Description

Technical Field

[0001] The utility model relates to the technical field of dust removal in extra-long tunnel construction, and specifically relates to a smoke exhaust and dust removal device for extra-long tunnel construction. Background Technique

[0002] A tunnel refers to an engineering structure buried in the stratum, which is a form of human utilization of underground space. For railways, a tunnel with a total length of more than 10,000 meters is an extra-long tunnel, and for highways, a tunnel with a total length of more than 3,000 meters is an extra-long tunnel; when constructing an extra-long tunnel, due to the long length of the extra-long tunnel, smoke and dust cannot be quickly discharged from the tunnel entrance, so it is necessary to use a smoke exhaust and dust removal device for dust removal operations to provide a construction environment.

[0003] In the patent document with the publication number of CN216691141U that has been published, a smoke exhaust and dust removal device for extra-long tunnel construction in mountainous and plateau areas is disclosed. In this published patent document, a fan is used for ventilation and exhaust, a water pump pumps water from a water tank into a spray head for spraying, and the spraying is more comprehensive for dust reduction. A dust collector sucks dust into a treatment box through an air duct for collection, and the dust attached to the air duct is greatly reduced through dust reduction. By turning a bolt, the L-shaped block is separated from the fixation, and by holding the U-shaped handle and moving it, the U-shaped handle drives the treatment box to be separated from the fixed box, and at this time, it is convenient to collect dust for cleaning; however, in the above published patent document, during the process of smoke exhaust and dust removal in an extra-long tunnel, since the dust removal device cannot move along the extra-long tunnel, manual control of the moving direction is required, resulting in a large working intensity, and the dust removal device of the above patent needs to move on the ground, which will also affect the normal construction of the extra-long tunnel. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a smoke exhaust and dust removal device for extra-long tunnel construction, which solves the problems raised in the background technique.

[0027] In this technical solution, by arranging the dust removal box 1 above the inside of the long tunnel 2, it does not affect the construction inside the long tunnel 2. And by driving one roller 7 to rotate through the servo motor 8, since the grinding sleeve 9 contacts the I-shaped long guide rail 3, the dust removal box 1 can be driven to move along the I-shaped long guide rail 3, so that the dust removal box 1 can move along the long tunnel 2 without manual labor, thus reducing the labor intensity required for smoke exhaust and dust removal in the long tunnel 2.

[0028] In some technical solutions, such as Figure 2-3 As shown, on the lower parts of both sides of the dust removal box 1, air inlet pipes 10 penetrate and are in interference fit connection. On the upper parts of both sides of the dust removal box 1, a number of exhaust holes 12 are opened. The air inlet pipes 10 are communicated with the dust suction chambers 21, and a blower 11 is fixedly installed inside the air inlet pipes 10. Inside the dust suction chambers 21, a matching filter screen 22 is fixedly installed. At the bottom of the water chamber 20, a number of drain pipes 13 are communicated. The lower ends of the drain pipes 13 are communicated with spray nozzles 14, and a solenoid valve 15 is arranged on the drain pipes 13.

[0029] During use, the blower 11 conveys the smoke and air to the dust suction chambers 21 through the air inlet pipes 10. The filter screen 22 blocks the smoke, and the air is discharged through the exhaust holes 12, realizing the function of wind-powered smoke exhaust and dust removal. By opening the solenoid valve 15, the water in the water chamber 20 can be sprayed out through the drain pipes 13 and the spray nozzles 14, realizing the function of water spraying for smoke exhaust and dust removal. It has two smoke exhaust and dust removal methods at the same time, and the smoke exhaust and dust removal effect is good.

[0037] During use, the servo motor 8, the fan 11, and the solenoid valve 15 can be remotely controlled to work through the wireless controller 18.

[0038] Working principle: During the use process, a roller 7 is driven to rotate by the servo motor 8. Since the abrasive sleeve 9 is in contact with the I-shaped long guide rail 3, the dust removal box 1 can be driven to move along the I-shaped long guide rail 3, so that the dust removal box 1 can move along the extra-long tunnel 2 without manual labor, thereby reducing the labor intensity required for smoke exhaust and dust removal in the extra-long tunnel 2. Moreover, the dust removal box 1 is always above the inside of the extra-long tunnel 2, without affecting the construction in the extra-long tunnel 2. The smoke and air are transported to the dust suction chamber 21 through the air inlet pipe 10 by the fan 11.
