Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, and in particular to a cleaning device for the cutterhead of a tunneling machine and the tunneling machine itself. Background Technology

[0002] During the construction of full-face tunnel boring machines, the cutting tools suffer from high wear and frequent replacement. The time spent on cutting tool inspection and replacement accounts for more than 10% of the tunnel construction cycle. If failed cutting tools are not detected and replaced in time, it will cause wear on the cutterhead body, and the project will face the risk of work stoppage for maintenance, which will seriously restrict the project schedule.

[0003] The cutterhead of a tunnel boring machine (TBM) is a vertical, planar mechanical structure operating in a confined, high-pressure, humid, and dark environment with a complex surface structure. When mud cake forms on the cutterhead, it hinders muck removal, leading to a significant increase in shield torque and thrust, a decrease in advance speed, abnormal temperature and wear of the cutterhead tools, and seriously affecting the safety of TBM tunneling. Currently, cutterhead tool inspection mainly involves manual labor after the liquid level in the excavation chamber has dropped to a suitable level. Personnel wearing headlamps climb into the excavation chamber, first using shovels or pneumatic blowers to remove the mud cake, then washing the cutterhead with high-pressure water, and finally inspecting and recording the wear of each tool. This method is labor-intensive, inefficient, and dangerous, and it lacks real-time monitoring, early warning, and proper handling of abnormalities such as mud cake formation.

(Reference) Figure 1 In some embodiments, the tunneling machine includes a cutterhead 100, a housing 600, and a main system 500. The cutterhead 100 is located at the end of the housing 600, and a partition 300 is provided on the inner side of the cutterhead 100. The partition 300 is located inside the housing 600 and forms a soil chamber 200 between itself and the cutterhead 100. The main system 500 is located inside the housing 600 and is located on the side of the partition 300 away from the soil chamber 200.

[0056] During operation, the cutterhead 100 may experience mud cake formation, leading to difficulties in muck removal. This, in turn, causes a significant increase in the tunneling machine's torque and thrust, a decrease in propulsion speed, abnormal temperature and wear of the cutterhead tools, severely impacting the tunneling operation. Some related technologies involve manual cleaning of the cutterhead 100, but this method is inefficient and poses safety hazards to operators.

[0057] Based on this, embodiments of the present invention provide a cleaning device for the cutterhead of a tunneling machine to alleviate the problem of low cleaning efficiency of the cutterhead of a tunneling machine.

The gate 3 can form a sealed space inside the chamber 2 to withstand a certain pressure; when the gate 3 is opened, the chamber 2 is connected to the soil chamber 200.

[0065] In the above embodiment, during the operation of the tunneling machine, the gate 3 is closed, and the monitoring device 4 monitors the soil chamber 200 and the cutterhead 100 of the tunneling machine in real time through the first observation window 31. It also assesses the wear of the cutters on the cutterhead 100 and the presence of mud cake on the cutterhead. Based on the monitoring results of the monitoring device 4, it determines whether the cutterhead 100 needs to be cleaned. When cleaning of the cutterhead 100 is required, the tunneling machine stops operating, the gate 3 opens, and the cleaning device 5 enters the soil chamber 200 to clean the mud cake and other deposits on the cutterhead 100.

[0119] When the tunneling machine is in tunneling mode, gate 3 is closed, and the chamber 2 is a sealed space, separated from the soil chamber 200. The second flushing port 12 cleans the first observation window 31 of gate 3 using high-pressure water or high-pressure air as needed. The monitoring equipment 4 inside the chamber 2 can capture images and use infrared cameras in real time through the first observation window 31 to observe the status of the soil chamber 200 and cutterhead 100, monitor the soil temperature inside the soil chamber 200 and cutterhead 100, and assess cutter wear and cutterhead cake formation. The first flushing port 11 cleans the passage 13 as needed to prevent sludge from solidifying inside the passage 13 and affecting the entry and exit of the cleaning component 53. When soil improvement is required, an amendment can be injected into the soil chamber 200 through the first flushing port 11 to achieve soil improvement.

