The course of work of the invention is as follows:
1, hydraulic motor travel motor 204 starts, and trolley starts along track travel, meanwhile, road nail nut 8 initially enters wedge-shaped guide plate In 401 guide groove, and it can be switched with detection trigger and provide " entrance of railway spike bolt " signal.Above-mentioned detection switch can be stroke and open Pass or close switch.
2, when road nail nut 8 is in contact with the inclined-plane of wedge-shaped guide plate 401, road nail nut 8 pushes wedge-shaped 401 edge of guide plate Y-direction is mobile, so that the straightway opening of wedge-shaped guide plate 401 is just aligned with road nail nut 8, at this point, Y-direction oil cylinder 305 is in Passive dragging working condition, when blocking the way nail nut 8 enters the straightway opening of wedge-shaped guide plate 401, the locking of Y-direction oil cylinder 305 is worked as Front position.
3, oil cylinder/cylinder 402 on Y-direction follower 4 stretches out, so that the extension of proximity sensor 403 and close road oncomelania 7 head of bolt.As trolley walks on, railway spike bolt 7 is entered in 403 detection range of proximity sensor, and sensor provides " road Nail contraposition completion " signal, trolley stop walking, and hydraulic motor travel motor 204 stalls, brake gear movement, the tight, locking by trolley brake On rail.
4, fastening hydraulic motor 601 starts turning, and the promotion oiling retention mechanism 6 of Z-direction oil cylinder 309 drops to the downlink of oil cylinder The dead point of journey, along with the rotation of hydraulic motor 601, Universal sleeve 6013 is inserted in nail nut 8.Along with fastening hydraulic motor 601 rotation, road nail nut 8 are gradually spun up, and nut pushes Universal sleeve 6013, transition sleeve 6012, operation axis 603 to move up, Simultaneously spring 6010 start to compress, when moving on to setting position on operation axis 603, can be switched with detection trigger, provide " back-out to Position " signal, then, fastening hydraulic motor 601 stop operating.Above-mentioned detection switch can be travel switch, close switch etc..
5, during 309 piston downlink of Z-direction oil cylinder, spring pressing plate 6018 comes into contact with the spring 9 of fastener, and with Continuing traveling downwardly for oil cylinder piston, spring pressing plate 6018 start under the action of spring 9, start the fixed hinge on valve seat 6017 Fulcrum rotation, drives injection valve 6016 to be swung, forms angle α between injection valve.
6, when nut, which " back-outs in place " signal, to be provided, injection valve 6016 is acted, and is sprayed with angle α to bolt head Oil, referred to as working position oil spout.
7, after the completion of lower working position oil spout, hydraulic motor 601 is rotated backward, and tightens nut 8.When trolley control system detects When reaching setting value to screw-down torque, hydraulic motor 601 stops operating, and Z-direction oil cylinder 309 drives oiling retention mechanism 6 on the whole It moves, meanwhile, Universal sleeve (63) is disengaged with road nail nut 8, and operation axis 603 is displaced downwardly to initial bit under the effect of spring 6010 It sets.
8, moving up with operation unit 3, spring pressing plate 6018 are gradually disengaged with spring 9, and injection valve 6016 is in bullet Under the action of spring 6015, initial attitude is returned, forms angle β between injection valve.
9, Z-direction oil cylinder 309 is promoted to up stroke dead-centre position, and injection valve 6016 is referred to as non-again to 7 head oil spout of bolt Working position oil spout.
10, the oil spout of inoperative position is completed, and brake gear discharges, and Y-direction oil cylinder 305 is switched to passive dragging working condition, row The starting of hydraulic motor 204 is walked, trolley enters next working cycles.
11, when using multiple-unit integration of operation, railway spike bolt 7 enters wedge-shaped guide plate 401, and triggers proximity sensor When 403, trolley stops walking, brake gear starting, at this point, due to the location error of railway spike, it cannot be guaranteed that all road oncomelanias Bolt 7 all just triggers the proximity sensor 403 of corresponding operation unit, at this point, being not detected " railway spike contraposition is completed " letter Number operation unit continue to move ahead in X under the promotion of oil cylinder 303, until railway spike bolt 7 triggers proximity sensor 403.
The content being not described in detail in this specification belongs to the prior art well known to those skilled in the art.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
