Abstract
The invention belongs to a component in a pile of a reactor, and particularly relates to a screw-in hanging structure with interchangeable hanging tools. The screw-in hanging structure has the following structural form that a petal type screw-in hanging hole with single-layer load bearing teeth is formed in the circumference of a flange of a hung element, the lower part of the hanging hole is a round hole, the upper part of the hanging hole is a petal-shaped hole, a hanging rod positioning hole is formed in the center position of the hanging hole, and a hanging rod position limiting hole is formed in the flange surface beside the hanging hole. One, two or three hanging structure(s) can be uniformly arranged on the circumference of the flange of the hung element according to requirements. The screw-in hanging structure can realize the interchange of hanging rods, and has the advantages that the occupied space is small, the structure is simple, the manufacturing cost is low, and the use is reliable.
Description
Technical field
The invention belongs to reactor core internals, be specifically related to the interchangeable screw-in hoisting structure of a kind of suspender.
Background technique
At present, in nuclear power plant reactor, the lifting of in-pile component adopts the lifting of multiple layer as shown in Figure 1 and Figure 2 to screw in the part structure both at home and abroad, and this lifting screws in part inside and has three layers of load-bearing tooth, by the engagement with special-purpose lifting boom, realizes the lifting to in-pile component.A hanging piece of this three layers of load-bearing tooth is complex structure not only, and cost of production is high, also necessarily requires lifting boom repair use one to one, has caused lifting appliance not have interchangeability; In addition, three layers of force structure easily produce unbalance stress, affect lifting safety.
Summary of the invention
The object of the present invention is to provide a kind of have suspender use interchangeability good, simple in structure, use reliable, cheap screw-in hoisting structure, to overcome the prior art above shortcomings.
For achieving the above object, the technical solution used in the present invention is:
The interchangeable screw-in hoisting structure of a kind of suspender, its structural type is: have the petal type that the load-bearing tooth is individual layer and screw in lifting eye on the circumference of flange by a hanging piece, the bottom of lifting eye is circular port, and top is petal hole, has a suspension rod positioning hole in the lifting eye central position; Have a suspension rod spacing hole on the flanged surface on lifting eye side.
One, two or three these hoisting structures have been evenly arranged on the circumference of flange by a hanging piece.
The obtained beneficial effect of the present invention is:
The present invention is directed to the in-pile component that the nuclear reactor spatial location is limited, inconvenience arranges hanger, cancel the lifting in the background technique and screwed in part, directly open the petal type that the load-bearing tooth is individual layer and screw in the lifting eye structure on the flange by a hanging piece, can realize the exchange of suspension rod, this hoisting structure occupies little space, simple in structure, low cost of manufacture, use are reliable.
The accompanying drawing explanation
The lifting that Fig. 1 is multiple layer screws in the part structural representation;
The lifting that Fig. 2 is multiple layer screws in part structure A-A view;
Fig. 3 is the interchangeable screw-in hoisting structure of suspender of the present invention schematic diagram;
Fig. 4 is the interchangeable screw-in hoisting structure of suspender of the present invention B-B view;
In figure: 1, played hanging piece; 2, suspension rod positioning hole; 3, suspension rod spacing hole, 4, lifting eye.
Embodiment
In reactor, by playing hanging piece 1, it is the cartridge type suspender structure, the interchangeable screw-in hoisting structure of suspender of the present invention is positioned on the flange that is played hanging piece 1 cylindrical shell, as shown in Figure 3, Figure 4, its structural type is: have the petal type that the load-bearing tooth is individual layer and screw in lifting eye 4 on the circumference of flange by a hanging piece 1, the bottom of lifting eye 4 is circular port, and top is petal hole, have a suspension rod positioning hole 2 in lifting eye 4 central positions, to realize the axially locating of suspension rod; Have a suspension rod spacing hole 3 on the flanged surface on lifting eye 4 sides, rotate in a circumferential direction to prevent suspension rod.
According to the concrete structure that is played hanging piece 1, can on the circumference of flange by a hanging piece 1, be evenly arranged one, two or three these hoisting structures, take accordingly single pole, two bar or three bar handlings, the lifting contact plane of suspension rod is parallel with flanged surface, vertical with boom axis.According to the weight by handling part 1, determine the size of suspension rod and the package size in each hole.The suspension rod lower end has petal type load-bearing tooth, petal hole coupling with lifting eye 4, during use, the locating stud of suspension rod lower end inserts in suspension rod positioning hole 2, petal type load-bearing tooth enters the circular port of bottom by the petal hole on lifting eye 4 tops, the rotation suspension rod, make the load-bearing tooth of suspension rod overlap with the stress surface of lifting eye 4 load-bearing teeth, the position limit pin of suspension rod is inserted in suspension rod spacing hole 3, to prevent the suspension rod rotation.
Claims (2)
1. the interchangeable screw-in hoisting structure of suspender, it is characterized in that: its structural type is: have the petal type that the load-bearing tooth is individual layer and screw in lifting eye (4) on the circumference of flange by a hanging piece (1), the bottom of lifting eye (4) is circular port, top is petal hole, in lifting eye (4) central position, has a suspension rod positioning hole (2); Have a suspension rod spacing hole (3) on the flanged surface on lifting eye (4) side.
2. the interchangeable screw-in hoisting structure of suspender according to claim 1, is characterized in that: on the circumference of flange by a hanging piece (1), be evenly arranged one, two or three these hoisting structures.
