Tension tester lifting transfer device

Abstract

The invention relates to a hoisting turnover device of a tensile testing machine, comprising a horizontal tensile testing machine; a lifting unit, the lifting unit comprising a pair of hoisting gantry mounted on the side ends of the horizontal tensile testing machine in the direction of the long axis. A crossbeam is also arranged between the two lifting gantry frames, and several suspension hooks distributed side by side are connected to the lower end of the crossbeam, and the crossbeam is driven by a drive mechanism to reciprocate in the horizontal direction and the vertical direction; a turntable. The advantage of the present invention is that: by adding a pair of lifting gantry frames to the horizontal tensile testing machine, and through the cooperation between the beam, the hook and the driving mechanism, the composite insulator can be installed on the turnover car and the horizontal tensile testing machine. It can be hoisted back and forth, thereby reducing manual handling. Moreover, through the lifting and lowering of the beam, the reciprocating movement on both sides of the turnover car can be realized, and the insulators on both sides of the turnover car can be lifted without turning the turnaround car, which is very convenient.

Description

technical field [0001] The invention relates to the field of detection of composite insulators, in particular to a lifting and turning device of a tensile testing machine. Background technique [0002] As a new generation of insulator products, composite insulators usually consist of a mandrel, a silicone sheath wrapped around the mandrel, an umbrella group, and fittings at both ends. Composite insulators are a special insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles. With the development of science and technology, many disc-shaped insulators were hung on one end of the high-voltage wire connection tower. It is to increase the creepage distance. It is usually made of glass or ceramics. called insulators. Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two functions must be guara...

AI Technical Summary

Problems solved by technology

When using the above-mentioned method for testing, when the length of the composite insulator to be tested is relatively long, it is more troublesome to carry out manual handling and consumes a lot of manual labor; secondly, when testing, usually a Batches of composite insulators are placed on transfer vehicles for transportation. In order to transport more composite insulators at one time, traditional transfer vehicles adopt a design that can be loaded on both sides, and because the length of composite insulators is longer Therefore, when transporting, the composite insulator on the side close to the horizontal tensile testing machine is more convenient to load and unload, but for the composite insulator on the other side, it is necessary to turn the entire transfer vehicle to the rear before loading and unloading, which is more troublesome
