Description

Technical Field

[0001] The utility model relates to the technical field of wire rope processing, and specifically relates to a wire rope strand tension control device. Background Technique

[0002] The twisting process of wire ropes usually involves the tight winding of multiple steel wires to achieve the required structure and strength.

[0003] However, this process may cause looseness due to uneven tension of the steel wires. Especially when the nominal diameter and tensile strength of a single wire rope are inconsistent, this problem is more likely to occur. In addition, the existing tensioning mechanisms often cannot effectively adjust the tension of the wire rope during the twisting process, resulting in unstable performance of the twisted wire rope and affecting the use effect of the wire rope. Therefore, a wire rope strand tension control device is proposed for the above problems. Content of the Utility Model

[0004] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique, the utility model proposes a wire rope strand tension control device.

A first abutting seat and a second abutting seat are sequentially installed inside the limiting grooves. Tensioning mechanisms are arranged inside both the first abutting seat and the second abutting seat, and the pushing directions of the two groups of tensioning mechanisms are opposite. An internal fixing frame is fixedly installed inside the rotating cylinder, and a driving mechanism is arranged on the internal fixing frame. When the wire rope is being twisted, the wire rope is pushed inward through the tensioning mechanism on the first abutting seat, and the wire rope is pushed outward through the tensioning mechanism on the second abutting seat, thereby realizing the tensioning of the wire rope to facilitate its subsequent twisting.

[0006] Preferably, the tensioning mechanism includes cross through grooves opened inside both the first abutting seat and the second abutting seat. Spring telescopic rods are symmetrically installed inside the cross through grooves. A receiving seat is fixedly installed at the end of the spring telescopic rods. A limiting block is fixedly installed on the receiving seat. A holding roller is rotatably arranged on the receiving seat. When a certain wire rope is too loose during the twisting process of the wire rope, the wire rope can be restored to a tensioned state by the abutment of the two groups of tensioning mechanisms on one of the wire ropes.

[0007] Preferably, the driving mechanism includes a motor fixedly connected to the internal fixing frame, and a motor loading sleeve is sleeved outside the motor. The motor loading sleeve is used to load the motor.

[0008] Preferably, an external fixing frame is fixedly installed on the outer side of the motor loading sleeve, and a loading seat is fixedly installed on the external fixing frame. During the wire rope twisting process, the external fixing frame can also prevent interference with the advancement of the wire rope.

[0009] Preferably, a guiding cylinder is fixedly installed at one end of the rotating cylinder away from the loading seat. A loading groove is formed on the guiding cylinder, and a plurality of guiding rings are fixedly arranged on one side of the loading groove away from the rotating cylinder, which can guide the twisting end of the wire rope to facilitate the wire rope twisting.

[0010] Preferably, a plurality of guiding seats are fixedly arranged on the outer side of the rotating cylinder close to the loading seat, and guiding rollers are rotatably arranged on the guiding seats, so that the device guides the wire rope during the process of the wire rope entering the device, facilitating subsequent twisting work.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. Through the tensioning mechanism on the first abutting seat, during the wire rope twisting, the wire rope is pushed inward, and through the tensioning mechanism on the second abutting seat, during the wire rope twisting, the wire rope is pushed outward, thereby realizing the tensioning of the wire rope to facilitate subsequent twisting. When a certain wire rope is too loose during the wire rope twisting process, through the abutment of the two groups of tensioning mechanisms on the wire rope, the loose wire rope can be restored to a tensioned state, facilitating subsequent twisting, helping to improve the twisting effect of the wire rope, and ensuring its application effect after production.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The following gives specific embodiments.

[0021] Please refer to Figures 1-4 As shown, a wire rope stranding strand tension control device includes a rotary drum 1. A plurality of limiting grooves 12 are provided on the rotary drum 1. A first abutting seat 13 and a second abutting seat 14 are sequentially installed inside the limiting groove 12. Tensioning mechanisms are provided inside both the first abutting seat 13 and the second abutting seat 14. The pushing directions of the two groups of tensioning mechanisms are opposite. An internal fixing frame 5 is fixedly installed inside the rotary drum 1, and a driving mechanism is provided on the internal fixing frame 5;

[0022] During operation, the steel wire is passed through the two groups of tensioning mechanisms. Through the tensioning mechanism on the first abutting seat 13, when the wire rope is stranded, the wire rope is pushed inward. Through the tensioning mechanism on the second abutting seat 14, when the wire rope is stranded, the wire rope is pushed outward, thereby realizing the tensioning of the wire rope for its subsequent stranding. When a certain wire rope is too loose during the stranding process of the wire rope, through the abutment of the two groups of tensioning mechanisms on the wire rope, the loose wire rope can be restored to a tensioned state, which is convenient for subsequent stranding and helps to improve the stranding effect of the wire rope;

[0023] The internal fixing frame 5 is used to load the drive to realize the rotation of the rotary drum 1 driven by the driving mechanism.

