Utility model content
For making up the deficiencies in the prior art, the utility model provides a kind of simple to operate, easy to use, and safe and reliable mountain area arch bridge cable hoisting stayed-buckle cable parts instrument a little.
The utility model is achieved by the following technical solution:
A kind of mountain area arch bridge cable hoisting stayed-buckle cable parts instrument a little, its special character is: comprise oblique pull snap close, expansion bend and contracting cylinder, described expansion bend comprises four pieces of semi-cylindrical recesses, every two pieces of semi-cylindrical recesses fasten formation two cylindrical tubes respectively, and described oblique pull snap close is successively through two cylindrical tubes; Described expansion bend inner surface is provided with some circles for compressing the rubber press strip of the rib-like of oblique pull snap close; Two cylindrical tubes of described expansion bend are respectively equipped with external screw thread near position, and described contracting tube inner surface is provided with internal thread, and two cylindrical tubes of expansion bend are flexibly connected by screw thread with contracting cylinder; Described contracting cylinder comprises two panels semi-cylindrical cylinder, and this two panels semi-cylindrical cylinder is connected and fixed by closing arm, and contracting drum outer wall is provided with pivoted arm.
Mountain area of the present utility model arch bridge cable hoisting stayed-buckle cable parts instrument a little, and described semi-cylindrical recesses edge is provided with several bolt holes, and two pieces of semi-cylindrical recesses are fixedly connected with on bolt hole by bolt anchoring, is conveniently passed wherein by oblique pull padlock.
Mountain area of the present utility model arch bridge cable hoisting stayed-buckle cable parts instrument a little, a circle projection is respectively equipped with on two cylindrical tube outer walls of described expansion bend, be connected with steel rib between two projections, steel rib adopts two half steel ribs mutually to insert and is slidably connected, the convenient collapsing length changing expansion bend.
Further, mountain area of the present utility model arch bridge cable hoisting stayed-buckle cable parts instrument a little, and the external thread rotary on two cylindrical tubes of described expansion bend is to contrary and match with the internal thread stating contracting tube inner surface.
Mountain area of the present utility model arch bridge cable hoisting stayed-buckle cable parts instrument a little, and described oblique pull snap close adopts high strength steel strand to make, durable.
The beneficial effects of the utility model are: the utility model changes the collapsing length of expansion bend by rotating contracting cylinder, expansion bend inside is tightened up mutually, reach stayed-buckle cable fine setting, thus the lifting elevation of adjustment arch box tap points, convenient and practical, safe and reliable, with low cost.
