Abstract
The invention discloses a spacing regulation device of a prefabrication box girder, which comprises an internal mold. A walking girder is installed in the internal mold; the internal mold is distributed symmetrically along a centre line; the internal mold further comprises a back form, a side form hinged with the back mold, a corner form hinged with the side form, and a bearing pillar for supporting the back form. The bearing pillar is connected with the walking girder through a hydraulic cylinder; the back form is connected with the side form through the hydraulic cylinder, and the side form is connected with the corner form through the hydraulic cylinder; a spacing regulation mechanism is arranged between the bearing pillar and the walking girder; a bearing stop pin hole is arranged on the bearing pillar; and a stop pin is arranged in and matched with the bearing stop pin hole. Since a wedge-shaped block is adopted, the vertical pressure between the bearing pillar and the walking girder is transformed into the wedge-shaped plane pressure, thus releasing the stress. In addition, double end studs are used for micro-adjusting the entire height and allowing the bearing stop pin to be drawn conveniently.
Description
Technical field
The present invention relates to the site operation apparatus field, especially a kind of means for adjusting limit of movement that is used for the prefabricated case beam of high-speed railway Line for Passenger Transportation.
Background technology
On the high-speed railway Line for Passenger Transportation, in view of the high standard requirement of high speed traveling to the smooth-going performance of circuit, therefore most of highway section all adopts the bridge structure form to cross over, and this makes whole hole hollow prestress box-girder obtain widely applying.In prefabricated process, one of essential heavy construction equipment is exactly the supporting mould one " internal mold " that forms space in the casing.Internal mold mainly comprises backform, with the hinged side form of backform, and a plurality of load-bearing pillars that are used to support backform, this load-bearing pillar is connected with walking beam by hydraulic jack, because may there be error in each parts, needs to carry out the height fine setting between load-bearing pillar and the walking beam, usually way is to regulate by methods such as jack, but install, use all inconveniences, brought very big restriction.Adopt methods such as a thousand pieces of gold top to bring the consequence of discontinuity in addition, and then can influence whole internal mold.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of high speed to carry the prefabricated fine strain of millet case of special line for passenger trains means for adjusting limit of movement.
The technical solution adopted for the present invention to solve the technical problems is: a kind of means for adjusting limit of movement of prefabricated case beam; comprise internal mold; walking beam is installed in the internal mold; described internal mold is symmetrically distributed along center line; described internal mold also comprises backform; with the hinged side form of backform; with the hinged angle mould of side form; and the load-bearing pillar that is used to support backform; this load-bearing pillar is connected with walking beam by hydraulic jack, is connected by hydraulic jack between backform and the side form, is connected by hydraulic jack between side form and the angle mould; be provided with limit adjusting mechanism between load-bearing pillar and the walking beam, the load-bearing pillar is provided with load-bearing backing pin hole.The load-bearing backing pin is equipped with backing pin in the hole.
Further, described limit adjusting mechanism comprises the wedge that is symmetrically distributed along center line, and wedge comprises wedge and following wedge, and following wedge is fixedlyed connected with walking beam, last wedge is positioned at the downside of described backing pin, and described going up adopts studs to connect between the wedge.
Further, described wedge down has " U " type groove, and last wedge has " U " type projection, and described projection can move in described groove.
Further, described limit adjusting mechanism also comprises limiting plate.
Further, the means for adjusting limit of movement of described prefabricated case beam is used for high speed passenger dedicated railway 32m or 24m precast box beam hydraulic automatic narrowing or widening internal mold.
The invention has the beneficial effects as follows owing to adopt wedge, make load-bearing pillar and walking beam between pressure at right angle change cleat planes pressure into, make stressed the alleviation.And that uses that studs finely tunes overall height dimension and withdrawing load-bearing backing pin becomes very convenient.

The specific embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
The means for adjusting limit of movement that is used for high speed passenger dedicated railway 32m or 24m prefabricated case beam as Figure 1-3, comprise internal mold 1, walking beam 3 is installed in the internal mold 1, internal mold 1 is symmetrically distributed along center line 5, internal mold 1 also comprises backform 7, with backform 7 hinged side forms 9, with side form 9 hinged angle moulds 10, and the load-bearing pillar 11 that is used to support backform 7, this load-bearing pillar 11 is connected with walking beam 3 by hydraulic jack, be connected by hydraulic jack between backform 7 and the side form 9, be connected by hydraulic jack between side form 9 and the angle mould 10, be provided with limit adjusting mechanism between load-bearing pillar 11 and the walking beam 3, load-bearing pillar 11 is provided with load-bearing backing pin hole 13, is equipped with backing pin 15 in the load-bearing backing pin hole 13.Regulate overall height dimension by limit adjusting mechanism.Wherein, limit adjusting mechanism comprises the wedge that is symmetrically distributed along center line 5, and wedge comprises wedge 17 and following wedge 19, and following wedge 19 is fixedlyed connected with walking beam 3, last wedge 17 is positioned at the downside of backing pin 15, adopts studs 21 to connect between the last wedge 17.Following wedge 19 has " U " type groove 23, and last wedge 17 has " U " type projection 25, and projection 25 can move in groove 23.Excessively regulate for the screw thread that prevents studs 21 and to break away from wedge 17, limiting plate 27 is arranged in the arranged outside of load-bearing pillar 11.
As shown in Figure 2, when using prefabricated fine strain of millet case internal mold 1, hydraulic jack ejected backform 7 put in place, after side form 9 launches, at first backing pin 15 is inserted load-bearing backing pin hole 13, regulate studs 21, the projection 25 of wedge 17 is moved in the groove 23 of following wedge 19, make that going up wedge 17 is risen, thereby jacking backing pin 15, and then make load-bearing pillar 11 be able to jacking, promptly internal mold 1 is highly regulated and is finished.Keep this state, just can carry out the reinforced concrete box beam and make.
As shown in Figure 3, at last, finish when case is beam prefabricated, after concrete strength reaches demoulding strength, promptly dismountable internal mold, at first regulate studs 21, wedge 17 is descended, and last wedge 17 then takes out backing pin 15 away from backing pin 15, shrink angle mould 10, side form 9, backform 7 by hydraulic jack at last, promptly finish concrete box girder and make.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
