Abstract
Description
Technical Field
[0001] This invention relates to the field of wire rope production equipment technology, specifically to a basket-type rope twisting equipment with a separate turning system. Background Technology
[0002] When producing strands or wire ropes using basket twisting equipment, the method of turning over the I-beam reel is required to eliminate the twisting torsional stress of the wires or strands, that is, to tighten and break the tension of the wires or strands in order to improve product quality.
[0003] In existing six-strand, eight-strand, and multi-strand basket twisting equipment, most adopt overall turning, that is, the turning coefficient of all strands is the same. The overall turning ratio is controlled by a variable frequency motor through a planetary mechanism. When producing some special products (such as irregularly shaped strand wire ropes), it is often necessary to adjust the turning ratio of a particular strand separately to address the different stresses generated therein, while keeping the turning ratio of other strands at the original set value. This is not feasible. Summary of the Invention
[0004] The purpose of this invention is to provide a separate turning system for a basket-type rope twisting device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a basket-type rope twisting device with a separate turning system, comprising a basket drive motor, a main reduction gearbox, a total turning motor, a basket device, and several coil frames. The output end of the basket drive motor is connected to the upper input end of the main reduction gearbox via a rotating shaft. A total turning reduction gearbox is provided between the output end of the total turning motor and the lower input end of the main reduction gearbox. A total turning gear pair is connected to the output shaft of the total turning reduction gearbox. The basket device is disposed on the output end of the main reduction gearbox and is equidistantly distributed via rotating shafts. Several coil frames are distributed on the basket device, and the coil frames are evenly distributed circumferentially about the rotating shaft of the output end of the main reduction gearbox. A separate turning mechanism is provided at the position of each coil frame on the left end of the basket device, and each coil frame is respectively installed on the rotating shaft of the output end of the corresponding separate turning mechanism.
[0006] Preferably, the individual turning mechanism includes an individual turning motor and an individual turning gearbox. The output end of the individual turning motor is connected to the input end of the individual turning gearbox, and the coil frame is mounted on the output shaft of the individual turning gearbox. Since each coil frame is equipped with an individual turning motor and an individual turning gearbox, the turning ratio of any one stock can be adjusted to be different from that of other stocks without stopping the machine during production.
[0007] Preferably, the individual turning gearbox includes a planetary carrier fixedly mounted on the output shaft of the individual turning primary gearbox. A first planetary gear is mounted on the planetary carrier, and a first central gear and a second central gear are internally meshed within the first planetary gear. The first central gear and the second central gear have a small tooth difference structure. The first central gear is mounted on the output shaft of the individual turning gearbox, and the second central gear is rigidly connected to a second planetary gear. An intermediate gear is located on the side of the second planetary gear near the output shaft of the main gearbox. The intermediate gear is drive-connected to the second planetary gear, and the intermediate gear is drive-connected to the main turning gear pair via a sun gear. Therefore, when a turning ratio for a certain reel frame needs to differ from other reel frames, the main turning motor and the corresponding individual turning motor need to perform a combined action. At this time, the individual turning motor of the reel frame whose turning ratio needs to be adjusted rotates forward or backward, thus intervening in the overall turning process by increasing or decreasing the force to meet product requirements.
[0008] Preferably, the teeth of the first center wheel and the second center wheel differ by one tooth, so that an additional rotation speed is added when the first center wheel outputs, thereby achieving individual turning on the basis of overall turning, realizing single-strand stress adjustment and improving product quality.
[0009] Preferably, a counterweight is connected and installed at the lower end of the planetary carrier.
[0010] Preferably, the reel frame is equipped with I-beam wheels. Multiple reel frames are provided depending on the basket configuration. Multiple reel frames can be flipped simultaneously, or a single reel frame can be flipped individually.
[0011] Preferably, the main gearbox is provided with a main slip ring, and each of the wire reel frames is provided with a secondary slip ring, through which power is supplied to each of the individual turning motors.
[0012] Preferably, both the individual turning motor and the total turning motor are variable frequency motors, so that the total turning ratio and the individual turning ratio are steplessly adjustable. When all individual turning motors are in braking state, all wire spools have the same turning ratio and their common turning ratio is controlled by the total turning motor.
