Description
Technical field
The present invention relates to a kind of reel of hoist engine more particularly to a kind of multi-lay winding reels of no fold line grooves.
Background technology
Hoist engine is a kind of widely used important lifting means in many fields, and reel is then most important in hoist engine
One of part, its effect are to batch and discharge steel wire rope.Steel wire rope winds the difference of form on reel, can not only influence to roll up
Body product, the length of dead weight and institute's lay winding wire ropes are raised, can also influence the neat degree that steel wire rope is wound on reel, and this
Service life of the point to steel wire rope and the safety using process are most important.Winding form of the steel wire rope on reel is mainly divided
For two classes, i.e. winding of single layer and multi-lay winding.
Winding of single layer is exactly that only winding layer of steel wire rope, this canoe steel wire rope are generally possible to fitly on reel
It is wrapped on entire reel.The surface of some winding of single layer reels machined a helix grooving, be more conducive to guiding steel wire
Rope is fitly wrapped on reel, is avoided steel wire rope and is damaged caused by extruding and friction.But the maximum of this canoe
Problem is that the steel wire rope wound cannot be too long.Because steel wire rope is too long, the length of reel will increase, this necessarily will increase
The volume of hoist engine and dead weight, and many use occasions are restricted to the volume of hoist engine and dead weight.Then, the side of multi-lay winding
Formula just produces.
Multi-lay winding is exactly that two layers and the above steel wire rope are wound on reel.Although this can wind longer steel wire rope,
And reduce the volume of hoist engine, mitigate the dead weight of hoist engine, but produce mutually squeeze between levels steel wire rope simultaneously, grind
It wipes, the easily chaotic problem of row's rope, this has seriously affected the service life of steel wire rope.Because when being wrapped several layers of steel wires on reel
When rope, upper layer steel wire rope necessarily squeezes lower layer's steel wire rope, and upper layer rope strand is angled with lower layer rope strand, this makes steel wire
The abrasion of rope is especially serious.Even if mandrel surface machined helix grooving, this abrasion can not be made to be mitigated.First layer
Although steel wire rope can be fitly wrapped on entire reel, when being wound into the end of reel, second layer steel wire cannot be guided
Rope is along reel fitly wraparound, because not forming the grooving neatly wound for second layer steel wire rope, it can only be by certain
Angle be pressed in naturally on following layer of steel wire rope, this is just difficult to ensure neat winding.So helix grooving is not suitable for
The multi-lay winding mode of steel wire rope.
Then, people in two directions seek solution.One of direction is to have invented rope-arranging mechanism, makes multi-lay winding
Steel wire rope marshalling be possibly realized, but and unresolved upper layer steel wire rope be all pressed on lower layer's steel wire rope by certain angle
Problem squeezes, friction exists in the same old way.Direction second is that having invented the reel with dual slope grooving, this reel adds on surface
Mandrel surface, i.e., be divided into four parts, wherein non-conterminous two parts by a kind of grooving of special shape of work by circumferential length
It machined and be parallel to flange, between each other also parallel grooving, and this two-part grooving is staggered half grooving in an axial direction
Distance；It machined in other non-conterminous two parts and be not parallel to flange, but connect the parallel grooving that its both sides is staggered
The fold line grooves with angle of inclination；Because there is two fold line grooves, therefore referred to as dual slope grooving.Because two fold line grooves
Length is shorter than the length of two parallel groovings very much, so upper layer steel wire rope is when returning, it is largely to crouch in lower layer's steel wire rope
It is formed by grooving, only at two shorter fold line grooves, upper layer steel wire rope is just folded by certain angle with lower layer's steel wire rope
Pressure, this can not only make the steel wire rope marshalling of multi-lay winding, also dramatically reduce extruding between upper and lower layer steel wire rope and
Friction, to extend the service life of steel wire rope.
Dual slope rope groove drum solves steel wire rope multi-lay winding marshalling and mitigates levels steel wire rope and squeezes well
The problem of pressure, friction is current best multi-lay winding reel.But it is there are one critical defect, exactly fabricates very tired
It is difficult.The either machine-shaping directly on reel is also formed into this grooving, split type drum sheath, all keeps away not open
The difficulty of processing that fold line grooves are brought.Current adoptable processing method, generally only numerical control milling and casting, but numerical control milling
A large amount of material removal need to be fallen, efficiency is low, takes that more, cost is too high；And casting method precision is relatively low, and generally use brittleness
Material, intensity are relatively low.Therefore, the use of this superior roll receives very big influence.
Invention content
Present invention solves the technical problem that be to provide a kind of no fold line grooves, can not only make steel wire rope multi-lay winding and
Marshalling mitigates the extruding and friction of levels steel wire rope, moreover it is possible to which convenient, efficient processing and manufacturing has intensity height, precision
The reel of the features such as high, at low cost.
The present invention uses following technical scheme.
Multi-lay winding reel without fold line grooves, is made of reel core and drum sheath, the two is bolted, weld or
Other methods link into an integrated entity.
The material of reel core and drum sheath is the toughness materials such as carbon steel, steel alloy, stainless steel, aluminium alloy, with obtain compared with
High intensity and machinability；The material of drum sheath can also be engineering plastics, glass fibre, composite material etc., this will regard tool
The service condition of body determines.
Reel core is made of cylinder, flange and spool shaft, integral by welding method group；In cylinder close to the end of flange
Portion, there are the notches of disengaging steel wire rope.
