Description

Technical Field

[0001] The present application relates to the field of bridge wiring construction, and in particular to an electrical bridge pipeline installation construction method. Background Art

[0002] During the installation of electrical pipelines inside a building, it is usually necessary to first support a bridge at the bottom of the ceiling, and then lay the electrical pipelines in the bridge, using the bridge to store, organize, wrap and protect the electrical pipelines.

[0003] At present, the bridge is mainly installed under the ceiling by hanging it with several hangers. Figure 1 The hanger includes a support rod 11 and hangers 12 vertically arranged at both ends of the support rod 11; the support rod 11 is located at the bottom of the bridge frame 1 to support the bridge frame 1, and the top ends of the hangers 12 at both ends of the support rod 11 are fixed to the ceiling of the building through expansion screws.

[0004] Regarding the above-mentioned related technologies, due to the limitations of the hangers on both sides of the bridge, when laying electrical pipelines into the bridge, it is currently necessary to pull them from one end of the bridge to the other end of the bridge. During specific construction, it is necessary to lay out several pipeline traction points along the bridge and deploy corresponding construction personnel. When laying the pipelines, the construction personnel at each traction point cooperate to pull the electrical pipelines into the bridge to complete the laying and installation of the pipelines in the bridge. The above-mentioned electrical pipeline laying and installation method is not only difficult to operate, but also has low installation efficiency. It also requires more construction personnel to perform high-altitude operations, which poses certain safety hazards; therefore, there is room for improvement. Summary of the invention

[0005] In order to facilitate the laying and installation of electrical pipelines in a bridge, the present application provides an electrical bridge pipeline installation construction method.

[0006] The present application provides an electrical bridge pipeline installation construction method, which adopts the following technical solution: An electrical bridge pipeline installation construction method comprises the following steps: S1: Threading preparation: Move the traction trolley to the starting end of the bridge; the traction trolley is provided with a connection part for connecting the pipeline; S2: Pipeline connection: connect the pipeline to be installed with the connection part on the traction trolley; S3: Pipeline traction: The pipeline is pulled into the bridge by moving the traction trolley along the bridge; S4: Disconnect: Disconnect the connection between the traction trolley connection part and the pipeline.

[0007] By adopting the above technical solution, when laying the pipeline on the bridge, the pipeline to be laid is connected to the connecting part on the traction trolley, and then the traction trolley is moved along the bridge. The traction trolley is used to pull the pipeline to be laid from the starting end of the bridge to the end of the bridge to complete the pipeline laying. Compared with the traditional laying method of dragging the pipeline into the bridge by several construction workers, it is beneficial to reduce the difficulty of laying the pipeline in the bridge, improve the overall pipeline laying construction efficiency, and effectively reduce the safety hazards caused by manual high-altitude operations.

[0008] Preferably, the connecting portion comprises a connecting plate vertically supported on the traction trolley, the connecting plate is connected with a plurality of connecting pipes, the connecting pipes are used for pipelines to pass through, and locking bolts are threadedly passed through the outer circumference of the connecting pipes; In step S2, the end of the pipeline to be laid is inserted into the corresponding connecting pipe, and the locking bolt is tightened to connect the pipeline to the traction trolley.

[0009] By adopting the above technical solution, when connecting the pipeline to be laid with the traction trolley, after inserting the pipeline into the corresponding connecting roller on the connecting plate, the locking bolt is screwed to tighten the locking bolt and the pipeline in the connecting pipe at this time, so that the pipeline to be laid and the traction trolley can be firmly connected, so that the pipeline can be pulled to the end of the bridge frame by the traction trolley later. When it is necessary to disconnect the traction trolley from the pipeline, the locking bolt is loosened and the end of the pipeline is pulled out of the connecting pipe to complete the separation between the pipeline and the traction trolley.

[0010] Preferably, a scraper plate is also supported at the front end of the traction trolley, and when the traction trolley is located in the bridge frame, the bottom of the scraper plate is arranged to abut against the inner wall of the bottom of the bridge frame.

[0011] By adopting the above technical solution, when the bridge is installed at the bottom of the building ceiling through the hanger, some parts left when installing the hanger and debris such as gravel generated when drilling are likely to accumulate and remain in the bridge, which is likely to interfere with the subsequent pipeline layout. By supporting a scraper plate at the front end of the traction trolley, the subsequent traction trolley can push the debris such as gravel and metal parts remaining in the bridge to the end of the bridge through the scraper plate at the front end of itself when moving along the bridge, reducing the accumulation of debris in the bridge, which is conducive to reducing the interference and wear of the subsequent debris in the pipeline traction process.

