The specific embodiment
Be described further below in conjunction with structure and the principle of accompanying drawing to height-adjustable anti-pulling bearing provided by the utility model.
As shown in Figure 1, the movable upper base plate 1 that comprises of height-adjustable anti-pulling bearing provided by the utility model, spherical crown plate 2, middle liner plate 3, lower seat board 4, be provided with plane stainless steel plate 5 and plane wearing plate 6 between upper base plate 1 and the spherical crown liner plate 2, be provided with sphere corrosion resistant plate 7 and sphere wearing plate 8 between spherical crown plate 2 and the middle liner plate 3, be provided with sealing ring 9 between middle liner plate 3 and the lower seat board 4, the lower inside of upper base plate 1 is provided with drag hook 10, the upper outside of lower seat board 4 is provided with the lower drag hook 11 that is complementary with upper drag hook 10, upper drag hook 10 and 11 of lower drag hooks are provided with regulating block 12, the upper surface of regulating block 12 is provided with flexible dielectric layer 13, and the side of lower seat board 4 is provided with heightens passage 14.As shown in Figure 2, regulating block 12 is provided with dovetail wing 15.As shown in Figure 3, the side of upper drag hook 10 is provided with dovetail groove 16.As shown in Figure 4, the end face of upper drag hook 10 is provided with dovetail groove 16.As shown in Figure 5, the bottom surface of middle liner plate 3 is provided with groove 17.As shown in Figure 6, lower seat board 4 sides are provided with and heighten passage 14.
As shown in Figure 7, the fixed upper base plate 1 that comprises of the utility model height-adjustable anti-pulling bearing, spherical crown plate 2, middle liner plate 3, lower seat board 4, be provided with plane stainless steel plate 5 and plane wearing plate 6 between upper base plate 1 and the spherical crown liner plate 2, be provided with sphere corrosion resistant plate 7 and sphere wearing plate 8 between spherical crown plate 2 and the middle liner plate 3, be provided with sealing ring 9 between middle liner plate 3 and the lower seat board 4, the lower inside of upper base plate 1 is provided with drag hook 10, the upper outside of lower seat board 4 is provided with the lower drag hook 11 that is complementary with upper drag hook 10, upper drag hook 10 and 11 of lower drag hooks are provided with regulating block 12, the upper surface of regulating block 12 is provided with flexible dielectric layer 13, and the side of lower seat board 4 is provided with heightens passage 14.As shown in Figure 8, the side of upper drag hook 10 is provided with dovetail groove 16.As shown in Figure 9, regulating block 12 is provided with dovetail wing 15.As shown in figure 10, lower seat board 4 sides are provided with and heighten passage 14.
Height-adjustable anti-pulling bearing provided by the utility model, it is identical with common bearing when bridge is normally runed, can satisfy the functions such as the required bearing capacity of bridge, horizontal movement, corner, when being subjected to the extraneous factor bearing to bear vertical tension, upper drag hook 10 acts on by regulating block 12 with lower drag hook 11, by flexible dielectric layer 13 compressive strains of regulating block 12 upper surfaces, reduce pulling force to the impact of upper drag hook 10 with lower drag hook 11, prolong the application life of bearing.
