Description

Technical Field

[0001] This utility model belongs to the technical field of hoisting auxiliary equipment, specifically relating to a hoisting device for combined curtain wall unit panels. Background Technology

[0002] Composite curtain wall unit panels are an advanced type of building curtain wall. They are prefabricated by combining panels made of two or more different materials, such as glass, metal, and stone. They are widely used in the exterior wall decoration of high-end commercial centers, landmark buildings, public venues, and other buildings with high requirements for aesthetic appeal and functional integration. During installation, hoisting equipment is typically used to provide a fixed storage space for the composite curtain wall unit panels, and, in conjunction with lifting equipment, to ensure that the panels are delivered to their target location.

[0003] In existing technologies, composite curtain wall unit panels usually have a certain weight. When the hoisting device carries the composite curtain wall unit panels to the target position, because the composite curtain wall unit panels are in the storage space of the hoisting device, multiple workers are required to cooperate and use auxiliary tools, such as drag chains and ropes, to move the composite curtain wall out of the storage space and to the installation position. This is time-consuming, labor-intensive, and has low installation efficiency. Utility Model Content

[0004] This utility model provides a hoisting device for composite curtain wall unit panels, which aims to solve the problem of low installation efficiency caused by the inconvenience of the existing hoisting devices for composite curtain wall unit panels in moving the composite curtain wall unit panels outward. To achieve the above objectives, the technical solution adopted by this utility model is: to provide a hoisting device for combined curtain wall unit panels, comprising: The fixed frame has a horizontally through-hole for placing the combined curtain wall unit panels; the top of the fixed frame is provided with a mounting position for connecting lifting equipment. A clamping assembly is provided on the fixed frame and has two clamping parts. Both clamping parts are located in the frame opening and are respectively located on both sides of the combined curtain wall unit panel in the horizontal direction. The two clamping parts are used to clamp and fix the combined curtain wall unit panel together. A push assembly is disposed on the fixed frame and located at one end of the frame opening. The push assembly has a plurality of push adsorption parts that can move along the through direction of the frame opening. The push assembly is used to move the combined curtain wall unit panel out of the frame opening from the other end of the frame opening through the push adsorption parts after the clamping assembly releases its clamping of the combined curtain wall unit panel.

[0005] In one possible implementation, the fixed frame includes: A rectangular frame has a length direction and a width direction; the length direction is horizontal and the width direction is vertical; the frame opening is located within the rectangular frame and its through direction is perpendicular to both the length direction and the width direction. The counterweight base is detachably connected to the bottom of the rectangular frame.

[0006] In one possible implementation, the bottom end of the counterweight base is provided with a connection position for mounting the counterweight block.

[0007] In one possible implementation, the clamping component includes: Two slide rods are provided, both of which are arranged in the receiving cavity of the counterweight base along the length direction and are spaced apart along the through direction of the frame opening; A bidirectional lead screw is disposed in the accommodating cavity along the length direction, and its two ends are rotatably connected to the counterweight base. The bidirectional lead screw has two symmetrical helical portions. The slide is provided in two parts, both of which are located in the receiving cavity and correspond to the two helical parts respectively; each slide is slidably connected to the two slide rods and is helically engaged with the corresponding helical part. Two vertical arms are provided, each mounted on a separate slide. The bottom end of each vertical arm is connected to the corresponding slide, and the top end extends through the elongated opening at the bottom of the rectangular frame into the frame opening. Each vertical arm is fixed with multiple clamping claws, which are spaced apart along the vertical direction. Each clamping claw has a V-shaped notch facing the other vertical arm. The vertical arms and the clamping claws form the clamping portion. The driver is fixed on the counterweight base and is powered by the bidirectional lead screw.

[0008] In one possible implementation, a plurality of raised slide bars are provided on the bottom surface of the frame opening, and each of the raised slide bars is spaced apart along the length direction, and each of the raised slide bars is arranged along the through direction of the frame opening.

[0009] In one possible implementation, the push component includes: A crossbeam is located at one end of the frame opening and is fixedly connected to the rectangular frame; The telescopic structure is provided in multiple ways, and each telescopic structure is distributed in a matrix and fixed on the crossbeam. Each telescopic structure has a telescopic end that can extend into the frame opening along the through direction of the frame opening. The suction cups are provided in multiples, each suction cup is set on each of the telescopic ends, and each suction cup is connected to a negative pressure structure; each suction cup and the corresponding telescopic structure are combined to form the push-adsorption part.

