Description

Technical Field

[0001] The invention relates to the technical field of vibration reduction, and in particular to an elevator guide rail vibration reducer. Background Art

[0002] Equipment such as elevators that use a guide rail moving mechanism will produce inherent vibration during their normal operating cycle. The vibration propagates and diffuses along established transmission paths, such as the shaft wall and the building structure wall. The vibration energy interacts with the building structure to produce low-frequency structural noise, which poses a potential interference and impact on the surrounding environment and personnel.

[0003] In order to solve this problem scientifically and systematically, targeted vibration and noise reduction measures must be taken. Among them, installing vibration absorbers is a mature and efficient technical means and is widely used in such occasions. Through its unique mechanical design, the vibration absorber can effectively block or weaken the transmission path of vibration energy, convert vibration energy into other forms of energy for dissipation, and thus significantly reduce the negative impact of vibration on the surrounding environment and equipment.

[0004] However, the internal structure of the shock absorber in the related art is unreasonable, resulting in unsatisfactory vibration reduction effect. In order to solve this problem, the present application proposes a new shock absorber structure design. Summary of the invention

[0005] The present invention aims to solve one of the technical problems in the related art to a certain extent. To this end, the present invention provides an elevator guide rail vibration damper, which has the advantages of good vibration damping effect and compact structure.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] An elevator guide rail vibration damper comprises a shell and a vibration damper mounted on the shell, the vibration damper is used to connect the elevator guide rail, the shell is used to be fixed to the inner wall of the elevator shaft, the vibration damper comprises at least one first side plate and at least one second side plate, a plurality of the first side plates and a plurality of the second side plates are alternately arranged, and adjacent first side plates and second side plates are butted at an angle, a distance between a portion of the second side plates and the first inner wall of the shell is greater than a distance between the portion of the second side plates and the second inner wall of the shell, the first inner wall is opposite to the second inner wall, and a vibration damping material is filled between the portion of the second side plates and the first inner wall; a distance between another portion of the second side plates and the first inner wall is less than a distance between the portion of the second side plates and the second inner wall, and a vibration damping material is filled between the portion of the second side plates and the second inner wall.

[0008] In the present application, the shell is constructed as a hollow structure, the vibration damper is installed in the shell and connected to the guide rail, so that the vibration damper can absorb and disperse the vibration energy generated by the guide rail during the operation of the elevator, ensuring that the vibration damping effect is direct and efficient. The vibration damper is composed of a plurality of first side panels and a second side panel that is connected to the first side panel at a certain angle. When the vibration wave passes through the vibration damper, due to the angle connection between the side panels, the propagation direction of the vibration wave will change, forming a nonlinear vibration transmission path. The tortuosity of the nonlinear vibration transmission path causes the vibration energy to be dispersed and attenuated multiple times during the propagation process, so this type of vibration damper can provide an efficient vibration damping effect. In addition, the vibration damping member in the prior art is arranged in the middle of the shell and the vibration damping material is arranged on both sides of the vibration damping member, while in the present application, the second side plate is arranged close to the first inner wall or the second inner wall of the shell, and the second side plate and the inner wall farther away from the second side plate are filled with vibration damping material (the vibration damping material is only arranged on one side of the second side plate), that is, the vibration damping material is stacked following the arrangement direction of the second side plate. Compared with the arrangement method in which the vibration damping material is arranged on both sides of the vibration damping member in the prior art, the arrangement method of the vibration damping member and the vibration damping material in the present application requires a thinner shell thickness when the thickness of the vibration damping material is the same, which is conducive to the installation of the vibration damper.

[0009] Optionally, among two adjacent second side panels, the distance between one and the first inner wall is greater than the distance between the second inner wall, and the distance between the other and the first inner wall is less than the distance between the second inner wall, and the first side panel is connected between the two adjacent second side panels.

[0010] Optionally, the first side panel is perpendicular to the second side panel connected to the first side panel.

