Abstract
The utility model provides an ideal combined ladder for climbing up and down an electric transmission line steel tube tower for the technical field of electric power circuit maintenance. The combined ladder for climbing up and down the electric transmission line steel tube tower is provided with a hook and a stand column, and a pedal is arranged on the stand column. The combined ladder for climbing up and down the electric transmission line steel tube tower is characterized in that the hook and the stand column are in threaded connection, and a tension device is arranged on the lower end of the stand column. Compared with the prior art, the combined ladder for climbing up and down the electric transmission line steel tube tower has the advantages of being light in weight, easy to assemble, convenient to carry and use, effective in solving the problem of wastes of manpower resources and the like.
Description
Technical field
The utility model belongs to the Electric Power Line Overhaul equipment technical field, is specifically related to up and down combination ladder of a kind of steel tube tower in electric transmission line.
Prior art
Existing transmission line of electricity adopts steel tube tower in a large number in the city, the steel tube tower cat ladder apart from ground level between 3 meters-4 meters, when needs are stepped on steel tube tower and are carried out service work, need to use long 4 meters ladder, common ladder is because longer, and small-sized maintenance vehicle can not load, and needs to use high capacity waggon, personnel need two people to lift ladder, and working, it comes very inconvenient.Therefore prior art exists use.Carry inconvenience, time-consuming, waste in a large number the deficiencies such as resource.
The utility model content
The purpose of this utility model is up and down combination ladder of a kind of steel tube tower in electric transmission line of design, in order to solve deficiency of the prior art.
For reaching above-mentioned purpose, the main technical schemes that the utility model adopts is: this steel tube tower in electric transmission line is combination ladder up and down, has hook and column, and column is provided with pedal, it is characterized in that: described hook is threaded with column, and the lower end of described column is provided with take-up device.
Described column is a plurality of, between each column by being threaded.
Described take-up device is threaded with column, and the hook that described take-up device has support, be positioned at capstan winch on the support, be wrapped in the wire rope on the capstan winch and be positioned at the wire rope end consists of.
Described pedal adopts accordion structure.
The utility model is that power circuit is carried installation. the service technique field provides up and down combination ladder of a kind of desirable steel tube tower in electric transmission line, this kind combination ladder is owing to being provided with removable single column, can many single column combinations be reached the height that needs by the screw thread of single post end during use, and single column can singlely carry when carrying, because what pedal adopted is folding, be attached on single column pedal is folding when carrying, can be carried by a people.Compared with prior art, have lightweight, be easy to the combination, carry. easy to use, efficiently solve the advantages such as waste of human resource.
Description of drawings
Reach by reference to the accompanying drawings example and further specify specific structural features of the present utility model.
Fig. 1 is the utility model general assembly structural representation.
Fig. 2 is the structural representation of single column.
The specific embodiment
Referring to Fig. 1,2, this steel tube tower in electric transmission line is combination ladder up and down, has hook 1 and column 4, and column 4 is provided with pedal 3, and the end of described hook 1 and column 4 is provided with screw thread 11, will link up with 1 end that is fixedly connected on column 4 by threaded tube 2.The length of described column is 1.2 meters, can be a plurality of, by being threaded, according to the height that will climb, selects the joint number of column between each column.Described pedal adopts accordion structure.The lower end of described column is by threaded sleeve 5 connection tensioners 6.The hook 9 that described take-up device has support, be positioned at capstan winch 10 on the support, be wrapped in the wire rope 8 on the capstan winch and be positioned at wire rope 8 ends consists of, capstan winch 10 is connected with ratchet 7, wire rope can be strained by ratchet 7 during use, thereby with the lower end fixation of combination ladder, ensure the safety that combination ladder uses.
