Description
Technical field
The utility model relates to a kind of check mechanism, particularly relates to a kind of rotary drilling rig rotary braking device of getting on the bus.
Background technology
The existing market rotary drilling rig adopts the telescopic drill rod operation basically, and its boring procedure is to carry behind the full a pipeful of soil of brill getting on the ground, turns round about 90 ° and unloads soil, and reversed turning boring to the foramen primum position repeats above action again.In this process because reductor brakes suddenly, moment kinetic energy very big, the moment impact load that acts on speed reducer output shaft is very big, damages reductor easily.In addition in drilling process, because drill bit is run into hard rock or unloaded at every turn that locating hole position, soil back is inaccurate causes inclined to one side brill, drill bit receives very big unbalance loading, produces powerful moment of torsion and passes to reductor, causes the reductor damage.Impulsive torque in revolution and the operation process is to be born by speed reducer output shaft at present, so cause easy damage, the output shaft that increases the Separate Brake rear brake can be shared this moment of torsion, improves the reliability of equipment.
The utility model content
The utility model technical problem to be solved provides the stopping power of a kind of effective increase rig rotary braking ability when creeping into operation, the rotary drilling rig that reduces the damage of the rotary reducer to greatest extent rotary braking device of getting on the bus.
In order to solve the problems of the technologies described above; The rotary drilling rig that the utility model the provides rotary braking device of getting on the bus; Comprise getting on the bus, get off, turning round and support and rotary reducer, at least one cover is installed on described getting on the bus acts on the liquid braking device that described revolution is supported.
Described liquid braking device comprises cylinder body and gear shaft, and the cylinder body of described liquid braking device is installed on described the getting on the bus, and engaged transmission is supported in the gear shaft of described liquid braking device and described revolution.
Shared one tunnel guide's oil circuit fuel feeding of the control oil channel of described liquid braking device and the control oil channel of described rotary reducer.
Described liquid braking device is the normally closed type liquid braking device.
Adopt the rotary drilling rig of the technique scheme rotary braking device of getting on the bus; Owing on getting on the bus, added one or more sets liquid braking devices; Can increase platform rotary braking ability and bear shock loading suffered in the machine drilling process, the output shaft of liquid braking device can be shared this moment of torsion behind the increase liquid braking device, improves the reliability of equipment; Effectively the protection rotary reducer solves the hypodynamic problem of rig Brake Energy.This liquid braking device is the normally closed type structure, and this liquid braking device is different from the structure of hydraulic motor reductor braking part, the not external motor of this brake, and axle does not play the driving rotational operation.The external control oil channel of liquid braking device, the open and close of the piston of control liquid braking device, this oil circuit and rotary reducer oil circuit are worked simultaneously, effectively protect this two elements.
In sum, the required cost of the utility model is lower, uses simply, and the stopping power when effectively increasing rig rotary braking ability and creeping into operation reduces the damage of rotary reducer to greatest extent.

The specific embodiment
The front combines the accompanying drawing and the specific embodiment that the utility model is described further.
Referring to Fig. 1; Get on the bus and 32 support 5 through revolution and be connected with getting off; Guarantee that rig can 360 ° of operations, rotary reducer 1 is installed in gets on the bus on 3, and the output shaft of rotary reducer 1 supports 5 engaged transmission with revolution; The cylinder body of normally closed type liquid braking device 4 is installed in gets on the bus on 3; 5 engaged transmission are supported in the gear shaft of normally closed type liquid braking device 4 and revolution, and rotary reducer 1 passes through shared one tunnel guide's oil circuit fuel feeding of rig with normally closed type liquid braking device 4, and assurance reductor and brake open and close and carry out simultaneously.
Normally closed type liquid braking device 4 is in self-locking and open mode satisfies the rig braking requirement.
Referring to Fig. 1; Get on the bus and 32 support 5 through revolution and be connected with getting off; Guarantee 360 ° of operations of rig ability; Rotary reducer 1 passes through shared one tunnel guide's oil circuit fuel feeding of rig with normally closed type liquid braking device 4, and assurance rotary reducer 1 opens and closes with normally closed type liquid braking device 4 and carries out simultaneously, follows these steps to executable operations:
1, to rotary reducer 1 and 4 effects of normally closed type liquid braking device, the gear shaft of the output shaft of rotary reducer 1 and normally closed type liquid braking device 4 is not static, makes 3 pinnings of getting on the bus for rotary drilling rig drilling process, control oil channel;
2, carry to ground when above when the drilling bucket that bores full soil; The unlatching revolution button of getting on the bus, oil circuit fuel feeding are simultaneously given rotary reducer 1 and normally closed type liquid braking device 4, and oil pressure promotes rotary reducer 1 and 4 motions of normally closed type liquid braking device; Make it not play braking action to gear shaft; This moment, the motor of rotary reducer 1 turned round, and then the driving rotational support 5 and 3 revolutions of getting on the bus, and turned round the gear shaft and the tooth engagement revolution of turning round support 5 of Closed Hydraulic brake 4 often;
3, when being turned back to when needing the position, close the revolution button, the control oil channel oil pressure cuts off, and the motor of rotary reducer 1 does not turn round, and rotary reducer 1 produces braking with normally closed type liquid braking device 4 simultaneously, and then makes 3 brakings of getting on the bus.
4, unsnatch soil after, operate drilling rod and get back to the foramen primum position, only need step 2 above the repetition, just the direction of rotation of CD-ROM drive motor is opposite.
This novel rotation arrestment mechanism advantage is described further.
With reference to Fig. 2; Rig does not in the market have normally closed type liquid braking device 4, and braking is all controlled rotary reducer 1 separately by one tunnel guide's oil circuit and accomplished, with reference to Fig. 3; The impulsive torque M that produces in the rotary drilling rig work is born by rotary reducer 1 fully, and the damage of reductor 1 is very risky.
With reference to Fig. 4, the work of novel rotation arrestment mechanism, the impulsive torque M that rotary drilling rig produces is born by rotary reducer 1 and normally closed type liquid braking device 4, and the moment of torsion that rotary reducer 1 bears is less than M, and reductor 1 damages risk to be reduced greatly.
