Abstract
Description
Technical Field
[0001] This invention belongs to the field of track equipment technology, specifically a large-span prefabricated bridge support structure for rail transit electromechanical pipelines. Background Technology
[0002] In the fields of rail transit, large industrial plants, and public buildings, reliable support for electromechanical pipeline systems (including water supply and drainage, HVAC, fire protection, and electrical cable trays) is crucial to ensuring their safe and stable operation. Currently, the laying of such pipelines widely relies on traditional support and hanger systems. However, with the increasing demands for space utilization efficiency in modern engineering, pipeline layouts are becoming increasingly complex, spans are growing larger, and the weight of the pipelines they bear is increasing daily. Coupled with the continuous vibrations generated during rail transit operation, traditional support and hanger systems are gradually revealing many limitations.
[0003] First, existing traditional pipe supports and hangers mostly employ simple structures assembled from welded or bolted steel sections, often lacking in overall integrity and rigidity. Under conditions of large spans and heavy loads, such structures are prone to significant settlement and deformation due to insufficient strength or rigidity, leading to changes in pipeline slope, affecting the normal function of the system, and even causing structural safety issues. Second, most traditional pipe supports and hangers focus on vertical load-bearing while lacking effective lateral restraint and seismic resistance measures. When subjected to horizontal loads (such as seismic forces, equipment vibration, or thrust generated by pipeline thermal displacement), they are prone to lateral instability or displacement, exhibiting weak anti-sway capabilities and posing safety hazards.
[0004] Furthermore, the installation and adjustment process of existing pipe supports is usually quite cumbersome. Pipeline positioning and height adjustment often rely on manual experience and extensive on-site measurements, lacking a convenient and reliable fine-tuning mechanism. This results in low installation efficiency, difficulty in ensuring precise alignment of all pipelines, and challenges for later maintenance and pipeline expansion. In addition, the interoperability between the components of traditional pipe supports is poor, the load transfer path is singular, and stress concentration is significant. They fail to form a cohesive, load-bearing system, which means that material efficiency is not fully utilized. To meet load-bearing requirements, excessive material usage is often necessary, leading to poor economic efficiency.
[0005] Therefore, there is an urgent need for a new type of prefabricated bridge support structure that must have extremely high load-bearing capacity and overall rigidity to effectively resist deformation and vibration under heavy loads; at the same time, it should have good lateral stability and anti-sway performance, and be able to achieve quick and flexible installation and adjustment to overcome the above-mentioned defects of existing technologies. Summary of the Invention
[0006] The technical solution adopted in this invention is as follows: a large-span prefabricated bridge-type support structure for rail transit electromechanical pipelines, comprising:
[0007] Large-span prefabricated bridge-type support structure for rail transit electromechanical pipelines, including:
[0008] The two suspension rods are arranged in parallel.
[0009] A pull-down assembly is located on the outer wall of the suspension rod, wherein: the pull-down assembly includes a first I-beam, a pull-down cable, a first tension seat, a second tension seat, and a side cable. The first tension seat and the second tension seat are respectively fixedly installed on both sides of the outer wall of the two suspension rods. The two first I-beams are respectively installed on the upper sides of the suspension rods. One end of the pull-down cable is rotatably inserted into the outer wall of the first I-beam through a bracket, and the other end of the pull-down cable is rotatably inserted into the inner wall of the first tension seat through a bracket. One end of the side cable is rotatably inserted into the inner wall of the second tension seat through a bracket.
[0010] A hanger assembly is located on the outer wall of the suspension rod, wherein the hanger assembly is used to suspend and limit the electromechanical pipeline;
[0011] A fixing component is provided on the outer wall of the suspension rod, wherein the fixing component is used to support and laterally fix the suspension rod.
[0012] Furthermore, the hanger assembly includes a support frame, a reinforcing frame, a limiting cable, and a constraint ring. The two support frames are respectively fixed to the bottom sides of the outer wall of the suspension rod by bolts. The reinforcing frame is sleeved on the bottom sides of the support frame. The two ends of the limiting cable are respectively rotatably sleeved on the outer sides of the reinforcing frame. The other end of the side cable is rotatably inserted into the outer sides of the reinforcing frame.
[0013] Furthermore, the constraint ring is fixed to the outer wall of the support frame by bolts.
[0014] Furthermore, the fixing assembly includes a second I-beam, an auxiliary frame, a dispersing rod, a reinforcing rod, a support rod, a limiting sleeve, an upper clamp, an upper clamp, a lower clamp, and a lower clamp.
[0015] Furthermore, the two second I-beams are attached to the bottom sides of the outer wall of the suspension rod, the dispersion rod is fixedly installed on the top outer wall of the auxiliary frame, the limiting sleeve is slidably embedded in the inner walls of both ends of the support rod, and the limiting sleeve is embedded in the recess on one side of the inner wall of the suspension rod.
