Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically to a special transportation and handling device for ALC floor slabs. Background Technology

[0002] ALC stands for Autoclaved Lightweight Concrete, a type of high-performance autoclaved aerated concrete (ALC). ALC panels are porous concrete slabs (containing treated steel reinforcement) made primarily from fly ash (or silica sand), cement, and lime, cured under high-pressure steam. ALC panels can be used as wall materials or roofing panels, making them a high-performance new building material. However, compared to other materials, ALC panels have relatively lower strength, making them more prone to damage and breakage when subjected to impacts or pressure, resulting in poor impact resistance.

[0003] During the construction of ALC panels, workers typically use self-made special trolleys to transport the panels horizontally over short distances. However, these trolleys can only transport one panel at a time, resulting in extremely low efficiency. Furthermore, the top of the ALC panel cannot be fixed to the trolley. During transportation, workers need to specifically hold the top of the ALC panel to prevent it from shaking or tilting, thus avoiding damage caused by the ALC panel falling to the ground. Utility Model Content

[0004] One advantage of this utility model is that it provides a special transportation and handling device for ALC floor slabs, which can place multiple ALC floor slabs at once by hoisting. It is also equipped with shock-absorbing tires, shock-absorbing placement wheels and a braking mechanism, which can reduce the bumps on the ALC slabs and stop quickly in case of problems to prevent collisions. It is also equipped with a clamping device to fix the ALC slabs vertically to prevent them from tipping over, which greatly reduces the workload of workers.

[0005] To achieve at least one of the above advantages of this utility model, this utility model provides a special transportation and handling device for ALC floor slabs, including a chassis and a walking mechanism mounted on the chassis.

[0023] The first embodiment of this utility model is as follows:

[0024] A special transportation and handling device for ALC floor slabs includes a chassis 1 and a traveling mechanism mounted on the chassis 1. The traveling mechanism includes two front wheels 2 and one rear wheel 3. The two front wheels 2 are pneumatic rubber tires, which have a good shock absorption effect. The rear wheel 3 is a swivel wheel, which plays a steering role.

[0025] The front wheel 2 is equipped with a disc brake device, which is connected to a brake cable. The upper part of the chassis 1 is fixedly installed with a handle 10 and a brake lever 11. The brake lever 11 is connected to the disc brake device through a brake cable. When in use, the worker holds the handle 10 to push the trolley. In case of an emergency, the worker can immediately squeeze the brake to stop the trolley and prevent it from colliding with the ALC floor slab.

[0026] A support mechanism for placing ALC floor slabs is installed on the upper part of the chassis 1. The support mechanism includes three parallel support wheels 6. Vertical plates 4 are rotatably connected to both ends of the support wheels 6. The lower ends of the vertical plates 4 are fixedly installed on both sides of the chassis 1. The vertical plates 4 support the support wheels 6 away from the chassis 1, reducing contact between the ALC floor slabs and the chassis 1 and lowering the risk of impact. Simultaneously, a rubber layer for cushioning is provided on the circumference of the support wheels 6. The ALC floor slabs are vertically placed on the support wheels 6 by hoisting. Several ALC floor slabs are arranged horizontally to prevent ALC floor slabs from being damaged. When the ALC floor slab tilts, a limiting mechanism for fixing the ALC floor slab is installed on the upper part of the chassis 1. The limiting mechanism includes a fixed limiting component and a folding limiting component located on both sides of the chassis 1. The fixed limiting component and the folding limiting component form a support on both sides to prevent the ALC floor slab from tilting. The folding limiting component is equipped with a clamping component that can move laterally. After the ALC floor slab is placed on the trolley, one side is close to the fixed limiting component, while the other side may have a certain distance from the folding limiting component. At this time, the clamping component is used to press against the side of the ALC floor slab to ensure that it remains vertical.

[0027] The fixed limiting component includes a fixed riser 7 fixedly installed on the upper part of one side of the chassis 1, and a horizontally arranged horizontal pipe 8 fixedly installed on the upper part of the fixed riser 7 to form a stable structure. One side of the ALC floor slab is in close contact with the fixed riser 7 and the horizontal pipe 8.

[0028] The folding limiting assembly includes several folding risers 12 hinged to the upper part of the other side of the chassis 1 via a pivot 14. A horizontal pipe 8 is fixedly connected to the upper part of each folding riser 12. A positioning plate 13 is fixedly installed on the upper part of the chassis 1, and a pin 15 is detachably mounted on the positioning plate 13. The positioning plate 13 is connected to the folding risers 12 via the pin 15. The folding risers 12 can rotate, facilitating the loading and unloading of ALC floor slabs. After loading, the folding risers 12 are erected, and then the pins 15 are used to fix the folding risers 12 to the positioning plate 13, completing the fixation.

[0029] A threaded rod 17 is horizontally installed on the folded riser 12. The threaded rod 17 is connected to the folded riser 12 in an engaging manner. A limit plate 16 is installed on the inner end of the threaded rod 17. A rubber pad is provided on the inner side of the limit plate 16. A rotating rod 18 is installed on the outer end of the threaded rod 17. By rotating the rotating rod 18, the limit plate 16 can be moved left and right until the rubber pad is pressed against the ALC floor slab.

[0030] The chassis 1 has a retractable lower telescopic tube 5 inside, and the horizontal tube 8 has a retractable upper telescopic tube 9 inside. The upper telescopic tube 9 and the lower telescopic tube 5 are connected by a fixed vertical tube 7, which can be extended. If the ALC floor slab is relatively long, it can achieve a better stable limiting effect.

[0031] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.
