Description

Technical Field

[0001] The present invention relates to the technical field of crane drum devices, in particular to a drum that improves rope laying and prevents rope entanglement. Background Art

[0002] In the hoisting mechanism of a crane device, the rotation of a drum is usually used to drive a wire rope to lift an object. The drum, also called the drum body, and the wire rope are important executing parts in the hoisting mechanism, and the drum is the most important component structure in the hoisting mechanism. Whether the wire rope can be arranged orderly on the circumferential outer wall of the drum or the drum body during the working process without misalignment and skipping directly affects whether the crane can safely and efficiently lift goods. Whether the multi-layer winding of the wire rope on the drum is neat also seriously affects the service life of the wire rope and the use safety of the drum and the crane device.

[0003] For a double-folded wire rope groove drum, the wire rope grooves are divided into two folded line areas or inclined line areas and two straight line areas in one circumference of the drum; the axial displacement of the two folded line areas forms a groove pitch. When the wire rope is wound on the drum, the first layer of wire rope is arranged along the wire rope grooves of the drum, and the second layer of wire rope should be arranged according to the wire rope grooves formed by the first layer of wire rope, that is, the second layer of wire rope should be pressed between two adjacent turns of the first layer of wire rope to form a stable position of the wire rope; similarly, the arrangement of the third, fourth, etc. layers of wire rope also needs to meet the above requirements. The upper and lower layers of the wire rope are parallel to each other in the straight line area of the drum and intersect in the folded line area. When the wire rope climbs from the lower layer to the upper layer, after passing through the first folded line area and the straight line area, it should enter between two adjacent turns of the lower layer of wire rope to lay the rope neatly. In actual working conditions, it often happens that the wire rope does not meet this requirement at this time, but the upper layer of wire rope is directly superimposed on the lower layer of wire rope; when the wire ropes are superimposed, the position of the upper layer of wire rope is unstable, which will cause the wire rope to be arranged unevenly on the drum, that is, there will be a phenomenon of rope entanglement, which seriously affects the winding and use of the wire rope on the drum.

[0004] For example, Chinese patent publication number CN 104340900 A discloses a method for arranging ropes on a drum of a double-fold lifting mechanism with full intervention at the end of a crane. The method specifically discloses a method for arranging ropes on a drum of a double-fold lifting mechanism with full intervention at the end of a crane. The drum rim is installed at both ends of a double-fold cylinder, and a rope retaining platform is arranged at the intersection of the double-fold cylinder and the drum rim; the number of rope arranging layers is N; the drum rim is moved to both ends by a distance of (N-1)*0.5 rope grooves, and the rope retaining platform occupying half of the rope groove is extended to the rim to the width of the entire rope groove, and then the other half of the circle is increased by half of the rope groove width; the first layer of wire rope starts to be wound from one side of the double-fold cylinder, and when it goes around the edge of the other side and climbs into the second layer, the folding line is completed under the action of the rope retaining platform; the winding continues, and the folding line in the return direction is completed under the obstruction of the rope retaining platform with a high rope diameter on the second layer, so that the return order of the wire rope is determined; the back and forth process is repeated until the wire rope is wound. By improving the double-fold line cylinder, the double-fold line arrangement of the wire rope after the second layer is as orderly as the first layer, reducing the phenomenon of rope disorder in the lifting mechanism.

[0005] Another example is the application publication number CN 114590733 A, the disclosed invention name is "A drum rope arrangement device and a crane", which specifically relates to a drum rope arrangement device and a crane. The drum rope arrangement device comprises: a drum, on which a rope groove is arranged around; a steel wire rope, suitable for winding in the rope groove; a clamping ring, sleeved on the outside of the drum, and the clamping ring is suitable for moving along the axis direction of the drum; at least one roller, installed on the clamping ring, the rotation axis of the roller is parallel to the axis of the drum, and the roller is suitable for pressing the steel wire rope into the rope groove when following the movement of the clamping ring. The drum rope-arranging device provided by the present invention has a clamping ring sleeved on the outer side of the drum so that the clamping ring is suitable for moving along the axial direction of the drum, and a roller is arranged on the clamping ring. When the roller follows the movement of the clamping ring, the wire rope is pressed into the rope groove, so that the wire rope is neatly arranged on the drum, preventing the occurrence of tangled ropes and avoiding safety accidents. At the same time, it is ensured that the wire rope is not arranged in a disorderly manner when the drum is working at high speed, thereby extending the service life of the wire rope and reducing the cost of rope replacement.

