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.
Claims14
A clamping device for temporarily connecting two ends of a large-pipe element, comprising at least two connection devices and a rigid connection rod, with the connection devices being arranged at the ends of the connection rod, characterized in that the connection device is a gripping device which comprises
- a base frame,
- a joint that connects the base frame and connection rod,
- at least two gripping jaws opposite one another that are arranged below the joint, wherein each gripping jaw comprises at least one gripping surface that bears against the pipe element in the closed state of the clamping device, wherein
- at least one gripping jaw comprises at least one gripping element that has a mechanism for altering the position,
- the gripping element comprises a gripping surface, and
- at both ends of the connection rod at least one gripping device each is mounted in an articulated manner, and the gripping device is respectively oriented such that the openings of two different gripping devices, which openings are located between the gripping jaws, point in the same direction and the openings of two different gripping devices are positioned on the same side of the connection rod.
