Mechanical lifting device for radioactive drying salt barrel

Abstract

The invention discloses a mechanical lifting device for a radioactive drying salt barrel. The device comprises a lifting ring assembly, a lifting rod, a mechanical locking lock cylinder assembly, an upper faceplate, a lifting hook connecting rod, a pull rod and a lower faceplate, and the inner ring surface of the upper faceplate is fixedly connected with the outer side surface of the mechanical locking lock cylinder assembly; and the lower end of the lifting rod penetrates through the mechanical locking lock cylinder assembly to be rotatably connected with the inner ring face of the lower faceplate arranged below the upper faceplate, the upper end of the lifting hook connecting rod is rotatably connected with the upper faceplate through a rotating shaft, the first end of the pull rod is rotatably connected with the lower faceplate, and the second end of the pull rod is rotatably connected with the middle end of the lifting hook connecting rod. The lifting rod can slide up and down relative to the upper faceplate. The included angle between the lifting hook connecting rod and the upper faceplate is changed by arranging the lifting rod to slide up and down relative to the upper faceplate, so that the drying salt barrel is lifted by clamping the lower end of the lifting hook connecting rod in the drying salt barrel, and the mechanical locking lock cylinder assembly is arranged to be of a mechanical structure and can be fixed without other power.

Description

technical field [0001] The invention relates to the technical field of radioactive waste treatment, in particular to a mechanical hoisting device for radioactive dry salt barrels. Background technique [0002] The nuclear waste drum containing the dry salt cake formed by microwave drying of the radioactive concentrate is heavy and has a high radioactive level. After the process is completed, it needs to be transported to a specific location in the plant for temporary storage by using a lifting device. In this process, due to the high level of radioactivity in the drying barrel, manual direct handling cannot be used, and due to the requirements of the front-end process, the steel barrel is of a specific type, and the existing spreader cannot effectively and safely realize this function. A special spreader to complete the dry drum transfer work. However, the existing suspensions include electromagnetic suspenders, electric suspenders, etc., which may cause radioactive waste t...

In this process, due to the high level of radioactivity in the drying barrel, manual direct handling cannot be used, and due to the requirements of the front-end process, the steel barrel is of a specific type, and the existing spreader cannot effectively and safely realize this function. A special spreader to complete the dry barrel transfer work

However, the existing hoists include electromagnetic hoists, electric hoists, etc., and there is a risk of radioactive waste falling after the power is cut off during use.
