Abstract

The utility model discloses an elevating crawling ladder of an electric pole, which comprises an upper crawling ladder fixed on the electric pole through an upper anchor ear and a lower anchor ear. The elevating crawling ladder is characterized in that two vertical pipes are respectively fixed on outer sides of two vertical rods of the upper crawling ladder; sliding sleeves are respectively sleeved on the vertical pipes; a lower crawling ladder is connected on the outer sides of the vertical pipes through the sliding sleeves; the sliding sleeves are respectively fixed at upper ends of the two vertical rods of the lower crawling ladder; a clamping plate is fixedly connected to a beam in the middle of the lower crawling ladder; and a positioning plate frame is fixedly connected with the lower end of the lower crawling ladder. The elevating crawling ladder has the advantages that the structure is simple, the elevating crawling ladder is convenient to use, when in use, the lower crawling ladder drops down, a user can get to the upper crawling ladder from the lower crawling ladder, the time for rod climbing can be shortened, the work efficiency and the rod climbing safety can be improved, the lower crawling ladder is pushed up to be overlapped with the upper crawling ladder after use, the position of the lower crawling ladder can be fixed through the clamping plate, and the requirement on the distance from the ladder to the ground is satisfied.

Description

Electric pole ascending/decending cat ladder

Technical field

The utility model is particularly related to a kind of electric pole ascending/decending cat ladder.

Background technology

At present the electric pole of 15 meters and 18 meters two kinds of models of distribution line all is equipped with cat ladder, and cat ladder must not be lower than 2 meters to the required distance on ground, and the maintainer need adopt climbers to step on to 2 meters high positions and step on cat ladder again, has increased the bar time of stepping on, and has reduced operating efficiency; The maintainer who has dislikes trouble, and taking directly jumps up catches cat ladder bottom, unsettledly again steps on bar and climb, and has the danger of falling, and is unfavorable for job safety.

Summary of the invention

The technical problem that the utility model will solve provides a kind of can the shortening and steps on the bar time, increases work efficiency and steps on the electric pole ascending/decending cat ladder of bar safety.

The utility model is achieved in that it comprises through upper and lower two anchor ears and is fixed on the last cat ladder on the electric pole; Its special character is: two vertical rod outsides at last cat ladder are fixed with a standpipe respectively; On standpipe, be arranged with sliding sleeve respectively, be connected with cat ladder down in the standpipe outside through sliding sleeve, described sliding sleeve is separately fixed at down two vertical rod upper ends of cat ladder; On the crossbeam at following cat ladder middle part, be connected with clamp, be connected with the location grillage in following cat ladder lower end.

Above-mentioned electric pole ascending/decending cat ladder; Upper end at standpipe is provided with Connection Block through two nut clip; Lower end at standpipe is welded with junction plate, and described standpipe upper and lower end uses bolt to be connected with junction plate with the link of upper and lower two anchor ears and the upper and lower end of last cat ladder through Connection Block respectively.

The utility model has the advantages that: simple in structure, easy to use, will descend cat ladder to fall just during use and can climb up cat ladder along cat ladder down, can shorten the bar time of stepping on, increase work efficiency and step on the bar safety; To descend to push away on the cat ladder overlapping after the use, just can satisfy the required distance of cat ladder descending cat ladder location to ground through clamp with last cat ladder.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the left view of the utility model.

Among the figure: location grillage 1, following cat ladder 2, vertical rod 201, crossbeam 202, junction plate 3, clamp 4, sliding sleeve 5, last cat ladder 6, standpipe 7, Connection Block 8, nut 9, bolt 10, anchor ear 11, link 1101, U-bolt 1102, electric pole 12.

The specific embodiment

As shown in the figure; This electric pole ascending/decending cat ladder comprises through upper and lower two anchor ears 11 and is fixed on the last cat ladder 6 on the electric pole 12; Described anchor ear 11 is to be formed by connecting with U-bolt 1102 the link 1101 that lath is welded; Two vertical rod outsides at last cat ladder 6 are fixed with a standpipe 7 respectively; Upper end at standpipe 7 is folded with Connection Block 8 through two nuts 9, is welded with junction plate 3 in the lower end of standpipe 7, and described standpipe 7 upper and lower ends use bolt 10 to be connected with junction plate 3 with the link 1101 of upper and lower two anchor ears 11 and the upper and lower end of last cat ladder 6 through Connection Block 8 respectively.On standpipe 7, be arranged with sliding sleeve 5 respectively; Be connected with cat ladder 2 down in standpipe 7 outsides through sliding sleeve 5; Described sliding sleeve 5 is welded on down two vertical rod 201 upper ends of cat ladder 2 respectively; On the crossbeam 202 at following cat ladder 2 middle parts, be welded with clamp 4 and be stuck on the crossbeam at cat ladder 6 middle parts, be connected with the location grillage 1 that is formed by the iron plate compacting in the lower end of cat ladder 2 down, location grillage 1 corresponding electric pole 12 1 sides are circular arc.

During use, make clamp 4 break away from the crossbeam of going up cat ladder 6 middle parts, fall down cat ladder 2 then, slide into and be stuck in the lower end of standpipe 7 until the sliding sleeve 5 of cat ladder 2 upper ends down with pushing away on the following cat ladder 2, this moment along under cat ladder 2 just can climb up cat ladder 6.After Awaiting Overhaul work is accomplished, will descend to push away on the cat ladder 2 with last cat ladder 6 overlapping, clamp 4 is snapped into just can be with descending cat ladder 2 to locate on the crossbeam at cat ladder 6 middle parts.
