Description

Technical Field

[0001] The utility model relates to the technical field of pipeline protection equipment, in particular to a detachable bracket for a pipeline flange elbow. Background Art

[0002] With the rapid development of the construction industry, society has higher and higher requirements for the quality of buildings. There are various equipment rooms in large buildings. Flexible joints are usually installed at the connection between equipment and pipelines. The flexible joint alleviates the resonance between the equipment and the pipeline and protects the pipeline. At the same time, the other end of the flexible joint is flange-connected to the pipeline and equipped with a groove elbow, which is the weak link of the pipeline.

[0003] In the prior art, when supporting a pipeline, a construction method of fixing the vertical pipeline on the side is usually adopted. In the past, after fixing the vertical pipeline on the side, when the pipeline is pressed down by gravity, the pipeline support is easily pulled downward, thereby damaging the pipeline support. Utility Model Content

[0004] The utility model aims to solve the problems raised in the background technology and provides a detachable bracket for a pipeline flange elbow.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model provides a detachable bracket for a pipeline flange elbow. Through its structural design, when supporting the pipeline, the base is fixed beside the ground of the flange elbow, and then the flange at the flange elbow is disassembled and assembled, and the height of the clamping device is adjusted according to the height of the supporting position. When adjusting the height, the screwing plate located on the connecting rod is rotated, and the rotation of the screwing plate drives the arc block to make a circular motion. The arc block moves and pushes the push block to slide toward the center of the connecting rod on the fixed plate through the arc inclined surface. The push block slides toward the center and drives the slider to slide toward the center. The movement of the slider drives the clamping block to move toward the center. The clamping block moves and is separated from the rack. At this time, moving the connecting rod can drive the height of the extension rod to change, and the change in the height of the extension rod drives the change in the height of the support frame. The change in the height of the support frame makes the height of the clamping device correspond to the position that needs to be supported. After the height is determined, the screwing plate is loosened, and the spring drives the clamping block to reset. The clamping block resets and re-engages with the rack to fix the height of the extension rod. Finally, the clamping device is placed between the pipeline and the flange of the flexible software, and the fixing bolts are tightened so that the clamping device and the flange cannot shake. At this point, the utility model is installed. When the pipeline needs to be repaired or parts replaced in the later stage, the utility model can be disassembled by the clamping device, which is convenient for the replacement of pipeline parts. Compared with the prior art, the utility model uses the clamping device as the supporting point of the overall bracket to firmly fix the flange pipeline on the soft connection, support the pipeline from the bottom, and flexibly avoid the construction method of fixing the vertical pipeline on the side, which truly plays the role of supporting and fixing. At the same time, the bracket is a detachable bracket, which is convenient for the disassembly and replacement of the bracket connection in the later stage, and provides great convenience for the later pipeline maintenance.
