Abstract
The invention discloses a device for disassembling an impeller of a rotor of an induced draft fan, which comprises a travelling crane, a cutting gun and a puller, wherein the travelling crane is used for suspending the rotor of the induced draft fan, the cutting gun is arranged at a hub of the rotor of the induced draft fan and can reciprocate in an arc line around the hub, the puller comprises a jack, a stud bolt and a pressing plate, the bottom end of the jack is fixedly connected to a fixed table, the ejector rod is connected with the pressing plate through the stud bolt, and the pressing plate is connected to the rotor of the induced draft fan. According to the invention, the induced draft fan rotor is vertically hung on the travelling crane, four cutting guns are used for simultaneously reciprocating arc movement, heating and expansion to generate looseness on the periphery of the hub, the puller acts on the fan rotor shaft, and the self-weight effect of the fan rotor shaft is added, so that the impeller can be smoothly withdrawn from the shaft shoulder, the impeller is detached, the convenience in detachment is realized, the use is simple, the problems of difficult detachment and complicated detachment of the induced draft fan rotor in the prior art are effectively solved, and the induced draft fan rotor is assembled by using the prior equipment, and has the characteristics of simple structure and low cost.
Description
Technical Field
The invention belongs to pipeline storage equipment, and relates to a high-pressure pipeline storage container which is convenient to store and easy to place.
Background
The induced draft fan is a mechanical energy input by the motor, improves the gas pressure and discharges the gas, is driven fluid machinery, works at high temperature and high pressure, has poor working environment, is easy to damage, needs frequent maintenance, greatly reduces the efficiency of maintenance equipment because the existing equipment is not easy to detach or is difficult to detach when the impeller of the induced draft fan is detached, and reduces the production efficiency of a thermal power plant.
Disclosure of Invention
The invention aims to solve the technical problems that: the utility model provides a draught fan rotor impeller dismounting device, simple structure, it is convenient to dismantle, convenient to use, equipment maintenance is efficient, has improved the production efficiency of thermal power plant to overcome the not enough of prior art problem.
The technical scheme adopted by the invention is as follows: the utility model provides a draught fan rotor impeller dismounting device, includes driving, cutting torch and puller, the driving is used for suspending the draught fan rotor, the cutting torch is arranged in draught fan rotor hub department, can do reciprocal pitch arc removal around the hub, the puller includes jack, stud and clamp plate, jack bottom fixed connection is on the fixed station, and the ejector pin passes through stud connection clamp plate, the clamp plate is connected to on the draught fan rotor.
Preferably, the cutting guns are four and are uniformly distributed around the hub.
Preferably, the travelling crane is a 10-ton travelling crane.
Preferably, the jack is a 50 ton jack.
The invention has the beneficial effects that: compared with the prior art, the invention vertically hangs the draught fan rotor on the travelling crane, uses four cutting guns to simultaneously carry out reciprocating arc movement and heating on the periphery of the hub, heats for about 25 minutes, causes the hub of the draught fan impeller to thermally expand and loose with the shaft matching surface, uses the puller to act on the shaft of the draught fan rotor, and also uses the dead weight of the shaft of the draught fan rotor to enable the impeller to smoothly withdraw from the shaft shoulder, thereby realizing the disassembly of the impeller.
