Abstract:
1. A device for vertically holding pipes of differing diameter for elevator systems for picking up, lifting and depositing a line of pipes or individual pipe segments onto oil platforms, the device comprising: a basic element for forming a cylinder liner having a swivel joint for an associated door element to complete the cylinder liner, wherein the swivel joint has a closure on the basic element and has a locking pin on the door element; a hydraulic closing cylinder connected to the closure for controlling closing movement of the closure, wherein cylinder segments for forming the cylinder liner in different size diameters are arranged interchangeably in the basic element and the door element by rear guide profiles and associated profile rails in the basic element and the door element; wherein upper sides of the individual cylinder segments are connected to corresponding receptacles by retaining ring segments that are arranged so as to be able to be pushed on horizontally; a spring-loaded actuating arm that is height adjustable, wherein, during reception of pipes in the cylinder liner and an occurring load, the spring-loaded actuating arm is adjustable in the height thereof via one of the cylinder segments; and a load sensor for controlling locking of a hydraulic adjusting cylinder arranged for closing movement of the door element.
