Abstract
Official abstract text for this publication.
The present application provides a combined stator wedge driver and bar jacking tool for positioning a stator bar and a stator wedge into place along a slot of a stator core. The combined stator wedge driver and bar jacking tool may include a bar jacking tool to drive the stator bar into the slot and a stator wedge driver to drive the stator wedge on top of the stator bar in the slot. The bar jacking tool and the stator wedge driver extend from a common housing.
First claim
Opening claim text (preview).
We claim: 1. A combined stator wedge driver and bar jacking tool for positioning a stator bar and a stator wedge into place along a slot of a stator core, comprising: a bar jacking tool to drive the stator bar into the slot, wherein the bar jacking tool comprises a bar hydraulic cylinder, a bar ram driven by the bar hydraulic cylinder, and a pair of anchor jaws operable by the bar ram; a stator wedge driver to drive the stator wedge on top of the stator bar in the slot; and the bar jacking tool and the stator wedge driver extending from a common housing. 2. The combined stator wedge driver and bar jacking tool of claim 1 , wherein the bar ram extends through the common housing. 3. The combined stator wedge driver and bar jacking tool of claim 1 , wherein the slot comprises a groove therein and wherein the pair of anchor jaws comprises a hook sized to accommodate the groove. 4. The combined stator wedge driver and bar jacking tool of claim 1 , wherein the stator wedge driver comprises a wedge driver hydraulic cylinder. 5. The combined stator wedge driver and bar jacking tool of claim 4 , wherein the stator wedge driver comprises a wedge driver ram driven by the wedge driver hydraulic cylinder. 6. The combined stator wedge driver and bar jacking tool of claim 5 , wherein the stator wedge driver comprises a driving block driven by the wedge driver hydraulic cylinder and the wedge driver ram. 7. The combined stator wedge driver and bar jacking tool of claim 1 , wherein the stator wedge driver drives a stator slide between the stator bar and the stator wedge. 8. The combined stator wedge driver and bar jacking tool of claim 1 , wherein the stator wedge driver drives a stator strip between the stator bar and the stator wedge. 9. The combined stator wedge driver and bar jacking tool of claim 1 , wherein the stator wedge driver drives a stator ripple spring between the stator bar and the stator wedge. 10. The combined stator wedge driver and bar jacking tool of claim 1 , wherein the stator wedge driver drives a stator slide, a stator strip, and a stator ripple spring between the stator bar and the stator wedge. 11. The combined stator wedge driver and bar jacking tool of claim 1 , wherein the stator wedge driver drives a plurality of stator wedges into place along the slot. 12. A method of positioning a stator bar and a stator wedge into place along a slot of a stator core, comprising: positioning a combined stator wedge driver and bar jacking tool about the slot; hydraulically driving the stator bar into the slot via a bar jacking tool of the combined stator wedge driver and bar jacking tool, wherein the bar jacking tool comprises a bar hydraulic cylinder, a bar ram driven by the bar hydraulic cylinder, and a pair of anchor jaws operable by the bar ram; and hydraulically driving the stator wedge on top of the stator bar in the slot via a stator wedge driver of the combined stator wedge driver and bar jacking tool. 13. A combined stator wedge driver and bar jacking tool for positioning a stator bar and a stator wedge into place along a slot of a stator core, comprising: a hydraulic bar jacking tool to drive the stator bar into the slot, wherein the hydraulic bar jacking tool comprises a bar hydraulic cylinder, a bar ram driven by the bar hydraulic cylinder, and a pair of anchor jaws operable by the bar ram; a hydraulic stator wedge driver to drive the stator wedge on top of the stator bar in the slot; and the hydraulic bar jacking tool and the hydraulic stator wedge driver extending from a common housing. 14. The combined stator wedge driver and bar jacking tool of claim 13 , wherein the bar ram extends through the common housing. 15. The combined stator wedge driver and bar jacking tool of claim 13 , wherein the hydraulic stator wedge driver comprises a wedge driver ram and a driving block. 16. The combined stator wedge driver and bar jacking tool of claim 13 , wherein the hydraulic stator wedge driver drives a stator slide, a stator strip, and a stator ripple spring between the stator bar and the stator wedge.
