[0002] When constructing vertical ducts in ventilation and air conditioning system shafts in building projects, an electric winch must be installed at the top of the ventilation shaft.

[0003] The existing hoisting method generally involves fabricating a short duct section of the same model as the duct to be installed, first securely connecting the winch hook to the short duct, then bolting the short duct to the duct section to be installed. After hoisting it into place and securing the duct section to the support, the connecting bolts between the short duct and the duct section are removed. This process is repeated to complete the installation of the entire duct. This method has significant drawbacks: firstly, the bolted connection between the short duct and the duct to be installed requires multiple tightening and loosening of bolts during hoisting, severely impacting construction efficiency; secondly, the bolts connecting the short duct and the duct to be installed need to be reused multiple times, greatly affecting the strength of the bolt connection and posing a safety hazard. To address the aforementioned problems, a vertical duct hoisting support for ventilation shafts is proposed. Utility Model Content

[0007] Furthermore, the fastener includes two fixing brackets respectively installed on the side walls of the telescopic frame and the limiting frame; a locking screw that can slide through the two fixing brackets; and a nut ring threaded onto the outer wall of the locking screw.

[0008] Furthermore, the drive component includes two support plates respectively disposed on the front side of the front crossbeam; a drive rod rotatably passing through the two support plates at both ends; and a fixing screw threaded onto the outer wall of one of the support plates and abutting against the outer wall of the drive rod.

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.

[0014] Please see Figure 1-4 This utility model provides a vertical duct hoisting bracket in a ventilation shaft, including two horizontal frames 1 and a support rod 2. The two horizontal frames 1 are connected in the middle by the support rod 2. The horizontal frame 1 has a U-shaped plate structure, which provides a channel for the insertion and sliding of the limiting member 4. Lifting lug 3 is located at the middle of the upper end of the support rod 2 and is used to connect the winch hook to facilitate the winch to lift the entire support and air duct. Two limiting pieces 4 can be slidably inserted into both sides of the two crossbars 1; Drive component 5 is located in the center of the front side of the crossbeam 1; Two transmission components 6 are respectively set on both sides of the front of the front cross frame 1 and connected to the limiting component 4 and the driving component 5; The transmission component 6 is used to provide power to the two driving components 5; the two driving components 5 are used to change the distance between the two limiting components 4, thereby applying them to air ducts of different sizes and improving applicability; the limiting components 4 are used to limit the air duct.

[0015] Specifically, refer to Figure 2-3 The limiting component 4 includes two telescopic frames 41 that can be slidably inserted into one side of the two crossbeams 1, and can slide within the crossbeams 1 to adjust their position to accommodate air ducts of different sizes; a limiting frame 42 is set between the two telescopic frames 41, and both the limiting frame 42 and the telescopic frame 41 are U-shaped plate structures, which facilitates the insertion of air duct flanges and limits and fixes the air ducts; the limiting frame 42 is hinged to the two telescopic frames 41 by a hinge 43, which can fold the limiting frame 42 to facilitate the insertion of air duct flanges and make the operation more convenient; the limiting frame 42 and the two telescopic frames 41 are fixed by fasteners 44 to ensure the stability of the limiting frame 42 during use.

[0016] Specifically, refer to Figure 3 The fastener 44 includes two fasteners 441 respectively disposed on the side walls of the telescopic frame 41 and the limiting frame 42, providing a through channel for the locking screw 442; the locking screw 442 slidably passes through the two fasteners 441 and is used to connect the telescopic frame 41 and the limiting frame 42; and a nut ring 443 threaded on the outer wall of the locking screw 442, which can firmly fix the telescopic frame 41 and the limiting frame 42 together by tightening the nut ring 443.

[0017] Specifically, refer to Figure 4The driving component 5 includes two support plates 51 respectively disposed on the front side of the front crossbeam 1, providing rotational support for the driving rod 52; the driving rod 52, which is rotatably passed through the two support plates 51 at both ends, transmits power to the transmission component 6 by rotating the driving rod 52; a fixing screw 53 is threaded on the outer wall of one of the support plates 51 and abuts against the outer wall of the driving rod 52. After the driving rod 52 is rotated to a suitable position, tightening the fixing screw 53 can fix the driving rod 52 and prevent it from rotating arbitrarily.

[0018] Specifically, refer to Figure 4 The transmission component 6 includes a mounting plate 61 disposed on one side of the outer wall of the front crossbeam 1, which provides rotational support for the threaded rod 62; the threaded rod 62, which is rotatably inserted through the mounting plate 61 at one end and connected to the drive rod 52 at the other end, rotates under the drive of the drive rod 52; and a movable block 63 threadedly sleeved on the outer wall of the threaded rod 62. When the threaded rod 62 rotates, the movable block 63 can move along the threaded rod 62. The movable block 63 can slide through the front crossbeam 1 and connect to the telescopic frame 41, thereby causing the telescopic frame 41 to slide and thus changing the spacing of the limiting component 4.

[0019] Working principle In use, first, according to the size of the duct, rotate the drive rod 52 of the drive component 5; the rotation of the drive rod 52 drives the threaded rod 62 of the transmission component 6 to rotate. Since the moving block 63 is threadedly connected to the threaded rod 62 and can slide through the front cross frame 1, the rotation of the threaded rod 62 causes the moving block 63 to move along the threaded rod 62, thereby driving the telescopic frame 41 of the limiting component 4 to slide in the cross frame 1, adjusting the distance between the two limiting components 4 to adapt to the size of the duct and improve the applicability of the bracket. After adjusting the spacing, tighten the fixing screw 53 of the drive component 5 to fix the drive rod 52 and prevent it from rotating; then, fold the limiting frame 42 of the limiting component 4, insert the flange of the air duct into the space formed by the limiting frame 42 and the telescopic frame 41, and then reset the limiting frame 42. Use the locking screw 442 and the nut ring 443 of the fixing component 44 to fix the limiting frame 42 and the telescopic frame 41 to limit the air duct. Afterwards, the bracket is connected to the winch hook through the lifting lug 3, and the winch is used to hoist the air duct into place; after hoisting, there is no need to tighten and loosen the bolts multiple times as in the traditional method, and subsequent fixing operations can be carried out directly.
