Technical Field

The invention relates to a lockable spring support, in particular to a lockable spring support with a universal ball head.

Background

In the fields of electric power, petrochemical industry and the like, because of additional displacement and thermal expansion, thermal displacement can be generated at support points of some equipment, and in order to reduce severe change of support point load caused by the thermal displacement, a spring support is usually used for supporting pipelines and the equipment. The spring support is a functional structural component which bears the load of the pipeline by virtue of the compression of the spring, and the supporting force of the spring support is increased along with the increase of the compression deformation of the spring when the pipeline is vertically displaced.

Because of additional displacement and thermal expansion, the supporting point of the spring bracket can generate horizontal thermal displacement, and a polytetrafluoroethylene sheet is usually padded to reduce friction force during actual installation, so that the disadvantages that the polytetrafluoroethylene material cannot resist high temperature and is easy to damage are realized. As the support load increases, frictional forces typically prevent normal horizontal thermal displacement of the pipe and equipment.

When a pressure pipeline is subjected to hydrostatic test or the pipeline and equipment are subjected to acid washing, the spring support needs to be locked, and the traditional spring support is inconvenient to lock after being installed. In addition, under some abnormal conditions, the pipeline and the equipment pivot can generate abnormal vertical displacement due to abnormal load, the pipeline and the equipment sink and the like, the normal operation of the equipment is seriously influenced, and great potential safety hazard is brought.
