Description

Technical Field

[0001] This application relates to the field of suspended platform lifting equipment technology, and more specifically, to a suspended platform lifting system for curtain wall construction. Background Technology

[0002] With the widespread application of building curtain walls in modern high-rise buildings, their installation and construction technologies have also continuously developed. Currently, for the installation of building facade curtain wall units, suspended platform lifts are commonly used as personnel operating platforms. Specifically, construction workers stand inside the suspended platform, which can be raised and lowered along the building facade, to perform construction operations such as splicing and fixing curtain wall unit panels (such as glass curtain wall panels, aluminum panels, etc.).

[0003] In the existing curtain wall construction process based on suspended platform elevators, there are two main methods for the transfer and supply of curtain wall unit panels, both of which have obvious limitations: Option 1 is the "personnel and materials shared basket" system, where the curtain wall unit panels to be installed and the operators are placed together on the same working surface of the suspended scaffold. In this mode, the scaffold must simultaneously bear the weight of the operators, construction equipment, and the combined load of multiple curtain wall unit panels. This results in a large overall load on the scaffold, placing higher demands on the power of the supporting hoisting winch and the load-bearing capacity of the cantilever structure, which not only increases equipment costs but also introduces additional safety risks.

[0004] Option two is the "split-unit hoisting" method, where the curtain wall unit panels are vertically transported by being suspended outside the suspended platform using independent hoisting structures (such as additional hoisting ropes or electric hoists). When installation is required, operators inside the suspended platform must lean out or use tools to try to grab and drag the unit panels suspended outside the platform. This process is difficult to execute due to the relative swaying of the platform and unit panels caused by wind, resulting in poor alignment and difficulty in grabbing. Furthermore, the dragging process is highly susceptible to collisions between the unit panels and the building facade, causing material damage or the risk of falling objects. Both the acquisition of the unit panels and subsequent installation work suffer from inconvenience, low efficiency, and compromised safety.

[0005] Furthermore, both of these methods rely heavily on manual handling of the curtain wall unit panels, which requires a significant amount of manpower and increases the instability of the installation process. Summary of the Invention

[0006] In view of this, this application provides a suspended platform lifting system for curtain wall construction to solve the technical problems of high labor consumption, inconvenient operation and low construction efficiency in the existing curtain wall construction process based on suspended platform lifts.

[0007] This application provides a suspended platform lifting system for curtain wall construction, wherein the suspended platform lifting system for curtain wall construction includes: A rope fixing structure and a first winch device are installed on the top of the building, and the first winch device is connected to a first traction rope. A suspended platform, the bottom of which has an inlet and outlet; The second winch device and the second traction rope are arranged inside the basket. The first end of the second traction rope is connected to the basket, and the second end of the second traction rope is connected to the second winch device. The second traction rope is slidably suspended on the rope fixing structure. A sliding guide structure is disposed on the suspended platform; A curtain wall unit panel fixing structure is provided, which can be connected to the first traction rope. The first hoisting device can drive the first traction rope to move the curtain wall unit panel fixing structure carrying the curtain wall unit panel through the inlet and outlet. The curtain wall unit panel fixing structure can be slidably supported on the sliding guide structure and slide along the sliding guide structure to extend out of the basket.

[0008] Furthermore, the sliding guide structure includes a first guide rail, a slider, and a second guide rail. The first guide rail is disposed on the suspended platform, and the slider is slidably mounted on the first guide rail along its length direction. The second guide rail is disposed on the slider, and its length direction is perpendicular to that of the first guide rail. Both ends of the second guide rail extend into the interior and exterior of the suspended platform, respectively. The lower end of the curtain wall unit panel fixing structure is provided with a guide groove, which can slide and limit the second guide rail, so that the curtain wall unit panel fixing structure can be slidably supported on the second guide rail along its length direction.

[0009] Furthermore, the suspended platform includes a support base and a side railing disposed on the support base, the inlet and outlet are disposed on the support base, and the first guide rail is disposed on the side railing.

[0010] Furthermore, the curtain wall unit panel fixing structure includes a fixing plate and a plurality of vacuum suction cups disposed on the fixing plate, the guide groove is located at the lower end of the fixing plate, and a lifting ring is disposed at the upper end of the fixing plate.

