Description

Technical Field

[0001] The utility model relates to the technical field of concrete pump trucks, and more specifically, to a towable concrete pump truck. Background Art

[0002] A trailer concrete pump truck is a portable concrete pump, which is usually composed of concrete delivery pipelines, diesel engines, hydraulic pumps, control systems and other parts. It is easy to operate, has the advantages of strong flexibility and easy mobility, and is often used in small construction sites. It is usually called a "concrete pump" or "diesel trailer pump" on the construction site. The pump truck needs to be adjusted to a horizontal state before operation, which is crucial for the normal operation of the pump truck and the delivery of concrete. However, since the ground on the construction site is often uneven, the existing pump truck is prone to tilt during operation. This tilted state will cause uneven concrete delivery and concrete accumulation problems, increase the failure rate of the pump truck, and shorten its service life. At the same time, the pump truck working in a tilted state may also cause the stability of the equipment to decrease, and it is easy to overturn and other accidents, which poses a potential danger to construction personnel and equipment. Therefore, a trailer concrete pump truck is proposed to solve the above problems. Utility Model Content

[0033] The staff drives the towed concrete pump truck to the construction site, and then needs to support the towed concrete pump truck. Now, by controlling the hydraulic cylinder 8, the support plate 1 and the fixed plate 7 are lifted upward. When they are supported to a suitable height, the staff finds that the towed concrete pump truck is tilted. Now, the staff holds the rocker 14 to rotate it, and drives the rotating shaft 2 16 to rotate inside the fixed column 23 through the manual rocker 14, and drives the tooth 2 27 to rotate through the rotating shaft 16. The tooth 2 27 is meshed with the tooth 1 26, and the threaded rod 2 24 is driven by the tooth 1 26 to rotate inside the threaded sleeve 9, so that the threaded sleeve 9 moves on the surface of the limit hole 25, and slowly adjusts the balance of the towed concrete pump truck.

[0034] The towed concrete pump truck needs to be supported at the construction site. Now, the support plate 1 and the fixed plate 7 are lifted upward by controlling the hydraulic cylinder 8. When the support plate 1 and the fixed plate 7 are supported to a suitable height, the staff finds that the towed concrete pump truck is tilted. Now, the rocker 14 is rotated by hand. The rotating shaft 16 and the tooth 27 are driven to rotate synchronously inside the fixed column 23 by the manual rocker 14. The tooth 27 is meshed with the tooth 1 26, and the threaded rod 24 is driven to rotate inside the threaded sleeve 9 by the tooth 1 26, so that the threaded sleeve 9 moves on the surface of the limit hole 25 and slowly moves. Adjust the balance of the trailer concrete pump truck. Compared with the traditional trailer concrete pump truck, the trailer concrete pump truck has four sets of adjustment balance mechanisms around the support plate 1. The trailer concrete pump truck can be adjusted to a balanced state by adjusting the balance mechanism, which can ensure the stability of concrete during transportation, reduce the possibility of blockage and leakage, and improve transportation efficiency. The horizontal balance position can reduce the wear and stress of the equipment, thereby extending the service life of the equipment, and finally improve the safety of construction, because the equipment working in a stable state can reduce the risk of accidents such as overturning, and protect the safety of construction personnel and equipment.

[0035] Among them, a box body 3 is fixedly installed on the top of the support plate 1, a motor 17 is fixedly installed inside the box body 3, a driving wheel 18 is fixedly installed on the outer surface of one end of the motor 17, a threaded rod 13 is movably installed inside the box body 3, a roller 20 is fixedly installed on the top of the threaded rod 13, and a transmission belt 10 is fixedly installed between the roller 20 and the driving wheel 18;

[0036] A movable plate 11 is movably mounted on the outer surface of the two threaded rods 13 , a vertical plate 21 is fixedly mounted on the bottom of the movable plate 11 , and a universal wheel 22 is fixedly mounted between the two vertical plates 21 .

[0037] The staff needs to move the towed concrete pump truck, and now turns on the motor 17 inside the box body 3. The motor 17 rotates clockwise, and the rotation of the motor 17 drives the drive wheel 18 to rotate, and then the drive wheel 18 drives the transmission belt 10 to rotate, and the rotation of the transmission belt 10 drives the roller 20 to rotate, and then the roller 20 drives the threaded rod 13 to rotate, and then the threaded rod 13 rotates inside the moving plate 11, so that the moving plate 11 slowly drives the vertical plate 21 and the universal wheel 22 to slowly descend, and then the support plate 1 is supported and moved, and the universal wheel 22 does not need to be moved. The universal wheel 22 is slowly raised by the counterclockwise motor 17 to collect the motor 17.

[0038] The towed concrete pump truck needs to be moved. Now, the motor 17 is turned on inside the box body 3. The motor 17 rotates clockwise, and the driving wheel 18, the transmission belt 10 and the roller 20 are driven to rotate synchronously through the rotation of the motor 17. The roller 20 drives the threaded rod 13 to rotate, and the threaded rod 13 rotates inside the moving plate 11, so that the moving plate 11 slowly drives the vertical plate 21 and the universal wheel 22 to slowly descend, and then the support plate 1 is supported and moved.

[0047] The working principle and use process of this utility model:

[0048] The staff drives the towed concrete pump truck to the construction site, and then needs to support the towed concrete pump truck. Now, by controlling the hydraulic cylinder 8, the support plate 1 and the fixed plate 7 are lifted upward. When they are supported to a suitable height, the staff finds that the towed concrete pump truck is tilted. Now, the staff holds the rocker 14 to rotate it, and drives the rotating shaft 2 16 to rotate inside the fixed column 23 through the manual rocker 14, and drives the tooth 2 27 to rotate through the rotating shaft 16. The tooth 2 27 is meshed with the tooth 1 26, and the threaded rod 2 24 is driven by the tooth 1 26 to rotate inside the threaded sleeve 9, so that the threaded sleeve 9 moves on the surface of the limit hole 25, and slowly adjusts the balance of the towed concrete pump truck.

[0049] The staff needs to move the towed concrete pump truck, and now turns on the motor 17 inside the box body 3. The motor 17 rotates clockwise, and the rotation of the motor 17 drives the drive wheel 18 to rotate, and then the drive wheel 18 drives the transmission belt 10 to rotate, and the rotation of the transmission belt 10 drives the roller 20 to rotate, and then the roller 20 drives the threaded rod 13 to rotate, and then the threaded rod 13 rotates inside the moving plate 11, so that the moving plate 11 slowly drives the vertical plate 21 and the universal wheel 22 to slowly descend, and then the support plate 1 is supported and moved, and the universal wheel 22 does not need to be moved. The universal wheel 22 is slowly raised by the counterclockwise motor 17 to collect the motor 17.
