The working principle of the concrete pump truck: the power of the automobile engine is transmitted to the hydraulic pump through the transfer box, and then the concrete pump is driven to work, and the transported concrete is sent to the pouring place of a certain height and distance through the distribution device on the boom system under the action of the concrete pump.
The limitations of the tow pump are:
① Pipelines must be laid on the building when used, and the preparation workload is large;
② With the change of watering position, the pipe outlet must be manually moved constantly, which is very inconvenient;
The movement of the drag pump itself is very inconvenient, so the drag pump always works in a fixed location until the project is completed, and the equipment utilization rate of this mode of work is very low.
In view of these shortcomings of the tow pump, in the 1970s, a concrete pump truck with driving, pumping and distributing functions was developed. Compared with the towed pump, the pump truck has the following advantages:
① With its own boom for fabric, open to the work site, can quickly open the boom for work, usually in half an hour can be ready;
② Equipped with hydraulic folding boom, flexible rotation in the working range, convenient and fast cloth, no dead Angle, and the pump pump speed is fast, generally in 90-150m3/h, high work efficiency.
③ High degree of automation, the whole car from the pump to the cloth can be operated by one person, and equipped with wireless remote control system, easy to operate;
Good mobile performance, after the completion of the operation in one place can be quickly transferred to another place to continue the operation, high equipment utilization rate, can be responsible for several places of concrete pumping at the same time. Recommended auxiliary equipment of concrete mixing station: JS double horizontal shaft forced concrete mixer, PLD concrete batching machine, cement silo, LSY screw conveyor, mixing station control system, concrete mixing transport tank, stable soil mixing station.
