Abstract

The invention provides a cam loosening preventing mechanism applied to an underwater hoop connector. The cam loosening preventing mechanism comprises an upper fixing support, a lower fixing support, acam, a loosening preventing ROV bottom plate, an ROV wrench support and an ROV wrench, wherein the upper fixing support and the lower fixing support are arranged on a connector housing plate; the camis positioned between the upper fixing support and the lower fixing support; the loosening preventing ROV bottom plate is arranged above the upper fixing support; the ROV wrench support is arranged on the loosening preventing ROV bottom plate; the ROV wrench is arranged in the ROV wrench support; a middle shaft is arranged at the upper end of the cam and penetrates through the upper fixing support to be connected with the ROV wrench; two annular hole grooves are formed in the cam; loosening preventing pins are arranged in the annular hole grooves; pin holes are formed in the connector housingplate, and the tails of the loosening preventing pins are inserted into the pin holes; two double-end studs are further arranged between the upper fixing support and the lower fixing support; and twobosses with arc-shaped grooves are arranged on the side face of the cam. According to the cam loosening preventing mechanism, dual loosening preventing is achieved, the reliability of a project is guaranteed, and the quality of the project is improved.

Description

technical field [0001] The invention relates to an anti-loosening structure, in particular to a cam anti-loosening mechanism applied to an underwater hoop connector, and a composite cam anti-loosening structure applied to the hoop connector in an underwater environment. Background technique [0002] The three-lobed horizontal clamp connector relies on the double-headed stud to lock the three-lobed clamp. The close-in bolt itself has a certain self-locking ability. In order to prevent vibration from making the self-locking invalid and increase its reliability, it is necessary to It is anti-loose treatment. The existing thread has good self-locking performance due to its own structure, and is a commonly used fastening type anti-loosening and locking structure. However, threaded connections may be subjected to all types of variable loads during operation, including extremely severe vibration and shock loads, especially in subsea areas where earthquakes are common. Under the a...