[0120] When the cleaning component 53 is needed to further inspect and remove mud cake from the cutterhead 100, the tunneling machine stops tunneling, and the first flushing port 11 flushes the connector 1 and the area around the gate 3 with high-pressure water or air. The liquid level in the soil chamber 200 is lowered to below the gate 3 level by the muck removal system, and the pressure is stabilized by pressurizing the soil chamber 200. The pressure is then increased in the chamber 2 by the pressurization system, and the gate 3 is opened when the pressure in the chamber 2 matches the pressure in the soil chamber 200. The cleaning component 53 can be adjusted in position via the rotation assembly 51 and the pitch assembly 52, flushing the gate 3 and connector 1 within the chamber 2, while simultaneously extending out of the chamber 2 into the soil chamber 200 under the drive of the drive component 64.

[0121] The cleaning component 53 adjusts its position via the rotation assembly 51 and the pitch assembly 52. ​​Combined with the rotation of the cutter head 100, this allows the monitoring equipment 4 to observe the entire cutter head 100. The image acquisition element 41 and the infrared camera element 42 detect the cutters on the cutter head 100 and report the location of cutters exhibiting abnormal conditions. The cleaning component 53 can adjust to any angle through the combined action of the rotation assembly 51 and the pitch assembly 52, ensuring no blind spots in the detection. When mud cake, slag, or other debris adheres to the surface of the cutter head cutters and needs to be removed, it can be high-pressure cleaned using the first nozzle 531. During this process, the cleaning effect is monitored in real-time by the monitoring equipment 4. The second nozzle 532 opens as needed to clean the monitoring equipment 4, preventing splashed slag or mud cake from adhering to the surface of the monitoring equipment 4 and affecting observation and detection operations.

[0122] When the structural components of the cleaning equipment 5 are reduced in size, making the radial movement space of the cleaning equipment 5 smaller than the cross-sectional dimensions of the cabin 2, if the cleaning equipment 5 malfunctions, it can be pulled directly back into the cabin 2 by the drive component 64. There is no problem of the cleaning equipment 5 being unable to be withdrawn into the cabin 2 due to interference between the cleaning equipment 5 and the cabin 2. This reduces the maintenance risk after the cleaning equipment 5 malfunctions, and also reduces the operational difficulty for the operator of the cleaning equipment 5.

[0123] After monitoring device 4 completes the inspection of the cutterhead and cutting tools, and cleaning component 53 completes the mud cake cleaning operation, the rotary assembly 51 and pitch assembly 52 adjust cleaning component 53 to return to its initial state, and drive component 64 drives slide 62 and cleaning device 5 to return to the soil chamber 200. Then, the third flushing port 21 on the chamber 2 can be opened to flush the chamber 2, connecting component 1, and gate 3, and then the gate 3 can be closed. After the gate 3 is closed, the state of the slag inside the chamber 2 is observed through camera 8, and the nozzles on the flushing and cleaning equipment 5 can be controlled to flush the slag remaining in the chamber 2. Slag and other impurities can be discharged through the drain port 22 located at the bottom of the chamber 2.

[0124] The entire operation of the cleaning equipment 5 can be monitored in real time by the monitoring equipment 4 on the cleaning component 53 and the camera 8 installed in the cabin 2.

[0125] Some embodiments of the present invention also provide a tunneling machine, which includes a cutterhead 100, a soil chamber 200, and the aforementioned tunneling machine cutterhead cleaning device.

[0126] The tunneling machine also includes a housing 600. The cutterhead 100 is located at the end of the housing 600, and the partition 300 is located inside the housing 600 and is located on the inner side of the cutterhead 100. A soil chamber 200 is formed between the partition 300 and the cutterhead 100.

[0127] Tunneling machines include tunnel boring machines (TBMs).

[0128] The tunneling machine provided in this embodiment of the invention can perform real-time detection of the cutterhead and cutting tools without opening the cabin 2, enabling real-time monitoring, early warning, and timely handling of mud cake.

[0129] Based on the various embodiments of the present invention described above, in the absence of explicit denial or conflict, the technical features of one embodiment may be advantageously combined with one or more other embodiments.

Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of the invention.
