The beneficial effect of the utility model is: reaming bit quick crushing operation under the impact energy effect of hydraulic impactor creeps into, and Compressed Gas or mud are discharged the boring mud that reaming bit produces through first passage, second channel, slag releasing channel and slagging channel in drilling process.Like this; The impact energy of reaming bit is provided by hydraulic impactor, and the required energy of deslagging is replaced by Compressed Gas or mud, needs the single energy of consumption less; Can effectively reduce the energy consumption of respective air compressor or mud plant and hydraulic power unit like this, reach energy-saving effect.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The embodiment of a kind of worker's drilling apparatus is as shown in Figure 1: comprise revolution sleeve pipe 3 and the drilling mechanism that is arranged in the revolution sleeve pipe 3 by corresponding drive power source.Drilling mechanism comprises having reaming bit 4 that creeps into work plane 11 and the hydraulic impacter with piston 1 and cylinder body 2; (the Wedge-type reaming bit is a prior art to reaming bit 4 for the reaming bit of Wedge-type reducing; Its concrete structure no longer details); Be provided with a plurality of brill teeth 6 of changing can selected according to difference construction stratum on the work plane 11 creeping into; The lower end of cylinder body 2 is connected with syndeton 9, reaming bit 4 with syndeton 9 sealed rotational assemblings in and be in transmission connection with the impact energy output of piston 1, the bearing of trend of the pivot center of reaming bit 4 is consistent with the vibration-direction of piston.The inserting syndeton that the lower end of revolution sleeve pipe 3 connects through the convex-concave inserting is ended spinning and is joined.The periphery of cylinder body 2 is connected with deslagging structure 13; Be provided with slagging channel 8 between the inwall of the outer wall of deslagging structure 13 and revolution sleeve pipe 3; Be provided with in the deslagging structure 13 and be used for the first passage 10 that is communicated with corresponding source of the gas (or mud plant); Be provided with the second channel 7 that is communicated with first passage 10 and creeps into work plane 11 in the reaming bit 4, second channel 7 has a plurality of.Also be provided with in the reaming bit 4 and be communicated with the slag releasing channel 5 that creeps into work plane 11 and slagging channel 8.12 expressions realize that reaming bit 4 changes the voussoir 12 of diameter among the figure.
During use; Revolution sleeve pipe 3 all can rely on corresponding pile frame oscilaltion with drilling mechanism, and revolution sleeve pipe 3 is by corresponding drive power source, and revolution sleeve pipe 3 is just changeing; The voussoir 12 of reaming bit 4 stretches out; Reaming bit 4 creeps into operation under the acting in conjunction of hydraulic impacter and revolution sleeve pipe 3, compressed air (or mud) is discharged the boring mud that reaming bit 4 produces through slagging channel 8 in drilling process, is reaming bit 4 coolings simultaneously.After reaming bit 4 creeps into desired depth, counter-rotating revolution sleeve pipe 3, voussoir 12 withdrawals are come out drilling mechanism by lifting in the revolution sleeve pipe 3.So that subsequent processing is laid the reinforcing cage concrete perfusion.Under the acting in conjunction through revolution sleeve pipe 3 and hydraulic impacter; The drilling efficiency of this worker's drilling apparatus is higher; And the compressed air (or mud) that hemisphere gas compressor station (or mud plant) provides only is used for deslagging acting; Pressure requirement to compressed air (or mud) is lower, has saved the energy.Through compressed air (or mud) boring mud of pore-forming bottom is all discharged simultaneously, realized not having sediment at the bottom of the hole, percussion drilling has the end load that reinforcement effect has improved stake at the bottom of to the hole.
In other embodiment of the utility model: syndeton can also be connected with the cylinder body welding or pass through bolt, nut body releasable connection; Reaming bit can also adopt the reaming bit (the eccentric type reaming bit is a prior art, and its concrete structure no longer details) of eccentric type reducing, and this moment, slag releasing channel can be arranged between reaming bit and the revolution sleeve pipe; And the number of second channel can also be one, two, three or more, also can not intersect between each second channel to communicate and independent respectively the setting; Boring tooth also can change according to the construction needs; The deslagging structure can also be made up of the defeated slurry of the air inlet that is sheathed on cylinder body periphery sleeve pipe, and this moment, first passage was arranged between air inlet defeated slurry internal surface of sleeve pipe and the outer wall of cylinder block; Certainly the deslagging structure can also constitute by being arranged at the peripheral air inlet grout pipe line of cylinder body, and this moment, first passage was made up of the internal channel of said air inlet grout pipe line; Certainly the revolution sleeve pipe can also be to can't help the active sleeve pipe of corresponding drive power source, this moment reaming bit only receive the impact force of hydraulic impacter creep into or in case of necessity drilling mechanism do back and forth and slowly run.