[0006] It can be seen from the above disclosed winding drum structures that none of them solve the problem of preventing the rope from being disordered and allowing the wire rope to be wound in an orderly manner by improving the structure of the winding drum itself. The winding drum structure is more complicated, and the structure and preparation cost of the winding drum are also increased.

[0007] The characteristics of a double-folded wire rope groove drum are that within each revolution of the drum, approximately 75% - 80% of the wire rope grooves are straight sections or straight zones, and the remaining small part is inclined wire rope grooves or folded zones or inclined zones. When the wire rope is wound in multiple layers, the upper and lower layer wire ropes cross and transition in the inclined wire rope grooves. In the straight section or straight zone of the wire rope groove, the upper layer wire rope completely falls into the wire rope groove formed by two adjacent wire loops of the lower layer wire rope, arranging the upper layer wire rope in the wire rope groove formed by the lower layer wire rope, making the position of the upper layer wire rope stable and arranged in an orderly manner. In this way, the contact between the upper and lower layer wire ropes can be improved, thereby extending the service life of the wire rope.

[0008] For the multi-layer winding of the spiral grooves on the drum, since the winding helix directions of the upper and lower layer wire ropes are opposite, there must be two positions where the upper and lower layer wire ropes cross and transition, and the positions of these cross-transition points on the drum circumference are not completely fixed. Therefore, it is possible to cause the wire ropes to be arranged unevenly.

[0009] Therefore, how to provide a drum device that can improve wire rope arrangement and prevent wire rope entanglement. By using a folded wire rope groove to replace the traditional wire rope arrangement mechanism, and the filling and anti-wire rope entanglement component devices at both ends of the drum used in conjunction with it, etc., effectively preventing the wire rope from being severely squeezed and worn when transitioning from the lower layer to the upper layer, shortening the service life of the wire rope, and ensuring the position of the fixed wire rope when it returns, that is, not fixing the cross-transition position of the upper and lower layer wire ropes at the starting position of the upper layer wire rope, which may cause uneven wire rope arrangement. Summary of the Invention

[0010] The purpose of the present invention is to provide a drum device that can improve wire rope arrangement and prevent wire rope entanglement. There are device components for preventing wire rope entanglement and improving wire rope arrangement on the drum device to solve the technical problems raised in the above background technology. The upper layer wire rope is arranged in the wire rope groove formed by the lower layer wire rope, making the position of the upper layer wire rope stable and arranged in an orderly manner; thereby improving the contact between the upper and lower layer wire ropes and extending the service life of the wire rope.

[0011] To achieve the above object, the present invention provides a drum device for improving rope laying and preventing rope entanglement, which includes a drum body, a first baffle, a second baffle, and a rope inlet.

[0012] In the drum device for improving rope laying and preventing rope entanglement according to the present invention, the anti-drum rope entanglement part includes an inlet end anti-roll rope entanglement unit and a climbing end anti-roll rope entanglement unit. The inlet end anti-roll rope entanglement unit is arranged at a corresponding position on the outer peripheral wall surface of the drum body at the connection between the first baffle and the drum body, and one end of the inlet end anti-roll rope entanglement unit is located at a corresponding position of the rope inlet on the first baffle. The climbing end anti-roll rope entanglement unit is arranged at a corresponding position on the outer peripheral wall surface of the drum body at the connection between the drum body and the second baffle.

[0013] Preferably, both the first improved rope laying panel and the second improved rope laying panel adopt a herringbone inclined panel structure. The first improved rope laying panel is arranged on the inner wall surface of the first baffle corresponding to one folded line area of the drum body, and the second improved rope laying panel is arranged on the inner wall surface of the second baffle corresponding to the other folded line area of the drum body. Moreover, the first improved rope laying panel and the second improved rope laying panel respectively correspond to the two folded line areas on the outer peripheral wall surface of the drum body.

[0014] In the drum device for improving rope laying and preventing rope entanglement, the outer shapes of the first improved rope laying panel and the second improved rope laying panel form a fan-shaped herringbone inclined panel structure. It is controlled that the thickness of the first improved rope laying panel and the second improved rope laying panel with the fan-shaped herringbone inclined panel structure arranged on the inner wall surfaces of the first baffle and the second baffle respectively gradually increases from 0 to 1 / 4 - 1 / 3 of the steel wire rope diameter along the circumferential direction of the drum body, and then gradually decreases to 0. The radial height of the first improved rope laying panel 7 and the second improved rope laying panel corresponds to the layer thickness of the steel wire rope wound on the drum body. The lengths of the first improved rope laying panel and the second improved rope laying panel along the circumferential direction of the drum body respectively correspond to the lengths of the two folded line areas.

