[0003] Currently, the hooks on the market generally consist of a hook angle, a hook body, and an insulating protection sheet. Due to the structural limitations of the hooks, when installing the hooks on the steel strands, operators need to climb ladders or use pulleys to install them manually. During this process, the installation process of traditional optical cable hooks is relatively cumbersome, the assembly efficiency is low, and the safety of operators during high-altitude operations is difficult to guarantee, and safety accidents are likely to occur.

[0027] The following further elaborates on the present invention in detail with reference to the accompanying drawings of the specification. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0028] As Figures 1 to 7As shown in the figure, the present invention proposes a multi-stage lifting type optical cable hook twisting and hanging device, which includes a front frame 12, a middle frame 13 and a rear frame 14 connected in sequence. A lifting component 10, a displacement component 11 and a fixed bin 16 are arranged on the middle frame 13. The hook 22 is lifted to the displacement component 11 through the lifting component 10, and then the hook 22 is pushed to the fixed bin 16 through the displacement component 11. The rear frame 14 is in a hollow circular shape, facilitating the hook 22 to pass through the middle of the rear frame 14. Locking columns 15 are provided on both the front frame 12 and the rear frame 14. Both the front frame 12 and the rear frame 14 are sleeved on the steel strand 21, and the top of the front frame 12 and the rear frame 14 are connected through the locking columns 15.

[0029] An elevating motor 5 and a support frame 6 are also arranged on the middle frame 13. The support frame 6 is in a square frame structure. A threaded column 62 is arranged on the support frame 6. A threaded sleeve 61 is movably sleeved on the threaded column 62. The threaded sleeve 61 is fixedly connected with a lifting main arm 63. The elevating motor 5 is connected with a belt pulley assembly 52. The belt pulley assembly 52 cooperates with the threaded column 62 to move. The threaded column 62 can rotate forward or backward, so that the threaded sleeve 61 moves up and down through the rotation of the threaded column 62. A lithium battery 51 is installed on the elevating motor 5 to supply power to the elevating motor 5.

[0030] The fixed bin 16 includes a fixed seat 83. A gripper is arranged at the front end of the lifting main arm 63. The fixed seat 83 is cylindrical and inserted into the gripper at the front end of the lifting main arm 63. The fixed seat 83 is cylindrical and inserted at the front end of the lifting main arm 63. Lifting auxiliary arms 8 are welded on both sides of the fixed seat 83. The lifting auxiliary arms 8 are in the shape of two square strips, and racks 81 are embedded inside. A motion motor 9 is used in cooperation with the racks 81. The motion motor 9 meshes with the racks 81. Side clamping blocks 91 are fixedly sleeved on the lifting auxiliary arms 8. The side clamping blocks 91 are driven to close or separate towards the middle of the fixed seat 83 through the meshing of the motion motor 9 and the racks 81. Side clamping bins 92 are arranged on the side clamping blocks 91. Grooves capable of accommodating the hook 22 are arranged on the sides of the side clamping bins 92. The hook 22 is pressed on both sides through the side clamping bins 92 on the side clamping blocks 91. In this embodiment, the lifting main arm 63 and the lifting auxiliary arms 8 are vertically in a T shape in the initial state.

[0031] A fixing column 3 and a protection piece 4 are arranged on the hook 22. The protection piece 4 is made of plastic material. The fixing column 3 is cylindrical and arranged at the bottom of the hook 22. A main clamping bin 82 is arranged in the middle of the fixed seat 83. The fixing column 3 at the bottom of the hook 22 is embedded in the main clamping bin 82.

[0032] There are two opposite menisci 7 provided on the middle frame 13, and a first-stage torsion groove 71, a second-stage torsion groove 72, and a third-stage torsion groove 73 are respectively provided on the inner side surfaces of the menisci 7. The first-stage torsion groove 71, the second-stage torsion groove 72, and the third-stage torsion groove 73 are connected through. Sliding columns 84 are provided at both ends of the lifting auxiliary arm 8. The sliding columns 84 are circular and move in the first-stage torsion groove 71, the second-stage torsion groove 72, and the third-stage torsion groove 73 in sequence. In this embodiment, the cross-section of the meniscus 7 is an arc segment, and the two menisci 7 are arranged and installed on the middle frame 13 with the longitudinal axis of the fixed seat 83 as the center of the circle.

[0033] During actual use, first, the front frame 12 and the rear frame 14 are both sleeved on the steel strand 21. The middle frame 13 hangs vertically below the optical cable 2 and the steel strand 21 arranged in parallel up and down. At the same time, the fixed column 3 at the bottom of the hook 22 will engage in the main clamping bin 82 in the middle of the fixed seat 83. At this moment, the hook 22 is positioned. Next, the two moving motors 9 are started. The moving motors 9 engage and move with the rack 81. The side clamping blocks 91 are driven to move towards the middle of the fixed seat 83 through the engagement of the moving motors 9 and the rack 81. Fold in. The side clamping bin 92 on the side clamping block 91 is used to press both sides of the hook 22. At this moment, the hook 22 is limited. The lithium battery 51 supplies power to the lifting motor 5 to drive the threaded column 62 on the pulley assembly 52 to rotate forward. At this moment, the threaded sleeve 61 drives the lifting main arm 63 to lift. At the same time, the lifting main arm 63 drives the fixed seat 83 to lift. During this process, the lifting auxiliary arms 8 on both sides of the fixed seat 83 also generate a torsional movement during the process of following the fixed seat 83 to lift, that is, the sliding columns 84 at both ends of the lifting auxiliary arm 8 move in the first-stage torsion groove 71, the second-stage torsion groove 72, and the third-stage torsion groove 73 in sequence. When the sliding column 84 transitions from the second-stage torsion groove 72 to the first-stage torsion groove 71, the lifting auxiliary arm 8 drives the hook 22 to move. The hook 22 breaks through the natural state of the optical cable 2 and the steel strand 21 in a parallel up and down state through the shape and torsional movement at both ends of itself, so that the hook 22 drives the optical cable 2 to be torsionally hung on the steel strand 21. And the reverse movement drives the side clamping block 91 to disengage from the hook 22 and then reset. Next, the lifting motor 5 rotates in reverse to drive the lifting main arm 63 and the lifting auxiliary arm 8 to reset to the initial position. After a person pulls the pull rope 1 on the ground to drive the multi-stage lifting type optical cable hook torsionally hanging device to move forward for a certain distance, continue to repeat the above steps to torsionally hang the hook 22.

Any person familiar with this technology can easily implement it within the scope described in this application. Any changes or substitutions that do not change the basic principles involved in the claims should be covered within the protection scope of this application. That is, the protection scope of this application should be subject to the protection scope of the claims.
