Description
Technical field
The present invention relates to bridge or construction engineering technical field, more particularly to a kind of stepless height-regulating spherical bearing.
Background technology
Large-span arch bridge can cause the elongation and shortening of arch due to the change of temperature, so as to cause the height of arch bridge bridge floor
Change, reduce the ride comfort of bridge floor.In order to ensure the comfortableness of bullet train, generally use drops when train passes through arch bridge
The mode of speed.Arch bridge bridge elevation can vary with temperature daily, in order to control the change of bridge elevation just to need one kind being capable of root
The bearing of height is adjusted accordingly according to bridge elevation change.
The height-adjustable supports scheme used both at home and abroad at present has backing plate to heighten, spiral is heightened, voussoir is heightened and adjusted with pressure injection rubber
It is high 4 kinds.
（1）Backing plate heightens mode
It is by adding steel at bearing top, bottom plate that bearing most widely used at present, that construction most convenient is feasible, which heightens one of mode,
Backing plate, specific configuration map Fig. 1.When needing to be heightened, the steel of beam body of first jack-uping, then thickness needed for addition
Plate, so as to realize the purpose heightened.
（2）Spiral heightens mode
The bearing of such a form adds larger trapezoidal thread, and after being heightened with screw thread, between mud jacking filling up and down spiral
Space.Within the specific limits, the stepless changing of arbitrary height can be achieved, and Bidirectional stepless can adjust up and down as needed, and
Adjustment can be repeated several times.Jack back timber is also required to during heightening.Spiral height-adjustable supports specific configuration is shown in Fig. 2.
（3）Voussoir heightens mode
Voussoir, which heightens mode, to be heightened by adding one group of gad block above the top plate of bearing.Voussoir height-adjustable supports have
Body structural map is shown in Fig. 3.
（4）Pressure injection rubber heightens mode
Pressure injection rubber height-adjustable supports are provided with mud jacking pipeline on base-plate, can improve pressure-bearing rubber in bearing by pressure injection rubber
The thickness of glue, reach the effect of adjustment height of support.Pressure injection rubber heightens pot bearing specific configuration and sees Fig. 4.
Pressure injection rubber is heightened to be not required to separately set jack back timber when mode is heightened, and by setting multiple tracks pressure injection hole mud jacking, is utilized
Bearing realizes the stepless height-regulating of bearing in itself.Can be allowed by bearing vertical bearing capacity limit value, the amount of heightening and rubber bearing plate should
The grouting pipe slip casting of different maximum crushing stress values is chosen in power control.
Heighten mode for above-mentioned four kinds to belong to passively heighten category, be to meet or exceed a certain limit in railroad bridge deformation
Value, and then when influence Track regularity, just bearing is heightened by railway maintenance Departmental organization relevant unit, existed bright
Aobvious hysteresis quality and uncertainty.Moreover, heightening length duty cycle, efficiency is low, it is necessary to suspend traffic or select to run in circuit
Operation in window phase, construction cost are high.
The content of the invention

Double helix end face structure A601 and inside and outside double helix end face structure B602 are in screw thread mated condition.Conversely, when that need to turn down, it is interior
Outer double helix end face structure A601 is jacked up, and double helix Contact Pair is not subject to vertical load, inside and outside double helix end face structure B602
Being jacked up with the backwards rotation of worm gear 7, then by inside and outside double helix end face structure A601, double helix Contact Pair is not subject to vertical load,
Inside and outside double helix end face structure A601 is put down, and reaches the purpose turned down.
To reduce friction of the double helix Contact Pair 6 when in use between bedplate, in inside and outside double helix end face structure
Pivoting friction pair is set between B602 lower surface and the upper surface of bedplate 12.
Horizontal Worm and worm-wheel gearing is made up of servomotor 9, worm screw 8 and worm gear 7, and worm screw 8 connects with servomotor 9
Connect, and the setting that is meshed with worm gear 7, worm gear 7 is set in inside and outside double helix end face structure B602 outside, and with inside and outside double helix
End face structure B602 is coaxially disposed, and is connected by bolt, can be by being calculated by, the helical pitch of screw rod and inside and outside double helix end face
Relation after structure B602 rotations between helical pitch, and the hoisting depth or height of drop of lower seat board, then whole device is set
Put.
Guider is provided between support body system and bedplate, support body system is by guider in Vertical Square
To moving up and down, guider may include following three kinds of forms：
Multiple guide pillar hole A24 are opened up on the lower surface of described support body system, the bedplate 12 in guide pillar hole A24 lower section
On be correspondingly provided with guide pillar hole B42, guide pillar 13 is provided with guide pillar hole A24 and guide pillar hole B42, the length of guide pillar 13 is more than guide pillar hole
Maximum spacing between A24 and guide pillar hole B42.
