Description
Technical field
The present invention relates to bridge field, be specially a kind of covering mechanism for bridge expanssion joint.
Background technology
The road surface of bridge is often provided with expansion joint, in order to provide the allowance expanded with heat and contract with cold.For traffic safety and the serviceability safeguarding bridge pavement, generally require and this expansion joint is carried out elastomeric objects filling or covering.Known mode is to adopt the materials such as gum elastic to carry out covering or clogging.But, the installation of this elastic rubber material needs the matrix of road pavement to carry out the reprocessing such as surface cutting, in order to install described elastomeric material in place.And this easily causes and produces these working positions when driving to damage and then damage road surface matrix.And the installation and removal for this elastomeric material are also required to expend a large amount of manpower and time cost.
Summary of the invention
It is an object of the invention to provide a kind of covering mechanism for bridge expanssion joint, it can overcome defect of the prior art.
nullThe covering mechanism for bridge expanssion joint according to the present invention，For the road surface place of bridge expanssion joint is covered，Including the rubber body flushed with the level height of bridge pavement、It is positioned at the supporter within described rubber body、And can towards and away from mobile and that structure is symmetrical two extension support members in described supporter，Wherein，Said two extend in support member each include can level is slided in the chute of described supporter horizontal extension head、The vertical extension connected with described horizontal extension head and the support arm connecting with the lower end of described vertical extension and extending towards adjacent bridge structure body，Wherein，Said two extends the end of support member and is provided with the support plate in order to abut with described adjacent bridge structure body，The end face of described support plate is provided with the shear pin being inserted in the shearing hole being arranged on described adjacent bridge structure body；Wherein, the vertical extension of two extended in support member is fixedly installed disengagable lock hook, another vertical extension is fixedly installed the disengagable locking dop of correspondence, being provided with the action bars that cross section is ellipse between described disengagable lock hook and described disengagable locking dop, described action bars is rotatably supported in be fixed on the supporting bar being connected with described bridge structure body；Wherein, the gib head protuberance of described disengagable lock hook includes being connected with adjacent bridge structure body and downward-sloping upper flexible extension and described upper flexible extension are connected vertical extension and the lower end that is positioned at described vertical extension；Described disengagable locking dop includes connected with adjacent bridge structure body and acclivitous lower flexible extension, is positioned at the card head of described lower flexible extension end, when described disengagable lock hook is in mutual lock-out state with described disengagable locking dop, described gib head protuberance engages thus realizing linking locking with the adjacent surface of described card head, now, the oval major axis of the cross section of described action bars is horizontal direction；nullWhen the major axis that described action bars rotates the ellipse to cross section is vertical direction，The adjacent surface of described gib head protuberance and described card head departs from thus realizing unlocking，Now，Said two extends support member and a described support plate can be made under the effect of the top pressure spring being located at therebetween to be pressed on adjacent bridge structure body and make in the shearing hole that described shear pin is inserted into correspondence，The vertical extension extended in support member on described right side is provided with groove and drive motor，It is provided with movable block in described groove，Described movable block coordinates fixing connection with described top pressure spring，Described movable block bosom position is provided with screw shell，Described movable block is embedded in described groove，And sliding connection，Described slot opening place is provided with the first spacing block set，The described movable block edge of described inside grooves is provided with the second spacing block set，Described first spacing block set and described second spacing block set are connected，Described drive motor is provided with screw rod，Described screw rod runs through the vertical extension on described right side and is connected with described screw shell threaded engagement，Described shear pin outer surface is surrounded with tight buffer spring，Described tight buffer spring is fixing with described support plate near described support plate one end to be connected，Described tight buffer spring plays cushioning effect in order to extend when support member connects with the shearing hole of bridge structure body in said two，And also there is fastening locking functions.
Pass through the present invention, can elastic back down and two support arm parts away from each other owing to being provided with, by coordinating with the supported hole on the side of matrix and can by place for the elastomeric material supporting at road surface place and flush with road surface by end card and the friction of matrix side.And this device is easily installed, reason is in that, it is before the mounting by being arranged on the sealed of hook part between two support arms and card head member, enable to two support arms and be in contraction state close to each other, therefore it is easy in the gap being successfully inserted between matrix, when described cladding system is fixed in place by needs, it is operated by the elliptic cross-section action bars with major axis shape, enable to described hook part and card head member disengages, thus the end of two support arms is pushed up press to matrix side to realize fixing by the elastic top opening force of elastic top pressure part.More importantly, when the described action bars with elliptic cross-section is in the contraction state vertical with described disengaged condition, by extruding or push said two support arm opposite to each other, said two support arm can close to each other and make described hook part and dop component elasticity deformation and be changed into locked state from disengaged condition thus described cladding system is converted to contraction state.This can carry out the conversion operation of this contraction state when transporting described cladding system manufacturing complete, it is also possible to takes when cladding system is removed by needs from flexible gap.This is have the arranging of respective guiding surface being engaged with each other time close to each other and realize by having the setting of the flexible rod portion tilted toward each other from respective arm and hook part and card head member automatically into the performance of locked state by pushing.And by arranging described action bars when being in described plumbness, it allows described hook part to move enough amounts to allow chain conjunction of described hook to disengage towards this action bars, and pushing said two support arm and be close to each other so that described action bars can servo-actuated or slave mode be followed freely rotatable to avoid interference with described sealed action when entering locked state.Whole apparatus structure is simple, runs ingenious, it is possible to operate easily to realize installation and removal effect, thus saving time and the cost of labor of installation and removal, and uses reliable, stabilized structure.
