Description
Technical field
The utility model relates to a kind of break, specifically a kind of brake of hydroelectric generating set.
Background technique
Hydraulic turbine generator is in stopping process; when rotating speed is reduced to 30 ~ 40% of rated speed; break need be dropped into brake continuously generator amature; tiling scaling loss is made because oil film under low speed is destroyed to avoid promoting bearing; now brake plunger is by brake slipper jack-up; brake slipper withstands brake hoop (press table of generator amature yoke), carries out skidding, thus realize the shutdown of unit to generator amature.Another purposes of break is at installation, maintenance and prestart, by generator rotating part jack-up.
During the brake of prior art, because brake hoop is not an entirety, the brake slipper unbalance stress contacted with it can be caused, vibrate, make the bolt looseness that brake slipper supporting plate is connected with piston, and the bolt loosened can by brake slipper jack-up, during work, brake slipper is due to supporting plate of not fitting, as easy as rolling off a logly cause breaking because of unbalance stress, be even braked ring and knock away and pound and other equipment in wind-tunnel, under this situation, brake slipper supporting plate even can immediate roof on brake hoop, brake hoop is caused serious harm.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and provides the brake of hydroelectric generating set that a kind of structure is simple, safety is practical.
The technical scheme in the invention for solving the technical problem is: this structure is simple, the brake of hydroelectric generating set that safety is practical again, comprise cylinder body, the stop collar of upper piston and lower piston and restriction lower piston range is set in cylinder body, the upper piston that lower piston upper-end surface is arranged inserts chamber and is embedded with butterfly spring, thus make upper piston and lower piston form floating connection, the big nut of the outer installment locking upper piston stroke of cylinder body and handle, on cylinder body, brake slipper supporting plate and brake slipper are installed, brake slipper supporting plate is nested with on the lower spherical male headstock in the sleeping groove being loaded on the setting of upper piston upper-end surface and realizes being combined with the concavo-convex sphere of upper piston, fixed by eccentric holding down bolt and upper piston simultaneously, and be placed in the baffle plate that brake slipper on brake slipper supporting plate arranged by locating stud that brake slipper supporting plate is arranged and brake slipper supporting plate the right and left and locate on brake slipper supporting plate, the secure bond realized with brake slipper supporting plate is fixed by the fixed plate of both sides device before and after screw and brake slipper supporting plate, by support installing brake slipper supporting plate reset tension spring between brake slipper supporting plate and inferior part of the cylinder block.
This brake of hydroelectric generating set provided by the utility model, because piston adopts the Split type structure of upper piston and lower piston floating connection to design, can alleviate the initial brake slipper of braking to the shock of brake hoop, because brake slipper supporting plate adopts concavo-convex sphere to be combined with between upper piston, fix with eccentric holding down bolt and upper piston simultaneously, make brake slipper can adapt to the impact of brake hoop heating distortion in braking process, and brake slipper is fixed by the fixed plate of both sides device before and after screw and its supporting plate, make brake slipper and its supporting plate secure bond integral, eccentric holding down bolt excessive looseness in using process can either be limited and by brake slipper jack-up, avoid brake slipper owing to not fitting supporting plate and cause breaking because of unbalance stress, brake slipper can be stoped to be braked the generation that ring knocks accident away with the locating stud that the fixed plate of both sides device before and after brake slipper supporting plate and brake slipper supporting plate are arranged again, guarantee the safety of other equipment in wind-tunnel, and avoid brake slipper supporting plate immediate roof to cause serious harm to brake hoop on brake hoop.Such break, reliable operation, maintenance workload is little, is the brake of hydroelectric generating set that a kind of structure is simple, safety is practical again.
