Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a vibration isolation structure for an elevator guide rail support plate. Background Technology

[0002] Utility model patent CN223292112U discloses a vibration isolation structure for an elevator guide rail support plate, including a wall and a pre-embedded steel plate installed inside the wall. An L-shaped support plate is welded and fixed to one side of the pre-embedded steel plate. A vertical connecting lug is fixedly connected to the top of the end of the L-shaped support plate away from the wall. The vertical surface of the L-shaped support plate is attached to the wall and fixedly connected to the wall by expansion bolts. A wave-shaped shock-absorbing plate is installed on the vertical surface of the L-shaped support plate. An L-shaped connecting block is fixedly connected to the other end of the wave-shaped shock-absorbing plate. The vertical surface of the L-shaped connecting block is attached to one side of the vertical connecting lug. Two fastening bolt groups are provided between the L-shaped connecting block and the vertical connecting lug. Each fastening bolt group has a locking block, and a guide rail body is engaged between the two locking blocks. The fastening bolt groups include high-strength bolts and high-strength nuts. One end of the high-strength bolt passes sequentially to the left through the locking block, the L-shaped connecting block, and the vertical connecting lug. The internal thread of the high-strength nut connects to the outer side of the left end of the high-strength bolt and is tightly locked against the left side of the vertical connecting lug. A vibration damping washer is provided between the high-strength nut and the vertical connecting lug. The front view of the corrugated shock-absorbing plate is inclined. Flexible rubber blocks are filled and fixed inside the gaps of the corrugated shock-absorbing plate. Reinforcing side edges are fixedly connected to both sides of the top of the L-shaped support plate.

[0003] The aforementioned patent has the following shortcomings: By embedding steel plates within the wall and connecting L-shaped support plates to these plates, a certain degree of vibration reduction is achieved through flexible rubber blocks and corrugated shock-absorbing plates. However, the vibration of the L-shaped support plates caused by the guide rails is directly transmitted to the embedded steel plates, resulting in wall vibration and significant noise. Utility Model Content

[0004] In view of the problems existing in the vibration isolation structure of the elevator guide rail support plate, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a vibration isolation structure for elevator guide rail support plates, which solves the problem of the aforementioned patents that, although using pre-embedded steel plates in the wall and connecting L-shaped support plates to these plates to achieve a certain vibration reduction effect through flexible rubber blocks and wave-shaped shock-absorbing plates, still results in significant noise due to the vibration of the guide rail on the L-shaped support plates, which is directly transmitted to the pre-embedded steel plates, causing wall vibration.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A vibration isolation structure for an elevator guide rail support plate includes a wall and a pre-embedded steel sleeve installed in the wall. A steel block is inserted into the pre-embedded steel sleeve, and a rubber sleeve is fitted on the steel block. A connecting component is installed at the end of the steel block, and the end of the connecting component is connected to the guide rail.

[0007] As a preferred embodiment of the vibration isolation structure for an elevator guide rail support plate described in this utility model, the outer wall of the rubber sleeve is tightly attached to the inner wall of the pre-embedded steel sleeve, and the inner wall of the rubber sleeve is tightly attached to the steel block.

[0008] As a preferred embodiment of the vibration isolation structure of the elevator guide rail support plate described in this utility model, the end of the steel block is integrally provided with a limiting disc, and the diameter of the limiting disc is larger than the outer diameter of the pre-embedded steel sleeve.

[0009] As a preferred embodiment of the vibration isolation structure of the elevator guide rail support plate described in this utility model, the end of the rubber sleeve is integrally provided with a limiting ring, and the diameter of the limiting ring is larger than the outer diameter of the pre-embedded steel sleeve.

The L-shaped support steel plate and the steel block are fixed together by bolts.

[0011] As a preferred embodiment of the vibration isolation structure of the elevator guide rail support plate described in this utility model, wherein: a butt steel plate is welded to the other side of the L-shaped support steel plate, and internal threaded holes are opened at corresponding positions of the butt steel plate and the guide rail, and the butt steel plate and the guide rail are fixed together by bolts.

[0012] As a preferred embodiment of the vibration isolation structure of the elevator guide rail support plate described in this utility model, a U-shaped block is welded to the other side of the L-shaped support steel plate, and the U-shaped block is sleeved on the guide rail. A shock absorber is bolted to the L-shaped support steel plate, and the top of the shock absorber is bolted to a mounting plate, which is welded to the guide rail.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] Example 1: This utility model provides a vibration isolation structure for an elevator guide rail support plate. Please refer to [link / reference]. Figure 1-2 The invention includes a wall 1 and a pre-embedded steel sleeve 4 installed in the wall 1. The invention is characterized in that a steel block 2 is inserted into the pre-embedded steel sleeve 4, and a rubber sleeve 3 is fitted on the steel block 2. The elastic deformation of the rubber sleeve 3 absorbs vibration energy and blocks the transmission of vibration from the steel block 2 to the pre-embedded steel sleeve 4, that is, blocks the transmission to the wall 1. A connecting component is installed at the end of the steel block 2, and the end of the connecting component is connected to the guide rail 7.

