Embodiment 1

[0046] Such as figure 1 with figure 2 As shown, a protective device for cable maintenance includes a rope 1 and a cable clamp 2;

[0047] The two ends of the rope 1 are respectively fixedly connected with the cable clamp 2, the cable clamp 2 is in the shape of pliers, and the rope 1 is fixedly connected with the hand-held part of the cable clamp 2; when in use, the staff clamps the two cable clamps 2 respectively on the cables that need to be repaired. On both sides, the two cable clamps 2 are connected by a rope 1;

[0048] When the cable that needs to be repaired is repaired, the staff will tighten the rope 1, and the distance between the two cable clamps 2 will be shortened by tightening the rope 1, and the distance between the two cable clamps 2 will be shortened to make the two The cables between the two cable clamps 1 are loosened. Since the staff maintains the cables in the air, the loosened cables can be convenient for the staff to maintain the cables, and there wil...

Embodiment 2

[0050] Such as image 3 , Figure 4 with Figure 5 As shown, this embodiment relates to a protective device for cable maintenance, and its structure is roughly the same as that of Embodiment 1. This embodiment is further optimized on the basis of Embodiment 1: the cable clamp 2 includes a clamping end and a hand-held end, and the clip Both clamping surfaces of the holding end are provided with arc-shaped depressions, and the holding end is fixedly connected with the rope 1 .

[0051] The cable clamp 2 is two intersecting clamp bodies, and a pin shaft is inserted at the intersection point of the two clamp bodies. The two clamp bodies can clamp the article through the pin shaft. The cable clamp 2 includes a clamping end and a hand-held end. The two clamping surfaces of the clamping end are provided with arc-shaped depressions. The setting of the arc-shaped depressions can increase the contact area between the cable clamp 2 and the cable, increase the friction between the cable...

Abstract

The invention discloses a protection device for cable maintenance. The protection device comprises a rope and a cable clamp. The number of the cable clamps is two, and the two cable clamps are fixedly connected to the two ends of the rope respectively. The two cable clamps are clamped on the two sides of a cable part to be maintained respectively, the two cable clamps are connected, tightened and fixed through the rope, the cable part to be maintained is replaced through mutual cooperation of the two cable clamps and the rope, the cable part to be maintained is loosened, and other cable parts are still in a straightened state; by loosening the part of the to-be-maintained cable, a worker can conveniently maintain the part of the to-be-maintained cable; the problems that when an aerial cable is maintained, the cable is in a suspended and straightened state all the time, no redundant cable is loosened, and maintenance is not easy are effectively solved.

Description

technical field [0001] The invention belongs to the field of electric safety equipment, in particular to a protective device for cable maintenance. Background technique [0002] With the development of electric power, electric power is gradually applied to every corner. In the process of electric power use, the role played by cables as transmission lines is irreplaceable; due to geographical, environmental and artificial planning reasons during the use of cables, it is possible to set On the surface, underground or in the air, during the use of cables, due to environmental factors, cables will inevitably be affected to varying degrees. [0003] When the cable is erected in the air, there are many factors that are affected by the environment. The cable is installed in the air to withstand the erosion and damage of wind, rain and temperature. The wind force has a particularly serious impact on the cable. When the wind force is greater, the greater the tension on the cable , p...
