Abstract

The invention discloses a control system preventing a cargo box from automatic lifting during a dumper running. The control system comprises a power take-off controlling circuit and a parking braking air circuit which are connected. The power take-off controlling circuit is composed of a low-pressure switch, a power take-off rocker switch, a power take-off indicator light, a positioning switch and an accumulator. The parking braking air circuit is composed of an air cylinder, a manual valve, a solenoid valve, a power take-off control cylinder, a relay valve, a spring energy storage air chamber, a front brake air chamber and a foot brake valve. The control system has the advantages that the power take-off is controlled by the low-pressure switch to control the circuit, thus fundamentally solved is the problem that during the dumper running, maloperation occurs to the power take-off rocker switch to cause automatic lifting of the cargo box.

Description

technical field [0001] The invention relates to the technical field of dump trucks, in particular to a control system for preventing self-lifting of cargo boxes when the dump truck is running. Background technique [0002] A dump truck is a vehicle that unloads goods by itself through hydraulic or mechanical lifting. Also known as dump truck. It is composed of automobile chassis, hydraulic lifting mechanism, cargo compartment and power take-off device and other components. [0003] In civil engineering, dump trucks are often combined with construction machinery such as excavators, loaders, and belt conveyors to form a loading, transporting, and unloading production line for loading and unloading of earthwork, sand, and bulk materials. [0004] At present, some serious traffic accidents have been caused by the self-lifting of the dump truck without the driver's knowledge due to misoperation and other factors during the driving process. In view of the above situation, many m...
