Description

Technical Field

[0001] This application relates to the technical field of concrete pump trucks, and in particular to a frost-resistant concrete pump truck for concrete pouring. Background Technology

[0002] In the field of modern construction, concrete pump trucks, as efficient concrete conveying equipment, are widely used in high-rise buildings, bridge projects, tunnel construction, and other scenarios. However, traditional concrete pump trucks have many technical bottlenecks in terms of pouring flexibility, adaptability to complex environments, and construction efficiency, making it difficult to meet diverse construction needs.

[0003] The rigid structure of traditional concrete pump truck pouring pipes makes them unsuitable for complex construction environments. In space-constrained scenarios such as tunnel construction and indoor renovations, rigid pipes, unable to bend, often create pouring blind spots, preventing concrete from reaching designated locations. Some projects use manual dragging of flexible hoses to assist pouring, but this method is not only labor-intensive but also prone to hose wear, concrete leakage, and even safety accidents. Furthermore, rigid pipes lack buffering capacity when encountering obstacles, making them susceptible to deformation and breakage upon impact, affecting the normal operation of the pump truck. Utility Model Content

[0004] In order to achieve automatic adjustment of the position and angle of the pouring pipe, this application provides a concrete pump truck for frost-resistant concrete pouring.

[0005] This application provides a concrete pump truck for frost-resistant concrete pouring, which adopts the following technical solution:

[0006] A frost-resistant concrete pump truck includes a pump truck body. A folding boom assembly is fixedly installed on the top of the pump truck body. A pouring pipe is installed at the head of the folding boom assembly. The pouring pipe is fixedly connected to the folding boom assembly, and an equipment base is sleeved and fixed on the pouring pipe. An adjustable frame is sleeved and installed on the equipment base. The adjustable frame is rotatably connected to the equipment base, and a drive mechanism for driving the adjustable frame to rotate is also fixedly installed on the equipment base. A vertical plate base is fixedly installed at the lower end of the adjustable frame. A movable plate is installed on the side of the vertical plate base. The head of the movable plate is rotatably connected to the vertical plate base, and an electric cylinder for driving the movable plate to flip is also provided on the vertical plate base.

[0007] By adopting the above technical solution, the pump truck body is designed for convenient and flexible movement in different locations. The boom's folding mechanism allows for a multi-section folding design, reducing its size during transport and allowing it to be extended to a suitable length and height during operation to deliver the pouring pipe to the designated location. The pouring pipe connects to the pouring pump for pouring operations. The equipment base, drive mechanism, upright base, and movable plate design facilitate better control of the pouring pipe's position during pouring. The movable plate can be easily rotated via an electric cylinder to change the pouring pipe's position. Compared to the traditional method of manual control of the pouring pipe, this approach is not only more flexible but also effectively improves construction safety.

[0008] Optionally, the casting pipe includes a connecting disc, a rigid pipe section, and a flexible pipe section. The connecting disc is fixedly installed at the head of the rigid pipe section, and the flexible pipe section is sealed and connected to the lower end face of the rigid pipe section.

[0009] By adopting the above technical solution, the pouring pipe uses a combination design of a connecting plate, a rigid pipe section, and a flexible pipe section. The connecting plate facilitates a stable connection with the folding boom assembly, ensuring the stability of the pouring pipe during operation. The rigid pipe section ensures the basic path for concrete delivery, possessing good strength and rigidity to prevent leakage during concrete transport. The flexible pipe section increases the flexibility of pouring; construction personnel can appropriately bend and adjust the flexible pipe section according to the actual pouring location requirements, allowing concrete to be accurately poured to the target location, adapting to the pouring needs of different shapes and positions.

[0010] Optionally, the equipment base includes a seat ring and a bracket for rotatable mounting of an adjustable frame. The bracket is symmetrically mounted on the upper end face of the seat ring and is fixedly connected to the seat ring.

