[0001] The invention relates to the technical field of anchor cable threading methods, and in particular to a construction method for threading a prestressed anchor cable through an anchor cable hole. Background Art

[0002] When reinforcing the slope through anchor cable construction, the anchor cable must first be lowered into the anchor cable holes drilled in the anti-slip piles and the slope rock layer. In order to facilitate the workers to operate the anchor cable lowering, it is necessary to continuously ensure the cable movement during construction.

[0003] At present, the cable is mostly advanced by manually using tools. Manual advancement is to push the anchor cable through manual operation. This method requires the operator to have certain physical strength and skills.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0019] In order to achieve the above purpose, Figure 1-4The present invention discloses a construction method for inserting a prestressed anchor cable into an anchor cable hole. The device used in the construction method for inserting a prestressed anchor cable into an anchor cable hole comprises a base frame 1, side frames 2 are fixed to both sides of the top of the base frame 1, a common crossbeam 3 is fixed to the top of the two side frames 2, and a pushing mechanism 9 is installed at the bottom of the crossbeam 3; The pushing mechanism 9 includes two electric telescopic rods 10 fixed at the bottom of the beam 3. The output end of the electric telescopic rod 10 is installed with a mounting plate 13 through a connecting piece. A moving block 21 is slidably provided on the mounting plate 13. The moving block 21 is fixed with a fixing ring 25 through a connecting rod 24. The two connecting rods 24 are staggered.

[0020] In the disclosed embodiment, the connecting member includes a mounting block 11 fixed to the output end of the electric telescopic rod 10 , a mounting plate 12 is fixed to the bottom of the mounting block 11 , and a mounting disc 13 is fixed to the mounting plate 12 .

[0021] In the disclosed embodiment, a slide groove 14 is formed on the mounting plate 13 , and a slider 22 is fixed to the outer wall of the moving block 21 . The slider 22 is slidably disposed in the slide groove 14 .

[0022] In the embodiment of the present disclosure, both ends of the outer wall of the beam 3 are slidably provided with a sliding member 15, and the sliding member 15 includes a fixed arm 16, a folded angle rod 19 is fixed to the bottom of the fixed arm 16, and a stopper 20 is fixed to the top of the folded angle rod 19. The folded angle rod 19 is arranged in a one-to-one correspondence with the moving block 21. A top of the fixed arm 16 is fixed with a head 26, and a fixed disk 27 is rotatably provided on the top of the beam 3. The outer wall of the fixed disk 27 is fixed with two symmetrical fork rods 28, and the head 26 passes through the corresponding fork rods 28. Under the action of the fixed disk 27 and the fork rod 28, the entire sliding member 15 remains stationary, so that The moving block 21 can slide upward along the angle rod 19. At this time, the fixed ring 25 moves upward to lift the rope. At this time, the moving block 21 located on the angle rod 19 keeps moving, and the corresponding electric telescopic rod 10 works to realize its advancement. The sliding member 15 and the fixed ring 25 move at the same time, and the fixed disk 27 rotates. At the same time, the other electric telescopic rod 10 retracts to pull the other fixed ring 25 downward and move in the opposite direction. That is to say, one electric telescopic rod 10 pushes the corresponding fixed ring 25 forward, and the other electric telescopic rod 10 pulls the corresponding fixed ring 25 backward, thereby realizing alternation.

[0023] In the embodiment of the present disclosure, a limiting block 17 is fixed to the outer wall of the fixed arm 16 , and a limiting groove 18 for the limiting block 17 to slide is formed on the outer wall of the crossbeam 3 .

[0024] In the embodiment of the present disclosure, a plurality of rollers 23 are rotatably provided at the bottom of the moving block 21 .

[0025] In the disclosed embodiment, a first hook 7 and a second hook 8 are fixed to both sides of the bottom of the beam 3 , respectively.

[0026] In the disclosed embodiment, a cross bar 4 is fixed to the inner wall of the side frame 2, a U-shaped frame 5 is fixed on the cross bar 4, a guide roller 6 is rotatably provided on the U-shaped frame 5, a first hook 7, a second hook 8 and two guide rollers 6 are provided, the rope passes through the guide roller 6, and is hung by the first hook 7 and the second hook 8, ensuring that the rope maintains a certain height of movement.

[0027] A construction method for passing a prestressed anchor cable through an anchor cable hole comprises the following steps: Step 1: The rope passes through the second hook 8, the guide roller 6, the two fixing rings 25 and the first hook 7 from one side; Step 2: The two electric telescopic rods 10 work together. One electric telescopic rod 10 pushes the corresponding fixed ring 25 forward, and the other electric telescopic rod 10 pulls the corresponding fixed ring 25 backward, thereby achieving alternation. When pushing forward, the fixed ring 25 moves up, and when moving backward, the fixed ring 25 moves down.

[0028] Working principle: Due to the use of a pushing mechanism 9 installed at the bottom of the beam 3, the cable passes through the second hook 8, the guide roller 6, the two fixed rings 25 and the first hook 7 from one side, and the two electric telescopic rods 10 work together. First, the mounting block 11 on one of the electric telescopic rods 10 drives the mounting plate 13 to move. Under the action of the mounting plate 13, the moving block 21 and the fixed ring 25 move synchronously. Since the other electric telescopic rod 10 is not working, under the action of the fixed plate 27 and the fork rod 28, the entire sliding member 15 remains stationary, so that the moving block 21 can slide up along the angle rod 19. At this time, the fixed ring 25 moves up to lift the cable. At this time, the moving block 21 located on the angle rod 19 keeps moving, and the corresponding electric telescopic rod 10 works to realize its advancement. The sliding member 15 and the fixed ring 25 move at the same time, and the fixed disk 27 rotates. At the same time, the other electric telescopic rod 10 retracts to pull the other fixed ring 25 downward and move in the opposite direction. That is to say, one electric telescopic rod 10 pushes the corresponding fixed ring 25 forward, and the other electric telescopic rod 10 pulls the corresponding fixed ring 25 backward, thereby realizing alternation. When pushing forward, the fixed ring 25 moves up, and when moving backward, the fixed ring 25 moves down, which effectively solves the problems raised in the background technology, realizes the continuous advancement of the rope, and ensures the forward movement of the rope.
