Description
Technical field
The utility model relates to the anchorage style in a kind of movable bridge, relates in particular to a kind of vertical transfer movable bridge pin rack rails anchor structure that is used for.
Background technology
Movable bridge is meant and is navigation needs, the bridge of mode foldings such as superstructure can be revolved perpendicularly to revolve, to put down, lifting.Busy when land transport, ship's navigation is arranged on the river and fixed bridge can not be built in navigational clearance when above, just need to build movable bridge, thereby to solve land and water transportation.Movable bridge commonly used has: the 1. upright bridge that changes.The bridge of the rotatable folding on facade of the bridge span structure above the navigation channel.The whole title list Ye Shili that strides bascule changes bridge from an end folding; Folding is divided into the upright bridge that changes of title double-valve type of two parts bascule from two ends.Bascule is provided with mechanical device and electrical equipments such as hinge and balance weight.2. lift bridge.The spanning of navigation part is made liftable structure, and respectively there is a pylon at the movable bridge two ends, places with mechanical, electrical device and balance weight.3. swing bridge.Bridge span structure is around the movable bridge of a vertical pivot rotation.No matter be the movable bridge which kind of opens form; All can relate to the anchoring of different modes; Require will to be satisfied its peripheral shearing and resistance by the bearing capacity of anchoring body after the anchoring, especially to the anchoring of pin tooth driving member also special demands steel member wherein can carry out the gap adjustment according to the difference of environment temperature.At present, direct pre-buried steel member is adopted in guideway wall and the anchoring between the rack rails in to movable bridge in the transmission of pin tooth usually, because concrete need vibrate; Add the concrete shrinkage reason; The position of steel member is difficult to guarantee, therefore, can not reaches the job requirement of mechanical system.
The utility model content
To above-mentioned prior art, the utility model provides a kind of anchor structure of vertical transfer movable bridge pin rack rails, this anchor structure can make the construction error of the rack rails of pin tooth transmission be controlled at ± 0.5mm within.
In order to solve the problems of the technologies described above; The utility model is that the technical scheme that the anchor structure of vertical transfer movable bridge pin rack rails is achieved is: this anchor structure; Comprise guideway wall and rack rails fixation steel plate; Anchoring between said guideway wall and the rack rails fixation steel plate; Said anchoring is made up of the adjusting screw(rod) pre-embedded steel slab of exempting to shake little swollen concrete connecting portion, a plurality of adjusting screw(rod) and be arranged on each adjustment screw bar, and an end of said adjusting screw(rod) is fixed with the adjusting screw(rod) pre-embedded steel slab that is arranged in the guideway wall, and the other end of said adjustment screw bar and said rack rails fixation steel plate are fixed.
The utility model is the anchor structure of vertical transfer movable bridge pin rack rails, and wherein, a plurality of described adjusting screw(rod)s are circumferentially to be symmetric arrangement along guideway wall.Be provided with a plurality of cutouts or shearing screw with said rack rails fixation steel plate contact jaw on said little swollen concrete connecting portion of exempting to shake.
Compared with prior art the utlity model has following beneficial effect:
Since vertical transfer movable bridge key of success be to the construction error of pin tooth and transmission rack rails be controlled at ± 0.5mm within, if construction error has expansion slightly, will cause equipment attrition, the reduction service life of equipment.Simultaneously, because variations in temperature throughout the year needs the maintenance of stopping transport.The pin rack rails anchor structure that the utility model is used for movable bridge can make the construction precision of rack rails fixation steel plate satisfy the requirement of mechanical system ± 0.5mm, and promptly the radius of circle at rack rails fixation steel plate place changes requirement.In the technology of anchoring, comprise first phase concreting part and the little swollen concrete part of shaking of exempting from of second phase.Wherein, in the first phase concreting, vibrate because of needs adopt machinery, if directly imbed steel member group wherein, construction error only can reach ± 20mm, is 40 times that mechanical system requires.And be to regulate the rack rails fixation steel plate through adjusting screw(rod) in the utility model, can satisfy the mechanical system requirement; In exempting from of building of second phase shaken little swollen concrete, because of little swollen concrete of exempting to shake need not vibrate, and anti-contracility can be superior, the positional precision that makes the rack rails fixation steel plate within ± 0.5mm, thereby effectively control construction error.In addition, cutout in the utility model or shearing screw can satisfy force request.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done to describe in further detail.
As depicted in figs. 1 and 2; The anchor structure of the utility model vertical transfer movable bridge pin rack rails; Comprise guideway wall 1 and rack rails fixation steel plate 2; Anchoring between said guideway wall 1 and the rack rails fixation steel plate 2, said anchoring is made up of the adjusting screw(rod) pre-embedded steel slab 33 of exempting to shake little swollen concrete connecting portion 31, a plurality of adjusting screw(rod) 32 and be arranged on each adjustment screw bar, and a plurality of described adjusting screw(rod)s 32 are circumferentially to be symmetric arrangement along guideway wall 1; One end of said adjusting screw(rod) 32 is fixing with the adjusting screw(rod) pre-embedded steel slab 33 that is arranged in the guideway wall 1, and the other end of said adjustment screw bar 32 and said rack rails fixation steel plate 2 are fixing.Be provided with a plurality of cutouts 4 with said rack rails fixation steel plate 2 contact jaws on said little swollen concrete connecting portion 31 of exempting to shake; Said cutout 4 is used for resisting shearing; Cutout 4 wherein is provided with in order to satisfy force request; Certainly, also can adopt other form of structure to replace, for example: shearing screw etc.
The technology that realizes the utility model is: use ordinary concrete material construction guideway wall 1, the pre-buried adjusting screw(rod) pre-embedded steel slab 33 of elder generation before construction guideway wall 1.Be fixed on rack rails fixation steel plate that assembles in advance 2 and cutout 4 on the adjusting screw(rod) pre-embedded steel slab 33 through adjustment screw bar 32 then.The length of adjustment adjusting screw(rod) 32 realizes through rotating its top nut, and then the position of adjustment rack rails fixation steel plate 2, its position is met the demands after, build again and exempt to shake little swollen concrete.Because of little swollen concrete of exempting to shake need not vibrate, and anti-contracility can be superior, and the positional precision that makes the rack rails fixation steel plate is within ± 0.5mm.
In the utility model mentioned to the little swollen concrete that shakes of exempting from of exempting to shake that little swollen concrete connecting portion adopted belong to the known technology in the present technique field; Be meant: improve concrete flowability and shrinkage through proportioning; Do not need machinery to vibrate when building and just can reach self-compaction, and shrinkage factor is lower.
Although top combination figure is described the utility model, the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, rather than restrictive.