[0016] Furthermore, the upper clamp is sleeved on the outer wall of the suspension rod, and the upper clamp is fixedly set on the bottom outer wall of the upper clamp by a nut. Both upper clamps have teeth on their outer walls that engage with the outer walls of the second I-beam.
[0017] Furthermore, the lower clamp is sleeved on the outer walls of both ends of the dispersion rod, and the lower clamp is fixedly set on the top outer wall of the lower clamp by a nut. The outer walls of the two lower clamps are provided with clamping teeth that engage with the outer walls of the second I-beams on both sides.
[0018] Furthermore, three suspension cables are fixed at equal intervals on both sides of the bottom of the outer wall of the two suspension rods by bolts, and multiple force-bearing rods are sleeved on the outer wall of each suspension cable.
[0019] Furthermore, two first bolts are fitted at the center of one end of the outer wall of the support rod, and both first bolts penetrate into the inner wall of the limiting sleeve. A second bolt is embedded at the center of the other end of the outer wall of each limiting sleeve, and the second bolt penetrates through the outer wall of the fixed suspension rod through a nut.
[0020] Furthermore, each of the reinforcing rods is fitted with a reinforcing head at both ends, and every two reinforcing heads form a group. Each group of reinforcing heads is fixed with a fixing frame and an angle frame by bolts. Each fixing frame is fixed to the outer wall of the auxiliary frame by a bracket, and the angle frame is fixed to the external fixing surface by expansion screws.
[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0022] (1) In this invention, the pull-down assembly, through the cooperation of the first I-beam, the pull-down cable, the first tension seat, the second tension seat and the side cable, effectively transfers the vertical load borne by the suspension rod to the main structure of the building, greatly enhancing the rigidity and stability of the overall structure, effectively preventing the support and hanger from sinking or shifting laterally due to large span and heavy load, and ensuring the long-term safety and stability of the pipeline system.
[0023] (2) In this invention, the hanger assembly, through the design of support frame, reinforcement frame, limit cable and constraint ring, not only provides reliable suspension support for electromechanical pipelines, but its unique limit cable and reinforcement frame structure also enhances the lateral stability of the support frame, and forms a linkage with the side cable of the pull-down assembly to jointly resist the horizontal force. Multiple suspension cables and adjustable height force rods work together to make the pipeline layout and adjustment more flexible and convenient, and facilitate installation and subsequent maintenance.
[0024] (3) In this invention, the fixing component uses a series of components such as the second I-beam, auxiliary frame, dispersion rod, reinforcing rod, upper clamp, upper clamp, lower clamp and lower clamp to firmly lock and support the suspension rod on the second I-beam. The tooth design of the upper clamp and lower clamp ensures that the connection is firm and reliable, effectively preventing loosening. The dispersion rod and the reinforcing rod distributed at an acute angle further disperse and transmit the load, and are fixed to the external building foundation through the angle frame, forming a strong lateral support system. Together with the pull-down component and the hanger component, it constitutes a highly stable, high load-bearing and good deformation resistance whole.
[0025] (4) In this invention, the design of each component not only plays a key role, but more importantly, they form an efficient linkage and complementarity, ultimately realizing a prefabricated support structure with strong load-bearing capacity, excellent seismic performance, convenient installation and adjustment, and suitable for large-span scenarios such as rail transit.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0034] Example 1
[0035] Reference Figure 1 - Figure 6 The rail transit electromechanical pipeline large-span prefabricated bridge support structure includes: a suspension rod 1, two suspension rods 1 arranged in parallel, and a pull-down assembly located on the outer wall of the suspension rod 1. The pull-down assembly includes a first I-beam 2, a pull-down cable 201, a first tension seat 101, a second tension seat 102, and a side cable 103. The first tension seat 101 and the second tension seat 102 are respectively fixedly installed on both sides of the outer wall of the two suspension rods 1. The two first I-beams 2 are respectively located on the upper sides of the suspension rod 1. One end of the pull-down cable 201 is... The first I-beam 2 is rotatably inserted into the outer wall of the first I-beam 2 via the bracket. The other end of the pull cable 201 is rotatably inserted into the inner wall of the first tension seat 101 via the bracket. One end of the side pull cable 103 is rotatably inserted into the inner wall of the second tension seat 102 via the bracket. The hanger assembly is located on the outer wall of the suspension rod 1. The hanger assembly is used to suspend and limit the electromechanical pipeline. The fixing assembly is located on the outer wall of the suspension rod 1. The fixing assembly is used to support and laterally fix the suspension rod 1. First, the first I-beam 2 and the second I-beam 3 are connected. After being positioned at the designated work location, two suspension rods 1 were laid. Mounting holes were pre-drilled on the suspension rods 1 to reduce their weight while ensuring structural integrity, facilitating installation and bolt fixing. Then, the auxiliary frame 4, suspension cable 5, load-bearing rod 6, and support frame 7 were conveniently deployed to the bottom of the suspension rods 1. Finally, the side cable 103 and down cable 201 were installed. The two support frames 7 were further restrained using the limiting cable 9. After initial fixing, the two reinforcing rods 11 were spread out at an acute angle. Angle bracket 404 and expansion bolts are used to fix one end of the reinforcing rod 11. At this time, the electromechanical pipeline is passed through the auxiliary frame 4, suspension cable 5, force-bearing rod 6 and support frame 7 in sequence. By adjusting the height of the force-bearing frame at the suspension cable 5, it is convenient to initially lift and lower some electromechanical pipelines, and to facilitate limiting and fixing. In the subsequent work process, the first I-beam 2 and the pull cable 201 can ensure the overall structural strength of the suspension rod 1 and prevent it from sinking and shifting.

