Abstract
The utility model discloses a spherical urban light rail pedestal, belonging to the technical field of bridge pedestals. The spherical urban light rail pedestal has the following main technical characteristics: the spherical urban light rail pedestal comprises an upper pendulum and a lower pendulum; wherein, the bottom of the upper pendulum is a convex surface; the top of the lower pendulum is a concave surface, which is matched with the convex surface; a polyfluortetraethylene board is arranged between the upper and the lower pendulums; the convex surface is provided with a stainless steel plate or plated with a hard chrome layer; a seal ring is arranged between the lower and the upper pendulums; and fixing bolts for the lower and the upper pendulums are arranged in pair. Since the prior separated upper and middle pedestal plates are substituted by the integrated upper pendulum adopted by the spherical urban light rail pedestal, the whole structure is simple, rotation is flexible, mounting is convenient, and material can be saved. The arranged seal ring has a sealing function as well as an automatic cleaning function. Since the fixing bolts for the lower and the upper pendulums are arranged in pair, the pedestal has a good anti-shock property.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of urban light rail spherical bearing.
Background technology
In bridge construction, horizontal movement that produces for adaptive temperature variation etc. and corner, vibration damping demand need to install bridge pad and carry out the horizontal force that transmits on pressure-bearing and the transfer beams.The spherical bearing of current use, its structure comprises upper base plate, middle seat board and following seat board, middle seat board bottom is provided with convex surface under the ball crown type, top is the plane, following seat board top is provided with the concave surface that is complementary with following convex surface, the upper base plate bottom is the plane, is respectively arranged with the friction pair that stainless steel slide plate and tetrafluoro slide plate constitute between upper base plate, following seat board and middle seat board.Spherical bearing is divided into fixed bearing, vertical or horizontal bearing and bi-directional movable bearing, and the upper base plate of fixed bearing and middle seat board adopt two body structures, waste material not only, and rotate dumbly, trouble is installed.
The utility model content
Problem to be solved in the utility model just provides a kind of fixed urban light rail spherical bearing flexible, easy for installation that rotates.
For solving the problems of the technologies described above, the technical scheme that the utility model urban light rail spherical bearing adopts is: comprise that put for going up of convex surface the bottom and the top is the bottom of concave surface, described convex surface and concave surface are complementary, and are provided with polyfluortetraethylene plate between the last pendulum and the bottom.
Its additional technical feature is: described convex surface is provided with corrosion resistant plate or is coated with hard chromium layers; Be provided with sealing ring between the described bottom and last pendulum; The set bolt of the described bottom and last pendulum is provided with in pairs.
Urban light rail spherical bearing provided by the utility model, compared with prior art, with the upper base plate and the middle seat board that pendulum has replaced original two bodies of going up of one, overall structure is simple, rotates flexibly, and is easy for installation, saves raw material.And the bottom and go up and to be provided with sealing ring between pendulum can seal, and when last pendulum was swung, sealing ring was to the corrosion resistant plate of convex surface setting or be coated with hard chromium layers and play cleaning action.The set bolt of the bottom and last pendulum is provided with in pairs, then makes bearing have good anti-seismic performance.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model urban light rail spherical bearing;
Fig. 2 is the another kind of structural representation of urban light rail spherical bearing.
The specific embodiment
Be described in further details below in conjunction with the structure of accompanying drawing urban light rail spherical bearing provided by the utility model.
As shown in Figure 1, urban light rail spherical bearing provided by the utility model comprises the pendulum 1 and the bottom 2, the bottom of last pendulum 1 is a convex surface 3, the top of the bottom 2 is a concave surface 4, convex surface 3 and concave surface 4 are complementary, 2 in the last pendulum 1 and the bottom are provided with polyfluortetraethylene plate 5 and sealing ring 6, and convex surface 3 is provided with corrosion resistant plate or is coated with hard chromium layers 7.As shown in Figure 2, the set bolt 8 of the bottom 1 and last pendulum 2 is provided with in pairs.
When using, on put 1 convex surface 3 and on the concave surface 4 of the bottom 2, swing simple in structure because the bearing overall structure is made of the last pendulum 1 and the bottom 2, rotate flexibly, easy for installation, the saving raw material.And sealing ring 6 is set, and can seal, when 1 swing of last pendulum, the corrosion resistant plate that 6 pairs of convex surfaces of sealing ring 3 are provided with or be coated with hard chromium layers 7 and play cleaning action.The set bolt 8 of the bottom 1 and last pendulum 2 is provided with in pairs, then makes bearing have good anti-seismic performance.
Claims (4)
