Description

Technical Field

[0001] This utility model relates to the field of concrete mixer truck technology, and in particular to a tank structure for a tunnel-mounted concrete mixer truck. Background Technology

[0002] With the large-scale construction of tunnel infrastructure and the improvement of equipment technology in my country, shield tunneling is now developing towards large and extra-large cross-sections. As the tunnel cross-section expands, a series of tunnels with more complex functions are being put into construction. During tunnel construction, rail-mounted concrete mixer trucks are usually needed to transport concrete.

[0003] Utility model patent CN 215154217 U discloses a concrete transport tank for cement tank trucks, comprising a cement tank truck and a transport tank. The cement tank truck and the transport tank are compatible and electrically connected. A fixing column is fixedly connected to the inner wall of one side of the transport tank, and the fixing column is fixedly connected to an external fixing mechanism of the cement tank truck. A blocking strip and a telescopic strip are fixedly connected to both ends of the inner wall of the cement tank truck, respectively. A rotating ring is rotatably connected to the outside of the fixing column via a rotating shaft. An inclined rod is fixedly connected to one side of the rotating ring, and a counterweight is fixedly connected to one end of the inclined rod. A mixing plate is fixedly connected to one side of the inclined rod, and a material passage hole is opened at the bottom of the mixing plate. Several rectangular grooves are opened at the bottom of the counterweight. This utility model, by setting an inclined rod, causes the internal cement to rise during the rotation of the transport tank and allows the cement to fall freely, thereby enhancing the cement mixing effect and improving the protection of the cement during transport.

[0004] In practical applications, the concrete inside the transport tank requires continuous rotation and mixing. The transport vehicle is equipped with a separate power supply unit to power the tank. This not only increases the complexity and cost of the equipment, but also poses a challenge when operating in confined spaces such as tunnels, as the additional power supply unit may occupy valuable space and increase operational difficulty. Furthermore, the independent power supply unit requires regular maintenance and upkeep, further increasing overall operating costs.

[0005] Therefore, this utility model provides a tunnel-track-type concrete mixer truck tank structure to meet the requirements. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A tunnel-mounted concrete mixer truck tank structure includes a track body for transporting the tank, a transport frame at the top of the track body, two sets of track wheels at the bottom of the transport frame, the two sets of track wheels being connected by a linkage shaft, a first support plate and a second support plate fixedly connected to the top of the transport frame, and a mixing tank rotatably connected between the first support plate and the second support plate; and a drive assembly for rotating and mixing the mixing tank, the drive assembly being connected to the transport frame.

[0008] Optionally, the drive assembly includes a support block fixedly connected to the top of the transport frame, a support frame fixedly connected to the top of the support block, the support frame having a "C" shaped cross-section, and an internal cavity formed inside the support frame.

[0009] Optionally, a fixed plate is fixedly connected to the top of the transport frame, and a rotating shaft is rotatably connected inside the fixed plate. One end of the rotating shaft passes through and extends into the inner cavity. A transmission bevel gear is fixedly connected to the outside of the rotating shaft at one end of the inner cavity, and a transmission gear is fixedly connected to the outside of the mixing tank. The transmission gear meshes with the transmission bevel gear.

[0010] Optionally, a driven wheel is fixedly connected to the other end of the rotating shaft, and a driving wheel is fixedly connected to the outside of the linkage shaft. The driven wheel and the driving wheel are connected by a transmission belt.

[0011] Optionally, two auxiliary wheels are rotatably connected to both sides of the top of the support frame, and the surface of the auxiliary wheels is in contact with the outer surface of the mixing tank.

[0012] Optionally, the height of the first support plate is lower than that of the second support plate, a feeding hopper is fixedly connected to the top of the second support plate, one end of the feeding hopper is rotatably connected to the top of the mixing tank, and a valve is fixedly connected to the outside of the mixing tank located at one end of the first support plate.

