Cam mechanism and balance turning out-in device in hot cell

Abstract

The invention provides a cam mechanism and a balance turning out-in device in a hot cell. A cam lock comprises a lock base, a sliding block, a cam, a torsional spring, a compression spring and a sliding shaft; through the design of the torsional spring, the compression spring and a triangle sliding groove of the sliding block, in the process that the cam which is driven by the sliding block or the sliding shaft changes from unfolding to folding and then from folding to unfolding, the sliding block only needs to slide in one direction, so that the cam mechanism is convenient to operate and is suitable for a manipulator which can only conduct simple actions to operate. The cam mechanism is assembled on the balance turning out-in device on a hanger, a powered mechanical arm grabs the hanger and drives the balance turning out-in device to descend and ascend, and the turning out-in of the balance can be completed. The balance turning out-in device is easy to operate, and by using the existing powered mechanical arm, the turning out-in of the balance can be completed; the balance turning out-in device is easy to operate and high in efficiency, and when the balance fails and needs to be maintained or replaced, it is not required for a worker to enter the hot cell, so that the balance turning out-in device is safer.

Description

technical field [0001] The invention relates to the technical field of a tongue-turning mechanism and a balance moving device applied in a thermal chamber, in particular to a tongue-turning mechanism and a balance rotating in and out of a thermal chamber including the tongue-turning mechanism. Background technique [0002] Hot cells, shielded chambers for highly radioactive experiments and operations. Due to the radiation hazard of radioactive materials, during operation, personnel stand outside the hot chamber, observe the internal equipment through the lead glass window on the hot chamber, and operate the materials and equipment inside the hot chamber through the power mechanical arm. [0003] When operating the electronic balance in the hot chamber, due to the existence of radioactivity, it is impossible for personnel to directly touch the balance. They must stand outside the shielded heat chamber, through the lead glass window, and operate the balance through a remote op...
