A kind of adjustable hanging apparatus of immersed tube tunnel final joint, including some hangers on FS final spice,
Lifting rope of the one ends wound on hanger bearing pin, sleeve gasket has been wrapped on the bearing pin.A kind of immersed tube tunnel final of the utility model connects
The adjustable hanging apparatus of head, in a disguised form the effective of lifting rope is adjusted by way of wrapping sleeve gasket on FS final spice hanger bearing pin
Length, can influence according to construction environment and construction precision requirement is rapidly adjusted control, to ensure FS final spice bottom surface
High difference within the range of permission.
Preferably, some hangers are divided into two groups, two groups of hangers are arranged at its top surface front and rear sides along insertion axis,
Hanger group per side is along arranged in a straight line, and arranging line is vertical with FS final spice insertion axis, and so layout is not only improved to lift by crane and grasped
Make again because control adjusts.
Preferably, the quantity of each group of two groups of hangers is 2 or 4, can be set according to the size and lifting of FS final spice
Standby situation carries out selection setting.
Preferably, the sleeve gasket is multilayer, can so be realized by wrapping the sleeve gasket of varying number layer accurate
Adjustment.
Preferably, the set cushion material is high polymer material, operation and lighter in weight are both conveniently wrapped.
Preferably, bonding connection between the multilayer sleeve gasket, can be achieved the quick fixation to sleeve gasket.
Preferably, the sleeve gasket thickness in monolayer is 2-4 millimeters, it is easy to process to manufacture and wrap operation.
Preferably, the sleeve gasket width is equal with bearing pin face width, it is ensured that to the validity of lifting rope regulation.
Preferably, the bearing pin is tubulose, it is easy to fabricate and installs.
Preferably, being provided with screw thread on the bearing pin inner surface, it can conveniently be used for instrument and be dismantled under water.
Compared with prior art, a kind of immersed tube tunnel final joint of the utility model beneficial effect that can adjust hanging apparatus
Fruit：The influence of the high difference of bottom surface and by most when being lifted by measuring briny environment and hanging device in real time to FS final spice
The mode that sleeve gasket is wrapped on terminating head hanger bearing pin carrys out the covert effective length for adjusting lifting rope, can be achieved to FS final spice under water
Gesture stability during lifting, so that it ensures the high difference of FS final spice bottom surface within the range of permission.The utility model one
The adjustable hanging apparatus of kind immersed tube tunnel final joint, is not only simple in structure, easily operated control, and operating efficiency is high, applies
Work precision can reach grade.
