Description
Technical Field
The invention relates to the technical field of elevator equipment, in particular to a vibration isolation guide rail bracket device.
Background
When the elevator car runs in the elevator well, vibration on the guide rail can be transmitted to the well wall body through the guide rail bracket. In order to ensure safety, the guide rail is prevented from being deformed too much, the traditional guide rail bracket is of a rigid structure and is directly and rigidly connected with the well wall, and vibration on the guide rail side is directly transmitted to the well wall through the guide rail bracket, and vibration and noise in a resident room are caused through transmission of a building structure.
In order to reduce the vibration of the guide rail, an elastic element is added between the guide rail bracket and the wall body or between the guide rail bracket and the guide rail in a traditional way so as to reduce the transmission of the normal vibration of the wall surface. In order to obtain a good vibration isolation effect, an elastic member with smaller rigidity is generally required. However, due to the existence of the elastic piece, the connection rigidity of the guide rail and the wall body is weakened, so that the guide rail generates obvious displacement in the stress direction, if related limiting measures are lacked, guide shoes are easily derailed and the guide rail falls under extreme working conditions such as burning of the elastic piece caused by earthquake, safety tongs action or fire, and personal safety of passengers and safety of building structures are threatened.
According to the requirements of 5.7.6 permitted deformation in passenger and freight elevators, part 1 of GB 7588.1-201X safety Specification for manufacturing and installing elevators, the maximum permitted deformation for calculation of the T-shaped guide rail and its fixed parts (e.g. guide rail brackets, partition beams, etc.) is a) 10mm in both directions for the car, counterweight (or counterweight) guide rail provided with safety tongs, and for the counterweight (or counterweight) guide rail not provided with safety tongs, when the safety tongs are actuated. Therefore, in order to ensure the safety shape, it is necessary to add a safety limiting device when designing the vibration isolation guide rail bracket device.
In addition, the vibration isolation plate in the middle of the traditional vibration isolation guide rail bracket usually adopts a flat plate structure, exciting force transmitted from the guide rail side acts on the upper section and the lower section of the vibration isolation plate fixedly connected with the upper guide rail connecting plate and the lower guide rail connecting plate, and the reaction force of the wall side bracket to the vibration isolation plate acts on the middle of the vibration isolation plate, so that the vibration isolation plate is subjected to bending moment action. Because the vibration isolation plate of the flat plate structure has poor bending resistance and large middle deformation, the vibration isolation member is extremely easy to be compressed locally, so that the vibration isolation effect is poor and even fails.

Further, as a preferred embodiment, the side surfaces of the guide rails of the vertical structures at both ends of the vibration isolation plate 12 are vibration isolation plate negative Y-direction limit fit planes 17, the side surface of the hoistway of the vertical structure portion 30 in the middle of the vibration isolation plate 12 is vibration isolation plate positive Y-direction limit fit planes 19, and when the vibration isolation plate is mounted, the distance between the vibration isolation plate positive Y-direction limit fit planes 19 and the wall side bracket positive Y-direction limit planes 18, and the distance between the vibration isolation plate negative Y-direction limit fit planes 17 and the wall side bracket negative Y-direction limit planes 16 are dy, so as to prevent the vibration isolation plate 12 from being displaced or deformed greatly in the ±y directions.
Further, as a preferred embodiment, the end surfaces on both sides of the intermediate structure of the vibration isolation plate 12 are a negative X-direction limit fit plane 21 and a positive X-direction limit fit plane 26 of the vibration isolation plate, and when the vibration isolation plate is mounted, the distance between the negative X-direction limit fit 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 fit 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, so as to prevent the vibration isolation plate 12 from being greatly displaced or deformed in the + -X direction.
Further, as a preferred embodiment, the limit distances dx, dy and dz of the vibration isolation guide rail bracket device are set according to the requirements of allowable deformation of the guide rail in the national standard, and different limit distances are calculated and determined according to different intensities of the selected guide rails in the actual project.
Since the vibration of the hoistway wall is mainly in the Y direction, which causes room noise, the vibration damping effect of the Y-directional vibration damping material of the vibration damping plate 12 is to be improved as much as possible. In order to improve the vibration isolation effect of the vibration isolation material, the rigidity of the vibration isolation material needs to be reduced, but the too small rigidity can cause that the positive Y-direction limit fit plane 19 of the vibration isolation plate is directly pressed to the positive Y-direction limit plane 18 of the wall side bracket or the negative Y-direction limit fit plane 17 of the vibration isolation plate is directly pressed to the negative Y-direction limit plane 16 of the wall side bracket when the elevator runs, so that the vibration isolation effect of the Y-direction vibration isolation material is invalid. In order to solve the above problems, the y-direction elastic vibration insulating material should be made to have a variable stiffness so that it has a low stiffness with a small compression amount, and its stiffness can be rapidly increased with an increase in the compression amount.
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 against the wall side bracket rear side plate 9, and at the same time, the vibration isolation plate 12 compresses the rear side ladder-shaped elastic vibration isolation material 29 stuck on the wall side bracket rear side plate 9, at this time, the rigidity of the elastic vibration isolation material is the equivalent rigidity of the vibration isolation plate 12 after the combination of the elastic vibration isolation material 13 against the wall side bracket rear side plate 9 and the rear side ladder-shaped elastic vibration isolation material 29, since the rear side ladder-shaped elastic vibration isolation material 29 is trapezoidal, the rigidity also rapidly increases with the increase of the compression amount, thereby resulting in the rapid increase of the equivalent rigidity of the positive Y-direction elastic vibration isolation material, and conversely, when the vibration isolation plate 12 vibrates in the negative Y direction, the vibration isolation plate 12 compresses the front side ladder-shaped elastic vibration isolation material 28 stuck on the wall side bracket front side plate upper side plate 7, at this time, the rigidity of the elastic vibration isolation plate 12 compresses the equivalent rigidity of the vibration isolation material 13 against the wall side bracket front side plate 6 and the front side ladder-shaped elastic vibration isolation material 28 after the combination, and the equivalent rigidity of the front side ladder-shaped elastic vibration isolation material 28 rapidly increases with the rapid increase of the compression amount, thereby resulting in the rapid increase of the equivalent rigidity of the vibration isolation material.
