Chassis engine power takeoff short arm support concrete pump truck

Abstract

The invention discloses a chassis engine power takeoff short arm support concrete pump truck which is composed of a pump truck chassis and an engine. The chassis engine power takeoff short arm support concrete pump truck is characterized in that a power takeoff is arranged on the engine, one end of a transmission shaft is connected with the power takeoff, the other end of the transmission shaft is connected with a main oil pump, an arm support pump and stirring, washing and cooling pumps which are connected in series, the main oil pump is connected with and controls a first main oil cylinder, a second main oil cylinder, a first tilt cylinder and a second tilt cylinder through main valve blocks, and the arm support pump and the stirring, washing and cooling pumps are respectively connected with and control corresponding systems. The chassis engine power takeoff short arm support concrete pump truck has the advantages of being simple in structure, low in cost, convenient to install and maintain and capable of meeting performance requirements.

Description

technical field [0001] The invention belongs to the technical field of short-arm concrete pump truck power systems, and in particular relates to a short-arm concrete pump truck with power taken from a chassis engine. Background technique [0002] At present, the chassis power take-off method used by domestic short-boom pump trucks is transfer box type connection power take-off. This power take-off method has stable performance, but it is inconvenient to install and modify the chassis, and the chassis drive shaft needs to be refitted. , After refitting, it is necessary to carry out a dynamic balance test on the transmission shaft, and the general concrete pump truck manufacturer does not have a dynamic balance test bench, which causes a lot of inconvenience to the manufacturer; at the same time, the current power system includes a transfer case, various The connecting parts of the oil pump and the hydraulic system have a relatively complicated structure, and they are all loca...

Problems solved by technology

[0002] At present, the chassis power take-off method used by domestic concrete short-boom pump trucks is transfer box type connection power take-off. This power take-off method has stable performance, but it is inconvenient to install and modify the chassis, and the chassis transmission shaft needs to be refitted. After refitting, it is necessary to carry out a dynamic balance test on the transmission shaft, and the general concrete pump truck manufacturer does not have a dynamic balance test bench, which causes a lot of inconvenience to the manufacturer; at the same time, the current power system includes a transfer case, various The connecting parts of the oil pump and the hydraulic system have a relatively complicated structure, and they are all located under the chassis of the concrete pump truck, which is very inconvenient for maintenance and maintenance.
