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

Abstract

The invention provides a concrete pump truck monitoring method, a concrete pump truck monitoring system and a concrete pump truck. The concrete pump truck monitoring method includes the following steps: according to the supporting positions of outriggers, the overall barycenter safety area of the concrete pump truck is calculated; according to the real-time position of a boom, the overall barycenter position of the concrete pump truck is calculated; whether the overall barycenter position is located in the overall barycenter safety area is judged; and according to a judgement result, the action of the concrete pump truck is controlled. The purpose of the invention is to provide the concrete pump truck monitoring method monitoring the concrete pump truck in real time to prevent the concrete pump truck from turning over, the concrete pump truck monitoring system and a concrete pump truck.

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 calc...
