Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a hoisting device for air supply ducts in cleanrooms. Background Technology
[0002] Air supply ducts are pipes used in ventilation and air conditioning systems to deliver air or wind to target areas. Typically, these ducts are used for air circulation within buildings to ensure suitable indoor temperature and air quality. Air supply ducts are usually made of metal, PVC, or other materials and are typically round, square, or rectangular. During installation, the air supply ducts are fixed to a hoisting device, which is fixed to the building surface, thus achieving the installation and fixation of the air supply ducts.
[0003] A search revealed that patent announcement number CN219243863U, published on June 23, 2023, discloses an air supply duct installation mechanism, including a hoisting frame. Bolts are installed on both sides of the top of the hoisting frame, and an adjustment component is installed in the middle of the hoisting frame. The adjustment component includes an expansion frame, a placement frame, and fixing screws. The expansion frame is installed in the middle of the hoisting frame, and the placement frame is connected to the middle of the expansion frame. Fixing screws are installed in the middle of the expansion frame and the placement frame. A positioning hole is provided in the middle of the adjustment component. A protective strip is provided at the upper end of the adjustment component, and an adhesive layer is bonded to the middle of the adjustment component. Lifting holes are provided on both sides of the adjustment component, and clips are provided at the top of the lifting holes. By adjusting the component, the expansion frame can be stretched outwards towards the placement frame, effectively expanding its use and facilitating the placement of large ducts in the middle of the expansion frame. The spacing between multiple sets of expansion frames can be adjusted according to the weight of the duct.
[0004] In existing technologies, when adjusting the spacing between the expansion frame and the placement frame, each adjustment component needs to be adjusted, which requires operating multiple fixing screws. At the same time, it is impossible to operate the two clips in the adjustment component simultaneously, making the operation cumbersome. Furthermore, the height of the clips in existing technologies is fixed, which cannot securely fix air supply ducts of different heights, resulting in poor fixing effect.
[0005] To address these issues, we provide a ductwork hoisting device for cleanrooms. Utility Model Content
[0006] The purpose of this utility model is to provide an air supply duct hoisting device for cleanrooms. It uses a bidirectional threaded screw to drive two lower crossbeams closer together, causing the fixing seat to clamp and fix the air supply duct. Furthermore, by adjusting the screw, the fixing plate clamps and fixes the air supply duct. This solves the problems of existing technologies requiring the operation of multiple fixing screws, the inability to simultaneously operate the two clamps in the adjustment assembly, resulting in cumbersome operation, and the inability of existing technologies to securely fix air supply ducts of different heights, leading to poor fixing effect.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0008] This utility model relates to a hoisting device for air supply ducts in cleanrooms, comprising a mounting base, which includes an I-shaped plate. A lower crossbeam is symmetrically arranged on the front and rear sides of the I-shaped plate. A bidirectional threaded screw is located below the lower crossbeam. A rectangular plate is located above the bidirectional threaded screw. Connecting plates are symmetrically arranged on the left and right sides of the rectangular plate. Moving pipes, fixed to the lower crossbeam, are fitted with clearances on the outer sides of the rectangular plate and connecting plates. A fixed seat is located above the lower crossbeam, comprising adjusting screws symmetrically distributed front and rear. An upper crossbeam is located inside the adjusting screws. Multiple telescopic plates are arranged from left to right below the upper crossbeam, and fixed pipes are fitted with clearances on the outer sides of the telescopic plates.
[0009] The present invention is further configured such that the lower walls of both the rectangular plate and the connecting plate are fixedly provided with vertical plates, the vertical plates are fixedly connected to the I-shaped plate, and the bidirectional threaded screw is rotatably connected to the corresponding vertical plate through a bearing.
[0010] The present invention is further configured such that end plates are threadedly connected to both the front and rear of the bidirectional threaded screw, the end plates are fixedly connected to the corresponding moving tube, and a rocker wheel is fixedly provided at the front end of the bidirectional threaded screw.
[0011] The present invention is further configured such that a slider is fixedly provided above the I-shaped plate on the lower wall corresponding to the lower crossbeam, and the slider is slidably connected to the I-shaped plate.
[0012] The present invention is further configured such that each of the four corner positions of the I-shaped plate is rotatably connected to a rotating rod via a bearing, and a threaded sleeve is connected to the external thread on the upper side of the rotating rod, and a mounting plate is fixedly provided at the upper end of the threaded sleeve.
