Background of invention

The present invention relates to a device that uses the centralizer of the drill steel, moving on the chassis beam drilling machine, and contains the feed cylinder to move the drilling machine in the direction of drilling and back, at least one rotatable wheel mounted stationary relative to the feed cylinder, and an elastic element supply, moving around him and connected with a drilling machine and a walking beam, the centralizer of the drill steel, mounted for movement on the chassis beam and stationary relative to the cylinder feed in the longitudinal direction of the chassis beams and containing a Central hole for the drill rod, bore a hole on the side of the Central holes to move the drill rod in the center hole and out of it, and means for closing the bore hole during drilling, and the channels for the fluid under pressure for supplying fluid under pressure to the chamber for fluid under pressure cylinder feed from them.

When using a long drill rods and especially when drilling long wells centralizer moving on the chassis beam, normally used to maintain the drill rods, and the centralizer is located between the drill machine and guiding of the drill article is whether on the front end of the chassis beams and moves by chassis beam while moving the drill machine. To create a feed movement and reverse movement of the drill machine is used very frequently the feed cylinder, which is connected to move a wire or chain, connected to the carriage drilling machines. Changing the length of the feed cylinder creates a movement of the drilling machine. In known constructions the longitudinal displacement of the chassis beams provides twice the movement of the drilling machine with the same ratio of speeds. Typically, the centralizer is connected to move with a moving part of the feed cylinder, i.e. pipe or cylinder piston, depending on the solution. Usually the piston rod of cylinder supply is at its end, the United motionless relative to the chassis beams, and the nozzle of the cylinder moves to create a feed movement.

Mainly used centralizer, which contains the hole in the location in which the drill rod is fed to the drill machine. The problem with this solution is that sometimes the drill rod is moved from the centralizer, which means that drilling should be stopped, and the drill rod must be screwed wrench back to the centralizer.

A brief description of the present invention

The aim of the present invention is to provide a device in which the hole centrate is and can be automatically closed and accordingly be opened during use of the drilling machine is easy and simple.

The device of the present invention differs in that the centralizer contains an actuator driven by a fluid medium under pressure for closing the bore hole, a channel for the fluid under pressure is connected between the chamber of the feed cylinder, which is supplied fluid under pressure while drilling to move the drilling machine in the direction of drilling, and the Executive mechanism of the centralizer so that the pressure of the fluid under pressure causes the actuator to close the penetration hole.

The basic idea of the present invention is that the centralizer contains an actuator which closes the inlet and outlet drill stem during drilling. Another important idea of the present invention is that the actuator is driven by a fluid medium under pressure, is connected to the chamber for a fluid medium under pressure to the feed cylinder so that when the power feed drilling machine environment under pressure in the chamber for a fluid medium under pressure to the feed cylinder acts on the actuator and causes it to move the closing element to the hole.

The device according to the present invention provides the advantage consisting in the fact that the centralizer may be closed at the time of drilling, that means that the drill rod cannot move. The opening also occurs automatically when the power feed drilling machine, the user does not need to keep track of this.

Brief description of drawings

The present invention is described in more detail with reference to the accompanying drawings, which depict the following:

figure 1 depicts a schematic side view of the chassis beams drilling equipment, are equipped with a drilling machine and a guide;

figa and 2b depict schematic views of open and closed directional drilling equipment in the longitudinal direction of the drill rod;

Detailed description of some embodiments of the present invention

Figure 1 depicts a schematic view partially cut chassis beams 1 drilling equipment, containing in its upper part of the drilling machine 2, mounted for movement in the longitudinal direction of the traveling beam 1. Usually the drilling machine 2 is installed on the carriage 3 mounted for movement in a known manner on the chassis beam 1, but instead of the carriage 3 drill machine 2 may be directly connected to the chassis beam 1 to move in E. the longitudinal direction. In the longitudinal direction of the chassis beams from the drilling machine in the direction of drilling set the drill rod 4, with the end which can be connected drill bit 4a or the second drill rod depending on drilling equipment and drilling mode. In addition, at the other end of the chassis beams 1 is the guide 5 of the drill steel containing hole drill stem. Between the drill guide 5 and the drilling machine 2 is also the centralizer 6 basic operation and construction of which is described below with reference to figa and 2b. The centralizer 6 also contains a hole through which the drill rod 4 during drilling.

