Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and more specifically, to a cable traction mechanism. Background Technology

[0002] Cable traction mechanisms are widely used in the transportation, installation, and maintenance of cables, such as in power engineering, construction sites, and urban lighting. They effectively improve the efficiency and accuracy of cable installation, reduce the labor intensity of workers, and are an important tool for cable construction and maintenance.

[0003] Patent CN220596606U discloses a wire and cable pulling mechanism. This mechanism involves placing multiple sets of wire rollers inside a pulling frame, which are then fixed in place by mounting components. The wire is then passed through the lead-in holes on a horizontal plate and the lead-in wheels at the bottom. By gripping the handle and rotating the ball screw, each set of clamping frames moves relative to the other, causing the lead-in wheels on both sides of the wire to clamp it, thus pulling multiple sets of wires. However, while this wire and cable pulling mechanism can simultaneously install multiple sets of wire rollers, it can only accommodate multiple sets of wire rollers of the same length. It cannot be used to install and pull wire rollers of different lengths. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model aims to provide a wire and cable traction mechanism.

[0005] A wire and cable pulling mechanism includes a base on which a plurality of mounting units are movably connected; two adjacent mounting units are used to mount wire rollers.

[0006] The base includes a platform and two symmetrically arranged support legs fixed to the bottom of the platform; the platform has a first sliding groove; each support leg has a second sliding groove; the bottom of each mounting unit extends into the first sliding groove and is positioned at the second sliding groove by a limiting rod.

[0007] Furthermore, the platform of the base is a horizontally arranged flat plate structure, and the platform has two mutually symmetrical first sliding grooves.

[0008] Furthermore, each of the legs is a flat plate structure, and the legs are perpendicular to the platform.

[0009] Furthermore, each of the legs has multiple first connecting lugs attached to the bottom of its outer side, which are fixed to the ground using anchor rods or bolts.

[0010] Furthermore, the erection unit includes an erection plate, support plates located on both sides of the erection plate, and a second connecting lug located below the two support plates;

[0011] The mounting plate is a vertically arranged plate structure with mounting holes for mounting the wire rollers;

[0012] The two second connecting ears, the two support plates, and the mounting plate are an integral structure; the two second connecting ears are respectively embedded in the two first sliding grooves and can move along the first sliding grooves.

[0013] Furthermore, the mounting holes are provided in two locations, and the heights of the rollers mounted in the two adjacent mounting units are different;

[0014] The left and right sides of the non-end mounting unit can be used to mount wire rollers.

[0015] Furthermore, the support plate is a plate-like structure that is narrower at the top and wider at the bottom, and the span of the bottom surface of the support plate is greater than the width of the first groove.

[0016] Furthermore, the second connecting ear extends into the first sliding groove, and the connecting hole in the second connecting ear is flush with the second sliding groove for passing through the limiting rod.

[0017] Furthermore, the limiting rod is a screw rod, which passes through one of the support plates, one of the second connecting ears, another of the second connecting ears, and another of the support plates in sequence, and is then tightened with a nut, thereby achieving the positioning and fastening of the erection unit.

[0018] Furthermore, an auxiliary locking element is also provided in the first sliding groove between the two erection units for auxiliary positioning of the erection unit;

[0019] The auxiliary clip has a T-shaped longitudinal section and includes a horizontal clip and a vertical clip. The vertical clip is embedded in the first slide groove, and the lower end face of the horizontal clip abuts against the platform at the top of the first slide groove.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This wire and cable pulling mechanism has a first sliding groove on the base, and each erection unit can be movably connected to the base, thereby forming multiple erection units with different spacing. Therefore, it can be used to erect wire rollers of different lengths and specifications, and has a wide range of applications. Furthermore, there is a gap between the cables extending from two adjacent wire rollers, so that they will not interfere with each other.

[0022] Furthermore, limiting rods are sequentially passed through one plate, one second connecting lug, another second connecting lug, and another plate, and then tightened with nuts to achieve positioning and fastening of the erection unit. After the positions of two adjacent erection units are fixed, auxiliary clips are respectively inserted into the first sliding groove and next to the second connecting lug, with the side of the auxiliary clip abutting against the second connecting lug, which can assist in positioning the erection unit.

[0023] Furthermore, the bottom of the base is also connected to multiple first connecting ears, and the base is fixed to the ground by anchor rods, bolts or other fixing rods that can be fixed, to ensure the stability of the mechanism during the pulling of electric wires and cables.

[0034] 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.

[0035] like Figures 1-4 As shown, this embodiment provides a wire and cable traction mechanism, including a base 1, on which a plurality of mounting units 2 are movably connected, and two adjacent mounting units 2 are used to mount wire rollers.

