Description

Technical Field

[0001] This utility model relates to an improved invention of a hydraulic power station, and more particularly to an improved invention of a hydraulic hose venting device. Background Technology

[0002] In the existing technology, when a hydraulic pile driver performs pile driving operations, it needs to be connected to an external power station to supply hydraulic oil. However, the power station pumps the hydraulic oil from the hydraulic oil tank to the hydraulic pile driver, which causes hydraulic oil residue to remain in the hydraulic pile driver and the hydraulic oil delivery hose, making it impossible to recover quickly and effectively, resulting in the loss of hydraulic oil in the power station. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a hydraulic hose venting device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the hydraulic hose venting device includes a power station and a hydraulic oil tank. The power station is connected to an external hydraulic drive device through a first hose. The external hydraulic drive device is equipped with an air compressor. The air compressor's inlet end is connected to an air storage tank through a first air pipe. The air compressor's outlet end is connected to the inlet of a pressure control valve through a second air pipe. The pressure control valve outlet is connected to the hydraulic drive device through a second hose.

[0005] The maximum pressure of the pressure control valve is 3 bar.

[0006] The external hydraulic drive device is a hydraulic pile driver.

[0007] The beneficial effect of this utility model is that the improved hydraulic hose venting device, on external hydraulic drive equipment, specifically a hydraulic pile driver, is connected to an external air compressor and equipped with a pressure control valve and an air tank, to deliver high-pressure gas to the external hydraulic equipment, so that all the hydraulic oil in the external hydraulic equipment and the hose is quickly and effectively recovered into the hydraulic oil tank of the power station. Attached Figure Description

[0008] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0009] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0010] The accompanying drawings illustrate the structure of this utility model, and further details will be described below in conjunction with the drawings. In this embodiment, see the attached drawings. Figure 1The hydraulic hose venting device includes a power station 1 and a hydraulic oil tank 2. The power station 1 is connected to an external hydraulic drive device 4 via a first hose 3. The external hydraulic drive device 4 is equipped with an air compressor 5. The air compressor 5 has an air inlet connected to an air storage tank 7 via a first air pipe 6. The air compressor 5 has an outlet connected to the inlet of a pressure control valve 9 via a second air pipe 8. The outlet of the pressure control valve 9 is connected to the external hydraulic drive device 4 via a second hose 10. The second hose 10 and the first hose 3 have different interfaces on the external hydraulic drive device 4 or are connected to the same interface via a T-junction.

[0011] The working principle of this utility model is as follows: the air compressor 5 further pressurizes the compressed gas in the air storage tank 7 through the first air pipe 6, and then delivers it to the pressure control valve 9 through the second air pipe 8. When the gas pressure meets the opening conditions of the pressure control valve 9, the gas enters the second hose 10, the external hydraulic drive device 4, and the first hose 3 in sequence, so that all the hydraulic oil in the second hose 10, the external hydraulic drive device 4, and the first hose 3 is recovered into the hydraulic oil tank 2 of the power station 1.

[0012] As a further improvement, the maximum pressure of the pressure control valve 9 is 3 bar, that is, the pressure of the compressed air transmitted by the air compressor 5 is greater than or equal to 3 bar to open the pressure control valve 9, so that the compressed air meets the requirements of the hydraulic oil return pressure.

[0013] As a further improved specific implementation, the external hydraulic drive device 4 is a hydraulic pile driver, which includes a hydraulic structure for driving the pile hammer to rise and fall. This is an existing structure and will not be described in detail here.

[0014] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
