An explosion-proof dump truck with a lifting protection device

Abstract

The invention discloses an anti-explosion dump truck with a lifting protective device. The structure comprises a hydraulic lifting oil cylinder, a driving chamber, marching wheels, a bearing chassis,a support pressure-bearing device and a hopper, the bottom of the bearing chassis is provided with the support pressure-bearing device, and the upper and lower ends of the support pressure-bearing device are respectively fixed to the hopper and the bearing chassis; the support pressure-bearing device is arranged between the hopper and the bearing chassis, when the hydraulic lift oil cylinder is inthe lifting process, the support pressure-bearing device can improve the stability of hopper unloading to avoid truck leaning and rollover, when the hopper needs descending, the bump degree between the hopper and the bearing chassis can be buffered, thereby greatly prolonging the service life of the bearing chassis, and reducing the bearing strength of the wheels, when the hopper overloads, an alarm can output overload information to the driving chamber through electrical signals so as to remind a driver of the overload situation.

Description

technical field [0001] The invention relates to an explosion-proof dump truck with a lifting protection device, which belongs to the field of explosion-proof dump trucks. 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] The compartment of a dump truck is divided into two types: backward tipping and sideways tipping. The movement of the piston rod is controlled by the operating system. Backward tipping is more common. [0004] In the prior art explosion-proof dump truck, when the cargo compartment drops to a certain height during the hydraulic lifting process, the mutual buffer between the chassis and the cargo compartment cannot be realized, thereby improving the service life of the chassis and reducing the load-bearing strength of ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an explosion-proof dump truck with a lifting protection device to solve the problem that the explosion-proof dump truck cannot realize the gap between the chassis and the cargo compartment when the cargo compartment drops to a certain height during the hydraulic lifting process. Mutual buffering between them, thereby improving the service life of the chassis and reducing the load-bearing strength of the wheels, and the problem that the alarm cannot be issued when the cargo compartment is overloaded