[0011] Optionally, when the distance between the second side plate and the first inner wall is greater than the distance between the second side plate and the second inner wall, the distance between the second side plate and the second inner wall is 2 to 8 mm.

[0012] Optionally, the distance between the first inner wall and the second inner wall is 30 to 150 mm.

[0013] Optionally, the first inner wall and the second inner wall are arranged opposite to each other along a thickness direction of the vibration-damping material, and the thickness of the vibration-damping material is 10 to 100 mm.

[0014] Optionally, a plurality of the second side panels are arranged into multiple rows and columns, the second side panels in each row are arranged along a first direction, and the second side panels in each column are arranged along a second direction, wherein the first direction intersects with the second direction.

[0015] Optionally, a plurality of second side panels are respectively arranged at opposite ends of the vibration damper and in the middle of the vibration damper, and the length of the second side panels at opposite ends of the vibration damper is smaller than the length of the second side panels in the middle of the vibration damper.

[0016] Optionally, the vibration absorber further comprises connecting members respectively arranged at opposite ends of the vibration absorber, and the connecting members comprise a straight plate for connecting the vibration absorber and an L-shaped plate for connecting the elevator guide rail.

[0017] Optionally, the shell includes a first side surface on the same side as the connecting member and a second side surface adjacent to the first side surface, and a mounting member fixed to the inner wall of the elevator shaft is provided on the first side surface and / or the second side surface.

[0018] Optionally, the mounting member is disposed on the second side surface, and a length of the mounting member is consistent with that of the second side surface.

[0019] Optionally, the mounting parts are provided at both ends of the first side surface and / or the second side surface.

[0020] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0033] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0034] Embodiment 1:

[0035] like Figures 1 to 4 As shown, this embodiment proposes an elevator guide rail vibration damper, including a shell 1 and a vibration damping member 2 installed on the shell 1, the vibration damping member 2 includes at least one first side plate 21 and at least one second side plate 22, a plurality of first side plates 21 and a plurality of second side plates 22 are alternately arranged, and adjacent first side plates 21 and second side plates 22 are butted at an angle, a distance between a portion of the second side plates 22 and the first inner wall 14 of the shell 1 is greater than a distance between the portion of the second side plates 22 and the second inner wall 15 of the shell 1, the first inner wall 14 is opposite to the second inner wall 15, and a vibration damping material 3 is filled between the portion of the second side plates 22 and the first inner wall 14; a distance between another portion of the second side plates 22 and the first inner wall 14 is less than a distance between the portion of the second side plates 22 and the second inner wall 15, and a vibration damping material 3 is filled between the portion of the second side plates 22 and the second inner wall 15.

[0036] In this embodiment, the housing 1 is constructed as a hollow structure, which includes a first inner wall 14 and a second inner wall 15 arranged opposite to each other. The vibration damper 2 is installed in the housing 1 and connected to the guide rail, so that the vibration damper 2 can absorb and disperse the vibration energy generated by the guide rail during the operation of the elevator, ensuring that the vibration damping effect is direct and efficient. The vibration damper 2 is composed of a plurality of first side panels 21 and a second side panel 22 that is connected to the first side panel 21 at a certain angle. When the vibration wave passes through the vibration damper 2, due to the angle connection between the side panels, the propagation direction of the vibration wave will change, forming a nonlinear vibration transmission path. The tortuosity of the nonlinear vibration transmission path causes the vibration energy to be dispersed and attenuated multiple times during the propagation process. Therefore, this vibration damper 2 can provide an efficient vibration damping effect. In addition, by adjusting the number, angle, material and connection method of the side panels and other parameters, the performance of the vibration damper 2 can be flexibly adjusted to meet the needs of different equipment and working conditions.

