Rotating limiting support for thermal pipe and rotating limiting method of support

Abstract

The invention discloses a rotating limiting support for a thermal pipe. The support comprises a pipe clamp, rotating shafts and a supporting system, wherein the supporting system comprises a supporting frame and a supporting plate; the supporting frame comprises a transverse supporting frame and longitudinal supporting frames; the rotating shafts comprise an upper rotating shaft and a lower rotating shaft, the lower end of the upper rotating shaft is welded at the upper end of the pipe, and the upper end of the lower rotating shaft is welded at the lower end of the pipe; rotating shaft grooves are located in the supporting system; and the rotating shafts are sleeved with the rotating shaft grooves. The support overcome defects that only linear displacement in one or two directions can be limited and angular displacement is limited on the premise that the linear displacement of the position of a supporting point is limited in the prior art are overcome; and the rotating limiting support has the advantages that the rotating shafts are increased on the pipe clamp, and limiting supporting is designed, so that the linear displacement of the pipe in a heated state is limited, the angular displacement is allowed on a certain plane, and partial swelling stress is released. The invention further discloses a rotating limiting method of the rotating limiting support for the thermal pipe.

Description

technical field [0001] The invention relates to the field of heat pipe supports, more specifically, it is a rotation limiting support for heat pipes. The invention also relates to a rotation limiting method of a rotating limiting support for a thermal pipeline. Background technique [0002] At present, in the thermal pipeline design, the pipeline has six degrees of freedom in the directions of X, Y, Z, RX, RY, and RZ at the supporting point. According to the needs of pipeline design, different supports and hangers are selected to constrain one of them. degrees of freedom or certain degrees of freedom to achieve the purpose of safe and economical operation of thermal pipelines; currently widely used types of supports and hangers (or called restraint forms) are: spring support and hanger, rigid hanger, sliding support , Rolling bracket, guide bracket, limit device, fixed bracket, vibration reduction device and damping device, etc. [0003] Among the above types of supports a...

Problems solved by technology

[0004] In engineering design, sometimes it is necessary to limit the linear displacement of the fulcrum in three directions, but not to limit the angular displacement of the pipeline on a certain plane; The support needs to limit the linear displacement in three directions at the fulcrum, but not limit its angular displacement, so as to realize the use of the angular displacement of the pipeline itself to compensate the elastic deformation of the pipeline and achieve the effect of releasing the thermal stress of the pipeline; Under the action of stress, the thrust of the intermediate support will be very small; however, there is no suitable support and hanger to choose from the existing support and hanger forms.

[0005] The conventional fixed support, the pipe clamp and the pipe, the base and the supporting foundation are all welded and fixed, and the linear displacement and angular displacement at the fulcrum are all locked; the current limit device can only limit the movement in one direction or two directions. The fixed bracket limits the linear displacement and angular displacement in all directions; in the form of the existing support and hanger, it is still impossible to limit the angular displacement under the premise of restricting the linear displacement in the three directions of the fulcrum position.
