Description
Technical field
The present invention relates to a kind of driving device, especially a kind of belt conveyer tensioning winch driving device that is applicable to.
Background technology
Can the tensioning of belt conveyer normally move it and have important role in service life of load-transfer device, tensioning mainly is to realize by rope traction tensioning dolly, the changed course cylinder of load-transfer device is installed on the tensioning dolly, and mobile tensioning dolly can be realized the tensioning of load-transfer device or locking.Existing tensioning technology mainly contains weight tensioning, hydraulic wireline winch tensioning, common winch+three kinds of modes such as oil cylinder tensioning.The weight tensioning is a kind of permanent tension force tensioning mode, its shortcoming: the one, and can not satisfy in the load-transfer device working process and follow the needs of variation because of load change requires tension force, the 2nd, the increase of weight or minimizing operating difficulties, labour intensity is big.The hydraulic wireline winch tensioning can overcome the slack-free shortcoming of weight substantially, but has two aspect problems: the one, and the hydraulic efficiency pressure system low-response can not in time be followed belt tension and be changed; The 2nd, HM Hydraulic Motor efficient is too low, wastes energy.Common winch+oil cylinder tensioning can overcome the shortcoming of above-mentioned two this tensioning modes substantially, but still exist not enough: the one, the piston stroke of oil cylinder is limited, therefore it is also just limited belt tension to be changed followability, particularly belt conveyer length progressively increases now, be increased to several kilometers by hundreds of rice, even tens or tens of kilometer, the trace performance of oil cylinder more can not meet the demands; The 2nd, realize relatively difficulty of " two-point form " tensioning, tension force when promptly starting requires another one tension force during operation, generally adopt pressure relay to address this problem now, but the pressure relay fault rate is too high, and what can not guarantee to produce normally carries out.The shortcoming that a kind of novel winch (code name APW or HDW) can overcome above-mentioned three kinds of tensioning modes had been studied by Australia in recent years, substantially satisfy belt conveyer tensioning requirement, but its complex structure, comparatively difficulty is installed, the unilateral bearing that is adopted has only external several company to produce at present, and cost an arm and a leg, be difficult to satisfy domestic market demand.

Beneficial effect: tensioning winch double-clutch of the present invention adopts two power-transfer clutchs and five gears, realized input shaft direction rotation all the time of winch when putting rope and serving, the frequent switching of motor steering when having avoided winch to put rope and serving, so just can when motor starts, realize frequent serving and put rope, to follow the tension variation of load-transfer device.Owing to be by the cylinder serving or put rope and draw the tensioning dolly, and the Rong Shengliang of cylinder is bigger, therefore can satisfy the variation of load-transfer device in a big way.If excessive velocities when putting rope is in addition directly implemented dynamic brake by motor, limit maximum and put rope speed, prevented the generation of safety misadventure.Main Clutch Friction Plate adopts paper friction material, and the soft start when having realized serving has reduced the impulsive force that steel rope and associated components bore, and prolongs its service life.Output shaft, overriding clutch, sleeve, friction lining group, piston, dish spring and permanent seat etc. have constituted uni-directional brake, have prevented to be rolled onto in the serving process oppositely moving of steel rope behind certain tension force, size that can the accuracy control tensile force.So just can easily realize " two-point form " tensioning, different tension force promptly is provided when belt conveyer starts with operation.Input shaft gear, side clutch input shaft gear and idle pulley triangularity are installed, and idle pulley not only plays the effect that changes rotation direction, as the propulsion source of hydraulic oil pump, have saved the hydraulic oil pump drive motor so simultaneously, have reduced installing space.Tensioning winch transmission structures of the present invention is simple, easy to maintenance, cost is low, highly versatile, dependable performance, is more suitable for the needs of small space under coal mine.Concrete advantage is as follows:
An input shaft direction rotation (serving refers to increase belt tension, and putting restricts refers to reduce belt tension) all the time when 1, employing major-minor power-transfer clutch is realized serving and put the rope action.Master clutch engages during serving, and side clutch unclamps, and the rotation of motor is delivered to output shaft by input shaft, master clutch, master clutch output shaft.Output shaft backward rotation when putting rope, this moment, side clutch engaged, master clutch unclamps, the rotation of output shaft is delivered to the master clutch output shaft by matching spline, be delivered to input shaft by master clutch fixed gear wheel, side clutch fixed gear wheel, side clutch output shaft, side clutch, side clutch input shaft, side clutch input shaft gear, idle pulley and input shaft gear, identical when making steering input shaft still with serving, be that turning to of drive motor is a direction all the time, the frequent switching of motor steering when so just having avoided serving and having put rope.If excessive velocities in the time of can realizing putting rope in addition so directly realizes braking by electric power generation, rope speed is put in restriction, avoids the generation of safety misadventure.
2, the major-minor clutch-lining adopts different materials, when master clutch engages during at serving softlyer, add control clutch and advance oil cylinder working-pressure, the soft start in the time of can realizing serving, the impulsive force that reduces steel rope and relevant device significantly and born prolongs its service life.
3, adopt overriding clutch and friction lining group to constitute uni-directional brake, the overriding clutch endoporus connects by key and output shaft, the outer ring connects by key and sleeve, sleeve other end endoporus links by spline and friction lining group male splines friction lining, friction lining group female splines friction lining and permanent seat link, and permanent seat by screw attachment in casing.Under serving and the stopped status, the friction lining group compresses by dish spring application force, and the overriding clutch outer ring can not be rotated, and inner ring can rotate to a direction, and promptly output shaft can only unidirectional rotation.Output shaft backward rotation when putting rope feeds pressure oil in the oil cylinder that piston and housing constitute, the dish spring is compressed, and the friction lining group is unclamped, and the overriding clutch outer ring can rotate with output shaft.Therefore, overriding clutch, sleeve, friction lining group, piston, dish spring, permanent seat and housing etc. have constituted uni-directional brake.The benefit of uni-directional brake maximum is to have guaranteed that output shaft can not reverse in the serving process, promptly can not reduce belt tension, and energy accuracy control tensile force has satisfied the production demand preferably.
4, adopt idle pulley to drive the hydraulic oil pump rotation, saved the drive motor of pump, simplified complete machine structure.Idle pulley becomes equicrural triangle to install with input shaft gear, side clutch input shaft gear, and idle pulley up.Idle pulley plays on the one hand and guarantees that when putting rope steering input shaft is constant, on the other hand as the propulsion source of hydraulic oil pump, drives hydraulic oil pump and rotates, so that needed pressure oil and lubricating oil to be provided to system.So just saved the drive motor of pump, reduced requirements of installation space, made the structure of whole table apparatus compact more.
