Two panels semi-cylindrical cylinder, the two panels semi-cylindrical cylinder are connected by closing arm, and contracting drum outer wall is provided with pivoted arm.
The mountain area arch bridge cable hoisting stayed-buckle cable of the present invention parts instrument a little, if the semi-cylindrical recesses edge is provided with
Dry bolt hole, two pieces of semi-cylindrical recesses are fixedly connected on bolt hole by bolt anchoring, convenient by stayed-buckle cable
Pass through.
The mountain area arch bridge cable hoisting stayed-buckle cable of the present invention parts instrument, two cylindrical tube outer walls of the compensator a little
It is upper to be respectively equipped with a circle projection, steel rib is connected between two projections, steel rib is mutually inserted using two half steel ribs and is slidably connected,
The convenient collapsing length for changing compensator.
Further, mountain area arch bridge cable hoisting stayed-buckle cable of the invention parts instrument, two cylinders of the compensator a little
External screw thread on shape cylinder is oppositely oriented and matches with the female thread for stating contracting tube inner surface.
The mountain area arch bridge cable hoisting stayed-buckle cable of the present invention parts instrument a little, and the stayed-buckle cable adopts high strength steel strand
Make, it is durable.
The invention has the beneficial effects as follows：The present invention changes the collapsing length of compensator by rotating contracting cylinder, makes in compensator
Portion mutually tightens up, and reaches stayed-buckle cable fine setting, so as to adjust the lifting elevation of arch box tap points, convenient and practical, safe and reliable, into
This is cheap.
