Description

Technical Field

[0001] This invention relates to the field of tunnel support technology, and in particular to a tunnel anchor support device. Background Technology

[0002] Currently, after a cantilever roadheader cuts through the coal and rock strata at the face of a coal mine tunnel, it is necessary to promptly anchor the newly cut tunnel roof area to improve the stability of the surrounding rock. Anchor support requires drilling and installation of anchor bolts using an anchor bolt drilling machine.

[0003] Currently, the main method of coal mine roadway support in my country is bolt support. Coal mining follows a sequence of excavation-bolt support-excavation, meaning that after the tunneling machine cuts through a section of coal and rock, it stops and withdraws, and bolt support is then applied to the newly excavated coal mine roadway manually or mechanically. Currently, coal mine roadway support operations mainly rely on single bolt drilling rigs and vehicle-mounted bolt drilling rigs. Single bolt drilling rigs require manual operation, which is labor-intensive, dangerous, and difficult to directly apply to large roadways. Vehicle-mounted bolt drilling rigs, on the other hand, require wider roadways for passing, and the alternating support and excavation process is cumbersome. Both single bolt drilling rigs and vehicle-mounted bolt drilling rigs require the tunneling machine to stop and withdraw before support operations can begin, which cannot provide timely support and reduces the speed of coal mine roadway excavation. Summary of the Invention

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] The purpose of this invention is to provide a roadway anchor support device to solve the problems existing in the prior art. The tunneling machine and the anchor support device can operate in parallel, so that the roadway can be supported in a timely manner and the roadway excavation efficiency can be improved.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] This embodiment provides a roadway anchor support device 1. Please refer to [link / reference]. Figures 1-3 The system includes a guide rail mechanism 10, a propulsion mechanism 20, a moving platform 30, an upper support mechanism 40, a lower support mechanism 50, and an adjustment mechanism 60. The guide rail mechanism 10 is fixedly installed on the top of the roadway 2 along the tunneling direction. The propulsion mechanism 20 is connected to the guide rail mechanism 10, and the propulsion mechanism 20 can move relative to the guide rail mechanism 10 along the tunneling direction and can be fixed in its relative position to the guide rail mechanism 10. The moving platform 30 is installed at the front end of the propulsion mechanism 20 along the tunneling direction and is connected to the propulsion mechanism 20. The propulsion mechanism 20 can push the moving platform 30 along the tunneling direction. The upper support mechanism 40 is mounted on the moving platform 30 and is used to support the top of the tunnel 2; the lower support mechanism 50 is mounted on the moving platform 30 and is used to support the bottom plate of the tunnel 2 on both sides of the tunneling machine 3; the adjusting mechanism 60 is movably mounted on the moving platform 30 at one end along the tunneling direction, and the other end is provided with a working mechanism 70. The adjusting mechanism 60 can move relative to the moving platform 30 along the tunneling direction and fix its relative position with the moving platform 30. The adjusting mechanism 60 can also adjust its own length in the tunneling direction to adjust the position of the working mechanism 70.

[0036] By installing a guide rail mechanism 10 at the top of tunnel 2, the entire support device can operate in the space above tunnel 2, thus enabling synchronous operation with the tunneling machine 3. The propulsion mechanism 20 moves relative to the guide rail mechanism 10 along the tunneling direction and can be fixed in its relative position to the guide rail mechanism 10, so as to advance synchronously with the tunneling operation of the tunneling machine 3. The moving platform 30 can move forward under the action of the propulsion mechanism 20. At the same time, the upper support mechanism 40 on the moving platform 30 can support the top of tunnel 2, and the lower support mechanism 50 on the moving platform 30 can support the bottom plates of the side walls of tunnel 2 on both sides of the tunneling machine 3, improving operational stability and enabling... To avoid interference with the working space required by the tunneling machine 3, the working mechanism 70, like a conventional anchor bolt support mechanism, is connected to the mobile platform 30 via an adjusting mechanism 60. The adjusting mechanism 60 can move relative to the mobile platform 30 along the tunneling direction and maintain its relative position, thereby increasing the working range of the front end of the working mechanism 70. Furthermore, the adjusting mechanism 60 itself can adjust its length along the tunneling direction to further increase the working range of the front end of the working mechanism 70, enabling the working mechanism 70 to keep pace with the tunneling progress of the tunneling machine 3 and provide timely support for the roadway 2. The tunneling direction is the overall direction of tunnel excavation. Figure 2 , Figure 4 and Figure 5 The direction from right to left in the middle, and Figure 4 The direction indicated by the middle arrow is a specific tunneling path for tunneling machine 3.

