Description

A split hoop spacer

technical field

The invention relates to the technical field of high-voltage transmission lines, in particular to a split hoop spacer.

Background technique

After retrieving relevant patent documents, a split-type hoop spacer with the same structure as the present invention has not yet been retrieved. With the rapid development of the power industry and the continuous growth of electricity demand, the requirements for high-voltage transmission lines are getting higher and higher. In the squirrel cage jumper of the UHV transmission line steel pipe skeleton, in order to support the jumper and prevent whipping between jumpers In order to prevent impact and collision, hoop-type spacers are required on the steel pipe skeleton. The existing hoop-type spacers are generally made of cast steel for integral casting, and pores and trachoma are prone to occur during pouring; because the pouring is an integral structure, thus A small trachoma in one part will lead to the scrapping of the entire spacer, resulting in low production efficiency, low pass rate, low versatility, and low strength. Each product needs to be molded separately, and the cost of mold making is relatively high. Due to the overall structure, It cannot be disassembled and has a large volume, which is difficult for installation workers to operate at high altitudes; for high-voltage transmission lines, the existing integrally cast hoop spacer is difficult to meet the requirements, so it is necessary to design a split hoop spacer to meet High voltage transmission line requirements.

Contents of the invention

The object of the present invention is to provide a split-type hoop spacer that is easy to process and install, has strong versatility, high strength, and is convenient for quick assembly.

To achieve the above object, the present invention adopts the following technical solutions:

A split-type hoop spacer, which is composed of a hoop, a frame plate, a wire clip, a frame plate connecting seat, a wire clip connecting plate, and an anti-skid pad. The hoop is two symmetrical semicircular rings, and the An annular hoop formed by connecting bolts, and two frame plate connection seats are welded on the semicircular ring; an anti-slip pad is provided on the inner surface of the hoop, and an anti-slip pattern is provided on the contact surface between the anti-slip pad and the frame ; The frame plate is connected with the frame plate connecting seat through bolts; the frame plate is an arc-shaped plate body with a toothed structure; Formed into one body; the wire clip is set on the wire clip connecting plate.

The hoop is formed by winding a steel strip.

The frame plate is a structural plate body formed by cutting and forming a steel plate.

The section of the connecting part of the clamp connecting plate and the frame plate is a cross-shaped structure.

The wire clamp is composed of a wire clamp body, a cover plate and a rubber tile, and the cover plate is hinged with the wire clamp body; rubber tiles are respectively provided on the inside of the wire clamp body and the cover plate; the rubber tile and the jumper contact surface It is equipped with anti-skid patterns that match the shape of the jumper's external structure.

The anti-slip pad is a semicircular ring structure made of rubber material that matches the inner shape of the hoop.

When in use, select the appropriate hoop according to the outer dimensions of the steel pipe skeleton, fix the hoop on the steel pipe skeleton, select the frame plate according to the split structure, and connect the frame plate to the frame plate connecting seat on the hoop through bolts. The wire clamp is fixed on the wire clamp connection plate on the frame plate, and then the jumper is pulled into the wire clamp, and the wire clamp cover is covered and locked to effectively space the jumper wires.

The advantages of the present invention are: because the hoop is formed by winding the steel strip; thereby effectively avoiding the defects of the cast steel hoop during pouring, and improving the strength of the hoop; Support strength, and avoid mold opening, reduce production costs; because there is an anti-slip pad in the hoop, the reliability of the connection between the entire spacer and the steel pipe skeleton is improved, and it is not easy to rotate; because the frame plate and the clamp connection plate form a cross shape Crossover and welding connection; thus ensuring that the frame plate and the clamp connection plate are not easily deformed after the jumper is installed; since the contact surface between the rubber tile and the jumper is provided with anti-skid lines that match the outer shape of the jumper, the jumper is not easy Relative to the wire clip, it effectively protects the outer surface of the jumper; due to the split structure, suitable parts can be selected for combination according to the design requirements, which is versatile and easy to construct; due to the simple structure and easy use , so it has great practical and promotional value.
