Machine 5 for drilling rock may contain impact device for transmission of shock pulses in the tool 8, which transmits them to the drill bit 10 and later in rock 11 subject to destruction. Machine 5 for drilling rock may also contain a rotating device, which enables the rotation of the tool 8 around its longitudinal axis in the drilling process.

The drilling unit 4 is additionally equipped nakopitel the NYM device 13 for rods, based on the guide 6. Storage device 13 for rods can be used for storing drill rods 9 and other drilling tools for drilling deep wells. Storage device 13 for rods equipped with auxiliary devices to move the drilling tool between the accumulation unit 13 for the rod and the axis of the drill, i.e. the center of K.

In addition to car 5 for drilling rock drilling unit 4 can be equipped with a device for anchoring mounted on the guide 6 indexed image, for example, to allow storage of anchor bolts in the storage device 13 for the rod. With the aim of greater clarity, the figure does not show a device for anchoring in connection with the drilling unit 4.

Advanced setting 1 for drilling rocks can be equipped with one or more arrows pointing devices 15, equipped with a unit 16 for anchoring to be used to install the anchor bolt 17 into the hole 12 drilled in advance. Unit 16 for anchoring device 18 for anchoring, which can be mounted on the rail 16 and the like, the Device 18 may be equipped with an accumulation device 13 for rod storage anchor who's bolts 17 and to capture them in line anchoring, i.e. in the centre K of the device 18 for connection bolts.

Fig. 2 shows the drilling rig 4 with the storage device 13 for the rod for the storage and manipulation of drilling rods 9. The principle warehousing storage device 13 for linear rods, i.e. rods 9 are arranged in one line, parallel to each other, side by side. Fig. 2 shows a performance in which the rods are vertically, one on top of another. Storage device 13 for the rod contains two feed element 19, which support rod 9. The feed elements 19 are located at a distance from each other and at a distance from the ends of the rod 9, whereby the long rod 9 is also well supported. The feed elements 19 are elongated parts that can be rotated around their longitudinal axis. The feed elements 19 can be equipped with the engine rotation, as for example a hydraulic motor. The feed elements 19 contain helical surface, which provide the ability to move the rod 9 within the storage device 13 for the rod. Additionally, storage device 13 for rods may contain two moving means 21, which may be performed in connection with the feed elements 19. Using moving elements 21 of the rod 9 can be moved from the storage device 13 is La bars in the centre of K and Vice versa. Detailed design and operation of the feeding unit 19 and the detailed design and operation of the shunting element 21 shown in the following figures.

Fig. 2 additionally shows that the storage device 13 for the rod includes an end support 22, which prevent sliding of the rods 9 in the longitudinal direction, when the drilling unit 4 goes up or down. Angle connector 22 may be a lever supported on the guide rail 6, and the most remote from the center section of the lever has a supporting surface on the side of the ends of the rod. Storage device 13 for the rod may further comprise two transverse support 23 mounted on a feed element 19 on the side facing away from him. The transverse support 23 prevents the release rod 9 in the storage device 13 for rods from contact with the helical surface of the feeding element 19 in the transverse direction. The transverse support 23 may rely on the guide 6 and to provide a flat bearing surface against which the rod 9 is easy to move the feed element 19. Storage device 13 for the rod, therefore, contains at least two blocks 24a, 24b manipulation, located at a distance from each other and containing at least the feed element 19, the moving element 21 and the transverse support 23. Blocks 24a, 24b manipulation can be easily equipped with fences around them to prevent damage. In General, the storage device 13 for the rod of the invention can be quite easy and simple design. In some cases, a storage device for rods can contain only one unit of manipulation.

