Description

technical field [0001] The invention relates to the technical field of pipeline detection and walking equipment, in particular to a 35mm-37mm artillery barrel detection and walking device. Background technique [0002] In daily production and life, pipelines are an important means of material transportation, with a wide range of applications and numerous types and quantities. According to different use environments, due to corrosion, high temperature, high pressure, etc., some pipelines have cracks, scratches, defects, perforations, etc., which seriously affect the order of production and life. Therefore, the pipeline must be regularly repaired. Factors such as the environment and the shape and size of the pipeline make it difficult for people to reach directly, but it is also impossible to carry out excavation testing, so maintenance is very difficult. Especially for small-diameter pipes, due to the small inner diameter, if you want to enter the interior, you must require ...

The third is to use SMA spring instead of the motor screw mechanism to drive. This method has a simple structure, but the SMA spring responds slowly and consumes a lot of power.

The fourth type uses a flexible flexible shaft screw drive mechanism. The screw drive mechanism is composed of a hollow motor shaft and a flexible shaft. The hollow motor shaft has an internal thread that matches the structure of the flexible shaft. Composition, this method has high requirements on materials, and the drive efficiency is lower than that of hard shafts

The fifth type adopts electromagnetic drive, which is divided into front and rear sections in structure, connected by a spring in the middle, the coil is fixed with the front section, and legs are installed on the front and back sections. The lock function prevents the previous section from moving backwards. Under the action of electromagnetic attraction, the latter section moves forward. When the coil is powered off, the backward section also has a one-way self-locking function, so that the rear section cannot move backwards. Under the action of the spring force, the previous section is ejected forward for a certain displacement. This method has short transmission links, fast movement speed, and large traction force. The disadvantage is that it cannot move at a uniform speed, the vibration is also large, and the friction force is large.

[0010] The snake form is a high-redundancy system composed of multiple joint modules. The connection modes between each joint mainly include parallel connection, orthogonal connection and universal connection. The axis of the rotating pair between the joint modules connected in parallel Parallel to each other, this kind of robot can realize two-dimensional motion in the plane; the axes of the rotation pairs between two adjacent joints that adopt orthogonal connection are perpendicular to each other, this kind of robot can realize three-dimensional motion; the joints that adopt universal connection can realize Rotation in any direction, this kind of robot movement is more flexible, but the mechanical structure is also quite complicated

Snake form is suitable for plane sports, climbing sports and underwater sports, and can also be used in pipelines, but its motion control method is complicated, and no breakthrough has been made so far
