Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a lifting and installation device for autoclaved aerated concrete slabs. Background Technology

[0002] Autoclaved aerated concrete (AAC) panels are a lightweight, porous, and environmentally friendly building material made primarily from cement, lime, and silica sand, with the addition of corrosion-resistant steel mesh according to structural design requirements. The mixture is cured under high temperature and pressure using steam. This material boasts advantages such as low density, excellent fire resistance, high fire rating, significant sound insulation, and superior thermal insulation. However, in actual construction, efficiently, accurately, and safely lifting and installing these panels to their designated positions remains a significant challenge on-site.

[0003] In existing technologies and construction techniques, common methods for installing and lifting autoclaved aerated concrete (AAC) slabs include using a scissor lift platform (scissor lift) or pre-setting fixed pulley supports under the floor structure and then using a winch for traction lifting to complete the hoisting and positioning of the slabs.

[0004] However, using a scissor lift for installation places high demands on the workspace due to the size and operational characteristics of the equipment, and the purchase and operating costs are relatively high. While using pulley supports in conjunction with a winch achieves lifting functionality to some extent, this method requires pre-installation and fixation of the supports in the structure, making the construction process cumbersome. Furthermore, when installing panels in different locations, frequent adjustments or reconfigurations of the pulley system are often necessary, resulting in an inflexible and inconvenient overall operation and impacting installation efficiency. Therefore, this utility model proposes a lifting and installation device for autoclaved aerated concrete (AAC) panels to solve the aforementioned problems. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a lifting and installation device for autoclaved aerated concrete (AAC) slabs, comprising: a set of two support base plates 1 symmetrically mounted on the ground to improve overall stability; support legs 2 fixedly connected to both ends of the lower surface of each support base plate 1 to further enhance stability; and adjustable casters 3 on both sides of the middle section of each support base plate 1. Adjustment components for adjusting the height of the casters 3 are connected to the top of each caster 3. When the casters 3 are lowered and in contact with the ground, the entire device can be moved easily; when they are raised, they do not contact the ground, thus preventing movement of the entire device. One end of the upper surface of each support base plate 1 is connected to a climbing frame. 4. The bottom end is welded and fixed, making it easy for operators to climb. The other end of the upper surface of the support base plate 1 is welded and fixed to the bottom end of the support column 5. The support column 5 provides stable support for the climbing frame 4. The top of the climbing frame 4 and the support column 5 are welded and fixed to the lower surface of the support plate 6. A winch 7 is fixedly installed on one side of the climbing frame 4. The winch 7 is electrically connected to the external terminal control equipment. A fixed pulley 8 is installed on the upper surface of the support plate 6. An installation plate 9 is provided on one side of the support base plate 1. A relatively movable clamping plate 10 is provided on the upper surface of the installation plate 9. There are two clamping plates 10. A drive assembly for driving the relative movement of the clamping plates 10 is connected to one side of the clamping plate 10. The four sides of the installation plate 9 are fixedly connected to one end of the nylon belt 11. The other end of the nylon belt 11 is fixedly connected to the lifting ring 12.

[0023] In use, by operating the adjustment component, the casters 3 are lowered and contact the ground, which in turn moves the support base plate 1 and its various components, facilitating use in different positions. Once the preset position is reached, the casters 3 are raised again by adjusting the adjustment component, ensuring the stable contact of the support feet 2 with the ground and guaranteeing the stability of the support base plate 1. First, the autoclaved aerated concrete (AAC) board is threaded through the nylon strap 11 and placed between the two clamping plates 10. The drive component then moves the two clamping plates 10 towards each other to clamp and fix the AAC board. Then... The cable on the winch 7 is wound around and passes through the fixed pulley 8 installed on the support plate 6, and a hook is fixed at the end of the cable away from the winch 7. The hook is adapted to the lifting ring 12, and the hook and the lifting ring 12 are connected. Then, by starting the winch 7, the winch 7 drives the cable to move, the cable drives the hook to move, and the hook lifts the lifting ring 12. Under the connection of the nylon belt 11, the entire autoclaved aerated concrete slab is lifted. At the same time, the operator climbs to the corresponding height on the climbing frame 4 to disassemble the lifted autoclaved aerated concrete slab, which facilitates the subsequent fixed installation of the autoclaved aerated concrete slab.

