Technical Field

[0001] This invention relates to the field of drilling rig guide rail technology, specifically to an automatic guide rail clamping device. Background Technology

[0002] As the primary exploration and drainage equipment in coal mines today, drilling rigs are in high demand. Currently, to meet the needs of cross-belt conveyor operations, ordinary drilling rigs typically have telescopic hydraulic cylinders installed at the bottom of the guide rails. These cylinders can move the guide rails back and forth to compensate for the distance between the guide rails and the coal wall on the conveyor belt side, bringing the guide rails closer to the coal wall. However, the traditional compensation method still has the following problems: When the drilling rig is working, even if the entire guide rail is close to the coal wall to meet the needs of cross-belt operation, its working position is still not stable and fixed, the overall stability of the main unit is reduced, the guide rail is prone to shaking during drilling, and the accident rate is high. Summary of the Invention

[0003] This invention proposes an automatic guide rail clamping device, which solves the problem in related technologies that the position of the guide rail near the coal wall cannot be fixed under the action of the telescopic hydraulic cylinder, resulting in easy shaking during drilling.

[0004] The technical solution of the present invention is as follows: An automatic guide rail clamping device for controlling the guide rail to clamp against the coal wall, comprising: Mounting base; The guide rail is slidably mounted on the mounting base, and the guide rail has a first limiting hole; A clamping member is slidably disposed on the guide rail. The clamping member has a second limiting hole. After sliding, the clamping member abuts against the coal wall, and the first limiting hole communicates with the second limiting hole. A limiting member, which is located simultaneously within the first limiting hole and the second limiting hole.

[0005] As a further technical solution, the clamping member comprises two parts, which are symmetrically arranged on the guide rail, and further includes: A disc abutment is provided on the end of the tightening member away from the mounting base. After the tightening member slides, the disc abutment abuts against the coal wall.

[0006] As a further technical solution, it also includes: A limiting cylinder is disposed on the guide rail and located below the first limiting hole. The tightening member is slidably disposed inside the limiting cylinder. The limiting cylinder has a third limiting hole that communicates with the first limiting hole. The limiting member is simultaneously located inside the first limiting hole, the second limiting hole, and the third limiting hole.

[0007] As a further technical solution, the limiting member is a pin, and there are several second limiting holes. The several second limiting holes are arranged at intervals along the sliding direction of the tightening member. After the tightening member slides, the first limiting hole connects or disconnects from the second limiting hole.

[0008] As a further technical solution, the sliding direction of the guide rail is parallel to the sliding direction of the clamping member, and the clamping member moves closer to or further away from the mounting base after sliding. The solution also includes: A driving component having a driving end is disposed at the bottom of the mounting base, and the guide rail is connected to the driving end.

[0009] As a further technical solution, the clamping member includes: A support cylinder is slidably disposed within the limiting cylinder. The support cylinder has a strip-shaped hole and a disc portion, and the limiting member passes through the strip-shaped hole. The drill rod is rotatably disposed inside the support cylinder. The rotational axis of the drill rod and the sliding direction of the support cylinder are both parallel to the sliding direction of the guide rail. The drill rod has a second limiting hole. After the support cylinder slides, the disc portion abuts against the coal wall, and the drill rod drills into the coal wall.

[0010] As a further technical solution, the drill rod also has a groove, the groove being axially collinear with the drill rod axis, and further includes: A threaded portion is provided on the inner wall of the drill rod and located within the groove; A threaded rod is slidably disposed within the groove. After sliding, the threaded rod engages with the threaded portion to drive the drill rod to rotate.

[0011] As a further technical solution, the groove has an opening, and the inner wall of the drill rod is provided with a first smooth portion, a threaded portion, and a second smooth portion sequentially along the direction from near to far from the opening. The threaded portion is located on one side of the disc portion, and the second smooth portion has a through hole. The solution also includes: An insert rod is slidably disposed within the through hole, the sliding direction of the insert rod being perpendicular to the rotation axis of the drill rod, and the insert rod is inserted into the coal wall after sliding.

