[0011] The present invention provides a large ring forging hot processing hoisting device. It has the following beneficial effects:

[0012] 1. The large ring forging hot processing hoisting device, through the setting of the heat absorption mechanism, when the clamping mechanism drives the shovel block to move, since the top of the shovel block is an inclined surface, the ring forging will be shoveled up through the inclined surface, so that it is more convenient to grab the ring forging, no staff assistance is required, and it is more convenient. At the same time, the clamping claw is set to an arc shape, which can more firmly grab the ring forging to prevent it from falling off or sliding, thereby causing safety accidents or weakening the processing effect. At the same time, since the heat of the ring forging is very high during processing, the motor drives the stirring plate 1 and the stirring plate 2 inside the heat absorption box to rotate, so as to quickly absorb the heat of the arc-shaped clamping claw, which can break the thermal boundary layer between the hot surface and the coolant, enhance heat convection and heat conduction, thereby accelerating the transfer and dissipation of heat, and at the same time can take away the heat absorbed by the sling in time, reduce the temperature of the sling, thereby reducing the thermal stress and material fatigue caused by the sling working at high temperature for a long time, so that the clamping effect of the arc-shaped clamping claw is better.

[0013] 2. The large ring forging hot processing hoisting device is provided with a heat dissipation mechanism. Whenever the coolant in the heat absorption mechanism is used for a period of time, the cylinder is started to drive the sealing plate to move. The thickness of the sealing plate can block the gap at the bottom of the insulation plate. Therefore, when the sealing plate rises, the coolant in the heat absorption mechanism will flow into the replacement box, and the coolant in the replacement box will be pushed upward by the sealing plate to flow into the heat absorption mechanism. When the cylinder returns, the rotating door can only be opened upward in one direction under the limit of the sealing plate. Therefore, the used coolant will be discharged into the replacement box through the rotating door. This can ensure that the cooling medium always maintains the best state and provides the most effective cooling effect. It can also more effectively absorb the heat on the hanger and the ring forging, thereby reducing the temperature of these components and preventing the degradation of material properties or thermal damage caused by overheating, thereby better clamping the ring forging and avoiding sliding and falling off.

[0014] 3. The large ring forging hot processing hoisting device, through the setting of gear three and U-shaped tube, the motor drives gear three to rotate, gear three drives four gears to rotate simultaneously, and when gear four rotates, it drives the spiral blade in the rotating tube to rotate, thereby accelerating the flow of coolant in the U-shaped tube. At the same time, the refrigerator continuously generates cold air to cool the coolant in the U-shaped tube, so that all the heat in the used coolant can be absorbed, which is convenient for replacing another part of the coolant after use. In this way, a small part of the coolant can be recycled to achieve a better fixture heat absorption effect, while saving resources, better clamping the ring forgings, and avoiding problems in clamping the ring forgings.

[0015] 4. The large ring forging hot processing hoisting device, through the setting of the clamping mechanism, the hydraulic cylinder drives the sliding plate to slide in the sliding groove, and when the sliding plate slides, the L-shaped rod drives it to slide with the sliding plates in three directions, so as to clamp the ring forging from four directions at the same time, so as to ensure that the clamping force on the ring forging in all directions is more uniform. This helps to prevent the ring forging from deformation or distortion during the processing, thereby ensuring the processing accuracy and product quality, and can effectively prevent it from sliding or shifting during the processing.
