Shut-down mechanism 313 leans against truss-type steel 905, and (truss-type steel 905 extends along truss width direction, and along truss length direction interval
Be arranged) side；
(4) short transverse in adjustment stabilizer blade adjusting apparatus 2 adjusts stabilizer blade 205 and horizontal direction adjusts stabilizer blade 210, makes drawing
909 centering of line steel wire rope threads in the open threading hole of centering piece 305, after assembly tooling position adjusts, overturns arch
Clamp 225 makes C clamp 225 embrace the chord member of truss 904 of corresponding site, assembly tooling and staircase and girder 9 is fixed；
(5) driving of driving mechanism 403 overturns rollover stand 409 locks to sagging working condition, and by locking pin 411
The relative position of rollover stand 409 and holder 401；
(6) against the first lateral register face, it is corresponding against backbone 901 that the first side block adjusts pin 312 for the side of backbone 901
Positioning backbone 901 is embraced in the side at position using the first clamp 309；
(7) locating rack 418 is moved to the appropriate position along rollover stand 409, passes through self-positioning pin assemblies, stationary positioned framve 418
Position；
(8) backbone returns the side of rail 902 against the second lateral positioning surface, and the second side block adjusting pin nail 424 is returned against backbone
The side of 902 corresponding site of rail embraces positioning backbone using the second clamp 425 and returns rail 902；
(9) backbone 901 is bonded by centering guide 903 and backbone returns rail 902 and positions centering guide 903, be fixedly connected with centering guide
903 and staircase and girder 9, it is fixedly connected with centering guide 903 and backbone 901 and centering guide 903 and backbone returns rail 902；
(10) locking pin 411 for unclamping fixed rollover stand 409, under the action of driving mechanism 403, rollover stand 409 is overturn
To horizontal evacuation state, C clamp 225 is overturn, releases the fixation with truss；
(11) assembly tooling retracts on a small quantity, digs positioning shut-down mechanism 313, releases with truss-type steel 905 against releasing
The locking of pawl 321 and ratchet 318b, assembly tooling move down under the action of walking wheel along 901 walking of backbone, cross truss
After shaped steel 905, positioning shut-down mechanism 313 downwardly turns over, until positioning shut-down mechanism 313 is resisted against next truss-type steel 905
On, it carries out the backbone 901 of next position and backbone returns the assembly of rail 902.
