Technical Field

[0001] The utility model relates to the technical field of operation platform vehicles, in particular to an operation platform vehicle for installing air ducts without air. Background Art

[0002] High-altitude air ducts are a kind of ventilation duct system installed at high altitudes, mainly used in the air-conditioning ventilation systems of large buildings such as commercial centers, airports, exhibition halls, etc. High-altitude air ducts are usually made of materials such as thin steel plates, aluminum plates, hard polyvinyl chloride plates, and fiberglass. Their function is to transport air and air mixtures. An installation operation platform vehicle, also known as an aerial work platform vehicle or an aerial work vehicle, is a mechanical device used for high-altitude operations and is often used in construction, maintenance, cleaning, and other work, providing a convenient lifting function to ensure that workers can perform high-altitude operations in a safe environment.

[0003] The traditional installation process of mechanical and electrical pipelines has been difficult to meet the new development needs. When installing mechanical and electrical pipelines in large-space and large-span buildings, several problems are often encountered: First, due to the high clearance, the installation speed is slow, the work efficiency is low, and it is difficult to dock each section after hoisting; second, since the splicing, assembly, and maintenance of mechanical and electrical pipelines are all ultra-high-altitude operations, there are relatively large safety hazards; third, since the installation of mechanical and electrical pipelines also has to be carried out crosswise with the main structure of the building and the interior decoration construction, it is easy to cause problems such as rework or multiple inspections and adjustments. Therefore, in view of the above deficiencies, an operation platform vehicle for installing air ducts without air is proposed to solve the above problems. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to Figures 1 to 3 , an embodiment provided by the present utility model: An air duct installation operation platform cart includes a walkway 1 and a fixed frame 2. Support rods 3 are fixedly connected to the four corners of the outside of the fixed frame 2. The side of the support rod 3 away from the fixed frame 2 is slidably connected to the inside of the walkway 1. Universal pulleys 4 are fixedly connected to the bottoms of multiple support rods 3. The design here uses the support rod 3 to connect the fixed frame 2. Multiple connecting rods 5 are fixedly connected to the top of the fixed frame 2. Multiple triangular rods 6 are fixedly connected to the top of the fixed frame 2. The design here can make the connection between the fixed frame 2 and the support rod 3 more stable and have a stronger bearing capacity by means of the connecting rod 5 and the triangular rod 6. The air duct transportation platform 7 is fixedly connected to the tops of multiple support rods 3. The design here is that the air duct transportation platform 7 is used to place and transport the air duct. Diagonal braces 8 are fixedly connected to the four corners of the bottom of the air duct transportation platform 7. The design here is that the diagonal brace 8 is to provide more stable support for the air duct transportation platform 7. Limit rods 9 are fixedly connected to the bottoms of multiple diagonal braces 8. The design here is that the limit rod 9 is to prevent tipping over;

[0026] Referring to Figures 2 to 4 , the side of the limit rod 9 close to the fixed frame 2 is slidably connected to the outside of the walkway 1. Brackets 10 are fixedly connected to the left and right sides of the outside of the air duct transportation platform 7. A driving assembly is arranged at the bottom of the air duct transportation platform 7. The driving assembly includes a cylinder 11. The design here uses the cylinder 11 as a power source. The top of the cylinder 11 is installed at the bottom of the air duct transportation platform 7. A push rod 12 is fixedly connected to the output end of the cylinder 11. A support plate 13 is fixedly connected to the bottom of the push rod 12. The design here is to drive the displacement of the push rod 12 and the support plate 13 by the cylinder 11.

[0027] Refer to Figures 2 to 4 Figures 2 to 4 , on both the left and right sides of the support plate 13, there are fixedly connected with a first rotating frame 14. On the outside of both first rotating frames 14, there is a rotating plate 15 rotatably connected. On the far sides of both rotating plates 15, there is a second rotating frame 16 rotatably connected. The design here enables the rotating plate 15 to rotate by means of the displacement of the support plate 13. On the front and rear sides inside the air duct transportation platform 7, there is a sliding connection with an extension plate 17, which can drive the extension plate 17 to slide, thereby greatly increasing the bearing area. The top of the second rotating frame 16 is fixedly connected to the bottom of the extension plate 17. On the adjacent sides of both extension plates 17, there is fixedly connected with an inner plate 18. The design here for the inner plate 18 is to ensure the displacement of the extension plate 17 and at the same time provide stable support. The outside of the inner plate 18 is slidably connected inside the air duct transportation platform 7.

[0028] Working principle: Before hoisting the composite air duct, first, four workers need to cooperate with each other to make the corresponding crossbeams and hanging rods. Subsequently, fix the hanging rod hoop above the steel structure in advance. Then, a customized square steel can be spanned above the catwalk 1, fix the hanging point and use a nylon rope to pull the hook of the electric hoist to the hanging point position. At the same time, tie a 30-meter nylon rope with a diameter of 10 mm to the hook position to prevent the composite air duct from colliding with the steel structure. After the preparatory work is completed, the worker controlling the electric hoist hoists the composite air duct at a speed of 8 meters per minute. When the hoisting and transportation reach near the bottom of the catwalk 1, the ground personnel use a 10-mm nylon rope to pull the composite air duct outwards to prevent it from colliding with the catwalk 1. The air duct continues to rise above the catwalk 1. Two workers above the catwalk 1 cooperate to receive the composite air duct and place the composite air duct on the handrail of the catwalk 1. Then, the above operation can be repeated to transport the second air duct above the handrail of the catwalk 1. Then, the first air duct can be lifted to the top of the air duct transportation platform 7, and the composite air duct is transported to the starting position of the catwalk 1. The articulated boom truck cooperates and is fixed above the crossbeam, and the bottom of the crossbeam is kept 1900 mm above the catwalk 1. Then, the first air duct can be connected to the second air duct, thus completing the installation of the air duct. When it is necessary to expand the area of the air duct transportation platform 7, the cylinder 11 can be started. The cylinder 11 drives the push rod 12 and the support plate 13 to move upwards, which can cause the rotating plate 15 to rotate. At this time, as the rotating plate 15 rotates, the extension plate 17 will slide out from inside the air duct transportation platform 7, thereby increasing the bearing area.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
