Construction auxiliary equipment for exterior wall decoration curtain wall structure

Abstract

The application relates to the field of high-altitude operation equipment, in particular to a construction auxiliary equipment for an outer wall decoration curtain wall structure, which comprises a fan assembly and a transmission assembly. The fan assembly comprises a fixing frame, a shell and a fan blade. The shell can slide relative to the fixing frame, so that the rotation point of the shell and the fan blade is displaced in the height direction, thereby increasing the reverse thrust of the fan blade on the hanging basket during rotation; the transmission assembly can drive the shell to rotate when the distance between the hanging basket and the wall surface changes, and can also convert the rotation of the shell into the movement of the hanging basket. When the hanging basket is far away from the wall surface, the transmission assembly drives the shell to rotate away from the wall surface, the fan blade blows air towards the outside and the lower part, and the hanging basket is pushed to be close to the wall surface. At this time, the rotation point of the shell is higher than that of the fan blade, the downward component force is larger, an additional moment is formed, and the stability effect is enhanced. Similarly, when the hanging basket is close to the wall surface, the reverse thrust and the additional moment jointly push the hanging basket to be far away from the wall surface. Therefore, a small fan wind power can generate sufficient stability force, and the demand for fan power is reduced.

Description

Technical Field

[0001] This invention relates to the field of high-altitude work equipment, and in particular to a construction auxiliary device for exterior wall decorative curtain wall structures. Background Technology

[0002] The suspended platform used for high-altitude operations is a type of high-altitude work equipment consisting of a suspension mechanism, a suspended platform, a hoist, a safety lock, and an electrical control system. It is mainly used for exterior wall decoration, insulation layer construction, curtain wall installation, as well as exterior wall cleaning and maintenance of high-rise buildings. It can safely and conveniently transport construction personnel and required materials to the designated height, greatly reducing the limitations of traditional scaffolding operations and improving the efficiency of high-altitude operations.

[0003] In the prior art, such as Chinese patent application CN114420331A, a suspended platform for high-altitude operations in a nuclear power plant containment vessel and its wind-resistant method are disclosed. The platform includes a suspended platform and a fan. The fan is installed on the first side of the platform facing away from the containment vessel wall, preferably two fans installed symmetrically. The force generated when the fan is turned on can push the suspended platform against the containment vessel wall.

[0004] However, in existing technologies, including the aforementioned patents, when workers are performing construction work on the suspended platform, their actions or external forces may push the platform away from or bring it closer to the wall. To prevent the platform from swaying due to external forces and to ensure smooth construction and personnel safety, it is often necessary to generate a large airflow from the fan. However, excessive airflow consumes more energy, increasing construction costs; at the same time, excessive airflow acting on the suspended platform may cause uncontrollable vibrations, interfering with the delicate operations and reducing construction quality. Summary of the Invention

[0005] Therefore, it is necessary to provide a construction auxiliary device for exterior wall decorative curtain wall structures, addressing the problems of the current construction auxiliary equipment requiring a large airflow for stabilizing the suspended platform.

[0006] The above objectives are achieved through the following technical solutions:

[0007] A construction auxiliary device for an exterior wall decorative curtain wall structure, comprising:

[0008] Hanging basket.

[0009] A fan assembly includes a mounting frame, a housing, and fan blades. The mounting frame is fixedly mounted on the lower wall of the suspended platform. The housing is rotatably connected to the mounting frame. The fan blades are coaxially rotatably connected to the housing. When the fan blades rotate, they can generate a counter-thrust force on the suspended platform. The housing can slide relative to the mounting frame, thereby increasing the counter-thrust force on the suspended platform when the fan blades rotate.

[0010] The transmission assembly is capable of driving the housing and the fixed frame to rotate relative to each other when the distance between the suspended basket and the wall changes, and when the housing and the fixed frame rotate relative to each other, the housing and the fixed frame slide relative to each other; the transmission assembly is also capable of converting the rotation of the housing into the movement of the suspended basket.

