A pipe installation auxiliary device in an underground passage

Abstract

This invention belongs to the field of pipeline installation technology and discloses an auxiliary device for pipeline installation in underground tunnels. The device includes a frame with two support plates on its top. A support plate slides vertically along one side of the support plate. Through the cooperation of interception and locking components, the locking plate, utilizing the resilience of a spring-loaded telescopic rod, ensures its inner wall continuously adheres to the outer surface of the roller, preventing the operator from pushing the pipeline. Even when the roller is movable, the raised interception plate further prevents pipeline movement. By adjusting the pipeline height to align it with the pipeline inside the tunnel, rotating the handle allows the roller to move. During the movement of the locking plate, the corrugated pipe is compressed, causing the air inside to push the pressure plate, thus fixing the position of the pipeline at the top of the device with the pipeline inside the tunnel, thereby improving the accuracy of the connection work.

Description

Technical Field

[0001] This invention belongs to the field of pipeline installation technology, specifically an auxiliary device for pipeline installation in underground passages. Background Technology

[0002] Underground passages refer to passageways located underground for passage, which can be pedestrian walkways, vehicular roads, or railway tunnels. These constructions typically require the pouring of concrete into the inner walls to secure the passageway and ensure safety during use. Underground passages also include pipelines used for cable laying and underground water circulation. Since these projects are rarely used for pedestrian traffic, concrete pipes are generally used in their construction. Before construction begins, the tunnel is pre-existing, and the pipes are then directly connected, with nuts used to secure the gaps between the pipes. Some pipes also have rubber gaskets installed at both ends for locking, thus sealing the interior of the pipe.

[0003] In existing technologies, pipes are typically placed on top of a dedicated support using a crane, and then moved and connected using rollers on the top of the support. However, this connection method usually relies on manual observation to determine whether the pipes inside the tunnel and the unfixed pipes are on the same horizontal line to ensure the accuracy of the connection. But during the tunnel construction process, the soil conditions inside the tunnel vary, and the soil may be submerged by the pipes inside the tunnel, causing the unfixed pipes to fail to connect successfully. This makes the connection of existing technologies very unstable. To address this, we provide an auxiliary device for pipe installation in underground passages. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides an auxiliary device for pipe installation in underground tunnels, which solves the problem that during the tunnel construction process, the soil inside the tunnel varies and the soil is very likely to be submerged by the pipes inside the tunnel, resulting in the failure of the unfixed pipes to be successfully connected, thus making the connection of the existing technology very unstable.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for pipe installation in underground passages, comprising a frame, wherein two bearing plates are provided on the top of the frame, and a support plate is vertically slidably mounted on one side of the bearing plates.

[0006] Adjustment component, the adjustment component being used to adjust the height of the support plate.

[0007] A locking component, used to change the operating state of the regulating component.

[0008] The locking attachments are two in number and located at the bottom of the support plate. These locking attachments are used to fix the position of the locking assembly.

[0009] A clamping assembly is provided to fix the position of the pipe inside the tunnel. Two locking, clamping, and adjusting assemblies are each provided and located on top of the support plate.

[0010] An interception component is used to restrict the pipe from moving to one side.

[0011] The locking assembly includes a locking plate that slides horizontally on the top of a support plate. A spring telescopic rod is fixedly installed on one side of the locking plate, and a connecting rod is movably installed on the bottom of the locking plate. Two locking blocks are fixedly installed on the circumference of the connecting rod, and a rotating handle is fixedly installed on the other side of the connecting rod.

[0012] Preferably, the other end of the spring telescopic rod is fixedly installed to the top of the support plate, and the connecting rod passes through the bottom of the support plate and the frame.

[0013] Preferably, the adjustment assembly includes an adjustment plate, an adjustment rod is provided on one side of the adjustment plate, the adjustment plate is movable on the inner wall of the support plate, a connecting rod is snapped onto one side of the adjustment plate, a nylon connecting cloth is fixedly installed on the top of the connecting rod, an adapter is fixedly installed on one side of the nylon connecting cloth, and a roller is rotatably installed on the bottom of the adapter.

