Abstract
The utility model relates to the technical field of jacking devices, in particular to a bridge jacking device which comprises a fixing plate. The fixing plate is fixedly installed on the lower surface of a bridge. A plurality of hydraulic jacks are uniformly arranged on the fixing plate and connected with pipeline connecting openings which are connected with pipelines. The pipelines connected to the pipeline connecting openings are controlled by the same PLC synchronous jacking control mechanism. According to the bridge jacking device, the hydraulic jacks are of a set of integrated structures synchronously fixed to the fixing plate on the lower surface of the bridge and are controlled by the same PLC synchronous jacking control mechanism, and therefore each hydraulic jack can apply force on a bridge uniformly.
Description
Technical field
The utility model relates to the technical field of lift-up device, especially a kind of bridge jacking device.
Background technology
In bridge board jack-up construction; usually can use hydraulic jack; and these hydraulic jack are generally the individuality of independent distribution; control centre need to control respectively it; increase the volume of whole control device, also increased the workload of maintenance system, simultaneously because each hydraulic jack is separately bridge soffit to be carried out to the application of force respectively; so each hydraulic jack is inhomogeneous to the power of bridge soffit, easily cause bridge force-bearing inequality and run-off the straight phenomenon.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the problem of the prior art existence in above-mentioned background technology, a kind of improved bridge jacking device is provided, by being that one group of monolithic construction is synchronously fixed on the fixed head on bridge soffit by multiple hydraulic jack, and by the control of same PLC synchronization of jacking up controlling organization, ensure the uniform force application of each hydraulic jack to bridge.
The utility model solves the technical scheme that its technical problem adopts: a kind of bridge jacking device, comprise the fixed head being fixedly installed on bridge soffit, on fixed head, be evenly provided with multiple hydraulic jack, in multiple hydraulic jack, be all connected with pipeline connection, on pipeline connection, be connected with pipeline, the pipeline connecting on each pipeline connection is by the control of same PLC synchronization of jacking up controlling organization.
Further limit: what be evenly arranged at multiple hydraulic jack on fixed head takes over a business to be sped structure.
Further limit: the quantity that is evenly arranged at the hydraulic jack on fixed head is 3.
The beneficial effects of the utility model are, bridge jacking device of the present utility model, by being that one group of monolithic construction is synchronously fixed on the fixed head on bridge soffit by multiple hydraulic jack, and by the control of same PLC synchronization of jacking up controlling organization, improve the control efficiency of control system, ensure the uniform force application of each hydraulic jack to bridge, bridge soffit has been played to good jacking effect.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of hydraulic jack.
In figure: 1, fixed head, 2, hydraulic jack, 2-1, take over a business 3, pipeline connection, 4, pipeline, 5, PLC synchronization of jacking up controlling organization.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Fig. 1 and Fig. 2 bridge jacking device, comprise the fixed head 1 being fixedly installed on bridge soffit, on fixed head 1, be evenly provided with multiple hydraulic jack 2, in multiple hydraulic jack 2, be all connected with pipeline connection 3, on pipeline connection 3, be connected with pipeline 4, the pipeline 4 connecting on each pipeline connection 3 is controlled by same PLC synchronization of jacking up controlling organization 5.
The 2-1 that takes over a business that is wherein evenly arranged at the multiple hydraulic jack 2 on fixed head 1 is sped structure.The quantity that is evenly arranged at the hydraulic jack 2 on fixed head 1 is 3.
This bridge jacking device, by being that one group of monolithic construction is synchronously fixed on the fixed head 1 on bridge soffit by multiple hydraulic jack 2, and controlled by same PLC synchronization of jacking up controlling organization 5, improve the control efficiency of control system, ensure the uniform force application of each hydraulic jack 2 to bridge, bridge soffit has been played to good jacking effect.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to claim scope.
