Hereinafter, the operating relationship of the pneumatic combination drilling device 1 according to the present invention.

 Move the crane 1 to a predetermined place (slope), extend the boom 2, the hydraulic pneumatic combination drilling device (1) according to the present invention is located in a specific portion of the surface pneumatic combination drilling device ( Activate 1).

The angle adjustment cylinder 13 is operated to keep the operating plate 11 and the work table 16 inclined forward, as shown in FIG.

With the worktable 16 held horizontally, the front frame 18 and rear cylinder 19 are operated to raise the track frame 25, with the bit 41 mounted at the tip of the rod 40 being the slope of the slope. It is raised to be located at a predetermined part.

When the front and rear cylinders 22 are operated in a state in which the bit 41 mounted at the tip of the rod 40 together with the track frame 25 is raised to a predetermined height, the guide rail fixed to the bottom of the work table 16 is provided. (15) is moved forward (moving) while sliding along the guide block 14 fixed to the operating plate (11), the work table 16 together with the guide rail (15) to move forward (move), the work table 16 When the () is advanced, the fixing pin 36 fixed to the front end of the track frame 25 is stuck to a specific portion of the slope and is maintained in a fixed state.

As the track frame 25 moves forward by the operation of the forward and backward cylinder 22 as described above, a device for driving and fixing the fixed pin 36 on a slope is well known, and thus a detailed description thereof will be omitted.

Drilling hydraulic motor (60) from the hydraulic unit (5) and the air unit (not shown specifically) in a state in which the fixed pin 36 fixed to the front end of the track frame 25 is fixed to the specific portion of the slope By supplying hydraulic pressure and pneumatic pressure to the rotary processing unit 65, drilling and hammering and flashing work are carried out as follows.

In the drilling operation, the hydraulic unit 5 is operated to supply hydraulic pressure to the drilling hydraulic motor 60, and at the same time, the chain 29 is idled (advanced) by operating the forward and backward hydraulic motor 27 to operate the hydraulic pneumatic combination unit. Drilling operation is carried out while advancing the rod 40 and the bit 41 together with the 50.

As described above, when the pneumatic combination unit 50 moves forward, the side support rollers 53 and the bottom support rollers 54 which are axially installed on the bottom edge of the moving plate 510 and the side support 52 are track frames 25. Rolling while supporting along the side and bottom of the guide rail 26 fixed to the hydraulic pneumatic combination unit 50 is to move smoothly without being separated from the track frame (25).

When the hydraulic pressure is supplied and the drilling hydraulic motor 60 is operated, the starting bracket 63, the rotating union unit 65, the anti-vibration flange 65, and the interlocking portion 76 rotate together with the rotation shaft 62. While rotating the rod 40 mounted on the interlocking shaft 79, when the rod 40 is rotated, the bit 41 is rotated.

When the forward and backward hydraulic motor 27 is operated while the bit 41 is being rotated together with the rod 40, the sprocket 28-1 rotates while the chain 29 is engaged with the sprocket 28. ) Is revolved (advanced), and when the chain 29 is advanced, the pneumatic combination unit 50 which is operated together with the moving plate 51 fixed to the chain 29 is advanced, the pneumatic pneumatic combination unit 50 As it moves forward, the rotating rod 40 and the bit 41 move forward to drill holes at specific positions on the slope.

(65) and the rod 41 and the bit 41 is supplied to the rod 41 and the bit 41 through the air distribution hole (69-1) drilled in the interlocking portion 76 to perform the hammer and flashing operation, the hammer and flashing operation Since it is usually carried out more detailed description will be omitted.

As described above, the vibration and shock generated when the drilling operation and the hammer and flashing operation are performed are transferred to the pneumatic combination unit 50 through the rod 40, and the vibration and shock transferred to the pneumatic combination unit 50 are interlocked. Vibration and shock transferred from the part 76 to the anti-vibration flange portion 70, the vibration and shock transferred to the anti-vibration flange portion 70 is the binding flange 72 of the interlocking flange 77 and the connection bracket 73 of the interlocking portion 76. Absorbed by the anti-vibration pad disks 75, which are squeezed between the ()) and extinguished, so as not to be transferred to the rotational union unit (65).

Therefore, the vibration and shock generated during the drilling and hammering and flashing operations are absorbed by the dustproof pad discs 75 when transferred to the pneumatic combination unit 50 so that they are not transmitted to the drilling hydraulic motor 60 for drilling. The perforated hydraulic motor 60 can be protected.

As described above, the rod 40 and the bit 41 move forward together with the pneumatic combination unit 50 to perform the drilling operation. When the drilling operation is completed, the operation of the air unit is stopped. The hydraulic motor 60 is operated in reverse to rotate the rod 40 and the bit 41 at the same time, and at the same time, the reverse hydraulic motor 27 is operated in reverse to operate the rod 40 and the rod 40 together with the hydraulic pneumatic combination unit 50. When the bit 41 is reversed, the bit 41 can be easily taken out (discharged) from the hole drilled in the slope.

When the bit 41 is completely drawn out from the hole drilled on the slope, the operation of the forward and backward hydraulic motor 27 and the drilling hydraulic motor 60 is completely stopped to stop the reverse and reverse rotation, and the forward and backward cylinder 22 is reversed. The track frame 25 is retracted with the work table 16 to be pulled out and the fixed pin 36 is pulled out from the inclined surface to release the fixed (detained) state.

In a state in which the crane 1 is moved while the fixing pin 36 is released, or the front cylinder 18 and the reverse cylinder 19 are operated in reverse to lower the work bench 16. The crane 1 is moved to the next drilling position, and the drilling operation as described above is repeatedly performed after the movement of the crane 1 is completed.
