The present invention changes the fault of construction of conventional telescopic device technique, and the comparison prior art has the advantages that
(1) conjugate excellent performance: QE product devises a swing system in movable plate one end, passes through the system any direction
Rotation.When rotating under the effects of beam body is in temperature, vehicle-mounted, wind-force, the rotation system of device can be rotated with bridge and
It rotates.Displacement protective housing is increased in the position of swing system, rotation system and concrete support system is allowed independently to separate,
Keep the two stress independent of one another, is independent of each other.To one group every meter, self-contained module breaks the whole up into parts the whole suitable bridge of device.Level angle
It is evenly distributed in each module with torsional deflection, actively adapts to the displacement of bridge, it is ensured that device runs well.
(2) structural behaviour: the present invention uses modular designs, each component functional independence, clear, be conducive to design, manufacture,
The quality control of the links such as detection, installation, replacement, monitoring.Using being flexibly connected, load impact force is logical for the present apparatus and beam body
It crosses elastic material to absorb and transmit, weakens beam body vibration significantly, deforms the destruction to telescopic device, anti-fatigue performance is obviously excellent
More in other structures.Meanwhile the present invention uses freely supported structure, fishback is whole across beam-ends gap, and structure is reasonable, prolonged
It is durable.The mutually interspersed arrangement of comb teeth, each comb teeth only 6~8cm wide, intersects always when being subjected to displacement and does not depart from.Fishback direction
It is consistent with vehicle pass-through direction, impact force when wheel transition is reduced, driving is smooth, comfort is good.
(3) environmentally friendly damping performance: the present invention increases the buffering of 5mm thickness between big platelet and concrete support structure
Part is provided with high-damping wear-resistant material in displacement shock absorber part, reduces wheel to the impact force of device, not only protects device, but also
Reduce noise.Meanwhile requirement of the product to preformed groove is lower, (15~25cm of buried depth), when sharp pounding occurs, no
It will cause device and cause beam body to damage the impact force of beam body.
(4) from maintainability: transverse joint plate of the invention is integrally covered on beam-ends gap, and rubbish will not fall into breathing zone
Domain.Telescopic device is close to continuously with stainless steel slide plate, will not be invaded by rubbish, and the rubbish between comb teeth is pushed away by force by domatic comb teeth
Out, and by driving it takes away, beam-ends gap will not be entered.Rainwater is automatically imported waterstop by device after the excretion of bridge floor drain hole
Discharge, waterproof performance are preferable.Waterstop uses canvas rubber, non-aging breakage.
(5) repair, conserve it is convenient: when the present invention repair, independent disassembling, assembling and replacing damage module.Pacify with modulus type device
Dress is calculated with valence with the service life, and operation cost is only the 1/5 of modulus type.
