Description
Technical field
The present invention relates to a kind of skyscraper elevator hyper-speed, heavy－duty towing machine, particularly a kind of permanent magnetic synchronous traction machine being convenient to I& M.Belong to towing machine technical field.
Background technology
At present, due to Chinese national economy high speed development, skyscraper continues to bring out, so the demand of customer to skyscraper elevator hyper-speed (command speed is not less than 7.0m/s), heavy－duty (nominal payload is not less than 1600kg) towing machine improves constantly, but because technology is not mature enough, so existing skyscraper elevator hyper-speed, heavy－duty towing machine also have some defects.Once the defect existed for traction sheave and support and connection parts etc. thereof as the applicant is improved, design " ultra-high-speed heavy-loading outer-rotor permanent magnet synchronous traction machine " that publication number is CN101973479A, its structure recorded comprises frame, be assembled in the double bracing main shaft in described frame and stator line bag, be fixed on the rotor block on described main shaft, traction sheave, disc brake apparatus, rotor cover, be assembled in the parts such as the coder of rear end of spindle.Wherein between the main shaft support that is supported on frame two ends by front bearing and rear bearing and front support, the rotor cover arranging the breather port of ventilation and heat is fixed between the double bracing of main shaft, overlap respectively rotor block, brake disc and traction sheave to be connected by rotor and to be fixed together with main shaft, become one-piece construction.Although this ultra-high-speed heavy-loading outer-rotor permanent magnet synchronous traction machine improves stress condition and the load carrying ability of towing machine, improve drive ability, but, find in real-world operation, when traction sheave wearing and tearing need repairing change time, could change after needing the jiggering gear ring of disc brake apparatus and front support all to pull down.In towing machine maintenance sites, due to narrow space, if withdrawing device is incomplete, then because jiggering gear ring and front support are very heavy, so can bring certain difficulty to dismounting.During execute-in-place, once front support pulls down main shaft just lose support, because this end suspender belt of main shaft being sling or propped by backup support, hinder so again shifting out of traction sheave, therefore when safeguarding, some is inconvenient.
In addition, be in " elevator traction sheave " of CN 102849582 A at publication number, its structure recorded comprises annular arrangement wheel rim and is located at the described wheel rim central authorities wheel cylinder coaxial with wheel rim, be connected by annular connecting portion perpendicular to axial direction between described wheel rim with wheel cylinder, one end of described wheel rim is provided with accessory whorl circle, accessory whorl ring outer wall is circumferentially with the grooving of radial depressions, and described accessory whorl circle and wheel rim are split type, are threaded connection connected.This knockdown wheel rim and accessory whorl circle, be convenient for changing the accessory whorl circle being suitable for band grooving accessory whorl circle or damage, need to change whole traction sheave when solving traction sheave fault, gives the technical matters of making troubles that normally works.But, the fixed part that each accessory whorl circle of this elevator traction sheave extends, fix only by screw, nut after grafting, and screw, nut contact surface are cambered surface, this connection mode is unreliable, yielding during accessory whorl circle stand under load; The fixed part that accessory whorl circle extends is thin-walled, processing difficulties, and yielding after processing, manufacturing cost is higher; Because this traction sheave axially can only be dismantled, combine, therefore dismounting difficulty.Notification number is " towing machine " of CN 202625557 U, its record structure comprise rotor, stator, rotating shaft, traction sheave, without sealed bearings, without sealed bearings enclosing cover, without sealed bearings inner cap, rear bearing, rear bearing cover, oil inlet passage, rotating shaft is by being installed on stator without sealed bearings and rear bearing, and oil inlet passage is communicated with the oil pocket without sealed bearings; Without sealed bearings inner cap or be covered with pressure relief opening without outside sealed bearings, pressure relief opening is communicated with without sealed bearings oil pocket and collector tank; Be provided with pressure release screw outside pressure relief opening, pressure release screw axial is hollow, and pressure relief opening is inserted in pressure release screw the inner, and pressure release screw outer end is connected with overflow oil tube, and overflow oil tube is connected with collector tank through rear bearing cover.This towing machine, by increasing automatic discharging pressure power apparatus to the oil pocket without sealed bearings, solves without the liquid state in sealed bearings oil pocket or the oily technical matters entered in stator, rotor or other parts of gaseous state.Find in real-world operation, if draining screw breaks down or overflow oil tube blocking, could keep in repair after needing towing machine main shaft to pull down, cannot remote monitor and control, bring very burden on site maintenance work; Simultaneously due to parts such as needs assembling draining screw, overflow oil tubes, also correspondingly add productive costs.