Fig. 3 shows a block 24b manipulation belonging to the storage device 13 for the rod. Vertical storage device 13 for the rod holds four rods 9 stored linearly, one on top of another. Naturally, the parameters of the storage device 13 for the rod can be adjusted for smaller or larger number of rods. The rod 9 is moved in a linear direction feeding element 19, containing a helical surface 25. In the variant shown in figure 3, the screw surface 25 is a coil 26, which is supported by the elongated body 27 of the feeding unit 19, and the housing can be rotated around its longitudinal axis so that the screw surface 25 opposite to the bottom surfaces of the rods 9 raises or lowers the rod depending on the direction of rotation of the feeding unit 19. No separate intermediate details are not needed between superimposed on each other by rods 9 to create a gap 28 between the rods 9, because SPIRA is 26 is located between the rods 9 and inevitably forms a gap 28 between them, as shown in figure 4. The body 27 of the feeding unit 19 can be rotated by rotation of the motor 29. Instead of the spiral 26 feed element 19 may include an elongated screw, which rotates around its longitudinal axis. This option does not require a separate housing 27. The parameters of the steps of the thread of the screw and the spiral 26 may be chosen so that the rod to be moved are tightly fixed in the space between the coils or spirals. In addition, the parameters of the helical surface 25 and the rest of the design of the feeding element must be selected in such a way as to ensure the possibility of receiving the weight of the rods 9 in the storage device 13 for the rod. This aspect should also be taken into account when selecting options in the tool rotation.

Fig. 3 and 4 show that the feed element 19 can be rotated in a predetermined angle B relative to the rod 9. The tilt in the plane parallel to the longitudinal direction of the rods 9. The upper ends of the conveying elements 19 blocks 24a and 24b manipulation can be inclined to each other. The angle B of inclination can be selected according to step screw surface 25 so that the bottom surface of the rods 9 relied on linear opposing surface of the spiral 26 or flat opposing surface of the screw thread. Feed al the COP 19 can be mounted with a fixed angle of inclination or the alternate angle B of inclination can be adjusted manually or using a suitable actuator. The parameters of the thread pitch of the helix 26 of the feeding unit 19 or alternative step screw threads can be selected according to the rod 9, having the largest cross-section. However, the storage device 13 for the rod, equipped with a data type of the feeding unit 19, can also be used to manipulate the rod 9 of a smaller diameter. If in this case it is necessary to prevent the formation of gaps between the rods 9 of smaller diameter and the feed element 19 and the resulting swinging rods 9, the feed element 19 can be rotated in the direction B, which provides the possibility of reducing the gaps. It is also possible that the part with the screw surface 25 of the feeding unit 19, was a replacement part that can be easily replaced in accordance with the rod 9, to be moving at a certain time.

Fig. 3 and 4 show that the feed element 19 may be equipped with a sensor 30 for tracking the rotation of the feeding unit 19. The measurement result obtained from the sensor 30 may be transmitted to the control unit 40 for controlling the operation of storage device 13 for the rod. The parameters of the thread pitch of the feed element 19 can be selected, for example, so that one full rotation around the longitudinal axis causes movement of the rod 9 up or down one position in nakopitel the nom device 13 for the rod. Of course, there is also another tool accessories selection of sizes and management strategies, because the control unit 40 can calculate the required rotation of the feeding unit 19 based on the thread pitch of the helical surface 25 and the required distance of movement.

Fig. 3 and 4 show the moving element 21 that contains a lever 31 having essentially the shape of the letter C and is attached to the guide rail 6 by means of hinge 32. Transferring element 21 can be rotated rotating element 33 in the direction C, across the guide 6. Most remote from the center portion of the moving element 21 can be equipped with a gripping tool 34, such as grippers 37, for gripping rods 9. An exciting tool 34 may be used in the direction D exciting actuator 35. Rotating device 33 and exciting the actuator 35 may be a hydraulic cylinder, only schematically shown in Fig. 3 and 4. Alternatively can be used other actuators that are suitable for this purpose.

In Fig. 5 moving element 21 has been rotated to its original position, and the outermost end of the arm 31 is located on a feed element 19. Most remote from the center of the end of the lever 31 can be equipped with protivodeystvuyushee item 36, when this input element 19 can move most remote from the center of the rod 9a storage device 13 for the rod in the direction of him to rely on it. In its most simple form opposing part 36 may be a part having a shape corresponding to the outer surface of the rod, as shown in the figure. Opposing part 36 may also contain the period or feed installation 39, equipped with a lock, or similar locking mechanism, and which may include the most remote from the center of the rod 9a supplied from the storage device 13 for the rod. It is also possible that the upper part of the feed element 19 was equipped with means for receiving the most remote from the center of the rod 9a and holding it up until the moving element 21 will not receive the rod to move. Additionally, an exciting means 34 on the most remote from the center of the end of the lever 31 can contain one or more able to be open or able to close the grippers 37, which are breathtaking actuator 35. The hooks 37 of the shunting element 21 can hold the most remote from the center of the rod 9a in the storage device 13 to the rod opposite the opposing parts 36. Following this, the lever 31 can poweraqua the in the direction C to move the rod 9a in-line drilling, i.e. the centre of K. This situation is shown in figure 6. As it can be seen, the C-shape of the arms allows them to rotate in the transverse direction without collision levers with other rods 9 in the storage device 13 for the rod. Since the levers 31 are located next to the feed element 19, the lever 31 does not collide with the feed element 19 when turning. When the rod 9a delivered in the centre of K, the hooks 37 can be opened and the lever 31 may be returned to its original position, shown in Fig. 5, to allow the introduction of the next rod. In this regard, the detailed manipulation of the rods in the center, such as the opening and attaching the connecting links, are not described.

