Abstract
The utility model discloses a cable-stayed movable suspended scaffolding provided with a long platform and free from cable force adjustment. The movable suspended scaffolding comprises the loading platform, wherein a stretching system is arranged at the front end of the loading platform and includes an anchor head connector, a cable staying pull rod, an anchor beam and a piercing lifting jack; the anchor head connector is connected with a stayed cable; one end of the cable staying pull rod is connected with the anchor head connector, the other end of the cable staying pull rod penetrates a stretching groove of a loading platform main longitudinal beam, the anchor beam and the lifting jack, and the tail end of the cable staying pull rod is fixed through a pull rod nut. The utility model is free from the cable force adjustment from the pouring construction, thereby reducing the construction control difficulty.
Description
Technical field
The utility model relates to a kind of construction equipment that concrete deck cable stayed bridge kingpost cantalever pouring construction is used, and especially a kind ofly exempts to transfer the rope long platform tiltedly to draw Hanging Basket.
Background technology
In the cantilever pouring work progress of cable stayed bridge concrete girder, linear control is primary often.In construction control process in the past, in order to improve construction equipment (Hanging Basket) global stiffness and to reduce distortion, usually need English truss be set or must during the process of building, repeatedly adjust Suo Li at bridge floor, so just increase the control difficulty of work progress, be unfavorable for linear control on the contrary.
The utility model content
The utility model purpose be to provide a kind of in the process of building, do not need to adjust Suo Li exempt from transfer the rope long platform tiltedly to draw Hanging Basket.
For achieving the above object, the technical solution adopted in the utility model is: a kind ofly exempt to transfer the rope long platform tiltedly to draw Hanging Basket to comprise plummer, front end at plummer is provided with tensioning system, this tensioning system is made up of anchor head connector, guy rope pull bar, anchor beam, punching jack, the anchor head connector is connected with suspension cable, guy rope pull bar one end is connected with the anchor head connector, and the other end passes stretch-draw groove, anchor beam and the jack of plummer main longitudinal grider successively, and end is fixed by pull-rod nut.
The rear end of described plummer main longitudinal grider is provided with the suspension cable thrust brake.
After the utility model adopts said structure, by front end tensioning system is set at plummer, this tensioning system is made up of anchor head connector, guy rope pull bar, anchor beam, punching jack, the anchor head connector is connected with suspension cable, guy rope pull bar one end is connected with the anchor head connector, the other end passes stretch-draw groove, anchor beam and the jack of plummer main longitudinal grider successively, and end is fixed by pull-rod nut; Because anchor beam is the front fulcrum of Hanging Basket, can slide up and down and lock along the circular arc bearing surface, thereby the position of front fulcrum is adjustable, to adapt to the variation of suspension cable angle.During the system conversion, pretensioning guy rope pull bar loosens pull-rod nut, jack slowly loosens then, the drag-line nut is stressed to be compressed, and the anchor head connector is removed in the system conversion at last, Hanging Basket separates with suspension cable, so by tensioning system of the present utility model is suspension cable and Hanging Basket to be coupled together when the Hanging Basket cantilever casting construction formation front fulcrum, applies certain tensile stress to suspension cable, with the internal force that reduces main longitudinal grider in the construction with reduce front end and be out of shape; After cantilever is finished, suspension cable is separated with Hanging Basket, realize the Suo Li conversion, avoided in the pouring construction process, adjusting Suo Li.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model longitudinal plane structure schematic diagram;
Fig. 2 is the utility model tensioning system structural representation.
Among the figure: 1 plummer, 11 through holes, 12 annular lip, 2 tensioning systems, 21 anchor head connectors, 22 guy rope pull bars, 23 anchor beams, 24 jack, 25 pull-rod nuts, 3 suspension cables, 4 suspension cable thrust brakes.
The specific embodiment
Shown in Fig. 1 and 2, of the present utility modelly exempt to transfer the rope long platform tiltedly to draw Hanging Basket to comprise plummer 1, front end at plummer 1 is provided with tensioning system 2, this tensioning system 2 is made up of anchor head connector 21, guy rope pull bar 22, anchor beam 23, punching jack 24, anchor head connector 21 is connected with suspension cable 3, guy rope pull bar 22 1 ends are connected with anchor head connector 21, and the other end passes stretch-draw groove, anchor beam 23 and the jack 24 of plummer main longitudinal grider 11 successively, and are terminal fixing by pull-rod nut 25; Rear end at plummer main longitudinal grider 11 also is provided with suspension cable thrust brake 4.The tensioning system 2 of plummer 1 front end is suspension cable 3 and Hanging Basket to be coupled together the formation front fulcrum when the Hanging Basket cantilever casting construction, applies certain tensile stress for suspension cable 3, with the internal force that reduces main longitudinal grider 11 in the construction with reduce the front end distortion; After cantilever is finished, suspension cable 3 is separated with Hanging Basket, realize the Suo Li conversion, avoided in the pouring construction process, adjusting Suo Li; Anchor beam 23 is front fulcrums of Hanging Basket, can slide up and down and lock along the circular arc bearing surface, thereby the position of front fulcrum is adjustable, to adapt to the variation of suspension cable 3 angles.During the system conversion, pretensioning guy rope pull bar 22 loosens pull-rod nut 25, and jack 24 slowly loosens then, drag-line nut 25 stressed compressing, and anchor head connector 21 is removed in the system conversion at last, and Hanging Basket separates with suspension cable 3.
