Detailed description of the invention
Fig. 1 is the structural schematic diagram for taking connection pin assembly；
Fig. 2 is the three-dimensional figure schematic diagram of TRT rotor.
In figure: 1, pressing plate；2, nut；3, hydraulic top；4, pull rod.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of TRT rotor blade positioning transformations connection
Pin disassembly is provided through pull rod 4 with connection pin assembly, including pressing plate 1 is taken on pressing plate 1, the surface of pull rod 4 and positioned at pressing plate 1
Top be arranged with nut 2, the two sides of 1 bottom of pressing plate are provided with hydraulic top 3.
A kind of method for dismounting of TRT rotor blade positioning transformations attachment pegs, including TRT rotor blade positioning transformations connection
Outbound is dismantled with connection pin assembly is taken, using following steps:
S1, apparatus for placing prepare: welding for steel structure being fabricated to the device of horizontal positioned TRT rotor, while guaranteeing level
Placing TRT rotor can be rotated in disassembly positioning transformations attachment pegs with 360 °.
S2, tool prepare: it is (auxiliary to prepare magnetic drill, 50T hydraulic top, oxy-acetylene full set heating device and auxiliary equipment
Helping facility includes: angle grinder, file, hand hammer, flat chisel, tinted glasses, copper needle, gloves, magnifying glass, loosening agent, steel seal code, silk
Cone, drill bit, monkey spanner, 42CrMo pole, steel pressing plate).
S3, rotor blade are removed: TRT rotor is lain in a horizontal plane in can be torn open on rotating device by welding for steel structure production
Do sequence steel seal code labeling on rotor blade before point, guarantee blade and the same position of spacer (point I on a TRT rotor,
II grade blade, every I grade has 30 blades, 60 positioning attachment pegs, after carrying out position mark on rotor, according to what is assembled in the past
Sequence finds out the blade finally assembled, determines and turns to the beginning TRT rotor is horizontally arranged using steel construction rotating device after blade
The blade of the corresponding disassembly in 12 positions of clock).
S4, removing surface: cleaning rotor surface exposes attachment pegs position, if attachment pegs rotor surface welds, using angle
Grinding machine cleaning polishes exposing pin location, then stamps centre bore, using magnetic drill, bores and removes attachment pegs, attachment pegs length is
320mm first selects φ 16mm drill bit to remove 180mm by rotor surface horizontal drilling, and centre empties 2/3rds, is adopted by rotor surface
Expanded by magnetic drill into 50mm with φ 20mm drill bit, then tapping again.
S5, take out movable vane piece positioning transformations attachment pegs: preparation takes connection pin assembly, and mating φ 22mm pull rod 4 is mounted on
In positioning attachment pegs after mantle fiber, 1 central punch of pressing plate covers on pull rod 4, and fixed φ 22mm nut 2 cooperates 4 He of steady brace
3 position size of hydraulic top is adjusted in pressing plate 1, and concrete operations are as follows:
In positioning attachment pegs after pull rod 4 being horizontally arranged at mantle fiber, pressing plate 1 is installed on pull rod 4, has measured hydraulic top
φ 22mm nut 2 is fixed in 3 positions, then installs hydraulic top 3, two sides with the rotor surface for being equipped with positioning attachment pegs in pressing plate 1
Being applied for pressure simultaneously is 40 megapascal, and the positioning attachment pegs that centre empties 2/3 generate contraction distortion and counteract movable vane piece and positioning
The deflection generated between mutual cooperation face in use between pin finally taps 4 top of pull rod using sledgehammer, hears sound
Acoustic compliance benefit takes out movable vane piece positioning transformations attachment pegs, if when taking movable vane piece positioning transformations very big attachment pegs, and pull rod 4
In positioning attachment pegs after being horizontally arranged at mantle fiber, pressing plate 1 is installed on pull rod 4, has measured the fixed φ 22mm in 3 position of hydraulic top
Then nut 2 installs hydraulic top 3 in pressing plate 1 and positioning attachment pegs rotor surface, it is 40 megapascal that two sides are applied for pressure simultaneously,
The positioning attachment pegs that centre empties 2/3 generate contraction distortion and counteract between movable vane piece and positioning pin phase interworking in use
The deflection generated between conjunction face, when finally tapping 4 top of pull rod without hearing that sound is difficult to take out using sledgehammer, using oxygen second
Alkynes full set heating device, M3 side of heater blade pedestal quickly remove the very big attachment pegs of blade positioning transformations.
In conclusion it is dynamic to shorten rotor with connection pin assembly is taken for TRT rotor blade positioning transformations attachment pegs disassembly
Blade positions the time of attachment pegs disassembly, reduces labor intensity of workers, improves labor efficiency, reduce rehabilitation expense, makes
The relative dimensions parameter and performance indicator of TRT rotor reach former design requirement, produce for rationally group and provide guarantee.
