The transmission process of winch described in the utility model is: electrical motor 1 is given transmission of power the involute outer spline of transmission shaft 5 one ends by connecting tooth cover 2, make transmission shaft 5 revolutions, the high speed level sun wheel 7-1 of transmission shaft 5 other ends passes to level planetary wheel 7-2 at a high speed with power, be in relative static conditions owing to make the high speed level internally toothed annulus 7-6 of one with transmission gear ring 17, the at high speed level planetary wheel 7-2 of institute rotates, level tooth rest 7-5 revolution at a high speed.Level tooth rest 7-5 makes its revolution by the low speed turbine stage sun wheel 8-1 that the transmission of one end involute internal gear is meshed with it at a high speed, the low speed turbine stage planetary wheel 8-2 that low speed turbine stage sun wheel 8-1 transmission is meshed with it, because make the low speed turbine stage internally toothed annulus 8-6 of one with rotating cylinder 16 relative static, the revolution of low speed turbine stage planetary wheel 8-2 promotes low speed turbine stage tooth rest 8-5 revolution, because low speed turbine stage tooth rest 8-5 is to be in transmission connection by the involute outer spline and the transmission gear ring 17 1 end involute inner splines of one end, thereby transmission transmission gear ring 17 revolutions, the involute outer spline of the involute inner spline of transmission gear ring 17 other ends and main shaft 6 spindle noses is to be in transmission connection, 6 revolutions of transmission gear ring 17 transmission main shafts.
Winch described in the utility model has four kinds of operating modes when utilization and operation, existing division is as follows:
First kind of operating mode: roller device 9 transfixions, electrical motor 1 have started normal moving the commentaries on classics.Electrical motor 1 running, transmission gear ring 17 transfixions, rotating cylinder 16 revolutions, velocity modulation turns round with disk brake lock 11-1, velocity modulation separates with disk brake lock 11-1 with velocity modulation with braking brake shoe 11-2, velocity modulation makes velocity modulation throw off with disk brake lock 11-1 with braking brake shoe 11-2 and velocity modulation with disk spring in the pressure medium compression cylinder in the brake cylinder 11-3; Disk brake lock 10-1 transfixion, brake cylinder 10-3 is because of no pressure, and disk spring release will be braked brake shoe 10-2 and be compressed disk brake lock 10-1 in the brake cylinder 10-3, and because of the friction brake force effect, disk brake lock 10-1 is braked.
Second kind of operating mode: roller device 9 turns round with rated speed of rotation; velocity modulation disk brake lock 11-1 transfixion; electrical motor 1 normally turns round; low speed turbine stage tooth rest 8-5 revolution; transmission gear ring 17 normally turns round; main shaft 6 revolutions; roller device 9 normally turns round; rotating cylinder 16 transfixions; at this moment, the velocity modulation velocity modulation of brake equipment 11 disk brake lock 11-1 transfixion, velocity modulation no pressure in the brake cylinder 11-3; velocity modulation discharges with disk spring in the brake cylinder 11-3; velocity modulation is compressed velocity modulation disk brake lock 11-1 with braking brake shoe 11-2, and because of the friction brake force effect, velocity modulation is braked with disk brake lock 11-1; meanwhile work, work and safety catch 10 are in the state of declutching.Pressure medium is compressed disk spring in the brake cylinder 10-3, drives braking brake shoe 10-2 and retreats, and breaks away from disk brake lock 10-1, and disk brake lock 10-1 is in non-braking mode, and disk brake lock 10-1 loses the braking constraint and freely turns round.Roller device 9 freely turns round.
The third operating mode: winch is in the acceleration start-up course.Actuating motor 1, treat electrical motor 1 start finish to advance normal moving the commentaries on classics after, harmonious ground operator hydrodynamic pressure pressure-modulation valve 10-5 and velocity modulation hand-hydraulic pressure-modulation valve 11-5 simultaneously.Disk spring in constantly rising brake cylinder 10-3 operation pressure gradually reduces brake cylinder 10-3, its working thrust makes braking brake shoe 10-2 reduce gradually the braking force of disk brake lock 10-1, up to till the brake off time, the medium operation pressure of brake cylinder 11-3 is used in the modulation that meanwhile underspeeds uniformly with the velocity modulation of brake equipment 11, velocity modulation discharges because of the medium operation pressure reduces gradually gradually with disk spring in the brake cylinder 11-3, the thrust of velocity modulation with braking brake shoe 11-2 is strengthened gradually, brake fully with disk brake lock 11-1 up to velocity modulation, roller device 9 enters normal operation, and this moment, velocity modulation was in braking mode with brake equipment 11.
The 4th kind of operating mode: winch enters quiescence from even deceleration of normal operation.At this moment, work and safety catch 10 enter braking mode from the state of declutching, and velocity modulation enters the braking mode that declutches with brake equipment 11 from braking mode.
Reconcile simultaneously hand-hydraulic pressure-modulation valve 10-5 and velocity modulation hand-hydraulic pressure-modulation valve 11-5 harmoniously, at the charge oil pressure that reduces braking pumping plant 10-4 gradually, the pressure medium of brake cylinder 10-3 reduces gradually, disk spring pressure in the brake cylinder 10-3 discharges gradually, thrust to braking brake shoe 10-2 strengthens gradually, braking brake shoe 10-2 also strengthens gradually to the braking force of disk brake lock 10-1, roller device 9 evenly slows down when stopping gradually, the liquid supply pressure of modulating with brake cylinder 11-3 that builds up speed gradually makes velocity modulation be compressed gradually with brake cylinder 11-3 inner chamber disk spring, velocity modulation also reduces gradually with the thrust that braking brake shoe 11-2 is subjected to, it also descends gradually to the braking force of velocity modulation with disk brake lock 11-1, up to brake off, velocity modulation disk brake lock 11-1 freedom of entry operative condition.