[0020] The outer wall of the rubber sleeve 3 is in close contact with the inner wall of the pre-embedded steel sleeve 4, and the inner wall of the rubber sleeve 3 is in close contact with the steel block 2.

[0021] The end of the steel block 2 is integrally provided with a limiting disc 21. The diameter of the limiting disc 21 is larger than the outer diameter of the pre-embedded steel sleeve 4, which effectively prevents the steel block 2 from detaching from the pre-embedded steel sleeve 4.

[0022] The end of the rubber sleeve 3 has an integral limiting ring 31. The diameter of the limiting ring 31 is larger than the outer diameter of the pre-embedded steel sleeve 4, so as to prevent the rubber sleeve 3 from detaching from the pre-embedded steel sleeve 4. At the same time, it cooperates with the limiting plate 21 to limit and fix the rubber sleeve 3, and enhance the vibration isolation effect.

[0023] The connecting assembly includes an L-shaped support steel plate 5. One side of the L-shaped support steel plate 5 and the corresponding position of the steel block 2 are provided with internal threaded holes. The L-shaped support steel plate 5 and the steel block 2 are fixed together by bolts to ensure connection stability.

[0024] A butt steel plate 6 is welded to the other side of the L-shaped support steel plate 5. Internal threaded holes are opened at corresponding positions of the butt steel plate 6 and the guide rail 7. The butt steel plate 6 and the guide rail 7 are fixed together by bolts.

[0025] In practical use: First, the pre-embedded steel sleeve 4 is embedded in the wall 1. After the wall 1 is formed, the steel block 2 with a rubber sleeve 3 is inserted into the pre-embedded steel sleeve 4 and limited by the limiting plate 21 and the limiting ring 31. Then, the L-shaped support steel plate 5 is fixed to the steel block 2 with bolts. Finally, the guide rail 7 is fixed to the L-shaped support steel plate 5 by the connecting steel plate 6. When the elevator is running, the vibration generated by the guide rail 7 is transmitted to the L-shaped support steel plate 5 through the connecting steel plate 6, and then to the steel block 2. The rubber sleeve 3 absorbs the vibration energy, preventing the vibration from being directly transmitted to the pre-embedded steel sleeve 4 and the wall 1, thereby reducing noise.

[0026] Example 2, see attached document Figure 3-4 Unlike Embodiment 1, a U-shaped block 8 is welded to the other side of the L-shaped support steel plate 5. The U-shaped block 8 is fitted onto the guide rail 7 and slidably connected to the guide rail 7. A shock absorber 9 is installed on the L-shaped support steel plate 5 by bolts. The top of the shock absorber 9 is connected to the mounting plate 71 by bolts. Specifically, a first mounting plate 91 is welded to the top of the shock absorber 9, and the first mounting plate 91 and the mounting plate 71 are fixed together by bolts. A second mounting plate 92 is welded to the bottom of the shock absorber 9, and the second mounting plate 92 is fixed to the L-shaped support steel plate 5 by bolts. The mounting plate 71 is welded to the guide rail 7.

[0027] In practical use: First, the pre-embedded steel sleeve 4 is embedded in the wall 1. After the wall 1 is formed, the steel block 2 with a rubber sleeve 3 is inserted into the pre-embedded steel sleeve 4 and limited by the limiting plate 21 and the limiting ring 31. Then, the L-shaped support steel plate 5 is fixed to the steel block 2 with bolts. Finally, the guide rail 7 is fixed to the L-shaped support steel plate 5 with the U-shaped block 8. When the elevator is running, the vibration generated by the guide rail 7 is transmitted to the L-shaped support steel plate 5 through the U-shaped block 8, and then to the steel block 2. The rubber sleeve 3 absorbs the vibration energy, preventing the vibration from being directly transmitted to the pre-embedded steel sleeve 4 and the wall 1, thereby reducing noise.

[0028] Furthermore, the guide rail 7 is fitted inside the U-shaped block 8 and connected to the shock absorber 9 via the mounting plate 71. When the elevator is running, the vibration generated by the guide rail 7 first absorbs part of the energy through the shock absorber 9, and the remaining vibration is transmitted to the L-shaped support steel plate 5 and steel block 2, and then further absorbed by the rubber sleeve 3, achieving double vibration isolation and better vibration isolation and noise reduction effect.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
