Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cable, especially a drag chain cable. BACKGROUND

[0002] The patent document with the Chinese patent application publication number CN118073006A discloses a technical scheme named "a drag chain cable", in which the cable is directly placed between the upper drag chain set and the lower drag chain set, and the cable is directly in contact with the chain links on the upper and lower drag chain sets. Since the chain links on the upper and lower drag chain sets are arranged at intervals, the side edges of the chain links are likely to directly scratch the cable sheath. Moreover, when the drag chain is working, the drag chain often needs to be repeatedly bent, which may cause the cable sheath to be repeatedly scratched by the chain links. Since the cable sheath is mostly made of insulating plastic, the wear resistance of the cable sheath is limited. Therefore, in actual use, the cable sheath is likely to be scratched and cracked in a short time, which not only shortens the service life of the cable, but also reduces the safety of the drag chain cable. Therefore, it is necessary to redesign the structure of the drag chain cable. SUMMARY

[0003] The utility model aims at solving the above problems and deficiencies, and provides a wear-resistant, oil-resistant and flame-retardant drag chain cable. The wear-resistant, oil-resistant and flame-retardant drag chain cable can greatly improve the wear resistance, which can greatly reduce the probability of scratching and cracking of the cable sheath. This not only helps to prolong the service life of the drag chain cable, but also helps to make the drag chain cable have high safety in long-term use.

[0004] The technical scheme of the utility model is implemented as follows:

[0005] A wear-resistant, oil-resistant and flame-retardant drag chain cable, comprising a cable body, characterized in that elastic abutting components are arranged on the upper and lower surfaces of the cable body respectively. The elastic abutting components comprise two elastic abutting strips. One side edge of each elastic abutting strip is connected to the outer wall of the cable body, and the two elastic abutting strips are arranged in an eight-shaped relationship. The distance between the two elastic abutting strips gradually increases in a direction away from the cable body.

[0006] On the basis of the foregoing structure, the utility model provides two specific elastic abutting strips, which are as follows:

[0007] Firstly, the elastic abutting strip is an integrally formed elastic plastic strip structure.

[0008] Furthermore, the elastic abutment strip includes an integrally formed strip portion and a round strip portion. The diameter of the round strip portion is greater than the thickness of the strip portion. One side of the strip portion is connected to the outer wall of the cable body, and the round strip portion is disposed on the other side of the strip portion.

[0009] The second type includes a flexible steel wire strip and an elastic sheet. One side of the elastic sheet is connected to the outer wall of the cable body, and the flexible steel wire strip is disposed on the other side of the elastic sheet.

[0010] Furthermore, the outer wall of the cable body protrudes to form a covering portion that wraps around the elastic sheet.

[0011] Furthermore, the covering portion is a strip-shaped covering portion extending along the length direction of the cable body, and the outer edge of the covering portion is connected to the flexible steel wire strip.

[0012] Furthermore, a limiting member is embedded in the sheath of the cable body, and one side of the elastic sheet is connected to the outer wall of the limiting member.

[0013] Furthermore, the cable body includes a core and an oil-resistant and flame-retardant sheath, the oil-resistant and flame-retardant sheath covering the core, and the elastic abutment strip disposed on the oil-resistant and flame-retardant sheath.

[0014] The beneficial effects of this utility model are as follows: On this wear-resistant, oil-resistant, and flame-retardant drag chain cable, elastic abutment components are respectively provided on the upper and lower surfaces of the cable body. Each elastic abutment component includes two elastic abutment strips, one side of which is connected to the outer wall of the cable body. The two elastic abutment strips are arranged in a V-shape, and the distance between them gradually increases away from the cable body. In this way, the elastic abutment components on the upper and lower surfaces of the cable body can achieve stable and reliable elastic abutment, ensuring stable elastic abutment even during drag chain movement. This prevents the cable body from directly contacting the drag chain links. Furthermore, the elastic abutment greatly improves wear resistance, significantly reducing the likelihood of scratches and cracks on the cable sheath. This not only extends the service life of the drag chain cable but also ensures high safety during long-term use. Attached Figure Description

