The principles of the present invention and application method are as follows: after bus duct fixes in mounting bracket, installing
Bracket fixes hoist steel cable and safety rope close to one end of column, starts hoist engine, and slowly run because movable pulley vehicle with
Kinematics and static friction coefficient between ground and track will not be zero, it follows that it is desirable that starting, which is equipped with the mounting rack of bus duct,
One maximum static friction force, hoist engine starting drives bracket uplink by wirerope, and bracket does not reach vertical line at this time,
Its force analysis is shown in attached drawing 1, and when the F2 in attached drawing 1 is greater than maximum static friction force, bus duct bracket starts to move, and bracket moves
During dynamic, because there is huge weight, bracket can be made by vertical line by the inertia during tethered sliding, become
State shown in attached drawing 2, the power in attached drawing 2
F2=Fsin α (formula 1)
As bracket is more and more big by the angle [alpha] of vertical line, from formula 1 as can be seen that in the case where F is constant,
F2 also can be more and more big, and F2 moves ahead contrary with bracket, he can prevent bracket from continuing forward and make bracket with hoist engine
Pulling force moves up, above-mentioned to overcome stiction and the behavior for preventing inertia excessive that be alternately present during bracket lifts by crane,
It is carried until bus duct reaches perpendicular to the operating condition on ground until the bracket for being fixed with bus duct, is loaded with the bracket of bus duct at this time
It is perpendicular to the ground, by known to formula 1:
F=F1, F2=0.
Hoist engine stops traction, and bus duct no longer moves, and fixes safety rope.
After the test to bus duct, starting hoist engine puts down wirerope, and referring to attached drawing 2, hoist engine is led stress at this time
The angle drawn between wirerope and vertical line becomes larger, according to formula 1 it is found that F2 increases, when F2 is greater than movable pulley vehicle and ground steel
When the stiction of rail, bracket starts mobile return, also due to bracket can be moved to state shown in attached drawing 1 the reason of inertia
After stop, when F2 is less than the kinematics and static friction power of movable pulley vehicle and ground rail, bracket stops movement, and hoist engine continues to put down
Bracket, as bracket is more and more big by the angle [alpha] of vertical line, according to formula 1 it is found that F2 increases, when F2 is greater than movable pulley vehicle
When with the stiction of ground rail, bracket is continued to move to, and so on until horizontal position；It, can also in the other end of bracket
Start the bracket under plumbness with manpower, so that mobile deflecting roller vehicle is mobile, so that bracket, which slowly deviates, vertically moves shape
State, when bracket deviates plumbness, from force analysis attached drawing 2 as can be seen that when F2 is greater than the stiction of mobile bracket
When, mobile bracket oneself will utilize the gravity of bracket itself mobile away from the direction of upright steel structure, until most moving back
It moves until the horizontality most started.In bracket moving process, another four-wheel wheel vehicle can be placed on bracket in the following,
To bear weight support frame jointly under horizontality.