[0015] A drum device for improving rope laying and preventing rope entanglement according to the present invention, wherein the anti-rolling and anti-entangling unit at the rope inlet end includes a rope inlet end steel bar and a first guiding steel bar. The rope inlet end steel bar and the first guiding steel bar are fixedly connected to the outer circumferential wall surface of the drum body at the connection between the drum body and the first baffle and the inner wall surface of the first baffle. The rope inlet end steel bar includes an inclined cut end and a rope inlet connection end; the inclined cut end of the rope inlet end steel bar corresponds to the rope inlet on the first baffle, and the other end, the rope inlet connection end of the rope inlet end steel bar, is connected to one end of the first guiding steel bar.

[0016] Preferably, in the present invention, the anti-rolling and anti-entangling unit at the climbing end is arranged at the folded line section position on the outer circumferential wall surface of the drum body at the connection between the drum body and the second baffle on the other side corresponding to the second improved rope laying panel and on the inner wall surface of the second baffle; it includes a climbing end steel bar and a second guiding steel bar. One end of the climbing end steel bar is provided as an arc-shaped groove end, and the other end is a climbing connection end; the climbing end steel bar is fixedly arranged on the outer circumferential wall surface of the drum body at the connection between the drum body and the second baffle and on the inner wall surface of the second baffle; the climbing connection end of the climbing end steel bar is connected to one end of the second guiding steel bar.

[0017] For the drum device for improving rope laying and preventing rope entanglement described above, it is controlled that the axial width of the rope inlet end steel bar gradually decreases from the width of one steel wire rope diameter to one-half to one-third of the steel wire rope diameter between the inclined cut end and the rope inlet connection end; its radial thickness is one steel wire rope diameter or gradually decreases from the diameter of one steel wire rope to three-fourths of the steel wire rope diameter.

[0018] For the drum device for improving rope laying and preventing rope entanglement described above, it is controlled that the axial width of the climbing end steel bar gradually decreases from the width of one steel wire rope diameter to three-fourths to one-half of the steel wire rope diameter between the arc-shaped groove end and the climbing connection end; and its radial thickness gradually increases from 0 to the height distance of one steel wire rope diameter.

[0019] Preferably, it is controlled that the circumferential angles corresponding to the two straight line sections of the drum body along the circumferential direction are 135 - 145° respectively; and the circumferential angles of the two folded line sections along the circumferential direction of the drum body are 35 - 45° respectively.

[0020] A drum device for improving rope laying and preventing rope entanglement disclosed by the present invention has the following beneficial effects by adopting the above device structure. First, an improved rope laying part and a part for preventing the drum from getting entangled are respectively provided on the drum body device. For a slant line segment (hereinafter the same) at the first turn and the last turn on the outer circumferential wall surface of the first layer of the drum body 1, the rope inlet end steel bar 5, the climbing end steel bar 10, and the corresponding first guiding steel bar 6 and second guiding steel bar 9 are respectively provided for filling. That is, the circumferential angle corresponding to the drum body 1 along the circumferential direction or the axial direction is set to 40°, and it corresponds to the slant line segment of the drum rope groove, that is, the circumferential angle of the slant line segments at the first turn and the last turn is 40°, corresponding to another slant line segment of the rope groove on the drum body 1. Its width is made to gradually shrink from half of the rope diameter width to 0, and the thickness is one rope layer height. And it is connected to the first guiding steel bar 6 and the second guiding steel bar 9 in the straight line segment to make it smoother and better realize the transition of the steel wire rope.

[0021] Second, the width of the rope inlet end steel bar of the present invention gradually shrinks from one rope diameter width to half of the rope diameter width along the axial direction, and the thickness is the height of one layer of steel wire rope. In terms of its external shape structure, one end of the rope inlet end steel bar 5 adopts an inclined cut, so as to better fill the gap left after the first layer of steel wire rope enters the drum through the rope inlet groove, preventing the second layer of steel wire rope from being squeezed downward due to the existence of the gap here, resulting in extrusion wear of the steel wire rope. And the surface of the circle formed by the steel wire rope here is uneven and sunken, affecting the arrangement of the subsequent layers of steel wire ropes. Thus, the rope laying effect of the steel wire rope can be greatly improved.

[0022] The present invention is preferably that a climbing end steel bar is provided at the connection between the drum body 1 and the second baffle 3, and the structure of the climbing end steel bar is controlled, as Figure 11 shown, that is, by controlling the width of the climbing end steel bar 10 along the axial direction to gradually shrink from one rope diameter width to half of the rope diameter width, and the thickness along the radial direction to gradually increase from 0 to the height of one layer of steel wire rope, that is, the vertical height from the center of the lower layer of steel wire rope to the center of the upper layer of steel wire rope. And on this basis, an arc groove guide is added, and the axis angle is offset inward. When the first layer of steel wire rope winds to this place, due to the action of the climbing end steel bar 10, the steel wire rope 11 is lifted to the height of the second layer of steel wire rope 11 and accurately falls into the rope groove formed with the first layer of steel wire rope.

