Supporting unit and supporting device for repairing umbrella skirt of insulator

Abstract

The invention provides a supporting unit and a supporting device for repairing an umbrella skirt of an insulator. The supporting device comprises at least two supporting units. Each supporting unit comprises a pedestal, and front and rear supporting rollers which are rotatably arranged on the pedestal and extend along the left and right directions of the rotation axis, wherein the front and rear supporting rollers are of sheet structures with the thickness no greater than the distance between adjacent umbrella skirts of a corresponding insulator. The front and rear supporting rollers can be conveniently inserted in the space between adjacent umbrella skirts, different supporting positions can be changed, and the application scope of the supporting unit is expanded. The problem of a limited application scope caused by the fact that a supporting unit can only support the end portion of the insulator in the prior art is solved. At least two supporting units are used to set appropriate bearing points according to the positions of force application points of an umbrella repairing die to minimize bending deformation during repairing the umbrella skirt of the insulator, and the umbrella skirt repairing effect and insulator quality are ensured.

Description

technical field [0001] The invention relates to a support unit and a support device for insulator shed repair. Background technique [0002] Composite insulator is a special insulation control, which plays the role of increasing creepage distance in overhead transmission lines. In the manufacturing process of composite insulator, it is necessary to use injection machine to inject umbrella skirt into the outer layer of insulator mandrel. After injection molding, umbrella There may be defects on the skirt, such as damage, cracks or incomplete vulcanization, etc. At this time, it is necessary to use the parachute repair mold to repair the insulator under pressure. When the umbrella skirt is repaired, the insulator needs to be rotated and supported. The supporting method in the prior art is as follows: figure 1 As shown, the two ends of the insulator are rotatably supported by the supporting trolley 1, which provide upward supporting force F1 respectively. When the umbrella rep...
