Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an auxiliary structure for safe hoisting of panels in curtain wall construction. Background Technology

[0002] In existing technologies, the installation of glass curtain walls in high-rise buildings typically relies on equipment such as tower cranes, suspended platforms, or specialized vacuum lifting devices to lift large curtain wall panels from the ground to the installation location. Common hoisting methods primarily involve fixing the curtain wall panel surface with a negative pressure adsorption device, followed by vertical lifting using a main hook or hoisting rope. This traditional method has several prominent problems in practical applications.

[0003] First, in high-altitude environments, curtain wall panels are highly susceptible to significant swaying or tilting due to wind loads, airflow disturbances, and the elastic deformation of the hoisting ropes. This can lead to collisions between the panels and the building structure or adjacent panels, increasing the risk of edge breakage or installation accuracy deviations. Second, during high-altitude hoisting operations, if the main hoisting rope or hook accidentally becomes loose, breaks, or fails due to fatigue, the lack of an effective multi-level mechanical backup protection mechanism poses a safety hazard of the entire panel falling. Furthermore, existing hoisting auxiliary tools offer relatively weak protection for the edges of curtain wall panels. During hoisting, positioning, and fine-tuning, lateral impacts or collisions can easily cause stress concentration, edge chipping, or surface damage at the panel edges, thereby affecting the overall sealing, durability, and aesthetics of the curtain wall.

[0004] How to solve the above-mentioned technical problems is the challenge facing this invention. Summary of the Invention

[0015] The fall protection unit includes a mechanical compression fall protection structure consisting of a fall protection electric rod and a fall protection compression pad installed on the fall protection base frame.

[0016] Preferably, the guide carriage is provided with a flat and stable frame that slides in cooperation with the telescopic base frame unit, and two sets of stable base wheels are symmetrically arranged on the flat and stable frame.

[0017] Furthermore, the stabilizing guide wheel mechanism includes a first guide wheel assembly disposed on a lifting base, and a second guide wheel assembly disposed on the lifting base that cooperates with the first guide wheel assembly, and the structure of the second guide wheel assembly is consistent with the structure of the first guide wheel assembly; Furthermore, the first guide wheel assembly includes two sets of shock-absorbing telescopic arms, each set of which is equipped with a guide wheel.

The hoisting base is equipped with two opening and closing components for controlling the opening and closing angle of one set of shock-absorbing telescopic arms, and the hoisting base is equipped with an opening and closing linkage component for linking the two opening and closing components.

[0018] Preferably, the two sets of shock-absorbing telescopic arms of the first guide wheel assembly are located at the top and bottom ends of the hoisting base or at the left and right sides of the hoisting base, respectively; the two sets of shock-absorbing telescopic arms of the second guide wheel assembly are located at the top and bottom ends of the hoisting base and / or at the left and right sides of the hoisting base, respectively.

[0020] Furthermore, the curtain wall protection mechanism includes a protective ring plate disposed on the auxiliary frame, a protective frame disposed on the protective ring plate, four sets of protective slides that slide in cooperation with the protective frame, a shock-absorbing and abutting component for one side of the curtain wall disposed at one end of the protective slides, and a protective drive component disposed on the protective ring plate for driving the four sets of protective slides to perform synchronous centripetal / centrifugal motion.

[0021] Furthermore, the protective drive assembly includes four corner linkage frames that are rotatably connected to the protective ring plate, and the four corner linkage frames are located at the four corners of the auxiliary frame. A linkage cross plate is provided between two adjacent corner linkage frames, and a linkage groove is provided on the linkage cross plate. The protective slide is provided with a linkage drive rod that slides with the linkage groove. One of the linkage horizontal plates is provided with a drive frame, the protective ring plate is provided with a drive base, the drive base is provided with a linear actuator that is rotatably connected to the drive base, and the moving end of the linear actuator is rotatably connected to the drive frame.

[0022] The linear actuators are configured as linear drive components such as electric rods, hydraulic rods, and electric cylinders.

[0023] The shock-absorbing and abutting assembly includes an abutting base frame mounted on a protective slide, an abutting base plate on one side of the abutting base frame, and a plurality of abutting spring members disposed between the abutting base plate and the abutting base frame. Alternatively, the shock-absorbing and abutting assembly can also be directly configured as an abutting plate or an abutting adhesive layer.

