Description

Technical Field

[0001] This utility model relates to the field of underground pipeline installation, specifically a suspension support for underground tunnel pipelines. Background Technology

[0002] Underground passages, as a core component of urban infrastructure, are widely used in subways, tunnels, and utility pipeline systems. They are mainly used for personnel passage, vehicle transportation, or medium delivery (such as water, electricity, and gas pipelines). These passages are located in complex environments with limited space and need to withstand high vibration loads (such as earthquakes or mechanical operation). Therefore, the pipeline installation must be stable and reliable. The pipelines perform critical functions in the passages, such as water supply, drainage, or cable protection. Their fixation relies on suspension support systems to avoid displacement, leakage, or safety accidents.

[0003] Traditional suspension supports provide pipe support using simple clamps and fixing rods, often employing fixed-size clamps (such as single clamps or bolts). This makes them unsuitable for the diverse pipe diameters found in underground tunnels, leading to frequent replacements of specialized clamps or custom supports during installation, increasing inventory costs and construction time.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0015] like Figures 1 to 3 An underground passage pipe suspension support includes a set of hangers 5, with a main fixing plate 2 at the top of the hangers 5. The main fixing plate 2 is installed on the top 1 of the underground passage by expansion bolts. A hanging plate 8 is suspended at the bottom of the set of hangers 5, and multiple sets of clamping components 9 are provided on the hanging plate 8.

[0016] The clamping assembly 9 includes a gantry frame 11 disposed on the upper surface of the hanging plate 8. The lower end of the gantry frame 11 is rotatably connected to a screw 17 and a light shaft 15. The screw 17 and the light shaft 15 are arranged in parallel. One end of the screw 17 is provided with a first handle 18.

[0017] The screw spool 17 is symmetrically provided with a forward spiral thread and a reverse spiral thread, and a first clamping plate 14 and a second clamping plate 16 are respectively threaded to the forward spiral thread and the reverse spiral thread. The first clamping plate 14 and the second clamping plate 16 are slidably connected to the optical shaft 15. The adjacent end faces of the first clamping plate 14 and the second clamping plate 16 are symmetrically provided with inclined slopes, and the two slopes form a figure-eight clamping space for supporting the guide rail 19.

[0018] Rotating the first handle 18 drives the screw 17 to rotate. The two threads on the screw 17 cooperate with the two clamping plates to control the distance between the first clamping plate 14 and the second clamping plate 16, so as to clamp and support pipes 19 of different diameters.

[0019] To further improve the stability of the clamping support pipe 19, a clamping assembly is provided at the top of the gantry 11 for pressing down the pipe 19 supported in the clamping space.

[0020] The clamping assembly specifically includes a first screw 24 that runs vertically through the gantry frame 11 and is threadedly connected to the gantry frame 11. The top of the first screw 24 is provided with a second handle 22. The bottom of the first screw 24 is rotatably connected to a pressure plate 20 for pressing down the pipe 19. The top of the pressure plate 20 is also provided with a guide rod 21 that is vertically slidably connected to the top of the gantry frame 11.

[0021] By rotating the second handle 22, the first screw 24 is driven to rotate, thereby driving the pressure plate 20 to move downward and press down to clamp the pipe 19 supported in the space, further fixing the pipe 19.

[0022] This utility model enables the bracket to automatically adapt to pipes 19 of different diameters through the synergistic action of the clamping component 9 and the pressing component, without the need to replace the corresponding size special clamps. This design reduces customization requirements, improves versatility, and reduces inventory costs, and is especially suitable for the diverse pipe 19 layouts in underground passages. Example 2

The diagonal bracing assembly includes a diagonal brace 4 hinged to the outer side of the hanger 5. The free end of the diagonal brace 4 is hinged to an auxiliary fixing plate 3 for connecting to the top of the underground passage 1.

[0024] The hanger 5 and the hanging plate 8 are suspended and connected by the second screw 6. Specifically, the bottom of the second screw 6 is connected to the hanging plate 8, and the bottom of the hanger 5 is provided with a through hole corresponding to the position of the second screw 6. The upper end of the second screw 6 passes through the through hole and is connected to the limit nut 7.

[0025] The height of the hanging plate 8 can be finely adjusted by rotating the limit nut 7, thereby finely adjusting the height of the pipe 19. Workers can move the hanging plate 8 up and down by rotating the limit nut 7 without disassembling the bracket or using additional tools. This design improves installation flexibility and saves time. Fine-tuning the height can avoid leakage or stress concentration caused by height errors, making it particularly suitable for complex elevation environments in underground passages. Example 3
