Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a construction operation platform for the exterior facade of a building frame structure. Background Technology

[0002] Frame structures (including reinforced concrete frames, steel frames, and hybrid structural systems) are the most mainstream main structural form in modern construction engineering, widely used in residential buildings, commercial complexes, high-rise office buildings, and public facilities. The facade, as the building's "outer garment," undertakes multiple functions such as enclosure, insulation, decoration, and energy conservation. Construction quality directly affects the building's safety, aesthetics, and performance. Facade construction mainly includes: laying external wall insulation layers, installing finishing materials (such as tiles / stone / metal panels / glass curtain walls), sealing door and window frames and curtain wall frames, painting external walls, and installing ancillary facilities such as photovoltaics / shading systems. This is a crucial stage in building construction that is technically intensive, carries high safety risks, and has a significant time commitment.

[0003] The construction of exterior facades for frame structures is characterized by "high-altitude, suspended, and dynamic" operations. During construction, the work platform is a core piece of equipment for ensuring worker safety and improving work efficiency. Mobile work platforms, due to their flexible repositioning, meet the needs of different construction sites to a certain extent and are gradually being used in this field.

[0004] Existing mobile construction platforms mostly rely on bottom wheels or tracks for movement, and are locked in place using wheel self-locking or track slots. This single "bottom-locking" mode does not effectively constrain the platform's overall center of gravity. When the platform carries construction personnel and materials, generating vertical loads, or under horizontal disturbances such as lateral wind loads or personnel collisions, an unbalanced moment can easily form between the bottom locking point and the platform's center of gravity, leading to insufficient overall stability of the platform and thus increasing the risk of overturning and reducing safety. Furthermore, mobile platforms have high requirements for the construction environment. On construction sites with obstacles or uneven ground, the platform's movement and parking are severely restricted, resulting in poor adaptability. Additionally, existing mobile platforms mainly rely on simple railings and dense mesh netting for safety, posing a risk of personnel falling.

[0005] Based on this, this application proposes a construction operation platform for the exterior facade of a building frame structure. Summary of the Invention

[0006] This invention provides a construction platform for the exterior facade of a building frame structure, which solves the problems mentioned in the background art.

[0011] Preferably, an opening and closing door is provided in the middle of one side of the platform body, and a ladder is provided at the bottom of one side of the platform body. The ladder includes a fixed part connected to the platform body and a rotatable part movably connected to the bottom of the fixed part.

Handrails are provided at both ends of one side of the platform body, and the ladder is located between the two handrails. The top of the handrail is located outside the opening and closing door, constraining the opening and closing direction of the opening and closing door.

[0012] Preferably, both the first and second retractable casters include a third electric telescopic rod, a fixed plate connected to the third electric telescopic rod, a rotating tube movably connected to the bottom of the fixed plate, a fixed frame connected to the bottom of the rotating tube, a roller movably connected to the bottom of the inner cavity of the fixed frame, and a self-locking assembly.

[0013] Preferably, the second moving structure includes a fifth electric telescopic rod connected to the moving base, a fixed block connected to the end of the output shaft of the fifth electric telescopic rod, and a double-headed cylinder connected to the top of the fixed block.

[0014] Preferably, there is a height difference between the bottom of the fixing part and the top of the second movable structure, and the fixing part is located above the second movable structure.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. In the construction operation platform for the exterior facade of the building frame structure, when there is an obstacle in front of the first retractable omnidirectional wheel in the direction of movement, the controller of this application can change the position of the second retractable omnidirectional wheel through the second moving structure, drive the second retractable omnidirectional wheel to move laterally or longitudinally until it moves to the area directly in front of the obstacle, and then use the supporting function of the second retractable omnidirectional wheel to transfer part of the platform's load to that position, forming an effective obstacle avoidance, improving the safety of the construction operation platform in dynamic movement, and improving the environmental adaptability of this application.

[0019] 3. The construction platform for the building frame structure facade is further improved by locking both the bottom and top, thereby enhancing the overall support stability of the platform and improving the safety of the construction work. The use of fall arresters to construct a dynamically adjustable fall protection safety barrier can form a horizontal physical barrier during operation, blocking the limbs of workers or operating tools and reducing the probability of personnel or materials falling. It can also be folded up to the edge of the platform to reduce space occupation when moved, thus balancing safety and operational flexibility. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] This invention provides one embodiment: Please refer to Figures 1-7 A construction platform for the exterior facade of a building frame structure includes a movable base 1. Both ends of the bottom of the movable base 1 are connected to a first retractable universal wheel via a linear movement structure. In embodiment 1, the linear movement structure includes a ball screw 35 movably connected to the bottom of the movable base 1. A ball nut is provided on the outer ring of the ball screw 35, forming a high-precision screw-nut pair. A fixing sleeve 36 is fitted around the outer ring of the ball nut, and the first retractable universal wheel is connected to the fixing sleeve 36. Through the linear movement structure, when the ball screw 35 rotates, the ball nut can move in the direction of the ball screw 35. When the ball nut moves, the fixing sleeve 36 drives the first retractable universal wheel to move, thus changing the position of the first retractable universal wheel.

