Construction auxiliary equipment for outer wall decoration curtain wall structure

Abstract

The invention relates to the field of high-altitude operation equipment, in particular to 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 fan blades. The shell can slide relative to the fixing frame, so that the shell and the rotating point of the fan blades generate displacement in the height direction, and the reverse thrust of the fan blades to the hanging basket during rotation is increased; the transmission assembly can drive the shell to rotate when the distance between the hanging basket and the wall is changed, and rotation of the shell can be converted into hanging basket movement. When the hanging basket is away from the wall, the transmission assembly enables the shell to rotate away from the wall, the fan blades blow air towards the outer lower portion, and the hanging basket is pushed to be close to the wall. At the moment, the rotating point of the shell is higher than that of the fan blades, the lower component force is larger, additional torque is formed, and the stabilizing effect is enhanced. Similarly, when the hanging basket is close to the wall surface, the reverse thrust and the additional torque jointly push the hanging basket to be away from the wall surface. Therefore, enough stable force can be generated by small fan blade wind power, and the requirement for fan power is lowered.

[0027] The following refers to Figures 1 to 13The application discloses a construction auxiliary equipment for an outer wall decoration curtain wall structure.

[0028] Specifically, the construction auxiliary equipment for the outer wall decoration curtain wall structure comprises a suspension mechanism (not shown in the figure), a driving device, a hanging basket 110, a fan assembly 200 and a transmission assembly 300.

[0029] The suspension mechanism is usually fixed on the top of a building or a preset bearing structure and connected with the hanging basket 110 through a steel cable or a chain to provide stable suspension support for the hanging basket 110, so that the hanging basket 110 can be vertically moved to meet the construction requirements of curtain walls at different heights.

[0030] The hanging basket 110 is in a cuboid structure and used for standing operation of a construction worker, and the top of the hanging basket 110 is connected with the suspension mechanism and can be vertically moved through the suspension mechanism.

[0031] The fan assembly 200 comprises a fixing frame 210, a housing 220, a fan blade 230 and a rotating shaft 240.

[0032] The fixing frame 210 is fixedly arranged on the lower wall of the hanging basket 110, the housing 220 is connected with the fixing frame 210 through the rotating shaft 240, the housing 220 is provided with a sliding groove 221 extending in the direction perpendicular to the axis of the rotating shaft 240, and the housing 220 is the mounting carrier of the fan blade 230; the fan blade 230 is rotatably arranged in the housing 220, and the counter thrust generated when the fan blade 230 rotates can keep the hanging basket 110 and the wall surface at a preset distance, thereby enhancing the stability of the hanging basket 110 during high-altitude operation; the rotating shaft 240 has a round rod section and a square rod section, and the round rod section and the square rod section are fixedly connected coaxially; the round rod section is rotatably connected with the fixing frame 210, and the square rod section is slidably arranged in the sliding groove 221. Therefore, the housing 220 can be synchronously rotated relative to the fixing frame 210 along with the rotating shaft 240, and the housing 220 can also slide relative to the fixing frame 210, so that the rotating point of the housing 220 and the rotating point of the fan blade 230 are relatively displaced in the height direction of the hanging basket 110.

[0033] The driving device is used for providing power for the suspension mechanism and the fan assembly 200.

[0034] The transmission assembly 300 comprises a moving frame 310 and a driving structure, the moving frame 310 is slidably connected with the hanging basket 110 and can always abut against the wall surface, and the driving structure comprises a rack 320 and a gear 330, the rack 320 is fixedly arranged on the moving frame 310, the gear 330 is fixedly arranged on the rotating shaft 240, and the rack 320 and the gear 330 are in meshing engagement.

[0035] In use, when the basket 110 slides relative to the moving frame 310 in a direction away from the wall due to worker construction or wind force, the basket 110 drives the gear 330 to move on the rack 320, and the gear 330 rotates counterclockwise under the meshing action of the rack 320, thereby driving the shell 220 to deflect through the rotating shaft 240, and the fan blade 230 blows outward and downward, and the counterforce generated by the fan blade 230 drives the basket 110 to move close to the wall.

