Description
Technical field
The utility model relates to bridge pad, the particularly a kind of anti-pulling spherical bearing that can resist vertical pulling force.
Background technology
The anti-pulling spherical bearing is a kind of novel bridge bearing that on the basis of ball shaped steel bearing, grows up.It has increased the anti-pulling device, makes bearing on the original basis that can bear vertical pressure, horizontal force, can resist vertical pulling force.In existing unidirectional activity anti-pulling bearing, directly contact the transmission horizontal force by the upper bracket plate with lower support plate, contact surface is provided with slide plate and corrosion resistant plate to adapt to the support displacement requirement.When beam-ends rotated, upper bracket plate and lower support plate be the keeping parallelism state no longer, made contacting by face contact becoming line of slide plate and corrosion resistant plate contact, and caused sled surface inhomogeneous stressed, caused squeeze and destroy.In addition, existing anti-pulling bearing anti-pulling plate is the plane with a seat board contact surface, can't adapt to the needs of corner displacement.Can't adapt to corner reciprocal when bearing is in tension state, the shear stress that anti-pulling base-plate parts bear, the uplift force that anchoring piece is born all no longer are equally distributed, thereby cause the parts local pressure that the situation that stress exceeds standard appears in a certain angle point.
The utility model content
The utility model technical problem to be solved provides a kind of bridge anti-pulling spherical bearing, has that level angle is big, characteristics of high-bearing capacity and abrasion performance.
It is following that the utility model solves the technical scheme that its technical problem adopted:
The anti-pulling spherical bearing of the utility model; Comprise upper bracket plate, lower support plate; Its characteristic is: lower support plate is provided with the spherical crown liner plate between said upper bracket plate, the lower support plate, and spherical crown liner plate and upper bracket plate, lower support plate form first friction pair, second friction pair respectively; Upper bracket plate, lower support plate have last convex shoulder structure, following convex shoulder structure along bridge respectively to both sides, fixedly install the anti-pulling plate respectively in the lower support plate both sides; Anti-pulling plate cross section is flute profile, and its upper open end, lower open end are stuck in outside convex shoulder structure, the following convex shoulder structure, have vertical gap between upper open end and the last convex shoulder structure.
The convex shoulder structure facing surfaces is curved on the upper open end of said anti-pulling plate and the upper bracket plate.
The beneficial effect of the utility model is; When bearing rotated, lower support plate closely contacted with the spherical crown shape lower arcuate surface of spherical crown liner plate all the time, and spherical crown liner plate and upper bracket plate remain plane contact; Level angle is big; Stressed even, can not cause the broken ring of extruding, thereby prolong the application life of bearing; Anti-pulling plate and upper bracket plate contact surface adopt cambered surface, have guaranteed that bearing is drawn all even rotation good; The transmission of power is born by bottom contact surface and lock bolt jointly between anti-pulling plate and the lower support plate, and bearing is safer, and the vertical pulling force that can bear is bigger.
Description of drawings
This manual comprises like next width of cloth accompanying drawing:
Fig. 1 is the structural representation of the utility model anti-pulling spherical bearing.
Component names shown in the figure and pairing mark: upper bracket plate 10, last convex shoulder 10a, corrosion resistant plate 11, lower support plate 20, following convex shoulder 20a, spherical crown liner plate 30, slide plate 31, wearing plate 32, anti-pulling plate 40, lock bolt 41.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
With reference to Fig. 1, the anti-pulling spherical bearing of the utility model comprises upper bracket plate 10, lower support plate 20.Lower support plate 20 is provided with spherical crown liner plate 30 between said upper bracket plate 10, the lower support plate 20, and spherical crown liner plate 30 forms first friction pair, second friction pair respectively with upper bracket plate 10, lower support plate 20.Said first friction pair is made up of with the corrosion resistant plate 11 that is adhesively fixed on upper bracket plate 10 bottom surfaces the slide plate 31 of build-in in spherical crown liner plate 30 end faces.Said second friction pair is made up of in the wearing plate 32 of lower support plate 20 spherical crown shape arc top surfaces spherical crown liner plate 30 spherical crown shape lower arcuate surface and build-in.When bearing rotated, lower support plate 10 closely contacted with the spherical crown shape lower arcuate surface of spherical crown liner plate 30 all the time, and spherical crown liner plate 30 remains plane contact with upper bracket plate 10; Stressed even; Level angle is big, can not cause the broken ring of extruding, thereby prolongs the application life of bearing.
With reference to Fig. 1, upper bracket plate 10, lower support plate 20 have last convex shoulder structure 10a, following convex shoulder structure 20a along bridge respectively to both sides, fixedly install anti-pulling plate 40 respectively in lower support plate 20 both sides.Anti-pulling plate 40 cross sections are flute profile, and its upper open end, lower open end are stuck in outside convex shoulder structure 10a, the following convex shoulder structure 20a, have vertical gap between upper open end and the last convex shoulder structure 10a.The last convex shoulder structure 10a facing surfaces of the upper open end of said anti-pulling plate 40 and upper bracket plate 10 is curved, and anti-pulling plate 30 adopts cambered surface with upper bracket plate 10 contact surfaces, has guaranteed that bearing is drawn all even rotation good.The lock bolt 41 that said anti-pulling plate 40 is provided with through direction across bridge at interval is fixedly connected on the sidewall of 20 times convex shoulder structure 20a of lower support plate; The transmission of power is born by bottom contact surface and lock bolt 41 jointly between anti-pulling plate 30 and the lower support plate 20; Bearing is safer, and the vertical pulling force that can bear is bigger.
Spherical crown liner plate 30 adopts magnadure to make, and its density is little, and bearing weight is reduced greatly, and structural member adopts the Q345 hot rolled steel plate, has strengthened bearing holistic resistant behavior and reliability; Seat structure is lighter and handier than cast steel supporter, transports to bearing, installs and substitute to bring great convenience.Slide plate 31, wearing plate 3 adopt ultra-high molecular weight polyethylene (XLIDE) to make, and its line rate of wear and friction factor are littler, and the design surface pressure is bigger, longer service life.
