Fixing apparatus used for cable head replacement in box body

Abstract

The invention relates to the technical field of power distribution network auxiliary equipment, more specifically a fixing apparatus used for cable head replacement in a box body. The fixing apparatuscomprises a cable head fixer and a fixed frame; a rotary platform is connected between the cable head fixer and the fixed frame; the fixed frame comprises a first telescopic rod and a second telescopic rod which support the left and right sides of the box body, and a third telescopic rod which supports the ground or the upper and lower sides of the box body; one ends of the first telescopic rod,the second telescopic rod and the third telescopic rod are all fixed with the rotary platform while the other ends are connected with a clamping assembly fixed with the box body; the first telescopicrod and the second telescopic rod are arranged on the same straight line; and the third telescopic rod is perpendicular to the straight line where the first and second telescopic rods are located. Byvirtue of the fixing apparatus, the cable head can be fixed in the box body safely and stably, thereby providing a reliable fixation condition for cable head replacement, saving time in the fixing process, adjusting the cable head in various angles, and achieving relatively high safety and convenience.

Description

technical field [0001] The invention relates to the technical field of distribution network auxiliary equipment, and more specifically, to a fixing device for replacing cable heads in a box. Background technique [0002] With the development of the distribution network cable process, many cities or towns use underground cable laying to replace the operation of overhead lines. With the continuous laying and use of cables, there are extremely complicated cable heads in the matching box-type transformers, distribution boxes, and cable branch boxes. With the continuous development of distribution network lines, the load continues to increase, causing the cable terminal in the cabinet to explode or catch fire. Because the cable head is generally all in the box, the space in the box is limited, and the reserved length of the cable on the shelf is limited at the lower end of the box, so it is impossible to pull it out of the reserved cable body to replace the cable head. The cons...

With the continuous development of distribution network lines, the load continues to increase, causing the cable terminal in the cabinet to explode or catch fire

Since the cable head is generally in the box, the space in the box is limited, and the reserved length of the cable on the rack is limited at the lower end of the box, so it cannot be pulled out of the reserved cable body to replace the cable head.

The construction environment for replacing the cable head is relatively complicated, and the site is inconvenient to use. It is impossible to use conventional ropes to fix the cable head, and many boxes do not have the conditions for binding or hanging

[0003] At present, the fixing methods for cable head replacement include binding, using wooden sticks, and hanging from the top of the box to bind and fix. These methods have a great impact on the quality of the cable head manufacturing process, and there are many hidden risk points. Moreover, these methods cannot meet people's ever-increasing demand for power and the higher repair time limit for construction units.

In addition, these methods are time-consuming, and there is a danger of falling off in the binding technology, and the shaking of the cable head during production has an impact on the construction process
