Abstract

The invention discloses a dump truck power take-off safety control system and method, including a power take-off, a safety control module, a power take-off control switch, an engine speed sensor, an engine ECU, an alarm device, and a display; the power take-off The output shaft is connected with the gear pump of the hydraulic lifting system; the safety control module is respectively connected with the control switch of the power take-off, the alarm device and the display. A dump truck power take-off safety control system and method provided by the present invention can ensure the safety of the dump truck in the process of lifting the compartment, and can use the speed of the gear pump of the hydraulic lifting system to limit the speed of the engine to improve the safety of the dump truck. Service life of unloading truck.

Description

technical field [0001] The invention belongs to the technical field of dump trucks, and in particular relates to a safety control system and method for a dump truck power take-off. Background technique [0002] At present, when the driver is lifting or lowering the dump truck, he turns on the power take-off by turning on the electric control switch or the air control switch of the power take-off, and drives the hydraulic system to realize the lifting or lowering of the carriage. Manual operation control is relatively simple, but lacks safety, and also lacks an alarm prompt for abnormal work. Contents of the invention [0003] In order to overcome the above-mentioned technical problems existing in the prior art field, the object of the present invention is to provide a dump truck power take-off safety control system and method, which can intuitively reflect the working state of the power take-off, and can limit the continuous increase of the engine speed, and then Limit th...
