Through the arrangement, the lifting motor 23 is utilized to drive the driving plate 22 to continuously rotate so as to drive the driving arm 221 to continuously rotate along with the driving plate 22, after the driving arm 221 contacts with the lifting platform 211 of the lifting piece 21, the driving arm 221 is lifted up through the lifting platform 211, the lifting piece 21 is indirectly lifted up, then the drilling bit 2 is indirectly lifted up, after the drilling bit 2 contacts with the top of a tunnel and penetrates, the drilling bit 2 is relatively fixed with the top of the tunnel, the vehicle body 1 continuously moves forwards, at the moment, the sliding seat 20 passively slides along the compensation sliding rail 10, the elastic reset piece 11 is stretched/extruded in the process until the driving arm 221 is separated from the lifting platform 211, and when the driving arm 221 is separated from the lifting platform 211, the lifting piece 21 (and the drilling bit 2 thereon) rapidly descends under the action of gravity, so that the drilling bit 2 is rapidly separated from the top of the tunnel, and the elastic reset piece 11 drives the sliding seat 20 to reset at the moment, the mechanism enables the lifting piece 21 to have stable lifting performance and simultaneously have rapid descending performance, the stable lifting performance can ensure smooth proceeding of the drilling process, the rapid descending performance can be guaranteed, the rapid descending performance can be completed along the direction of the compensation sliding rail 10, and the time of the rapid descending performance can be relatively reduced, and the time of the drilling bit 2 can be rapidly separated from the top of the tunnel can be rapidly separated from the top along the sliding rail 20.
It should be noted that, the lifting platform 211 has a certain length along the extending direction of the compensating slide rail 10, and meanwhile, the length of the shifting arm 221 also has a sufficient length, that is, even if the sliding base 20 passively slides to approach the far end (left end in the drawing) of the compensating slide rail 10, the shifting arm 221 still can be in contact with the lifting platform 211, and the lifting platform 211 is lifted, specific parameters can be designed according to actual requirements and actual conditions, meanwhile, the moving speed of the vehicle body 1 also needs to be matched, and only needs to ensure that the sliding base 20 cannot move to the final end (left end in the drawing) of the compensating slide rail 10 in the period lifting process of the lifting piece 21.
With further reference to fig. 3 to 7, in order to ensure the full execution of the punching operation, the lifting member 21 is provided with a positioning table 212 in a protruding manner, the slide base 20 is hinged with a trigger 201 in a shaft manner, and when the lifting member 21 is lifted to the highest position, the trigger 201 can be engaged with the positioning table 212; the trigger 201 is connected with a force-unloading rod 2011, the driving plate 22 is connected with a driving plate 222, and the driving plate 222 is used for periodically driving up the force-unloading rod 2011 so as to separate the trigger 201 from the positioning table 212, so that the lifting piece 21 is periodically lowered.
