Description
Technical Field
The invention relates to a winding drum of a winding machine, in particular to a multi-layer winding drum without broken line rope grooves.
Background
Windlass is an important hoisting device widely used in many fields, while a reel is one of the most important parts in windlass, the function of which is to reel and release wire ropes. The difference of the winding form of the steel wire rope on the winding drum not only can influence the volume and the dead weight of the winding machine and the length of the wound steel wire rope, but also can influence the winding uniformity of the steel wire rope on the winding drum, and the winding uniformity is important to the service life of the steel wire rope and the safety of the use process. The winding form of the wire rope on the drum is mainly divided into two types, i.e., single-layer winding and multi-layer winding.
The single-layer winding is to wind only one layer of steel wire rope on the winding drum, and the steel wire rope can be wound on the whole winding drum in a regular way. The surface of the single-layer winding drum is provided with a spiral rope groove, so that the wire rope can be guided to be wound on the drum neatly, and the damage of the wire rope caused by extrusion and friction is avoided. However, the biggest problem with this winding is that the wound wire rope cannot be too long. Because the wire rope is too long, the length of the winding drum is increased, which inevitably increases the volume and the dead weight of the winch, and many use occasions have restrictions on the volume and the dead weight of the winch. Thus, a multi-layer winding is produced.
The multi-layer winding is to wind two or more layers of steel wire ropes on a winding drum. Although the long steel wire ropes can be wound, the volume of the winch is reduced, and the dead weight of the winch is reduced, the problem that the upper layer steel wire ropes and the lower layer steel wire ropes are mutually extruded and rubbed, and the rope arrangement is easy to be confused is generated, so that the service life of the steel wire ropes is seriously influenced. Because the upper layer wire rope is necessarily pressed against the lower layer wire rope when several layers of wire rope are wound on the drum, and the upper layer strands are at an angle to the lower layer strands, this makes the abrasion of the wire rope particularly serious. Even if the surface of the drum is provided with spiral rope grooves, this wear cannot be reduced to some extent. Although the first layer of wire rope can be wound on the whole winding drum in order, when the first layer of wire rope is wound on the end part of the winding drum, the second layer of wire rope cannot be guided to wind back in order along the winding drum, and because a rope groove for the second layer of wire rope to wind in order is not formed, the first layer of wire rope can only be naturally pressed on the lower layer of wire rope at a certain angle, and therefore the regular winding is difficult to ensure. Therefore, the spiral rope groove is not suitable for the multi-layer winding manner of the wire rope.
Thus, people seek solutions in both directions. One of the directions is to invent a rope arranging mechanism to enable the arrangement of the multi-layer winding steel wire ropes to be tidy, but the problem that the upper layer steel wire ropes are all pressed on the lower layer steel wire ropes at a certain angle is not solved, and extrusion and friction exist as the same. The second direction is to invent a winding drum with double-fold line rope grooves, the winding drum is provided with a special-shaped rope groove on the surface, namely, the surface of the winding drum is divided into four parts according to the circumferential length, two parts which are not adjacent to each other are provided with rope grooves which are parallel to the flange and are also parallel to each other, and the rope grooves of the two parts are staggered by a distance of half of the rope grooves along the axial direction; two parts which are not adjacent are processed with fold line rope grooves with inclination angles which are not parallel to the flange but are used for connecting the parallel rope grooves with two staggered sides; because there are two broken line grooves, they are called double broken line grooves. Because the lengths of the two broken line rope grooves are much shorter than those of the two parallel rope grooves, most of the upper layer steel wire ropes are laid in the rope grooves formed by the lower layer steel wire ropes when returning, and only at the two shorter broken line rope grooves, the upper layer steel wire ropes and the lower layer steel wire ropes are overlapped at a certain angle, so that the multi-layer winding steel wire ropes can be orderly arranged, the extrusion and friction between the upper layer steel wire ropes and the lower layer steel wire ropes are greatly reduced, and the service life of the steel wire ropes is prolonged.
