[0015] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0016] This application discloses an elevator shaft pit anti-collision strip with rainwater drainage. (Refer to...) Figure 1 and Figure 2 The elevator shaft pit anti-collision strip with rainwater drainage includes the main body 1 of the elevator shaft pit, and an anti-collision strip 2 is installed on the main body 1 of the elevator shaft pit. The anti-collision strip 2 surrounds the main body 1 of the elevator shaft pit and has an entry gap 3 located at the door of the main body 1 of the elevator shaft pit.
[0017] During elevator shaft installation, the anti-collision strip 2 is fixed to the main body 1 of the elevator shaft pit. Under the action of the anti-collision strip 2, the main body 1 of the elevator shaft pit is separated from the inner wall of the pit, thereby reducing the possibility of collision between the main body 1 of the elevator shaft pit and the inner wall of the pit, and thus reducing the possibility of damage to the main body 1 of the elevator shaft pit. Under the action of the entry gap 3, it is convenient for the elevator shaft door and the elevator car door to open normally.
[0018] Reference Figure 2 and Figure 3 In this embodiment of the application, the anti-collision strip 2 includes a first strip 21 and a second strip 22. The first strip 21 is used to surround the straight section of the main body 1 of the elevator shaft pit, and the second strip 22 is used to surround the corner of the main body 1 of the elevator shaft pit. The entry notch 3 is opened on the first strip 21 and located between the two second strips 22. By installing the first strip 21 and the second strip 22 on the main body 1 of the elevator shaft pit, it is convenient to fix the anti-collision strip 2 on the main body 1 of the elevator shaft pit, and it is convenient for the anti-collision strip 2 to fit on the main body 1 of the elevator shaft pit.
[0019] Reference Figure 3 and Figure 4In this embodiment, both the first body 21 and the second body 22 include a bending plate 4. The bending plate 4 is initially a flat plate. The two sides of the bending plate 4 in the width direction are bent in opposite directions at an angle. One side of the bent plate 4 is then bent a second time. The end of the bent plate 4 after the second bend is parallel to the flat section in the middle of the bending plate 4. The middle part of the bending plate 4 and the second bend form a water-draining cavity and are fastened to the anti-collision wall of the main body 1 of the elevator shaft pit. The end of the bending plate 4 after the first bend is bent towards the water-draining cavity. The bending plate 4 is attached to the end along its length. The bending part of the bending plate 4 away from the water inlet cavity is used to attach to the anti-collision wall and fix it to the anti-collision wall. The first strip 21 and the second strip 22 are bent from the bending plate 4, which facilitates the formation of cavities in the first strip 21 and the second strip 22, thereby improving the buffering effect of the anti-collision strip 2 on the main body of the elevator shaft and thus improving the protection effect on the main body of the elevator shaft. Moreover, the bending plate 4 is bent, which facilitates the processing of the anti-collision strip 2 and reduces the manufacturing cost of the anti-collision strip 2.
[0020] Reference Figure 3 and Figure 4 Furthermore, the first body 21 is formed by splicing multiple bending plates 4 along the length direction, and the multiple bending plates 4 are spliced coaxially; the first body 21 is formed by splicing multiple bending plates 4, which reduces the length of a single bending plate 4, thereby facilitating the bending processing of the bending plate 4.
[0021] Reference Figure 3 and Figure 5 In this embodiment, a water-guiding strip 5 is also included. The water-guiding strip 5 is fixedly installed on the outside of the elevator shaft and is installed along the length of the elevator shaft. The water-guiding strip 5 is hollow. One end of the water-guiding strip 5 is connected to the rainwater guiding structure of the elevator shaft ceiling, and the other end is connected to the water-guiding cavity of the bent plate 4. Under the action of the water-guiding strip 5, the rainwater on the ceiling is guided to the anti-collision strip 2 through the water-guiding strip 5, and then the anti-collision strip 2 guides the rainwater out, thereby reducing the possibility of rainwater on the elevator shaft ceiling seeping into the elevator shaft and extending the service life of the elevator.
[0022] Reference Figure 2 , Figure 3 and Figure 5 In this embodiment, the cross-section of the water guide strip 5 is T-shaped, and the end of the water guide strip 5 is bent towards the cavity of the water guide strip 5 and parallel to the end face of the water guide strip 5. The straight lateral section of the water guide strip 5 is used to connect the side glass 6 and the glass mounting plate 7. Under the action of the water guide strip 5, while facilitating drainage, a fixing point is provided for the side glass 6 of the elevator shaft, which facilitates the installation and fixing of the side glass 6.
[0023] In this embodiment, the bottom opening of the bend of the second strip 22 is provided to allow water to drain from the anti-collision strip 2.
[0024] Reference Figure 3 and Figure 5 To reduce the possibility of clogging of the water guide strip 5, a filter screen is installed at the top of the water guide strip 5, and the filter screen spans the inner cavity of the water guide strip 5; under the action of the filter screen, the rainwater entering the water guide strip 5 is filtered, thereby reducing the possibility of clogging of the water guide strip 5 and the anti-collision strip 2.
[0025] The implementation principle of the elevator shaft pit anti-collision strip with rainwater drainage in this application embodiment is as follows: During elevator shaft installation, the anti-collision strip 2 is fixed to the main body 1 of the elevator shaft pit. Under the action of the anti-collision strip 2, the main body 1 of the elevator shaft pit is separated from the inner wall of the pit, thereby reducing the possibility of collision between the main body 1 of the elevator shaft pit and the inner wall of the pit, and thus reducing the possibility of damage to the main body 1 of the elevator shaft pit. Under the action of the entry gap 3, it is convenient for the elevator shaft door and the elevator car door to open normally.
[0026] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
