Description

Technical Field

[0001] The invention belongs to the technical field of mechanical design, and in particular relates to a cover removing device for an embedded steel barrel. Background Art

[0002] In order to reduce the production of radioactive waste, nuclear power plants use centralized and efficient treatment methods to treat radioactive waste. In the process of radioactive waste treatment, radioactive waste needs to be placed in a compressible steel barrel, and then the barrel and waste are super compressed into barrel cakes, which are then placed in a 200L steel barrel, fixed with cement, and sealed to form a complete waste package.

[0003] When loading waste into compressible steel drums, the drum lid needs to be removed. Since the drum lid and drum body of the compressible steel drum used on site are a combination of embedded structures, the drum lid is embedded in the steel drum using its own structural characteristics and the elastic characteristics of cast iron material. The compressible steel drum is not equipped with a special lid removal tool, so in the absence of suitable tools, it is necessary to use pliers to twist and steel rods to pry, which is not only time-consuming and laborious, but also has the risk of damaging the drum lid structure. In addition, in actual production, 15 compressible steel drum lids need to be removed at one time, and the lid removal work has brought great inconvenience to production. Summary of the invention

[0007] The bayonet connecting rod, the fixed bayonet and the fixed handle are fixed parts, and the movable handle and the movable bayonet are movable parts.

[0008] It also includes a distance adjusting slide groove, and the distance adjusting slide groove is opened on the rod body of the bayonet connecting rod close to the fixed handle.

[0009] The movable handle is provided with a through hole on the right-angle side of the movable bayonet.

[0010] It also includes a connecting pin, which passes through the through hole and the distance-adjusting sliding groove on the bayonet connecting rod to connect the bayonet connecting rod and the movable handle.

[0011] The movable handle can move along the bayonet connecting rod.

[0012] There are two movable bayonet sockets, which are symmetrical about the center of the movable handle and are respectively located on both sides of the bayonet connecting rod.

[0013] When the barrel cover needs to be removed, first place the movable handle and the movable bayonet in the dotted line position, place the cover removal device in the center line position on the barrel cover, make the fixed bayonet and the movable bayonet located on both sides of the barrel cover symmetrical with the center point of the barrel cover, operate the movable handle to press it toward the fixed handle to the solid line position, make the fixed bayonet and the movable bayonet fasten the barrel cover, then lift the fixed handle upwards, separate the barrel cover from the barrel body, and move the whole to the barrel cover storage position, loosen the movable handle and the fixed handle, and separate the barrel cover from the cover removal device.