[0011] Furthermore, the fan assembly also includes a rotating shaft, and the housing has a sliding groove extending along an axis perpendicular to the rotating shaft. The rotating shaft is provided with a round rod segment and a square rod segment, which are coaxially and fixedly connected. The round rod segment is rotatably connected to the fixed frame, and the square rod segment is embedded in the sliding groove and slidably connected to the housing. The square rod segment is used to enable the housing to rotate synchronously with the rotating shaft. The transmission assembly includes a drive structure that can drive the rotating shaft to rotate when the distance between the suspended platform and the wall changes.

[0012] Furthermore, the transmission assembly also includes a movable frame that is slidably connected to the suspended platform. The movable frame is always in contact with the wall, and the suspended platform moves relative to the movable frame when the distance between the suspended platform and the wall changes.

[0013] Furthermore, the drive structure includes a gear and a rack, the gear being coaxially and fixedly connected to the rotating shaft; the rack is fixedly mounted on the movable frame, and the rack meshes with the gear. When the basket and the movable frame move relative to each other, the rack drives the gear to rotate.

[0014] Furthermore, a first elastic element is provided between the movable frame and the suspended basket. One end of the first elastic element is fixedly connected to the side wall of the movable frame facing the suspended basket, and the other end of the first elastic element is fixedly connected to the corresponding side wall of the suspended basket facing the movable frame. The elastic force of the first elastic element always causes the movable frame and the suspended basket to move away from each other or has a tendency to move away from each other.

[0015] Furthermore, a first sliding rod is provided between the movable frame and the suspended basket. The first sliding rod extends along the width direction of the suspended basket and is used to provide a stable guiding foundation for the relative sliding of the suspended basket and the movable frame.

[0016] Furthermore, the movable frame is rotatably provided with support wheels, the two ends of which are rotatably connected to the end of the movable frame near the wall, and the axis of the support wheels is parallel to the length direction of the suspended basket, and the movable frame abuts against the wall through the support wheels.

[0017] Furthermore, a second sliding rod is provided in the sliding groove. The axis of the second sliding rod is consistent with the extension direction of the sliding groove. The two ends of the second sliding rod are respectively fixedly connected to the housing. The second sliding rod passes through the rotating shaft, and the rotating shaft slides relative to the housing perpendicular to the second sliding rod.

[0018] Furthermore, a second elastic element and a third elastic element are respectively provided between the two side walls of the rotating shaft and the housing. One end of the second elastic element is fixedly connected to the housing, and the other end of the second elastic element is fixedly connected to the rotating shaft. One end of the third elastic element is fixedly connected to the housing, and the other end of the third elastic element is fixedly connected to the rotating shaft. The elastic force of the second elastic element and the third elastic element always keeps the rotating shaft in the middle position of the sliding groove.

[0019] Furthermore, both the fan assembly and the transmission assembly are configured in multiple groups, with the multiple groups of fan assemblies and the multiple groups of transmission assemblies spaced apart along the length direction of the suspended basket.

[0020] The beneficial effects of this invention are:

[0021] This invention provides a construction auxiliary device for exterior wall decorative curtain wall structures, including a fan assembly and a transmission assembly. The fan assembly includes a fixed frame, a housing, and fan blades. The housing can slide relative to the fixed frame, allowing the rotation point of the housing and the rotation point of the fan blades to be relatively displaced in the height direction of the suspended platform, thereby increasing the counter-thrust force on the suspended platform when the fan blades rotate. When the distance between the suspended platform and the wall changes, the transmission assembly can drive the housing to rotate relative to the fixed frame. During the relative rotation of the housing and the fixed frame, the housing slides relative to the fixed frame. Simultaneously, the transmission assembly can also convert the rotation of the housing into the movement of the suspended platform.

[0022] When the suspended platform moves away from the wall, the transmission assembly drives the housing to turn away from the wall, causing the fan blades to blow air outwards and downwards. At this time, the counter-thrust generated by the fan blades will bring the suspended platform closer to the wall. Simultaneously, after the housing and the fixing frame slide relative to each other, the rotation point of the housing is higher than the rotation point of the fan blades. In the counter-thrust generated by the fan blades, the component below the rotation point of the housing is greater than the component above the rotation point of the housing, forming an additional torque that makes the housing rotate. This torque further pushes the suspended platform closer to the wall through the transmission assembly.