[0024] The first retractable omnidirectional wheel includes a third electric telescopic rod 15 connected to a fixed sleeve 36, a fixed plate 38 connected to the third electric telescopic rod 15, a rotating tube 13 movably connected to the bottom of the fixed plate 38, a fixed frame 29 connected to the bottom of the rotating tube 13, a roller 28 movably connected to the bottom of the inner cavity of the fixed frame 29, and a self-locking assembly. The extension and retraction of the third electric telescopic rod 15 can change the position of the roller 28. When the roller 28 is in contact with the ground, the construction platform is supported by the roller 28, and its position can change under external force. When the roller 28 separates from the ground under the action of the third electric telescopic rod 15, it facilitates the linear movement structure to change the position of the first retractable omnidirectional wheel.

[0025] The self-locking assembly includes a fourth electric telescopic rod 26 connected to the fixed plate 38. The output shaft of the fourth electric telescopic rod 26 axially penetrates the inner cavity of the rotating tube 13 and extends to the top of the inner cavity of the fixed frame 29. The output shaft of the fourth electric telescopic rod 26 is movably connected to the inner cavity of the rotating tube 13, and a locking plate 27 is connected to the end of the output shaft of the fourth electric telescopic rod 26. With the self-locking assembly, when the locking plate 27 moves towards the roller 28 and fits tightly with the telescopic rod as it extends, the static friction force generated at the contact interface between the two will significantly increase until it exceeds the threshold of the tangential force generated by the external force on the roller 28, thereby achieving mechanical locking of the roller 28. Conversely, when the telescopic rod retracts and separates the locking plate 27 from the roller 28, the roller 28 returns to a free-rotating state. The locking assembly effectively ensures the stability of the platform in static operation or positioning states, while also meeting the functional requirement of free rotation of the roller during dynamic movement.

[0026] The bottom of the locking plate 27 is provided with an anti-slip pad. The material of the anti-slip pad can be set according to the requirements and is not limited here. The anti-slip pad can increase the friction between the locking plate 27 and the roller 28 and reduce the impact force when the locking plate 27 and the roller 28 come into contact.

[0027] The bottom of the mobile base 1 is provided with a drive structure, which includes a first servo motor 31 connected to the mobile base 1. The output shaft of the first servo motor 31 is connected to a rotating rod 33. Several transmission gears 30 are movably sleeved on the outer ring of the rotating rod 33. The transmission gears 30 are movably connected to the bottom of the mobile base 1. An electromagnet 32 ​​is embedded in the rotating rod 33. The electromagnet 32 ​​and the transmission gears 30 are in a one-to-one correspondence. When the electromagnet 32 ​​is energized, the electromagnet 32 ​​and the transmission gears 30 are in a magnetic attraction state. At this time, when the first servo motor 31 is working, it can drive the rotating rod 33 to rotate. The rotating rod 33 can drive the transmission gear 30 corresponding to the electromagnet 32 ​​to rotate through the energized electromagnet 32.

[0028] The power input end of the linear motion structure is provided with a driven gear 34 that meshes with the transmission gear 30. That is, in embodiment 1, the outer ring of the ball screw 35 is fixedly connected to the driven gear 34. When the transmission gear 30 rotates, the transmission gear 30 can drive the ball screw 35 to rotate through the driven gear 34 that meshes with it. The position of the first telescopic caster can be changed by using the linear motion structure.

[0029] In Embodiment 2, two transmission gears 30 are movably sleeved on the outer ring of the rotating rod 33. The two linear moving structures at one end of the movable base 1 are driven by the same driving structure, which simplifies the structure and reduces costs.

[0030] Both ends of the top of the movable base 1 are connected to a set of second retractable casters via a second movable structure. The structure of the second retractable casters is the same as that of the first retractable casters, and will not be described in detail here. A vision sensor 14 is provided on the second movable structure. Based on the data collected by the vision sensor 14, the controller of this application can determine whether there is an obstacle in front of the direction of movement, and whether the obstacle can affect the movement of this application.

