[0019] Example 1: Reference Figure 1 - Figure 6 As shown, a wire and cable traction device of this embodiment includes a support frame 1, a traction mechanism is provided at the middle of the upper end of the support frame 1, and the traction mechanism includes a clamping assembly and a driving assembly; The clamping assembly includes a plurality of clamping claws 8, which are composed of two groups of semicircular claw fingers 81. An opening and closing cylinder 12 is provided at the middle of the bottom end of the clamping claw 8, and the opening and closing cylinder 12 is used to drive the two groups of claw fingers 81 to perform opening and closing movements; The driving assembly includes two groups of chains 4 rotating in parallel, and four groups of sprockets 5 are arranged on the inner sides of the two groups of chains 4. The four groups of sprockets 5 are used to drive the two groups of chains 4 to perform synchronous rotational motion, and the sprockets 5 are driven by a motor; multiple groups of connecting rods 6 are installed equidistantly between the two groups of chains 4, and the multiple groups of connecting rods 6 are driven by the two groups of chains 4 to perform circular rotational motion, and the clamping claws 8 are movably installed in the middle of the upper end of the connecting rods 6.

[0020] Among them, one set of sprockets 5 is driven to rotate by a motor, and under the transmission of the chain 4, the two sets of chains 4 and the four sets of sprockets 5 are synchronously rotated in a circular motion, thereby driving the multiple sets of clamping claws 8 to follow the circular rotation motion.

[0021] A fixing frame 13 is provided in the middle of the bottom end of the connecting rod 6, and the opening and closing cylinder 12 is installed in the middle of the inner side of the fixing frame 13. A movable plate 11 is installed at the output end of the opening and closing cylinder 12. The movable plate 11 is located in the middle of the bottom end of the connecting rod 6. Connecting shafts 10 are installed on both sides of the upper end of the movable plate 11. The connecting shaft 10 passes through the connecting rod 6 and is movably connected to the bottom of the claw finger 81 through the movable part 9; support columns 7 are provided on both sides of the upper end of the connecting rod 6, and two groups of claw fingers 81 are movably installed in the middle of the upper ends of the two groups of support columns 7 respectively.

[0022] Among them, the movable plate 11 can be driven to move up and down by the opening and closing cylinder 12. When the movable plate 11 rises, the connecting shaft 10 will be pushed upward, and then the bottom of the claw fingers 81 will be pushed through the movable part 9, so that the two groups of claw fingers 81 will be opened. Conversely, when the movable plate 11 moves downward, the connecting shaft 10 and the movable part 9 will be pulled downward, so that the bottom of the two groups of claw fingers 81 will be pulled downward, so that the two groups of claw fingers 81 will be rotated and closed, thereby clamping and fixing the cable.

[0023] In some examples, two groups of limiting rollers 2 are provided in the middle of the left end of the support frame 1, and the two groups of limiting rollers 2 are distributed in a vertical direction. A guide wheel 3 is provided on the upper side of the right end of the limiting roller 2, and the guide wheel 3 is movably installed on the upper side of the left end of the support frame 1. The two groups of limiting rollers 2 and the guide wheel 3 both guide the traction and conveying route of the cable, so that the cable must pass through the clamping claw 8, thereby providing convenience for the clamping claw 8 to clamp and pull the cable.

[0024] In some examples, a plurality of sets of moving wheels 20 are disposed at the bottom of the support frame 1 .

[0025] In some examples, a storage rack 21 is provided on the right side of the bottom end of the support frame 1, and a pull rod 22 is movably installed on the inner middle part of the storage rack 21. The pull rod 22 makes it convenient for workers to move and transport the traction device of the present invention, thereby improving the convenience during use. The storage rack 21 can store the pull rod 22, thereby improving the convenience during traction and transportation of the cable and avoiding obstruction of the transportation of the cable by the pull rod 22.

[0026] In some examples, the inner end of the claw finger 81 is provided with an anti-skid pad to play an anti-skid role. At the same time, it also plays a protective role in the clamping of the cable to prevent the claw finger 81 from scratching the outer sheath of the cable.

