Abstract

The invention discloses a pile fixing system for a self-elevating ocean platform and belongs to the field of marine engineering equipment. The pile fixing system comprises a hydraulic power source, a two-position three-way reversing valve and a plurality of pile fixing devices. Each pile fixing device comprises a hydraulic oil cylinder, a fixing assembly and a supporting frame. An oil outlet of the hydraulic power source is communicated with a first oil opening of the two-position three-way reversing valve. A second oil opening of the two-position three-way reversing valve is communicated with rodless cavities of the multiple hydraulic oil cylinders. A third oil opening of the two-position three-way reversing valve is communicated with rod cavities of the multiple hydraulic oil cylinders. According to the embodiment, the pile fixing system comprises the multiple pile fixing devices, and all the pile fixing devices control jacking force of the pile fixing system through piston rods of the hydraulic oil cylinders, and thus the pile fixing function is achieved through the jacking force provided by the multiple pile fixing devices.

Description

technical field [0001] The invention relates to the field of ocean engineering equipment, in particular to a pile fixing system for a self-elevating ocean platform. Background technique [0002] The self-elevating offshore platform is a movable platform in the sea, which is mainly composed of a platform hull, legs and lifting devices. [0003] Existing self-elevating offshore platforms need pile-fixing devices to fix pile legs under the working conditions of moving or standing. The pile-fixing frame of the device needs to be provided with a wedge-shaped structure matched with the structure of the pile-fixing block for placing the pile-fixing block. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] As the load of the self-elevating offshore platform increases, the weight and quantity of the pile blocks will increase. Generally, the weight of a single pile block will reach ...
