[0029] Embodiment

[0030] Refer to Figures 1-4, this technical solution provides a protective device for the installation of an additional elevator shaft, which includes a main frame 1. A folding mechanism 2 is arranged inside the main frame 1. The folding mechanism 2 includes: a fixed rod 201, a first short board 202, a first long board 204, a first folding board 206 and a movable rod 208. The fixed rod 201 is fixedly connected to the top of the main frame 1. One end of the first short board 202 is movably connected to a second short board 203 through a movable shaft. The first short board 202 and the second short board 203 are movably connected to the fixed rod 201 through the movable shaft. One end of the first long board 204 is movably connected to a second long board 205 through a movable shaft. One side of the first long board 204 and the second long board 205 is movably connected to the first short board 202 and the second short board 203 through a movable shaft. One side of the fixed rod 201 is movably inserted with a first folding board 206. One side of the first folding board 206 is movably connected to a second folding board 207 through an insertion shaft. One side of the movable rod 208 is movably connected to one side of the second folding board 207 through the insertion shaft. Place the main body of the main frame 1 into the elevator shaft, pull the movable rod 208, and the first short board 202, the second short board 203, the first long board 204 and the second long board 205 move in a scissor shape and are stretched under the action of the movable shaft, thereby driving a plurality of first folding boards 206 and second folding boards 207 to change from the folded state to the flattened state, and finally making the folding mechanism 2 longer. Insert the movable rod 208 from the entry slot 101 into the movable slot 102 and set it at different positions in the movable slot 102.

[0031] Refer to Figures 1-4 , based on the same concept as in the above Embodiment 1, this embodiment also proposes that the bottom structural rod rope of the main frame 1 is provided with an entry slot 101 and a movable slot 102. The opening of the entry slot 101 faces upward. The movable slot 102 is transversely grooved and communicates with the entry slot 101.

[0032] Specifically, a limiting mechanism 3 is provided on the front side of the main frame 1. The limiting mechanism 3 includes a double-ring mounting strip 301, which is fixedly connected to one side of the main frame 1 through a connecting frame. The double-ring mounting strip 301 includes two sleeves. A structural rod is fixedly connected between the sleeves of the double-ring mounting strip 301. A telescopic rod 302 is movably sleeved in the sleeve of the double-ring mounting strip 301. A boss limiting groove 3021 is formed on the telescopic rod 302. A wrench 303 is movably connected to the structural rod of the double-ring mounting strip 301 through a movable shaft. The bottom of the wrench 303 is movably connected to a special-shaped plate 3031 whose cross-sectional shape is adapted to that of the boss limiting groove 3021 through an insertion shaft. A limiting rod 304 is provided on the sleeve of the double-ring mounting strip 301. The limiting rod 304 is provided with a limiting rod 304 whose cross-sectional shape is adapted to that of the boss limiting groove 3021. One end of the telescopic rod 302 is fixedly connected to the main frame 1 through a connecting rope. When the wrench 303 is pulled, the special-shaped plate 3031 moves on the side of the boss limiting groove 3021 and transfers from the groove of the previous boss limiting groove 3021 to the next groove. As reflected on the telescopic rod 302, it is stretched to one side. By setting the boss limiting groove 3021 at different positions, the movable rod 208 can be set at different positions, and finally the folding mechanism 2 can be set at different angles. Under the action of the special-shaped plate 3031, the position of the limiting mechanism 3 can be prevented from changing.

[0033] The working process or principle of the elevator shaft installation protection device is as follows: First, place the main body of the main frame 1 into the elevator shaft, pull the movable rod 208, and the first short plate 202, the second short plate 203, the first long plate 204, and the second long plate 205 move in a scissor shape and are stretched under the action of the movable shaft, thereby driving a plurality of first folding plates 206 and second folding plates 207 to change from the folded state to the flattened state, and finally making the folding mechanism 2 longer. The movable rod 208 enters from the entry groove 101 into the movable groove 102 and is set at different positions in the movable groove 102. Pull the wrench 303, and the special-shaped plate 3031 moves on the side of the boss limiting groove 3021 and transfers from the groove of the previous boss limiting groove 3021 to the next groove. As reflected on the telescopic rod 302, it is stretched to one side. By setting the boss limiting groove 3021 at different positions, the movable rod 208 can be set at different positions, and finally the folding mechanism 2 can be set at different angles. Under the action of the special-shaped plate 3031, the position of the limiting mechanism 3 can be prevented from changing.

[0034] It should be noted that the main frame 1 is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art. Its power supply, specific composition, and principle are clear to those skilled in the art, so no further details will be elaborated.
