Description
The present invention relates to the active friction wheel formula mine hoist in the mining engineering, these facility have electric notor, be used for driving hoisting cable, the rotor of electric notor is connected with the friction wheel that constitutes cylinder blanket, the stator of electric notor is fixed on to have and supports on structure hollow shaft, that be provided with base support, electric notor is positioned at the cylinder blanket of friction wheel, and by artificial draft system supply cooling cold air.This class active friction wheel formula mine hoist is disclosed, such as 13/14, the 829 page to 832 pages of German patent DE-OS3705567 and German journals (magazine by name " Gluckauf125(1989) issues).
In known active friction wheel formula mine hoist, cold air flows to the both sides of the friction wheel backplate of the utmost point and stator winding through big opening, and the iron core that flows into electric notor through the gap.For importing and discharging coolant air, in the both sides of friction wheel special air conduit cover has been installed, the inside of cover is by a liner of being made up of the incombustible sound deadener that is used to suppress the motor noise.In addition, between the friction wheel of fixing cover and rotation anti abrasive leak sealing spare is arranged, the sealing part is made up of the interior labyrinth type seal that has the brush coating that leak free need not keep in repair.
This known active friction wheel formula mine hoist needs quite high construction expenditure for the coolant air that imports friction wheel and discharge active friction wheel, and the both sides fixing duct shield outer for the friction wheel of rotation requires sizable space.Leak sealing spare between the fixing duct shield and the friction wheel of rotation also will very high expense, because interior labyrinth type seal must have very big diameter, although interior labyrinth seal configuration is simple.
Ventilation noise also has been proved to be shortcoming, ventilation noise is to produce like this, coolant air between duct shield and the friction wheel inside in opening must be imported into the friction wheel backplate, the friction wheel backplate when friction wheel from rotation always substantially perpendicular to the flow direction of coolant air.
Task of the present invention is, a kind of active friction wheel formula mine hoist of the above-mentioned type is provided, and this machine has simple and stable structure, does not have fixing duct shield in the both sides of friction wheel, does not therefore also just need leak sealing between friction wheel and duct shield.
This target is reached by the feature of claim 1, promptly
-importing and the escape route of hollow shaft as the coolant air of electric notor,
-for this purpose, hollow shaft in osed top or leak free friction wheel, have on the one hand cross wall or bulkhead and
-on the other hand, hollow shaft is provided with towards friction wheel in-to-in cooling air inlet and outlet on its circumference.
Solution of the present invention has following advantage,
-do not need the insert (Einhausung) of Koepe formula friction wheel,
-do not need the sealing between insert and the friction wheel;
-(owing to having cancelled insert) only required less space;
-have only less ventilation noise, because coolant air is the internal cavities by friction wheel only.
Owing to not only be used for cable according to hollow shaft of the present invention, and, obviously, pass through in order to make enough big cooling air volume as cooling air channels by electric notor by common mode, must use than the hollow shaft of large diameter.Consequently, necessary installation dimension surpasses the bearing of structural condition, and friction wheel remains on this hollow shaft and running thereon through this bearing.From and increased such advantage, that is, the bearing of friction wheel has the long life-span, thereby improves its smooth rotation (property).
Layout according to active friction wheel gig of the present invention has been proved to be particularly advantageous, and according to this layout, the import of coolant air is positioned at motor stator and deviates from side mutually, and has roughly orientation radially.Reach thus by the special actv. air transfer of friction wheel in-to-in, it can reliably be drained the loss power of 300kw electric notor for example.
On this meaning, when the hollow shaft in friction wheel has the cross-sectional plane extension of the stator support that constitutes electric notor, have good effect, this cross-sectional plane extension has the wall of two relative tilts, is provided with the import and the outlet of coolant air in the wall of these two relative tilts.
Cooling air inlet and outlet preferentially along the circumferential direction are evenly distributed on the wall of hollow shaft, so that keep by friction wheel internal gas flow optimum distribution.
At last, important also have, and the inside face of hollow shaft is provided with body insulation, and noise deadener preferably is so that reduce the self-noise of electric notor.
In the accompanying drawing a unique figure half be left side section drawing, half is a lateral plan, has represented to have the active friction wheel formula mine hoist of architectural feature of the present invention.
The mine hoist that can find out from accompanying drawing has a friction wheel 1, and it evenly spaced four groovings 3 mutually at its cylinder blanket 2 upper supports.
