Definitions

• the invention relates to a device for vertical mounting of tubes, which has a cylinder-segment-like base member and a pivotable at least one pivot joint connected to the base element door element and a pivot joint opposite arranged closure.
• Such devices are used, for example, to assist the handling of drill pipes in the area of offshore drilling platforms.
• the drill pipes surround the drill and are lowered from the drilling platform.
• the drill pipes are typically made of a plurality of successively arranged and interconnected pipe segments. The individual pipe segments are connected in series with the drill pipe already supported by the drilling platform and lowered after the joining process has been carried out.
• special devices are required to prevent slippage of the pipe and a resulting sinking of the drill pipe in the sea.
• the device is typically white after opening the door element pushed laterally over the pipe to be held. Subsequently, a closing of the door element and a closing of the closure, to ensure a secure mounting of the tube.
• the object of the present invention is to construct a device of the initially mentioned type such that a reliable signaling of a proper closing of the device is provided.
• the closure has a pivotable locking, which engages behind a locking bolt in a locked state with a locking profile, that in the region of the pivotable locking a safety pin and a locking plate are arranged and that the locking plate position dependent at least one recess for the Locking pin releases or closes.
• the securing bolt protrudes out of the device and can easily be visually recognized or manually probed.
• the positioning of the securing bolt can be recognized by an operator and the assumption of a proper closure condition can be checked.

• the base member and the door member is formed with the closure for holding drill pipes.
• a high mechanical stability is achieved in that the locking pin is supported by the base member.
• both the latch profile and the backup plate are arranged pivotable relative to a secondary axis.
• a first guide for the safety bolt is provided by the fact that one of the recesses for the safety pin is arranged in a rigidly connected to the door member support plate for supporting the closure.
• a second variable position guide for the safety pin is formed by a coupled to the bolt profile and a handle-holding support plate provided with a recess for the safety pin and is mounted rotatably relative to a central axis.
