Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, and more specifically to a self-lifting unloading platform device for a climbing scaffold of a high-rise building. Background Art

[0002] In the construction of high-rise buildings, unloading platforms and climbing scaffolds are usually used. Unloading platforms are temporary operating platforms set up outside high-rise buildings. Their function is to temporarily store construction materials delivered by tower cranes. For example, when the tower crane lifts the construction materials to a preset height, the construction materials can be quickly transferred and stored in the unloading platform, and then transferred from the unloading platform to the required location in the building, thereby reducing the tower crane's occupancy time. Climbing scaffolds are scaffolds that can be anchored to the outer wall of the building and climb up layer by layer.

[0003] After searching, the document with publication number CN204401999U discloses a climbing scaffold with a unloading platform, including a scaffolding body, a load-bearing frame and a cantilever beam, the load-bearing frame and the cantilever beam are detachably installed on the building, the lower part of the scaffolding body is supported on the load-bearing frame, and a lifting device is connected to the cantilever beam, and the pulling end of the lifting device is connected to the scaffolding body; it also includes an unloading platform and an unloading platform beam connected to each other, the unloading platform beam supports the unloading platform, the unloading platform and / or the unloading platform beam are connected to the scaffolding body, and the unloading platform beam is detachably fixed to the building.

[0004] The above-mentioned public document shows that after the connection point between the unloading platform and the building is dismantled, the platform can be moved up and down on the side wall of the building together with the climbing scaffolding without the assistance of a tower crane; after the climbing scaffolding climbs to a preset height, the unloading platform can be connected and fixed to the building on that floor to realize the function of the unloading platform, thereby improving construction efficiency and reducing construction costs.

[0005] However, in actual use, construction materials are transferred and stored on the unloading platform, and then transferred from the unloading platform to the building. When unloading the construction materials, construction workers need to repeatedly enter and exit the suspended unloading platform to carry them, which is time-consuming and labor-intensive, and the safety of the construction workers is difficult to guarantee.

[0030] The horizontal screw 602 penetrates the fixed block 601 and is threadedly matched with the fixed block 601. The top end of the vertical worm 605 is connected to the output end of the first motor 604. The vertical worm 605 and the first worm wheel 603 are meshed with each other.

[0031] Specifically, the vertical worm 605 drives the first worm wheel 603 to rotate through the first motor 604, and the transverse screw 602 rotates with the first worm wheel 603 and cooperates with the fixed block 601 thread, so that the transverse screw 602 drives the moving seat 300 to move, thereby realizing the transfer of building materials into the building.

[0032] In this embodiment, preferably, the lifting mechanism 700 includes three bidirectional screws 701 rotatably arranged on the inner side of the support platform 400 and distributed in a linear array, a second worm gear 702 fixedly sleeved on the outer wall of the bidirectional screw 701, a screw sleeve 703 threadedly connected to the outer wall at both ends of the bidirectional screw 701 and symmetrically distributed with the second worm gear 702 as the axis, a lifting rod 704 hingedly mounted on the screw sleeve 703 and the bottom of the unloading plate 500, a second motor 705 fixedly mounted on one side of the moving seat 300, a rotating shaft 706 rotatably arranged on the inner side of the moving platform, and a worm sleeve 707 fixedly sleeved on the outer wall of the rotating shaft 706.
