Because the protection baffle 4 is always pushed out outwards when the protection baffle is used, the actual position of the drill rod 3 is not easy to observe when the protection baffle is used, accurate striking is not easy to perform on a hard layer, referring to fig. 3, 4 and 6, in the embodiment, the sliding mounting frame 17 is movably mounted at the top end of the inside of the liquid distribution box 8, the sliding mounting frame 17 slides in the direction perpendicular to the central line of the drill rod 3, meanwhile, the pressure regulating magnet 14 is fixedly mounted in the sliding mounting frame 17, the pressure regulating magnet 14 is an L-shaped strong magnet, a through magnetic track 801 for enabling one end of the pressure regulating magnet 14 to be opposite to the liquid distribution cavity 800 is formed in the liquid distribution box 8, the driving magnet 13 positioned below the through magnetic track 801 is fixedly mounted at the top end of the protection baffle 4, the driving magnet 13 is attracted with the magnetism of the pressure regulating magnet 14, the two pressure regulating magnets 14 are symmetrically arranged through the central line of the drill rod 3, and the opposite magnetic surfaces of the two pressure regulating magnets 14 are in a magnetic repulsion relation.
In the use process, referring to fig. 3 and 4, when the drill rod 3 is lifted, the top of the anti-falling groove is pressed on the anti-falling stop lever 6 by the gravity of the drill rod 3, at this time, the magnetic surfaces of the anti-falling groove are opposite between the pressure regulating magnets 14, the two pressure regulating magnets 14 are far away from each other until the sliding mounting frame 17 is attached to the liquid separating box 8, at this time, the magnetic attraction between the pressure regulating magnets 14 and the driving magnets 13 attracts the protective stop tube 4 upwards, so that the medium in the liquid separating cavity 800 is conveyed to the liquid exchanging hole 9, the medium pressure added into the oil storage cavity 200 overcomes the elasticity of the protective spring 10, so that the medium with pressure can push the pressurizing frame 16 to move upwards in the process of moving the protective stop tube 4, the lifting of the slow-pressure stop plate 7 is ensured, and after the protective stop tube 4 is completely retracted into the liquid separating box 8, the drill rod 3 is exposed and is easy to position, and at this time, the lifting of the slow-pressure stop plate 7 can be maintained by the elasticity of the protective spring 10.
When a hard layer is required to be hit, the drill rod 3 is pressed on the hard layer at first, the bottom of the anti-falling groove is propped against the anti-falling stop lever 6, so that when the drill rod 3 is hit by the hammer rod 201, a certain movable space is reserved, the anti-falling stop lever 6 is prevented from directly bearing the hitting strength of the hammer rod 201, at the moment, the upward movement of the drill rod 3 shields the two pressure regulating magnets 14, one end of the pressure regulating magnet 14 can attract the drill rod 3, so that the pressure regulating magnet 14 moves towards the drill rod 3, the pressure regulating magnet 14 is separated from the through magnetic track 801, the drill rod 3 is already arranged on the hard layer at the moment, the driving magnet 13 cannot provide lifting of the protection stop tube 4, under the elastic action of the protection spring 10, mediums in the oil storage cavity 200 are extruded into the liquid separation cavity 800, the protection stop tube 4 moves downwards, and the protection stop tube 4 moves downwards due to the fact that the mediums in the liquid separation cavity 800 are increased, therefore the drill rod 3 can hit in the vertical direction, the situation can be broken under the condition of a certain angle, and then the drill rod 3 can be broken, and then the drill rod 3 can be prevented from being scattered outside the drill rod 3 after the impact, and the impact phenomenon can be prevented from being scattered on the drill rod 3. After the work is finished, the top of the anti-falling groove on the drill rod 3 is pressed on the anti-falling stop lever 6 as described above through the lifting of the drill rod 3, and then the lifting of the protection stop tube 4 is realized, and the drill rod 3 is exposed.
