摘要： A load compensator (80, 190, 200) includes one or more tension spring assemblies (96, 97) that are contained within a tubular housing (100, 205) when tension from a load is applied to the tension spring assemblies (96, 97). The housing further contains a crush pad (185) which is crushed by the elongation of a tension spring assembly (96, 97) when tension applied from the load exceeds a threshold. When the load compensator (80, 190, 200) includes more than one tension spring assembly (96, 97), the tension spring assemblies (96, 97) are mechanically connected to each other in series and stacked in-line with each other in the housing (100, 205). In a preferred construction, each of the tension spring assemblies (96, 97) includes elastomeric tension elements (120, 142, 153, 156) mounted between two plates (130, 143, 151, 152, 154, 155).

摘要： A crane includes a base, an upperstructure rotationally mounted on the base, a boom pivotally mounted to the upperstructure at a front attachment location and having a distal end supporting a load line for raising a payload, and a gantry mounted on the upperstructure and supporting a boom line coupled to the distal end of the boom. The gantry includes at least one front leg mechanically coupled to the front attachment location and inclined in a direction away from the boom to apply, to the front attachment location, a horizontal force component towards the boom that is opposed by a horizontal force component applied by the boom towards the front leg. The upperstructure includes a circular turret, and the front attachment location is aligned over a circle of the turret.

摘要： A composite elastomeric flexible element has an elastomer layer between rigid members. When subjected to loads, and as time goes by, the elastomer layer will undergo damage in the form of micro-voids and polymer chain scission. The time it takes the damage to reach a predetermined, but safe state is a known function of several parameters such as loading rate and load magnitude, time at load, temperature and frequency. The damage decreases the electrical permittivity of the elastomer and changes the electrical conductance of the elastomer if the elastomer is in the environment of an electrically conductive fluid or when the elastomer includes conductive filler. The health of the flexible element is monitored by measuring the electrical impedance of the elastomer layer, computing an indication of health from the electrical impedance and trend data for the elastomer layer, and reporting the indication of health to a human administrator.

摘要： A telescopic joint for a marine drilling riser has an outer barrel and an inner barrel defining a central lumen for passage of a drill pipe string. The inner barrel is received within the outer barrel, and there is a clearance fit between the barrels for sliding of the inner barrel with respect to the outer barrel while maintaining a coaxial relationship between the barrels. A tubular rolling elastomeric membrane is disposed within the outer barrel and has one end secured to an outer circumference of the inner barrel and another end secured to an inner circumference of the outer barrel for sealing drilling fluid within the central lumen. As the inner barrel slides with respect to the outer barrel, the elastomeric membrane rolls with respect to the inner barrel and the outer barrel so that wear of the seal due to abrasion is eliminated.

摘要： The present invention provides, for load compensation, different kinds of elastomeric load compensators placed at various locations on the crane for increased flexibility and for shock and vibration absorption. The elastomeric load compensators employ elastomeric tension elements, elastomeric torsion elements, or elastomeric shear elements. Elastomeric tension elements can be simply inserted in series with the main hoist rope. An elastomeric load compensator employing elastomeric torsion elements is mounted to the underside of the boom for receiving the live end of the main hoist rope. A single stack of elastomeric shear elements is suitable for mounting a hoist or winch or an idler sheave to the crane structure. For additional load compensation, the hoist, winch, and idler sheaves are mounted on rails for increased displacements under heave loads, and the increased displacements are compensated by elongated elastomeric tension elements or multiple elastomeric tension, torsion or shear elements in series.