[0011] Furthermore, the lower end of the fixed plate is provided with two groove beams, the sliding guide structure includes two parallel and spaced second guide rails, the guide groove is formed on the groove beam, the groove beam has an extended abutment portion extending to one side of the vacuum suction cup of the fixed plate, and a stop strip is provided above the end of the extended abutment portion away from the fixed plate.

[0012] Furthermore, the number of the second winch devices is 2, each of the second winch devices is equipped with a second traction rope, the second winch device includes a motor, a clutch and a drum, the output shaft of the motor is connected to the input end of the clutch, the input end of the clutch is connected to the drum through a connecting shaft, and the second end of the second traction rope is wound around the drum.

[0013] Furthermore, the suspended platform lifting system for curtain wall construction also includes a synchronization mechanism, which includes a synchronization shaft rotatably connected to the suspended platform. A synchronization gear is provided at each end of the synchronization shaft, and an output gear is provided on the connecting shaft. The synchronization gears at both ends of the synchronization shaft mesh with the output gears corresponding to each of the second hoisting devices.

[0014] Furthermore, the rope fixing structure includes a frame, a crossbeam that is vertically mounted on the frame, and a telescopic beam that is laterally telescopically mounted on the crossbeam. One end of the telescopic beam away from the crossbeam extends out of the building body and is provided with a first pulley. The second traction rope is slidably suspended on the first pulley.

[0015] Furthermore, the rope fixing structure also includes a counterweight mechanism disposed on the top of the building, and the end of the crossbeam away from the telescopic beam is vertically connected to the counterweight mechanism.

[0016] Furthermore, an upper extension rod is provided on the crossbeam, and a second pulley is provided at the upper end of the upper extension rod. The rope fixing structure also includes a reinforcing rope, which is pressed against the second pulley. The first end of the reinforcing rope is connected to the end of the crossbeam away from the telescopic beam, and the second end of the reinforcing rope is connected to the end of the telescopic beam away from the crossbeam.

[0017] The beneficial effects of the suspended platform lifting system for curtain wall construction provided by this invention are as follows: Compared to existing technologies, the suspended platform in the suspended platform lifting system for curtain wall construction provided by this invention has an inlet and outlet at its bottom. The first hoisting device can drive the first traction rope to pull the curtain wall unit panel fixing structure carrying the curtain wall unit panels through the inlet and outlet. Therefore, when constructing curtain wall unit panels on a building, the curtain wall unit panel fixing structure carrying the curtain wall unit panels can be lifted by the second traction rope and passed through the inlet and outlet into the interior of the suspended platform. This facilitates the operation of personnel inside the suspended platform to grasp and operate the curtain wall unit panel fixing structure carrying the curtain wall unit panels. Then, the curtain wall unit panel fixing structure can be slidably supported on the sliding guide structure and along the sliding guide structure. The sliding mechanism extends the suspended platform, releasing the curtain wall unit panel fixing structure from the curtain wall unit panel, allowing for convenient installation of the curtain wall unit panel onto the building facade. The entire installation process utilizes a sliding guide structure to provide sliding support for the curtain wall unit panel fixing structure, which also guides and limits the fixing structure. This reduces manpower consumption during curtain wall construction, improving convenience, stability, and efficiency. The suspended platform in this curtain wall construction lifting system does not carry the curtain wall unit panels, ensuring a low load while achieving convenient and safe supply and installation of the curtain wall unit panels.