In the second embodiment, when the drill rod 3 is driven to move downwards, the downward moving drill rod 3 drives the anti-drop slot to move downwards synchronously, so that the magnetic surfaces of the pressure regulating magnet 14 are opposite, when the drill rod 3 moves downwards and the pressurizing frame 16 does not block the liquid changing hole 9, the pressure regulating magnet 14 is forced to move above the through magnetic track 801, so that the protection baffle tube 4 moves upwards, therefore, in the embodiment, the magnetic baffle plate 172 between the pressure regulating magnets 14 is movably sleeved in the sliding mounting frame 17, the bottom of the magnetic baffle plate 172 and the inside of the sliding mounting frame 17 are provided with the detection cavity 170, the magnetic baffle tension spring 15 is arranged in the detection cavity 170, the top of the magnetic baffle tension spring 15 is fixedly connected with the magnetic baffle plate 172, the bottom of the magnetic baffle tension spring 15 is fixedly connected with the sliding mounting frame 17, the magnetic surfaces between the pressure regulating magnet 14 are not opposite through the shielding of the magnetic baffle plate 172, the magnetic repulsion phenomenon is not generated, the magnetic baffle plate 172 is pulled according to the magnetic baffle tension spring 15, the magnetic shielding plate 172 is retracted into the detection cavity 170, so that the magnetic surface between the pressure regulating magnets 14 is not affected, a detection oil duct 171 for communicating the detection cavity 170 with the through magnetic track 801 is arranged at the bottom of the sliding mounting frame 17, the medium in the detection cavity 170 and the through magnetic track 801 is communicated, a guide groove 802 positioned at one side of the sliding mounting frame 17 is arranged in the liquid separation box 8, referring to fig. 6, a cylindrical rod is arranged on the side wall of the magnetic shielding plate 172 in a push-out manner, and is arranged in the guide groove 802, referring to fig. 4 and 8, the guide groove 802 is a rectangular groove with round corners at two ends, and the upper part of the guide groove 802 is an inclined surface, when the sliding mounting frame 17 moves to the rightmost side of the guide groove 802, referring to fig. 4, the magnetic shielding plate 172 is limited by the upper part of the guide groove 802, the magnetic shielding plate 172 is pressed into the detection cavity 170, the magnetic surfaces of the two pressure regulating magnets 14 can be opposite, when the bottom of the anti-drop slot on the drill rod 3 is propped against the anti-drop stop lever 6, the magnetic force of the pressure regulating magnet 14 to the drill rod 3 attracts the pressure regulating magnet 14 to move away from the through magnetic track 801, and as the medium pressure in the liquid distribution cavity 800 is elastically extruded by the protection spring 10, the medium in the through magnetic track 801 has the same pressure, so that the detection cavity 170 can push the magnetic blocking plate 172 upwards and overcome the tensile force of the magnetic blocking tension spring 15, the upward magnetic blocking plate 172 moves on the upper part of the guide slot 802 through pushing, the pressure regulating magnet 14 moves far away from the guide slot 802, after that, when the drill rod 3 and the pressure regulating baffle 7 are impacted downwards by the hammer rod 201, the pressurizing frame 16 downwards extrudes the liquid distribution cavity 800, so that the medium pressure in the through magnetic track 801 increases, and the excessive medium can flow back into the oil storage cavity 200 from the liquid exchange hole 9, the protection spring 10 is further compressed, and meanwhile, the pressure increase in the detection cavity 170 can force the magnetic blocking plate 172 to be always in an ejection state, so that the pressure regulating magnet 14 is always far away from the through magnetic track 801, namely, the magnetic blocking plate 172 is kept away from the guide slot 802, the magnetic blocking plate 3 is prevented from being lifted up by the guide rod 3, and the magnetic blocking rod is prevented from being lifted down by the guide rod 4, and the magnetic blocking rod 3 is prevented from being lifted down by the guide rod 3, and the magnetic blocking rod is prevented from being lifted down by the guide rod 3, and the magnetic rod 3 is not pressed down by the magnetic blocking rod 3, and the magnetic blocking rod 3 is prevented from being lifted down from the magnetic rod 3:
if the pressurizing frame 16 plugs the liquid exchange hole 9, the protecting baffle tube 4 is extended outwards under the gravity of the protecting baffle tube, the pressure in the liquid separation cavity 800 is reduced, the magnetic blocking tension spring 15 pulls the magnetic blocking plate 172 back to the detection cavity 170, and the medium in the detection cavity 170 flows back to the liquid separation cavity 800 from the magnetic through track 801 through the detection oil duct 171.
