Description

Radiation-proof lifting appliance

Technical Field

The utility model relates to an environmental protection equipment field, concretely relates to radiation protection hoist.

Background

With the wide application of radioactive energy in the fields of medical treatment, seed cultivation, precious metal identification and the like, a plurality of radioactive pollution sources, namely radiation waste sources, are accumulated around people. In the 80 s of the past century, the state establishes a radiation waste source management station and a corresponding radiation waste source recycling transfer warehouse in environment-friendly halls of provinces and cities. These radioactive sources are supervised by specialists and effectively recovered and reasonably stored.

At present, the processes of loading, hoisting and retrieving the waste source in the radiation waste source warehouse are all implemented by manual operation of environmental management personnel, even if workers wear thick protective clothing and hang heavy lead plates, a plurality of workers suffer from occupational diseases caused by radiation, the loading efficiency is extremely low, the original operation method sometimes causes that the waste source falls into the warehouse and cannot be retrieved, and permanent pollution is caused to the warehouse and the surrounding environment. Therefore, the automatic design of the equipment is urgently needed. After the project is finished, the automatic control system is adopted to finish the processes of shipping, lifting, retrieving and the like, so that hidden dangers are fundamentally eliminated and the safety is improved.

Disclosure of Invention

An object of the utility model is to solve the not enough of prior art existence, provide a radiation protection hoist, simple structure is practical, but remote control accomplishes the shipment of the useless source of radiation, lifts by crane and retrieves, reduces the radiation to personnel and falls of useless source, improves the security of work, improves work efficiency.

The utility model adopts the technical proposal that: a radiation protection lifting appliance comprises an installation hanger 1, a driving gear motor 2, a sliding seat 3, a crank rotating disc 4, a connecting rod 5, a sliding hook 6 and a lifting bolt 7, wherein the installation hanger 1 is a square frame-shaped integral component formed by welding a plurality of square steels, a rolling bearing 11 is arranged in the middle of the installation hanger 1, four sliding seats 3 are uniformly arranged below the centers of four edges of the installation hanger 1, the crank rotating disc 4 is arranged below the installation hanger 1 and comprises a crank disc 41 and a rotating connecting shaft 42, the rotating connecting shaft 42 is arranged in the middle of the crank disc 41, four connecting holes 43 are uniformly arranged on the crank disc 41, the rotating connecting shaft 42 is arranged in an inner hole of the rolling bearing 11, the driving gear motor 2 is fixedly arranged on the installation hanger 1, an output shaft of the driving gear motor is connected with the rotating connecting shaft 42, the sliding hook 6 is in an L shape and comprises a sliding connecting rod 61 and a hook arm 62, the sliding connecting rod 61 is inserted into the sliding seat 3, a sliding bearing is arranged between the sliding seat and the sliding connecting rod, the lower end of the hook arm 62 is provided with a hook head 63, the hook head 63 faces the direction of the sliding connecting rod 61, the connecting rod 5 is arranged between the crank rotating disc 4 and the sliding hook 6, the two ends of the connecting rod are respectively hinged with the connecting hole 43 and the rear end of the sliding connecting rod 61, and four lifting ring screws 7 are uniformly arranged at four corners of the mounting hanger 1.

Compared with the prior art, the utility model following beneficial effect has: simple structure is practical, but remote control accomplishes shipment, the lift by crane and the retrieval of the useless source of radiation, reduces the radiation and the falling of useless source to personnel, improves the security of work, improves work efficiency.
