Description

Technical Field

[0001] The utility model relates to the technical field of pipeline supports, in particular to an adjustable fixing support for underground power house pipelines. Background Art

[0002] In recent years, with the rapid development of renewable energy, pumped-storage technology has played an increasingly important role in the power system. This technology can not only effectively balance power supply and demand, but also provide economic benefits in the peak-valley electricity price difference. However, with the continuous expansion of the scale of pumped-storage projects, the layout of oil, gas, and water system pipelines in underground power houses has become increasingly complex. In these systems, pipelines are often laid along the wall, and the layout forms of their supports and hangers are diverse.

[0003] During the actual operation process, the continuous transportation of fluids will cause large vibrations in the pipelines, which not only affect the stability of the pipelines, but may also cause damage to surrounding equipment. Traditional pipeline fixing supports mainly adopt welding forms. This connection method generates large stresses at the joints, and long-term vibrations will cause tearing at the welded parts, thus bringing potential safety hazards. In addition, traditional fixing supports do not have adjustability. Adjusting the installation position can only be achieved by replacing steel pipes of different lengths, resulting in low installation efficiency, inability to achieve reuse, and heavy weight and inconvenient installation.

[0004] Therefore, it is urgent to develop an adjustable fixing support for underground power house pipelines to overcome the deficiencies of the prior art. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies of the prior art and provide an adjustable fixing support for underground power house pipelines to improve the safety and installation adjustment efficiency of the fixing support for pipelines.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Preferably, one end of the base support is fixed on the wall through anchor bolts, and the other end is a U-shaped steel. Observation holes and weight reduction grooves are provided on the vertical surface of the U-shaped steel end, and a limiting hole is provided on the horizontal surface of the U-shaped steel end. The limiting hole is connected to the heavy-duty lock, and tooth grooves are provided around the limiting hole.

[0009] Preferably, the cross brace square tube is a U-shaped steel. One end of the cross brace square tube is inserted into the bottom support. A number of equally spaced square holes are provided on the vertical surface of the cross brace square tube, and a number of fixing holes are provided on the horizontal plane of the U-shaped steel end.

[0010] Preferably, the heavy-duty lock includes a locking bolt sleeved with a limit hole sleeve and a locking gasket provided between the locking bolt and the bottom support. One end of the locking gasket in contact with the bottom support is provided with a tooth nail that tightly meshes with the tooth groove, and the end of the locking bolt presses on the horizontal plane of the cross brace square tube.

[0011] Preferably, the square tube connector includes a fixed seat and an adapter block rotatably connected to the fixed seat through a rotating shaft. A number of connection holes are provided on the adapter block.

[0012] Preferably, a gasket is provided between the pipe clamp and the pipeline.

[0013] Preferably, an end cap is sleeved on the empty end of the cross brace square tube.

[0014] The adjustable fixing bracket for the pipeline in the underground power house disclosed by the present utility model has the following beneficial effects.

[0015] First, the device of the present utility model controls the overlapping length of the cross brace square tube and the bottom support through the heavy-duty lock, thereby realizing the adjustment of the distance between the pipe clamp and the wall.

[0016] Second, the tooth nail at one end of the locking gasket in contact with the bottom support in the heavy-duty lock of the present utility model tightly meshes with the tooth groove provided around the limit hole, enhancing the locking ability of the heavy-duty lock. The main components are all made of U-shaped steel structure, which effectively reduces the weight of the bracket while ensuring the strength, reducing the construction difficulty and the labor intensity during installation.

[0017] Third, through the sequential connection of the cross brace square tube, the square tube connector, the diagonal brace square tube, the square tube connector, and the wall, the present utility model effectively supports the cross brace square tube, enhancing the stability of the pipeline bracket. The structure of the present utility model is simple and light, and can be disassembled to easily realize the reuse of the bracket. BRIEF DESCRIPTION OF THE DRAWINGS

Embodiment

[0024] The present invention discloses an adjustable fixing bracket for underground factory building pipelines in the scenario of fixing underground factory building pipelines.

