Abstract

The invention discloses a close-connected coupler, which comprises a tension spring, a coupler body, a hook lock assembly and an uncoupling cylinder. The invention is connected with the central shaft by a flat key and installed in the hook body to form a complete mechanical coupling mechanism. A bushing is installed at the connecting pin to effectively realize self-lubrication and avoid dry friction to reduce coupling performance.

Description

technical field [0001] The invention relates to a close-connected coupler. Background technique [0002] According to different functions, close-fitting couplers are divided into fully automatic couplers, semi-automatic couplers and semi-permanent couplers. Fully automatic coupler can realize automatic connection and disassembly of circuit, gas circuit and mechanical part; semi-automatic coupler can realize automatic connection of gas circuit and mechanical part, but manual uncoupling is required, and manual operation is also required for electrical connection and disassembly; semi-permanent coupler The connection and decomposition of electricity, gas, and machinery all need manual operation. [0003] my country's close-connected couplers are mainly imitated by Japanese Shibata-style couplers, and the manufacturers include Qishuyan Locomotive and Rolling Stock Technology Research Institute Co., Ltd. of China South Locomotive and Sifang Vehicle Research Institute Co., Ltd. o...