[0024] This invention constructs a rigid motion guide pair by interlocking the guiding and fixing mechanism on the auxiliary frame with the stabilizing guide wheel mechanism on the hoisting base. Combined with the dual-point design of the first and second hoisting points, it effectively eliminates the rotational torque generated by uneven wind loads at high altitudes, preventing the panels from spinning and swaying violently during lifting and lowering, and greatly reducing the risk of the panels colliding with the building structure or scaffolding.

[0025] This invention employs a synchronous motion assembly consisting of a linkage disc paired with a rotating connecting rod or a linkage gear paired with a linkage rack, utilizing the geometric constraints of a purely mechanical structure to replace traditional manual adjustment. This design ensures that the guide carriages on both sides maintain strict displacement synchronization even under uneven force, fundamentally eliminating mechanism jamming or plate tilting caused by asynchronous lifting, and significantly improving the reliability of the equipment under complex working conditions.

[0026] This invention not only relies on a negative pressure adsorption mechanism for primary load-bearing, but also innovatively uses a protective drive component to link four sets of protective sliding frames to perform centripetal movement of the curtain wall. Protective ring plates form a physical enclosure around the panels, further enhanced by locking units in the fall arrestor assembly. This triple redundancy design ensures that even in extreme situations such as negative pressure failure or rope breakage, the curtain wall panels remain securely locked within the frame, completely eliminating the safety hazard of falling objects from heights.

[0027] This invention utilizes a sleeve spring mounted on a stabilizing guide rod and a contact spring on the hoisting base, in conjunction with a spacing adjustment component, to form an elastic buffer layer with active adjustment capabilities. When the panel is in place or encounters a gust of wind, the system can absorb and dissipate the impact energy through the elastic deformation of the spring, preventing stress concentration at the edges of the brittle curtain wall and effectively protecting the structural integrity of the panel.

[0028] The cooperation between the tensioning and opening components and the tensioning and opening linkage components in this invention allows the stabilizing guide wheel to adjust its opening degree according to the specifications of the track on site. This height-adjustable mechanical structure enables the same device to be adapted to curtain wall panels of various specifications and sizes, reducing the frequency of changing lifting equipment on construction site, significantly shortening the operation cycle of a single panel installation, and reducing overall construction costs.

[0036] See Figures 1 to 6 As shown, a safety hoisting auxiliary structure for curtain wall construction includes an auxiliary frame 100. First hoisting points 110 are symmetrically arranged at the top of the auxiliary frame 100. A hoisting base 200 is arranged on the outer side of the auxiliary frame 100. A negative pressure adsorption mechanism 300 for adsorbing the curtain wall is provided on the hoisting base 200. A second hoisting point 210 is also provided on the hoisting base 200. Through the separate arrangement of the first hoisting point 110 and the second hoisting point 210, independent load-bearing and attitude adjustment of the auxiliary frame 100 and the hoisting base 200 are achieved, ensuring that the hoisting center of gravity remains stable even in complex wind conditions. The auxiliary frame 100 is equipped with a guide and fixing mechanism 400 that cooperates with the hoisting base 200. The hoisting base 200 is equipped with a stabilizing guide wheel mechanism 500 that cooperates with the guide and fixing mechanism 400. The auxiliary frame 100 also includes a curtain wall protection mechanism 600 that cooperates with the curtain wall. The stabilizing guide wheel mechanism 500 rolls within the guide and fixing mechanism 400, converting the linear displacement of the hoisting base 200 into controlled orbital motion, effectively preventing the curtain wall panels from swaying or colliding in complex wind conditions.

[0037] Furthermore, the negative pressure adsorption mechanism 300 includes an adsorption base 310, on which a plurality of negative pressure suction cups 320 are provided, on which a negative pressure component 330 is provided that cooperates with the negative pressure suction cups 320, and on which a central control component 340 is provided that cooperates with the negative pressure component 330.

[0038] The negative pressure component 330 includes a negative pressure generating tank, several negative pressure hoses, and a power supply battery forming a negative pressure driving structure. Alternatively, the central control component 340 is a central control chip. The central control component 340 automatically adjusts the output power of the negative pressure driving structure by monitoring the pressure value inside the negative pressure generating tank in real time, ensuring that the suction cup maintains a constant and safe suction force during high-altitude hoisting.

