[0037] Reference Figures 1 to 7 As shown, the present invention provides an elevator shaft protection device, including: a support assembly 1, a wall-mounted component 2, a top support assembly 3, and a platform plate 4.

[0038] There are multiple support components 1. In this embodiment, there are two support components.

[0039] Specifically, the support assembly 1 includes two opposing crossbeams 11 and multiple longitudinal beams 12. The crossbeams 11 are inclined at an angle of 15° to 20°. The longitudinal beams 12 connect the two crossbeams 11. A first notch is formed at the lower end of each crossbeam 11. The multiple longitudinal beams 12 at the upper end of each crossbeam 11 have through holes arranged along the length of the crossbeam 11. Extension arms 13 are adjusted to pass through these through holes.

[0040] The wall-mounted component 2 is installed on the inner wall A of the elevator shaft facing the elevator door opening. The extension arm 13 is hinged to the wall-mounted component 2.

[0041] The elevator shaft has two opposing inner walls. One inner wall has an elevator door opening, while the other inner wall A has multiple wall-mounted components installed. The multiple wall-mounted components are spaced apart horizontally, and their positions correspond one-to-one with the upper ends of multiple support components.

[0042] The top support assembly 3 includes multiple hook-and-loop members 31 and a connecting beam 32.

[0046] The elevator shaft protection device of the present invention has high strength, large load-bearing capacity, and strong stability: the structural strength of the support components and platform plate is more reliable and the stability is better.

[0047] The length of the support component of the elevator shaft protection device of the present invention is adjustable and is not limited by the size of the elevator shaft and door opening, thus having greater applicability.

[0048] The elevator shaft protection device of the present invention has multiple supporting components installed on the platform plate to form a whole, which has better stability and will not cause dangerous phenomena such as side overturning.

[0049] In this embodiment, the wall-mounted component 2 includes: an inner lining plate 21 and two ear plates 22.

The ear plates 22 have second shaft holes. Both ends of the hinge shaft 131 are rotatably inserted through the second shaft holes of the two ear plates 22 respectively.

[0052] See Figure 4 As shown, a limiting block 132 is fixedly mounted on the upper part of the extension arm 13. The side of the limiting block 132 facing the inner wall A is a sloped side. The sloped side is inclined upward toward the inner side of the elevator shaft. A plurality of second notches a are formed on the sloped side. A locking rod 211 is rotatably mounted on the top of the inner lining plate 21. The locking rod 211 is detachably inserted into a second notch a.

[0053] See figure Figure 1 and Figure 4 As shown, the platform plate 4 includes a fixed plate 41 and a movable plate 42. The fixed plate 41 is laid on the crossbeams 11 of the plurality of support components 1. The movable plate 42 has a first side and a second side opposite to each other. The first side of the movable plate 42 is rotatably connected to the fixed plate 41. The second side of the movable plate 42 is obliquely upward and presses against the inner wall A of the upper part of the inner lining plate 21.

[0054] In this embodiment, the crossbeam 11, the longitudinal beam 12, and the platform plate 4 are each provided with multiple weight-reducing holes.

[0055] Continue reading Figure 2 , Figure 3 and Figure 6 A screw 33 is rotatably connected to the hook-and-wall component 31. The connecting beam 32 has a threaded hole. The screw 33 is screwed into the threaded hole.

[0056] Continue reading Figure 6 As shown, an anti-detachment flange is formed at the end of the reaction shaft 311 away from the hook wall member 31. The anti-detachment flange is attached to the outer side of the crossbeam 11. The anti-detachment flange is arranged in a circle along the circumference of the reaction shaft.

[0057] In this embodiment, the connecting beam is a square tube, and the through hole on the connecting beam is a threaded hole. The end of the extension arm 13 away from the wall attachment 2 has an external thread. One end of the extension arm 13 is screwed into the through hole of the crossbeam 11.

[0058] This invention provides a construction method for an elevator shaft protection device, comprising the following steps:

[0059] S1: Install multiple wall-mounted components 2 on the inner wall A of the elevator shaft facing the elevator door opening.

[0060] In some embodiments, when constructing the infill wall of the elevator shaft, concrete is embedded in the infill wall such that embedded parts (such as steel plates) in the concrete blocks are positioned opposite an elevator door opening. Specifically, the height of the embedded parts is slightly higher than the height of the lower sidewall of the elevator door opening, allowing the subsequent support components to be positioned at an angle.

[0061] S2: Hook multiple wall hooks 31 onto the lower side wall B of the elevator doorway.

[0062] S3: Install the connecting beam 32 on the lower side wall B, and connect multiple hook wall pieces 31 to the connecting beam 32 to form the top support assembly 3, so that the top support assembly 3 corresponds to the position of the wall attachment 2 on the inner wall A.

[0063] S4: The first notches of the two crossbeams 11 of the multiple support components 1 are rotatably fitted onto the reaction shafts 311 on opposite sides of a hook wall component 31.

[0064] S5: Hinge the extension arm 13 of the multiple support components 1 to the wall attachment 2.

[0065] After the extension arm of the support assembly is hinged to the wall mount via the hinge shaft, the locking rod is flipped downward and inserted into a properly positioned second notch to lock the tilt angle of the support assembly while preventing the support assembly from flipping up and down.

[0066] S6: Platform plate 4 is laid on multiple support components 1.

[0067] When laying the platform board, first install the fixed plate of the platform board, and then install the movable plate. The movable plate can be installed on the fixed plate by hinge, so that the movable plate is positioned above the limit block and the wall attachment.

[0068] The fixed panels consist of multiple unit panels spliced ​​together. Each unit panel weighs less than 10kg, greatly reducing the difficulty of handling and the danger of on-site operation for workers. On-site installation of each component is convenient and simple; experimental measurements show that installation takes approximately 3 minutes and disassembly takes approximately 2 minutes, demonstrating high efficiency.

[0069] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