[0036] Meanwhile, the deflected shell 220 slides relative to the fixed frame 210 under the action of gravity, and at this time, in the height direction of the basket 110, the rotation point of the shell 220 is higher than that of the fan blade 230, so that in the counterforce generated by the fan blade 230, the component force below the rotation point of the shell 220 is greater than that above the rotation point, forming an additional torque that drives the shell 220 to rotate clockwise around the rotating shaft 240, and this torque makes the gear 330 have a tendency to rotate clockwise relative to the rack 320, thereby enhancing the tendency of the basket 110 to move close to the wall.

[0037] Conversely, when the basket 110 slides relative to the moving frame 310 in a direction close to the wall due to worker construction or wind force, the gear 330 rotates clockwise under the meshing action of the rack 320, thereby driving the fan blade 230 to blow inward and downward, and the counterforce generated by the fan blade 230 drives the basket 110 to move away from the wall. Meanwhile, in the height direction of the basket 110, the rotation point of the deflected shell 220 is higher than that of the fan blade 230, and at this time, in the counterforce generated by the fan blade 230, the component force below the rotation point of the shell 220 is greater than that above the rotation point, forming an additional torque that drives the shell 220 to rotate counterclockwise around the rotating shaft 240, and this torque makes the gear 330 have a tendency to rotate counterclockwise relative to the rack 320, thereby further enhancing the tendency of the basket 110 to move away from the wall.

[0038] Therefore, by making the rotation point of the shell 220 and the rotation point of the fan blade 230 have a position difference, and the counterforce generated by the rotation of the fan blade 230 being unevenly distributed above and below the rotation point of the shell 220, an additional torque is formed, thereby significantly improving the counterforce effect of the fan assembly 200, and only a small wind force of the fan blade 230 can generate sufficient stable force, reducing the demand for fan power, and enhancing the anti-interference ability of the basket 110.

[0039] Meanwhile, the moving frame 310 always abuts against the wall as a reference for the change in distance, and the displacement of the basket 110 is converted into the rotation of the shell 220 through the meshing action of the rack 320 and the gear 330, thereby realizing real-time response of the distance between the basket 110 and the wall, and automatically adjusting the force direction of the fan assembly 200.

[0040] In one of the embodiments, a first elastic member 311 is arranged between the moving frame 310 and the basket 110, one end of the first elastic member 311 is fixedly connected to a side wall of the moving frame 310 facing the basket 110, and the other end is fixedly connected to a corresponding side wall of the basket 110 facing the moving frame 310.

[0041] The elastic force of the first elastic member 311 makes the moving frame 310 and the basket 110 always have a tendency to move away from each other, so as to ensure that when the relative position of the basket 110 and the moving frame 310 changes, the first elastic member 311 can make the moving frame 310 closely adhere to the wall, thereby providing a stable meshing reference for the rack 320 and the gear 330 of the transmission assembly 300.

[0042] Since the elastic force of the first elastic member 311 pushes the moving frame 310 to adhere to the wall while also generating a reverse pushing force on the basket 110 through the moving frame 310, when the basket 110 is in the preset working position, a specific included angle is formed between the shell 220 and the basket 110, and the reverse pushing force generated by the rotation of the fan blade 230 is balanced with the elastic force of the first elastic member 311, so that the basket 110 is stably positioned at the preset position.