[0012] Preferably, in step S1, before the traction trolley is moved to the starting end of the bridge frame, an auxiliary support mechanism is installed at the starting end of the bridge frame; The auxiliary support mechanism comprises a support frame, which can be sleeved on the bridge frame, and a main support is arranged at one end of the support frame, and a support roller is horizontally rotatably connected to the main support, and the support roller is used to support the pipeline; In step S1, when installing the auxiliary support mechanism, the support frame is sleeved on the end of the starting section of the bridge frame.

[0013] By adopting the above technical solution, an auxiliary support mechanism is installed at the starting end of the bridge, and the pipeline can be subsequently laid on the support rollers. When the pipeline is pulled into the bridge by the traction trolley, the support rollers rotate accordingly, and the support rollers are used to support and limit the pipeline to limit the contact between the pipeline and the edge of the starting end of the bridge, thereby avoiding the situation where the pipeline's own surface is easily worn due to friction with the end edge of the starting end of the bridge during the traction process.

[0014] Preferably, a secondary support is further provided at one end of the support frame away from the bridge frame, and a limit roller is horizontally rotatably connected to the secondary support, and a conveying gap for the pipeline to pass through is reserved between the limit roller and the support roller; In step S1, before connecting the pipeline to the traction trolley, the pipeline is passed through the conveying gap between the supporting roller and the limiting roller.

[0015] By adopting the above technical solution, the support roller and the limiting roller are used to clamp and limit the pipelines in the pulling process, so that the pipeline segments entering the bridge can be kept relatively flat as much as possible, and the situation of the pipeline segments entering the bridge being entangled due to pipeline bending or bulging is reduced, which is conducive to the neat layout of the pipelines in the bridge.

[0016] Preferably, the main support is provided with a main driving component for driving the supporting roller to rotate, and the auxiliary support is provided with an auxiliary driving component for driving the limiting roller to rotate.

[0017] By adopting the above technical solution, when the traction trolley moves to pull the pipeline, the main driving member and the auxiliary driving member respectively drive the support roller and the limit roller to rotate. On the one hand, it is beneficial to reduce the friction between the pipeline and the support roller and the limit roller. On the other hand, the support roller and the limit roller cooperate with the traction trolley to pull and transmit the pipeline, so that the pipeline can enter the bridge more smoothly.

[0018] Preferably, the support frame is further provided with a lifting drive member, which is drivingly connected to the auxiliary support and is used to drive the auxiliary support to lift and lower vertically; In step S1, before the pipeline is passed through the conveying gap between the support roller and the limiting roller, the auxiliary support is driven by the lifting drive member to drive the limiting roller to move upward to move away from the auxiliary limiting roller; After the pipeline is passed through the conveying gap between the support roller and the limiting roller, the auxiliary support is driven downward by the lifting drive member until the limiting roller on the auxiliary support abuts against the pipeline overlapped on the support roller.

[0019] By adopting the above technical solution, the conveying gap between the limiting roller and the support tube can be adjusted. On the one hand, it is convenient for the pipeline to pass through the conveying gap between the limiting roller and the support roller. On the other hand, the conveying gap can be adjusted to adapt to pipelines of different sizes and specifications, which is beneficial to improving the adaptability of the auxiliary support mechanism.

[0020] Preferably, fastening bolts are threadedly penetrated on opposite sides of the support frame; In step S1, after the support frame is inserted into the starting end of the bridge frame, the fastening bolts are screwed until the fastening bolts are tight against the bridge frame.

[0021] By adopting the above technical solution, the support frame is limited and fixed by tightening bolts to limit the support frame from separating from the bridge frame, so that the support frame can be more firmly installed at the starting end of the bridge frame.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. When laying the pipeline in the bridge, the end of the pipeline to be laid can be connected to the connecting part on the traction trolley, and then the traction trolley moves along the bridge to pull the pipeline into the bridge, so as to realize the laying of the pipeline in the bridge. The pipeline laying process does not require manual assistance to drag the pipeline into the bridge, which is beneficial to improve the laying efficiency of the pipeline in the bridge and reduce the safety hazards caused by high-altitude operations.

[0023] 2. By installing an auxiliary support mechanism at the starting end of the bridge, the pipeline entering the bridge will be inserted into the gap between the support roller and the limit roller. While the traction trolley moves along the bridge to pull the pipeline, the main drive and the auxiliary drive drive the support roller and the limit roller to rotate respectively to assist the trolley in pulling the pipeline together. On the one hand, the pipeline can enter the bridge more smoothly; on the other hand, the support roller and the limit roller are used to clamp and convey the pipeline to achieve the correction and limit of the pipeline, reduce the entanglement of the pipeline during the transmission process, and facilitate the overall layout of the pipeline. At the same time, it is beneficial to limit the contact and friction between the pipeline and the end of the bridge when entering the bridge, and reduce the damage to the outer skin of the pipeline.

