Description

Technical Field

[0001] This utility model relates to the field of suspended platform technology, and in particular to a suspended platform for building safety exterior wall protection. Background Technology

[0002] With the acceleration of urbanization, high-rise buildings are springing up like mushrooms after rain. In many stages of construction, including exterior decoration, glass curtain wall installation, and building maintenance, efficient and safe aerial work equipment is needed to meet construction requirements. Traditional methods of aerial work, such as scaffolding, are time-consuming and labor-intensive to set up and dismantle, and are inconvenient to operate and relatively unsafe in some complex building structures and high-altitude work scenarios. Suspended platforms, with their flexibility, convenience, and efficiency, are gradually becoming the preferred equipment for aerial work, and the increasing market demand is driving their rapid development.

[0003] For example, in the prior art, a building safety exterior wall protection suspended platform, publication number: CN223358670U, is used by workers standing on top of the base plate. The first electric telescopic rods are installed at the four corners of the base plate. The first electric telescopic rods control the raising and lowering of the square frame, thereby controlling the height of the guardrail composed of several telescopic rods and the square frame. The storage baskets are installed at both ends of the base plate for convenient left and right flexible use by the user. The storage baskets slide on the slide rails to adjust their position. The cover plate covers the storage baskets, and the water buckets and paint cans used are placed inside the storage baskets to prevent liquids from spilling when shaken.

[0004] However, in practical applications, existing technologies rely on electric telescopic rods to adjust the height of guardrails. The height of the guardrail is fixed by the self-locking mechanism of the electric telescopic rod. When the electric telescopic rod is damaged or there is a power outage, it relies solely on the static friction force of the internal motor after power failure to lock. When the guardrail is swaying at a height or subjected to external forces (such as people leaning on it), it may "slowly slide down," causing the guardrail height to decrease unexpectedly and lose its protective function (e.g., if the worker is tall, insufficient guardrail height may lead to a fall), seriously affecting the effectiveness and safety of the device. Summary of the Invention

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a building safety external wall protection basket.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a building safety exterior wall protection suspended platform, comprising a supporting base, wherein each corner of the inner bottom surface of the supporting base is fixedly connected to a supporting rod, and a protective plate is fixedly connected to the outer surface of the supporting base near the L-shaped supporting plates on both sides, and an mounting plate is fixedly connected to the upper end face of each supporting rod, wherein two parallel transmission rods distributed along the short side direction are symmetrically rotatably connected to the upper surface of the mounting plate, and a brake motor with a main shaft fixedly connected to the end face of one of the transmission rods is also fixedly connected to the outer surface of the mounting plate, wherein a take-up roller is fixedly connected to the outer surface of each of the two transmission rods, and a traction rope is provided on each of the take-up rollers, wherein a hollow guardrail base is slidably connected to the outer surface of the supporting rod, wherein an L-shaped supporting plate fixedly connected to the end of the traction rope on the same side is fixedly connected to the upper surface of the hollow guardrail base near the short side position on both sides, and a plurality of railings are fixedly connected to the upper surface of the hollow guardrail base along the long side direction on both sides, and a synchronization mechanism for driving the two take-up rollers to rotate synchronously is also provided on the outer surface of the transmission rod.

[0007] Preferably, the height of both the protective plate and the railing is not less than the specified standard height of 1.2m, and the length of the railing is not less than 1.5 times the internal height of the bearing base. The outer side dimension of the hollow guardrail base is the same as the inner side dimension of the bearing base.

[0008] Preferably, the synchronization mechanism includes a synchronization sprocket, two synchronization sprockets are fixedly connected to the transmission rods on both sides respectively, and a synchronization sprocket is also provided between the two synchronization sprockets.

[0009] Preferably, each of the protective plates and the outer surface of the L-shaped receiving plate are provided with a number of sets of limiting holes, and the limiting holes on both sides are connected with limiting bolts by internal threads.

[0010] Preferably, the limiting holes on the L-shaped receiving plates on both sides are a set, and the limiting holes on the protective plates on both sides are multiple sets arranged in a linear array at equal intervals.

[0011] Preferably, the two outer surfaces of the protective plate on the support base are also fixedly connected with counterweight slots, and each counterweight slot has a receiving slot on its upper surface.

[0012] Preferably, each of the protective plates is symmetrically fixed with two lifting rings.

[0013] Preferably, a canopy is also fixedly connected to the upper surface of the mounting plate.

[0014] Preferably, a safety protection door is provided on one side of the outer surface of the support base.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This utility model first uses a brake motor and a synchronous sprocket transmission mechanism to drive the take-up roller to synchronously raise and lower the traction rope, achieving stable lifting and lowering of the hollow guardrail base along the receiving rod. The synchronous mechanism can tilt the guardrail and ensure reliable adjustment. After the guardrail is adjusted to the target height, a limit bolt is used to pass through the limit hole of the L-shaped receiving plate and the guardrail plate to complete the mechanical locking. The multiple sets of equidistant limit holes of the guardrail plate are adapted to different adjustment heights, and the mechanical locking is not affected by power failure or motor damage. Even if the guardrail is subjected to personnel leaning or external collisions during high-altitude operations, it can prevent "slow sliding" and always maintain a standard protection height of not less than 1.2m, fundamentally solving the safety hazards of traditional solutions failing to protect the guardrail. At the same time, this design can also avoid the traction rope bearing the weight of the guardrail and personnel for a long time, reducing its fatigue wear, extending its service life, and further reducing the risk of equipment failure.

