Description

Technical Field

[0001] This invention relates to the field of indoor aerial work platform technology, specifically to a large indoor aerial work platform with isolated suspension. Background Technology

[0002] The existing methods for indoor high-altitude construction mainly involve erecting scaffolding and using aerial work vehicles. As the height increases, the danger and cost of scaffolding increase rapidly. When the indoor working height is above 15 meters, the erection and dismantling of construction scaffolding becomes more difficult, consumes more materials and labor, and occupies indoor space, making it impossible to organize other indoor work. Due to the limitations of the operating platform, vehicle geometry and weight, aerial work vehicles are only suitable for single-point outdoor high-altitude work. They are not convenient for large-scale indoor work such as interior decoration and installation, especially for indoor work exceeding 15 meters in height, where the danger of traditional methods and mechanical construction increases significantly.

[0003] When using suspended aerial work platforms, electric hoists are used in conjunction with a double-rope system for hoisting. However, using only double-rope hoisting results in poor stability, posing potential safety risks to construction workers. Furthermore, at heights, the platform lacks external protective features, making it difficult to guarantee the safety of workers during external operations. Therefore, we propose a large indoor suspended aerial work platform with isolation features.

[0004] Combining the above issues, we find that the existing large indoor aerial work platforms with isolation suspension on the market are difficult to avoid the problems mentioned above at the same time. Even if they can be solved, they require the use of external tools, which cannot achieve the desired effect. Therefore, we propose a large indoor aerial work platform with isolation suspension.

Detailed Implementation

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Please see Figures 1-9 The present invention provides a technical solution: a large indoor high-altitude work platform with isolation suspension, including a main body 1, the main body 1 including a suspension platform 11, an integrated suspension rope 12 is provided above the suspension platform 11, two sets of fixing buckles 17 are provided at the bottom of the integrated suspension rope 12, a hook 16 is provided on the outside of the integrated suspension rope 12, a hoist 13 is fixedly installed at the top of the hook 16, a support beam 14 is provided inside the hoist 13, two mounting platforms 15 are fixedly installed on the bottom surface of the support beam 14, two sets of suspension rope fixing plates 18 are fixedly installed on the upper surface of the suspension platform 11 in a rectangular shape, a moving platform 19 is provided above the suspension platform 11, and a protective mechanism 2 is provided in the lower middle part of the suspension platform 11;

[0034] The protective mechanism 2 includes a fall protection unit 21, which is located in the middle of the suspension platform 11 and is used to support and protect the outside of the suspension platform 11.

[0035] As a further definition of the protective mechanism 2 of the present invention, the fall protection unit 21 includes two sets of fall protection nets 2101, a storage and installation groove 2113, and two sets of receiving grooves 2104. Each set of receiving grooves 2104 is formed on the inner bottom wall of the storage and installation groove 2113. The end of each set of fall protection nets 2101 near the suspension platform 11 is fixedly connected to the inner bottom wall of the storage and installation groove 2113. Each set of fall protection nets 2101 has a different size according to the length and width of the suspension platform 11. The end of each set of fall protection nets 2101 away from the suspension platform 11 has a certain curvature. Two sliders 2110 are fixedly installed on the bottom surface of each set of fall protection nets 2101. Each slider 2110 is slidably connected to an arc-shaped electric slide rail 2109. Each arc-shaped electric slide rail 2109 is located inside the receiving groove 2104. A connecting plate 2 is fixedly installed on the side of each arc-shaped electric slide rail 2109 near the suspension platform 11. 108. A movable plate 2106 is fixedly installed on the upper surface of each connecting plate 2108. A matching nut 2112 is fixedly installed on the inner wall of each movable plate 2106. A screw rod 2111 is threadedly connected to the inner wall of each matching nut 2112. A drive motor 2103 is fixedly installed at the end of each screw rod 2111 away from the suspension platform 11. A limit plate 2102 is fixedly installed on the side of each drive motor 2103 near the suspension platform 11. The side of each limit plate 2102 away from the movable plate 2106 is fixedly connected to the inner wall of the storage installation groove 2113. Each movable plate 2106 is located inside the limit plate 2102. The fall protection unit 21 can be extended and retracted according to the usage requirements. The number of fall protection nets 2101 used is selected according to the construction surface on the suspension platform 11. The external protection of the suspension platform 11 is installed to improve the safety of external construction when the suspension platform 11 is in use.

[0036] Each limiting plate 2102 has a first bearing 2107 fixedly embedded inside. The inner wall of the first bearing 2107 is fixedly connected to the output end of the drive motor 2103. A second bearing 2105 is fixedly installed on the end of the screw 2111 near the suspension table 11. The second bearing 2105 is installed on the inner wall of the suspension table 11. The first bearing 2107 and the second bearing 2105 support the rotation of the screw 2111, reducing the coefficient of friction between the drive motor 2103 and the screw 2111 during the movement process, and ensuring its rotational accuracy.

