Abstract
Description
Technical Field
[0001] This utility model relates to the field of subway track construction technology, specifically to a device for a subway tunnel transition section pouring and transporting pump truck. Background Technology
[0002] During subway track construction, due to unstable settlement at the side passage location, a 50-meter section of track bed is usually used as a temporary transition. This section of track bed is typically poured after the entire line is completed and the civil engineering settlement test results are available.
[0003] The conventional pouring method involves using a rail-mounted flatbed cart to carry a fixed mixing tank, which pulls the concrete to the pouring location. A small hopper is mounted on a hand-pushed flatbed cart, and the concrete is poured manually by pushing the hopper. To prevent changes in the alignment after fine-tuning, the hopper capacity should not exceed 1 cubic meter. 3 Pouring 50 cubic meters of track bed requires 150 cubic meters of concrete. This means that it would take 36 hours to complete the pouring by manually pushing the concrete 150 times. This pouring method results in a large number of concrete transportation turnovers and a long construction period, which seriously affects the overall project progress. Furthermore, the multiple transportation processes can easily affect the already finely adjusted track line, increase the risk of track deviation, and easily affect the construction accuracy and quality of the subway track.
[0004] To solve the above technical problems, we designed a device for a concrete pump truck used for pouring and transporting concrete in the transition section of a subway tunnel. Utility Model Content

This device has the advantages of improving construction efficiency, reducing labor intensity, reducing track disturbance and concrete waste, and shortening the construction cycle. It solves the problem that traditional pouring methods result in multiple concrete transport turnovers and long construction cycles, which seriously affect the overall project progress.

A second crossbar is welded to the bottom of the first crossbar, and a first longitudinal bar is welded to the opposite side of the first crossbar. Connecting frames are welded to the right side of the first longitudinal bar and both sides of the traction plate. A ground pump is placed on the top of the second crossbar. A limiting mechanism, including a limiting frame, is bolted to the left side of the top of the second crossbar. A bracket is bolted to the left side of the top of the traction plate, and a mixing tank is movably connected to the top of the bracket. An engine is bolted to the right side of the top of the traction plate. A first traveling wheel is bolted to the bottom of the first crossbar, and an oil tank is bolted to the right side of the top of the traction plate.
[0007] Preferably, a lead screw is movably connected to the rear side of the inner cavity of the limiting frame via a bearing. The threads on the front and rear sides of the lead screw have opposite directions. Adjusting plates are threaded onto both the front and rear sides of the lead screw. An adjusting rod is riveted to the left side of the adjusting plate. A limiting plate is riveted to the left end of the adjusting rod. The front end of the lead screw extends through to the front side of the limiting frame and is connected to a handwheel via bolts.
[0008] Preferably, a guide hole is provided on the left side of the limiting frame, and the left end of the adjusting rod passes through the guide hole.
[0009] Preferably, a refueling pipe is connected to the right side of the top of the fuel tank, and a pipe cap is threaded onto the surface of the refueling pipe.
[0010] Preferably, a second longitudinal bar is welded to the bottom of the second crossbar, and the number of the second longitudinal bars is three.
[0011] Preferably, a guide plate is bolted to the left side of the bracket, and second traveling wheels are bolted to the four corners of the bottom of the traction plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1.

The first vertical bar is connected to the traction plate through the connecting frame and a pin. The traction plate drives the first vertical bar to move. When the ground pump and the mixing tank reach the pouring location, the concrete inside the mixing tank is poured into the ground pump. Then, the user pushes the ground pump to move on the track surface through the first traveling wheel, and the ground pump pours the concrete.
[0014] 2. This utility model has the advantage of limiting function through the cooperation of limiting mechanism and limiting frame. When it is necessary to limit and fix the ground pump, rotate the handwheel. The handwheel drives the lead screw to rotate. The lead screw causes the two adjusting plates to move relative to each other. The adjusting plates drive the adjusting rod and the limiting plate to move relative to each other. The limiting plate clamps on the surface of the ground pump's support leg, thereby limiting and fixing the ground pump and preventing the ground pump from shifting when moving.