[0023] The present invention preferably controls the circumferential angle of the straight line area, that is, the straight line segment on the drum body 1 corresponding to its circumferential direction to be 140°, corresponding to the straight line area of the drum rope groove. Its width is half of the rope diameter width, and the thickness is the height of one layer of steel wire rope. It is an annular surface with equal width and equal thickness, and its function is to make the lifted steel wire rope fall into the groove formed by this ring and the rope loops of the adjacent first layer of steel wire rope. Under the action of the filling steel bars in the above several sections, the steel wire rope can smoothly transition from the first layer to the second layer, and the upper and lower layers of steel wire ropes cross and transition and are fixed in the slant line segment of the rope groove.

[0024] On the other hand, in view of the deficiencies of the double-folded wire rope groove drum or the double-folded wire rope groove drum device in the present invention, that is, when the second layer of wire ropes starts to wind, after the first cross-transition with the first layer of wire ropes, in the straight section of the rope groove corresponding to a circumferential angle of 140°, a gap with a width of half a wire rope diameter will be formed between the second layer of wire ropes and the filling steel bars. And this gap cannot be filled by the steel bars for preventing the drum from getting entangled, such as the inlet-end steel bars 5, the climbing-end steel bars 10, and the guiding steel bars, etc., because the first layer of wire ropes needs to wind here without interference. Similarly, such a gap will also be generated when the second layer transitions to the third layer, and such gaps will be generated during each layer transition. Therefore, the multi-layer wire rope drum is not stable enough in the cross-section. In view of this defect, the present invention respectively adds a first improved wire rope arranging panel 7 and a second improved wire rope arranging panel 8 within a range of a circumferential angle λ of 40° along the circumferential direction of the drum body 1 on the inner side wall panels of the first baffle 2 and the second baffle 3 corresponding to the drum body 1, and their positions correspond to the cross-section of the drum body, that is, corresponding to between the two-folded line areas. Preferably, the height in the axial direction gradually increases from 0 to 1 / 4 of the diameter of a wire rope 11, and then gradually decreases from the height of 1 / 4 of the diameter of a wire rope 11 to 0, that is, in a herringbone shape structure. Preferably, the outer shape is a fan-shaped herringbone inclined panel with both sides closely attached to the walls of the first baffle 2 and the second baffle 3. Due to the functions of the first improved wire rope arranging panel 7 and the second improved wire rope arranging panel 8, when the wire rope 11 winds around the outer side wall of the drum body 1 in the cross-section, it is not easy to fall into the above-mentioned gap, but stably enters the expected rope groove. The subsequent wire ropes will wind in the order of straight-cross-straight-cross. In this way, the problem of easy entanglement of the multi-layer drum device is greatly improved, and the purpose of improving the wire rope arranging effect of the drum and preventing the drum from getting entangled during the wire rope winding process is achieved.

The maximum distance from the highest point to the side wall surfaces of the first baffle 2 and the second baffle 3 is 0.25 times the diameter of the steel wire rope 11, that is, one-fourth of the rope diameter, as Figure 10 shown in the H value in. The maximum value is equal to one-fourth of the diameter of the steel wire rope 11; the first improved rope arranging panel 7 is provided on the inner wall surface of the first baffle 2 corresponding to a folding line area of the winding drum 1, as Figure 8 shown.

The circumferential angle λ of the broken line area along the outer circumferential wall surface of the drum body 1 is preferably controlled at 40°, that is, the circumferential angle λ of the circumference along the axial direction of the drum body 1 is 40°; similarly, the circumferential angle λ of the circumference along the axial direction of another broken line area in this embodiment is also 40°; and the circumferential angles of the two straight line areas along the outer circumferential wall surface of the drum body 1 are preferably 180° - λ, that is, 140°; as Figure 5 , 6 , 8, 11 shown; preferably, the length of the inlet rope end reinforcing bar 5 along the circumferential direction of the drum body 1 is also the length corresponding to the circumferential angle λ of 40°. At the same time, it is controlled that the axial width of the inlet rope end reinforcing bar 5 gradually shrinks from one rope diameter width to one-half of the rope diameter width starting from the inlet rope connection end 502, as Figure 11 shown, that is, the length of the above-mentioned gradually changing part of the inlet rope connection end 502 along the outer circumferential wall surface direction of the drum body 1; and its radial thickness is the distance from the diameter of one steel wire rope 11 to three-fourths of the diameter of the steel wire rope, preferably the diameter distance of one steel wire rope 11; that is, the height along the inner wall surface of the first baffle 2.