The double-fold line rope groove winding drum well solves the problems that the steel wire ropes are orderly wound in multiple layers and the extrusion and friction of the steel wire ropes at the upper layer and the lower layer are reduced, and is the best multilayer winding drum at present. However, it has a fatal defect that it is very difficult to manufacture. The processing difficulty caused by folding line rope grooves is avoided no matter the winding drum is directly processed and molded on the winding drum or the split winding drum sleeve with the rope grooves is manufactured. The existing processing method generally only comprises numerical control milling and casting, but the numerical control milling needs to cut off a large amount of materials, and has low efficiency, much time consumption and high cost; the casting method is low in precision, and generally adopts brittle materials, and is low in strength. The use of such a good reel is therefore greatly affected.
Disclosure of Invention
The technical problem solved by the invention is to provide the winding drum which has no broken line rope grooves, can enable the steel wire ropes to be wound in multiple layers and orderly arranged, lighten the extrusion and friction of the steel wire ropes at the upper layer and the lower layer, can be conveniently and efficiently processed and manufactured, and has the characteristics of high strength, high precision, low cost and the like.
The invention adopts the following technical scheme.
The multilayer winding reel without broken line rope groove consists of reel core and reel sleeve connected integrally via screw, welding or other method.
The materials of the winding drum core and the winding drum sleeve are all ductile materials such as carbon steel, alloy steel, stainless steel, aluminum alloy and the like so as to obtain higher strength and workability; the material of the roll sleeve can also be engineering plastics, fiberglass, composite materials, etc., which are determined according to the specific use case.
The winding drum core consists of a drum body, a flange and a winding drum shaft, and is integrated by a welding method; and a notch for entering and exiting the steel wire rope is reserved at the end part of the cylinder body, which is close to the flange.
The winding drum sleeve consists of two parts, namely a rope groove sleeve and an optical sleeve, which are arranged at intervals along the surface of the drum body of the winding drum core. The length of each rope groove sleeve covering the cylinder body is about 40% of the circumferential length of the cylinder body, and the included angle alpha of the circle center is about 144 degrees; the length of each optical sleeve covering the cylinder is about 10% of the circumferential length of the cylinder, and the included angle beta of the circle center is about 36 degrees.
The width of the winding drum sleeve is equal to the distance between the inner sides of the two flanges of the winding drum core, and the value is generally the whole multiple of the width of the rope groove and the width of the half rope groove.
The rope groove sleeve in the winding drum sleeve is formed by turning an integral tubular material, a plurality of semicircular rope grooves which are parallel to the end face and parallel to each other are formed in the outer surface of the rope groove sleeve, a boss is formed at the width position of the last half rope groove, and the outer diameter of the boss is equal to the winding diameter of a supporting point at the bottom of the second layer of steel wire rope; the rope groove sleeve is divided into a plurality of pieces along the axial direction.
The optical sleeve in the winding drum sleeve is also formed by turning an integral tubular material, and the outer diameter of the optical sleeve is a smooth cylindrical surface and is equal to the diameter of the bottom of the rope groove sleeve; the turned optical sleeve is divided into a plurality of pieces along the axial direction; the end of one optical sleeve is also provided with a notch for entering and exiting the steel wire rope.
The two rope groove sleeves are reversely arranged on the barrel body of the winding drum core, namely, the bosses on the two rope groove sleeves are arranged on the left side and the right side, so that the rope grooves of the two rope groove sleeves are just staggered by a distance of half of the rope grooves.
When assembled, the notch on the light sleeve is not only aligned with the notch on the barrel, but also adjacent to the rope groove on the rope groove sleeve, but not adjacent to the boss on the rope groove sleeve. Therefore, the initial end of the steel wire rope can be fixed in the cylinder body, and the steel wire rope coming out of the notch can smoothly enter the rope groove.
