[0002] The ladder is an indispensable tool for people to work at heights. For this reason, the safety of the ladder is particularly important. When using the ladder daily, if you do not pay attention, it is easy to cause safety accidents. If the load is too large, the legs will be broken. In addition, the ladder is not stabilized, the level is tilted, etc., which will cause the user to fall from a high altitude and cause life hazards. There are also some ladders similar to weight alarms on the market, but many people often take risks and still use ladders in the case of alarms. , leading to frequent occurrence of safety accidents

The invention discloses a safe and reliable electric herring-bone ladder. The safe and reliable electric herring-bone ladder comprises a herring-bone ladder frame with two main ladder columns, a fixedpedal, movable pedals, hinges, a first stepping motor and a second stepping motor. Weight switches are installed on bottom feet of the two main ladder columns. The fixed pedal is fixedly installed onthe lower portion between the two main ladder columns. Two groups of hinges are separately connected to the inner side faces of the two main ladder columns. The movable pedals are fixedly arranged between movable cross hinged arms on the two groups of hinges. The first stepping motor and the second stepping motor are installed on the hinges in a connection mode. According to the safe and reliableelectric herring-bone ladder, the pedals of the ladder are designed into a retractable form, horizontal and weight control switches are added and used for controlling the retracting and stretching ofthe pedals, and once the load or inclination of the ladder exceeds the standard, the pedals are not put down, so that users cannot continue to climb higher to avoid the occurrence of safety accidents.
