Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machines, and in particular to a device for controlling the injection of grease into the outer sealing grease of the main drive of a tunnel boring machine. Background Technology

[0002] A tunnel boring machine (TBM) is a type of tunnel boring machine that uses the shield tunneling method. The shield tunneling method involves the tunnel boring machine constructing a "shield" of the tunnel while simultaneously excavating, which differs from open-face construction methods.

[0003] Since tunnel boring machines are usually located tens of meters below the ground, there is a large amount of water and soil pressure at the excavation face. Pressurized water, soil, and silt can easily enter the main drive. During use, a large amount of grease needs to be injected every day to lubricate the moving parts of the main drive. Now, grease is injected into the main drive of the tunnel boring machine through a pumping device.

[0004] However, current pumping devices use hydraulic rods to retract and pull the sealing cap connected to one end of the delivery pipe into the grease tank. Then, a delivery pump is used to extract the grease from the tank for delivery. This means that after the grease in a tank is used up, the tank needs to be manually moved to the base, and its position needs to be constantly adjusted to align with the sealing cap before the hydraulic rod is activated to retract and pull the sealing cap into the tank. This increases the time required to change tanks, reduces work efficiency, and can also lead to situations where the sealing cap is not aligned with the tank.

[0005] Therefore, it is necessary to provide a device for controlling the injection of grease into the external seal of the main drive of a tunnel boring machine to solve the above-mentioned technical problems. Utility Model Content

A limit ring is fixedly connected to the top of each of the two rotating blocks.

[0010] Two movable slots are provided inside the base, and two touch blocks are fixedly connected inside each of the two movable slots. A touch switch is provided on the top of each of the two touch blocks.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a device for controlling the injection of grease into the main drive outer seal of a tunnel boring machine provided by this utility model; Figure 2 for Figure 1 A cross-sectional structural schematic diagram of the base shown; Figure 3 for Figure 1 The enlarged schematic diagram of part A shown below;

[0029] Figure 4 for Figure 2 The enlarged schematic diagram of section B shown. A device for controlling the injection of grease into the main drive outer seal of a tunnel boring machine, comprising:

[0030] Base 1, with a discharge part 7 provided on the top of the base 1;

[0031] Two rotating slots 2 are provided inside the base 1. A rotating block 21 is slidably connected inside each of the two rotating slots 2. A rotating hole 22 is provided inside each of the two rotating blocks 21. A rotating rod 23 is threadedly connected inside each of the two rotating holes 22. A rotating motor 24 is provided at one end of each of the two rotating rods 23. A limit ring 3 is fixedly connected to the top of each of the two rotating blocks 21.

[0032] Two movable slots 4 are located inside the base 1. Two touch blocks 5 are fixedly connected inside each of the two movable slots 4. A touch switch 6 is provided on the top of each of the two touch blocks 5.

[0033] The discharge unit 7 includes two hydraulic rods, a moving frame, a conveying pipe, a sealing cover, and a conveying pump. The two ends of the two hydraulic rods are fixedly installed on the moving frame and the base 1, respectively. The conveying pipe is fixedly installed inside the moving frame and one end is fixedly installed on the input end of the conveying pump. The conveying pump is fixedly installed on the top of the moving frame and the output end is also fixedly installed with the conveying pipe. It is used to move the conveying pump and the conveying pipe downward and to convey the grease.

[0034] Both rotating slots 2 are rectangular slots. The rotating block 21 is a rectangular block that is adapted to the rotating slot 2. The top of the block has two fixedly connected limit rings 3. The bottom of the two rotating blocks 21 is fixedly connected to a touch switch 6. When the rotating block 21 moves to one side, the rotating motor 24 will automatically turn off after the touch switch 6 contacts the touch block 5.

[0035] The rotating rod 23 is a threaded rod, and the rotating hole 22 is a threaded hole adapted to the rotating rod 23. It is used to move the rotating block 21 to one side on the surface of the rotating rod 23 when the rotating rod 23 rotates to one side.

[0036] Both of the rotating motors 24 are fixedly installed on one side of the base 1, and their output ends are respectively connected to one end of the two rotating rods 23 via couplings.

[0037] The rotating block 21 has two sliding holes 8 inside, and a sliding rod 9 is slidably connected inside each of the two sliding holes 8.

[0038] The two ends of the two sliding rods 9 are fixedly connected to the two sides of the inner wall of the rotating groove 2. When the rotating block 21 moves to one side, it drives the sliding holes 8 to move to one side on the surface of the sliding rods 9, thereby increasing the stability of the rotating block 21 when it moves.

