[0010] Preferably, both the L-shaped plate and the inner wall of the sliding plate are fixedly connected to rubber plates; multiple rubber plates are provided; thereby, the rubber plates enhance the clamping and fixing effect of the sliding plate on the wall.

[0011] Preferably, an anti-slip sleeve is fixedly attached to the surface of the rotating handle; the anti-slip sleeve is located at the end of the rotating handle; thereby the anti-slip sleeve prevents the possibility of slipping.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Specific implementation examples are given below.

[0020] like Figures 1 to 5As shown in the embodiment of this utility model, a shaft protection device for elevator engineering includes a first baffle 1, on which a first upper plate 101 is fixedly connected; a second upper plate 102 is slidably connected to the side wall of the first upper plate 101; a second baffle 109 is fixedly connected to the inner wall of the second upper plate 102; a first lower plate 103 is fixedly connected to the bottom of the first baffle 1; a second lower plate 104 is slidably connected to the side wall of the first lower plate 103; the second lower plate 104 and the second baffle 109 are fixedly connected. The first lower plate 103 has a pull rod 106 on its side wall; a spring 107 is fixedly connected to the surface of the first lower plate 103; the other end of the spring 107 is fixedly connected to the pull rod 106; the second lower plate 104 has multiple holes 108 on its side wall; the pull rod 106 and the holes 108 are correspondingly arranged; the first baffle 1 and the second baffle 109 both have fixing components 105 fixedly connected to their side walls; during operation, when protecting the elevator shaft opening, the main body of the device is first moved to the shaft opening, and the first baffle 1 side wall is first... After the wall fixing component 105 is fixed to the wall on one side of the well opening, pulling the spring 107 on the side wall of the first lower plate 103 will cause the spring 107 to drive the pull rod 106 to generate tension. At this time, the spring 107 can be pulled out from the hole 108 on the surface of the second lower plate 104. Then, by pulling the fixing component 105, the second upper plate 102 above the second baffle 109 can slide against the first upper plate 101, thereby causing the second baffle 109 to move. The fixing component 105 on one side of the second baffle 109 moves to the other side of the well opening. After the device is placed behind the wall, it is fixed to the wall by the fixing component 105. After the device is placed, the spring 107 is released. The spring 107 will be driven by the pull rod 106 and inserted into the hole 108 on the surface of the second lower plate 104, thereby fixing the first baffle 1 and the second baffle 109. Thus, the sliding of the first upper plate 101 and the second upper plate 102 can achieve the protection of well openings of different sizes. When in use, it is not necessary to measure the size of the well opening and then remake the protective device according to the size, which reduces the cost.

[0021] like Figures 1 to 5As shown, the fixing component 105 includes an L-shaped plate 201; a sliding plate 2 is slidably connected to one side of the L-shaped plate 201; a threaded rod 202 is internally threaded onto the sliding plate 2; the threaded rod 202 and the L-shaped plate 201 are in a rotational relationship; a rotating handle 203 is fixedly connected to the end of the threaded rod 202. During operation, in actual use, due to the different wall thicknesses on both sides of the well opening, it is impossible to effectively fix walls of different thicknesses. Therefore, after moving the main body of the device to one side of the well opening, the space formed by the sliding plate 2 and the L-shaped plate 201 clamps the wall. Then, by rotating the rotating handle 203, the threaded rod 202 is rotated. At this time, the sliding plate 2 will move along with the threaded rod 202 as it rotates, thus rotating the rotating handle 203 will move the sliding plate 2, clamping the wall. Thus, the sliding plate 2 achieves the clamping of walls of different thicknesses, assisting in the overall fixing effect of the device.

[0022] like Figures 1 to 5 As shown, the bottom of the L-shaped plate 201 is provided with a rotating wheel 3; multiple rotating wheels 3 are provided; the side wall of the rotating wheel 3 is threaded with a bolt 301; during operation, when moving the device or pulling the second baffle 109, the multiple rotating wheels 3 at the bottom of the air can be moved, making it easier to move the device. After the movement is completed, the bolt 301 on the side wall of the rotating wheel 3 can be rotated to fix the end of the bolt 301 to the wheel of the rotating wheel 3; thus, the rotating wheel 3 makes it easy to move the device, and the bolt 301 achieves the function of fixing the rotating wheel 3.

