Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an elevator shaft frame with an integrated elevator landing door device. Background Technology

[0002] An elevator shaft with integrated elevator landing door system is a modern type of elevator shaft, characterized by the installation of the elevator landing door system within the shaft itself. The advent of this type of elevator shaft makes elevator installation more convenient, operation safer, and elevates the development level of the elevator industry.

[0003] Chinese Patent CN213387358U discloses an elevator shaft frame integrating an elevator landing door device. The frame includes a shaft frame and landing door devices mounted on it. The shaft frame includes several landing openings capable of accommodating the landing door devices. Slide rails are provided at the top and bottom of each landing opening, and the landing door devices are slidably connected to these rails. Supports for placing jacks are provided on both sides of each landing opening. Push-out plates are slidably connected to the slide rails at the top and bottom of each landing opening on both sides of the landing door devices. Each push-out plate includes a vertically arranged plate body capable of abutting against the landing door devices, and sliders that can be inserted into the slide rails are provided at both the upper and lower ends of the plate body. This invention provides a solution that allows for precise adjustment of the landing door device position.

[0004] However, the inventors discovered that when passengers or goods enter the elevator through the landing door device, they are prone to colliding with the front and bottom of the landing door device, which can easily lead to damage to the landing door device. Therefore, we propose an elevator shaft with an integrated elevator landing door device. Utility Model Content

[0005] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0006] Specifically, the technical problem to be solved by this utility model is to provide an elevator shaft with an integrated elevator landing door device, so as to solve the current technical problem that passengers or goods are prone to collision with the front and bottom of the landing door device, which easily leads to damage to the landing door device.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] An elevator shaft frame integrating an elevator landing door device includes an elevator shaft frame, the elevator shaft frame having landing openings inside, the top and bottom of the landing openings having slide rails, landing door devices being installed on the two slide rails, and an installation groove being provided on the lower front of the landing door device;

[0009] Multiple damping telescopic rods are installed in the mounting groove. A bearing block is fixedly installed at one end of the damping telescopic rod away from the bottom wall of the mounting groove cavity. Two buffer airbags are installed in the mounting groove and are located next to the damping telescopic rods. A crash plate is slidably installed in the mounting groove. The crash plate is installed on the bearing block and is installed below the front of the landing door device through the bearing block.

[0010] As an improved technical solution, multiple damping telescopic rods are arranged equidistantly within the mounting groove along the length and width directions of the mounting groove.

[0011] As an improved technical solution, the two buffer airbags are symmetrically arranged along the length / width central axis of the mounting groove.

[0012] As an improved technical solution, the anti-collision plate has a double-layer structure of an integrally molded inner plate and an outer rubber plate;

[0013] The inner plate has multiple rectangular slots that correspond to the multiple support blocks. The support blocks are fixedly installed in the rectangular slots, and the anti-collision plate is installed on the support blocks through the rectangular slots.

[0014] As an improved technical solution, a plurality of rectangular grooves are arranged at equal intervals along the length and width directions of the inner plate, and the rectangular grooves are adapted to the bearing block.

[0015] As an improved technical solution, multiple sound-absorbing cottons are installed in the mounting groove. The multiple sound-absorbing cottons are arranged at equal intervals along the length / width direction of the mounting groove and are symmetrically arranged along the length / width central axis of the mounting groove.

[0016] The surface of the sound-absorbing cotton has several small holes, which are used to increase the surface area.

[0017] As an improved technical solution, two sound-absorbing panels are installed in the mounting groove, and the two sound-absorbing panels are symmetrically arranged along the length / width central axis of the mounting groove;

[0018] The sound-absorbing panel is made of a porous rigid material, and its surface is embedded with a refractive textured structure, which is used to absorb high-frequency and mid-high-frequency sound waves.

[0019] After adopting the above technical solution, the beneficial effects of this utility model are:

[0020] 1. This utility model uses the outer rubber plate of the anti-collision plate to initially buffer the impact force. At the same time, the inner plate of the anti-collision plate drives multiple bearing blocks to move. The multiple bearing blocks distribute the impact force to multiple damping telescopic rods, and the damping telescopic rods further buffer and absorb the remaining impact force. When the inner plate touches the buffer airbag, the buffer airbag, which undergoes elastic deformation, buffers the impact force again and also acts as a limit. This improves the anti-collision performance of the landing door device and ensures the normal operation of the elevator, while reducing damage to passengers or goods.

[0021] 2. In this utility model, the noise generated by the impact can be absorbed and reduced by sound-absorbing cotton and sound-absorbing board. The small pores on the surface of the sound-absorbing cotton can greatly increase the surface area to improve the sound absorption and sound insulation performance. The refractive concave and convex structure on the surface of the sound-absorbing board can effectively absorb high-frequency and mid-high-frequency sound waves to achieve noise reduction of the sound generated by the impact.

