A dump truck remote control system and a dump truck remote control operation method

Abstract

The invention discloses a dumper remote control system and a dumper remote control operation method. The dumper remote control system comprises a lifting hydraulic pipeline which comprises a lifting hydraulic oil cylinder. The dumper remote control system further comprises an electric control gas circuit hydraulic valve, a wireless remote control unit and a wireless receiving controller. The electric control gas circuit hydraulic valve is provided with a coil, connected with the lifting hydraulic pipeline and connected with a gas circuit limiting valve in series. The wireless remote control unit is provided with multiple keys. The wireless receiving controller is connected with the wireless remote control unit in a radio frequency communication manner and connected with the electric control gas circuit hydraulic valve and can output multiple ways of signals to the electric control gas circuit hydraulic valve. By the adoption of the dumper remote control system, an operator can complete ascending and descending actions of a carriage through the wireless remote control unit in the man and dumper separating state, and the system is safer and more convenient.

Description

technical field [0001] The invention relates to the field of dump trucks, in particular to a dump truck remote control system and a dump truck remote control operation method. Background technique [0002] So far, the lifting operation of the dump truck body is all performed by manually operating the mechanical handle of the mechanical air control valve in the cab to perform lifting, lowering, slow lowering, and mid-stop actions, and then transmits the air circuit control signal to the air control valve. The hydraulic valve outputs hydraulic oil to control the expansion and contraction of the lifting hydraulic cylinder, and finally realizes the lifting, lowering, stopping and slow lowering of the dump truck body. This method improves the performance and work efficiency of the equipment, but because the operator needs to operate in the cab, the operator can only check the environment around the vehicle by observing the rearview mirror during the lifting operation of the dump ...

AI Technical Summary

Problems solved by technology

However, these remote control system solutions cannot better meet people's usage habits. It is necessary to make a special remote control transmitter and receiver for dump trucks for dump truck lifting operations.

[0004] The existing lifting control method of the dump truck leads to the low integration of the entire lifting control system of the dump truck, and it is troublesome to lay out the pipeline. On the premise of introducing the remote control method of the dump truck, the electric control, air control and hydraulic control are integrated into the Together, it adopts the form of combined valve, and retains the mechanical control method and self-protection mechanism. When the remote control system is powered off, the work can be completed by manual operation, and the safety limit protection continues to be effective, forming a mechanical and electrical-hydraulic integrated control. system becomes an inevitable requirement
