Embodiment Construction

[0014] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, a control system for preventing the self-lifting of the cargo box during the running of the dump truck includes an interconnected power take-off control circuit and a parking brake air circuit. The power take-off control circuit is composed of a low pressure switch 5, The power take-off rocker switch 6, the power take-off indicator light 7, the position switch 8 and the battery 9 are composed of the low air pressure switch 5, the power take-off seesaw switch 6 and the battery 9 are electrically connected in sequence, and the positive pole of the battery 9 is It is electrically connected to the position switch 8, one end of the position switch 8 is electrically connected to the power take-off indicator light 7, the other end of the power take-off indicator light 7 is grounded, and the negative pole of the battery 9 is grounded; the par...

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...
