Overturning and hoisting tool for large tube plate forging
Technical Field
The utility model relates to a large-scale tube sheet forging is with upset and lift by crane frock belongs to hoist technical field.
Background
In the tube plate manufacturing process for large-scale equipment, multiple times of hoisting and overturning are needed due to processing and manufacturing, but due to the requirements of some equipment, any hoisting lifting lug cannot be welded on the excircle of the tube plate, and the welding strength cannot be ensured. Moreover, because large-scale tube sheet forging is great, the length is shorter usually, is difficult to bind, in case there is any danger that drops in the hoist and mount process, not only can directly damage the work piece, still can threaten workman life safety, consequently also be difficult to adopt ordinary wire rope direct contact forging to lift by crane. In addition, due to the reasons of materials of the large tube plate forging, scratches and ferrite pollution are prevented from being generated on the surface of the large tube plate forging in the hoisting process.

Preferably, the turnover and hoisting tool for the large tube plate forging is characterized in that the upper edge and the lower edge of the arc plate are both provided with outward flanges, and the rib plate is connected to the flanges through bolts.
Preferably, the clamping buckle reinforcing rib is further arranged between the clamping buckle and the arc plate.
Preferably, the arc plate is further provided with a long circular hole parallel to the arc plate.
Preferably, the number of the arc assemblies is two or four in the turnover and hoisting tool for the large tube plate forging.
Preferably, the product connecting surface of the arc plate is also provided with a rubber plate.
Preferably, the lifting lug is semicircular and is provided with a plurality of lifting holes.
The utility model discloses the beneficial effect who reaches:
the utility model discloses can satisfy the great large-scale tube sheet forging of quality upset and lift by crane fixedly under the condition that does not harm the work piece excircle. After the workpiece is fixed, safety and reliability can be ensured to some extent, and the protective rib plate can prevent the workpiece from slipping from the arc plate.
Because there is certain clearance between the adjacent circular arc subassembly, consequently can satisfy the user demand that the product external diameter changes in certain extent, promoted adaptability. The rubber sheet can be placed on the outer surface of a product, and the rubber sheets with different thicknesses can be placed in practical application, so that workpieces of different models can be met.

Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 to 5: the embodiment discloses a turning and lifting tool for a large-scale tube plate forging, which comprises at least two end-to-end arc assemblies, wherein each arc assembly comprises an arc plate 1, a lifting lug 3 and buckles 2 arranged at two ends of the arc plate 1, the buckles 2 are provided with a plurality of through holes for penetrating bolts, the lifting lugs 3 are connected to the side part of the arc plate 1, and the upper edge and the lower edge of the arc plate 1 are also provided with protective rib plates 4; when the circular arc components are connected, the connected circular arc components are connected through the buckles 2, the buckles 2 are connected through the bolts, all the circular arc components can form a closed cylinder, and the bolts between the fastening buckles 2 can fasten the large tube plate forging piece placed inside. As shown in fig. 4: the lifting lug 3 is preferably semicircular, the lifting lug 3 is provided with a plurality of lifting holes, and the connecting lines of all the lifting holes are also distributed in an arc shape, so that the distance between the lifting point and the arc plate 1 is convenient to adjust, and the deviation between the lifting point and the center of gravity of a product is also convenient to adjust.
With reference to fig. 4 and 5: the connection mode of the protective rib plate 4 and the arc plate 1 is as follows: the protective rib plate 4 is also provided with a through hole, and the rib plate 4 is connected to the upper edge and the lower edge of the arc plate 1 through bolts. Specifically, the upper edge and the lower edge of the arc plate 1 are both provided with outward flanges 11, and the rib plate 4 is connected to the flanges 11 through bolts. The flanging 11 can be used for installing the protective rib plate 4 and can also play a role in reinforcing the strength of the whole circular arc plate 1.
Still be equipped with buckle strengthening rib 21 between buckle 2 and the circular arc board 1 of this embodiment, strengthening rib 21 is used for avoiding the bolt to draw buckle 2 to warp, plays tensile effect, and the relation between buckle 2, circular arc board 1 and the buckle strengthening rib 21 is the welding best to all adopt full weld best.
The circular arc plate 1 is also provided with an oblong hole 13 parallel to the circular arc plate 1, and the oblong hole 13 can reduce the mass of the whole circular arc plate 1 and is convenient for observing the internal workpiece through the oblong hole 13.
The number of the arc assemblies in the embodiment can be two or four, fig. 1 shows a turning and hoisting tool consisting of four arc assemblies, wherein each arc assembly is 90 degrees, fig. 2 shows a semicircular arc assembly, and two arc assemblies can form the turning and hoisting tool.
With reference to fig. 3 and 4, the product has different sizes or the product is processed and manufactured with different errors, so as to meet the requirements of turning and lifting products with various sizes.
During the use, all circular arc subassemblies are end to end connection in proper order, and the bolt through between the adjacent buckle 3 is fixed with the circular arc subassembly, and along with the continuous fastening of bolt, the circular arc board 1 constantly forms to the work piece and presss from both sides tightly, fixes the work piece through the frictional force of pressing from both sides tight production. Because the upper edge and the lower edge of the arc plate 1 are also provided with the protective rib plates 4, even if friction occurs between the workpiece and the arc plate 1, the protective rib plates 4 can block the workpiece, and the workpiece is prevented from directly slipping from the arc plate 1. When the lifting hook is lifted or turned over, the lifting hook is connected in the lifting hole on the lifting lug 3, and the workpiece in the embodiment and the inside is lifted.
The utility model discloses can satisfy the great large-scale tube sheet forging of quality upset and lift by crane fixedly under the condition that does not harm the work piece excircle. After the workpiece is fixed, safety and reliability can be ensured to some extent, and the protective rib plates 4 can prevent the workpiece from slipping from the arc plate 1.
Because there is certain clearance between the adjacent circular arc subassembly, consequently can satisfy the user demand that the product external diameter changes in certain extent, promoted adaptability. The rubber sheet can be placed on the outer surface of a product, and the rubber sheets with different thicknesses can be placed in practical application, so that workpieces of different models can be met.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