[0014] Preferably, one side of the adjusting plate is provided with two racks for fixing the connecting rod. The connecting rod slides vertically inside the bearing plate. The bottom of the roller is rotatably installed with the top of the support plate. The outer surface of the roller is in contact with one side of the locking plate.

[0015] Preferably, the interception assembly includes an interception plate, which is vertically movable on the top of the support plate. A drive rod is hinged to the top of the interception plate, a commutator is movably installed in the middle of the drive rod, and a telescopic rod is hinged to the other side of the drive rod.

[0016] Preferably, the bottom of the telescopic rod is hinged to the locking plate, the commutator is fixed to the top of the support plate, and there are two telescopic rods, drive rods, and commutators respectively located on both sides of the intercepting plate.

[0017] Preferably, the clamping assembly includes a bellows, the bottom of which is fixedly connected to the top of the support plate. A pusher block is fixedly mounted on one side of the bellows, and an air tank is fixedly mounted on the other side of the bellows. An outer protective tube is fixedly mounted on one side of the air tank, and an extension rod is sleeved inside the outer protective tube. A clamping plate is hinged to one side of the extension rod.

[0018] Preferably, the corrugated pipe is connected to the outer protective pipe through the inner cavity of the gas tank, and the top of the gas tank is fixedly connected to one side of the adapter.

[0019] Preferably, the clamping plate is arc-shaped, and one side of the push block is fixed to the locking plate.

[0020] Two handles for adjusting the position of the connecting rod are provided on both sides of the connecting rod.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] This invention, through the coordinated use of interception and locking components, ensures that when the pipe is at the top of the roller, the locking plate, due to the resilience of the spring telescopic rod, will continuously adhere its inner wall to the outer surface of the roller, keeping the roller stationary and preventing the operator from pushing the pipe. Furthermore, when the locking plate is in the position of fixing the roller, it will also cause the interception component to enter the blocking state. Even if the roller is in a movable state, the raised interception plate will prevent the pipe from moving. At this time, by adjusting the height of the pipe to keep it at the same level as the pipe inside the tunnel, rotating the handle can make the roller movable. During the movement of the locking plate, it will squeeze the corrugated pipe, causing the air inside to push the pressure plate to move and fix the position between the top pipe of the device and the pipe inside the tunnel, thereby improving the accuracy of the docking operation.

[0023] This invention, through the cooperation of structures such as adjustment components and support plates, allows the adjustment plate to be pulled by an adjustment rod. At this time, the racks at both ends of the adjustment plate near the nylon connecting cloth will disengage from the outer surface of the connecting rod. Then, the support plate will descend due to its own weight. This allows the device to be used for pipes of different heights, thereby improving the applicability of the device.

[0024] This invention, through the cooperation of clamping components and locking plates, allows the locking plate to detach from the outer surface of the roller when the operator controls it. The locking plate then compresses the bellows, causing the internal air to push the extension rod. The extension rod is hinged to the pressure plate, and the air's compressibility allows the pressure plate to tilt to a certain extent, thus securing pipes of different sizes. Furthermore, the open top of the device allows the roller to also move and connect pipes of different sizes, simultaneously improving the device's working efficiency. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 8 As shown, the present invention provides an auxiliary device for pipe installation in underground passages, including a frame 100. Two bearing plates 700 are disposed on the top of the frame 100, and a support plate 200 is vertically slidably mounted on one side of the bearing plates 700 and the frame 100.

[0036] Adjustment component 300 is used to adjust the height of support plate 200.

[0037] Locking component 600 is used to change the operating state of regulating component 300.

[0038] There are two locking accessories 800, which are located at the bottom of the support plate 200. The locking accessories 800 are used to fix the position of the locking assembly 600.

[0039] The clamping assembly 400 is used to fix the position of the pipe inside the tunnel. Two locking assemblies 600, 400, and 300 are each provided and located on top of the support plate 200.

[0040] Interception component 500 is used to restrict the pipe from moving to one side.

[0041] The locking assembly 600 includes a locking plate 601, which slides horizontally on the top of the support plate 200. A spring telescopic rod 605 is fixedly installed on one side of the locking plate 601, and a connecting rod 602 is movably installed on the bottom of the locking plate 601. Two locking blocks 604 are fixedly installed on the circumference of the connecting rod 602. A rotating handle 603 is fixedly installed on the other side of the connecting rod 602. The other end of the spring telescopic rod 605 is fixedly installed on the top of the support plate 200, and the connecting rod 602 passes through the bottom of the support plate 200 and the frame 100.

