Problems solved by technology

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 the butterfly spring compensator is small, and the measurement of the compensation amount is inaccurate

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] like figure 1 The catenary elastic tension automatic compensator shown includes a left pull hook 1, a right pull hook 2, a left outer support pad 3, and a right outer support pad 4. In order to prevent the pull hook from deforming when the compensator is stressed, the free expansion and contraction of the spring 5 is affected. , a support block 9 is arranged at the bend of the left outer support pad 3 and the right outer support pad 4, the left pull hook 1 passes through the left outer support pad 3 and is fixedly connected with the right outer support pad 4, and the right pull hook 2 passes through the right outer support pad 4 is fixedly connected with the left outer support pad 3, the left hook 1 and the right hook 2 are installed perpendicular to each other, and at least two springs are set on the left hook 1 and the right hook 2 between the ...

Abstract

An automatic elastic tension compensator for the contactor of electric collector is composed of left and right external suporting pads, left pull hook passing through left external supporting pad and fixed to right one, right pull hook passing through right external supporting pad and fixed to left one, at least two serial springs on said left and right pull hooks, and internal supporting pad between said springs. Its advantage is 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 ...
