Embodiment Construction

[0022] The device essentially consists of a base element 1 with a door element 3 pivotable by means of a hinge pin 2 , locked in the closed state by means of a locking element 4 on the base element 1 and controllable by means of an adjustment cylinder 6 (adjustable) to form the cylinder liner 5.

[0023] The cylinder liner 5 is formed by cylinder segments 7 which are fastened interchangeably to the base element 1 and the door element 3 . To this end, the cylinder section 7 is connected to a rear guide profile 8 which can be pushed into an associated (correspondingly assigned) profile rail 9 and secured.

[0024] In the upper region, the cylinder section 7 is connected via a horizontally displaceable retaining ring 10 to a corresponding receptacle 21 for the cylinder section 9 .

[0025] In this embodiment, the cylinder section 7 is connected to a spring-loaded actuating arm 11 and, in the event of an inserted tube and thus a load, acts on a load cell 12, which blocks the adju...

Abstract

The invention relates to a device for vertically securing pipes having various diameters for elevator systems on oil drilling platforms, where a base element is arranged with a pivotable door element, wherein the closing movement for forming a cylinder liner can be carried out by a lockable actuating cylinder. The cylinder liner is formed by replaceable cylinder segments in order to form a cylinder liner having diameters of different sizes in the base element and door element. To this end, the cylinder segments are replaceably arranged by means of rear-sided guide profiles and associated profiled rails in the base element and door element. The upper sides of the individual cylinder segments are connected to corresponding receiving elements via horizontally slidable holding rings. By accommodating pipes in the cylinder liner and the occurrence of load, a spring-loaded actuating arm can be height-adjusted via a cylinder segment and a locking of the hydraulic actuating cylinder can be adjusted for the closing movement via an associated load sensor.

Description

technical field [0001] The invention relates to a device for vertically holding pipes of different diameters for use in elevator systems for picking up, lifting and placing pipelines or sections of pipes on oil platforms, comprising basic elements for forming cylinder liners, which Complete the bushing with a swivel joint for the associated door element, which has a latch spaced apart and has a pivotable latch (catch) with a latch pin and closes The movement is controllable (adjustable) by associated (or correspondingly configured) hydraulic adjustment cylinders. Background technique [0002] Such a technical solution is known in various embodiments in which opening and closing is achieved by adjusting cylinders via hydraulic control mechanisms. The disadvantage here is that this configuration is only designed for a single pipe size and that the cylinder liner can only be retrofitted on site at great expense. The fact that the opening movement of the door element under loa...
