Description

Technical Field

[0001] The utility model relates to the technical field of cable construction, in particular to a wire and cable laying support device for electric power construction. Background Technique

[0002] During the process of electric power construction, it is necessary to tow and lay cables, and usually the cables need to pass through pipelines buried underground. Cable wells are opened in cooperation with the underground pipelines. Cable wells are used for long-distance underground power supply, line installation, cable maintenance and other operations, which effectively facilitate the construction and maintenance of cables. Due to the large self-weight of the cables, after the cables enter the pipelines, they are prone to the phenomenon of sagging and bending, which affects the towing of the cables. Moreover, the cables need to pass through the pipeline openings under the cable wells, and the bent cables will rub against the edges of the pipeline openings, resulting in abrasion of the cable sheaths, affecting the use of the cables and the subsequent towing operations. Therefore, a cable laying support device is needed for support and guidance.

[0003] However, the existing wire and cable laying support devices have certain defects in actual use. Although they can support, lift and guide the cables during the construction process, they cannot limit the cables well during the pulling process, easily causing the cables to fall off the support devices, thus losing the towing effect and affecting the construction progress. At the same time, it may also damage the cable surface. Content of the Utility Model

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model: A wire and cable laying support device for electric power construction includes a base 1 for placing the cable support device during construction, the bottom end of which is welded with legs 2 of the support assembly, and the bottom end of the legs 2 can be welded with fixed support feet 3 to ensure stability during construction use. In order to conveniently adapt to different heights, a lifting device (such as an electric push rod, etc., a relatively mature technology, not described in detail here) can be provided between the legs 2 and the base 1 to facilitate lifting and guiding during the laying of wires and cables. The middle part of the top end of the base 1 is welded with a mounting plate 4, and the mounting plate 4 is connected with a rotating plate 5 through a rotating mechanism, which can be conveniently rotated along with the laying traction, flexibly adjusted, and more convenient for traction.

[0023] Please refer to Figures 1-5, in order to facilitate limiting during the cable guiding process, prevent the cable from falling off the guiding component, and not affect the cable laying work, a rectangular plate 6 is welded to the top of the rotating plate 5. An adjustment groove 15 (with a T-shaped cross-section) of the adjustment mechanism is provided in the middle of the top of the rectangular plate 6. Two groups of adjustment blocks 17 are symmetrically and slidably arranged inside it. A connecting member 7 of the guiding component is bonded to the top of the adjustment block 17. An arc-shaped positioning plate 8 is bonded to the connecting member 7 (the two arc-shaped positioning plates 8 can be spliced into a three-quarter ring or a ring with other proportions, which can ensure cable limiting and prevent falling off while not affecting the guiding). Guide balls 9 are equidistantly and rotatably arranged on the inner arc surface of the arc-shaped positioning plate 8, which can reduce the friction with the cable and facilitate the guiding. In order to facilitate adjusting the position between the two arc-shaped positioning plates 8 and fixing them after adjustment, threaded holes 20 of the positioning component are symmetrically provided on both side walls of the adjustment block 17. A fastening bolt 18 is engaged with the threaded hole 20 by threads. An empty groove 16 is provided on the rectangular plate 6 to facilitate the movement of the fastening bolt 18 along with the adjustment block 17. In order to ensure the fastening effect, a gasket 19 is sleeved on the fastening bolt 18 to ensure the fastening effect with the rectangular plate 6.

[0024] Please refer to Figures 1-5 , in order to facilitate rotational adjustment according to the traction force, better guide, and facilitate the laying work, a bearing 11 of the rotating mechanism is installed in the middle of the mounting plate 4. The inner ring of the bearing 11 is fixedly installed with a rotating rod 14, and the rotating rod 14 is welded and fixed to the rotating plate 5, which can facilitate the rotation of the rotating plate 5 and the rotating rod 14 on the mounting plate 4. In order to ensure stability during the rotation process, support columns 12 are welded equidistantly under the rotating plate 5, and the number of them can be four groups. Rotating balls 13 are arranged at the bottom ends, and an annular sliding groove 10 for facilitating the rolling of the rotating balls 13 is provided on the mounting plate 4, which can facilitate the rotational guiding and provide support to ensure stability.

[0025] Working principle: When the utility model is in use, the whole device is placed at the construction lifting and traction place. By placing the wire and cable between the two arc-shaped positioning plates 8, and pushing the two connecting pieces 7, the adjusting blocks 17 slide close to each other in the adjusting grooves 15. At this time, the guiding balls 9 are in contact with the wire and cable, which can facilitate the guiding during subsequent traction. At the same time, the two arc-shaped positioning plates 8 can limit the wire and cable to prevent it from falling off. Rotate the fastening bolt 18 clockwise, cooperate with the threaded hole 20 and the gasket 19, and can be fastened to the rectangular plate 6, thereby preventing the adjusting block 17 from sliding and ensuring the effect of guiding and traction. During the traction process, when the direction of the cable changes, at this time, a rotational pulling force is generated on the arc-shaped positioning plate 8, so that the rotating plate 5 and the rotating rod 14 rotate on the bearing 11. At the same time, the rotating ball 13 under the support column 12 rotates in the annular sliding groove 10 to ensure the stability of the rotation. Thus, it can rotate and change along with the traction direction of the cable, making the traction operation more convenient, relatively labor-saving, and reducing the wear of the cable.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
