Below, with reference to accompanying drawing, embodiments of the present invention are described.
Fig. 1 shows and uses the lifting fixture of embodiment of the present invention to sling as the state of the winch of weight, and its figure (a) is front view, and its figure (b) is left side view.In addition, Fig. 2 is the view of the lifting fixture amplifying display Fig. 1, and its figure (a) is front view, and its figure (b) is left side view.
As shown in Figure 2, lifting fixture 1 is tunnel type (roughly U-shaped), and it is made up of bottom (first component) 1a, upper end 1b (second component) and link (the 3rd parts) 1c.Link 1c connects the parts of bottom 1a and upper end 1b, makes this three in one, has the intensity of the weight that is enough to sling.
The bottom 1a of lifting fixture 1 arranges through hole (the first connecting portion) 1d that lifting fixture 1 is connected with the main body peripheral part 2a of winch 2.And, first eyebolt 3 is inserted in this through hole 1d, make the bottom 1a of its through lifting fixture 1, and be arranged in mounting hole that (being screwed into) be formed on the main body peripheral part 2a of winch 2 (not shown: sling point 2b), thus lifting fixture 1 can be fixed on winch 2.
On the other hand, tapped bore (the second connecting portion) 1e for installing the second eyebolt 4 is set at the upper end 1b of lifting fixture 1.Second eyebolt (parts of slinging) 4 is screwed in this tapped bore 1e, and is arranged on the upper end 1b of lifting fixture 1.Further, by the hook 5a of chain block 5 being inserted the ring part of this second eyebolt 4, and elevator chain movable pulley 5, thus can to sling winch 2 to lifting direction 8.
Winch 2 is provided with the disk 9 with reel 11 unitary rotation of winding cords.Disk 9 is by clamping this disk 9 to carry out the dish-style brake disc braked.In the present embodiment, the center of turn of disk 9 is exactly the center of gravity 6 of this winch 2.
In the drawings, Reference numeral 12 is the perpendicular line (dummy line) by the center of gravity 6 of winch 2 under the attitude when arranging, in the present embodiment, to be set in the center of the tapped bore 1e that the upper end 1b of lifting fixture 1 is formed by the mode of above-mentioned perpendicular line 12.When arranging, due to disk 9 facing to vertical direction, therefore, if make the face of disk 9 parallel with above-mentioned perpendicular line 12, then sling winch 2 time winch 2 can not tilt.Therefore, even if due to winch 2 of being sling by the second eyebolt 4 be arranged on tapped bore 1e, still vertically direction, the face of disk 9, so winch 2 can not tilt.
On the other hand, through hole 1d in the horizontal direction with standoff distance h in vertical direction between the lower end 1a ' of perpendicular line 12 standoff distance x, above-mentioned bottom 1a and the lower end 1b ' of above-mentioned upper end 1b.Horizontal throw x is the distance of mounting hole at a distance of perpendicular line 12 of the main body peripheral part 2a of the position being arranged on the winch 2 that is suitable for slinging.In addition, vertical distance h is the distance that the lower end 1b ' of the upper end 1b ensureing lifting fixture 1 can exceed the most peripheral of disk 9, is the distance from the upper surface (the lower end 1a ' of the bottom 1a of lifting fixture 1) of main body peripheral part 2a to the lower end 1b ' of the upper end 1b of lifting fixture 1.Consider that the size of this horizontal throw x, the first eyebolt 3 and disk 9 are apart from the overhang of bottom 1a, not produce with them the mode disturbed, set the size of the space 1f formed by bottom 1a, upper end 1b and connecting portion 1c.
When this lifting fixture 1 of use slings winch 2, first, make the first eyebolt 3 by through hole 1d, to be connected by the lifting fixture 1 shown in Fig. 2 and to be fixed on the main body peripheral part 2a of winch 2.Now, the center being formed in the tapped bore 1e on the upper end 1b of lifting fixture 1 is adjusted to by this perpendicular line 12, afterwards, tightens and fixes the first eyebolt 3.Lifting fixture 1 is arranged on winch 2 in this way.
In addition, when object of slinging is not winch 2 too, when being arranged on this object by lifting fixture 1, the center being formed in the tapped bore 1e on the upper end 1b of lifting fixture 1 is adjusted on the line that is positioned at by this object center of gravity.In addition, as mentioned above, because horizontal throw x and vertical distance h is different because of the difference of object of slinging, so, can suitably make according to object of slinging or prepare lifting fixture 1.
If form lifting fixture 1 in this way and be arranged on winch 2, then, when slinging, the axis being arranged on the second eyebolt 4 on lifting fixture 1 is consistent with perpendicular line 12.Therefore, when utilize chain block 5 sling the second eyebolt 4 time, to make to keep the state consistent with the axis of the second eyebolt 4 by the perpendicular line 12 of the center of gravity 6 of winch 2, winch 2 can be sling.In this state, because the main body end face of disk 9 and winch 2 can not tilt from vertical direction, namely can not tilt relative to perpendicular line 12, so, even if when by narrower and small peristome 7a on ground, Machine Room 7, also hoisting operation can be carried out when winch 2 different openings portion 7a produces interference.