[0037] The shell 1 includes a first inner wall 14 and a second inner wall 15 arranged opposite to each other. The distance between a part of the second side plate 22 and the first inner wall 14 is greater than the distance between the part of the second side plate 22 and the second inner wall 15, that is, a part of the second side plate 22 is arranged close to the second inner wall 15. At this time, the vibration-damping material 3 is filled between the second side plate 22 and the first inner wall 14 which is farther away from the second side plate 22, so as to facilitate the placement of thicker vibration-damping material 3. The distance between another part of the second side plate 22 and the first inner wall 14 is less than the distance between the part of the second side plate 22 and the second inner wall 15, that is, another part is arranged close to the first inner wall 14. At this time, the vibration-damping material 3 is filled between the second side plate 22 and the second inner wall 15 which is farther away from the second side plate 22, so as to facilitate the placement of thicker vibration-damping material 3. In summary, in the present application, the second side plate 22 is not arranged in the middle of the shell 1, but is arranged close to the first inner wall 14 or the second inner wall 15 of the shell 1.

[0038] Due to the limited spacing between the guide rail and the side wall of the hoistway, a vibration damper that is too thick will make it impossible to install or affect the normal operation of the elevator after installation. In addition, in addition to the guide rail and vibration damper, other equipment or components such as cables and pipes may be installed in the elevator hoistway. If the vibration damper is too thick, it will interfere with these equipment or components, affecting the safety and stability of the elevator.

[0039] Compared with the linear vibration damping member 2 in the related art, the vibration damping member 2 of the present application is constructed by a first side plate 21 and a second side plate 22 connected at an angle, that is, it is constructed as a zigzag structure. The zigzag structure arranges the vibration damping material 3 arranged in a straight line in the related art in a more compact form inside the vibration damper by folding and bending, and occupies less space in the dimension perpendicular to the arrangement direction of the second side plate 22 (lateral direction), but can accumulate more material layers in the arrangement direction of the second side plate 22 (longitudinal direction). In the prior art, most of the vibration damping members 2 are constructed in a linear shape and are placed in the middle of the shell 1. Vibration damping materials 3 are placed on both sides of the vibration damping member 2, so that the shell 1 of the vibration damper has to be thickened. The second side plate 22 of the vibration damping member 2 in the present application is arranged close to the inner wall of one side of the shell 1, and a larger space is reserved on one side of the second side plate 22 to place the vibration damping material 3, while the other side does not place the vibration damping material 3. That is, there is no need to place vibration damping material 3 on both sides of the second side plate 22 like the linear vibration damping member 2 in the prior art. Therefore, the shell 1 does not need to be thickened. If you want to place the same volume of vibration damping material 3, you only need to extend the length of the shell 1 along the arrangement direction of the second side plate 22. That is, the vibration damping member 2 in the present application expands a larger space for placing the vibration damping material 3 in a direction different from the thickness direction of the shell 1 (the thickness direction refers to the direction perpendicular to the first inner wall 14 and the second inner wall 15), and the vibration damping material 3 is stacked along the arrangement direction of the second side plate 22. The vibration damper can place more vibration damping materials 3 without thickening the shell 1, and when the shell 1 has the same thickness, the vibration damper in the present application can provide a higher vibration damping efficiency, making the vibration damper structure lighter, thinner and more compact, and facilitating the installation of the vibration damper. The reduction in the thickness of the vibration damper also directly reduces the amount of shell material used, thereby reducing material costs.

[0040] It should also be noted that the thickness direction of the shell 1 in this embodiment should be consistent with the length or width direction of the elevator shaft, and the height direction of the elevator shaft should be consistent with the arrangement direction of the second side plate 22 of the vibration damping member 2. Since the height of the elevator shaft is relatively high, it is easy to understand that the second side plate 22 arranged along the height direction of the elevator shaft is not easily restricted by space. Therefore, the second side plate 22 and the vibration damping material 3 in this application can be arranged along the height direction of the elevator shaft without considering the problem of limited shaft space.

