[0002] In the steelmaking process, the steelmaking electric arc furnace and the ladle refining furnace are core equipment, and the ladle needs to be transported between the two by the ladle. In order to achieve efficient ladle transportation, the existing steelmaking electric arc furnace and the ladle refining furnace are usually designed to be on the same horizontal line so that the ladle can be smoothly moved horizontally between the two. However, due to the geographical location and space limitations of the smelter, the steelmaking electric arc furnace and the ladle refining furnace are often not completely kept on the same horizontal line, which will cause inconvenience to the transportation path of the ladle and affect the transportation efficiency; Most of the existing ladle conveying devices rely on traditional rail systems, which cannot flexibly adapt to the transportation challenges brought about by the changes in the relative positions of the steelmaking arc furnace and the ladle refining furnace. This fixed rail system often requires a large area of ​​space, and its adjustment process is cumbersome, and it cannot make full use of the limited plant space, resulting in inconvenience in the transportation process, increased equipment wear and maintenance costs, and affecting the overall efficiency of the production line. At the same time, the existing system has poor adaptability to different ladle sizes and loads, and cannot automatically adjust the transportation path according to different loads. When faced with changes in the size of the ladle, manual intervention is often required, resulting in reduced production efficiency and complicated equipment management. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-8 The present invention provides a technical solution for a ladle conveying device, and its detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process, and the specific operations are as follows.

[0020] A ladle conveying device comprises: a base plate 1, a turntable 2, a transmission device 3, a hydraulic power unit 4, a hydraulic motor 51, a liquid storage tank 6, a worm 7, and a worm wheel 8.

[0021] A circular through hole 12 is provided at the center of the top surface of the base plate 1. The base plate 1 is the basic supporting structure of the entire ladle conveying device. The design of the through hole 12 facilitates the rotation of the turntable 2, ensuring the stability and flexibility of the turntable 2. The base plate 1 is fixedly laid on the ground, and it is ensured that the top surface of the base plate 1 is at the same level as the original basic platform 111. At the same time, a deep pit is pre-dug directly below the through hole 12 to ensure the installation of the bottom surface of the turntable 2 and the components below. The turntable 2 is rotatably arranged in the through hole 12. The turntable 2 is the core component of the device. The track on the turntable 2 is connected to the track of different angles on the base plate 1 through rotation. The rotation angle of the turntable 2 can be adjusted. In order to adjust according to needs, the conveying path can be flexibly changed. The transmission device 3 is arranged on one side of the top surface of the turntable 2. Through the transmission device 3, the external power source (such as an electric motor or a hydraulic system) is converted into the rotational power of the turntable 2, so as to realize the accurate positioning and operation of the turntable 2. The two hydraulic power units 4 are arranged at the bottom edge of the turntable 2. The two hydraulic power units 4 are symmetrically distributed on the bottom surface of the turntable 2 to ensure that the force of the turntable 2 is uniform, thereby effectively reducing the tilting phenomenon of the turntable 2 caused by uneven force. This design can greatly reduce the wear of the turntable 2 during operation, improve the operation stability and use of the system The service life of the turntable 2 is improved, and long-term failures or repair requirements caused by uneven force distribution are avoided, and maintenance costs are reduced. The two hydraulic power units 4 are respectively connected to the transmission device 3 by mechanical transmission. The two hydraulic power units 4 provide the hydraulic power required for the rotation of the turntable 2. The hydraulic motor 51 is connected to the two hydraulic power units 4 through a hydraulic pipeline. The hydraulic motor 51 is the driving source for realizing the movement of the turntable 2. Its operation depends on the pressure provided by the hydraulic system. The hydraulic pipeline transmits the hydraulic power from the accumulator and the hydraulic pump 41 to the hydraulic motor 51, and the turntable 2 is driven by the rotation of the motor to accurately control the movement of the turntable 2. The liquid tank 6 is located between the two hydraulic power units 4 and the hydraulic motor 51, and are connected in turn through hydraulic pipelines. The liquid tank 6 is used to store hydraulic oil and maintain the hydraulic pressure in the system stable. The capacity and design of the liquid tank 6 directly affect the stability and efficiency of the hydraulic system, ensuring that there is no pressure fluctuation in the hydraulic system during long-term operation. The worm 7 is arranged at the output end of the hydraulic motor 51. The worm 7, as a key component of mechanical transmission, converts the rotational power of the hydraulic motor 51 into a low-speed and high-torque output. The worm wheel 8 is rotatably arranged on the bottom surface of the turntable 2, and the worm wheel 8 and the worm 7 are meshed with each other. The worm wheel 8 and the base plate 1 are in relative stillness.

[0022] The hydraulic power unit 4 includes a hydraulic pump 41 and a hydraulic accumulator 42 .

