Abstract
The utility model belongs to the technical field of bridge supports, and discloses a stepless heightening shock absorbing spherical support. The support is mainly technically characterized by comprising an upper seat plate, a middle seat plate, a spherical steel lining plate and a lower seat plate; a spherical friction pair is arranged between the middle seat plate and the spherical steel lining plate; a planar friction pair is arranged between the spherical steel lining plate and the lower seat plate; the bottom of the upper seat plate is provided with a convex ring matched with the middle seat plate; a sealing ring is arranged between the upper seat plate and the middle seat plate; the upper seat plate is provided with an oil injection hole; and a shock absorbing buffer plate is arranged between the upper seat plate and the middle seat plate. The stepless heightening shock absorbing spherical support provided by the utility model can adjust the height, has no influence on the integral structure of the support, and organically combines the performance advantages of a spherical support and a basin-type support so that a bridge is more durable.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of stepless damping spherical bearing of heightening.
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.Bridge pad comprises spherical bearing and pot bearing.Presently used spherical bearing comprises upper base plate, middle seat board, ball-type steel liner plate and following seat board, is provided with the sphere friction pair between middle seat board and ball-type steel liner plate, is provided with the planar friction pair between ball-type steel liner plate and following seat board.When spherical bearing was installed, bearing level height phenomenon not up to standard appearred in reason such as creep owing to construction error, concrete are inhomogeneous easily.For height of support is mediated, the patent No. is " 200820076682.4 ", patent name can carry out the highly spherical bearing of adjusting for the utility model patent of " ball-type height-adjustable supports " provides a kind of, be provided with the hydraulic pressure hole in the bottom of bearing, after spherical bearing installs, be fed in the hydraulic pressure hole with special tool and heighten injecting, can carry out the stepless adjustment of height of support.This ball-type height-adjustable supports together promotes upper bracket plate, ball-type steel liner plate, middle steel liner plate when heightening, and the structure of whole bearing is caused change, and the use of bearing is caused certain influence.
The utility model content
The technical problems to be solved in the utility model just provides a kind of stepless damping spherical bearing of heightening that again the bearing overall structure is not had influence that can carry out highly regulating.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise upper base plate, middle seat board, ball-type steel liner plate and following seat board, be provided with the sphere friction pair between middle seat board and ball-type steel liner plate, be provided with the planar friction pair between ball-type steel liner plate and following seat board, the bottom of described upper base plate is provided with the bulge loop that is complementary with middle seat board, be provided with sealing ring between upper base plate and middle seat board, have oil filler point on the upper base plate.
Its additional technical feature is: be provided with the damping, buffering plate between described upper base plate and middle seat board; The outside of described sphere friction pair and plane friction pair is respectively arranged with dust ring.
The stepless damping spherical bearing of heightening provided by the utility model is compared with existing ball-type height-adjustable supports, and the bottom of upper base plate is provided with the bulge loop that is complementary with middle seat board, is provided with sealing ring between upper base plate and middle seat board, has oil filler point on the upper base plate.When stepless heighten the damping spherical bearing and install after, if highly not up to standard, in oil filler point, be in a liquid state under the perfusion condition of high temperature, be solid-state polyurethane injecting under the normal temperature, with the stepless jacking of upper base plate, can carry out the stepless adjustment of height of support, finish the purpose of heightening.This heightens process only with the upper base plate jacking, and middle seat board, ball-type steel liner plate and following seat board are not had influence, again the bearing overall structure is not had influence thereby can carry out the height adjusting.And be provided with the damping, buffering plate that rubber or polyurethane are made between upper base plate and middle seat board, and can also play the function of damping, buffering, make bridge superstructure more safe and reliable.This stepless damping spherical bearing of heightening had both kept the feature performance benefit of spherical bearing by the improvement to upper base plate, had absorbed the feature performance benefit of pot bearing again, and the two advantage is organically combined, and made bridge more durable in use.The outside of sphere friction pair and plane friction pair is respectively arranged with dust ring, and sphere friction pair and plane friction pair are played a protective role.
Description of drawings
Accompanying drawing is the stepless structural representation of heightening the damping spherical bearing of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing stepless structure and the principle of heightening the damping spherical bearing provided by the utility model is described in further details.
As shown in the figure, the stepless damping spherical bearing of heightening provided by the utility model comprises upper base plate 1, middle seat board 2, ball-type steel liner plate 3 and following seat board 4, middle seat board 2 and 3 of ball-type steel liner plates are provided with sphere friction pair 5, ball-type steel liner plate 3 and 4 of following seat boards are provided with planar friction pair 6, have oil filler point 7 on the upper base plate 1, the bottom of upper base plate 1 is provided with the bulge loop 8 that is complementary with middle seat board 2,2 of upper base plate 1 and middle seat boards are provided with sealing ring 9 and damping, buffering plate 10, and the outside of sphere friction pair 5 and plane friction pair 6 is respectively arranged with dust ring 11,12.
When using, when stepless heighten the damping spherical bearing and install after, if highly not up to standard, in oil filler point 7, be in a liquid state under the perfusion condition of high temperature, be solid-state polyurethane injecting under the normal temperature, upper base plate 1 stepless jacking, can carry out the stepless adjustment of height of support, finish the purpose of heightening.This heightens process only with upper base plate 1 jacking, and middle seat board 2, ball-type steel liner plate 3 and following seat board 4 are not had influence, again the bearing overall structure is not had influence thereby can carry out the height adjusting.And 2 of upper base plate 1 and middle seat boards are provided with the damping, buffering plate 10 that rubber or polyurethane are made, and can also play the function of damping, buffering, make bridge superstructure more safe and reliable.The outside of sphere friction pair 5 and plane friction pair 6 is respectively arranged with dust ring 11,12, and sphere friction pair and plane friction pair are played a protective role.
The stepless structure of heightening the damping spherical bearing of the utility model is not limited only to above-mentioned form, no matter be to adopt which kind of form, so long as by tank filler sleeve the adjustment of upper base plate is reached the structure that height of support is adjusted, all falls into the utility model protection domain.This is heightened structure and is equally applicable to pot bearing.