[0024] 3. The lifting drive component drives the auxiliary support to drive the limit roller to rise and fall vertically, so that the conveying gap between the support roller and the limit roller can be adjusted. Before the pipeline is inserted into the conveying gap, the lifting drive component can be used to drive the auxiliary support to drive the limit roller to move upward to increase the conveying gap between the support roller and the limit roller, making it easier for the pipeline to penetrate into the conveying gap. After the pipeline penetrates the conveying gap, the lifting drive component is used to drive the auxiliary support to move downward until the limit roller on the auxiliary support abuts against the pipeline overlapped on the support roller, so as to cooperate with the support roller to clamp and limit the pipeline.

[0031] The following is combined with Figure 2-5 This application is described in further detail.

[0032] The present application embodiment discloses a method for installing and constructing an electrical bridge pipeline. Figure 2 and Figure 3 , including the following steps: S1: Preparation for threading: Install an auxiliary support structure at the end of the bridge 1; and move the traction trolley 3 to the starting end of the bridge 1.

[0033] The auxiliary support mechanism includes a support frame 2. In this embodiment, the support frame 2 is specifically an aluminum alloy square tube. The support frame 2 can be sleeved on the bridge frame 1. A plurality of fastening bolts 20 are threadedly penetrated on both opposite sides of the support frame 2. The end of the support frame 2 away from the bridge frame 1 is connected to a main support 21. A support roller 22 is rotatably mounted on the main support 21. The support roller 22 is used for overlapping the pipeline. The main support 21 is also provided with a main driving member 23 for driving the support roller 22 to rotate around its own axis. Specifically, the main driving member 23 is a reduction motor.

[0034] The support frame 2 is further connected to a secondary support 24 away from the bridge frame 1. The secondary support 24 is located above the main support 21. The secondary support 24 is rotatably connected to a limit roller 25. The limit roller 25 and the support roller 22 are arranged opposite to each other, and a conveying gap for the pipeline to pass through is formed between the limit roller 25 and the support roller 22. The secondary support 24 is also provided with a secondary driving member 26 for driving the limit roller 25 to rotate. Specifically, the secondary driving member 26 is a reduction motor.

[0035] A lifting drive component is supported on the top of the support frame 2, and the lifting drive component includes an electric cylinder 27 fixed on the top of the support frame 2, and the electric cylinder 27 is vertically arranged upward; an extension rod 241 is vertically connected to the top of the auxiliary support 24, and the top of the piston rod of the electric cylinder 27 is connected to the top of the extension rod 241, so that the lifting drive component is driven and connected to the auxiliary support 24. Subsequently, the electric cylinder 27 drives its own piston rod to extend and retract, so as to drive the auxiliary support 24 to rise and fall vertically, so that the conveying gap between the limiting roller 25 and the support roller 22 can be adjusted.

[0036] Reference Figure 4 and Figure 5 The traction trolley 3 is an existing electric trolley. A connecting portion 31 for connecting a pipe 312 is provided on the traction trolley 3, and the connecting portion 31 includes a connecting plate 311 vertically connected to the traction trolley 3. The connecting plate 311 is located at the rear end of the traction trolley 3. A plurality of connecting pipes 312 are fixedly passed through the connecting plate 311 in a horizontal direction, and the connecting pipes 312 are used for passing the pipelines. The outer circumference of the connecting pipes 312 is also threaded with locking bolts, and one end of the locking bolts extends into the inner cavity of the connecting pipes 312. Subsequently, the end of the pipeline to be laid is passed into the connecting pipe 312, and the locking bolts are screwed until they are tightly pressed against the pipeline in the connecting pipe 312, so that the pipeline can be firmly connected to the traction trolley 3.

[0037] A connecting rod 32 is also horizontally arranged at the front end of the traction trolley 3, and one end of the connecting rod 32 is fixed to the traction trolley 3 through a plurality of nuts. A scraper plate 33 is vertically connected to one end of the connecting rod 32 away from the traction trolley 3, and both ends of the scraper plate 33 extend to opposite sides of the traction trolley 3 respectively; when the traction trolley 3 is located inside the bridge frame 1, the scraper plate 33 is arranged in contact with the inner wall of the bottom of the bridge frame 1.

