Combined electric power maintaining lifting ladder

Abstract

The invention discloses a combined electric power maintaining lifting ladder. The combined electric power maintaining lifting ladder comprises foot pads, jacks, a supporting base, a drive device, an oil cylinder, a beam, a first guide wheel, a first steel wire rope, a connecting base, a second guide wheel, a third guide wheel, a second steel wire rope, a second insulation frame, a first insulationframe, a man loading platform, a buffering pad, a fixing ladder, a first insulation block, a first pull rope, an insulation block and a second pull rope. The combined electric power maintaining lifting ladder is reasonable and simple in structure, low in production cost and convenient to install. During usage, through stretching of the oil cylinder, the first steel wire rope, the second steel wire rope, the first pull rope and the second pull rope are in a tensioned state, and then, a worker stands in the man loading platform; and during lifting, a motor is started firstly, a first roller, asecond roller, a third roller and a fourth roller are driven to rotate, accordingly, it is guaranteed that the first pull rope and the second pull rope are loosened when the first steel wire rope andthe second steel wire rope are tightened, and work stability of the man loading platform is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of electric power maintenance, in particular to a combined lift for electric power maintenance. Background technique: [0002] In electric power maintenance, a climbing ladder is often needed. The ladder supports the electric power maintenance personnel and overhauls the electrical equipment at a higher position. When the maintenance personnel perform maintenance operations, the maintenance personnel generally carry different maintenance tools. For For some tools with small volume and weight, the operator can put the tool in the tool bag. When using it, he only needs to take the tool out from the tool bag. For tools with large volume and weight, the maintenance personnel cannot put the tool The tool is carried around, and the tool can only be placed on the ground. The maintenance personnel need to get off the ladder and select the tool to continue the power maintenance operation, or the staff on the ground ...

[0002] In electric power maintenance, a climbing ladder is often needed. The ladder supports the electric power maintenance personnel and overhauls the electrical equipment at a higher position. When the maintenance personnel perform maintenance operations, the maintenance personnel generally carry different maintenance tools. For For some tools with small volume and weight, the operator can put the tool in the tool bag. When using it, he only needs to take the tool out from the tool bag. For tools with large volume and weight, the maintenance personnel cannot put the tool The tool is carried around, and the tool can only be placed on the ground. The maintenance personnel need to get off the ladder and select the tool to continue the power maintenance operation, or the staff on the ground need to pass the tool to the maintenance staff on the ladder. In addition, the existing elevators are time-consuming and laborious when going up and down, and it is difficult to meet the needs of maintenance personnel.
