Description

A kind of spherical bearing of variable slip mode

Technical field

The utility model belongs to technical field of bridge, more particularly to a kind of spherical bearing of variable slip mode.

Background technology

In Bridge Design, for bearing as critical piece, it carries passes to substructure by the load on bridge top, And meet the needs of rotation and the displacement of superstructure, bridge pad has hold-down support, slides laterally bearing, longitudinal sliding motion branch Seat, bidirectional sliding support, in bridge pad installation process, because construction reason often installs bearing glide direction installation site Mistake, changes the stress of bed rearrangement bridge, produces damage to bridge, or bearing, telescopic device etc. are damaged.

Utility model content

The purpose of this utility model is to disclose a kind of spherical bearing of variable slip mode easy to installation and maintenance.

Adopted the following technical scheme that to solve the above problems：

A kind of spherical bearing of variable slip mode, including upper base plate, intermediate, spherical crown plate and lower seat board, the bearing For ball-type inverted structure, the top of the lower part of upper base plate and lower seat board is respectively equipped with limiting plate, is set above intermediate with following Have wearing plate, be equipped with wearing plate below spherical crown plate, the lower part of upper base plate and the top of the contact surface of wearing plate and lower seat board with Hard chrome, the reduction friction coefficient of bigger are coated with the contact surface of wearing plate.

A kind of spherical bearing of above-mentioned variable slip mode, the limiting plate on upper base plate are removed, and only descending on seat board has Limiting plate, into sliding laterally bearing.

A kind of spherical bearing of above-mentioned variable slip mode, the limiting plate on lower seat board are removed, only had on upper base plate Limiting plate, into longitudinal sliding motion bearing.

A kind of spherical bearing of above-mentioned variable slip mode, upper and lower seat board limiting plate is all removed, into Bidirectional slide branch Seat.

The advantages of the utility model：The limiting plate of upper base plate and lower seat board is played a role and led at the same time when with hold-down support Fixation is played to bar collective effect；Removed when with upper base plate limiting plate when sliding laterally bearing；When with longitudinal sliding motion bearing When upper base plate limiting plate reinforce, lower seat board limiting plate is removed；The limiting plate of seat board up and down of bearing is all torn open when with Bidirectional slide Remove；Bearing is ball-type inverted structure, and performance is more stable, and when installation can disregard glide direction and be installed, thus solve because Repaired, repaired for the bearing setup error later stage.

Embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, including upper base plate 1, intermediate 2, spherical crown plate 3 and lower seat board 4, bearing For ball-type inverted structure, the top of the lower part of upper base plate 1 and lower seat board 4 is respectively equipped with limiting plate 61,61,71,72, upper base plate 1 Lower part and intermediate 2 contact position and the top of lower seat board 4 and the contact position of spherical crown plate 3 be coated with hard chrome plating, intermediate 2 it is upper Face and wearing plate 5 is arranged below, wearing plate is equipped with below spherical crown plate 3.

With reference to Fig. 3, Fig. 4, the limiting plate 61,62 on upper base plate 1 is removed, only descends the top of seat board 4 to be equipped with limiting plate 71st, 72, reform into and slide laterally bearing.

With reference to Fig. 5, Fig. 6, the top of lower seat board 4 is equipped with the dismounting of limiting plate 71,72, limiting plate 61 only on upper base plate 1, 62, reform into longitudinal sliding motion bearing.

Upper and lower seat board limiting plate is all removed, into bidirectional sliding support.Glide direction progress can be disregarded when so installing Installation, so as to solve because the bearing setup error later stage is repaired, repaired.
