Description
Technical field
The utility model relates to rig field, is specifically related to a kind of water drilling rig unit head.
Background technology
Drilling tool is when bore operation, and owing to adopting motor to drive, its moment of torsion is relatively little, when hardpan uses, there is the problem of boring difficulty.The speed change system of the use of traditional rig mostly is gear reduction unit, and complex structure is bulky, the machine made oversize, and noise is large simultaneously, often needs lubrication, maintenance trouble.In drilling process, dismounting and install the many people of process need of drilling rod and coordinate up and down, both wastes of manpower, is inconvenient to operate, and produces again many unsafe factors, also directly affects the efficiency of drilling well.
Summary of the invention
The utility model is for solving the problem, and provide a kind of compact conformation, gearratio is high, the water drilling rig unit head of drilling rod for convenience detach.
The utility model realizes by the following technical solutions, a kind of water drilling rig unit head, comprise housing, by the motor that flange is connected with housing rear end, be arranged on the main shaft that enclosure interior is be arranged in parallel by transmission device and motor shaft, the Cycloidal pin-wheel drive device connecting motor and main shaft is provided with between flange and housing, aeration type structure centered by described main shaft, be flexibly connected with front-end of spindle and be connected with fixed cover with housing into rotation, fixed cover front end is flexibly connected drilling rod connecting dish and rod disassembling device successively, drilling rod connecting disk center is with the hickey coordinated with drilling rod, rod disassembling device is rectangular structure, its side is with the through hole matched with drilling rod stopper slot, central airway one end of described main shaft is connected with air feed equipment by the air inlet port of hull outside, and the other end is communicated with drilling rod by the hickey on fixed cover.
For making connection reliable, described fixed cover and main shaft connected mode are spline joint.
Fixing reliable for making, be provided with fixing nut between described fixed cover and main shaft.
For making inner and extraneous sealing, the junction between described fixed cover and housing is provided with seal cover.
For alleviating vibrations and noise, described drilling rod connecting dish and fixed cover junction are provided with beam.
Usefulness of the present utility model is, adopt Cycloidal pin-wheel drive design to make compact integral structure, gearratio increases greatly, and power-lift is high, and retardation efficiency promotes, and the volume of complete machine is reduced, weight saving, and noise reduces to increase application life; The setting of rod disassembling device makes the dismounting of drilling rod and easier for installation, quick, substantially increases drilling efficiency, shortens drilling time, alleviate the burden of operating personnel, ensure safety.
Accompanying drawing explanation

1. motors, 2. flange in figure, 3. Cycloidal pin-wheel drive device, 31. Cycloidal Wheel, 4. housing, 41. air inlet ports, 42. main shafts, 5. seal cover, 6. fixed cover, 61. nuts, 62. beams, 7. drilling rod connecting dish, 71. hickeys, 8. rod disassembling device, 81. through holes.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of water drilling rig unit head, comprise housing 4, motor 1 is connected with housing 4 rear end by flange 2, housing 4 inside is provided with main shaft 42, main shaft 42 is connected with motor by transmission device, improvements are to be provided with the Cycloidal pin-wheel drive device 3 connecting motor 1 and main shaft 42 between flange 2 and housing 4, increasing speed reducing ratio, is that whole reducing gear is compacter, reduces volume; Aeration type structure centered by main shaft 42, main shaft 42 front end is provided with spline structure, be flexibly connected with main shaft 42 and be rotatably connected to fixed cover 6 with housing 4, fixed cover 6 front end is flexibly connected drilling rod connecting dish 7 and rod disassembling device 8 successively, drilling rod connecting dish 7 center is with the hickey 71 coordinated with drilling rod, rod disassembling device 8 is rectangular structure, and its side is with the through hole 81 matched with drilling rod stopper slot; Central airway one end of main shaft 42 is connected with air feed equipment by the air inlet port 41 outside housing 4, and the other end is communicated with drilling rod by the hickey 71 on fixed cover 6.
In order to better fixed main shaft, between fixed cover 6 and main shaft 42, be provided with fixing nut 61.In order to make parts better be sealed, the junction between fixed cover 6 and housing 4 is provided with seal cover 5.The impact of drilling rod and main shaft 42 during in order to alleviate vibrations, drilling rod connecting dish 7 and fixed cover 6 junction are provided with beam 62.
When dismounting first drilling rod, spacing spanner is only needed to insert in the through hole 81 of rod disassembling device 8, the limiting section of drilling rod just clamps with spacing spanner, the drilling rod be arranged on unit head is just fixed and rotates together with main shaft, after utilizing the fixing lower kelly bar of spanner, reverse starting motor 1 just can realize the separation of upper and lower drilling rod, the drilling rod of top is just fixed on rod disassembling device 8, at this moment the bottom of kelly bar is fixed, extract the spacing spanner of through hole 81 out, upper kelly bar just can unload by reverse starting motor 1 completely again.When continuing the drilling rod unloading below, lower kelly bar is aimed at rod disassembling device 8 and is fallen by unit head, insert spacing spanner when the limiting section of drilling rod appears in through hole 81, at this moment promote unit head and just lower kelly bar can be mentioned, fix reverse starting motor below this drilling rod and just can complete the unloading of this drilling rod.
The utility model compact conformation, gearratio is large, and power is stronger, and application life increases, and the noise that operates steadily is little; Dismounting drilling rod is convenient and time-saving, substantially increases the take-down time of drilling rod, and again because also must install drilling rod before installing drilling rod, therefore also indirectly improve the efficiency of installing drilling rod, make whole drilling time shorter, efficiency is higher.