[0039] Furthermore, the negative pressure adsorption mechanism 300 also includes a spacing adjustment component 350 disposed between the hoisting base 200 and the adsorption frame 310 and cooperating with the vibration damping and guiding mechanism. The hoisting base 200 is provided with a vibration damping component 360 that cooperates with the spacing adjustment component 350. This design allows for fine-tuning of the curtain wall's positioning depth in three-dimensional space by adjusting the spacing after successful adsorption, and filters out minor high-frequency vibrations generated by construction machinery.

[0040] Furthermore, the spacing adjustment component 350 is provided on the adjustment bracket 351 on the hoisting base 200, the adsorption base 310 is provided with an adjustment slide 352 that slides with the adjustment bracket 351, the hoisting base 200 is provided with a spacing adjustment unit 353, the hoisting base 200 is provided with a stabilizing guide groove that cooperates with the adsorption base 310, and the adsorption base 310 is provided with a stabilizing guide rod that cooperates with the stabilizing guide groove; Therefore, the damping component 360 includes a sleeve spring fitted on the stabilizing guide rod, and a plurality of abutment springs are provided on the hoisting base 200. The sleeve spring provides axial restoring balance force, while the abutment springs are used to absorb the impact energy at the moment of contact between the curtain wall and the base, protecting the brittle curtain wall material.

[0042] The adsorption base 310 can be directly fixedly connected to the hoisting base 200, or the spacing adjustment component 350 can be used as the connecting part between the two.

[0043] Furthermore, the guiding and fixing mechanism 400 includes guide frames 410 respectively disposed on both sides of the auxiliary frame 100, and guide slides 420 slidably engaged with the guide frames 410 on both sides of the auxiliary frame 100. Guide slides 420 are disposed on the guide slides 420 and cooperate with the stabilizing guide wheel mechanism 500. The guide slides 420 slide relative to the guide frames 410 to achieve stable guidance and position adjustment of the hoisting base 200 relative to the auxiliary frame 100. The guide slide 430 is provided with a guide groove 440 that cooperates with the stabilizing guide wheel mechanism 500. A limiting block 450 that cooperates with the guide slide 430 is provided at the top of the guide slide 430. The limiting block 450 serves as a protection for the end of the stroke, preventing the guide wheel 512 from accidentally sliding off the track and causing the mechanism to disintegrate.

[0044] The auxiliary frame 100 is equipped with a synchronous motion component 460 for driving the guide slide 420 to move relative to each other, and a fall protection component 470, which works in conjunction with the suspension rope connected to the positioning base, is provided between the two guide frames 410. The synchronous motion component 460 ensures that the tracks on both sides are evenly stressed when the hoisting base 200 is raised and lowered within the frame, avoiding mechanical jamming due to uneven loading.

[0045] Two preferred structural designs for the synchronous motion components 460 are provided, as follows: Firstly, the synchronous motion assembly 460 includes two sets of synchronous drive rods respectively disposed on two sets of guide frames 410, and a synchronous module disposed in the auxiliary frame 100.

[0046] Secondly, the synchronous motion component 460 includes a motion drive unit 461 disposed on one of the guide frames 410, a guide motion unit 462 disposed on the other guide frame 410 that cooperates with the motion drive unit 461, and a motion linkage unit 463 for linking the motion drive unit 461 and the guide motion component is disposed at both the top and bottom ends of the auxiliary frame 100. The motion linkage unit 463 includes a first crossbeam 4631 disposed on one of the guide frames 410, and the first crossbeam 4631 is slidably engaged with the auxiliary frame 100.

The auxiliary frame 100 is provided with a linkage module 4633 that cooperates with the first crossbeam 4631 or the second crossbeam 4632.

[0047] In summary, the synchronous motion component 460 ensures that the guide slides 420 on both sides extend, retract, or rise and fall synchronously through mechanical linkage or drive linkage, avoiding unilateral lag that could cause the hoisting base 200 to twist or tilt, thereby improving the overall hoisting stability.

[0048] The motion drive unit 461 can be configured as a linear drive component such as an electric rod, a hydraulic rod, or a moving lead screw; or, the motion drive unit 461 can be configured as a linear transmission structure composed of a chain, a sprocket, and a motion motor. The guide motion unit 462 includes a plurality of guide cylinders disposed on the guide frame 410, and correspondingly, the guide slide 420 is provided with guide slide rods that cooperate with the guide cylinders; or, the guide motion unit 462 may also be configured as a guide groove, and the guide slide 420 is provided with a motion guide rod that cooperates with the guide groove.