[0023] When the suspended platform approaches the wall, the transmission assembly drives the housing to turn towards the wall, causing the fan blades to blow air inward and downward. The resulting thrust from the fan blades propels the suspended platform away from the wall. Similarly, after the housing slides relative to the mounting frame, the housing's rotation point is higher than the fan blades' rotation point. The component of the thrust generated by the fan blades below the housing's rotation point is greater than the component above it, creating an additional torque that rotates the housing. This torque, through the transmission assembly, further propels the suspended platform away from the wall.

[0024] As a result, the counter-thrust generated by the rotation of the fan blades is unevenly distributed above and below the rotation point of the casing, forming an additional torque, which significantly improves the counter-thrust effect of the fan assembly. Only a small amount of fan blade wind force is needed to generate sufficient stabilizing force, reducing the demand for fan power. Attached Figure Description

[0045] The following reference Figures 1 to 13 This invention describes the construction auxiliary equipment for exterior wall decoration curtain wall structures provided in embodiments of the present invention.

[0046] Specifically, the construction auxiliary equipment for the exterior wall decoration curtain wall structure includes a suspension mechanism (not shown in the figure), a drive device, a suspended platform 110, a fan assembly 200, and a transmission assembly 300.

[0047] As a basic support component, the suspension mechanism is usually fixed to the top of the building or a pre-set load-bearing structure. It is connected to the suspended platform 110 by steel cables or chains, providing stable suspension support for the suspended platform 110. In high-altitude work areas, it ensures that the suspended platform 110 can carry construction personnel and tools to achieve smooth vertical lifting and moving, meeting the construction needs of curtain walls of different heights.

[0048] The suspended platform 110 has a rectangular structure, which is used for construction workers to stand and operate. Its top is connected to the suspension mechanism, which can move vertically.

[0049] The fan assembly 200 includes a mounting bracket 210, a housing 220, fan blades 230, and a rotating shaft 240.

[0050] The fixed frame 210 is fixedly mounted on the lower wall of the suspended platform 110. The housing 220 is connected to the fixed frame 210 via a rotating shaft 240. A sliding groove 221 extends from the housing 220 perpendicular to the axis of the rotating shaft 240. The housing 220 serves as the mounting carrier for the fan blade 230. The fan blade 230 is rotatably mounted within the housing 220. The counterforce generated by the rotation of the fan blade 230 keeps the suspended platform 110 at a preset distance from the wall, thereby enhancing the stability of the suspended platform 110 during high-altitude operations. The rotating shaft 240 has a round rod section and a square rod section, which are coaxially fixedly connected. The round rod section is rotatably connected to the fixed frame 210, while the square rod section is slidably mounted within the sliding groove 221. Thus, the housing 220 can rotate synchronously with the rotating shaft 240 relative to the fixed frame 210, and simultaneously, the housing 220 can slide relative to the fixed frame 210, thereby achieving relative displacement between the rotation point of the housing 220 and the rotation point of the fan blade 230 in the height direction of the suspended platform 110.

[0051] The drive unit is used to provide power to the suspension mechanism and fan assembly 200.

[0052] The transmission assembly 300 includes a movable frame 310 and a drive structure. The movable frame 310 is slidably connected to the suspended basket 110 and can always abut against the wall. The drive structure includes a rack 320 and a gear 330. The rack 320 is fixedly mounted on the movable frame 310, and the gear 330 is fixedly mounted on the rotating shaft 240. The rack 320 and the gear 330 mesh with each other.

[0053] During use, when the suspended platform 110 slides relative to the movable frame 310 in a direction away from the wall due to factors such as construction work or wind, the suspended platform 110 will drive the gear 330 to move on the rack 320. Under the meshing action of the rack 320, the gear 330 will rotate counterclockwise, which in turn drives the housing 220 to deflect through the rotating shaft 240, causing the fan blades 230 to blow air outward and downward. At this time, the counter-thrust force generated by the fan blades 230 will make the suspended platform 110 closer to the wall.