[0031] The second movable structure includes a fifth electric telescopic rod 17 connected to the movable base 1, a fixing block 18 connected to the end of the output shaft of the fifth electric telescopic rod 17, and a double-headed cylinder 19 connected to the top of the fixing block 18. Each of the two output shafts of the double-headed cylinder 19 is connected to a connecting block 16. The bottom of the connecting block 16 is connected to a second retractable universal wheel. A vision sensor 14 is installed on the outer side of the top of the fixing block 18. The extension and retraction of the fifth electric telescopic rod 17 can change the distance between the second retractable universal wheel and the movable base 1, and the extension and retraction of the double-headed cylinder 19 can change the distance between the two second retractable universal wheels.

[0032] As described above, during the movement of this construction platform, when there is an obstacle in front of the first retractable omnidirectional wheel's direction of movement, the controller of this application can change the position of the second retractable omnidirectional wheel through the second moving structure, driving the second retractable omnidirectional wheel to move laterally or longitudinally until it moves to the area directly in front of the obstacle. Then, utilizing the support function of the second retractable omnidirectional wheel, part of the platform's load is transferred to that position, effectively avoiding the obstacle. Simultaneously, the relative position of the first retractable omnidirectional wheel is precisely controlled through the linear moving structure, creating a spatial misalignment with the obstacle, thereby eliminating the obstacle's obstruction of the platform's movement path and ensuring the platform can smoothly bypass the obstacle and continue moving. Furthermore, in a stationary operating state, the second retractable omnidirectional wheel can actively extend and contact the ground, forming a multi-point support system together with the first retractable omnidirectional wheel. By increasing the effective contact area with the ground, the overall support stability of the platform is significantly improved. This design not only enhances the platform's anti-overturning ability under load conditions but also effectively suppresses minor displacements caused by uneven ground or external interference, providing more reliable safety assurance for construction operations.

[0033] The top of the mobile base 1 is connected to the platform body 3 via a detachable support column 2. Both sides of the bottom of the platform body 3 have slots 11. The inner cavity of each slot 11 is connected to a vacuum suction cup 12 via a first moving structure. The first moving structure includes a first electric telescopic rod 21 connected to the platform body 3 and a second electric telescopic rod 22 connected to the end of the output shaft of the first electric telescopic rod 21. The first electric telescopic rod 21 and the second electric telescopic rod 22 form an L-shaped structure. The end of the output shaft of the second electric telescopic rod 22 is connected to the vacuum suction cup 12. Through the first moving structure, the extension and retraction of the first electric telescopic rod 21 can change the position of the vacuum suction cup 12 within the slot 11, and the extension and retraction of the second electric telescopic rod 22 can change the distance between the vacuum suction cup 12 and the platform body 3. In use, under the action of the first moving structure, the vacuum suction cup 12 can fit tightly against the building frame structure.

[0034] A vacuum pump 20 is installed on the platform body 3. The air inlet of the vacuum pump 20 is connected to the vacuum suction cup 12 through a vacuum tube 23. One end of the vacuum tube 23 is equipped with an electric ball valve 24 and a vacuum sensor 25, with the vacuum sensor 25 located on the side of the electric ball valve 24 closer to the vacuum suction cup 12. By installing the vacuum pump 20, the vacuum suction cup 12 can be connected to the building frame structure under negative pressure when it is working. This allows the top of the construction platform to be fixed in position during use. The platform's stability is improved by locking both the bottom and top. When the vacuum suction cup 12 is connected to the outer surface of the building frame structure under negative pressure, the air passage of the vacuum tube 23 can be blocked by the electric ball valve 24, so that the inner cavity of the vacuum suction cup 12 is in a sealed state, the vacuum pump 20 can stop working, and the vacuum sensor 25 can detect the negative pressure value of the inner cavity of the vacuum suction cup 12 in real time. When the negative pressure is lower than the preset safety threshold, the controller of this application controls the vacuum pump 20 to restart working, and quickly restores and maintains a stable negative pressure adsorption connection between the vacuum suction cup 12 and the building frame structure by replenishing the vacuum, thereby ensuring the reliability and firmness of the connection between the two.