[0023] like Figures 1 to 5 As shown, rubber plates 4 are fixedly connected to the inner walls of both the L-shaped plate 201 and the sliding plate 2; multiple rubber plates 4 are provided; during operation, when the sliding plate 2 clamps and fixes the wall, the rubber plates 4 on the inner walls of the sliding plate 2 and the L-shaped plate 201 will contact the surface of the wall, thereby increasing the friction between the sliding plate 2 and the wall after the sliding plate 2 fixes the wall, thus strengthening the fixing effect; thus, the rubber plates 4 enhance the clamping and fixing effect of the sliding plate 2 on the wall.

[0024] like Figures 1 to 5 As shown, an anti-slip sleeve 5 is fixedly attached to the surface of the rotating handle 203; the anti-slip sleeve 5 is located at the end of the rotating handle 203; during operation, when rotating the rotating handle 203, by holding the anti-slip sleeve 5 on the surface of the rotating handle 203, the friction between the hand and the rotating handle 203 is increased, preventing the possibility of slipping due to sweating or other problems; thus, the anti-slip sleeve 5 prevents the possibility of slipping.

[0025] like Figures 1 to 4As shown, a warning plate 6 is fixedly connected to the bottom of the first upper plate 101; the warning plate 6 is located in front of the first baffle 1; during operation, at the elevator shaft opening, due to the dim environment, the warning plate 6 set at the bottom of the first upper plate 101 can issue a reminder and warning through the color and light strips on its surface in the dim environment; thus, the warning plate 6 can warn of risks and directly reduce accidents caused by personnel accidentally entering or violating regulations.

[0026] Working principle: When protecting the elevator shaft opening, the main body of the device is first moved to the opening. After fixing the fixing component 105 on the side wall of the first baffle 1 to the wall on one side of the shaft opening, the spring 107 on the side wall of the first lower plate 103 is pulled. The spring 107 will drive the pull rod 106 to generate tension. At this time, the spring 107 can be pulled out from the hole 108 on the surface of the second lower plate 104. Then, by pulling the fixing component 105, the second upper plate 102 above the second baffle 109 can slide against the first upper plate 101, thereby moving the second baffle 109. The fixing component on one side of the second baffle 109 is fixed. After component 105 is moved to the wall on the other side of the well opening, it is fixed to the wall by fixing component 105. After the device is placed, the spring 107 is released. The spring 107 is driven by the pull rod 106 and inserted into the hole 108 on the surface of the second lower plate 104, thereby fixing the first baffle 1 and the second baffle 109. In actual use, since the walls on both sides of the well opening are of different thicknesses, it is not possible to effectively fix walls of different thicknesses. At this time, after moving the main body of the device to one side of the well opening, the space formed by the sliding plate 2 and the L-shaped plate 201 clamps the wall, and then the rotating handle 2 is turned. 03 drives the threaded rod 202 to rotate. At this time, the sliding plate 2 will move along with the thread on the surface of the threaded rod 202 as it rotates. Rotating the handle 203 will then move the sliding plate 2, clamping it against the wall. When moving the device, or when pulling the second baffle 109, it can move multiple rotating wheels 3 at the bottom of the device, making movement easier. After movement, the bolts 301 on the sidewalls of the rotating wheels 3 can be rotated to fix the ends of the bolts 301 to the wheels of the rotating wheels 3. When clamping and fixing the device against the wall using the sliding plate 2, the sliding... The rubber plate 4 on the inner wall of the sliding plate 2 and the L-shaped plate 201 will contact the surface of the wall. After the sliding plate 2 is fixed to the wall, the rubber plate 4 can increase the friction with the wall, thereby strengthening the fixing effect. When rotating the handle 203, the anti-slip sleeve 5 on the surface of the handle 203 increases the friction between the hand and the handle 203, preventing slippage due to sweating or other issues. At the elevator shaft, due to the dim environment, the warning plate 6 set at the bottom of the first upper plate 101 can provide reminders and warnings in the dim environment through the colors and light strips on its surface.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
