Description
Technical field
The present invention relates to hoisting and hanging field, specifically a kind of shear-clamp type electric pole dedicated lifting hook.
Background technology
During line construction unit on-site hoisting electric pole, generally use steel wire rope as mainly lifting aid, utilize steel wire rope by fixing for electric pole colligation lifting.Because electric pole volume is little, weight big, need more manpower less important work, there is potential safety hazard and be unfavorable for the raising of work efficiency.
Because electric pole contacts with ground, supporter is placed after needing manually to be lifted electric pole one end, or select to excavate the ground of electric pole center, electric pole and ground is made to have the road clearance, so that using steel wire rope to be bundled in cement electric pole central spot, then hoisting electric pole, manually unties wire line hitch after having lifted.
Use steel wire rope to be bundled in the Hoisting Program of cement electric pole central spot, because electric pole contacts with ground, need manually to be lifted electric pole one end.Because the little weight of electric pole volume is big, need more manpower repetitive operation, too much use manpower operation there is more construction safety hidden danger and be unfavorable for the raising of work efficiency.
Summary of the invention
The efficiency occurred in handling process for electric pole is low, the problem that there is potential safety hazard, and the present invention provides a kind of shear-clamp type electric pole dedicated lifting hook, can avoid the generation of the problems referred to above.
The present invention solves its technical problem and is adopted the technical scheme that:
A kind of shear-clamp type electric pole dedicated lifting hook, including two around the hinged hinge bar of rotary shaft, an arc fixing chuck plate it is provided with in hinge bar bottom, it is each provided with half circular mounting circle in arc fixing chuck plate both sides, it is provided with friction plate inside described semicircle installing ring, between semicircle installing ring and friction plate, is provided with leaf spring.
Further, described installing ring side is provided with hole, some location, is respectively provided with a bolt, is connected by chain between two bolts in the hole, location on two arc fixing chuck plates, and described chain annular is centered around the downside of electric pole.
Further, being provided with an annular mounting groove, be provided with arc-shaped rack in described annular mounting groove, be provided with knob, be provided with gear below described knob on the arcwall face of semicircle installing ring in described semicircle installing ring, described gear is meshed with arc-shaped rack.
Further, the arcwall face of described semicircle installing ring being provided with hole, location, is provided with alignment pin, is provided with corresponding screens hole simultaneously on arc-shaped rack in hole, described location, alignment pin is fixed in screens hole through hole, location.
Further, being provided with female thread in described screens hole, described alignment pin end is provided with external screw thread, and alignment pin is threaded connection and is arranged in screens hole.
The invention has the beneficial effects as follows:
Inventive article cost is low, can large-scale use, lifting carrying electric pole that can be simple and efficient, reduce manual steps, when reducing because manually bundling electric pole, the unsafe factor produced because of the rolling of electric pole, and the raising of beneficially work efficiency.
