The V belt groove 99 exported on vee-pulley 90 is rotated centered by rotating disk pivot pin 188 by triangular driving band 502 driving pulley rotating disk 179, and circumgyration campaign done by related slide block pivot pin 177 then; While its center through hole 508 on dish bar slide block 159 makes circumference rotation-sliding with pivot pin step section 772 cylindrical on slide block pivot pin 177, force on the slide block elongated slot 157 of two planes up and down on dish bar slide block 159 on drilling well fork 153 and do sliding motion, drive drilling well fork 153 to make swinging motion centered by fork pivot pin 503, finally realize the large rope 152 of drilling well and move up and down and obtain seabed crude oil.

Four, the utility model has following substantive distinguishing features and progress:

(1), job platform 110 has four platforms hinge 144 to be connected with welding spring buffer 145 one end, welding spring buffer 145 other end is connected with fixed feet 146, and presents 45 degree of angles between described welding spring buffer 145 and described job platform 110 plane and arrange.

Under sea beat, when spring buffer 145 subjects tensile load in welding, by compression, and the second bidirectional spring 276 is stretched the first bidirectional spring 256 in welding spring buffer 145;

Under sea beat, when welding spring buffer 145 subjects pressure load, then the first bidirectional spring 256 is stretched, and the second bidirectional spring 276 by compression.

No matter be under pressure or under tension impact, welding spring buffer 145 can both play the effect of buffering, guarantees that job platform 110 can resist the sea beat from any orientation.

(2), have employed connection jaws seat 75 in squirrel-cage flame proof vee-pulley motor 180 mouth seat endoporus 79 is suitable for reading has mouth seat flange 78, connection jaws seat 75 has endoporus shoulder block 22 bottom mouth seat endoporus 79, and endoporus shoulder block 22 center has between wiring through hole 23 and mouth seat endoporus 79 and has axiality; Gland flange 17 outer rim has gland through hole 37 corresponding with the screw on mouth seat flange 78, the inner face of gland flange 17 having between gland boss 39 and mouth seat endoporus 79 is matched in clearance; Gland flange 17 center has gland inner bolt hole 38 to match with the inner external screw thread of pin interfaces 50; The first pad 19, closed hole circle 67 and the second pad 18 is had successively between endoporus shoulder block 22 and gland boss 39, above-mentioned outlet structure is applicable to the outlet of explosion-proof motor, have safe and reliable to operation, Installation and Debugging convenient, save air compressor machine inner space, winding displacement facilitates advantage.

(3), among squirrel-cage flame proof vee-pulley motor 180, outside component flange 87, outer bearing props up the axiality held round between 89 and component for adjusting ring 82 cylindrical is that the error of 100 millimeters of unit sizes is less than or equal to 0.001 millimeter.Prop up to hold round between 89 and component for adjusting ring 82 cylindrical in order to ensure the outer bearing on insulating element 80 and there is high accuracy axiality.Said structure achieves machine shaft 40 and fore bearing 25 and rear bearing 35 need and bears pure torsion, and triangular driving band 502 produce radial load react to export vee-pulley 90 be can completely bear by no inner-ring bearing 60, only act on insulating element 80, the rotating shaft avoided on machine shaft 40 bears radial load for overhanging section 46;

Drive end bearing bracket 20 arranges insulating element 80, has shared all moment of flexure loads, made machine shaft 40 only bear pure torsion.Owing to meeting under the prerequisite of rated power, can accomplish that the limit is little by asking the diameter of machine shaft 40 in design, only bear pure torsion, meanwhile, owing to meeting under the prerequisite of rated power, can accomplish that the limit is little by asking the diameter of machine shaft 40 in design, only bear pure torsion, meanwhile, because insulating element 80 global shape belongs to hollow short tube, therefore structural rigidity is superpower, can bear larger radial load.Both combine, and the utility model achieves and can do compact by whole motor size, can bear larger radial load again, run more reliable, thus extend the application life of motor.

(4), the utility model by job platform 110 by squirrel-cage flame proof vee-pulley motor 180 with weld spring buffer 145 and combine, solve two hang-ups always perplexing offshore field: power source motor rapid wear problem and oil well installation integrated buffer problem, achieve beyond thought effect simultaneously.