[0012] As a further technical solution, it also includes: An elastic element is disposed within the through hole. One end of the elastic element is connected to the second smooth part, and the other end is connected to the insertion rod. The elastic element provides the force for the insertion rod to retract into the coal wall.

[0013] As a further technical solution, the threaded rod has a frustum portion at the end away from the opening, and the cross-sectional area of ​​the frustum portion gradually decreases from near to far from the opening. After the threaded rod slides, the frustum portion abuts against or cancels abutment against the insert rod.

[0014] The working principle and beneficial effects of this invention are as follows: In this invention, the entire guide rail is mounted on the drilling rig via a mounting base. The working principle is as follows: When the guide rail slides and extends in preparation for drilling, and to compensate for the distance of the cross-belt operation, to improve the overall stability of the guide rail, it is tightened and locked against the coal wall. The coal wall provides stability to the guide rail and prevents it from swaying. To facilitate rapid tightening and locking of the guide rail against the coal wall, a clamping component is slidably installed on the guide rail. Through manual or electric drive, after the guide rail slides, the clamping component slides first, tightening it against the coal wall. At this time, the first limiting hole of the guide rail and the second limiting hole of the clamping component... The corresponding connection is then made by installing limiting components such as pins, so that they are simultaneously located in the first and second limiting holes. This satisfies the sliding position of the clamping component, ensuring that the clamping component is fixed in position and clamps the coal wall. This clamping force can be stably transmitted to the guide rail. The stable support force provided by the coal wall can be stably transmitted. Compared with the traditional method, the addition of an adjustable clamping component allows for adjustable front clamping. It can also be used in conjunction with a hydraulic cylinder-type drive component that drives the guide rail to automatically clamp the coal wall during cross-belt operation, stabilize the guide rail, reduce shaking, and greatly improve the safety of drilling operations.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-7 As shown, this embodiment proposes an automatic guide rail clamping device for controlling the guide rail 1 to clamp against the coal wall, including: Mounting base 2; The guide rail 1 is slidably disposed on the mounting base 2, and the guide rail 1 has a first limiting hole 101; The top clamping member 3 is slidably disposed on the guide rail 1. The top clamping member 3 has a second limiting hole 301. After sliding, the top clamping member 3 abuts against the coal wall, and the first limiting hole 101 communicates with the second limiting hole 301. The limiting member 4 is located within both the first limiting hole 101 and the second limiting hole 301.

[0019] In this embodiment, the entire guide rail 1 is mounted on the drilling rig via the mounting base 2. The working principle is as follows: When the guide rail 1 slides and extends in preparation for drilling, and to compensate for the distance of the cross-belt operation, to improve the overall stability of the guide rail 1, it is tightened and locked against the coal wall. The coal wall provides stability to the guide rail 1 and prevents it from shaking. To facilitate quick tightening and locking of the guide rail 1 against the coal wall, a clamping member 3 is slidably installed on the guide rail 1. After the guide rail 1 slides, the clamping member 3 is slidably moved first, either manually or electrically, to tighten it against the coal wall. At this time, the first limiting hole 101 of the guide rail 1 and the second limiting hole of the clamping member 3 are... 301 is connected, and then a limiting component 4 in the form of a pin is installed so that it is simultaneously located in the first limiting hole 101 and the second limiting hole 301, satisfying the sliding position of the clamping component 3, ensuring that the position of the clamping component 3 is fixed, clamping the coal wall, and can stably transmit the stable support force provided by the coal wall to the guide rail 1. Compared with the traditional method, the addition of an adjustable clamping component 3 can adjust the front clamping, and can also be used with the driving component 7 in the form of a pushing cylinder that drives the guide rail 1 to achieve automatic clamping of the coal wall when working across the belt, stabilizing the guide rail 1 and reducing shaking, which greatly improves the safety of drilling construction.

[0020] Furthermore, there are two clamping members 3, which are symmetrically arranged on the guide rail 1, and the system also includes: The disc abutment 5 is disposed on the end of the tightening member 3 away from the mounting base 2. After the tightening member 3 slides, the disc abutment 5 abuts against the coal wall.

