Problems solved by technology

[0002] In the process of nuclear waste disposal, due to the high radioactivity of nuclear waste, ordinary cranes are difficult to use for a long time in such a highly radioactive environment
Because the driving mechanism that drives the cart and the mobile trolley in the existing cranes is set on the beam, and when working in a high-radiation working environment for a long time, the electrical actuators in the driving mechanism will have aging and failure rates. For the maintenance of the driving mechanism, maintenance workers need to enter a highly radioactive environment to operate the driving mechanism, which may easily cause the maintenance workers to be exposed to radiation.

Abstract

The present invention relates to a crane used in a highly radioactive environment. The crane comprises a crossbeam, and traveling wheels disposed under two ends of the crossbeam to drive the crossbeam to travel. A moving trolley capable of reciprocating motion on the crossbeam is disposed on the crossbeam. A direction of motion of the crossbeam is perpendicular to a direction of motion of the moving trolley. The crane further comprises a first driving mechanism, a second driving mechanism having the same structure as the first driving mechanism, and a transmission mechanism that transfers the driving force of the first driving mechanism and the second driving mechanism to the moving trolley. The first driving mechanism comprises a driving motor, a front-end sprocket wheel and a tail-end sprocket wheel that are not disposed on the crossbeam, and a transmission sprocket wheel case that is disposed on the crossbeam. The front-end sprocket wheel is connected to a power output end of the driving motor. The front-end sprocket wheel, the sprocket wheel in the transmission sprocket wheel case, and the tail-end sprocket wheel are in transmission connection with one another by means of a chain. According to the present invention, the driving mechanisms in the crane can be prevented from highly radioactive pollution, thereby prolonging the service life of the crane and also facilitating later maintenance.

Description

technical field [0001] The invention relates to a crane used in a high radiation environment. Background technique [0002] In the process of nuclear waste disposal, due to the high radioactivity of nuclear waste, ordinary cranes are difficult to use for a long time in such a highly radioactive environment. Because the driving mechanism that drives the cart and the mobile trolley in the existing cranes is set on the beam, and when working in a high-radiation working environment for a long time, the electrical actuators in the driving mechanism will have aging and failure rates. The driving mechanism is installed on the beam, and the later maintenance of the driving mechanism requires maintenance workers to enter a highly radioactive environment to operate the driving mechanism, which may easily cause the maintenance workers to be exposed to radiation. Contents of the invention [0003] In view of the above technical problems, the present invention provides a crane with a ...
