[0002] The hydraulic station is a hydraulic source device or a hydraulic device including control valve which is composed of hydraulic pump, driving motor, oil tank, directional valve, throttle valve and overflow valve. The hydraulic station oil change device is a device for oil change of the hydraulic station. In the whole oil change process, the old oil in the oil tank needs to be discharged, and then new oil is injected into the oil tank. At the same time, the hydraulic oil needs to be kept clean to ensure the normal operation of the hydraulic system.

[0003] The hydraulic oil in the oil tank of the hydraulic station is easy to mix with impurities during long-term use. These impurities will precipitate in the oil tank. In the oil change process of the oil tank, the sludge and other impurities precipitated at the bottom of the oil tank are difficult to be discharged with the old oil at one time, and need to be cleaned manually for the second time. In this way, not only the operation is troublesome, but also the manual cleaning is easy to cause damage to the inner wall of the oil tank due to improper operation, affecting the service life of the oil tank.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example: Reference Figures 1-5 The hydraulic station oil changing device shown includes a base 1, on which multiple shock absorbers 2 are installed. A support plate 3 is installed on the top of the multiple shock absorbers 2. A first U-shaped seat 4 is fixed on the upper surface of the support plate 3. A carrier pipe 5 is rotatably connected between the front and rear inner walls of the first U-shaped seat 4 by a pin. A fixing block 6 is fixed on the outer wall of the carrier pipe 5. A clamping assembly is installed on the top of the fixing block 6. The clamping assembly is used to lift and clamp the hydraulic station oil tank. A second U-shaped seat 7 is installed on both the clamping assembly and the support plate 3. A sleeve 8 is rotatably connected between the front and rear inner walls of the second U-shaped seat 7 by a pin. A first hydraulic cylinder 9 is installed between the two sleeves 8. A vibration motor 10 is installed on the upper surface of the support plate 3. An oil filter assembly is installed on the base 1. The oil filter assembly is used to filter the old oil and send the filtered old oil back to the inside of the hydraulic station oil tank.

[0023] The hydraulic station oil tank is lifted and clamped by the clamping assembly. The oil tank's drain valve is opened. The old oil discharged from the oil tank is carried by the oil filter assembly. The oil filter assembly can perform simple filtration on the old oil and send the filtered old oil back into the oil tank. The first hydraulic cylinder 9 is activated to pull the oil tank to swing around the carrier pipe 5. In this way, the filtered old oil can be used to flush the inner wall of the oil tank, causing the sludge and other impurities that have settled inside the oil tank to be discharged with the old oil.

[0024] After new oil is injected into the hydraulic station's oil tank, the vibration motor 10 can be activated to drive the oil tank to vibrate, accelerating the removal of air bubbles in the new oil inside the tank. This allows for a more accurate determination of the amount of new oil injected, which is beneficial for the subsequent use of the hydraulic station. Multiple shock absorbers 2 can work in conjunction with the vibration motor 10 to better assist in the vibration of the oil tank.

[0025] The clamping assembly includes a U-shaped plate 11, a fixing block 6, and a second U-shaped seat 7, all of which are fixedly installed at the bottom of the U-shaped plate 11. A second hydraulic cylinder 12 is installed on the left side of the U-shaped plate 11, and a clamping plate 13 is fixedly installed at the output end of the second hydraulic cylinder 12. A reserved groove is opened on the right side of the U-shaped plate 11, and the oil filter assembly is located directly below the reserved groove. The oil drain valve of the hydraulic station oil tank corresponds to the reserved groove, and the reserved groove is used to assist in draining oil from the hydraulic station oil tank.

[0026] The hydraulic station oil tank is hoisted onto the U-shaped plate 11 using a crane. The second hydraulic cylinder 12 is then activated to push the clamping plate 13 to move, so that the clamping plate 13, together with the U-shaped plate 11, firmly clamps the hydraulic station oil tank, facilitating subsequent operations on the oil tank.

[0027] The oil filtration assembly includes an oil receiving tank 14, which is mounted on the base 1 and located directly below the reserved slot. A filter plate 15 is installed inside the oil receiving tank 14, and an oil pump 16 is installed on the outside of the oil receiving tank 14. The oil inlet of the oil pump 16 is fixedly connected to an oil inlet pipe 17, and the bottom end of the oil inlet pipe 17 extends to the bottom of the filter plate 15. The oil outlet of the oil pump 16 is fixedly connected to an oil delivery pipe 18, and a drain pipe 19 is fixedly connected to the oil receiving tank 14. A valve is installed on the drain pipe 19. Opening the valve on the drain pipe 19 can discharge the old oil in the oil receiving tank 14.

[0028] The old oil discharged from the hydraulic station oil tank is collected by the oil receiving tank 14. The old oil is filtered by the filter plate 15. The oil pump 16 is activated to send the old oil filtered by the filter plate 15 back to the oil tank along the oil delivery pipe 18, so as to flush the inner wall of the oil tank and help remove the impurities that have settled inside the oil tank.

[0029] Working principle of this utility model:

[0030] The hydraulic station oil tank is hoisted onto the U-shaped plate 11 using a crane. The U-shaped plate 11 supports the hydraulic station oil tank, and the second hydraulic cylinder 12 is activated to extend, causing the second hydraulic cylinder 12 to push the clamping plate 13 to move. The clamping plate 13, together with the U-shaped plate 11, can firmly clamp the oil tank. The drain valve on the oil tank is opened, allowing the old oil inside the oil tank to be discharged.

[0031] The old oil is collected by the oil receiving tank 14, and the old oil is simply filtered by the filter plate 15, so that the impurities are isolated above the filter plate 15. After the oil tank is drained, the drain valve is closed, and the oil delivery pipe 18 is inserted into the oil tank along the oil tank inlet. The oil pump 16 is started to send a certain amount of filtered old oil back into the oil tank. Then, the first hydraulic cylinder 9 is started to drive the oil tank to swing around the carrier pipe 5. The old oil in the oil tank can flush the inner wall of the oil tank. After the oil tank swings for a period of time, the first hydraulic cylinder 9 is closed, and the drain valve is opened again to drain the old oil in the oil tank, so that the impurities inside the oil tank are discharged with the old oil. The above operation is repeated many times until all the impurities settled at the bottom of the oil tank are discharged with the old oil.

[0032] Pull the oil supply pipe 18 out of the oil tank, and then fill the oil tank with new oil through the oil inlet. After filling a certain amount, the vibration motor 10 can be turned on to run, so that the vibration motor 10, together with multiple shock absorbers 2, drives the oil tank to vibrate, which accelerates the discharge of air bubbles in the new oil. After a period of time, turn off the vibration motor 10 and observe whether the new oil level in the oil tank drops, and decide whether to add new oil. Finally, seal the oil inlet of the oil tank, operate the second hydraulic cylinder 12 to retract, and use the crane to remove the hydraulic station oil tank, thus completing the oil change operation of the hydraulic station oil tank.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
