It is structure that intermediate nodal axisn 41 of the invention, which is seperated with the left flange 42a of the middle node at its both ends and right flange 42b of middle node,
Knot, the left flange 42a of middle node and the right flange 42b of middle node pass through retaining mechanism 5 respectively and intermediate nodal axisn 41 realizes the company of fastening
It connects.As the left flange 42a of middle node and the right flange 42b wear damage of middle node, disassembly and driving end half hub section 1a and driven end
The resilient sleeve 2 and pin 3 of half hub section 1b connection dismantle middle node component 4, unclamp and clamp the solution latching flange locking machine of extrusion screw 53
Middle node component 4 is radially moved into the edge of driving end half hub section 1 and 2 ring flange of driven end half hub section by structure 5, appropriate to tilt
Intermediate nodal axisn 41 exposes the left flange 42a or right flange 42b of middle node of the middle node to be replaced and carries out replacement handling, then will in
Segmentum intercalaris component 4 resets, and installs resilient sleeve 2 and pin 3 and docks with driving end half hub section 1 and 2 ring flange of driven end half hub section, then will
The left flange 42a of the middle node being replaced or the right flange 42b of middle node are fastenedly connected with flange retaining mechanism 5.
The present invention is especially suitable for the pin couplers of long distance between axles, such as pin coupler used for cooling tower, and not needing will be whole
The middle node of a pin coupler unloads taking-up completely and replaces entire middle node, can be in cooling tower only to the middle node of damage
Left flange or the left flange of middle node are replaced.
