The working process of the invention is as follows:
1. the traveling hydraulic motor 204 is started, the trolley starts traveling along the track, and at the same time, the spike nut 8 starts to enter the guide groove of the wedge-shaped guide plate 401, and the detection switch can be triggered to give a spike bolt entering signal. The detection switch may be a travel switch or a proximity switch.
2. When the spike nut 8 contacts with the inclined surface of the wedge-shaped guide plate 401, the spike nut 8 pushes the wedge-shaped guide plate 401 to move along the Y direction, so that the opening of the straight line section of the wedge-shaped guide plate 401 is just aligned with the spike nut 8, at the moment, the Y-direction oil cylinder 305 is in a passive dragging working state, and when the spike nut 8 enters the opening of the straight line section of the wedge-shaped guide plate 401, the Y-direction oil cylinder 305 locks the current position.
3. The cylinder 402 on the Y-direction follower 4 extends so that the proximity sensor 403 extends forward and is close to the head of the blind bolt 7. As the trolley continues to walk, the spike bolt 7 enters the detection range of the proximity sensor 403, the sensor gives a spike alignment completion signal, the trolley stops walking, the walking hydraulic motor 204 stops running, and the brake device acts to brake and lock the trolley on the steel rail.
4. The tightening hydraulic motor 601 starts to rotate, the Z-direction oil cylinder 309 pushes the oiling tightening mechanism 6 to descend to the down stroke dead point of the oil cylinder, and the universal sleeve 6013 is sleeved into the spike nut 8 along with the rotation of the hydraulic motor 601. With the rotation of the tightening hydraulic motor 601, the spike nut 8 is gradually screwed up, the nut pushes the universal sleeve 6013, the transition sleeve 6012 and the working shaft 603 to move upwards, the spring 6010 starts to compress, and when the working shaft 603 moves upwards to a set position, a detection switch can be triggered to give a 'screwing out in place' signal, and then the tightening hydraulic motor 601 stops rotating. The detection switch may be a travel switch, a proximity switch, or the like.
5. When the piston of the Z-direction cylinder 309 descends, the spring strip pressing plate 6018 starts to contact the spring strip 9 of the fastener, and along with the continuous descending of the piston of the cylinder, the spring strip pressing plate 6018 starts to rotate along the fixed hinge pivot on the valve seat 6017 under the action of the spring strip 9, so as to drive the injection valve 6016 to swing, and an included angle alpha is formed between the injection valves.
6. When the nut is unscrewed in place, the injection valve 6016 acts to inject oil into the head of the bolt at an included angle alpha, which is called working position oil injection.
7. After the oil injection at the lower working position is completed, the hydraulic motor 601 rotates reversely, and the nut 8 is screwed. When the trolley control system detects that the tightening torque reaches the set value, the hydraulic motor 601 stops rotating, the Z-direction oil cylinder 309 drives the oiling and fastening mechanism 6 to move upwards as a whole, meanwhile, the universal sleeve (63) is separated from contact with the spike nut 8, and the working shaft 603 moves downwards to the initial position under the action of the spring 6010.
8. Along with the upward movement of the working unit 3, the elastic strip pressing plate 6018 gradually breaks away from contact with the elastic strip 9, and the injection valve 6016 returns to the initial posture under the action of the spring 6015, so that an included angle beta is formed between the injection valves.
9. The Z cylinder 309 is lifted to the upper stroke dead point position, and the injection valve 6016 injects the head of the bolt 7 again, which is called off-position injection.
10. The non-working position oil injection is completed, the brake device is released, the Y-direction oil cylinder 305 is switched to a passive dragging working state, the walking hydraulic motor 204 is started, and the trolley enters the next working cycle.
11. When multi-unit combined operation is adopted, spike bolts 7 enter wedge-shaped guide plates 401, when proximity sensors 403 are triggered, the trolley stops running, a brake device is started, at the moment, due to position errors of spikes, all spike bolts 7 can not be guaranteed to just trigger the proximity sensors 403 of corresponding operation units, at the moment, operation units which are not detected with spike alignment completion signals continue to move forward under the pushing of X-direction oil cylinders 303 until the spike bolts 7 trigger the proximity sensors 403.
What is not described in detail in this specification is prior art known to those skilled in the art.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
