2. main frame contraposition, a upper hydraulic leg, trolley proceeds to horn front end (such as Figure 14 A).The hanger rail shoulder pole descends.By the front and back oscillating arm mechanisms, adjust horn position, hanger rail shoulder pole and track switch contraposition.
4. press 3600mm spacing locking track switch with the soft rope of nylon, and lifting track switch.By the front and back oscillating arm mechanisms, adjust horn return centering (such as Figure 14 B).
5. the trolley reversion is to horn afterbody (such as Figure 14 C), and the hanger rail shoulder pole descends, and track switch falls within on the main frame guide rail loopback automatic mechanism (such as Figure 14 D).
6. subsidiary engine and main frame contraposition starts guide rail loopback automatic mechanism, and track switch is transmitted back on the subsidiary engine guide rail loopback automatic mechanism (such as Figure 14 E).
7. subsidiary engine transports track switch to the frame that changes the outfit (such as Figure 14 F), the frame that the changes the outfit track switch (such as Figure 14 G) of slinging, and subsidiary engine withdraws from the frame that changes the outfit (such as Figure 14 H).
8. locomotive pushes flatcar and enters the frame that changes the outfit, and track switch falls within on the flatcar, and the locomotive traction flatcar rolls the frame that changes the outfit away from.
9. main frame is packed up hydraulic leg, retreats contraposition.Repeat 1-8, until the recovery of ABC three part track switches is complete.
The step of lay-up operation is as follows:
10. main frame contraposition, a upper hydraulic leg, main frame is positioned at the shop state for the treatment of (such as Figure 15 A).
11. locomotive pushes the flatcar that new track switch is housed and enters the frame that changes the outfit, the frame that the changes the outfit track switch of slinging, and the locomotive traction flatcar rolls the frame that changes the outfit away from.
12. subsidiary engine enters the frame that changes the outfit (such as Figure 15 B), the frame whereabouts track switch (such as Figure 15 C) on subsidiary engine that changes the outfit, subsidiary engine transportation track switch and main frame contraposition (such as Figure 15 D).
13. start the main frame traction system, track switch enters main frame, subsidiary engine returns (such as Figure 15 E).
14. trolley is at the horn afterbody, the hanger rail shoulder pole descends, and presses 3600mm spacing locking track switch with the soft rope of nylon, and lifting track switch (such as Figure 15 F).
15. trolley moves ahead, hanger rail shoulder pole decline (such as Figure 15 G).By the front and back oscillating arm mechanisms, adjust the horn position, the track switch contraposition.Track switch is laid complete, and the hanger rail shoulder pole rises, and by the front and back oscillating arm mechanisms, adjusts horn return centering (such as Figure 15 H), and the trolley reversion is to the horn afterbody.
16. main frame is packed up hydraulic leg, moves ahead, and contraposition, a upper hydraulic leg, main frame is positioned at the shop state for the treatment of.Repeat 11-15, until the laying of ABC three part track switches is complete.
It is evident that, above description and record only are for example rather than in order to limit disclosure of the present invention, application or use.Although described in an embodiment and be described in the drawings embodiment, but the optimal mode that the present invention does not limit by the accompanying drawing example and the conduct of describing is in an embodiment thought at present to be implementing the specific examples of instruction of the present invention, and scope of the present invention will comprise any embodiment of the manual that falls into the front and appended claim.
