Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As Figure 1-3, be the fuel transfer device tiltable frame that the utility model provides, this tiltable frame comprises that Open Side Down U-shaped framework 4, framework 4 adopts welded structure, and its dimensions according to the size design of rickle fuel assembly, thus ensures accurate positioning.The front portion of this framework 4 is provided with balanced connection mechanism 1 for being connected with lifting mechanism, for supporting head mechanism 2 and the balance plate axle 3 of fuel transfer device carrier, balanced connection mechanism 1, head mechanism 2, balance plate axle 3 are bolted with framework 4.The tail end of framework 4 is provided with rear cover disc 5, rear cover disc 5 is connected with framework 4 by bolt, the bearing 7,9 preventing fuel transfer device carrier loader from putting in place is respectively equipped with in the both sides of rear cover disc 5, two bearings are connected with the track 19 of fuel transfer device by bolt, adopt this connected mode, simple to operate, be convenient to maintenance.Each bearing is provided with semicircle axis hole, and this axis hole coordinates with the rotating shaft of fuel transfer device carrier afterbody, as the fulcrum of tiltable frame, overturn with fuel assembly, when travelling bogie puts in place, the rotating shaft of fuel transfer device carrier afterbody enters axis hole, dolly stop motion.
Each bearing is provided with two adjustment support plates 8,10 for adjusting tiltable frame position.During installation, the position of tiltable frame can regulate support plate 8,10 to ensure by adjustment.
The afterbody of tiltable frame is provided with ballast box 6, and this ballast box 6 is connected with rear cover disc 5, when ensureing that tiltable frame is in vertical position, can be turned to horizontal level voluntarily.
Balanced connection mechanism 1 comprises spring 11, fork-shaped bearing 12, balance plate 13 and rotating shaft 14.Fork-shaped bearing 12 is connected by balance plate axle 3 with head construction 2, and balance plate 13 is arranged on fork-shaped bearing 12, and rotating shaft 14 is located on balance plate 13, and spring 11 is arranged on outside fork-shaped bearing 12, is the overturning buffering ensureing tiltable frame.Balance plate 13 is connected with the wire rope of two on hoisting gear respectively, is undertaken vertically, flip horizontal by rope traction tiltable frame.When this balanced connection mechanism 1 can ensure that fracture occurs steel cable, another steel cable completes operation of tumbling.
