Abstract
The utility model discloses a generator rotor back cut wedge device, hydro -cylinder, hydro -cylinder fixed establishment, hydro -cylinder top tight mechanism and ejector pin subassembly are gone into including the top, hydro -cylinder fixed establishment will the top is gone into the hydro -cylinder and is fixed on generator rotor, the tight establishment of institution in hydro -cylinder top will push up between an income hydro -cylinder and generator rotor and push up tightly spacingly into the hydro -cylinder, the ejector pin subassembly sets up at a free end of income hydro -cylinder for roof pressure installation slot wedge. When effectively overcoming top mounted slot wedge, the ejector pin subassembly is served and is stuck up, makes the top go into the hydro -cylinder rear portion and produces the trend to the motion of rotor direction, causes the hydro -cylinder slope, and the condition of ejector pin departure avoids causing the damage of unnecessary personnel and equipment, ensures the production safety, the utility model discloses portably, the practicality, safe and reliable, with low costs, effectual.
Description
Technical field
The utility model belongs to non salient pole generator rotor manufacturing technology field, is specifically related to a kind of generator amature inverted draw cut wedge device.
Background technology
Because the fit clearance of metal slot wedge and generator amature dovetail groove is less, very tight, and high-power generator dovetail groove is very long, and common manual mode is difficult to slot wedge to insert and put in place. Generation current machine rotor slot wedge inserted mode be mainly divided into manual squeeze into, special equipment or frock head into. Wherein manual to squeeze into labor strength high, and the large slot wedge of impulsive force is easily out of shape, and workpiece quality is difficult to ensure; Special equipment cost of investment is high, working area large and operation inconvenience; General frock heads into again the little and push rod of strength and easily flies out, and has potential safety hazard. Therefore need a kind of simple in structure, head into strength device large and safe and reliable, easy and simple to handle and complete generator amature slot wedge insertion work.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easy and simple to handle, heads into the large and safe and reliable generator amature inverted draw cut wedge device of strength.
For realizing the technical scheme that the purpose of this utility model adopts be: a kind of generator amature inverted draw cut wedge device, comprise and head into oil cylinder, oil cylinder fixed mechanism, oil cylinder jacking mechanism and push rod component, described in described oil cylinder fixed mechanism general, heading into oil cylinder is fixed on generator amature, described oil cylinder jacking mechanism is arranged on to head into and between oil cylinder and generator amature, will heads into oil cylinder and hold out against spacing, described push rod component is arranged on the free end that heads into oil cylinder, presses slot wedge is installed in order to top.
Described oil cylinder fixed mechanism comprises the hoop component up and down connecting by Connection Block.
The anchor ear group that described upper and lower hoop component is an anchor ear or is made up of more than one anchor ear.
Described oil cylinder jacking mechanism comprises that two ends have respectively right-and-left threaded screw rod and two ingot-shaped nuts.
Described push rod component comprises a square bar, this square bar by adapter sleeve and pin with described in head into oil cylinder and be connected.
The end that heads into of described square bar is square structure, and link is the pylon structure that sidepiece is provided with pin-and-hole.
The utility model is fixed on generator amature by adopting oil cylinder fixed mechanism will head into oil cylinder, and adopt oil cylinder jacking mechanism will head into oil cylinder to hold out against spacing heading into oil cylinder rear portion, thereby while effectively overcoming top tankage wedge, push rod component end upwarps, make to head into oil cylinder rear portion and produce the trend to rotor direction motion, cause oil cylinder to tilt, the situation that push rod flies out, avoid causing unnecessary personnel and equipment damage, ensure production safety. Oil cylinder fixed mechanism adopts hoop component, easy and simple to handle, fixing reliable. Oil cylinder jacking mechanism adopts right-and-left threaded screw rod and two ingot-shaped nuts, right-and-left threaded screw rod is easy and simple to handle, quick on the one hand, convenient adjusting, adopt ingot-shaped nut simultaneously, the cambered surface side of nut matches with the cambered surface that heads into oil cylinder and generator amature, both formed reliable face contact, effectively prevented again that nut was with bolt rotary, very practical. Push rod component adopts square bar, can effectively increase the contact-making surface of push rod and slot wedge, and the mechanical strength of effective guarantee and enhancing push rod, prevents push rod distortion, flies out and hurt sb.'s feelings. The utility model is easy, practical, safe and reliable, and cost is low, effective.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Referring to Fig. 1, generator amature inverted draw cut wedge device of the present utility model, comprise and head into oil cylinder 1, oil cylinder fixed mechanism 3, oil cylinder jacking mechanism 2 and push rod component 4, described oil cylinder fixed mechanism 3 comprises the hoop component up and down connecting by Connection Block, wherein going up hoop component is to be fixed on by 3 anchor ears the anchor ear group forming on Connection Block, head on oil cylinder 1 to hold tightly to be fixed on, lower hoop component is a relatively large anchor ear, hold tightly and be fixed on generator amature 5, will head into oil cylinder 1 and generator amature 5 is fixed together reliably.
Described oil cylinder jacking mechanism 2 comprises that two ends have respectively right-and-left threaded screw rod and two ingot-shaped nuts, the cambered surface side of ingot-shaped nut is fastened on and heads on oil cylinder 1 and generator amature 5, opposite side is connected with screw rod two ends respectively, screw rod middle part arranges hexagonal structure, so that screw rod is rotated to operation by instruments such as spanners, pass through rotary screw, the ingot-shaped nut that makes two ends tightly overhead is heading on oil cylinder 1 and generator amature 5, realizing effectively holds out against spacing to heading into oil cylinder 1, keep heading into oil cylinder 1, active force between the slot wedge of push rod component 4 and quilt top dress and reaction force are point-blank, avoid, cause unnecessary damage.
Described push rod component 4 is arranged on the free end that heads into oil cylinder, press slot wedge is installed in order to top, it comprises a square bar, the end that heads into of square bar is square structure, link is the pylon structure that sidepiece is provided with pin-and-hole, the link of this square bar by adapter sleeve and pin with described in head into oil cylinder and be connected, the pin-and-hole at adapter sleeve and pylon structure place has the through hole matching, by pin, adapter sleeve is connected to locking with pylon structure place, ensures square bar and head into free-ended safe and reliable connection of oil cylinder 1.
Applicant is by advanced development, and by probation, workman is generally reflected well, easy and simple to handle, safe, stable, reliable.
The technical solution of the utility model is not restricted in the scope of embodiment described in the utility model, and the utility model not technology contents of detailed description is known technology.
