Background Art

[0002] With the continuous advancement of urbanization in my country, the construction of high-rise buildings is increasing to improve land use efficiency, and the number of elevators is correspondingly increasing year by year. Currently, elevator guide rails are mostly fixed to the building structure within the entrance using steel fixing plates. During elevator operation, friction vibrations between the guide shoes and the guide rails are transmitted to the elevator car through the traction rope, affecting the passenger comfort experience. In addition, vibrations are transmitted to the building structure through the elevator guide rails and their rigid connections, generating secondary noise that adversely affects the living or working environment of building residents. In summary, the market urgently needs to provide elevator guide rails with lower vibration and noise levels. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned defects and provide a low-noise elevator guide rail with lower vibration and noise levels.

[0004] The utility model is realized as follows: the low-noise elevator guide rail comprises a guide rail body, a restraint damping device is fixedly arranged on the non-working surface of the guide rail body, the restraint damping device comprises a damping layer and a restraining plate, and the damping layer is arranged between the guide rail body and the restraining plate.

[0005] In the restraint damping device, the specific form of the restraint plate can be various. For example, the restraint plate includes a panel and / or a bottom plate, or the restraint plate includes a panel and a combination plate, or the restraint plate only includes a combination plate, or the restraint plate includes a left combination plate and a right combination plate. In addition, the specific form of the panel can also be changed. Based on the above description, the typical technical solutions of the utility model include: (1) the panel includes a left panel and a right panel, the bottom plate is provided with bending parts on both sides of the rail bottom of the guide rail body, and the left panel and the right panel are buckled on the surface of the guide rail body through the bending parts; (2) the panel includes a left panel and a right panel, the left panel and the bottom plate, and the right panel and the bottom plate are fixed together on the outside of the guide rail body by fasteners; (3) the panel includes a left panel and a right panel, the bottom plate is provided with bending parts on both sides of the rail bottom of the guide rail body, the left panel and the right panel are provided with matching bending parts, and the bending part of the bottom plate is fixed with the mounting of the left panel The matching bending portion and the bending portion of the bottom plate are respectively engaged with the assembly bending portion of the right panel; (4) the constraint plate includes a panel and a combination plate, the combination plate covers the non-working surface and bottom surface of the guide rail body on one side, and the panel covers the non-working surface of the guide rail body on the other side, and the combination plate and the panel are fixed together on the outside of the guide rail body by fasteners; (5) the constraint plate includes a combination plate, the combination plate covers the non-working surface and rail bottom surface of the rail waist and wing plates on both sides of the guide rail body; (6) the constraint plate includes a left combination plate and a right combination plate, the left combination plate covers the non-working surface and left rail bottom surface of the left guide rail body, and the right combination plate covers the non-working surface and right rail bottom surface of the right guide rail body; (7) It should be pointed out that for the technical solution using a panel, as a special case, the panel includes a left panel and a right panel, the left panel includes a left waist plate and a left wing plate, and the right panel includes a right waist plate and a right wing plate.

[0006] To facilitate engineering applications, the damping layer and the restraining plate in the constrained damping device of the present invention are preferably integrated into one piece. Furthermore, to ensure safety and prevent the unintended separation of the constrained damping device from the guide rail body, which could lead to hazards, the low-noise elevator guide rail of the present invention may also include a spring clamp that secures the constrained damping device to the surface of the guide rail body. Alternatively, the constrained damping device may be directly affixed to the guide rail body by adhesive bonding or secured to the guide rail body using fasteners.

[0007] To ensure effective vibration and noise reduction, the restrained damping device is preferably provided continuously along the length of the guide rail body. However, for safety reasons, the restrained damping device may be provided away from the fixed fastening members of the guide rail body. Furthermore, the restrained damping device, consisting of the damping layer and the restraining plate, may be provided in multiple layers, with the multiple layers of restrained damping devices stacked one on top of the other.

[0008] The low-noise elevator guide rail of the present invention can effectively suppress the friction vibration between the guide shoe and the guide rail body during the operation of the elevator by adding a constraint damping device to the non-working surface of the guide rail body. When vibration occurs, the surface of the guide rail body is forced to deform. Due to the limitation of the constraint plate, the damping layer will be repeatedly sheared and squeezed, and the mechanical energy will be converted into heat energy and dissipated. In this process, the vibration energy of the guide rail body can be quickly consumed, and the vibration intensity of the guide rail body can be significantly reduced. Therefore, on the one hand, the vibration intensity transmitted to the elevator car through the guide rail body is greatly reduced, and the comfort of passengers riding the elevator is greatly improved; on the other hand, the vibration intensity transmitted to the building structure through the elevator guide rail and its rigid connection is also greatly reduced, and the secondary noise level of the building structure is also effectively suppressed, which is conducive to better improving the living or working environment of the residents in the building. At the same time, it can also effectively prevent fatigue damage to the building structure, which is conducive to extending the service life of the building structure.

