Abstract
The invention discloses a pipeline ballast mechanism of a pipe laying tensioner, comprising a ballast mechanism erected on a ballast beam and a crawler-type clamping plate connected to the ballast mechanism, wherein the ballast mechanism applies pressure to the crawler-type clamping plate and presses a pipeline in contact with the crawler-type clamping plate; the ballast mechanism comprises a ballast oil cylinder fixed on the ballast beam; the ballast oil cylinder produces pipeline ballast force which acts on the crawler-type clamping plate to press the pipeline; and the ballast beam bears reacting force transmitted by the ballast oil cylinder. The invention adopts the ballast oil cylinder to replace an air spring to serve as a mechanism for applying pressure and bearing; because the bearing capacity of an oil cylinder is far stronger than that of an air spring, the ballast mechanism still can provide large positive pressure to apply on the clamping plate under the condition of limited boundary dimension of the tensioner.
