Description

Technical Field

[0001] The invention belongs to the technical field of lifting auxiliary equipment, and in particular relates to a lifting device and method for a vertical funnel. Background Art

[0002] The vertical funnel plays a key role in the production process of vertical centrifugal rollers. Usually, a hoist is required to lift the horizontal vertical funnel to a vertical state and lift it to the mold entrance through the lifting ears on the left and right sides of the vertical funnel. The existing hoist beam is composed of two welded channel steels. However, after lifting the vertical funnel many times, the welded split hoist beam is very likely to produce stress fatigue inside and at the welding position, resulting in deformation and cracks. On-site operators can only check whether the appearance is abnormal with the naked eye, and cannot effectively inspect the inside of the hoist beam. Therefore, during the process of lifting the vertical funnel, the hoist beam may break, causing the vertical funnel to fall off, posing a serious safety hazard. If the vertical funnel falls off, it will not only cause the baking process to be interrupted, resulting in the forced activation of the spare funnel that does not meet the temperature control requirements, causing quality problems such as the decrease in the bonding strength of the roller coating, but will also directly endanger the personal safety of operators who perform pipe inversion and pipe lowering operations at close range in the lifting area, posing a serious risk of personal injury.

[0003] Therefore, there is a need for a hoisting device and method for a vertical hopper that has higher structural strength and can effectively ensure operational safety. Summary of the invention

[0004] The object of the present invention is to provide a hoisting device and method for a vertical funnel, which has higher structural strength and can effectively ensure the safety of hoisting operation.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: A lifting device for a vertical funnel comprises an integrally formed crossbeam, a lifting portion arranged at the top center of the crossbeam and adapted to lifting equipment, support plates respectively arranged vertically at the left and right ends of the crossbeam and extending to the bottom thereof, connecting plates respectively arranged horizontally and vertically at the left and right ends of the bottom of the crossbeam, and a hanging component connected to the two connecting plates at the bottom of the crossbeam through "U"-shaped connecting pieces, and the two hanging components are respectively adapted to the lifting ears on the left and right sides of the vertical funnel; one end of the connecting plate close to the support plate on the same side thereof abuts against the inner side wall of the support plate, and the connecting plate is provided with a plurality of through holes adapted to the "U"-shaped connecting piece uniformly spaced along its length direction, and the "U"-shaped connecting piece can be installed on any through hole of the connecting plate by a locking bolt.

[0006] A further improvement of the technical solution of the present invention is that the lifting part includes a lifting plate arranged at the center position of the top of the beam, a lifting hole adapted for lifting equipment opened through the thickness direction of the lifting plate, and a group of reinforcing ribs symmetrically arranged on the front and rear sides of the lifting plate.

[0007] A further improvement of the technical solution of the present invention lies in that: the lifting hole has an inverted trapezoidal profile with a wider upper part and a narrower lower part, and its upper and lower bottom edges are respectively formed by a single continuous arc, and the radian of the upper bottom edge arc is greater than that of the lower bottom edge arc; the reinforcing rib group includes two vertical rib strips symmetrically distributed on the left and right sides of the lifting hole.

[0008] A further improvement of the technical solution of the present invention lies in that: the support plate is an integrally formed structure, which includes a vertical plate fittingly connected to the end face of the cross beam and a support located below the end of the cross beam and connected to the vertical plate.

[0009] A further improvement of the technical solution of the present invention lies in that: the upper end of the support is connected to the bottom of the vertical plate, and its lower end is formed with an inverted "V" - shaped bifurcation.

[0010] A further improvement of the technical solution of the present invention lies in that: the suspension member includes a rotating sling connected to the connecting plate through a "U" - shaped connecting member and a hook suspended on the rotating sling through a chain, wherein the hook is adapted to the lifting lugs of the vertical funnel.

[0011] A further improvement of the technical solution of the present invention lies in that: the rotating sling adopts a butterfly buckle structure, including two semi - circular members arranged corresponding to each other up and down, and the upper semi - circular member is suspended on the "U" - shaped connecting member, and the lower semi - circular member is hinged to the upper semi - circular member through a rotating shaft; the chain is suspended on the lower semi - circular member of the rotating sling.

[0012] A further improvement of the technical solution of the present invention lies in that: the chain lengths of the two suspension members are the same.

[0013] A hoisting method for a vertical funnel, using a hoisting device to hoist the vertical funnel, includes the following steps: Step S1: According to the distance between the lifting lugs on the left and right sides of the vertical funnel, select the through - hole positions on the two connecting plates of the cross beam that are adapted to the distance between the two lifting lugs; Step S2: According to the through - hole positions on the two connecting plates selected in Step S1, use locking bolts to respectively fix the two "U" - shaped connecting members connected with the suspension members on the through - holes of the two connecting plates, ensuring that the two suspension members are symmetrically distributed on the cross beam; Step S3: Align the hook of the lifting equipment with the lifting hole on the lifting plate at the top of the cross beam, and use the self - locking characteristic of the inverted trapezoidal profile of the lifting hole to hook the hook of the lifting equipment into the lifting hole of the lifting plate; Step S4: Hook the hooks of the two suspension members into the lifting lugs on the left and right sides of the vertical funnel respectively; Step S5: Start the lifting equipment to lift the horizontally placed vertical funnel to a vertical state and hoist it to the target position. As the vertical funnel swings during the hoisting process, the chains of the two suspension members swing adaptively around the rotating shaft through the lower semi - circular member of the rotating sling; Step S6: After the vertical funnel completes the operation, the hoisting equipment hoists it back to its original position and slowly lowers it to a horizontal state, ensuring that the inverted "V"-shaped supports on the support plates at both left and right ends of the crossbeam are in stable contact with the ground. Then, the hooks of the two suspension components are respectively detached from the lifting lugs on the left and right sides of the vertical funnel, and the hoisting operation ends.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is as follows: The hoisting device and method for a vertical funnel of the present invention have higher structural strength and can effectively ensure the safety of hoisting operations.

[0015] The crossbeam adopted by the present invention is of an integrally formed structure, with higher strength. Support plates are vertically arranged at the left and right ends of the crossbeam respectively. The vertical plates of the support plates are adhesively connected to the end faces of the crossbeam. Its supports are located below the ends of the crossbeam, and the lower ends of the supports form an inverted "V" - shaped fork, and the fork design increases the grounding area and can serve as a stable fulcrum when landing.

[0016] The present invention adopts connecting plates that are horizontally and perpendicularly arranged at the left and right ends of the bottom of the crossbeam respectively, and one end of each connecting plate close to the support plate on its same side abuts against the inner side wall of the support plate, forming a support structure, effectively improving the stability of the overall structure.

[0017] The multi - through - hole design on the two connecting plates adopted by the present invention, combined with U - shaped connectors, allows for flexible horizontal adjustment of the positions of the two suspension components, can adapt to vertical funnels with different lifting lug spacings, and reduces the need for customized equipment.

[0018] The rotating lifting rings adopted by the present invention can swing adaptively. The rotating lifting rings with butterfly - buckle hinge structures enable the chains to adjust the angle with the swing of the vertical funnel during the hoisting process, avoiding chain distortion or stress concentration caused by inertial forces and enhancing the adaptability under complex working conditions.

[0019] The lifting holes adopted by the present invention have an inverted trapezoidal profile with a wider upper part and a narrower lower part, and the upper and lower bottom edges are respectively composed of a single continuous arc. By geometric self - locking, the displacement of the hook of the hoisting equipment is restricted, and in cooperation with the reinforcing rib group of the lifting plate to disperse stress, the risk of unhooking is significantly reduced.
