The working condition of border bridge is adaptively moved, and adapts to the big movement under mal-condition, and structure is simple, easy to implement.
To achieve the above object, The technical solution adopted by the invention is as follows:
A kind of novel bridge expansion joint adaptive mechanism, including being in interval at least two bridge surface armor plates arranged side by side
It is arranged at least two groups mobile mechanism；Each described mobile mechanism connect with bridge surface armor plate described in each and is used to make
Between the bridge surface armor plate can automatic adaptation level direction is mobile or vertical direction is mobile or horizontal direction and vertical direction simultaneously
It is mobile.
Further, the mobile mechanism includes sliding rail, is in the multiple sliding blocks being arranged in a one-to-one correspondence with the bridge surface armor plate
Component；The slide block assembly includes the slider bracket connected with the corresponding bridge surface armor plate, be can be rotated with the slider bracket
The sliding block of connection, the sliding block slidable connection of the sliding rail and each slide block assembly.
Further, the sliding rail is provided with the boss for preventing the sliding block from skidding off at both ends.
Further, the slider bracket includes the vertical support arm connecting with the bridge surface armor plate, and described vertical
The transverse arm of the upper end connection of support arm, the transverse arm are rotatably connected with the sliding block.
Further, positioned at outside two mobile mechanisms two slide block assemblies positioned at outside institute
Vertical support arm is stated to be two and be symmetrical set in the two sides of the sliding rail.
Further, the both ends of the bridge surface armor plate are located at positioned at two mobile mechanisms in outside.
Further, the bridge steel plate is three, and the mobile mechanism is three groups and is equally arranged.
Compared with prior art, the invention has the following advantages:
The bridge surface armor plate of two sides of the present invention and the end of bridge are attached, when the end of bridge relatively moves,
Drive the bridge surface armor plate at the mechanism both ends mobile, thus realize that horizontal direction is mobile, vertical direction is mobile and horizontal direction and
Vertical direction is mobile simultaneously, adapts to the big movement under mal-condition；The present invention is not necessarily to external connection power unit, and bridge floor can be realized
The movement of steel plate, structure is simple, and easily controllable, and stability is good.
Detailed description of the invention

Fig. 2 is schematic diagram when the embodiment of the present invention adaptation level is mobile.
Fig. 3 is schematic diagram when the embodiment of the present invention adapts to vertical shift.
Schematic diagram when Fig. 4 is mobile the embodiment of the present invention adaptation level simultaneously and vertical shift.
Wherein, the corresponding title of appended drawing reference are as follows:
1- bridge surface armor plate, 2- mobile mechanism, 21- sliding rail, 22- slide block assembly, 221- slider bracket, 222- sliding block.
Specific embodiment
To keep the purposes, technical schemes and advantages of the application apparent, with reference to the accompanying drawings and examples to the present invention
It is described further, embodiments of the present invention include but is not limited to the following example.
Embodiment
As shown in Figures 1 to 4, a kind of novel bridge expansion joint adaptive mechanism is present embodiments provided, needs to illustrate
It is that the serial numbers term such as " first ", " second ", " third " in the present embodiment is only used for distinguishing same item, cannot be understood as pair
The specific restriction of protection scope.In addition, the positional terms such as " bottom ", " top ", " side edge " in the present embodiment are based on attached
Figure illustrates.
The novel bridge expansion joint adaptive mechanism, including being set in interval at least two bridge surface armor plates 1 arranged side by side
It sets at least two groups mobile mechanism 2；Each mobile mechanism 2 connect with each bridge surface armor plate 1 and for making bridge surface armor plate
It can automatic adaptation level direction movement or vertical direction movement or horizontal direction and vertical direction movement simultaneously between 1.
Wherein, mobile mechanism 2 includes sliding rail 21, is in the multiple slide block assemblies 22 being arranged in a one-to-one correspondence with bridge surface armor plate 1；It is sliding
Block assembly 22 includes the sliding block being rotatably connected with slider bracket 221 with the slider bracket 221 of corresponding bridge surface armor plate 1 connection
222,222 slidable connection of sliding block of sliding rail 21 and each slide block assembly 22, the pivot center and bridge surface armor plate 1 of sliding block 222
Vertically.
To avoid sliding rail 21 from skidding off sliding block 222,21 both ends of sliding rail are provided with boss.
Specifically, slider bracket 221 includes the vertical support arm connecting with bridge surface armor plate 1, upper with vertical support arm
The transverse arm of connection is held, transverse arm is rotatably connected with sliding block 222.
For guarantee stability, positioned at the Liang Ge mobile mechanism 2 in outside two slide block assemblies 22 positioned at outside it is vertical
Support arm is two and is symmetrical set in the two sides of sliding rail 21 that two support arms are connect with transverse arm.
For the synchronism for guaranteeing 1 both ends of bridge surface armor plate, the Liang Ge mobile mechanism 2 positioned at outside is located at bridge surface armor plate 1
Both ends.
This example Bridge steel plate 1 is three, and mobile mechanism 2 is three groups and is equally arranged.Of course, bridge steel
Length, width, thickness, quantity and the quantity of mobile mechanism 2 of plate 1 can be all adjusted according to Practical Project demand.
The present invention is in use, the bridge surface armor plate of the mechanism two sides and the end of bridge are attached, specific connection type root
Be divided into following two according to bridge material: (1) when bridge is steel box girder bridge, bridge surface armor plate and bridge top plate are welded by connecting plate
It connects, while guaranteeing that bridge surface armor plate is concordant with bridge floor；(2) when bridge is beams of concrete, beam-ends reinforcing bar and bridge surface armor plate pass through company
Fishplate bar welding, while guaranteeing that bridge surface armor plate is concordant with bridge floor.The lower surface of bridge surface armor plate is arranged in mobile mechanism when connection, not shadow
Vehicle normal pass is rung, when relative displacement occurs for the end of bridge, drives the bridge surface armor plate at both ends mobile, to realize level
Direction movement, vertical direction movement and horizontal direction and vertical direction are mobile simultaneously.The present invention is not necessarily to external connection power unit, i.e.,
The movement of bridge surface armor plate can be achieved, structure is simple, and easily controllable, and stability is good, has very high popularization and application foreground.
Above-described embodiment is only one of the preferred embodiment of the present invention, should not be taken to limit protection model of the invention
It encloses, as long as that in body design thought of the invention and mentally makes has no the change of essential meaning or polishing, is solved
The technical issues of it is still consistent with the present invention, should all be included within protection scope of the present invention.