[0049] Two preferred structural designs for the linkage module 4633 are provided, as follows: Firstly, the linkage module 4633 includes a linkage disk disposed in the auxiliary frame 100 and rotatably engaged with the auxiliary frame 100, and two symmetrically arranged rotating connecting rods on the linkage disk; wherein, the two ends of the first crossbeam 4631 and the second crossbeam 4632 are respectively rotatably connected to the linkage disk and the guide frame 410.

[0052] Preferably, the auxiliary frame 100 is provided with a set of slidable wheels that are slidably engaged with the first crossbeam 4631 or the second crossbeam 4632.

[0053] The linkage module 4633 achieves precise synchronous movement between the first crossbeam 4631 and the second crossbeam 4632 through the meshing of the rotating connecting rod or gear rack, reducing mechanical backlash and improving guiding accuracy; the linkage cavity or stable wheel set further reduces sliding friction and vibration, ensuring stability under long-term use.

[0054] Furthermore, the fall arrestor assembly 470 includes telescopic base frame units 471 respectively disposed on the guide frame 410. Each telescopic base frame unit 471 is provided with a fall arrestor base frame 472 at one end near the other telescopic base frame unit 471. The fall arrestor base frame 472 is provided with a locking unit 473 that cooperates with the other fall arrestor base frame 472. The fall arrestor base frame 472 is provided with a fall arrestor unit 474, and the fall arrestor base frame 472 is provided with a fall arrestor module.

[0056] The fall protection unit 474 includes a mechanical compression fall protection structure consisting of a fall protection electric rod and a fall protection compression pad installed on the fall protection base frame 472.

[0057] When the main hoisting rope accidentally comes loose or breaks, the anti-fall component 470 quickly closes the two anti-fall base frames 472 on both sides to form a closed loop through the locking unit 473. At the same time, the electric rod of the anti-fall unit 474 pushes the compression pad to clamp the auxiliary hoisting rope, realizing mechanical backup grip, preventing the hoisting base 200 and the entire curtain wall from falling, and providing multi-level safety redundancy.

[0058] Preferably, the guide carriage 420 is provided with a flat and stable frame that slides in cooperation with the telescopic base frame unit 471, and two sets of stable base wheels are symmetrically arranged on the flat and stable frame.

[0059] Furthermore, the stabilizing guide wheel mechanism 500 includes a first guide wheel assembly 510 disposed on the hoisting base 200, and a second guide wheel assembly 540 disposed on the hoisting base 200 to cooperate with the first guide wheel assembly 510, and the structure of the second guide wheel assembly 540 is consistent with the structure of the first guide wheel assembly 510.

Each set of shock-absorbing telescopic arms 511 includes two shock-absorbing telescopic arms 511 symmetrically arranged on the hoisting base 200. The hoisting base 200 is provided with two opening and closing components 520 for controlling the opening and closing angle of a set of shock-absorbing telescopic arms 511. The hoisting base 200 is also provided with an opening and closing linkage component 530 for linking the two opening and closing components 520.

[0060] Preferably, the two sets of shock-absorbing telescopic arms 511 of the first guide wheel assembly 510 are located at the top and bottom ends of the hoisting base 200 or at the left and right sides of the hoisting base 200, respectively; the two sets of shock-absorbing telescopic arms 511 of the second guide wheel assembly 540 are located at the top and bottom ends of the hoisting base 200 and / or at the left and right sides of the hoisting base 200, respectively.

[0061] In this configuration, the guide wheel 512 in the first guide wheel assembly 510 is located on a different operating surface than the guide wheel 512 in the first guide wheel assembly 510. The stabilizing guide wheel mechanism 500 achieves gapless rolling guidance of the hoisting base 200 along the guide path by embedding the guide wheels 512 on multiple sets of shock-absorbing telescopic arms 511 into the guide grooves 440. The arrangement of guide wheels 512 on different operating surfaces forms multi-directional constraints, which significantly suppresses the forward and backward and left and right swaying during the hoisting process and improves the attitude control accuracy.
