The leg replacing mechanism for the pier side bracket of the bridge pier comprises overhead traveling cranes, electric hoists, a moving trolley, a guide beam and the pier side bracket, wherein two electric hoists are correspondingly arranged on each overhead traveling crane, the guide beam is arranged at the lower bottom surface of support legs of the overhead traveling cranes, the moving trolley is positioned on a chute of the pier side bracket, a leg replacing tripod is also arranged at the outer side of the guide beam and is connected with the moving trolley, the front end part and the back end of the pier side bracket are respectively provided with a front bracket hanging tool beam and a back bracket hanging tool beam, and the two electric hoists drive the front bracket hanging tool beam and the back bracket hanging tool beam through steel strands. The leg replacing mechanism for the pier side bracket of the bridge pier provided by the utility model has the advantages that the construction efficiency of the moving mold frame bridge manufacture can be improved, and the construction period is shortened.
Description
Technical field
The utility model belongs to bridge construction equipment, is specifically related to a kind of bridge pier pier-side bracket and falls leg mechanism.
Background technology
It is a necessary procedure in the use of section assembling bridge formation machine that the bridge pier pier-side bracket falls leg, and present section assembling bridge formation machine both domestic and external generally is to adopt the laddering mode of falling the leg, promptly is leg forward progressively.This mode of falling leg length consuming time, efficient are low, workload can't be saved the duration greatly.
The utility model content
It is a kind of not only simple in structure, reliable that the utility model provides, and not only improved operating efficiency greatly, reduces workload and save the duration, and the bridge pier pier-side bracket that reduces construction cost falls leg mechanism.
In order to reach above-mentioned purpose of design, the technical solution adopted in the utility model is as follows:
A kind of bridge pier pier-side bracket falls leg mechanism, comprise overhead traveling crane, electric block, mobile trolley used, nose girder, pier-side bracket, its overhead traveling crane has two at least, and the platform number of electric block is corresponding with overhead traveling crane, the supporting leg bottom surface that nose girder is arranged at is on the mobile trolley used slideway that is positioned at pier-side bracket; The nose girder outside also is provided with the frame of falling the crural triangle, described frame of falling the crural triangle and mobile trolley used joining; The leading section of pier-side bracket and rear end are respectively arranged with front rack suspender beam and tail-bracket suspender beam, and aforementioned electric block drives front rack suspender beam and tail-bracket suspender beam by steel strand.
Further, the bottom of the described frame of falling the crural triangle is provided with holder, and mobile trolley used end face is provided with sliding seat, and the holder of the described frame of falling the crural triangle and mobile trolley used sliding seat are joined by essence bundle screw thread aluminium.
More specifically, the described frame of falling the crural triangle holder be that the sliding seat of mobile trolley used end face is corresponding with holder to be provided with 4 on 4 four pin that are arranged at the frame of falling crural triangle bottom surface respectively.
Bridge pier pier-side bracket described in the utility model falls the beneficial effect of leg mechanism and is: realized that by the setting of the frame of falling the crural triangle and the frame of falling the crural triangle and the interlock of pier-side bracket bridge pier pier-side bracket great-leap-forward when constructing falls leg, not only improved operating efficiency greatly, reduce workload, and shortened the duration, reduced construction cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is an A part enlarged diagram shown in Figure 1
The specific embodiment
Below in conjunction with Figure of description the specific embodiment of the present utility model is done detailed description.Obviously, described embodiment only is a part of embodiment of the present utility model, and other embodiment that those skilled in the art is obtained under the prerequisite of not paying creative work belongs to protection domain of the present utility model.
As Fig. 1, shown in Figure 2, the utility model comprises overhead traveling crane 1, electric block 2, electric block 3, nose girder 4, mobile trolley used 5, pier-side bracket 6, wherein correspondence is provided with two electric blocks 2 on the crossbeam 11 of overhead traveling crane 1,3, mobile trolley used 5 are positioned on the pier-side bracket 6, supporting leg 12 lower positions of overhead traveling crane 1 match with nose girder, nose girder 4 arranged outside have the frame of falling the crural triangle 7, the bottom of the frame of falling the crural triangle 7 is provided with holder 71 in the present embodiment, mobile trolley used 5 end faces are provided with sliding seat 51, and the holder 71 of the frame of falling the crural triangle 7 is connected by the smart screw thread aluminium of pricking with mobile trolley used 5 sliding seat 51; The leading section of pier-side bracket 6 and rear end are respectively arranged with front rack suspender beam 61 and tail-bracket suspender beam 62, and the electric block 2 on the aforementioned runway girder 11, electric block 3 drive front rack suspender beam 61 and tail-bracket suspender beam 62 by steel strand respectively.
As required, the holder of the frame of falling the crural triangle can be provided with 4, be set in respectively on four pin of the frame of falling crural triangle bottom surface, the sliding seat of mobile trolley used end face is 4 and corresponding setting with holder too, makes fixing more firm between mobile trolley used and the frame of falling the crural triangle like this.
Concrete construction sequence is as follows:
The nose girder both sides are provided with this structure pier-side bracket mechanism respectively, two pier-side brackets run through the finish rolling deformed bar location, realize when falling the leg mechanism, the chassis on the and arranged on left and right sides pier-side bracket is traversing go out a segment distance after, with another finish rolling deformed bar chassis and the frame of falling the crural triangle are connected and fixed.Preposition electric block drives front rack suspender beam by twisted wire, electric block hoists, making left and right pier-side bracket form certain angle tilts, remove this moment under the acting in conjunction of chassis sideslip oil cylinder and preposition electric block, to make outside the pier-side bracket again behind the finish rolling deformed bar of pier-side bracket and move, connect overhead traveling crane inboard electric block and carriage tail-bracket suspender beam with steel strand this moment, removes finish rolling deformed bar fixing between tail-bracket suspender beam and chassis and the frame of falling the crural triangle.Traversingly again go out pier-side bracket, the electric block that hoists is had bad luck to leading pier, thereby the great-leap-forward of realizing pier-side bracket falls leg.
It should be noted that at last: above embodiment only is used to illustrate the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