[0054] Meanwhile, the deflected housing 220 will slide relative to the fixed frame 210 under the action of gravity. At this time, in the height direction of the basket 110, the rotation point of the housing 220 will be higher than the rotation point of the fan blade 230. This makes the component of the thrust generated by the fan blade 230 below the rotation point of the housing 220 greater than the component above the rotation point of the housing 220, forming an additional torque that makes the housing 220 rotate clockwise around the rotation axis 240. This torque makes the gear 330 have a clockwise rotation tendency relative to the rack 320, thereby enhancing the tendency to push the basket 110 closer to the wall.

[0055] Conversely, when the suspended platform 110 slides relative to the movable frame 310 towards the wall due to factors such as worker construction or wind, the gear 330 will rotate clockwise under the meshing action of the rack 320, causing the fan blades 230 to blow air inward and downward. At this time, the counter-thrust generated by the fan blades 230 will move the suspended platform 110 away from the wall. At the same time, in the height direction of the suspended platform 110, the rotation point of the deflected shell 220 will be higher than the rotation point of the fan blades 230. At this time, in the counter-thrust generated by the fan blades 230, the component below the rotation point of the shell 220 is greater than the component above the rotation point of the shell 220, forming an additional torque that causes the shell 220 to rotate counterclockwise around the rotation axis 240. This torque makes the gear 330 tend to rotate counterclockwise relative to the rack 320, thereby further enhancing the tendency to push the suspended platform 110 away from the wall.

[0056] Therefore, by creating a positional difference between the rotation point of the housing 220 and the rotation point of the fan blade 230, the counter-thrust generated by the rotation of the fan blade 230 is unevenly distributed above and below the rotation point of the housing 220, forming an additional torque, thereby significantly improving the counter-thrust effect of the fan assembly 200. Only a small fan blade 230 wind force is needed to generate sufficient stabilizing force, reducing the demand for fan power, and at the same time enhancing the anti-interference capability of the basket 110.

[0057] Meanwhile, the movable frame 310 is always in contact with the wall as a reference for the change in spacing. The displacement of the basket 110 is converted into the rotation of the shell 220 through the meshing of the rack 320 and the gear 330, realizing the real-time response to the change in the spacing between the basket 110 and the wall, and automatically adjusting the direction of the force of the fan assembly 200.

[0058] In one embodiment, a first elastic member 311 is provided between the movable frame 310 and the suspended basket 110. One end of the first elastic member 311 is fixedly connected to the side wall of the movable frame 310 facing the suspended basket 110, and the other end is fixedly connected to the corresponding side wall of the suspended basket 110 facing the movable frame 310.

[0059] The elastic force of the first elastic element 311 causes the movable frame 310 and the suspended basket 110 to always tend to move away from each other, so as to ensure that when the relative position of the suspended basket 110 and the movable frame 310 changes, the first elastic element 311 can make the movable frame 310 fit tightly against the wall, providing a stable meshing reference for the rack 320 and gear 330 of the transmission assembly 300.

[0060] Because the elastic force of the first elastic element 311 pushes the movable frame 310 against the wall, it also generates a reverse thrust on the suspended platform 110 through the movable frame 310. Therefore, when the suspended platform 110 is in the preset working position, a specific angle is formed between the housing 220 and the suspended platform 110, so that the reverse thrust generated by the rotation of the fan blade 230 is balanced with the elastic force of the first elastic element 311, and the suspended platform 110 is stabilized in the preset position.