[0033] Reference Figure 1-4 An elevator shaft frame integrating an elevator landing door device is provided. The elevator shaft frame integrating the elevator landing door device includes an elevator shaft frame 1. The elevator shaft frame 1 has a landing opening 2 inside. The top and bottom of the landing opening 2 are provided with slide rails. A landing door device 3 is installed on the two slide rails. An installation groove 301 is opened on the lower front of the landing door device 3.

[0034] Multiple damping telescopic rods 4 are installed in the mounting groove 301. A bearing block 5 is fixedly installed at the end of the damping telescopic rod 4 away from the bottom wall of the inner cavity of the mounting groove 301. Two buffer airbags 6 are installed in the mounting groove 301. The buffer airbags 6 are located next to the damping telescopic rods 4. A crash plate is slidably installed in the mounting groove 301. The crash plate is installed on the bearing block 5 and is installed on the front and below the landing door device 3 through the bearing block 5.

[0035] Reference Figure 2 and Figure 3Multiple damping telescopic rods 4 are arranged at equal intervals along the length and width of the mounting groove 301 within the mounting groove 301 to buffer and absorb energy impact forces.

[0036] Reference Figure 2 and Figure 3 Two buffer airbags 6 are symmetrically arranged along the length / width central axis of the mounting groove 301 to further buffer the impact force and limit its movement.

[0037] Reference Figure 1 , Figure 2 as well as Figure 4 The anti-collision plate has a double-layer structure consisting of an integrally molded inner plate 701 and an outer rubber plate 702;

[0038] The inner plate 701 has multiple rectangular slots 703 that correspond to the multiple bearing blocks 5 respectively. The bearing blocks 5 are fixedly installed in the rectangular slots 703, and the anti-collision plate is installed on the bearing blocks 5 through the rectangular slots 703.

[0039] Reference Figure 4 Multiple rectangular grooves 703 are arranged at equal intervals along the length and width of the inner plate 701, and the rectangular grooves 703 are adapted to the bearing block 5 so as to facilitate the assembly of the inner plate 701 onto the bearing block 5.

[0040] Reference Figure 2 and Figure 3 Multiple sound-absorbing cotton 8 are installed in the mounting groove 301. The multiple sound-absorbing cotton 8 are arranged at equal intervals along the length / width direction of the mounting groove 301 and are symmetrically arranged along the length / width central axis of the mounting groove 301.

[0041] The surface of the sound-absorbing cotton 8 has several small holes (not shown in the figure). The small holes are used to increase the surface area to improve the sound absorption and sound insulation performance, thereby facilitating the reduction of noise generated by impact.

[0042] Reference Figure 2 and Figure 3 Two sound-absorbing panels 9 are installed in the mounting groove 301, and the two sound-absorbing panels 9 are symmetrically arranged along the length / width central axis of the mounting groove 301;

[0043] The sound-absorbing panel 9 is made of a porous rigid material, and the surface of the sound-absorbing panel 9 is embedded with a refractive convex-concave structure (not shown in the figure). The refractive convex-concave structure is used to absorb high-frequency and mid-high-frequency sound waves, so as to effectively absorb high-frequency and mid-high-frequency sound waves, thereby facilitating noise reduction of the sound generated by the impact.

[0044] In actual use, when a passenger or cargo collides with the front of the landing door device 3, the outer rubber plate 702 on the anti-collision plate initially buffers the impact force. At the same time, the inner plate 701 on the anti-collision plate drives multiple bearing blocks 5 to move. The multiple bearing blocks 5 distribute the impact force to multiple damping telescopic rods 4, and the damping telescopic rods 4 further buffer and absorb the remaining impact force. When the inner plate 701 touches the buffer airbag 6, the buffer airbag 6, which undergoes elastic deformation, buffers the impact force again and also acts as a limit, thereby improving the anti-collision performance of the landing door device 3 and ensuring the normal operation of the elevator, while reducing damage to passengers or cargo.

[0045] At the same time, the noise generated by the impact can be absorbed and reduced by the sound-absorbing cotton 8 and the sound-absorbing panel 9. The small holes on the surface of the sound-absorbing cotton 8 can greatly increase the surface area to improve the sound absorption and sound insulation performance. The refractive concave and convex structure on the surface of the sound-absorbing panel 9 can effectively absorb high-frequency and mid-high-frequency sound waves to reduce the noise generated by the impact. This device can not only improve the anti-collision performance of the landing door device 3 to ensure the normal operation of the elevator, but also reduce the damage to passengers or goods.
