Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figures 1 to 6, a kind of carry formula integrated hydraulic rock drilling machine, comprise the bottom support 1 and drilling cramp 8 that are fixed to one another connection, the middle part of drilling cramp 8 is provided with the 7th bearing pin 19 that can connect with engineering truck oil cylinder and the 8th bearing pin 20 that can connect with engineering truck large arm.
Drilling cramp 8 is welded with parallel orbit 28, track 28 is provided with on the first slide plate 14, first slide plate 14 and has been bolted installing plate 13, installing plate 13 is fixed with the chuck 15 vertical with installing plate 13, be provided with hammer drill 12 in chuck 15, hammer drill 12 is connected with drilling rod 7.
The top of drilling cramp 8 is provided with drive sprocket 16, bottom is provided with driven sprocket 10.Drive sprocket 16 and driven sprocket 10 are combined with open loop chain 17.The first end 17a of open loop chain 17 walks around drive sprocket 16 and is fixedly connected with installing plate 13 with by chain card 18 afterwards, is fixedly connected with after the second end 17b walks around driven sprocket 10 by chain card with installing plate 13.
Backplanes support 1 is fixed with the dust guard 3 parallel with chuck 15, dust guard 3 is provided with the via hole 3a passed through for drilling rod 7.Dust guard 3 is hinged with relative first by the first bearing pin 30a and the second bearing pin 30b grab bar block 4a and second and grab bar block 4b, first grabs bar block 4a and second grabs bar block 4b and is provided with the cambered surface corresponding with drilling rod 7 profile.
The both sides of dust guard 3 are hinged with the first oil cylinder 6a and the second oil cylinder 6b by the 3rd bearing pin 31a and the 4th bearing pin 31b.First to grab bar block 4a hinged by the piston rod of the 5th bearing pin 5a and the first oil cylinder 6a, and second to grab bar block 4b hinged by the piston rod of the 6th bearing pin 5b and the second oil cylinder 6b.
Guide rail 28 is combined with on the second slide plate 33, second slide plate 33 in the below of the first slide plate 14 and is fixed with the support set 11 coordinated with drilling rod 7.Second slide plate 33 is fixed with pull bar 21, and pull bar 21 coordinates with nut 34 through after the preformed hole on the first slide plate 14.The diameter of preformed hole is greater than the diameter of pull bar 21.Guide rail 28 is provided with the block 35 for limiting the second slide plate 33 lower end limit travel.
The bottom of drilling cramp 8 is fixed with clutch shaft bearing box installing rack 36a and the second bearing box installing rack 36b.Clutch shaft bearing box installing rack 36a is relatively set with the first bolt 9a and the second bolt 9b up and down, is provided with clutch shaft bearing box 23a between the first bolt 9a and the second bolt 9b, is provided with clutch shaft bearing 22a in clutch shaft bearing box 23a.
Second bearing box installing rack 36b is relatively set with the 3rd bolt 9c and the 4th bolt 9d up and down, is provided with the second bearing box 23b between the 3rd bolt 9c and the 4th bolt 9d, is provided with the second bearing 22b in the second bearing box 23b.The sprocket shaft 29 of driven sprocket 10 is supported by clutch shaft bearing 22a and the second bearing 22b.
The top of drilling cramp 8 is provided with and advances mount pad 24, advances on mount pad 24 and is fixed with tie-plate 26, tie-plate 26 is provided with motor 27.Drive sprocket 16 is arranged on the power transmission shaft 32 of motor 27, and by pressing plate 25 and the 5th bolt axial location.
Rock drilling drilling cramp being connected with engineering truck oil cylinder by the 7th bearing pin 19, is connected with engineering truck by the 8th bearing pin 20, therefore by regulating the flexible of engineering truck oil cylinder, drilling cramp 8 being rotated around the 8th bearing pin 20, thus the angle of adjustment drilling cramp.After drill bit 2 is connected with drilling rod 7, hotwire 27 and hammer drill 12, can start rock drilling boring work.By controlling the rotating of motor 27, thus make chain 17 clockwise or counterclockwise movement, and then realize the first slide plate 14 and move upward or move downward.When grabbing pricker, first grabs bar block 4a is opened around the first bearing pin 30a rotation by the piston rod retraction of the first oil cylinder 6a, and second grabs bar block 4b is opened around the second bearing pin 30b rotation by the piston rod retraction of the second oil cylinder 6b; Connect pricker when completing, the piston rod of the first oil cylinder and the second oil cylinder stretches out, thus makes first to grab bar block 4a and second to grab bar block 4b and close.
In the process of boring, first slide plate 14 is at the moved downward of chain 17, second slide plate 33 moves downward under gravity, in initial motion process, due to the requirement according to actual condition, the rotating speed of motor 16 is lower, and therefore the movement velocity of the first slide plate 14 is comparatively slow, and the first slide plate 14 and the second slide plate 33 are in the state of roughly geo-stationary.When the second slide plate 33 moves downward extreme position, by stop motion under the effect of block 35, the first slide plate 14, under the effect of chain 17, can continue to move downward, and hammer drill 12 continues rock drilling boring, until the first slide plate 14 contacts with the second slide plate 33.In whole process, support set 11 will be in the middle part of drilling rod 7 all the time, thus avoids drilling rod 7 to bend because suffering larger impact force.
If desired adjust loose chain 17, only need, by the degree regulating the first bolt 9a, the second bolt 9b, the 3rd bolt 9c and the 4th bolt 9d to be screwed into bearing box installing rack, clutch shaft bearing box 23a and the second bearing box 23b be moved upward; To tighten chain, tighten process contrary.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
