Description

Technical Field

[0001] The utility model belongs to the field of electric power engineering, and in particular relates to a cable traction device for electric power engineering construction. Background Art

[0002] Cable pulling refers to the process of pulling cables to designated locations using specialized equipment during cable laying. This process typically requires consideration of cable weight, length, and the laying environment to ensure safety and efficiency. Cable pulling devices are mechanical devices used to perform this operation. With powerful pulling force and a flexible control system, they can significantly improve laying efficiency, reduce labor costs, and ensure cable safety during installation.

[0003] When pulling cables, cable pulling devices usually use multiple movable rollers to assist in movement. However, cables are usually wound on cable reels and usually have a certain degree of curvature. Existing cable pulling devices usually do not have the function of straightening. The bent cable will affect the speed and stability of cable transmission. At the same time, compared with straight cables, bent cables consume longer lengths at the same distance, resulting in waste of cable materials. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] like Figures 1 to 4As shown, a cable traction device for power engineering construction provided by an embodiment of the present invention includes a mounting base 1, a traction assembly 2 and a limit assembly 3. The mounting base 1 includes a base 11 and an installation box 12. The installation box 12 is arranged at the upper end of the base 11. The installation box 12 and the base 11 are integrally formed.

The driven shaft 25 is arranged above the driving shaft 22. A driving gear 23 is installed on the outside of the driving shaft 22, and a driven gear 24 is installed on one side of the driven shaft 25. The driven gear 24 and the driving gear 23 are meshed with each other. A traction roller 26 is fixedly installed on the outside of the driving shaft 22 and the driven shaft 25. The straightening roller 28 is fixedly installed on the outside of the auxiliary shaft 27. The limit assembly 3 includes a limit motor 31, a bidirectional screw rod 32 and a splint 34. The limit motor 31 is installed on the outside of the installation box 12. The main shaft of the limit motor 31 is fixedly connected to the bidirectional screw rod 32. A light rod 33 is provided under the bidirectional screw rod 32, and the splint 34 is sleeved on the outside of the bidirectional screw rod 32 and the light rod 33.

[0025] In one embodiment of the present invention, during use, the cable is clamped between the two traction rollers 26, and the driving shaft 22 can be driven to rotate by the rotation of the traction motor 21. Under the meshing action of the driving gear 23 and the driven gear 24, the driven shaft 25 and the driving shaft 22 are driven to rotate in the same direction, thereby pulling the cable. The multiple auxiliary shafts 27 and straightening rollers 28 are provided to squeeze and straighten the cable, thereby eliminating the mechanical stress generated during the cable production and laying process. The bidirectional screw rod 32 is driven to rotate by the provided limiting motor 31, and the cable is clamped by the provided clamping plate 34, so that the cable can be fixed when it is not needed to be pulled.

[0026] like Figure 2 and Figure 3 As shown, as another embodiment of the present invention, one end of the driving shaft 22 and the driven shaft 25 is movably located on the inner wall of the installation box 12, and the other end of the driving shaft 22 and the driven shaft 25 is movably passed through the side wall of the installation box 12.

[0028] In one embodiment of the present invention, an auxiliary shaft 27 is movably installed on the inner wall of the installation box 12.

[0029] like Figure 2 As shown, as another embodiment of the present invention, a first cable groove 261 is fixedly opened on the outer side of the traction roller 26, and a second cable groove 281 is fixedly opened on the outer side of the straightening roller 28.

The ventilation of multiple auxiliary shafts 27 and straightening rollers 28 is arranged alternately and perpendicularly to each other, thereby further improving the straightening effect of the cable.

[0031] like Figure 3 and Figure 4 As shown, as another embodiment of the present invention, two sections of threads in opposite directions are provided on the outer side of the bidirectional screw rod 32, one end of the bidirectional screw rod 32 is movably located on the inner wall of the installation box 12, and the other end of the bidirectional screw rod 32 passes through the side wall of the installation box 12, and the two ends of the light rod 33 are fixedly connected to the inner wall of the installation box 12.

[0032] Specifically, the two clamping plates 34 are provided with threaded holes in opposite directions corresponding to the outer threads of the bidirectional screw rod 32 , and the clamping plates 34 are provided with a circular through hole with an aperture matching that of the polished rod 33 corresponding to the polished rod 33 .

[0033] In one embodiment of the present invention, a limiting motor 31 is provided to drive the bidirectional screw rod 32 to drive the movement of the clamping plate 34, and cooperates with the optical rod 33 to limit the clamping plate 34, so that the clamping plate 34 can and can only move along the axial direction of the optical rod 33 and the bidirectional screw rod 32, thereby clamping the cable.

[0034] like Figure 4 As shown, as another embodiment of the present invention, rubber pads 35 are fixedly provided on the inner sides of the two clamping plates 34. The rubber pads 35 are made of elastic material, and arc-shaped grooves are fixedly provided on the sides of the rubber pads 35 corresponding to the cables.

[0035] In one embodiment of the present invention, the rubber pad 35 is provided to play a protective role and prevent the cable from being squeezed and deformed by the clamping plate 34. The rubber pad 35 can be made of rubber, silicone or other materials. The arc-shaped groove opened on the side of the rubber pad 35 further improves the clamping effect of the cable.