[0043] When the basket 110 moves away from the wall, the moving frame 310 is relatively fixed in position because it always adheres to the wall. At this time, the length of the first elastic member 311 connected between the moving frame 310 and the basket 110 is elongated, and the elastic force generated thereby acts on the wall through the moving frame 310, forming a continuous pressure, so as to ensure that the moving frame 310 does not move away from the wall synchronously with the basket 110, and always adheres to the wall. At the same time, the movement of the basket 110 drives the gear 330 of the transmission assembly 300 to slide on the rack 320 of the moving frame 310, and through the meshing action of the rack 320 and the gear 330, the gear 330 rotates counterclockwise, thereby driving the shell 220 to deflect through the rotating shaft 240, so that the blowing direction of the fan blade 230 is directed to the outer lower side away from the wall. The reverse pushing force generated by the rotation of the fan blade 230 drives the basket 110 to move towards the wall.

[0044] When the basket 110 moves towards the wall, the moving frame 310 is blocked by the wall and cannot continue to move closer, at this time the first elastic member 311 will be further compressed, the elastic force generated by compression increases, further enhances the pressure of the moving frame 310 to the wall, so that it is more stable. In this process, the movement of the basket 110 will drive the gear 330 to slide on the rack 320 in the opposite direction. Under the action of the rack 320, the gear 330 will rotate clockwise, drive the shell 220 to deflect in the opposite direction through the rotating shaft 240, so that the blowing direction of the fan blade 230 is directed downward. The counterforce generated by the rotation of the fan blade 230 will drive the basket 110 to move away from the wall, offsetting the tendency to approach, so that the basket 110 maintains dynamic balance near the preset distance from the wall.

[0045] Thus, by setting the first elastic member 311, the moving frame 310 can closely and stably adhere to the wall, ensuring the stability of the engagement of the rack 320 and the gear 330 in the transmission assembly 300, thereby accurately converting the change in the distance between the basket 110 and the wall into the rotation of the gear 330, and then driving the shell 220 to deflect in time and accurately through the rotating shaft 240, providing a stable transmission basis for adjusting the direction and size of the force of the fan assembly 200.

[0046] At the same time, when there is an external force pushing the basket 110 to approach the wall, the elastic force of the first elastic member 311 can prevent the basket 110 from approaching the wall too much due to the sudden excessive external force, further enhancing the position stability of the basket 110 during operation.

[0047] Further, the first sliding rod 312 is provided between the moving frame 310 and the basket 110, and the first sliding rod 312 is used to provide a stable guide basis for the relative sliding of the basket 110 and the moving frame 310.

[0048] One end of the first sliding rod 312 is fixedly connected to the inner wall of one end of the moving frame 310 close to the wall, and the other end is fixedly connected to the inner wall of one end of the moving frame 310 away from the wall. The first sliding rod 312 is in a horizontal state across the two ends of the moving frame 310, and penetrates the bottom of the basket 110. The basket 110 can move relative to the moving frame 310 along the axial direction of the first sliding rod 312. Thus, the first sliding rod 312 ensures that the relative movement of the basket 110 and the moving frame 310 is always in the horizontal direction, avoiding deviation or inclination due to uneven stress.

[0049] In one embodiment, a support wheel 313 is rotatably arranged on the side of the moving frame 310 close to the wall. The support wheel 313 extends along the length direction of the basket 110, and the support wheel 313 can freely rotate around its central axis to reduce friction loss when the moving frame 310 contacts the wall.

[0050] The sliding friction between the mobile frame 310 and the wall surface is converted into rolling friction by the supporting wheel 313, which reduces the resistance when the mobile frame 310 moves relative to the wall surface while ensuring that the mobile frame 310 always abuts the wall surface. This ensures that the mobile frame 310 can adjust its position flexibly with the vertical movement of the hanging basket 110, avoiding movement jamming caused by excessive friction. At the same time, the rotation of the supporting wheel 313 can also buffer the impact force when the mobile frame 310 contacts the wall surface, maintaining the stability of the abutting state.

[0051] In one embodiment, the sliding groove 221 of the shell 220 is provided with a second sliding rod 222, 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 shell 220, and the whole penetrates the square rod section of the rotating shaft 240, forming a sliding fit with the rotating shaft 240, that is, the rotating shaft 240 can slide relative to the shell 220 along the axial direction of the second sliding rod 222.

