Concrete pump truck monitoring method, concrete pump truck monitoring system and concrete pump truck

Abstract

A concrete pump truck monitoring method, a concrete pump truck monitoring system, and a concrete pump truck. The concrete pump truck monitoring method comprises the following steps: calculating a center-of-mass safe area (80) of an entire concrete pump truck based on support positions of support legs (71, 72, 73, 74); calculating a center of mass of the entire concrete pump truck based on real-time positions of booms (61, 62, 63, 64, 65); determining whether the center of mass of the entire truck is in the center-of-mass safe area (80) of the entire truck; controlling actions of the concrete pump truck based on a determination result. The method monitors the pump truck in real time to prevent the pump truck from tipping.

Description

technical field [0001] The invention relates to the technical field of concrete pump truck monitoring, in particular to a concrete pump truck monitoring method, a concrete pump truck monitoring system and a concrete pump truck. Background technique [0002] Wheeled construction machinery, such as concrete pump trucks, need to expand the outriggers before construction to ensure the safe distribution of the boom. However, due to the limitation of the construction site, often the outriggers cannot be fully deployed, and at this time, there is a great potential safety hazard in the boom's cloth operation. During actual construction, equipment overturning accidents frequently occur due to the incomplete expansion of the outriggers, which is one of the main reasons for the safety accidents of concrete pump trucks. [0003] In order to overcome this defect, a pump truck with X-shaped outriggers was invented, which can only expand one side of the outrigger for support, but the use ...

Problems solved by technology

When the pump truck is in use, the control system can only identify the two working conditions of fully extended outriggers or unilaterally extended outriggers, so as to monitor the rotation of the boom safely. Under the two working conditions, the rotation angle of the boom is 0 to 360° and 0 to 130°, and when the outriggers are in a certain unfolded position between the two working conditions, the control system cannot calculate the safe range of movement of the boom, which greatly limits the safe working range of the pump truck

[0004] In order to expand the cloth range of the jib when the outriggers are not fully deployed, the patent document CN102248933A proposes a method for determining the swivel angle of the jib by calculating the expansion range of the outriggers through sensor detection. The main limitation of this patent is that when the jib outriggers are known coordinates, only the minimum safe working range of the boom rotation can be determined, and the calculation of the maximum safe cloth distribution range cannot be realized, which makes the working range of the boom cover incomplete and limits the safe working range of the pump truck

When limited by the construction site, the unilateral support of the outriggers cannot be fully expanded. At this time, according to the method provided by the patent document, the rotation angle of the safe working range of the boom is very small, almost 0°, and the pump truck cannot work here. fabric work