[0025] See Figures 1 to 8 This application provides a suspended platform lifting system for curtain wall construction, wherein the suspended platform lifting system for curtain wall construction includes: A rope fixing structure and a first winch device 3 are installed on the top of the building 1. The first winch device 3 is connected to a first traction rope 2. The suspended platform 100 has an inlet / outlet 101 at its bottom; The second winch device and the second traction rope 4, the first traction rope 2 and the second traction rope 4 are preferably steel ropes, the second winch device is set inside the basket 100, the first end of the second traction rope 4 is connected to the basket 100, the second end of the second traction rope 4 is connected to the second winch device, and the second traction rope 4 can be slidably hoisted on the rope fixing structure. A sliding guide structure is installed on the suspended platform 100; The curtain wall unit panel fixing structure can be connected to the first traction rope 2. The first hoisting device 3 can drive the first traction rope 2 to move the curtain wall unit panel fixing structure carrying the curtain wall unit panel 28 through the inlet and outlet 101. The curtain wall unit panel fixing structure can be slidably supported on the sliding guide structure and slide along the sliding guide structure to extend out of the basket 100. The curtain wall unit panel 28 is, for example, a glass curtain wall panel, an aluminum panel, etc.

[0026] Since the bottom of the cradle 100 in the cradle-type lifting system for curtain wall construction provided by the present invention has an inlet and outlet 101, the first hoisting device 3 can drive the first traction rope 2 to move the curtain wall unit panel fixing structure carrying the curtain wall unit panel 28 through the inlet and outlet 101. Therefore, when constructing the curtain wall unit panel 28 on the building 1, the curtain wall unit panel fixing structure carrying the curtain wall unit panel 28 can be lifted by the second traction rope 4 and passed through the inlet and outlet 101 into the interior of the cradle 100. This makes it convenient for the operators inside the cradle 100 to grab and operate the curtain wall unit panel fixing structure carrying the curtain wall unit panel 28. Then, the curtain wall unit panel fixing structure can be slidably supported on the sliding guide structure and along the sliding guide structure. After the sliding platform 100 extends and releases the fixing structure of the curtain wall unit panel 28 from the curtain wall unit panel fixing structure, the curtain wall unit panel 28 can be easily installed onto the exterior facade of the building 1. The entire installation process can be supported by the sliding guide structure for sliding support of the curtain wall unit panel fixing structure carrying the curtain wall unit panel 28. The sliding guide structure also has a guiding and limiting effect on the curtain wall unit panel fixing structure, thereby reducing the manpower consumption in curtain wall construction and improving the convenience, stability and efficiency of curtain wall construction. The sliding platform 100 in this sliding platform lifting system for curtain wall construction does not carry the curtain wall unit panel 28, so that the curtain wall unit panel 28 can be conveniently and safely supplied and installed while ensuring a low load.

[0027] According to a specific embodiment of this application, the sliding guide structure includes a first guide rail 5, a slider 6, and a second guide rail 7. The first guide rail 5 is disposed on the suspended basket 100. The slider 6 is slidably mounted on the first guide rail 5 along its length direction. The second guide rail 7 is disposed on the slider 6, and the length direction of the second guide rail 7 is perpendicular to the length direction of the first guide rail 5. For example, if the length direction of the first guide rail 5 is arranged along the length direction of the suspended basket 100, then the second guide rail 7 is arranged along the width direction of the suspended basket 100. The two ends of the length direction of the second guide rail 7 extend into the interior and exterior of the suspended basket 100, respectively. The lower end of the wall unit panel fixing structure is provided with a guide groove 12, which can slide and limit the second guide rail 7 so that the wall unit panel fixing structure can be slidably supported on the second guide rail 7 along the length direction of the second guide rail 7. Since the two ends of the second guide rail 7 extend into the inside and outside of the suspending basket 100 respectively, the wall unit panel fixing structure carrying the wall unit panel 28 can slide the wall unit panel 28 from the inside of the suspending basket 100 along the second guide rail 7 to the outside of the suspending basket 100, so as to facilitate the installation and construction of the wall unit panel 28 outside the suspending basket 100.

[0028] According to a specific embodiment of this application, the suspended platform 100 includes a support base 102 and a side railing 103 disposed on the support base 102.

The guide groove 12 is located at the lower end of the fixing plate 8, and a lifting ring 10 is disposed at the upper end of the fixing plate 8. The first traction rope 2 can be directly tied around the lifting ring 10, or it can be connected to a hook and then hooked onto the lifting ring 10 by the hook.