[0041] The vibration-damping material 3 can effectively disperse and absorb the vibration energy from the guide rail, increase the propagation path of the vibration energy, and disperse and absorb the energy in multiple directions, thereby reducing the impact of the vibration on the elevator system. The vibration-damping material 3 is usually a material with high damping properties, such as rubber, foam plastic, spring, etc., which can effectively absorb and disperse the vibration energy, thereby reducing the vibration amplitude transmitted to the target structure.

[0042] The first side plate 21 and the second side plate 22 are alternately arranged along a certain direction (horizontally in this embodiment, vertically in other embodiments, etc., which is not limited here), and a certain angle is formed between the adjacent first side plates 21 and the second side plates 22, thereby enclosing a vibration-damping groove 23 for filling the vibration-damping material 3. It can be understood that in this embodiment, the first side plate 21 and the second side plate 22 are not parallel or collinear, so that an open area (i.e., the vibration-damping groove 23) is formed between the two side plates, which provides the necessary space for the subsequent filling of the vibration-damping material 3. The alternating arrangement of the side plates realizes efficient vibration reduction in a limited space. Not only the vibration-damping performance is improved, but also the compactness and stability of the structure are maintained. The zigzag design makes the cross-sectional shape of the vibration-damping member 2 include multiple bending parts, increases the cross-sectional area distribution of the vibration-damping member 2 in the direction perpendicular to the vibration direction (i.e., the shear direction), and thus increases the central moment of inertia. Specifically, the zigzag shape enables the vibration-damping member 2 to more effectively disperse and resist the force that causes it to bend and deform when subjected to bending force.

[0043] In addition, the vibration absorber in this application can also be applied to a variety of scenarios that require vibration control, such as mechanical equipment and building structures. In mechanical equipment, the vibration absorber can protect the equipment from vibration damage and extend its service life; in building structures, the vibration absorber can improve the earthquake resistance of the building and ensure the safety of the structure.

[0044] It should be noted that the first side plate 21 and the second side plate 22 in this embodiment can be made of metal materials such as stainless steel and iron. In other embodiments, the first side plate 21 and the second side plate 22 can also be made of other materials with certain strength and capable of transmitting vibration energy.

[0045] Among two adjacent second side plates 22 , one is at a greater distance from the first inner wall 14 than from the second inner wall 15 , and the other is at a smaller distance from the first inner wall 14 than from the second inner wall 15 . The first side plate 21 is connected between the two adjacent second side plates 22 .

[0046] In this embodiment, the first side plate 21 and the second side plate 22 enclose a vibration-damping groove 23. Two adjacent second side plates 22, one close to the second inner wall 15 and the other close to the first inner wall 14, therefore the adjacent second side plates 22 will be symmetrical in structure but in opposite directions, i.e., a mirror effect. The adjacent vibration-damping grooves 23 will also present a mirror effect. Specifically, if a vibration-damping groove 23 is facing a certain direction (such as upward), then due to the alternating arrangement of the side plates and the existence of the mirror effect, the opening direction of the adjacent vibration-damping groove 23 will naturally face the opposite direction (such as downward). This structure is conducive to generating more reflections and refractions when the vibration wave passes through the vibration absorber, thereby increasing the transmission path of the vibration energy.

[0047] The first side plate 21 and the second side plate 22 connected to the first side plate 21 are perpendicular.

[0048] In this embodiment, the angle between the first side plate 21 and the second side plate 22 is 90°, that is, the first side plate 21 is perpendicular to the second side plate 22, and one second side plate 22 and two first side plates 21 enclose a rectangular vibration-damping groove 23, which is convenient for accommodating more vibration-damping materials 3 and reducing the thickness of the shell 1. The rectangular vibration-damping groove 23 is enclosed by two relatively parallel first side plates 21 and one second side plate 22, forming a rectangular space with an opening. In this embodiment, the angle between the first side plate 21 and the second side plate 22 is 90°, that is, they intersect vertically, which ensures the stability and structural strength of the rectangular groove. In addition, in this embodiment, the first side plate 21 and the second side plate 22 are of an integrated design. In other embodiments, the angle between the first side plate 21 and the second side plate 22 can also be 30°, 60° or other values, forming a trapezoidal vibration-damping groove 23 or a vibration-damping groove 23 of other shapes.

