The application of these new support materials and support forms has significantly improved the support effect, material consumption, and construction efficiency of the end supports along the empty tunnel. The anchor cable hiding mechanism of the end support of the empty tunnel is mainly composed of an electro-hydraulic control system, a top beam, a top guard beam, a four-link, a hydraulic column, and other parts.

[0029] Specifically, the second driving mechanism 12 has the same structure as the first driving mechanism 4 , and the second driving mechanism 12 and the first driving mechanism 4 are arranged in a left-right mirror image.

[0030] In this embodiment, the second driving mechanism 12 can drive the rear anchor cable mechanism 14 on the upper surface of the rear base 11 to move left and right.

[0031] Specifically, the front anchor cable mechanism 6 includes a rectangular box 601, a lifting hole 602, a manual linear module 603, a rectangular cover 604, a hinge 605 and a connecting rod 606. The rectangular box 601 is fixedly installed on the upper surface of the first mounting plate 5. The front and rear side walls of the rectangular box 601 are provided with lifting holes 602. Two manual linear modules 603 are mirror-imaged on the lower inner wall of the rectangular box 601, and the front and rear manual linear modules 603 are fixedly connected by screw rods. The left and right sides of the manual linear module 603 slide and the lower surface of the rectangular cover 604 are provided with hinges 605, and the upper and lower corresponding hinges 605 are connected by a connecting rod 606.

[0032] In this embodiment, the front and rear lifting holes 602 of the rectangular box 601 facilitate the lifting of the front anchor cable mechanism 6, and the front and rear manual linear module 603 slides drive the connecting rod 606 to move through the lower hinge 605, so that the connecting rod 606 drives the inner wall of the rectangular cover 604 to move up and down along the outer surface of the rectangular box 601 through the upper hinge 605, thereby achieving the effect of adjusting the height of a single front anchor cable mechanism 6.

[0033] Specifically, the screw rod of the manual linear module 603 is arranged corresponding to the hanging hole 602 , and a hexagonal hole 20 is opened on the side of the screw rod of the manual linear module 603 facing the hanging hole 602 .

[0034] In this embodiment, the hexagonal hole 20 facilitates the insertion of the hexagonal wrench into the screw rod of the manual linear module 603 through the hanging hole 602, so that the hexagonal wrench drives the screw rod of the manual linear module 603 to rotate.

[0035] Specifically, the rear dodging anchor cable mechanism 14 and the fixed dodging anchor cable mechanism 16 have the same structure as the front dodging anchor cable mechanism 6.

[0036] In this embodiment, both the rear anchor cable mechanism 14 and the fixed anchor cable mechanism 16 have a supporting function and can be independently adjusted in height.

[0037] Specifically, the second connecting mechanism 10 includes a second fastening bolt 101 and a second elongated hole 102. The second fastening bolt 101 is arranged between the upper and lower side walls of the shielding beam 9 near the left and right positions, and a second elongated hole 102 is opened on the rear base 11 corresponding to the second fastening bolt 101. The second fastening bolt 101 passes through the second elongated hole 102 to lock and fix the rear base 11.

[0038] In this embodiment, the second fastening bolt 101 passes through the second elongated hole 102 to lock and fix the rear base 11, thereby achieving the effect of fixing the rear base 11 to the upper surface of the shielding beam 9. At the same time, the rear base 11 moves left and right along the second fastening bolt 101 through the second elongated hole 102, thereby achieving the effect of adjusting the left and right initial position of the rear base 11.

[0039] The working principle and use process of the present invention are as follows: when in use, the front base 3 is locked and fixed by passing the first fastening bolt 201 in the first connecting mechanism 2 through the first long hole 202, so as to achieve the effect of fixing the front base 3 to the upper surface of the top beam 1, that is, installing and fixing the front hiding anchor cable mechanism 6, and then the rear base 11 is locked and fixed by passing the second fastening bolt 101 in the second connecting mechanism 10 through the second long hole 102, so as to achieve the effect of fixing the rear base 11 to the upper surface of the shielding beam 9, that is, installing and fixing the rear hiding anchor cable mechanism 14, and fixing the hiding anchor cable mechanism 16 to the extension beam 9. On the contraction beam assembly 15, the telescopic jack 402 in the first driving mechanism 4 is connected to the front base 3 and the first mounting plate 5 through the first pin assembly 401 and the second pin assembly 403. The output shaft of the telescopic jack 402 drives the first mounting plate 5 to move left and right through the second pin assembly 403, and the first mounting plate 5 drives the front anchor cable mechanism 6 to move left and right. During the left and right movement of the first mounting plate 5, the first mounting plate 5 moves left and right along the guide rail 404 through the guide groove 405, so that the left and right movement of the first mounting plate 5 is stable, that is, the left and right movement process of the front anchor cable mechanism 6 is stable. Similarly, The rear anchor cable mechanism 14 on the upper surface of the second mounting plate 13 is driven to move left and right by the second driving mechanism 12, and the telescopic beam assembly 15 drives the fixed anchor cable mechanism 16 to move left and right, thereby solving the problem of conflict between the anchor cable mechanism of the hydraulic support at the end of the empty lane and the lane anchor cable. The anchor cable mechanism is cleverly moved forward and backward to the appropriate position of the support to avoid direct conflict with the anchor cable, which is convenient for installing and fixing the hydraulic support. The hexagonal hole 20 is convenient for the hexagonal wrench to be inserted into the manual linear module 603 screw rod in the front anchor cable mechanism 6 through the lifting hole 602, so that the hexagonal wrench drives the manual linear module 603 screw rod to move left and right. The screw rod of the linear module 603 rotates, so that the front and rear manual linear module 603 slides drive the connecting rod 606 to move through the lower hinge 605, so that the connecting rod 606 drives the inner wall of the rectangular cover 604 to move up and down along the outer surface of the rectangular box 601 through the upper hinge 605, thereby achieving the effect of adjusting the height of a single front dodging anchor cable mechanism 6. Similarly, the rear dodging anchor cable mechanism 14 and the fixed dodging anchor cable mechanism 16 can be adjusted in height separately, so that the front dodging anchor cable mechanism 6, the rear dodging anchor cable mechanism 14 and the fixed dodging anchor cable mechanism 16 have better supporting effects, and the hydraulic support support force is more uniform, ensuring the support effect.

[0040] In summary, the mining hydraulic support anchor cable avoiding device solves the problem of conflict between the anchor cable avoiding mechanism of the hydraulic support at the end of the goaf and the anchor cable of the roadway, and cleverly moves the anchor cable avoiding mechanism forward and backward to the appropriate position of the support through the telescopic jack 402 to avoid direct conflict with the anchor cable, while making the support force more uniform to ensure the support effect.
