Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting balance beam technology, specifically to a multi-functional rolling mill stand hoisting balance beam. Background Technology
[0002] The mill archway is one of the key components in the manufacturing of steel rolling equipment. Its weight is generally around 40 to 400 tons and its height is generally around 8 to 16 meters. When the mill is trial-assembled in the manufacturing plant and finally installed on the installation site, the mill archway must be in the final working state. Since the archway is a heavy and tall sheet-like component, there are several difficulties in the erection process.
[0003] In general, the lifting capacity of a single overhead crane in a workshop cannot meet the requirements for hoisting the rolling mill frame. Even with the use of two cranes, the space height still cannot meet the hoisting requirements. Furthermore, under special transportation conditions, the rolling mill frame needs to be hoisted from a horizontal position to a vertical position. Utility Model Content
[0004] Technical problems to be solved
[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a multi-functional rolling mill stand hoisting balance beam, which effectively solves the problems of existing technologies where single and double-stand hoisting cannot meet hoisting requirements, and where the rolling mill stand requires vertical adjustment.
[0006] Technical solution
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] This utility model provides a multi-functional rolling mill stand hoisting balance beam, including a balance beam, which is composed of two sets of plate beams spliced together, and the two sets of plate beams are fixedly connected on both sides by limiting plugs. A rolling mill stand is set in the middle of the balance beam. Adjustable lifting lug assemblies are fitted on both sides of the balance beam. Each set of adjustable lifting lug assemblies includes an adjustable lifting lug and a hanging rod. A central groove is opened in the middle of the top of the adjustable lifting lug, and the hanging rod is set in the central groove. A crane hook is fitted on the outside of the hanging rod. A limiting block is fixed in the middle of the top of the balance beam. A rotary power assembly is set on the outer side of one end of the balance beam. The rotary power assembly includes a drive motor and a rotating arm set at the output end of the drive motor. The end of the rotating arm is fixedly connected to a connector.
[0009] Furthermore, the upper and lower ends of the limiting plugs on both the left and right sides are trapezoidal structures, and the outer diameter of the plugs is smaller than the inner diameter of the adjustable lugs.
[0010] Furthermore, a flange structure is fixed to the top of the rolling mill stand, and the connector is a combination of a flange and locking bolts. The connector is fixedly connected to the flange at the rolling mill stand by bolts.
[0011] Furthermore, the size of the limiting block is adapted to the internal dimensions of the rolling mill stand, and the rolling mill stand is inserted into the middle groove of the balance beam.
[0012] Furthermore, the flange at the top of the rolling mill stand has a square structure, and the central hollow grooves of the flange are distributed in an arc on the rolling mill stand, with at least four sets.
[0013] Furthermore, the maximum deflection angle of the drive motor is 60°.
[0014] Beneficial effects
[0015] The technical solution provided by this utility model has the following advantages compared with the known public technology:
[0016] This utility model features a balance beam structure composed of two sets of plate beams and limiting blocks. During use, the mill stand is easily fixed and limited by the limiting block structure in the middle. The balance beam structure lifts the mill stand to a specified height. The two sets of adjustable lifting lug assemblies on both sides of the balance beam can firstly increase the weight of a single lift, and secondly improve the stability of the lift. The limiting plug structure on both sides can limit the position of the adjustable lifting lugs to prevent them from shifting or swaying, thus improving the stability of the lift.
[0017] In this device, through the set rotational power component, the operator can first fix the rotating arm-flange-rolling mill stand with bolts, and then drive the rotating arm-rolling mill stand to deflect it through the drive motor structure, turning the tilted rolling mill stand structure to a vertical state, which meets the function of rapid operation. At the same time, the rigid connection method makes it easy for the user to lift the height and improves safety. Attached Figure Description
