Embodiment 1

[0024] Integrated hydraulic system, such as Figure 1-Figure 6 As shown, the base plate 1 is included, the base plate 1 is fixed with a fuel tank 2 and an oil cylinder 4 connected to the fuel tank 2 through a two-way oil pipe 3, a gear pump 5 is arranged in the fuel tank 2, and a motor 6 connected with the gear pump 5 is installed on the fuel tank 2. The two-way oil pipe 3 means that the oil cylinder 4 can realize oil feeding into the oil cylinder 4, and can return the oil in the oil cylinder 4 to the oil tank 2.

[0025] Fix the oil tank 2 and the oil cylinder 4 on the bottom plate 1, and connect them only through a two-way oil pipe 3 to form an integrated valve body, which serves as an actuator; pass the motor 6 and the gear pump 5 through Bolts are connected to the one-piece valve body to make it a power unit, and there is no pipe connection between the actuator and the power unit, so that the actuator and the power unit of the system are integrated into a whole, which grea...

Abstract

The invention relates to hydraulic systems and discloses an integrated hydraulic system. The integrated hydraulic system comprises a bottom plate (1). An oil tank (2) and an oil cylinder (4) connected with the oil tank (3) through a bidirectional oil pipe (3) are arranged on the bottom plate (1). A gear pump (5) is arranged in the oil tank. A motor (6) connected with the gear pump (5) is installed on the oil tank. The oil tank (2) is provided with a one-way valve (7) for controlling connection and disconnection of the bidirectional oil pipe (3) and a hand-operated valve (8) for acting on the one-way valve (7) to make the one-way valve (7) be opened. The oil tank (2) is further provided with an overflow valve (9). According to the integrated hydraulic system, a power unit and an execution mechanism are integrated, so that the size of the whole system is effectively reduced, and the cost is lowered. Because the whole system has no pipeline or joint connection, hydraulic leakage and pollution are avoided as much as possible, and the hydraulic system is made more reliable and stable.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to an integrated hydraulic system which integrates a hydraulic power unit, a control unit and an actuator as a whole to realize lifting. Background technique [0002] The hydraulic system generally consists of three parts: the hydraulic power unit, the control unit and the actuator. The hydraulic system is an important part of the truck. Its performance and cost are directly related to the market prospect and promotion of the whole machine, especially Today, when the truck is becoming lighter and cheaper, the cost and size of the hydraulic power unit become more critical. [0003] At present, the pallet truck lifting system used in the logistics industry can be roughly divided into two categories: manual and electric. The manual pump system is simple and compact in structure and low in price, but it is very laborious to operate the manual pump solely by manpower, so the load should not be too l...
