Abstract: An apparatus to support a tubular member such as pipes, in particular in deep drilling, in particular in the field of oil and gas production, for instance in deep drilling A plurality of linear actuators for moving clamp elements are orientated with their actuator axis in a cone angle of a sliding surface for the clamp elements. The linear actuators are positioned in the clamp elements.

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.

Abstract: For holding a pipe, rod or the like, such as a section of a pipe string of an offshore oil drilling rig, an apparatus includes a clamping device insertable into a support body. The clamping device includes a device body with a central opening bounded by an inner circumferential surface that conically tapers at a cone angle. The device further includes clamp elements that are received in the central opening of the device body and that each have a radially outer surface sloping along the cone angle to slide along the inner circumferential surface of the device body, and a radially inner clamping surface to clamp against the coaxially arranged pipe. A holding element respectively connects each clamp element to a linear actuator stroke element that is similarly tilted at the cone angle. The linear actuator may be received in a receiver shaft of the device body.

Abstract: An apparatus for manipulating pipes has a base component and a counter element pivotally mounted relative to the base component. The base component and the counter element together define in a closed state thereof a recess for receiving the pipes. The base component and the counter element are connectable through at least one pivot joint and at least one locking member. At least one hydraulic drive is provided for positioning the counter element relative to the base component. A mechanical locking device in addition to the closing member connects the base component and the counter element with each other.
