Description
Technical field
Bridge maintaining equipment is the utility model is related to, particularly a kind of bridge abutment correcting device.
Background technology
As overhead road of city, grade separation bridge are increasing, the height of many viaduct viaducts reaches more than ten meters or even more
It is high, it is necessary to there is higher pier stud to match, and the pier stud of overhead road of city grade separation due to traffic above-ground to be considered, greening, pipeline and
The factors such as beauty, therefore be typically designed smaller of pier section and be much Single column pier, although this kind of bridge pier shape is lightly beautiful
See, but ought highly reach more than certain value (15m), since pier stud lateral stiffness is relatively small, used, in construction abnormal
Inconsiderate, bridge pier ambient conditions change considered there are hidden danger of quality, design etc. may cause pier stud top displacement deviation excessive, shadow
Ring the normal use of structure, it is therefore desirable to rectify a deviation to it, and also there is no deviation correcting device at present.
Utility model content
The purpose of this utility model is that, there is provided a kind of bridge abutment correcting device.It has spy simple in structure, stability is good
Point.
The technical solution of the utility model：A kind of bridge abutment correcting device, including deviation-rectifying bracket, deviation-rectifying bracket is interior to be equipped with silk
Thick stick, the both ends of leading screw are respectively equipped with plus thread and left-hand thread, and plus thread is connected with correction nut, and left-hand thread connects with location nut
Connect；Correction base is connected with the correction nut；Deck is connected with the location nut；Under the deviation-rectifying bracket
Side is additionally provided with roller；Guide rail is also respectively connected in the correction base and deck；The leading screw is also associated with driving device.
In foregoing bridge abutment correcting device, the cushion block that can be replaced is additionally provided with the correction base.
Compared with prior art, the utility model sets leading screw in deviation-rectifying bracket, and the both ends of leading screw are respectively equipped with positive spiral shell
Line and left-hand thread, are attached, correction nut and location nut are also with correction nut and location nut respectively by positive and negative screw thread
Connection correction base and deck respectively；By the structure, when rectifying a deviation to bridge pier, deck is stuck in connecing for two bridge main bodies
Between seam, driving device, which starts, drives leading screw, and driving correction base and deck move inward under the cooperation of positive and negative screw thread, use
Correction base rectifies a deviation bridge pier the thrust of bridge pier, and due to the use of mechanical transmission, stability is good during its work, and passes through
Driving device drives the structure of leading screw, substitutes hydraulic-driven, eliminates hydraulic system, simplify device structure.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the usage state diagram of the utility model.
Mark in attached drawing for：1- deviation-rectifying brackets, 2- leading screws, 3- plus threads, 4- left-hand threads, 5- correction nuts, 6- positioning
Nut, 7- correction bases, 8- decks, 9- rollers, 10- guide rails, 11- cushion blocks, 12- bridge piers, 13- bridge main bodies.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment 1.A kind of bridge abutment correcting device, is formed as shown in Figs. 1-2, including deviation-rectifying bracket 1, is set in deviation-rectifying bracket 1
Have a leading screw 2, the both ends of leading screw 2 are respectively equipped with plus thread 3 and left-hand thread 4, and plus thread 3 is connected with correction nut 5, left-hand thread 4 with
Location nut 6 connects；Correction base 7 is connected with the correction nut 5；Deck 8 is connected with the location nut 6；
The lower section of deviation-rectifying bracket 1 is additionally provided with roller 9；Guide rail 10 is also respectively connected in the correction base 7 and deck 8；It is described
Leading screw 2 be also associated with driving device.
The cushion block 11 that can be replaced is additionally provided with foregoing correction base 7., can be local by setting replaceable cushion block 11
The component of abrasion is replaced, in the case of ensureing device stable operation, reduces maintenance cost.
In use, deck 8 is stuck between the seam of two bridge main bodies 13, driving device (not embodied in figure), which starts, drives silk
Thick stick 2, driving correction base 7 and deck 8 move inward under the cooperation of positive and negative screw thread, right using the cushion block 11 on correction base 7
The thrust of bridge pier 12 rectifies a deviation bridge pier 12；During correction, relative displacement, deviation-rectifying bracket 1 can occur between deviation correcting device and bridge pier
The roller 9 of lower section can effectively reduce the frictional resistance between deviation correcting device and bridge pier, mitigate the load of driving device, extend and use
Service life.