[0010] In one possible implementation, each of the telescopic structures is an electric actuator.

[0011] In one possible implementation, there are multiple mounting positions, each of which is located at the top of the rectangular frame.

[0012] The hoisting device for composite curtain wall unit panels provided in this implementation offers advantages over existing technologies. The frame opening of the fixed frame provides storage space for the composite curtain wall unit panels, and the coordination between the hanging position and the hoisting equipment ensures safe transport of the panels and guarantees their safety during hoisting. The two clamping parts of the clamping assembly clamp and fix the panels from both horizontal sides, forming a double-fixing structure combined with the negative pressure connection of the push-adhesive part. This ensures the panels remain stable during hoisting and movement, preventing displacement due to bumps or turns. The push-adhesive assembly moves through the push-adhesive part, ensuring that the composite curtain wall unit panels are directly pushed out of the frame opening and aligned with the installation position once they reach the target installation location. This eliminates the need for multiple workers to use drag chains, ropes, and other auxiliary tools to remove the panels. Workers only need to simply adjust the alignment of the entire device, eliminating the need for multiple people to work together, significantly reducing the difficulty of installing composite curtain wall unit panels and minimizing manpower. The installation process requires no complex auxiliary operations, and the flexible removal of the composite curtain wall unit panels effectively improves the efficiency of installation.

[0015] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Please refer to the following: Figure 1 and Figure 2 The present invention provides a hoisting device for composite curtain wall unit panels. The hoisting device for composite curtain wall unit panels includes a fixed frame 10, a clamping assembly 20, and a pushing assembly 30. The fixed frame 10 has a horizontally penetrating frame opening 13 for placing the composite curtain wall unit panel 40. The top of the fixed frame 10 has a hanging position 14 for connecting lifting equipment. The clamping assembly 20 is mounted on the fixed frame 10 and has two clamping parts, both located within the frame opening 13 and horizontally positioned on either side of the composite curtain wall unit panel 40. The two clamping parts together clamp and fix the composite curtain wall unit panel 40. The push assembly 30 is mounted on the fixed frame 10 and located at one end of the frame opening 13. The push assembly 30 has multiple push adsorption parts that can move along the through direction of the frame opening 13. After the clamping assembly 20 releases the clamping of the combined curtain wall unit panel, the push assembly 30 can drive the combined curtain wall unit panel to move out of the frame opening 13 from the other end of the frame opening 13 through each push adsorption part.

[0017] During operation, the combined curtain wall unit panel 40 is first placed in the frame opening 13 of the fixed frame 10. The combined curtain wall unit panel 40 is clamped from both horizontal sides by the two clamping parts of the clamping assembly 20, while the pushing and adsorbing parts form a negative pressure connection with the panel. The lifting equipment transports the combined curtain wall unit panel 40 to the target installation position through the hanging position 14 connection device at the top of the fixed frame 10. After reaching the position, the clamping assembly 20 is first controlled to release the clamp, and then the pushing assembly 30 is activated, so that multiple pushing and adsorbing parts move synchronously along the through direction of the frame opening 13, directly pushing the panel out of the frame opening 13 and corresponding to the installation position. The operator only needs to adjust the frame opening 13 to align with the target position by moving the lifting device to complete the positioning. Then, the combined curtain wall unit panel 40 is directly fixedly connected by the connector.

[0018] It should be noted that, see [link / reference] Figure 4 In this embodiment of the present invention, the combined curtain wall unit panel 40 is removed from the frame opening 13 only when it has just left the frame opening 13 or is about to completely leave the frame opening 13.

