Ladder for power maintenance

Abstract

The invention relates to the field of auxiliary equipment for electricians, in particular to a ladder for power maintenance. The ladder comprises a lower ladder body, an upper ladder body, bolts, a ladder connecting device, a delivery device and foot straps, wherein the upper ladder body and the lower ladder body can be switched between a vertical ladder and a herringbone ladder; the bolts are mounted in the connected position of the lower ladder body and the upper ladder body for fixing the vertical ladder; the ladder connecting device is glidingly mounted at rear parts of the lower ladder body and the upper ladder body and used for stabilizing the herringbone ladder; the delivery device is mounted at front parts of the upper ladder body and the lower ladder body and used for delivering articles for the electrician on the vertical ladder or the herringbone ladder; the foot straps include different types of foot straps capable of being changed to adapt to hard ground or soft ground. The ladder is mainly applied to occasions requiring both the vertical ladder and the herringbone ladder and requiring repeated lifting of tools in the power maintenance process; with the adoption of the ladder, stable and convenient switching between the vertical ladder and the herringbone ladder can be realized, and the articles on the ground can be conveniently transferred to the upper end of the ladder when the ladder is in each of two states.

Description

technical field [0001] The invention relates to the field of electrical auxiliary equipment, in particular to a ladder for electric maintenance. Background technique [0002] At present, there are many types of ladders on the market, and the materials are also different. From the structure, they can be basically classified into two categories, one is straight ladders, and the other is herringbone ladders; Cross bar suitable for climbing, used for climbing; herringbone ladder: a kind of climbing tool used for decoration in the space above the plane (such as the roof), because when it is used, the front and rear ladder bars and the ground form a The isosceles triangle looks like a "herringbone" character, so it is called a "herringbone ladder" vividly; both straight ladders and herringbone ladders are widely used in electrician operations. [0003] And in the power maintenance process of some occasions, the electrician needs to stand on the straight ladder to carry out the wo...

[0003] And in the power maintenance process of some occasions, the electrician needs to stand on the straight ladder to carry out the work, and in some occasions, the electrician needs to stand on the herringbone ladder to carry out the work; At this time, if two kinds of ladders are placed in the construction site, Then cause the waste of resources, if only a kind of ladder is placed at the construction site, then when another kind of ladder is needed, the construction schedule will be delayed because of not preparing this kind of ladder, causing adverse effects; in view of this, the prior art Among them, people have invented a device that can switch between a straight ladder and a ladder. For example, a Chinese patent application number 201410611279.7 is a double ladder used as a straight ladder, which can realize the However, when this kind of ladder is used as a ladder, because there is no connecting rod for limiting the position between the ladders, the ladder is easy to open outward under the action of external force, which brings safety hazards; at the same time, the existing Some of the dual-purpose ladders, although they can be switched between straight ladders and ladder ladders, but their functions are relatively single. When an electrician needs to carry a toolbox for work, he either needs to carry it with his hand or carry the toolbox on his body. Climbing up the ladder; either you need to equip the ladder with an independent hoist; or after you walk to the top of the ladder, your companion on the ground will hand you the tool; in the first way, because the electrician needs to use a portable or Carrying the toolbox on the back of the body not only prevents the electrician from taking larger tools, but also increases the labor intensity of the electrician, and it is easy to distract the attention of the electrician in the process of climbing the ladder, which brings potential safety hazards; in the second method, in addition Equipped with an independent lifting device, resulting in an increase in work costs, and when switching from a ladder to a straight ladder, or from a straight ladder to a ladder, the lifting device needs to be disassembled repeatedly due to changes in the highest point of the ladder , which is more troublesome; the third way is a waste of labor and affects the work of the companions themselves
