Description

Cutterhead cleaning mechanism and tunnel boring mechanism

Technical Field

The utility model relates to the technical field of tunnel excavation, in particular to a cutter head cleaning mechanism and a tunnel excavation mechanism.

Background Art

A tunnel boring machine is a comprehensive equipment that uses mechanical crushing of rocks, mucking and support to carry out continuous operations. According to the cutting process of the tunnel boring machine on the working face, it is divided into full-section tunnel boring machines and partial-section tunnel boring machines. According to the different principles of rock crushing, it can be divided into roller-type (disc cutter) tunnel boring machines and milling-cutting tunnel boring machines.

A Chinese patent discloses a tunnel boring machine (authorization announcement number CN208330375U). The patented technology has a thrust cylinder connected to the tunnel boring machine body, and a support shoe device supports a support ring to withstand the reverse thrust of the thrust cylinder. During the tunnel construction process with general or good geological conditions, the tunnel wall still has good safety and stability when the tunnel wall is not assembled with pipe segments for lining. The support shoe device is directly supported on the tunnel wall on both sides of the tunnel, relying on the friction between the support shoe device and the surrounding rock of the tunnel wall to withstand the reverse thrust and torque of the thrust cylinder transmitted by the support ring. However, the existing tunnel boring mechanisms on the market may not be convenient for cleaning the blade after the work is completed, and the staff may need to clean it manually. The cleaning efficiency and cleanliness rate may not be high enough, which may lead to reduced work efficiency when used next time.

Therefore, those skilled in the art provide a cutterhead cleaning mechanism and a tunnel boring mechanism to solve the problems raised in the above background technology.

After the adjustment is completed, the first pull plate 16 is pushed in to drive the first plug rod 14 to be inserted, so that the rotating disk 10 is limited, thereby achieving the adjustment of the water outlet 11.

Below we will discuss in detail the specific settings and functions of the main innovation name and auxiliary innovation name.

3 and 4, the surface of the first plug rod 14 is slidably connected with the first spring 15, and the bottom end of the first spring 15 is fixedly connected to the top end of the first connecting plate 13. When the angle of the water spout 11 needs to be adjusted again during work, the first pull plate 16 is gently pulled out, and the first spring 15 begins to release its elastic force, driving the first plug rod 14 to be quickly pulled out, so that the rotating disk 10 is released from the limit, thereby achieving quick adjustment of the water spout 11. The surface of the rotating disk 10 is provided with a first opening 12, and the inner diameter of the first opening 12 is adapted to the outer diameter of the first plug rod 14. When the staff fixes the water spout 11 When the air pump moves the water outlet 11 to the front and rear positions, the surface of the bottom end of the slider 18 is fixedly connected to the surface of the top end of the adjusting block 6. When the air pump moves the water outlet 11 to the front and rear positions, the surface of the bottom end of the slider 18 is fixedly connected to the surface of the top end of the adjusting block 6. Therefore, the slide groove and the slider form a stable limit when moving, thereby achieving stable movement of the water outlet.

5 and 6, a second connecting plate 19 is fixedly connected to the surface of the extending frame 3, a second plug rod 20 is slidably connected to the surface of the second connecting plate 19, a second pull plate 22 is fixedly connected to the surface of the front end of the second plug rod 20, and a second opening 23 is provided on the surface of the supporting frame 2. When the staff needs to deal with tunnel boring mechanism bodies 8 of different sizes, the second pull plate 22 is pulled out to drive the second plug rod 20 to be pulled out, so that the supporting frame 2 and the extending frame 3 are released from the limit. After the adjustment is completed, the second pull plate 22 is pushed in to drive the second plug rod 20 to penetrate the second opening 23, so as to achieve the height adjustment of the limiting frame 5. The surface of the second plug rod 20 is slidably connected to the second spring 21, and the bottom of the second spring 21 The end is fixedly connected to the top end of the second connecting plate 19. When the angle of the limit frame 5 needs to be adjusted again, the second pull plate 22 is gently pulled out, and the second spring 21 begins to release the elastic force, driving the second plug rod 20 to be quickly pulled out, so that the extension frame 3 is released from the limit, thereby achieving quick adjustment of the limit frame 5. The surface inside the extension frame 3 is fixedly connected with a buffer spring 24. The inner diameter of the buffer spring 24 is matched with the outer diameter of the support frame 2. When the staff adjusts the height of the limit frame 5, the extension frame 3 may accidentally slip down. At this time, the buffer spring 24 accumulates force. When the lower pressure disappears, the buffer spring 24 releases the elastic force, so that the extension frame 3 is buffered, thereby achieving buffering when the extension frame 3 accidentally slips down.

Working principle: when the staff needs to adjust the up and down angle of the water spout 11, the first pull plate 16 is pulled out to drive the first plug rod 14 to be pulled out, so that the rotating disk 10 is released from the limit, and the water spout 11 is adjusted up and down. After the adjustment is completed, the first pull plate 16 is pushed in to drive the first plug rod 14 to be inserted, so that the rotating disk 10 is limited, thereby achieving the adjustment of the water spout. When the angle of the water spout 11 needs to be adjusted again, the first pull plate 16 is gently pulled out, and the first spring 1 5 begins to release the elastic force, driving the first plug rod 14 to be quickly pulled out, so that the rotating disk 10 is released from the limit, thereby achieving quick adjustment of the water spout 11. When the staff fixes the water spout 11, the first pull plate 16 is pushed in to drive the first plug rod 14 to penetrate the first opening 12 on the rotating disk 10, so that the water spout 11 reaches a stable limit, thereby achieving a stable limit of the water spout 11. When the air pump moves the front and rear positions of the water spout 11, the surface of the bottom end of the slider 18 is in contact with the top of the adjusting block 6. The surface of is fixedly connected, so the slide groove and the slider form a stable limit when moving, thereby achieving stable movement of the water nozzle. When the staff needs to deal with tunnel excavation mechanism bodies 8 of different sizes, the second pull plate 22 is pulled out, driving the second plug rod 20 to be pulled out, so that the support frame 2 and the extension frame 3 are released from the limit. After the adjustment is completed, the second pull plate 22 is pushed in to drive the second plug rod 20 to penetrate into the second opening 23, thereby achieving the height adjustment of the limit frame 5. When the work needs to adjust the angle of the limit frame 5 again, the second pull plate 22 is gently pulled out, and the second spring 21 begins to release the elastic force, driving the second plug rod 20 to be quickly pulled out, so that the extension frame 3 is released from the limit, thereby achieving quick adjustment of the limit frame 5. When the staff adjusts the height of the limit frame 5, the extension frame 3 may accidentally slip off. At this time, the buffer spring 24 accumulates force. When the lower pressure disappears, the buffer spring 24 releases the elastic force, so that the extension frame 3 is buffered, thereby achieving buffering when the extension frame 3 accidentally slips off.
