Long-distance-disassembling-assembling sword-type mechanical arm

Abstract

The invention relates to a long-distance-disassembling-assembling sword-type mechanical arm. The long-distance-disassembling-assembling sword-type mechanical arm is used for a sampling cabinet of a power-reactor fuel-short-after-treatment middle test plant and sampling operation of a plutonium tail-end discharging working box. The inside of a clamp is connected with a nut rod through a rivet, the outside of the clamp is connected with a first sleeve through a countersunk head screw, and the outside of the countersunk head screw is covered with a polytetrafluoroethylene ring; one end of a guiding rod is provided with a screw rod and connected with a nut rod, and the other end of the guiding rod is connected with a core shaft through a pin; the first sleeve and a second sleeve rotate and are pressed through a nut and are connected through a cross recessed pan head screw; a compression spring is arranged at the tail portion of the core shaft and fixed through a spring base, and the spring base is connected with the second sleeve through a thread; a locking screw is arranged on the second sleeve; a trigger is connected with a connecting rod through a rivet, the connecting rod is connected with a rocking rod through a rivet, one end of the rocking rod is fixed at the lower end of a handle, and the other end of the rocking rod goes deep into a square trough at the tail of the core shaft. By means of the long-distance-disassembling-assembling sword-type mechanical arm, the problems that a sword-type mechanical arm trigger falls off, operation is heavy and arduous, the clamp faults, and the spring is lapsed and difficultly replaced are solved.

Description

technical field [0001] The invention relates to a long-distance dismountable sword-type manipulator, which is used for the sampling operation of the Q1, Q2, Q7, Q11 sampling cabinets and the plutonium tail end discharge working box of the power reactor spent fuel reprocessing intermediate test plant. Background technique [0002] The real-time sample analysis of China's Spent Fuel Reprocessing Pilot Plant (hereinafter referred to as the Pilot Plant) is an important basis for process control. The reliability of the remote sampling tool used in the sampling system during the sample analysis process, the sword-type manipulator, directly affects Safe and reliable operation of the process system. During commissioning, the sword manipulator is cumbersome and laborious to operate, and it is difficult to replace the clamp failure or spring failure. These problems increase the difficulty of sampling for operators, reduce the sampling efficiency, and affect the safe operation of the ...
