Description

Technical Field

[0001] The present application relates to the technical field of thermal pipeline design, and in particular to a fast-assembly multi-degree-of-freedom stepless adjustment pipeline support. Background Art

[0002] Pipe supports can bear the weight of pipelines, increase pipeline rigidity, avoid pipeline vibration and deformation, and control the size and direction of pipeline thermal displacement to ensure the safe operation of pipeline systems and connecting equipment. They are an important part of pipeline systems.

[0003] The pipeline of the fusion experimental device will go through several test cycles during its service life. Each test cycle will go through at least three different temperature conditions. The thermal expansion amount of each condition is different. At this time, it is necessary to restrain or release the thermal displacement caused by thermal expansion by finely adjusting the degrees of freedom of the bracket in all directions to meet the requirements of safe operation of the pipeline. At the same time, since the thermal pipeline of the fusion experimental reactor has initial displacements at many connection parts, the horizontal variables of these displacements under different conditions increase or decrease in proportion to the vertical variables, so it is necessary to adjust the horizontal and vertical support restrictions synchronously. The existing brackets cannot achieve stepless fine-tuning or rapid adjustment in the horizontal and vertical directions at the same time, which requires multiple adjustments or replacements of the brackets. Not only is the construction efficiency low, but it may even affect the safe operation of the pipeline in serious cases. Utility Model Content

[0035] like Figure 1-Figure 2 As shown, an embodiment of the present application provides a quick-assembly multi-degree-of-freedom stepless adjustment pipe support, which includes a pipe clamp assembly, a first base 7 and a second base 9.

[0036] The pipe clamp assembly has a first positioning portion and a second positioning portion, and the first positioning portion and the second positioning portion serve as connecting parts of the pipe clamp assembly to be connected with other structures. The pipe clamp assembly is used to clamp the pipe.

[0037] The first base 7 has a first positioning cavity and a second positioning cavity, the first positioning part and the second positioning part are respectively located in the first positioning cavity and the second positioning cavity and are respectively tightly matched with the first base 7, wherein the first positioning part and the second positioning part can be respectively adapted to the shape of the first positioning cavity and the second positioning cavity, or can be unadapted, that is, the first positioning part and the second positioning part can be in a freely movable state, the first positioning part and the second positioning part can be tightly matched with the first base 7 through the upper tightening bolt 6 so that the first positioning part and the second positioning part are respectively fixed in the first positioning cavity and the second positioning cavity, so that the pipe clamp assembly can constrain the angle of the pipeline in the vertical plane; the first base 7 also has a positioning cylinder 7-3, the external shape of the positioning cylinder 7-3 can be not limited, for example, its external cross-sectional profile can be square, triangular, circular, elliptical, etc., and the positioning cylinder 7-3 is constructed with an internal thread.

The first base 7 rises or falls at the same time under the transmission action of the thread, thereby realizing the angle adjustment of the pipeline in the horizontal plane and the height adjustment of the pipeline in the vertical direction. After the adjustment is completed, the third positioning part and the positioning cylinder 7-3 form a tight fit to constrain the angle of the pipeline in the horizontal plane and the height of the pipeline in the vertical direction.

[0040] Compared with the existing pipe supports, under the working condition that the horizontal variable and the vertical variable increase or decrease in proportion, the quick-assembly multi-degree-of-freedom stepless adjustment pipe support provided in the embodiment of the present application can realize the simultaneous adjustment of the angle of the pipe in the horizontal plane and the vertical height, which is easy to operate and has a relatively high adjustment efficiency; and the tight fit between the third positioning portion and the positioning cylinder 7-3 can simultaneously constrain the angle of the pipe in the horizontal plane and the vertical height, that is, it can prevent the second base 9 from accidentally rotating on the third base, thereby ensuring that the pipeline has a relatively stable service state.
