Technical field
The utility model relates to extra high voltage direct current transmission line maintenance, live line working Work tool field, particularly relates to a kind of extra high voltage direct current transmission line triple strain jig.
Background technology
At present, along with the develop rapidly of power industry, long distance, Large Capacity HVDC Techniques become the cutting edge technology of big electrical network, and first extra high voltage direct current transmission line of China builds up, and will formally run.Extra high voltage direct current transmission line and existing 500kV extra high voltage network and the 1000kV AC extra high voltage transmission line that puts into operation in recent years relatively have substantial leaping.But because transmission line equipment is more on the circuit, so the suffered load of connection gold utensil on the transmission line is bigger, and in Maintenance and Repair equipment and live line working process, must lay down this load earlier, during again owing to Maintenance and Repair equipment and live line working is the high-altitude manpower operation, and transmission line band extra-high voltage direct-current, therefore existing transmission facility and maintenance utensil all can not satisfy extra-high voltage direct-current transmission hotline maintenance needs, thereby develop corresponding Maintenance and Repair equipment and live line working special tool utensil becomes the importance that guarantees the extra high voltage direct current transmission line safe and stable operation.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, a kind of extra high voltage direct current transmission line triple strain jig simple, safe, laborsaving and easy to use to be provided.
In order to realize above purpose, a kind of extra high voltage direct current transmission line triple strain jig that the utility model provides, comprise: stringing hydraulic pressure screw mandrel, card and back card before it also comprises, preceding being installed on the connection lead side cross link plate continuous with being connected gold utensil one end, the back be installed on be connected the towing plate that the gold utensil other end links to each other on, preceding card with afterwards block between connect by stringing hydraulic pressure screw mandrel.
Card center, described back is provided with first groove that is complementary with towing plate, and its two ends are respectively equipped with first through hole that connects stringing hydraulic pressure screw mandrel, has on the described first groove two side and the second fixing through hole of towing plate.
Before described card comprise the turnover panel card, renovate, rotating shaft, first connecting plate and second connecting plate, renovating an end connects by rotating shaft and turnover panel card, renovating the other end connects with turnover panel card one end and first connecting plate, one end by first bolt simultaneously, the turnover panel card other end connects by second bolt and second connecting plate, one end, and the other end of first connecting plate and second connecting plate connects with a stringing hydraulic pressure screw mandrel respectively.
The center of described turnover panel card with renovate corresponding seat and be respectively equipped with the circular hole and second groove that is connected lead side cross link plate.
The utility model is compared with the prior art, and shows that fully its superiority is: simple, safe, laborsaving and easy to use etc.
