Description

Technical Field

[0001] This invention relates to the field of cranes, specifically a crane for processing steel liner plates. Background Technology

[0002] Overhead cranes (also known as gantry cranes or overhead cranes) are key pieces of equipment used for material hoisting and handling in industrial production, and are widely used in factories, warehouses, ports, construction sites, and other scenarios. They achieve horizontal movement through track running and complete vertical lifting and lowering in conjunction with a lifting mechanism, enabling efficient handling of heavy objects (ranging from a few tons to hundreds of tons) and significantly improving operational efficiency.

[0003] The processing of steel lining plates (steel plates used for structural protection or lining) involves cutting, welding, forming, grinding and other processes. In the steel lining plate processing scenario, the crane is the core equipment for realizing the handling of steel plates and the flow of workstations. Its performance directly affects the processing efficiency, workpiece quality and production safety.

[0004] In existing technology, during steel liner processing, a certain number of workers move around the workshop to process the steel liners. When a crane lifts and transports the steel liners, its hooks are equipped with electromagnetic adsorption devices. These devices magnetically attract and fix the steel liners in place. The crane then moves, causing the steel liners to shift. The crane is usually connected to the hooks via steel cables, which are perpendicular to each other. During the displacement of the steel liners by the crane, the steel liners are supported and suspended by the steel cables. Due to inertia, steel lining plates can sway. During this swaying, the horizontal or vertical swinging can directly impact nearby workers. Especially when the steel lining plates are large and heavy, even a slight collision can cause serious injuries such as fractures or crushing. If the swaying amplitude is too large, it may squeeze people between the steel lining plates and the walls or equipment, causing fatal injuries. The safety hazards of swaying steel lining plates are sudden and have a chain reaction effect. At best, it can cause equipment damage and production interruption; at worst, it can lead to serious accidents such as casualties, fires, and explosions. Summary of the Invention

[0034] Please see Figure 1 - Figure 3 Auxiliary plates 5 are installed on the outer walls of both sets of movable seats 4, and the inner walls of the two sets of auxiliary plates 5 are movably connected to the outer walls of the two sets of support frames 1 respectively. The cross-section of the two sets of auxiliary plates 5 is "C" shaped. The two sets of movable seats 4 move at the upper ends of the two sets of support frames 1 respectively, which drives the two sets of auxiliary plates 5 to move on one side of the two sets of support frames 1 respectively. The two sets of auxiliary plates 5 provide auxiliary guidance for the movement of the two sets of movable seats 4 respectively, so as to avoid the two sets of movable seats 4 from shifting at the upper ends of the two sets of support frames 1 respectively.

[0035] Please see Figure 2 - Figure 6A second motor 13 is mounted on the upper end of the movable base 12. The second motor 13 is a dual-axis motor. A drive shaft 14 is installed at the output end of the second motor 13. Connecting shafts 15 are symmetrically mounted on the upper end of the movable base 12. The two sets of connecting shafts 15 are respectively connected to the two ends of the drive shaft 14 by toothed synchronous belts. When the second motor 13 starts, the second motor 13 drives the drive shaft 14 to rotate. The two ends of the drive shaft 14 are respectively connected to the two sets of connecting shafts 15 by toothed synchronous belts. Therefore, the two sets of connecting shafts 15 rotate synchronously.

[0036] Please see Figure 2 - Figure 6 Each of the two sets of connecting shafts 15 has a second roller 16 mounted on its outer wall, and the outer walls of the two sets of second rollers 16 are movably connected to the outer wall of the movable frame 9. The upper end of the movable frame 9 has multiple sets of second sliding grooves 10. The outer walls of the two sets of second rollers 16 are each equipped with multiple sets of limiting rings 17, and the multiple sets of limiting rings 17 are movably connected to the multiple sets of second sliding grooves 10. When the two sets of connecting shafts 15 rotate, they drive the two sets of second rollers 16 to rotate, which in turn drives the multiple sets of limiting rings 17 to rotate. The two sets of second rollers 16 rotate at the upper end of the movable frame 9, causing the movable seat 12 to move. The multiple sets of limiting rings 17 move within the multiple sets of second sliding grooves 10, and the multiple sets of limiting rings 17 provide auxiliary guidance for the movement of the two sets of second rollers 16.

