Abstract

The invention discloses a safety protection type oil cylinder device. The safety protection type oil cylinder device comprises a lifting oil cylinder, a fixed column, an oil outlet, a push rod, a protection mechanism, an oil returning port, a valve block and a two-position two-way electromagnetic valve. According to the safety protection type oil cylinder device, the two-position two-way electromagnetic valve is installed on the valve block which is installed on the oil returning port of the lifting oil cylinder; then two wires carried by itself are connected to a valve group controlling oil returning of the oil cylinder; when the electromagnetic valve is powered on, two-position two-way circulating is achieved; when the electromagnetic valve is powered off, two-position two-way closing isachieved; when a hydraulic pipeline bursts instantly, hydraulic oil in the oil cylinder can be prevented from leaking, and it is guaranteed that a box body cannot fall instantly; and a protection mechanism is arranged, the valve block is effectively protected during pipeline bursting, and falling or position deviating caused under the pressure bearing effect is prevented.

Description

technical field [0001] The invention relates to the related field of dump truck accessories, in particular to a safety protection type oil cylinder device. Background technique [0002] A dump truck is a vehicle that unloads goods by itself through hydraulic or mechanical lifting, also known as a dump truck. It is composed of a car chassis, a hydraulic lifting mechanism, a cargo compartment, and a power take-off device. The instantaneous burst of the pipeline causes the lifting cylinder to unload the oil, and the phenomenon of causing the tank to drop is all using a safety support device. [0003] Some safety support devices of large vehicles are inconvenient to operate, and some are bulky. Therefore, whether it is in the assembly process or the maintenance process, the operators will always take chances and will not support the safety support device, resulting in existence Security risks. Contents of the invention [0004] Therefore, in order to solve the above disadvan...
