Because the power line is generally erected or laid in the field, and the surrounding environment of the line changes rapidly, the possibility of being damaged by external force is increased. Therefore, it is necessary to increase the effort of external force prevention and to suppress the occurrence of external force damage accidents by means of civil air defense, technical air defense, and the like. At present, large-scale construction projects such as salt-tolerant high-speed rail, east industrial park, sagao major and the like are being built in a fire-checking place, and large-scale construction vehicles operate near lines, so that serious threat is formed to power lines. The QC group manages and controls according to past accident breaking experience teaching and training, even though measures such as safe bottom-meeting, video monitoring installation, personnel watching and the like are adopted. However, due to the factors of the mixing of field operators, the low safety awareness and the like, the situation of unauthorized hoisting without permission of a power supply department sometimes occurs. In order to limit the rough construction of large construction machines such as cranes and pump trucks and improve the field control level, the potential safety hazards can be thoroughly inhibited and the occurrence of line external breakage is reduced only by taking powerful and effective prevention and control measures.
Height-limiting doors are ubiquitous nowadays, but most of the height-limiting doors are heavy, fixed in a certain place, incapable of moving and incapable of providing economy and selectivity, and the height-limiting doors adopted by the power department are only generally specific to large-scale construction machinery, so that the research on novel movable height-limiting doors is particularly necessary.
