Abstract
The invention discloses a kind of constructional devices for increasing major diameter steel wire rope loop bending radius, including outer ring round tube, inner ring round tube and cover board, the inner ring round tube to be fixed in outer ring round tube, and the cover board is fixed on outside outer ring round tube.The present invention increases the constructional device of major diameter steel wire rope loop bending radius, and increased steel wire rope loop bending radius is original twice of shackle pin shaft, meets steel wire rope loop safe handling and requires；Production is simple, practical, can be used for all large-scale steel wire rope loops and connect aspect with flat shackle.
Description
Technical field
The present invention relates to a kind of constructional devices for increasing major diameter steel wire rope loop bending radius.
Background technique
Marine worker module hoisting is the key project of our company, and module needs to be connected with steel wire rope loop and flat shackle after building
The lifting that composition rigging carries out marine worker module is connect, but when connecting using the identical flat shackle of rated load with steel wire rope loop,
The pin diameter of its flat shackle and steel wire rope loop diameter are very close, will lead to steel wire rope loop in this way around flat shackle
Pin shaft when bending efficiency factor reduce, be not able to satisfy steel wire rope loop safe handling and require, steel wire rope loop inner core can produce when use
Raw fracture, risk is very big, but if selecting, although the flat shackle of major diameter pin shaft is able to solve this problem but meeting is very big
Increase hoisting cost, economic effect is very low, so steel wire rope loop bending radius constructional device can be increased by being badly in need of one kind, and can
It is effectively connect with flat shackle.
Summary of the invention
The object of the present invention is to provide one kind can increase steel wire rope loop bending radius, and can be had with flat shackle
Imitate the constructional device of the increase major diameter steel wire rope loop bending radius of connection.
Present invention technical solution used for the above purpose is: a kind of increase major diameter steel wire rope loop bending radius
Constructional device, including outer ring round tube, inner ring round tube and cover board, the inner ring round tube be fixed in outer ring round tube, the cover board
It is fixed on outside outer ring round tube.
Cement filler is equipped between the outer ring round tube and inner ring round tube.
A kind of constructional device for increasing major diameter steel wire rope loop bending radius of the present invention, increased steel wire rope loop bending radius
It is original twice of shackle pin shaft, meets steel wire rope loop safe handling and require；Production is simple, practical, can be used for all large sizes
Steel wire rope loop connect aspect with flat shackle.
Detailed description of the invention
Fig. 1 is a kind of main view for the constructional device for increasing major diameter steel wire rope loop bending radius of the present invention.
Fig. 2 is a kind of side view for the constructional device for increasing major diameter steel wire rope loop bending radius of the present invention.
In figure: 1, outer ring round tube；2, inner ring round tube；3, cover board；4, cement filler.
Specific embodiment
As depicted in figs. 1 and 2, increase the constructional device of major diameter steel wire rope loop bending radius, including outer ring round tube 1, interior
Ring round tube 2 and cover board 3, inner ring round tube 2 are fixed in outer ring round tube 1, and cover board 3 is fixed on outside outer ring round tube, outer ring round tube and interior
Cement filler 4 is equipped between ring round tube, the internal diameter of inner ring round tube 2 is that flat shackle pin diameter adds 6 millimeters, and round tube is thick
Degree is not less than 20 millimeters, and round tube height is that steel wire rope loop diameter adds 10 millimeters, and 1 outer diameter of outer ring round tube is steel wire rope loop diameter
2 times, thickness is not less than 20 millimeters, and round tube height is that steel wire rope loop diameter adds 10 millimeters, and inner ring round tube 2 is welded to outer ring round tube
In 1, it is 150 millimeters bigger than 1 diameter of outer ring round tube then to weld its diameter dimension of side cover plate 4(, and steel wire rope loop is prevented to be disengaged from the groove), then
Cement filler 3 is poured into, solidification is welding another side cover plate 4 after a certain period of time, and overall structure production finishes, which makes
Steel wire rope loop is inserted in constructional device first by the used time, and then flat shackle pin shaft is inserted into inner ring round tube 2 and is fixed, has been connected
Finish.
