An automatic grabbing and lifting device in a reactor

Abstract

The invention discloses a reactor internal automatic grabbing lifting device. The reactor internal automatic grabbing lifting device comprises an upper layer fixing plate, a middle layer fixing plateand a lower layer fixing plate which are sequentially connected, the upper layer fixing plate is provided with a lifting lug, and the reactor internal automatic grabbing lifting device further comprises a center shaft penetrating through the upper layer fixing plate, and a first driving mechanism for driving the center shaft to rotate; and a transmission mechanism is arranged between the upper layer fixing plate and the middle layer fixing plate, the center shaft is connected with the transmission mechanism, a driving plate is arranged between the middle fixing plate and the lower layer fixingplate, the first driving mechanism drives the driving plate to rotate, the driving plate is provided with two fixing shafts, and catch pawls are mounted on the fixing shafts. The reactor internal automatic grabbing lifting device is used for solving the problems that the safety potential hazards exist in the prior art by adopting manual material and device replacing for reactor in-out operations,and staff frequently walking around at the top of the reactor and implementing operation tasks are prone to bring sundries into the reactor, and thus the safety potential hazards exist in the reactor, and the purposes that reactor external remote control can be achieved, the situation that operators are exposed to the area with the high dose is prevented, and the potential risk on the reactor isavoided are achieved.

Description

technical field [0001] The invention relates to the field of irradiation of reactor materials, in particular to an automatic grasping and lifting device in a reactor. Background technique [0002] The internal structure of the reactor is complex, but it is often accompanied by components such as refueling, transfer of fuel rods, and irradiation devices, which require specific lifting and transfer devices to perform the above operations. Because the core is submerged in water and there are potential hazards such as radiation sources in the reactor, the transfer and replacement of all components in the reactor are performed outside the reactor. Due to the differences in the irradiation requirements of each furnace section, the required neutron fluence rate is also different. In order to meet the operation requirements, it is necessary to continuously adjust the position of the fuel rods and arrange them reasonably to meet the requirements. In the process of adjusting the fuel...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an automatic grasping and lifting device in the reactor to solve the problem of manual refueling and part of the device entering and exiting the reactor in the prior art, which requires operators to go to the top of the reactor to implement, there are potential safety hazards, and it is easy to be exposed to radiation. Good health; in addition, the staff frequently walk around the top of the reactor and carry out operational tasks, and it is easy to bring debris into the reactor, which makes the reactor a safety hazard. It can realize remote control outside the reactor and prevent operators from breaking the news in areas with high doses. , also for the purpose of avoiding potential hazards to the reactor
