Description

Technical Field

[0001] This utility model relates to the field of curtain wall construction technology, specifically to a high-altitude vertical transportation device for curtain walls. Background Technology

[0002] In the traditional installation of curtain walls for high-rise buildings, tower cranes or construction elevators are typically used for the vertical transportation of materials when installing unitized curtain walls. However, tower cranes or construction elevators are fixed facilities that lack mobility and portability, resulting in a limited scope of operation and a single application scenario. They may not be able to directly reach the specific location where the curtain wall needs to be installed, often requiring workers to manually carry and install it on-site. However, frequent high-altitude operations not only pose high safety risks but also require extremely high professional skills from the operators. In addition, efficiency drops significantly during inclement weather or nighttime construction, affecting the overall project progress.

[0003] In some projects, traditional hoisting rigs have been used to vertically lift unitized curtain walls. However, hoisting rigs usually need to be firmly fixed to the floor slab using anchoring or other methods, which can damage the floor slab structure. Moreover, existing hoisting rigs are heavy and have poor portability, which cannot meet the needs of moving the curtain wall multiple times and multiple floors during installation.

[0004] Therefore, it is necessary to study a high-altitude vertical transportation device for curtain walls. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a high-altitude vertical transportation device for curtain walls, which can effectively solve the problems of poor portability and damage to the floor structure of existing hoisting devices when vertically hoisting unitized curtain walls.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0015] The front bracket is vertically fixed on the support frame, and its upper end is fixedly connected to the cantilever.

[0016] The tie rods are arranged at an angle from top to bottom and from front to back. The upper end of the tie rod is fixedly connected to the rear end of the cantilever, and the lower end of the tie rod is fixed to the support frame.

[0017] Furthermore, the clamping assembly includes a clamping frame, a clamping screw, and a clamping disc;

[0018] The clamping frame is U-shaped with an opening at the bottom. The rear end of the clamping frame is horizontally fixedly connected to the front end of the support frame. The front end of the clamping frame is horizontally threaded with a clamping screw. The front end of the clamping screw is provided with a rotating handle. The rear end of the clamping screw extends into the clamping frame and is fixed with a clamping disc.

[0019] Furthermore, the counterweight frame is vertically spaced with several counterweight uprights, and several counterweight blocks are arranged through each of the counterweight uprights.

[0020] Furthermore, the support frame, front bracket, and tie rod all include an inner rod, an outer rod, and a limiting pin; the inner rod is slidably fitted into the outer rod, and both the inner rod and the outer rod have several corresponding limiting holes along their length direction; the limiting pin passes through the limiting holes to detachably connect the inner rod to the outer rod.

[0021] Furthermore, the bottom of the base frame and counterweight frame is equipped with multiple sets of casters and multiple sets of lifting outriggers.

[0022] Furthermore, the lifting outrigger includes a lifting rod and a supporting base. The lifting rod is vertically threaded onto the lifting frame, and the lower end of the lifting rod passes through the lifting frame and is fitted with the supporting base.

[0023] Furthermore, a movable pulley is rotatably provided on the hook, and the front end of the sling extends downward and wraps around the movable pulley, then extends upward and is fixed to the front end of the cantilever.

[0024] The beneficial effects of the above technical solution are:

It effectively solves the problems of poor portability and structural damage associated with existing lifting devices for vertically transporting unitized curtain walls. Suitable for curtain wall installation in various complex environments, it broadens the application scope and provides strong support for the construction of modern high-rise buildings.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0034] This embodiment aims to provide a high-altitude vertical transportation device for curtain walls, which is mainly used for vertically hoisting unitized curtain walls. It addresses the problems of poor portability and damage to the floor structure of existing hoisting devices when vertically hoisting unitized curtain walls.

[0035] A type of curtain wall high-altitude vertical transportation device, such as Figures 1 to 3 It includes a lifting frame 1, a cantilever 2, slings 3, hooks 4, and a winch 5.

[0036] The lifting frame 1 has a clamping assembly 6 at its front end for clamping and fixing to the floor slab, and a counterweight frame 7 at its rear end. Specifically, the lifting frame 1 includes a support frame 101, a base frame 102, a front support 103, and a tie rod 104. The support frame 101 is arranged horizontally in the front-to-back direction, with the front-to-back direction referenced... Figure 2 The base frame 102 is vertically bolted to the lower surface of the support frame 101, forming a support base to ensure stable placement of the device. The front bracket 103 is vertically bolted to the support frame 101, and its upper end is bolted to the cantilever 2, so that the cantilever 2 is horizontally fixed to the lifting frame 1.

