Abstract
The utility model relates to a twin movable die carrier outer formwork folding device comprising two hang beams, rotary hang beams, bottom dies, outer formworks, rotary outer formworks and outer formwork supporting rods I. The rotary hang beams are rotationally mounted on hang beams through rotary shafts V, the bottom dies are mounted on the rotary hang beams through spiral ejectors respectively, the outer formworks are mounted on the bottom dies respectively, the tail ends of the rotary outer formworks are rotationally mounted on the outer formworks through rotary shafts IV respectively, and two ends of the outer formwork supporting rods I are fixedly hinged to the rotary hang beams and the outer formworks respectively. After a concrete beam is cast, the hang beams drive the outer formworks to strip downwardly, then a movable connecting block is detached from the two rotary hang beams, an outer formwork rotating device drives the rotary outer formworks to rotate and get close to the outer formworks through the rotary shafts IV, since the movable connecting block are detached, the outer ends of the rotary outer formworks are placed in the clearance between the two rotary hang beams, and finally a hang beam rotating device drives the rotary hang beams to rotate till below the hang beams with the outer formworks through the rotary shafts V. The device is still adaptive when the clearance between the twin box girders is eliminated or small.

Detailed description of the invention
Below in conjunction with accompanying drawing 1, accompanying drawing 2, the utility model is described further.
This double width mobile formwork exterior sheathing folding device, comprise two drop in beams 1, rotate by rotating shaft V 19 the rotation drop in beam 2 being installed on each drop in beam 1 respectively, be installed on the bed die 17 on each rotation drop in beam 2 by spiral top 18, be installed on the exterior sheathing 10 on each bed die 17, tail end rotates the rotation exterior sheathing 12 and the two ends hinged external mold strut I 13 of rotating on drop in beam 2 and exterior sheathing 10 that is fixed on respectively that are installed on each exterior sheathing 10 by rotating shaft IV 15, between two rotation drop in beams 2, be provided with gap, some movable contact blocks alive 3 are positioned at Zhong Qieqi two ends, gap and are secured by bolts in respectively on two rotation drop in beams 2, also comprise for driving rotation drop in beam 2 to turn to the drop in beam tumbler of drop in beam 1 below and rotate for driving the exterior sheathing tumbler that exterior sheathing 12 rotates to exterior sheathing 10 directions by rotating shaft IV 15 by rotating shaft V 19, rotating exterior sheathing 12 its outer end movement locus in the time rotating does not interfere with each other with the position of rotating drop in beam 2.The drop in beam 1 that when original state, drop in beam tumbler drives two rotation drop in beams 2 relatively to install is separately positioned at same straight line, and the driving of exterior sheathing tumbler is rotated exterior sheathing 12 and launched, and now can carry out the work of building of concrete beam 16.After concrete beam 16 has been built, drop in beam 1 drives the downward stamping die of exterior sheathing 10, afterwards work movable contact block 3 being rotated to drop in beam 2 from two disassembles, exterior sheathing tumbler drives rotation exterior sheathing 12 to be rotated and draw close to exterior sheathing 10 by rotating shaft IV 15, due to the movable contact block dismounting of living, the outer end of therefore rotating exterior sheathing 12 can be placed in two gaps of rotating between drop in beam 2.Final drop in beam tumbler drives rotation drop in beam 2 to turn to drop in beam 1 below by rotating shaft V 19.And rotate drop in beam 2 while rotating, pull exterior sheathing 10 to turn to the below of drop in beam 1 by external mold strut I 13, therefore realize the demoulding and deciliter via hole of exterior sheathing 10, due to lower swing, so hour still can be suitable for for very close to each other between two width case beams or gap.
Drop in beam tumbler can be for following structure it comprise that the hinged oil cylinder I 4 that is fixed on drop in beam 1 below of tail end, top rotate by rotating shaft II 8 the connecting rod I 5 and the top that are installed on drop in beam 1 and rotated and be installed on the connecting rod II 6 of rotating on drop in beam 2 by rotating shaft III 9, the piston rod head end of connecting rod I 5, connecting rod II 6 and oil cylinder I 4 is rotationally connected by rotating shaft I 7 mutually.The piston rod of oil cylinder I backhauls moving mutually, can pull connecting rod I 5 and connecting rod II 6 to rotate around rotating shaft II 8 and rotating shaft III 9, and connecting rod II 6 pulls rotation drop in beam 2 to rotate around drop in beam 1 by rotating shaft V 19 simultaneously, until the drop in beam 1 of its rotation under, and optimum state is parallel with drop in beam 1 for turning to.Drop in beam tumbler is simple in structure, reliable.Exterior sheathing tumbler can for following structure, it comprises oil cylinder II 11, and oil cylinder II 11 tail ends are hinged to be fixed on exterior sheathing 10, and hinged being fixed on of its piston rod head end rotated on drop in beam 2.The piston rod of oil cylinder II 11 is moved back to realize and pulls rotation exterior sheathing 12 to turn folding withdrawal by the relative exterior sheathing 10 of rotating shaft IV 15, thereby has guaranteed the demoulding and deciliter via hole of exterior sheathing 10, simple in structure, reliable.
Can also comprise external mold strut II 14, external mold strut II 14 one end are installed on rotates on drop in beam 2, and its other end is installed on and rotates on exterior sheathing 12.External mold strut II 14 can improve in the time that concrete beam 16 is built, and rotates the support stiffness of exterior sheathing 12, avoids the excessive situation about damaging that causes of oil cylinder II 11 load-carryings to occur.After concrete beam 16 is built, external mold strut II 14 is dismantled, easy-to-use.
