Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 As shown, the nuclear fuel-related transfer spreader includes a lifting ring 5 , a cotter pin 4 , a pin shaft 3 , a hook 1 and a tongue 2 . The suspension hook 1 is connected to the suspension ring 5 through a pin shaft 3 . The tongue 2 is fixed on the hook 1 by bolts. Pin shaft 3 connects suspension hook 1 and suspension ring 5 together respectively. Cotter pin 4 is inserted on the bearing pin 3, uses with it.

[0020] Suspension ring 5 is the annulus that section is 22mm, and annulus bottom joint has pin hole; Cotter pin 4 is similar several fonts; Bearing pin 3 is a cone; Suspension hook 1 is the hook shape of squashing.

[0021] Concrete use of the present invention is as follows:

[0022] The hook 1 is used for hoisting related components, and it is connected with the lifting ring 5 through the pin sh...

Abstract

The invention discloses a transfer lifting appliance for nuclear fuel related assemblies. The transfer lifting appliance comprises a lifting ring, a cotter pin, a pin shaft, a lifting hook and a tongue piece. The lifting hook is connected with the lifting ring through the pin shaft. The tongue piece is fixed to the lifting hook through a bolt. The lifting hook and the lifting ring are connected together through the pin shaft. The cotter pin is inserted into the pin shaft and used in cooperation with the pin shaft. The transfer lifting appliance has the beneficial effects that (1) the related assemblies are safely and stably lifted into / out of a suspension platform, and quick unhooking is achieved; (2) no damage (including scratches) is generated in the process that the related assemblies are lifted into / out of the suspension platform; (3) the multiple related assemblies can be lifted through the same lifting appliance; (4) the transfer efficiency of the related assemblies is improved by five times; (5) no lifting rope needs to be manually used, and safety is guaranteed; and (6) the split structure is adopted, and universality and replaceability are higher.

Description

technical field [0001] The invention belongs to a sling, in particular to a transfer sling for nuclear fuel-related components. Background technique [0002] The present invention is mainly designed with respect to the spreader used for the lifting of nuclear fuel-related components. Components are the core components in a nuclear power plant reactor, including fuel components and related components, among which the fuel components provide nuclear energy for the nuclear reactor, and the related components adjust the reactor speed. After the relevant components are produced, they need to be hung vertically on The components in the production hall are suspended on the platform, and before the qualified related components are loaded into the transport container, the corresponding spreader or lifting rope is required. [0003] In the process of hoisting related components abroad, countries including France and the United Kingdom have designed corresponding spreaders for differe...
