Description

Technical Field

[0001] The utility model relates to the technical field of steel barrel transfer equipment, in particular to a radioactive waste barrel lifting device. Background Art

[0002] When working with radioactive materials, workers often need to wear special labor protection. After reaching the end of their service life, these labor protections need to be sent to special treatment agencies for a series of treatment measures such as sorting, gasification cracking, solidification and landfill. During transportation, special specifications of radioactive waste barrels are required. These radioactive waste barrels have thick walls and are therefore often very heavy. Currently, special clamping vehicles are used for clamping and transportation. After the radioactive waste barrels have been exposed to this clamping equipment many times, the outer barrel walls will be damaged by paint peeling, scratches, etc. Over time, the labels will become unclear. In addition, when stacking, the clamping vehicles often have limitations such as stacking height and radioactive waste barrels of different specifications. They are not very convenient to use, so improvements need to be made to the radioactive waste barrels. Utility Model Content

[0003] In view of the above technical problems, the utility model provides a radioactive waste barrel lifting device which will not cause damage to the barrel wall and is more convenient to use.

[0004] In order to solve the above technical problems, the utility model discloses a radioactive waste barrel lifting device, comprising a bracket, which is cross-shaped and has a plurality of through holes. Four branches of the bracket are connected with a first D-shaped shackle through the through holes, a circular chain is connected below the first D-shaped shackle, a second D-shaped shackle is connected below the circular chain, a caliper is connected below the second D-shaped shackle, and a lifting buckle is fixedly connected to the center of the upper part of the bracket.

[0005] Furthermore, a reinforcement plate is fixedly connected between the branches of the bracket.

[0006] Furthermore, the caliper is composed of a caliper tongue and a caliper body. The caliper tongue is hinged to the caliper body. The lower part of the caliper tongue has a protruding structure. The corresponding parts of the caliper body and the caliper tongue have anti-slip grooves.

[0007] Compared with the prior art, the utility model has the following advantages:

[0008] The utility model can easily lift the radioactive waste barrel by clamping the barrel cover and the barrel flange connection position above the radioactive waste barrel by calipers, and the operation of clamping and removing is simple and convenient, and no damage is caused to the barrel wall. In conjunction with the gantry crane, the radioactive waste barrels can be quickly stacked without being affected by the height, and different installation positions of the first D-type shackle can adapt to radioactive waste barrels of different specifications and sizes.

[0013] The utility model will be further described below in conjunction with the accompanying drawings.

[0014] like Figures 1 to 3 A radioactive waste barrel lifting device shown in the figure includes a bracket 1, which is in a cross shape. Each branch of the bracket 1 is provided with three through holes. The outermost through hole of each branch of the bracket 1 is connected to a first D-type shackle 2, a circular chain 3 is connected below the first D-type shackle 2, a second D-type shackle 4 is connected below the circular chain 3, a caliper 5 is connected below the second D-type shackle 4, a lifting buckle 6 is fixedly connected to the center above the bracket 1, and the devices are covered with an anti-corrosion coating.

[0015] In order to increase the connection stability of the bracket 1 , a reinforcing plate 7 is fixedly connected between the branches of the bracket 1 .

[0016] In order to increase the friction between the caliper and the radioactive waste barrel and increase the lifting stability, the caliper 5 is divided into a caliper tongue 501 and a caliper body 502. The caliper tongue 501 is hinged to the caliper body 502. A protruding structure is arranged at the lower part of the caliper tongue 501. Anti-slip grooves are also arranged on the corresponding parts of the caliper body 502 and the caliper tongue 501.

[0017] The working process of this embodiment is as follows:

[0018] When in use, the hook of the gantry crane is hung on the lifting buckle 6, and after the gantry crane is adjusted to a suitable height, the caliper 5 is clamped at the flange connection position of the barrel cover and barrel body of the radioactive waste barrel 8, so that the protruding structure of the clamp tongue 501 and the anti-slip groove of the clamp body 502 stably contact the flange plate, and the gantry crane can be operated to lift, transport, stack, etc. the radioactive waste barrel 8. After placing it at the designated position, the height of the gantry crane is lowered to make the ring chain 3 in a relaxed state, and the caliper 5 can be easily removed. The operation is convenient and fast, and will not cause damage to the barrel wall. When facing radioactive waste barrels 8 of different specifications, by adjusting the position of the first D-type shackle 2 on the through hole of the bracket 1, it can adapt to radioactive waste barrels 8 of different sizes, and the reinforcing plate 7 can increase the connection stability of the bracket 1, which is safer.
