The specific embodiment
Provide the specific embodiment of the present invention below with reference to accompanying drawing, be used for formation of the present utility model is described further.
Embodiment 1
A kind of pilot-operated type endless rope winch for coal mines of present embodiment is 1-2 with reference to the accompanying drawings, comprise the motor 7 that is used for providing power to winch, motor 7 is connected with planetary gear apparatus 2, planetary gear apparatus 2 is provided with and is used to form zero-speed, at a slow speed with fast speed lock 3 at a slow speed soon, planetary gear apparatus 2 is connected with reductor 4, reductor 4 is connected with and adopts single friction roll, be used to realize the two-way rope stretching of winch and realize forward and reverse all the have reliable constant tensile force and the friction wheel 5 of propulsive effort, friction wheel 5 and brake wheel 8 coaxial direct-connected layouts are equipped with on the brake wheel 8 and adopt normally closed spring band-type brake, the safety brake 6 that hydraulic pressure declutches.The effect of safety brake 6 is normal and improper stopping brake and protections of realization system.The output shaft of described motor 7 adopts invoice serration; Described winch bottom is equipped with base 1.
Principle of work:
Winch provides power by motor 7, adopt the gear and reductor 4 transmissions of secondary planetary gear device 2, under the adjusting of fast lock 3 at a slow speed, make 5 rotations of endless rope winch friction wheel, make between steel rope 9 and the friction wheel 5 and produce friction force, steel rope 9 is realized forward and reverse pulling, and reaches the purpose that transmits weight.
Winch has adopted the transmission of secondary planet train cooperative mechanical reductor, motor 7 output shafts adopt invoice serration, direct connection constant-mesh planetary gear apparatus 2, by a duplex internally toothed annulus in the planetary gear apparatus 2, gear for two stage planetary gear train is installed in the circle, by two covers soon at a slow speed on lock (block brake) 3 and the planetary gear apparatus 2 friction wheel clutch mode carry out speed change, wherein a cover friction wheel passes through splined with first order planetary wheel carrier, another set of friction wheel links by two flat keys and duplex internally toothed annulus.When the electrical motor starting under no load, two soon at a slow speed lock (block brake) 3 all open, constant-mesh planetary gear apparatus 2 idle running, thus friction wheel 5 does not change.During equipment work, under the corresponding adjusting of fast lock 3 at a slow speed, form at a slow speed and move with quick two speed, thereby be transferred to reductor 4, finally be transferred to brake wheel 8, friction wheel 5, winch adopts when underloading fast, adopt at a slow speed during heavy duty, and, realize online dynamic speed adjustment, thereby improved work efficiency soon, need not stop during conversion at a slow speed.
Winch structurally adopts parabola friction wheel 5, can realize the two-way rope stretching of winch, and adopts single friction roll, realizes forward and reverse all have reliable constant tensile force and propulsive effort, no skidding.Sure brake and friction wheel 5 one adopt normally closed spring band-type brake, and hydraulic pressure declutches, but equipment send electricity by the Hydraulic Station feed flow all hydraulic pressure declutch, the device powers down brake spring carries out band-type brake, whole process is stable gently, realizes the reliable of work, has also well avoided the phenomenon that slides down.
Two grades of dynamic speed adjustment functions that adopt planetary gear apparatus 2 to possess, speed governing and the speed change of will shifting gears separately reaches the moment of torsion equilibrium, improved the in-use performance of integral device greatly, and the support equipment running steadily improves service life of equipment and work efficiency.System can utilize the planet speed governing system to realize dynamic smoothing gearshift speed governing in the winch operational process, does not need special the parking to shift gears, and has guaranteed the continuity of producing.
The gearshift speed governing system comprises hydraulic control lock, Hydraulic Station, operating valve, pipeline, adopts fluid control, makes operating personal keep certain distance with winch, has improved safety, and convenient on-the-spot facility location.Lock 3 also adopts the hydraulic control damper brake at a slow speed soon, and is chain with the operation of motor 7, opens a sluice gate automatic band-type brake during parking automatically when realizing the motor operation.
Winch is according to motor, and--the friction wheel device carries out continuous spatial destribution to planetary gear apparatus--two stage speed change case of reductor--.Planet gearing system directly links to each other with the two stage speed change case input shaft of reductor 4, the two stage speed change case output shaft of friction wheel device 5, brake wheel 8 direct connection reductors 4.System is the linear vertically layout of a kind of representative type slender type, forward arranges along railway, has reduced the lateral dimension of equipment effectively, has reduced the space hold of tunnel or chamber.
A kind of pilot-operated type endless rope winch for coal mines of present embodiment, adopt two grades of speed governing of planet and drop-gear box speed change, novel pilot-operated type endless rope winch for coal mines with the tunnel is arranged in the same way can adopt integrated design to take with the horizontal space that reduces winch along the two-way rope stretching of railway, reduced the size of winch chamber effectively, even the special hoist chamber can be set, and easy for installation, save the space, safe, stability is strong.
