[0002] The hydraulic station is a hydraulic source device or a hydraulic device including a control valve, which is composed of a hydraulic pump, a driving motor, an oil tank, a directional valve, a throttle valve, a relief valve, etc. The oil is supplied according to the flow direction, pressure and flow required by the driving device. It is suitable for various machines where the driving device is separated from the hydraulic station. The hydraulic station is connected to the driving device (oil cylinder or motor) with an oil pipe, and the hydraulic system can achieve various prescribed actions.

[0003] The utility model patent with patent application publication number CN 217401348 Ux discloses a low-noise hydraulic pump station, including a hydraulic station oil tank, four groups of connecting and fixing blocks are installed on the upper end of the hydraulic station oil tank, a transmission working motor is installed on the upper end of the hydraulic station oil tank, a transmission working hydraulic pump is installed on the output end of the transmission working motor, a No. 1 connecting oil pipe is installed at one end of the transmission working hydraulic pump, and a No. 2 connecting oil pipe is installed at the end of the transmission working hydraulic pump away from the No. 1 connecting oil pipe. By providing a sound insulation protective cover, a transmission working hydraulic pump and a sound insulation working baffle, the utility model has the function of reducing the working noise of the transmission working motor. When in use, the connecting and fixing block is directly inserted into the inside of the connecting and fixing slot, and the sound insulation working baffle is located at the rear end of the support and adjustment frame, and the positioning operation hole is aligned with the support and adjustment frame to complete the installation of the sound insulation protective cover and the hydraulic station oil tank, effectively reducing the noise generated when the transmission working motor is working, thereby improving the use performance.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that the device connects the oil pipe to the hydraulic pump station by opening an oil pipe connecting hole on the outer sound insulation protective shell. However, in actual use, when the operator needs to maintain, inspect and repair the inside of the hydraulic pump station, the operator is required to first remove the oil pipe and then remove the outer sound insulation protective shell from the hydraulic pump station. The operation is very troublesome and it is easy to cause the outflow of hydraulic oil to pollute and waste the hydraulic pump station.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0029] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0030] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0044] Thus, the operator can pull the handle 38 to drive the sliding block 35 to slide out of the sliding limit groove 31. The sliding of the sliding block 35 drives the sliding plate 34 to slide and disengage the first magnetic block 32 and the second magnetic block 36, so that the silent cover 25 can move upward to facilitate the operator to maintain and overhaul the hydraulic pump station assembly 1. After the maintenance and overhaul is completed, the operator pushes the handle 38 again to make the sliding block 35 and the sliding plate 34 slide inward until the first magnetic block 32 and the second magnetic block 36 are adsorbed again, and the sliding plate 34 and the silent cover 25 are connected and fixed, and the connecting oil pipe 15 is limited by the first arc hole 33 and the second arc hole 37.
