Description

Technical Field

[0002] Tunnel escape pipes refer to escape passages designed specifically for emergencies that may occur during tunnel construction or operation. These pipes are usually installed inside the tunnel so that in the event of collapse, fire or other emergencies, construction workers or passengers can quickly evacuate to a safe area through the pipes, thereby effectively reducing casualties.

[0053] Example 2 further optimizes the socket-type fixing device for connecting the escape pipe provided in Example 1. Specifically, Figure 1 , Figure 7 and Figure 8 As shown, the docking mechanism 5 includes a sleeve plate 50, which is sleeved on the surface of the horizontal plate 425. One side of the sleeve plate 50 is connected to a second spring telescopic rod 51, one side of the second spring telescopic rod 51 is connected to a first docking ring 52, the surface of the sleeve plate 50 is connected to an electric push rod 53 through a support plate, the left side of the electric push rod 53 is connected to a fixed block 54, and one side of the fixed block 54 is connected to the horizontal plate 425.

[0063] The use process of the socket-and-spigot type fixing device for connecting an escape pipe provided by the present invention is as follows:

[0064] S1. Pushing: The right end of the connecting rope 41 is tied to the first U-shaped rod 42, and the left end of the connecting rope 41 is tied to the threaded rod 40. By controlling the linear motor 413 to run, the two slides 414 are driven to approach each other. The slide 414 drives the moving plate 411, the driving tube 48 and the first spring telescopic rod 49 to move horizontally. The bottom of the first spring telescopic rod 49 squeezes the inner wall of the spiral groove 46, so that the longitudinal tube 45 drives the partition plate 44 and the roller 43 to rotate forward. When the two first spring telescopic rods 49 move away from each other, the inclined surface 410 squeezes the inner wall of the spiral groove 46 to shrink, so that the bottom of the first spring telescopic rod 49 is away from the inner cavity of the spiral groove 46, avoiding the longitudinal tube 45 from rotating in the opposite direction, and the roller 43 continues to rotate forward, winding the connecting rope 41. The connecting rope 41 pulls the escape pipe body 1 to move to the right, without the need for manual handling of the pipe, saving time and effort;

[0065] S2. Dust removal: When the two escape duct bodies 1 are moved together, the connecting rope 41 is separated and disassembled from the threaded rod 40, and the threaded rod 40 is separated and disassembled from the threaded hole 3. The two movable plates 411 are moved closer to each other through operation. The movable plate 411 drives the vertical plate 427 to move through the first spring 416 and the first guide rod 423. The vertical plate 427 drives the horizontal plate 425 to move. The horizontal plate 425 drives the sleeve plate 50, the second spring telescopic rod 51 and the first docking ring 52 to move. The two first docking rings 52 position and support the escape duct body 1. The horizontal plate 425 also drives the driving rod 510 and the second docking ring 513 to move. The dust removal cotton 517 on the inner wall of the two second docking rings 513 contacts the surface of the escape duct body 1 on the left side.
