Real-time detection method and real-time detection device of mixer truck unloading flowrate

Abstract

The invention relates to a real-time detection method and a real-time detection device of mixer truck unloading flowrate. The detection method comprises the following steps: monitoring and acquiring concrete thickness at a distance reference point 1 on a center line of a chute of a mixer truck as well as an included angle between the chute and the horizontal surface in real time; inputting the concrete thickness and the included angle between the chute and the horizontal surface into a controller; arranging a mixer truck unloading flowrate mathematical model in the controller in advance, wherein the mixer truck unloading flowrate mathematical model is related to the concrete thickness, the included angle between the chute and the horizontal surface, as well as an interval between a concrete thickness sensor and a reference point; according to the inputted concrete thickness as well as the included angle between the chute and the horizontal surface, calculating the mixer truck unloading flowrate by the mixer truck unloading flowrate mathematical model; and outputting the mixer truck unloading flowrate from the controller. The method and the device are capable of detecting the mixer truck unloading flowrate in real time; according to the detected flowrate value, a pump truck can be matched with pumping power to achieve an energy-saving effect.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a method and device for real-time detection of the unloading flow of a mixer truck. Background technique [0002] The chute is a device used in the mixer truck to guide the concrete from the outlet to the pump truck inlet hopper and other designated locations. Currently on the market, when the pump truck is pumping concrete, it still relies on human experience to manually adjust the displacement of the pump. However, the operation method of manually adjusting the pump displacement has no reliable data as the basis for adjustment, so the manual adjustment method is too subjective. When the discharge flow of the mixer truck changes, the pump truck cannot make corresponding adjustments, which will lead to excessive fuel consumption and waste. Similarly, when the concrete demand of the pump truck changes, since there is no standard for adjusting the unloading flow of the mixer...

However, the operation method of manually adjusting the pump displacement has no reliable data as the basis for adjustment, so the manual adjustment method is too subjective

When the discharge flow of the mixer truck changes, the pump truck cannot make corresponding adjustments, which will cause excessive fuel consumption and waste

Similarly, when the concrete demand of the pump truck changes, since there is no standard for adjusting the unloading flow of the mixer truck, and it is not known what the best matching flow is, the flow will often be too large or too small, which will easily cause energy consumption. waste, and it is not conducive to the efficient and safe work of the pump truck
