Description

Technical Field

[0001] The utility model relates to the technical field of dual-mode shield machines, in particular to a dual-mode shield machine cleaning device. Background Art

[0002] The dual-mode shield machine is an improved model that adds an open mode to the shield machine. It has two modes: earth pressure balance (EPB) and open (TBM), which enable rapid interchange within the tunnel. During the excavation process of the shield machine cutterhead, mud adheres to the gap between the tool and the cutterhead, which needs to be cleaned manually regularly.

[0003] Currently, most shield machine cutterhead cleaning methods on the market are done manually. Due to the large size of the shield machine cutterhead, manual cleaning takes a long time and requires constant prying of the soil, which is very laborious. Alternatively, the high-pressure water jet nozzle is driven to rotate and flush the cutterhead. However, this method is inefficient and can only clean partially solidified soil. It is easy for some dead corners to be unable to be cleaned. Therefore, it is necessary to improve a dual-mode shield machine cleaning device to solve the above problems. Utility Model Content

[0030] Embodiment 2:

[0031] See also Figure 5 , and combined with Example 1, it is further obtained that the filtering mechanism 8 includes a collecting frame 81, the collecting frame 81 is arranged on the top of the base 1, and a water pump 82 is fixedly installed on the back of the collecting frame 81, and a return pipe 83 is fixedly installed on the back of the water pump 82. A delivery hose 84 is fixedly installed on the end of the return pipe 83 away from the water pump 82, and a filter frame 85 is slidably installed inside the collecting frame 81. Handles 86 are fixedly installed at the front and back of the filter frame 85, and a baffle 87 is fixedly installed on the outside of the swivel 72 to prevent the delivery hose 84 from contacting the gear ring 712 and causing damage to the delivery hose 84.

[0032] Furthermore, a baffle 87 is provided on the top of the gear ring 712, one end of the delivery hose 84 away from the return pipe 83 is fixedly mounted on the swivel 72, and a handle 86 is slidably mounted inside the collection frame 81. By pulling the two handles 86, the filter frame 85 can be removed to clean the internal dirt.

[0033] In actual operation, when this device is used, the two rotating rods 79 are rotated to make the opening of the cleaning barrel 3 leak out, the double-mode shield machine cutter head is placed on the top of the leak plate 6, the two rotating rods 79 are rotated to reset to be in a straight line, and the positioning bolts 711 are threadedly installed inside the rotating rod 79 and the fixed shaft 78, so that the rotating rod 79 is positioned after rotation, and the fixed shaft 78 and the conveying cavity B and the conveying cavity A in the rotating rod 79 are connected, the external water pipe and the water inlet pipe 76 are installed, the gate A5 is closed, and the gate B77 is opened to allow water to enter the conveying cavity A and the conveying cavity B, and finally sprayed out through the high-pressure nozzle 710, and at the same time the drive motor 74 is started to drive the gear 75 to rotate, the gear ring 712 is engaged with the gear 75, and the rotating ring 72 is driven to rotate, so that the two rotating rods 79 rotate around the center, so that water is rotated and sprayed out through the high-pressure nozzle 710. The cutter head of the dual-mode shield machine is sprayed in all directions, and the large pieces of sludge stuck on the cutter head of the dual-mode shield machine are washed vigorously. The first step of cleaning is carried out until the cutter head of the dual-mode shield machine is completely immersed in water. The vibration motor 9 is started to vibrate the water inside the cleaning barrel 3, and the remaining dirt on the cutter head of the dual-mode shield machine is cleaned in all directions without dead angles. The cutter head of the dual-mode shield machine is further cleaned, and the cleaning effect is better. After cleaning, the gate A5 is opened to allow the sewage to flow into the collection frame 81 through the drain pipe 4. The filter frame 85 filters the sewage, and the filtered water is stored in the collection frame 81. At this time, the gate B77 can be closed to stop using the external water source. The water inside the collection frame 81 enters the return pipe 83 under the action of the water pump 82, and flows back to the inside of the swivel 72 through the delivery hose 84. It can be reused, saving water resources.

[0034] It should be noted that a flow meter 10 is provided on the outside of the return pipe 83 in the device, and a speaker 11 is provided on the outside of the arc plate 2 installed on the left. The flow meter 10 and the speaker 11 are electrically installed and used in conjunction with each other. The flow meter 10 can detect the timed flow in the return pipe 83. When the flow is too small, it means that the filter frame 85 is blocked. At this time, the flow meter 10 controls the speaker 11 to sound an alarm, prompting the operator to clean the filter frame 85. At this time, the collection frame 81 can be pulled to move the filter frame 85 out of the bottom of the drain pipe 4, and the two handles 86 are pulled to move the filter frame 85 out to clean the internal dirt.

[0035] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
