Problems solved by technology

However, if the outriggers of the pump truck extend a long distance, it will inevitably occupy a larger site. In the case of limited construction sites, the outriggers of the pump truck cannot be extended according to the stability requirements, and the stability requirements of the vehicle body cannot be met.
In addition, since the stability depends to a certain extent on the length of the outriggers, it is necessary to process longer outriggers, which increases the weight of the car body and the cost of production

Abstract

The invention discloses a concrete pump truck which comprises an underpan, a boom system and middle component arranged between the underpan and the boom system. The middle components comprise a fixed turret arranged on the underpan and a first swing mechanism arranged between the fixed turret and the boom system, a rail is arranged on of the fixed turret and the first swing mechanism, the other one of the fixed turret and the first swing mechanism operates along the rail, and the first swing mechanism is enabled to drive the boom system to move horizontally relative to the fixed turret. The boom system of the concrete pump truck not only can rotate, but also can operate relative to the fixed turret to enable the length and the width of an arm support to be adjusted flexibly.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a concrete pump truck. Background technique [0002] The concrete pump truck includes a chassis and a bodywork, and the bodywork includes a fixed turret and a jib system. The fixed turret is fixed on the chassis, the side of the fixed turret is used to connect the outriggers, a slewing mechanism is set above the fixed turret, the boom system is set on the turntable, the slewing mechanism drives the turntable to rotate relative to the fixed turret, and then drives The boom rotates relative to the chassis. [0003] The operating range of the concrete pump truck depends on the extended length of the boom. Based on the constraints of control sensitivity, boom strength and other factors, the overall length of the boom is limited, and the operating range of the boom cannot be effectively obtained on the basis of the current boom structure. Expansion, unable to meet some...
