However, the plan to add a large-tonnage crane of 900 tons requires a one-time investment of about 12 million yuan, with only two target products, a low crane utilization rate and a high investment cost.
[0005] The second is to design and manufacture a non-standard rotating platform of at least 900 tons, drive the target product to rotate horizontally through the rotating platform, and then use a large-tonnage truck crane to lift it. However, the rotating platform occupies a large production area in the workshop, the number of target products is small, the utilization rate is low, and the height position of the truck crane in the workshop is limited.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0035] Example:
[0036] like Figure 1-6 As shown, in this embodiment, a beam hanging device is provided, including a main beam 1, an end beam 2, a short beam 3 and a slewing mechanism;
[0037] The short beam 3 is rotatably matched with the main beam 1 through a slewing mechanism. A rope seat assembly for connecting a rope is provided on the short beam 3. The connecting rope is used to connect a workpiece 16, namely, a steam generator.
[0038] A rope seat 14 for connecting a crane suspension rope is provided at one end of the main beam 1, and the other end is rotatably matched with the end beam 2, and the end beam 2 is vertically arranged relative to the main beam 1;
[0039] Both ends of the end beam 2 are provided with rope seats 14 for connecting the crane suspension ropes.
[0040] The lifting beam device of the present application has a double-layer rotatable structure, which is connected to two cranes with lifting capacities through the rope seat 14 of the main beam 1 and the rope seat 14 of the end beam 2. This can improve the overall lifting capacity. For example, the lifting capacities of a heavy-span 700-ton crane and a 350-ton double-trolley crane can be combined to increase the maximum heavy-span lifting capacity from 700 tons to 1,200 tons. Compared with the solution of adding a crane of more than 900 tons, it greatly saves costs.
[0041] The slewing mechanism is also provided. When adjusting the rotation, the crane is used to lift the beam device. The beam device lifts the workpiece. When the workpiece is close to the ground, the ground forklift and the sling can be used to pull one end of the workpiece. With the assistance of the forklift, the workpiece 16 can be pulled to achieve a 360-degree rotation and U-turn, and forward and reverse rotation can be achieved. Compared with the motor-driven automatic rotation solution, it also saves costs.
[0042] When the hanging beam device is stored, the bracket 17 can be used for support.
[0043] The slewing mechanism of the present application includes a hook fork 4, the upper end of the hook fork 4 is rotatably matched with the main beam 1, the lower end of the hook fork 4 extends into the short beam 3, and the lower end of the hook fork 4 is provided with a hanging shaft 5, which is connected to the short beam 3.
[0044] Specifically, the upper end of the hook fork 4 is a cylinder, and a thrust spherical roller bearing 6 and a slewing support bearing 7 are provided on the upper end of the hook fork 4 . The thrust spherical roller bearing 6 and the slewing support bearing 7 are provided on the main beam 1 .
[0045] Specifically, the side wall of the short beam 3 is provided with a through hole corresponding to the hanging shaft 5 , and the hanging shaft 5 is inserted and arranged along the radial direction of the hook fork 4 .
[0046] Specifically, the rope seat assembly includes a fixed shaft 8 passing through the short beam 3, and the side wall of the short beam 3 is provided with a rope seat body 9, the rope seat body 9 cooperates with the fixed shaft 8, the rope seat body 9 is provided with a rope groove, and a bolt member 10 is provided at the notch of the rope groove, and one end of the bolt member 10 is connected to the side wall of the short beam 3.
[0047] Specifically, the short beam 3 is in the shape of an inverted triangle structure, and the rope seat assemblies are symmetrically arranged at the two ends of the bottom of the short beam 3 .
[0048] The hanging rope connected to the hanging rope seat assembly of the present application adopts a hanging rope scheme of long rope 18 and short rope 19. Combined with the overall height of the workshop, the target product country and the diameter of the No. 1 evaporator, the height of the cross-domain obstacle, the height of the hanging beam itself, the safety angle of the hanging rope and other comprehensive factors are analyzed to draw a simulation diagram of the hanging rope setting. At the same time, in order to reduce the difficulty of hanging the hanging rope at high altitude, the hanging rope is finally set to a length configuration scheme of a 5m short rope 19 and a 16m long rope 18. The hanging rope connection is completed by a shackle 20 above the side of the workpiece 16 and in a position accessible by a forklift, which not only facilitates the connection of the hanging rope, but also avoids the shackle from crushing the surface of the workpiece 16. Due to the limitation of the lifting height requirement, a very long hanging rope cannot be used, and the hanging beam is lowered to the ground near the side of the workpiece 16 for hooking; if a shorter hanging rope is used, it is difficult to hang it on the hook on the other side because the hanging rope is bulky. Therefore, the hanging rope on the hanging rope seat assembly of the present application is designed as a combination of a long rope 18 and a short rope 19.
[0049] Specifically, a matching groove 11 is provided at the other end of the main beam 1 , and the end beam 2 matches with the matching groove 11 .
[0050] Specifically, a rotating shaft 12 is provided at the other end of the main beam 1 , one end of the rotating shaft 12 is located in the matching groove 11 , and a rotating groove 13 matching with the rotating shaft 12 is provided at the middle position of the end beam 2 .
[0051] Specifically, the rope seat 14 is provided with a plurality of pulley members.
[0052] Specifically, balance and eccentric weight indicator needles 15 are provided on the main beam 1 and the short beam 3, which are used to observe the balance state of the lifting.
[0053] To sum up, the structure of the present application has the effects of low investment and excellent lifting effect. Combined with the company's existing two cranes with 700 tons and 350 tons double trolleys, the lifting capacity is increased to 1,200 tons, which not only meets the lifting needs of the products, but also improves the large-scale lifting capacity of the factory.
[0054] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