Inside the chassis beams 1 are the feed mechanism with the cylinder 7 filing, a rotary wheel 8 and the elastic element 9 filing. The elastic element 9 filing may be a wire, a chain or something else, the corresponding elastic and strong enough in the longitudinal direction of the element. At the ends of the element 9 filing is usually still connected with the chassis beam 1 by using, for example, the bracket 1a, and it is moved around the rotary wheel 8. The elastic element 9 filing is additionally connected to the carriage 3 drilling rigs in the area between the turning wheels 8 or, alternatively, directly from the drilling machine 2. The end of the piston rod 7a of the cylinder 7 filing is known is, in fact, the method is connected with the chassis beam 1 for stationary fixing in the longitudinal direction. When the supply of fluid under pressure to one end of the pipe 7b of the feed cylinder, i.e. in the case shown in the drawing, into the chamber of the cylinder on the side of the drill guide 5, the outlet 7b of the cylinder moves in the direction of the drill guide 5, causing the elastic element 9 submission to navigate around the rotary wheel 8. As a result of this drilling machine is moved in the direction of the drill guide at a speed which is twice the speed of the pipe 7b of the cylinder. Since the centralizer 6 is connected stationary in the longitudinal direction relative to the pipe 7b of the cylinder, the centralizer 6, respectively, is moved at a speed twice slower speed drilling machine, and its position approximately in the middle between the drill machine 2 and the drill guide 5 remains unchanged during the movement of the feed during drilling and during the reverse movement of the drilling machine.

In contrast to the above, the cylinder 7 filing can be connected to the chassis beam 1 in the opposite direction so that the outlet 7b of the cylinder remains stationary in the longitudinal direction relative to the chassis beams, and the piston rod 7a is moved. In this case, the centralizer and the turning of the wheel of course compounds the s to move with the piston rod 7a. Fluid under pressure may then be sent to the actuator 11 through the piston rod 7a and, if necessary, back to him.

Figa and 2b depict schematic views of a variant of implementation of the centralizer 6, when viewed from the axial direction of the drill rod. Figa depicts the centralizer 6 in the open position. The centralizer 6 has a Central hole 6a in which is placed the drill rod during drilling. On the side of the Central hole 6a of the centralizer 6 contains the penetration hole 6b through which can move the drill rod in the transverse direction of the centralizer in the Central hole 6a or from it. The drawing is additionally depicted closing element 6c, which in the example is connected to the centralizer 6 to rotate with the shaft 10. The axle 10 may be a bolt or some other commonly known fastening means around which can rotate closing element 6c. The actuator 11 is driven by a fluid medium under pressure acts between the closing element 6c and frame 6d clamp 6 and the closing element can be rotated to close the opening 6b. Between the closing element 6c and frame 6d clamp is a spring 12, for example, for removal of the closing element 6c from the hole 6b, when the pressure of the fluid under pressure is receiving no effect on the actuator 11. Thus, the closing element is placed at a distance from the hole when not included feed drilling machines. Actuator 11, for example, is known cylinder driven fluid medium under pressure. The end of the piston rod 11a is connected to the closing lever element 6c, for example, and accordingly the nozzle of the cylinder is connected to the centralizer 6. Chamber for fluid under pressure from pipe 11b of the cylinder are connected with suitable pipe or tube with a chamber for fluid under pressure cylinder feed drilling machine in accordance with the scheme described below in relation to figure 3, causing the fluid under pressure acting in the chamber for a fluid medium under pressure to the feed cylinder, pushing the piston and thus also the piston rod 11a of the pipe 11b of the cylinder and causes the closing element 6c to turn in front of the hole 6b.

Fig.2b depicts a schematic view of the centralizer on figa in the position in which the penetration hole 6b of the centralizer 6 closed.

