Detailed Description

In order to make the technical means, innovative features, objectives and functions realized by the present invention easy to understand, the present invention will be further described below.

The embodiments described herein are specific embodiments of the present invention, and are intended to be illustrative of the concepts of the present invention, which are intended to be illustrative and exemplary, and should not be construed as limiting the scope of the embodiments of the present invention. In addition to the embodiments described herein, those skilled in the art will be able to employ other technical solutions which are obvious based on the disclosure of the claims and the specification of the present application, and these technical solutions include technical solutions which make any obvious replacement or modification for the embodiments described herein.

A foldable elevator shaft protection plate is shown in figure 1, and comprises a middle main plate 1 and wing plates 2 symmetrically arranged on two sides of the middle main plate 1, wherein the middle main plate 1 and the wing plates 2 are fixedly connected through hinges 3, the middle main plate 1 and the wing plates 2 respectively comprise a rectangular support frame 4 and a steel plate 5 laid on the rectangular support frame 4, and as can be seen in figure 4, angle steel supports 7 used for abutting against a floor slab at an elevator door opening 6 are arranged on the edges of the middle main plate 1; middle part mainboard 1 is close to elevator door opening 6 and keeps away from the tip of elevator door opening 6 and all is equipped with mainboard rings 8, and pterygoid lamina 2 all is equipped with pterygoid lamina rings 9 on keeping away from middle part mainboard 1's top surface and bottom surface.

The width of the middle main board 1 is smaller than that of the elevator door opening 6, the sum of the widths of the wing plates 2 is larger than that of the middle main board 1 by 100mm, and the lengths of the wing plates 2 are the same as that of the middle main board 1.

Rectangular braced frame 4 is formed by the steel pipe concatenation, and rectangular steel pipe frame is fixed with the steel sheet spot welding, and the elevartor shaft guard plate length and width is 2100~2300mm and 2000~2200mm respectively, and wherein, 1 width on middle part mainboard is 1000~1100mm, and 2 widths of pterygoid lamina are 550~560 mm.

The utility model discloses the elevartor shaft guard plate has the triplex to constitute: the main plate and the two wing plates are wider than the elevator shaft by 100 mm. It can be seen from fig. 2 and 5 that two pterygoid lamina of guard plate are folded on the mainboard, use the rope to crowd more than rings, stand alone and hold the rope in the elevator mouth and another alone slowly pushes away the guard plate in the elevator shaft, make guard plate angle steel card structurally. As can be seen from fig. 6 and 7, standing at the door opening of the elevator shaft, two wing plates are opened and placed on the wall of the elevator shaft, the two wing plates are unfolded and completely separated from the elevator shaft together with a main plate, one end of the main plate is clamped on the lower structure of the elevator shaft, the other end of the main plate leans against the opposite wall (the length of the main plate is 100mm greater than the length of the elevator shaft), and then the two wing plates are opened and placed on the structural wall. Under the combined action of the main board and the wing plate, the elevator shaft horizontal partition plate plays a role in protection.

The elevator shaft guard plate is used to take out the guard plate from the elevator shaft after accomplishing: after the use of the protection plate is completed, as can be seen from fig. 3, the wing plate is folded on the main plate by the draw hook 10, and then the main plate is pulled out of the elevator shaft by using the rope. Specifically, a user stands at the opening of the elevator, hooks the hanging rings on the wing plates and pulls the hanging rings hard, and the two wing plates are folded on the main plate. Then one person stands at the elevator opening to pull the main board lifting ring rope, and the other person lifts the main board lifting ring rope to enable the main board angle steel to be separated from the structure to place the main board on the floor. Simultaneously, the ropes of the two lifting rings on the main plate are pulled inwards to the floor, and the stair protection plate is pulled out of the elevator shaft.

The elevator shaft protection plate is customized according to the sizes in different elevator shafts.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