[0039] The working principle of the device for controlling the injection of grease into the main drive outer seal of a tunnel boring machine provided by this utility model is as follows:

[0040] In use, the oil drum is placed inside the limiting ring 3 at the top of the rotating block 21.

[0041] After the grease in the previous oil drum has been transported, the rotating motor 24 is started, which drives the rotating rod 23 to rotate to one side. This causes the rotating block 21 to move to one side on the surface of the rotating rod 23. When the rotating block 21 moves to one side, it drives the touch switch 6 to move to one side and contact the touch block 5. Then the rotating motor 24 is turned off, the empty oil drum is moved out from under the discharge part 7, and the new oil drum moves to the bottom of the discharge part 7, thus automatically changing the oil drum.

[0042] Compared with related technologies, the device for controlling the injection of grease into the main drive outer seal of a tunnel boring machine provided by this utility model has the following advantages:

[0043] This utility model provides a device for controlling the injection of sealing grease into the main drive of a tunnel boring machine. After the oil drum is placed inside the limiting ring 3 at the top of the rotating block 21, the rotating motor 24, in conjunction with the rotating rod 23 and the rotating hole 22, causes the rotating block 21 to automatically move to one side and below the discharge component 7. After the touch switch 6 contacts the touch block 5, the rotating motor 24 automatically shuts off, thus facilitating the placement and transportation of the oil drum to a suitable position. The oil drum automatically aligns with the discharge component 7, eliminating the need for manual handling and adjustment, reducing loading time, and increasing work efficiency.

[0044] Second Embodiment

[0045] Please refer to the following: Figure 5 and Figure 6 Based on the device for controlling the injection of grease into the main drive outer seal of a tunnel boring machine provided in the first embodiment of this application, the second embodiment of this application proposes another device for controlling the injection of grease into the main drive outer seal of a tunnel boring machine. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0046] Specifically, the second embodiment of this application provides a device for controlling the injection of grease into the main drive outer seal of a tunnel boring machine. The device for controlling the injection of grease into the main drive outer seal of a tunnel boring machine has two sliding grooves 10 inside the base 1, and sliding blocks 11 are slidably connected inside the two sliding grooves 10.

[0047] Both sliding grooves 10 are formed inside the base 1 and are located on both sides respectively.

[0048] The tops of the two sliding blocks 11 are rotatably connected to telescopic members 12, and the tops of the two telescopic members 12 are fixedly connected to fixing rings 13.

[0049] When the telescopic component 12 is moved to one side, it drives the sliding block 11 to move to one side inside the sliding groove 10, thereby feeding the inside of the limiting ring 3.

[0050] Two fixing members 14 are fixedly installed inside each of the two fixing rings 13, and a fixing clip 15 is fixedly installed at one end of each of the fixing members 14.

[0051] Both the fixing member 14 and the telescopic member 12 can be electric push rods or hydraulic rods, used to drive the fixing clamp 15 and the fixing ring 13 to move respectively.

[0052] Each of the plurality of fixing clips 15 is fixedly connected to a protective pad 16 on one side, the protective pad 16 being made of rubber.

[0053] The protective pad 16 is used to increase the friction between the fixing clip 15 and the oil drum, thereby increasing the fixing effect of the fixing clip 15.

[0054] The working principle of the device for controlling the injection of grease into the main drive outer seal of a tunnel boring machine provided by this utility model is as follows:

[0055] In use, after rotating the fixing ring 13 to a suitable position, the telescopic component 12 is activated to descend and cover the oil drum. Then, the two fixing components 14 are activated to extend to one side, thereby causing the two fixing clamps 15 to extend to a suitable position and clamp the oil drum. After clamping the oil drum, the telescopic component 12 is activated again to extend upward to a suitable position and rotate to one side to a suitable position. Then, the telescopic component 12 is activated again to retract, allowing the oil drum to enter the interior of the limiting ring 3. Finally, the two fixing components 14 are activated to release the clamps 15 from the oil drum.

[0056] Compared with related technologies, the device for controlling the injection of grease into the main drive outer seal of a tunnel boring machine provided by this utility model has the following advantages:

[0057] This utility model provides a device for controlling the injection of sealing grease into the main drive of a tunnel boring machine. Two fixing members 14 extend to one side, driving two fixing clamps 15 to move to one side and clamp the oil drum. The telescopic member 12 extends, retracts, and rotates to place the oil drum inside the limiting ring 3, thus facilitating the placement of the oil drum inside the limiting ring 3.

[0058] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
