Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to an aerial expansion platform for building construction. Background Art

[0002] In the field of building construction, aerial work platforms are widely used. Especially when carrying out work such as building exterior construction, decoration, and cleaning, the stability and safety of the platform are crucial for construction quality and personnel safety.

[0003] Traditional aerial work platforms usually adopt a fixed structure and rely on the weight of the platform itself to maintain stability. However, this design method has many defects. The stability of the platform is only achieved by weight, lacking flexible adjustment and buffering mechanisms. When the platform contacts the building exterior wall, it is easy to generate impact force due to the lack of an effective buffering system, increasing the risk of platform damage and thus affecting construction safety.

[0004] In aerial construction, the expandability of the platform's working space has always been a difficult problem. When many existing platforms need to increase the working space, the operation methods are cumbersome and inefficient. Especially when the platform needs to quickly adjust the working area to adapt to different construction requirements, traditional platforms often cannot flexibly and quickly complete space expansion. This space limitation not only reduces the operation efficiency but also restricts the working conditions of construction workers, affecting the overall construction progress.

[0005] In addition, the angle adjustment function of the existing platforms in the prior art is relatively single, and the height of most platforms is fixed, unable to flexibly meet the working requirements at different heights. In some complex construction environments, the platform cannot adjust the angle or height according to the working needs, resulting in the operators being unable to operate at the best position, further reducing the working efficiency and comfort.

[0006] In summary, traditional aerial work platforms have significant deficiencies in terms of stability, space expandability, and angle adjustment, and are difficult to meet the increasing requirements for flexibility, efficiency, and safety in building construction. Therefore, the present invention proposes an aerial expansion platform for building construction. Summary of the Invention

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to the appended Figure 1 - appended Figure 3, an embodiment of the present invention provides an aerial expansion platform for building construction, including a platform board 1. Columns 2 are installed at the four corners of the platform board 1. The four columns 2 are connected by a first protection component. A limit groove 17 is formed on the outer wall of the platform board 1. A buffer component is installed in the limit groove 17 through a distance adjustment component, which is used to reduce the impact between the platform board 1 and the building outer wall when the platform board 1 is at a high altitude. Fixed seats 7 are installed on both sides of the bottom of the platform board 1. Two groups of mounting seats two 15 are installed on both sides of the platform board 1. A hydraulic cylinder 16 is rotated in the middle of each mounting seat two 15. The output ends of the two groups of hydraulic cylinders 16 are respectively rotated with a moving sleeve 6. A plurality of sector plates 9 are rotated on the opposite sides of each group of moving sleeves 6. A pedal 11 is installed on the opposite sides of each group of sector plates 9. The fixed seat 7 and the moving sleeve 6 are connected by an angle adjustment mechanism, which is used to control the angle of the pedal 11 for convenient walking of workers. A second protection component is arranged on the outer wall of the moving sleeve 6.

[0030] Please refer to the attached Figure 1 - attached Figure 2 , the first protection component includes two groups of gate one 31. The two groups of gate one 31 are respectively rotated on the opposite sides of the front and rear two columns 2 through mounting parts. Each group of gate one 31 is connected by a door lock one 32. A blocking door two 33 is rotated on the opposite sides of the left and right columns 2 through mounting parts. Each group of blocking door two 33 is connected by a door lock two 34.

[0031] Specifically, during work, in the traditional platform lifting method, the lifting device is used to lift the platform to a high altitude. The staff opens the gate one 31 through the door lock one 32 and enters the platform board 1 for high-altitude operation.

[0032] If it is necessary to expand the use space of the platform, at this time, only need to start the hydraulic cylinder 16 to control the lifting of the moving sleeve 6, so that the auxiliary platform is lifted and parallel to the column 2. At this time, the staff opens the blocking door two 33 through the door lock two 34, and then enters the auxiliary platform to continue working. The auxiliary platform expansion design of the present invention is simple and efficient, can quickly increase the working area during the operation process, and improves the working efficiency.

[0033] Please refer to the attached Figure 2 and attached Figure 5 - attached Figure 7 , the distance adjustment component includes a first driving component motor 18 and an isolation seat 24. Sliding grooves one 25 are respectively opened on the upper and lower outer walls of the isolation seat 24. The isolation seat 24 is penetrated from top to bottom with a sliding groove two 26. The sliding groove one 25 and the sliding groove two 26 are communicated. Sliders 22 are slid in both sliding grooves one 25. Slide rods 23 are installed on the upper and lower sides of the outer wall of the slider 22. The outer part of the slide rod 23 slides in the sliding groove two 26.

