Description

Technical Field

[0001] The present invention relates to the technical field of elevator equipment, and in particular to a vibration isolation guide rail bracket device. Background Art

[0002] As the elevator car travels within the elevator hoistway, vibrations from the guide rails are transmitted to the hoistway walls via the guide rail brackets. To ensure safety and prevent excessive guide rail deformation, traditional guide rail brackets are rigidly connected to the hoistway walls. This transfers vibrations from the guide rails directly to the hoistway walls through the guide rail brackets, and then through the building structure, causing vibration and noise problems within residents' homes.

[0003] To reduce guide rail vibration, the traditional approach is to add elastic elements between the guide rail bracket and the wall, or between the guide rail bracket and the guide rail, to reduce the transmission of normal vibration from the wall. To achieve optimal vibration isolation, elastic elements with low stiffness are typically used. However, the presence of these elastic elements weakens the rigidity of the guide rail-to-wall connection, causing the guide rail to significantly move in the direction of force. Without appropriate limiting measures, extreme operating conditions such as earthquakes, safety clamp activation, or fire that causes the elastic elements to burn can easily cause the guide shoe to derail and the guide rail to fall, threatening passenger safety and the safety of the building structure.

[0004] According to the requirements of Section 5.7.6 of the "GB 7588.1-201X Safety Code for Elevator Manufacturing and Installation," Part 1: Permissible Deformation for Passenger and Freight Elevators, the maximum calculated permissible deformation of T-shaped guide rails and their fixing components (such as guide rail brackets and partition beams) is: a) For car and counterweight (or balancing weight) guide rails equipped with safety clamps, when the safety clamp is activated, the maximum permissible deformation is 5mm in both directions; b) For counterweight (or balancing weight) guide rails without safety clamps, the maximum permissible deformation is 10mm in both directions. Therefore, to ensure safe deformation, it is necessary to add safety limit devices when designing the vibration isolation guide rail bracket system.

[0005] Furthermore, the vibration isolation plate in the center of a conventional vibration isolation guideway bracket often utilizes a flat plate structure. The excitation force from the guideway acts on the upper and lower sections of the plate, which are fixed to the upper and lower guideway connecting plates. The reaction force from the wall-side bracket acts on the center of the plate, subjecting it to a bending moment. Because the flat plate structure has poor bending resistance and significant deformation in the center, it is prone to localized compression of the isolation component, degrading or even failing the isolation effect.

During installation, the distance between the positive Z-direction limit matching plane 15 of the vibration isolation plate and the positive Z-direction limit matching plane 14 of the wall side bracket, and the distance between the negative Z-direction limit matching plane 24 of the vibration isolation plate and the negative Z-direction limit plane 23 of the wall side bracket are controlled to be dz to prevent the vibration isolation plate 12 from large displacement or deformation in the ±Z direction.

[0071] Furthermore, as a preferred embodiment, the side surfaces of the vertical structural guide rails at both ends of the vibration isolation plate 12 are the negative Y-direction limit matching plane 17 of the vibration isolation plate, and the shaft side surface of the vertical structural part 30 in the middle of the vibration isolation plate 12 is the positive Y-direction limit matching plane 19 of the vibration isolation plate. During installation, the distance between the positive Y-direction limit matching plane 19 of the vibration isolation plate and the positive Y-direction limit plane 18 of the wall side bracket, and the distance between the negative Y-direction limit matching plane 17 of the vibration isolation plate and the negative Y-direction limit plane 16 of the wall side bracket are controlled to be dy to prevent the vibration isolation plate 12 from large displacement or deformation in the ±Y direction.

[0072] Furthermore, as a preferred embodiment, the end faces on both sides of the middle structure of the vibration isolation plate 12 are the negative X-direction limit fitting plane 21 of the vibration isolation plate and the positive X-direction limit fitting plane 26 of the vibration isolation plate. During installation, the distance between the negative X-direction limit fitting plane 21 of the vibration isolation plate and the negative X-direction limit plane 20 of the wall side bracket, and the distance between the positive X-direction limit fitting plane 26 of the vibration isolation plate and the positive X-direction limit plane 25 of the wall side bracket are controlled to be dx to prevent the vibration isolation plate 12 from large displacement or deformation in the ±X direction.

[0073] Furthermore, as a preferred embodiment, the limit distances of the vibration isolation guide rail bracket device are set to dx, dy, and dz according to the requirements of the national standard for the allowable deformation of the guide rail. Different limit distances are calculated and determined according to the different strengths of the guide rails selected in the actual project.

[0074] Since the vibration in the y-direction is the main cause of the vibration of the shaft wall and the noise in the living room, the vibration isolation effect of the ±Y-direction vibration isolation material of the vibration isolation plate 12 should be increased as much as possible. In order to improve the vibration isolation effect of the vibration isolation material, the stiffness of the vibration isolation material needs to be reduced. However, if the stiffness is too low, the positive Y-direction limit matching plane 19 of the vibration isolation plate will be directly pressed against the positive Y-direction limit plane 18 of the wall side bracket, or the negative Y-direction limit matching plane 17 of the vibration isolation plate will be directly pressed against the negative Y-direction limit plane 16 of the wall side bracket when the elevator is running, thereby causing the vibration isolation effect of the Y-direction vibration isolation material to fail. In order to solve the above problem, the elastic vibration isolation material in the y-direction should have variable stiffness, so that it has lower stiffness under small compression, and its stiffness can increase rapidly with the increase of compression.

[0075] Specifically, when the vibration isolation plate 12 vibrates in the positive Y direction, the vibration isolation plate 12 compresses the elastic vibration isolation material 13 that is against the rear side plate 9 of the wall side bracket. At the same time, the vibration isolation plate 12 compresses the rear trapezoidal elastic vibration isolation material 29 attached to the upper limit plate 10 of the rear side plate. At this time, the stiffness of the elastic vibration isolation material is the equivalent stiffness of the combination of the elastic vibration isolation material 13 and the rear trapezoidal elastic vibration isolation material 29 that are against the rear side plate 9 of the wall side bracket compressed by the vibration isolation plate 12. Since the rear trapezoidal elastic vibration isolation material 29 is trapezoidal, its stiffness increases rapidly with the increase in compression, resulting in the rapid increase in the equivalent stiffness of the elastic vibration isolation material in the positive Y direction. Increase; Conversely, when the vibration isolation plate 12 vibrates in the negative Y direction, the vibration isolation plate 12 compresses the elastic vibration isolation material 13 that is against the front side plate 6 of the wall side bracket, and the vibration isolation plate 12 compresses the front trapezoidal elastic vibration isolation material 28 pasted on the upper limit plate 7 of the front side plate. At this time, the stiffness of the elastic vibration isolation material is the equivalent stiffness of the combination of the elastic vibration isolation material 13 and the front trapezoidal elastic vibration isolation material 28 compressed by the vibration isolation plate 12 and the front side trapezoidal elastic vibration isolation material 28. Since the front trapezoidal elastic vibration isolation material 28 is trapezoidal, its stiffness increases rapidly with the increase of compression, thereby causing the equivalent stiffness of the negative Y elastic vibration isolation material to increase rapidly.

For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