[0021] In this embodiment, two clamping members 3 are symmetrically arranged along the width direction of the guide rail 1 to achieve better stability of the guide rail 1 during operation; furthermore, a disc abutment member 5 is fixed at the end of the clamping member 3 away from the mounting base 2. The disc-shaped abutment member can increase the contact area with the coal wall and prevent excessive clamping force, which would cause it to directly insert into the coal wall and cause the stabilizing effect to fail.

[0022] Furthermore, it also includes: A limiting cylinder 6 is disposed on the guide rail 1 and located below the first limiting hole 101. The tightening member 3 is slidably disposed inside the limiting cylinder 6. The limiting cylinder 6 has a third limiting hole 601, which communicates with the first limiting hole 101. The limiting member 4 is simultaneously located inside the first limiting hole 101, the second limiting hole 301, and the third limiting hole 601.

[0023] In this embodiment, to improve the sliding stability of the clamping member 3, a limiting cylinder 6 is added to the guide rail 1. The clamping member 3 is slidably disposed in the limiting cylinder 6 and passes through the limiting cylinder 6. At the same time, in order to ensure that the limiting member 4 can properly fix the position of the clamping member 3 and prevent interference from the limiting cylinder 6, the limiting cylinder 6 is designed to have a third limiting hole 601. When the limiting member 4 is installed, it will also pass through the third limiting hole 601.

[0024] Furthermore, the limiting member 4 is a pin, and there are several second limiting holes 301. The several second limiting holes 301 are arranged at intervals along the sliding direction of the tightening member 3. After the tightening member 3 slides, the first limiting hole 101 connects or disconnects from the second limiting hole 301.

[0025] In this embodiment, to adapt to different positions, the second limiting hole 301 of the clamping member 3 can communicate with the first limiting hole 101 on the guide rail 1 to ensure that the limiting member 4 can lock the position of the clamping member 3. The second limiting holes 301 are arranged at intervals along the sliding direction of the clamping member 3.

[0026] Furthermore, the sliding direction of the guide rail 1 is parallel to the sliding direction of the clamping member 3, and the clamping member 3 moves closer to or further away from the mounting base 2 after sliding. It also includes: The driving component 7 has a driving end 701 and is disposed at the bottom of the mounting base 2. The clamping component 3 is connected to the driving end 701.

[0027] In this embodiment, to ensure the stability of the device and the compactness of the overall structure, the sliding direction of the guide rail 1 is set to be parallel to the sliding direction of the clamping member 3, and a driving member 7 is added to the bottom of the mounting base 2, which can be in the form of a pushing cylinder, etc. The driving end 701 is connected to the clamping member 3, and the pushing cylinder is controlled to drive the guide rail 1 to slide closer to the coal wall.

[0028] Furthermore, the clamping member 3 includes: The support cylinder 302 is slidably disposed inside the limiting cylinder 6. The support cylinder 302 has a strip hole 303 and a disc portion 304. The limiting member 4 passes through the strip hole 303. The drill rod 305 is rotatably disposed inside the support cylinder 302. The rotational axis of the drill rod 305 and the sliding direction of the support cylinder 302 are both parallel to the sliding direction of the guide rail 1. The drill rod 305 has a second limiting hole 301. After the support cylinder 302 slides, the disc portion 304 abuts against the coal wall, and the drill rod 305 drills into the coal wall.

[0029] In this embodiment, to further improve the connection stability with the coal wall, a drill rod 305 is added to be inserted into the coal wall, based on the existing disc abutment 5 which increases the contact area. Therefore, the clamping member 3 includes a support cylinder 302 and a drill rod 305. The support cylinder 302 supports and drives the drill rod 305 to slide, thereby clamping the coal wall. The clamping of the coal wall is achieved by the disc part 304 on the support cylinder 302. The strip hole 303 is mainly to prevent interference with the use of the limiting member 4. The drill rod 305 is rotatably mounted on the support cylinder 302. Inside 02, after the disc part 304 is pressed against the coal wall and the drill rod 305 is drilled into the coal wall, the strip hole 303 and the second limiting hole 301 on the drill rod 305 can be connected by the limiting member 4 to the first limiting hole 101. The limiting member 4 passes through the strip hole 303. At this time, the drill rod 305 is actually limited, and the support cylinder 302 can still move relative to the limiting member 4. Furthermore, the support cylinder 302 and the limiting member 4 can be fixedly connected by bolts and other fasteners to ensure that the coal wall stabilizes the guide rail 1 together through the drill rod 305 and the support cylinder 302.