[0019] The hoisting device for combined curtain wall unit panels provided in this embodiment, compared with the prior art, provides storage space for the combined curtain wall unit panels 40 through the frame opening 13 of the fixed frame 10. The hanging position 14, in coordination with the hoisting equipment, enables safe transport of the panels and ensures the safety of the combined curtain wall unit panels 40 during hoisting. The two clamping parts of the clamping assembly 20 clamp and fix the panels from both horizontal sides, forming a double fixing structure in conjunction with the negative pressure connection of the push-adsorption part. This ensures that the panels remain stable during hoisting and movement, preventing displacement due to bumps or turns. The push-up assembly 30, through the movement of the push-adsorption part, ensures that the combined curtain wall unit panels 40 are directly pushed out of the frame opening 13 and aligned with the installation position after reaching the target installation position. This changes the previous method of requiring multiple workers to use auxiliary tools such as drag chains and ropes to remove the panels. Workers only need to simply move the entire device to adjust the alignment position, eliminating the need for multiple people to work together, significantly reducing the difficulty of installation operations and manpower input. The installation process requires no complex auxiliary operations, and the removal of the combined curtain wall unit panels 40 is flexible, effectively improving the installation efficiency of the combined curtain wall unit panels 40.

[0020] In some embodiments, the aforementioned fixing frame 10 may adopt the following... Figures 1 to 3 The structure shown. See also Figures 1 to 3 The fixed frame 10 includes a rectangular frame 11 and a counterweight base 12. The rectangular frame 11 has a length direction and a width direction. The length direction is horizontal, and the width direction is vertical. The frame opening 13 is located in the rectangular frame 11, and its through direction is perpendicular to both the length direction and the width direction. The counterweight base 12 is detachably connected to the bottom end of the rectangular frame 11.

[0021] The orientation of the rectangular frame 11 and the position of the frame opening 13 provide storage and movement space for the combined curtain wall unit panels 40, ensuring stable placement of the panels within the frame opening 13, smooth entry and exit, and protection from damage. The detachable connection between the counterweight base 12 and the rectangular frame 11 facilitates manufacturing; a bolted connection structure can be used. The counterweight base 12 can adjust the device's center of gravity. When the panel moves outward, causing a change in the overall center of gravity, the bottom counterweight base 12 effectively stabilizes the device, preventing excessive tilting. This stable state eliminates the need for workers to expend extra effort adjusting the device's balance; they can focus solely on aligning the frame opening 13 with the installation position, reducing operational difficulty and preventing installation inaccuracies due to device tilt, thus improving installation efficiency.

[0022] In some embodiments, the counterweight base 12 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The bottom of the counterweight base 12 is provided with a connection position 15 for installing the counterweight block.

[0023] The connection point 15 at the bottom of the counterweight base 12 provides a stable installation foundation for the counterweight block, making counterweight adjustment flexible and operable. By adding, removing, or replacing the counterweight block, it is possible to precisely adapt to the combined curtain wall unit panels 40 of different weights. Regardless of the weight or size of the combined curtain wall unit panel 40, the center of gravity of the device can always be kept at the bottom by adjusting the counterweight, effectively dealing with the change in the center of gravity when the combined curtain wall unit panel 40 moves outward, completely avoiding the problem of excessive tilting of the panel, ensuring the stability and safety of the hoisting process, while reducing the difficulty of operation and labor intensity.

[0024] In this embodiment, the connecting position 15 on the counterweight base 12 can be a vertically arranged long screw. Multiple long screws are provided, evenly distributed along their length, and each long screw is fitted with a locking nut. The corresponding counterweight block can have through holes for the long screws to pass through.

[0025] In some embodiments, the clamping component 20 described above may employ, for example... Figure 1 and Figure 3 The structure shown. See also Figure 1 and Figure 3The clamping assembly 20 includes a slide rod 21, a bidirectional lead screw 22, a slide block 23, a vertical arm 24, a clamping jaw 25, and a driver 26. Two slide rods 21 are provided, each positioned along its length within a cavity in the counterweight base 12 and spaced apart along the through direction of the frame opening 13. The bidirectional lead screw 22 is positioned along its length within the cavity and rotatably connected at both ends to the counterweight base 12; the bidirectional lead screw 22 has two symmetrical helical portions. Two slide blocks 23 are provided, each located within the cavity and corresponding to one of the two helical portions. Each slide block 23 is slidably connected to both slide rods 21 and helically engaged with its corresponding helical portion. Two vertical arms 24 are provided, each mounted on one of the two slide blocks 23. The bottom end of each vertical arm 24 is connected to its corresponding slide block 23, and its top end passes through the elongated opening 16 at the bottom of the rectangular frame 11 and extends into the frame opening 13. Each vertical arm 24 is fixed with multiple clamping claws 25, which are spaced apart along the vertical direction. Each clamping claw 25 has a V-shaped notch facing the other vertical arm 24. The vertical arm 24 and each clamping claw 25 form a clamping part. The driver 26 is fixed on the counterweight base 12 and is powered by the bidirectional lead screw 22.

