Abstract
The utility model belongs to special overhauling tools for a power transmission line and is used for being suspended at a bundled conductor when people climb to a vertically-arranged double-bundled conductor from the ground. Provided is an adjustable rope ladder head of a transmission line. The adjustable rope ladder head comprises a ladder rack, the upper end of each side of ladder rods of the ladder rack is provided with an upper pulley type hook and a lower pulley type hook at intervals in the vertical direction, a movable two-body connecting structure capable of adjusting the length is adopted by the ladder rods between the upper pulley type hooks and the lower pulley type hooks, and the adjustment of the distance between the upper pulley type hooks and the lower pulley type hooks is realized so that the distance between hanging conducting wires is satisfied. The adjustable rope ladder head can be applicable to a vertically-arranged double-bundled conductor line with different conducting wire spacing and can also be applicable to a single-conductor line if an upper hanging point pulley can be dismounted, the universality is achieved, the usage is facilitated, equipped tools are reduced, and the cost is lowered.
Description
Technical field
The utility model belongs to transmission line Special maintenance tool, hangs on bundle conductor when climb to vertical arrangement double bundle conductor from ground.
Background technology
In the prior art, supplying electrical domain, rope ladder head is to be mainly used in connecting rope ladder and to hang on a kind of convenient tool of carrying out live line working on wire.Generally include a ladder rectangular frame, be arranged on ladder at least two of framework upper pulley-type hook side by side.Pulley-type hook is a crotch, between crotch shank, is overlapped with pulley, and pulley wheel face is articulated on wire, realizes along wire slippage.The lower end of framework is welded with the link being connected with rope ladder, and a ladder framework adopts aluminum alloy materials, the good stability of rope ladder head, and coefficient of safety is very high, and maintainer's work high above the ground becomes relaxation and happiness (as ZL200920250181.8 patent documentation has report).Vertical arrangement double bundle conductor rope ladder head is stationary structure, and the spacing of the double bundle conductor of the transmission line vertical arrangement of domestic operation is not same distance, this just requires maintenance department to be equipped with many cover software heads, if circuit situation is unfamiliar with and also will be with many sets of plan, this makes former ladder head can not realize a set of ladder multiple use, do not possess versatility, increase cost, affect operating efficiency.
Utility model content
The purpose of this utility model is the spacing difference for the upper and lower hanging point Slip Hook of vertical arrangement double bundle conductor rope ladder head, and providing a kind of can adapt to the adjustable rope ladder head of power transmission line general on the wire of various different spacing by spacing.
Technical solution of the present utility model is: the adjustable rope ladder head of power transmission line, comprise ladder, and every side ladder bar upper end of ladder is between the upper and lower every being placed with upper and lower pulley-type hook.Terraced bar employing activity adjustable-length two attachment structures between upper and lower pulley-type hook, realize the distance of adjusting between upper and lower pulley-type hook, to meet the distance articulating between wire.
In such scheme, the spaced multiple horizontal perforation of arranging between the terraced bar of two attachment structures, is bolted between horizontal perforation.Specifically: between the terraced bar of two body structures, adopt and be abutted against or peg graft.For abutment structure, one section of terraced bar that top sheave formula hook connects downwards, terraced bar lower end connects one section of solid square bar, and square bar is along upper and lower spaced multiple horizontal perforations; The corresponding wheeled hook upper end that glides is fixedly connected with the solid square beam that leans out a section, and solid square beam leans out two horizontal perforations that Duan Shangyou arranges up and down.
The upper hanging point Slip Hook of former stationary type vertical being arranged to double bundle conductor rope ladder head should be adjustable Split type bolt connected mode, and bolt connecting portion adopts open grain structure, to realize the object that regulates length.
The utility model has the advantages that: can on the vertical arrangement twin bundled lines of different conductor spacing, use, also upper hanging point pulley can be removed, on single conductor circuit, use, realize versatility, easy to use, minimizing instrument is equipped with, cost-saving.
Below in conjunction with accompanying drawing, execution mode of the present utility model is described in further detail.Above or following description, be embodiment of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model.
Brief description of the drawings

Embodiment
Referring to Fig. 1-6, parts title is as follows: ladder 1, terraced bar 2, top sheave formula hook 3, the wheeled hook 4 that glides, horizontal perforation 5, bolt 6, solid square bar 7, solid square beam 8,9, one sections of terraced bars 10 of the section of leaning out, ladder crossbeam 11.
Referring to Fig. 1-6, the adjustable rope ladder head of a kind of power transmission line, comprises ladder 1(entirety), be one in ladder crossbeam 11(figure, can have multiple).Every side ladder bar 2 upper ends of ladder 1 between the upper and lower every being placed with upper and lower pulley-type hook 3,4(is the upper and lower hanging point being connected with wire).Terraced bar 2 employing activity adjustable-lengths, two body abutment structure between upper and lower pulley-type hook 3,4.Top sheave formula hook 3 has 10, one sections of terraced bar 10 lower ends one section of solid square bar 7(of connection of one section of terraced bar of downward connection to see Fig. 1,3,4), solid square bar 7 is along upper and lower spaced multiple horizontal perforations 5; Corresponding wheeled hook 4 upper ends that glide are fixedly connected with and lean out the solid square beam 8(of a section and see Fig. 5,6), in solid square beam 8 sections of leaning out 9, there are upper and lower two horizontal perforations 5 of arranging, by bolt 6, solid square bar 7 is connected and fixed with solid square beam 8, move bolt and insert different horizontal perforation 5, realize between upper and lower pulley- type hook 3,4 distance adjustable.
By to selecting different bolt horizontal perforation 5(adjustment holes) be connected with the bolt of bottom connector, realize the spacing of adjusting upper and lower hanging point pulley, thereby realize the needs that hang on different spacing double bundle conductor.
When use, two top sheave formula hooks 3 hang on the wire of top, and two wheeled hooks 4 that glide hang on the wire of below.According to the distance between two wires, can suitably adjust the distance between upper and lower pulley- type hook 3,4, to meet the on-the-spot needs that use.The a set of rope ladder head of the design can replace the rope ladder head of plurality of specifications, has highly versatile, easy to use, and minimizing instrument is equipped with, cost-saving feature.
The design also can adopt between upper and lower pulley- type hook 3,4 places ladder bars and peg graft, and forms Telescopic rod structure, fixes (figure slightly) in the middle of then by horizontal slotting Bolt to position.