[0013] Optionally, a traction block is fixedly connected to one end of the transport frame.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above scheme, by setting up a drive component, when the tanker car travels along the track, the track wheels drive the drive wheel to rotate via a linkage shaft. The drive wheel is connected to the driven wheel via a transmission belt, which in turn drives the rotating shaft to rotate. This linkage mechanism ensures that the mixing tank can continuously and stably mix the materials during the tanker car's movement. Since the mixing power of the mixing tank comes directly from the traction force of the track car, no additional power supply equipment is required, thereby reducing energy consumption and emissions. In construction scenarios with limited environments, such as tunnels, this design not only saves valuable space resources but also reduces pollution to the surrounding environment.

[0016] In the above solution, by setting up a support frame and auxiliary wheels, the support frame and auxiliary wheels provide additional support and guidance for the mixing tank, which greatly enhances the stability of the mixing tank during the mixing process. When the auxiliary wheels roll on the surface of the mixing tank, they cause slight vibration of the tank body, making it difficult for the concrete to adhere to the inner wall of the mixing tank, reducing concrete waste, and also reducing the difficulty and cost of cleaning the mixing tank. At the same time, since the concrete can come into more full contact with the inner wall of the mixing tank and be subjected to shear force during the mixing process, the mixing effect is further improved.

[0030] like Figures 1 to 4As shown, an embodiment of this utility model provides a tunnel-mounted concrete mixer truck tank structure, including a track body 1 for tank transport. A transport frame 2 is provided at the top of the track body 1, and two sets of track wheels 3 are provided at the bottom of the transport frame 2. The two sets of track wheels 3 are connected by a linkage shaft 15. A first support plate 5 and a second support plate 6 are fixedly connected to the top of the transport frame 2. A mixing tank 7 is rotatably connected between the first support plate 5 and the second support plate 6. The height of the first support plate 5 is lower than the height of the second support plate 6. A feed hopper 8 is fixedly connected to the top of the second support plate 6. One end of the feed hopper 8 is rotatably connected to the top of the mixing tank 7. A valve is fixedly connected to the outside of one end of the first support plate 5 of the mixing tank 7. One end of the transport frame 2 is fixedly connected to... The system includes a traction block 4 and a drive assembly. The drive assembly is used for rotating and stirring the mixing tank 7. The drive assembly is connected to the transport frame 2. The drive assembly includes a support block 9 fixedly connected to the top of the transport frame 2. A support frame 10 is fixedly connected to the top of the support block 9. The support frame 10 has a "C" shaped cross-section and an inner cavity 1001. A fixing plate 13 is fixedly connected to the top of the transport frame 2. A rotating shaft 12 is rotatably connected inside the fixing plate 13. One end of the rotating shaft 12 passes through and extends into the inner cavity 1001. A transmission bevel gear 11 is fixedly connected to the outside of the rotating shaft 12 at one end of the inner cavity 1001. A transmission gear 701 is fixedly connected to the outside of the mixing tank 7. The transmission gear 701 meshes with the transmission bevel gear 11. A driven wheel is fixedly connected to the other end of the rotating shaft 12, and a driving wheel is fixedly connected to the outside of the linkage shaft 15. The driven wheel and the driving wheel are connected by a transmission belt 14. During operation, the concrete to be transported is introduced into the mixing tank 7 through the feed hopper 8. Then, the railcar is connected to the traction block 4, so that the railcar can drive the transport frame 2 to move. During the movement of the transport frame 2, the rail wheel 3 drives the driving wheel to rotate through the linkage shaft 15. The driving wheel is connected to the driven wheel through the transmission belt 14, which in turn drives the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 drives the transmission bevel gear 11 to rotate in the inner cavity 1001. The transmission bevel gear 11 meshes with the transmission gear 701 on the outside of the mixing tank 7, thereby driving the mixing tank. 7. The mixing drum 7 begins rotating and mixing. As the concrete mixer truck travels along the track, the mixing drum 7 continuously rotates and mixes, ensuring uniform mixing of the concrete. The mixing intensity and frequency can be controlled by adjusting the speed of the track vehicle as needed. When the mixer truck arrives at the construction site, the truck's power system is stopped, and the valve at one end of the first support plate 5 of the mixing drum 7 is opened to unload the concrete to the designated location. After unloading, the valve is closed, and the mixing drum 7 and the feed hopper 8 are cleaned to prepare for the next use. Through the precise design of the drive components and the power transmission mechanism, the efficient rotational mixing of the mixing drum 7 is achieved, ensuring uniform mixing of the concrete. Utilizing the traction force of the track vehicle to drive the mixing drum 7 eliminates the need for additional power supply equipment, reducing energy consumption and emissions.In line with the trend of green and low-carbon development, the tanker truck has a compact structure and is easy to operate, reducing the labor intensity of operators and improving work efficiency.

