Rolling bearing root part for support hanger

Abstract

The invention discloses a rolling bearing root part for a support hanger, comprising a foraminate welding slice, a trolley upper protective plate, a welding side slice, trolley guide rails, a pin shaft, a level bubble, a trolley guide rail end block, a trolley scale, a first inside assembly, a second inside assembly, a cart upper protective plate, a cart fastening screw, cart rails, a rolling ballguide groove, a cart guide rail end block and a cart scale, wherein the first inside assembly is inlaid in the trolley guide rails through a rolling ball interface thereof, the second inside assemblyis inlaid in the cart rails through a rolling ball interface thereof, the level bubble and the scale are arranged at the lower end of each trolley guide rail, and the scale is arranged at the lower end of each cart rail. The invention has the advantages that the rolling bearing root part for the support hanger has little frictional resistance coefficient to greatly reduce additional force of thesupport hanger to piping thermal expansion, can mark two dimensional displacement, can enhance the safety of running of piping equipment, enable the equipment running to be more stable, reduces the maintenance time, prolongs the service life, enhances the comprehensive benefit of construction, and can be widely applied to industries such as the power industry, the petrochemical industry, the metallurgical industry and the like.

Description

【Technical field】 [0001] The invention relates to the technical fields of industrial engineering, pipeline laying, mechanical installation and maintenance, in particular to an accessory of a high-temperature pipeline support and hanger. 【Background technique】 [0002] At present, in the construction of industrial enterprises, especially when it involves the construction of high-temperature pipelines, for high-temperature pipelines in the vertical plane direction of the support and hanger due to large thermal displacement due to high temperature, the root of the support and hanger or the pipe part are often installed sideways. , and limit the partial installation angle of the tie rod, or use the technology of sliding plate and roller parts for installation. In addition, for the indication of the large thermal displacement of the piping system in the vertical plane direction of the support and hanger due to high temperature, the prior art solves it by setting special displacem...

AI Technical Summary

Problems solved by technology

[0003] However, when the hanger is used for partial installation, the inclined hanger will generate horizontal additional force on the piping system

In the design specification, the maximum allowable deflection angle is 4°, and the corresponding horizontal additional force is 7% of the load of the support and hanger; if the bracket sliding plate or the hanger roller part is used, due to the The friction coefficient is relatively large, the friction coefficient of the polytetrafluoroethylene sliding plate (and steel plate) is ~0.1, the friction coefficient of the sliding shaft working surface (steel and steel) of the roller part is ~0.15, and the corresponding horizontal additional force is the load of the support and hanger 10-15% of that; these additional forces are transferred to the equipment interface and civil structure through the piping system, which will affect the normal operation of the piping system and equipment and reduce the safety of the project

[0004] The special displacement indicator can only mark the local thermal displacement of the piping system, and cannot fully reflect the thermal expansion of the entire piping system, so it cannot meet the requirements for monitoring the operation of the support and hanger system
