Title:
RUBBER ROD DRAWING DEVICE FOR BOX GIRDER PRESTRESSED PIPELINES
Document Type and Number:
WIPO Patent Application WO/2024/016707
Kind Code:
A1
Abstract:
A rubber rod drawing device for box girder prestressed pipelines. Rod drawing wheel groups are all arranged on a movable working platform and are distributed at intervals in a direction perpendicular to the drawing direction of rubber rods, and the rod drawing wheel groups respectively correspond to the rubber rods to be drawn. A jack for balancing the frictional resistance experienced by the rubber rod is provided between two adjacent rod drawing wheel groups, and a telescopic rod of the jack extends out of the movable working platform and abuts against an outer part of a prestressed pipeline. Each rod drawing wheel group is provided with two rows of rod drawing wheels, which are arranged in parallel and are distributed in the drawing direction of the rubber rod, wherein the rod drawing wheels are equipped with rod drawing wheel electric motors for driving same to rotate, the rotation axis of the rod drawing wheels is perpendicular to the extension axis of the rubber rod, and the peripheral edges of the two rows of rod drawing wheels in the same rod drawing wheel group respectively abut against two sides of the rubber rod. The jack is configured to abut against the outer part of the prestressed pipeline so as to balance the frictional resistance experienced by the rubber rod, thereby ensuring the stability and safety of the whole movable platform during usage.
