Embodiment Construction

[0043] like Figure 1 to Figure 6 As shown, the development is a 10KV distribution line cable erection fixture, which can firstly solve the problem of non-damage connection, and secondly has a certain degree of freedom, can meet the requirements of cable vibration, flexible connection, and avoid stress concentration at the connection point.

[0044] At the same time, the structure of the cable connector provided by the present invention is as follows:

[0045] The first shell 1 and the second shell 2, which are arranged symmetrically and fastened to each other, adopt sheet metal parts or cast aluminum parts, wherein the first shell 1 and the second shell are symmetrical to each other in structure, and use a tight The solid bolts are tightened to form an integral body. The symmetrical layout is easier to realize in industrial manufacturing, and it is convenient for high-altitude operation and installation process.

[0046] The shell is stamped and formed, with edges for faste...

Abstract

The invention discloses a 10KV distribution line cable erection fixture and an application method and provides a convenient and fast device capable of effectively avoiding adverse impact caused by wind vibration. The 10KV distribution line cable erection fixture comprises a shell, wherein a main cavity is formed at the middle of the shell, and two assistant cavities are formed on the two sides; three rope sheaves and a pair of assistant locking mechanisms are mounted in the main cavity; the three rope sheaves are arranged in a shape of Chinese character 'Pin'; the rope sheaves are close to an entrance, and the locking mechanism is close to an exit. When a cable passes by, a clamping force is formed against the cable under the effect of reversed tension of the cable; a pull rod is mounted in each assistant cavity, and the tensioning effect is good; and three rope sheaves are arranged inside, the cable is wound on the three rope sheaves which are mutually bent in a roundabout manner, and locking and fixing are formed in the roundabout bending process to firmly lock the cable inside and form a relatively good locking effect.

Description

technical field [0001] The invention relates to a hardware clamp used in cable erection, in particular to a 10KV power distribution line cable erection clamp. Background technique [0002] Usually, in a 10 kV transmission circuit, tension clamps are used between two adjacent poles for connection, and insulators are used. Generally speaking, steel hoops are first used to fix the top of the pole, and then a cross-arm is formed by using angle steel, etc., and one end of the insulator is fixed on the cross-arm, and the other end of the insulator is connected to a tension clamp, wherein the function of the tension clamp is to make the Cable tensioned. [0003] The above-mentioned structure is an existing common structure. The problem is that the tension clamp is generally fastened by U-shaped bolts, which is a rigid connection, and a large stress concentration is formed at the fastening point, especially under the action of external wind vibration. , the fixed point is repeated...