[0037] Please see Figure 3 - Figure 8 The outer wall of the movable frame 9 is symmetrically provided with third sliding grooves 40, and the inner wall of the movable seat 12 is symmetrically provided with movable boxes 18.

When the movable seat 12 moves, it drives the two sets of movable boxes 18 to move inside the two sets of third sliding grooves 40 respectively, thereby driving the multiple sets of third rollers 19 to rotate, improving the moving efficiency of the movable seat 12. The limit post 20 moves inside the limit groove 11, improving the stability of the movable seat 12 in the moving state.

[0038] Please see Figure 9 - Figure 11 The mounting base 21 is equipped with a third motor 22, and one end of the first movable shaft 23 is connected to the output end of the third motor 22. The bottom end of the mounting base 21 is equipped with a first steering wheel 29, and the inner wall of the first steering wheel 29 is movably connected to the outer wall of the first steel cable 30.

[0039] Please see Figure 9 - Figure 11 Multiple steering columns 33 are installed at the bottom of the mounting base 21. Each set of steering columns 33 has a fixed plate 34 installed at its bottom. The outer walls of the two sets of second steel cables 36 are movably connected to the outer walls of the multiple sets of steering columns 33. The multiple sets of steering columns 33 cooperate to change the moving direction of the two sets of second steel cables 36.

[0040] Please see Figure 9 - Figure 11 The bottom end of the limiting post 20 is symmetrically equipped with second steering wheels 35, and the inner walls of the two sets of second steering wheels 35 are movably connected to the outer walls of the two sets of second steel cables 36 respectively. When the second steel cables 36 are moving, the two sets of second steering wheels 35 respectively turn the two sets of second steel cables 36.

[0041] Please see Figure 1 - Figure 11 A set of support columns 2 are equipped with a remote control device on their outer wall. The remote control device is connected to the first motor 6, the second motor 13 and the third motor 22. The remote control device controls the first motor 6, the second motor 13 and the third motor 22 to turn on or off respectively.

