Air cooler for pump truck and concrete pump truck

Abstract

The invention relates to an air cooler for a pump truck. The air cooler for the pump truck has a flat radiating structure; the flat radiating structure comprises an oil path circulating layer and an air cooling layer which are connected with each other; the oil path circulating layer comprises a plurality of parallel oil paths in which hydraulic oil flows; a channel in which the hydraulic oil flows is arranged between the adjacent oil paths; the air cooling layer comprises at least one fan and a plurality of parallel air flues; and an air outlet of the fan is opposite to the air flues. The invention also relates to a concrete pump truck with the air cooler for the pump truck, wherein the air cooler for the pump truck is served as a walking platform and is fixed on the concrete pump truck. The radiating area of the air cooler for the pump truck provided by the invention is bigger; the occupied space is small and regular; the strength of the air cooler for the pump truck is higher than the air cooler of the prior art; the pressure resistance is excellent; and the air cooler for the pump truck is mounted on the concrete pump truck in a form of the walking platform, so that the flat structure of the air cooler for the pump truck is fully utilized, the extra pump truck assembling space is not occupied, the special mounting position for the air cooler is unnecessary and the influence on the motion of moving parts is avoided.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an air cooler for a pump truck and a concrete pump truck. Background technique [0002] At present, in engineering construction, it is necessary to use a concrete pump truck to transport concrete to a designated location, and the hydraulic oil used by the concrete pump truck needs to be cooled by an air cooler. The structure of the existing air cooler is as figure 1 as shown, figure 1 The main components of the middle air cooler include an oil pipe 1, a cooling fin 2 and a fan 3. The hydraulic oil circulates through the oil pipe 1, and when the fan 3 rotates, the air flows through the heat sink 2 for heat exchange, reducing the overheated hydraulic oil. [0003] The existing air cooler needs to be installed vertically, which will occupy the limited installation space of the pump truck and easily collide with moving parts. With the development of pump truck technology, the...

Problems solved by technology

When installing the air cooler, the arrangement of the motor oil pipe and oil return pipe is also very difficult

[0004] In addition, the heat dissipation and pressure resistance of the oil pipe of the existing air cooler are average. When the hydraulic oil pressure exceeds 3MP, the pipe may break and leak oil.
