Abstract
The utility model relates to a bridge maintaining device, particularly to a bridge climbing system, which comprises a climbing device and a climbing support, wherein the climbing support is arranged below the bridge to be lifted, and the climbing device is arranged between the climbing support and the bridge to be lifted. The utility model has the advantages of simple structure, convenient use and extensive application.
Description
Technical field
The utility model relates to a kind of bridge inspection and maintenance device.
Background technology
The replacing of bridge pad must be striden bridge superstructure integral elevating one or several striding, and need not interrupt or as far as possible shorten the time that suspends traffic.Traditional equipment is two classes, and a class is to rely on the manually-operated jack, with one stride or and stride in unified lifting of beam, the unified action of one people's number of crying out, shortcoming is to need manpower many, unified operation easier is big, performance accuracy is limited, generally can only be used for less bridge.Second class is the improvement on first kind basis: with hydraulic circuit each oil cylinder is together in parallel, reaches the purpose of synchronous lifting by the operating terminal hydraulic valve.This method personnel selection is few, and synchronism is than the first kind, but the oil cylinder number of each control valve control is limited, and a plurality of fulcrum jackings need be used a plurality of control valves, and the simultaneously operating between each valve is difficult to control.
Summary of the invention
The objective of the invention is to avoid the deficiencies in the prior art that bridge jacking system a kind of simple in structure, easy to operate is provided.
For achieving the above object, the technical scheme that the present invention takes is: a kind of bridge jacking system, include lift-up device, and also include the jacking pillar, the jacking pillar is arranged on by jacking bridge below, is provided with lift-up device at the jacking pillar and between by the jacking bridge.
Further, described jacking pillar includes at least one jacking pillar, and described jacking pillar is made up of at least one tubular steel post.
Further, described jacking pillar is provided with two at least, and described jacking pillar is made up of at least two tubular steel posts, connects by flange between the tubular steel post.
Further, described at least two jacking pillars are mutually permanently connected by flat link rod.
Further, described flat link rod is connected with tubular steel post by the otic placode that described tubular steel post is provided with.
Further, be connected by anchor ear or bar planting between described jacking pillar and bridge pier column and the abutment.
Further, described lift-up device includes at least one oil cylinder, and described oil cylinder is arranged on jacking pillar top.
Further, be provided with pressure sensor on described lift-up device, pressure sensor is connected with computer radio or is electrically connected.
Further, also include lifting appliance, described lifting appliance includes and the suitable scaffold of described jacking pillar height, and lifter is established in the scaffold lower end, and lifter is connected by rope with the driven rotation Kun that the scaffold upper end is provided with.
Further, described lifter includes hollow lift shaft, and the lift shaft two ends are provided with the hollow cylinder projection, is provided with spacer pin on hollow cylinder, also is provided with the unidirectional locking wheel on the lift shaft of at least one hollow cylinder projection one side; In hollow lift shaft, be provided with the lifting joystick; On the end face at hollow lift shaft two ends, be provided with at least one handle socket and at least one lifting rope fixing hole.
The beneficial effects of the utility model are: all points that need to promote, land all must be synchronously; Lifting, landing process are steadily carried out, and the height that can be maintained fixed for a long time, do not need to suspend traffic just can operate.Because tubular steel post, the application of the special-purpose lifting appliance of anti-slip oil cylinder have enlarged the range of application of this cover Lifting Equipment.Except that simply supported girder bridge, at continuous bridge, pedestrian overcrossing can be changed operations such as bearing, structure correction, elevation adjustment, emergency repair.It is practical, can be according to clear height independent assortment under the beam, and easy to operate, do not need large-scale hanging device.Operating efficiency, safe coefficient, construction precision all are that traditional handicraft can't be compared.Guaranteed all lift points synchronization liftings, lifting process is steady, controlled, and the duration is controlled.The needs of satisfy the bearing maintenance fully, changing.