[0037] The specific implementation method of this embodiment is as follows: When the suspension platform 11 is suspended at a height for construction, the use of the fall arrest net 2101 is selected according to the surface of the suspension platform 11. One side of the suspension platform 11 contacts the wall surface, and the distance between the suspension platform 11 and the wall is small, so construction workers will not have accidents on this side. The other sides of the suspension platform 11 are suspended in the air. To ensure safety during the construction process, the fall arrest net 2101 is deployed as needed. When a construction worker accidentally falls from the suspension platform 11, he / she is trapped on the fall arrest net 2101. The fall arrest net 2101 is driven by the slider 2110 and has a certain supporting strength after extension. When it is necessary to retract the fall arrest net 2101, the arc-shaped electric slide rail 2109 is activated. The curved electric slide rail 2109 starts the slider 2110 to move, and the slider 2110 drives the fall protection net 2101 to move towards the suspension platform 11. After the fall protection net 2101 is completely retracted, the curved electric slide rail 2109 is retracted, the drive motor 2103 is started, and the drive motor 2103 drives the screw 2111 to rotate. The screw 2111 rotates in conjunction with the matching nut 2112, converting the rotational motion of the screw 2111 into the linear motion of the matching nut 2112. The curved electric slide rail 2109 is moved through the moving plate 2106 and the connecting plate 2108, and the curved electric slide rail 2109 is retracted into the storage slot 2104. The protection of the fall protection net 2101 is selected according to the construction requirements.

[0038] Please see Figures 1-9 The present invention provides a technical solution: a large indoor high-altitude work platform with isolation suspension. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0039] As a further limitation of the protective mechanism 2 of the present invention, the protective mechanism 2 also includes a stabilizing unit 22, which is located above the suspension platform 11 and is used to stabilize the hoisting and lifting when the suspension platform 11 is suspended.

[0040] The stabilizing unit 22 includes several adjusting stabilizing rods 2201, which are rectangularly distributed above the four corners of the suspension platform 11. Each adjusting stabilizing rod 2201 has a threaded rod 2202 fixedly installed at its bottom end. Each adjusting stabilizing rod 2201 has a threaded groove 2205 on its upper surface, and each threaded rod 2202 is threadedly connected to the threaded groove 2205. A rotating plate 2206 is fixedly installed at the top end of each top adjusting stabilizing rod 2201. Limiting nuts 2203 are provided above and below the rotating plate 2206. The inner wall of each limiting nut 2203 is threadedly connected to the outer surface of the adjusting stabilizing rod 2201. A wire hole 22 is provided on the upper surface of each rotating plate 2206. 08. Each wire hole 2208 is equipped with a working rope 2209 and an installation rope 2210. The top of each working rope 2209 and the top of each installation rope 2210 are located inside the fixing buckle 17. The working rope 2209 and the installation rope 2210 are suspended in the fixing buckle 17 by the lifting ring. The main body 1 adopts an isolated suspension method, and each lifting point uses double rope safety for lifting operation. The stabilizing unit 22 plays a role in stabilizing the double rope hoisting, which is beneficial to the stability of the suspension platform 11 during the lifting process, reduces the large swaying of the suspension platform 11 and the double rope, and improves the safety of the suspension platform 11, so as to avoid the large safety hazards caused by the deterioration of the stability of the double rope when suspended at a high height.

[0041] Protective washers 2204 are provided on the side of the two limit nuts 2203 that are close to each other. The side of the two protective washers 2204 that are close to each other are in contact with the upper and lower surfaces of the rotating plate 2206, respectively. By providing protective washers 2204, the surface of the parts is protected from damage and has a certain anti-loosening effect.

[0042] Each wire hole 2208 has an anti-wear pad 2207 fixedly installed on its inner wall, and each working rope 2209 and installation rope 2210 is located inside the anti-wear pad 2207; the anti-wear pad 2207 reduces the friction between the working rope 2209 and the installation rope 2210, and improves the service life of the working rope 2209 and the installation rope 2210.

[0043] The specific implementation method of this embodiment is as follows: When hoisting the suspension platform 11, the working hoisting rope 2209 and the installation hoisting rope 2210 are used in conjunction with the integrated hoisting rope 12 for hoisting. The working hoisting rope 2209 and the installation hoisting rope 2210 are suspended at four points. The working hoisting rope 2209, the installation hoisting rope 2210 and the integrated hoisting rope 12 are connected and fixed using fixing buckles 17. Different models of fixing buckles 17 are selected according to requirements. The lower ends of the working hoisting rope 2209 and the installation hoisting rope 2210 are connected to the suspension platform 11 through the hoisting rope fixing plate 18. When hoisting is used, the hoisting hoist 13 is started. The hoisting hoist 13 lifts the suspension platform 11 through the hook 16 and the integrated hoisting rope 12. When the integrated hoisting rope 12 is lifted by the hook 16, the working hoisting rope 2209, the installation hoisting rope 2210 and the integrated hoisting rope 12 are connected and fixed using fixing buckles 17. 9 and the installation rope 2210 will be pulled towards the hook 16. The traction force causes the suspension platform 11 to be unstable. In order to ensure the stability of the working rope 2209 and the installation rope 2210, and thus the stability of the suspension platform 11, an adjustable stabilizing rod 2201 of the same height is installed according to the height of the working rope 2209 and the installation rope 2210. With the help of the rotating plate 2206, the wire hole 2208 and the anti-wear pad 2207, the working rope 2209 and the installation rope 2210 will not tilt too much, and the stability of the working rope 2209 and the installation rope 2210 during lifting is improved. The adjustable stabilizing rod 2201 can be adjusted to the working height according to the cooperation of the threaded rod 2202 and the threaded groove 2205.