[0035] A fall arrestor 9 is installed on the outer side wall of the top of the platform body 3. The fall arrestor 9 is movably connected to the platform body 3. The rotating shafts of two adjacent fall arrestors 9 are synchronously connected through a bevel gearbox 37. The bevel gearbox 37 reverses the rotational direction of adjacent rotating shafts by 90° and transmits power proportionally, so that the fall arrestors form a linkage control system. A second servo motor 10 is installed on one side of the top of the platform body 3. The end of the output shaft of the second servo motor 10 is connected to the rotating shaft of one of the fall arrestors 9. When the second servo motor 10 starts, its output torque is transmitted sequentially through the mechanical transmission chain: first, it drives the directly connected fall arrestor plate 9 to rotate around the shaft; then, through the cascade transmission of the bevel gear box 37, it sequentially drives the adjacent fall arrestor plates 9 to rotate synchronously in the same direction, ultimately achieving coordinated linkage of all fall arrestor plates 9. Through precise angle control of the servo motor, the deployment angle of each fall arrestor plate can be adjusted synchronously, thereby constructing a dynamically adjustable fall arrest safety barrier. This barrier can form a lateral physical barrier during operation, blocking the limbs of workers or operating tools and reducing the probability of personnel or materials falling; it can also be retracted to the edge of the platform during movement to reduce space occupation, balancing safety and operational flexibility. Furthermore, the second servo motor 10 has a self-locking function, such as using an electromagnetic lock to achieve self-locking, fixing the position of the fall arrestor plate 9 when deployed, ensuring reliable operation.

[0036] A door 4 is provided in the middle of one side of the platform body 3, and a ladder is provided at the bottom of one side of the platform body 3. The ladder includes a fixed part 5 connected to the platform body 3 and a rotatable part 7 movably connected to the bottom of the fixed part 5. A third servo motor 8 is provided on one side of the bottom of the fixed part 5. The rotatable part 7 is driven to rotate by the third servo motor 8. When the third servo motor 8 drives the rotatable part 7 to rotate, the height of the bottom of the rotatable part 7 can be changed. Handrails 6 are provided at both ends of one side of the platform body 3. The ladder is located between the two handrails 6. The top of the handrail 6 is located outside the door 4, which restricts the opening and closing direction of the door 4, so that the door 4 can only open and close inward, so that the door 4 will not open out of control due to external impact, effectively preventing people from falling or materials from scattering.

[0037] There is a height difference between the bottom of the fixed part 5 and the top of the rotatable part 7 and the top of the second movable structure. The tops of the fixed part 5 and the rotatable part 7 are both located above the second movable structure. This arrangement can prevent the ladder from affecting the use of the second movable structure.

[0038] All electrical components involved in this application are existing technologies. Those skilled in the art can select appropriate models of electrical components according to their needs. No restrictions or elaborations are made here. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies are connected by wires. According to the actual situation, appropriate controllers are selected to meet control requirements. For specific connections and control sequences, please refer to the description below. The electrical connections between each electrical component are completed in the order of their operation. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0039] In summary: When the construction platform for the exterior facade of the building frame structure moves, if there is an obstacle in front of the first retractable omnidirectional wheel's direction of movement, the controller of this application can change the position of the second retractable omnidirectional wheel through the second moving structure, driving the second retractable omnidirectional wheel to move laterally or longitudinally until it moves to the area directly in front of the obstacle. Then, utilizing the supporting function of the second retractable omnidirectional wheel, part of the platform's load is transferred to this position, effectively avoiding the obstacle. Simultaneously, the relative position of the first retractable omnidirectional wheel is precisely controlled through the linear moving structure, creating a spatial misalignment with the obstacle, thereby eliminating the obstacle's obstruction of the platform's movement path and ensuring the platform can smoothly bypass the obstacle and continue its journey.

[0040] In a static operating state, the second retractable omnidirectional wheel can actively extend and contact the ground, forming a multi-point support system together with the first retractable omnidirectional wheel. By increasing the effective contact area with the ground, the overall support stability of the platform is significantly improved. The roller 28 is locked using a locking assembly, and the position of the vacuum suction cup 12 is changed using the first moving structure. After the vacuum suction cup 12 is tightly fitted to the building frame structure, the vacuum pump 20 is activated, creating a negative pressure connection between the vacuum suction cup 12 and the building frame structure, thus locking the top of the platform. This platform, by locking both the bottom and top, further improves the overall support stability of the platform, thereby enhancing the safety of construction operations on the exterior facade of the building frame structure.

[0041] Once the platform is locked in position, the second servo motor 10 drives the directly connected fall arrestor plate 9 to rotate around the pivot. Then, through the cascade transmission of the bevel gearbox 37, the adjacent fall arrestor plates 9 are driven to rotate synchronously in the same direction, ultimately achieving coordinated linkage of all fall arrestor plates 9. Through precise angle control of the servo motor, the deployment angle of each fall arrestor plate can be adjusted synchronously, thereby constructing a dynamically adjustable fall arrest safety barrier. This barrier can form a lateral physical barrier during operation, blocking the limbs of workers or operating tools and reducing the probability of personnel or materials falling. It can also be folded up to the edge of the platform during movement to reduce space occupation, thus balancing safety and operational flexibility.