[0009] To sum up, the low-noise elevator guide rail of the utility model has a simple structure, good vibration reduction effect, lower vibration and noise levels during use, better comfort and environmental protection, and can be widely used in elevator projects in various buildings such as residential buildings, office buildings, and shopping malls.

[0022] Example 1

[0023] like Figure 1 The low-noise elevator guide rail of the present invention comprises a guide rail body 1, with a restrained damping device fixedly disposed on the non-working surface of the guide rail body. The restrained damping device comprises a damping layer 3 and a restraining plate. The restraining plate comprises a panel 2, which covers a portion of the guide rail body's rail waist and a portion of the flange surface. The damping layer 3 is disposed between the guide rail body 1 and the panel 2. The restrained damping device is continuously disposed along the length of the guide rail body 1, with the panel 2's length at the flange completely avoiding the buckling position of the fixed buckling member.

[0024] During use, the low-noise elevator guide rail of this utility model is secured to the corresponding structural surface of the elevator shaft using a fixing clamp. The fixing clamp is directly clamped onto the surface of the guide rail body, which is exactly the same as the fixing method of existing elevator guide rails, ensuring safety and reliability. The restraining plate can be made of metal sheet materials such as thin steel plate and aluminum alloy profiles, or non-metallic sheet materials such as fiberglass. As long as the strength is sufficient, it can be used in this utility model. In practice, the choice can be based on project needs.

[0025] The low-noise elevator guide rail of the present invention can greatly reduce the friction vibration intensity between the guide shoe and the guide rail body during the operation of the elevator by adding a constraint damping device to the non-working surface of the guide rail body. When vibration occurs, the surface of the guide rail body is forced to deform. Due to the limitation of the constraint plate, the damping layer will be repeatedly sheared and squeezed, and the mechanical energy will be converted into heat energy and dissipated. In this process, the vibration energy of the guide rail body can be quickly consumed, and the vibration intensity of the guide rail body can be significantly reduced. Therefore, on the one hand, the vibration intensity transmitted to the elevator car through the guide rail body is greatly reduced, and the comfort of passengers riding the elevator is greatly improved; on the other hand, the vibration intensity transmitted to the building structure through the elevator guide rail and its rigid connection is also greatly reduced, and the secondary noise level of the building structure is also effectively suppressed, which is conducive to better improving the living or working environment of the residents in the building. At the same time, it can also effectively prevent fatigue damage to the building structure, which is conducive to extending the service life of the building structure.

[0026] To sum up, the low-noise elevator guide rail of the utility model has a simple structure, good vibration reduction effect, lower vibration and noise levels during use, better comfort and environmental protection, and can be widely used in elevator projects in various buildings such as residential buildings, office buildings, and shopping malls.

[0027] Example 2

[0028] like Figure 2 The low-noise elevator guide rail of the present invention differs from the first embodiment in that, in the constrained damping device, the constraining plate includes a bottom plate 6, a damping layer 3 is disposed between the bottom plate 6 and the guide rail body 1, and bent portions A are provided on both sides of the bottom plate 6, which are clamped to the edges of the guide rail body's wing plates via the bent portions A. The bottom plate 6 is spaced apart from the guide rail body's wing plates, avoiding the fixed clamping members.

[0029] Similar to the energy dissipation principle of Example 1, the technical solution described in this example can significantly reduce the friction vibration intensity between the guide shoe and the guide rail body during elevator operation by adding a constrained damping device to the non-working surface of the guide rail body, which is beneficial to significantly improve the comfort of passengers riding the elevator and improve the living or working environment of residents in the building. At the same time, it can also effectively prevent fatigue damage to the building structure, which is beneficial to extending the service life of the building structure.

[0030] Example 3

[0031] like Figure 3 The low-noise elevator guide rail of the present invention includes a guide rail body 1. A constrained damping device is fixedly installed on the non-working surface of the guide rail body. The constrained damping device includes a damping layer 3 and a constraining plate. The constraining plate includes a composite plate 8. The damping layer 3 is arranged between the guide rail body 1 and the composite plate 8. The composite plate 8 covers all non-working surfaces of the guide rail body 1, including the rail waist, flange, and rail bottom.

