Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, specifically to a wear-resistant composite cable protection layer for elevators. Background Technology

[0002] The elevator composite cable protection layer is a protective structure wrapped around the elevator composite cable. Its main function is to protect the internal conductors, insulation layer, and other components from external environmental influences and mechanical damage. The material is usually selected based on the application scenario; common materials include polyvinyl chloride (PVC) and neoprene rubber. In some special environments, flame-retardant, oil-resistant, or high / low temperature resistant materials may be used.

[0003] Currently, the protective layers for elevator composite cables still have significant shortcomings in practical applications. Most products have poor air permeability, making it difficult to effectively dissipate the heat generated during cable operation. Long-term heat accumulation can accelerate the aging of internal components. At the same time, insufficient wear resistance is a prominent issue. Under scenarios of frequent elevator starts and stops and continuous friction between the car and guide rails, the protective layer surface is prone to scratches and damage, shortening its service life. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a wear-resistant composite cable protection layer for elevators that has good wear resistance and excellent breathability and heat dissipation.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a wear-resistant composite cable protection layer for elevators, comprising:

[0006] The inner cylinder has several heat dissipation slots evenly distributed on its side wall.

[0007] The middle cylinder is tightly wrapped around the outside of the inner cylinder, and several ventilation holes are evenly distributed on the side wall.

[0008] The outer cylinder, tightly wrapped around the outside of the middle cylinder, is composed of several arc-shaped plates evenly distributed around the middle cylinder. Several connecting strips are provided between adjacent arc-shaped plates, and several wear-resistant protrusions are integrally formed on the outside of the arc-shaped plates.

[0009] Furthermore, the heat dissipation slots are equidistantly distributed in several groups along the length of the inner cylinder, and each group of heat dissipation slots is equidistantly distributed along the circumference of the inner cylinder.

[0010] Furthermore, the ventilation holes are distributed in several groups at equal intervals along the length of the middle cylinder, and are aligned with the heat dissipation slots of each group. Each group of ventilation holes is distributed in several groups at equal intervals along the circumference of the middle cylinder.

[0011] Furthermore, the connecting strips and wear-resistant protrusions are equidistantly distributed along the length of the outer cylinder.

[0012] Furthermore, the inner cylinder is made of synthetic rubber, the middle cylinder is made of nylon woven mesh, and the outer cylinder is made of glass fiber reinforced polyamide.

[0013] Compared with the prior art, the advantages of this utility model are as follows: the outer cylinder is made of glass fiber reinforced polyamide material, and a stable structure is formed by the surrounding distribution of arc-shaped plates. The wear-resistant protrusions on the outer side are uniformly arranged along the length direction, which greatly improves the surface friction resistance. Moreover, the equidistant distribution of the protrusions and connecting strips allows the wear resistance to be uniformly covered on the whole, effectively extending the service life.

[0014] In terms of ventilation and heat dissipation, the heat dissipation slots of the inner cylinder are evenly distributed along the length and circumference to ensure that heat can be evenly dissipated from each section of the cable. The nylon braided mesh of the middle cylinder tightly wraps the inner cylinder, and its ventilation holes are precisely aligned with the heat dissipation slots of the inner cylinder to form an efficient heat dissipation channel. Combined with the flexibility of the synthetic rubber of the inner cylinder and the breathability of the middle cylinder, heat can be quickly dissipated through the multi-layer structure to avoid local overheating from affecting the performance of the cable.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Combined with appendix Figure 1 Appendix Figure 4 A wear-resistant composite cable protection layer for elevators includes: an inner cylinder 1, on which a plurality of heat dissipation slots 2 are evenly provided on the side wall. The heat dissipation slots 2 are evenly distributed in several groups along the length of the inner cylinder 1, and each group of heat dissipation slots 2 is evenly distributed in several groups along the circumference of the inner cylinder 1, which can allow the cable to dissipate heat evenly in all sections and avoid local overheating that affects performance.

[0023] Combined with appendix Figure 5The middle cylinder 3 is tightly wrapped around the outer side of the inner cylinder 1. A number of ventilation holes 4 are evenly provided on the side wall. The ventilation holes 4 are distributed in several groups at equal intervals along the length of the middle cylinder 3 and are aligned with the heat dissipation slots 2 of each group. The ventilation holes 4 are distributed in several groups at equal intervals along the circumference of the middle cylinder 3, which can form an efficient heat dissipation channel and improve the overall heat dissipation efficiency.

[0024] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 The outer cylinder, tightly wrapped around the outer side of the middle cylinder 3, is composed of several arc-shaped plates 5 evenly distributed around the middle cylinder 3. Several connecting strips 6 connect adjacent arc-shaped plates 5. Several wear-resistant protrusions 7 are integrally formed on the outer side of each arc-shaped plate 5. The connecting strips 6 and wear-resistant protrusions 7 are evenly distributed along the length of the outer cylinder, making the outer cylinder structure more stable and ensuring uniform distribution of wear resistance, thus extending its service life.

[0025] The inner cylinder 1 is made of synthetic rubber, the middle cylinder 3 is made of nylon braided mesh, and the outer cylinder is made of glass fiber reinforced polyamide, which takes into account flexibility, breathability and high strength and wear resistance, and is suitable for the elevator cable usage environment.

[0026] The specific implementation of this utility model: During elevator operation, the wear-resistant composite cable protective layer frequently expands, contracts, and bends with the cable. The inner cylinder 1 tightly wraps the cable core. When the elevator's high-speed ascent and descent causes the cable to heat up, the heat dissipation slots 2 on the side wall of the inner cylinder 1 quickly come into play. Multiple sets of slots evenly distributed along the length direction and the circumferentially uniformly arranged structure allow heat to be evenly dissipated from all sections of the cable, avoiding localized heat accumulation. The middle cylinder 3 closely fits the inner cylinder 1 and moves synchronously. Its nylon braided mesh ventilation holes 4 are precisely aligned with the heat dissipation slots 2 of the inner cylinder 1, forming a heat dissipation channel that runs through the inside and outside, accelerating heat dissipation with the airflow generated by the elevator operation. The arc-shaped plate 5 of the outer cylinder flexibly deforms with the bending of the cable, and the connecting strip 6 between adjacent arc-shaped plates 5 ensures that the structure is stable and does not become disjointed. When friction occurs between the elevator and the shaft components during operation, the wear-resistant protrusions 7 on the outer side of the outer cylinder directly contact the force. The evenly distributed protrusions disperse the friction pressure, and the glass fiber reinforced polyamide material effectively resists wear, ensuring the cable's stable performance during long-term high-frequency use.
