Dump truck lock hook misoperation prevention control circuit and device and dump truck

Abstract

The invention discloses a dump truck lock hook misoperation prevention control circuit and a device and a dump truck, and relates to the technical field of vehicles. The dump truck lock hook misoperation prevention control circuit comprises a latch hook travel switch module, a buzzer and a control module, the latch hook travel switch module receives a lifting signal, generates a closing signal according to the lifting signal when the latch hook is in a working state and sends the closing signal to the control module, and the control module receives the closing signal, controls carriage liftingstopping according to the closing signal; the latch hook travel switch module generates an alarm signal according to the lifting signal and sends the alarm signal to the buzzer when the latch hook isin a working state, the buzzer receives the alarm signal and gives a latch hook misoperation alarm according to the alarm signal, and when the latch hook is unloaded, carriage lifting is stopped automatically. The accident that a rear door of the carriage is damaged or the whole dump truck overturns is avoided, and the buzzer gives an alarm to remind a user of troubleshooting in time, so that theworking efficiency of the dump truck is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a dump vehicle anti-lock hook misoperation control circuit, a device and a dump vehicle. Background technique [0002] Dump truck is a special vehicle that uses its own engine power to drive hydraulic lift, tilts its compartment to a certain angle to unload, and relies on the weight of the compartment to reset it. At present, most of the back doors of dump trucks on the market are composed of an automatic locking mechanism and a locking hook.
