[0036] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0037] like Figures 1 to 3 As shown, the utility model provides a horizontal protection device in an elevator shaft, comprising a beam end support 1, a horizontal protection assembly 2 and a wall end support 3;

[0038] One end of the horizontal protection component 2 is connected to the beam end support 1, and the other end of the horizontal protection component 2 is connected to the wall end support 3;

[0039] The protective scaffolding board 4 is arranged on the horizontal protective assembly 2;

[0040] The height of one end of the horizontal protection component 2 is higher than the height of the other end of the horizontal protection component 2;

[0041] The horizontal protection assembly 2 includes a horizontal protection rod 201, a movable pressure plate 202 and a fastener 203;

[0042] One end of the horizontal protection bar 201 is connected to the beam end support 1, and the other end of the horizontal protection bar 201 is connected to the wall end support 3;

[0043] One end of the fastener 203 passes through the movable pressing plate 202 and is connected to the horizontal protection rod 201;

[0044] A space for accommodating and clamping the protective scaffolding board 4 is formed between the movable pressing plate 202 and the horizontal protective rod 201 .

[0045] In one embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, the left end of the horizontal protection component 2 is connected to the beam end support 1, and the right end of the horizontal protection component 2 is connected to the wall end support 3. The horizontal protection device in the elevator shaft is installed through the beam end support 1 and the wall end support 3. A plurality of protective scaffolding boards 4 are arranged on the horizontal protection component 2. The height of the right end of the horizontal protection component 2 is higher than the height of the left end of the horizontal protection component 2. The left end of the horizontal protection rod 201 is connected to the beam end support 1, and the right end of the horizontal protection rod 201 is connected to the wall end support 3. The lower end of the fastener 203 passes through the movable pressure plate 202 and is connected to the horizontal protection rod 201. A space for accommodating and clamping the protective scaffolding board 4 is formed between the movable pressure plate 202 and the horizontal protection rod 201. The worker inserts the protective scaffolding board 4 under the movable pressure plate 202 to avoid adding fasteners, which is convenient for workers to disassemble and install, improves the utilization rate of each component, reduces costs, and increases installation speed.

[0046] The beam end support 1 fits tightly against the surface of the concrete beam at the side of the elevator shaft due to its own structural characteristics, and no additional anchoring is required. The horizontal protection component 2 is then rotated and extended into the elevator shaft. The beam end support 1 is connected to the rotating horizontal protection component 2 through bolts. The length of the horizontal protection rod 201 is slightly larger than the length of the elevator shaft opening, so that the horizontal protection component 2 is tilted and placed inside the elevator shaft opening. Then, the wall end support 3 is made to fit against the wall surface, and the movable pressure plate 202 in the horizontal protection component 2 is rotated to place the protective scaffolding board on the horizontal protection rod 201. When the movable pressure plate 202 is rotated, the movable pressure plate 202 is pressed against the upper end of the protective scaffolding board 4 to prevent the protective scaffolding board 4 from arbitrarily detaching from the movable pressure plate 202, thereby increasing safety.

[0047] More preferably, the movable pressing plate 202 is provided with a toggle convex pattern 204 .

[0048] In one embodiment of the present invention, Figure 2 , Figure 3 As shown, the movable pressing plate 202 is provided with a shifting convex pattern 204, which is convenient for increasing the friction between the worker's fingers and the shifting convex pattern 204, so that the worker can move the movable pressing plate 202 more quickly and accurately.

[0050] In one embodiment of the present invention, Figure 2 , Figure 3 As shown, the pattern direction of the moving convex pattern 204 is perpendicular to the length direction of the protective scaffolding board 4, which greatly increases the friction between the worker's fingers and the moving convex pattern 204, and improves the operation progress of the worker's moving the movable pressure plate 202 for installation or disassembly.

[0051] More preferably, a limiting plate 301 is provided below the wall end support 3 , and an L-shaped structure is formed between the wall end support 3 and the limiting plate 301 .

[0052] In one embodiment of the present invention, Figure 2 , Figure 3 As shown, a limit plate 301 is provided below the wall end support 3, and an L-shaped structure is formed between the wall end support 3 and the limit plate 301, to ensure that the wall end support 3 will not excessively rotate downward due to its own weight before entering the elevator shaft and pressing against the wall, and will fit the wall normally.

[0053] More preferably, the interior of the horizontal protection bar 201 is configured as a hollow structure.

[0054] In one embodiment of the present invention, Figure 2 , Figure 3As shown, the interior of the horizontal protection rod 201 is configured as a hollow structure, which reduces weight and cost, and is also convenient for workers to carry and use. The hollow structure is more convenient for workers to perform drilling operations.
