Abstract

The utility model provides a stepless speed-regulation device of mine hoisting winch. The safety break and working break are merged of the domestic produced mine stepless speed-regulation winch, and manual lever are all used to control the tightness of the break line thereby controlling the speed of the drum. Although the device is simply structured, it is not failure of control. The double joint gear of the utility model is connected with an internal gear and a gear on a regulating shaft. A working break wheel is equipped at the output terminal of a planetary carrier. An annular sleeve is fixed to a large gear of the double joint gear and the annular sleeve has radial and axial gaps of the outer diameter of the internal gear thereby the internal gear can float. The end face of the sun wheel-axle teeth is supported by ball-end part to form auxiliary float. Differential planet wheel employs floating of the internal gear plus auxiliary floating of the sun wheel thereby it has the features of smoothness, efficient transmission, convenient maintenance, simple manipulation and superior performance.

The stepless speed-regulating device of mine lift puffer

Technical field

The utility model relates to a kind of stepless speed-regulating device of mine lift puffer.

Background technology

At present, mining infinite speed variation puffer, safety arrestment and the service braking of domestic production unite two into one, and all are the speeds that comes index drum with the tightness that hand lever is controlled brake band.Though this device is simple in structure, can not reach the purpose of Failure Control.Be out of order etc. as unexpected power failure, circuit, the manual lever of cylinder stopped is not in place, weight on the cylinder will fall down, cause and let car fly away, dangerous, moreover the existing unit that produces this product has been cancelled safety mark by national mining product safety sign office, mustn't produce and sell the lifting puffer of this structure again.

Summary of the invention

The purpose of this utility model provides a kind of stepless speed-regulating device of mine lift puffer.

The technical scheme that its technical matters that solves the utility model adopts is: the sun wheel shaft (2-5) by planetary differential (2) is connected with motor (1) by elastic clutch; Link to each other with gear (3-1) on the drum spindle with the train of reduction gears of planetary differential (2); Output external part in pinion carrier is equipped with work system driving wheel (2-7); Link to each other with gear on inner gear (2-3), the speed governing axle (2-2) by dual gear (2-13).

The inner gear of planetary differential floats, annular cover (2-14) is fixed on the big gear wheel of dual gear (2-13), annular cover (2-14) and inner gear (2-3) external diameter radially, axially all gapped, inner gear is floated; The end face of sun wheel shaft (2-5) tooth has ball-end part to head on, and constitutes auxiliary floating.

Pinion on the big gear wheel of dual gear and the speed governing axle (2-2).The output gear (2-12) of planet differential retarder (2) links to each other with gear (3-1) on the drum spindle.

The beneficial effects of the utility model are, planet differential mechanism adopts the unsteady sun wheel that adds of inner gear to assist unsteady, it is very steady to turn round, and noise is little, the driving efficiency height, life-span is long, safe and reliable, easy to maintenance, its speed governing is simple to operate, good speed adjustment features is a kind of desirable pure mechanical stepless speed-regulating device.

Among the figure: 1. motor, 1-1. plunging joint, 2. planetary differential, 2-1. fly wheel governor, 2-2. speed governing axle, 2-3. inner gear, 2-4. satellite gear, 2-5. sun wheel shaft, 2-6. pinion carrier, 2-7 work system driving wheel, 2-8,2-9,2-10,2-11,2-12. gear, 2-13. dual gear, 2-14. annular cover, 3. cylinder, 3-1. gear, the 3-2. drg.

The specific embodiment:

Sun wheel shaft 2-5 with planetary differential 2 is connected with motor 1, output gear 2-12 with the transmission train of reduction gears of planetary differential 2 links to each other with the gear 3-1 of drum spindle, output external part at the pinion carrier 2-6 of planetary differential is equipped with the work system driving wheel, on the work system driving wheel block brake is housed.External part at the speed governing axle 2-2 of planetary differential is equipped with fly wheel governor 2-1, and block brake is housed on fly wheel governor equally.Fluid power pusher brake 3-2 is housed on cylinder.

As shown in Figure 1, the utility model is to be connected with planetary differential 2 by plunging joint 1-1 by motor 1, and planetary differential 2 passes through output gear 2-12 and links to each other with gear 3-1 on cylinder 3 main shafts.Fluid power pusher brake 3-2 is housed on the cylinder 3, and when main frame was switched on, this drg 3-2 opened, and when main frame cut off the power supply, this drg 3-2 checked cylinder.Prevent that main frame from letting car fly away.

Fig. 2 is the embodiment that realizes infinite speed variation, Fig. 3 is the P portion enlarged drawing of Fig. 2, the sun wheel shaft 2-5 of planet differential retarder 2 is connected with motor 1 by the elastic clutch 1-1 of elastic clutch or band brake wheel, and the tooth portion of sun wheel shaft 2-5 to hold be floating structure.Gear 2-9, the gear 2-10 of gear 2-8 on the pinion carrier 2-6 of planet differential retarder 2 by train of reduction gears, gear 2-11, gear 2-12 are connected with gear 3-1 on the drum spindle.Cancelled the big gear wheel on China's use lifting puffer cylinder decades, made its more reasonable structure.Output external part at the pinion carrier 2-6 of planetary differential is equipped with work system driving wheel 2-7, on the work system driving wheel block brake is housed.The inner gear 2-3 of planetary differential floats, its structure is not drop out by annular cover 2-13 control inner gear 2-3, annular is overlapped 2-14 to be fixed on the big gear wheel of dual gear 2-13 with hexagonal bar iron, annular cover 2-14 and inner gear 2-3 external diameter radially, axially all gapped, constitute inner gear and float, this kind ralocatable mode is simple in structure and axial dimension is little.Inner gear 2-3 and satellite gear 2-4 engagement.

Pinion on the miniature gears of dual gear 2-13 and inner gear engagement, big gear wheel and the speed governing axle 2-2, this is the raising speed transmission, the moment of torsion on the favourable reduction speed governing axle is equipped with fly wheel governor at the external part of speed governing axle 2-2, and block brake is housed on the fly wheel governor.Service braking and speed governing braking are controlled by hand by lever.Operate two handles by the operator, just can realize controlling lifting, transfer the various running statees of load.As rotating speed, by the running of right handles Control work brake wheel 2-7 by left handle control fly wheel governor 2-1.When left handle not during the application of force, promptly fly wheel governor is in free state, and motor 1 can starting under no load (disregarding mechanical wear).The power that applies when left handle from small to large and service braking when decontroling, this moment fly wheel governor 2-1 rotating speed from high to low, the rotating speed of cylinder 3 is also just from small to large.When fly wheel governor 2-1 is checked by block brake, the rotating speed of cylinder 3 reaches maxim (being rated speed of rotation), the power that applies when left handle is from big to small the time, and promptly the drg on the fly wheel governor 2-1 progressively leaves fly wheel governor, this moment fly wheel governor rotating speed from low to high, the rotating speed of cylinder 3 also just from big to small, realize the purpose of infinite speed variation, and service braking is used for cylinder and is in operation, and need stop in certain position, the work system driving wheel is checked, and this moment, fly wheel governor will be decontroled.
