Description
Technical field the utility model relates to a kind of lifting speed governing winch, especially mine lift winch.
Background technology is present, and it is automatically controlled that the mine lift winch adopts wound rotor asynchronous motor to add resistance mostly, changes the running velocity of winch by convert resistance.This winch speed adjustable range is limited, and the automatically controlled energy consumption of resistance is big, and resistance is automatically controlled, and influenced by the mine working environment bigger, explosion-proof hoist particularly, the accessory combination of its electrical equipment gearshift is many, and split setting, battle array are bigger, cost up to 100,000 yuan/cover, fault rate height, maintenance are complicated.
01249243.4 number patent has proposed a kind of " mechanical stepless speed-regulating winch ", its advantage is speed-regulating range width, realized infinite speed variation, explosion-proof performance is good, saves energy, dismounting are easy to assembly, easy to maintenance, but has following weak point:
1, the heat radiation of speed regulation device and sealing effectiveness are undesirable.
2, need to use the manual operation speed belt, not only labor strength is big, and the speed instability of output.
Summary of the invention goal of the invention of the present utility model provides a kind of improved type mechanical stepless speed-regulating winch, promptly No. 01249243.4 patent is improved, and it is bad to solve heat radiation and sealing effectiveness, and the bigger problem of labor strength.
Technical scheme is the differential stepless speed-regulating device that will be made of sun wheel, satellite gear and planetary wheel carrier, inner gear and bearing support and is packed in the same casing by the speed reduction gearing that two pairs of gears are formed, forms the speed governing retarder jointly.In addition, on the fly wheel governor periphery, load onto hydraulic pressure block brake, to replace manually-operated speed belt drg by hydraulic ram control.
The characteristics such as speed-regulating range width, infinite speed variation, explosion-proof performance are good except that having for the utility model, saves energy, dismounting are easy to assembly, easy to maintenance, also have following characteristics:
1, because speed governing and the two kinds of devices that slow down are packed in the same casing, so compact conformation, be convenient to sealing and take cooling measures such as oil cooling, air cooling, good heat dissipation effect.
2, owing to take hydraulic brake system, need not therefore to alleviate labor strength with manually holding the speed belt control lever all the time.
3, because the artificial speed belt braking force of grasping of hydraulic braking force rate is much stable, so output speed can be stabilized in operation in the fixed rotating speed, improved complete machine reliability of operation and safety.
4, enlarged field of application, except that the mine, other needs the field of winch also to be applicable to building industry etc.
Description of drawings Fig. 1 is improved type mechanical stepless speed-regulating winch structure figure
Fig. 2 is a speed governing retarder top plan view
Fig. 3 is speed governing retarder transmission principle figure
Fig. 4 is hydraulic pressure block brake and hydraulic ram constructional drawing
The specific embodiment as shown in the figure, the utility model includes the reel 1 that is contained on the main shaft 3, the output shaft 9 of speed governing retarder 4 is connected with main shaft 3, input shaft 16 outer ends of speed governing retarder 4 are connected with electrical motor 6 main shafts, input shaft 16 the inners are fixed with sun wheel 13, add up to the satellite gear 12 wheel shaft movable set by separately more than 2 on planetary wheel carrier 17 right-hand members, 12 whiles and sun wheel 13 of satellite gear, inner gear 11 engagements, inner gear 11 is packed in bearing support 14 inner chamber left ends, bearing support 14 inner chamber right-hand members are sleeved on the input shaft 16 through ball bearing of main shaft, difference is that satellite gear 17 left ends and brake axle 19 are connected, miniature gears 21 on the brake axle 19 and 22 engagements of the big gear wheel on the tween drive shaft 25, miniature gears 23 on the tween drive shaft 25 and 24 engagements of the big gear wheel on the output shaft 9, bearing support 14, brake axle 19, tween drive shaft 25 and output shaft 9 all are installed on the casing 18 through ball bearing of main shaft, bearing support 14 outer ends are fixed with fly wheel governor 15, and the hydraulic pressure block brake 5 by hydraulic ram 7 controls is housed on fly wheel governor 15 peripheries.In the present embodiment, brake axle 19 outer ends are fixed with work system driving wheel 20, be equipped with on work system driving wheel 20 peripheries by the hydraulic pressure block brake 5 of hydraulic ram 7 ' control '.In addition, be equipped with by hydraulic ram 8 controlled emergency braking devices 2 on the reel 1 one side peripheries.
Principle of work of the present utility model and using method are as follows:
When the delivery quality that reduces hydraulic ram 7, when making drg 5 be totally released fly wheel governor 15, electrical motor 6 drives sun wheel 13, satellite gear 12, inner gear 11 and fly wheel governor 15 high speed revolutions through input shaft 16, planetary wheel carrier 11 is slack because of the associating resistance that is subjected to brake axle 19 and speed reduction gearing, and promptly reel 1 is not driven.When the delivery quality driving drg 5 that increases hydraulic ram 7 was held fly wheel governor 15 tightly gradually, the rotating speed of fly wheel governor 15 was by high step-down, and the rotating speed of inner gear 11 is step-down thereupon, and the resistance that satellite gear 12 is produced becomes big.Simultaneously, the horsepower input of electrical motor 6 is constant with it, and the propulsive effort that sun wheel 13 promotes satellite gear 12 rotations is constant, and the part of propulsive effort then promotes planetary wheel carrier 17 rotations, drives brake axle 19, gear 22～24 and reel 1 rotation.Along with the rising of oil pressure, the rotating speed of fly wheel governor 15 is by high step-down, and the rotating speed of reel is uprised by low gradually.When the oil pressure of hydraulic ram 7 stabilized to certain value, the rotating speed of reel 1 then stabilized to a definite value.When the oil pressure actuated drg 5 of hydraulic ram 7 is held fly wheel governor 15 fully tightly and made it motionless, planetary wheel carrier 17 will rotate with maximum speed of revolution, and reel 1 is rotation at full throttle thereupon also.
When winch normally moves, do not make reel 1 stall immediately if do not want to utilize speed regulation device, can increase so hydraulic ram 7 ' oil pressure, driving drg 5 ' hold service braking wheel 20 fully tightly to make it motionless, brake axle 19 is not rotated, gear 21～24 stalls, reel 1 stall.
Run into emergency situation if winch is in operation, can stop so to hydraulic ram 8 fuel feeding, hydraulic ram 8 decompressions will cause accident brake 2 actions, make reel 1 stall.
