Description
Technical field
The utility model is related to bridge construction auxiliary mould technical fields, more particularly, to one kind in suspension bridge construction
Cable crane lifting trailer system.
Background technology
Suspension bridge is widely used in a variety of applications as Long span bridge type instantly.In the lifting construction of stiffening girder of suspension bridge
Equipment usually has two kinds of deck unit erection gantry, cable crane, deck unit erection gantry to be divided into hoist type deck unit erection gantry and hydraulic jack formula cable
Carry loop wheel machine.Deck unit erection gantry is big by bridge location landform limiting factor, and limitation is big.Cable crane is economic, practical as one kind, efficiently hangs
Install it is standby, modern suspension construction in it is widely used.Cable crane has span ability big, and elevating capacity is strong, overall structure letter
The advantage single, speed of application is fast, security risk is small.Substantially it is not limited by bridge location landform, may span across the obstacles such as great rivers, deep valley
Object has the characteristics that positioning accuracy is high, movement is flexible, superior especially suitable for the engineering that mountain area and logical river cannot suspend traffic
Property is stronger.
Conventional cable hang traction, tackling system as shown in Figure 1, traction rope 200 from 100 rope stretching of rack winch, through anchorage
300, the deflecting roller at pylon 400 and sport car 500 turns to, and tail of rope is anchored on built-in fitting, and respectively setting one is led for single width two sides
Draw hoist engine, left and right each two sets of independent trailer systems of width.Hoisting line turns from the hoisting winding rope stretching of a bank through tower top
It is turned through the upper and lower hanger of sport car to wheel, is anchored by built-in fitting at another bank anchorage, left and right each a set of independence of width
Tackling system.By a bank rack winch rope closing, another bank rack winch Synchronous Radio rope realizes the traction of sport car, lifting
The folding and unfolding of hoist engine manipulates the weight lifting on lower hanger.Such winding mode exists as following drawbacks：(1) traction is rolled up
The manipulation request for raising machine is relatively high, the phenomenon " to drawing " easily occurs；(2) underaction is controlled to lift heavy object, precision is relatively low；(3) to volume
It is relatively high to raise machine natural rate of interest requirement, any hoist engine system that breaks down will be unable to operate.
