Description

A kind of large span cross-arm jig assembly
Technical field
The utility model relates to electric power tool technical field, especially a kind of large span cross-arm jig assembly.
Background technology
At present, due to modern Economy Development needs and to leap thing safe distance requirement, the design of electric power line pole tower is more and more higher, diameter of wire is increasing, the stress of conductor also increases thereupon, all need to use cross-arm jig when carrying out wire operation and carry out lifting lead wire, but utilize traditional cross-arm jig to carry out there is following defect when promoting operation: one, due to stress when common cross-arm angle section can not bear lifting lead wire, easily occur angle section bending, fracture thus cause the generation of line accident with common cross-arm card; Two, existing filament bar mode of carrying can not meet the requirement of large span pole tower operation, easily to cause in operation process because screw mandrel discontinuity or strength are inadequate, causes Work tool damage and electric shock accidents occurs.
Summary of the invention
The purpose of this utility model is exactly the problems referred to above existed for the cross-arm jig in existing construction operation, and provide a kind of flexible to operation, coefficient of safety is high, can be applicable to the cross-arm jig assembly of large span operation.
Concrete scheme of the present utility model is: a kind of large span cross-arm jig assembly, there is cross-arm accessory, the two ends of cross-arm accessory are respectively provided with a deck, tapped through hole is provided with in the middle of described deck, the top of each deck is provided with sleeve pipe, described internal surface of sleeve pipe is provided with screw thread, the outside of each sleeve pipe is provided with an operating grip, successively pass through each deck, with corresponding sleeve pipe, a thread-tightening lead screw is all housed, the lower end of described thread-tightening lead screw is hinged with insulation pulling plate, and the lower end of insulation pulling plate is hinged with thread hook by connector; The outside being positioned at thread-tightening lead screw at the two ends of cross-arm accessory is respectively provided with a safety bolt.
Be provided with two cover cross-arm fixtures at the medium position of described cross-arm accessory in the utility model, described cross-arm fixture includes stay bolt and hook, and described hook has bar hole, and stay bolt is threaded with cross-arm accessory through bar hole.
Operating grip described in the utility model is the ratchet spanner arranged that matches with sleeve outer wall.
Deck described in the utility model is also provided with pad with between corresponding sleeve pipe.
Cross-arm fixture operationally can be fixed on shaft tower by the utility model, then the deck on both sides is moved left and right and adjust to correct position, again by rotating the operating grip on cross-arm accessory both sides, regulate two thread-tightening lead screw liftings, hook wire to facilitate the thread hook of insulation pulling plate front end and carry out corresponding operation; The utility model structure is simple, and easy to operate, job safety coefficient is higher, can adapt to the operating environment of large span simultaneously, have good actual application value.
Accompanying drawing explanation
Fig. 1 is the utility model general structure schematic diagram;
Fig. 2 is K place structure enlarged diagram in Fig. 1.
In figure: 1-thread-tightening lead screw, 2-insulation pulling plate, 3-operating grip, 4-stay bolt, 5-bar hole, 6-hook, 7-cross-arm accessory, 8-safety bolt, 9-connector, 10-thread hook, 11-sleeve pipe, 12-pad, 13-deck.
