Description
Technical field
The present invention relates to Highway bridge technique fields, and in particular to a kind of telescopic device of highway bridge.
Background technique
With the fast development of economic construction of China, using highway to go out as the high-grade highway of representative is emerged rapidly in large numbersBamboo shoots after a spring rain
Existing, traffic volume of highway sharply increases, and the travel speed of driving vehicle and the axis of vehicle focus on growth on highway, and people relax to driving
The problem of requirement of adaptive etc. is higher and higher, therefore in previous Bridge Design, construction, payes attention to inadequate related telescopic device becomes
It is more and more prominent, force Bridge Design, construction, maintenance and administrative department adequately to pay attention to this.The flexible dress of highway bridge
It sets, is mostly installed at the expansion joint between two parts of bridge beam body, wheel load is directly born in bridge structure
Repeated stock effect, and is chronically exposed in atmosphere, and use environment is more severe, be bridge structure be most subject to destroy and
Relatively it is difficult to the position repaired.
Existing Expansion Units for Highway Bridges, is largely modulus type Expansion Units for Highway Bridges, and structure is two abnormal shapes
Steel and rubber strip, rubber strip are located between two profile irons.The telescopic device has the following problems: 1, the rubber strip of the device is sudden and violent
It is exposed at the external world, the immersion with rainwater is rolled by vehicle, accelerates the degree of aging of rubber strip.2, due to rubber strip difference portion
The deflection of position is different, and rubber strip is caused to be easy to block, and is not easy to replacement rubber strip.
Summary of the invention
The invention is intended to provide a kind of telescopic device of highway bridge, rubber strip is protected, and convenient for rubber strip
Replacement.
In order to achieve the above objectives, the present invention adopts the following technical scheme: a kind of telescopic device of highway bridge, including it is flexible
Mechanism and two vertically arranged fixed plates, telescoping mechanism are located between two fixed plates, and the outside of fixed plate is spaced setting
There are multiple sheet metals, sheet metal tilts upward setting；Telescoping mechanism includes multiple rubber strips and multiple vertical bars, rubber strip and solid
Fixed board is mutually perpendicular to, spaced and parallel setting between multiple rubber strips, and multiple rubber strips are connected by vertical bar, each rubber strip
Both ends are rotatably connected to idler wheel, and the side of idler wheel and fixed plate is slidably connected, and the upper end of two fixed plates, which is hinged with, prolongs
Stretch plate, overlapped between extension board and be slidably connected, the equal level in the lower end of two fixed plates is fixedly connected with support plate, and two
Gap is equipped between support plate；Vertical bar is divided into multiple struts, is mutually detachably connected between multiple struts.
The utility model has the advantages that
1, rubber strip is placed between two fixed plates, two are prolonged in the present invention by setting fixed plate and extension board
It stretches overlapped between plate, plays a protective role to rubber strip, rubber strip is avoided directly to be rolled the leaching with rainwater by vehicle
Bubble, extends the service life of rubber strip.Meanwhile being slidably connected between two extension boards, gap is equipped between two support plates,
Extendable room is provided for rubber strip, will not influence the Telescopic of rubber strip.
2, sheet metal is set in the outside of fixed plate in the present invention, pulley is arranged in the both ends of rubber strip, not due to rubber strip
It is different with the deflection at position, it can be by catching vertical bar to pull out rubber strip, setting pulley reduces rubber strip and consolidates
Friction between fixed board.Meanwhile sheet metal is to tilt upward setting, and when telescoping mechanism is not all detached from fixed plate, fixed plate
It can smoothly move downward, but cannot outward pull out, avoid taking fixed plate out of when replacement rubber strip, can guarantee in this way
When replacing rubber strip, the telescopicing performance of whole highway bridge will not influence.
3, rubber strip is divided into the present invention multiple, and is attached using vertical bar, vertical bar is divided into multiple removable
The strut for unloading connection causes rubber strip that can only pull out a part, can will connect since the deflection of rubber strip different parts is different
There is the strut of rubber strip to disassemble to be replaced, rubber strip is avoided to block, and it is more convenient to replace rubber strip.
Further, the upper end between two neighboring vertical bar is connected by elastic strip, holds elastic strip for rubber convenient for people
Adhesive tape pulls out, more convenient operation.
Further, the first convex block is provided in support plate, the lower end of vertical bar offers first with the cooperation of the first convex block
Groove, convenient for positioning to vertical bar, so that the rubber strip between vertical bar carries out dilatation, the deformation of rubber strip is more steady
It is fixed.
Further, the quantity of vertical bar be two, the distance between two vertical bars be greater than vertical bar with side wheel it
Between distance, increase the deformation space between rubber strip, and guiding and support played the role of by vertical bar, so that rubber
The dilatation of band is more stable.
Further, the end of extension board is equipped with sealing block, and sealing block is vertically arranged, and the rainwater in outside or dust is avoided to enter
Gap between two extension boards avoids the two from blocking so that being slidably connected between two extension boards is more smooth.
