Abstract
A device for vertically holding pipes for elevator systems on oil drilling platforms has a basic element with a pivotable door element. A closing movement for forming a cylinder liner is carried out by a lockable adjusting cylinder. The cylinder liner is formed by interchangeable cylinder segments to form a cylinder liner of different size diameters in the basic element and door element. The cylinder segments are arranged interchangeably via rear guide profiles and associated profile rails in the basic element and door element. Upper sides of the cylinder segments are connected to corresponding receptacles via retaining rings which are able to be pushed on horizontally. By receiving pipes in the cylinder liner and an occurring load, a spring-loaded actuating arm is adjustable in height via a cylinder segment. Locking of the hydraulic adjusting cylinder for the closing movement is controllable via an associated load sensor.