[0031] In this embodiment, if Figures 1 to 3 As shown, two auxiliary wheels 1002 are rotatably connected to both sides of the top of the support frame 10. The surface of the auxiliary wheels 1002 is in close contact with the outer surface of the mixing tank 7. When the mixing tank 7 rotates and mixes under the action of the drive assembly, the auxiliary wheels 1002 roll on the outer surface of the mixing tank 7. This rolling contact not only provides additional support and ensures the stability of the mixing tank 7 during the mixing process, but also reduces vibration and noise during the mixing process through rolling friction. At the same time, due to the design of the auxiliary wheels 1002, vibration occurs when the auxiliary wheels 1002 move relative to the mixing tank 7. This effectively prevents concrete from sticking to the inner wall of the mixing tank 7. During the mixing process, the rolling action of the auxiliary wheels 1002 avoids the accumulation and adhesion of concrete. The auxiliary wheels 1002 provide additional support for the mixing tank 7 and enhance the stability of the mixing tank 7 during the mixing process. This helps reduce uneven mixing and concrete waste caused by shaking or shifting of the mixing tank 7. By replacing sliding friction with rolling friction, the auxiliary wheel 1002 significantly reduces vibration and noise during the mixing process. This not only improves the comfort of the construction environment but also helps protect the structure of the tank truck and mixing tank 7 from vibration damage. The rolling action of the auxiliary wheel 1002 effectively prevents concrete adhesion. This helps reduce concrete waste and the difficulty of cleaning the mixing tank 7, improving mixing efficiency and concrete quality. Due to the rolling action of the auxiliary wheel 1002, the concrete on the inner wall of the mixing tank 7 can be subjected to shear force more fully, thereby improving the mixing effect. This helps ensure the uniformity and consistency of the concrete, meeting the high requirements for concrete quality in fields such as tunnel construction.

[0032] The working principle provided by this utility model is as follows: During the working process, the concrete to be transported is introduced into the interior of the mixing tank 7 through the feed hopper 8. Then, the railcar is connected to the traction block 4, so that the railcar can drive the transport frame 2 to move. During the movement of the transport frame 2, the rail wheel 3 drives the drive wheel to rotate through the linkage shaft 15. The drive wheel is connected to the driven wheel through the transmission belt 14, which in turn drives the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 drives the transmission bevel gear 11 to rotate in the inner cavity 1001. The transmission bevel gear 11 meshes with the transmission gear 701 on the outside of the mixing tank 7, thereby driving the mixing tank 7 to start rotating and mixing. When the mixing tank 7 is rotating and mixing under the action of the drive component, the auxiliary wheel 1002 rolls on the outer surface of the mixing tank 7. This rolling contact not only provides additional support, ensuring the stability of the mixing tank 7 during the mixing process, but also reduces vibration and noise during the mixing process through rolling friction. At the same time, due to the design of the auxiliary wheel 1002, vibration occurs when the auxiliary wheel 1002 moves relative to the mixing tank 7, which can effectively prevent concrete from sticking to the inner wall of the mixing tank 7. During the mixing process, the rolling action of the auxiliary wheel 1002 avoids the accumulation and adhesion of concrete. As the tanker truck travels along the track, the mixing tank 7 continues to rotate and mix, ensuring that the concrete is mixed evenly. As needed, the intensity and frequency of mixing can be controlled by adjusting the travel speed of the track vehicle. When the tanker truck arrives at the construction site, the power system of the tanker truck is stopped, the valve at one end of the first support plate 5 of the mixing tank 7 is opened, and the concrete is unloaded to the designated location. After unloading, the valve is closed and the mixing tank 7 and the feed hopper 8 are cleaned to prepare for the next use.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