When a borehole is drilled, and equipment for increasing drilling rods is removed, the lever 31 is directed into the centre of K, whereby opposing item 36 set opposite the rod 9a in the center, after which the gripper 37 is closed and the lever 31 is turned to its original position on a feed element 19. Following this, the gripper 37 is opened, and the rod 9a is moved to the supporting screw surface 25 of the feeding unit 19. The feed element 19 rotates so that the rod 9a inserted into the storage device 13 for the rod moves down one position, whereby the location in the input is a set S is released to the rod, to be inserted after this. This continues until all rods will not be unloaded or until the storage device 13 for the rod is filled bars.

Fig. 7 and 8 show a variant of the storage device 13 for the rod, in which the feed element 19 and the transverse support 23 is made to rotate in the direction C together with the lever 31. In this case, turn all of the rods 9 in the storage device 13 for rods and there is no need to give the lever a shape of the letter C, as in the previous figures, because he can no longer collide with the rods. Therefore, the design of the storage device 13 for rods may be narrower than the design shown in Fig. 5 and 6. Storage device 13 for bars made with the possibility of rotation about hinge 32 as a whole, thus providing the possibility for supply unit S in the upper part of the feed element 19 in the center of K, as shown in Fig. In other respects the characteristics of the embodiments shown in Fig. 3-6, for example, with regard to the feeding unit 19, can be used in variants of the implementation of Fig. 7 and 8.

In the embodiment shown in Fig. 7 and 8, the storage device 13 for rods may not contain any of the levers 31, but as moving items the NTA operates rotatable feed element 19. In this case, the feed S in the upper part of the feed element 19 can be equipped with the necessary breathtaking vehicle.

Fig. 9 and 10 show the storage device 13 for rods that can be moved by means of the coupling device 39. Fig. 9 shows the initial position, and Fig. 10 the situation in which the feed S was delivered to the center K. the Connecting device 39 may be composed of at least two levers 40a and 40b, which are made with the possibility of rotation by means of hinges 41a and 41b to the feed mechanism 19, and on the other hand, rely on the guide rail 6 by means of hinges 42a and 42b. The connecting device 39 is located so that the storage device 13 for the rod was turned in the direction C changing along a curved trajectory. The parameters of the levers and the mutual position of the hinges can be used to influence the shape of the curved trajectory. The curvature of the trajectory is changed so that its radius becomes smaller towards the center K. the Advantage of this is that the storage device 13 for the rod does not increase the size of the drilling rig upwards. Of course, for the movement of the storage device 13 for rods, you can use other coupling devices, p is Rhodesia for this purpose.

Additionally, the feed element 19 shown in Fig. 9 and 10, is a coil 26, the parameters of which can be chosen so that it is capable of carrying the weight of the rods 9, not based on any building in the middle of the spiral, as shown in Fig. 3-8. Inside the spiral 26 or alternative outside it may be is not able to rotate the transverse bearing 23b, which together with the transverse support 23a stores the rod 9 in a linear arrangement and prevents the output rod 9 from contact with the helix 26. Opposing part 36 and an exciting means, if they occur, can be mounted on the free end of the transverse support 23b. Transverse supports 23a and 23b can be replaced with a pipe, made without the possibility of rotation, mounted around the feed element 19 and having a groove that opens in the supply S and the groove is parallel to the rods 9 in the storage device, to allow movement of the rods in the storage device. Of course, also possible transverse support any other design.

