[0002] The calcium carbide furnace is the main equipment for producing calcium carbide. The high temperature generated by the electric arc in the calcium carbide furnace causes the charge to melt and react to generate calcium carbide. In the cold pack area of ​​the calcium carbide furnace, the double-clamp clamp of the overhead crane is usually used to hoist the calcium carbide pot and flip the pot, so as to realize the demoulding of the pot. During the use of the double-clamp clamp, due to the high temperature of the calcium carbide lump, the double-clamp clamp is deformed and the weld cracks due to the heat and load-bearing factors. If it is not discovered in time, the double-clamp clamp will be damaged during the process of hoisting the calcium carbide pot, which is easy to damage the furnace unloading equipment. The double-clamp clamp is frequently worn and has a short service life. In addition, manual auxiliary hooks are required when hoisting the calcium carbide pot, which has low work efficiency and high operation risks. Utility Model Content

When the flip disk 3 is in the initial position, the flipping slot 6 is larger at the top and smaller at the bottom, so that the clamping column 8 of the calcium carbide pot 7 can be placed in the flipping slot 6; a driving member is arranged on the mounting beam 1, and the driving member is used to drive any flip disk 3 to rotate; a load-bearing limiting part is arranged on the two vertical beams 2, and the load-bearing limiting part bears and limits the clamping column 8 of the calcium carbide pot 7; combined with Figure 4, a clamping column 8 is arranged on the two opposite outer walls of the calcium carbide pot 7, and the ends of the two clamping columns 8 are arranged to be V-shaped clamping parts 9, and the V-shaped clamping parts 9 are adapted to the shape of the flipping slot 6 of the flipping plate 3; when using the pot-turning device, fixed pulleys are first arranged at the four corners of the mounting beam 1, and then the four fixed pulleys are connected to the steel wire rope of the overhead crane inside the factory building, and the overhead crane drives the pot-turning device to move, so that the two flipping plates 3 move to the bottom of the clamping columns 8 on the corresponding sides of the calcium carbide pot 7, and then the overhead crane drives the pot-turning device to rise, so that the clamping columns 8 on both sides of the calcium carbide pot 7 are located at the opposite sides. It should be flipped in the slot 6, so as to quickly and conveniently grab the calcium carbide pot 7. At this time, continuing to lift can lift the calcium carbide pot 7, and then the flip plate 3 is driven to rotate through the driving part. The flip plate 3 drives one side of the calcium carbide pot 7 to rotate through the flip slot 6. Since the clamping column 8 on the other side of the calcium carbide pot 7 is also located in the corresponding flipping slot 6, the calcium carbide pot 7 can be flipped with the rotation of the two flipping plates 3. When the calcium carbide pot 7 is hoisted for flipping, the clamping column 8 of the calcium carbide pot 7 is limited by the load-bearing limit part to bear the load, thereby preventing the calcium carbide pot 7 from escaping from the flipping slot 6 of the flipping plate 3. The shape of the flip slot 6 matches the V-shaped clamping part 9 at the end of the clamping column 8 of the calcium carbide pot 7. On the one hand, it is convenient to quickly put the clamping column 8 of the calcium carbide pot 7 into the flip slot 6, thereby improving the efficiency of lifting the calcium carbide pot 7. On the other hand, due to its special shape, the flip slot 6 can share the weight of the calcium carbide pot 7 and the calcium carbide mass inside it together with the load-bearing limit part, which can reduce the extrusion force caused by the clamping column 8 of the calcium carbide pot 7 on the load-bearing limit part, thereby reducing the wear between the clamping column 8 of the calcium carbide pot 7 and the load-bearing limit part.