[0037] In the optional scheme of this embodiment, more preferably, the guide rail mechanism 10 includes multiple anchor bolts 11 and multiple I-beams 12 fixedly distributed on the top of the roadway 2 along the tunneling direction. The multiple I-beams 12 are fixed by the anchor bolts 11 and form a guide rail along the tunneling direction. The propulsion mechanism 20 is connected to the guide rail. The tunneling machine 3 pre-cuts a portion of the roadway 2 and pre-anchors the anchor bolts 11 on the top of the pre-cut roadway 2. The exposed sections of the anchor bolts 11 are sequentially installed as guide rails to cooperate with the propulsion mechanism 20. By pre-cutting to a cut area that can accommodate the tunneling roadway anchor bolt support device 1 to enter the work without interfering with the tunneling machine 3 cutting the coal seam, the working mechanism 70 can move to the newly cut area to perform support operations such as drilling anchor bolt holes. This achieves parallel operation of the tunneling machine 3 cutting the coal seam and the working mechanism 70 drilling holes for support, without interference between them.

[0038] In the optional solutions of this embodiment, a more preferred option is described in the following description: Figure 1 and Figure 2 The propulsion mechanism 20 includes a first propulsion member 21, a second propulsion member 22, and a sliding trolley 23 arranged sequentially along the tunneling direction. One end of the first propulsion member 21 facing away from the second propulsion member 22 is connected to the guide rail mechanism 10 via a first connecting seat 24. The other end of the second propulsion member 22 facing away from the sliding trolley 23 is connected to the guide rail mechanism 10 via a second connecting seat 25. The other end of the first propulsion member 21 is connected to the second connecting seat 25, and the second propulsion member 22 is connected to the sliding trolley 23. The sliding trolley 23 is connected to the moving platform 30 and is slidably connected to the guide rail mechanism 10. Locking components 26 are provided on both the first connecting seat 24 and the second connecting seat 25, and both the first connecting seat 24 and the second connecting seat 25 are slidably connected to the guide rail mechanism 10. On the 0, each locking component 26 can lock the relative position of the corresponding first connecting seat 24 or second connecting seat 25 with the guide rail mechanism 10; the first propulsion component 21 and the second propulsion component 22 can both adjust their own length in the tunneling direction to drive the sliding steer 23 and the moving platform 30 to move relative to the guide rail mechanism 10 in the tunneling direction; by setting the first propulsion component 21 and the second propulsion component 22 to adjust their own length in sequence, and cooperating with the locking component 26 to lock the first connecting seat 24 and the second connecting seat 35 in sequence, the sliding steer 23 can move forward along the guide rail mechanism 10 in sequence, thereby pushing the moving platform 30, the upper support mechanism 40, the lower support mechanism 50, the adjustment mechanism 60 and the working mechanism 70 to move forward synchronously, so as to realize the timely support of the roadway 2.

[0039] Specifically, the first propulsion member 21 and the second propulsion member 22 can be configured as propulsion hydraulic cylinders, which can adjust their own length and lock them. Both ends of the first propulsion member 21 and the second propulsion member 22 are respectively hinged to the corresponding components to facilitate propulsion. In addition, it should be noted that the first propulsion member 21 and the second propulsion member 22 can also be configured as electric telescopic rods, as long as they can adjust their own length and lock them.

[0040] Furthermore, the first propulsion member 21, the second propulsion member 22, the first connecting seat 24, and the second connecting seat 25 can be symmetrically configured as two sets, arranged side by side along the width direction of the guide rail mechanism 10 to improve stability.