[0036] In this embodiment, as Figure 2 , Figure 3 As shown, the base 1 includes a platform 11 and two symmetrically arranged support legs 12 fixed below the platform 11. A first sliding groove 13 is provided on the platform. Specifically, the platform 11 of the base 1 is a horizontally arranged flat plate structure, and two mutually symmetrical first sliding grooves 13 are provided on the platform 11. Each support leg 12 is a flat plate structure, and the support leg 12 is perpendicular to the platform 11. Each support leg 12 is provided with a second sliding groove 14. The bottom of each mounting unit 2 extends into the first sliding groove 13 and is positioned at the second sliding groove 14 by a limiting rod 3.

[0037] More specifically, each support leg 12 has multiple first connecting ears 15 connected to its outer bottom surface. Anchor rods, bolts, or other fixing rods are used to secure the base 1 to the ground, ensuring the stability of the mechanism during cable pulling. To further improve the stability of the base 1 during cable pulling, several support columns 16 are fixed to the lower end of the platform 11 in the base 1. These support columns 16 and the two support legs 12 simultaneously support the platform 11, ensuring the overall stability of the base 1.

[0038] In this embodiment, as Figure 2 , Figure 4 As shown, the mounting unit 2 includes a mounting plate 21, support plates 22 located on both sides of the mounting plate 21, and second connecting ears 23 located below the two support plates 22. The two second connecting ears 23, the two support plates 22, and the mounting plate 21 are an integral structure. The mounting plate 21 is a vertically arranged plate structure with mounting holes 211 for mounting the wire roller. The two second connecting ears 23 are respectively embedded in two first sliding grooves 13 and can move along the first sliding grooves 13. When the distance between the two mounting plates 21 matches the size of the wire roller to be mounted, a limiting rod 3 is used to position the mounting unit 2.

[0039] Furthermore, the mounting plate 21 has two mounting holes 211. In two adjacent mounting units, the mounting hole at the lower position and the mounting hole at the higher position can mount two different sets of wire rollers, meaning that the height of the wire rollers mounted in the two adjacent mounting units is different. Moreover, the two mounting holes 211 ensure that the mounting of wire rollers in the two adjacent mounting units does not interfere with each other, and there is a gap between the cables extending from the two adjacent wire rollers to prevent mutual interference. In other words, wire rollers can be mounted on the left and right sides of the non-end mounting unit.

[0040] Furthermore, the support plate 22 is a plate-like structure that is narrower at the top and wider at the bottom. The span of the bottom surface of the support plate 22 is greater than the width of the first slide groove 13, meaning that the support plate 22 will not fall off the first slide groove 13. The second connecting ear 23 extends into the first slide groove 13, and the connecting hole in the second connecting ear 23 is flush with the second slide groove 14 for passing through the limiting rod 3.

[0041] The limiting rod 3 is a screw, which passes sequentially through a plate 22, a second connecting ear 23, another second connecting ear 23, and another plate 22, and is then tightened with a nut to position and secure the mounting unit 2. When assuming the cable, first fix the mounting unit 2 at the leftmost end to the base 1, insert one end of the roller shaft into the mounting hole 211 of the mounting unit 2, and then move the adjacent mounting unit so that the mounting hole 211 of the adjacent mounting unit is passed through by the other end of the roller shaft. At this point, fix the adjacent mounting unit 2. When assuming the second roller, extend one end of the second roller shaft into the other mounting hole 211 of the second fixed-position mounting unit, then move the third mounting unit so that the mounting hole of the third mounting unit is passed through the other end of the second roller shaft. Then fix the position of the third mounting unit, and so on.

[0042] In this embodiment, an auxiliary locking member 4 is also provided in the first sliding groove 13 between the two mounting units 2. After the positions of the two adjacent mounting units 2 are fixed, the auxiliary locking member 4 is respectively inserted into the first sliding groove 13 and next to the second connecting ear 23, and the side of the auxiliary locking member 4 abuts against the second connecting ear 23, which can assist in the positioning of the mounting unit 2. Specifically, as follows Figure 1 and Figure 5 As shown, the longitudinal section of the auxiliary clip 4 is T-shaped, including a horizontal clip 41 and a vertical clip 42. The vertical clip 42 is embedded in the first slide groove 13, and the lower end face of the horizontal clip 41 abuts against the table surface at the top of the first slide groove.

[0043] The wire and cable traction mechanism provided in this embodiment has a first sliding groove 13 arranged on the base 1. Each mounting unit 2 can be movably connected to the base, thereby forming multiple mounting units with different spacings. This enables the mounting of wire rollers of different lengths and specifications in an adaptable manner, and has a wide range of applications.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
