Electric reel hoisting platform

Abstract

This invention relates to an electric reel-type hoisting platform installed at the elevator shaft opening of a building. It comprises a pivot base fixed to the floor structure adjacent to the elevator shaft opening, and a rotating platform pivotally connected to the pivot base via a pivot mechanism. The rotating platform can rotate between a first position and a second position, and can be selectively secured by at least one locking mechanism. In the first position, the rotating platform extends into the elevator shaft and is horizontal, allowing for temporary placement of hoisting construction equipment or components. In the second position, the rotating platform rotates to the shaft opening side and shields the opening, forming a protective structure to prevent personnel or objects from falling. The rotating platform may be equipped with reinforcing ribs, an anti-slip layer, and a buffer damping mechanism to improve load-bearing capacity and operational safety. This invention combines the dual functions of temporary placement of hoisting materials and shaft opening safety protection, effectively reducing construction risks and improving work efficiency.

Claims

1. An electric reel-type hoisting platform for use at an elevator shaft opening in a building, and disposed at the elevator shaft opening location on each floor, comprising: a pivot base fixedly disposed on the structure of the floor adjacent to the elevator shaft opening; a rotating platform, one side of which is pivotally connected to the pivot base via a pivot mechanism, allowing the rotating platform to rotate relative to the elevator shaft opening between a first position and a second position; at least one locking mechanism for selectively fixing the rotating platform to the first position or the second position; wherein... When the rotating platform is in the first position, it extends into the elevator shaft and is generally horizontal, so that construction equipment or components can be temporarily placed on it. When the rotating platform is in the second position, it rotates to one side close to the elevator shaft opening and shields the elevator shaft opening to form a protective structure.

2. The electric reel lifting platform as described in claim 1, wherein the pivot mechanism is a horizontal axis pivot structure, allowing the rotating platform to rotate about a horizontal axis.

3. The electric reel lifting platform as described in claim 1, wherein the rotating platform includes a load-bearing plate and a reinforcing rib structure disposed below it.

4. The electric reel lifting platform as described in claim 1, wherein the locking mechanism includes a pin structure, a snap-fit ​​structure, or an automatic positioning pin.

5. The electric reel lifting platform as described in claim 1, wherein the rotating platform further includes an anti-slip surface layer.

6. The electric reel hoisting platform as described in claim 1, wherein the pivot base includes a steel support member fixed to the side of the floor slab or the wall.

7. The electric reel lifting platform as described in claim 1, wherein the rotating platform is provided with a buffer damping mechanism for controlling its rotation speed.

8. The electric reel hoisting platform as described in claim 1, wherein the dimensions of the rotating platform correspond to the width of the elevator shaft opening, such that it completely obscures the elevator shaft opening in the second position.

9. The electric reel hoisting platform as described in claim 1, wherein the rotating platform is installed at the elevator shaft openings on each floor of the building to facilitate the segmented hoisting of elevator equipment.
