Description

Technical Field

[0001] This utility model belongs to the field of elevator cable technology, specifically a fatigue-resistant and tensile-resistant traveling communication optoelectronic composite transmission cable for elevators. Background Technology

[0002] Elevators, long considered signal black holes within buildings, have become a critical point for "signal upgrades." Simultaneously, increasing communication and security demands are driving the intelligent development of the elevator industry, with smart elevators poised for widespread adoption in the future. Furthermore, rapid urban development and the widespread application of video signal transmission have led to an explosive growth in data volume, requiring higher transmission bandwidth. The bandwidth of existing data cables within elevators is insufficient to meet these demands; adopting a fiber optic multi-service distribution system can effectively solve this bandwidth shortage problem. As urban buildings grow taller, the transmission distance supported by existing elevator cables while maintaining high-speed transmission rates is no longer adequate for long-distance communication requirements. On the other hand, the availability of internal fiber optic cables is also crucial; the effectiveness, efficiency, and long-term maintenance of related capabilities of these cables must be guaranteed.

[0003] Meanwhile, the publicly disclosed (announcement) number CN218768861U describes an optoelectronic composite cable that includes a cable sheath, a cable unit, an optical fiber unit, a reinforcing steel wire, and an identification unit. Both the cable unit and the optical fiber unit are housed in the cavity inside the cable sheath. The cable unit is used to transmit power, and the optical fiber unit is used to transmit signals. The reinforcing steel wire is set in the tube wall of the cable sheath, and the identification unit is set in the outer periphery of the tube wall of the cable sheath.

[0004] During use, the aforementioned optoelectronic composite cable is prone to excessive bending due to the low signal attenuation during long-distance transmission in the elevator and the long-term laying under high intensity. This can lead to cable breakage, causing elevator accidents and shortening the replacement frequency of the elevator cable.

[0005] Therefore, a fatigue-resistant and tensile-resistant traveling communication optoelectronic composite transmission cable for elevators is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a fatigue-resistant and tensile-resistant traveling communication optoelectronic composite transmission cable for elevators, which has the advantage of having steel wire reinforcing wires installed inside the cable sheath, thereby enhancing the structural bending protection performance of the cable sheath and cable jacket.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fatigue-resistant and tensile-resistant traveling communication optoelectronic composite transmission cable for elevators, comprising a cable jacket, a twisted-pair shielded optical cable inside the cable jacket, a cable sheath on the outside of the cable jacket, a power cord and an inner ring inside the cable sheath, a steel wire reinforcing wire inserted inside the inner ring, and a tear groove at the middle of the outer side of the cable sheath.

[0008] Preferably, the tear groove is a triangular groove.

[0009] Preferably, the cable sheath and cable jacket are coated with corrosion-resistant polyvinyl chloride.

[0010] Preferably, the top of the cable sheath is provided with a triangular reinforcement component;

[0011] The triangular reinforcement component includes a buckle that is fixed to the cable sheath. A T-shaped frame is inserted into the inside of the buckle. An elastic plate is fixed to the top of the T-shaped frame. A top beam is fixed to the top of the elastic plate. Arc-shaped deformation plates are fixed to both sides of the top beam.

[0012] Preferably, the surface of the elastic plate is provided with an insertion hole, and a fastening pin that penetrates the top beam is inserted into the insertion hole.

[0013] Preferably, the other end of the arc-shaped deformation plate is fixedly provided with a foot support that fits against the cable sheath.

[0014] Preferably, the surface of the elastic plate is provided with grooves, and the elastic plate is made of rubber.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the combination of steel wire reinforcement and twisted-pair shielded optical cable structure, can increase the number of bends of elevator cables during use by adding steel wire reinforcement inside the cable sheath and cable jacket. In the event of strong displacement, it enhances the tensile strength of elevator cables, protects elevator cables, and extends their service life.

[0017] 2. This utility model uses the elastic plate in the triangular reinforcement component in combination with the arc-shaped deformation plate structure to form a triangular structure above the cable sheath, which can stabilize the cable body in a triangular shape, improve the structural strength, and avoid wear on the cable.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The following describes an embodiment of this utility model based on its overall structure.

[0026] like Figures 1 to 4 As shown, this utility model provides a fatigue-resistant and tensile-resistant traveling communication optoelectronic composite transmission cable for elevators, including a cable jacket 5. The inside of the cable jacket 5 is provided with a twisted pair shielded optical cable 4, which can transmit data more stably. The outside of the cable jacket 5 is provided with a cable sheath 1. The inside of the cable sheath 1 is filled with a power cord 3 and an inner ring 6. A steel wire reinforcing wire 2 is inserted into the inside of the inner ring 6. A tear groove 7 is opened at the middle of the outer side of the cable sheath 1. The added tear groove 7 structure facilitates the protection of the internal cable.

