Abstract
The utility model discloses a rotating sleeve type spherical steel support for a railway bridge, belonging to the technical field of bridge supports. The utility model is mainly and technically characterized in that the rotating sleeve type ball steel support comprises an upper seat plate, a spherical crown lining plate and a lower seat plate, a plane sliding plate is arranged between the upper seat plate and the spherical crown lining plate, a spherical sliding plate is arranged between the spherical crown lining plate and the lower seat plate, a rotating sleeve is arranged between the upper seat plate and the lower seat plate, the internal part of the rotating sleeve is circular and the external part of the rotating sleeve is square, and a pressing plate used to support the rotating sleeve is arranged at the bottom of the upper seat plate. The upper seat plate is not in direct contact with the lower seat plate. The rotating sleeve is only placed on the pressing plate and is not fixed with the upper seat plate and the lower seat plate. When in turning the angle, after the spherical crown lining plate rotates, the upper seat plate drives the rotating sleeve to rotate, the rotating sleeve and the friction surface of the lower seat plate are of a concave arc surface and a convex arc surface matched with the concave arc surface, and no acting force is produced between the upper seat plate and the lower seat plate, so no damages are caused and the service life of the support is prolonged.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of railroad bridge with rotating the shell type ball shaped steel bearing.
Background technology
In bridge construction, horizontal movement that produces for adaptive temperature variation etc. and corner, shock attenuation needs need erection support to carry out the horizontal force that transmits on pressure-bearing and the transfer beams.The spherical bearing of current use, its structure comprise upper base plate, spherical crown liner plate and following seat board, are provided with the plane slide plate between upper base plate and spherical crown liner plate, are provided with the sphere slide plate between spherical crown liner plate and following seat board.In the use, finish corner and displacement by the gap between upper base plate and the following seat board.Upper base plate forms friction pair with following seat board side during displacement.During corner, after the spherical crown liner plate rotated, upper base plate formed line with the rubbing surface contact position of following seat board side and contacts, and has increased contact surface, and the contact position of upper base plate and following seat board is stressed to be easy to generate destruction, thus shortening bearing application life.
The utility model content
That problem to be solved in the utility model contact position of upper base plate and following seat board when providing a kind of corner is difficult for is stressed, the railroad bridge of long service life is with rotation shell type ball shaped steel bearing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise upper base plate, spherical crown liner plate and following seat board, be provided with the plane slide plate between upper base plate and spherical crown liner plate, be provided with the sphere slide plate between spherical crown liner plate and following seat board, the turning set of circle foreign side in being provided with between described upper base plate and following seat board, the bottom of upper base plate is provided with the pressing plate that is used for holding turning set.
Its additional technical feature is: be provided with the friction pair that corrosion resistant plate and ultra-high molecular weight polyethylene board constitute between the lateral surface of described turning set and the medial surface of upper base plate; Be provided with the friction pair that corrosion resistant plate and ultra-high molecular weight polyethylene board constitute between described turning set and pressing plate; The medial surface of described turning set is an inner concave arc surface, and the lateral surface of following seat board is the outer convex globoidal that is complementary with inner concave arc surface.
Railroad bridge provided by the utility model compared with prior art, is provided with the turning set of interior round foreign side with rotating the shell type ball shaped steel bearing between upper base plate and following seat board, the bottom of upper base plate is provided with the pressing plate that is used for holding turning set.Like this, upper base plate does not directly contact with following seat board, and turning set just is placed on the pressing plate, does not fix with upper base plate and following seat board.Between the lateral surface by turning set during displacement and the medial surface of upper base plate, the corrosion resistant plate that is provided with respectively between turning set and pressing plate and the friction pair of ultra-high molecular weight polyethylene board formation.During corner, after the spherical crown liner plate rotated, upper base plate drove turning set and rotates, turning set is inner concave arc surface and the outer convex globoidal that is complementary with the rubbing surface of following seat board, do not produce active force between upper base plate and following seat board, can not produce destruction, thereby prolong bearing application life.
Description of drawings
Fig. 1 is the structural representation of the utility model railroad bridge with rotation shell type ball shaped steel bearing;
Fig. 2 is the structural representation of turning set.
The specific embodiment
Below in conjunction with accompanying drawing railroad bridge provided by the utility model is described in further details with the structure and the principle of rotating the shell type ball shaped steel bearing.
As shown in Figure 1, railroad bridge provided by the utility model comprises upper base plate 1 with rotating the shell type ball shaped steel bearing, spherical crown liner plate 2 and following seat board 3,2 of upper base plate 1 and spherical crown liner plates are provided with plane slide plate 4, spherical crown liner plate 2 and 3 of following seat boards are provided with sphere slide plate 5, upper base plate 1 and 3 of following seat boards are provided with turning set 6, the bottom of upper base plate 1 is provided with the pressing plate 7 that is used for holding turning set 6, be provided with the friction pair that corrosion resistant plate 8 and ultra-high molecular weight polyethylene board 9 constitute between the medial surface of the lateral surface of turning set 6 and upper base plate 1, certainly, 7 of turning set 6 and pressing plates also can be provided with the friction pair of corrosion resistant plate 8 and ultra-high molecular weight polyethylene board 9 formations, the medial surface of turning set 6 is an inner concave arc surface 10, and the lateral surface of following seat board 3 is the outer convex globoidal 11 that is complementary with inner concave arc surface 10.As shown in Figure 2, circle foreign side in the turning set 6.
Railroad bridge provided by the utility model is with rotating the shell type ball shaped steel bearing, and upper base plate 1 does not directly contact with following seat board 3, and turning set 6 just is placed on the pressing plate 7, and is unfixing with upper base plate 1 and following seat board 3.Between the lateral surface by turning set 6 during displacement and the medial surface of upper base plate 1, the friction pair of 7 corrosion resistant plates that are provided with respectively 8 of turning set 6 and pressing plate and ultra-high molecular weight polyethylene board 9 formations.During corner, after spherical crown liner plate 2 rotated, upper base plate 1 drove turning set 6 and rotates, turning set 6 is inner concave arc surface 10 and the outer convex globoidal 11 that is complementary with the rubbing surface of following seat board 3, upper base plate 1 and 3 generations of following seat board not active force, can not produce destruction, thereby prolong bearing application life.