[0032] During manufacturing, a layer of solid damping material can be pre-coated on the non-working surface of the elevator guide rail body. A composite plate can then be placed over the guide rail body and the solid damping material, controlling the thickness of the damping layer. Once the solid damping material solidifies, the damping layer is formed. The composite plate can then be bonded to the guide rail body using the damping layer. The composite plate can be made of metal sheet materials such as thin steel or aluminum alloy profiles, or non-metallic sheet materials such as fiberglass reinforced plastics. As long as the strength is sufficient, any material can be used in the present invention. The choice of material can be determined based on project requirements. In engineering applications, the low-noise elevator guide rail of the present invention can be fixed to the surface of the elevator shaft structure using fixed clamps, similar to the fixing method used for existing elevator guide rails. To ensure effective vibration and noise reduction, constrained damping devices should be installed on as many non-working surfaces of the elevator guide rail body as possible. If necessary, the fixed clamps can be partially avoided. Alternatively, the fixed clamps can be directly attached to the exterior of the constrained damping device while ensuring safety. In practice, the design and selection should be based on the specific conditions of the constrained damping device and the actual needs of the project.

[0033] The low-noise elevator guide rail of the present invention can effectively suppress the friction vibration between the guide shoe and the guide rail body during the operation of the elevator by adding a constraint damping device to the non-working surface of the guide rail body. When vibration occurs, the surface of the guide rail body is forced to deform. Due to the limitation of the constraint plate, the damping layer will be repeatedly sheared and squeezed, and the mechanical energy will be converted into heat energy and dissipated. In this process, the vibration energy of the guide rail body can be quickly consumed, and the vibration intensity of the guide rail body can be significantly reduced. Therefore, on the one hand, the vibration intensity transmitted to the elevator car through the guide rail body is greatly reduced, and the comfort of passengers riding the elevator is greatly improved; on the other hand, the vibration intensity transmitted to the building structure through the elevator guide rail and its rigid connection is also greatly reduced, and the secondary noise level of the building structure is also effectively suppressed, which is conducive to better improving the living or working environment of the residents in the building. At the same time, it can also effectively prevent fatigue damage to the building structure, which is conducive to extending the service life of the building structure.

[0034] To sum up, the low-noise elevator guide rail of the utility model has a simple structure, good vibration reduction effect, lower vibration and noise levels during use, better comfort and environmental protection, and can be widely used in elevator projects in various buildings such as residential buildings, office buildings, and shopping malls.

[0035] Example 4

[0036] like Figure 4The low-noise elevator guide rail of the present invention shown in the figure is different from the third embodiment in that the constraint plate in the constraint damping device includes a panel and a bottom plate 6, wherein the panel includes a left panel 4 and a right panel 5, and the bottom plate 6 is provided with bending portions A on both sides of the rail bottom corresponding to the guide rail body 1, and the left panel 4 and the right panel 5 are pressed against the surface of the guide rail body 1 through the bending portions A; in addition, the damping layer 3 is pre-integrated with the left panel 4, the right panel 5 and the bottom plate 6.

[0037] Compared to Example 1, the technical solution described in this example utilizes a split-type structure for the constraint plate, split into three parts: a left panel 4, a right panel 5, and a bottom plate 6. Simultaneously, the damping layer 3 is pre-integrated with the left panel 4, the right panel 5, and the bottom plate 6. This technical solution significantly reduces the difficulty of installing the constraint plate and effectively ensures that the thickness of the damping layer remains uniform, thus ensuring that the constrained damping device has stable vibration and noise reduction performance. It should be noted that to ensure the reliability of the connection between the split-type constraint plate and the guide rail body, adhesive can be used to auxiliaryly bond the left panel 4, the right panel 5, and the bottom plate 6 to the surface of the guide rail body.

[0038] Example 5

[0039] like Figure 5 The low-noise elevator guide rail of the present invention shown here is different from the fourth embodiment in that the panel includes a left panel and a right panel, the left panel includes a left waist panel 9 and a left wing panel 10, and the right panel includes a right waist panel 11 and a right wing panel 12; in addition, the constrained damping device consisting of the left waist panel 9 and the damping layer 3 and the right waist panel 11 and the damping layer 3 is fixedly connected to the guide rail body 1 by a connecting fastener 13, one end of the left wing panel 10 is pressed by the left waist panel, and the other end is buckled by the bent portion A of the bottom plate 6, thereby being pressed against the left wing panel surface of the guide rail body 1. Similarly, the right wing panel 12 is pressed against the right wing panel surface of the guide rail body 1 by the right waist panel 11 and the bent portion A.

