Description

Technical Field

[0001] The present application relates to the technical field of pipeline connection structures, and in particular to a pipeline quick connection structure. Background Art

[0002] At present, the connection methods between steel pipes are mainly threaded connection, welding connection, flange connection, clamp connection, etc. For larger-diameter transmission pipelines, welding connection or flange connection is usually used to ensure the pressure-bearing capacity of the pipeline. However, when it is necessary to connect two fixed-position pipelines, the welding connection method requires accurate measurement of the distance between the two pipelines, accurate cutting of steel pipe materials, and welding, which has low construction efficiency; the flange connection method also requires accurate cutting of steel pipe materials and welding of flanges, and then the use of a large number of bolts for fixing, which also has low construction efficiency. Utility Model Content

[0003] In order to improve the efficiency of connection construction between pipelines, the present application provides a pipeline quick connection structure.

[0004] A pipeline quick connection structure provided in this application adopts the following technical solution:

At the same time, the connecting pipe group is retractable and can adapt to the working conditions of different pipe body spacings, thereby increasing the application scope of the quick connection structure.

[0011] Optionally, the clamping assembly includes:

[0012] There are multiple clamping blocks, which are slidably connected to the mounting ring along the radial direction of the mounting ring and are used to abut the pipe body;

[0015] Each of the blocks slides against a combination of a first sliding wall, a transition sliding wall and a second sliding wall; when the block abuts against the second sliding wall, the distance from the center axis of the connecting ring is greater than the radius of the connecting ring.

[0016] By adopting the above technical solution, the worm can be rotated to drive the adjusting ring to rotate, so as to realize the movement of the clamping block in the radial direction and clamp or release the tube body. In the clamping state, due to the self-locking property between the worm and the adjusting ring, the adjusting ring will maintain its position and will not be easy to loosen.

[0017] Optionally, a sealing gasket is provided between the mounting ring and the end of the connecting ring close to the pipe opening of the pipe body.

[0021] Optionally, the clamping assembly further includes a spring disposed between the clamping block and the mounting ring, and the spring pushes the clamping block in a direction away from the tube body.

[0022] By adopting the above technical solution, when the clamping block faces the second sliding wall, the spring can maintain the clamping block in abutment with the second sliding wall, making it convenient for construction workers to put the installation ring onto the connecting ring.

[0023] Optionally, a limit block is provided at one end of the first sliding wall away from the transition sliding wall.

[0029] By adopting the above technical solution, the sliding connection between the first connecting tube and the second connecting tube can adapt to different tube body spacings, and the supporting member can press the first connecting tube and the second connecting tube against the mounting ring.

[0030] Optionally, the top support member includes:

[0031] An insert rod, one end of which is plugged into the insert ring, and the other end of which is provided with an external thread;

[0032] The threaded tube has one end threadedly connected to the insertion rod and the other end plugged into the second connecting pipe.

[0033] By adopting the above technical solution, the second connecting pipe and the plug-in ring are plugged into the two ends of the supporting member, so that the supporting member is not easily deviated from the working position.

[0045] There are two pipe bodies 1, and the pipe openings of the two pipe bodies 1 are coaxially opposite and spaced apart. A connecting ring 11 is welded outside the pipe opening of the pipe body 1, and the connecting ring 11 is flush with the pipe opening.

[0046] The mounting ring 2 is sleeved outside the connecting ring 11, and one end is provided with an opening for the connecting ring 11 to enter; a sealing gasket 5 is provided between the other end and the end of the connecting ring 11 close to the pipe opening of the pipe body 1, and the connecting ring 11 and the mounting ring 2 jointly clamp the sealing gasket 5. The inner diameter of the sealing gasket 5 and the inner diameter of the mounting ring 2 are both equal to the inner diameter of the pipe body 1. Each connecting ring 11 is correspondingly provided with a mounting ring 2 and a sealing gasket 5, and the openings of the two mounting rings 2 are opposite to each other.

[0047] Reference Figure 2 and Figure 3, each mounting ring 2 is provided with a set of clamping components 3, and the clamping components 3 include a clamping block 31, an adjusting ring 32, a worm 33 and a spring 34. The clamping block 31 is connected to the mounting ring 2 by sliding along the radial direction of the mounting ring 2, and the bottom end penetrates the mounting ring 2 inwardly. In the embodiment of the present application, there are eight clamping blocks 31, which are evenly distributed along the circumference of the mounting ring 2. One end of the clamping block 31 that penetrates the mounting ring 2 is provided with chamfers on both sides of the axial direction of the mounting ring 2. When the mounting ring 2 is sleeved on the connecting ring 11, the clamping block 31 moves toward the tube body 1, and the chamfered surface can squeeze and push the connecting ring 11 so that the connecting ring 11 can press the sealing gasket 5 more tightly. A limiting plate 311 is integrally formed on the side wall of the clamping block 31 away from the sealing gasket 5, and a spring 34 is provided between the limiting plate 311 and the mounting ring 2. The spring 34 can push the clamping block 31 in a direction away from the central axis of the mounting ring 2, so as to facilitate the sleeve of the mounting ring 2 on the connecting ring 11.
