Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction ventilation, and in particular to a road construction tunnel construction ventilation device. Background Art

[0002] The structure of a tunnel consists of two parts: a main building and auxiliary equipment. The main building consists of a tunnel body and a tunnel door. The auxiliary equipment includes a car shelter, fire-fighting facilities, emergency communications and drainage facilities. Long tunnels also have special ventilation and lighting equipment. A Chinese patent discloses a ventilation device for tunnel construction (authorization announcement number CN216142981U). The patent technology discloses a ventilation device for tunnel construction, which relates to the technical field of tunnel construction. The ventilation device for tunnel construction includes a ventilation fan housing, a support frame is arranged inside the ventilation fan housing, the support frame is fixedly connected to the ventilation fan, the lower end of the ventilation fan housing is fixedly connected to a mounting base plate, a dust filter screen is arranged inside the mounting base plate, and a drive motor is fixedly connected to the lower edge of the mounting base plate. The ventilation device for tunnel construction is provided with a driving motor and a driving threaded rod, so that the driving motor drives the threaded rod to rotate and drives the threaded support frame to move forward and then drives the threaded connection frame to move forward, so that the cleaning brush follows the threaded support frame to move forward to clean the surface of the dust filter screen, thereby automatically cleaning the mesh of the dust filter screen every day, saving time and effort, making the oxygen in the tunnel more sufficient, and ensuring the life safety of the construction personnel in the tunnel. This patented technology solves the problem that in the process of tunnel construction, since the tunnel needs to be excavated from the inside to the outside, ventilation facilities need to be well prepared in the tunnel. Most of the existing ventilation facilities realize the air exchange between the inside and outside of the tunnel by installing ventilation fans. During the process of tunnel construction, due to the large amount of dust in the tunnel, the inner dust filter of the ventilation fan needs to be cleaned in time to prevent manual cleaning of the inner dust filter, which is time-consuming and labor-intensive, and easily causes the lack of oxygen in the tunnel due to the untimely exchange of internal and external air, which causes safety hazards to tunnel construction.

[0003] However, in the prior art, since the space in the tunnel is closed and the air is not circulating at night, personnel are required to move the ventilation device to the inside of the tunnel during re-construction, which can easily cause hypoxia or inhalation of harmful gases to the personnel. It is necessary to solve the problem of automatically moving the ventilation device to the inside of the tunnel in the prior art.

The support adjustment plate 304 is rotatably installed on the positioning outer rail frame 301 through the cross locking bolt 306.

[0030] For example 3, please refer to Figures 9-10 In the present embodiment, a mobile ventilation structure 4 in a road construction tunnel construction ventilation equipment is provided, wherein the mobile ventilation structure 4 comprises a ventilation frame 401 sealed and docked with the telescopic air duct 113, a support frame 402 is integrally fixed to the bottom end of the ventilation frame 401, a mobile frame 403 is fixed to the bottom of the support frame 402, and an adjustment plate 404 is rotatably mounted on the bottom of the mobile frame 403, an adjustment shaft 405 is integrally fixed to the top of the adjustment plate 404, the adjustment shaft 405 rotatably penetrates the inner side of the mobile frame 403, and a worm gear 406 is fixedly mounted on the outer wall of the adjustment shaft 405, the worm gear 406 is meshed with a worm 407, and one end of the worm 407 is connected to a servo motor 408.

[0031] A steering wheel 409 is rotatably installed on the outer side of the adjustment plate 404 for driving the mobile ventilation structure 4 on the ground inside the tunnel. Two driving wheels 410 are rotatably installed on the outer wall of the rear side of the mobile frame 403. A driving motor 411 is connected to the center of the driving wheel 410, and the driving motor 411 is installed inside the bottom of the mobile frame 403.

[0032] A detection bracket 412 is fixedly mounted on the bottom wall of the ventilation frame 401 , a gas detector 413 for detecting gas in the tunnel is mounted inside the detection bracket 412 , and a wind speed monitor 414 for detecting ventilation wind speed is mounted on the gas detector 413 .

[0033] According to the above embodiments, the working principle of the present invention is: The construction ventilation structure 1 can autonomously move to the inside of the tunnel through the mobile ventilation structure 4, and detect and process the gas inside the tunnel with the help of the gas detector 413. Once harmful gas is found inside the tunnel, the system will automatically adjust the exhaust direction of the ventilation fan device 102, first extract the air in the tunnel, and then process it through the external air purification device.

[0034] When adjusting the exhaust direction of the ventilation fan device 102, the servo motor 105 is started to drive the worm 104 to rotate, and then engage with the worm wheel 103, so that it drives the ventilation fan device 102 to flip horizontally inside the wind tube frame 101 to adapt to the two ventilation modes of air supply and exhaust.

[0035] When the mobile ventilation structure 4 enters the tunnel, the servo motor 408 is started to drive the worm 407 to rotate, mesh with the worm gear 406, and drive the adjustment plate 404 connected to the bottom of the adjustment shaft 405 to rotate, thereby adjusting the movement angle of the steering wheel 409. Subsequently, the driving motor 411 is started to drive the driving wheel 410 to rotate, so as to realize the autonomous movement of the mobile ventilation structure 4.

[0036] As the mobile ventilation structure 4 moves, the telescopic air duct 113 will be stretched, thereby driving the positioning ring frame 114 to move on the inner rail plate 112 inside the ventilation storage box 107. When the positioning ring frame 114 moves along the inner side of the inner rail plate 112, the return spring 117 will be compressed, so that the positioning ring frame 114 can move out from the inner side of the inner rail plate 112, achieving the maximum stretch of the telescopic air duct 113.

[0037] When the mobile ventilation structure 4 reaches the designated ventilation position in the tunnel, the telescopic air duct 113 and its positioning ring frame 114 are positioned through a plurality of supporting and connecting frame structures 3. The positioning outer rail frame 301 is sleeved on the outer side of the positioning rail wheel 115 of the positioning ring frame 114 to achieve positioning. Two or more positioning outer rail frames 301 are connected through the docking plate 307 and the docking groove 308, and the adjusting bolt 303 is manually rotated to drive the locking inner plate 302 to fix and lock the positioning rail wheel 115, ensuring the stable position of the positioning ring frame 114 on the positioning outer rail frame 301.

[0038] In addition, by loosening the cross locking bolt 306, the support adjustment plate 304 can be rotated vertically, and the positioning plate 305 can be rotated, and the positioning plate 305 can be fixed to the ground using external bolts to provide support for the telescopic air duct 113 after positioning.

[0039] In the normal ventilation mode, the ventilation fan device 102 is in the positive direction, compressing the air outside the wind tube frame 101 and discharging it into the inside of the ventilation frame 401 through the telescopic air duct 113 to provide ventilation for the tunnel.

[0041] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