[0013] The present invention is further configured such that an insert block is provided in the internal gap of the lower end of the fixed tube, and the insert block is fixedly connected to the corresponding lower crossbeam.
[0014] The present invention is further configured such that a fixed plate is fixedly provided at the upper end of the telescopic plate, the fixed plate is fixedly connected to the upper crossbeam, the adjusting screw is threadedly connected to the corresponding fixed plate, and the lower end of the adjusting screw is provided with a rectangular block fixed to the fixed tube. The adjusting screw is rotatably connected to the corresponding rectangular block through a bearing.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model uses a bidirectional threaded screw. By rotating the bidirectional threaded screw, the two end plates move closer together, causing the two lower crossbeams to move closer together. Since the fixing tube in the fixing seat is fixed to the surface of the lower crossbeam, when the two lower crossbeams move closer together, all the fixing tubes on both sides of the air supply duct move closer together to clamp and fix the air supply duct. Compared with the prior art, the air supply duct can be fixed simply by rotating the bidirectional threaded screw, making the operation simpler. This solves the problem that the prior art requires operating multiple fixing screws and cannot operate the two clamps in the adjustment component simultaneously, making the operation more cumbersome.
[0017] 2. This utility model, by setting an adjusting screw, drives the corresponding fixing plate to move towards the air supply duct when the adjusting screw rotates, until all the fixing plates contact the upper wall of the air supply duct and maintain a suitable compressive force, thus achieving clamping and fixing of the air supply duct. Compared with the prior art, since the height of the fixing plate can be adjusted, the mounting base can clamp and fix air supply ducts of different heights, improving the fixing effect and solving the problem that the prior art cannot stably fix air supply ducts of different heights, resulting in poor fixing effect.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1
[0029] Please see Figure 1-4 This utility model is a hoisting device for air supply ducts in cleanrooms, including a mounting base 1. The mounting base 1 includes an I-shaped plate 103. Lower crossbeams 106 are symmetrically arranged on the front and rear sides above the I-shaped plate 103. The cross section of the lower crossbeams 106 is U-shaped. A bidirectional threaded screw 105 is provided below the lower crossbeams 106 to drive two end plates 108a to move closer or further apart. A rectangular plate 107 is provided above the bidirectional threaded screw 105. A connecting plate 104 is symmetrically arranged on the left and right sides of the rectangular plate 107. The rectangular plate 107 and the connecting plate 104 have the same size. Moving pipes 108 fixed to the lower crossbeams 106 are provided on the outer sides of the front and rear sides of the rectangular plate 107 and the connecting plate 104 with clearance fit, which can prevent the two lower crossbeams 106 from moving relative to each other in the horizontal direction.
[0030] Specifically, the lower walls of the rectangular plate 107 and the connecting plate 104 are both fixed with vertical plates 107a, which are fixedly connected to the I-shaped plate 103. The bidirectional threaded screw 105 is rotatably connected to the corresponding vertical plate 107a through a bearing. With the above arrangement, when the bidirectional threaded screw 105 rotates, it drives the two end plates 108a to move closer or further away from each other.
[0031] The bidirectional threaded screw 105 is threaded with end plates 108a at both the front and rear. The end plates 108a are fixedly connected to the corresponding moving tubes 108. The front end of the bidirectional threaded screw 105 is fixed with a rocker wheel 105a. Rotating the rocker wheel 105a will drive the bidirectional threaded screw 105 to rotate. With the above configuration, when the end plates 108a move, the moving tubes 108 on both sides move, which in turn moves the two lower crossbeams 106, ultimately achieving the effect of moving the fixed tube 204.
[0032] A slider 106b is fixedly provided above the I-shaped plate 103 corresponding to the lower wall of the lower crossbeam 106. The slider 106b is slidably connected to the I-shaped plate 103. When the lower crossbeam 106 moves, the slider 106b slides relative to the I-shaped plate 103. The slider 106b fills the space between the lower crossbeam 106 and the I-shaped plate 103 to prevent the lower crossbeam 106 from deforming or bending.