Two second I-beams 3 are attached to the bottom sides of the outer wall of the suspension rod 1. The dispersion rod 401 is fixed to the top sides of the outer wall of the auxiliary frame 4. The limiting sleeve 13 is slidably embedded in the inner walls of both ends of the support rod 12. The limiting sleeve 13 is embedded in the recess on one side of the inner wall of the suspension rod 1. The limiting sleeve 13 can ensure the continuous limiting of the support rod 12 and structural reinforcement. The upper clamp 16 is sleeved on the outer wall of the suspension rod 1. The upper clamp 17 is fixedly set on the bottom outer wall of the upper clamp 16 by a nut. The outer walls of the two upper clamps 17 are provided with teeth to engage with the outer sides of the second I-shaped steel 3. The lower clamp 18 is sleeved on the outer walls of both ends of the dispersion rod 401. The lower clamp 19 is fixedly set on the top outer wall of the lower clamp 18 by a nut. The outer walls of the two lower clamps 19 are provided with teeth to engage with the outer sides of the second I-shaped steel 3. The upper clamp 17 and the lower clamp 19 can ensure the stable engagement of the second I-shaped steel 3. The teeth can ensure stability.
[0037] Reference Figure 1 - Figure 6 Three suspension cables 5 are fixedly installed at equal intervals on both sides of the bottom of the outer wall of the two suspension rods 1 by bolts. Each suspension cable 5 has multiple force-bearing rods 6 on its outer wall. The suspension cables 5 can be used as additional deployment parts to increase the number and distribute the supporting force of the auxiliary frame 4 and the support frame 7, so as to support the electromechanical pipeline with large mass. Two first bolts 14 are installed at the center of the outer wall of one end of the support rod 12, and both first bolts 14 penetrate into the inner wall of the limiting sleeve 13. A second bolt 15 is embedded at the center of the outer wall of the other end of each limiting sleeve 13, and the second bolt 15 is fixed to the outer wall of the suspension rod 1 by a nut. Each reinforcing rod 11 has a reinforcing head 402 installed at both ends. Every two reinforcing heads 402 form a group. Each group of reinforcing heads 402 is fixed with a fixing frame 403 and an angle frame 404 by bolts. Each fixing frame 403 is fixed to the outer wall of the auxiliary frame 4 by a bracket, and the angle frame 404 is fixed to the external fixing surface by expansion screws.
[0038] Working principle:
[0039] First, the first I-beam 2 and the second I-beam 3 are deployed to the designated working positions. Then, two suspension rods 1 are laid, with mounting holes pre-drilled on them. While ensuring structural integrity, the weight of the suspension rods 1 is reduced to facilitate installation and bolt fixing. Next, the auxiliary frame 4, suspension cable 5, load-bearing rod 6, and support frame 7 are deployed to the bottom of the suspension rod 1. Finally, the side cable 103 and the down cable 201 are installed. The two support frames 7 are further restrained using the limiting cable 9. After initial fixing, the two reinforcing rods 11 are dispersed. Distributed in an acute-angle shape, the angle bracket 404 and expansion bolts are used to fix one end of the reinforcing rod 11. At this time, the electromechanical pipelines are passed through the auxiliary frame 4, suspension cable 5, force-bearing rod 6 and support frame 7 in sequence. By adjusting the height of the force-bearing frame at the suspension cable 5, it is convenient to initially lift and lower some electromechanical pipelines, and to facilitate limiting and fixing. In the subsequent work process, the first I-beam 2 and the pull cable 201 can ensure the overall structural strength of the suspension rod 1 and prevent it from sinking and shifting. The side pull cable 103 can ensure the stability of the support frame 7 and ensure the distribution of force.