[0049] As Figure 4 , 12 shown, this embodiment shows that the climbing end reinforcing bar 10 and the second guiding reinforcing bar 9 are provided on the inner wall surface at the connection between the second baffle 3 and the drum body 1. One end of the climbing end reinforcing bar 10 is set as an arc groove end 1001, and the other end is a climbing connection end 1002; the climbing connection end 1002 of the climbing end reinforcing bar 10 is connected to one end of the second guiding reinforcing bar 9. As Figure 7 shown, on the inner wall surface of the second baffle 3 corresponding to the broken line area on the outer circumference of the drum body 1 at the connection between the second baffle 3 and the drum body 1, a second improved rope laying panel 8 corresponding to the circumferential angle of the broken line area of the drum body 1 is provided; as Figure 12As shown, between the climbing end reinforcing bar strip 10 from the arc groove-shaped end 1001 to the climbing connection end 1002, its width in the axial direction gradually shrinks from the diameter width of one or a steel wire rope 1 to half of the steel wire rope diameter width, that is, half of the rope diameter width; while its thickness in the radial direction gradually increases from 0 to the height of one layer of steel wire rope, that is, the diameter height distance of one steel wire rope 1 or the vertical height distance from the center of the lower layer of steel wire rope 11 to the center of the upper layer of steel wire rope; as Figure 7 shown, it is arranged within the range of a fold line area of the drum body 1 and is symmetrically arranged with the second improved rope arranging panel 8 provided on the second baffle 3.

[0050] As Figure 5 shown, a drum device for improving rope arranging and preventing rope entanglement disclosed by the present invention, a sectional view of the drum body 1. The rope inlet 4 in the figure is arranged at the connection of the first baffle 2 and the outer circumferential wall surface of the drum body 1, and the first improved rope arranging panel 7 is arranged on the inner wall surface of the first baffle 2 on the other side symmetrical to the rope inlet 4 on the first baffle 2. The part of the first guiding reinforcing bar strip 6 arranged on the outer circumferential wall surface of the drum body 1 at the connection with the first baffle 2 corresponds to the first improved panel 7; that is, as Figure 6 shown, in this embodiment, the rope inlet end reinforcing bar strip 5 is arranged at a fold line area position where the drum body 1 is connected to the first baffle 2, and the first improved panel 7 is arranged on the inner wall surface of the first baffle 2 on the other side symmetrical to the rope inlet end reinforcing bar strip 5 and corresponds to another fold line area on the drum body 1. The circumferential angle of the rope inlet end reinforcing bar strip 5 and the first improved panel 7 along the circumferential direction of the drum body 1 is λ, which is also in the range of 40°. Both the first improved panel 7 and the second improved panel 8 adopt a herringbone inclined panel structure, as Figure 10As shown, the distance H value at its highest point is 0.25 times the rope diameter of the wire rope 1, that is, 0.25 times the diameter of the wire rope 11; it is tightly attached to the corresponding positions of the first baffle 2 and the second baffle 3 along the circumferential direction of the drum body 1, and its thickness along the circumferential direction of the drum body 1 gradually increases from 0 to 1 / 4 of the wire rope diameter, that is, 0.25 times the rope diameter, and then gradually decreases to 0. The so-called decrease to 0 means that the distances between the side edges of the first improved panel 7 and the second improved panel 8 in contact with the first baffle 2 and the second baffle 3 respectively are 0, that is, relative to the wall surfaces of the first baffle 2 and the second baffle 3. The present invention adopts the above device structure, and is provided with an improved rope arranging part and a part for preventing the drum from getting entangled with ropes on the drum device; reinforcing bars are filled at both ends of the drum body, so that the wire rope is not easily dropped into the above-mentioned empty space in the crossing section, but stably enters the expected rope groove. The following wire ropes will be wound in the order of straight - crossing - straight - crossing, greatly improving the problem of easy entanglement of ropes in multi-layer drums. Thus, the purpose of improving the rope arranging effect and preventing rope entanglement is achieved, effectively preventing the serious extrusion and wear of the wire rope during work caused by the existing device structure, which shortens the service life of the wire rope, and cannot guarantee the position of the fixed wire rope when it returns, that is, the crossing transition position of the upper and lower wire ropes is not fixed at the starting position of the upper wire rope, which may cause uneven rope arrangement.

[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and all belong to the protection scope of the present invention.
