[0002] The steel ingot mold is a bulk ingot casting equipment that is essential for the steel mill's mold casting production and is used in turnover. It is heavy and requires a special lifting mechanism to move it during transportation.
[0003] The Chinese utility model patent with application number 202121057273.1 discloses a lifting mechanism for rotating ingot molds. By arranging a number of automatically retractable sleeves outside the sling, the shaking of the sling is limited, ensuring the stability during transportation. However, if an accidental collision occurs during transportation, the shear force acting on the sleeve can easily cause the sleeve to deform, and eventually it cannot be retracted and extended, affecting the lifting. In addition, when transporting the ingot mold, it is usually necessary to complete the rotation from upright to horizontal. Currently, an inclined bracket is usually required to assist the steering, which is difficult to operate and prone to overturning, posing a safety hazard. Utility Model Content

[0026] See also Figure 1-5 , the utility model provides the following technical solutions:
[0027] A lifting mechanism for rotating ingot molds comprises an ingot mold 1 and a hanger bracket 2. A lower hanging ear 12 and two symmetrically arranged upper hanging ears 11 are arranged on the side wall of the ingot mold 1. A hanger 3 is installed on the hanger bracket 2. Two ropes 34 of the hanger 3 pass through the hanger bracket 2 downward and are hooked with the two upper hanging ears 11 accordingly. The hanger 3 can lift the ingot mold 1. A traction device 4 is installed on the hanger bracket 2. The output end of the traction device 4 is connected with the lower hanging ear 12. The traction device 4 can drive the ingot mold 1 to flip over a certain angle. At this time, the ingot mold 1 is placed on the bottom surface and the hanger 3 is gradually loosened. The ingot mold 1 can be flipped and placed horizontally on the ground. A plurality of protective devices 5 are symmetrically installed on the hanger bracket 2. When the ingot mold 1 shakes, the top end is squeezed against the protective device 5. The protective device 5 acts as a limiter to limit the shaking of the ingot mold 1.
[0028] The traction device 4 includes a motor 41, which is installed on the hanger bracket 2. A bobbin 42 is connected to the output shaft of the motor 41. The bobbin 42 is rotatably connected to the hanger bracket 2. A rope 43 is wound around the bobbin 42. The lower lifting ear 12 is hooked on the rope 43. When the motor 41 is in motion, the ingot mold 1 is tilted by contracting the rope 43.
[0029] The protective device 5 includes a motor 3 51, which is installed on the hanger bracket 2. An extension component 52 is connected to the output shaft of the motor 3 51. The extension component 52 passes through the hanger bracket 2 and is connected to a limit plate 54. The limit plate 54 can be in contact with the top surface of the ingot mold 1. The motor 3 51 controls the lifting and lowering of the limit plate 54 through the extension component 52, so that it is close to the top of the ingot mold 1 to reduce the shaking of the ingot mold 1; a plurality of limit components 53 are arranged between the limit plate 54 and the hanger bracket 2, and the limit components 53 prevent the limit plate 54 from rotating, so that the extension component 52 can only move in the vertical direction; a plurality of ball bearings 55 are installed on the limit plate 54 so as to rotate evenly toward one side of the ingot mold 1. The ball bearings 55 are rubber balls. When the ingot mold 1 squeezes the limit plate 54, the ball bearings 55 rotate and deform, thereby transferring and dissipating part of the impact force, and reducing the shear force on the extension component 52 and the limit component 53.
[0030] The extension component 52 includes a threaded sleeve 521, one end of which is connected to the output shaft of the motor 3 51, the threaded sleeve 521 extends to one side of the ingot mold 1 and is rotatably connected to the hanger bracket 2, the threaded sleeve 521 is internally threadedly connected to the threaded sleeve 2 522, the threaded sleeve 2 522 is internally threadedly connected to the screw 523, the screw 523 extends from the end of the threaded sleeve 2 522 away from the motor 3 51 and is connected to the limit plate 54, the tops of the threaded sleeve 2 522 and the screw 523 are both provided with non-threaded sections, when the threaded sleeve 2 522 and the screw 523 move to the non-threaded section, they can no longer be pushed, which can prevent the threaded sleeve 2 522 and the screw 523 from escaping from the extension component 52.
[0031] The limiting assembly 53 includes a sliding sleeve 531, a sliding sleeve 532 is slidably connected inside the sliding sleeve 531, and a sliding rod 533 is slidably connected inside the sliding sleeve 532. The bottom ends of the sliding sleeve 531 and the sliding sleeve 532 are both provided with limiting positions. When the extending assembly 52 pushes the limiting plate 54 to move downward, the sleeve of the limiting assembly 53 slides automatically to maintain the connection between the sling bracket 2 and the limiting plate 54.
[0032] The hoist bracket 2 includes a support plate 21, and sliders 22 are fixed on both sides of the support plate 21. The sliders 22 can be connected to external moving tracks to drive the overall movement of the hoisting mechanism to complete the transportation.
[0033] The sling 3 includes a motor 31, an output shaft of the motor 31 is connected to a driving bevel gear 311, a plurality of mounting blocks 23 are symmetrically fixed on the support plate 21, two transmission shafts 32 are rotatably connected to the plurality of mounting blocks 23, both transmission shafts 32 are connected to driven bevel gears 321, both driven bevel gears 321 are meshed with the driving bevel gear 311, one end of the transmission shaft 32 away from the motor 31 is connected to a bobbin 33, a rope 34 is wound around the bobbin 33, and the rotation of the motor 31 can drive the corresponding rope 34 to rise and fall through the bobbin 33 on both sides.
[0034] Specifically, when hoisting the steel ingot mold 1, the motor 3 51 of the protective device 5 drives the threaded sleeve 1 521 to rotate, while the limiting plate 54 and the screw 523 cannot rotate under the action of the limiting assembly 4 and can only move up and down, so that the threaded sleeve 1 521 pushes the threaded sleeve 2 522 or the screw 523 to move up and down until the limiting plate 54 contacts the top of the steel ingot mold 1, which plays a limiting role. A plurality of protective devices 5 are symmetrically arranged around the steel ingot mold 1, thereby limiting the shaking of the steel ingot mold 1 and improving the safety of the hoisting process of the steel ingot mold 1.
[0035] The limit plate 54 is connected to the support plate 21 through the extension component 525 and a plurality of limit components 53, which enhances the strength of the connection. The limit plate 54 contacts the steel ingot mold 1 through a plurality of rubber balls 55. The impact force of the shaking steel ingot mold 1 on the limit plate 54 is partially buffered and dissipated through the rotation and deformation of the balls 55, which reduces the shear force acting on the extension component 52 and the limit component 53, making the protective device 5 less prone to damage and extending its service life.
[0036] A traction device 4 is additionally provided on the hanger bracket 2, and a lower lifting ear 12 is provided at the lower end of the ingot mold 1. One end of a rope 43 of the traction device 4 can be hooked with the lower lifting ear 12, and the other end is wound around the bobbin 42. The retraction and extension of the rope 43 is controlled by the motor 41. When the ingot mold 1 needs to be flipped over, the protective device 5 is retracted, and then the rope 43 is retracted to control the ingot mold 1 to tilt, and then the ingot mold 1 can be slowly laid flat. The operation is convenient and the safety is high.
