Multifunctional maintenance and overhaul tool ladder for electrical equipment

Abstract

The invention discloses a multifunctional maintenance and overhaul tool ladder for electrical equipment. The ladder comprises two ladder rods which are symmetrical left and right, cross rods are connected between the ladder rods, and each ladder rod is divided into a bottom section, a middle section and a top section which are respectively hinged through a pin shaft I and a pin shaft II; two pairsof casters are connected below the bottom sections, a detachable base plate is arranged above a cross rod on the top sections, the end part of the top section is fixedly connected with a handle sleeve, the sleeve is in threaded connection with a handle, the side edge of the top section is symmetrically connected with supporting rods I through bolts I, and the side edge of the bottom section is symmetrically connected with supporting rods II through bolts II. A foldable structure is adopted, so that the risk that a traditional insulating ladder is too long to touch electrified equipment is eliminated; the user is very convenient; the two universal wheels and the two directional wheels are arranged, so that a user can carry out dragging operation conveniently; the ladder has a trolley function, and two hooks at the top end of the ladder are changed into handles when the ladder is used as the trolley; and the maintenance platform function is achieved, and maintenance is more convenient.

Description

technical field [0001] The invention relates to a ladder, in particular to a multifunctional maintenance tool ladder for electrical equipment, belonging to the technical field of electrical equipment maintenance. Background technique [0002] With the popularization of rural electricity in our country, as well as the increase of urban and industrial electricity consumption, the construction of various electrical equipment, especially the construction of 220kV high-voltage electrical equipment is also becoming more and more common. However, with the continuous expansion of power transmission scale, the potential safety hazards in the construction process of high-voltage electrical equipment have become more and more prominent. [0003] Maintenance ladder is an important tool for high-altitude operation of high-voltage electrical equipment, and it is the most direct tool for construction personnel to reach the construction work surface. However, the existing maintenance ladder...

However, with the continuous expansion of power transmission scale, potential safety hazards in the construction process of high-voltage electrical equipment have become more and more prominent

[0003] Maintenance ladder is an important tool for high-altitude operation of high-voltage electrical equipment, and it is the most direct tool for construction personnel to reach the construction work surface. However, the existing maintenance ladder has the problem of inconvenient use. Take the electrical field as an example. The application of insulating ladders in substations requires two people to carry them, and there is a risk of touching live equipment. In addition, the existing maintenance ladders are made of all metal, so the quality and cost are high, and they are not suitable for remote areas. It is practical in mountainous areas and rural areas, and at the same time greatly increases the workload of construction personnel for high-voltage electrical equipment
