Specific implementation mode
A kind of modular big corner damping shock absorption Multidirectional displacement bridge expansion device, for the two neighboring beam body of bridge 1
Between expansion joint 2 be adjusted, the expansion joint 2 along bridge cross-bridges direction be arranged, the telescopic device include borrow respectively
Help anchoring assembly 3 to be installed in adjacent beam body 1 and cross one another fishback, it is important to, the fishback include one end with
The fixed plate 4 of the connection of anchoring assembly 3, the beaming roller 5 that 4 lower section of fixed plate is set to along cross-bridges direction and one group of split type activity
The other end of broach 6, the fixed plate 4 is arranged at intervals with double wedge 7 and recessed portion 17, and the beaming roller 5 is connected with double wedge 7,
The root 8 of the movable broach 6 is set to recessed portion 17 and is hinged by connection component and beaming roller 5, is set in the beam body 1
The support unit being equipped in expansion joint 2, the support unit are used to support the end of movable broach 6 in adjacent beam body 1
9。
Embodiment 1, as shown in Figs. 1-5, beaming roller 5 are welded and fixed with the double wedge 7 in fixed plate 4, the connection component packet
Link block 13, bolt 15 with beaming roller hole 14 are included, link block 13 is arranged below movable broach 6, and the upper table of link block 13
Face is bonded with the lower surface of movable broach 6, and the beaming roller hole 14 on link block 13 is set on beaming roller 5 to be coordinated with beaming roller 5, bolt 15
Link block 13 and movable broach 6 are connected, i.e., movable broach 6 is mounted on beaming roller 5, movable broach 5 has along the axis of beaming roller 5
There are the degree of freedom of rotation, bottom bracket axle 5 to be provided in the abutting end of adjacent two beam body 1, no matter beam body 1 upwarps or sink equal energy
It is close to be both provided with elasticity for the rotation of realization activity broach 6 between movable broach 6 and fixed plate 4, between link block 13 and beam body 1
Packing 16, drives link block 13 to generate rotation when movable broach 6 rotates, movable broach 6, link block 13 squeeze elastic sealing gasket
16, it prevents fixed plate 4 or beam body 1 from generating interference to movable broach 6 or link block 13 and hinders its rotation.And elastic sealing gasket 16
It is arranged and to keep good sealing performance between fixed plate 4 and movable broach 6, has both ensure that the normal rotation of movable broach 6,
Gap is not generated again, prevents sundries from falling between fixed plate 4 and movable broach 6 or falling into beam body 1 to beam body 1, telescopic device
It damages.Wherein bolt 15 is dormant bolt, contributes to link block 13 to be contacted with elastic sealing gasket 16 well, reduces rotation
It hinders.
Support unit includes the support plate 10 being connected with right side beam body 1, the high-damping supporting block being set in support plate 10
11, high-damping supporting block 11 is located at 9 lower section of end of the movable broach 6 in adjacent two beam body 1, and high-damping supporting block 11 is to activity
The end 9 of broach 6 plays a supportive role, and when bridge stretches, movable broach 6 is slided in the upper surface of high-damping supporting block 11
It is dynamic.The upper end of high-damping supporting block 11 is camber end 12, reduces the friction between movable broach 6, makes the sliding of movable broach 6
It is lighter.Meanwhile when beam body upwarps or sinks, the rotation of movable broach 6 not by the obstruction of high-damping supporting block 11,
And always by the resilient support of high-damping supporting block 11, rigid support will not be generated to movable broach 6, prevent movable broach 6 by
Crushing is bad.The vibration for the generations such as the also absorbable vehicle of high-damping supporting block 11 travels, bridge is flexible, the production of effective noise reduction function
It is raw.The high-damping supporting block 11 is the supporting block for the lamination shape that steel plate 18 and rubber are made up of heat cure, with General Purpose Rubber branch
Seat is reduced the distortion allowance of bearing, i.e., is supported with the smaller high-damping of thickness compared to bigger, more reliable vertical bearing capacity
The supporting role to movable broach 6, the reliability of guarantee activity broach 6 can be realized in block 11.
Fixed plate 4 is to realize to be connected by built-in fitting and beam body 1, the movable broach 6 on right side, high-damping supporting block 11,
Support plate 10 and fixed plate 4 form the imitated structure of closed parallelogram, and overall performance is good.When movable broach 6 turns downwards
When dynamic, fixed plate 4 remains stationary as, and flexible deformation occurs for high-damping supporting block 11, and micro Bending Deformation occurs for support plate 10, high
The rebound after external force disappearance of 11 energy accumulation of Damper Braces block makes movable broach 6 reset, and is truly realized the rotation of movable broach 6
Function.
Embodiment 2 is the another embodiment of high-damping supporting block 11, as shown in fig. 6, high-damping branch in the present embodiment
Bracer 11 includes two groups of steel plates 18 in left and right settings, the interspersed setting of two groups of left and right, about 18 steel plates, in two groups of steel of overlook direction
The abutting end of plate 18 is overlapped, which compared with Example 1, has preferably soft when initial stressed squeezes
Property, elastic bigger can absorb more vibrational energies, when high-damping supporting block 11 is during compressed, two groups of left and right
The vertical distance of 18 adjacent end portion of steel plate is gradually reduced, i.e. the elasticity in 11 centre position of high-damping supporting block becomes smaller, rigidity reinforced,
The reliability of intermediate supports is improved, and both sides still have good elasticity, and supporting point and rotation amount are provided for movable broach 6,
Realization activity broach 6 preferably rotates.
Fixed plate 4 and beam body 1 are connected by the present invention, and the beaming roller 5 using on movable broach 6 and fixed plate 4 is hinged, movable comb
The rotation of tooth 6 is not interfered with beam body 1, can really realize that rotation keeps smooth posture when beam body 1 upwarps or sinks,
Avoid the damage of entire telescopic device.