[0026] During operation, after the actuator 26 starts, it provides power to the bidirectional lead screw 22, causing the lead screw 22 to rotate. Since the slide block 23 is helically engaged with the helical part of the bidirectional lead screw 22, and the slide block 23 is slidably connected to the slide rod 21, the slide rod 21 guides and limits the slide block 23. The rotation of the bidirectional lead screw 22 is converted into relative or opposite movement of the two slide blocks 23 along the slide rod 21. When it is necessary to clamp the combined curtain wall unit panel 40, the actuator 26 drives the bidirectional lead screw 22 to rotate forward, the two slide blocks 23 move relative to each other along the slide rod 21, and then the two vertical arms 24 move closer synchronously. The clamping claws 25 on the vertical arms 24 move accordingly until the V-shaped notches of each clamping claw 25 are tightly fitted with both sides of the combined curtain wall unit panel 40, forming a clamping and fixing mechanism from both horizontal sides and the through direction of the frame opening 13. When it is necessary to release the clamp, the actuator 26 drives the bidirectional lead screw 22 to rotate in the opposite direction, the two slides 23 move in opposite directions, and the vertical arm 24 and the clamping claw 25 disengage from the combined curtain wall unit panel 40.

[0027] It should be noted that the actuator 26 can use an existing, mature motor, and the motor and the bidirectional lead screw 22 are connected via a coupling and a reducer. The V-shaped jaws of the clamping claws 25 can adapt to plates of different thicknesses, improving the versatility and stability of clamping. To facilitate motor operation, a power supply can be provided, which can be integrated inside the counterweight base 12 and electrically connected to the actuator 26 via wiring. A controller module is also provided to ensure control over the start, stop, and forward / reverse rotation of the actuator 26.

[0028] The cooperation between the slide rod 21 and the slide block 23 provides guidance for the movement of the slide block 23, ensuring that the two slide blocks 23 move synchronously and smoothly, thereby ensuring the accuracy of relative or opposite movement, avoiding deviation, and ensuring the clamping effect. The two symmetrical helical parts of the bidirectional lead screw 22 enable the two slide blocks 23 to move synchronously relative to each other or in opposite directions, ensuring that the clamping force of the clamping claws 25 on the panel is evenly distributed on both sides of the panel, preventing deformation or insecure fixing of the combined curtain wall unit panel 40 due to uneven clamping force. Multiple clamping claws 25 spaced vertically at intervals clamp the combined curtain wall unit panel 40 from different height positions, increasing the clamping contact area, improving clamping stability, and preventing the combined curtain wall unit panel 40 from swaying up and down during hoisting. The V-shaped jaws of the clamping claws 25 can adapt to combined curtain wall unit panels 40 of different thicknesses, enhancing the versatility of the device and eliminating the need to replace the clamping claws 25 for combined curtain wall unit panels 40 of different thicknesses. This clamping process is fast and efficient, avoiding the tedious steps of manual clamping, saving operation time, and effectively improving installation efficiency. For information on gripper 25, please refer to [link / reference]. Figure 5 It may include a connecting rod, which is set along the length direction, with one end connected to the vertical arm 24 and the other end provided with a V-shaped bayonet.

[0029] In some embodiments, the rectangular frame 11 may be adopted as follows: Figure 1 and Figure 3 The structure shown. See also Figure 1 and Figure 3 The bottom surface of the frame opening 13 is provided with a plurality of raised slide bars 17, each of which is spaced apart along the length direction and is arranged along the through direction of the frame opening 13.

[0030] The raised sliding strip 17 is made of a wear-resistant and smooth material. Its top end is higher than the bottom surface of the frame opening 13. When the combined curtain wall unit panel 40 is placed inside the frame opening 13, it contacts the top end of the raised sliding strip 17, rather than directly contacting the bottom surface of the frame opening 13. When the combined curtain wall unit panel 40 is placed inside the frame opening 13, the raised sliding strip 17 provides support for the panel, creating a gap between the panel and the bottom surface of the frame opening 13. After the clamping assembly 20 is released, when the pushing assembly 30 moves the panel along the through direction of the frame opening 13, relative sliding occurs between the panel and the raised sliding strip 17. Because the surface of the raised sliding strip 17 is smooth and the contact area is small, it can effectively reduce the friction during panel movement.

