Clamping apparatus for joining two flanges

摘要

A clamping apparatus for joining two flanges by means of clamping members circumferentially spaced around the flanges and radially forced inwardly to engage and compress the two flanges in a clamping space of the clamping members includes a clamping roller chain extending around the clamping members with the clamping rollers engaging the outer surfaces of the clamping members which are supported independently of the clamping chain by a support ring in such a manner as to be freely movable in radial direction but under the control of an operating rim which engages all the clamping members for simultaneous radial movement and a tensioning structure for the clamping roller chain which is associated with said guide rim for forcing said clamping members inwardly into firm engagement with said flanges or releasing the clamping members and moving them outwardly out of engagement with the flanges.