[0030] Furthermore, the drill rod 305 also has a groove 306, the groove 306 being axially collinear with the axial direction of the drill rod 305, and further includes: A threaded portion 8 is provided on the inner wall of the drill rod 305 and located within the groove 306; The threaded rod 9 is slidably disposed in the groove 306. After sliding, the threaded rod 9 engages with the threaded part 8 and is used to drive the drill rod 305 to rotate.

[0031] In this embodiment, to save costs, instead of actively driving the drill rod 305 to rotate using a motor or other devices, a threaded connection is directly used. The threaded rod 9 is manually pushed into the groove 306 provided along the axial direction of the drill rod 305. When the threaded rod 9 is pushed into the threaded part 8 inside the groove 306, it will drive the drill rod 305 to rotate, which facilitates the sliding of the support cylinder 302 to drive it to drill into the coal wall until the disc part 304 abuts against the coal wall.

[0032] Furthermore, the groove 306 has an opening 307, and the inner wall of the drill rod 305 is provided with a first smooth portion 10, a threaded portion 8, and a second smooth portion 11 sequentially along the direction from near to far from the opening 307. The threaded portion 8 is located on one side of the disc portion 304, and the second smooth portion 11 has a through hole 1101. It also includes: Insert rod 12 is slidably disposed in the through hole 1101. The sliding direction of the insert rod 12 is perpendicular to the rotation axis of the drill rod 305. After sliding, the insert rod 12 is inserted into the coal wall.

[0033] In this embodiment, not all of the groove 306 is provided with threaded portions 8. The first smooth portion 10, the threaded portion 8, and the second smooth portion 11 are arranged sequentially from the direction closest to the opening 307 away from the opening. The threaded portions 8 at fixed intervals can control the drill rod 305 to a fixed rotation angle, thus facilitating the connection between the first limiting hole 101 and the second limiting hole 301 after each rotation, without having to adjust the rotation angle each time to make the two connected. Furthermore, a through hole 1101 is opened in the second smooth portion 11, and the insertion rod 12 slides in the through hole 1101. When the drill rod 305 is inserted into the coal wall, the insertion rod 12 will also be inserted vertically, further improving the connection stability between the drill rod 305 and the coal wall.

[0034] Furthermore, it also includes: An elastic element 13 is disposed within the through hole 1101. One end of the elastic element 13 is connected to the second smooth part 11, and the other end is connected to the insertion rod 12. The elastic element 13 provides the insertion rod 12 with a force to retract into the coal wall.

[0035] Furthermore, the threaded rod 9 has a frustum 901 at the end away from the opening 307. The cross-sectional area of ​​the frustum 901 gradually decreases from near to far from the opening 307. After the threaded rod 9 slides, the frustum 901 abuts against or cancels abutment against the insert rod 12.

[0036] In this embodiment, to facilitate the insertion of the insertion rod 12 into the coal wall under the action of the threaded rod 9, and to save costs by eliminating the need for an additional motor, the threaded rod 9 is provided with a frustum 901 at the end away from the opening 307. The cross-sectional area of ​​the frustum 901 is designed so that as the threaded rod 9 extends into the groove 306, it will slowly abut against and push the insertion rod 12 into the coal wall. At the same time, to facilitate the removal of the whole assembly and to give the insertion rod 12 a repositioning ability, an elastic element 13 is installed in the through hole 1101. The elastic element 13 connects the second smooth part 11 and the insertion rod 12, providing a force to retract into the coal wall and improving the overall practicality.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