If the pressurizing rack 16 does not seal the liquid exchange hole 9, all the extending protecting springs 10 can input medium in the oil storage cavity 200 to the liquid distribution cavity 800 to the greatest extent, but the protecting baffle tube 4 still extends outwards for a certain distance under the self gravity, so that the magnetic blocking tension spring 15 still can pull back the magnetic blocking plate 172, the magnetic blocking plate 172 is retracted into the detecting cavity 170, and finally, the bottom of the pressure regulating magnet 14 can be moved to the position above the through magnetic track 801 through magnetic repulsion between the pressure regulating magnet 14, so that the magnetic attraction between the pressure regulating magnet 14 and the driving magnet 13 pulls back the protecting baffle tube 4.
In combination with practical use, an extension spring may be appropriately added into the liquid separation cavity 800, so that the protection baffle tube 4 is ejected out by the extension spring under a certain elevation angle, and the extension of the protection baffle tube 4 can still be maintained.
Since the current method needs to press on the ground by means of the protection blocking tube 4 when the hammer rod 201 is in idle striking, the hammer rod 201 can be directly struck on the drill rod 3, the final force is transferred to the anti-drop blocking rod 6, in order to reduce the impact load, referring to fig. 3, in the current embodiment, the decompression blocking rod 12 is added, the decompression blocking rod 12 is fixedly installed through the side part of the pressure regulating magnet 14, the decompression blocking rod 12 penetrates into the inner cavity of the hammer 2 from the sliding mounting frame 17 and the guide groove 802, at this time, the decompression blocking rod 12 is positioned at one side of the slow pressing leg 18, and in combination with fig. 7, the inner side of the slow pressing leg 18 is provided with an inclined plane which is opposite to the decompression blocking rod 12, so that when the device is in idle striking, the downward moving drill rod 3 is opposite to the magnetic surface between the pressure regulating magnets 14 through the anti-drop groove, and the inclined plane of the slow pressing leg 18 pushes the decompression blocking rod 12, so that the pressure regulating magnet 14 is far away from the through the track 801, since the bottom of the protection baffle tube 4 is not resistant at this moment, the protection baffle tube 4 can extend completely, the force of striking the pressure reducing baffle 7 can also make the pressurizing rack 16 squeeze the liquid separating cavity 800, the medium pressure in the liquid separating cavity 800 can not increase due to the continuous extension of the protection baffle tube 4, the medium pressure in the detecting cavity 170 can not increase, the tension of the magnetism reducing tension spring 15 is received, the magnetism blocking plate 172 withdraws into the detecting cavity 170, the magnetism repulsion phenomenon exists between the pressure regulating magnets 14 all the time, the pressure reducing baffle rod 12 can be continuously pressed when the pressure reducing legs 18 continuously move downwards, the pressure reducing baffle rod 12 is forced to drive the two pressure regulating magnets 14 to approach, at this moment, the maximum magnetic surfaces between the two pressure regulating magnets 14 are opposite, the repulsive force is maximum, and the two pressure regulating magnets 14 approach each other, the magnetism repulsion between the two pressure regulating magnets is further increased, the limiting strength to the pressure reducing legs 18 is increased through gradually increased magnetic repulsive force, until the kinetic energy of the downward impact in the hammer stem 201 is absorbed by the pressure relief damper 7, that is, the hammer strength of the hammer stem 201 in the idle state is absorbed by the magnetic buffer.
