Abstract

The invention discloses a dumper and a lifting control device thereof. The lifting control device comprises a lifting cylinder, a first reversing valve, a second reversing valve, a third reversing valve and a controller. When the controller receives a lifting instruction, the controller controls the second reversing valve to be switched from the right position to the left position, the air inlet connector is communicated with a control connector of the first reversing valve so as to control the first reversing valve to slide through the air inlet connector, the first reversing valve is switched from the middle position to the right position, oil enters the lifting cylinder, a piston rod extends outwards, and lifting is achieved. When the controller receives a falling instruction, the controller controls the third reversing valve to be switched from the right position to the left position, the air inlet connector is communicated with the control connector of the first reversing valve so as to control the first reversing valve to slide through the air inlet connector, the first reversing valve is switched from the middle position to the left position, the lifting cylinder returns oil, and falling is achieved. The lifting cylinder can be automatically controlled to ascend and descend, and operation is convenient.

Description

technical field [0001] The invention relates to the field of dump trucks, in particular to a dump truck and a lifting control device thereof. Background technique [0002] The hopper of the dump truck can be turned over by the lifting cylinder, which is convenient for unloading and is widely used. There is usually an operating handle in the cab of the dump truck, and the operating handle is used to adjust the position of the spool of the reversing valve, so that the reversing valve controls the lifting of the lifting cylinder with the help of the hydraulic pipeline. When the operating handle in the cab is pushed to the "lift" position, and the power take-off switch is turned on at the same time, the gear pump starts to work, and the hydraulic oil in the hydraulic oil tank is pressurized by the gear pump, passes through the reversing valve, and then flows into the lift cylinder. Cavity, push the piston rod, so that the carriage starts to lift. After lifting to the maximum p...
