Problems solved by technology
However, considering the complex and changeable underwater environment, it is difficult for the pile clamp to clamp the steel pile at one time, and it needs to be repeatedly clamped and assisted in leveling. Therefore, a reliable control method is needed to operate the repetitive work of the pile clamp

Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings.
[0029] like Figure 1 to Figure 3 As shown, the present invention includes an outer casing 3 and an inner casing 5, a groove 4 between the inner and outer casings is left between the outer casing 3 and the inner casing 5, and a control wire is laid in the groove 4 between the inner and outer casings, leading to the upper component and the lower layer. Assemblies and mid-level assemblies for submerged assisted leveling and clamping operations. The top cover 1 is installed on the top of the outer casing 3, and the top cover 1 is provided with a slot 2 around it. The top cover 1 and the slot 2 are used for supporting and welding the guide ring, which is convenient for the penetration of the steel pile. Direct exposure to seawater reduces corrosion. A plurality of control boxes 10 are installed on the outer side of the outer casing 3 along its circumferential array, and ...

The invention discloses a pile clamp for jacket installation, comprising an outer casing and an inner casing, a plurality of control boxes are installed on the outer side of the outer casing along its circumferential direction, and the inner side of the inner casing is arranged along its height A plurality of baffles are installed in the direction, wherein, a plurality of clamping devices are arranged above the upper baffle and below the lower baffle, and the plurality of clamping devices are annularly arrayed along the circumferential direction of the inner shell, and the upper baffle and the lower baffle are arranged in a circular array. A middle-layer assembly is arranged between them, and the middle-layer assembly includes a plurality of compression devices arranged in a circular array along the circumference of the inner shell. An illumination device and an image collector are arranged between adjacent compression devices. The compression device is connected to the inner shell. There is a sensor in between, and a rolling ball is installed on the top of the compression device. The image collector of the invention provides the clamping and auxiliary leveling of the steel pile by the pile clamp. The underwater image is collected by the image collector, which can more conveniently observe the underwater working conditions, and is easy to realize information integration, and realizes computer integrated manufacturing. basic technology.
Description
technical field [0001] The invention relates to a pile clamp, in particular to a pile clamp for jacket installation. Background technique [0002] With the exploration and development of offshore oil and gas resources, the establishment of offshore platforms has received more and more attention. my country's large sea area, long coastline, and shallow water depth in offshore areas are very suitable for the construction and installation of jacket offshore platforms. [0003] Jacket platform, as an offshore multi-functional fixed platform, is mainly used for the development and processing of offshore oil and gas resources. The jacket platform has a high ultimate bearing capacity, and requires strong stability and bearing capacity during construction and installation at sea to cope with the influence of factors such as wind, waves and currents at sea. The form of the jacket is often affected by the arrangement of the pile foundation and the number of piles. In shallow sea are...
