Description

Technical Field

[0001] The utility model relates to the technical field of protective devices, in particular to a protective device used for pipeline position limiting. Background Art

[0002] The pipeline limit protection device is a device used to constrain or limit the displacement in a certain direction at the pipeline support point to ensure that the torsion angle of the elastic component does not exceed a certain limit value. This device can be used in various pipeline systems, such as pipeline systems in the petroleum, chemical, electric power and other industries.

[0003] The existing pipeline protection devices usually directly wrap the buffering foam on the outside of the pipeline when buffering the pipeline. This buffering method is simple to install, but because there is only one layer of buffering foam, the shock-absorbing effect on the pipeline is not good, and the pipeline cannot be limited. In view of this, we provide a protection device for pipeline limiting. Utility Model Content

[0013] 1. The utility model uses a shock-absorbing spring between the first mounting block, the second mounting block and the shock-absorbing plate to make the shock-absorbing plate slidably connected with the first mounting block and the second mounting block. When installing the device, after the delivery pipeline is placed on one of the shock-absorbing plates just above the top of the first mounting block, the second mounting block is closed toward the delivery pipeline, and all the shock-absorbing plates are made to fit with the outer wall of the delivery pipeline.
