[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] First embodiment

[0026] As attached Figure 1 , Attachment Figure 2 and attached Figure 3 Shown: A tensioning device for cable drawing, comprising a mounting plate 1 and a set of support wheels 2 rotatably connected to the front face of the mounting plate 1. The support wheels 2 can support the cable, facilitating subsequent tensioning thereof.

[0027] The tensioning assembly 3 is arranged below the mounting plate 1, and includes a hanging plate 301 arranged below the mounting plate 1 and a buffer structure arranged on the hanging plate 301. The buffer structure of the tensioning assembly 3 includes two slide bars 302 slidably connected to the hanging plate 301, and the bottom ends of the two slide bars 302 are fixedly connected to a fixed plate 303. The front of the fixed plate 303 is rotatably connected to a tensioning wheel 304. The outer surface of each slide bar 302 is sleeved with a spring 305. The tensioning wheel 304 can support the cable and can cooperate with the support wheel 2 to tension the cable. When the cable is tensioned, the tensioning wheel 304 will drive the fixed plate 303 to rise and squeeze the spring 305. When the spring 305 contracts, it will buffer the tensioning force on the cable, thereby avoiding breakage of the metal conductor or insulation layer inside the cable.

[0028] The top ends of the two slide bars 302 are fixedly connected with a baffle 306 , which is located above the hanging plate 301 . The baffle 306 can be used to connect the slide bars 302 and the hanging plate 301 to prevent the slide bars 302 and the hanging plate 301 from separating.

[0029] Second embodiment

[0030] As attached Figure 1 and attached Figure 4 As shown: the adjustment component 4 is arranged below the mounting plate 1 and is movably connected to the buffer tensioning component 3, and is used to adjust the height of the tensioning component 3. The adjustment component 4 includes a support plate 401 arranged below the mounting plate 1, and the upper surface of the support plate 401 is rotatably connected to two threaded rods 402. The top of each threaded rod 402 passes through the hanging plate 301 and is rotatably connected to the bottom surface of the mounting plate 1, and the threaded rod 402 is threadedly connected to the hanging plate 301. By rotating the threaded rod 402, the hanging plate 301 will drive the tensioning wheel 304 to move, and the tensioning wheel 304 will drive the cable to move, thereby achieving tensioning of the cable.

[0031] The outer surface of each threaded rod 402 is fixedly connected to a worm wheel 403, and the outside of the two worm wheels 403 are jointly meshed with a worm 404. The left and right ends of the worm 404 are rotatably connected to support blocks 405. The bottom surface of each support block 405 is connected to the upper surface of the support plate 401. The support blocks 405 can be used to stabilize the worm 404, allowing the worm 404 to be stably meshed with the worm wheel 403. When the worm 404 is rotated, the two worm wheels 403 will synchronously drive the two threaded rods 402 to rotate in the same direction, making it more convenient for staff to operate.

[0032] Two retaining rings 406 are fixedly connected to the outer surface of each threaded rod 402. The two sets of retaining rings 406 are respectively located above and below the hanging plate 301. The set retaining rings 406 can limit the lifting and lowering of the hanging plate 301 to prevent the tensioning wheel 304 from colliding and failing to achieve the buffering effect.

[0033] Two inclined support plates 407 are fixedly connected to the upper surface of the support plate 401, and the top of each inclined support plate 407 is connected to the bottom surface of the mounting plate 1. The inclined support plates 407 can be used to connect the mounting plate 1 and the support plate 401, thereby achieving a reinforcement effect on the mounting plate 1.

[0034] Third embodiment

[0035] As attached Figure 1 and attached Figure 2As shown: A group of guide wheels 5 are provided on the side where the two support wheels 2 are away from each other, and the back of each guide wheel 5 is rotatably connected to the front of the mounting plate 1. The provided guide wheels 5 can be used to guide the cables and effectively prevent the cables from falling off.

[0036] Working principle: When in use, the cable is put on the supporting wheel 2 and the tensioning wheel 304, and then the worm 404 is rotated. The worm wheel 403 will drive the threaded rod 402 to rotate on the hanging plate 301, and the hanging plate 301 will drop. At the same time, the tensioning wheel 304 will drive the cable to drop. When the cable drops and is in a tensioned state, the cable will exert a reaction force on the tensioning wheel 304, and the tensioning wheel 304 will drive the fixed plate 303 to rise. The fixed plate 303 will compress the spring 305. When the spring 305 contracts, it will absorb part of the tensioning force of the cable, thereby buffering the force when the cable is tensioned, and effectively avoiding breakage of the metal conductor or insulation layer inside the cable.