[0038] Reference Figure 2 and Figure 5 , the specific steps of step S1 are as follows: S1.1: Installation of auxiliary support structure: After the end of the support frame 2 away from the main support 21 is sleeved on the starting end of the bridge frame 1, tighten the fastening bolts 20 on both sides of the support frame 2 until the fastening bolts 20 abut against the outer side of the bridge frame 1; S1.2: The traction trolley 3 is positioned: the traction trolley 3 is moved to the starting end of the bridge frame 1; S2: Pipeline connection: Connect the pipeline to be installed to the connecting portion 31 on the traction trolley 3; the specific steps are as follows: S2.1: The electric cylinder 27 drives the auxiliary support 24 to drive the limiting roller 25 to move upward; S2.2: insert the pipeline into the conveying gap between the support roller 22 and the limiting roller 25; S2.3: Insert the pipeline into the corresponding connecting pipe 312 on the connecting plate 311 on the traction trolley 3, and tighten the locking bolt on the connecting pipe 312 until the locking bolt and the pipeline in the connecting pipe 312 are tightly pressed, so as to realize the connection between the pipeline and the traction trolley 3; S2.4: The auxiliary support 24 is driven by the electric cylinder 27 to drive the limiting roller 25 to move downward until the limiting roller 25 abuts against the pipeline overlapped on the supporting roller 22.

[0039] S3: Pipeline traction: The pipeline is driven to move along the extension direction of the bridge 1 by the traction trolley 3; at the same time, the support roller 22 and the limit roller 25 are driven to rotate by the main driving member 23 and the auxiliary driving member 26 respectively; until the pipeline is pulled into the bridge 1.

[0040] S4: Disconnection: Disconnect the connection between the connecting portion 31 of the traction trolley 3 and the pipeline. The specific steps are as follows: S4.1: Pipeline separation: Tighten the locking bolt 313 of the connecting pipe 312 to keep the locking bolt 313 away from the pipeline; S4.2: Removal of the traction trolley 3: Pull out the pipeline from the connecting pipe 312, and remove the traction trolley 3 from the bridge 1; S4.3: Removal of the auxiliary support mechanism: loosen the locking bolts on both sides of the support frame 2 and pull the support frame 2 out from the starting end of the bridge frame 1.

[0041] After the pipeline is connected to the connecting part 31 on the traction trolley 3, the traction trolley 3 is used to move along the bridge frame 1 to the end of the bridge frame 1 to pull the pipeline into the inside of the bridge frame 1, thereby realizing the laying of the pipeline inside the bridge frame 1. There is no need to manually drag the pipeline into the bridge frame 1, which is beneficial to improving the laying efficiency of the pipeline of the bridge frame 1 and reducing a series of safety hazards caused by high-altitude operations.

[0042] By setting the scraper plate 33 at the front end of the traction trolley 3, when the traction trolley 3 moves along the bridge frame 1, the scraper plate 33 can push the parts and debris such as crushed sand and stones remaining in the bridge frame 1 when the bridge frame 1 is installed to the end of the bridge frame 1, thereby realizing automatic cleaning of the debris inside the bridge frame 1 and reducing the situation in which the subsequent pipelines are rubbed against the residual debris inside the bridge frame 1 during the process of being towed into the bridge frame 1, resulting in surface damage.

[0043] By supporting an auxiliary installation mechanism at the starting end of the bridge frame 1, after the pipeline is passed through the conveying gap between the limiting roller 25 and the supporting roller 22, the supporting roller 22 on the auxiliary supporting mechanism can be used to support the pipeline entering the bridge frame 1 away from the edge of the starting end of the bridge frame 1, thereby limiting the situation in which the pipeline surface is damaged due to friction with the edge of the end of the bridge frame 1 during the process of entering the interior of the bridge frame 1.

[0044] While the traction trolley 3 moves along the bridge 1 to pull the pipeline, the main driving member 23 and the auxiliary driving member 26 respectively drive the support roller 22 and the limit roller 25 to rotate; the support roller 22 and the limit roller 25 are used to clamp and convey the pipeline. On the one hand, the pipeline section entering the bridge 1 is corrected and limited so that several pipelines can remain in a relatively horizontal state; the bending of the pipeline and other reasons can reduce the entanglement of adjacent pipelines in the subsequent traction process, resulting in difficulties in cable management; on the other hand, the rotation of the support roller 22 and the limit roller 25 can cooperate with the traction trolley 3 to assist in traction of the pipeline, so that the pipeline can enter the bridge 1 more smoothly.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