[0027] Example 2: Reference Figure 1 - Figure 6 As shown, based on Example 1, a wire and cable traction device also includes the following structure: A conveying assembly is provided at the right end of the traction mechanism, and the conveying assembly includes a traction belt 15. The traction belt 15 is connected to the sprocket 5 through a synchronous belt assembly 14. A plurality of movable wheels 16 are provided in the middle of the upper end of the traction belt 15. Under the transmission of the synchronous belt assembly 14, the conveying assembly and the driving assembly are driven by the same motor to improve the accuracy and stability of the synchronous operation.

[0028] A lifting frame 17 is provided in the middle of the upper end of the traction belt 15, and multiple sets of movable wheels 16 are movably installed in the middle of the bottom end of the lifting frame 17. Lifting cylinders 19 are provided on both sides of the upper end of the lifting frame 17. Two sets of lifting cylinders 19 are fixedly installed on the upper right side of the support frame 1. The two sets of lifting cylinders 19 are used to drive the lifting frame 17 to perform lifting movements. The lifting frame 17 is driven by the two sets of lifting cylinders 19 to perform lifting movements. When the lifting frame 17 drives the multiple sets of movable wheels 16 to rise, it is convenient for the staff to pass the cable through the conveying component for laying. When the lifting frame 17 drives the multiple sets of movable wheels 16 to descend, the cable can be pressed down, so that the cable fits tightly on the surface of the traction belt 15, so that the traction belt 15 can pull and convey the cable when it rotates.

[0029] In some examples, a limit plate 18 is arranged between the lifting cylinder 19 and the lifting frame 17. The limit plate 18 is fixedly installed on the upper right side of the support frame 1. The output end of the lifting cylinder 19 passes through the limit plate 18. The limit plate 18 plays the role of a limit guide to improve the stability of the lifting frame 17 in vertical lifting.

[0030] In some examples, the synchronous belt assembly 14 includes a synchronous belt and a synchronous wheel. The two sets of synchronous wheels are respectively installed on one set of sprockets 5 and the rotating shaft of the traction belt 15, and then the transmission connection is performed through the synchronous belt, so that when the driving assembly is running and rotating, the traction belt 15 can be synchronously driven to run and rotate.

[0031] The working principle of the present invention is: During use, the cable is first passed through the two sets of limit rollers 2, then passed around the guide wheel 3, and finally passed through the conveying assembly. At this time, the cable will pass through the chain 4; After the cable is laid, the two sets of lifting cylinders 19 are started to push the lifting frame 17, so that the lifting frame 17 drives the multiple sets of movable wheels 16 to descend, thereby pressing the cable on the traction belt 15 for transportation; Then the motor is started to drive the sprocket 5 to rotate. Under the transmission of the two sets of chains 4, the four sets of sprockets 5 and the two sets of chains 4 are rotated in a circular manner, thereby driving the clamping assembly to follow the rotational motion; When the clamping claw 8 rotates from the left end to the upper side, the two groups of claw fingers 81 of the clamping claw 8 are in an open state. As the clamping claw 8 moves, the two groups of claw fingers 81 in the open state move to the two sides of the cable. At this time, the opening and closing cylinder 12 is started, and the movable plate 11 is driven down, so that the two groups of connecting shafts 10 pull the two groups of claw fingers 81 through the movable member 9, so that the two groups of claw fingers 81 rotate and close, thereby clamping and fixing the cable; and when the clamping claw 8 moves to the right end corner position of the chain 4, the opening and closing cylinder 12 is used to push, and the two groups of claw fingers 81 are opened under the push of the movable plate 11, the connecting shaft 10 and the movable member 9, so as to release the clamping force on the cable, until it rotates to the upper end position of the chain 4 again to clamp the cable, forming a cycle of work; When the driving component is in operation, the traction belt 15 can be synchronously driven by the synchronous belt component 14, so that the traction belt 15 is in operation, thereby realizing traction and transportation of the cable.

[0032] In the present invention, after the multiple groups of clamping claws 8 clamp and fix the cable, driven by the rotation of the chain 4, the multiple groups of clamping claws 8 will generate pulling force on the cable, which can reduce the pressure of the traction belt 15 and improve the stability of the traction and transportation of the cable. In the process of clamping and pulling the cable, at least three groups of clamping claws 8 clamp and fix the cable each time, which plays a role in dispersing the pressure and ensuring the stability of the pulling force on the cable. Furthermore, under the action of the synchronous belt assembly 14, the conveying assembly and the driving assembly are both driven by the same motor, thereby effectively improving the accuracy and stability of the synchronous operation of the clamping assembly and the conveying assembly.
