Abstract
Provided is a clamping device for temporarily connecting two ends of a large-pipe element with at least two connection devices and a rigid connection rod, with the connection devices being arranged at the ends of the connection rod. The clamping device is used to connect and secure the plate ends of large pipes and large-pipe elements. The clamping device is, unlike the known tack welds or auxiliary connectors (cleats), mobile, reusable, and versatile. It can be mounted quickly and securely on pipe elements of different diameters in order to reduce the load on the tack weld and, in the event of tack weld failure, take the place of it.
Claims15
A clamping device for temporarily connecting two ends of a large-pipe element, comprising:
- at least two connection devices;
- and
- a connection rod, wherein
- the connection devices are arranged at ends of the connection rod,
- each connection device is a gripping device that is mounted to one of the ends of the connection rod in an articulated manner, each gripping device comprises:
- a base frame;
- a joint that connects the base frame and connection rod;
- and
- at least two gripping jaws that are arranged below the joint and oppose one another such that an opening is provided between the at least two gripping jaws in an open state of the clamping device, wherein
- each gripping jaw includes at least one gripping surface that bears against the large-pipe element in a closed state of the clamping device,
- at least one gripping jaw includes at least one gripping element that has a mechanism for adjusting a position of the gripping element,
- the gripping element includes the gripping surface, and
- each gripping device is respectively oriented such that the openings of the at least two gripping jaws point in a same direction and are positioned on a same side of the connection rod to receive the large-pipe element.
