Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation duct hoisting technology, specifically, to a ventilation duct hoisting structure. Background Technology
[0002] Ventilation ducts are commonly used metal or non-metal pipes in ventilation and air conditioning projects in industrial and civil buildings. Ventilation ducts are facilities that allow air to circulate within a building. They are typically connected by flanges, clamps, or other rigid methods. Therefore, during installation, ventilation ducts must be hoisted along their direction. The installation structure usually uses expansion bolts and threaded rods to fix the duct to the ceiling, and then crossbeams support the duct.
[0003] However, once the traditional ventilation duct hoisting structure is fixed during installation, it becomes inconvenient to adjust if there are deviations in the vertical or horizontal direction of the pipe sections during later pipe installation. It may even conflict with the hoisting structure, requiring re-drilling and wasting manpower. Utility Model Content
[0004] This utility model proposes a ventilation duct hoisting structure to solve the problem in the prior art that if there are vertical or horizontal deviations in the front and rear pipe sections during the later stages of pipe installation, it will be inconvenient to adjust, and may even conflict with the hoisting structure.
[0005] The technical solution of this utility model is as follows: A ventilation duct hoisting structure includes a fixed plate, a slide rail, a sliding component, a fixing screw, and a support component. The fixed plate can be fixed to the ceiling. The slide rail is fixedly connected to the lower end face of the fixed plate. Two sliding components are slidably arranged on the slide rail. The ventilation duct is placed between the two sliding components. The fixing screw has a threaded hole on each of the two sliding components. The threaded hole is adapted to the fixing screw. When the position of the sliding component on the slide rail is determined, in order to prevent the sliding component from sliding arbitrarily, the fixing screw can be tightened to pass through the threaded hole and press against the slide rail. The support component is connected to the sliding component and is used to support the ventilation duct.
[0006] In order to facilitate the adjustment of the position of the ventilation duct, the sliding assembly includes a slider and a lead screw. The slide rail has a concave-convex structure and is adapted to the slider. The lead screw is fixedly connected to the lower end of the slider.
[0007] To provide cushioning for the ventilation duct, the support assembly includes a support plate and an elastic element. Two support plates are provided, and two lead screws pass through both support plates. The two support plates are connected by the elastic element.
[0008] To facilitate adjustment of the hoisting structure according to the size of the ventilation duct, a hollow through groove is also included. Two circular through holes adapted to the lead screw are opened on both of the support plates. The two circular through holes are connected to form a hollow through groove, which allows the support assembly to slide up and down on the lead screw.
[0009] Preferably, it also includes a plurality of nuts adapted to the lead screw, wherein tightening the plurality of nuts can fix the height of the support plate on the lead screw.
[0010] The working principle and beneficial effects of this utility model are as follows:
[0011] 1. When a positioning error occurs in the ventilation duct, two sliders slide on the slide rail to adjust the displacement of the entire hoisting structure and thus align the ventilation duct.
[0012] 2. When installing ventilation ducts of different sizes, two sliders slide on the slide rail, which drives two lead screws to slide in the hollow groove. Adjust the distance between the two lead screws to place ventilation ducts of different sizes.
[0013] Compared with existing technologies, which involve measuring and positioning, drilling holes with expansion bolts, and then installing the hoisting structure, this method requires disassembly and re-drilling when there is a misalignment between the front and rear pipe sections. In contrast, this invention allows for easier adjustment of the deviation by adjusting the sliding component, and the support component can also be adapted to ventilation ducts of multiple sizes.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0022] like Figures 1 to 4 As shown in this embodiment, a ventilation duct hoisting structure includes a fixed plate 1, a slide rail 2, a sliding component, a fixing screw 4, and a support component. The fixed plate 1 can be fixed to the ceiling. The slide rail 2 is fixedly connected to the lower end face of the fixed plate 1. Two sliding components are slidably arranged on the slide rail 2. The ventilation duct 3 is placed between the two sliding components. The fixing screw 4 has a threaded hole on each of the two sliding components. The threaded hole is adapted to the fixing screw 4. When the position of the sliding component on the slide rail 2 is determined, in order to prevent the sliding component from sliding arbitrarily, the fixing screw 4 can be tightened to pass through the threaded hole and press against the slide rail 2. The support component is connected to the sliding component and is used to support the ventilation duct 3.
[0023] In order to facilitate the adjustment of the position of the ventilation duct 3, the sliding component includes a slider 101 and a lead screw 102. The slide rail 2 has a concave-convex structure and is adapted to the slider 101. The lead screw 102 is fixedly connected to the lower end of the slider 101. The compatibility between the slider 101 and the concave-convex structure of the slide rail 2 allows the slider 101 to slide freely on the slide rail 2 without falling off. The connection between the slider 101 and the lead screw 102 can drive the lead screw 102 to generate displacement when the slider 101 slides, so that it is easy to adjust when there is a positioning deviation.
[0024] To provide cushioning for the ventilation duct 3, the support assembly includes a support plate 201 and an elastic element 202. Two support plates 201 are provided, with two lead screws 102 passing through both support plates 201. The two support plates 201 are connected by the elastic element 202. The elastic element 202 can be a spring or a sheet spring; in this embodiment, a spring is preferred. During long-term use of the ventilation duct 3, factors such as airflow impact and equipment vibration may affect its service life. Therefore, the elastic element 202 is installed between the two support plates 201 for cushioning.
[0025] To facilitate the adjustment of the hoisting structure according to the size of the ventilation duct 3, a hollow through groove 301 is also included. Two circular through holes adapted to the lead screw 102 are opened on both support plates 201. The two circular through holes are connected to form a hollow through groove 301, which allows the support assembly to slide up and down on the lead screw 102. The spacing of the lead screw 102 in the hollow through groove 301 can also be adjusted according to the size of the ventilation duct 3 to facilitate the installation of the ventilation duct 3.
[0026] Preferably, it also includes a plurality of nuts 401 adapted to the lead screw 102, and when the plurality of nuts 401 are tightened, the height of the support plate 201 on the lead screw 102 can be fixed.
[0027] Working principle: When installing the ventilation duct 3, first measure and locate the hole in the ceiling, then use expansion bolts and other materials to fix the through hole in the fixing plate 1 to the ceiling. Then slide the two sliders 101 into the slide rail 2. Adjust the deviation by sliding the two sliders 101 to ensure that they are aligned with the previously installed ventilation duct 3. After determining the position of the two sliders 101, tighten the fixing screws 4 on the sliders 101 to fix the position of the sliders 101.
[0028] First, screw a nut 401 onto each of the two lead screws 102. Then, let the lead screws 102 pass through the hollow through groove 301 to adjust the support assembly to the installation height of the ventilation duct 3. Finally, screw a nut 401 onto each of the two lead screws 102 to fix the support assembly to the installation height. The levelness of the ventilation duct 3 can be adjusted by adjusting the different heights of the nuts 401 on both sides.
[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