Figure 3 depicts a schematic view of a hydraulic connection that can be used when implementing the device of the present invention. As shown in figure 3, the pump 13 for supplying a fluid medium under pressure, which fluid under pressure is eat passes through the channel 14 in the valve 15 and, then, through the channel 16 into the cylinder 7 filing and in his chamber 7c for the fluid under pressure. Accordingly, from the second chamber 7d for fluid under pressure cylinder 7 of the feed channel 17 is connected to the valve 15 and the valve 15 channel 18 passes to the reservoir 19 for the fluid under pressure. As an example, in this description, the valve 15 is in its inoperative, which means that fluid under pressure is not supplied to the feed cylinder. From the chamber 7c for the fluid pressure cylinder 7 of the feed channel 20 passes to the actuator 11 of the centralizer 6. As an example, in this description of the actuator 11 is an actuator single-acting or essentially switched. When the power feed drilling machine 2, the valve 15 is moved from its non-working state shown in the drawing, to the left so that fluid under pressure from the pump 13 to supply fluid under pressure through the channels 14 and 16 into the chamber 7c of the cylinder 7 filing. As a result, the pipe 7b of the cylinder begins to move in the direction of arrow A, causing its length increases, and generates the above-described movement of the feed drilling machines. Simultaneously, fluid under pressure in the chamber 7c operates through the channel 20 to the actuator 11 of the centralizer 6 and forces the t its piston 11a to push the cylinder, which pushes the closing element 6c to bulkhead hole 6b. Instead of a separate closing element, the piston rod 11a may act as the closing element. Accordingly, when moving the valve 15 to the right in the drawing, fluid under pressure out of the pump 13 for supplying fluid under pressure through the channel 14, valve 15 and the channel 17 into the chamber 7d cylinder supply, resulting in the outlet 7b of the cylinder moves from the guide 5 and moves the drilling machine 2 and the clamp 6 in the same direction. Simultaneously, fluid under pressure out of the chamber 7c of the cylinder through the channel 16, the valve 15 and the channel 18 into the reservoir 19 for the fluid under pressure. Then the pressure ceases to operate the actuator 11 of the clamp 7, and the spring 12, as described above in figa and 2b, assigns closing element 6c from bore holes 6b.

Alternatively, the valve 15 is depicted in such a way that when it is in its operational condition, is shown in figure 3, fluid under pressure can escape from the chamber 7c of the cylinder 7 supply and pump 13 into the chamber 19 for the fluid under pressure. Then the pressure drops and its effect on the actuator 11 is stopped. As a result, the spring returns the actuator to a position in which the penetration hole 6b is opened.

Figure 3 by the dotted line also shows the channel 21, which is necessary in the embodiment of the present invention. This document uses the actuator is double-acting, in which the movement of the closing element in both directions is always under the action of pressure fluid medium under pressure. Thus, in this embodiment, the channel 21 is connected between the camera 7d cylinder 7 filing, which is supplied fluid under pressure to move the drilling machine 2 in the reverse direction, and the actuator 11 of the centralizer 6, so that the pressure of the fluid under pressure in the chamber 7d cylinder 7 filing during the reverse movement of the drilling machine also acts on the actuating mechanism 11, and causes the actuator 11 to move the closing element 6c from bore holes 6b.

Actuator 11 may be a cylinder driven by a fluid medium under pressure, single-action or double-action, or other Executive mechanism single or double action, such as a motor driven fluid medium under pressure.

In the above description and in the drawings, the present invention is described only as an option and it is not limited to this the m option. The closing element of the centralizer may be connected to move in a different manner for rotational motion or linear motion. In addition, the actuator can, as described, to be a one-time action, so that its reverse movement is effected by a spring or the like and the closing element by means of a flow of fluid under pressure into it. Alternatively, the actuator can be made as the actuator double acting, so that the influence of fluid under pressure to one chamber of the feed cylinder causes a closing movement, respectively, in the other chamber of the cylinder opening movement. The cylinder supply described above so that the nozzle of the cylinder or the piston rod is connected with the rear end of the chassis beams, i.e. stationary with the front end of the drill machine, resulting in movement of the feed piston is ejected from the nozzle of the cylinder, and the total length of the cylinder of the feed increases. Submission can also be performed in such a way that the nozzle of the cylinder or the piston rod still connected with the front end of the chassis beams, i.e. end end drill drill. During the feed movement of the piston then moves in the nozzle cylinder and the total length of the feed cylinder is reduced. Chamber of the cylinder and connections IU the control actuator and the chamber of the cylinder is then naturally selected in accordance with the present invention.