[0034] The first driving assembly includes a motor 18, the outside of the motor 18 is installed inside the limit groove 17, a bidirectional screw rod 19 is installed at the driving end of the motor 18, and movable seats 20 are rotatable on both sides of the outside of the bidirectional screw rod 19. One end of an adjusting rod 21 is rotatable in the middle of each movable seat 20, and the two adjusting rods 21 are rotatably connected in the middle, and the other end of the adjusting rod 21 rotates in the middle of the slider 22.

[0035] Specifically, during use, in order to ensure that the platform does not collide with the building's exterior wall and be damaged, the buffer component is brought close to the building's exterior wall by adjusting the distance adjustment component according to the distance between the platform and the building's exterior wall, so that when the platform collides with the building's exterior wall, it can first contact the building's exterior wall, thereby minimizing the impact of the platform and the building's exterior wall. The distance adjustment component mainly starts the motor 18 to drive the bidirectional screw 19 to rotate, and controls the relative or opposite movement of the moving seats 20 on both sides, thereby controlling the cross-connected adjustment rods 21 to perform shearing movement, thereby controlling the slider 22 to slide in the slide groove 1 25, and then driving the upper and lower slide rods 23 to slide in the slide groove 26, thereby pushing the isolation seat 24 close to the building's exterior wall, so that the buffer component is close to the building's exterior wall.

[0036] Please refer to the attached Figure 6 The buffer assembly includes two groups of buffer rods 27. The outsides of the two groups of buffer rods 27 slide on the upper and lower parts of the isolation seat 24 respectively. Buffer pads 28 are installed at both ends of the two groups of buffer rods 27. Spring 1 29 and spring 2 30 are respectively sleeved on both sides of the outside of the buffer rods 27. Spring 1 29 is located between the front buffer pad 28 and the isolation seat 24, and spring 2 30 is located between the rear buffer pad 28 and the isolation seat 24.

[0037] Specifically, when the platform is pushed by external forces and approaches the building's outer wall to collide, the buffer assembly contacts and collides with the building's outer wall in advance, and the buffer pad 28 contacts the building's outer wall first, thereby driving the buffer rod 27 to slide in the middle of the isolation seat 24, thereby driving the buffer pad 28 to squeeze the spring 1 29, and at the same time, the buffer pad 28 on the other side drives the spring 2 30 to stretch, so that the spring 1 29 and the spring 2 30 produce a rebound reaction, thereby reducing the impact force with the building's outer wall and protecting the platform from damage by the impact. Compared with traditional platforms, the prior art lacks buffer assemblies and only relies on weight to ensure the stability of the platform in the air and prevent it from unnecessary shaking. The present invention solves this problem, greatly reduces the risk of platform damage, and enhances the safety of the platform.

[0038] Please refer to the attached Figure 4 The angle adjustment mechanism includes a second driving assembly and an adjusting rod 10. The end of the adjusting rod 10 rotates on the top of the outer wall of the raised plate on the upper surface of the fixed seat 7. The outer walls of multiple fan-shaped plates 9 rotate on the outer wall of the adjusting rod 10. The bottom of the outer wall of the raised plates on both sides of the upper surface of the fixed seat 7 rotates with a movable rod 8, and the outer wall of the movable rod 8 slides inside the movable sleeve 6.

[0039] The second driving component includes two first mounting seats 3, the outer walls of the two first mounting seats 3 are respectively mounted on the tops of the outer walls of two same-side columns 2, electric telescopic rods 4 are rotatably mounted in the middles of the two first mounting seats 3, and the output end of each electric telescopic rod 4 is rotatably mounted on the outer wall of a moving sleeve 6 through a connecting shaft 5.

