6
), track space be exactly railcar (
1
) steel wheel (
10
) span, install simultaneously fixed pulley (
2
), traction apparatus (
3
) and steel wire rope (
4
), will front and back two railcars (
1
) steel wheel (
10
) be placed in track (
6
On), then with the two of construction site cranes (
5
) by two bridge plates (
14
Before and after) two lift two railcars of front and back (
1
) girder (
11
On), Jiang Kaliang (
7
) be placed on two bridge plates (
14
On), by two, left and right bolt (
8
) be screwed into Ka Liang (
7
) internal thread hole in, by two bridge plates (
14
) upper end clamp temporarily, start traction apparatus (
3
), steel wire rope (
4
) the front railcar of drive (
1
) move right, when bridge plate (
14
) front end movement to horizontal plane and slope intersection time, need to start before and after's railcar (
1
) multistage jack (
12
), make two bridge plates (
14
) can pass through, when two bridge plates (
14
) have been enter into abutment (
16
), will enter gantry crane (
21
) time, the front railcar of decline (
1
) multistage jack (
12
), railcar after rising (
1
) multistage jack (
12
), make two bridge plates (
14
) be substantially at level, be further continued for drawing steel wire rope (
4
), make two bridge plates (
14
) front end enter gantry crane (
21
) in, with gantry crane (
21
) suspender by two bridge plates (
14
) front end sling, rear railcar (
1
) deactivate, by gantry crane (
21
) and rear railcar (
1
) continue by two bridge plates (
14
) it is transported to installation position.

Detailed description of the invention
Summary of the invention has been described in detail the detailed description of the invention of the present invention, is not repeated herein, and need to be described as follows: one

See figure
1
, typically approach ramp (
15
) left side arrange bridge plate (
14
) prefabricated place
,
Prefabricated place be provided with two cranes (
5
)
,
By two cranes (
5
) prefabricated place infantile tic ship defeated bridge plate (
14
);When bridge plate (
14
) front end movement to horizontal plane and slope intersection time, need to rise front railcar (
1
) multistage jack (
12
), make two bridge plates (
14
) front end on rise, pass through at slope;Equally when two bridge plates (
14
) have been enter into abutment (
16
), will enter gantry crane (
21
) time, the front railcar of decline (
1
) multistage jack (
12
), railcar after rising (
1
) multistage jack (
12
), make two bridge plates (
14
) be substantially at level, so can enter smoothly gantry crane (
21
In).Two
.
See figure
4
, railcar (
1
) should design as far as possible lower, railcar (
1
) be designed to the highest, gantry crane (
21
) increase the most therewith, unnecessary waste can be caused;Design Ka Liang (
7
) purpose be to ensure that two bridge plates (
14
) steady during rising and declining, it is unlikely to topple.Three

, the present invention by two bridge plates (
14
) transport together, be to cooperate with gantry crane (
21
) work, track (
6
) spacing need corresponding Aided design, same railcar (
1
) also need corresponding Aided design.Four

.
Summary of the invention be only described in detail two bridge plates (
14
) movement method at slope, on the most mounted bridge plate face, movement situation is the most simply too much, because the most mounted bridge plate face is substantially at level, movement work is the most permissible by normal method.
