elements can be large.

Using unit 16 shifts the drilling elements remove drill bit with shank 28 and transfer it to a shop to store the elements from which the unit shift simultaneously captures a new drill bit and transfers it to the drill head. Drilling element is placed using block change drill elements in the direction along the axis “H” move or feed hammer drill 7, with threaded connection of the drill member with the shank of the bit is clamped when screwing the bit on the thread between ale is Eesa means, holding the rod in place after removing the drill bit from the shank. After this drill, the hammer is moved back to its original position, between the bit and shank you can install the extension. To perform continuous drilling can accommodate a variety of extension poles between the drill bit and hammer drill. Also, you can set the power change drill elements so that he could file a drill bit directly to the end of the feed rod to hold that allows you to speed up the operation.

In addition to the solution shown in Fig.1A, it is possible to place the power change drill elements and store to store drill elements on the vehicle, in this case, the location of the block shift and store known regardless of the position of the beam. The power change drill elements can also be installed on the vehicle, and a store for storing drill elements on the beam, or Vice versa. In the latter case, the position of the block change drill elements with respect to the store for storage and data necessary for the control unit shifts can be obtained by using, for example, the respective sensors to the provisions of the strong elements. Depending on the point of fixation unit change drill elements and store to store drill elements moving unit change between the shop and drill the node is managed either through fixed restrictors, or on the basis of the information issued by the respective position sensors.

In Fig.2 presents a solution in which the unit 16 shifts the drilling elements mounted on a drill site 5. Unit 16 shifts the drilling elements can be fixed hinge on a feed rod 6, in this case, it can capture elements 15 from the magazine 12 for storage of drill elements and transfer them directly to the end of the feed rod to secure. Drill element 15, which is designed for fastening on the end of the feed rod, shown by the dashed line. For clarity, not shown actuators, which are used to rotate the unit 16 shifts the drilling elements. This option provides the advantage that, when the drill element 15 is captured for retention, unit 16 shifts the drilling elements can be rotated without any complicated controls, because the relative location of the block change drill elements and the position at which vypolnjaete is retenu translates to known position at a desired location with respect to the store 12 for storage of drill elements for changing the drilling element, the location of the block change drill elements relative to a shop for them on the position shift is also precisely known.

In Fig.3 presents the principle of placing electric drill pipe in the well. The purpose electric drill pipe 21 is to prevent pieces of rocks 22 formed in the drilling process, to wrap up the drilling environment during drilling downward or down a slope, and flow down in a drilled well. Drill electric tube forms a circular mound, located high above the drilled borehole. To install electric drill pipe 21 are drilling the initial hole 23, using a drill bit the diameter of which is larger than the diameter of a given well, and then electric drill pipe is partially pushed into the borehole, as shown in Fig.4. The internal diameter of the electric drill pipe 21 is chosen so that the actual drill bit 24 with elongated rods 25A, 25b, 25C can be pushed through the pipe for the drilling of wells 26 of a given size. Drill electric pipe of this type is usually set manually, which is laborious and inconvenient and does not meet modern requirements for drilling rock soil. This is ametra, designed for drilling holes for electric drill pipe, can be placed in the store for the items and get it from the store, and the appropriate tool to install electric drill pipe can be placed on the shank after drilling holes for electric drill pipe. Then the unit shift elements delivers electric drill pipe that you want to install, and puts it on the tool associated with the shank and the tool has the form of a plunger 27, and after that electric drill pipe 21 is led to the plunger to install and enter it into the opening 23 through the feeder hammer drill. Next, the plunger is removed using block change elements, and the drilling continues in the usual way via electric drill pipe.

You can use not one but several shops to store items, for example, are two: first store for tools, such as drill bits and the plunger for electric drill pipe, and a second store for electric drill pipe. Shops, for example, may be such as shown in Fig.1, they can be placed adjacent to each other side by sides in the volume between the forks of the beam, looking from the front of the drill hammer. In this SLC shift elements can also rotate in the lateral direction of the hammer drill. Lateral movement of the block shift elements can also be restricted in its extreme position. On the other hand, shopping can be arranged in such a way that, if you need to manipulate the elements, then each time the store lead to a certain place where the unit shift elements can manipulate the items in the store. This layout also determines the coordinate at which the drill site is placed in a position to change the elements.

The drawings and their description is provided only to illustrate the merits of the invention. In detail the invention may vary within its formula. Thus, beam hammer drill or drill site does not have to be such one as shown in the drawings, the invention can be applied to installations drilling rocky soils of other types. Further, in contrast to the construction shown in the drawing, the unit shift elements may allow rotation only horizontally, in this case, shop for items can be placed, for example, behind the cab on the vehicle. Replaceable elements and block their change in this case will require the simplest of rotation of the block change only n is altoadige of the invention can successfully be used in other situations, not only with regard to change drill bits, etc. when drilling with extension rods. So the device according to the present invention generally does not need to contain a cartridge with drill rods or it can be placed in any other location, not on a drill site.
