SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model aims at providing an improve work efficiency, repeatedly usable avoids causing wasting of resources's stern axle steel casting hoisting platform.
In order to achieve the above object, the utility model discloses a technical scheme that stern axle steel-casting piece hoisting platform adopted is:
the utility model provides a stern shaft steel casting hoist and mount platform, includes the layer board, and the layer board top surface is provided with a pair of otic placode at least, and the otic placode is next to the layer board edge, and the layer board salient is used for bearing stern shaft steel casting in the position of otic placode, and the edge of layer board does not salient in the outer peripheral face of stern shaft steel casting, and the layer board is provided with a plurality of stop gear for prevent layer board and stern shaft steel casting relative motion take place. The stern shaft steel casting is entered in a vertical state by a forklift, during hoisting, the lug plate is inserted into the inner cavity of the stern shaft steel casting, one lug plate is ensured to be positioned at the highest end, the supporting plate is abutted against the end surface of the stern shaft steel casting, the supporting plate is prevented from shaking by the limiting mechanism, the hoisting equipment is used for turning over the stern shaft steel casting by utilizing the lug plate positioned at the highest end, and then all the lug plates are used for hoisting the stern shaft steel casting.
Preferably, the limiting mechanism comprises a nut welded on the top surface of the supporting plate, and the nut is in threaded connection with a limiting bolt.
Preferably, the limiting mechanism comprises a threaded sleeve welded on the side wall of the ear plate, and the threaded sleeve is in threaded connection with a limiting screw.
Preferably, one end of the limiting screw rod facing the center of the supporting plate is provided with a handle.
Preferably, the supporting plate comprises a long plate, short plates are welded on two sides of the long plate, and edges on two sides of the long plate and edges on outer sides of the short plates are located on the same circle.
Preferably, the middle part of the long plate is provided with a through hole.
Compared with the prior art, the utility model, have following advantage:
make stern axle steel-casting and layer board form a whole through stop gear, stand up stern axle steel-casting earlier, then lift by crane, the transfer in-process, stern axle steel-casting does not rock, and the security is high, the assembly of the stern axle steel-casting of being convenient for simultaneously, and the layer board is demolishd to the assembly completion back of stern axle steel-casting, does not have the epilogue work, and work efficiency is high, and can used repeatedly resources are saved.
Drawings
Fig. 1 is a schematic structural view of a stern shaft steel casting hoisting platform of the present invention;
fig. 2 is a top view of the stern shaft steel casting hoisting platform of the present invention;
fig. 3 is a schematic structural diagram of another type of limiting mechanism.
The device comprises a supporting plate 1, a long plate 11, a short plate 12, a through hole 13, a lug plate 2, a limiting mechanism 3, a nut 31, a limiting bolt 32, a threaded sleeve 41, a limiting screw rod 42 and a handle 43.
Detailed Description
The present invention will be further clarified by the following description in conjunction with the accompanying drawings, which are to be understood as illustrative only and not as limiting the scope of the invention, and modifications of the various equivalent forms of the invention by those skilled in the art after reading the present invention are within the scope defined by the appended claims.
As shown in fig. 1-2, a stern shaft steel casting hoisting platform comprises a supporting plate 1, wherein the supporting plate comprises a long plate 11, short plates 12 which are symmetrically welded on two sides of the long plate, two side edges of the long plate and outer side edges of the short plates are located on the same circle, the supporting plate is formed by welding the long plate and the short plates in a splicing mode, the use of plates can be reduced, the manufacturing cost is reduced, a through hole 13 is formed in the center of the long plate, a plumb bob penetrates out of the through hole to adjust the stern shaft steel casting to be in a vertical state when the stern shaft steel casting is assembled, two pairs of lug plates 2 which are arranged in a cross mode are welded on the top surface of the supporting plate, the lug plates are close to arc-shaped edges of the supporting plate, the portion, protruding out of the lug plates, is used for bearing the stern shaft steel casting, the edges of the supporting plate do not protrude out of the outer peripheral surface of the stern shaft steel casting, the supporting plate is prevented from interfering with the bottom surface when the supporting plate is sleeved with the stern shaft steel casting in a vertical state, four limiting mechanisms 3 which are arranged and abut against the center of the through hole and are distributed circumferentially, the top surface of the supporting plate, the limiting mechanism comprises nuts 31 which are welded on the top surface, the top surface of the supporting plate, the limiting bolts 32 are connected with the nuts, and the nuts are connected with the limiting bolts, and the limiting mechanisms prevent the relative movement of the supporting plate.
As shown in fig. 3, the limiting mechanism is another type of limiting mechanism, and includes a threaded sleeve 41 welded to the side wall of the lug plate, the threaded sleeve is connected with a limiting screw rod 42 in a threaded manner, one end of the limiting screw rod facing the center of the support plate is welded with a handle 43, and the limiting screw rod abuts against the stern shaft steel casting to prevent the support plate and the stern shaft steel casting from moving relatively.
The utility model discloses a concrete working process and principle: the method comprises the steps of turning over a stern shaft steel casting, inserting four lug plates into an inner cavity of the stern shaft steel casting, keeping the pair of lug plates in a vertical state, screwing a limiting bolt (or a limiting screw) until the limiting bolt abuts against the inner peripheral wall of the stern shaft steel casting after a supporting plate abuts against the end face of the stern shaft steel casting, limiting relative motion between the stern shaft steel casting and the supporting plate, penetrating a steel wire through the lug plate on the uppermost side, turning the stern shaft steel casting to a flat state, lifting the stern shaft steel casting by using the four lug plates, lifting the stern shaft steel casting to a stern section for assembly, loosening the limiting bolt after assembly is finished, withdrawing the supporting plate, avoiding subsequent work such as polishing and repair welding, and the like.
