Cover taking and sealing system used for radioactive waste barrel

Abstract

The invention belongs to the field of nuclear chemical industry machinery equipment, and particularly relates to a cover taking and sealing system used for a radioactive waste barrel. The cover takingand sealing system is used for loosening and tightening operation on a top cover of the radioactive waste barrel placed on a transferring roller way near the inner side of a wall body; the cover taking and sealing system comprises a positioning device, a jacking-lifting device and a cover taking and sealing device, the positioning device and the jacking-lifting device are arranged on the wall body, and the positioning device is located above the transferring roller way, the jacking-lifting device is located below the transferring roller way, and the cover taking and sealing device is arrangedabove the jacking-lifting device and the transferring roller way; and the positioning device can position the radioactive waste barrel on the transferring roller way, the jacking-lifting device can carry out lifting operation to the positioned radioactive waste barrel, and cover taking and sealing system can go down and carry out operation of loosening or tightening the jacked top cover of the radioactive waste barrel. The cover taking and sealing system has the advantages of being simple in structure, reliable in movement, low in failure rate, easy to maintain and low in cost and can be controlled remotely, radiation harm of staff is reduced, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of nuclear chemical machinery and equipment, and in particular relates to a cap removing and capping system for radioactive waste barrels. Background technique [0002] In the field of nuclear chemical industry, 400L steel drum (called radioactive waste drum in this paper) is a widely used container, which is often used as radioactive waste drum. The bung of the 400L steel drum and the flange of the steel drum are fastened by bolts. Due to the danger of radioactive waste, it is often impossible for the operator to manually loosen and tighten the bolts on the lid of the barrel at close range. Therefore, it is necessary to design a new type of cap removal system to realize remote monitoring of the lid of the radioactive waste barrel. The bolts are loosened and tightened. Contents of the invention [0003] Aiming at the needs of loosening and tightening the bolts on the lid of the radioactive waste barrel, the purpose...
