The bottom surface of the lower movable seat 26 is pressed against the top surface of the corresponding middle support beam 27, and the side support frame 261 is at the front or rear side of the middle support beam 27. The positioning pin shaft 262 is clamped in the corresponding connecting and positioning through hole and the positioning through hole, which can ensure the fixation of the lower movable seat 26. The positioning pin shaft 262 can be removed from the corresponding connecting and positioning through hole and the positioning through hole by knocking hard to achieve disassembly.

[0042] Furthermore, the front part of the lower movable seat 26 is movably connected to the connecting seat of the pushing cylinder 28 through a bearing, and the front end of the push rod of the pushing cylinder 28 is movably connected to the movable fixed seat 29 through a bearing, and the movable fixed seat 29 is installed on the corresponding middle support beam 27.

[0043] The mobile fixing base 29 comprises a bottom plate and side fixing plates fixed on the top surface of the left and right parts of the bottom plate, a turnover positioning plate 291 is between the two side fixing plates, a central rotating shaft is inserted into the central through hole of the turnover positioning plate 291, the front and rear ends of the central rotating shaft are fixed on the two side fixing plates, and the bottom of the turnover positioning plate 291 is inserted into the corresponding slot in the top plate of the corresponding middle supporting beam 27.

[0044] The front and rear sides of the upper part of the turnover positioning plate 291 are provided with limiting pins 292, the left and right parts of the limiting pins 292 are inserted into the corresponding insertion holes in the two side fixing plates, and the front and rear side walls of the upper part of the turnover positioning plate 291 are close to or abut against the side walls of the corresponding limiting pins 292.

[0045] Further, the middle parts of the inner side walls of the two side fixing plates are fixed with intermediate reinforcing plates, the left and right parts of the central rotating shaft are clamped on the inner side walls of the central through holes of the corresponding intermediate reinforcing plates and the central through holes of the side fixing plates, and the left and right parts of the limiting pins 292 are inserted into the corresponding through holes in the corresponding intermediate reinforcing plates.

[0046] Further, the lower part of the turnover positioning plate 291 is inserted into the central through slot formed in the middle part of the bottom plate of the mobile fixing base 29.

[0047] Further, the left and right parts of the bottom plate of the mobile fixing base 29 are formed with a plurality of upper connecting through holes, two pressing plates 293 are below the left and right parts of the bottom plate of the mobile fixing base 29 and below the left and right parts of the top plate of the middle supporting beam 27, a plurality of lower through holes are formed in the pressing plates 293, the screw rods of the fixing bolts are inserted into the corresponding lower through holes and upper connecting through holes, the top ends of the screw rods of the fixing bolts protrude from the top surface of the bottom plate of the mobile fixing base 29 and are inserted with washers and locked nuts, the washers are clamped between the bottom surface of the locked nuts and the top surface of the bottom plate of the mobile fixing base 29, the elastic pressing sleeves are inserted on the screw rods of the fixing bolts, the top surface of the elastic pressing sleeves abuts against the top surface of the bottom plate of the mobile fixing base 29, and the bottom surface abuts against the top surface of the corresponding pressing plate 293, and the left and right parts of the top plate of the middle supporting beam 27 are clamped between the top surface of the corresponding pressing plate 293 and the bottom surface of the bottom plate of the mobile fixing base 29. In use, by tightening the locked nuts, the left and right parts of the top plate of the middle supporting beam 27 are clamped between the top surface of the corresponding pressing plate 293 and the bottom surface of the bottom plate of the mobile fixing base 29, so that the mobile fixing base 29 can be fixed on the middle supporting beam 27 and fixed.

[0048] The principle of movement is as follows: when the lower movable seat 26 needs to be moved forward, the limiting latch 292 on the front side is pulled out, the positioning pin shaft 262 is pulled out, and then all the locking nuts are loosened, and the push rod of the oil cylinder 28 is pushed to move the movable fixed seat 29 forward. At this time, the limit latch 292 on the rear side is blocked, so that the flip positioning plate 291 is flipped counterclockwise and flipped out of the corresponding slot, and then moved forward a position. Then, the flip positioning plate 291 is returned to its original position, and its bottom is inserted into the corresponding slot at this time, and then the oil cylinder 2 is pushed. The push rod 8 retracts. At this time, due to the obstruction of the limit pin 292 on the rear side, the flip positioning plate 291 cannot rotate, so that the movable fixed seat 29 will not move. As the push rod retracts, the lower movable seat 26 is moved forward one position. In this way, the lower movable seat 26 can be moved forward, which makes the oblique support arm 25 change its position and tilt angle, which is very convenient to meet the adjustment needs. It can be moved to the required position. At this time, the bottom of the flip positioning plate 291 is inserted into the corresponding slot, and all the locking nuts are tightened to complete the fixation and realize movement.

[0050] This embodiment allows the hull to move left and right, changing the left and right position of its hammer head 100 to meet the need of changing the rock drilling position, and its adjustment accuracy is high.

[0051] When the hammer head 100 falls naturally to drill rocks, the anti-slip elastic layer 410 of the outer wall of the connecting disk 409 connected to the gear disk 402 can be separated from the inner wall of the annular portion 41 through the compression spring 48. At this time, the reel 40 rotates with the wire rope to realize the free fall operation of the hammer head 100.

[0052] When the wire rope needs to be wound back into place, the push rod of the first push cylinder 405 pushes the adjusting nut 403 to rotate. At this time, the adjusting nut 403 moves a small distance to the left, driving the reel 40 to move a certain distance to the left along the main shaft 401, so that the anti-slip elastic layer 410 of the outer wall of the connecting disk 409 is pressed against the inner wall of the annular portion 41 to achieve connection. The connecting gear disk 402 is driven by the drive motor to drive the reduction gear box to operate, and the reduction gear box drives the connecting gear disk 402 to operate. At this time, it drives the reel 40 to rotate, thereby winding the wire rope to achieve winding.

Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations.