[0024] Further, as Figure 1 and Figure 4 shown, the tensioning mechanism includes cross through grooves 15 opened inside both the first abutting seat 13 and the second abutting seat 14. Spring telescopic rods 16 are symmetrically installed inside the cross through grooves 15. The ends of the spring telescopic rods 16 are fixedly installed with bearing seats 17. Limiting blocks 18 are fixedly installed on the bearing seats 17. Abutting rollers 19 are rotatably arranged on the bearing seats 17;

[0025] During operation, the steel wire is passed through two sets of holding rollers 19. Through the holding rollers 19 on the first holding seat 13, when the wire rope is being twisted, the wire rope is pushed inward. Specifically, the spring telescopic rod 16 continuously holds the receiving seat 17, the receiving seat 17 continuously holds the holding rollers 19, and the holding rollers 19 continuously hold the wire rope inward. Through the tensioning mechanism on the second holding seat 14, when the wire rope is being twisted, the wire rope is pushed outward, and its pushing process is the same as that of the holding rollers 19 on the first holding seat 13. The opposite pushing of the two sets of holding rollers 19 realizes the tensioning of the wire rope, which facilitates its subsequent twisting. When a certain wire rope becomes too loose during the twisting process of the wire rope, the tensioning of the wire rope by the two sets of tensioning mechanisms on one of the wire ropes can make the loose wire rope return to the tensioned state.

[0026] Furthermore, as Figure 2 and Figure 3 shown, the driving mechanism includes a motor 6 fixedly connected to the internal fixing frame 5, and a motor loading sleeve 7 is sleeved outside the motor 6;

[0027] During operation, the motor 6 drives the internal fixing frame 5 to rotate, the internal fixing frame 5 drives the rotating cylinder 1 to rotate, and the twisting of the wire rope is realized through the rotation of the rotating cylinder 1. The motor loading sleeve 7 is used to load the motor 6.

[0028] Furthermore, as Figure 3 shown, an external fixing frame 8 is fixedly installed outside the motor loading sleeve 7, and a loading seat 9 is fixedly installed on the external fixing frame 8;

[0029] During operation, the external fixing frame 8 is used to load the motor loading sleeve 7, and the external fixing frame 8 is fixed through the loading seat 9, so that when the rotating cylinder 1 rotates to twist the wire rope, the motor 6 will not rotate with it. The external fixing frame 8 can also prevent interference with the advancement of the wire rope during the twisting process of the wire rope.

[0030] Furthermore, as Figure 1 shown, a guiding cylinder 2 is fixedly installed at one end of the rotating cylinder 1 away from the loading seat 9. A loading groove 3 is formed on the guiding cylinder 2, and a plurality of guiding rings 4 are fixedly arranged on the side of the loading groove 3 away from the rotating cylinder 1;

[0031] During operation, during the twisting process of the wire rope, the guiding rings 4 can guide the twisting end of the wire rope to facilitate the twisting of the wire rope.

[0032] Furthermore, as Figure 1 shown, a plurality of guiding seats 10 are fixedly arranged on the outside of the rotating cylinder 1 near the loading seat 9, and guiding rollers 11 are rotatably arranged on the guiding seats 10;

[0033] During operation, the guiding seat 10 is used to load the guiding roller 11. The guiding roller 11 is in contact with the wire rope during the wire rope stranding process, so that the device guides the wire rope during the process of the wire rope entering the device, facilitating the subsequent stranding work.

[0034] In summary, through the tensioning mechanism on the first abutting seat 13, the wire rope is pushed inward during the wire rope stranding process. Through the tensioning mechanism on the second abutting seat 14, the wire rope is pushed outward during the wire rope stranding process, thereby realizing the tensioning of the wire rope to facilitate its subsequent stranding. When a certain wire rope becomes too loose during the stranding process of the wire rope, the two groups of tensioning mechanisms abut against the wire rope, enabling the loose wire rope to return to the tensioned state, thus facilitating the subsequent stranding, helping to improve the stranding effect of the wire rope, and ensuring its application effect after production.
