Signal cable for new mine locomotive transportation monitoring system

technical field

The utility model relates to a structure of a signal cable for a mine locomotive transportation monitoring system, which belongs to the technical field of cables.

Background technique

With the rapid development of underground mineral resource development, mine construction is developing in the direction of deep, complex, long-distance and other harsh conditions. In addition, due to the large mechanical vibration, heavy dust, high humidity, strong corrosion, and strong electromagnetic interference in the mine, etc. Environmental factors and specific problems such as low locomotive track construction standards, poor vehicle operation regularity, limited maintenance costs, more human interference, and operation and maintenance levels far lower than ground railways have promoted the further improvement of the equipment level of the mine locomotive transportation monitoring system. Combined with the computer network , digital communication, intelligent control, sensing, power electronics, electromagnetic compatibility, explosion-proof and other technologies, after the overall optimized design, the adaptability is very strong. After the system is running, it can avoid common rear-end collisions and collisions of underground trains. The transportation efficiency is improved. In order to ensure the normal use and operation of the system, high-performance and high-strength signal cables are required to match it. However, the existing cables that use grounding wires and insulated cores as power lines and signal lines Ordinary cables with a core and an outer sheath cannot meet the requirements of this system.

The purpose of this utility model is to provide a new type of signal cable for mine locomotive transportation monitoring system with large signal transmission capacity and good measurement and control effect to meet the modernization needs of mine locomotive transportation monitoring system.

The purpose of this utility model is achieved in that the signal cable for the novel mine locomotive transportation monitoring system includes a cable core and an outer sheath made of insulated cores, and is characterized in that the cable core is provided with two signal lines, two One power line and one grounding line, the grounding line is set at the center of the cable core, the signal line and the power line are set around the grounding line at a staggered interval, and the cable core is wound with a single-layer PE polyester tape and a double-layer water-blocking cloth tape in sequence , Extruded low-smoke halogen-free cross-linked polyolefin inner sheath, braided galvanized steel wire armor layer, outer sheath extruded on the armor layer.

The signal wire is composed of twisted wire pairs with insulated wire cores braided with tinned copper wire shielding mesh and wound with a single-layer PE polyester tape. The insulated wire core is composed of a heat-resistant layer of polyimide fluorine composite film and an extruded polyethylene insulating layer wrapped sequentially on a tinned stranded copper conductor.

The utility model has the advantages of reasonable and simple structure, easy manufacture and low cost. The cable has the properties of water resistance, moisture resistance, flame retardant, explosion-proof, corrosion resistance, heat resistance, magnetic shock resistance, vibration resistance, and interference resistance. It also has the functions of strong electromagnetic compatibility, large signal transmission capacity, and excellent measurement and control effect. It is suitable for the cables used in the control lines of the CITIC, centralized and closed control lines of the new mine underground locomotive transportation monitoring system.
