Abstract
The utility model discloses a teflon plate rocker bearing, put floor, lower hem floor, dust cover, the lower hem, polyfluortetraethylene plate, corrosion resistant plate, end basin, stop gear on, including last pendulum. Go up the pendulum and put through the circular arc contact with the lower hem, go up that put and the lower hem will have floor support periphery will be equipped with the dust cover, the lower hem suitable bridge to having certain distance with end basin edge, lower hem bottom surface steel sheet is connected with polyfluortetraethylene plate, the stainless steel slide is connected with end basin, at horizontal bridge to there being stop gear. The utility model overcomes the rocker bearing displacement is less not enough, make rocker bearing can suitable bridge to having great displacement, messenger rocker bearing's application is more extensive.
Description
Technical field
This utility model relates to a kind of tetrafluoro plate rocker bearing, is mainly used on the railroad bridge of 20-32m.
Background technology
Before the sixties in 20th century, bridle iron is widely used on the bridge of China, and the bearing capacity of rocker bearing is strong, is mainly used on the railway bridge bearing of 20m-32m.The displacement of beam body be rotated by the bottom after push up, the displacement difference of bottom surface meet, the most often can not meet the needs of big displacement.
Utility model content
The purpose of this utility model is to overcome above-mentioned weak point, it is provided that a tetrafluoro plate rocker bearing, has more preferable displacement performance and rotating property.
The technical scheme that this utility model is used for achieving the above object is as follows: a kind of tetrafluoro plate rocker bearing includes pendulum, upper pendulum floor, bottom floor, dust cover, the bottom, polyfluortetraethylene plate, corrosion resistant plate, end basin, position-limit mechanism, it is characterized in that upper pendulum is contacted by concentric circular with the bottom, with politef slide bonding bottom the bottom, corrosion resistant plate bonds with end basin, is adapted to the displacement of bridge by the slip of corrosion resistant plate Yu polyfluortetraethylene plate.
Upper pendulum described in this utility model has circular groove, and the bottom is concentric with groove with upper pendulum contact position.
The floor of the upper pendulum described in this utility model is lower than upper pendulum.
The tapering of the bottom base plate described in this utility model is 0.5-0.7, and with politef slide bonding bottom the bottom, corrosion resistant plate bonds with end basin, and polyfluortetraethylene plate contacts with corrosion resistant plate.
Polyfluortetraethylene plate described in this utility model along bridge to being less than end basin length.
Rocker bearing described in this utility model meets bridge displacement requirement by the slip of polyfluortetraethylene plate Yu corrosion resistant plate.
Tetrafluoro plate rocker bearing described in this utility model, in direction across bridge limited location mechanism, stops the bottom in the displacement of direction across bridge.

Detailed description of the invention
Below in conjunction with the accompanying drawings the technical solution of the utility model is described further: as shown in Figure 1: include upper pendulum 1, upper pendulum floor 2, bottom floor 3, dust cover 4, the bottom 5, polyfluortetraethylene plate 6, corrosion resistant plate 7, end basin 8, position-limit mechanism 9.Upper pendulum 1 uses cast steel or Plate Welding to form, and the smoothness of its arc groove to ensure, the basal surface position of upper pendulum floor 2 will be in the lower section of upper pendulum, to ensure that the bottom 5 to ensure between 0.5-0.7 without departing from correct installation site, the tapering of the bottom 5 base plate.The bottom 5 along bridge to length be less than end basin 8 along bridge to length, make bearing the most arbitrarily to slide, position-limit mechanism be set at direction across bridge, limit the bearing displacement at direction across bridge.Polyfluortetraethylene plate 6 bonds with the bottom 5, and rustless steel slide plate 7 bonds with end basin 8, is met the displacement request of bearing by the slip of corrosion resistant plate 7 with polyfluortetraethylene plate 6.Support outer arranges dust cover 4.
