Description

Technical Field

[0001] This utility model relates to the field of cable straightening technology, specifically to a cable straightening device for overhead conductors. Background Technology

[0002] During the production of overhead conductors, the aluminum alloy monofilaments within the conductors need to be inspected to ensure their performance and quality. Because overhead conductors undergo bending, folding, and coiling during installation, the finished product exhibits a spiral-shaped coiled state. Therefore, straightening is required during cable installation. Conventional cable straightening devices lack heating capabilities, and cables become hard and brittle at low temperatures, easily damaging the cable sheath during straightening and shortening its lifespan. Utility Model Content

[0003] The purpose of this utility model is to provide a cable straightening device for overhead conductors, which solves the problem that conventional cable straightening devices do not have a heating function, and the cables become hard and brittle at low temperatures, which can easily damage the cable sheath during straightening and shorten the cable's service life.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A cable straightening device for overhead conductors includes a frame. A horizontal plate is provided at the top of the frame. A dust removal component and a cable heating component are arranged sequentially from left to right along the horizontal plate. Roller cable straightening components are provided between the dust removal component and the cable heating component, and at the right end of the cable heating component. A driving component is provided at the lower end of the frame to drive the two roller cable straightening components to rotate. The cable heating component includes a horizontally arranged cylinder. Arc-shaped connecting sleeves are fitted at both ends of the cylinder. Connecting plates are provided at both ends of the arc-shaped connecting sleeves. Two spaced-apart support columns are provided at the lower end of each arc-shaped connecting sleeve. Four connecting plates are connected to the four support columns by bolts. A heating channel is provided inside the cylinder. A thermally conductive insulating ring is provided inside the heating channel. A spirally arranged heating rod is provided between the thermally conductive insulating ring and the inner wall of the heating channel. A touch screen is provided on the outer side of the cylinder. A temperature controller connected in series with the heating rod is built into the touch screen.

[0005] A further technical solution is that the dust removal assembly includes a first vertical plate, the top of which is provided with an extrusion plate. The right end of the extrusion plate is hinged to the right end of the first vertical plate. A first groove and a second groove are respectively provided on the left ends of the first vertical plate and the extrusion plate. A rotating shaft is provided in the first groove. A connecting shaft is rotatably sleeved on the rotating shaft. The upper end of the connecting shaft passes through the first groove and the second groove in sequence and is threaded with a nut. A first roller is rotatably provided on the front side of both the first vertical plate and the extrusion plate, and an anti-slip cotton cloth is sleeved on the first roller.

[0006] A further technical solution is that the roller cable straightening assembly includes a second vertical plate, on which a first rotating shaft and a second rotating shaft are rotatably arranged at vertical intervals. A second roller is fitted onto one end of each of the first and second rotating shafts on the front side of the second vertical plate. Each of the two second rollers has an arc-shaped groove arranged in a ring. A first geared disc and a second geared disc meshing with the first geared disc are respectively connected to one end of each of the first and second rotating shafts on the rear side of the second vertical plate. A first narrow V-belt pulley is also provided on the second rotating shaft. A motor is provided at the bottom of the horizontal plate, and a second narrow V-belt pulley is provided at the output end of the motor. A mounting plate is provided on the horizontal plate, and two third narrow V-belt pulleys are rotatably arranged on the mounting plate. The second narrow V-belt pulleys, the two first narrow V-belt pulleys, and the two third narrow V-belt pulleys are all connected by belt drive.

[0007] A further technical solution is that the mounting plate is provided with an opening slot for the belt to pass through.

[0008] Compared with the prior art, the beneficial effects of this utility model are: 1. By installing roller cable straightening components at both ends of the cable heating assembly, the cable is pre-straightened before being heated by the cable heating assembly. After heating, the cable is then straightened again by the roller cable straightening component located on the right side of the cable heating assembly, thereby improving the straightening efficiency.

[0009] 2. When the cable passes through the thermally conductive isolation ring, the spirally arranged heating rod preheats the heating channel and then heats the cable through the thermally conductive isolation ring. This prevents the cable from hardening and becoming brittle at low temperatures, which is beneficial for subsequent installation. At the same time, the thermally conductive isolation ring isolates the cable and the heating rod, preventing the heating rod from burning the cable's outer sheath. The temperature controller allows for easy control of the heating temperature of the heating rod. Attached Figure Description

The cable is pre-straightened before being heated by the cable heating assembly. After heating, the cable is then straightened again by the roller cable straightening component on the right side of the cable heating assembly, improving straightening efficiency. Simultaneously, when the cable passes through the thermally conductive isolation ring 7, the spirally arranged heating rod 8 preheats the heating channel and heats the cable through the thermally conductive isolation ring 7, preventing the cable from hardening and becoming brittle at low temperatures, which facilitates subsequent installation. The thermally conductive isolation ring 7 also isolates the cable and the heating rod 8, preventing the heating rod 8 from burning the cable's surface. The temperature controller facilitates the control of the heating temperature of the heating rod 8.

The motor 24 drives the second narrow V-belt pulley 25 to rotate, which in turn drives the two first narrow V-belt pulleys 23 to rotate via the belt 28. During the rotation of the first narrow V-belt pulleys 23, the cable is driven to pass between the two second rollers 19. Specifically, each of the two second rollers 19 is provided with annular arc-shaped grooves 20. The upper and lower ends of the cable are attached to and pass through the two arc-shaped grooves 20, and the cable is straightened by the two upper and lower second rollers 19.
