Wiring traction device

Abstract

The invention discloses a wiring traction device. The wiring traction device comprises a hemispherical movable cavity and supporting plates fixed at two ends of the movable cavity, wherein blind holes are formed in the bottom surfaces of the two supporting plates; two mutually perpendicular clamping plates are arranged at the bottoms of the blind holes in a rotating manner through torsional springs; the movable ends of the clamping plates protrude out of the blind holes; the bottom of the movable cavity is open, and a barrel-shaped extending part is fixed at the bottom of the movable cavity; and mutually communicating openings are formed in the movable cavity and the extending part. The movable cavity is in a hemispherical shape, it is allowed that when a cable has penetrated from inner walls on two sides of a wiring box, a cable in a wire pipe arranged at the bottom of the wiring box can be pulled out without influence to each other, so that the applicability of the device is improved.

Description

technical field [0001] The invention relates to a power system, in particular to a wiring traction device. Background technique [0002] Power cable wiring is an important part of the power system. Power cable wiring should meet the following requirements: 1. The laying method of cable wiring should be based on factors such as engineering conditions, environmental characteristics, cable type and quantity, and meet the requirements of reliable operation, easy maintenance and 2. The selection of the cable path should meet the following requirements: 1) The cable should be protected from mechanical force, overheating, corrosion and other hazards; 2) It should be easy to lay and maintain; 3) It should be kept away from the site The planned construction land or construction land; 4) The cable path should be the shortest when the safety conditions are met; 3. When the cable is laid indoors, in the cable trench, cable tunnel and electrical shaft, the flammable outer surface should ...

Problems solved by technology

Due to the limitation of the terrain, the cable steel pipe is usually bent according to the corner of the terrain or the corner of the building when laying. The other end is connected with multiple cables wrapped with adhesive tape, and then one end of the steel wire is manually pulled until the wrapped wire ends completely pass through the cable duct. During the pulling process, the straight line cable duct requires less labor. , but when the cable enters the bend of the cable duct, the cable duct is deformed and the internal cross-sectional area is reduced. It is very difficult for multiple cables to pass through, which greatly increases the labor intensity and is easy to During the pulling, the protective layer of individual cables is worn or the cable is directly pulled off, especially when the thread end passes through the cable duct, the thread end will contact and rub against the outer edge of the cable duct, resulting in a large area on the surface of the cable. wear and tear