Cylinder blanket 2 is done antitorque the connection in its end with two friction wheel backplates 4, and constitutes friction wheel 1 with backplate 4, has sealed cavity 5 by friction wheel 1.
Each friction wheel backplate 4 is ring-shaped work piecess 7 of settling around friction wheel longitudinal axis 6-6 center, ring-shaped work pieces 7 is round antifriction-bearing box 8, seat is at the outside face of hollow shaft 9 again for antifriction-bearing box, and the two ends of hollow shaft 9 are installed in two supporting bases 10, and supporting base 1 is fixed on again on the basis 11.
Hollow shaft 9 has two end 12 and the middle parts 13 that diameter is bigger that diameter is less.End 12 and middle part 13 are always fused mutually by bevelled wall 14, shown in scheming clearly.The middle part 13 of hollow shaft 9 has constituted the stator of electric notor 15 or the support of stator winding 14, and this support is surrounded by friction wheel 1 fully, promptly is positioned at the cavity of friction wheel.The stator 16 that has the utmost point 17 of electric notor 15 hangs or is fixed on the inside face of the cylinder blanket 2 of friction wheel 1, as shown in the chart clearly.The passage section 18 of two ends 12 of hollow shaft 9 links to each other with the air by-pass passage 19 of cooling, and at big passage section 20 places at the middle part 13 of hollow shaft 9 bulkhead 21 is arranged, and its cuts off the direct communication of passage section 18 of two ends 12 of hollow shaft 9.Along the circumferential direction even (promptly in a side of bulkhead 21 by certain interval) admission port 22 that distributing on the 13 bevelled walls 27 of middle part, and at the corresponding at regular intervals air extractor duct 23 that is furnished with of the opposite side of bulkhead.Admission port 22 and air extractor duct 23 are taked following layout, and promptly admission port and air extractor duct lead to stator 14 and deviate from side mutually, and have one roughly towards friction wheel 1 columniform shell 2 and towards the orienting station of friction wheel backplate 4.
The coolant air of electric notor 15 for example enters the passage section 18 of hollow shaft 9 left ends 12 by the cooling air channels 19 on the left side, 13 turn to admission port 22 through bulkhead 21 at the middle part, as shown shown in the arrow.Coolant air flow through the cavity 5 within the friction wheel 1 and acts on the stator 14 and rotor 16 of electric notor 15 from admission port 22 before arriving air extractor duct 23, the coolant air that comes out from air extractor duct 23 flows into the cooling air channels 19 on the right through the passage section 18 of bulkhead 21 diverted flow to the right part 12 of hollow shaft 9 from the there coolant air.
Be proved to be advantageously, the inside face of hollow shaft 9 scribbles body insulation, the inside face of the friction wheel 1 of preferably noise deadener, and limits 5, the inside face that is cylinder blanket 2 and friction wheel backplate 4 is provided with this class body insulation, thereby reduces the self-noise of electric notor.
The antifriction-bearing box 8 of friction wheel 1 can be sealing member 24 and surrounds on the hollow shaft 9, and sealing member 24 is installed on the end 12 of hollow shaft 9 on the one hand, is close to the end face of ring-shaped work pieces 7 on the other hand, is installed on the antifriction-bearing box 8 through this ring-shaped work pieces friction wheel 1.So just stoped the leakage of air from the cavity 5 of friction wheel 1 quite simply.
Since hollow shaft 9 as with the import and export passage of the coolant air of friction wheel 1 all-in-one-piece electric notor not only as the importing of the connecting cable of electric notor, so its passage section 12 does not allow to be lower than certain minimum value.For this reason, hollow shaft also has corresponding bigger external diameter in two end 12.
Because hollow shaft 9 also is used as the stationary bracket of the antifriction-bearing box 8 of friction wheel 1, so antifriction-bearing box 8 is because structural restriction has surpassed the scantling of structure that will select.This has brought special benefits, and antifriction-bearing box 8 has the long life-span for the antifriction-bearing box of traditional size.
What still will propose at last is, in order to reduce the deadweight of friction wheel 1, friction wheel backplate 4 can be offered numerous opening 25 along its circumferencial direction, the thin cover plate 26 that opening 25 is used in again in the wall closes, thereby the cavity 5 that is used as the friction wheel 1 of coolant air pipeline just is closed, or seal up, thereby avoid leakage air.
