Description

Technical Field

[0001] This utility model relates to the field of wire and cable equipment technology, specifically to a centering conductor frame suitable for large-diameter cables. Background Technology

[0002] In fields such as power engineering and telecommunications engineering, the laying and installation of large-diameter cables is an important and challenging task. With the continuous growth of electricity demand and the rapid development of communication technology, the application of large-diameter cables is becoming increasingly widespread, and the requirements for accuracy and safety during their laying process are also increasing.

[0003] Existing cable centering conductor frames mostly use guide rollers. However, when producing large-diameter cables, the guide rollers need to be made very large, which makes the conductor frame difficult to process and increases the processing cost. In addition, the centering of large-diameter cables is poor due to the guide roller type of centering conductor frame. Utility Model Content

[0004] The purpose of this utility model is to provide a centering conductor frame suitable for large-diameter cables. It has the advantages of compact design, low cost, flexible cable rollers, good centering, and suitability for centering different specifications of cables produced on the same production line. It solves the problem that when using a guide wheel type conductor frame to center large-diameter cables, it is necessary to manufacture large guide wheels, which leads to increased processing costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centering conductor frame suitable for large-diameter cables, comprising: a support mechanism, wherein the support mechanism includes a column, a base plate is provided at the bottom end of the column, and a limiting cylinder is provided at the top end;

[0006] A lifting mechanism, comprising a lifting screw, which is slidably embedded in a column, and a support column is constructed at the top of the lifting screw;

[0007] The centering mechanism includes a mounting base, the bottom end of which is fixed to the upper end face of the support column, and two positioning blocks are symmetrically arranged at the top of the mounting base. The top of each of the two positioning blocks on an adjacent side is provided with a mounting surface.

[0008] Preferably, the chassis is square in shape, and the length and width of the chassis are both greater than the length and width of the column.

[0009] Preferably, the outer edge of the support column is spirally connected with a lifting nut, one end of which passes through the limiting cylinder and extends into the limiting cylinder.

[0010] Preferably, a limiting groove is formed on the outer edge surface of the lifting screw, the bottom end of the limiting groove extends out of the bottom end of the lifting screw, the top end is placed inside the lifting screw and is arranged in an arc shape, and two mounting holes are symmetrically formed at the top of the support column.

[0011] Preferably, both mounting surfaces are provided with an angle between themselves and the horizontal plane, and the angle value of the angle is 45°. Both mounting surfaces are provided with a rotating shaft, and the two rotating shafts are staggered and perpendicular to the mounting surfaces.

[0012] Preferably, each of the rotating shafts is fitted with a roller on its outer edge, and a bearing is provided inside the end of the roller away from the mounting surface, with the inner edge of the bearing connected to the outer edge of the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention features a column, a lifting mechanism, and a centering mechanism. A lifting screw slides into a limiting cylinder, and a lifting nut, spirally connected to the outer edge of the limiting cylinder, abuts against the limiting groove, thus limiting the lifting mechanism. The height of the centering mechanism can be adjusted by changing the length of the lifting screw extending into the limiting cylinder. Rotary shafts, staggered on two mounting surfaces, center large-diameter cables using rollers on their outer edges. When cable diameters differ, the position of the lifting screw can be adjusted to ensure consistent center height. This invention is compact, low-cost, and features flexible cable rollers with good centering performance, making it suitable for centering cables of different specifications produced on the same production line.
