Description

Technical Field

[0001] This utility model relates to the field of wire rope processing technology, specifically to a stranding device for processing high-strength suspension wire ropes. Background Technology

[0002] Lifting wire ropes are mainly used to connect crane hooks to the equipment being lifted. They need to have high strength. In the manufacturing process of lifting wire ropes, several steel wires are usually processed into single-twist wire ropes, and then several single-twist wire ropes are processed into double-twist wire ropes. Only double-twist wire ropes can well meet the strength requirements of lifting wire ropes. Currently, common wire rope stranding equipment can usually only perform single stranding of steel wires or wire ropes. Therefore, when making double-twist wire ropes, the steel wires are unwound, stranded, straightened, and wound up to obtain single-twist wire ropes. The single-twist wire ropes are then unwound, stranded, straightened, and wound up to obtain double-twist wire ropes. The wire rope stranding equipment usually cannot continue to strand several single-twist wire ropes that have just completed the stranding operation to obtain double-twist wire ropes, making the processing efficiency of double-twist wire ropes less than ideal.

[0003] Based on the above, Chinese patent document CN221760297U discloses a wire rope twisting machine, including a base frame, a feeding frame welded to the top of the base frame, a feeding disc inside the feeding frame, a twisting seat movably connected to one side of the feeding disc via a bearing, a twisting frame welded to one end of the twisting seat, a twisting disc fixedly installed on the outer wall of the twisting frame, and a rotating gear ring welded to the outer wall of the twisting disc, a motor mounted on the top of the base frame via bolts, a movable gear connected to the output end of the motor via a key and keyway, a stabilizing frame welded to one side of the top of the base frame, a hydraulic cylinder mounted on the inner wall of the top of the stabilizing frame via bolts, and a connecting piece welded to the bottom end of the hydraulic cylinder; The aforementioned patent document discloses a stranding machine for manufacturing steel wire ropes. This stranding machine uses a motor to drive a movable gear to rotate, which in turn drives the stranding disc and stranding frame to rotate, thus stranding the steel wire rope into a single strand. However, this stranding machine can only perform single stranding of the steel wire rope, such as stranding the steel wire into a single-strand steel wire rope or stranding a single-strand steel wire rope into a double-strand steel wire rope. If double-strand steel wire rope is to be manufactured, the wound single-strand steel wire rope needs to be transferred and installed in another stranding machine for re-stranding. During this process, the disassembly, transfer, and installation of the single-strand steel wire rope takes a lot of time, resulting in low production efficiency of double-strand steel wire rope.

Detailed Implementation

[0016] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0017] A stranding device for processing high-strength suspension wire rope includes a drive disc 1, a main stranding disc 2, a main pressing die 3, a center stranding disc 4, and an outer stranding disc 5. A drive structure 11 for rotating the drive disc 1 is provided on one side. The main stranding disc 2 is fixedly connected to the drive disc 1 and is coaxially arranged. A center pressing die 21 is provided at the axis of the main stranding disc 2. Several outer pressing dies 22 are provided near the edge of the main stranding disc 2. The main pressing die 3 is located on the side of the main stranding disc 2 away from the drive disc 1. The center twisting disc 4 is positioned to match the center pressing die 21. There are several outer twisting discs 5, and the positions of the several outer twisting discs 5 and the several outer pressing dies 22 are matched one by one. The structure of the central twisting disc 4 is the same as that of the outer twisting disc 5. The central twisting disc 4 is provided with a transmission shaft 41 that is movably connected to the drive disc 1. Several wire feeding frames 42 are provided on one side of the central twisting disc 4. Several positioning holes 43 that match the wire feeding frames 42 one by one are passed through the surface of the central twisting disc 4. A transmission structure 6 is provided on one side of the drive disc 1 to enable the central twisting disc 4 and the outer twisting disc 5 to rotate synchronously around the transmission shaft 41.

[0018] This utility model discloses a stranding device for efficiently processing double-twist steel wire ropes. Double-twist steel wire ropes are typically used in high-strength applications such as slings. (Refer to...) Figure 1 , Figure 2 , Figure 3 The twisting device mainly consists of a drive disc 1, a main twisting disc 2, a main pressing die 3, a center twisting disc 4, and an outer twisting disc 5. A fixed base 7 is provided below the drive disc 1. The main pressing die 3 is fixedly connected to the fixed base 7. The fixed base 7 is fixedly connected to the drive structure 11. The output end of the drive structure 11 is provided with a drive shaft 12 fixedly connected to the drive disc 1. The drive shaft 12 is movably connected to the fixed base 7. The drive structure 11 adopts a servo motor. The servo motor realizes mechanical transmission through the drive shaft 12 to make the drive disc 1 rotate. A bracket is provided on the top of the fixed base 7 and movably connected to the drive shaft 12. A bearing is provided between the drive shaft 12 and the bracket to ensure that the drive shaft 12 and the drive disc 1 can rotate stably and smoothly. The drive disc 1 drives the main twisting disc 2, the center twisting disc 4, and the outer twisting disc 5 to rotate synchronously. Simultaneously, the center twisting disc 4 and the outer twisting disc 5 rotate around the drive shaft 41 via the transmission structure 6. The wire feeding brackets 42 on the sides of the center twisting disc 4 and the outer twisting disc 5 are used to mount the wire coils. The wire coils unwind single wires, pass them through the positioning holes 43, and then extend them into the center pressing die 21 or the outer pressing die 22. The center pressing die 21 and the outer pressing die 22 respectively press and shape multiple wires into a single-twist wire rope. After leaving the central pressing die 21 and the outer pressing die 22, the single-twist steel wire rope enters the main pressing die 3. The main pressing die 3 presses and shapes several single-twist steel wire ropes into double-twist steel wire ropes. After the strands of several single-twist steel wire ropes are shaped, they are directly twisted again to form double-twist steel wire ropes. After straightening and winding, there is no need for winding, transfer, or installation between the two twisting operations, which shortens the processing time of double-twist steel wire ropes and helps to improve the processing efficiency of double-twist steel wire ropes. It should be noted that the wire pressing die of this utility model adopts the wire pressing device used in common wire rope stranding equipment to control the size and shape of the wire rope. The cross-sectional size of the working area of ​​the wire pressing die is equal to the final specification of the wire rope. When multiple spiral wires or wire ropes are pulled through, the inner wall of the die hole applies radial pressure to the wires, forcing the wires to adjust the spiral angle and fill the gaps to form a regular spiral structure. The main wire pressing die 3 is provided with a traction device for pulling the final formed wire rope on the side away from the main stranding disc 2. The lay length is controlled by adjusting the ratio of the traction speed of the traction device to the rotation speed of the stranding equipment. The above-mentioned wire pressing die and traction device all adopt common processing equipment in the existing wire processing technology. The use of these processing equipment in this utility model is a conventional application of the existing technology. For those skilled in the art, the working principle of these processing equipment is common knowledge. Therefore, the working principle of the wire pressing die and traction device will not be described in detail.

