For above problem, be necessary to provide a kind of structure simple, easy to operate unit head.
Summary of the invention
The utility model is in order to provide one can offset top-drive, and this unit head can offset, and can make up a joint in mouse hole position, and in this process, dynamic head main spindle keeps the shape body of vertical rig floor always, makes up a joint more quick, accurately.Coordinate convertible dynamic anchor road operation, dynamic anchor road only need give rise to mouse hole position drilling rod, keeps drilling rod vertical with rig floor, and unit head just can carry out connecing button and operation of linking closely under driller controls, and realizes the Unmanned operation of stacks.
The technical scheme in the invention for solving the technical problem is: one can offset top-drive, comprises coaster assembly, drop handle arm, motor, bearing housing, reinforcement support arm, and coaster assembly is connected with drop handle arm by bearing pin a; Motor is arranged on bearing housing top; Drop handle arm lower end is connected with bearing housing by bearing pin c; Strengthen support arm to be connected with coaster assembly, bearing housing respectively by bearing pin b, bearing pin d, bearing pin a, bearing pin b, bearing pin c, bearing pin d form a parallelogram; Skew fluid cylinder is also provided with between coaster assembly and drop handle arm.
As optimization, described bearing housing bottom connects cock, and the side of bearing housing is provided with back-up tong arm, controls assembly, and back-up tong arm lower end is provided with back-up tong, and back-up tong is arranged on immediately below bearing housing; Motor top is provided with washing pipe; Coaster assembly is provided with assembly pulley, and drop handle arm upper end is provided with drop handle.
As optimization, described coaster assembly integral is L shape, and coaster assembly is provided with reinforcing rib.
As optimization, described motor output shaft front end is hollow-core construction, and main shaft is arranged in the hollow-core construction of motor output shaft front end, is provided with key between main shaft and motor output shaft.
As optimization, described main shaft is provided with taper roller thrust bearing.
As optimization, at least one side of described bearing housing is plane.
During work: skew fluid cylinder stretches out, and drop handle arm rotates to an angle centered by bearing pin a, strengthen support arm simultaneously and also can rotate same angle, unit head is in plumbness all the time.By offseting the stretching, extension of fluid cylinder, making drop handle arm and strengthening support arm parallel rotating, realizing the overall offset action of unit head.
The beneficial effects of the utility model are: compared with prior art, the utility model changes the structure of traditional power head, is applicable to super singles rig, and structure is comparatively pushed up and driven simply, more than unit head function, can realize normal drilling well in drilling well, on unload function that is single, switch cock.Hydraulic jack and parallelogram principle combine, and complete the action of unit head parallel offset, and overall structure is simple, and course of action is stablized, and failure rate is low, automation degree of equipment is high, simple to operate.
