Abstract
The utility model relates to a winding engine by planetary differential shifting for a mine, belonging to the transport machinery for mines. In order to meet the severe restriction of sections of mines and the heavy transport task, therefore, a shifting alternating-current winding engine which can adapt to multivariant loads is emergently required. The utility model provides a new style winding engine, which is composed of a turbine box, a roller, a planetary differential shifting mechanism, a high-speed control device, a low speed control device, an alternating-current motor and a machine seat. The planetary differential shifting mechanism providing the speed shifting function is a double-planetary gear driving differential shifting mechanism. The winding engine has the characteristic of constant power with variable speeds and variable loads. The utility model has the advantages of safe operation, simple structure.
Description
The utility model belongs to mining Transport Machinery.
The used haulage gear in mine does not have interchange or direct current drive winch and hydraulic wireline winch outward at present.And can conversion running velocity direct current drive winch and hydraulic wireline winch arranged, but these two kinds of winch equipment are huge, cost an arm and a leg, it is also high that maintenance technique requires, it is also bigger to put off until some time later power.Therefore inconvenience is adopted in the transport of down-hole, mine.The AC electrical winch is again single speed, load is changeable in the transportation of the upper and lower mountain transportation in mine and contact inclined gallery, still have 10 to 20 tons of weights as the weight after being decomposed by equipment such as the mining machinery transported or hydraulic supports, and light have only 1 to 5 ton, resemble mine car etc.Roadway section restriction is extremely tight in addition, and transportation burden is heavy again, a kind ofly can adapt to the changeable speed change AC electrical winch of load so press for.
The purpose of this utility model is at above-mentioned situation, and designing a kind of input is single perpetual motion rate propulsion source, and takeoff output can adapt to the complexity variation of extraneous load, and makes the rotating speed of output and the AC electrical winch that moment of torsion can be adjusted accordingly.To reach the raising conveying efficiency, strengthen safety, simplify the chamber transportation equipment.
Accompanying drawing is the utility model embodiment scheme drawing.Fig. 1, Fig. 2 are two views that planet differential speed change mine winch constitutes scheme drawing.1 worm case wherein, 2 cylinders, 3 planet differential speed-changing mechanisms, 4 control device, 5 low speed control setups, 6 alternating-current motor/AC motors, 7 supports at a high speed.Fig. 3 is the structural representation of dual planetary gear transmission differential speed-changing mechanism.8 output shafts wherein, 9A planetary wheel, 10 gear ring breaker slots, 11 duplex internally toothed annuluss, 12 duplex sun wheels, 13 brake wheels, 14 input shafts, 15B planetary gear carrier, 16B planetary wheel.
Now contrasting embodiment of the present utility model comes formation of the present utility model and speed-change process thereof are described.Planet differential speed change mine winch is mainly by support 7, alternating-current motor/AC motor 6, and high-speed control device 4, low speed control setup 5, planet differential speed-changing mechanism 3, worm case 1 and cylinder 2 are formed (seeing Fig. 1, Fig. 2).Wherein except that planet differential speed-changing mechanism 3 and high speed, low speed control setup the 4, the 5th, the technical characterictic that the utility model is used to make winch possess speed changing function, the effect of other parts is identical with the effect of original mine winch appropriate section.At a high speed, in fact the low speed control setup be exactly simple brake equipment, and the planet differential speed-changing mechanism is the differential speed-changing mechanism that constitutes with the dual planetary gear transmission.Fig. 3 is the structural representation of this dual planetary gear transmission differential speed-changing mechanism.The speed-change process of this mechanism now is described in conjunction with Fig. 3.Rotate when input shaft 14 is subjected to motor drives, must drive duplex sun wheel 12 and rotate, driven by the duplex sun wheel with B satellite gear 16 with duplex sun wheel 12 and 11 while of duplex inner rim ingear A satellite gear 9.If this moment, duplex internally toothed annulus breaker slot 10 was by high-speed control device 4 control brake, then duplex internally toothed annulus 11 does not rotate, A, B two planetary wheels 9,16 will be around 12 rotations of duplex sun wheel, B planetary wheel 16 will drive B planetary gear carrier 15 and brake wheel 13 rotates, to the not influence of rotation of output shaft.And the output shaft 8 that A planetary wheel 9 will drive with its wheel carrier one rotates, and outwards exports with high rotating speed.If duplex internally toothed annulus 11 is not braked, brake wheel 13 is subjected to low speed control setup 5 control brake, so B planetary gear carrier 15 can not rotate, B planetary wheel 16 can not then drive duplex internally toothed annulus 11 and rotate around 12 rotations of duplex sun wheel.This moment, A planetary wheel 9 was subjected to the driving of duplex sun wheel 12 and duplex internally toothed annulus 11 simultaneously, so at the differential of output shaft 8 outputs two rotating speeds, form slow speed of revolution and export, so make winch possess two speed, reached the speed change purpose.
Enforcement of the present utility model, for the mine transportation provides a kind of new type mining winch with speed change varying load constant output characteristic, its variable speed operation safety and steady, and for ease of maintenaince simple in structure and manufacturing, this winch structure also is applicable to the haulage gear of the industries such as civil engineering.
