Description
Technical field
The present invention relates to a kind of bridge auxiliary device more particularly to a kind of bridge aseismic devices.
Background technique
Bridge refers generally to be erected in rivers,lakes and seas, the structures for making traffic etc. that can smoothly pass through.It is modern to adapt to
The transportation industry of high speed development, bridge be also extended to across mountain stream, unfavorable geology or meet other traffic need and set up make
Current more convenient and fast building.Bridge is generally made of superstructure, substructure, support and attached structure, top knot
Structure is also known as bridge span structure, is across the primary structure of obstacle；Substructure includes abutment, bridge pier and basis；Support is spanning knot
The load transfer device of the bearing place setting of structure and bridge pier or abutment；Attached structure then refer to transition slab at bridge head, truncated cone banking, shore protection,
Training works etc..In the prior art, the guardrail of bridge, sunpender or junction are required to connect, if it is solidifying to directly adopt concrete
Gu being then unable to antidetonation, therefore, junction needs the attachment device of shock-absorbing.
Summary of the invention
The object of the invention is that providing a kind of bridge aseismic devices to solve the above-mentioned problems.
The present invention through the following technical solutions to achieve the above objectives:
The present invention includes shell, lid, connecting rod, connecting rod lug boss, connecting rod connection ring, the first movable spring seat, the second work
The inside lower section internal diameter of flexible spring seat, spring, nut and shell connection ring, the shell is less than the interior of the enclosure interior upper section
Diameter, the first movable spring cover for seat is loaded on the connecting rod can be movable, and the first movable spring seat and the connecting rod
Lug boss contact, the second movable spring cover for seat is loaded on the connecting rod can be movable, and it is living that the spring is located at described first
Between flexible spring seat and the second movable spring seat, the nut is connect with the end thread of the connecting rod, and described second
Movable spring seat is contacted with the nut, and the connecting rod connection ring is fixedly installed on the other end of the connecting rod, the connecting rod peace
The part for filling the first movable spring seat and the second movable spring seat is located at the intracorporal upper section of the shell, and described second is living
Flexible spring seat is contacted with the lower section intersection of the shell, there is through-hole in the middle part of the lid, and the upper section of the connecting rod passes through institute
Lid is stated, is threadedly coupled between the lid and the shell, the shell connection ring is fixedly installed on the lower end of the shell.
The beneficial effects of the present invention are:
The present invention is a kind of bridge aseismic devices, and compared with prior art, the present invention has the effect of bidirectional damping, when this
When the outside power in the both ends of invention, connecting rod is pulled, and the second movable spring seat compressed spring plays the role of damping, works as the present invention
Inward at both ends power when, connecting rod is compressed, and the first movable spring seat compressed spring plays cushioning effect, to have two-way subtract
The effect of shake is effectively played the anti seismic efficiency of bridge junction, is had the value of popularization and application.
Detailed description of the invention
Fig. 1 is cross-sectional view of the structure of the invention.
In figure: 1- shell, 2- lid, 3- connecting rod, 4- connecting rod lug boss, 5- connecting rod connection ring, the first movable spring of 6- seat,
The second movable spring of 7- seat, 8- spring, 9- nut, 10- shell connection ring.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
The present invention is living including shell 1, lid 2, connecting rod 3, connecting rod lug boss 4, connecting rod connection ring 5, first as shown in Figure 1:
Flexible spring seat 6, the second movable spring seat 7, spring 8, nut 9 and shell connection ring 10, the inside lower section internal diameter of the shell 1
Less than the internal diameter of the 1 inside upper section of shell, the first movable spring seat 6 is set on the connecting rod 3 can be movable, and institute
It states the first movable spring seat 6 to contact with the connecting rod lug boss 4, the second movable spring seat 7 is set in energy on the connecting rod 3
Enough activities, the spring 8 positioned at the first movable spring seat 6 and the second movable spring seat 7 between, the nut 9 and
The end thread of the connecting rod 3 connects, and the second movable spring seat 7 is contacted with the nut 9, the connecting rod connection ring 5
It is fixedly installed on the other end of the connecting rod 3, the connecting rod 3 installs the first movable spring seat 6 and the second movable bullet
The part of spring abutment 7 is located at the upper section in the shell 1, and the lower section intersection of the second movable spring seat 7 and the shell 1 connects
There is a through-hole at touching, the middle part of the lid 2, and the upper section of the connecting rod 3 passes through the lid 2, the lid 2 and the shell 1 it
Between be threadedly coupled, the shell connection ring 10 is fixedly installed on the lower end of the shell 1.
When the outside power in both ends of the invention, connecting rod 3 is pulled, and 7 compressed spring 8 of the second movable spring seat plays damping
Effect, when the power of inward at both ends of the invention, connecting rod 3 is compressed, and 6 compressed spring 8 of the first movable spring seat plays damping
Effect, to have the effect of bidirectional damping, effectively plays the anti seismic efficiency of bridge junction.
Basic principles and main features and advantages of the present invention of the invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