When the winding drum winds the steel wire rope, the steel wire rope coming out of the notch firstly enters the 1 st rope groove sleeve and the rope groove adjacent to the notch; after the steel wire rope passes through the 1 st rope groove sleeve, the steel wire rope arrives at the 1 st optical sleeve; because the optical sleeve is not provided with a rope groove, the steel wire rope continues to wind along the original direction under the action of tensile force; after the steel wire rope passes through the 1 st optical sleeve, the steel wire rope arrives at the 2 nd rope groove sleeve; since the 2 nd rope groove sleeve and the 1 st rope groove sleeve are reversely arranged, the boss is positioned at the starting end, and the rope groove and the 1 st rope groove sleeve are just staggered by a distance of half of the rope groove; when the steel wire rope arrives at the 2 nd rope groove sleeve, the center line of the steel wire rope is necessarily contacted with the boss edge of the 2 nd rope groove sleeve, so that the steel wire rope automatically slides into the rope groove of the 2 nd rope groove sleeve lower than the boss, and the steel wire rope in the 1 st rope groove sleeve is staggered by a distance of half a rope groove; then, a section of the steel wire rope in a broken line shape with an included angle with the end face is formed on the 1 st optical sleeve, namely, the optical sleeve is not provided with broken line grooves, but the steel wire rope is still wound into a shape with the broken line grooves; after the steel wire rope passes through the 2 nd rope groove sleeve, the steel wire rope arrives at the 2 nd optical sleeve, and the steel wire rope continues to wind along the original direction under the action of the tensile force; after the steel wire rope passes through the 2 nd optical sleeve, the steel wire rope reaches the 1 st rope groove sleeve again; the central line of the steel wire rope is contacted with the steel wire rope wound by the 1 st rope groove sleeve, so that the steel wire rope automatically slides into the adjacent rope groove without the steel wire rope, and the steel wire rope in the 2 nd rope groove sleeve is staggered by a distance of half of the rope groove; a section of wire rope in the shape of a broken line is then formed on the 2 nd optical sleeve. The wire rope is wound neatly from the start of the spool to the end of the spool by rotating in this way.
When the steel wire rope is wound to the tail end of the winding drum, the steel wire rope on the 2 nd rope groove sleeve reaches the inner side edge of the flange, the broken line shape cannot be formed on the 2 nd optical sleeve continuously, the winding can be carried out continuously along the original direction only under the action of tensile force, the boss of the 1 st rope groove sleeve and the wound steel wire rope climb into the rope groove formed by the boss and the wound steel wire rope, and the 1 st turn of the 2 nd layer steel wire rope is formed on the inner side edge of the flange at the tail end of the winding drum; with the rotation of the winding drum, the steel wire rope arrives at the 2 nd rope groove sleeve; however, as mentioned above, the last 1 rope groove of the 2 nd rope groove sleeve is tightly attached to the inner side edge of the flange and is wound with the steel wire rope, the continuously wound steel wire rope is hard to press on the lower layer steel wire rope in a center-to-center manner, and can only slide into the rope groove formed by the last 1 st rope groove on the 2 nd rope groove sleeve and the steel wire rope wound in the 2 nd rope groove in the opposite direction, and a section of steel wire rope in the shape of a broken line with an opposite included angle is formed on the 1 st optical sleeve; similarly, when the steel wire rope arrives at the 1 st rope groove sleeve, the steel wire rope can automatically slide into the rope groove formed by winding the steel wire rope on the 1 st rope groove sleeve in the opposite direction, and a section of steel wire rope in a broken line shape with an opposite included angle is formed on the 2 nd optical sleeve. The wire rope is wound from the end of the spool to the beginning of the spool in order by rotating in this way.
In the winding process, most of the steel wire ropes are laid in the rope grooves of the rope groove sleeve or in the rope grooves formed by the steel wire ropes at the lower layer, and the broken line-shaped steel wire ropes at the light sleeve are guided. The steel wire ropes at the rope groove sleeve can be orderly arranged, and the steel wire ropes overlapped at a certain angle at the light sleeve can be orderly arranged, so that extrusion and friction between the upper layer of steel wire ropes and the lower layer of steel wire ropes are effectively reduced, and the service life of the steel wire ropes is prolonged.
If other diameter steel wire ropes are needed, the corresponding rope groove sleeves are only needed to be replaced.
The invention has the advantages that the winding drum is not provided with the broken line rope groove, so that the processing and the manufacturing are convenient and efficient, the manufacturing cost is greatly reduced, the strength and the precision of the winding drum are improved, the extrusion and the friction of the steel wire rope in the multi-layer winding process are reduced, and the service life of the steel wire rope is prolonged.
