A Shearing Device Convenient for Remote Maintenance

Abstract

The invention relates to a shearing device convenient to repair in a long distance. The shearing device consists of three repair modules, a fixed part and a table plane, wherein the fixed part consists of a bottom plate, discharge openings, positioning pins, pressing plates, and cone point screws, wherein the discharge opening and the positioning pins are fixed in / on the bottom plate; the bottom plate is fixed on the table plane through the pressing plates and the cone point screws; the discharge opening can be connected with a subsequent material receiving device; the three repair modules are respectively a driving module, a cutter module and a shearing chamber module, and are divided according to different repair frequencies of components and parts; the three repair modules can be independently mounted or demounted, and can also be together mounted or demounted, so that the phenomenon that because consumables or parts which are liable to be damaged need to be frequently repaired, the whole equipment needs to be hoisted away to repair every time is avoided. According to the shearing device disclosed by the invention, through the modular design, the repair efficiency is improved; the structure is convenient for long-distance repair, and is simple and reliable.

Description

technical field [0001] The invention belongs to a small shearing device which is convenient for remote maintenance. It is mainly used to complete the task of cutting a single spent fuel element into segments. Background technique [0002] In the field of nuclear chemical industry, the production and processing of radioactive substances are usually carried out in sealed chambers. Because the materials or equipment in the chamber are toxic or radioactive, personnel cannot directly perform maintenance operations such as disassembly and replacement of the equipment in the chamber, and can only use remote operation tools (such as cranes, manipulators, special tools, etc.) Perform remote maintenance. Because the distance, range, means, degree of freedom and flexibility of the operation are all greatly restricted, thereby bringing great difficulties to the maintenance work, even impossible to maintain. This just requires that the equipment in the box room should meet the design ...

AI Technical Summary

Problems solved by technology

Because the materials or equipment in the chamber are toxic or radioactive, personnel cannot directly perform maintenance operations such as disassembly and replacement of the equipment in the chamber, and can only use remote operation tools (such as cranes, manipulators, special tools, etc.) Carry out remote maintenance

Since the distance, range, means, degree of freedom and flexibility of the operation are greatly restricted, it brings great difficulties to the maintenance work, and even makes it impossible to maintain
