Description

Technical Field

[0001] The invention relates to the technical field of molten iron ladle hoisting, in particular to a crane used for molten iron ladle hoisting. Background Art

[0002] The iron ladle is a casting equipment used for casting operations in the foundry workshop. It receives molten iron in front of the furnace and then transports it to the mold for pouring by a crane. The iron ladle is a commonly used insulation material in industrial production. It is mainly used to keep the metal in liquid state to prevent the metal from solidifying prematurely and forming inclusions. The iron ladle has certain fire resistance and heat preservation properties, which can effectively protect the molten iron and slag, so that the ironmaking and casting processes can proceed smoothly. In the foundry industry in daily life, iron ladles are often used for product pouring. The ladle is used for pouring operations in the foundry workshop. After receiving the molten iron in front of the furnace, it is transported to the casting mold by a crane for pouring. The transportation and lifting of the ladle are very important. The lifting device of the ladle usually consists of a hook, a locking device, a lifting ring, etc. The hook is mainly used to firmly fix the top of the ladle so that it can be lifted by a crane. The locking device is used to fix the side of the ladle to prevent the ladle from detaching from the lifting device due to tilting and causing an accident. The lifting ring is an important chain connecting the ladle and the hook, and its stability and reliability must be guaranteed.

[0003] When the existing ladle hoisting crane is in use, such as application number CN202122612242.4, it relates to the field of ladle hoisting technology, and in particular to a new ladle hoisting equipment, which solves the problem that the existing technology is carried out by a large workshop beam crane. This traditional hoisting method can only be used in large factories, but it will not be able to meet the requirements when it is carried out in small factories or outdoors, which leads to the limitation of ladle hoisting. A new ladle hoisting equipment includes a frame, a top plate is fixedly connected to the upper inner part of the frame, and the bottom of the top plate is provided with a bottom frame slidably connected to the inner wall of the frame, and the inner side of the bottom frame is rotatably connected to the ladle. The method proposed in the utility model can not only lift and move the molten iron ladle through the winding rod and the sling, but also adjust the height during the pouring of the molten iron ladle, and use the fan to improve the comfort of the workers, which is convenient for the use of the molten iron ladle in a small factory and outdoors, and is convenient, efficient and simple to operate; however, in the above technology, when precise pouring is required, the equipment needs to be moved and operated as a whole, which is cumbersome and dangerous for the user. For this reason, we propose a crane used for lifting molten iron ladle to solve the above problem. Summary of the invention

[0004] In view of the above problems, the present invention proposes a hoisting crane for molten iron ladle, which mainly utilizes the hoisting stabilizing mechanism to hoist the molten iron ladle structure when the various components of the equipment are running, and the output transmission of the reduction gear box and the reduction motor can adjust the rotating cabin under the bolt shaft seat to a suitable target location, so that the side frame and the electric articulated seat cooperate with the transmission mechanical arm and the mechanical claw to pull the ladle shell and the rear ring.

When the driven gear 307 rotates to a suitable angle, the hydraulic cylinder 304 is started to output power to drive the output end to telescope and allow the brake plug 3 05 brake driven gear 307 for positioning, when driven gear 307 is rotating, the rotation of rope drum 308 drives steel cable 3011 to wind, so that steel cable 3011 cooperates with positioning rod 309 to lift, so that steel cable 3011 drives hoisting seat 3012 to adjust hoisting stabilizing mechanism 4 of hoisting molten iron ladle structure 5 to a suitable height, when translation operation is required, drive motor 204 output power is used to drive output end to operate, so that drive motor 204 output power can drive first gear set 205 inside gear box 203 to operate, so that the operation of first gear set 205 can drive second gear set 206 to mesh transmission operation, so that the operation of second gear set 206 The first support wheel 201 at the output end of the gear box 203 is driven to drive the bolt foot seat 207 and the limit bracket 208 to the translation position. When the second working beam 209 runs to a suitable translation position, the drive box group 2012 outside the second car plate 2011 outputs power to drive the output end to run, so that the output power of the drive box group 2012 can drive the second support wheel 2010 to run, and the operation of the second support wheel 2010 drives the second car plate 2011 to drive the lifting transmission component 3 to drive the equipment to a suitable casting position. When the angle needs to be adjusted, the output power of the reduction motor 404 is used to drive the output end to run, so that the output power of the reduction motor 404 can drive the reduction box 403 to perform transmission operation.When the reduction gear box 403 is in transmission operation, the rotating chamber 405 below the bolt shaft seat 402 is adjusted to a suitable angle position. When pouring is required, the electric articulated seat 4018 below one end of the side frame 4017 is used to output power to drive the output end to operate, so that the electric articulated seat 4018 drives the transmission mechanical arm 4019 to output power to drive the mechanical claw hand 4020 to pull the rear ring 504, and after pulling, the carrying round rod 501, the bearing base plate 502, and the water shell 503 cooperate with the arc sleeve 40 14 outputs the molten iron to the casting mold through the output nozzle 505. When unloading is required, the mechanical claw 4020 is used to detach from the molten iron ladle structure 5, and the expansion and contraction motor 406 is used to output power to drive the bevel gear set 407 at the output end to operate, so that the limit rod 409, the threaded strip 4010, and the threaded cylinder 4011 are spirally adjusted, so that the angle arm 4013, the arc-shaped plug sleeve 4014, the angle base 4015, and the hydraulic telescopic rod 4016 are expanded and contracted and then detached from the molten iron ladle structure 5 to achieve the effect of unloading.