[0040] Specifically, when working, if it is necessary to expand the use space of the platform, only need to start the hydraulic cylinder 16 at this time to control the lifting of the moving sleeve 6, so that the auxiliary platform is lifted and parallel to the column 2. At this time, the staff opens the second barrier door 33 through the second door lock 34, and then enters the auxiliary platform to continue working. If the staff needs to work at two height positions above and below respectively, they can start the electric telescopic rod 4 to control the moving sleeve 6 to slide on the outer wall of the movable rod 8, thereby driving the sector plate 9 to control the angle adjustment of the pedal 11, so that it is adjusted from the parallel state to the up-and-down step state. At this time, the hydraulic cylinder 16 is started again to control the angle adjustment of the moving sleeve 6 on the fixed seat 7, synchronously drive the position adjustment of the sector plate 9, and at the same time the adjusting rod 10 is adjusted synchronously. At this time, the auxiliary platform is in an inclined state. After the adjustment is completed, the staff can enter the auxiliary platform again. The working position of the staff on the auxiliary platform is lower than that of the staff on the main platform. The present invention enables the auxiliary platform to be adjusted to working positions at different heights according to requirements. Traditional platforms usually can only provide a fixed height and cannot meet the requirements under different working conditions. The design of the present invention allows the staff to flexibly adjust the working angle and height on the auxiliary platform according to actual needs, thereby improving the comfort and flexibility of the work and adapting to a variety of complex construction environments.

[0041] Please refer to the attached Figure 1 - attached Figure 3 The second protection component includes two first fences 12, the bottom ends of the two first fences 12 are respectively rotatably mounted on both sides of the platform board 1, a plurality of moving rods 13 are slidably mounted in the middle chambers of the two first fences 12, a second fence 14 is mounted at the ends of the two groups of moving rods 13, and the bottom end of the second fence 14 is mounted on the outer wall of the moving sleeve 6.

[0042] Specifically, when the auxiliary platform is adjusted, along with the movement of the moving sleeve 6 on the outer wall of the movable rod 8, the second fence 14 is synchronously driven to move, so that the moving rods 13 move in the inner cavity of the first fence 12, thereby enabling the second protection component to adapt to the adjusted auxiliary platform and protecting the staff on the auxiliary platform.

[0043] Working principle: When using the platform of the present invention, it is lifted to a high altitude by a lifting device in the same way as a traditional platform, and the staff stands on the platform to perform high-altitude operations.

[0044] During use, to ensure that the platform does not collide with and be damaged by the building exterior wall, according to the distance between the platform and the building exterior wall, the distance adjustment component is adjusted to move the buffer component closer to the building exterior wall. When the platform collides with the building exterior wall, it can first come into contact with the building exterior wall, minimizing the impact between the platform and the building exterior wall. The distance adjustment component mainly starts the motor 18 to drive the bidirectional lead screw 19 to rotate, controlling the relative movement or reverse movement of the two moving seats 20 on both sides, thereby controlling the shear movement of the cross-connected adjusting rod 21, controlling the slider 22 to slide in the first chute 25, and then driving the upper and lower sliding rods 23 to slide in the second chute 26, thus pushing the isolation seat 24 closer to the building exterior wall and making the buffer component closer to the building exterior wall.

[0045] When the platform is pushed by an external force and approaches and collides with the building exterior wall, at this time, the buffer component comes into contact with and collides with the building exterior wall in advance. At this time, the buffer pad 28 first comes into contact with the building exterior wall, driving the buffer rod 27 to slide in the middle of the isolation seat 24, driving the buffer pad 28 to compress the first spring 29, and at the same time, the buffer pad 28 on the other side drives the second spring 30 to stretch, causing the first spring 29 and the second spring 30 to generate a reactive force of resilience, thereby reducing the impact force with the building exterior wall and protecting the platform from impact damage.

[0046] When working, if it is necessary to expand the use space of the platform, only the hydraulic cylinder 16 needs to be started to control the lifting of the movable sleeve 6, so that the sub-platform is lifted and parallel to the column 2. At this time, the staff opens the barrier door two 33 through the door lock two 34 and enters the sub-platform to continue working. If the staff needs to work at two different height positions respectively, the electric telescopic rod 4 can be started to control the movable sleeve 6 to slide on the outer wall of the movable rod 8, driving the sector plate 9 to control the angle adjustment of the pedal 11, adjusting it from a parallel state to an up-and-down stepped state. At this time, the hydraulic cylinder 16 is started again to control the angle adjustment of the movable sleeve 6 on the fixed seat 7, synchronously driving the position adjustment of the sector plate 9, and at the same time, the adjusting rod 10 is adjusted synchronously. At this time, the sub-platform is in an inclined state. When the sub-platform is adjusted, as the movable sleeve 6 moves on the outer wall of the movable rod 8, the fence two 14 is synchronously driven to move, so that the movable rod 13 moves in the inner cavity of the fence one 12. After the adjustment is completed, the staff can enter the sub-platform again. The working position of the staff on the sub-platform is lower than that of the staff on the main platform.