[0011] By adopting the above technical solution, the seat ring of the equipment base is sleeved on the casting pipe, providing an installation foundation for the entire adjustable frame and drive mechanism. The brackets are symmetrically installed on the upper end face of the seat ring, and their function is to provide rotational support for the ring sleeve of the adjustable frame, so that the adjustable frame can rotate smoothly on the equipment base, ensuring the stability and reliability of the rotation process, and providing a good foundation for subsequent angle adjustment.

[0012] Optionally, the adjustable frame includes a vertical plate, side frames, and a ring frame. There are two sets of side frames, and the two sets of side frames are symmetrically installed on both sides of the vertical plate. The ring frame is rotatably installed on the bracket and fixedly installed between the two sets of side frames.

[0013] By adopting the above technical solution, the adjustable frame consists of a vertical plate section, side frames, and a ring-shaped sleeve frame. The vertical plate section provides connection points for the installation of the upright plate base, ensuring a stable connection between the upright plate base and the adjustable frame. The side frames are symmetrically installed on both sides of the vertical plate section, enhancing the overall structural strength of the adjustable frame and preventing deformation during rotation. The ring-shaped sleeve frame is rotatably mounted on the bracket, and through cooperation with the drive mechanism, it enables the adjustable frame to rotate, thereby driving the upright plate base and the movable plate to perform circumferential position adjustment, expanding the coverage area of ​​the pouring.

[0014] Optionally, the drive mechanism includes a motor and a drive gear, with the motor fixedly mounted on the upper end face of the seat ring and the drive gear fixedly mounted on the output end of the motor.

[0015] By adopting the above technical solution, the motor of the drive mechanism is fixedly installed on the upper end face of the seat ring, and the drive gear at the output end of the motor meshes with the large gear ring on the lower end face of the ring sleeve frame. The motor, as the power source, drives the large gear ring to rotate through the drive gear, thereby driving the adjustable frame to rotate. This gear transmission method features high transmission efficiency and high transmission precision, enabling accurate control of the rotation angle of the adjustable frame and meeting the precise adjustment requirements for the pouring position under different construction scenarios.

[0016] Optionally, a large toothed ring that meshes with the drive gear is installed on the lower end face of the ring sleeve frame, and the large toothed ring is fixedly connected to the ring sleeve frame.

[0017] By adopting the above technical solution, transmission is achieved through the meshing of the drive gear and the large gear ring.

[0018] Optionally, the upright plate base includes a base box and a connecting vertical rod, the connecting vertical rod being fixedly installed on the upper end face of the base box and inserted and fixed in the vertical plate portion.

[0019] By adopting the above technical solution, the base of the upright plate provides space and support for the installation of the movable plate and the electric cylinder. The connecting vertical rod is fixedly installed on the upper end face of the base and inserted into the vertical plate, so that the upright plate is firmly connected to the adjustable frame, ensuring that the upright plate can stably transmit force during the rotation of the movable plate and ensuring the stability of the entire structure.

[0020] Optionally, the movable plate includes a main plate and a collar sleeved on the flexible tube. The collar is installed on one side of the main plate and is fixedly connected to the main plate.

[0021] By adopting the above technical solution, the main body of the movable plate provides an installation base for the collar, which is fitted onto the flexible hose. When the electric cylinder drives the movable plate to rotate, the collar can adjust the angle of the flexible hose, further increasing the pouring angle range of the pouring pipe, allowing concrete to be poured at different angles to adapt to complex construction environments.

[0022] In summary, this application includes at least one of the following beneficial technical effects: By driving the adjustable frame to rotate via a drive mechanism, the position of the pouring pipe in the circumferential direction can be adjusted. Simultaneously, the electric cylinder drives the movable plate to rotate, allowing for adjustment of the pouring pipe's angle. This flexible adjustment function enables the concrete pump truck to adapt to pouring needs of different shapes and locations, improving construction flexibility and efficiency. The flexible hose design of the pouring pipe and the angle adjustment function of the movable plate allow the pump truck to accurately pour concrete to the target location even in complex construction site environments, enabling normal operation even in narrow or irregular spaces.
