Slideway-type insulation telescoping work ladder

Abstract

A slideway-type insulation telescoping work ladder is characterized by comprising a basic ladder frame, a basic cross bar, a top connection frame, a positioning pin, a telescopic ladder frame and a telescopic cross bar; the basic ladder frame and the basic cross bar are in vertical fixed connection; the telescopic ladder frame and the telescopic cross bar are in vertical fixed connection; the telescopic ladder frame can be inserted into an elliptical hole in the basic ladder frame, and positioning is achieved by the positioning pin; and two ends of the top connection frame are connected with the top end of the upper-most telescopic ladder frame. Advantages are as follows: the safety of workers can be ensured, a full-time guardian can be liberated, more comprehensive and accurate staff monitoring of the workers can be achieved, work of the workers can be observed without simultaneous holding of a ladder, the work becomes fast and convenient, the workers can rush to a site without simultaneously carrying a working ladder, the workers can go forward with burdens discarded, when the workers arrive at the site, the slideway-type insulation telescoping work ladder can be used only by simple operation, time is saved, and the workload of the workers can be reduced.

Description

technical field [0001] The invention relates to the field of working tools on a transformer platform, in particular to a slideway-type insulated telescopic work ladder. Background technique [0002] At present, for the power distribution profession, in order to beautify the environment, box-type substations or fully insulated landscape transformer sets are gradually replacing the original old-fashioned transformer sets. After the line is transformed and put into the ground, there are many applications. At present, most of the original substations of the lines have been changed to fully insulated landscape substations. If you want to board the control box of the transformer station for operation, you must use a working ladder. The upper end of the working ladder can only be opened on the lower bottom edge of the control box to open the box door. The width of the overlapping position is only 100mm. Safety belt, the seat belt can only be tied to the working ladder, the bottom ...

Problems solved by technology

However, in actual work, due to the complex environment and different terrains, the working ladder can only be straightened by manpower, and there is a danger of falling from a high altitude if there is a little carelessness. Especially in winter, the ground is frozen, and the feet of the working ladder are difficult fixed, the job just got more dangerous