[0019] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 2 , Figure 3 The transmission structure 6 is provided with a ring-shaped fixed gear 61, which is fixedly connected to the fixed base 7. The outer side of the fixed gear 61 is provided with outer gear teeth, and the end of the transmission shaft 41 of the outer twisting disc 5 is provided with an outer gear 62 that meshes with the outer gear teeth. The fixed gear 61 remains fixed and does not rotate during the processing of the wire rope. Since several external twisting discs 5 are arranged in an array around the axis of the drive disc 1, and several external pressing dies 22 are arranged in an array around the axis of the main twisting disc 2, the external twisting discs 5 will rotate around the drive shaft 12. At this time, the external gear 62 at the end of the drive shaft 41 of the external twisting disc 5 meshes with the outer gear teeth, thereby causing the external twisting disc 5 to rotate around the drive shaft 41. Since several pay-off frames 42 and several positioning holes 43 are arranged in an array around the axis of the central twisting disc 4, the pay-off frames 42 and positioning holes 43 will rotate around the drive shaft 41. The drive shaft 41 is aligned with the entrance of the external pressing die 22. The wire coil installed on the pay-off frame 42 unwinds the wire and then is pressed by the external pressing die 22 and extends in a spiral shape, thereby pressing and shaping several wires into a single twist wire rope by the external pressing die 22. Furthermore, the fixed gear 61 has inner gear teeth on its inner side, and the end of the transmission shaft 41 of the central twisting disc 4 has an internal gear 63; the drive disc 1 is movably connected to a gear shaft 64 at a position off the axis, and both ends of the gear shaft 64 are provided with transmission gears 65, which mesh with the inner gear teeth and the internal gear 63 respectively. During the rotation of the drive disc 1, the gear shaft 64 and the transmission gear 65 will rotate around the drive shaft 12. At this time, the transmission gear 65 at one end of the gear shaft 64 will mesh with the inner gear teeth, so that the gear shaft 64 and the transmission gear 65 will both rotate around the axis of the gear shaft 64. The transmission gear 65 at the other end of the gear shaft 64 will mesh with the inner gear 63, causing the central twisting disc 4 and the transmission shaft 41 to rotate. The rotating central twisting disc 4 will cooperate with the central pressing die 21 in a manner similar to the outer twisting disc 5 to twist the steel wire into a single twist steel wire rope. The single twist steel wire rope formed by the cooperation of the central twisting disc 4 and the central pressing die 21 is placed at the axis of the double twist steel wire rope. Several single twist steel wire ropes formed by the cooperation of the outer twisting disc 5 and the outer pressing die 22 are spirally twisted around the axis of the single twist steel wire rope in the main pressing die 3, and finally a high-strength double twist steel wire rope that can be used as a sling steel wire rope is obtained. It should be noted that, since the central pressing die 21 rotates synchronously around its own axis with the main twisting disc 2, and the central twisting disc 4 also rotates around the same axis, the central twisting disc 4 needs to rotate relative to the central pressing die 21 during the wire rope twisting process. Therefore, it is necessary to adjust the transmission ratio between the inner gear teeth, the transmission gear 65, and the inner gear 63 so that the rotational speed of the central twisting disc 4 is greater than that of the main twisting disc 2. At the same time, since the outer pressing die 22 does not rotate around its own axis, the rotational speed of the central twisting disc 4 relative to the central pressing die 21 is the same as the rotational speed of the outer twisting disc 5 relative to the outer pressing die 22, so that the specifications of all single-twist wire ropes formed by twisting are consistent.

[0020] In summary, this utility model discloses a stranding device for efficiently processing double-twisted wire ropes used as sling wire ropes. This stranding device uses a drive structure 11 to rotate the drive disc 1 and the main stranding disc 2. The outer stranding disc 5 and the center stranding disc 4 unwind the wire. The outer stranding disc 5 and the center stranding disc 4, in conjunction with the transmission structure 6, rotate around their respective axes and, in conjunction with the outer pressure die 22 and the center pressure die 21, respectively, strand the wire into single-twisted wire ropes. The rotating main stranding disc 2, in conjunction with the main pressure die 3, strands several single-twisted wire ropes into double-twisted wire ropes. This utility model can perform two stranding operations on double-twisted wire ropes in a compact manner, shortening the process and time of two stranding operations, thus improving the processing efficiency of double-twisted wire ropes.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