[0013] Preferably, the main reduction gearbox is equipped with three pairs of gears (Z1:Z2, Z3:Z4, Z5:Z6) for deceleration. The rotation of the basket device is driven by the basket drive motor, which drives the main reduction gearbox, and the three pairs of gears in the reduction gearbox reduce the speed and drive the rotation.
[0014] In summary, the beneficial effects of this invention are:
[0015] This invention allows for individual overturning and adjustment of each wire reel frame, enabling adjustments to be made when different stresses are generated in a particular strand. By intervening with stress increases or decreases on the basis of the overall overturning, the overturning ratio of each strand can be adjusted individually, while the overturning ratios of other strands remain at their original settings. This reduces the stress in the produced wire rope and greatly improves its practical performance. Attached Figure Description

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0023] The following is combined Figure 1-2 The present invention will be described in detail below. For ease of description, the directions referred to below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The directions of front, back, left, right, up, and down in the view are consistent. Figure 1 This is a front view of the device of the present invention. Figure 1 The directions shown are consistent with the front-to-back, left-to-right, up-down directions of the device of the present invention when viewed from the front.
[0024] Please see Figure 1-2 This invention provides an embodiment of a basket-type rope twisting device with a separate turning system, comprising a basket drive motor 1, a main reduction gearbox 2, a total turning motor 7, and a basket device 5. The output end of the basket drive motor 1 is connected to the upper input end of the main reduction gearbox 2 via a rotating shaft. A total turning reduction gearbox 8 is provided between the output end of the total turning motor 7 and the lower input end of the main reduction gearbox 2. A total turning gear pair 9 is connected to the output shaft of the total turning reduction gearbox 8. The basket device 5 is disposed on the output end of the main reduction gearbox 2 and is equidistantly distributed via rotating shafts. A plurality of wire reel frames 6 are distributed on the basket device 5. The wire reel frames 6 are evenly distributed circumferentially about the rotating shaft of the output end of the main reduction gearbox 2. A separate turning mechanism is provided at the position of each wire reel frame 6 on the left end of the basket device 5. Each wire reel frame 6 is respectively installed on the rotating shaft of the output end of the corresponding separate turning mechanism.
[0025] It is worth mentioning that, in this embodiment, the separate turning mechanism includes a separate turning motor 3 and a separate turning gearbox 4. The output end of the separate turning motor 3 and the input end of the separate turning gearbox 4 are connected to a separate turning first-stage gearbox 10. The coil frame 6 is mounted on the shaft at the output end of the separate turning gearbox 4.
[0026] Since each reel frame is equipped with an individual turning motor 3 and an individual turning gearbox 4, the turning ratio of any one reel can be adjusted to be different from that of other reels without stopping the machine during production. At the same time, when a certain reel frame needs to have a different turning ratio than other reel frames, the main turning motor 7 and the corresponding individual turning motor 3 need to perform a combined action. At this time, the individual turning motor 3 of the reel frame whose turning ratio needs to be adjusted rotates in the forward or reverse direction, which can intervene by adding or subtracting force on the basis of the main turning to meet the product requirements.
[0027] In another embodiment, the separate turning gearbox 4 includes a planetary carrier 11 fixedly mounted on the output shaft of the separate turning primary gearbox 10. A first planetary gear 12 is mounted on the planetary carrier 11. A first central gear 14 and a second central gear 15 are internally meshed within the first planetary gear 12. The first central gear 14 and the second central gear 15 have a small tooth difference structure. The first central gear 14 is mounted on the output shaft of the separate turning gearbox 4. The second central gear 15 is rigidly connected to a second planetary gear 16. An intermediate gear 18 is provided on the side of the second planetary gear 16 near the output shaft of the main gearbox 2. The intermediate gear 18 is drivenly connected to the second planetary gear 16. The intermediate gear 18 is drivenly connected to the main turning gear pair 9 through a sun gear 17.