[0042] The above solution, aided by the resilience of the spring telescopic rod 605, enables it to push the locking plate 601, resulting in better fixation of the locking plate 601 to the roller 3033. When the pipe is located at the top of the roller 3033, the possibility of pipe slippage is reduced, simultaneously improving the safety of the device. Once the pipe at the top of the device can be connected to the pipe inside the tunnel, the operator can simultaneously pull the connecting rod 602 and the locking plate 601 by rotating the handle 603. Furthermore, after the locking block 604 passes the locking accessory 800, the handle 603 can be rotated, at which point the locking block 604 changes from a vertical to a horizontal state. The resilience of the spring telescopic rod 605 forces the locking block 604 to adhere tightly to one side of the locking accessory 800, causing the locking plate 601 to no longer fix the roller 3033, thus simultaneously improving the safety performance of the device and the accuracy of the connection.

[0043] like Figure 2 Figure 3As shown, the adjustment assembly 300 includes an adjustment plate 301. An adjustment rod 302 is provided on one side of the adjustment plate 301. The adjustment plate 301 is movable on the inner wall of the support plate 700. A connecting rod 303 is snapped onto one side of the adjustment plate 301. A nylon connecting cloth 3031 is fixedly installed on the top of the connecting rod 303. An adapter 3032 is fixedly installed on one side of the nylon connecting cloth 3031. A roller 3033 is rotatably installed on the bottom of the adapter 3032. Two racks for fixing the connecting rod 303 are provided on one side of the adjustment plate 301. The connecting rod 303 slides vertically inside the support plate 700. The bottom of the roller 3033 is rotatably installed with the top of the support plate 200. The outer surface of the roller 3033 is in contact with one side of the locking plate 601. Two handles for adjusting the position of the connecting rod 303 are provided on both sides of the connecting rod 303.

[0044] The above solution is adopted as follows: When the device is ready to dock, but the pipe on the outer surface of the roller 3033 is not on the same horizontal line as the pipe inside the tunnel, the adjusting plate 301 is pulled by the adjusting rod 302, so that the rack on one side of the adjusting plate 301 is no longer fixed in the position of the connecting rod 303. At this time, the connecting rod 303, including its top structure, is in a vertically movable state and falls freely. The operator can adjust the position of the pipe and the support plate 200 by pulling down the handles on both sides of the connecting rod 303. Then, the adjusting plate 301 is pushed to fix the connecting rod 303 and the pipe. This structure helps the device to have a certain degree of applicability to tunnels of different heights.

[0045] like Figure 1 , Figure 2 , Figure 6 , Figure 8 As shown, the interception assembly 500 includes an interception plate 501, which is vertically movable on the top of the support plate 200. A drive rod 503 is hinged to the top of the interception plate 501. A commutator 504 is movably installed in the middle of the drive rod 503. A telescopic rod 502 is hinged to the other side of the drive rod 503. The bottom of the telescopic rod 502 is hinged to the locking plate 601. The commutator 504 is fixed to the top of the support plate 200. There are two telescopic rods 502, drive rods 503, and commutators 504, which are respectively arranged on both sides of the interception plate 501.

[0046] The above solution is adopted: such as Figure 5 The interceptor plate 501 shown in the diagram has most of its area located on top of the support plate 200. When the locking plate 601 fails to secure the roller 3033 properly, causing the pipe to slide on the outer surface of the roller 3033, the interceptor plate 501 will provide a certain degree of obstruction, thereby causing the pipe at the top of the device to collide with the pipe inside the tunnel, further improving the working performance of the device.

[0047] During the movement of the locking plate 601, the bottom of the telescopic rod 502 will move to one side. At this time, the telescopic rod 502 will gradually change from an inclined state to a vertical state. The top of the telescopic rod 502 will push one end of the bottom of the drive rod 503 upward, while the other side of the drive rod 503 will descend synchronously and press against the interceptor plate 501. At this time, the interceptor plate 501 will be located inside the support plate 200 and will no longer block the pipe, thus improving the ease of use of the device.