[0025] Refer to Figure 1 , an adjustable fixing bracket for underground factory building pipelines, including a bottom support 2 fixed on the wall 10 through an anchor bolt 1, a horizontal brace square pipe 3 slidably connected to the bottom support 2, a heavy-duty lock 4 installed on the horizontal brace square pipe 3 through a locking bolt 401 to limit the relative sliding of the horizontal brace square pipe 3 and the bottom support 2, a square pipe connector 5 with one end connected to the bottom of the horizontal brace square pipe 3 through a fixing bolt 505 and the other end sleeved with a diagonal brace square pipe 6, the other end of the diagonal brace square pipe 6 is connected to the wall 10 through another square pipe connector 5, and the other square pipe connector 5 is fixed on the wall 10 through an anchor bolt 1 and is fixed below the bottom support 2. A connecting screw 8 is connected above the horizontal brace square pipe 3 to a pipe clamp 7, and both ends of the pipe clamp 7 are locked on the connecting screw 8 with nuts 9. The connecting screw 8 is connected to the horizontal brace square pipe 3 through the nuts 9. The pipe clamp 7 is of the PI type and is selected according to the specification model of the pipeline 11.

[0026] In order to prevent electrochemical reaction, a gasket 701 is arranged between the pipeline 11 and the pipe clamp 7. The width of the gasket 701 is greater than or equal to the width of the supporting surface of the pipe clamp 7, and the surface is flat without protrusions.

[0027] As Figure 1 and Figure 2 shown, one end of the base support 2 is fixed to the wall body 10 by an anchor bolt 1, and the other end is a U-shaped steel. A kidney-shaped observation hole 204 and a weight reduction groove 203 are provided on the vertical surface of the U-shaped steel end. A limit hole 201 is provided on the horizontal surface of the U-shaped steel end. The limit hole 201 is connected to the heavy-duty lock 4, and a tooth groove 202 is provided around the limit hole 201. The heavy-duty lock 4 includes a locking bolt 401 sleeved with the limit hole 201 and a locking gasket 402 provided between the locking bolt 401 and the base support 2. One end of the locking gasket 402 in contact with the base support 2 is provided with a tooth nail that meshes tightly with the tooth groove 202. The end of the locking bolt 401 presses on the horizontal surface of the cross brace square tube 3. Through the tight meshing of the tooth nail at one end of the locking gasket 402 in contact with the base support 2 in the heavy-duty lock 4 with the tooth groove 202 provided around the limit hole 201, the locking ability of the heavy-duty lock 4 is enhanced.

[0028] As Figure 1 shown, the cross brace square tube 3 is a U-shaped steel. One end of the cross brace square tube 3 is inserted into the base support 2. A number of equally spaced square holes 301 are provided on the vertical surface of the cross brace square tube 3, so as to estimate the distance between the pipe clamp 7 and the wall surface through the kidney-shaped observation hole 204 provided on the base support 2. A number of fixing holes 302 are provided on the horizontal surface of the U-shaped steel end. The fixing holes 302 on the upper horizontal section are sleeved with the connecting screw 8. The connecting screw 8 is connected to the cross brace square tube 3 through a nut 9. A spring washer is placed between the nut 9 and the cross brace square tube 3, so as to stably install the pipe clamp 7. The connection position adopts connection methods such as bolts and nuts, which greatly reduces the stress concentration of the vibration of the pipeline 11 on the support and the welding part, and avoids the tearing phenomenon that may occur in the traditional welded support during long-term vibration. By controlling the overlapping length of the cross brace square tube 3 and the base support 2 through the heavy-duty lock 4, the distance of the pipe clamp 7 from the wall is adjusted, and the position of the support can be quickly adjusted according to the on-site requirements, without the need to cut the steel pipe or perform cumbersome welding operations like the traditional support, thus greatly improving the installation efficiency. The main components all adopt U-shaped steel structures, which effectively reduce the weight of the support while ensuring the strength, and reduce the construction difficulty and labor intensity during installation.

[0029] As Figure 3 shown, the square tube connector 5 includes a fixed seat 501 and an adapter block 503 rotatably connected to the fixed seat 501 through a rotating shaft 502. A number of connection holes 504 are provided on the adapter block 503. When the connection holes 504 are aligned with the openings on the inclined brace square tube 6, they are fixedly connected by bolts. Through the sequential connection of the cross brace square tube 3, one square tube connector 5, the inclined brace square tube 6, the other square tube connector 5, and the wall body 10, an effective support is formed for the cross brace square tube 3, and the stability of the pipeline 11 support can be enhanced.

[0030] In this embodiment, in order to ensure aesthetics, an end cap 12 is sleeved on the empty end of the cross brace square tube 3.

[0031] In this embodiment, the anchor bolt 1 is of model M12, with a length of 25 cm.