[0040] Compared to the technical solution described in Example 4, the addition of the connecting fasteners 13 makes the connection and fixation between the left and right waist panels and the guide rail body more reliable and safer. In addition, the panel adopts a further split structure, which is conducive to better adapting to the different confined spaces on different surfaces of the guide rail body. For example, to avoid the guide shoe, the left and right waist panels can be made of thinner plates, while the left and right wing panels can be made of thicker plates. This arrangement allows the use of plates that meet different functional requirements according to the confined space, wear resistance requirements, corrosion resistance requirements, and insulation requirements. This is conducive to better meeting engineering needs and ensuring performance requirements, while also helping to control material costs.

[0041] Example 6

[0042] like Figure 6 The low-noise elevator guide rail of the present invention shown in the figure differs from the fourth embodiment in that the left side panel 4 and the bottom plate 6, as well as the right side panel 5 and the bottom plate 6, are fixed together on the outside of the guide rail body 1 by fasteners 7, specifically by rivets. In addition, as an auxiliary fixing measure, an adhesive (not specifically shown in the figure) is used to adhere and fix the left side panel 4, the right side panel 5 and the bottom plate 6 with the integrated damping layer 3 to the surface of the guide rail body 1.

[0043] Compared with the fourth embodiment, the technical solution described in this embodiment uses adhesives and fasteners to connect the split restraint plates together, which has a more reliable connection effect and better integrity and safety.

[0044] Example 7

[0045] like Figure 7 The low-noise elevator guide rail of the present invention shown here differs from that of Example 6 in that the restraining plate includes a panel and a composite panel. Taking the left panel 4 as an example, the panel covers the non-working surface of the left guide rail body 1, and the composite panel 8 covers the non-working surface and bottom surface of the other guide rail body 1. The composite panel 8 and the left panel 4 are fixed together on the outside of the guide rail body 1 by fasteners 7. In addition, the left panel 4 only covers the non-working surface of a portion of the left rail waist, and similarly, the composite panel 8 only covers the non-working surface of a portion of the right rail waist.

[0046] Compared with the sixth embodiment, in the technical solution described in this example, the right side panel and the bottom plate are integrated using a combination plate, which involves fewer parts, simplifies the assembly operation, and provides a safer and more reliable fixing effect.

[0047] based on Figure 7 The technical principles described in the invention can also be used to use the right side panel as a panel to cover the right side non-working surface of the guide rail body, and then use the combined panel to cover the left side non-working surface of the guide rail body and the rail bottom surface, so as to achieve similar technical effects. These are simple changes based on the technical principles of the present invention and are all within the scope of protection required by the present invention. It should be pointed out in particular that in the technical solutions described in this example and in Example 4, the panels are divided into left and right panels only according to the different assembly positions on the surface of the guide rail body. The panels are actually universal. That is to say, the constraint plate in Example 4 involves two components, the panel and the bottom plate. The specific application involves the assembly of three components, two panels and one bottom plate. The constraint plate in this example involves two components, the panel and the combined panel, but the specific application only involves the assembly of two components, one panel and one combined panel, so the assembly operation is simpler.

[0048] In addition, in this example, the panel and the combined plate do not completely cover the non-working surface of the rail waist of the guide rail body. The technical principle to be explained is that in the present invention, the constraint plate does not need to completely cover all non-working surfaces of the guide rail body. It can be partially avoided according to the actual requirements of the project. It does not have to be set continuously or completely covered. It can be designed and arranged according to the needs of the project. This feature is also applicable to other embodiments of the present invention, which are explained here.

[0049] Example 8

[0050] like Figure 8 The low-noise elevator guide rail of the present invention shown here differs from the third embodiment in that the restraining plate includes a left-side combined plate 14 and a right-side combined plate 15. The left-side combined plate 14 covers the non-working surface of the left guide rail body 1 and the left rail bottom surface, while the right-side combined plate 15 covers the non-working surface of the right guide rail body 1 and the right rail bottom surface. In addition, the left-side combined plate 14 (including the damping layer 3) and the right-side combined plate 15 (including the damping layer 3) are respectively fixedly connected to the guide rail body 1 using connecting fasteners 13.

[0051] Compared with the third embodiment, the technical solution described in this embodiment is simpler and faster to assemble, and the installation and fixing effect is safer and more reliable.