[0020] Please see Figures 1-4A device for a concrete pump truck used for pouring concrete in a transition section of a subway tunnel includes a first crossbar 1 and a traction plate 2. A second crossbar 3 is welded to the bottom of the first crossbar 1. By setting the second crossbar 3 and welding it to the bottom of the first crossbar 1, it forms a more stable lateral support frame together with the first crossbar 1, providing a placement platform for equipment such as a ground pump 22, ensuring the stability of the ground pump 22 during placement and use, and enhancing the lateral load-bearing capacity of the entire device. A first longitudinal bar 4 is welded to the opposite side of the first crossbar 1. Connecting frames 5 are welded to the right side of the first longitudinal bar 4 and both sides of the traction plate 2. By setting the connecting frames 5 and welding them to the right side of the first longitudinal bar 4 and both sides of the traction plate 2, respectively, it is used to achieve the first The detachable connection between the longitudinal bar 4 and the traction plate 2, via connectors such as pins, facilitates assembly and disassembly of the device during transportation and use, improving the flexibility of its use. A ground pump 22 is placed on the top of the second crossbar 3. By installing the ground pump 22, concrete from the mixing tank 9 can be transported to a designated location for pouring, achieving mechanized concrete pouring. Compared to traditional manual pouring, this significantly improves pouring efficiency and reduces labor intensity. A limit mechanism 6, including a limit frame 7, is bolted to the left side of the top of the second crossbar 3. A bracket 8 is bolted to the left side of the top of the traction plate 2. The bracket 8, installed on the left side of the top of the traction plate 2, supports the concrete... The mixing tank 9 is stably placed on the traction plate 2, ensuring it maintains a certain height and position during operation, facilitating concrete mixing and transportation. The mixing tank 9 is movably connected to the top of the support frame 8. By setting up the mixing tank 9, it is used to store and mix concrete, ensuring the concrete remains uniform during transportation and pouring, preventing segregation, and improving the quality of concrete pouring. Its capacity also allows for the storage of a certain amount of concrete, reducing the number of times concrete needs to be transported and handled. An engine 10 is bolted to the right side of the top of the traction plate 2, providing power to components requiring power, such as the mixing tank 9. The mixing tank 9 is driven to perform mixing operations, ensuring the normal operation of the concrete mixing process. The bottom of the first crossbar 1 is bolted to the first traveling wheel 11. By setting the first traveling wheel 11, the structure where the ground pump 22 is located can move on the track surface, which facilitates the position adjustment and movement of the ground pump 22 at the pouring site, realizes uniform concrete pouring, and improves the flexibility and convenience of pouring. The right side of the top of the traction plate 2 is bolted to the oil tank 12. By setting the oil tank 12, the oil required by the engine 10 is stored, providing fuel guarantee for the continuous operation of the engine 10, ensuring that the device will not be interrupted due to insufficient fuel during operation, and ensuring the continuity of construction.
[0021] Please see Figure 1 and Figure 3A lead screw 13 is movably connected to the rear side of the inner cavity of the limiting frame 7 via a bearing. The threads on the front and rear sides of the lead screw 13 have opposite directions. Adjusting plates 14 are threaded on both the front and rear sides of the lead screw 13. An adjusting rod 15 is riveted to the left side of the adjusting plate 14. A limiting plate 16 is riveted to the left end of the adjusting rod 15. By setting the limiting plate 16, it can be clamped on the surface of the support leg of the ground pump 22 to achieve limiting and fixing of the ground pump 22. It directly contacts the ground pump 22 to play a limiting role and ensure the stability of the ground pump 22. The front end of the lead screw 13 extends through to the front side of the limiting frame 7 and is connected to a handwheel 17 by bolts.
[0022] Please see Figure 3 The left side of the limiting frame 7 is provided with a guide hole 18. By setting the guide hole 18, the movement of the adjusting rod 15 can be guided, ensuring that the adjusting rod 15 and the limiting plate 16 move in the correct direction during the movement, avoiding deviation, and making the limiting operation more accurate and reliable. The left end of the adjusting rod 15 passes through the guide hole 18.
[0023] Please see Figure 1 A refueling pipe is connected to the right side of the top of the fuel tank 12. By setting the refueling pipe, it is convenient for users to add fuel to the fuel tank 12. The surface of the refueling pipe is fitted with a pipe cap.
[0024] Please see Figure 1 and Figure 2 The bottom of the second horizontal bar 3 is welded with a second vertical bar 19. By setting the second vertical bar 19, the overall stability and load-bearing capacity of the device can be enhanced, so that the device can more stably support the weight of equipment such as the ground pump 22 and the load generated during operation. There are three second vertical bars 19.
[0025] Please see Figure 1 A guide plate 20 is bolted to the left side of the support 8. When concrete in the mixing tank 9 needs to be poured into the ground pump 22, the guide plate 20 guides the flow direction of the concrete, so that the concrete can flow smoothly and accurately into the ground pump 22, avoiding concrete spillage and reducing concrete waste, while ensuring the smooth concrete delivery process. The four corners of the bottom of the traction plate 2 are bolted to the second traveling wheels 21. By setting the second traveling wheels 21, the traction plate 2 can be moved. Together with the first traveling wheels 11, the entire device is more stable and flexible when moving, which facilitates the transportation and movement of the device in the subway tunnel.
[0026] In use, the mixing tank 9 is mounted on the surface of the towing plate 2 via the bracket 8. The towing plate 2 is then connected to the towing vehicle via the connecting frame 5 on the right side. The ground pump 22 is then mounted on the surface of the second crossbar 3. The handwheel 17 is rotated, causing the lead screw 13 to rotate. The lead screw 13 causes the two adjusting plates 14 to move relative to each other. The adjusting plates 14 cause the adjusting rod 15 and the limiting plate 16 to move relative to each other. The limiting plate 16 clamps onto the support leg surface of the ground pump 22, thus limiting and fixing the ground pump 22 to prevent displacement during movement. The first longitudinal bar 4 on the right side is connected to the towing plate 2 via the connecting frame 5 and a pin. The towing plate 2 drives the first longitudinal bar... 4. The first traveling wheel 11 moves on the surface of the track. When the ground pump 22 and the mixing tank 9 reach the pouring location, the engine 10 draws oil from the oil tank 12. The output shaft of the engine 10 drives the drive shaft on the right side of the mixing tank 9, thereby mixing the concrete inside the mixing tank 9. Then, the concrete inside the mixing tank 9 is poured into the ground pump 22 through the guide plate 20. When the position of the ground pump 22 needs to be moved, the connecting frame 5 pin between the traction plate 2 and the first longitudinal rod 4 is removed. Then, the user pushes the ground pump 22 to move on the track surface through the first traveling wheel 11. The ground pump 22 pours the concrete evenly.
[0027] In summary, the concrete pump truck device for the transition section of the subway tunnel, through the cooperation of the first horizontal bar 1, the traction plate 2, the second horizontal bar 3, the first vertical bar 4, the connecting frame 5, the limiting mechanism 6, the limiting frame 7, the bracket 8, the mixing tank 9, and the limiting mechanism 6 and the limiting frame 7, solves the problem that traditional pouring methods involve multiple concrete transport turnovers and long construction cycles, which seriously affect the overall project progress.