[0018] As Figure 1 With Figure 2 The utility model discloses a wear -resisting oil -resistant flame -retardant drag chain cable, including cable body 1, for realizing the invention purpose of the utility model, the upper and lower surfaces of cable body 1 are provided with elastic abutment component 2 respectively, elastic abutment component 2 includes two elastic abutment strips 21, and the side of two elastic abutment strips 21 all is connected with the outer wall of cable body 1, and makes two elastic abutment strips 21 be arranged in the splay relationship, still make the interval between two elastic abutment strips 21 gradually increase in the direction away from cable body 1.

[0019] On the wear -resisting oil -resistant flame -retardant drag chain cable, it is on the upper and lower surfaces of cable body 1 respectively provided with elastic abutment component 2, and elastic abutment component 2 includes two elastic abutment strips 21, and the side of two elastic abutment strips 21 all is connected with the outer wall of cable body 1, and makes two elastic abutment strips 21 be arranged in the splay relationship, still make the interval between two elastic abutment strips 21 gradually increase in the direction away from cable body 1. The elastic abutment component 2 of cable body 1 can be stably and reliably abutted on the upper and lower respectively, even when the drag chain moves, can guarantee that elastic abutment is very stable, so that the wear -resisting performance can be greatly improved, and the probability of the cable body 1 wire skin scratch, cracking can be greatly reduced, which not only can prolong the service life of the drag chain cable, but also can make the drag chain cable have high safety under long-term use.

[0020] By two elastic abutment components 2 in the upper and lower direction of cable body 1 respectively elastic abutment corresponding link, which not only can be conducive to accurately limiting the position of cable body 1, but also can slow down the relative sliding and make the sliding amount reduce, so as to play the role of wear -resisting.

[0021] On the basis of the foregoing structure, the utility model gives two specific elastic abutment strips, which are respectively:

[0022] The first kind, as Figure 1 The elastic abutment strip 21 is an integral elastic plastic strip structure. This not only can facilitate manufacturing, but also can guarantee that elastic abutment is very stable and reliable, so as to be conducive to exerting very good wear -resisting performance, and further help to improve the reliability and applicability of the wear -resisting oil -resistant flame -retardant drag chain cable.

[0023] The elastic abutment strip 21 is an abutment strip for delaying the wear of cable body 1, which can greatly reduce the probability of wear of the drag chain cable body, so as to obtain the wear -resisting effect.

[0024] As shown in Figure 1 The elastic abutting strip 21 includes an integrally formed strip portion 211 and a round strip portion 212, the diameter of the round strip portion 212 is greater than the thickness of the strip portion 211, one side edge of the strip portion 211 is connected with the outer wall of the cable body 1, and the round strip portion 212 is arranged on the other side edge of the strip portion 211. This not only helps to stably achieve the elastic lapping effect, but also has good wear resistance, thereby helping to further improve the service performance of the wear-resistant and oil-resistant flame-retardant drag chain cable.

[0025] As shown in Figure 1 When the wire skin of the cable body 1 adopts an insulating plastic skin with elasticity and certain hardness, the strip portion 211 and the round strip portion 212 are in an integrally formed structure with the wire skin of the cable body 1. This not only helps to improve the manufacturing efficiency, but also enables the elastic abutting strip 21 to stably exert the elastic abutting effect.

[0026] Secondly, as shown in Figure 2 The elastic abutting strip 21 includes a flexible steel wire strip 213 and an elastic sheet 214, one side edge of the elastic sheet 214 is connected with the outer wall of the cable body 1, and the flexible steel wire strip 213 is arranged on the other side edge of the elastic sheet 214. The elastic sheet 214 can generate elastic force, and the flexible steel wire strip 213 not only meets the bending requirement, but also improves the wear resistance and tensile resistance, thereby further improving the stability of the elastic abutting and the wear resistance, and further helping to further improve the reliability and applicability of the wear-resistant and oil-resistant flame-retardant drag chain cable.

