Abstract

A soft crass spring compensator comprises a protective device, a left draw hook, a right draw hook, a left outer supporting pad and a right outer supporting pad; wherein, the left draw hook passes through the left outer supporting pad and is fixedly connected with the right outer supporting pad; the right draw hook passes through the right outer supporting pad and is fixedly connected with the left outer supporting pad; the left draw hook is vertical to the right draw hook to be installed, an outer spring is sheathed on the left draw hook and the right draw hook, the inner side of the outer spring is sheathed and connected with an inner spring, and the outer side of the outer spring is provided with a shell; one end of the shell is fixedly connected with the left outer supporting pad or the right outer supporting pad. The invention adopts the springs to rotate left and right for use in a way of matching inside and outside, and a counter balance spring twists after being applied with force, so that the working stability and compensating precision of the compensator is greatly improved; by adopting the structural style of combining the inside and the outside springs, the space is fully utilized to lead the structure of the produce to be compact; the protective device is used for limiting overload, so that the security of the compensator and the system is ensured.

Description

Technical field [0001] The invention relates to a soft span spring compensator, in particular to a spring compensator applied to the soft span of electrified railways, subways and urban rail transit. Background technique [0002] Spring compensators are mainly used in railways, subways and urban light rails, mainly to compensate for the length expansion caused by thermal expansion and contraction, so as to reduce vibration and maintain balance. The previous spring compensator was mainly composed of single-rotation and single-layer coil springs, which caused the compensator's volume and weight to be too large and difficult to install. The coil springs would be twisted and bent along the direction of rotation after being stressed. The friction force generated between the hook and the spring reduces the compensation accuracy of the compensator, and the safety of the system is not very good. Summary of the invention [0003] In order to overcome the above shortcomings, the technical...
