Deep well curing barrel hoisting system and method

Abstract

A deep well curing barrel hoisting system comprises a running gear, a horizontal transfer device, a logging center device, a hanging scaffold shifting mechanism, a hanging scaffold, a barrel surface cleaning device and a spray and dust reduction mechanism. A curing barrel hoisting method based on the deep well curing barrel hoisting system comprises the following step 1 of setting a coordinate system; the step 2 of locating a wellhead center; the step 3 of regulating a hoisting position; the step 4 of removing wastes and floating dust on a curing barrel; the step 5 of further centering the curing barrel through a hook claw; the step 6 of hoisting the curing barrel; and the step 7 of transferring the curing barrel onto a barrel carrier vehicle. The deep well curing barrel hoisting system and method has the advantages that the deep well curing barrel hoisting system can be controlled remotely for avoiding nuclear radiation effectively; an electromagnetic chuck can be in butt joint with the curing barrel accurately; and the curing barrel is hoisted steadily and prevented from colliding with walls.

Description

technical field [0001] The invention relates to the technical field of curing barrel recycling, in particular to a deep well curing barrel lifting system and a lifting method thereof. Background technique [0002] The curing barrels used to hold the solidified nuclear waste cement are usually stacked layer by layer and temporarily stored in the mine. The diameter of the mine is slightly larger than the diameter of the curing barrels. The depth of the mine can reach 14m, and at least 12 layers of curing barrels can be stacked. [0003] At present, the operation of recovering curing barrels is usually carried out by crane. The difficulties are as follows: 1. The crane needs the operator to sit in the cockpit of the crane to control the driving. The operator will be more or less exposed to nuclear waste radiation, and the health risk of operation is relatively high. 2. The electromagnetic spreader is flexibly connected to the remote control car of the crane, so the swing range...
