Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] The supporting roller mechanism of the present invention is mainly aimed at a large-sized disc-shaped part similar to a waterwheel, which is immersed in a strong radioactive environment and rotates at a relatively low speed.

[0023] Such as figure 2 As shown, the supporting roller of the present invention is composed of a roller main body 5, an upper buckle 6, a lower buckle 8, a locking pin 7, a turning block 9 and a roller 11. The main body of the roller is divided into three sections, the front end is a cylindrical stick front end 16, the middle is a cylindrical stick middle part 17, and the tail end is a conical stick tail end 18. Roller main body front end is used for installing the roller 11 that can rotate flexibly, as image 3 As shown, the roller is fixedly installed on the front end of the roller main body 5 through a bearing 15 ,...

Abstract

The invention relates to a long-distance rapid replacing type supporting roller mechanism, and specifically relates to a long-distance rapid replacing type supporting roller mechanism which is suitably used for supporting a disc shaped part soaked in high-radioactive liquid. The supporting roller mechanism comprises a plurality of roller bodies which are symmetrically mounted like an arc on a mounting plate, wherein each roller body comprises a front end, a medium end and a tail end; a flexible rotating roller is mounted at each front end and used for supporting the disc shaped part; each tail end passes through a circular hole in the mounting plate and is fixed to the mounting plate through a locking assembly. With the adoption of the supporting roller mechanism, the disc shaped part can be reliably supported, and moreover, the long-distance maintenance, overhaul and replacement can be conveniently and quickly performed for the disc shaped part through a manipulator or a power hand.

Description

technical field [0001] The invention relates to a support roller mechanism that can be quickly replaced at a long distance, in particular to a support roller mechanism that can be quickly replaced at a long distance and is suitable for supporting a disc-shaped component immersed in a strong radioactive liquid. Background technique [0002] Usually, for mechanical parts that do rotary motion, such as steam turbine rotors, the installation adopts the method of "fixed central shaft and supported by bearings". If the rotating part is in a fluid medium environment, the necessary fluid sealing structure is often provided on the shaft. If the fluid medium is highly radioactive, the sealing performance, reliability and service life of the fluid sealing structure will be severely tested. In a highly radioactive environment, since humans cannot directly participate, it is extremely difficult to perform remote maintenance, repair, and replacement of bearings and sealing structures thr...
