Embodiment Construction

[0019] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0020] figure 2 is a flow chart of a pump truck control method according to an embodiment of the present invention, such as figure 2 As shown, the method includes the following steps S102 to S112:

[0021] Step S102, acquiring the opening degrees of the four outriggers of the pump truck.

[0022] In this step, the opening of the outrigger is measured in real time by the outrigger sensor including the pull wire and the angle sensor, image 3 is a schematic diagram of pump truck control according to an embodiment of the present invention, such as image 3 As shown, including measuring the opening of the two front X legs 1 and the two rear swing legs 2.

[0023] Step S104, determine the bou...

Abstract

The invention discloses a pump truck and a control method and a device thereof. The pump truck control method comprises the steps that: the opening of the four support legs of the pump truck is obtained; the tail end points of the four support legs of the pump truck are determined according to the opening, and the tail end points of the four support legs are connected to determine the safe operation surface boundaries of the pump truck; the complete truck stable center of the pump truck is calculated according to the unloading gravity of the pump truck, a downloading barycentric coordinate and the complete truck gravity of the pump truck; the safety factor of the pump truck is calculated according to the unloading gravity of the pump truck, the arm frame gravity of the pump truck and the complete truck gravity of the pump truck, the arm frame barycentric coordinate of the pump truck and the downloading barycentric coordinate of the pump truck; and the pump truck is controlled according to the safety factor. The invention can ensure the safety of the pump truck when the support legs of the pump truck cannot be fully unfolded.

Description

technical field [0001] The invention relates to the field of pump trucks, in particular to a pump truck and its control method and device. Background technique [0002] The safety of concrete pump trucks in the construction process is a key technical issue. At present, the pump truck is to fully open the outriggers to ensure the maximum safe working surface, such as figure 1 As shown, the concrete delivery radius of the pump truck can be maximized to ensure that the pump truck can safely pump concrete under the horizontal posture of the boom. However, due to the limitation of the working space, the outriggers often cannot be fully extended, which limits the safe delivery radius of the pump truck, and thus cannot guarantee the safety of the pumping state of the boom in any posture. There is a danger of the vehicle tipping over. Without fully opening the outriggers, how to dynamically determine the safe working range of the pump truck, so as to limit the movement of the boo...
