Description
Technical field
The present invention relates to road and bridge field, more particularly to a kind of road and bridge bearing.
Background technology
With the continuous quickening of urban construction, highway construction is also constantly being accelerated, and the place in river is passed through in highway construction
Need to use bridge, road and bridge bearing is used for the upper part and lower part for connecting bridge, and existing road and bridge bearing uses spring mostly
Enter row buffering, spring can be reduced using rear cushioning effect for a long time, influence the cushion effect of road and bridge bearing, and spring exposure for a long time
It can corrode on outdoor boundary.
The content of the invention
It is an object of the invention to provide a kind of road and bridge bearing, to solve above-mentioned technical problem.
The present invention uses following technical scheme to achieve the above object：
A kind of road and bridge bearing, including upper plate, lower plate, buffer, rubber column, the lower plate are provided with the buffer that screw is installed
And rubber column, buffer and rubber column top are provided with upper plate, and the bottom of the upper plate is provided with the first groove and the second groove,
Buffer is arranged in the first groove, and rubber column is arranged in the second groove, and the rubber column is hollow design, and rubber is stood
It is provided with post in second spring, first groove and is welded with the first spring, the free end of the first spring is welded with projection, is delayed
The top for rushing device offers neck close to the position of upper plate, and projection matches with neck, and through hole is in same horizontal line with neck
On, permanent magnet is placed in through hole.
It is preferred that, the buffer includes connecting cylinder, cylinder body, piston rod, and connecting cylinder is arranged on lower plate, cylinder body by screw
In connecting cylinder, fill resisting medium in cylinder body, the bottom of cylinder body offers fluid hole, piston rod by sealing piston with
Cylinder body is connected.
It is preferred that, it is described raised for metal material, buffer surface smear anti-corrosion material.
It is preferred that, the second spring uses pagoda spring.
Compared with prior art, the present invention has advantages below：The present invention is simple in construction, reasonable in design；When have vehicle or
When vibrations are by road and bridge, piston rod is moved down under the effect of the pressure, and piston rod is by the resisting medium in cylinder body through fluid hole
It is pressed into connecting cylinder, so as to the pressure of top is transferred in resisting medium, after distress resolves, on the piston rod in cylinder body
Move, by the resisting medium suction cylinder body in connecting cylinder；Most of shaking force is laid down by buffer, the design drop of buffer
Influence of the low path bridge to the first spring；Buffer can solve the influence expanded with heat and contract with cold to road and bridge simultaneously；Rubber outside second spring
Glue column avoids second spring for a long time exposed to extraneous situation about corroding, and second spring can provide bridge secondary slow
Impulse force；Neck prevents buffer from coming off with male cooperation, ensures raised tight with neck in the presence of permanent magnet and the first spring
Contiguity is touched, and is preferably promoted the use of.

Embodiment
The present invention is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As Figure 1-5, a kind of road and bridge bearing, including upper plate 1, lower plate 5, buffer 6, rubber column 3, the lower plate 5
The buffer 6 and rubber column 3 installed provided with screw, buffer 6 and the top of rubber column 3 are provided with upper plate 1, the upper plate 1
Bottom be provided with the first groove 13 and the second groove 14, buffer 6 be arranged on the first groove 13 in, buffer 6 include connecting cylinder
10th, cylinder body 9, piston rod 8, connecting cylinder 10 are arranged on lower plate 5 by screw, and cylinder body 9 is arranged in connecting cylinder 10, filled in cylinder body 9
Resisting medium is filled, resisting medium can offer fluid hole 11 using the oily liquids such as gear oil, the bottom of cylinder body 9, and piston rod 8 leads to
Cross sealing piston to be connected with cylinder body 9, back-moving spring is installed in cylinder body（It is to mark in figure）, it is recessed that rubber column 3 is arranged on second
In groove 14, the rubber column 3 is to be provided with second spring 12, first groove 13 to weld in hollow design, rubber column 3
The first spring 16 is connected to, the free end of the first spring 16 is welded with projection 15, and the top of buffer 6 is opened close to the position of upper plate 1
Provided with neck 2, projection 15 matches with neck 2, and projection is metal material, buffer surface smear anti-corrosion material, through hole 4 and card
Groove 2 is in same horizontal line, and permanent magnet 7 is placed in through hole 4.
Operation principle of the present invention：By road and bridge bearing by bolt be arranged on bridge pier on, the pressure above bridge it is excessive or
When having vibrations, the piston rod 7 of buffer 6 can be moved down, the resisting medium in cylinder body 9 is by going out liquid in cylinder body 9 under force
Hole 11 is discharged into connecting cylinder 10, so that the power on bridge be laid down, after pressure is removed, resisting medium enters cylinder by fluid hole 11