[0049] When the distance between the second side plate 22 and the first inner wall 14 is greater than the distance between the second side plate 22 and the second inner wall 15 , the distance between the second side plate 22 and the second inner wall 15 is 2 to 8 mm.

[0050] In this embodiment, when the distance between the second side plate 22 and the first inner wall 14 is greater than the distance between the second side plate 22 and the second inner wall 15, the vibration-damping material 3 is filled between the second side plate 22 and the first inner wall 14. At this time, there is a gap between the second side plate 22 and the second inner wall 15, and the gap is 2 to 8 mm. The gap can allow a certain amount of thermal expansion space, reduce stress concentration between different materials, or reserve space for subsequent maintenance or upgrades. When the gap is less than 2 mm, the material expansion of the vibration-damping plate will be limited, resulting in increased internal stress, and may even cause mechanical failure or structural damage. When the gap is greater than 8 mm, the placement space of the vibration-damping material 3 is reduced, reducing the overall vibration reduction effect.

[0051] The distance between the first inner wall 14 and the second inner wall 15 is 30-150 mm.

[0052] In this embodiment, the spacing between the first inner wall 14 and the second inner wall 15 is 30 to 150 mm, which provides flexibility for the layout inside the shell 1. The vibration-damping material 3 and the vibration-damping member 2 can be reasonably arranged in this space to ensure the compactness and functionality of the overall system. In addition, the spacing between the first inner wall 14 and the second inner wall 15 is similar to the thickness of the shell 1. When the spacing is less than 30 mm, the interior of the shell 1 will be too narrow and inconvenient to arrange other components. When the spacing is greater than 150 mm, the shell 1 will be too thick and inconvenient to install.

[0053] The first inner wall 14 and the second inner wall 15 are arranged opposite to each other along the thickness direction of the vibration-damping material 3 . The thickness of the vibration-damping material 3 is 10 to 100 mm.

[0054] In this embodiment, the thickness of the vibration-damping material 3 is 10 to 100 mm. When the thickness of the vibration-damping material 3 is greater than 100 mm, the excessively thick vibration-damping material 3 will occupy more space, causing the housing 1 to become too thick and inconvenient to install. When the thickness of the vibration-damping material 3 is less than 10 mm, the excessively thin vibration-damping material 3 will result in poor vibration-damping effect.

[0055] The second side plates 22 are arranged in multiple rows and columns. The second side plates 22 in each row are arranged along the first direction S1 , and the second side plates 22 in each column are arranged along the second direction S2 , wherein the first direction S1 intersects with the second direction S2 .

[0056] In this embodiment, the second side panels 22 are arranged in a plurality of rows and columns in an orderly manner. It is understandable that the first side panels 21 that are connected to the second side panels 22 at an angle are also arranged in a plurality of rows and columns in an orderly manner, so that the plurality of vibration-damping grooves 23 formed by the enclosure form a regular structure inside the shock absorber, which is conducive to enhancing the overall stability and structural strength of the shock absorber. Each row of the second side panels 22 is arranged along the first direction S1, and each column of the second side panels 22 is arranged along the second direction S2, and the first direction S1 intersects with the second direction S2, thereby increasing the transmission path of vibration energy in different directions. Specifically, in this embodiment, the vibration-damping grooves 23 formed by the first side panels 21 and the second side panels 22 are arranged in two rows and four columns. In other embodiments, the vibration-damping grooves 23 can also be arranged in other numbers of rows and columns.