[0024] Diagonal bracing rods 13 are provided on both sides of the support leg 2. The top of the diagonal bracing rods 13 is fixedly connected to the lower surface of the support base plate 1. The diagonal bracing rods 13 further improve the stability of the support base plate 1, thereby improving the stability of the entire device. The winch 7 is welded and fixed to the climbing frame 4 through the fixing plate 20. The fixing plate 20 fixes the winch 7.

[0025] The adjustment assembly includes a limiting sleeve 14, which is fixedly installed on the upper surface of the support base plate 1. The inner ring surface of the limiting sleeve 14 has an internal thread, and an adjusting rod 15 is threaded onto the inner ring surface of the limiting sleeve 14. The bottom end of the adjusting rod 15 is fixedly connected to the top end of the connecting shaft 16. The bottom end of the connecting shaft 16 is fixedly sleeved on the inner ring surface of the limiting bearing 17, and the outer ring surface of the limiting bearing 17 is fixedly sleeved on the top end of the limiting post 18. The limiting bearing 17 adopts an installation method in which the inner ring rotates and the outer ring is fixed. The bottom end of the limiting post 18 is fixedly connected to the universal wheel 3. The limiting post 18 is slidably sleeved in the limiting groove 19 opened in the support base plate 1. The limiting groove 19 limits the limiting post 18, thereby facilitating the up and down sliding of the limiting post 18.

[0026] When it is necessary to move the support base plate 1 and its components, the adjusting rod 15 is twisted to rotate under the limit of the limiting sleeve 14. Due to the threaded connection between the adjusting rod 15 and the limiting sleeve 14, the adjusting rod 15 will move downward along the axis of the limiting sleeve 14. While the adjusting rod 15 is twisting, it will drive the connecting shaft 16 to rotate on the inner ring surface of the limiting bearing 17. Then, as the adjusting rod 15 moves downward, it will drive the limiting post 18 to move. The limiting post 18 slides downward under the limit of the limiting groove 19, thereby driving the caster 3 to gradually come into contact with the ground. Finally, the caster 3 can drive the support base plate 1 to move. When the preset position is reached, the adjusting rod 15 is twisted in the opposite direction to raise the caster 3, thereby avoiding the movement of the support base plate 1 during use and improving safety.

[0027] The drive assembly includes a threaded rod 23, which is rotatably connected to the mounting plate 9 via a limiting seat 21. A limiting rod 22 is provided opposite the threaded rod 23, and the limiting rod 22 is fixedly connected to the mounting plate 9 via the limiting seat 21. The limiting seat 21 provides limiting support for both the threaded rod 23 and the limiting rod 22. The threaded rod 23 has two threads with opposite directions of rotation. The clamping plate 10 is symmetrically arranged about the upper surface of the mounting plate 9. The threaded rod 23 is threadedly connected to one end of the clamping plate 10, and the other end of the clamping plate 10 is slidably connected to the limiting rod 22.

[0028] To ensure the stability of the autoclaved aerated concrete (AAC) slab during lifting, the threaded rod 23 is twisted. Since the threaded rod 23 and the clamping plate 10 are threaded together, the clamping plate 10 will move. The clamping plate 10 will then move along the axis of the limiting rod 22. Since the threaded rod 23 has two threads with opposite directions, the two clamping plates 10 will move towards each other, clamping and fixing the AAC slab. In addition, the nylon straps 11 that are fixed around the mounting plate 9 will further prevent the AAC slab from overturning during lifting.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
