Description
Technical field
The invention belongs to rotary wheel of water turbine attaching/detaching apparatus technical field of structures.
Background technique
Pelton turbine rotating wheel is the most important core component of water wheels unit, also is an easily damaged parts simultaneously, need often check, safeguards, repair.If it is improper to safeguard, the fatigue fracture of runner bucket root just possibly take place, cause great production accident, therefore runner being carried out the dismounting repairing is an important process of unit maintenance.Because space, vertical-shaft pelton turbine rotating wheel chamber is narrow; Usually heavy runner is to use chain hois to lift by crane mounting or dismounting, and labor intensity was big when the workman installed and removed runner, when runner connects with hydraulic turbine main shaft; The centering location is difficulty quite, is unfavorable for conventional maintenance, the maintenance of runner.
Along with Pelton wheel constantly develops to high head, big capacity direction, the boundary dimension of rotary wheel of water turbine and weight will increase greatly, and working service requires also strict more, so the runner disassemble and assemble work will become frequently and difficulty more.
Summary of the invention
The object of the invention provides a kind of dismantled and assembled large-sized vertical shaft pelton turbine rotating wheel just for the deficiency that solves existing technology, the hydraulic dismounting device of labor intensity and easy operating when alleviating workman's dismounting runner.
The objective of the invention is to realize through following technological scheme.
Hydraulic dismounting device for vertical-shaft pelton turbine rotating wheel; Comprise the straight-cylinder servomotor that is installed in the hydraulic turbine main shaft center hole, the pivot flange that is positioned at straight-cylinder servomotor top; Be arranged at piston and piston rod in the straight-cylinder servomotor cylinder body; Be installed on the piston rod flange of piston-rod lower end, straight-cylinder servomotor bottom connects with hydraulic turbine main shaft through little flange and adpting flange, offers hydraulic channel in straight-cylinder servomotor bottom; Hydraulic channel is connected with oil gear through oil pipe, is connected with the blind flange that can connect with rotary wheel of water turbine through connecting bolt in piston rod flange lower end.
The present invention is connected with quick release coupling in the hydraulic channel outer end.
The present invention is simple in structure, with chain hois lifting the becoming hydraulic pressure lifting of existing technology, has reduced the setup time of slinging work; Reduced the labor intensity of slinging work; Main is that straight-cylinder servomotor oil cylinder is installed in the hydraulic turbine main shaft central bore, and straight-cylinder servomotor piston rod can remain with hydraulic turbine main shaft and be in identical central position, in the runner assembling and dissembling process; Can accurately realize centering location with the main shaft seam; Improve the lifting precision of runner, made rotary wheel of water turbine disassemble and assemble work convenient, fast, the safety that becomes, satisfied the demand of large-sized vertical shaft pelton turbine rotating wheel dismounting.
Further set forth content of the present invention below in conjunction with Figure of description.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the schematic representation that the present invention lifted by crane and fell rotary wheel of water turbine.
Embodiment
As shown in Figure 1; The present invention includes the straight-cylinder servomotor 2 that is installed in hydraulic turbine main shaft 1 center hole, the pivot flange 11 that is positioned at straight-cylinder servomotor top; Be arranged at piston 12 and piston rod 13 in the straight-cylinder servomotor cylinder body 14; Be installed on the piston rod flange 18 of piston-rod lower end, straight-cylinder servomotor bottom connects with hydraulic turbine main shaft 1 with adpting flange 15 through little flange 6, offers hydraulic channel 17 in straight-cylinder servomotor bottom; Hydraulic channel is connected with oil gear 7 through oil pipe 10, is connected with the blind flange 4 that can connect with rotary wheel of water turbine 3 in piston rod flange 18 lower ends through connecting bolt 19.Be connected with quick release coupling 5 in hydraulic channel 17 outer ends.
The present invention infeeds high pressure oil with oil gear 7 in the servomotor oil cylinder; Convert high pressure oil pressure into hydraulic pressure lift power through the straight-cylinder servomotor; This power can be like a cork promotes runner to connect with hydraulic turbine main shaft or fall runner to be put on the travelling bogie 9, pulls out runner envelope and keeps in repair.When unit ran well, straight-cylinder servomotor 2 and parts thereof were packaged in runner 3 and main shaft 1 center hole by blind flange 4, rotate synchronously with the unit rotating part, do not influence the proper functioning of generator set.
The runner disassemble and assemble work divides following two kinds of situation:
1. pull down runner: with oil pipe 10 oil gear 7 and quick release coupling 5 are connected, shake handle 8 precharge in straight-cylinder servomotor 2 oil cylinders of oil gear, after oil pressure is raised to predetermined value; Remove the shaft link bolt 21 that connects rotary wheel of water turbine 3 and main shaft 1 lower flange; The pressure release handle 20 of adjustment oil gear slowly reduces straight-cylinder servomotor oil cylinder internal pressure, makes runner 3 under the effect of deadweight; Slowly descend; After falling on the travelling bogie 9, by pulling down on the blind flange 4, just can pull out the runner envelope place under repair to piston rod flange 8 to runner with dolly.
2. runner is installed: draw in runner envelope to runner 3 with dolly 9, centering hydraulic turbine main shaft 1 central position is loaded on piston rod flange 18 on the blind flange 4 of runner; With oil pipe 10 oil gear 7 and quick release coupling 5 are connected; Shake handle 8 and in straight-cylinder servomotor oil cylinder, pressurize, slowly runner is mentioned, during near the main shaft lower flange; Rotating wheel; Main shaft lower flange bolt hole is aimed at the attachment hole on the runner, treated that runner promotes the back that puts in place and with shaft link bolt 21 main shaft 1 connected with runner 3 reliably, remove oil pipe and get final product.
