Description
Technical field
The present invention relates to the bolt clipper of a kind of big line footpath wire, belong to line construction technical field.
Background technology
Increase along with society's power consumption demand, line voltage distribution grade is more and more higher, line channel is increasingly sophisticated, and transmission line of electricity (particularly 220kV, 500 kV circuits) the most more and more have employed the mode that tension stringing sets up, and causes wire, ground wire needs to cut-off in high-altitude.In the maintenance of daily circuit with when safeguarding, it is desirable to the situation cut-offfing, crimping lead wire and earth wire in high-altitude is of common occurrence, and bolt clipper becomes indispensable instrument in line construction and maintenance.Complicated for line channel, to hand over across high ferro, canal or other electric pressure circuits, shortening has a power failure, the Construction and Maintenance time is greatly improved line powering reliability, and economic results in society.In addition, the shear surface of bolt clipper is the most smooth, whether meet the requirement of construction technology, whether there will be pine stock, broken lot, grand stock phenomenon near fracture, shearing quality whether process requirements meeting crimping etc. series of problems also directly influence circuit can for a long time, high load capacity safe and reliable operation.
At present, bolt clipper both domestic and external is of a great variety, divides by handle arrangement, has single link arm formula and doubly-linked arm-type；Dividing by section cutting edge, have one side sword and double-sided blade etc., generally speaking bolt clipper includes mechanical linkage structure and hydraulic structure two kinds.The feature of mechanical linkage structure bolt clipper is simple in construction, easy to operate, but the shortcoming of this bolt clipper is the most prominent, it is simply that the requirement of the operating personnel in work high above the ground is higher, and the adaptation ability to the most collinear footpath is poor in addition, otch is the most carefully and neatly done；The feature of the bolt clipper of hydraulic structure is the muscle power utilizing hydraulic principle to save operating personnel, but the heaviest underaction in the front portion of bolt clipper, and angle is single simultaneously, and limits it and use.
Wire for big line footpath, also there is no special bolt clipper both at home and abroad, domestic bolt clipper maximum can be suitable for LGJ630, the most maximum allowable in LGJ800, in transformer station, during bus construction, occur in that many new problems along with constantly promoting of electric pressure, the maximum bus line footpath used in such as 500kV transformer station has reached LGJ1440, and existing bolt clipper obviously can not meet demand.
Present stage cuts off the general method using steel core and aluminium stock separately to process for the wire in big line footpath, the most first with saw bow sawed-off for aluminium stock, steel core is cut off again with bolt clipper, this kind of method engineering time is longer, higher to the requirement of workmen's technology, add construction cost, and it being difficult to ensure that the requirement of construction technology, its use of job site for circumstance complication has some limitations.
Summary of the invention
Solved by the invention technical problem is that uses steel core and aluminium stock to separate the method processed for big line footpath Bus cutting, and the engineering time is longer, technology requirement is higher, adds construction cost, and the problem being difficult to ensure that the requirement of construction technology.The bolt clipper of the big line footpath wire of the present invention, it is adaptable to big line footpath wire, under ensureing line construction and repair quality premise, promote operating efficiency, alleviate the burden of work high above the ground personnel, also meet the needs of China's electric power industry development simultaneously, have and have broad application prospects.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
nullA kind of bolt clipper of big line footpath wire，It is characterized in that: include oil storage bar、Action bars、Oil return push rod and broken string binding clip，Described action bars is arranged on the side of oil storage bar by being positioned at the annular sling of front end，Described action bars turns clockwise with annular sling for axle and oil storage bar closes up，The front end of described oil storage bar is provided with oil cylinder，The front end of the oil cylinder that described oil return push rod is arranged on，It is positioned at place below action bars on described oil return push rod and is provided with control valve，Described control valve is connected with action bars by spring，The front end of described oil return push rod connects broken string binding clip，Described broken string binding clip includes revolving body、Cutting blade and fixing blade，Described revolving body is U-shape，Described cutting blade is embedded in the opening portion of revolving body，Described fixing blade is fixed on the opening portion of revolving body，Described fixing blade forms the pincers line circular hole for broken string with cutting blade，Described cutting blade is connected with oil return push rod，When pressing under described action bars，Control valve and start the reach of oil cylinder pushing oil return push rod，Drive cutting blade moves forward，Coordinate fixing blade to carry out big line footpath conductor cord disconnection pincers to cut.
The bolt clipper of aforesaid a kind of big line footpath wire, it is characterised in that: described fixing blade is fixed on the opening portion of revolving body by steady pin.
The bolt clipper of aforesaid a kind of big line footpath wire, it is characterised in that: described action bars and the oil storage bar face of fitting are provided with postive stop baffle.