[0048] like Figure 2 , Figure 4 , Figure 5 As shown, the clamping assembly 400 includes a bellows 401, the bottom of which is fixedly connected to the top of the support plate 200. A pusher block 402 is fixedly mounted on one side of the bellows 401, and an air tank 403 is fixedly mounted on the other side of the bellows 401. An outer protective tube 4031 is fixedly mounted on one side of the air tank 403. An extension rod 4032 is sleeved inside the outer protective tube 4031. A pressure plate 4033 is hinged to one side of the extension rod 4032. The bellows 401 communicates with the outer protective tube 4031 through the inner cavity of the air tank 403. The top of the air tank 403 is fixedly connected to one side of the adapter 3032. The pressure plate 4033 is arc-shaped. One side of the pusher block 402 is fixedly mounted to the locking plate 601.

[0049] Using the above scheme: During the movement of the locking plate 601, the bellows 401 is also squeezed by the pusher block 402, allowing the air inside to enter the outer protective tube 4031. At this time, the air pushes the extension rod 4032 and gradually extends into the outer protective tube 4031. The extension rod 4032 is hinged to the pressing plate 4033. There are two outer protective tubes 4031 and two extension rods 4032. The air has a certain degree of compressibility and flowability, which allows the pressing plate 4033 to tilt to a certain extent after touching the pipe inside the tunnel, thereby fixing pipes of different sizes. Furthermore, the top of the device is open, which allows the roller 3033 to move and connect pipes of different sizes, thus improving the working efficiency of the device.

[0050] Working principle and usage process of this invention:

[0051] First, the pipe is placed inside the tunnel using a crane. Then, the second pipe to be connected is placed on the outer surface of roller 3033. Since roller 3033 is fixed by locking plate 601 and interceptor plate 501 is in an upward state, the pipe is fixed. Further, the pipe height needs to be adjusted to the appropriate position. First, the adjusting plate 301 is pulled by adjusting rod 302. At this time, the two racks on one side of adjusting plate 301 disengage from the outer surface of connecting rod 303, and connecting rod 303 is movably installed. Due to the weight of support plate 200 and the pipe itself, support plate 200 and its top structure fall downwards. When the pipe is level with the tunnel, adjusting plate 301 can be pushed back to its original position. At this point, the device... In a fixed state, by rotating the handle 603 and the connecting rod 602, the locking plate 601 can be pulled simultaneously and disengaged from the outer surface of the roller 3033. At this time, the roller 3033 is movably installed. Since one side of the roller 3033 is also connected to the top of the support plate 200 through the spring telescopic rod 605, this structure makes the fit between the locking plate 601 and the roller 3033 tighter and the fixing effect better. However, at the same time, after the locking plate 601 is disengaged from the roller 3033, the locking block 604 needs to be controlled to pass over the locking accessory 800. At this time, by rotating the handle 603 to rotate the connecting rod 602 and the locking block 604, the locking block 604 can be blocked by the locking accessory 800, and the locking plate 601 can no longer fit with the roller 3033.

[0052] During the operation of the locking assembly 600, the locking plate 601 will simultaneously drive the bottom of the telescopic rod 502 to move to one side. At this time, the telescopic rod 502 gradually changes from an inclined state to a vertical state. The top of the telescopic rod 502 simultaneously pushes one end of the bottom of the drive rod 503 upward, while the other side of the drive rod 503 descends synchronously and presses against the interceptor plate 501. At this time, the interceptor plate 501 no longer blocks the pipe and can be used for docking.

[0053] During the movement of the locking plate 601, the pushing block 402 will also squeeze the bellows 401. At this time, the bellows 401 is squeezed, and the air inside pushes the extension rod 4032, causing the extension rod 4032 to move outward from inside the outer protective tube 4031. At this time, the clamping plate 4033 will move to one side. There are two clamping components 400, which are respectively set on both sides of the support plate 200. At this time, the clamping plate 4033 will fix the pipe inside the tunnel to avoid docking errors. At this time, the external pipe can slide through the roller 3033. After docking is completed, the device can be returned to the initial position by rotating the handle 603. In this way, the docking work of the next pipe can be carried out.
