Problems solved by technology

[0003] The single-piece bolt screwing and stretching mechanism needs to be installed repeatedly during use, and the bolts need to be screwed and stretched one by one. It will take a long time to install and use, and waste manpower and material resources. At the same time, it is impossible to guarantee that all bolts will Even by force;
[0004] Due to its large size and weight, the integral bolt screwing and tensioning mechanism needs to be hoisted with a heavy-duty bridge jack, and it is difficult to correct the position, resulting in time-consuming and laborious installation. Restricted use of integral bolt-twisting tensioning mechanisms

Abstract

The invention discloses a sectioning type integral full-synchronous bolt screwing and stretching mechanism, and belongs to the technical field of screwing and stretching of nuclear power reactor pressure vessel bolts. According to the scheme, the sectioning type integral full-synchronous bolt screwing and stretching mechanism comprises bolt adapters, a c-shaped support, a b-shaped support, an a-shaped support, a plurality of bolt storage racks, bolts, a robot used for screwing the bolts, a screwing sectioning type full-synchronous bolt stretching machine used for bolt stretching, bolt elongation measurement and a main nut, and a control console; each bolt storage rack is provided with the c-shaped support or the b-shaped support or the a-shaped support; and each of the c-shaped support, the b-shaped support and the a-shaped support is provided with the plurality of bolts, each bolt is connected with one bolt adapter, and the control console is connected with the screwing sectioning type full-synchronous bolt stretching machine. The sectioning type integral full-synchronous bolt screwing and stretching mechanism has the beneficial effects that the whole full-synchronous bolt screwing and stretching mechanism is formed by installing a sectioning type mechanism, and due to the small size and the light weight of the sectioning type integral full-synchronous bolt screwing and stretching mechanism, installation is more convenient and faster, time and labor are saved, and the sectioning type integral full-synchronous bolt screwing and stretching mechanism is particularly suitablefor occasions with limited installation space.

Description

technical field [0001] The invention belongs to the technical field of screwing and stretching of nuclear power reactor pressure vessel bolts, and in particular relates to a split-type integral fully synchronous bolt screwing and stretching mechanism. Background technique [0002] At present, what are used in the aspect of bolt twisting and stretching of nuclear power reactor pressure vessels are single bolt twisting and stretching mechanisms and integral bolt twisting and stretching mechanisms. However, the current nuclear reactor pressure vessel bolt screwing and stretching mechanism has the following problems: [0003] The single-piece bolt screwing and stretching mechanism needs to be installed repeatedly during use, and the bolts need to be screwed and stretched one by one. It will take a long time to install and use, and waste manpower and material resources. At the same time, it is impossible to guarantee that all bolts will Even by force; [0004] Due to its large ...