[0061] As the suspended platform 110 moves away from the wall, the movable frame 310 remains relatively fixed in position because it is always in contact with the wall. At this time, the length of the first elastic element 311 connecting the movable frame 310 and the suspended platform 110 extends, and the resulting elastic force acts on the wall through the movable frame 310, creating continuous pressure to ensure that the movable frame 310 does not move away synchronously with the suspended platform 110, but always remains in contact with the wall. Simultaneously, the movement of the suspended platform 110 causes the gear 330 of the transmission assembly 300 to slide on the rack 320 of the movable frame 310. Through the meshing of the rack 320 and the gear 330, the gear 330 rotates counterclockwise, which in turn causes the housing 220 to deflect via the rotating shaft 240, causing the fan blades 230 to blow air in a direction away from the wall and downwards. The counter-thrust generated by the rotation of the fan blades 230 drives the suspended platform 110 to move closer to the wall.

[0062] As the suspended platform 110 moves closer to the wall, the moving frame 310 is blocked by the wall and cannot move closer. At this time, the first elastic element 311 is further compressed, and the elastic force generated by the compression increases, further enhancing the pressure of the moving frame 310 on the wall, making its fit more stable. During this process, the movement of the suspended platform 110 will drive the gear 330 to slide in the opposite direction on the rack 320. Under the action of the rack 320, the gear 330 will rotate clockwise, driving the housing 220 to deflect in the opposite direction through the rotating shaft 240, so that the air blowing direction of the fan blade 230 is directed inward and downward. The counter-thrust force generated by the rotation of the fan blade 230 will drive the suspended platform 110 to move away from the wall, counteracting the tendency to move closer, so that the suspended platform 110 maintains dynamic balance near the preset distance from the wall.

[0063] Therefore, by setting the first elastic element 311, the moving frame 310 can fit tightly and stably against the wall, ensuring the stable meshing of the rack 320 and gear 330 in the transmission assembly 300. This accurately converts the change in the distance between the hanging basket 110 and the wall into the rotation of the gear 330, which then drives the housing 220 to deflect in a timely and accurate manner through the rotating shaft 240, providing a stable transmission basis for the fan assembly 200 to adjust the direction and magnitude of the force.

[0064] Meanwhile, when an external force pushes the suspended platform 110 close to the wall, the elastic force of the first elastic element 311 can prevent the suspended platform 110 from getting too close to the wall due to a sudden excessive external force, further enhancing the positional stability of the suspended platform 110 during operation.

[0065] Furthermore, a first sliding rod 312 is provided between the movable frame 310 and the suspended basket 110. The first sliding rod 312 is used to provide a stable guiding foundation for the relative sliding of the suspended basket 110 and the movable frame 310.

[0066] One end of the first sliding rod 312 is fixedly connected to the inner wall of the movable frame 310 near the wall, and the other end is fixedly connected to the inner wall of the movable frame 310 away from the wall. The first sliding rod 312 is horizontal, spanning both ends of the movable frame 310 and penetrating the bottom of the suspended basket 110. The suspended basket 110 can move relative to the movable frame 310 along the axial direction of the first sliding rod 312. Thus, the first sliding rod 312 ensures that the relative movement between the suspended basket 110 and the movable frame 310 is always horizontal, avoiding deviation or tilting due to uneven force.

[0067] In one embodiment, a support wheel 313 is rotatably provided on the side of the movable frame 310 near the wall. The support wheel 313 extends along the length of the basket 110 and can rotate freely around its own central axis to reduce frictional loss when the movable frame 310 contacts the wall.

[0068] By using the support wheels 313, the sliding friction between the movable frame 310 and the wall is converted into rolling friction. This ensures that the movable frame 310 always remains in contact with the wall while reducing the resistance during relative movement. This ensures that the movable frame 310 can flexibly adjust its position as the suspended platform 110 moves vertically, preventing jamming due to excessive friction. Simultaneously, the rotation of the support wheels 313 also cushions the impact force when the movable frame 310 contacts the wall, maintaining stability in the contact state.

[0069] In one embodiment, a second sliding rod 222 is provided in the sliding groove 221 of the housing 220. The axis of the second sliding rod 222 is consistent with the extension direction of the sliding groove 221. Both ends are fixedly connected to the housing 220 and pass through the square rod section of the rotating shaft 240 as a whole, forming a sliding fit with the rotating shaft 240. That is, the rotating shaft 240 can slide relative to the housing 220 along the axial direction of the second sliding rod 222.

