Description

Technical Field

[0001] This utility model relates to the field of chimney technology, and in particular to a chimney construction hoisting cage. Background Technology

[0002] The main function of a chimney is to draw out fire and smoke, remove fumes, and improve combustion conditions. The chimney effect: High-rise buildings generally have varying numbers of stairwells, ventilation ducts, air supply ducts, smoke exhaust ducts, elevator shafts, and pipe shafts, etc. The principle of smoke exhaust: When the indoor temperature is higher than the outdoor temperature, the indoor hot air, due to its lower density, rises naturally along these vertical channels and seeps out from the upper floors through gaps in doors and windows and various holes. The outdoor cold air, due to its higher density, seeps in from the lower floors to replenish it, thus forming the chimney effect.

[0003] A hanging cage is needed when installing a chimney. However, a regular hanging cage only has an iron frame and does not provide protection against small particles and dust generated during the installation process. In addition, there are no support points for the chimney when it is placed into the hanging cage, making it difficult to place. Utility Model Content

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, the rotating component in the protection mechanism has the function of rotatable adjustment angle. By rotating the grip block, the rotating plate is driven to rotate, which can provide a suitable support point for the chimney. This design solves the problem of the chimney being difficult to place due to the lack of leverage point when being placed into the cage. Regardless of the diameter or shape of the chimney, a suitable angle can be found to contact the rotating plate during the placement process to achieve stable support. This allows the chimney to be placed more easily and accurately on the first bearing plate, improving construction efficiency and reducing potential safety hazards such as chimney slippage caused by improper placement.

[0014] 2. In this utility model, the structural design of the support component makes the entire protection mechanism closely integrated with the main body of the cage.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-4The illustrated chimney construction hoist includes a protective mechanism with the hoist body at its bottom. The protective mechanism comprises a support assembly and two rotating assemblies, with the support assembly positioned at the front ends of the two rotating assemblies. The support assembly includes a second bearing plate 12, two connectors 7, two iron plates 13, two handles 15, and two magnets 17. The two iron plates 13 are fixedly connected to both sides of the second bearing plate 12 and are positioned at the front ends of the two connectors 7. Each connector 7 has a storage opening near its front end. The two magnets 17 are respectively positioned at... Inside the two storage openings, two iron plates 13 are respectively attracted to the front ends of two magnets 17; each of the two rotating components includes a corner plate 1, a first connector 2, a second connector 4, a plug rod 5, a rotating plate 6, and a grip block 16. The plug rod 5 passes through the top of the first connector 2 and the top of the second connector 4. The first connector 2 has an opening, and the second connector 4 is placed in the opening. The second connector 4 is fixedly connected to one side of the rotating plate 6, and the grip block 16 is fixedly connected to the other side of the rotating plate 6. The corner plate 1 is fixedly connected to the opposite side of the first connector 2; the main body of the cage includes a frame. The frame 9 comprises a first bearing plate 10, two first connecting rings 8, and two second connecting rings 11. The frame 9 is fixedly connected to the top of the first bearing plate 10. The two first connecting rings 8 are fixedly connected to the front end of the frame 9, and the second connecting rings 11 are located at the rear end of the first connecting rings 8. The chimney construction cage also includes a fixed plate 3 and multiple rotating blocks 14. The fixed plate 3 is located at the rear end of the multiple rotating blocks 14 and is fixedly connected to the top of the frame 9 near the rear end. The multiple rotating blocks 14 are all fitted onto the top of the frame 9 and can rotate on the frame 9. The multiple rotating blocks 14 are fixedly connected to the bottom of the two rotating plates 6 and the bottom of the second bearing plate 12, respectively. The two second connecting rings 11 are located at the rear end of the fixed plate 3 and are fixedly connected to the fixed plate 3. The fixed plate 3 is located at the rear end of the two first connecting rings 8. Two connecting pieces 7 are fixedly connected to the sides of the frame 9 and are located at the rear end of the two first connecting rings 8. Two corner plates 1 are fixedly connected to the top of the frame 9 near the rear end and are located on both sides of the fixed plate 3. The two corner plates 1 are fixedly connected to the fixed plate 3.After the chimney is moved to the vicinity of the hoisting cage, the handle 15 of the support assembly becomes a key point of leverage for the construction workers to adjust its position. By gripping the handle 15, the workers can precisely control the positional changes of the support assembly in space, raising it to a suitable height to ensure that the chimney can smoothly enter the hoisting cage without being restricted by height and causing collisions or obstructions. Simultaneously, the handle 15 also allows for horizontal angle adjustment of the support assembly, matching its placement direction and angle with the chimney, creating ideal initial conditions for stable placement. In the overall structure of the support assembly, the iron plates 13 on both sides of the second bearing plate 12 are connected to the connector 7 by magnets 17. This connection method not only ensures the stability of the support component's own structure, but also withstands part of the chimney's weight and impact during placement, preventing deformation or displacement of the support component and thus providing a stable support foundation for the chimney. The grip block 16 of the rotating component plays an indispensable role in the chimney placement process. When the construction worker grips the grip block 16 and rotates the rotating plate 6, the second connecting piece 4 fixedly connected to one side of the rotating plate 6 will rotate flexibly within the socket of the first connecting piece 2. The insertion rod 5 ensures the smoothness of the rotation process and the integrity of the structure. Through this rotation, the angle of the rotating plate 6 can be precisely adjusted, providing diverse support points for the chimney. When the chimney is transported above the cage for placement, different shapes... Chimneys of various sizes can be placed at the most suitable angle on the rotating plate 6 according to their own characteristics, greatly reducing the difficulty of chimney placement. After the chimney is placed on the first bearing plate 10, the rotating component can still adjust the angle according to construction needs. For example, if further fine-tuning or fixing of the chimney is required during subsequent construction, the rotating component can change the angle at any time to cooperate with construction personnel to complete various tasks. At the same time, it also ensures the stability of the chimney throughout the construction process, avoiding swaying or displacement of the chimney due to lack of suitable support points, thereby ensuring the safety and smooth progress of construction. After the chimney is placed, the first connecting ring 8 and the second connecting ring 11 of the hoisting cage are connected to the lifting equipment. During the lifting process, the frame 9 of the main body of the cage and the first bearing plate 10 can bear the weight of the chimney, and the various components of the protection mechanism remain stable to prevent the chimney from shaking or slipping during the lifting process. The rotatable characteristics of the rotating component can adapt to the slight displacement of the chimney during the lifting process to a certain extent, ensuring the safety and stability of the entire cage system. During the chimney construction process, the protection mechanism can play a certain protective role for the construction personnel. For example, when small particles or dust fall, the support component and the rotating component can block some of them, reducing the impact on the construction personnel. At the same time, the construction personnel can readjust the angle of the rotating component according to the actual construction needs to facilitate construction operations in different positions.
