The pressing plate is provided with an inner circle of through holes and an outer circle of through holes, the inner circle of through holes corresponds to threaded holes of a planetary head gland of the coal mining machine in position, and the outer circle of through holes corresponds to threaded holes of the planetary head square tenon of the coal mining machine in position; threads of the positioning screws are matched with the threaded holes of the planetary head gland and the threaded holes of the square tenon, and the nuts are arranged at one ends of the positioning screws; the supporting and pushing mechanism supports the pressing plate, the positioning screws are matched with the nuts, and the pressing plate is fixed with the planetary head gland or the planetary head square tenon. By the arrangement, the problem of difficulty in demounting of the gland and the square tenon can be solved, maintenance time can be saved, working efficiency can be improved, and labor intensity of workers can be alleviated.
Description
Technical field
The utility model belongs to coal-winning machine technical field, relates to a kind of coal-winning machine specific purpose tool, relates in particular to a kind of coal-winning machine side of pulling out falcon specific purpose tool.
Background technology
Because coal-face transportation environment is poor and output requirement, after coal-winning machine breaks down, under general condition, be difficult to allow complete machine gug overhaul, mostly need to be at down-hole shutdown inspection.And in coal-winning machine fault, because the phenomenon of float grease seal wearing and tearing leakage of oil and the damage of planetary mechanism cone tooth is more common.There is this type of fault, generally need to unload coal mining machine roller, then pull down planet head side falcon and can change processing.
Existing processing method is to be screwed into top wire hole with screw, ejects gland and square falcon by two top wire holes.And planet head side falcon and gland are due to twice location, in conjunction with very tight, eject very difficult.Can only gug violence dismantle if jackscrew screwed hole stripped thread damages, the square falcon gland that need to more renew, also delays the production time.
In view of this, be nowadays badly in need of a kind of new specific purpose tool side of dismounting falcon of design, to overcome the above-mentioned defect of existing processing mode.
Utility model content
Technical problem to be solved in the utility model is: a kind of coal-winning machine side of pulling out falcon specific purpose tool is provided, can solves coal-winning machine side's falcon gland and square falcon and dismantle difficult problem, increase work efficiency.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of coal-winning machine side of pulling out falcon specific purpose tool, described in the side's of pulling out falcon specific purpose tool comprise: pressing plate, some positioning screws, some nuts, more than one support pushing mechanism;
Described pressing plate arranges inside and outside two ring through hole, and the position of the position corresponding coal-winning machine planet head gland screwed hole of interior ring through hole arranges, and the position of corresponding coal-winning machine planet head side, the position falcon screwed hole of outer ring through hole arranges;
The screw thread of described positioning screw and planet head gland screwed hole, the pairing of square falcon screwed hole, described nut is arranged at one end of positioning screw;
Described support pushing mechanism supports pressing plate, and described positioning screw coordinates with nut, and pressing plate and planet head gland or planet head side falcon are fixed.
As a kind of preferred version of the present utility model, described in the side's of pulling out falcon specific purpose tool comprise: four positioning screws, four nuts.
As a kind of preferred version of the present utility model, described support pushing mechanism is small-sized hydraulic jack, described in the side's of pulling out falcon specific purpose tool comprise two small-sized hydraulic jack.
Principle of the present utility model is: screw rod is by ring through hole in pressing plate, and one end is fixed on gland, and the other end is spacing with nut, then jack is contained in respectively to the pressing plate both sides application of force, struts pressing plate, and pressing plate pulls out planet head gland.After gland is taken out, then screw rod is passed through to the outer ring through hole of pressing plate, one end side of being fixed on falcon is upper, and the other end is spacing with nut, then jack is contained in to the center application of force, struts pressing plate, and pressing plate pulls out planet head side falcon.
The beneficial effects of the utility model are: the coal-winning machine side of the pulling out falcon specific purpose tool the utility model proposes, and can solve coal-winning machine side's falcon gland and square falcon and dismantle difficult problem, save maintenance time, increase work efficiency, alleviate labor strength simultaneously.
