Insulator horizontal tensile testing machine

Abstract

The invention relates to an insulator horizontal tensile testing machine, which comprises a working platform, wherein a rail is arranged on the working platform; the rail is provided with a headstock and a tailstock; the side wall of the working platform is provided with a plurality of through pin holes; the tailstock comprises a traveling mechanism, locking mechanisms and a fine adjustment mechanism, and is provided with a travel switch; the traveling mechanism comprises a driving motor, and an output end of the driving motor drives a pulley block through a middle transmission mechanism; the locking mechanisms are divided into two groups and are symmetrically arranged on two sides of the tailstock, each group of the locking mechanisms comprises a locking motor, an output end of the locking motor is connected with a transverse screw rod, a sliding block provided with a plug pin is inserted on the screw rod, and the position of the plug pin corresponds to the through pin holes; and the fine adjustment mechanism comprises a fine adjustment motor, an output end of the fine adjustment motor is connected with a rotating wheel, a longitudinally arranged screw rod is inserted on the rotating wheel, and the front end of the screw rod is connected with a tailstock clamp. The insulator horizontal tensile testing machine is also provided with a loading cylinder which is controlled by a remote measurement and control system. The insulator horizontal tensile testing machine adopts the movable tailstock, and has macro-movements, positioning and micro-adjustments so that the distance between the headstock and the tailstock on the working platform is convenient to adjust to adapt to tensile tests of insulators with different lengths.

Description

technical field [0001] The invention relates to a tensile testing device, in particular to a horizontal tensile testing machine for insulators. Background technique [0002] The mechanical load performance of composite insulators directly affects its reliability. The length of the composite insulator increases with the increase of the voltage level, ranging from 300mm to 12000mm. At present, the length of ±800kV DC composite insulators has reached 12m, and the mechanical damage load has reached 900kN. According to the requirements of relevant national standards and industry standards, it is necessary to conduct tests on mechanical properties such as mechanical failure load and mechanical load tolerance. The horizontal tensile machine is an indispensable test device. In the previous devices, the tensile parts at both ends of the horizontal tensile machine are mostly fixed, and the length required for the device can only be adjusted by connecting steel connecting rods of di...

AI Technical Summary

Problems solved by technology

In the previous devices, the tensile parts at both ends of the horizontal tensile machine are mostly fixed, and the length required for the device can only be adjusted by connecting steel connecting rods of different lengths to the test product. The steel connecting rods are heavy and difficult to operate. extremely inconvenient

Some also use a hand-operated mobile tailstock horizontal tensile test device. Because the weight of the tailstock is heavy, the labor intensity of the operator is high, and after positioning, it is necessary to manually install the bearing pin to fix it, and the operation is also inconvenient.
