Abstract

An automatic elastic tension compensator for contactor of electric collector is composed of external sleeve pipe with connector, middle sleeve pipe with external spring, and internal sleeve pipe with connector and internal spring. It has high tension-compensating precision.

Description

Technical field [0001] The invention relates to an elastic tension compensator, in particular to a catenary elastic tension compensator applied to railways, subways and urban light rails. Background technique [0002] Elastic tension compensators are mainly used in railways, subways and urban light rails. They mainly compensate the length expansion and contraction caused by thermal expansion and contraction, reduce vibration and maintain balance. The commonly used elastic tension compensators mainly include single spring elastic tension compensator, hydraulic automatic compensator, pendant type compensator and butterfly spring compensator. However, the above-mentioned compensators have certain shortcomings: the elastic tension compensator of a single spring has a small compensation amount and a small scope of application; hydraulic automatic compensators are prone to leakage, resulting in compensation lag; The space is large and the cost is high; the compensation amount of ...