It is also possible to storage device 13 for the rod did not have any separate gripping means, but the feed element 19 and the opposing part 36 could be made with the possibility of a joint operation in ka is este variety of exciting links and hold the rod in the input setting S, when the storage device 13 for the rod moves to the center of K. using the feed element 19 rod 9 can be pushed relative to the opposing parts 36 or similar surface. Therefore, a separate exciting parts are not needed, resulting in the design could be even more simple.

Fig. 11 shows the storage device 13 for the rod to its original position under the diagonal angle to the guide 6. The feed element 19 may be a spiral 26, based only on the engine rotation 29. Outside of the spiral 26 can be mounted without the possibility of rotation of the bearing 43, the upper part of which may be equipped with a moving element 21, which may include a lever 44, moving in a linear direction L. the Lever 44 can be moved by a suitable actuator 45, such as a hydraulic cylinder. The lever 44 is equipped with a gripping means 34, which can be moved in the linear direction L between the supply S and the center K.

Fig. 12 and 13 additionally illustrate the solution in which the storage device 13 for the rod can be moved under control by the guide surface 46 from the starting position according Fig in the position shown in Fig, with feed setting S in the center of K. storage device 13 DL the rods can be supported on the guide surfaces 46, for example, the rollers 47. Of course, there are also other treatment options guide surface 46 and reference links based on it. Fig. 13 actually depicts the guide surface, shown by the dashed line, and for delivery supply unit S in the center of the K storage device 13 for the rod can move along the surface in a linear direction L2.

Usually storage device 13 for the rod is located on one side of the guide as shown in the figure. Depending on the settings handedness of the drilling unit or device for connecting bolts storage device for rods can be from the right hand or left hand, if viewed from the side of the boom arm. Both sides of the guide 6 can be equipped with adjusting elements, which provide the ability to easily change settings handedness of the drilling rig. The design of the storage device 13 for rods may be symmetric, in which case it can be attached to each side of the guide 6 without any changes. In some cases, the storage device 13 for rods can be mounted on both sides of the guide 6, whereby the amount of the dumped drilling tools or anchor bolts may be longer. In this case, both n kapitulnik device for rods 13 can be equipped with individual feed elements 19 and moving elements 21. Usage of the storage device 13 for the rod, as shown, for example, in Fig. 7 and 8, is simple for placement on both sides of the guide. Additionally, the moving element 21 of the storage device 13 for the rod of the type shown in Fig. 5 and 6, can be interpreted in contrast to the figures as a single moving element, is arranged to move the rod between the center and the two feed elements. It is also possible that the first side of the guide had storage device for drill rods, and the second side - storage device for anchor bolts.

Instead of a uniform helix 26 or the screw surface of the feeding element 19 may be formed so that it included a large number of screw elements mounted with respect to each other so that together form a screw pitch of the thread, to provide support and/or movement of the rods. Screw elements may represent, for example, spikes, plates or similar protrusions, which are located on the outer surface of the rotatable housing, rotate the engine rotation so that through the support surface could be extended imaginary helix with pitch, designed for installation in front of the rods VI the wall elements.

Instead of a vertical position initial position storage device 13 for the rod may be a diagonal position, as for example, in Fig. 9 and 11, or it can even be a horizontal position.

Despite the fact that Fig. 3 through 13 show signs of storage device 13 for rods and a variety of applications in relation to the drilling unit, the appropriate characteristics, specifications and applications can also be used in conjunction with the device for connection bolts for the storage and manipulation of anchor bolts.

The drilling assembly includes a power aggregate for its power supply, a support frame, which can move between in parallel to the rock and in perpendicular to the rock positions, and the support frame moving device. A rotor block and a carriage aimed to transfer rotation, axial and return towing (lifting) forces to the drill pipe. The drilling assembly aimed for wells drilling with use of the drilling pipe through underground rocks formations, with any angle relatively to the underground rocks, between in parallel to the rock and in perpendicular to the rock positions. The method includes the drilling pipe dislocation on the drilling assembly, the support frame movement in setting it in the required drilling angle, the rotor block and carriage movement till it have contact with the drilling pipe, transfer rotation, axial and return towing (lifting) force to the drill pipe and underground rocks formations drilling with the drilling pipe.

EFFECT: invention provides power increase for the rotation drive and easy transportation.
