[0031] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0032] In actual application, the staff starts the motor to drive the gear pump 405 to work, sucks hydraulic oil from the cylinder 408, and outputs the oil after pressurization through the rotation of the gear. The pump station 407 is used as a power unit to uniformly distribute the output oil of the gear pump 405 to the hydraulic circuit. The hydraulic oil pressurized by the gear pump 405 flows into the system through the one-way valve 404 to prevent the oil from flowing back and maintain the pressure of the system stable. At the same time, the solenoid valve 402 receives the electronic control signal to control the flow direction of the hydraulic oil and realize the switching of different lifting, lowering and stopping. The solenoid valve 402 is opened, and the hydraulic oil flows into the cylinder 408 to push the active The plug rod 409 rises to lift the transport fork frame 1 and elevate the transport fork frame 1 to the required height for transporting the goods.

At the same time, the distance between the baffle 1 304 and the baffle 2 308 can be adjusted according to the number of goods to be transported, so that the cargo limit in different transportation situations can be met, thereby improving the efficiency of transportation. The utility model sets an integrated pump 4 and uses the cylinder valve plate 401 as the core component of oil circuit distribution and control, so that the various components are effectively connected, the integrated layout of the oil circuit is convenient, the oil pipe connection points are reduced, the leakage risk is reduced, the oil pipe and steel pipe connection is eliminated, the oil leakage hidden danger is reduced, and the assembly also reduces the wiring length of the harness.
