Problems solved by technology

At present, on-site detection of surface defects and hidden dangers of pile legs mainly relies on methods such as manual crawling and naked eye observation. This method is usually accompanied by high-altitude operations, which is difficult to operate, low in efficiency, and has certain dangers, and the detection range is limited.
[0003] The present invention is based on the internal structure of dry-type pile legs of an offshore platform. The inner cylindrical space of the pile leg is divided into two semi-cylindrical parts, and one of the semi-cylindrical spaces is equipped with multi-layer working platforms, ladders, guardrails and other structures, and the structure is relatively complicated. , not suitable for robot crawling

Embodiment Construction

[0040] The invention develops a robot that can reciprocate and crawl in the semicircular space inside the legs of the offshore platform. The robot adopts a step-by-step crawling method, and can cross the protruding obstacles in front of the crawling. In order to further understand the content, characteristics and effects of the present invention, combine Figure 1-22 , hereby exemplify the following embodiments, and describe in detail as follows:

[0041] The robot (A) is composed of an upper leg group (A1), a torso (A2), and a lower leg group (A2). The upper leg group (A1) and torso (A2) of the robot (A) are connected as a whole through the leg bottom plate (7) and the main slider seat (14), and the leg bottom plate (7) is fixed on the main slider seat (14) by bolts on the top plane. The lower leg group (A3) and torso (A2) of the robot (A) are connected as a whole through the leg bottom plate (7) and the leg-trunk connecting seat (8), and the leg bottom plate (7) is fixed ...

Abstract

The invention belongs to the technical field of specialized robots, and discloses an offshore platform pile leg half-round inner wall crawling robot. The offshore platform pile leg half-round inner wall crawling robot is composed of an upper leg group, a body and a lower leg group. The upper leg group of the robot is integrally connected with the body through a main sliding block seat and a leg bottom plate, and the leg bottom plate is fixed to the top plane of the main sliding block seat through bolts. The lower leg group is integrally connected with the body through a leg bottom plate and aleg-body connecting seat, the leg bottom plate is fixed to the top plane of the leg-body connecting seat through bolts. The offshore platform pile leg half-round inner wall crawling robot can carry detection or operation equipment to carry out defect detection or specific operation on the inner wall of a pile leg.

Description

technical field [0001] The invention relates to a crawling robot on the semicircular inner wall of pile legs of an offshore platform, which belongs to the field of mechanical design. Background technique [0002] The pile leg is an important basic component to maintain the stability and safety of the offshore platform. At present, on-site detection of surface defects and hidden dangers of pile legs mainly relies on methods such as manual crawling and naked eye observation. This method is usually accompanied by high-altitude operations, which is difficult to operate, low in efficiency, and has certain risks. The detectable range is limited. [0003] The present invention is based on the internal structure of dry-type pile legs of an offshore platform. The inner cylindrical space of the pile leg is divided into two semi-cylindrical parts, and one of the semi-cylindrical spaces is equipped with multi-layer working platforms, ladders, guardrails and other structures, and the str...