[0033] At each of the four corners of the I-shaped plate 103, a rotating rod 102 is rotatably connected via bearings, causing the rotating rod 102 to rotate. A threaded sleeve 101 is connected to the external thread on the upper side of the rotating rod 102. With the cooperation of the threaded sleeve 101, the height of the corresponding end of the I-shaped plate 103 can be adjusted so that the upper wall of all moving pipes 108 is in contact with the air supply pipe. An installation plate 101a is fixed at the upper end of the threaded sleeve 101. The installation plate 101a has evenly spaced installation holes. Bolts can be used to fix the mounting seat 1 to the building surface through these installation holes.
[0034] It should be noted that, in order to prevent the connecting rod and the bidirectional threaded screw 105 from rotating due to the vibration generated by the airflow during air supply, the outer peripheral wall of the screw sleeve 101 is also threaded with a bolt. After the angle of the mounting base 1 is adjusted, the rotating rod 102 can be prevented from rotating by abutting the bolt with the corresponding rotating rod 102. At the same time, the side wall of any end plate 108a is also threaded with a bolt. After the air supply duct is clamped, the bolt can be abutted with the bidirectional threaded screw 105 to prevent the bidirectional threaded screw 105 from rotating by abutting.
[0035] The operation process of this embodiment is as follows: First, according to the actual installation position, screw holes are drilled on the surface of the building. Then, the mounting base 1 is operated to move the mounting plate 101a to the screw hole position. The mounting plate 101a is fixed to the building by screws to complete the installation.
[0036] Next, place the air supply duct in the installation position above the two lower crossbeams 106, and make the lower wall of the air supply duct contact the upper wall of the moving pipe 108. At this time, operate the rocker wheel 105a to rotate, which drives the bidirectional threaded screw 105 to rotate, thereby driving the two end plates 108a to move closer to each other, which in turn causes the two lower crossbeams 106 to move closer to each other, and finally drives all the fixed pipes 204 to abut against the side wall of the air supply duct.
[0037] Example 2
[0038] Please see Figure 1 , 2 5. This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: a fixed seat 2 is provided above the lower crossbeam 106. The fixed seat 2 includes adjusting screws 203 symmetrically distributed front and rear. An upper crossbeam 201 is provided on the inner side of the adjusting screws 203. The movement of the upper crossbeam 201 drives the corresponding multiple fixed plates 202a to move. Multiple telescopic plates 202 are provided below the upper crossbeam 201 from left to right. The multiple telescopic plates 202 simultaneously apply force to the air supply duct to press it. A fixed pipe 204 is provided with a gap fit on the outside of the telescopic plate 202, so that the telescopic plate 202 and the fixed pipe 204 can only move up and down.
[0039] Specifically, an insert 106a is provided in the internal gap of the lower end of the fixed tube 204. The insert 106a is fixedly connected to the corresponding lower crossbeam 106. The above arrangement improves the anti-tilting ability of the fixed tube 204 and the lower crossbeam 106 through the insert 106a.
[0040] A fixed plate 202a is fixedly provided at the upper end of the telescopic plate 202. The lower wall of the fixed plate 202a is in contact with the upper wall of the air supply duct. The fixed plate 202a is fixedly connected to the upper crossbeam 201. The adjusting screw 203 is threadedly connected to the corresponding fixed plate 202a. The lower end of the adjusting screw 203 is provided with a rectangular block 204a fixed to the fixed pipe 204. The adjusting screw 203 is rotatably connected to the corresponding rectangular block 204a through a bearing. With the above configuration, by rotating the adjusting screw 203, the fixed plate 202a can be moved, and the air supply ducts of different heights can be stably fixed.
[0041] It should be noted that, in order to prevent the adjusting screw 203 from rotating on its own, a bolt is threaded on one side of the fixing plate 202a that is threaded to the adjusting screw 203. After the air supply duct is tightened, the bolt is made to abut against the adjusting screw 203 to prevent the adjusting screw 203 from rotating on its own.
[0042] The operation process of this embodiment is as follows: After fixing the air supply duct with the mounting base 1, the rocker wheel 203a is operated to drive the adjusting screw 203 to rotate, so that the corresponding fixing plate 202a moves down. Under the action of the upper crossbeam 201, all fixing plates 202a on the same side move down until the fixing plate 202a applies appropriate squeezing force to the air supply duct to fix the air supply duct stably.
