Abstract
The utility model discloses heavy duty detergent stator bearing shell dismounting device, it comprises screw rod (1), and screw rod (1) top is connected with nut (2); Nut (2) below is connected with hollow hydraulic jack (3), hollow hydraulic jack (3) below is connected with support member (4), and support member (4) middle part is by through hole connecting screw rod (1); Support member (4) below is provided with pressing plate (5), and pressing plate (5) is by screwed hole (6) connecting screw rod (1), and pressing plate (5) below is connected with hold-down nut (7).The utility model to nut active force by hollow hydraulic jack, is made nut drive screw rod and pressing plate to move straight up, thus is released from guide vane sleeve by stator bearing shell by pressing plate; By hollow hydraulic jack to support member active force, support member is made to compress guide vane sleeve by seam.The utility model can not only improve removal efficiency, also has the effect preventing stator bearing shell from damaging.
Description
Technical field
The utility model relates to the provision for disengagement of a kind of stator bearing shell, particularly a kind of provision for disengagement can dismantling stator bearing shell efficiently and safely.
Background technology
When water turbine units overhaul, need the stator bearing shell of wearing and tearing is dismantled, but due to stator bearing shell in its natural state external diameter be greater than warp in guide vane sleeve, under the expanding force effect of stator bearing shell, connective stability between stator bearing shell and guide vane sleeve is comparatively strong, and stator bearing shell is not easily dismantled.And in unloading process, a part of stator bearing shell first pulls out from guide vane sleeve, recovers nature; Another part stator bearing shell is still arranged in guide vane sleeve, by the reaction force of stator bearing shell to internal strain; Easy damage stator bearing shell.Therefore, there is the problem of the lower and more fragile stator bearing shell of removal efficiency in the work of current dismounting stator bearing shell.
Utility model content
The purpose of this utility model is, provides a kind of heavy duty detergent stator bearing shell dismounting device.The utility model can not only improve removal efficiency, also has the effect preventing stator bearing shell from damaging.
The technical solution of the utility model: heavy duty detergent stator bearing shell dismounting device, comprise screw rod, screw tip is connected with nut; Be connected with hollow hydraulic jack below nut, below hollow hydraulic jack, be connected with support member, by through hole connecting screw rod in the middle part of support member; Be provided with pressing plate below support member, pressing plate, by screwed hole connecting screw rod, is connected with hold-down nut below pressing plate.
In aforesaid heavy duty detergent stator bearing shell dismounting device, described support member is cylindric, and support member inside is provided with cavity, is provided with seam bottom support member.
In aforesaid heavy duty detergent stator bearing shell dismounting device, described pressing plate upper surface is provided with back-up ring, is also provided with elastic washer between pressing plate and hold-down nut.
Compared with prior art, the utility model to nut active force by hollow hydraulic jack, is made nut drive screw rod and pressing plate to move straight up, thus is released from guide vane sleeve by stator bearing shell by pressing plate; By hollow hydraulic jack to support member active force, make support member compress guide vane sleeve by seam, prevent moving up and down and double swerve of guide vane sleeve.In addition, the setting of back-up ring can give stator bearing shell radially outer support force, offsets the active force of guide vane sleeve, prevents stator bearing shell deformed damaged.Therefore, the utility model can not only improve removal efficiency, also has the effect preventing stator bearing shell from damaging.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of pressing plate;
Fig. 3 is fundamental diagram of the present utility model.
Being labeled as in accompanying drawing: 1-screw rod, 2-nut, the hollow hydraulic jack of 3-, 4-support member, 5-pressing plate, 6-screwed hole, 7-hold-down nut, 8-cavity, 9-seam, 10-back-up ring, 11-elastic washer, 12-stator bearing shell, 13-guide vane sleeve.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.Heavy duty detergent stator bearing shell dismounting device, form as shown in Figures 1 to 3, comprise screw rod 1, screw rod 1 top is connected with nut 2; Be connected with hollow hydraulic jack 3 below nut 2, below hollow hydraulic jack 3, be connected with support member 4, by through hole connecting screw rod 1 in the middle part of support member 4; Be provided with pressing plate 5 below support member 4, pressing plate 5, by screwed hole 6 connecting screw rod 1, is connected with hold-down nut 7 below pressing plate 5.
Described support member 4 is cylindric, support member 4 inside is provided with cavity 8, is provided with seam 9 bottom support member 4, and the internal diameter of support member 4 is greater than the internal diameter of guide vane sleeve 13, support member 4 connects the upper surface of guide vane sleeve 13 by seam 9, and the height of cavity 8 is greater than the height of stator bearing shell 12; Described pressing plate 5 upper surface is provided with back-up ring 10, and pressing plate 5 upper surface connects the bottom of stator bearing shell 12, and back-up ring 10 connects the inner side bottom stator bearing shell 12, is also provided with elastic washer 11 between pressing plate 5 and hold-down nut 7.
During dismounting as shown in Figure 3, first support member 4 is connected to the upper surface of guide vane sleeve 13, seam 9 can prevent guide vane sleeve double swerve; Then pressing plate 5 is connected the bottom of stator bearing shell 12, pressing plate 5 is connected with screw rod 1 by the screwed hole 6 in the middle part of it, the screw rod 1 below pressing plate 5 connects successively elastic washer 11 and hold-down nut 7 again, guarantees the connection between pressing plate 5 and screw rod 1; Back-up ring 10 on pressing plate 5 snaps in the inner side bottom stator bearing shell 12, plays the effect of support guide vane bearing shell 12, prevents stator bearing shell 12 under the active force of guide vane sleeve 13, deformation occurring; Finally start hollow hydraulic jack 3, hollow hydraulic jack 3 gives 2 one, nut power straight up, to support member 4 one reaction forces, nut 2 is made to drive screw rod 1 and pressing plate 5 to move by the direction of arrow shown in Fig. 3, thus release stator bearing shell 12, make support member 4 compress guide vane sleeve 13 simultaneously, prevent guide vane sleeve 13 from moving with stator bearing shell 12, facilitate the dismounting of stator bearing shell 12.
The height of cavity 8 is greater than the height of stator bearing shell 12, is positioned at the cavity 8 of support member 4 after stator bearing shell 12 can be made to depart from guide vane sleeve 13 completely; The internal diameter of support member 4 is greater than the internal diameter of guide vane sleeve 13, after can for convenience detachly completing, in support member 4, takes out stator bearing shell 12.After having dismantled, unscrew hold-down nut 7, then screw off pressing plate 5, just can take out stator bearing shell 12 easily in support member 4, conveniently dismantle next time.
