Problems solved by technology

In the related technology, when the pump truck is actually working, the working area is mostly potholes such as construction sites and fields, and the long time will cause the whole vehicle to tilt due to the soft working ground and pits, thus increasing the risk of the pump truck tipping over

Embodiment Construction

[0029] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0030] In this disclosure, unless stated otherwise, the used orientation words such as "front", "rear", "left", and "right" are usually defined by taking the pump truck as an example, specifically, the pump truck The front of the car is the front and the rear is the rear. When the driver faces the front, the left-hand side is left and the right-hand side is right. "Inside" and "outside" refer to the inside and outside of the outline of each part. The terms "first", "second" and the like used in the present disclosure are for distinguishing one element from another, and do not have order or importance. Furthermore, in the following description, when referring...

Abstract

The invention relates to a pump truck. The pump truck comprises an arm support (1), a plurality of supporting legs and a control system, wherein the arm support is hinged to a rotary table (2) througha horizontal shaft and can horizontally rotate around a vertical axis along with the rotary table (2); each supporting leg is provided with a storage device used for storing a liquid medium (4), andat least two storage devices which are arranged at intervals in the longitudinal direction of the pump truck and located on different sides in the transverse direction of the pump truck communicate with each other through a communicating pipeline and a pumping device; and the control system is used for controlling the liquid mediums (4) to flow into the storage devices on the opposite side of thearm support (1) through the pumping device in the rotating process of the arm support (1). By means of the technical scheme, the pump truck can effectively reduce the tipping risk of the pump truck and improve the stability of the pump truck.

Description

technical field [0001] The present disclosure relates to the technical field of engineering machinery, and in particular, to a pump truck. Background technique [0002] In the field of construction machinery, a pump truck is a machine that uses pressure to continuously transport raw materials along a pipeline. The pump truck is equipped with a telescopic or inflection boom, and the material is transported to the target building through the delivery pipe on the boom. During the operation of the pump truck, the larger the material distribution radius of the pump truck, the greater the overturning bending moment generated by the boom top, so the higher the risk of the pump truck tipping over. The general method for judging whether the pump truck is overturned is that when the trajectory of the center of gravity of the pump truck does not exceed the span of the outriggers, that is, when the center of gravity of the pump truck falls within the polygon formed by the support point...