[0016] 2. In this utility model, sandbags, iron blocks and other counterweights can be added to the counterweight grooves on both sides of the bearing base according to environmental factors such as load and wind force, which greatly improves the stability of the suspended platform at high altitudes. Even in windy weather, the swaying amplitude of the suspended platform can be reduced, avoiding workers from being unstable or the equipment from putting extra pressure on the wall / suspension mechanism, thus reducing the risk of equipment damage and work interruption.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] like Figure 1-5 As shown, a building safety exterior wall protection suspended platform includes a support base 1. Each corner of the inner bottom surface of the support base 1 is fixedly connected to a support rod 2. The upper end face of each support rod 2 is fixedly connected to an mounting plate 3. The upper surface of the mounting plate 3 is symmetrically rotatably connected to two parallel transmission rods 4 distributed along the short side. The outer surface of the mounting plate 3 is also fixedly connected to a main shaft and a brake motor 5 fixedly connected to the end face of one of the transmission rods 4. The outer surfaces of the two transmission rods 4 are fixedly connected to take-up rollers 6. Each take-up roller 6 is provided with a traction rope 7. The outer surface of the support rod 2 is also slidably connected to a hollow guardrail base 8. The upper surface of the hollow guardrail base 8 is fixedly connected to L-shaped support plates near the short sides on both sides, which are respectively fixedly connected to the ends of the traction ropes 7 on the same side. The upper surface of the hollow guardrail base 8 is fixedly connected to several railings 10 along the long side on both sides. The outer surface of the transmission rod 4 is also provided with a synchronization mechanism for driving the two take-up rollers 6 to rotate synchronously. The synchronization mechanism includes a synchronization sprocket 11, with the two synchronization sprockets 11 fixedly connected to the transmission rods 4 on both sides, and a transmission chain 12 is also provided between the two synchronization sprockets.

[0022] Further explanation of this solution: When actually using the protective suspended platform, the worker can first stand on the support base 1, and then start the brake motor 5. Since the main shaft of the brake motor 5 is fixedly connected to one of the transmission rods 4, the operation of the motor will drive the transmission rod 4 to rotate. Through the cooperation of the synchronous sprocket 11 and the transmission chain 12 in the synchronization mechanism, the two transmission rods 4 can rotate synchronously, thereby causing the take-up rollers 6 on the two transmission rods 4 to synchronously take up and release the traction rope 7. The end of the traction rope 7 is fixedly connected to the L-shaped receiving plate on the hollow guardrail base 8. The taking up and releasing of the traction rope 7 will cause the hollow guardrail base 8 to slide up and down along the receiving rod 2. The worker can adjust the hollow guardrail base 8 to a suitable position according to the height requirements of the external wall operation, so that the guardrail can provide effective protection for himself. This synchronization mechanism can avoid the hollow guardrail base 8 tilting due to the asynchronous rotation of the two take-up rollers 6, ensuring the stability of the guardrail during the adjustment process. It also ensures that the worker can obtain reliable protection at different working heights, reducing the safety risks caused by improper guardrail position during the operation.

[0023] like Figure 1 and Figure 2 As shown, the height of both the protective plate 13 and the railing 10 is not less than the specified standard height of 1.2m, and the length of the railing 10 is not less than twice the internal height of the bearing base. The outer side dimension of the hollow guardrail base 8 is the same as the inner side dimension of the bearing base 11.

[0024] Further explanation of this solution: when workers are performing exterior wall work, the protective plate 13 and the railing 10 can form a protective area around the load-bearing base 1 with a height of not less than 1.2m, which can effectively prevent workers from falling from the edge of the basket due to accidental body tilting during the work process. Even if workers need to bend over or stand up during the work, they can always be within the protective range. The length of the railing 10 is no less than twice the internal height of the bearing base, so that the railing 10 can provide more comprehensive coverage of the side of the bearing base 1 and avoid blind spots. For example, near the edge on both sides of the bearing base 1, the longer railing 10 can also play a good blocking role to prevent working materials from slipping from the side. At the same time, it further enhances the lateral protection of workers, ensuring that the protection height is always 1.2m or above, so that workers do not have to worry about safety hazards due to insufficient protection when working, and can focus more on the external wall operation, improving the safety and efficiency of the operation. Meanwhile, the inner side dimension of the hollow guardrail base 8 is the same as the inner side dimension of the bearing base 1. When adjusting the position of the hollow guardrail base 8, the hollow guardrail base 8 and part of the railing 10 can stay inside the bearing base 1, avoiding the impact on the workers' operating space due to the excessive overall length of the hollow guardrail base 8 and railing 10, and ensuring that the protected area is always maintained at a standard protection height of 1.2m or above, further ensuring the construction effect and construction safety.

