Description
Technical field
The present invention relates to a kind of traffic highway bridge fishback telescopic device technical field, specifically a kind of highway bridge comb
Tooth plate telescopic device.
Background technique
Expansion Units for Highway Bridges is one of the important component of highway bridge construction, and function is to make bridge structure object
Under the action of the factors such as temperature change and the contraction of concrete or steel, creeping displacement and dynamic load, it is able to maintain freely more
The flexible of direction is tieed up, to adapt to the various modifications of highway bridge structure, being must can not in guarantees a highway bridge normal operation
Few structural devices.
With increasing sharply for the volume of traffic and heavy goods vehicles, especially overloading is serious in recent years, keeps highway bridge flexible
The destruction situation of device is increasingly severe, and the telescopic device of highway bridge is exposed in the atmosphere of field for a long time in, uses ring
Border is more severe, is most to be subject to destroy in bridge structure and be relatively difficult to the position repaired.
Expansion Units for Highway Bridges is generally various types comb teeth retractor device in the prior art, passes through docking fishback
Block interts to realize its retractility mutually, but each adjacent fingers vertical side is plane, and causing each comb teeth is cantilever
The comb teeth front end state of beam, the deformation of comb teeth independent stressed limit constraint support without upper and lower vertical direction from each other, can not
Transmitting displacement load force mutually, is easy fatigue fracture, leads to serious traffic safety accident；In addition in installation and in use, comb teeth
It is readily formed hanging stress, under the vehicle-mounted pressure effect of long-term dynamics, comb teeth may be deformed and be upwarped, therefore serious shadow
Ring traffic safety.
Therefore I authorized before application (Authorization Notice No.: CN208455468U, authorized announcement date:
2019.02.01 a kind of highway bridge fishback telescopic device disclosed in), by fixed broach and across the neighboring vertical for stitching comb teeth
Lateral layout is corresponding groove and convex block, can not only have been guaranteed across the free to slide of seam comb teeth horizontal direction, but also can transmit change
Position load force increases comb teeth intensity and globality, and driving is improved service life by flatness, simultaneously because foring up and down
The flexible constraint of limit supports, and will not deform and upwarp across seam comb teeth, therefore ensure that traffic safety.
But above-mentioned apparatus occurs following disadvantage in actual use process: 1, since the convex block across seam comb teeth is located at admittedly
In the groove for determining comb teeth vertical side lower end, between convex block and groove the contact of full tooth long side surface be face contact, frictional resistance compared with
Greatly, therefore the sluggish or stuck of the torsional deflection across seam comb teeth horizontal direction is resulted in, causes comb teeth to damage, reduces using the longevity
Life.
2, since the convex block across seam comb teeth is located in the groove of fixed broach vertical side lower end, convex block must be combed from fixed
In the end insertion groove of tooth, and it is longer across seam comb teeth and fixed broach, therefore it requires the place of biggish construction；Separately
Outside, in installation or maintenance, complete extraction or insertion also improve difficulty of construction, influence site operation efficiency.
Summary of the invention
Technical problem to be solved by the present invention lies in: because the face contact of tooth long side surface complete between convex block and groove causes
Comb teeth damage, to reduce service life；Existing device requires the place of larger construction, and installs and construct when repairing
Difficulty is big, and construction efficiency is low.
In order to solve the above technical problems, the invention provides the following technical scheme:
A kind of highway bridge fishback telescopic device, including fixed broach plate, across seam fishback, connect with fixed broach plate
Multiple fixed broach and with across seam fishback connect it is multiple across seam comb teeth, the fixed broach with across stitch comb teeth be it is staggeredly embedding
Insert arrangement, which is characterized in that the fixed broach and/or across seam comb teeth a side or two sides on be arranged it is fluted,
The groove extends along fixed broach or across seam comb teeth direction of extension, the comb teeth front end across seam comb teeth and/or fixed broach
It is provided with the convex block with matching grooves, the groove and convex block, which constitute one, can make fixed broach restrict hang down across seam comb teeth
Sliding equipment of the histogram to displacement；The groove is provided with up and down at fishback close to fixed broach plate and/or across stitching
Installation passage, form and dimension and the convex block of the installation passage match.
As a further solution of the present invention: described across, embedded with across seam length steel plate, guarantee is combed across seam in seam fishback
The structural strength of tooth plate.
As further scheme of the invention: auxiliary lug is provided in the middle part of the fixed broach, it is described across seam comb teeth
Middle part is correspondingly arranged on and the matched groove of auxiliary lug and installation passage.
As further scheme of the invention: described that seam comb teeth middle part is provided with auxiliary lug, the fixed broach
Middle part is correspondingly arranged on and the matched groove of auxiliary lug and installation passage.
As further scheme of the invention: the auxiliary lug is one, and cooperation convex block uses, so that across seam comb teeth
When sliding more than the different positions stress point so that uniform force, simultaneously because its with convex block be with into moving back, because
This will not influence the difficulty of construction of installation or maintenance.
As further scheme of the invention: the auxiliary lug has multiple and is in arranged for interval, so that stress is more
Uniformly.
As further scheme of the invention: described to be integrally formed across seam fishback with across seam comb teeth.
As further scheme of the invention: the fixed broach plate is identical as across seam fishback structure, same mold
It is made, reduces production cost, while there is preferable intercommunity, facilitate the installation at scene.
As the present invention further scheme: the fixed broach plate and across end face is neat thereon after seam fishback assembly
It is flat-shaped.
As the present invention further scheme: described across seam fishback is polypropylene modification butylbenzene with carbon fiber modifying
Rubber, the thermoplastic polyurethane elastomer rubber of carbon fiber modifying, ultra-high molecular weight polyethylene, high density polyethylene (HDPE), polyamide,
One of acrylic resin, acetal resin or the composition of a variety of any combination are material.
Compared with prior art, the beneficial effects of the present invention are: 1, by the bump design of comb teeth front end, by original full tooth
The face contact of long side surface is changed to point contact, it is easier to carry out adaptive multi-directional deflection, improve device overall flexibility, avoid sliding
Dynamic sluggish or stuck caused comb teeth damage, to improve service life.
2, due to the design of installation passage, convex block is enabled directly to reach groove by installation passage, then pull compared with
Fixed broach restrict can be realized after small distance across seam comb teeth vertical direction displacement, avoid plug-type mounting means
The problem that caused construction site is big, difficulty of construction is big and construction efficiency is low.
3, auxiliary lug cooperates convex block to use, so that in different position multiple spot stress when across seam comb teeth sliding, to make
Uniform force is obtained, simultaneously because it is to move back with into same, therefore will not influence the difficulty of construction of installation or maintenance with convex block.
4, when being provided with installation passage on across seam comb teeth, relatively due to the width across seam comb teeth at installation passage
It is narrow, therefore its flexibility is improved in structure, further increase multi-directional deflection function.
