Description

Multifunctional insulating telescopic ladder and use method thereof Technical Field The invention belongs to the technical field of electric power overhaul, and relates to a multifunctional insulating telescopic ladder and a use method thereof. Background In the operation maintenance, equipment overhaul and construction operation of a power system, the insulating ladder is an essential basic tool for guaranteeing the safe ascending operation of workers. The intelligent control system is widely applied to indoor and outdoor complex scenes such as transformer substations, distribution rooms, transmission lines and the like, and is used for assisting personnel in approaching power equipment, checking the lines, replacing parts and the like. The ladder with reliable insulating property, stable structure and convenient use is a primary barrier for preventing personal electric shock and high-altitude falling accidents and guaranteeing life safety of operators. At present, the climbing ladder commonly used in the power industry mainly comprises a herringbone ladder, a straight ladder, a rope ladder, a lifting platform and the like. These conventional ladders are typically made of insulating materials such as fiberglass reinforced plastics to meet basic electrical insulation requirements. However, as the scale of the power network is enlarged, the complexity of the equipment is improved, and the operation environment is diversified, the conventional insulating ladder has gradually revealed various limitations and disadvantages in terms of functionality, safety and intelligence, and is difficult to completely adapt to the operation requirements of modern power with high efficiency, fineness and safety. First, there are significant drawbacks in terms of structural functionality and adaptability. The height and shape of conventional insulating ladders are generally fixed or have only limited, manually operated mechanical telescoping or folding functions. The adjustment process is often less accurate, time consuming and laborious, and the reliability of the locking mechanism depends on the experience of the operator, with the risk of slipping due to the unlocked position. Meanwhile, the traditional ladder has single function and shape, is difficult to quickly and stably switch among various working modes such as a herringbone ladder, a one-shaped ladder and the like, and lacks flexible adaptability to different space layouts and operation tasks. Second, there is a serious loss in active safety protection. The safety of the traditional ladder is greatly dependent on the prior inspection and experience judgment of operators, and belongs to passive protection. The system lacks the sensing and early warning capability of real-time risks in the operation process. For example, it is impossible to monitor in real time whether the weight distribution carried by the ladder body is balanced, whether the tilt angle of the ladder body exceeds a safety threshold value due to an external force, whether there is a slight slip or vibration aggravation on the supporting surface, and other risk symptoms. Once load abrupt change, support instability or environmental abrupt change (such as sudden gusts) occur, the traditional ladder cannot provide any active intervention, accidents often occur instantaneously, the time window reserved for personnel to react is extremely short, and safety redundancy is insufficient. Furthermore, the integration and expansibility are not sufficient. The glass fiber insulation ladder cannot meet the composite requirements of night operation, tool carrying and the like, and the traditional glass fiber insulation ladder is large in weight and easy to age. In view of the foregoing, there is a need in the current power operation field for a novel insulating ladder capable of overcoming the technical bottleneck, so as to substantially improve the safety, efficiency and adaptability of the high-altitude power operation.

In order to achieve the purpose, the invention is realized by adopting the following technical scheme: The invention provides a multifunctional insulating telescopic ladder which comprises a main ladder section and an auxiliary ladder section, wherein one ends of the main ladder section and the auxiliary ladder section are hinged, the main ladder section and the auxiliary ladder section are respectively connected with the telescopic ladder section, the telescopic ladder section can slide along the main ladder section or the auxiliary ladder section, locking devices for fixing the telescopic ladder section are arranged on the main ladder section and the auxiliary ladder section, a multi-mode sensor group and a controlle