[0028] When the turning ratio of the online coil frame 6 is the same, the total turning motor 7 drives the total turning gearbox 8, which transmits the power to the sun gear 17 through the gear pair 9, and then to the second planetary gear 16 through the intermediate gear 18. The second planetary gear 16 is rigidly connected to the second center gear 15. The second center gear 15 transmits the power to the first center gear 14 through the first planetary gear 12. The first center gear 14 directly drives the coil frame 6 to perform the turning action. When the coil frame 6 turns alone, the individual turning motor 3 operates while the overall turning action is in progress. The first planetary gear 12 rotates, and the first center gear 14 and the second center gear 15 have a small tooth difference structure. At this time, an additional speed is added when the first center gear 14 outputs, realizing individual turning on the basis of overall turning, realizing single-strand stress adjustment, and improving product quality.
[0029] It should be noted that, in order to ensure the stability of the first planetary gear transmission, the teeth of the first central gear 14 and the second central gear 15 differ by one tooth.
[0030] In another embodiment, a counterweight 13 is connected and installed at the lower end of the planetary carrier 11 to ensure the transmission stability of the planetary carrier.
[0031] In another embodiment, the reel frame 6 is equipped with I-beam wheels. The reel frame 6 is provided in multiples depending on the basket configuration. Multiple reel frames can perform a flipping action at the same time, or a single reel frame can perform a flipping action individually.
[0032] It should be noted that, since the individual turning motor 3 is mounted on the rotating basket device, in this embodiment, a main slip ring needs to be set on the main reduction gearbox 2, and a branch slip ring needs to be set on each of the wire reel frames 6, so that power can be supplied to each individual turning motor 3 through the slip rings.
[0033] In another embodiment, both the individual turning motor 3 and the total turning motor 7 are variable frequency motors, so that the total turning ratio and the individual turning ratio are both infinitely adjustable.
[0034] In another embodiment, the main reduction gearbox 2 is provided with three pairs of gear pairs (Z1:Z2, Z3:Z4, Z5:Z6) for reduction.
[0035] During actual runtime:
[0036] The rotation of the basket device 5 is driven by the basket drive motor 1, which drives the main reduction gearbox 2. The reduction gearbox is driven to rotate after being reduced by three pairs of gear pairs (Z1:Z2, Z3:Z4, Z5:Z6).
[0037] When multiple coil frames 6 simultaneously perform a flipping motion, i.e., when multiple coil frames 6 flip as a whole, all individual flipping motors 3 are in a braking state, and the motion is completed by the main flipping motor 7: when the main flipping motor 7 rotates forward, the coil frame 6 flips forward; when the main flipping motor 7 rotates in reverse, the coil frame 6 flips backward; and when the main flipping motor 7 is braked, the coil frame 6 is at zero flipping. At zero flipping, the coil frame 6 moves horizontally relative to the ground without rotation.
[0038] At this time, the transmission chain is as follows: the main turning motor 7 drives the main turning gearbox 8, which transmits the power to the sun gear 17 through the gear pair 9, and then to the second planetary gear 16 through the intermediate gear 18. The second planetary gear 16 is rigidly connected to the second center gear 15. The second center gear 15 transmits the power to the first center gear 14 through the first planetary gear 12. The first center gear 14 directly drives the wire reel frame 6 to perform the turning action. At this time, the multiple wire reel frames 6 have the same turning ratio.
[0039] In the overall rolling motion state described above (whether it is a zero roll or a positive or negative roll), by adding the operation of a single rolling motor 3, a single roll can be achieved. There can be one or more single rolls, and the roll ratio of each can be different.
[0040] For example, a single-rolling system with 8 coil frames can achieve up to 8 different rolling ratios. In this case, the single-rolling motor 3 drives the transmission chain as follows: During the overall rolling action, the single-rolling motor 3 operates (it can rotate forward or backward to achieve force application and force breaking), causing the first planetary gear 12 to rotate. The first central gear 14 and the second central gear 15 have a small tooth difference structure, meaning the two gears differ by only one tooth. Therefore, an additional speed is added when the first central gear 14 outputs, achieving a single-rolling on top of the overall rolling action, realizing single-strand stress adjustment, and improving product quality.
[0041] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of the invention. Therefore, the scope of protection of the invention should be determined by the scope defined in the claims.
