Description
Technical Field
The invention relates to a material conveying mechanism, in particular to a shaft product transferring device.
Background
Among the major energy sources of today, nuclear power is the most specific one, and has been attracting attention since its appearance. Although the nuclear power technology in China is more mature, the post-treatment of nuclear fuel cannot be kept up with the post-treatment of nuclear fuel. When nuclear fuel can not be directly used any more, the replaced spent fuel needs to be subjected to aftertreatment to be solved, the spent fuel subjected to aftertreatment can be used in other modes, the aftertreatment of the spent fuel becomes an integral part of closed circulation of the nuclear fuel, and the development and manufacturing of spent fuel aftertreatment equipment become an important ring for assisting nuclear power development.
Nuclear fuel has extremely strong radiation, so that components in the aftertreatment device that are in direct contact with the nuclear fuel or are located at a long distance can be affected by the strong radiation. In order to ensure the safety of workers, the workers are not close to nuclear fuel and post-processing equipment, so that a remote control mode can be adopted. Similarly, materials other than personnel are also very limited, and materials which are in direct contact with α and β emitting substances are subject to severe radiation damage, so that high requirements are required for equipment materials, and the radiation damage is reduced as much as possible on the premise of meeting functional requirements, that is, the materials are protected against radiation. Besides materials, the working environment of the equipment also demands the type of the equipment, the electromagnetism cannot occur in the working area of the equipment, and the equipment using electricity as an energy source, such as a motor and the like, cannot exist on site, so that only mechanical transmission and a cylinder are used for transmitting power. The bar stock transportation equipment required for post-processing needs to work in a strong radiant heat chamber environment. The extreme working condition is that the use of the material of common rubber is not allowed, and the composition of the nuclear spent fuel is more complex along with the continuous deepening of the fuel consumption of the nuclear fuel, so that the comprehensive performance requirement of the material for the nuclear fuel post-processing equipment is more strict. The design and manufacture of the spent fuel post-treatment equipment are difficult due to the harsh requirements of the equipment environment. The common indoor transfer equipment can not meet the use requirement at all. Therefore, the design and research of the bar transferring equipment suitable for the extreme working condition have very positive significance for the development and the improvement of the nuclear power industry in China.
The appearance of the spent fuel is similar to a rod-shaped material, namely, a shaft-type product, and the transfer equipment of the rod-shaped material is various, and the common equipment types are belt conveyors, roller equipment, AGV trolleys and the like. The belt conveyor is mainly composed of belts which are made of composite materials, so that in the running environment of spent fuel post-processing equipment, common composite materials cannot be used at all, the cost of developing new applicable materials is high, and the conveying mode is not convenient and flexible for bars needing posture adjustment, so that the belt conveyor is not suitable for post-processing equipment. Similarly, the in-situ posture adjustment of the roller transportation equipment for the bar cannot be realized at all, and although the transportation can be carried out in a curve way during the transportation process, the roller transportation equipment is not suitable for being used as post-processing equipment for a linear transportation way in consideration of the occupation of a field. The AGV trolley can not be used as post-processing equipment due to the navigation mode and the driving reason, firstly, the AGV trolley needs a self-contained motor to be used as driving, however, the driving can not be realized in a strong radiation environment, and the magnetic navigation, the laser navigation, the inertial navigation, the two-dimensional code navigation and the like of the main stream are not suitable.
