Abstract
The utility model belongs to in-pile members of a reaction pile and particularly relates to a screwing-in type hoisting structure with replaceable lifting devices. The structure is characterized in that petal type screwing-in hoisting holes with single-layer bearing teeth are arranged on the circle of a flange of a piece to be hoisted, the lower portion of each hoisting hole is a round hole, the upper portion of each hoisting hole is a petal-shaped hole, and a lifting rod location hole is arranged at the center of the hoisting hole. A lifting rod limit hole is arranged on the flange face beside each hoisting hole. One, two or three hoisting structures can be evenly arranged on the circle of the flange of the piece to he hoisted according to requirements. The structure can achieve replacement of lifting rods, and is small in occupied space, simple in structure, low in manufacture cost and reliable in use.
Description
Technical field
The utility model belongs to reactor core internals, is specifically related to the interchangeable screw-in hoisting structure of a kind of suspender.
Background technology
At present, both at home and abroad in the nuclear power plant reactor, the lifting of in-pile component adopts the lifting of multiple field as shown in Figure 1 and Figure 2 to screw in the part structure, and this lifting screws in part inside and has three layers of load-bearing tooth, by with the engagement realization of the special-purpose lifting boom lifting to in-pile component.A hanging piece of this three layers of load-bearing tooth is complex structure not only, and productive costs is high, also necessarily requires one to one repair use of lifting boom, has caused lifting appliance not have interchangeability; In addition, three layers of force structure easily produce unbalance stress, affect safe lifting.
Summary of the invention
The purpose of this utility model is to provide a kind of screw-in hoisting structure that suspender use interchangeability is good, simple in structure, use is reliable, cheap that has, to overcome the prior art above shortcomings.
For achieving the above object, technical solution adopted in the utility model is:
The interchangeable screw-in hoisting structure of a kind of suspender, its version is: have the petal type screw-in lifting eye that the load-bearing tooth is individual layer at the circumference of flange that is played hanging piece, the bottom of lifting eye is circular port, and top is petal hole, has a suspension rod knock hole in the lifting eye center; Flange face on the lifting eye next door has a suspension rod spacing hole.
One, two or three these hoisting structures have been evenly arranged at the circumference of flange that is played hanging piece.
The obtained beneficial effect of the utility model is:
The in-pile component that the utility model is limited for the nuclear reactor spatial location, inconvenience arranges hanger, cancel the lifting in the background technology and screwed in part, on by the flange of a hanging piece, directly open the petal type screw-in lifting eye structure that the load-bearing tooth is individual layer, can realize the exchange of suspension rod, this hoisting structure occupies little space, simple in structure, low cost of manufacture, use are reliable.

Fig. 3 is the interchangeable screw-in hoisting structure of suspender described in the utility model scheme drawing;
Fig. 4 is the interchangeable screw-in hoisting structure of suspender described in the utility model B-B view;
Among the figure: 1, played hanging piece; 2, suspension rod knock hole; 3, suspension rod spacing hole, 4, lifting eye.
The specific embodiment
In reactor, it is the cartridge type hanging structure that quilt plays a hanging piece 1, the interchangeable screw-in hoisting structure of suspender described in the utility model is positioned on the flange that is played hanging piece 1 cylindrical shell, as shown in Figure 3, Figure 4, its version is: have the petal type screw-in lifting eye 4 that the load-bearing tooth is individual layer at the circumference of flange that is played hanging piece 1, the bottom of lifting eye 4 is circular port, and top is petal hole, have a suspension rod knock hole 2 in lifting eye 4 centers, to realize the axial location of suspension rod; Flange face on lifting eye 4 next doors has a suspension rod spacing hole 3, rotates in a circumferential direction to prevent suspension rod.
Play the structure of hanging piece 1 according to concrete quilt, can be evenly arranged one, two or three these hoisting structures at the circumference of flange that is played hanging piece 1, take accordingly single pole, two bar or three bar handlings, the lifting contact level of suspension rod is parallel with flange face, and is vertical with boom axis.According to by the weight of 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 dowel pin of suspension rod lower end inserts in the suspension rod knock hole 2, petal type load-bearing tooth enters the circular port of bottom by the petal hole on lifting eye 4 tops, and the rotation suspension rod makes the load-bearing tooth of suspension rod overlap with the bearing surface of lifting eye 4 load-bearing teeth, the locating dowel pin of suspension rod is inserted in the suspension rod spacing hole 3, to prevent the suspension rod rotation.
Claims (2)
1. interchangeable screw-in hoisting structure of suspender, it is characterized in that: its version is: have the petal type screw-in lifting eye (4) that the load-bearing tooth is individual layer at the circumference of flange that is played hanging piece (1), the bottom of lifting eye (4) is circular port, top is petal hole, has a suspension rod knock hole (2) in lifting eye (4) center; Flange face on lifting eye (4) next door has a suspension rod spacing hole (3).
2. the interchangeable screw-in hoisting structure of suspender according to claim 1 is characterized in that: be evenly arranged one, two or three these hoisting structures at the circumference of flange that is played hanging piece (1).
