[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] Furthermore, the terms "first," "second," and "third" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0026] like Figure 1 , Figure 2 and Figure 4As shown, an elevator shaft protection device includes a guide rail frame, a movable protective door 4, and a fixed protective door 3. The guide rail frame includes two guide rails 2 vertically arranged inside the elevator shaft 1 at the shaft opening 101, and an upper connecting rod 5 and a lower connecting rod 6 for connecting the two guide rails 2. A transverse fixing rod 7 is fixed on the upper connecting rod 5 and the lower connecting rod 6, extending along the direction of the shaft opening 101 and fixedly connected to the inner wall of the shaft opening 101 by expansion bolts 8. Specifically, to facilitate processing and save manufacturing costs, the guide rails 2, the upper connecting rod 5, the lower connecting rod 6, and the transverse fixing rod 7 are all made of angle steel. The movable protective door 4 and the fixed protective door 3 are grid-type protective doors welded from multiple square tubes. The vertical section of the guide rail 2 is set parallel to the opening direction of the well opening 101, and the horizontal sections of the two guide rails 2 are set opposite each other. The fixed protective door 3 is located in the middle of the guide rail frame and is fixedly connected to the end faces of the vertical sections of the two guide rails 2. The movable protective door 4 is slidably connected to the two guide rails 2 on both sides, and there are sliding channels between the fixed protective door 3 and the guide rail 2, and between the upper connecting rod 5 and the guide rail 2, for the movable protective door 4 to enter and exit. The lower connecting rod 6 forms a limiting part that restricts the downward movement of the movable protective door 4. By setting the guide rail frame inside the elevator shaft 1 and fixing it to the inside of the well opening 101 by the horizontal fixing rod 7, the overlap between the protective door and part of the wall outside the well opening 101 is avoided. Furthermore, since the device does not need to be connected to the wall outside the well opening 101, the protective device can be installed before the wall is built, achieving full protection during the construction of the well opening 101. Figure 3 As shown, the movable protective door 4 can slide vertically within the sliding channel of the guide rail 2, so that when it is necessary to temporarily enter or exit the wellhead 101, the protective device can be temporarily opened by pulling up the movable protective door 4, ensuring the convenience of the device.

[0027] To ensure the smooth sliding of the movable protective door 4, such as Figure 6 As shown, the movable protective door 4 has a guide wheel 401 rotatably mounted on its back side, which slides in cooperation with the horizontal end face of the angle steel. Preferably, there are four guide wheels 401, arranged in two groups vertically on both sides of the movable protective door 4.

[0028] The distance between the fixed protective door 3 and the lower connecting rod 6 is 1.35m-1.5m. In this embodiment, the distance is 1.35m. The height of the movable protective door 4 is 1.4m. The height of the temporary passage formed by pulling up the movable protective door 4 is 1.35m. In order to ensure the stability of the movable protective door 4 on the guide rail 2 and to prevent it from moving forward when sliding, side baffles 9 are fixed on the outer sides of the two guide rails 2 above the lower connecting rod 6 and below the fixed protective door 3, respectively.

[0029] More preferably, kick plates 12 are fixed to the outer sides of the two side baffles 9 above the lower connecting rod 6 to improve the protection effect on the lower end of the movable protective door 4.

[0030] like Figure 7 As shown, the fixed protective door 3 is equipped with a spring pull pin 11. The spring pull pin 11 is existing technology, and its internal structure will not be described in detail. The shell of the spring pull pin 11 is fixed through the frame of the fixed protective door 3 corresponding to the guide rail 2. The pin head of the spring pull pin 11 is set towards the guide rail 2. The lower end of the movable protective door 4 is provided with a positioning hole that cooperates with the pin head of the spring pull pin 11. Through the cooperation of the spring pull pin 11 and the positioning hole, the position of the pulled-up movable protective door 4 is locked, thereby forming a stable temporary entrance.

[0031] like Figure 4 and Figure 5 As shown, in order to accommodate elevator shaft openings of different heights, the upper connecting rod 5 is fixed with U-shaped frames 10 arranged vertically at both ends. The openings of the two U-shaped frames 10 are arranged opposite each other and the U-shaped frames 10 are slidably connected to the guide rail 2.

[0032] When implementing the above technical solution, 40*40*4mm angle steel is used as the material for the guide rail 2, upper connecting rod 5, lower connecting rod 6 and horizontal fixing rod 7. 20*20*2mm square tube is used as the material for the movable protective door 4 and fixed protective door 3. The height of the elevator shaft is 1.8m. The finished fixed protective door 3 is 0.3m high, the movable protective door 4 is 1.4m high, and the kick plate 12 is 0.18m high. The protective devices are welded and assembled. The U-shaped frame 10 of the upper connecting rod 5 is sleeved on the outer side of the upper end of the guide rail frame. The horizontal fixing rod 7 of the lower connecting rod 6 is fixed to the bottom of the shaft 101 by expansion bolts 8. The upper connecting rod 5 moves up along the guide rail 2 until the horizontal fixing rod 7 contacts the top of the shaft 101 and is fixed with expansion bolts 8. At this time, the movable protective door 4 falls on the lower connecting rod 6, forming a temporary protective door for the elevator shaft.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
