[0029] As described in the background art, in the prior art, the wear resistance of the trailing cable is mostly poor, and the trailing cable is prone to interference with adjacent structures during use, resulting in wear of the trailing cable and affecting the use.

[0030] To solve this technical problem, this utility model provides a wear-resistant elevator trailing cable.

[0031] Specifically, please refer to Figure 1 , the wear-resistant elevator trailing cable specifically includes:

[0032] A protective layer 2, in which several core wires 1 are arranged, and a protective sleeve 3 is arranged on the outer surface of the protective layer 2, and the protective sleeve 3 is used for protecting the protective layer 2.

[0033] For the wear-resistant elevator trailing cable provided by this utility model, through the provided protective sleeve 3, the protection of the protective layer 2 by the protective sleeve 3 can reduce the interference between the protective layer 2 and adjacent structures during use, thereby reducing the wear of the protective layer 2, improving the wear resistance effect of this application, and improving the safety during use.

[0034] In order to enable those skilled in the art to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0035] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0036] It should be noted that like reference numerals and letters indicate similar items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] Example 1, please refer to Figure 1 , a wear-resistant elevator trailing cable, including a protective layer 2, a plurality of wire cores 1 are arranged inside the protective layer 2, a protective sleeve 3 is arranged on the outer surface of the protective layer 2, and the protective sleeve 3 is used for protecting the protective layer 2, which can reduce the interference between the protective layer 2 and adjacent structures during use, thereby reducing the wear of the protective layer 2, improving the wear-resistant effect of the present application, and improving the safety during use; the protective sleeve 3 is fixedly connected to the outer surface of the protective layer 2.

[0038] At present, the trailing cable mainly uses ordinary polyvinyl chloride insulated sheath cables. The products contain harmful substances to humans such as lead, mercury, cadmium, and hexavalent chromium. The recycling and treatment of the cables will cause secondary pollution to the environment and belong to eliminated products. Such materials have low strength, are not wear-resistant, and are not suitable for high-strength frequent movement and bending occasions; in the present application, the protective sleeve 3 is based on low-smoke, halogen-free, flame-retardant polyolefin materials (PP) and polyether-type polyurethane PUR, and environmentally friendly capsaicin and environmentally friendly bifenthrin extracted from natural plants are added as rodent and termite-proof materials, and then blended and modified with flame retardants such as magnesium hydroxide Mg(OH)2 and aluminum hydroxide Al(OH)3 to form a thermoplastic elastomer, which has low-smoke, halogen-free, flame-retardant environmental protection performance and good weather resistance, has good rodent and termite-proof characteristics, and has low-temperature resistance and flame retardancy. The trailing cable provided by the present application has low-smoke, halogen-free, non-toxic characteristics, does not contain harmful heavy metals such as lead, mercury, cadmium, and hexavalent chromium, is convenient for cable recycling and treatment, and will not cause pollution to the environment; excellent toughness, wear resistance, hydrolysis resistance, and anti-microbial performance, and can maintain the use requirements in cold climates, hydrolysis, sunlight irradiation, or mechanical damage environments;

[0039] The proportion of each component is as follows: low-smoke, halogen-free, flame-retardant polyolefin material (PP): 40-50%; polyether-type polyurethane PUR: 20-30%; environmentally friendly capsaicin: 5-10%; environmentally friendly bifenthrin: 3-5%; magnesium hydroxide Mg(OH)2: 10-15%; aluminum hydroxide Al(OH)3: 5-10%;

[0040] Polyether polyurethane is used to increase the elasticity and wear resistance of the protective cover 3, and also improves the weather resistance and low temperature performance of the protective cover 3; environmentally friendly capsaicin as a natural rodent repellent can effectively repel rodents, environmentally friendly cypermethrin is used to enhance the anti-termite effect, magnesium hydroxide is one of the flame retardants, it absorbs a large amount of heat and releases water vapor when decomposing, which helps to reduce the combustion speed and fire; aluminum hydroxide is also a flame retardant, synergistically working with magnesium hydroxide to further improve the flame retardant performance.

[0042] Further, such as Figure 1 - Figure 2 As shown, the protective sleeve 3 is detachably connected to the outer surface of the protective layer 2, so that the protective sleeve 3 can be replaced after being worn, that is, there is no need to replace the accompanying cable as a whole, thereby reducing the waste of resources, and a fixing mechanism is provided on the protective sleeve 3.

[0043] Furthermore, the fixing mechanism includes a connecting portion connected to the protective sleeve 3 , the connecting portion is connected to a plurality of fixing parts, and the fixing parts cooperate with the connecting portion to fix the protective sleeve 3 on the outer surface of the protective layer 2 .

[0044] Example 3 further optimizes the wear-resistant elevator accompanying cable provided in Example 2. Specifically, Figure 2 As shown, a notch 4 is provided on one side of the protective sleeve 3 near the connection portion. The notch 4 allows the protective sleeve 3 to be moved to increase the gap between the protective sleeve 3 and the protective layer 2, thereby allowing the protective layer 2 to be removed, thereby achieving separation of the protective sleeve 3 from the protective layer 2.

[0045] Further, such as Figure 2 As shown, the connection portion includes two fixing plates 401 fixedly mounted on the protective sleeve 3, and the two fixing plates 401 are respectively located on both sides of the notch 4. The notch 4 can be closed by bringing the two fixing plates 401 close to each other, so that the protective sleeve 3 can be fixed together with the protective layer 2.

[0046] Further, such as Figure 2 As shown, the ends of the two fixing plates 401 away from the protective cover 3 are fixedly connected to the connecting plates 402, and the sides of the two connecting plates 402 close to each other are both arc-shaped. When one or more additional cables are needed, the additional cables can be placed between the two connecting plates 402 and fixed by fixing parts, so that the additional cables can also move with the present application, thereby facilitating the expansion of functions.

[0047] Further, such as Figure 1 - Figure 2As shown in the figure, the fixing member includes two through holes 5, and the fixing member further includes a strap 601 inserted between the two through holes 5. Through the mutual cooperation of the strap 601 and the through holes 5, the two fixing plates 401 can be made to approach each other to close the notch 4.

[0049] Further, as Figure 5 shown, an elastic piece 605 is fixedly connected inside the jack 603. One end of the elastic piece 605 extends out of the jack 603. A number of first engaging teeth 606 are provided on the surface of the elastic piece 605 close to the limiting plate 604. A number of second engaging teeth 607 are provided on one surface of the strap 601. After the strap 601 is inserted into the jack 603, the limitation of the strap 601 can be realized through the mutual engagement of the first engaging teeth 606 and the second engaging teeth 607, and by pressing the elastic piece 605 to separate the first engaging teeth 606 from the second engaging teeth 607, the strap 601 can be pulled to move.