[0027] As shown in Figure 2 The outer wall of the cable body 1 protrudes to form a cladding portion 11 wrapped around the elastic sheet 214. This can flexibly limit and strengthen the elastic sheet 214, thereby avoiding the situation that the elastic sheet 214 is excessively bent to affect the elasticity, and thereby helping to further improve the reliability of the wear-resistant and oil-resistant flame-retardant drag chain cable.

[0028] As shown in Figure 2 The cladding portion 11 is a strip-shaped cladding portion extending along the length direction of the cable body 1, and the outer side edge of the cladding portion 11 is connected with the flexible steel wire strip 213. This can stably and reliably support and limit the flexible steel wire strip 213, thereby helping the flexible steel wire strip 213 to exert a more stable and reliable abutting effect, and thereby helping to further improve the service performance of the wear-resistant and oil-resistant flame-retardant drag chain cable.

[0029] As shown in Figure 2 The thickness of the cladding portion 11 is less than the diameter of the flexible steel wire strip 213, which can enable the flexible steel wire strip 213 to stably achieve the elastic abutting effect, thereby very well meeting the actual use requirement.

[0030] As Figure 2 shown, the cable body 1 is embedded in the line skin, and one side of the elastic sheet 214 is connected with the outer wall of the limiting piece 12. This can enhance the limiting effect of the elastic sheet 214 through the limiting piece 12, thereby further improving the stability and reliability of the installation and positioning of the elastic abutting strip 21, and further enabling the elastic abutting strip 21 to play a more stable and reliable elastic abutting effect.

[0031] As Figure 2 shown, the limiting piece 12 is a steel ring, and the limiting piece 12 is arranged around the core body of the cable body 1. The elastic sheet 214 is a steel elastic sheet strip, and the two ends of the elastic sheet 214 are respectively welded and fixed on the limiting piece 12 and the flexible steel wire strip 213. The limiting piece 12 and the elastic sheet 214 are both several, and the number of the limiting piece 12 is equal to the number of the elastic sheet 214 on the single elastic abutting strip 21. Each limiting piece 12 and each elastic sheet 214 are arranged side by side along the length direction of the cable body 1, and the position of each elastic sheet 214 on the single elastic abutting strip 21 corresponds to the position of each limiting piece 12 one by one. The covering part 11 covers all the elastic sheets 214 on the single elastic abutting strip 21. This not only meets the normal bending requirement of the wear-resistant and oil-resistant and flame-retardant drag chain cable and avoids bending damage, but also enables each elastic abutting strip 21 to stably play an elastic abutting effect, thereby better meeting the actual use requirement.

[0032] As Figure 1 and Figure 2 shown, the cable body 1 includes a core body 13 and an oil-resistant and flame-retardant sheath 14. The oil-resistant and flame-retardant sheath 14 is covered on the core body 13, and the elastic abutting strip 21 is arranged on the oil-resistant and flame-retardant sheath 14. The use of the oil-resistant and flame-retardant sheath 14 can obtain the effect of oil resistance and flame resistance, thereby facilitating the use in more environments, and further helping to improve the applicable range.

[0033] The oil-resistant and flame-retardant sheath 14 is made of existing oil-resistant and flame-retardant insulating plastic, which can meet the actual manufacturing and use requirements.

[0034] As Figure 3 shown, in actual use, the wear-resistant and oil-resistant and flame-retardant drag chain cable is arranged between the upper and lower chain links 10, and the elastic abutting strips 21 on the upper and lower elastic abutting assemblies 2 are respectively elastically abutted on the upper and lower chain links 10. This not only avoids the direct contact of the cable body 1 with the chain links 10, but also meets the requirements of accurate and stable limiting of the position of the cable body 1, and meets the normal bending requirement of the cable body 1, thereby playing a wear-resistant effect, and further meeting the use requirement. The wear-resistant and oil-resistant and flame-retardant drag chain cable can have very high reliability and applicability.
