Abstract
The utility model belonging to an overhauling facility with electricity in electric operation, relates to a single foot insulating composite hanging ladder which is characterized in that, the upper part of a ladder pipe is the head of the ladder which is made of alloy aluminum. The ladder head takes the shape of a capital letter U shape hook, which is internally provided with a bearing pulley. A securing pulley is fixed onto the ladder head and also is provide with an insulating protecting rope. A ladder step is arranged on the ladder pipe. Two ladder pipes can be connected through a joint of the ladder pipe. The lower part of the ladder pipe is provided with a flexible span, which is provided with a fixed span lock and a clamping hoop. The end part of the ladder pipe is provided with an arrow-shooting protecting device. The ladder pipe adopts an epoxy resin glass silk cloth pipe as the making components. The utility model is a single foot insulating composite hanging ladder which is suitable for various hanging heights of a 220KV busbar. The utility model solves the problems that the working intensity of electric overhauling with electricity staff in electric operation is heavy while with low working efficiency, lifting and landing operations are difficult; moreover, the operation is limited to the operating site. Therefore, the utility model has the advantages of reasonable design, light weight, simple operation, convenient application, safety and reliability.
Description
Technical field
The utility model belongs to electric operating hotline maintenance facility, relates to a kind of unipods insulation combination hanging ladder.
Background technology
In the electric energy transmitting process, carrying out live line working is one of principal security that realizes power supply reliability, and live line working is compared with interruption maintenance, has the power supply reliability of raising, strengthens maintenance scheduling, reduction equipment and advantages such as personal injury and saving construction investment.Live line working results from the twenties in 20th century, and the live line working of China is started in the 1950's, and through the practice of over half a century, theoretical and reality has all obtained great development, and the instrument of live line working has also been gone through the improvement of several generations.When live line working surpassed 9 meters when 220KV bus hanging point height, domestic traditional method was to adopt one group of 6.5 meters high double ladder to combine with 6 meters high hanging ladders, and this way exists: the combination activity duration is long, rises and falls, shifts difficulty, and limited by the operation place.Also have in addition such as methods such as insulated flexible ladder, insulated lift ladder, insulation vertical ladders, very dangerous up and down when the operating personnel works, rope ladder ascend operation security performance is relatively poor, operating personnel's labour intensity big, inefficiency.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, purpose be for the labour intensity that solves the operating personnel who is produced when adopting double ladder and the combined operation of hanging ladder because of 220KV bus hanging point height is different greatly, inefficiency, rise and fall, shift difficulty, and be subjected to problem such as operation place restriction, a kind of unipods insulation combination hanging ladder is provided.
The utility model unipods insulation combination hanging ladder content Description:
The utility model unipods insulation combination hanging ladder; it is characterized in that: the top of terraced pipe is terraced head; the ladder head adopts alloy aluminum to make; take the shape of the letter U and collude shape; bearing pulley is set in colluding; the protection pulley is fixed on the ladder head; on the protection pulley, be provided with the insulation protection rope; on terraced pipe, arrange stile; the ladder pipe is provided with 3～5, and two terraced pipes can connect by terraced pipe joint, in the bottom of terraced pipe monkey wrench are set; back-up wrench lock and clip are set on monkey wrench, anti-archery device are set at the tail end of terraced pipe.
The ladder pipe adopts glass epoxy silk stringing to make.
Anti-archery device by: base joint, bolt, drill rod are formed, in the groove of drill rod insertion base joint, flexibly connect by bolt.
The utility model is the different unipods insulation combination hanging ladder of a kind of 220KV of being applicable to bus hanging point height, solved big, the inefficiency of electric operating hotline maintenance operating personnel labour intensity, rise and fall, shift difficulty, and be subjected to problems such as operation place restriction, have characteristics reasonable in design, in light weight, simple to operate, esy to use, safe and reliable.
