It is lifted using two oil cylinders, the reasonable design for providing the power unit oil circuit of power is extremely important.
Utility model content
Purpose of the utility model is to solve above-mentioned existing defect, provide that a kind of integrated degree of part is high, body
Small, the better scissor-type lifting platform power unit of lifting platform stability of product.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of scissor-type lifting platform power unit, including centre valve block, be fixed on centre valve block both ends fuel tank and
Motor, the gear pump for being connected with fuel sucking pipe on the end face of centre valve block in fuel tank and returning set on centre valve block left side wall
Oil pipe opens up oil circuit in the centre valve block, it is characterised in that:The centre valve block right side wall installation check valve, 3-position 4-way
Solenoid valve, in-line is connected to three position four-way electromagnetic valve to A working holes and B working holes after check valve and is formed in the centre valve block
The lifting oil circuit of executive component.
Overflow valve is installed as a preferred technical solution, the overflow valve is located at a centre valve block left side in the centre valve block
On the oil return line of side wall.
The three position four-way electromagnetic valve is superposing type three position four-way electromagnetic valve as a preferred technical solution,.
The centre valve block is made of aluminum alloy materials as a preferred technical solution,.
The beneficial effects of the utility model are：The stability of lifting platform operation, the integrated degree height of part, volume can be promoted
It is small, meanwhile, it assembles and operates and is more convenient.
