Description
Technical field
The utility model relates to a kind of rig, particularly relates to a kind of engine on frame and is in transmission connection by clutch and speed changer, the rig that speed changer is in transmission connection by transfer case and gyrator and hoist engine.
Background technology
In recent years, country looks for the miner to attach great importance to geology, and the input of geological prospecting continues to increase, and the geological drilling task significantly increases.Under these circumstances, the professional contingent that is engaged in core drilling needs to increase rig because task strengthens, the part past has regained ground by approach such as bids and has surveyed the core drilling task from the change one's profession troop of engineering exploration, construction of geological prospecting, also is badly in need of buying new rig.Therefore, drilling depth is that supply falls short of demand for 1000～1500 meters core-drill(ing) machine.A kind of vertical shaft type core-drill(ing) machine is arranged at present, drilling depth is 1000～1500m, its structure is to be provided with engine and clutch on frame, gearbox and transfer case, hoist engine and gyrator, engine adopts shaft coupling to be connected with clutch with gearbox, and spacing is bigger, gearbox adopts universal joint to be connected with transfer case, its spacing is bigger, causes complete machine length long, reaches about 3.5 meters; There is following defective in the transfer case transmission: travelling gear all adopts straight-tooth, and meshing performance is relatively poor, and overlap coefficient is little, and intensity is low; Go gyrator to adopt the direct engage a gear of straight-tooth, gear shift inconvenience, shifting shock are big, cause gear to damage in early days, and easily out of supply, noise is big; Go hoist engine to adopt the gear shift of clutch internal gear, do not engage the gear ring form, cause travelling gear to damage easily but adopt to add.
The utility model content
It is better that technical problem to be solved in the utility model provides a kind of transfer case travelling gear meshing performance, and overlap coefficient is big, gear shift is convenient, shifting shock is little, be difficult for rig out of supply, that noise is little.
In order to realize above-mentioned technical goal, the rig that the utility model provides comprises frame, rack-mounted engine is in transmission connection by clutch and gearbox, gearbox is in transmission connection by transfer case and gyrator and hoist engine, the power shaft helical gear of described transfer case is fixed on the power shaft, is enclosed within on the axle of passing a bridge with the gap bridge helical teeth bye of described power shaft helical gear engaged transmission; Helical gear and quick helical teeth bye are enclosed within on the output shaft at a slow speed, the gap bridge helical gear respectively with described helical gear at a slow speed and quick helical gear engaged transmission, described helical gear at a slow speed both sides are equipped with first respectively and are engaged the gear ring and the second joint gear ring, first clutch collar that is provided with shift fork can engage gear ring as required with first and go hoist engine shaft gear engaged transmission simultaneously, described quick helical gear one side is provided with the 3rd and engages gear ring, the internal tooth of tooth hub is meshed with the external tooth of output shaft, the little circular-arc bevel gear and the described gyrator of described output shaft are in transmission connection, and the external tooth that second clutch collar that is provided with shift fork can engage gear ring and tooth hub as required with second is engaged transmission or engages the external tooth while engaged transmission of gear ring and tooth hub with the 3rd simultaneously.
Transfer case is another vitals of rig transmission system, because it is in the rear end of driving-chain, rotating speed is low, moment of torsion is big.And the helical gear transmission has registration big, and the stable transmission characteristics are suitable for high speed, heavy load transmission.The utility model adopts cylindrical helical gear drive, has improved supporting capacity, has improved operating characteristics.The helical gear rotation direction of appropriate design makes two helical gear axial force directions on the carrier gear on the axle of passing a bridge opposite, or the right gear simultaneously and two helical gears when meshing two axial forces opposite, most of axial force is cancelled out each other.The helical gear rotation direction of appropriate design makes two helical gears on the output shaft, and promptly helical gear and quick helical gear axial force are opposite with the axial force direction of little circular-arc bevel gear at a slow speed, and most of axial force is cancelled out each other.
Transfer case structure and operating principle are as follows: the internal tooth of first clutch collar and second clutch collar and the external tooth of tooth hub or remove the hoist engine shaft gear and first engage that gear ring, second engages gear ring, the 3rd profile of tooth and the number of teeth that engages between the gear ring is all identical.When desire is hung a certain shelves, stir first clutch collar or second clutch collar and make it with the tooth hub or remove the hoist engine shaft gear and first engages gear ring or second and engage gear ring or the 3rd and engage gear ring and mesh simultaneously, promptly extension these shelves.
Engage in the shell type gearshift at above-mentioned transfer case, have only clutch collar, joint gear ring and tooth hub to be impacted during gear shift, helical gear can not impacted.Because soldered tooth is short, the shift fork amount of movement is little during gear shift, so operation is light, and the area that gear shift withstands shocks increases, impact when making gear shift to reduce, the engaging element clutch collar, engage gear ring and tooth hub life-span than in the past generally the gear shift spur gear of employing prolong greatly.And the three all is general auto parts machinery, and is cheap, and it is convenient to buy.
Described gearbox is an automotive transmission.Gearbox and clutch are the important component parts of rig transmission system.This type speed changer has 6 drive shifts, a reverse gear, two to six grades often mesh for helical gear, synchronizer shift, reverse gear is a spur gear, takes the clutch collar gear shift, and is easy to operate.
Described engine is in transmission connection by diaphragm type spring clutch and gearbox.This diaphragm type spring clutch has nonlinear loaded-deformation characteristic, during clutch driven plate friction material wear-out life, can keep constant operating pressure, thereby make clutch can keep stable torque capacity, transmit maximum engine torque reliably.In order to alleviate driller's labour intensity, clutch adopts hydraulic operating mechanism.Simultaneously, the consistent lubricant pipe that utilizes hydraulic operating mechanism is advanced to operating grip near the aperture, operated clutch when having made things convenient for driller to carry out the aperture operation.In order to guarantee the application life of clutch, when having only operation, just clutch separates, the clutch of loosing one's grip promptly is in closure state, has avoided clutch release bearing to damage in early days.
The power shaft of described transfer case is in transmission connection by internal tooth form yielding coupling and described speed changer.The internal tooth form yielding coupling allow bigger axially, radially and angular displacement, have simple in structure, easy to maintenance, easy disassembling, noise is low, efficient is high, the advantage of long service life.And transfer case is in transmission connection by internal tooth form yielding coupling and speed changer, has shortened the length of complete machine greatly, and complete machine is shortened to about 2.5 meters.In addition, rig is constructed in the open air, is equipped with many that diesel engine is used as power, and vibrates greatlyyer, has installed automobile-used cushion pad between engine and borer frame additional.
In sum, the utility model is that a kind of transfer case travelling gear meshing performance is better, overlap coefficient is big, gear shift is convenient, shifting shock is little, it is out of supply to be difficult for, complete machine vibrations are little, noise is little, technical data is reasonable, performance is complete, reliable operation, efficiency of construction height, operation easily and the rig of complete machine contraction in length.
