The retracting mechanism includes a storage frame 9, a reeling component arranged inside the storage frame 9, a pushing component arranged at the bottom of the storage frame 9, and a limiting component arranged at the bottom of the storage frame 9. The buffer mechanism is arranged on the top of the mounting seat 2, one end of the wire rope 19 is connected to the buffer mechanism, and the other end of the wire rope 19 is connected to the retracting mechanism. The buffer mechanism can reel the wire rope 19 after the hammer body 1 hits the rock reef;

[0037] Firstly, the storage frame 9 is installed on the crane, the positioning plate 2201 can be welded on the top of the storage frame 9 through the rib plate 22, and then the positioning plate 2201 is installed on the crane through the screw nut, then the hammer body 1 is lifted through the setting winding and unwinding mechanism, and then the hammer body 1 is adjusted to be horizontal through the setting leveling mechanism, and then the hammer body 1 is lowered through the winding and unwinding mechanism, the rock is broken through the impact of the hammer body 1 falling on the rock, at this time, the buffer mechanism can buffer the steel wire rope 19, prevent the hammer body 1 from being lifted when the steel wire rope 19 is pulled instantaneously, and prevent the steel wire rope 19 from being broken, and when the hammer body 1 is lifted again through the winding steel wire rope 19, the pushing assembly can pull the steel wire rope 19 back and forth, so that the steel wire rope 19 can be uniformly wound on the winding drum 1001, the winding amount of the winding drum 1001 is improved, and the limiting assembly can prevent the hammer body 1 from shaking when the steel wire rope 19 is wound. At the same time, the extrusion assembly can extrude the end of the steel wire rope 19 wound on the winding drum 1001, so that the edge of the wound steel wire rope 19 does not collapse and affects the stable and uniform winding of the steel wire rope 19.

[0038] As shown in Figure 7 and Figure 8 As a preferred embodiment, on the basis of the above mode, further, the leveling mechanism comprises a rotating handle 4 rotatingly arranged on the side wall of the fixed box 3, a winding wheel 5 arranged on the rod wall of the rotating handle 4, a connecting block 101 arranged on the both end side walls of the hammer body 1, and a first pull rope 501 wound on the winding wheel 5, one end of the first pull rope 501 away from the winding wheel 5 is connected with the connecting block 101 through the mounting seat 2.

When the hammer body 1 is tilted, the rotating handle 4 on one side of the top of the mounting base 2 can be rotated to drive the winding wheel 5 to wind the first pull rope 501, at this time, the first pull rope 501 pulls the hammer body 1 to tilt to one side, and thus the rotating handle 4 on the other side of the top of the mounting base 2 can be rotated to drive the hammer body 1 to tilt to the other side, thereby facilitating the adjustment of the angle of the hammer body 1. Finally, the rotating handle 4 is released, at this time, the hammer body 1 pulls the first pull rope 501 to drive the rotating handle 4 and the winding wheel 5 to reverse, but at this time, the pawl 7 clamps the ratchet wheel 6, so that the ratchet wheel 6 cannot be reversed, thereby limiting the rotating handle 4 after the angle of the hammer body 1 is adjusted. When it is necessary to reverse the rotating handle 4 to adjust the angle of the hammer body 1, only the bolt 8 needs to be rotated out, and then the second pull rope 801 is pulled through the bolt 8, so that the pawl 7 is pulled upward to disengage from the ratchet wheel 6, at this time, the ratchet wheel 6 is released, and the rotating handle 4 and the winding wheel 5 can be reversed, so that the hammer body 1 pulls the first pull rope 501 out of the winding wheel 5 and reverses to adjust the angle in the opposite direction. It should be noted that the U-shaped frame 102 is arranged on the top of the hammer body 1, and the rotating block 201 is arranged on the bottom of the mounting base 2 and is rotatably connected with the U-shaped frame 102, so that the hammer body 1 is rotatably connected with the mounting base 2, thereby facilitating the adjustment of the angle of the hammer body 1.

[0045] When the hammer body 1 needs to be lifted, the motor 10 can be started to drive the winding drum 1001 to rotate to wind the steel wire rope 19 to lift the hammer body 1. In this process, the output shaft of the motor 10 drives the winding drum 1001 to rotate, and at the same time drives the lead screw 11 to rotate through the belt 1101. The lead screw 11 drives the moving plate 13 to move at the bottom of the storage frame 9 in cooperation with the sliding rod 12, so as to push the steel wire rope 19 passing through the inside of the first limiting sleeve 1301 to move back and forth at the bottom of the storage frame 9, so as to uniformly wind the steel wire rope 19 on the winding drum 1001, improve the winding amount of the winding drum 1001, and limit the steel wire rope 19 through the fixed rod 14 and the second limiting sleeve 1401, prevent the steel wire rope 19 from being affected by the first limiting sleeve 1301 to drive the hammer body 1 to shake and cause danger.

