Abstract
The invention discloses whole set of technology to install attachments in power transmission line construction by using a strain type scaling ladder. The main technology characteristic is that hard replaces soft. The upper end of a scaling ladder (2) is provided with a movable ring (11), (5)s are configured to change various angles and positions, and (6)s position to ensure operation safety. Using the above scheme can make (9)s in various models achieve optimal technology according to design requirement. The scaling ladder is necessary to popularize.
Description
Technical field
The present invention is applied to transmission line annex installation exercise.
Background technology
The aerial ladder used installed by transmission line annex is all generally soft, in practical operation, have very much limitation and weak point.Therefore be necessary that research strain-type aerial ladder makes up " soft " angle with " firmly " and forbidden out of reach defect and deficiency.
Summary of the invention
The object of the invention is to the light section tubular type aerial ladder that factory length can regulate, ladder is equipped with elasticity bolt adjusting angle, a simultaneously attached grapple, grapple is equipped with elasticity bolt equally, so just can according to actual requirement indiscriminately ad. as one wishes operation in actual annex fitting operation.Describe in detail below in conjunction with diagram.
Accompanying drawing explanation
Fig. 1 is the total figure of strain-type aerial ladder and work, and 2 is Changeful type aerial ladder vertical view.5 is grapples, and when grabbing the state that should become 3 shown in dotted line and 4 on conductor 8, fastening 6 keeps firm, convenient optimised process drainage thread 9 being manually adjusted to designing requirement.7 is that porcelain insulator strings insulating effect, avoids electric current to pass into hanging wire cross-arm 10.9 is drainage threads, generally has single, double joint, the Multiple Type such as four and the six roots of sensation according to voltage load.11 is movable links, and tightness adjustable is to ensure hanging ladder fastening security.
Embodiment
Embodiment as shown in drawings, to be positioned the construction eyelet of 10 by 2 during overlap joint drainage thread 9, according to the corresponding adjustment of angle, snatch bar 5 is grabbed on conductor 8 fastening 6 simultaneously, makes 2 stressedly safely can install 9, and by technological operation to the best requirement designed.Such scheme is adopted to achieve the present invention's strain with hard for soft goal of the invention.
Claims (3)
1. a strain-type aerial ladder, is characterized in that: (2) upper end devises (11) adjustment aerial ladder angle flexibly, and out of reach operating radius is supplemented comprehensive convenient operation completely.
2. a strain-type aerial ladder, is characterized in that: work in coordination proper can departing from arbitrarily in (5) and (2), 6 play positioning action again.
3. a strain-type aerial ladder, is characterized in that: (2) firmly replace soft shortcomings and deficiencies, achieves the object of the present invention's strain.
