An anti-detachment and tensile end structure of a fiberglass tie rod

Abstract

In order to solve the technical problems that the thread of the existing FRP tie rod end structure is easily crushed and damaged when it is subjected to high pressure and repeated disassembly, and the relative sliding or direct pull-off between the end and the tie rod is easy to occur when the end is subjected to a large tensile force. The invention provides an anti-slip anti-stretch end structure of a FRP tie rod, which includes a round platform formed by cutting the two ends of the FRP tie rod, and an anti-slip tensile assembly arranged on the round platform; The lower bottom surface is the end face of the FRP tie rod, and the diameter of the lower bottom surface is equal to the diameter of the FRP tie rod; the cone angle of the circular table is 1-5°; the anti-stripping assembly includes an inner fastening hoop and an outer fastening sleeve hoop; the inner fastening hoop is set outside the round table for wrapping and holding the side of the round table; the outer fastening hoop is set outside the inner fastening hoop for wrapping and holding tightly The outer side wall of the inner fastening ferrule.

Description

technical field [0001] The invention belongs to the technical field of research and development of high-voltage pulse equipment, and particularly relates to an anti-separation and tensile end structure of a glass fiber reinforced plastic tie rod. Background technique [0002] In the megavolt-level fully gas-insulated high-voltage pulse equipment, in order to obtain a higher amplitude and a faster leading edge for the output pulse voltage or current of the device, the charged main body is usually placed in a cavity filled with high-pressure insulating gas. In order to compress the structure as much as possible and facilitate the realization of the project, the multi-cavity structure in which the megavolt pulse equipment is nested layer by layer and the air pressure gradually increases from the outside to the inside is often used. The gas pressure inside the cavity can reach up to ten megapascals, and it also undertakes the structural support of the high-pressure components in...
