Wherein, first flexible actuating mechanism includes first hydro-cylinder 21, the left end and the slide 3 of first hydro-cylinder 21 are connected, the right-hand member of first hydro-cylinder 21 is connected with the right-hand member of balladeur train 2, slides right through first hydro-cylinder 21 drive slide 3 to drive down-the-hole drilling rod 6 and stretch out the balladeur train 2 and stretch into drilling. The second telescopic driving mechanism comprises two second oil cylinders 11, the two second oil cylinders 11 are symmetrically arranged on two sides of the length direction of the sliding frame 2, the left end of each second oil cylinder 11 is connected with the left end of the base, the right end of each second oil cylinder 11 is connected with the right end of the sliding frame 2, and the sliding frame 2 is driven to slide rightwards integrally through the second oil cylinders 11 so as to further increase the extension length of the down-the-hole drill rod 6.
The drill floor is installed on the existing heading machine, when a heading drill bit is influenced by a hard rock mass to cause difficulty in feeding, the drilling is quitted, the down-the-hole drill floor is switched, the down-the-hole drill rod is driven to stretch into the drilling hole through the first telescopic driving mechanism and/or the second telescopic driving mechanism, the down-the-hole drill bit is abutted to the hard rock mass, the hydraulic impactor is started again, the down-the-hole drill bit impacts and breaks the hard rock mass, then the heading drill bit is switched again to continue heading operation, the heading capacity and the heading efficiency of the heading machine are improved, and the construction period is shortened.
Example two:
in a further improvement of the first embodiment, referring to fig. 3 to 6, a clamping portion 41 is disposed on a side of the supporting seat 4 facing the sliding seat 3, the clamping portion 41 is hollow, at least three rollers 411 are uniformly distributed on an inner wall of the clamping portion 41 along a circumferential direction of the down-the-hole drill rod 6, and the three rollers 411 respectively abut against an outer circumference of the down-the-hole drill rod 6. The pipe is clamped together by a plurality of rollers 411, on the one hand forming a support point in the middle or at the end of the pipe remote from the hydraulic impactor 5 to provide a firm support force, and on the other hand reducing the frictional resistance by the rollers 411 being in rolling contact with the outer wall of the pipe.
Obviously, in order to guarantee the rolling smoothness of roller 411, roller 411 needs to be connected with clamping part 41 through the bearing rotation, and drilling rod when stretching into the drilling, when the drill bit strikes the rock body and in the drilling rod recovery process, inevitably at debris such as drilling rod outer wall adhesion mud, rubble, grit, if make the drilling rod outer wall that adheres to debris directly slide through clamping part 41, debris easily aggravate the wearing and tearing of roller 411 and debris easily invade clamping part 41 inner wall and damage the bearing. Therefore, in this embodiment, one side of the support seat 4 away from the slide seat 3 is provided with a deslagging portion 42, the deslagging portion 42 includes a frustum 421 and a taper sleeve 422, one end of the frustum 421 is connected with the support seat 4, and the other end of the frustum 421 is in threaded connection with the taper sleeve 422, so that the frustum 421 and the taper sleeve 422 are spliced into a circular truncated cone. Preferably, the outer wall of the taper sleeve 422 on the side facing the frustum 421 is further provided with a mounting hole 4223, and in order to ensure that the taper sleeve 422 is screwed, fastened and conveniently detached, the mounting hole 4223 is provided so that tools such as crowbars can extend into the mounting hole, and the arm of force is increased so that the taper sleeve 422 can be screwed conveniently. Through set up taper sleeve 422 in supporting seat 4 keep away from clamping part 41 one side, when the drilling rod retracts and accomodates, scrape the adnexed debris of drilling rod outer wall through taper sleeve 422 front end to realized the protection to clamping part 41. Specifically, clamping part 41 runs through towards slide 3 one side and is equipped with a plurality of through-holes 412, supporting seat 4 runs through towards slide 3 one side and is equipped with a plurality of guide holes 43, frustum 421 is equipped with a plurality of screw holes 4211 towards slide 3 one side, through-hole 412, guide hole 43 with screw hole 4211 one-to-one, through the screw pass through-hole 412 with behind the guide hole 43 with screw hole 4211 threaded connection to the realization is fixed clamping part 41 and slagging-off portion 42 on supporting seat 4.
As a further improvement to the above solution, referring to fig. 5-6, a graphite sleeve 4222 is further disposed between the frustum 421 and the taper sleeve 422, and an inner wall of the graphite sleeve 4222 abuts against an outer wall of the down-the-hole drill rod 6. In order to avoid the expansion and contraction of the drill rod interfered by the taper sleeve 422, a safety gap needs to be reserved between the inner wall of the taper sleeve 422 and the outer wall of the drill rod, namely, fine gravel possibly enters the safety gap, the graphite sleeve 4222 is arranged in the taper sleeve 422 to form a second defense line for blocking sundries, and the expansion and contraction freedom of the drill rod can be guaranteed even if the graphite sleeve 4222 is attached to the outer wall of the drill rod due to the small friction coefficient of graphite.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
