Problems solved by technology

Although the automatic cap removal method for steel drums is mature, due to the need to install a large number of electric tightening devices, each tightening device needs to be equipped with a parameter detection and torque control unit, resulting in high cost for the automatic cap removal device and many electric and control components. There is also a hidden danger of high failure rate; on the other hand, the method that a special bolt of the steel drum needs to be equipped with a set of electric tightening device requires high precision in the position of the bolt holes on the cover plate of the steel drum and the drum body, resulting in this The traditional automatic capping method is difficult to apply to large-sized radioactive waste packaging containers, such as steel boxes

Abstract

The invention provides a packaging container, an automatic cover taking and sealing device and an automatic cover taking and sealing system and method.The packaging container comprises a container body and a cover body, the cover body comprises a cover plate, a rotary table and a driven mechanism, the rotary table is rotationally connected to the center of the upper surface of the cover plate, one end of the driven mechanism is hinged to the edge of the rotary table, and the other end of the driven mechanism is provided with a first connecting part; the container body is provided with a second connecting part matched with the first connecting part, when the rotary table rotates, the rotary table can drive the driven mechanism to rotate around the hinge point of the driven mechanism, so that the other end of the driven mechanism is close to or away from the rotary table, and when the other end of the driven mechanism is away from the rotary table, the driven mechanism is driven to rotate. When one end of the driven mechanism is close to the rotary table, the driven mechanism drives the first connecting part to move towards the second connecting part to be connected with the second connecting part, and when the other end of the driven mechanism is close to the rotary table, the first connecting part is driven to release connection with the second connecting part. The automatic cover taking and sealing structure of the radioactive waste packaging container is simplified to a large extent, the equipment reliability is improved, and the equipment cost is reduced.

Description

technical field [0001] The present invention specifically relates to a packaging container, an automatic capping device, an automatic capping system and method. Background technique [0002] In the process of radioactive waste treatment in nuclear power plants or nuclear facilities, it is often necessary to pack the radioactive waste into packaging containers through a certain treatment process. In order to avoid radiation damage to the operator, the operator cannot approach the packaging container, and the capping and capping operations of the packaging container need to be realized by remote automatic control. Commonly used radioactive waste packaging containers include steel boxes and steel drums. Steel boxes are mostly used for secondary packaging, especially for large-sized steel boxes. Currently, there is no method and device for automatically taking caps; Mature, it mainly adopts the solution of evenly distributing special bolts on the same distribution circle to rea...