[0041] Specifically, the first connecting seat 24, the second connecting seat 25, and the sliding carriage 23 are slidably fitted onto the lower flange plate of the I-beam 12; please refer to Figure 10 and Figure 11The locking assembly 26 includes a locking drive 261, a plug rod 262, a support pulley 263, a support spring 264, a guide telescopic member 265, a slider 266, and a traveling pulley. Two locking drive members 261 are provided, located on both sides of the I-beam 12, with one end fixedly connected to the inner sidewall of the side plates of the first connecting seat 24 or the second connecting seat 25. The other end of each locking drive member 261 is provided with a support pulley 263 to support the sidewall of the I-beam 12, thus supporting its movement. The first connecting seat 24 or the second connecting seat 25... The inner walls of both side plates of the connecting seat 25 are provided with insert rods 262. Multiple slots 121 are pre-set along the length of the web of the I-beam 12. Two insert rods 262 on the first connecting seat 24 or the second connecting seat 25 can be staggered and inserted into two slots 121 for locking. Furthermore, the inner walls of both side plates of the first connecting seat 24 or the second connecting seat 25 are also provided with traveling pulleys 267 that can travel and be supported on the lower flange of the I-beam 12. The inner walls of the two side plates of the first connecting seat 24 or the second connecting seat 25 are fixedly connected... A guide telescopic component 265 is provided, and a support spring 264 fixedly connected to the two side plates is provided on the outer sleeve of the guide telescopic rod 265. A slider 266 that cooperates and slides between the inner side walls of the two side plates of the first connecting seat 24 or the second connecting seat 25 is also provided. Specifically, the two locking drive components 261 can adjust their own length to drive the two side plates of the first connecting seat 24 or the second connecting seat 25 to move closer or further away from each other, so that the insertion rod 262 can be inserted into or pulled out of the slot 121 to lock or unlock. During this process, the two sliders 266 slide against each other to play a guiding role. When the locking drive component 261 drives the two side plates of the first connecting seat 24 or the second connecting seat 25 to move away from each other, it can stretch the support spring 264 and simultaneously drive the guide telescopic component 265 to extend. During the return process, the support spring 264 can assist the two side plates of the first connecting seat 24 or the second connecting seat 25 to move closer to each other, and the guide telescopic component 265 can support the deformation of the support spring 264 to ensure the direction of the force of the support spring 264.

[0042] Specifically, the locking drive component 261 is configured as a hydraulic cylinder, and the guide telescopic component 265 can be configured as a passively telescopic rod; in addition, it should be noted that the locking component 26 can also be configured as other conventional electromagnetic chuck mechanisms, and the opening and closing of the first connecting seat 24 or the second connecting seat 25 and the guide rail mechanism 10 can be realized by electronic control.

The lifting mechanism 80 is connected to both the propulsion mechanism 20 and the moving platform 30. The lifting mechanism 80 can adjust its own length to adjust and fix the vertical position of the moving platform 30. By adjusting the vertical position of the moving platform 30, the vertical positions of the moving platform 30, the upper support mechanism 40, the lower support mechanism 50, the adjusting mechanism 60 and the working mechanism 70 can be adjusted, thereby improving flexibility.

Specifically, each rotatable connection can be configured as a hinge. Both the drive component 81 and the connecting support component 82 include two hydraulic cylinders arranged along the direction of the roadway 2. The stability of the drive support is improved by each having two hydraulic cylinders. The lifting drive component 81 can be tilted to facilitate lifting. The first linkage assembly 83 is rotatably connected to both the moving platform 30 and the sliding steer 23, improving the stability of the connection between the moving platform 30 and the sliding steer 23. In addition, it should be noted that the lifting drive component 81 and the connecting support component 82 can also be configured as other structures that can adjust their own length, such as electric telescopic rods. They are not limited to the above structures, as long as they can adjust their own length and be locked.

By driving the support beams 41 for support, the stability of the top of the tunnel 2 and the support operation is improved.

[0047] Specifically, each rotating connection of the upper support mechanism 40 can be configured as a hinge, and the number of support beams 41 can be set to two to improve the stability of the support. Multiple weight-reducing holes can be provided on the support beams 41 to reduce the overall weight. The front support member 42 and the rear support member 43 can be configured as hydraulic cylinders, which can adjust their own length and lock them. Both the front support member 42 and the rear support member 43 can be tilted forward, which, together with the second linkage assembly 44, facilitates the lifting and lowering adjustment of the support beams 41. In addition, it should be noted that the front support member 42 and the rear support member 43 are not limited to the above structure.
