Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machines, specifically to a hydraulic station oil tank for tunnel boring machines. Background Technology

[0002] A tunnel boring machine (TBM), also known as a shield tunneling machine, is a type of tunnel boring machine that uses the shield tunneling method. TBMs are widely used in the construction of tunnels for subways, railways, highways, and water conservancy projects. They offer advantages such as high construction efficiency, effective control of ground subsidence, and minimal disruption to surface traffic and the environment, making them essential equipment for modern urban construction and infrastructure development. The hydraulic station oil tank of the TBM is the "power storage and protection center" of the hydraulic system. Its core functions are to store hydraulic oil, maintain stable system pressure, and provide protection for hydraulic components, directly affecting the reliability of critical actions such as TBM propulsion and cutterhead drive.

[0003] However, existing shield tunneling machine hydraulic station reservoirs require the high-temperature hydraulic oil to be circulated back into the tank during the circulation process. The hydraulic oil that re-enters the reservoir needs to be filtered, and the used hydraulic oil needs to be cooled before it can be recycled. However, natural heat dissipation is not an effective way to cool the hydraulic oil, and the filter screen after filtering is not easy to clean. Utility Model Content

[0013] Beneficial effects This utility model provides a hydraulic station oil tank for a tunnel boring machine, which has the following advantages: 1. The system is equipped with an oil storage tank for storing hydraulic oil, a cooling tank for cooling high-temperature hydraulic oil, a filter plate for filtering the oil, a cleaning component for cleaning the filter plate, a first oil extraction pipe with an oil pump to pump the oil from the storage tank to the cooling oil tank for cooling, and a second oil extraction pipe with an oil pump.

By installing a cooling oil tank, high-temperature oil can be introduced into the cooling oil tank for cooling. By setting up a baffle, rotating the cooling oil tank causes the oil to tumble and flow inside the cooling oil tank during rotation, which can achieve a better heat dissipation effect. By setting up heat dissipation fins, the heat dissipation effect can be further improved. By setting up a fan, the cooling oil tank can be cooled. By setting up heat dissipation holes, heat can be dissipated. 3. A high-pressure blower is installed. When the high-pressure blower is started, high-pressure gas is generated.

The filter plate 18 is installed to clean the cleaning component. The first oil extraction pipe 15 is installed, and the oil pump 16 is installed on the first oil extraction pipe 15 to pump the oil in the oil storage tank 2 to the cooling oil tank 4 for cooling. The second oil extraction pipe is installed, and the oil pump 16 is installed on the second oil extraction pipe. When the oil pump 16 on the first oil extraction pipe 15 is turned off and the oil pump 16 on the second oil extraction pipe is turned on, the cooled oil in the cooling oil tank 4 can be pumped into the filter box 17 for filtration, so that the oil can be recycled after cooling and cleaning.

[0020] By installing a cooling oil tank 4, high-temperature oil can be introduced into the cooling oil tank 4 for cooling. By setting a baffle 5, the cooling oil tank 4 is rotated, and the oil is made to tumble and flow in the cooling oil tank 4 during the rotation, which can achieve a better heat dissipation effect.

[0026] By installing a high-pressure blower 19, high-pressure gas can be generated when the high-pressure blower 19 is started. The high-pressure gas can enter the outlet pipe 20 through the outlet pipe 20. The high-pressure nozzle 25 can spray the gas in the outlet pipe 20 out through the high-pressure nozzle 25, thereby backflushing the filter plate 18 and blowing out the impurities blocked in the holes of the filter plate 18.

[0027] Furthermore, a toothed plate 23 is movably installed above the filter plate 18, and a second gear 22 that meshes with the toothed plate 23 is rotatably installed on the outer wall of the housing 1.

The box door is provided with a counterweight. After the material is discharged, the box door moves in the opposite direction with the scraper 24 and can be automatically closed by the counterweight.

[0033] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0034] The working principle and usage process of this utility model are as follows: In use, open the oil pump 16 on the first oil extraction pipe 15 and the valve on the first oil extraction pipe 15 to pump the high-temperature oil from the oil storage tank 2 into the cooling oil tank 4. Start the motor 9, which drives the first gear 10 to rotate. The first gear 10 meshes with the gear ring 11, driving the gear ring 11 to rotate, thereby rotating the cooling oil tank 4. During rotation, turn on the fan 7 to further cool the cooling oil tank 4. A temperature sensor is installed on the cooling oil tank 4. After the temperature cools to a suitable level, open the valve on the first oil extraction pipe 15 and turn on the oil pump 16 on the second oil extraction pipe, keeping the oil pump 16 on the first oil extraction pipe 15 closed. The cooling oil tank can then be cooled. After the internal cooling is completed, the oil is drawn into the filter box 17 and filtered through the filter plate 18. The filtered oil then enters the oil storage tank 2 through the return oil pipe 13, thus circulating the oil for reuse. After filtration, the high-pressure blower 19 is turned on, and the generated gas is sprayed out through the high-pressure nozzle 25 to back-blow and clean the filter plate 18, causing the impurities blocked in the holes of the filter plate 18 to fall onto the filter plate 18. The second gear 22 is started to rotate, and the second gear 22 meshes with the toothed plate 23 to drive the toothed plate 23 to move, which in turn drives the scraper 24 to move towards the box door, thereby opening the box door and allowing the impurities on the filter plate 18 to be pushed into the impurity collection box 21 for storage.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
