Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] combine Figure 1 to Figure 8 , an underwater pipeline clamping and crawling device of the present invention includes an integral frame 10 , a clamping device 200 , and a crawler crawling device 300 .

[0020] The clamping device 200 is mainly composed of a middle clamping mechanism 210 , a left clamping mechanism 220 , a right clamping mechanism 230 and a clamping transmission mechanism installed on the overall frame 10 . The clamping device is in a loose state before the machine is placed in the working position, and the distance between the left and right sets of clamping mechanisms is greater than the diameter of the pipe to be clamped, so that the machine can be placed in a suitable position on the pipe.

[0021] The middle clamping mechanism 210 is mainly composed of a clamping drive hydraulic motor 211, a meshing bevel ...

Abstract

The invention provides an underwater pipeline clamping and crawling machine which comprises a whole framework, a clamping device and a caterpillar crawling device. The working principle is that the underwater pipeline clamping and crawling machine is placed in the proper place of a pipeline with outside assistance, a hydraulic motor is clamped and driven to provide power so that three sets of caterpillar bands to clamp the pipeline synchronously, and a hydraulic motor in the caterpillar crawling device can provide power to complete crawling movement while clamping. The underwater pipeline clamping and crawling machine can solve the problems of self-centering clamping and crawling of a submarine pipeline, and the efficiency of working on the underwater pipeline is improved.

Description

technical field [0001] The invention relates to an underwater pipeline clamping and crawling tool, which is suitable for the tasks of self-centering clamping and crawling of underwater pipelines, and is an important equipment for underwater operations. Background technique [0002] With the continuous progress of my country's offshore oil and gas development, oil and gas production is also increasing year by year, and the requirements for marine resource development technology are also becoming higher. Therefore, the exploitation of underwater oil and gas has become an important direction for the development of marine energy in my country, and its exploitation technology has also become a key research object. In the exploitation of underwater oil and gas, the regular safety inspection of the outer surface of the underwater pipeline, the cleaning of marine organisms and the maintenance of the pipeline all need to clamp the underwater pipeline, and due to the particularity of ...
