Sulfur hexafluoride supplementary gas overhaul vehicle

Abstract

The invention relates to a sulfur hexafluoride supplementary gas overhaul vehicle. The overhaul vehicle comprises a vehicle frame. The vehicle frame comprises a base and a bearing groove matched witha gas cylinder in shape. The bearing groove is of a frame structure. The base comprises two vertical boards symmetrically arranged on the two sides of the bottom of the bearing groove. Vertical handles are arranged at the ends, close to a gas cylinder opening, of the vertical boards. Two supporting wheels are further arranged on the outer sides at the ends, close to the bottom of the gas cylinder,of the vertical boards. A first joint is arranged in the middle position of the two vertical boards. A second joint is arranged at the ends, close to the gas cylinder opening, of the two vertical boards. The first joint is connected with a lead screw. The other end of the lead screw penetrates through the second joint and is connected with a rotation wheel. The lead screw is in threaded connection with an adjusting ring. Connecting columns are symmetrically arranged on the outer wall of the adjusting ring. Self-locking gas springs are hinged to the tail ends of the connecting columns. The other ends of the self-locking gas springs are hinged to back-folding rods. The sulfur hexafluoride supplementary gas overhaul vehicle adapts to automobiles in different heights, can move in a narrow andsmall space and is simple in structure, small in weight, small in occupied space, convenient to operate and capable of saving manpower.

Description

technical field [0001] The invention relates to a tool cart, in particular to a sulfur hexafluoride supplementary gas inspection and repair vehicle. Background technique [0002] In substation 220-500KV combined electrical appliances, due to product quality or installation problems, the leakage and leakage of sulfur hexafluoride gas often exist objectively, which not only reduces the insulation level of equipment, but also causes certain economic losses. Since the existing sulfur hexafluoride gas cylinders cannot be loaded into the car or the gas cylinders cannot be easily and labor-savingly loaded into the car, they can only be loaded by hand or transported to the gas supply site by hand, and the existing gas cylinder transport vehicles are also It cannot meet the requirements of shifting in narrow gaps, especially the regular gas replenishment at multiple points in one station. The gas cylinder can only be rolled in place by hand, which is labor-intensive, requires a lot o...

AI Technical Summary

Problems solved by technology

However, the sulfur hexafluoride gas cylinder transport vehicle of this patent can only move horizontally, cannot move vertically, and cannot meet the requirements for shifting in narrow gaps, and only the front or rear rollers are in contact with the carriage, so loading and unloading the vehicle is time-consuming and laborious. The labor intensity is high, the structure is also complicated and heavy, and the operation is troublesome
