Electric repairing ladder

Abstract

The invention discloses an electric repairing ladder. The electric repairing ladder comprises a base; one end of the base is hinged to a base ladder; the other end of the base is hinged to a sleeve; a motor is arranged at the upper part of the base ladder; the motor is matched with a driving gear; the base ladder and the sleeve are provided with thread knobs; the end parts of the thread knobs are in rotary match with a rotary gear head; the base ladder is arranged in a drawing ladder in a sleeved way; the sleeve sleeves a retractable rod; the drawing ladder and the retractable rod are provided with racks; the top end of the drawing ladder is hinged to the top end of the retractable rod through a hinging shaft; the base is provided with a drawing bottom rod; a lateral supporting leg box is arranged at the side part of the base; the lateral supporting leg box is internally hinged to a lateral supporting leg; a thread supporting leg is further arranged at one end of the lateral supporting leg box. The span and height of the electric repairing ladder can be flexibly adjusted, and electric drive can be adopted, so that labor saving and convenience are realized in a utilization process; a manual retracting method can also be used when no electricity exists, so that the electric repairing ladder is wide in applicable range, firm in fixation and high in safety.

Description

technical field [0001] The invention relates to the field of electric power maintenance auxiliary equipment, in particular to an electric power maintenance ladder. Background technique [0002] When performing power maintenance, it is often necessary for staff to carry out high-altitude operations. During high-altitude operations, it is essential to use maintenance ladders. However, the existing maintenance ladders generally have very limited heights and spans, and they will be limited when performing maintenance work. The range of activities of the maintenance personnel, and the fixing of the maintenance ladder is not very reliable. During the maintenance work, the maintenance ladder slips and falls from time to time, which is likely to cause accidents of personal injury. A new maintenance ladder is now needed to solve the problem. The above-mentioned problems ensure that the maintenance work can be carried out smoothly while taking into account the safety of the maintenanc...
