Abstract

The invention relates to a special sling device used for lifting nuclear waste. The special sling device is characterized by comprising a connecting plate installed on the beam of a trolley frame, wherein the connecting plate is provided with a telescopic sleeve device; a steel wire rope system and a fixed pulley mechanism connected with the connecting plate are arranged in the telescopic sleeve device; the fixed pulley mechanism is fixed to the bottom end of the telescopic sleeve device; and the fixed pulley mechanism is provided with a special gripping apparatus connecting assembly. The special sling device has the advantages that the whole telescopic sleeve device is driven to move together with the steel wire rope when the steel wire ropes lifts up and falls down, the telescopic sleeve can integrally perform a guiding direction, so that the situation that the steel wire rope of the traditional crane swings can be avoided, accurate positioning can be guaranteed when the special sling device is used for lifting the nuclear waste without shifting and the like, and the operation safety performance of the lifting mechanism of the crane is improved.

Description

technical field

[0001] The invention belongs to the technical field of crane manufacture, in particular to a special hoisting device for hoisting and transporting nuclear waste. Background technique

[0002] Cranes are widely used in aviation, aerospace, nuclear power and other fields, and the hoisting mechanism, as the main part of the crane, has a pivotal application in the crane. The traditional hoisting mechanism sling is a structure that uses wire ropes to connect hooks to directly lift objects. When the lifting height exceeds 3 meters or more, the heavy objects to be lifted will sway with the wire ropes. Due to the particularity of many workplaces and the extreme radiation and hazards of nuclear waste, if traditional hooks are used to directly lift nuclear waste, for the purpose of safety protection, it is necessary to prohibit the lifting of nuclear waste from swinging and other unexpected situations, so the traditional hoisting mechanism spreader cannot meet the spe...