[0025] like Figure 3 and Figure 5 As shown, protective plates 13 are fixedly connected to the outer surfaces of the bearing base 1 near the L-shaped support plates 9 on both sides. Several sets of limiting holes 14 are opened on each protective plate 13 and the outer surface of the L-shaped support plate 9. Limiting bolts 15 are threaded into the corresponding limiting holes 14 on both sides. The limiting holes 14 on the L-shaped receiving plates 9 on both sides are a group, and the limiting holes 14 on the protective plates 13 on both sides are multiple groups and are arranged in a linear array at equal intervals.

[0026] The purpose of this solution is as follows: After the worker adjusts the position of the hollow guardrail base 8 according to the working height, in order to fix the hollow guardrail base 8 and prevent it from sliding freely during operation, the limiting bolt 15 can be passed through the limiting hole 14 on the L-shaped receiving plate 9 and screwed into the corresponding limiting hole 14 on the protective plate 13. Since the limiting holes 14 on the protective plate 13 are arranged in a linear array at equal intervals, the worker can select the appropriate limiting hole 14 for fixing according to the actual height of the hollow guardrail base 8 after adjustment, making the operation flexible and convenient. This fixing method can firmly connect the hollow guardrail base 8 to the bearing base 1, ensuring that even if it is subjected to external force collision or shaking during operation, the hollow guardrail base 8 will not shift, thereby ensuring that the guardrail is always in an effective protective position for the worker, avoiding the failure of protection due to guardrail movement, and providing further protection for the worker's safe operation. Meanwhile, the position of the hollow guardrail base 8 and the railing 10 above it is fixed by the limiting bolt 15, so as to avoid the weight of the staff and the base 1 being borne solely by the traction rope 7, and further avoid fatigue of the traction rope 7 due to long-term stress, thereby extending the service life of the traction rope 7.

[0027] like Figure 1 and Figure 2 As shown, the protective plate 13 on the support base is also fixedly connected to the two outer surfaces of the base, and each counterweight trough 16 has a receiving groove 17 on its upper surface.

[0028] Further explanation of this plan: Before using the protective suspended platform, the staff can add a suitable weight of counterweight blocks, such as sandbags or iron blocks, into the receiving slot 17 of the counterweight block 16 according to the actual load of the platform and the wind force and other factors in the working environment. After adding the counterweight blocks, the overall weight of the entire protective suspended platform can be increased, thereby improving the stability of the platform when working at height. When encountering strong winds, a heavier counterweight can reduce the swaying amplitude of the suspended platform, prevent the platform from swinging violently due to the wind, prevent workers from losing their footing inside the platform, and also reduce the additional pressure on the walls or suspension mechanism caused by excessive swaying, thus reducing the risk of equipment damage.

[0029] like Figure 3 As shown, each protective plate 13 is symmetrically fixed with two lifting rings 18.

[0030] Further explanation of this plan: during the installation, dismantling, or relocation of the protective suspended platform, the lifting ring 18 plays an important role; During installation, the hook of the lifting equipment can be connected to the lifting ring 18 to lift the entire protective basket and install it at the designated external wall working position. The symmetrically arranged lifting rings 18 can ensure that the basket is evenly stressed during the lifting process, avoid tilting or shaking, and ensure the safety and stability of the installation process. When disassembling or moving the suspended platform, the platform is also lifted using lifting ring 18, facilitating disassembly and transportation operations for workers. Furthermore, during routine maintenance, if the suspended platform needs inspection or relocation, lifting ring 18 provides a convenient lifting point, improving the efficiency and safety of maintenance work.

[0031] like Figure 1 As shown, a canopy is also fixedly connected to the upper surface of the mounting plate 3; A safety protection door 20 is provided on one side of the outer surface of the support base.

[0032] Further explanation of this solution: When workers are performing exterior wall work, the canopy 19 can shield them from direct sunlight, especially in hot summer weather. It can effectively reduce the temperature inside the suspended basket and prevent workers from suffering from heatstroke or other discomfort due to prolonged exposure to the sun. This creates a more comfortable working environment for workers and improves the comfort and efficiency of the work. At the same time, the canopy 19 can also provide some protection for workers and tools and materials inside the suspended basket in the event of light rain, preventing rainwater from directly wetting workers or damaging tools and materials, and ensuring that the work can be carried out in a relatively good environment. The safety door 20 facilitates the entry and exit of personnel from the support base 1. When entering the suspended platform, personnel can open the safety door 20 and close it after entering. This effectively prevents personnel from falling from the doorway during operation and also prevents tools and materials from slipping out of the doorway, further enhancing the safety of the suspended platform and ensuring the safety of personnel entering, exiting, and operating.

[0033] The wiring diagram of the brake motor 5 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring arrangement of the brake motor 5 will not be explained in detail. The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may use the disclosed technical content to make changes or modifications to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the scope of the technical solution of this utility model, shall still fall within the protection scope of the technical solution of this utility model.
