Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a cable laying device for electrical engineering automation equipment. Background Technology

[0002] As is well known, cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Depending on the application, it can be divided into several laying methods such as overhead, underground pipeline and direct burial, underwater, wall and tunnel. The rational selection of cable laying method is very important to ensure the transmission quality, reliability and construction and maintenance of the line.

[0003] When installing cables underground, they need to be transported into protective conduits. Because cables are easily bent and the space inside the conduit is limited, a traction machine is typically used. The conduit openings are usually quite rough, causing friction between the cable and the conduit opening during cable transport, resulting in significant resistance and making construction difficult. In particular, the outer layer of the cable is easily scratched by the conduit opening, severely impacting its future use. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable laying device for electrical engineering automation equipment, comprising a sleeve, the sleeve being installed at the end of a protective tube for protecting the cable, connecting members being arranged opposite to each other on both sides of the sleeve, each connecting member being threadedly connected to a lead screw, and a mounting bracket being rotatably connected to the opposite side of the two lead screws, and a roller being rotatably connected inside each mounting bracket, the cable passing through the space between the rollers on both sides, the rollers preventing the cable from contacting the end of the protective tube.

[0008] Furthermore, the sleeve is threaded with at least one set screw to accommodate protective tubes of different diameters. The screw-in end of the set screw can abut against the outer wall of the protective tube, and tightening the set screw will fix the sleeve onto the protective tube.

[0009] Furthermore, the mounting bracket is provided with a sliding rod, which is slidably connected to the connector.

[0010] Furthermore, the diameter of the roller gradually decreases from both sides towards the center.

[0011] Furthermore, a protective sleeve is installed on the outer wall of the roller.

[0012] Furthermore, the lead screw is provided with a screwing component for rotating the lead screw.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a cable laying device for electrical engineering automation equipment, which has the following advantages:

[0015] This cable laying device for electrical engineering automation equipment, through the arrangement of sleeves, connectors, lead screws, mounting brackets, and rollers, allows the cable to pass between the rollers on both sides. The rollers prevent the ends of the cable from contacting the protective tube. Rotating the lead screw matches the distance between the two rollers with the diameter of the cable. During the cable threading process, the rollers guide the cable, and the rollers rotate as the cable passes through, reducing friction on the cable. During the cable laying process, it can effectively prevent the cable from being scratched by the ends of the protective tube, thus protecting the cable. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4This utility model discloses a cable laying device for electrical engineering automation equipment, comprising a sleeve 1, which is installed at the end of a protective tube 9. A cable 6 is inserted into the protective tube 9, which protects the cable 6. Several set screws 8 are threaded onto the sleeve 1. Rotating the set screws 8 allows for adaptation to protective tubes 9 of different diameters. The screw-in end of the set screw 8 abuts against the outer wall of the protective tube 9. Tightening the set screws 8 fixes the sleeve 1 onto the protective tube 9. Connecting parts 2 are arranged opposite each other on both sides of the sleeve 1. Each connecting part 2 is threaded onto a lead screw 3, which is equipped with... A screw 10 is provided for rotating the lead screw 3. The two lead screws 3 are rotatably connected to the mounting bracket 4 on opposite sides. Each mounting bracket 4 is rotatably connected to a roller 5. Rotating the lead screw 3 can adjust the distance between the rollers 5 on both sides, which can accommodate cables 6 of different diameters. The cable 6 passes through the rollers 5 on both sides. The rollers 5 prevent the cable 6 from contacting the end of the protective tube 9. When the cable 6 passes through the rollers 5, the rollers 5 will rotate, reducing friction on the cable 6. During the cable 6 laying process, it can effectively prevent the cable 6 from being scratched by the end of the protective tube 9.
