Abstract

The invention discloses a weighting device and a working method for mining self-discharging vehicle. The device comprises an effective load capacity gauge, a hanging device pressure sensor, a display screen, a state display lamp and a signal input device. The signal input device comprises a compartment lifting switch, a speed sensor, an accelerating pedal sensor, a loading braking switch, an electric braking switch and a working braking switch. The effective load capacity gauge comprises a micro processor, a logic programming controlling circuit, an electric erasable programmable reading-only memory and a communication port. The effective load capacity gauge has the functions of real-time computing, controlling, storing, communicating, displaying and the like. The effective load capacity of the self-discharging vehicle under various conditions is recorded. Accurate weighting is achieved and overloading is avoided. Vehicle operating data are recorded and data real time communication and transmission are conducted with outer equipment or an outer system. The weighting device and the working method for mining self-discharging vehicle is provided with the ability of autonomously recognizing operating state. And accuracy of the measured effective load capacity is guaranteed.

Description

technical field [0001] The invention relates to a weighing device, in particular to a mining dump truck weighing device and its working method. Background technique [0002] At present, mining dump trucks have been widely used in large-scale open-pit mine transportation and water conservancy construction. The loading monitoring of mining dump trucks and the collection and recording of vehicle operation data are beneficial to mine production management, and have the functions of avoiding vehicle overload, improving economic benefits and reducing costs. Due to the limitations of the working conditions of this type of vehicle, weighing by scales can no longer meet the needs of fleet operations, and the method of installing weighing sensors at the bottom of the compartment for weighing cannot solve the main problem of recording vehicle operating data. Due to the huge annual carrying capacity of this type of vehicle, it is obviously necessary to achieve accurate measurement. C...
