Description

Technical Field

[0001] The invention relates to the technical field of auxiliary dust prevention equipment, and in particular to auxiliary dust prevention equipment based on radar detection of a shield machine. Background Art

[0002] The shield machine is a large mechanical equipment used for tunnel excavation. It cuts soil or rock in front through a rotating cutterhead and transports the excavated materials out of the tunnel through a conveyor belt or screw conveyor. The outer shell of the shield machine can provide support and protection, and various equipment and systems can also be installed. The shield machine radar detection is a technology used to detect the geological conditions in front of the tunnel. It obtains geological information such as stratum structure, rock type, groundwater, etc. by emitting electromagnetic waves and receiving reflected signals. However, during the tunnel excavation process, a large amount of dust and debris will be generated. These dust and debris will enter the radar detection system, affecting the detection accuracy and reliability. In order to improve the accuracy and reliability of the radar detection system, auxiliary dust prevention measures are required to prevent dust and debris from entering the radar detection system.

[0003] At present, some shield machines have adopted simple dust prevention measures, such as installing filter screens. However, the filter screens will be clogged with dust during the excavation process of the shield machine and need to be frequently cleaned or replaced, which increases maintenance costs and downtime. The filter screens are usually disassembled and cleaned after the shield machine stops running. The shield machine is not easy to clean when it is excavating underground, and there are certain safety risks in cleaning work inside the narrow shield machine. Therefore, the current shield machine cannot be cleaned and filtered at the same time during operation, and dust will gradually accumulate inside the equipment, which will cause the performance of the equipment to decline, such as reducing the detection accuracy of the radar or affecting the normal operation of other key components.

[0004] Therefore, the present invention proposes an auxiliary dust prevention device based on shield machine radar detection to improve the shortcomings of traditional technology. It can realize regular cleaning of the filter screen during the excavation process of the shield machine to prevent the filter screen from being blocked and affecting the accuracy of radar detection. Summary of the invention

The combination of the cross filter soft brush and the hard steel brush can effectively clean the filter. The cross filter soft brush can gently clean the cross filter holes, while the hard steel brush can handle the stubborn dust and dirt accumulated on the cross filter soft brush, ensuring a higher degree of filter cleaning. The dust can be collected through the negative pressure suction tube, which can quickly remove the cleaned dust and dirt, avoiding dust from flying again in the working environment and improving cleaning efficiency. This design can reduce the frequency of manual cleaning and reduce labor costs. Operators can keep the equipment clean with less intervention. This linkage design can complete multiple tasks in one operation, saving time and energy. Different components can work at the same time, reducing the time of individual operations and improving overall work efficiency. The combination of the two ensures comprehensive cleaning of the cross filter holes. BRIEF DESCRIPTION OF THE DRAWINGS

The combination of the two ensures the comprehensive cleaning of the cross filter hole 52.

[0034] The following is the entire working process and working principle of the above embodiment:

