Technical field
The utility model relates to the bridge engineering parts, relates in particular to a kind of abrasion resistance ball shaped steel bearing that is used between bridge beam body and the bridge pier.
Background technology
Ball shaped steel bearing is contemporary bridge design, build requisite engineering part.Present domestic ball shaped steel bearing is made up of last anchor plate, end basin, piston piece and spherical crown liner plate usually.Be arranged at the bottom of spherical crown liner plate lower surface and the end basin basin that wearing plate is fixed on spherical crown liner plate lower surface between the inner surface, inner surface forms fastness at the bottom of wearing plate and the end basin basin.This structural iron bearing causes end basin planar dimension bigger because wearing plate is fixed on spherical crown liner plate lower surface, increases financial cost.
The utility model content
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, to propose a kind of bearing overall structure abrasion resistance ball shaped steel bearing little, in light weight, easy for installation, making it can improve installation effectiveness and installation accuracy.
The utility model adopts following technical scheme for achieving the above object: a kind of ball-type abrasion-resistant stee bearing, comprise anchor plate, end basin, piston piece and spherical crown liner plate, the upper end of described piston piece contacts with last anchor plate, the lower end is interior concave spherical surface, cooperate with the sphere of spherical crown liner plate upper end, spherical crown liner plate lower surface is the plane, be positioned at the bottom of the end basin basin on the inner surface, it is characterized in that being provided with wearing plate between the inner surface at the bottom of spherical crown liner plate lower surface and the end basin basin, this wearing plate is fixed at the bottom of the end basin basin on the inner surface.
Furtherly, described wearing plate can be embedded in the groove of inner surface at the bottom of the end basin basin.
In such scheme, be connected with chute by the line slideway that cooperatively interacts between the upper end of described piston piece and the last anchor plate lower end, between the upper surface of piston piece and the last anchor plate lower surface except that middle part line slideway and chute remainder be corresponding contact plane.
Furtherly, described line slideway is positioned at centre position, piston piece upper surface.
In such scheme, be corresponding contact plane between the upper surface of described piston piece and the last anchor plate lower surface, be provided with wearing plate between the contact plane of two correspondences.
Upward anchor plate of the present utility model and end basin are separately fixed on the anchorage rod iron that is embedded in bridge and the bridge pier concrete, are used for fixing bearing and transmit horizontal force.The external force of the utility model horizontal direction is directly passed to end basin by piston piece.Be applicable to fixed bearing, lateral type bearing and multi-orientation type bearing.
The utility model bearing overall structure is little, light weight, cost performance height, especially adopt and to be fixed in the scheme on the inner surface at the bottom of the end basin basin at the wearing plate between the inner surface at the bottom of spherical crown liner plate lower surface and the end basin basin, make the bearing lateral dimension to reduce, be convenient to install and regulate, be used for concrete bridge and steel bridge.
