Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 ;

[0026] An auxiliary device for the construction of a smoke exhaust ventilation duct includes a support frame 1, with casters 11 installed at the bottom of the support frame 1 for moving the entire device. A first support mechanism 2 is provided on the support frame 1 for supporting the installation of the smoke exhaust ventilation duct. A second support mechanism 3 is provided on the support frame 1 for fine-tuning the position of the smoke exhaust ventilation duct during installation.

[0027] The first support mechanism 2 includes a first opening 21, a second opening 211, a first screw 22, and a first guide rod 221. The first opening 21 is located at one end of the support frame 1, and the second opening 211 is located at the other end of the support frame 1. The first screw 22 is rotatably installed in the first opening 21, and its rotation drives the moving plate 31 to move up and down. The first guide rod 221 is installed in the second opening 211, and its rotation guides the moving plate 31. A first support base 23 is installed on the top of the support frame 1, and the first support base 23 supports and installs the geared motor 25. A cover plate 231 is hinged to the top of the first support base 23, and the geared motor 25 is installed at the bottom of the first support base 23. The geared motor 25 drives the first gear 24 to rotate, and its output end is connected to the first gear 24. The upper end of the first screw 22 is connected to the second gear 241. The first gear 24 and the second gear 241 are located inside the first support base 23 for protection, and the second gear 241 meshes with the first gear 24. The first gear 24 drives the second gear 241 to rotate, and finally the second gear 241 drives the first screw 22 to rotate. A support rod 26 is welded to the side of the support frame 1. The support rod 26 is used not only for workers to climb on but also for supporting the first support plate 27. The upper end of the support rod 26 is snapped into the first support plate 27. The support rod 26 has snap-fit ​​holes, and the protrusions at the bottom of both ends of the first support plate 27 are snapped into these holes. Because the first support plate 27 is snapped in, it is easy to remove and install at any time. The first support plate 27 is used for... For workers to stand on, making it convenient for them to install the smoke exhaust ventilation duct, counterweights 28 are installed at both ends of the support frame 1. When workers stand on the first support plate 27 and the second support mechanism 3 is raised, the counterweights 28 are used to increase the stability of the support frame 1. A storage battery 29 is installed on the upper end of the counterweight 28. The storage battery 29 is used to provide power to the geared motor 25. A geared motor switch is installed at one end of the support frame 1. The storage battery 29 is electrically connected to the geared motor switch, and the geared motor switch is electrically connected to the geared motor 25.

[0028] Furthermore, the second support mechanism 3 includes a movable plate 31, a second support base 32, and a second support plate 34. One end of the movable plate 31 is threadedly connected to a first screw 22, and the other end is slidably connected to a first guide rod 221. The movable plate 31 is used to support the raised installation of the smoke exhaust ventilation duct. The second support base 32 is fixedly installed on the upper end of the movable plate 31 and is used to support the installation of the second guide rod 33. The second support plate 34 is slidably disposed inside the upper end of the second support base 32. The upper end of the second support plate 34 is used to place and support the smoke exhaust ventilation duct. The second guide rod 33 is installed inside the second support base 32 and is used to guide the sliding block 35 to slide, making it easier for the second support plate 34 to move horizontally for fine-tuning, thereby supporting the fine-tuning of the smoke exhaust ventilation duct position. The sliding block 35 is fixedly installed at the bottom of the second support plate 34, and the sliding block 35 is slidably connected to the second guide rod 33. The second support plate 34 is moved and finely adjusted. A bolt is threaded on the front end of the second support plate 34. After the bolt is tightened, the lower end of the bolt will tightly abut against the upper end of the second support seat 32 to temporarily limit the second support plate 34 and prevent it from sliding within the second support seat 32. A third support plate 36 is fixedly installed on the top of both ends of the second support plate 34. The third support plate 36 is used to support the installation of the second screw 37. The second screw 37 is threaded on the inner wall of the third support plate 36. A turntable 38 is installed on one end of the second screw 37 to facilitate the rotation of the second screw 37. The other end of the second screw 37 is rotatably connected to a limiting plate 39. After the second screw 37 rotates, it pushes the limiting plate 39. The limiting plate 39 limits the smoke exhaust ventilation duct supported on the upper end of the second support plate 34 to prevent the smoke exhaust ventilation duct from becoming unstable during the upward process.

[0029] The working principle of this utility model is as follows: The support frame 1 is moved to a designated position, the caster 11 is braked, and the moving plate 31 is lowered to its lowest position to facilitate the placement of the exhaust ventilation duct on the second support plate 34. The turntable 38 is rotated, driving the second screw 37 to rotate. The second screw 37 pushes the limiting plate 39, which limits the exhaust ventilation duct supported on the upper end of the second support plate 34, preventing instability during the upward movement of the duct. A bolt is threaded onto the front end of the second support plate 34. After tightening the bolt, the lower end of the bolt will tightly abut against the upper end of the second support seat 32, temporarily limiting the second support plate 34 and preventing it from sliding within the second support seat 32. Then, the geared motor switch is pressed to start the geared motor 25, which drives the first gear 24 to rotate. The first gear 24 then drives the second gear... 241 rotates, and finally the second gear 241 drives the first screw 22 to rotate, thereby driving the moving plate 31 to move upward. The other end of the moving plate 31 is guided by the first guide rod 221, and the smoke exhaust ventilation duct rises to the appropriate position, so that the height of the smoke exhaust ventilation duct is moved to the same height as the previous connecting duct. The first support plate 27 is snapped onto the support rod 26. The worker climbs and stands on the first support plate 27. If the height is not aligned, it is fine-tuned. If the horizontal position of the smoke exhaust ventilation duct is not aligned, the bolts at the front end of the second support plate 34 are loosened, and the second support plate 34 is pushed and guided to slide in the second support seat 32, thereby fine-tuning the position of the smoke exhaust ventilation duct on the second support plate 34, so that the smoke exhaust ventilation duct interface is aligned with the previous smoke exhaust ventilation duct interface, which facilitates the connection and installation of the smoke exhaust ventilation duct. After the smoke exhaust ventilation duct is installed, the limiting plate 39 can be disengaged.

[0030] In summary, by setting up an auxiliary device for the construction of smoke exhaust ventilation ducts, the second support plate can automatically support the lifting and installation of the smoke exhaust ventilation ducts. Moreover, the second support plate can also move horizontally to fine-tune the position at the connection port of the smoke exhaust ventilation ducts. This not only facilitates the connection and installation of the smoke exhaust ventilation ducts, but also eliminates the need for constant manual support, making the installation more time-saving, labor-saving, and convenient.