Drum sheath is made of grooving sleeve and each two pieces of light sleeve, they are separated by arrangement along the drum surface of reel core.Often
The length of part grooving sleeve covering cylinder accounts for about the 40% of cylinder circumferential length, and center of circle angle α is about 144 °；Every light sleeve covers
The length of cap tube body accounts for about the 10% of cylinder circumferential length, and center of circle angle β is about 36 °.
The width of drum sheath is equal with the spacing on the inside of two flange of reel core, which generally takes the integral multiple of grooving width again
Add the width of half of grooving.
Grooving sleeve in drum sheath is process by integral tubular Workpiece Turning, and outer surface machined several be parallel to
A boss is processed into end face, between each other also parallel semicircle grooving, the position of last half of grooving width, boss it is outer
Diameter is equal with the coiling diameter of second layer steel wire rope bottom supporting point；The good grooving sleeve of vehicle is divided into pieces in an axial direction.
Light sleeve in drum sheath is also process by integral tubular Workpiece Turning, and outer diameter is smooth cylindrical surface, and
It is equal with the grooving base diameter of grooving sleeve；The good light sleeve of vehicle is divided into pieces in an axial direction；Light sleeve wherein
End, also there are the notches of disengaging steel wire rope.
Two pieces grooving sleeve reversed arrangement on the cylinder of reel core, i.e., the boss one on two pieces grooving sleeve is on a left side
Side, another on the right, the grooving both made is just staggered the distance of half of grooving.
When assembling, the notch on light sleeve will not only be directed at the notch on cylinder, will also be with the grooving phase on grooving sleeve
Neighbour, rather than it is adjacent with the boss on grooving sleeve.In this way, the initiating terminal of steel wire rope can be fixed in cylinder, from lacking
Steel wire rope in mouthful out can smoothly enter into grooving.
When this reel lay winding wire ropes, the steel wire rope from notch out initially enters the 1st grooving sleeve and notch phase
In adjacent grooving；After turning over the 1st grooving sleeve, steel wire rope has been come at the 1st light sleeve；Due to not restricting on light sleeve
Slot, steel wire rope continue to wind along former direction under the action of pulling force；After turning over the 1st light sleeve, steel wire rope has come the 2nd
At grooving sleeve；Due to the 2nd grooving sleeve and the 1st grooving sleeve reversed arrangement, so its boss is located at initiating terminal, and
Grooving is just staggered with the 1st grooving sleeve at a distance from half of grooving；When steel wire rope is come at the 2nd grooving sleeve, steel wire
The center line of rope is necessarily contacted with the boss edge of the 2nd grooving sleeve, it is made to slide to the 2nd grooving set lower than boss automatically
In the grooving of cylinder, the steel wire rope in the 1st grooving sleeve is caused to be staggered at a distance from half of grooving；Then, in the 1st light set
One section is formd on cylinder, and there are one the steel wire ropes of the broken line shape of angle with end face, although without fold line grooves that is, on light sleeve,
But steel wire rope has still wound out the shape of fold line grooves；After turning over the 2nd grooving sleeve, steel wire rope has come the 2nd
At light sleeve, steel wire rope continues to wind along former direction under the action of pulling force；After turning over the 2nd light sleeve, steel wire rope comes again
To at the 1st grooving sleeve；The center line of steel wire rope is contacted with the steel wire rope that the 1st grooving sleeve has been wound, and keeps it automatic
In the grooving for sliding to adjacent not steel wire rope, the steel wire rope in the 2nd grooving sleeve has been staggered again at a distance from half of grooving；
Then, the steel wire rope of one section of broken line shape is formd again on the 2nd light sleeve.So rotation is gone down, and steel wire rope is by reel
Initiating terminal has fitly been wound into the end of reel.
When being wound into the end of reel, steel wire rope has arrived flange inner side edge on the 2nd grooving sleeve, can not continue
Broken line shape is formed on 2nd light sleeve, can only be continued to wind along former direction, climbed up the 1st grooving under the action of pulling force
In the grooving that the boss of sleeve is constituted with lay winding wire ropes, the flange inner side edge in reel end forms the 2nd layer of steel wire rope
The 1st circle；With the rotation of reel, steel wire rope has been come at the 2nd grooving sleeve；But as previously mentioned, the 2nd grooving sleeve
Last 1 grooving is to be close to flange inner side edge and wound steel wire rope, and the steel wire rope for continuing winding is difficult center to center
Be pressed on lower layer's steel wire rope, can only be wound in the 1st article and the 2nd article of grooving reciprocal on the 2nd grooving sleeve of slide-in of negative direction
Steel wire rope be formed by grooving, formd on the 1st light sleeve one section with reversed angle broken line shape steel wire
Rope；Similarly, when steel wire rope has been come at the 1st grooving sleeve, steel wire rope also can automatic negative direction the 1st grooving set of slide-in
Lay winding wire ropes are formed by grooving on cylinder, form one section of fold-line-shaped with reversed angle again on the 2nd light sleeve
The steel wire rope of shape.So rotation is gone down, and steel wire rope has fitly been wound into the initiating terminal of reel by the end of reel.
During the winding process, since most of steel wire rope is to crouch in the grooving of grooving sleeve, or crouch by lower layer's steel wire
Rope is formed by grooving, and plays guiding function to the broken line shape steel wire rope at light sleeve.This can not only make grooving sleeve
The steel wire rope marshalling at place, moreover it is possible to make the steel wire rope marshalling laminated by certain angle at light sleeve, to effectively mitigate
Extruding between levels steel wire rope and friction extend the service life of steel wire rope.
If necessary to using if other diameter steel cords, only need to change corresponding grooving sleeve.
Usefulness of the present invention is, without fold line grooves on reel, to keep processing and manufacturing convenient, efficient, significantly drop