[0030] According to a preferred embodiment of this application, the lower end of the fixing plate 8 is provided with two channel beams 11, and the sliding guide structure includes two parallel and spaced second guide rails 7. The guide groove 12 is formed on the channel beam 11. The channel beam 11 has an extended abutment extending to one side of the vacuum suction cup 9 of the fixing plate 8. A stop strip 13 is provided above the end of the extended abutment away from the fixing plate 8. The stop strip 13 is made of elastic material such as rubber. If the curtain wall unit panel 28 accidentally detaches from the fixing plate 8, the two extended abutments and the stop strip 13 can provide a certain degree of support and limit the curtain wall unit panel 28, which can prevent the curtain wall unit panel 28 from falling to a certain extent.

[0031] According to one embodiment of this application, the number of second winches is 2, each second winch is equipped with a second traction rope 4, the second winch includes a motor 14, a clutch 15 and a drum 16, the output shaft of the motor 14 is connected to the input end of the clutch 15, the input end of the clutch 15 is connected to the drum 16 through a connecting shaft 17, and the second end of the second traction rope 4 is wound around the drum 16.

[0032] According to a preferred embodiment of this application, the suspended platform lifting system for curtain wall construction further includes a synchronization mechanism. The synchronization mechanism includes a synchronization shaft 31 rotatably connected to the suspended platform 100. A synchronization gear 32 is provided at each end of the synchronization shaft 31, and an output gear 33 is provided on the connecting shaft 17. The synchronization gears 32 at both ends of the synchronization shaft 31 mesh with the output gears 33 corresponding to each of the second winches. When one of the motors 14 fails and stops, the clutch 15 corresponding to the motor 14 can be put into a power disengagement state. Then, through the synchronization gears 32 at both ends of the synchronization shaft 31, the power of the motor 14 that has not failed can be transmitted to the drum 16 corresponding to the motor that failed, ensuring that the two drums 16 can still realize the winding and releasing operation of the second traction rope 4, thereby ensuring the reliability of the lifting of the suspended platform 100.

[0033] According to a specific embodiment of this application, the clutch 15 may be a manually mechanically controlled or electronically controlled clutch 15.

[0034] According to one embodiment of this application, the rope fixing structure includes a frame 29, a crossbeam 30 that is vertically mounted on the frame 29, and a telescopic beam 18 that is horizontally telescopically mounted on the crossbeam 30. One end of the telescopic beam 18 away from the crossbeam 30 extends out of the building body 1 and is provided with a first pulley 19. A second traction rope 4 is slidably suspended on the first pulley 19. Specifically, the crossbeam 30 has a telescopic cavity, and one end of the telescopic beam 18 is telescopically mounted in the telescopic cavity. The crossbeam 30 can be provided with a locking screw (not shown) or other mechanism to lock and fix the telescopic beam 18 to the crossbeam 30. The crossbeam 30 can be vertically mounted on and locked to the frame 29 through a similar structure, which will not be described in detail here.

[0035] In addition, the rope fixing structure also includes a counterweight mechanism set on the top of the building 1. The end of the crossbeam 30 away from the telescopic beam 18 is vertically connected to the counterweight mechanism. The counterweight mechanism may specifically include a counterweight frame 20 and a plurality of counterweight blocks 21 set on the counterweight frame 20. The end of the crossbeam 30 away from the telescopic beam 18 is vertically connected to the counterweight frame 20. Specifically, the crossbeam 30 can be vertically installed and locked to the counterweight frame 20 through a connection method similar to the telescopic cooperation method of the crossbeam 30 and the telescopic beam 18.

[0036] According to one embodiment of this application, an upper extension rod 22 is provided on the crossbeam 30, and a second pulley 23 is provided at the upper end of the upper extension rod 22. The rope fixing structure also includes a reinforcing rope 24 (e.g., a steel rope), which is pressed against the second pulley 23. The first end of the reinforcing rope 24 is connected to the end of the crossbeam 30 away from the telescopic beam 18, and the second end of the reinforcing rope 24 is connected to the end of the telescopic beam 18 away from the crossbeam 30.

[0037] In addition, a guide frame 25 is provided on the top of the building 1, and the first traction rope 2 passes through the third pulley 26 and the fourth pulley 27 on the guide frame 25 to connect to the curtain wall unit panel fixing structure.
