Concrete pump truck intelligent arm support control system and control method thereof

Abstract

The invention provides a concrete pump truck intelligent arm support control system and a control method thereof. The control system comprises an arm support, a controller, an operating device and an actuator. The control system is characterized in that the control system also comprises an arm support detecting device which is used for detecting the spatial location of each segment of the arm support and transmitting detected spatial location signals of each segment of the arm support to the controller. The control method comprises: the construction of an arm support coordinate system; the detection of the current arm support position; the control of the actions of the arm support. In the concrete pump truck intelligent arm support control system, an operator is not required to manually regulate the position the gyratory angle of each segment of the arm support, the pouring accuracy and the operational reasonability are guaranteed, and the construction efficiency and the whole service life of the truck are improved greatly; within the stress impact allowable range and on the basis of the consideration of the concrete fluidity, coordinated actions of a plurality of segments of the arm support are realized; simultaneously, during the controlling process, extreme conditions and unreasonable operations of the movements of a plurality of the segments of the arm support are limited, the labor intensity and the experience requirement of the operator are alleviated greatly, and influences of unreasonable operations on the arm support structure and the service life of a hydraulic system are avoided.

Description

Technical field: [0001] The invention relates to a boom control system in the field of engineering machinery, in particular to an intelligent boom control system for intelligent distribution of concrete pump trucks with a special controller as the core, which can be applied and promoted on construction machinery with a boom device. Background technique: [0002] The tire-type concrete pump truck is a typical construction machine with a multi-stage boom. The basic process of its construction is to pour concrete through the distribution pipe on the boom through the hydraulic pumping mechanism of the body, and pour it on the construction site according to the operation requirements of the operator, and control its pouring position. In fact, it controls the position of the end of the boom. to achieve. [0003] The early concrete pump trucks had a short overall length of the boom, a small number of boom sections, and poor control technology. They were basically fixed, and the en...

Problems solved by technology

like image 3 As shown, moving the end position E of the boom to E' requires at least the combined action of the penultimate first and second two booms. If only one of the booms is manipulated, it is impossible to achieve the desired effect, and the control is difficult and the control Not in place, low efficiency and other defects
