Abstract
The utility model provides a tooling elevator head used in a heat treatment process of a huge rotor of no more than 200MW. The tooling elevator head comprises an elevating cap, a pull rod, a beam, a hanging plate and a cramp frame, wherein the elevating cap (1) is connected with the beam (6) through the pull rod (3); two ends of the beam (6) is connected with the cramp frame which clamps a rotor (9) through the hanging plate (2); and two ends of the cramp frame are fixed by pins. The tooling elevator head can bear the huge motor rotor with the weight greater than 50t, and have simple structural design and convenient manufacture.
Description
Technical field
The utility model relates to rotor manufacturing technology field, the frock elevator head that a kind of 200MW and following large rotor Technology for Heating Processing are used.
Background technology
At present, rotor is one of four big key components of steam power plant, because its condition of work complexity, bear great centrifugal force, because of temperature gradient causes thermal stress, the rotation vibrations cause the very high additional stress of frequency, temporary impact vibration that unit starting, parking and other reasons are produced and torsional stress etc.; As: the 200MW large rotor that super-huge motor uses, material selection: 25Cr2Ni4MoV, weight is 41 tons, axle body diameter 1090mm, axle body length 4110mm, length overall 9780mm.
Because the diameter after this rotor roughing is big, length is long, weight is big, existing frock jig can't lift.
Summary of the invention
For overcoming the deficiencies in the prior art, the frock elevator head that the utility model provides a kind of 200MW and following large rotor Technology for Heating Processing to use.Can load-bearing greater than the Large Rotor of 50t.Its structural design is simple, and is easy to make.
For achieving the above object, the present invention adopts technical scheme as described below:
The frock elevator head that described 200MW and following large rotor Technology for Heating Processing are used, comprise: hang cap, pull bar, crossbeam, link plate and cramp frame, hang cap and connect crossbeam by pull bar, the two ends of crossbeam by link plate with add the cramp frame of holding rotor and be connected, the two ends of cramp frame are by dowel fixes.
The frock elevator head that described 200MW and following large rotor Technology for Heating Processing are used, the rectangular plate of link plate, an end is provided with the circular hole that connects crossbeam on its plate, and the other end is provided with the rectangular opening that connects cramp frame on the plate; Two jiaos of the link plate upper end is fillet, and two jiaos of the link plate bottom is the right angle.
The frock elevator head that described 200MW and following large rotor Technology for Heating Processing are used, cramp frame is the tooth arch of a symmetry, and the middle part of each tooth arch is provided with to add holds the arc of rotor, and the two ends of tooth arch are provided with pin-and-hole.
Owing to adopt aforesaid technical scheme, the utlity model has following good effect:
The frock elevator head that this 200MW and following large rotor Technology for Heating Processing are used.Our factory is accepted the task of the rotor of certain company and is developed.Its structural design is simple, make easy to use, can load-bearing greater than the Large Rotor of 50t.

Embodiment
As shown in Figure 1, 2, 3: the frock elevator head that this 200MW and following large rotor Technology for Heating Processing are used, comprise: hang cap, pull bar, crossbeam, link plate and cramp frame, hang cap (1) and connect crossbeam (6) by pull bar (3), the two ends of crossbeam (6) by link plate (2) with add the cramp frame of holding rotor (9) and be connected, the two ends of cramp frame are by dowel fixes.
The rectangular plate of described link plate (2), its plate top are provided with the circular hole (2.1) that connects crossbeam, and the bottom of plate is provided with the rectangular opening (2.2) that connects cramp frame; Two jiaos of the link plate upper end is fillet, and two jiaos of the link plate bottom is the right angle.
Described cramp frame is the tooth arch (7) of a symmetry, and the middle part of each tooth arch (7) is provided with to add holds the arc of rotor (9), and the two ends of tooth arch (7) are provided with pin-and-hole (8).
When production 200MW and following large rotor are heat-treated technology,, exceeded the load-bearing requirement of former the design's frock because large rotor weight reaches 41t,
At first design and the elevator head of making frock are made of custom-designed link plate and cramp frame, and the designed link plate and the load-bearing of cramp frame have reached 50t.Its structure constitutes by hanging cap (1), pull bar (3), crossbeam, link plate and cramp frame, hang cap and connect crossbeam by pull bar, the two ends of crossbeam by link plate with add the cramp frame of holding rotor and be connected.
During use, to clamp the two ends of the cramp frame of rotor (9) one ends and pass the square hole of link plate (2) respectively by dowel fixes, the circle hole sleeve of two link plates (2) is on crossbeam (6), and pull bar (3) one ends on the crossbeam (6) pass and hang cap (1), and its pull bar pin-and-hole (5) is fixing by pin (4).
During work, by hanging cap (1), pull bar (3) by crossbeam (6), link plate (2) and the cramp frame rotor (9) of slinging.