[0035] First, a large amount of dust and debris will be generated during the tunnel excavation process of the shield machine. These dust and debris will enter the radar detection body 4 through the air inlet 3. A fixed plate 51 and a cross filter hole 52 are installed inside the air inlet 3. The cross filter hole 52 filters the dust. There will be a lot of dust when the shield machine is digging underground. When the shield machine works for a long time, the filtered dust will accumulate at the cross filter hole 52. The operator turns on the drive device, which drives the first rotating plate 57 to rotate. The first rotating plate 57 rotates one circle, driving the first cylinder 58 to rotate one circle with the center of the first rotating plate 57 as the center. During the rotation of the first rotating plate 57, it slides inside the arc groove plate 56. Since the outer surface of the arc groove plate 56 is provided with four slide grooves, the first rotating plate 57 will slide inside the slide groove of the arc groove plate 56 during the rotation. Since the slide grooves of the arc groove plate 56 are arranged in a circle, the first rotating plate 57 drives the arc groove plate 56 to rotate 90 degrees. The rotation of the arc groove plate 56 drives the main shaft cylinder 55 to rotate. The rotation of the main shaft cylinder 55 drives the cross filter screen soft brush 54 to rotate. During the rotation of the cross filter screen soft brush 54 by 90 degrees, it passes through the cross filter hole 52 and rubs and cleans the cross filter hole 52. The automatic dust prevention The coordinated use of the component 5 can realize automatic cleaning of the cross filter hole 52 during the operation of the shield machine to prevent excessive dust from clogging the cross filter hole 52. The coordinated use of the arc groove plate 56, the first rotating plate 57 and the first cylinder 58 can realize that the first rotating plate 57 rotates one circle to drive the arc groove plate 56 to rotate ninety degrees. The rotation of the arc groove plate 56 causes the cross filter screen soft brush 54 to rotate to clean the cross filter hole 52 once. By regularly controlling the rotation of the first rotating plate 57, regular cleaning can be achieved during the operation of the shield machine to avoid a reduction in the dust prevention effect of the cross filter hole 52. This component is arranged on the fixed plate 51 The cross filter hole 52 is designed to filter dust, and combined with the cross filter soft brush 54, the cleaning process of the cross filter hole 52 is more automated, and the accumulated dust can be removed quickly and effectively. The cross-shaped design can ensure that each part of the cross filter hole 52 can be cleaned evenly, rather than concentrating on a certain area. Through regular and effective cleaning, the damage to the cross filter hole 52 caused by long-term accumulation of dust can be reduced, the service life of the cross filter hole 52 and the fixing plate 51 can be extended, and the replacement frequency can be reduced. This design combines the filtering and cleaning functions together, simplifies the cleaning process, and makes the use of the equipment more convenient.

[0036] In summary, the auxiliary dust prevention equipment based on shield machine radar detection has the advantages of higher cleaning efficiency, reduced manual intervention, extended filter service life, and improved detection accuracy compared to traditional filter cleaning methods by designing a cross filter hole 52 and cooperating with a cleaning mechanism of a rotating cross filter soft brush 54. This design can better adapt to complex working environments and ensure the stability and reliability of the radar detection system.

[0037] At the same time, the rotation of the first rotating plate 57 will drive the second rotating plate 62 to rotate through the transmission of the transmission belt 61, and the rotation of the second rotating plate 62 will drive the second cylinder 63 to rotate with the second rotating plate 62 as the center. When the second cylinder 63 rotates, it will slide inside the vertical circular ring plate 65 and drive the vertical circular ring plate 65 to move. Since the sliding rod 64 is restricted to slide only inside the fixed column 66, the movement of the vertical circular ring plate 65 drives the sliding rod 64 to slide inside the fixed column 66. When the sliding rod 64 moves, it drives the hard steel brush 68 to slide inside the protective cover 67. During the sliding process of the hard steel brush 68, the brush of the cross filter soft brush 54 will be scraped to make dust fall off the cross filter soft brush 54, and then the negative pressure suction tube will be used to suck the dust inside the protective cover 67 and suck the dust into the dust collection box 69. Through the coordinated use of the auxiliary component 6, the cross filter soft brush 54 can clean the cross filter hole 52 while driving the hard steel brush 68 to move and comb the dust on the cross filter soft brush 54 The dust is collected by the negative pressure suction tube to avoid excessive dust accumulation on the cross filter soft brush 54, which may result in ineffective subsequent cleaning of the cross filter hole 52. The combination of the cross filter soft brush 54 and the hard steel brush 68 can effectively clean the filter. The cross filter soft brush 54 can gently clean the cross filter hole 52, while the hard steel brush 68 can handle the stubborn dust and dirt accumulated on the cross filter soft brush 54, ensuring a higher degree of filter cleanliness. Dust is collected by the negative pressure suction tube, which can quickly remove the cleaned dust and dirt to avoid dust flying again in the working environment, thereby improving cleaning efficiency. This design can reduce the frequency of manual cleaning and reduce labor costs. Operators can keep the equipment clean with less intervention. This linkage design can complete multiple tasks in one operation, saving time and energy. Different components can work at the same time, reducing the time of individual operations and improving overall work efficiency. The combination of the two ensures comprehensive cleaning of the cross filter hole 52.

[0038] In summary, this design that combines the cross filter soft brush 54 with the hard steel brush 68 and collects dust through negative pressure can bring significant advantages in improving cleaning efficiency, reducing manual intervention, and improving detection performance and safety. This optimization can not only effectively cope with complex working environments, but also improve the reliability and stability of the entire shield machine radar detection system.