[0070] When the housing 220 deflects and slides downward under the action of gravity, the rotating shaft 240 will move relative to the housing 220 along the second sliding rod 222 in a direction away from the bottom of the housing 220. During the sliding process of the housing 220, the second sliding rod 222 always restricts the movement direction of the rotating shaft 240 so that it will not deviate from the extension path of the sliding groove 221.

[0071] Thus, the second sliding rod 222 provides precise guidance for the relative sliding of the housing 220 and the rotating shaft 240, reduces the risk of offset during the sliding process of the housing 220, and ensures that the relative sliding of the housing 220 and the rotating shaft 240 is smooth and precise.

[0072] Furthermore, a second elastic element 223 and a third elastic element 224 are respectively provided between the two side walls of the rotating shaft 240 and the housing 220. One end of the second elastic element 223 is fixedly connected to the side wall of the rotating shaft 240 facing the sliding groove 221, and the other end is fixedly connected to the inner wall of the corresponding side of the housing 220; the third elastic element 224 is symmetrically arranged on the other side of the rotating shaft 240, with one end fixed to the side wall of the rotating shaft 240 and the other end fixed to the inner wall of the other side of the housing 220. The elastic force of the second elastic element 223 and the third elastic element 224 always keeps the rotating shaft 240 in the middle position of the sliding groove 221.

[0073] During use, when the suspended platform 110 slides relative to the movable frame 310 in a direction away from the wall, the deflected housing 220 will slide relative to the fixed frame 210 under the action of gravity, that is, the rotating shaft 240 moves to one side of the third elastic member 224. In the height direction of the suspended platform 110, the second elastic member 223 is lower than the third elastic member 224, so the third elastic member 224 is compressed and the second elastic member 223 is stretched. The compressed third elastic member 224 generates an outward thrust, and the stretched second elastic member 223 generates an inward pull, causing the rotating shaft 240 to return to the middle position of the sliding groove 221. When the housing 220 rotates back to the initial position, under the elastic force of the second elastic member 223 and the third elastic member 224, the rotating shaft 240 will automatically return to the middle position of the sliding groove 221.

[0074] Conversely, when the suspended platform 110 slides relative to the movable frame 310 towards the wall, the rotating shaft 240 moves towards one side of the second elastic member 223. In the height direction of the suspended platform 110, the second elastic member 223 is higher than the third elastic member 224; therefore, the second elastic member 223 is compressed, and the third elastic member 224 is stretched. The compressed second elastic member 223 generates an outward thrust, and the stretched third elastic member 224 generates an inward pull, causing the rotating shaft 240 to return to the middle position of the sliding groove 221. When the housing 220 rotates back to its initial position, under the elastic force of the second elastic member 223 and the third elastic member 224, the rotating shaft 240 automatically returns to the middle position of the sliding groove 221. Thus, the symmetrical elastic constraints of the second elastic member 223 and the third elastic member 224 provide the rotating shaft 240 with a reset capability.

[0075] In one embodiment, the fan assembly 200 and the transmission assembly 300 are both configured as multiple groups, with each group of fan assembly 200 and transmission assembly 300 corresponding to and linked together, and are jointly installed on the suspended platform 110.

[0076] During use, when different parts of the suspended basket 110 experience localized swaying due to uneven wind distribution, the corresponding transmission component 300 will first sense the change in the distance between that part and the wall. The change in the distance between the suspended basket 110 and the wall will cause the rack 320 and gear 330 to mesh and rotate, thereby driving the housing 220 of the corresponding fan component 200 to deflect, causing the fan blades 230 to adjust the blowing direction accordingly.

[0077] Setting up multiple sets of fan assemblies 200 and transmission assemblies 300 enables the corresponding fan assemblies 200 to respond precisely to changes in the spacing of each area of ​​the suspended platform 110, achieving all-round stability of the single suspended platform 110 from the whole to the parts, significantly improving the precision of the control of the suspended platform 110, and enabling the suspended platform 110 to remain stable in complex wind environments.

[0078] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
