Abstract

The invention provides a lifting appliance for hoisting a reactor core guide column in the field of lifting tools. The lifting appliance comprises a clamping jaw mounting base, at least two clamping jaws used for clamping the reactor core guide column are hinged to the outer side of the clamping jaw mounting base, and the upper end of the clamping jaw mounting base is fixedly connected with an inner lining, the outer side of the inner lining is sleeved with a clamping sleeve capable of moving up and down in the height direction, a sliding opening is formed in the clamping jaw mounting base, the clamping jaw mounting base is connected with a reset bolt through the sliding opening, the reset bolt can slide along the sliding opening, the sides, opposite to the clamping jaws, of the reset boltabut against the clamping jaws, the reset bolt is sleeved with a reset spring, one end of the reset spring is fixedly connected to the reset bolt, and the other end of the reset spring is connected to the clamping jaw mounting base. The lifting appliance is convenient to use and high in safety and can be applied to hoisting work of the reactor core guide column.

Description

technical field [0001] The invention belongs to the technical field of slings, in particular to a sling device for a guide column. Background technique [0002] The core of a nuclear reactor is also called the reactor active area. It is composed of fuel assemblies placed in a core grid with a certain grid. The fuel assembly is made of fuel elements of a certain shape (plate, rod, tube) through various The components are arranged and assembled according to a certain grid to meet the requirements of physics and thermal hydraulics. The core guide column plays the role of guiding and positioning when hoisting heavy core parts, but the lifting of the core guide column, the traditional method It is necessary for the staff to climb the long ladder in the core area to disassemble and unload the buckle, which increases the risk of staff falling from high altitude, and there is a radiation risk in the core of the nuclear reactor, and the traditional operation poses a greater safety ri...
