Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of devices for power transmission project construction, specifically a cable laying and traction device for power transmission project construction. Background Technology
[0002] Cable laying traction devices are mainly used in power engineering construction for cable laying. Their primary function is to provide traction force, replacing manual cable dragging, especially in scenarios involving long-distance, heavy-weight cable laying. A dual-traction belt scheme is a commonly used technical solution, such as the clamp-type cable pulling machine disclosed in patent CN217626811U. To increase the friction between the traction belt and the cable, the traction belt often adopts a multi-piece structure, as shown in the attached diagram. Figure 1 As shown, multiple conveyor belt modules are placed on the conveyor belt. This structure allows for the use of relatively thick conveyor belt modules with a certain degree of deformation capability. However, the multiple-block structure makes it easy for debris such as mud, sand, and leaves to accumulate in the gaps between the blocks. If not cleaned, this can easily lead to problems such as equipment jamming, affecting work efficiency. Summary of the Invention

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] As attached Figure 2-5 As shown, the cable laying traction device for power transmission project construction involved in this utility model includes a base 1, two traction belt units 2 arranged opposite to each other, and a spacing adjustment unit 3.
[0020] As attached Figure 2 , 3 As shown, the spacing adjustment unit 3 includes a central lead screw 31 and several supporting slide rods 32. The central lead screw 31 and several supporting slide rods 32 are mounted on the base 1. A rotating handle 311 is provided on one side of the central lead screw 31.
[0021] The base 1 is U-shaped, with the central lead screw 31 and several supporting slide rods 32 located on opposite side walls of the base 1 at both ends.
[0022] The traction belt unit 2 includes a base plate 21, a traction belt 22, a drive motor 23, a traction pulley 24, an extrusion component 25, a support column 26, a tensioning structure 27, and a top plate 28.
[0023] Two traction belt units 2 are arranged horizontally and parallel to each other. The lower part of the base plate 21 is provided with a through hole 211 for the support slide rod 32 to pass through and a threaded through hole 212 for the central lead screw 31 to pass through. By rotating the rotating handle 311 of the central lead screw 31, the two base plates 21 can be driven to move relative to each other, thereby realizing the adjustment of the distance between the two traction belt units 2.
[0024] The top plate 28 is connected to the bottom plate 21 by several supporting columns 26. Two traction pulleys 24 are arranged on both sides of the space between the bottom plate 21 and the top plate 28. The upper and lower ends of the traction pulleys 24 are rotatably connected to the top plate 28 and the bottom plate 21, respectively. One of the traction pulleys 24 is connected to the drive motor 23. Specifically, the drive motor 23 is set on the bottom plate 21, and its output torque is reduced by a reduction gearbox 231 and rotated 90 degrees to drive the traction pulley 24 to rotate.
[0025] The traction belt 22 is fitted on the outside of the two traction pulleys 24.
[0026] As attached Figure 2 , 4As shown, the traction pulley 24 on the other side is connected to the base plate 21 and the top plate 28 via a tensioning structure 27. The tensioning structure 27 includes a fixing rod 271, an adjusting screw 272, and a slider 273. A sliding groove z1 is provided in the center of one side of the base plate 21 and the top plate 28. The slider 273 has an I-shaped cross-section and is located at the sliding groove z1. The traction pulley 24 is rotatably connected to the slider 273, specifically through a bearing. A vertical connecting plate z2 is provided on the slider 273. The fixing rod 271 is located on the bottom surface of the base plate 21 and the top surface of the top plate 28 inside the sliding groove z1. The adjusting screw 272 is horizontally arranged, with one side fixed to the fixing rod 271 and the other end passing through a through hole in the vertical connecting plate z2. Adjusting nuts z3 are provided on the adjusting screws 272 on both sides of the vertical connecting plate z2. By adjusting the position of the slider 273, the tension of the traction belt can be achieved, and the position of the slider 273 can be fixed by adjusting the nuts z3.
[0027] As attached Figure 2 , 3 As shown, the extrusion component 25 is arranged vertically between the bottom plate 21 and the top plate 28, located on the inner side, and closely attached to the traction belt 22.
[0028] The extrusion member 25 includes an extrusion member shaft 251 and a rotating extrusion member 252. The extrusion member shaft 251 is fixed or rotatably mounted on the bottom plate 21 and the top plate 28 at both ends. The rotating extrusion member 252 is located outside the extrusion member shaft 251 and has a through hole in its center for the extrusion member shaft 251 to pass through. The rotating extrusion member 252 is a soft material rod, such as a rubber rod or a silicone rod, and has a groove on its outer side.
[0029] Appendix Figure 2 One of the traction belt units 2 is provided with two extrusion members 25, and there can be three or more.
[0030] Several sliding rods 11 are provided between the side walls of the base 1. The two ends of the sliding rods are rotatably connected to the side walls of the base 1 through bearings. The sliding rods 11 are located in the gap between the bottom plate 21 and the lower end of the traction belt 22.
[0031] In use, adjust the distance between the traction belt units 2, place the cable between the traction belts 22, and the slide bar 11 supports the cable at the bottom. Then, adjust the distance between the traction belt units 2 through the spacing adjustment unit 3 to clamp the cable. Then, start the drive motor 23. The friction between the traction belt and the cable drives the cable to move, thereby pulling the cable. The squeezing member 25 can increase the friction between the traction belt and the cable and increase the clamping force on the cable.
[0032] Meanwhile, since the rotating extruder 252 can rotate relative to the extruder shaft 251, its friction on the traction belt can be reduced, thus preventing the traction belt from wearing out quickly.
[0033] As attached Figure 2 , 5 As shown, to facilitate the insertion of cables, guide slides 29 are provided on the opposite side of the top plate 28. The upper part of the guide slides 29 is bent outward to guide the cables.
[0034] It should be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
