Description
Technical field
The utility model belongs to the driling rig field, and the deep hole rock-core borer that is specifically related to a kind of fluid motor-driven send the brill winch.
Background technology
Rock-core borer is the machinery of a kind of solid mineral deposit exploration and geological sciences probing collect specimen; Along with the demand of China's economic development to mineral resources sharply strengthens; Geologic hazard takes place frequently and need find the rule of moving towards of earth formation deep fault zone; Deep hole rig with regard to a kind of deep hole of an urgent demand (boring dark ability more than 3000 meters), small-bore (bore diameter is not more than 95mm); This kind rig is compared the needs that power match is fit to geology core exploration drillng technology more with oil-well rig, also absorbed the form of creeping into that rotating disk revolution or top refoulement commentaries on classics, winch send brill.
Existing all-hydraulic core drill winch does not generally possess the function of sending brill, only possesses the function that puts drilling tool, and particularly middle shallow bore hole rig all adopts unit head revolution hydraulic ram to feed the mode of sending brill.Petroleum drilling machine winch generally all possesses the brill of sending function, and most of winch all adopts direct motor drive, and alternating-current variable frequency motor or disk type brake send the form of brill.Yet petroleum drilling machine winch can not be brought and directly be used for the core geological rig, and following reason is arranged:
1. the drilling tool of oil-well rig use is generally all than the weight of core geological rig, and bore diameter is relatively also big, and what the power of the boring winch of same drilling depth will be big relatively is many, causes waste.
2. send that to bore stability not enough, it is also not enough to send the accuracy rate of brill to be used for the core geological rig.
3. employing direct motor drive must increase by a cover AC frequency conversion control system, has changed the structure of winch simultaneously, and volume is big, complex structure, and cost is higher.
4. oil-well rig seldom has the hydraulically powered brill winch that send, and electric motor driven winch is used for hydraulically powered core geological rig, and existing direct motor drive has hydraulic-driven again, is not easy to plant maintenance, operation is complicated, and cause power waste.
The utility model content
The deep hole rock-core borer that the purpose of the utility model provides a kind of fluid motor-driven send the brill winch, the purpose that to solve the above-mentioned technical matters that exists in the background technology, reach simple in structure, be easy to control, control accuracy is high, cost is low, function is complete.
The utility model adopts following technical scheme: the utility model comprises capstan drum, planetary reduction gear, hydraulic efficiency pressure system, variable-dis-placement motor, front brake, rear brake; Planetary reduction gear is built in the capstan drum; Variable-dis-placement motor passes to planetary reduction gear with moment of torsion through castellated shaft, and winch front brake and rear brake are separately fixed on the winch frame, and retarder has former and later two axles; Front brake and rear brake are braked front axle and rear axle respectively, and variable-dis-placement motor links to each other with winch through retarder; Hydraulic efficiency pressure system links to each other with variable-dis-placement motor, front brake and rear brake respectively; Front brake is a dry type spring locking friction disk type drg, opens front brake by hydraulic ram, and rear brake is a wet type spring locking friction disk type drg, opens rear brake by hydraulic ram.
Hydraulic efficiency pressure system is circumscribed with the rig controller of its operation of may command, and the rig controller is circumscribed with the measurement bit weight sensor; Variable-dis-placement motor is circumscribed with tachogen, and the tachogen other end and rig controller join.
Wherein, the rig controller is computing machine, micro controller system or Programmable Logic Controller.
The deep hole rock-core borer that the utility model provides send brill winch advantage to be:
1. be applicable to deep hole core geological rig.Fluid motor-driven, speed adjustable range is wide.Send the hydraulic oil source that bores control to take from drilling rig hydraulic system, compare with the direct motor drive winch, need not frequency-variable controller, simple in structure, cost is low.
2. send and bore the precision height.Drill feeding facility is simple, send the brill mode easy, and control method is various.Can realize unpowered transfer controlled free off the hook, energy-conserving and environment-protective.
3. volume is little and simple in structure.The hydraulic-driven volume is little, flexible arrangement.Retarder is built in the capstan drum, further saves the space.In case adopt to meet in the antero posterior axis dual brake hole to block and to realize emergent the lifting.