[0037] The tie rod 104 is arranged at an angle from top to bottom and from front to back. The upper end of the tie rod 104 is fixedly connected to the rear end of the cantilever 2, and the lower end of the tie rod 104 is fixed to the support frame 101, so that the tie rod 104, the support frame 101 and the front bracket 103 form a triangular structure with good stability.

[0038] The clamping assembly 6 is located at the front end of the support frame 101, specifically, as shown in the example below. Figure 6 The clamping assembly 6 includes a clamping frame 601, a clamping screw 602, and a clamping disc 603. The clamping frame 601 is U-shaped with a downward opening. The rear end of the clamping frame 601 is horizontally welded and fixedly connected to the front end of the support frame 101. The front end of the clamping frame 601 is horizontally threaded with the clamping screw 602. The front end of the clamping screw 602 is connected with a rotating handle 604 for manually rotating the clamping screw 602. The rear end of the clamping screw 602 extends into the clamping frame 601 and is fixed with the clamping disc 603. When the clamping screw 602 rotates, the clamping disc 603 can move closer to or away from the rear end of the clamping frame 601 to form a clamping area for clamping and fixing to the edge of the floor slab, providing a stable fixed foundation for the front end of the lifting frame 1.

[0039] The counterweight frame 7 is welded and fixed to the rear end of the support frame 101. The counterweight frame 7 mainly stabilizes the rear end of the lifting frame 1 by setting counterweights, preventing the lifting frame 1 from overturning during the lifting process. Several counterweight uprights 11 are vertically fixed on the counterweight frame 7 at intervals. Several counterweight blocks 12 are arranged through each counterweight upright 11, so that the counterweight blocks 12 can be added or removed as needed. The deployment of the counterweight blocks 12 is convenient and will not be offset or misaligned. In addition, the upper surface of the counterweight block 12 is provided with a boss, and the lower surface is provided with a groove that matches the boss. When the counterweight blocks 12 are evenly stacked on the counterweight frame 7, the boss and the groove fit together, further preventing the counterweight blocks 12 from being offset, misaligned or falling off, improving the regularity and stability of the counterweight block arrangement, and ensuring the safety and stability of the overall structure.

[0040] In the installation of the counterweight frame 7 in the winch 5, such as Figure 5 The cantilever 2 has a fixed pulley 9 rotatably mounted at its front end, and the rear end of the sling 3 is wound around the winch 5, with its front end winding around the fixed pulley 9, extending downwards, and connected to a hook 4. For example... Figure 4 A movable pulley 10 is rotatably mounted on the hook 4. The front end of the sling 3 extends downward and wraps around the movable pulley 10, then extends upward and is fixed to the front end of the cantilever 2, forming the movable pulley 10 mechanism, thereby reducing the force required for lifting.

[0041] Furthermore, such as Figures 1 to 3 The support frame 101, front bracket 103, and pull rod 104 are all telescopic adjustment rods, each including an inner rod 105, an outer rod 106, and a limiting pin 107. The inner rod 105 and outer rod 106 are both square steel structures. The inner rod 105 is slidably fitted into the outer rod 106. Both the inner rod 105 and outer rod 106 have several corresponding limiting holes along their length. The limiting pin 107 passes through the limiting holes to detachably connect the inner rod 105 to the outer rod 106. When the height of the lifting frame 1 needs to be adjusted, the limiting pin 107 can be removed, and then the support frame 101, front bracket 103, and pull rod 104 can be adjusted to the corresponding lengths. Finally, they can be re-fixed using the limiting pin 107, thus adapting to different height requirements of the lifting frame 1.

[0042] Furthermore, the base frame 102 and the counterweight frame 7 are equipped with multiple sets of casters 13 and multiple sets of lifting outriggers 8 at their bottoms, such as... Figure 6The lifting outrigger 8 includes a lifting rod 801 and a supporting base 802. The lifting rod 801 is a threaded rod, vertically threaded onto the lifting frame 1. The lower end of the lifting rod 801 passes through the lifting frame 1 and is fitted with the supporting base 802. By rotating the lifting rod 801, the height can be adjusted, allowing the entire device to be arranged horizontally. The supporting base 802 is disc-shaped, which reduces damage to the floor structure. The casters 13 include swivel casters and swivel brake casters, mainly used to improve mobility. When movement is required, the lifting outrigger 8 can be raised, and after being positioned, the lifting outrigger 8 can be lowered to form a stable supporting foundation.
