Abstract
A leap-type aluminium-alloy flexible ladder head for overhead power transmission lines comprises an insulation flexible ladder, and a flexible ladder head is arranged at a terminal of the insulation flexible ladder. A U-shaped tool ring is arranged between tow ladder rods of the insulation flexible ladder, and a flexible-ladder-head hanging ring is arranged at a central portion of the U-shaped tool ring. A two-head lead screw passes through the flexible-ladder-head hanging ring with one end fixed on the flexible-ladder-head hanging ring and the other end connected with a bearing hook. The successful development of the leap-type aluminium-alloy flexible ladder head for overhead power transmission lines solves the problems existing in the practical works and reduces the labor intensity of work personnel. The flexible ladder head has the advantages of simple process, portability, flexibility, easy operation, high safety and high generality, and allows the original flexible ladder head to be reinforced without influence on the normal use of the flexible ladder head, so that the stability and the safety are increased, and the conventional tools are processed and modified, thereby greatly saving costs. The flexible ladder head has a leading position in the industry, and is highly valued in popularization.
Description
Technical field
The utility model relates to that transmission line is charged, during interruption maintenance, on the lead long apart from the mobile operating position, cross over the instrument of barrier on the lead.
Background technology
Overhead transmission line running environment more complicated, various buildings are crossed in the residential area that is positioned at that has, and what have is positioned at remote mountain area, is that ravines and guillies criss-cross is made troubles to power transmission lines overhauling everywhere, and particularly charged repairing double bundle conductor is changed conductor spacer.As run into following two kinds of situation: a kind of is that ground has and do not have suitable position to hang software, and another kind is that higher shaft tower operating personnel can't hang software at defective locations, and can only take near shaft tower, to hang software.At this moment far away like defective locations, need the equal potential working personnel to slide, when arriving defective locations,, very difficult when crossing conductor spacer because fruit is adopted traditional rope ladder head.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned deficiency a kind of overhead transmission line great-leap-forward aluminium alloy rope ladder head is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of overhead transmission line great-leap-forward aluminium alloy rope ladder head; Comprise insulated flexible ladder, be provided with rope ladder head, between insulated flexible ladder two terraced bars, be provided with U type tool links in the end of insulated flexible ladder; The middle part of U type tool links is provided with the rope ladder head link; Through the double end leading screw, an end of double end leading screw is fixed on the rope ladder head link on the rope ladder head link, and the other end is connected with the load hook.
Above-mentioned overhead transmission line great-leap-forward aluminium alloy rope ladder head; Said double end leading screw comprises leading screw, leading screw sleeve and last leading screw down; The bottom of following leading screw and rope ladder head link connect firmly; The lower end of leading screw sleeve and upper end are threaded with the upper end of following leading screw and the lower end of last leading screw respectively, and the upper end of last leading screw and load hook flexibly connect, the load hook rotation relatively of last leading screw.
Adopt technique scheme; The utility model has following advantage: overhead transmission line great-leap-forward aluminium alloy rope ladder head is in the middle of original rope ladder head, to install one additional can dismantle; And can promote the special-purpose hook of operation with rope ladder and operating personnel; The time run into barrier on the lead in work, can utilize leading screw to tighten up, loosen and reach the purpose that makes the rope ladder head across obstacle.Succeeding in developing of overhead transmission line great-leap-forward aluminium alloy rope ladder head solved the difficult problem in the real work, reduced operating personnel's labour intensity; It is simple to have the processing of making, light and flexible, the characteristics of simple to operate, high safety, highly versatile; In addition, overhead transmission line great-leap-forward aluminium alloy rope ladder head normally uses, also original rope ladder head is reinforced not damaging rope ladder head, and stability, fail safe are better, and existing Work tool carries out process and remould, practices thrift substantial contribution.Itself not only has the leading position in the same industry, also has excellent generalization values.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the utility model removes the structural representation that holds hook and double end leading screw.
Fig. 3 is an A position right view among Fig. 1.
Embodiment:
Like Fig. 1, Fig. 2 and a kind of overhead transmission line great-leap-forward aluminium alloy rope ladder head shown in Figure 3, comprise insulated flexible ladder 2, be provided with rope ladder head 1 in the end of insulated flexible ladder 2; Between insulated flexible ladder two terraced bars, be provided with U type tool links 3, the middle part of U type tool links 3 is provided with rope ladder head link 4, passes through the double end leading screw on the rope ladder head link 4; One end of double end leading screw is fixed on the rope ladder head link 4; The other end is connected with load hook 7, and said double end leading screw 3 comprises leading screw 5, leading screw sleeve 8 and last leading screw 6 down, and the bottom of following leading screw and rope ladder head link connect firmly; The lower end of leading screw sleeve 8 and upper end are threaded with the upper end of following leading screw and the lower end of last leading screw respectively; The upper end of last leading screw 6 and load hook 7 flexibly connect, the load hook rotation relatively of last leading screw, and the load hook adopts material identical with former rope ladder head.
The utility model improves on original rope ladder head basis:
1, ties up pricking place in the suspension of aluminium alloy rope ladder head and increase fixedly link.
2, utilize the suitable double end leading screw of length to transform, one is fixed on the rope ladder head link, and one is transformed into connecting band tamper seal mouthpiece power hook; The double end leading screw adopts elevating capacity greater than 10KN, can calculate by 1kn according to rules regulation people carrier.
3, in order to make the double end leading screw not influence the suspension of aluminium alloy rope ladder head, leading screw adopts to live with rope ladder head and is connected, and can dismantle as required.
4, the load hook utilizes the cabling hook on original aluminium alloy rope ladder head to transform, and guarantees when load moves, can not injure lead, can well on lead, slide again.
