Description

Vibration isolation guide rail bracket device
Technical Field
The invention relates to the technical field of elevator equipment, in particular to a vibration isolation guide rail support device.
Background
When the elevator car runs in the elevator shaft, vibration on the guide rail can be transmitted to the shaft wall body through the guide rail bracket. In order to ensure safety and prevent the guide rail from deforming too much, the traditional guide rail bracket is of a rigid structure and is directly and rigidly connected with a well wall, vibration on the side of the guide rail is directly transmitted to the well wall through the guide rail bracket, and vibration and noise problems in a resident room are caused through transmission of a building structure.
In order to reduce the vibration of the guide rail, it is conventional to add an elastic member between the guide rail bracket and the wall or between the guide rail bracket and the guide rail to reduce the transmission of the normal vibration of the wall. In order to obtain better vibration isolation effect, an elastic member with lower rigidity is generally required to be selected. However, due to the existence of the elastic element, 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 a related limit measure is lacked, under the extreme working conditions of burning of the elastic element caused by earthquake, safety tongs action or fire, the guide rail is easy to derail and fall, and the personal safety of passengers and the safety of building structures are threatened.
According to section 1 of the GB 7588.1-201X Elevator manufacturing and installation safety Specification: the requirement of 5.7.6 allowable deformation in passenger elevator and freight elevator, the maximum calculation allowable deformation of T-shaped guide rail and its fixed parts (such as guide rail bracket, spacer beam, etc.) is: a) for a car and a counterweight (or counterweight) guide rail provided with safety tongs, when the safety tongs act, the length of the guide rail is 5mm in two directions; b) for the counterweight (or counterweight) guide rail without safety gear, 10mm in two directions. Therefore, in order to ensure the safety shape, a safety limiting device is required to be added when the vibration isolation guide rail bracket device is designed.
In addition, the vibration isolation plate in the middle of the traditional vibration isolation guide rail bracket usually adopts a flat plate structure, and excitation 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; the reaction force of the wall side support to the vibration isolation plate acts on the middle of the vibration isolation plate, so that the vibration isolation plate is subjected to the action of bending moment. Because the vibration isolation plate with the flat plate structure has poor bending resistance and large middle deformation, the vibration isolation piece is easy to be locally compressed, and the vibration isolation effect is poor or even fails.

Further, as a preferred embodiment, the middle of the "bow" shaped structure of the vibration isolation plate 12 includes a horizontal structure portion 31 and a vertical structure portion 30, wherein two ends of the vertical structure portion 30 are respectively connected to the two horizontal structure portions 31, and an included angle between the two horizontal structure portions 31 and the vertical structure portion 30 is an obtuse angle.
Further, as a preferred embodiment, the upper surface and the lower surface of the horizontal structure portion 31 in the middle of the vibration isolation plate 12 are the vibration isolation plate positive Z-direction limit matching plane 15 and the vibration isolation plate negative Z-direction limit matching plane 24, and when the vibration isolation plate is installed, the distance between the vibration isolation plate positive Z-direction limit matching plane 15 and the wall side bracket positive Z-direction limit plane 14 and the distance between the vibration isolation plate negative Z-direction limit matching plane 24 and the wall side bracket negative Z-direction limit plane 23 are controlled to be dz, so as to prevent the vibration isolation plate 12 from generating large displacement or deformation in the ± Z direction.
Further, as a preferred embodiment, the vertical structure rail side surfaces at the two ends of the vibration isolation plate 12 are vibration isolation plate negative Y-direction spacing matching planes 17, the hoistway side surface of the vertical structure part 30 in the middle of the vibration isolation plate 12 is vibration isolation plate positive Y-direction spacing matching plane 19, and when the vibration isolation plate is installed, the distance between the vibration isolation plate positive Y-direction spacing matching plane 19 and the wall side bracket positive Y-direction spacing plane 18 and the distance between the vibration isolation plate negative Y-direction spacing matching plane 17 and the wall side bracket negative Y-direction spacing plane 16 are controlled to be dy, so as to prevent the vibration isolation plate 12 from generating large displacement or deformation in the ± Y direction.
Further, as a preferred embodiment, the two side end surfaces of the middle structure of the vibration isolation plate 12 are a vibration isolation plate negative X-direction limit matching plane 21 and a vibration isolation plate positive X-direction limit matching plane 26, and when the vibration isolation plate is installed, the distance between the vibration isolation plate negative X-direction limit matching plane 21 and the wall side bracket negative X-direction limit plane 20 and the distance between the vibration isolation plate positive X-direction limit matching plane 26 and the wall side bracket positive X-direction limit plane 25 are controlled to be dx, so as to prevent the vibration isolation plate 12 from generating large displacement or deformation 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 requirement of national standards for allowable deformation of the guide rail, and different limit distances are calculated and determined according to the difference in strength of the guide rail selected in the actual project.
Since the Y-direction vibration is mainly a vibration causing the vibration of the hoistway wall and generating the house noise, the vibration isolation effect of the ± Y-direction vibration isolation material of the vibration isolation plate 12 is to be improved as much as possible. The rigidity of the vibration isolation material needs to be reduced in order to improve the vibration isolation effect of the vibration isolation material, but when the rigidity is too low, the positive Y-direction limiting matching plane 19 of the vibration isolation plate directly presses the positive Y-direction limiting plane 18 of the wall side support during the operation of the elevator or the negative Y-direction limiting matching plane 17 of the vibration isolation plate directly presses the negative Y-direction limiting plane 16 of the wall side support, so that the vibration isolation effect of the Y-direction vibration isolation material fails. In order to solve the above problems, the y-direction elastic vibration-isolating material should have a variable stiffness so that it has a lower stiffness with a small amount of compression, and the stiffness thereof can be rapidly increased as the amount of compression increases.
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 abutting against the wall side support rear side plate 9, and at the same time, the vibration isolation plate 12 compresses the rear side trapezoidal elastic vibration isolation material 29 attached to the rear side plate upper limiting plate 10, and the rigidity of the elastic vibration isolation material is the equivalent rigidity of the combination of the elastic vibration isolation material 13 abutting against the wall side support rear side plate 9 and the rear side trapezoidal elastic vibration isolation material 29 compressed by the vibration isolation plate 12, and since the rear side trapezoidal elastic vibration isolation material 29 is trapezoidal, the rigidity thereof is also rapidly increased with the increase of the compression amount, so that the equivalent rigidity of the positive Y direction elastic vibration isolation material is rapidly increased; in contrast, when the vibration isolation plate 12 vibrates in the negative Y direction, the vibration isolation plate 12 compresses the elastic vibration isolation material 13 abutting against the wall side bracket front side plate 6, and the vibration isolation plate 12 compresses the front side trapezoidal elastic vibration isolation material 28 attached to the front side plate upper limit plate 7, and at this time, the rigidity of the elastic vibration isolation material is the equivalent rigidity of the combination of the elastic vibration isolation material 13 abutting against the wall side bracket front side plate 6 and the front side trapezoidal elastic vibration isolation material 28 compressed by the vibration isolation plate 12, and since the front side trapezoidal elastic vibration isolation material 28 is trapezoidal, the rigidity thereof also increases rapidly with the increase of the compression amount, thereby causing the equivalent rigidity of the negative Y elastic vibration isolation material to increase rapidly.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
