TECHNICAL FIELD
[0001] The utility model belongs to cable erection technical field, specifically related to a cable erection device for coal mine electrical. BACKGROUND
[0002] In today's coal mining and production field, the stable operation of electrical system is crucial to ensure the safety and efficiency of coal mining operation. As the key carrier of electrical energy transmission in the electrical system, the reasonable erection and stable fixation of cable are indispensable links. In the past coal production practice, there are a series of significant problems and defects in the way and related device of cable erection.
[0003] In the early days, the cable erection in coal mine often relies on simple and primitive means. For example, only through the rope or simple hook to hang the cable randomly on the roadway top or wall, lack of systematic planning and effective fixation measures. This extensive erection method makes the cable in the complex environment of coal mine easily disturbed by various external forces. The ventilation airflow in the roadway, the vibration generated by equipment operation and the frequent activities of personnel and transport vehicles, etc. all can easily cause the cable to sway, twist and even shift. This unstable state of cable not only seriously affects the normal transmission of electrical energy, makes the power supply of electrical equipment intermittent, reduces the operation efficiency and service life of the equipment, but also greatly increases the probability of electrical faults such as short circuit and leakage. Once such failure occurs, not only will it cause the temporary stop of coal production, but also may cause fire, explosion and other extremely dangerous accidents, which poses a serious threat to the life safety of underground personnel.
[0004] In the traditional cable fixation device, there are many deficiencies in structure and function. The design of these devices often lacks sufficient consideration of the actual use scene, and the structure is complex and inconvenient to operate. When facing different specifications, models and materials of cable, its adaptability is very poor, and it cannot be quickly and effectively fixed. Some devices only rely on single clamping method when fixing cable, such as simple bolt fastening or spring extrusion, which is difficult to provide uniform and sufficient clamping force. This leads to the cable gradually loosening due to its own gravity, temperature change and external vibration, etc. during long-term use, thus losing the fixation effect. In addition, the material selection and manufacturing process of traditional fixation device are often not good enough, which can easily be quickly aged and damaged in the harsh environment of coal mine, such as moisture, dust and strong corrosion, further reducing its fixation performance and service life.
[0005] Therefore, we propose a cable erection device for coal mine electrical, which can quickly fix different cables, improve work efficiency, and will not sway, improve safety. CONTENT OF THE UTILITY MODEL