[0052] Embodiment 9

[0053] like Figure 9 The low-noise elevator guide rail of the utility model shown here differs from the fourth embodiment in that a bottom plate 6 is provided with bent portions A on both sides of the rail bottom of the guide rail body 1, and a matching bent portion B is provided on the left panel 4 and the right panel 5 respectively. The bent portion A of the bottom plate 6 and the assembly bent portion B of the left panel and the bent portion A of the bottom plate and the assembly bent portion B of the right panel are respectively embedded with each other.

[0054] Compared with the fourth embodiment, the advantage of the technical solution described in this example is that the matching bent portions B are respectively provided on the left panel 4 and the right panel 5, which is conducive to improving the local rigidity of the panel; and for the technical solution in which the bent portion A of the bottom plate is buckled on the panel surface in the fourth embodiment, when the guide ladder body is fixedly installed on the surface of the elevator shaft structure by using a fixed buckling piece, if the fixed buckling piece is directly buckled on the bent portion A, due to the two layers of constraint plates and damping layers stacked below, and the rigidity provided by the bent portion is relatively large, the fixed buckling piece is difficult to press and flatten, and the use of the fixed buckling piece is not satisfactory. It is easy to loosen during the installation process, so the restrained damping device can only partially avoid the setting of the fixed buckling parts. However, in the technical solution described in this example, the cooperation of the bent part A and the bent part B is located on both sides of the bottom of the guide rail body. When the guide ladder body is fixedly installed on the surface of the elevator shaft structure using the fixed buckling parts, the fixed buckling parts can be directly buckled on the panel, and the clamping force of the fixed buckling parts can be properly controlled. In engineering applications, there is no need to avoid the fixed buckling parts, and the restrained damping device can be continuously set on the guide rail body, which is beneficial to further improve the vibration reduction and noise reduction effect.

[0055] Of course, based on Figure 9 The technical principles recorded in the technical solution, such as Figure 10 As shown in FIG, the bent portion A can also be embedded inside the assembly bent portion B. In addition, the entire restraint damping device can be fixedly connected to the guide rail body using connecting fasteners 13, which is safer and more reliable. These are simple variations based on the present invention and are all within the scope of protection claimed by the present invention.

[0056] Example 10

[0057] like Figure 11 The low-noise elevator guide rail of the present invention shown here differs from the ninth embodiment in that it further comprises a spring clamp 16 , which clamps and fixes the restraining damping device on the surface of the guide rail body 1 .

[0058] During use, the restraining damping device can be clamped and fixed to the surface of the guide rail body 1 by using spring clamps to cooperate with each other on the left and right sides. Compared with the fifth embodiment, the addition of spring clamps not only ensures that the restraining damping device is closely attached to the surface of the guide rail body, but also effectively prevents the danger caused by the restraining plate accidentally falling off. Therefore, while maintaining the vibration and noise reduction performance, the safety and reliability of the system are greatly improved.

[0059] Example 11

[0060] like Figure 12 The utility model low noise elevator guide rail is shown, and Figure 10 The difference of the technical solution shown is that a constrained damping structure consisting of a left wing plate 10 and a damping layer 3 is added to the outer surface of the left panel 4, and at the same time, a constrained damping structure consisting of a right wing plate 12 is added to the outer surface of the right panel 5.

[0061] and Figure 10 Compared with the technical solution shown in the embodiment, in the technical solution described in this example, since a multi-layer constrained damping structure stacked on each other is provided at the wing plate of the guide rail body, it is beneficial to further improve the vibration reduction and noise reduction effect.

[0062] This example uses the example of setting two layers of constrained damping devices at the wing plate of the guide rail body as an example to illustrate. Based on the technical principles described in this example, in order to achieve better vibration and noise reduction effects, on the one hand, in addition to the wing plate of the guide rail body mentioned above, the present invention can also set multiple layers of mutually overlapping constrained damping devices at other locations such as the rail waist and rail bottom, or at all locations; on the other hand, in addition to setting two layers, the constrained damping devices can also be set at three or even more layers. As long as they do not exceed the limit, they can be applied to the present invention. These are all simple changes based on the technical principles of the present invention, and can also achieve good technical effects. They are only described in text here, and no drawings are provided one by one. They are all within the scope of protection required by the present invention.

[0063] The embodiments in the present invention are only for better illustrating the technical solutions of the present invention and should not be regarded as limiting the present invention. The technical features in many embodiments can also be used interchangeably. Based on the technical principles of the present invention, those skilled in the art can recombine the technical solutions described in the above embodiments or simply replace some of the components therein with similar technologies. As long as they are based on the technical principles of the present invention, they are within the scope of protection required by the present invention.
