Disassembling and assembling tool for clamping jaw of loading and unloading machine

Abstract

The invention discloses an disassembling and assembling tool for a clamping jaw of a loading and unloading machine. The disassembling and assembling tool comprises a lifting appliance and a base, wherein the lifting appliance is detachably connected to the upper portion of the clamping jaw of the loading and unloading machine and used for lifting the clamping jaw of the loading and unloading machine, and the base is detachably installed on the lower portion of the clamping jaw of the loading and unloading machine and used for bearing the clamping jaw of the loading and unloading machine. The base comprises a base body and a lifting mechanism, wherein the base body is detachably connected with the clamping jaw of the loading and unloading machine and used for bearing the clamping jaw of the loading and unloading machine, and the lifting mechanism is connected with the base body to drive the base body to ascend and descend so as to adjust the position of the clamping jaw of the loading and unloading machine. The disassembling and assembling tool for the clamping jaw of the loading and unloading machine can quickly and safely realize the disassembling and assembling work of the clamping jaw of the loading and unloading machine, reduce the working time of personnel and reduce the exposure dose of the personnel.

Description

technical field [0001] The invention relates to the field of nuclear power, and more specifically relates to a disassembly tool for loading and unloading machine jaws. Background technique [0002] The disassembly and assembly of the jaws of the loading and unloading machine is currently an underwater high-risk operation carried out by various power stations of the CGNPC to ensure the smooth progress of the refueling overhaul, that is, it is installed before the overhaul and unloading, and is removed after loading. The operation site for this work is the maintenance platform between the core pool and the component pool. The platform has a drop of about 4 meters and no physical guardrails. During the whole operation, the loading and unloading operator needs to cooperate with the lifting and lowering of the jaws on the loading and unloading machine. [0003] At present, the following problems exist in the disassembly and assembly of the jaws of the loading and unloading machi...

AI Technical Summary

Problems solved by technology

[0004] 1) Work is carried out on the maintenance platform between the stack pool and the component pool. There is a drop of 4 meters between the platform and the bottom of the component pool. Two people are required to operate. The area is relatively small, and there is no guardrail protection in this area, so there is a risk of people falling :

[0005] 2) The grippers cannot be hoisted alone and need to be hoisted in a container. In addition to disassembling and assembling the grippers, the operators also need to perform container switching operations. The working time of the personnel in the pool is quite long, and the radiation exposure to the personnel is relatively long. higher doses;

[0006] 3) During the operation, the operator of the loading and unloading machine usually needs to operate the main lift to cooperate with the installation of the grippers, and there is a risk of crushing injuries caused by poor communication between the operators at the bottom of the pool and the operators
