[0002] In the production of metal structures, it has always been a difficult problem to hoist and turn over large drums, especially when the weight exceeds the common mobile wheeled cranes, and only the factory gantry cranes can be used. In the past, the hoisting of large drums was carried out by lifting with two cranes first, and then one crane remained stationary after reaching the required height, and the other crane began to descend to complete the turning. This method requires the assistance of a wheeled crane or crawler crane of more than 300T. During the implementation process, the imbalance coefficient of the two machines and the lifting angle must also be considered. This method not only has a low safety factor but also has a high cost for renting a crane, especially in the mass production process. It is even more uneconomical.

The lug plate 5 is welded to the column 3 and extends outward from the column.

[0021] The lifting lug 9 is used to connect with the lifting equipment; the side flip lug 7 is used to connect with the rotating shaft 4 of the flip bracket 6. The number of the lifting lugs 9 is two. The number of the side flip lugs 7 is two.

[0022] Embodiment 1:

[0023] In the production of metal structures, it has always been a difficult problem to turn over large drums, especially when the weight exceeds the common mobile wheeled cranes, and only the factory gantry crane can be used. In the past, the large drum turning over hoisting was carried out by two cranes to lift up first, and then one crane remained stationary after reaching the required height, and the other crane began to descend to complete the turning. This method requires the assistance of a wheeled crane or crawler crane of more than 300T. During the implementation process, the imbalance coefficient of the two machines and the lifting angle must also be considered. This method not only has a low safety factor but also has a high cost for renting a crane, especially in the mass production process. It is even more uneconomical. Therefore, an auxiliary tooling is invented to complete the turning under the lifting of a lifting equipment. The specific plan is as follows:

[0024] A large-scale reel turning device, a turning bracket 6, a lug plate 5 is welded on the turning bracket 6, a rotating shaft 4 is installed on the lug plate 5, the two sides are symmetrical, the reel body 8 can rotate under the support of the rotating shaft 4, and the side turning lugs 7 match the rotating shaft 4; deep grooves are provided on both sides of the rotating shaft 4, and the rotating shaft 4 can be fixed by a shaft stop plate. In actual operation, the reel body 8 is first hoisted horizontally to a height that matches the turning bracket 6 by a lifting device, and then the side turning lugs 7 of the brake disc on the reel body 8 are matched with the turning bracket 6, and the side turning lugs 7 are hung on the turning bracket 6. The rotating shaft 4 on it is a double lifting point during horizontal lifting. When the two are matched, the lifting point at the end that cooperates with the flip bracket 6 will be removed, leaving only the lifting point of the spline side lifting ear 9. At this time, one end of the drum body 8 is at the flip bracket 6 at the other end of the lifting equipment. At this time, the drum body 8 begins to flip, and the lifting point of the lifting ear 9 on the side of the lifting equipment begins to rise, and the hoisting equipment on the lifting point also gradually moves toward the flip bracket 6 to ensure the stability of the entire lifting process, and then until the drum body 8 stands on the flip bracket 6, the process of inserting the drum shaft 10 into the drum body 8 can be started.

[0025] The working principle of this device:

[0026] The main body of the flip bracket is a welded steel structure. The base part bears the load, the columns and beams transfer the load, and the lifting ears and rotating shafts are the main force-bearing structures, which are in direct contact with the drum body.

[0027] When turning over, the double lifting points are lifted horizontally to the matching height of the flip bracket, and the side flip lifting ears are hung on the rotating shaft on the flip bracket to ensure good cooperation. After the drum body is stable, the lifting point close to the flip bracket side is removed, and the lifting point on the lifting ear side is retained.

[0028] When turning over, the lifting point at the lifting eye starts to rise and the lifting trolley perpendicular to the lifting point starts to move toward the turning bracket until the entire drum body starts to stand vertically and then starts to insert the drum shaft. After completion, the lifting point starts to drop and turns the entire assembly to a horizontal state, completing the entire turning process.

[0029] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