[0046] As shown in Figure 5 , Figure 6 and Figure 9 , as a preferred embodiment, on the basis of the above mode, further, the winding drum 1001 is provided with a sliding groove 1002, and the winding drum 1001 is further provided with an extrusion mechanism. The extrusion mechanism comprises a support plate 904 arranged on the side wall of the storage frame 9, a first rotating rod 17 rotatably arranged on the top of the support plate 904, a disc 15 arranged on the top of the first rotating rod 17, a pressing sleeve 1003 sleeved outside the winding drum 1001, a sliding plate slidably arranged in the sliding groove 1002 and connected with the pressing sleeve 1003, a pressing rod 1601 arranged on the side wall of the sliding plate and extending outwardly through the end surface of the winding drum 1001, a square frame 16 arranged on the end of the pressing rod 1601 away from the winding drum 1001, and a crank 1501 arranged on the top of the disc 15, the end of the crank 1501 away from the disc 15 is movably connected to the inner wall of the square frame 16;

[0047] The side wall of the support plate 904 is rotatably connected with a second rotating rod 18. The end of the lead screw 11 away from the belt 1101 is connected with a worm 1102. One end of the second rotating rod 18 is connected with a worm wheel 1801 engaged with the worm 1102. The other end of the second rotating rod 18 is connected with a driving bevel gear 1802. The bottom of the first rotating rod 17 is provided with a driven bevel gear 1701 engaged with the driving bevel gear 1802.

[0048] When the screw rod 11 rotates, the second rotating rod 18 provided with the worm wheel 1801 is also driven to rotate through the worm 1102, the second rotating rod 18 drives the first rotating rod 17 provided with the driven bevel gear 1701 to rotate through the driving bevel gear 1802, the first rotating rod 17 drives the disc 15 and the crank 1501 to rotate, the crank 1501 drives the square frame 16 and the pressing rod 1601 to reciprocate, and the pressing rod 1601 drives the pressing sleeve 1003 sleeved outside the winding drum 1001 to reciprocate through the sliding plate, so that the end of the steel wire rope 19 wound on the winding drum 1001 can be extruded, preventing the side end of the steel wire rope 19 wound together from collapsing.

[0049] As shown in Figure 8 As a preferred embodiment, on the basis of the above mode, further, the buffer mechanism comprises support seats 203 symmetrically arranged on the top of the mounting plate 2, a winding shaft 20 rotatably arranged between the two support seats 203, rotating shafts 21 arranged on both side end faces of the winding shaft 20 and extending outward through the support seats 203, and springs 2101 sleeved on the rod walls of the rotating shafts 21, and one end of the steel wire rope 19 away from the winding drum 1001 is connected with the winding shaft 20.

[0050] After the hammer body 1 hits the rock, a large amount of steel wire rope 19 will be in a loose state due to inertia, at which time the spring 2101 drives the rotating shaft 21 and the winding shaft 20 to rotate to wind the loose steel wire rope 19, so that when the hammer body 1 is lifted after hitting the rock, the steel wire rope 19 wound on the winding shaft 20 will be pulled out again and drive the rotating shaft 21 to rotate, at which time the spring 2101 buffers the steel wire rope 19 to prevent the steel wire rope 19 from being broken when the hammer body 1 is lifted.

[0052] The working principle of the present application is as follows: first, install the storage frame 9 on the crane, then lift the hammer body 1 through the set storage mechanism, if the hammer head is clear, rotate the handle 4 on one side of the top of the mounting seat 2, the handle 4 will drive the winding wheel 5 to rotate and wind the first pull rope 501, at this time the first pull rope 501 will pull the hammer body 1 to overturn relative to the mounting seat 2, therefore, according to the need, rotate the handle 4 on both sides of the top of the mounting seat 2, then the hammer body 1 can be turned over to both sides in turn, which is convenient for adjusting the angle of the hammer body 1, and the inclined hammer body 1 is leveled, and finally the handle 4 is released, at this time the hammer body 1 will pull the first pull rope 501 to drive the handle 4 and the winding wheel 5 to reverse, but at this time the pawl 7 will block the ratchet wheel 6, so that the ratchet wheel 6 cannot be reversed, thereby limiting the handle 4 after the angle of the hammer body 1 is adjusted, and when it is necessary to reverse the handle 4 to adjust the angle of the hammer body 1, only need to rotate the bolt 8 to unscrew it, then pull the second pull rope 801 through the bolt 8, then the pawl 7 can be pulled up to disengage from the ratchet wheel 6, at this time the ratchet wheel 6 is released, and the handle 4 and the winding wheel 5 can be reversed, so the hammer body 1 will pull the first pull rope 501 out of the winding wheel 5 and reverse to adjust the angle. Then lower the hammer body 1 through the storage mechanism and hit the rock to break the rock. After the hammer body 1 hits the rock, a large amount of steel wire rope 19 will be in a loose state due to inertia, at this time the spring 2101 will drive the shaft 21 and the reel 20 to rotate to wind the loose steel wire rope 19, so when the hammer body 1 is lifted after hitting the rock, the steel wire rope 19 wound on the reel 20 will be pulled out and the shaft 21 will be rotated, at this time the spring 2101 will buffer the steel wire rope 19 to prevent the steel wire rope 19 from being pulled and broken when the hammer body 1 is lifted. Then start the motor 10 to drive the reel 1001 to rotate to wind the steel wire rope 19 to lift the hammer body 1, in this process, the output shaft of the motor 10 drives the reel 1001 to rotate, and at the same time drives the lead screw 11 to rotate through the belt 1101, the lead screw 11 cooperates with the slide rod 12 to drive the moving plate 13 to move at the bottom of the storage frame 9, thereby pushing the steel wire rope 19 passing through the first limiting sleeve 1301 to move back and forth at the bottom of the storage frame 9, which is convenient for winding the steel wire rope 19 evenly on the reel 1001, improving the winding amount of the reel 1001, and through the setting of the fixed rod 14 and the second limiting sleeve 1401, the steel wire rope 19 can be limited to prevent the steel wire rope 19 from being affected by the first limiting sleeve 1301 to drive the hammer body 1 to shake and cause danger.