[0027] In this embodiment, the tear groove 7 is set as a triangular groove, which facilitates quick tearing.

[0028] The cable sheath 1 and the cable outer jacket 5 are coated with corrosion-resistant polyvinyl chloride to reduce costs.

[0029] The top of the cable jacket 5 is provided with a triangular reinforcement component 8;

[0030] The triangular reinforcement component 8 includes a buckle 81 that is fixed to the cable sheath 5. A T-shaped frame 82 is inserted into the buckle 81. An elastic plate 83 is fixed to the top of the T-shaped frame 82. A top beam 84 is fixed to the top of the elastic plate 83. Arc-shaped deformation plates 86 are fixed to both sides of the top beam 84. The elastic plate 83 and the arc-shaped deformation plates 86 can form a triangular protective structure to support and protect the cable sheath 1.

[0031] The surface of the elastic plate 83 is provided with a hole 88, and a fastening pin 85 that passes through the top beam 84 is inserted into the hole 88. The top beam 84 is fixed above the elastic plate 83 by the fastening pin 85.

[0032] The other end of the arc-shaped deformation plate 86 is fixed with a foot support 87 that fits against the cable sheath 1. The surface of the elastic plate 83 is provided with a toothed groove, and the elastic plate 83 is made of rubber. The added toothed groove structure can provide deformation space.

[0033] Working principle and process of a fatigue-resistant and tensile-resistant traveling communication optoelectronic composite transmission cable for elevators:

[0034] During the production stage, corrosion-resistant polyvinyl chloride materials are prepared in sequence for making cable sheath 1 and cable jacket 5, steel wire reinforcing wire 2, power cord 3, twisted pair shielded optical cable 4 and other cable materials, and the components required for the triangular reinforcement component 8, such as buckle 81, T-shaped frame 82, elastic plate 83, top beam 84, fastening pin 85, arc deformation plate 86, foot support 87, etc., are assembled.

[0035] Twisted-pair shielded optical cable 4 is placed inside the cable jacket 5, and cable sheath 1 is wrapped around the outside of the cable jacket 5. At the same time, power cord 3 and inner ring 6 are filled inside the cable sheath 1, and steel wire reinforcing wire 2 is inserted into the inner ring 6. A triangular tear groove 7 is opened at the middle of the outer side of the cable sheath 1.

[0036] Secure the buckle 81 to the top of the cable sheath 5, insert the T-shaped bracket 82 into the buckle 81, fix the elastic plate 83 to the top of the T-shaped bracket 82, install the top beam 84 on the top of the elastic plate 83, and fix the top beam 84 above the elastic plate 83 by inserting the fastening pin 85 into the insertion hole 88 on the surface of the elastic plate 83 and through the top beam 84. Fix the arc-shaped deformation plate 86 on both sides of the top beam 84, and make the foot support 87 at the other end of the arc-shaped deformation plate 86 fit with the cable sheath 1. Lay the produced cable according to the layout and design requirements of the elevator, ensuring that the cable can move flexibly with the rise and fall of the elevator. Take care to avoid friction or squeezing between the cable and other parts of the elevator to prevent cable damage. Connect the twisted pair shielded optical cable 4 to the elevator's communication equipment to achieve stable data transmission. Connect the power line 3 to the elevator's power system to provide power support for the elevator.

[0037] During elevator operation, the twisted-pair shielded optical cable 4 continuously and stably transmits data, such as elevator operating status information and floor signals. The power line 3 provides power to various elevator devices to ensure normal operation. The steel wire reinforcement 2 withstands the tension of the cable during elevator lifting and lowering, preventing cable breakage. The cable sheath 1 and cable jacket 5 protect the internal cables from external environmental influences, such as dust, moisture, and chemicals. The triangular reinforcement component 8 provides support and protection for the cable, enhancing its stability. The cable is regularly inspected to check for damage or aging of the cable sheath 1 and cable jacket 5, and to check the integrity of the tear groove 7. If any damage is found, it should be repaired promptly. The components of the triangular reinforcement component 8 should be checked for looseness or damage. If any problems are found, they should be tightened or replaced promptly. The connection between the twisted-pair shielded optical cable 4 and the power line 3 should be checked to ensure the stability of data transmission and power supply.

[0038] When a cable malfunctions, such as data transmission interruption or abnormal power supply, the cable sheath 1 can be quickly torn open through the tear groove 7 to inspect and repair the internal cable. If the triangular reinforcement component 8 is damaged, the corresponding parts should be replaced in time to ensure the stability and safety of the cable.
