Description

Technical Field

[0001] This utility model relates to the field of pipeline fixing technology, specifically a pipeline support for nuclear power plants. Background Technology

[0002] The piping in nuclear power plants is extremely complex, with large pipe sizes, heavy loads, and high temperatures, pressures, and velocities of the fluids it transports. To ensure the integrity and availability of the piping under special conditions such as earthquakes or accidents, these pipes are usually fixed with rigid supports.

[0003] After installation, the distance between the pipe and the wall of the existing pipe fixing bracket cannot be adjusted, making it difficult to adjust according to the on-site installation requirements. Therefore, some people have proposed an adjustable pipe fixing bracket, such as the Chinese utility model patent with announcement number CN219177088U, which specifically discloses a pipe fixing bracket for thermal equipment in nuclear power plants.

[0004] However, in actual use, it has been found that the pipe fixing supports used in the aforementioned nuclear power plants have a fixed height after the pipes are installed, which makes it difficult to adapt to minor errors in pipe manufacturing or on-site installation, such as pipe length or flange connection deviations. This may lead to forced assembly, and if the pipe layout needs to be adjusted, such as adding branches or equipment, the fixing supports may not be able to adapt to the height requirements of the new path.

[0028] Furthermore, the frame 1 includes a first support plate 101, a second support plate 102, and a reinforcing plate 103. The second support plate 102 is vertically fixed to the top of the first support plate 101, and the reinforcing plate 103 is fixed between the first support plate 101 and the second support plate 102. A first sliding groove 1021 is provided above the second support plate 102, and the adjustment assembly 2 is disposed below the second support plate 102. The reinforcing plate enhances the rigidity of the frame 1.

[0029] Furthermore, the adjusting assembly 2 includes a first lead screw 201 and a first slider 202. The first lead screw 201 is parallel to the second support plate 102 and is rotatably connected to the first support plate 101. The first slider 202 is threadedly connected to the first lead screw 201. By rotating the first lead screw 201, the first slider 202 is driven to move back and forth, thereby changing the fixed position of the pipe.

[0030] Furthermore, the lifting assembly 3 includes a vertical cylinder 301, a second lead screw 302, a second slider 303, and a support rod 304. The vertical cylinder 301 is fixed on the first slider 202 and slidably connected in the first slide groove 1021. The second lead screw 302 is rotatably connected in the vertical cylinder 301. The second slider 303 is threadedly connected to the second lead screw 302. A through second slide groove 3011 is provided on the side of the vertical cylinder 301. The support rod 304 is fixed on the second slider 303 and passes through the second slide groove 3011. The spring damping shock absorber 4 is fixed to the top of the support rod 304.

[0031] By rotating the second lead screw 302, the second lead screw 302 drives the second slider 303 to move up and down, thereby causing the second slider 303 to drive the pipe clamping assembly 5 that fixes the pipe to move up and down, changing the height of the pipe and realizing height adjustment.

[0032] Furthermore, the first support plate 101 is provided with a plurality of mounting holes 1011, which are used to fix the bracket to the wall with self-tapping screws.

[0033] Furthermore, a first knob 2011 is fixed to the end of the first lead screw 201. The first knob 2011 is mainly for facilitating the rotation of the first lead screw 201.

[0034] Furthermore, the top end of the second lead screw 302 passes through the vertical cylinder 301 and is fixed with a second knob 3021. The second knob 3021 is mainly provided to facilitate the rotation of the second lead screw 302.

[0035] Furthermore, the pipe clamping assembly 5 includes a fixing plate 501, a first fixing ring 502, and a second fixing ring 503. The fixing plate 501 is fixed to the top of the spring damping shock absorber 4, the first fixing ring 502 is fixed above the fixing plate 501, and the second fixing ring 503 is positioned above the first fixing ring 502. Both the first fixing ring 502 and the second fixing ring 503 are arc-shaped to fit the pipe, and are clamped onto the pipe for fixation by the first fixing ring 502 and the second fixing ring 503.

[0036] Furthermore, a first locking plate 5021 is fixed to the side of the first fixing ring 502, and a second locking plate 5031 is fixed to the side of the second fixing ring 503. The first locking plate 5021 and the second locking plate 5031 are fixed together by bolts, thereby realizing the locking and fixing of the first fixing ring 502 and the second fixing ring 503.

[0037] In summary, during use, rotating the first knob 2011 drives the first lead screw 201 to rotate, causing the first slider 202 to move back and forth along the first lead screw 201, thereby driving the entire lifting assembly 3 to move horizontally and adjust the position of the pipe in the horizontal direction. Rotating the second knob 3021 drives the second lead screw 302 to rotate, causing the second slider 303 to move up and down within the vertical cylinder 301, and driving the pipe clamping assembly 5 to rise and fall via the support rod 304, achieving precise adjustment of the pipe height. When the pipe vibrates or expands and contracts due to thermal expansion and contraction, the spring damping shock absorber 4 absorbs the impact energy, reducing the vibration transmitted to the support and wall, and improving system stability. The first fixing ring 502 and the second fixing ring 503 are locked together with bolts to clamp the pipe, ensuring a stable fixation and adapting to different pipe diameters.
