Description

Technical Field

[0001] The utility model belongs to the technical field of prebaked anode production, in particular to a device for preventing carbon anodes from being injured by falling when a clamp-type overhead crane is unloaded from the furnace. Background Art

[0002] During the prebaked anode production process, a clamp-type overhead crane is used to mechanically load and unload the anodes from the furnace, saving significant labor. However, during this process, the clamps must carry nearly 24 tons of carbon blocks from the furnace surface to the unpacking machine, causing vibration and the risk of them falling. This poses a significant safety hazard to personnel, equipment, and the furnace itself. Summary of the Invention

[0003] The utility model aims to address the technical defects of the existing technology and provide a device for preventing carbon anodes from falling out of the furnace by a clamp-type overhead crane, so as to solve the current problem that when a clamp-type overhead crane is used for roasting and taking out the furnace, if the carbon blocks fall, they will cause harm to personnel, equipment and the furnace body.

[0004] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0005] A device for preventing falling injuries when a carbon anode clamp-type overhead crane is unloaded from a furnace comprises a support body, a connecting rod, a clamp, a rectangular frame, an upper hook body, a lower hook body, and a steel wire rope, wherein the upper end of the connecting rod is rotatably connected to the support body, the lower end of the connecting rod is rotatably connected to the clamp, a carbon block is clamped on the clamp, the rectangular frame surrounds the outer periphery of the carbon block, the upper hook body is fixedly connected to the support body, the lower hook body is fixedly connected to the rectangular frame, and a steel wire rope is connected between the upper hook body and the lower hook body.

[0006] Preferably, a steel wire rope and an upper hook and a lower hook at both ends thereof form a group of hanging structures, and the hanging structures are provided with four groups, two of which are located at the front side of the support body, and the other two groups are located at the rear side of the support body.

[0007] Preferably, the lower portion of the clamp is also located within the enclosure of the rectangular frame.

[0008] Preferably, the rectangular frame has a length of 6.8 m, a width of 0.8 m and a height of 0.4 m.

[0009] Preferably, the rectangular frame is formed by welding square tubes, wherein the width of the square tubes is 0.1 m and the wall thickness is 0.01 m.

[0010] When the clamp-type crane is lifting the carbon blocks out of the furnace, the loss of metallurgical coke during the roasting process and the reduction of filling materials between the carbon blocks due to vibration during the lifting process reduce the contact area, causing the carbon blocks to fall, thereby causing damage to personnel, equipment and the furnace body.

[0011] Observations revealed that when charcoal blocks are hoisted, the ground clearance is approximately 30 cm, and the height of this type of charcoal block is 177.5 cm. Based on this, the present invention employs a rectangular frame as the enclosure structure, maintaining its height at approximately 147.5 cm during normal hoisting, effectively limiting damage to surrounding personnel and equipment from falling charcoal blocks.

[0012] When the charcoal block is taken out of the furnace, the clamp is extended out of the furnace chamber, and the four connecting ropes of the utility model are hung, so as to basically control the movement range of the charcoal block when it falls, thereby preventing safety accidents.

[0013] The beneficial effect of the invention is that by controlling the movement range of the carbon blocks when they fall, they can all fall on the safe passage, without causing damage to surrounding workers, temperature control equipment and the furnace body itself, thereby minimizing economic losses.
