Description
Technical field
The invention belongs to bridge structure or technical field of buildings, a kind of stepless height-regulating structure of straddle-type rail beam bearing.
Background technology
Cross-saddle single-track traffic is a kind of new model of modern city fast railway multilevel traffic, with noise is low, climbs
Slope ability is strong, radius of turn is small, rapid and convenient, takes up an area less, low cost, is not limited by landform and many excellent beneficial to environmental protection etc.
Point, it is a new trend of future city track traffic development.
Straddle-seat type single traffic rail beam is as two-way deflection component, except bearing train vertical load and lateral load（From
Mental and physical efforts, wind-force etc.）Effect is outer, also subject to larger torsion load, while the track also as train driving.Straddle-type track girder
Important component of the bearing as straddle-seat type single traffic rail beam, it is to ensure that straddle-seat type single traffic rail beam works orderly
The key point of effect.
Due to track of the track girder as train driving, the elevation of track girder orbital plane should remain at what design allowed
In the range of, track girder orbital plane settles the orbital plane elevation drawn in construction or during runing to be only had beyond design allowed band
It is adjusted by rail beam bearing.Therefore, straddle-type rail beam bearing except should have bear vertical load, horizontal loading,
It is vertical to draw load, torsion load and adapt to beam-ends deformation（Displacement, rotation）Outside, should also have vertical height regulatory function.
Current existing straddle-type monorail track traffic PC track girders employ the PC rails with articulated structure with bottom pier
Road beam cast steel supporter, as shown in Figure 4,5.This PC track girders cast steel supporter mainly by upper pendulum, hinge, dowel, the bottom, base,
Cam, anchor case and dowel composition.
The height regulating function of existing PC track girders cast steel supporter is that the mode that billet is filled between seat board and cam is carried out
Heighten, but there is also can not realize that stepless height-regulating, multi-layer gasket stack to be also easy to produce the mutual changing of the relative positions due to shaking in actual applications
The shortcomings of, it is unfavorable for the installation and later maintenance of bearing.
The content of the invention

To realize above-mentioned technical purpose, used technical scheme is：A kind of straddle-type rail beam bearing stepless height-regulating knot
Structure, it is arranged between lower seat board and bottom plate, including height regulation stud and the height that height regulation is carried out to height regulation stud
Spanner is adjusted, height regulation stud mounting hole A is opened up in lower seat board bottom, lower seat is provided with height regulation stud mounting hole A
Plate highly adjusts screw thread, and on bottom plate top, respective heights regulation stud mounting hole A opens up height regulation stud mounting hole B, height
Bottom plate heights regulation screw thread is provided with regulation stud mounting hole B, is respectively equipped with the both ends of height regulation stud high with lower seat board
The trapezoidal motion thread that degree regulation screw thread and bottom plate heights regulation screw thread match, both ends threaded engagement are in opposite direction.
Present invention additionally comprises the anti-rotation holding screw locked to height regulation stud.
The both sides of lower seat board and bottom plate of the present invention are respectively equipped with inclination prevention structure.
Inclination prevention structure of the present invention is provided with L-shaped anti-dumping plate, is offered on lower seat board vertical with anti-dumping plate
The equal lower seat board anti-dumping groove of plate width, the bottom plate anti-dumping groove to match with anti-dumping plate transverse plate, anti-dumping plate are offered in bottom plate
It is bolted in lower seat board anti-dumping groove and bottom plate anti-dumping groove.
The section of bottom plate anti-dumping groove of the present invention is inverted trapezoidal.
The present invention beneficial effect be：By the present invention, the stepless height regulating function of straddle-type rail beam bearing, Ke Yiyou are realized
Effect improves the security reliability and installation, the convenience of later maintenance of seat structure stress, and present invention accomplishes straddle-type
Rail beam bearing to the demand of stepless height regulating function, overcome existing PC track girders cast steel supporter existing for shortcomings and deficiencies, carry
The high convenience of straddle-seat type single traffic rail beam beam face elevation regulation.
