Description
Technical field
The utility model relates to transmission line and sets up with the construction apparatus, particularly relates to saddle line lifter and construction method thereof that transmission line OPGW tangent tower annex is installed.
Background technology
It generally is that one group of stringing preformed armor rods is installed respectively on the OPGW of tangent tower both sides that OPGW tangent tower annex is installed, then by two chain block or other wire grips traction stringing preformed armor rodses that are hung on the iron tower, after making OPGW between two groups of stringing preformed armor rodses lax preformed armor rods and wire clamp are installed thereon, and wire clamp is connected on the gold utensil string, ease out chain block or other wire grips subsequently again and finish annex and install.Shortcomings such as there is the operation complexity in this method, efficient is low, labour intensity is big, construction cost height.
The utility model content
The purpose of this utility model provides a kind of saddle line lifter simple in structure, convenient and practical, that install as OPGW tangent tower annex.
This novel purpose is achieved in that a kind of saddle line lifter, comprises the ratchet wire grip, and four pulleys are installed on the crossbeam that two be arranged in parallel, and wherein, two head sheaves are installed in rotation between two crossbeams, and lay respectively at the left and right two ends of crossbeam; Two other middle pulley structure is installed on the sustained height position of two crossbeams top in the same manner: two are supported angle steel and are welded on one to one respectively on the crossbeam in two crossbeams, middle pulley is installed in rotation on two and supports between the angle steel, and the left and right crossbeam top that is symmetrically located at of above-mentioned two middle pulleys; Described ratchet wire grip is arranged between two middle pulleys, and two steel wire ropes are articulated on the left and right hook of ratchet wire grip through fag end respectively, and the outer end of two steel wire ropes connects firmly with a kiss-coating thread-lifting hook after walking around a middle pulley and a head sheave separately; Between two middle pulleys, be provided with two stay hooks on two crossbeams.
Above-mentioned two crossbeams are angle steel; All be welded with the reinforcement angle steel on described two support angle steel.
Above-mentioned two crossbeam bottoms are welded with cushion block, stay hook pass from bottom to top on the cushion block the hole after fixed by nut on two crossbeams.
Above-mentioned pulley structure is: wheel body is fixed on the axle, and axle is provided with copper sheathing.
This novel beneficial effect is: simple in structure, convenient and practical, simple to operate, operating efficiency is high, labour intensity is low, the easier assurance of OPGW tangent tower annex installation quality, reduced construction cost, has good application prospects.