[0031] In some embodiments, the aforementioned pushing component 30 may employ, as follows: Figure 2 and Figure 4 The structure shown. See also Figure 2 and Figure 4The pushing assembly 30 includes a crossbeam 31, a telescopic structure 32, and suction cups 33. The crossbeam 31 is located at one end of the frame opening 13 and is fixedly connected to the rectangular frame 11. Multiple telescopic structures 32 are provided, arranged in a matrix, and all are fixed to the crossbeam 31. Each telescopic structure 32 has a telescopic end that can extend into the frame opening 13 along its through-path. Multiple suction cups 33 are provided, each suction cup 33 being disposed on its respective telescopic end, and each suction cup 33 is connected to a negative pressure structure. Each suction cup 33, combined with its corresponding telescopic structure 32, forms the pushing suction section.

[0032] When the combined curtain wall unit panel 40 is fixed within the frame opening 13 by the clamping assembly 20, the telescopic ends of each telescopic structure 32 extend, causing the suction cups 33 to approach the panel surface. The negative pressure structure is activated, creating a strong negative pressure adsorption between the suction cups 33 and the panel surface. When the panel needs to be removed, the clamping assembly 20 releases its clamp, and the telescopic ends of each telescopic structure 32 extend synchronously along the through direction of the frame opening 13. The suction cups 33 then move the panel out of the frame opening 13 until the combined curtain wall unit panel 40 is positioned to fit the installation location. After the panel is in place, workers can securely connect the combined curtain wall unit panel 40 to the building. Once the connection is complete, the negative pressure structure stops working, the suction cups 33 detach from the panel surface, and the telescopic ends of each telescopic structure 32 retract.

[0033] Multiple electric actuators are arranged in a matrix to ensure that the thrust is evenly distributed on the panel surface. Preferably, the suction cup 33 is a vacuum suction cup 33 that is currently used for building curtain wall panels, which has the characteristics of strong adsorption and good sealing performance. Since the outer glass surface of the combined curtain wall unit panel 40 is usually facing outward, the suction cup 33 can be precisely aligned with the outer glass surface. The negative pressure structure can be a small vacuum pump, integrated inside the counterweight base 12, and connected to the suction cup 33 through an air pipe. The power supply of the vacuum pump and the driver 26 share the power supply inside the counterweight base 12, and is also controlled by a controller. Of course, the controller can be a wired controller, which can be directly set on the rectangular frame 11. This electronic control technology is existing technology and will not be described in detail here.

[0034] The crossbeam 31 provides a stable mounting platform for the telescopic structure 32. Multiple telescopic structures 32 arranged in a matrix ensure a uniform distribution of thrust, preventing the combined curtain wall unit panels 40 from tilting or shifting due to uneven force during movement, thus guaranteeing the smoothness and accuracy of the panel movement. The suction cup 33, in conjunction with the negative pressure structure, achieves a firm grip on the combined curtain wall unit panels 40, stably driving their movement during the jacking process and ensuring the reliability of the jacking operation. This method eliminates the cumbersome process of multiple people working together with auxiliary tools to remove panels, saving significant operation time and effectively improving installation efficiency.

[0035] In some embodiments, the telescopic structure 32 may adopt the following... Figure 2 The structure shown. See also Figure 2 Each telescopic structure 32 is an electric push rod.

[0036] After the motor of the electric actuator is started, it drives the suction cup 33 to approach the combined curtain wall unit panel 40 and form an adsorption. Regarding the electric actuator, the power supply can be through the aforementioned power source; this technology is existing and will not be elaborated upon here.

[0037] In some embodiments, the mounting position 14 may be adopted as follows: Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2 There are multiple mounting positions 14, and each mounting position 14 is located at the top of the rectangular frame 11.

[0038] The mounting positions 14 can adopt existing common lifting lug structures, which have sufficient strength and load-bearing capacity to meet the lifting requirements of plates of different weights. The specific structure will not be described in detail here. The even distribution of multiple mounting positions 14 can ensure the force balance of the device during lifting, and improve the stability and safety of the lifting process.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