[0023] The hydraulic pump 41 is connected to the liquid storage tank 6 by a hydraulic pipeline. The hydraulic pump 41 provides the required pressure by extracting hydraulic oil from the liquid storage tank 6 to ensure the hydraulic power output. The hydraulic pump 41 includes but is not limited to the use of a gear pump, a plunger pump, etc. The hydraulic accumulator 42 is located between the hydraulic pump 41 and the hydraulic motor 51, and is connected in turn through hydraulic pipelines. The hydraulic accumulator 42 is used to store and release hydraulic energy. The hydraulic accumulator 42 is equipped with a pressure holding valve. When the hydraulic pump 41 stops working, the hydraulic oil in the system is maintained at a set pressure through the pressure holding valve. The hydraulic accumulator 42 does not release the pressure instantaneously, but releases the stored pressure stably through the setting of the valve to provide continuous pressure for the system. This process is a technology well known to those skilled in the art, and the pressure holding valve, etc. are not shown in the figure.

[0024] The transmission device 3 includes a base 31 , a first gear 32 , a second gear 33 and two transmission belts 34 .

The rotation axes of the first gear 32 and the second gear 33 are parallel to each other and perpendicular to the extension direction of the track on the turntable 2. The two transmission belts 34 are respectively connected to the rotating shaft of the first gear 32 and the rotating shaft of the second gear 33, and are connected to the driving ends of the corresponding two hydraulic pumps 41. The rotation of the transmission belt 34 drives the rotation of the first gear 32 and the second gear 33, so as to further drive the operation of the two hydraulic pumps 41. The operation of the two hydraulic pumps 41 is driven by driving the rotation of the first gear 32 and the second gear 33 respectively, wherein the first gear 32 and the second gear 33 are staggered.

[0026] A three-part track is arranged on the top surface of the base plate 1, and a corresponding track is arranged on the top surface of the turntable 2, and the turntable 2 is located at the bifurcation point of the three-part track.

[0040] Working principle: according to different capacities, choose ladles with different outer diameters. When the outer diameter of the ladle is smaller than the inner diameter of the second tray 113, place the ladle in the center of the first tray 112. At this time, the first tray 112 is pressed down, and the second tray 113 is stationary. At this time, the first pressure rod 114 and the first rack 116 move down synchronously to control the transport vehicle 11 to move to the position of the turntable 2. During the movement of the transport vehicle 11, the first rack 116 meshes with the first gear 32, and the first gear 32 rotates. The corresponding hydraulic pump 41 rotates synchronously, and the hydraulic oil is pressure-transported by the liquid storage tank 6 to the hydraulic accumulator 42 for storage. When the transport vehicle 11 is completely moved to the turntable 2, the first gear 32 stops rotating. At this time, the control The control solenoid valve 52 is opened, and the pressure hydraulic oil will drive the hydraulic motor 51 to operate, thereby driving the worm 7 to rotate. With the cooperation of the worm wheel 8 and the worm 7, the turntable 2 rotates to the corresponding angle N1, and the track on the turntable 2 docks with the track on the base plate 1. At this time, the transport vehicle 11 can be controlled to continue to move forward to the required area, and the solenoid valve 52 is closed. After the operation is completed, the transport vehicle 11 is controlled to move backward to the turntable 2, and the valve in the first hydraulic reversing device 9 is adjusted. In the process of the transport vehicle 11 moving backward to the turntable 2, the hydraulic pump 41 corresponding to the first gear 32 is driven to rotate in the opposite direction, and the turntable 2 is controlled to rotate in the opposite direction to the initial position, so that the transport vehicle 11 carrying the ladle can be controlled to receive molten steel again; When the outer diameter of the ladle is larger than the inner diameter of the second tray 113, the ladle is centered on the center of the first tray 112. At this time, the first tray 112 and the second tray 113 are pressed down at the same time, the first pressure rod 114 and the second pressure rod 115 move down synchronously, and the first rack 116 and the second rack 117 move down synchronously to control the transport vehicle 11 to move to the position of the turntable 2. During the movement of the transport vehicle 11, the first rack 116 meshes with the first gear 32, and the second rack 117 meshes with the second gear 33. The two hydraulic pumps 41 are both in working condition. When the transport vehicle 11 is completely moved to the turntable 2, the solenoid valve 52 is opened, the turntable 2 rotates to the corresponding angle N2, and the track on the turntable 2 is aligned with the track on the base plate 1. Docking, at this time, control the transport vehicle 11 to continue to move forward to the required area, close the solenoid valve 152, and after the operation is completed, control the transport vehicle 11 to move backward to the turntable 2, and adjust the valves in the first hydraulic reversing device 9 and the second hydraulic reversing device 10. In the process of the transport vehicle 11 moving backward to the turntable 2, the hydraulic pump 41 corresponding to the first gear 32 is driven to rotate in the opposite direction, and the turntable 2 is controlled to rotate in the opposite direction to the initial position, and the transport vehicle 11 can be controlled to carry the ladle to receive the molten steel again. If there is no need to adjust the travel angle of the transport vehicle 11, the first rack 116 and the second rack 117 can be removed, and the hydraulic pump 41 will not be driven during the movement of the transport vehicle 11, so that the turntable 2 is in a stationary state. When the outer diameter of the ladle is smaller than the inner diameter of the second tray 113, one hydraulic pump 41 is in operation; when the outer diameter of the ladle is larger than the inner diameter of the second tray 113, two hydraulic pumps 41 are in operation; therefore, the rotation angle N1 of the turntable 2 is smaller than N2, and the travel path can be automatically adjusted according to different loads, thereby achieving precise control of the ladle and improving the diversity of the device.