[0052] When the shell 220 deflects and slides downward under the action of gravity, the rotating shaft 240 will move relative to the shell 220 along the second sliding rod 222 away from the bottom of the shell 220. During the sliding process of the shell 220, the second sliding rod 222 always limits the movement direction of the rotating shaft 240, so that it does not deviate from the extension path of the sliding groove 221.

[0053] Therefore, the second sliding rod 222 provides precise guidance for the relative sliding of the shell 220 and the rotating shaft 240, reduces the risk of deviation during the sliding process of the shell 220, and ensures smooth and precise relative sliding of the shell 220 and the rotating shaft 240.

[0054] Further, the second elastic member 223 and the third elastic member 224 are respectively arranged between the two side walls of the rotating shaft 240 and the shell 220. One end of the second elastic member 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 shell 220. The third elastic member 224 is symmetrically arranged on the other side of the rotating shaft 240, one end of the third elastic member 224 is fixed to the side wall of the rotating shaft 240, and the other end is fixed to the inner wall of the other side of the shell 220. The elastic force of the second elastic member 223 and the third elastic member 224 always makes the rotating shaft 240 located at the middle position of the sliding groove 221.

[0055] In use, when the basket 110 slides relative to the moving frame 310 in a direction away from the wall, the deflected shell 220 will slide relative to the fixed frame 210 under the action of gravity, i.e. the rotating shaft 240 moves to one side of the third elastic member 224. In the height direction of the basket 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 elongated. The compressed third elastic member 224 generates an outward pushing force, and the elongated second elastic member 223 generates an inward pulling force, prompting the rotating shaft 240 to reset to the middle position of the sliding groove 221. When the shell 220 rotates to the initial position again, the rotating shaft 240 will automatically return to the middle position of the sliding groove 221 under the elastic force of the second elastic member 223 and the third elastic member 224.

[0056] Conversely, when the basket 110 slides relative to the moving frame 310 in a direction close to the wall, the rotating shaft 240 moves to one side of the second elastic member 223. In the height direction of the basket 110, the second elastic member 223 is higher than the third elastic member 224, so the second elastic member 223 is compressed and the third elastic member 224 is elongated. The compressed second elastic member 223 generates an outward pushing force, and the elongated third elastic member 224 generates an inward pulling force, prompting the rotating shaft 240 to reset to the middle position of the sliding groove 221. When the shell 220 rotates to the initial position again, the rotating shaft 240 will automatically return to the middle position of the sliding groove 221 under the elastic force of the second elastic member 223 and the third elastic member 224. Thus, the symmetrical elastic force of the second elastic member 223 and the third elastic member 224 provides the rotating shaft 240 with a reset capability.

[0057] In one embodiment, the fan assembly 200 and the transmission assembly 300 are each provided in multiple groups, each group of fan assemblies 200 and transmission assemblies 300 corresponding to each other and being installed together on the basket 110.

[0058] In use, when local shaking occurs in different parts of the basket 110 due to uneven wind distribution, the transmission assembly 300 in the corresponding area will first sense the change in the distance between the part and the wall, and the change in the distance between the basket 110 and the wall will drive the rack 320 and the gear 330 to mesh and rotate, thereby driving the shell 220 of the corresponding fan assembly 200 to deflect and causing the fan blades 230 to adjust the blowing direction accordingly.

[0059] Providing multiple groups of fan assemblies 200 and transmission assemblies 300 enables the precise response of the corresponding fan assembly 200 to be triggered by the distance change in each area of the basket 110, achieving overall to local stability of a single basket 110, and significantly improving the fine control of the basket 110, so that the basket 110 remains stable in a complex wind environment.

[0060] The above-described embodiments only express several implementation manners of the present application, which are described in a more specific and detailed manner, but cannot be understood as a limitation on the scope of the present application. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
