Problems solved by technology

However, there are still many problems in the traditional cantilever beam moving device. For example, the structure of the traditional cantilever beam moving device is relatively complicated, its production cost is high, and its moving speed is slow. It is also difficult to control the synchronous movement of the cantilever beam moving device or accurately adjust the cantilever beam position etc.

Abstract

The invention provides a cantilever beam moving device for a self-elevating petroleum drilling platform. The device comprises two reversing handles, two pawl assemblies, connecting pins, two hydraulic oil cylinders and an oil cylinder base, wherein the two reversing handles are correspondingly assembled on the two pawl assemblies; the two hydraulic oil cylinders are respectively arranged at the left and right ends of the oil cylinder base; one ends of the two hydraulic oil cylinders are respectively connected with the left and right ends of the oil cylinder base by the connecting pins; and the other ends of the two hydraulic oil cylinders are respectively correspondingly connected with the two pawl assemblies by the connecting pins. After adopting the above scheme, the device can move quickly, has low production cost and is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of jack-up drilling platform equipment, in particular to a cantilever beam moving device of a jack-up oil drilling platform. Background technique [0002] Generally, the cantilever beam moving device is suitable for a jack-up drilling platform, and is used to push the cantilever beam to move longitudinally along the hull as required and maintain the position when operating at sea. However, there are still many problems in the traditional cantilever beam moving device. For example, the structure of the traditional cantilever beam moving device is relatively complicated, its production cost is high, and its moving speed is slow. It is also difficult to control the synchronous movement of the cantilever beam moving device or accurately adjust the cantilever The position of the beam and so on. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior a...