[0057] In this embodiment, the first side plate 21 and the second side plate 22 are integrally connected, and the combined structure of the vibration-damping groove 23 can be made by machining on the metal plate, such as milling, using a milling machine or a CNC milling machine to directly mill the shapes of the first side plate 21 and the second side plate 22 at predetermined positions on the metal plate, or using an electric spark wire cutting machine to corrode the material through pulse discharge between the electrode wire and the workpiece, thereby cutting out the shapes of the first side plate 21 and the second side plate 22, which is suitable for processing complex shapes and high-precision vibration-damping grooves 23. In addition, the vibration-damping groove 23 can also be processed by casting, stamping, etc.

[0058] In this embodiment, a first side plate 21 is also connected between the second side plates 22 adjacent to each other in the same column. The first side plate 21 is used as a partition plate to separate the second side plates 22 in different rows and change the transmission direction of the vibration energy, thereby enhancing the vibration reduction effect. It should be noted that the first side plate 21 is placed differently from the first side plate 21 between the second side plates 22 adjacent to each other in the same row, and the positions of the two first side plates 21 are configured to be perpendicular to each other. The second side plates 22 located on both sides of the first side plate 21 extend in opposite directions to form two second side plates 22 arranged obliquely and symmetrically, further enhancing the vibration reduction effect, so that the vibration energy constantly changes direction during the transmission process, and increasing the chance of energy dissipation. When vibration occurs, the vibration propagates in different directions along the second side plates 22, and forms a reverse vibration mode between the vibration reduction grooves 23, further consuming the vibration energy and improving the vibration reduction effect.

[0059] The vibration absorber further comprises connecting members 24 respectively arranged at opposite ends of the vibration absorber 2, and the connecting members 24 comprise a straight plate 241 for connecting the vibration absorber 2 and an L-shaped plate 242 for connecting the elevator guide rail.

[0060] In this embodiment, the straight plate 241 of the connector 24 is located in the housing 1 and fixed to the vibration damper 2, and the L-shaped plate 242 extends out of the housing 1 and is connected to the guide rail through a connecting plate (not shown in the figure), so that the connector 24 can firmly connect the vibration damper 2 to the guide rail, so that the vibration damper will not loosen or fall off when subjected to vibration. In a vibration environment, the connector 24 can transfer the vibration from the guide rail to the vibration damper 2, and the vibration energy is absorbed and dissipated through the damping effect of the vibration damper 2, thereby reducing the impact on other parts of the system. When the vibration damper is subjected to a large vibration shock, the connector 24 can disperse the vibration load to avoid stress concentration from causing damage to the vibration damper 2 or the guide rail. Specifically, the connecting member 24 includes a base plate fixed to the vibrating member and a bent plate connected to the guide rail through the connecting plate. The bent plate is provided with an oblong hole (also called an oblong hole or an oblong hole) for placing fasteners (such as bolts, screws, etc.) so as to fix the connecting member 24 to the connecting plate. The design of the oblong hole allows fine-tuning of the position of the connecting member 24 during the installation process to ensure the accuracy and tightness of the connection.

[0061] In addition, the connecting member 24 is connected to two opposite ends of the vibration damping member 2 along the second direction S2. The connecting member 24 is arranged at two opposite ends of the vibration damping member 2 along this direction, so that the transmission path of the vibration energy is longer and the vibration energy loss is increased.

[0062] The housing 1 comprises a first side surface 11 on the same side as the connecting member 24 and a second side surface 12 adjacent to the first side surface 11 . A mounting member 13 fixed to the inner wall of the well is disposed on the first side surface 11 and / or the second side surface 12 .

[0063] In this embodiment, the housing 1 includes two first side surfaces 11 and two second side surfaces 12, the first side surfaces 11 and the second side surfaces 12 are perpendicular to each other, and a mounting member 13 fixed to the inner wall of the elevator shaft is provided on the first side surface 11, that is, the mounting member 13 is used to fix the shock absorber to the inner wall of the shaft. In other embodiments, the mounting member 13 may also be provided on the second side surface 12.

