Abstract
The utility model relates to an extractor and especially relates to a special slip ring extractor. The extractor comprises a jack oil cylinder and a jack thrust rod. The jack thrust rod is placed in the jack oil cylinder. A protruding terminal of one side of a fixing sleeve is fixedly connected with the jack oil cylinder and the other side is fixedly connected with a connection plate. A dummy shaft passes through the fixing sleeve and the connection plate and is placed in a centre hole of the jack thrust rod. A double-headed screw is fixedly connected on the connection plate. One side of the fixing sleeve and an outer side of the jack oil cylinder are provided with a screw thread. The fixing sleeve is fixedly connected with the jack oil cylinder through the screw thread. The fixing sleeve is fixedly connected with the connection plate through a nut. The double-headed screw is fixedly connected with the connection plate through a screw hole. One end without the screw thread of the dummy shaft is placed in the centre hole of the jack thrust rod. One end with the screw thread is fixedly connected in the centre hole of a slip ring fixing shaft. By using the extractor, each direction of the slip ring is under an uniform stress so that the slip ring can be well extracted and is not damaged. Cost is saved and an efficacy is increased.
Description
Technical field
The utility model relates to a kind of extractor, especially a kind of special-purpose slip ring puller.
Background technology
Need before HXN5 locomotive 5GMG201E1 type main and backup generator complete machine disintegrates slip ring is pulled out first, and slip ring and rotating shaft are interference fit that itself is made of lug, as with drawing bell to extract, is easy to each lug is damaged.Slip ring self with screwed hole centre distance less, without volume little, stressed uniform power transmission dummy shaft can connect, and needs to make special tooling.
The utility model content
Damage easily the deficiency of slip ring in order to overcome existing extractor, the utility model provides a kind of special-purpose slip ring puller.
The technical scheme that its technical problem that solves the utility model adopts is: special-purpose slip ring puller, comprise jack cylinder and jack thrust bar, the jack thrust bar places in the jack cylinder, fixed cover one side-prominent end is fixedly connected with jack cylinder, opposite side is fixedly connected with tie-plate, dummy shaft passes fixed cover and tie-plate places in the centre bore of jack thrust bar, and double threaded screw is fixedly connected on the tie-plate.
According to another embodiment of the present utility model, comprise that further fixed cover one side and the jack cylinder outside all is provided with screw thread, fixed cover is fixedly connected with jack cylinder by screw thread.
According to another embodiment of the present utility model, comprise that further fixed cover is fixedly connected with tie-plate by nut.
According to another embodiment of the present utility model, comprise that further double threaded screw is fixedly connected with tie-plate by screw, screwhole position and slip ring position consistency.
According to another embodiment of the present utility model, comprise that further double threaded screw quantity is 4.
According to another embodiment of the present utility model, comprise that further the not threaded end of dummy shaft places in the centre bore of jack thrust bar, a threaded end is fixedly connected in the centre bore of slip ring fixed axis.
The beneficial effects of the utility model are, this extractor makes the slip ring all directions stressed evenly, can extract slip ring is intact, and do not damage slip ring.Save cost, improved effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of special-purpose slip ring puller;
1. jack cylinders among the figure, 2. jack thrust bar, 3. fixed cover, 4. tie-plate, 5. dummy shaft, 6. double threaded screw, 7. nut.
Embodiment
The structural representation of special-purpose slip ring puller such as Fig. 1, special-purpose slip ring puller, comprise jack cylinder 1 and jack thrust bar 2, jack thrust bar 2 places in the jack cylinder 1, fixed cover 3 one side-prominent ends are fixedly connected with jack cylinder 1, opposite side is fixedly connected with tie-plate 4, dummy shaft 5 passes fixed cover 3 and places in the centre bore of jack thrust bar 2 with tie-plate 4, double threaded screw 6 is fixedly connected on the tie-plate 4, fixed cover 3 one sides and jack cylinder 1 outside all are provided with screw thread, fixed cover 3 is fixedly connected with jack cylinder 1 by screw thread, fixed cover 3 is fixedly connected with tie-plate 4 by nut 7, double threaded screw 6 is fixedly connected with tie-plate 4 by screw, screwhole position and slip ring position consistency, double threaded screw 6 quantity are 4, and the not threaded end of dummy shaft 5 places in the centre bore of jack thrust bar 2, and a threaded end is fixedly connected in the centre bore of slip ring fixed axis.
First fixed cover 3 is tightened on the jack cylinder 1, the outside screw by fixed cover 3 and tie-plate 4 is fastening good with both again.Then dummy shaft 5 screwed ends are screwed in the centre bore with the slip ring fixed axis, the centre bore that the more not threaded end of dummy shaft 5 is passed fixed cover 3 and tie-plate 4 inserts in jack thrust bar 2 centre bores, to be threaded onto simultaneously tie-plate 4 and be pulled out in the hole of slip ring with double threaded screw 6 at last, after all working is ready to, start jack, the active force that is produced by the relative motion of removing jack thrust bar 2 and jack cylinder 1 separates slip ring from the slip ring fixed axis, this extractor makes the slip ring all directions stressed evenly, can extract slip ring is intact, and do not damage slip ring.Save cost, improved effect.
