Description
Technical field
The present invention relates to winch technical fields, determine within 2.5 weeks the perimeters such as spiral shell position winding friction winch in particular to one kind
Roller.
Background technique
Multirope friction winder is one of the important equipment in mine, is the main conveyance for contacting underground and ground, often
For promoting coal, mine car and spoil, lifts personnel, lower putting material, tool and equipment in coal mine, metallic ore and nonmetallic ore.
Multi-rope friction hoisting winch takes more wirerope on the friction lining for being placed on capstan in the prior art, and hoisting container is suspended on
The both ends of wirerope, when the bottom of container is also hung with balance tail rope, and elevator works, the wirerope of tension must be with certain
Normal pressure be pressed on friction lining, when capstan through retarder by motor band some direction of trend rotate when, in steel
Just very big frictional force is generated between cord and friction lining, wirerope just under the action of this frictional force, follows capstan
It moves together, to realize the promotion and decentralization of container；
The form of endless rope winch transportation system has two kinds of upper rope type and lower rope type, and lower rope type use is more universal.The system is by nothing
The compositions such as pole rope winch, tension device, attachment device and carrying roller, are endless rope winch transportation system diagrams, wirerope is before winch
Square roller lower part enters, and tensioning wheel and tail wheel is bypassed from the rope stretching backward of winch drum lower part again after a few circle dead turns of winding, in envelope
Shape is closed, drives wirerope to make pulling motion by the frictional force of wirerope and roller, mine car is hung on a steel cord from one end, arrived another
Mine car is taken in end or midway, to achieve the purpose that transport.Multirope friction winder is static not in capstan according to Euler's formula
In the case where dynamic, when the quiet pulling force of capstan heavy side wirerope be equal to the underloading quiet pulling force of side wirerope times when, wirerope is just opened
Beginning is slided on friction lining, increases the quiet pulling force of capstan underloading side wirerope, in the situation certain beneficial to load and well depth
Under, the weight of empty container is substantially increased, in the sense, this is unreasonable, because it increases system
Moving-mass and inertia force, but when coefficient of friction is restricted with the numerical value for enclosing cornerite, in order to increase frictional force, in certain feelings
It also has to do so under condition.
Increase coefficient of friction and increases frictional force in the case where enclosing cornerite and quiet pulling force is certain, it is other without bringing
Disadvantage, so explored in terms of improving the coefficient of friction between wirerope and capstan friction lining under normal circumstances,
The suitable wirerope of structure is selected, finding has great friction coefficient, high specific pressure and the new friction material of small abrasion.
Endless rope winch is divided into two kinds of spiral winded type and clamp-type (rope-clamping is wheeled).Spiral winded type winch is to increase to enclose
The most straightforward procedure of cornerite, because it can wind the wirerope of two circles or more on roller.Spiral winded type roller divides again
For parabola shaped roller and scroll drum.Parabola shaped roller and scroll drum into rope, be all by be relatively large in diameter around
Into on roller, due to the effect of angular force component, it is axially moveable each circle rope, is moved to rope stretching at minor diameter.Roller to certain
When one direction rotates, only utilize the half of roller, when winch reversion, then can application cylinder the other half, therefore it is parabola shaped
Roller can be worked with both forward and reverse directions, and scroll drum, can only unidirectional operation.
The advantages of spiral winded type winch, is that structure is simple, the disadvantage is that steel rope abrasion is larger, and in wirerope from big
During half radial minor radius sliding, it is easy " biting " between wirerope, and respectively circle wirerope is easy in sliding process
Roller is worn, it is unreliable to cause to operate.
Clamp-type roller: rope clamp is made of hinged a pair of of fixture block, and fixture block itself has the fork wing, protrudes into roller wheel face with it
Corresponding recesses in, when wirerope forces in rope clamp by radiation direction, fixture block clamps wirerope.On burble point, steel wire
After rope leaves, due to the effect of lower springs, open fixture block.The advantages of this winch is that pulling force is big, and wirerope bending is small, is lacked
Point is to safeguard slightly troublesome, frangibility when rope-clamping spring-mass difference.In the winding process that parabola shaped roller carries out wirerope, steel
Cord is all to wind from major diameter to roller, winds initial stage, since, with the presence of frictional force, wirerope is only between wirerope and roller
Have along around on roller along axially towards one end by screw pitch in order the row of being wound rope, since cylinder surface is in axis section
Interior parabolic, subsequent row diameter of restricting is increasing, only when angular force component is greater than rubbing for each circle wirerope and cylinder surface
Wipe power and when, just force each circle wirerope to move along axial direction to the opposite direction of winding direction, be moved to rope stretching at path,
This in a flash, due to respectively enclosed at major diameter wirerope overall circumference be greater than path at cylinder surface overall circumference, cause all circles
Wirerope and cylinder surface cause each circle wirerope to be in free state there is a phenomenon where moment disengaging, only when these loosenings
Wirerope after sliding at path, disengaging rope tension force effect under, just make loosen each circle wirerope eliminate pine set gap
Roller is locked, normal friction winding state is restored.In the process, wirerope to path inclination squeeze, pine from it is each
Enclose wirerope draw-string locking etc., cause the sliding friction of wirerope stung between rope, rope, the sliding friction of rope and roller, rope and
Roller is detached from throwing switch for moment and causes to move unstable, serious phenomena such as also generating spark etc. of sharply rubbing, therefore is having
Occasion, kinematic accuracy existing for flammable and explosive substance have the occasion of strict demand, and application is all greatly limited.
