The utility model to be described further below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that.
See also Fig. 1 to Fig. 8, wherein, Fig. 1 is the main TV structure schematic diagram of the first positioning plate of positioning plate group in a kind of shackle positioning plate device embodiment that the utility model proposes.Fig. 2 is that the A of Fig. 1 is to structural representation.Fig. 3 is the main TV structure schematic diagram of the second positioning plate of positioning plate group in a kind of shackle positioning plate device embodiment that the utility model proposes.Fig. 4 is that the B of Fig. 3 is to structural representation.Fig. 5 is the structural representation of the second positioning plate be provided with in the first positioning plate handle or Fig. 3 of the first positioning plate in Fig. 1 when being provided with the second positioning plate handle.Fig. 6 is that a kind of shackle positioning plate device embodiment that the utility model proposes is arranged on the structural representation unloading and buckle.Fig. 7 is A-A cutting structural representation when hanging yard eye plate and horizontal surface out of plumb in Fig. 6.Fig. 8 be in Fig. 6 rigging Impact direction with hang the A-A cutting structural representation of yard eye plate not when same plane.In addition, it should be noted that, in order to seem specification more, hang the not shown reinforcing pad of yard eye plate 130 in Fig. 6 and Fig. 8, yard eye plate 130 that hangs in Fig. 7 shows reinforcing pad 131 (hanging yard eye plate can have reinforcing pad also can not have reinforcing pad).
A kind of shackle positioning plate device embodiment that the utility model proposes, is suitable for being arranged on unloading and buckle, the shackle bearing pin 120 that described shackle comprises shackle body 110 and is arranged on the opening of shackle body 110 as shown in Figure 6 to 8.Described shackle positioning plate device comprises positioning plate group, described positioning plate group comprises the first positioning plate 10 (consulting Fig. 1 and Fig. 2) and the second positioning plate 20 (consulting Fig. 3 and Fig. 4), the first surface of described first positioning plate 10 is provided with protruding 11, the first surface of described second positioning plate is provided with groove 21; Described protruding 11 with described groove 21 suitable be spirally connected (being namely threaded connection); Described first positioning plate 10 is also provided with the first through hole 12 running through its second surface and described protruding 11 surfaces, the second surface of described first positioning plate 10 is relative with its first surface; Described second positioning plate 20 is also provided with the second through hole 22 running through its second surface and described groove surfaces, the second surface of described second positioning plate 20 is relative with its first surface; The aperture of described first through hole 12 and the aperture of described second through hole 22 all suitable with the diameter of described shackle latch 120, pass for described shackle latch 120.
In order to realize the object of the present embodiment better, progressively do change further below.
In the present embodiment, described protruding 11 can make the integral thickness of described positioning plate group with the stroke that is spirally connected of described groove 21, the A/F equaling described shackle body 110 (consults Fig. 7 or Fig. 8, for the width of the peristome 140 of clamping hanging code eye plate 130 and two cover positioning plate groups between described shackle body 110 two bottoms) with the half of hanging the difference of yard eye plate 130 thickness be arranged on described shackle bearing pin 120, or smaller.
In the present embodiment, the side between the first surface of described first positioning plate 10 and second surface is also provided with the first positioning plate handle 13; Side between the first surface of described second positioning plate and second surface is also provided with the second positioning plate handle 23, because the shape of the first positioning plate handle 13 and the second positioning plate handle 23 and installation site can be completely corresponding consistent, therefore only illustrate with Fig. 5 mono-.
Concrete, the side of described first positioning plate handle 13 and described first positioning plate 10 is by being threaded; Described second positioning plate handle 23 is same by being threaded with the side of described second positioning plate 20.
Due on the fields such as such as boats and ships for the volume of the shackle of lifting and weight relatively large, volume and the corresponding meeting of weight of the positioning plate group (first positioning plate 10 and the second positioning plate 20) therefore used in the present embodiment are larger, so described first positioning plate handle 13 and the second positioning plate handle 23 can use when carrying described first positioning plate 10 and the second positioning plate 20, to facilitate carrying; Also can regulate described protruding 11 and described groove 21 between be spirally connected stroke time use, regulate to facilitate.
During use, the present embodiment preferably uses the described positioning plate group of two covers, i.e. the first positioning plate group and the second positioning plate group; Described first positioning plate group and the second positioning plate group are installed on described shackle latch 120, and be positioned at the both sides of hanging yard eye plate 130 that described shackle latch 120 is installed, as shown in Fig. 7 or Fig. 8 (note all having comprised two cover positioning plate groups in Fig. 7 or Fig. 8, the first positioning plate 10 often in cover positioning plate group and the second positioning plate 20 have been illustrated integral).
The shackle positioning plate device that the present embodiment proposes goes for yard different the unloading of eye plate thickness of hanging that be different or that use of shackle body A/F and smashs, by regulating the stroke that is spirally connected often overlapping positioning plate group projection 11 and groove 21, the integral thickness often overlapping positioning plate group can be regulated, realize the position-limiting action hanging yard eye plate 130 to shackle latch 120 is installed; Make to hang yard eye plate 130 to avoid producing relative sliding with shackle latch 120, thus keep enough curved face contact, avoid, because stress raisers, load concentration and causing hang the problem that yard eye plate 130 and shackle bearing pin 120 damage, also reducing potential safety hazard simultaneously.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