[0044] Please see Figures 1-9 The present invention provides a technical solution: a large indoor high-altitude work platform with isolation suspension. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0045] As a further limitation of the fixing mechanism 3 of the present invention, a fixing mechanism 3 is provided below the stabilizing unit 22. The fixing mechanism 3 is located between the anti-fall unit 21 and the stabilizing unit 22. The fixing mechanism 3 is used to fix the suspension platform 11 when the anti-fall unit 21 is used, and to fix the position of the suspension platform 11 after the stabilizing unit 22 is adjusted in height.

[0046] The fixing mechanism 3 includes several support plates 301. The bottom surface of each support plate 301 is in contact with the upper surface of the suspension platform 11. Several stop bars 310 are fixedly installed on the upper surface of the suspension platform 11. Each support plate 301 has two mounting holes 302 on its upper surface. The inner wall of each mounting hole 302 is fixedly connected to the outer surface of the stop bar 310. Each support plate 301 has a rotating plate 305 inside. A support shaft 304 is fixedly installed on the inner wall of each rotating plate 305. A rotary motor 303 is fixedly installed at the end of each support shaft 304 away from the rotating plate 305. Each rotary motor 303 is mounted on the support plate 301. Each rotating plate 305... Hydraulic push rods 306 are fixedly installed on the inner side walls of each hydraulic push rod 306. A push plate 307 is fixedly installed on the telescopic end of each hydraulic push rod 306 away from the support plate 301. Two electric suction cups 308 are fixedly installed on the inner wall of each push plate 307. The fixing mechanism 3 is used for the stable use of the fall protection unit 21 and the stabilizing unit 22. When the fall protection unit 21 is in use, the fixing mechanism 3 fixes the suspension platform 11. By using the electric suction cups 308 and other structures, the suspension platform 11 is fixed to the construction wall, which helps to ensure the safety of the suspension platform 11 after the fall protection unit 21 and the stabilizing unit 22 are used. Together with the fall protection unit 21 and the stabilizing unit 22, it further ensures the safety of construction personnel on the suspension platform 11.

[0047] A platform 309 is fixedly installed on the upper surface of the suspension platform 11. The bottom surface of the platform 309 is fixedly connected to the upper surface of the stop bar 310. The lower end of each threaded rod 2202 located at the bottom is threadedly connected to the platform 309. The platform 309 serves as protection above the suspension platform 11, and the height between the suspension platform 11 and the platform 309 is the safe construction height.

[0048] Several fixing plates 311 are fixedly installed on the upper surface of the table 309, and each fixing plate 311 is located above the rotating plate 305. The rotating plate 305 is fixed by the fixing plates 311, so that when the rotating plate 305 is not in use, it can be retracted to the outside of the table 309 to prevent the rotating plate 305 from occupying space.

[0049] Each fixed plate 311 has two locking rods 313 threadedly connected to its inner wall. Each locking rod 313 has a fastening washer 312 rotatably installed at one end close to the other. By setting the locking rods 313 and the fastening washer 312, tightening the locking rods 313 will fix the rotating plate 305 in conjunction with the fastening washer 312.

[0050] The specific implementation method of this embodiment is as follows: After adjusting the fall arrestor unit 21 and the stabilizing unit 22 to suitable construction positions, in order to ensure the stability of the suspension platform 11 and the safety during construction, according to the building structure at the construction location, a suitable position for the electric suction cup 308 is selected, and the hydraulic push rod 306 is activated. The hydraulic push rod 306 drives the electric suction cup 308 to move, moving the electric suction cup 308 onto the building structure. After the electric suction cup 308 is pressed against the surface of the building structure, the hydraulic push rod 306 stops moving, and the electric suction cup 308 is activated, adhering to the building structure, ensuring that one side of the suspension platform 11 is protected by the support of the support unit 21 and the stabilizing unit 22. The electric suction cup 308 is used to fix the suspension platform 11 so that it will not be shaken too much when it falls onto the fall arrest net 2101. When the electric suction cup 308 is not needed to fix the suspension platform 11, the hydraulic push rod 306 is used to drive the electric suction cup 308 back to the rotating plate 305. The rotating plate 305 can also be retracted so that it does not occupy space. The rotary motor 303 is started and controlled to reverse. The rotary motor 303 drives the rotating plate 305 to rotate via the support shaft 304, rotating the rotating plate 305 into the fixing plate 311, so that the locking rod 313 and the fastening washer 312 further fix the rotating plate 305.
