The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
This lifting comprises suspension hook attaching parts 2, last coupling assembling 3, girder 4, following coupling assembling 5 and steel rope attaching parts 6 with equalizing bar.
Suspension hook attaching parts 2, its upper end connecting shackle assembly 1, the lower end connects goes up coupling assembling 3, is the significant components of this equalizing bar.Because the difference of suspension hook version exists single hole to connect and is connected two kinds of forms with diplopore, according to these two kinds of forms, the design of suspension hook attaching parts 2 is different.
For the single hole suspension hook, suspension hook attaching parts 2 comprises 21,23 and two triangle connecting plates 22 of two bearing pins.Wherein triangle connecting plate 22 tops are connected with suspension hook 11 with bearing pin 21, and the bottom connects the arm-tie 3 of going up coupling assembling with bearing pin 23.
For the diplopore suspension hook, suspension hook attaching parts 2 comprises 24,27, four triangle connecting panels 25 of two bearing pins and two blocks of balance plates 26.The top of per two triangle connecting panels 25 is connected with suspension hook 12 with bearing pin 24, the bottom fluting and balance plate 26 weld togethers of triangle connecting panel 25.Connect balance plate 26 and last coupling assembling 3 with bearing pin 27.
The suspension hook attaching parts of said structure also is suitable for the connection of the suspension hook of other structure simultaneously.
Last coupling assembling 3 is identical with the structure of following coupling assembling 5.Above coupling assembling 3 is the structure of these two coupling assemblings of example explanation.Last coupling assembling 3 includes many group arm-tie groups, and these arm-tie groups are divided into narrow arm-tie group and wide arm-tie group again.Each arm-tie group is formed arm-tie 31 two ends semicircular in shape or half elliptics by two arm-ties that are parallel to each other 31.Wide arm-tie group alternately is connected with bearing pin 32 with narrow arm-tie group during connection, and two arm-ties of narrow arm-tie group are between two arm-ties of wide arm-tie group.The upper end 3 connecting shackle attaching partss 2 of last coupling assembling 3, the lower end connects girder 4; The upper end of following coupling assembling 5 connects girder 4, and the lower end connects steel rope attaching parts 6.
Equalizing bar girder 4 comprises mobile jib 41, organizes board-like hanger 42, end connecting panel 43 and tie bolt 44 more.Girder 4 is pressure parts of equalizing bar, is that rectangle is better for the ease of its cross section of welding otic placode.Corresponding with the arm-tie group, every group of board-like hanger 42 also is made up of two hangers.Hanger 42 integral manufacturings in the present embodiment, fluting passes mobile jib 41 with board-like hanger 42 earlier on mobile jib 41, welds then, and this structure welding quality is better.Can assemble by one group of board-like hanger 42 of each any selection of every as required end during lifting at the board-like hanger 42 of the many groups of the two ends of an equalizing bar girder base portion 41 welding.For the range of use of expanding equilibrium beam, two parts that present embodiment is designed to girder to removably connect, promptly the one or both ends of every mobile jib 41 are provided with connecting panel 43, are connected with the mobile jib of another girder with bolt 44.Each mobile jib 41 can use separately like this, and the use that also can link together has enlarged the range of use of equalizing bar greatly, has reduced manufacturing cost.
Steel rope attaching parts 6 is made up of triangle connecting plate 61, bearing pin 62, dividing plate 63 and steel pipe 64.Wherein, triangle connecting plate 61 has two.The top of triangle connecting plate 61 connects coupling assembling 5 down through bearing pin 62, and the upper end of following coupling assembling 5 is connected with board-like hanger 42 through bearing pin 51.If in the time of need not using down coupling assembling 5, the board-like hanger 42 of the top direct connection of triangle connecting plate 61; The bottom fluting welding diaphragm 63 of triangle connecting panel 61, dividing plate 63 quantity are provided with as required, and present embodiment median septum 63 has four.Open circular hole through weld steel pipe 64 in the bottom of dividing plate 63, dividing plate 63 constitutes a tubular shaft type hanger of cutting apart with steel pipe 64, is used to connect steel rope.Above-mentioned dividing plate and steel-tube construction also can change dividing plate, bearing pin and pulley structure into.Length of steel wire rope is fixed, and the equalizing bar lower length realizes through the length of adjusting down coupling assembling 5.
