Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the nuclear fuel related transfer hanger comprises a lifting ring 5, an opening pin 4, a pin shaft 3, a lifting hook 1 and a tongue piece 2. The lifting hook 1 is connected with the lifting ring 5 through a pin shaft 3. The tongue 2 is fixed to the hook 1 by a bolt. The pin shaft 3 respectively connects the lifting hook 1 and the lifting ring 5 together. The cotter pin 4 is inserted on the pin shaft 3 and is matched with the pin shaft for use.
The lifting ring 5 is a circular ring with a section of 22mm, and a pin hole is formed at the joint of the lower part of the circular ring; the cotter 4 is shaped like a Chinese character 'ji'; the pin shaft 3 is a cone; the hook 1 is in the shape of a flattened hook.
The utility model discloses a specifically use as follows:
the lifting hook 1 is used for lifting related components and is connected with a lifting ring 5 through a pin shaft 3. The tongue 2 is used to prevent the associated component from unhooking from the hook 1, and is fixed to the hook 1 by a bolt. The pin shaft 3 is connected to connect the lifting hook 1 and the lifting ring 5 together respectively. The cotter pin 4 prevents the pin shaft 3 from falling off, is inserted on the pin shaft 3 and is matched with the pin shaft for use.
The method of use as shown in fig. 2:
(1) passing a crane hook through a nuclear fuel related assembly transfer spreader lifting eye; (2) lifting the lifting appliance at a constant speed, and lifting the related components by using a lifting hook of the lifting appliance after the lifting appliance is tried to be lifted without problems; (3) uniformly hanging the components to a hanging platform, hanging the related components on the platform, and descending the crane by about 5mm when the related components are hung at the groove of the hanging platform, so that the lifting hook of the lifting appliance is not contacted with the related components; (4) opening the tongue and unhooking (disengaging the associated component from the spreader hook); (5) and lifting the lifting appliance to a safe place, and taking the lifting appliance down from the crane.
The utility model discloses an innovation point: (1) the lifting appliance is adopted to safely and stably lift the related components into/out of the suspension platform; (2) quickly unhooking; (3) compatible with lifting of various nuclear fuel related components; (4) the split structure has higher universality and replaceability.
The lifting appliance needs to meet two design requirements: a) the size requirement is that the lifting hook can enter the interior of the suspension platform; b) the versatility is required to ensure that the spreader can accommodate different size types of associated components. The lifting appliance adopts a split structure mode and is designed into five parts: lifting hook, rings and round pin axle, split pin and tongue piece. Considering the narrow space of the falling groove, the section size of the lifting hook is designed to be 22mm, the hook part at the tail end of the lifting hook is flattened to be 12mm, so that the lifting hook can be easily lifted into the clamping and locking groove by workers at a far position, and meanwhile, the lifting ring needs to be lengthened to ensure that the lifting hook can be lifted into the clamping and locking groove. The common crane is only provided with one lifting hook and does not have universality, the special lifting hook adopts a structure that the lifting ring is added with the lifting hook, the special lifting hook can be special and can be universal with other cranes or lifting appliances, the lifting ring and the lifting hook of the structure are positioned by adopting the cylindrical pin, the lifting ring and the lifting hook are convenient to disassemble, and the requirement on the universality is met.