[0042] The working principle of this invention is as follows: In the steel liner processing operation, when the operator uses the crane to transport the steel liner, the electromagnetic adsorption device electromagnetically adsorbs the steel liner, fixing it to the bottom of the electromagnetic adsorption device. Then, the operator starts two sets of first motors 6 and second motors 13 via a remote control device. The two sets of first motors 6 drive two sets of limiting shafts 7 to rotate. The multiple sets of limiting shafts 7 are connected by toothed synchronous belts, so the multiple sets of limiting shafts 7 rotate synchronously, thereby driving multiple sets of first rollers 8 to rotate. This causes the multiple sets of first rollers 8 to move inside the two sets of first sliding grooves 3, thereby driving the two sets of movable seats 4 to move on the upper ends of the two sets of support frames 1, and further driving the two sets of auxiliary plates 5 to move on one side of the two sets of support frames 1. The two sets of auxiliary plates 5 provide auxiliary guidance for the movement of the two sets of movable seats 4, preventing the two sets of movable seats 4 from deviating on the upper ends of the two sets of support frames 1, and improving the safety of the two sets of movable seats 4 in the moving state. When the two sets of movable seats 4 move, they drive the movable frame 9 to move as well. At the same time, the second motor 13 starts. The second motor 13 is a dual-axis motor. The second motor 13 drives the drive shaft 14 to rotate. The two ends of the drive shaft 14 are connected to the two sets of connecting shafts 15 through toothed synchronous belts. Therefore, the two sets of connecting shafts 15 rotate synchronously, thereby driving the two sets of second rollers 16 to rotate, which in turn drives the multiple sets of limit rings 17 to rotate. The two sets of second rollers 16 rotate on the upper end of the movable frame 9, driving the movable seat 12 to move. The multiple sets of limit rings 17 move within the multiple sets of second slide grooves 10. The multiple sets of limit rings 17 provide auxiliary guidance for the movement of the two sets of second rollers 16, preventing the two sets of second rollers 16 from deviating on the upper end of the movable frame 9, thus improving the safety of the movable seat 12 in the moving state. When the movable seat 12 moves, it drives the two sets of movable boxes 18 to move inside the two sets of third slide grooves 40 respectively, thereby driving multiple sets of third rollers 19 to rotate, further improving the moving efficiency of the movable seat 12. When the movable frame 9 and the movable seat 12 are in a moving state, the hook 28 moves. The staff controls the movement of the movable frame 9 and the movable seat 12 through the remote control device. After the hook 28 moves to the upper area of ​​the electromagnetic adsorption device, the staff turns off the two sets of first motors 6 and second motors 13. When the hook 28 is suspended in the upper area of ​​the electromagnetic adsorption device, when the staff starts the third motor 22 through the remote control device, the third motor 22 drives the first movable shaft 23 to rotate, thereby driving the first take-up roller 24 to rotate. The first movable shaft 23 and the second movable shaft 25 are connected by a toothed synchronous belt, so the second movable shaft 25 rotates synchronously with the first movable shaft. When the first movable shaft 23 rotates, it drives the first take-up roller 24 to rotate, causing the first steel cable 30, which is wrapped around the outer end of the first take-up roller 24, to be released from the first cable outlet 38. Then, the first steel cable 30 passes around the first steering wheel 29 and enters the limiting block 27 from a set of cable inlets 31. Then, the first steel cable 30 passes around the first load-bearing wheel 32 and moves out from another set of cable inlets 31, increasing the length of the first steel cable 30 extended to the outer end of the mounting base 21. When the second movable shaft 25 rotates, it drives the two sets of second take-up rollers 26 to rotate, so that the second steel cables 36 surrounding the outer ends of the two sets of second take-up rollers 26 are released from the two sets of second cable outlets 39 respectively. Then, the two sets of second steel cables 36 pass around the two sets of steering columns 33 and the second steering wheel 35 respectively and enter the interior of the limiting block 27 from the two sets of cable inlets 31 respectively, increasing the length of the two sets of second steel cables 36 extended to the outer end of the mounting base 21. When the length of the first steel cable 30 and the two sets of second steel cables 36 extended to the outer end of the mounting base 21, the limiting block 27 causes the hook 28 to move downward. The hook 28 moves to the upper end of the electromagnetic adsorption device. Then, the operator turns off the third motor 22 through the remote control device. Then, the operator connects the hook 28 to the hanging ring pre-set at the upper end of the electromagnetic adsorption device. The diameter of the first winding roller 24 is smaller than the diameter of the two sets of second winding rollers 26. When the first steel cable 30 and the two sets of second steel cables 36 are respectively engaged with the first load-bearing wheel 32 and the two sets of second load-bearing wheels 37, the first steel cable 30 and the two sets of second steel cables 36 always maintain tension. After the hook 28 is connected to the pre-set hanging ring at the upper end of the electromagnetic adsorption device, the operator first starts the third motor 22, which drives the first winding roller 24 and the two sets of second winding rollers 26 to rotate. The first winding roller 24 and the two sets of second winding rollers 26 respectively wind up the first steel cable 30 and the two sets of second steel cables 36, pulling the limit block 27 and the hook 28 upward, thereby driving the electromagnetic adsorption device and the steel liner plate upward. After the steel liner plate moves to a certain height, the operator turns off the third motor 22 through the remote control device, and then starts the first motor 6 and the second motor 13 to drive the steel liner plate to move. The first steel cable 30 and the two sets of second steel cables 36 generate tension from the four ends of the limit block 27, thereby improving the stability of the limit block 27 and the hook 28 during the movement, thus improving the stability of the steel liner plate during the movement, avoiding swaying of the steel liner plate during the movement, and improving the safety of the steel liner plate transported by the crane.
