A control device for preventing the carriage of a dump truck from self lifting comprises a power take-off switch K1, an ECU (electrical control unit), a vehicle speed signal sensor BN and a carriage lift sensor BS, the two ends of the power take-off switch K1 are connected with a power supply anode and a switching signal input end of the ECU, the speed signal output end of the vehicle speed signal sensor BN is connected with the vehicle speed signal input end of the ECU, the control signal output end of the ECU is connected with a power supply negative pole through a power take-off electromagnetic valve V, and the output end of the carriage lift sensor BS is connected with a loudspeaker SP, a power take-off indicator light LED 1 and the lift signal input end of the ECU. Due to the adoption of the design, the phenomenon of self lifting of a dump body, caused by misoperation can be prevented, and carriage lifting for operation when the dump truck drives at a low speed is achieved.
Description
technical field [0001] The invention relates to a dump truck safety device, in particular to a control device for preventing the self-lifting of the dump truck compartment, which is particularly suitable for lifting the compartment when the dump truck is running at a low speed, and prompting the driver of the compartment lifting state. Background technique [0002] The dump truck compartment needs to be lifted only under certain circumstances. If the compartment is accidentally lifted when driving at high speed or in other environments where the compartment is not allowed to be lifted, it will cause safety accidents, ranging from property damage to life-threatening Safety. [0003] The Chinese patent authorization announcement number is CN201610115U, and the utility model patent whose authorization announcement date is October 20, 2010 discloses a control circuit for the safe operation of power take-off of dump vehicles, which includes a power take-off operation switch K3 an...