[0064] Mounting members 13 are disposed at both ends of the first side surface 11 and / or the second side surface 12 .

[0065] In this embodiment, the first side surface 11 and the second side surface 12 are both perpendicular to the inner wall of the elevator shaft, so the mounting member 13 is constructed in an L shape, one side of which is fixed to the surface of the housing 1, and the other side is fixed to the elevator shaft. The mounting member 13 is arranged at both ends of the two first side surfaces 11 or the two second side surfaces 12 to make the shock absorber body more evenly stressed and improve the overall stability and durability of the shock absorber. In this embodiment, the mounting members 13 are respectively arranged at both ends of the first side surface 11.

[0066] Embodiment 2:

[0067] like Figure 6 and Figure 7 As shown, the main difference between this embodiment and embodiment 1 is that, in this embodiment, multiple second side plates 22 are respectively arranged at the two opposite ends of the vibration damping member 2 along the first direction S1 and the middle part of the vibration damping member 2, and the length of the second side plates 22 located at the two opposite ends of the vibration damping member 2 along the first direction S1 is less than the length of the second side plates 22 in the middle part of the vibration damping member 2.

[0068] In this embodiment, the vibration damper 2 includes two first side plates 21 and three second side plates 22. The second side plates 22 are respectively located at both ends and the middle of the vibration damper 2. The longer middle second side plates 22 can provide more damping area, thereby more effectively absorbing and dispersing vibration energy. The shorter end second side plates 22 can guide the vibration energy to flow to the middle, reducing reflection and accumulation at the ends.

[0069] refer to Figure 1The shell 1 in the embodiment also includes two first side surfaces 11 and two second side surfaces 12, the first side surfaces 11 and the second side surfaces 12 are perpendicular to each other, and the first side surface 11 is provided with a mounting member 13 fixed to the inner side wall of the elevator shaft, that is, the mounting member 13 is used to fix the shock absorber to the inner side wall of the shaft. In other embodiments, the mounting member 13 can also be arranged on the second side surface 12. The first side surface 11 and the second side surface 12 are both perpendicular to the inner side wall of the elevator shaft, so the mounting member 13 is constructed in an L shape, one side of which is fixed to the surface of the shell 1 and the other side is fixed to the elevator shaft. In this embodiment, the mounting member 13 is arranged at both ends of the two first side surfaces 11 or the two second side surfaces 12, so that the shock absorber body is subjected to more uniform force and the overall stability and durability of the shock absorber are improved. In other embodiments, the mounting member 13 can also be arranged at both ends of the second side surface 12 respectively.

[0070] The rest of this embodiment is basically the same as that of Embodiment 1 and will not be described again here.

[0071] Embodiment 3:

The difference between this embodiment and embodiment 2 is mainly that: Figure 8 As shown, the mounting member 13 is disposed on the second side surface 12 , and the length of the mounting member 13 is consistent with the second side surface 12 .

[0073] The mounting member 13 in this embodiment is constructed as a mounting plate with the same length as the second side surface 12. The mounting plate is consistent with the length of the second side surface 12 to provide a larger contact area and a stronger supporting force, ensuring that the shock absorber can be stably fixed on the inner wall of the shaft after installation, reducing shaking or displacement caused by vibration or external force. The mounting plate is arranged on the side of the second side surface 12 away from the guide rail to facilitate connection with the inner wall of the shaft. Specifically, in this embodiment, the mounting member 13 is integrally arranged with the housing 1, and in other embodiments, the mounting member 13 and the housing 1 can also be separately arranged. Two parallel oblong holes are arranged on the mounting member 13, which are convenient for setting fasteners and adjusting the relative position with the inner wall of the shaft.

[0074] The rest of this embodiment is basically the same as that of Embodiment 2 and will not be described again here.
