[0030] Such as Figures 1 to 6As shown in the figure, the special ladder for the conductor clamping device of the tensioning machine includes: a telescopic ladder 1, a fixed column 101 is arranged on the outer side of the telescopic ladder 1, a connecting rope 102 is arranged on the outer side of the fixed column 101, and an anti-falling device 103 is arranged on the outer side of the connecting rope 102; a fixing component 2, which is arranged on the outer side of the telescopic ladder 1 and is used to connect the telescopic ladder 1 with the conductor; a locking mechanism, which is arranged inside the fixing component 2 and is used to fix the position of the fixing component 2. The locking mechanism includes a moving component 3 and a telescopic component 4. The moving component 3 is arranged inside the fixing component 2, and the telescopic component 4 is arranged on the outer side of the moving component 3. The moving component 3 cooperates with the telescopic component 4 to clamp the conductor. Specifically, when in use, first unfold the telescopic ladder 1, and then hook the telescopic ladder 1 with the conductor through the fixing component 2 to ensure the stability of the connection between the telescopic ladder 1 and the conductor during use. During the process of hooking the fixing component 2 with the conductor, through the cooperation of the moving component 3 and the telescopic component 4, the conductor is fixed to the fixing component 2 to prevent the fixing component 2 from moving relative to the conductor during the connection process and ensure the stability of the telescopic ladder 1 during use. The telescopic ladder 1 can be extended according to the height of the conductor during use, and the telescopic ladder 1 is made of aluminum alloy. The anti-falling device 103 provides anti-falling protection for the climbing personnel through the cooperation of the connecting rope 102 and the safety belt to prevent the climbing personnel from falling during the climbing process. The anti-falling device 103 and the telescopic ladder 1 are both prior arts and will not be elaborated here.

[0031] As Figures 1 to 6 shown, the fixing component 2 wraps the hook 201. The hook 201 is arranged at the telescopic end of the telescopic ladder 1 and is connected to the telescopic ladder 1. A sliding groove 202 is arranged inside, and a guiding groove 204 and a groove 203 are respectively arranged inside the sliding groove 202. There are multiple guiding grooves 204 and multiple grooves 203. The opening direction of the guiding groove 204 is perpendicular to the opening direction of the groove 203. Specifically, the outer side of the hook 201 is wrapped with a rubber pad. The hook 201 and the telescopic ladder 1 can be connected by a buckle or a thread, so that ladders of different lengths can be rotated according to actual needs during use to avoid damaging the conductor during use. The hook 201 is connected to the top of the telescopic ladder 1. When in use, the hook 201 is controlled by the telescopic ladder 1 to hook the conductor to prevent the telescopic ladder 1 from separating from the conductor during use and ensure the stability during use. The guiding groove 204 guides the moving direction of the telescopic component 4 to ensure that the telescopic component 4 can accurately clamp the conductor during use.

[0032] As Figures 1 to 6As shown, the moving component 3 includes a sliding block 301. The sliding block 301 is arranged inside the sliding groove 202 and moves relative to the hook 201. A plurality of springs 302 are provided on the side of the sliding block 301 relative to the groove 203. The springs 302 correspond to the groove 203 and are connected to the hook 201. An installation groove is formed on the other side of the sliding block 301. Specifically, the sliding block 301 slides inside the sliding groove 202, and the sliding groove 202 guides the moving direction of the sliding block 301 to ensure the accuracy of the moving direction of the sliding block 301. The installation groove on the outside of the sliding block 301 guides the position of the wire during use to prevent the wire from shaking relative to the inside of the hook 201. The springs 302 cooperate with the sliding block 301 to control the position of the telescopic component 4, so that the telescopic component 4 cooperates with the moving component 3 to clamp the wire and prevent the wire from moving relative to the hook 201 during use.

[0033] As Figures 1 to 6As shown, the telescopic component 4 includes connecting blocks 401. There are multiple connecting blocks 401, and the connecting blocks 401 are arranged on the other side of the sliding block 301. Guide grooves 402 are provided on one side of the opposite faces of the connecting blocks 401. Telescopic blocks 405 are provided inside the guide grooves 402. Guide blocks 404 are provided on the outer sides of the telescopic blocks 405. Connecting grooves 403 are opened on the sides of the connecting blocks 401 relative to the guiding grooves 204. The guide blocks 404 slide inside the connecting grooves 403 and the guiding grooves 204. Pressing rollers 406 are provided on one side of the opposite faces of the telescopic blocks 405. Specifically, the connecting grooves 403 cooperate with the guide blocks 404 to guide the moving direction of the telescopic blocks 405 to ensure the accuracy of the direction when the telescopic blocks 405 move. At the same time, the guide blocks 404 cooperate with the guiding grooves 204 to control the position of the telescopic blocks 405 relative to the connecting blocks 401. The guide blocks 404 are adapted to the guide grooves 402, and the shape of the telescopic blocks 405 can be prismatic with four sides, prismatic with six sides, cylindrical, etc. During the process of hooking the hook 201 with the wire, first, the wire contacts the sliding block 301. During the contact process, the hook 201 is pulled downward by the telescopic ladder 1. While the hook 201 moves downward, the guide pushes the sliding block 301 to move relative to the hook 201. During the movement of the sliding block 301, the telescopic blocks 405 are driven to move towards each other through the cooperation of the guiding grooves 204, the guide blocks 404, and the connecting grooves 403. While the telescopic blocks 405 move towards each other, the wire is squeezed and fixed by the pressing rollers 406 to prevent the wire from moving relative to the hook 201 during the climbing process and ensure the stability of the connection between the hook 201 and the wire. When it is necessary to remove the hook 201, first, the hook 201 is pushed upward by the telescopic ladder 1. While the hook 201 moves upward, the sliding block 301 and the connecting block 401 move in the opposite direction relative to the hook 201 under the push of the spring 302. The sliding block 301 and the connecting block 401 moving in the opposite direction drive the telescopic blocks 405 and the pressing rollers 406 to move in the opposite direction through the cooperation of the guide blocks 404, the connecting grooves 403, and the guiding grooves 204, thereby releasing the limit on the wire and enabling the hook 201 to be separated from the wire.

[0034] As Figures 1 to 6 shown, a fixing pad 303 is provided inside the installation groove. A friction groove is opened inside the fixing pad 303. Specifically, when in use, the fixing pad 303 blocks the sliding block 301 and the wire to prevent the wire from directly contacting the fixing pad 303. The fixing pad 303 is made of rubber material. The rubber fixing pad 303 cooperates with the friction groove to further increase the friction with the wire during use and prevent the wire from moving relative to the hook 201.

[0035] As Figures 1 to 6As shown, the extrusion roller 406 is made of rubber. Specifically, when connecting with the wire, the extrusion roller 406 cooperates with the fixing pad 303 to fix the wire, avoiding the movement of the wire relative to the hook 201. The rubber extrusion roller 406 and the fixing pad 303 further increase the friction during connection, preventing the hook 201 from moving relative to the wire during use.
