It is fixed at respectively on two cast-in-situ box girders, Hanging Basket is slidably connected by linear advancement mechanism and two walking rails, and Hanging Basket
It is sheathed on simultaneously on two cast-in-situ box girders.
Linear advancement mechanism is respectively equipped with described two walking rails, linear advancement mechanism includes hoist engine, wirerope, card
Button steel piston shoes and fixed pulley, buckle steel piston shoes are slideably positioned on walking rails along the length direction of walking rails, Hanging Basket and card
Button steel piston shoes are fixedly connected, and hoist engine and fixed pulley are respectively arranged on walking rails both ends, and wirerope one end is connected with hoist engine, another
End is directly connected with Hanging Basket or is connected afterwards with Hanging Basket around fixed pulley.
The Hanging Basket includes two groups of shoulder pole girder groups be arrangeding in parallel, and shoulder pole girder group includes being parallel to each other and same vertical flat
Upper shoulder pole girder and lower shoulder pole girder in face, upper shoulder pole girder are located above cast-in-situ box girder, and lower shoulder pole girder is located at below cast-in-situ box girder, on
Shoulder pole girder is connected with lower shoulder pole girder by vertical distance adjusting means, and closure segment is provided between the lower shoulder pole girder of two shoulder pole girder groups
End template and skeleton.
The vertical distance adjusting means are the first fining twisted steel and auxiliary jack.
The walking rails are fixedly connected by the second fining twisted steel in cast-in-situ box girder of nuzzling in advance with cast-in-situ box girder.
The fixed pulley is arranged on the counter-force skeleton for being fixed on walking rails end.
The utility model is this have the advantage that due to the structure：It can be put in railway in stipulated time section, most quickly
Degree completes the reach of Hanging Basket or retracts work, avoids to greatest extent because cross-line is constructed to existing railway etc. across lower works
Caused by influence, be effectively guaranteed existing railway operation etc. across lower works safety, two rack winches connections during operation
Same operating platform, can assume unified command of, simultaneously operating, Hanging Basket both sides move forward with fall back process in can synchronous shift, gram
It is more as operating personnel in the trailer system of suspended basket artificial jack, jack are taken, it is difficult to which simultaneously operating, Hanging Basket both sides are difficult
The deficiencies of with synchronizing moving, the suspended basket leapfrog problem caused by hand fit is uncoordinated is avoided, improve work effect
Rate, reduce to existing bridge etc. across lower works interference, reduce construction cost, shorten the construction period, improve extension
The security and stability of basket traveling.
