[0002] A concrete pump truck, also known as a concrete pump truck, is a heavy-duty engineering vehicle that integrates driving, pumping, and placing functions. Equipped with a specialized concrete pumping system and a retractable placing boom, it can efficiently deliver concrete to designated locations. The pump truck draws concrete from a batching plant or on-site mixer truck through its pumping system, then transports it via high-pressure pipelines to the end of the placing boom. The placing boom can be flexibly extended and its angle adjusted to ensure accurate and uniform pouring of concrete to the construction site. Pump trucks offer advantages such as high flexibility, high construction efficiency, and wide applicability, making them an indispensable piece of equipment in modern construction.

[0024] The following description is merely a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of the present invention should be considered within the protection scope of the present invention. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the protection scope of the present invention.

[0025] As shown in the figure, a tunnel arch pump truck with anti-tilting chassis includes a pump truck body 1, inside which is a truck bed. A water outlet trough is opened at the bottom of the truck bed, and a water pump 26 is fixedly connected inside the trough. One end of the water pump 26 is located inside the trough, and the other end is fixedly connected to the trough. A dilution pipe 27 is fixedly connected to the water pump 26, and the other end of the dilution pipe 27 is fixedly connected to an electric support 20 below a guide pipe 22. When the pump truck outputs cement and needs additional water, the water pump 26 draws water from the trough and sprays it through the dilution pipe 27 below the guide pipe 22 to dilute the sprayed cement.

[0026] The truck bed contains a transport structure, within which is a material conveying tank 2. An agitator is fixedly connected to the inner side of the material conveying tank 2. The material conveying tank 2 is tilted, and an electric cylinder 18 is fixedly connected to its bottom, driving the material conveying tank 2. The transport structure also includes a base 19, an electric support 20, a cement pump 21, and a guide pipe 22. The base 19 is fixedly connected to the truck bed, the electric support 20 is rotatably connected to the base 19, the cement pump 21 is fixedly connected to the bottom of the electric support 20, one end of the guide pipe 22 is connected to the cement pump 21, and the cement pump 21 is fixedly connected to the telescopic guide pipe 5. The electric cylinder 18 drives the transporting tank to rotate, agitating the cement inside during transport and discharge to prevent solidification.

[0027] The surface of the conveying tank 2 is equipped with a balancing structure, which includes a counterweight 3, a water storage tank 4, a telescopic guide pipe 5, a water delivery pipe 6, and a booster pump 7. The water delivery pipe 6 is connected to one side of the telescopic guide pipe 5, which is connected to the top of the conveying tank 2. The counterweight 3 is connected to one side of the top of the conveying tank 2. The booster pump 7 is connected to the surface of the counterweight 3, and one side of the booster pump 7 is connected to the outlet water tank. The water storage tank 4 is located inside the counterweight 3, and the other end of the water delivery pipe 6 is connected to the bottom of the counterweight 3 and extends into the water storage tank 4. During cement discharge, the cement inside the conveying tank 2 decreases from the top, causing the center of the conveying tank 2 to shift downward. The water pump 26 draws water from the water tank into the outlet water tank, increasing the weight on the top of the conveying tank 2 during cement discharge and balancing the conveying tank 2.

[0028] The water supply pipe 6 includes a pipe body 8, Velcro 9, a fixing groove 10, and a positioning sticker 11. The fixing groove 10 is located inside the pipe body 8. The Velcro 9 and the positioning sticker 11 are fixedly connected at both ends, and the Velcro 9 and the positioning sticker 11 are attached together. The positioning sticker 11 is fixedly connected to the inside of the fixing groove 10. A positioning plate 12 is fixedly connected to the outside of the water supply pipe 6. A rotating rod 15 is fixedly connected to one side of the positioning plate 12. A tray 16 is fixedly connected to the bottom of the rotating rod 15. A pressure plate 17 is rotatably connected to the top of the rotating rod 15. The upper surface of the tray 16 is attached to the water supply pipe 6. The pressure plate 17 is fixedly connected to the outside of the fixing groove 10 and the pipe body 8. The pressure plate 17 rotates around the rotating rod 15, pressing down on the positioning sticker 11 and the Velcro 9 inside the fixing groove 10 to close the water supply pipe 6, and vice versa. This controls whether water flows out of the water supply pipe 6 and adjusts the cement moisture content and the water volume in the outlet tank.

[0029] A horizontal telescopic bracket 23 is fixedly connected to the bottom side of the truck bed away from the bottom of the conveying tank 2. A vertical telescopic bracket 24 is fixedly connected to the bottom of the horizontal telescopic bracket 23. A suction cup 25 is fixedly connected to the bottom of the vertical telescopic bracket 24.

[0030] Working principle: When the pump truck needs to replenish water for cement output, the water pump 26 draws water from the water tank and sprays it from the dilution pipe 27 to the bottom of the guide pipe 22 to dilute the sprayed cement. The electric cylinder 18 drives the transport tank to rotate, stirring the cement in the tank during transportation and discharge to prevent solidification. The water pump 26 draws water from the water tank into the outlet tank, increasing the weight on top of the conveying tank 2 during cement discharge, thus balancing the conveying tank 2. The pressure plate 17 rotates around the rotating rod 15, pressing down on the positioning sticker 11 in the fixing groove 10 to adhere to the Velcro 9, thus closing the water supply pipe 6, and vice versa. This controls whether water flows out of the water supply pipe 6, adjusting the cement moisture content and the water volume in the storage tank 4.

[0031] In summary, by storing water in the water storage tank 4 during the cement discharge process of the pump truck, the weight of the top of the conveying tank 2 is increased; by controlling whether the water delivery pipe 6 replenishes water to the cement through the rotating rod 15, the water content of the cement and the water volume in the water storage tank 4 are controlled.
