[0012] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.

[0013] like Figure 1 As shown, the present invention provides a flap-type elevator shaft operating platform, the elevator shaft is surrounded by a shaft wall 1, and an installation hole for an elevator door is reserved on one side of the wall; the operating platform includes a flap 3 and an extension plate 4, the flap 3 is hingedly placed vertically on the bottom plate at the installation hole, the outer side surface of the flap 3 is detachably connected to the wall outside the installation hole, and two symmetrically arranged extension plates 4 are hingedly connected to the outer side surface of the flap 3, and the outer edge of the extension plate 4 is close to the inner wall of the shaft wall 1 after opening; a support structure 2 is fixed to the inner wall of the shaft wall on the opposite side of the installation hole, and the support structure 2 is used to overlap the upper edge of the flap 3.

[0014] In order to ensure that the flap 3 is in a horizontal state after being lowered, the supporting structure 2 can be a supporting plate or a corbel. The supporting plate is horizontally fixed on the inner wall of the shaft wall opposite to the installation hole at the same height as the floor slab, and the top of the flap 3 is overlapped on the supporting plate 2; if it is a corbel, more than two corbels are horizontally evenly distributed on the inner wall of the shaft wall opposite to the installation hole to balance the force.

[0015] In some preferred embodiments, the flap 3 is connected to the extension plate 4 through a damping hinge 6, which ensures that the extension plate 4 will not rotate under the action of non-human external forces, thereby preventing the extension plate from rotating at will and causing safety hazards. The extension plate 4 is connected to the outer wall of the installation hole through a door pin 5 to achieve a detachable connection. The pin hole ring is installed on the outer wall of the wall on one side of the installation hole, and the latch is installed on one side of the outer surface of the extension plate, or the two can be installed in reverse. When the flap 3 is pulled up, the extension plate 4 is opened again, and the latch is inserted into the pin hole ring to temporarily fix the flap 3 to the wall to prevent accidental tipping over, thereby serving as a protective door for the hole. When the side edge of the extension plate 4 is closely adjacent to the floor wall and there is no space for installing the door pin, a magnetic invisible door stopper 7 is installed on the wall to prevent the extension plate 4 from swinging arbitrarily in the upright state.

[0016] like Figure 2 As shown, the extension plate 4 is also provided with a handle or a pull hole 9, and the construction worker holds the handle or the pull hole 9 to lower and pull up the flap. Figure 1 As shown, a pull ring is installed on the upper outer surface of the flap 3, and a rope 8 is connected to the pull ring, and the flap 3 is lowered or pulled up by the rope 8.

[0017] In actual application, the flap is mostly made of 4mm thick steel plate, the height of the flap is the same as the distance from the installation hole to the inner wall of the opposite side of the well wall, the extension plate is made of 2mm thick steel plate, the height of each extension plate is the same as the height of the flap, and each extension plate is connected to the flap through two damping hinges. The bottom of the flap is connected to the floor slab through a hinge.

[0018] The method of using the above-mentioned flap type elevator shaft operating platform is as follows: Stand on the support structure in the shaft wall of the elevator shaft at the bottom layer where the upper floor slab is installed, hinge the flap of the upper floor slab to the installation hole of this layer, open the pin connection structure, and lower the flap by a handle or rope so that the upper edge of the flap overlaps the support structure; Lower the extension plate so that the outer edge of the extension plate fits the inner wall of the shaft wall, forming an operating platform that fully covers the entire elevator shaft and can be used by construction workers to stand. Figure 3 As shown, standing on the operating platform, the operation on this layer and the installation of the upper support structure are performed; Repeat the above steps to complete the flap installation and other elevator shaft construction work layer by layer; When the flap needs to be retracted, first reset the extension plate to be perpendicular to the flap, pull up the flap with a rope or handle, and then pin the flap to temporarily fix it after resetting; After the elevator shaft construction work is completed, the flaps and supporting structures are removed from top to bottom, and the supporting structure of the upper layer is removed standing on the flap of the lower layer.

[0019] Finally, it should be noted that the above are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
