Combined type elevator for power maintenance

Abstract

The invention discloses a combined type elevator for power maintenance. The combined type elevator comprises foot pads, jacks, supporting bases, a drive device, an oil cylinder, a cross beam, a first guide wheel, a first steel rope, a connection base, a second guide wheel, a third guide wheel, a second steel rope, a second insulation frame, a first insulation frame, an elevating platform, a buffering cushion, a fixed ladder, a first insulation block, a first stay cord, an insulation block and a second stay cord. The combined type elevator is reasonable and simple in structure, low in production cost and convenient to install, when the combined type elevator is used, by means of extending of the oil cylinder, the first steel rope, the second steel rope, the first stay cord and the second stay cord are each in a tensioned state, then, a worker stands into the elevating platform, during ascending and descending, a motor is turned on firstly, a first roller, a second roller, a third roller and a fourth roller are driven to rotate, and therefore it is guaranteed that the first stay cord and the second stay cord are loosened while the first steel rope and the second steel rope are tensioned, and the stability of the elevating platform during working 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.

[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.
