Abstract

The present invention relates to a test rack for a wire-releasing pulley, which includes a connected support plate, a wire-releasing pulley, a simulated indenter, a back plate for the indenter, a steel wire rope, a triangular pull plate, and a main rod for fixing the test rack. Main pole two; the pay-off pulley includes a hub and a wheel groove arranged on the rim of the hub. The test frame for a wire-feeding pulley provided by the invention has the advantages of high test accuracy and stability, simple operation and high safety.

Description

technical field [0001] The invention relates to a testing tool for electrical equipment, in particular to a test frame for a wire-drawing pulley. Background technique [0002] Transmission line pay-off block is one of the main equipment necessary for the construction of transmission line engineering. The pay-off block is closely related to the construction of pay-off, tightening and attachment installation. The pay-off pulley set on the pay-off block is generally made of nylon, which requires light weight and high precision, so it has the characteristics of difficult processing control and unstable quality, especially the pay-off pulley on the large-diameter pay-off block. Its quality control is more difficult. my country's industry standards require that pulleys need to be sampled when they leave the factory. [0003] The existing pay-off pulley test frame is composed of lead wires, steel wire rope sleeves, connecting pipe protection devices and rotary connectors connected...
