Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel production technology, specifically relating to a steel ladle transport track shuttle device. Background Technology
[0002] In a steel production workshop, molten steel heated in a furnace is placed in a ladle. A tracked trolley then transports the ladle along a dedicated track to the casting location. However, due to space limitations, there is only one track leading to the casting location. Therefore, to move the ladle from the ladle transport track to the casting location track, it needs to be merged into the casting location track. But with multiple ladle transport tracks, merging them all at once would result in multiple trolleys simultaneously entering the casting location track, causing interference and collisions. Utility Model Content
[0003] Based on this, this application provides a steel ladle transport track transfer device to solve the technical problem in the prior art where the track trolleys traveling on multiple tracks tend to interfere with each other when multiple tracks are merged into the same track.
[0004] The technical solution to the above-mentioned technical problems in this application is as follows:
[0005] A ladle transport track transfer device, wherein the transport track has one common track, at least two transport tracks, and one casting track, and the end point of the transport track and the start point of the casting track are both located within the coverage area of the common track, including:
[0006] A movable component, the movable component being capable of moving on a common track;
[0007] A connecting component is disposed on the moving component. The moving component can drive the connecting component to move to the end of the transport track and the beginning of the casting track, for transferring the track trolley between the transport track and the casting track.
[0008] Preferably, the transport track includes two parallel first rails, which are laid on the ground and end on one side of the common track.
[0009] Preferably, the common track includes two parallel second rails, and the moving component is capable of moving along the second rails.
[0010] Preferably, the movable component includes a movable frame and a traveling wheel disposed at the lower end of the movable frame, the traveling wheel being able to roll on the common track, and the connecting component being disposed on the movable frame.
[0011] Preferably, the moving component further includes a power unit connected to the walking wheel for driving the walking wheel to rotate.
[0012] Preferably, the connecting component includes a base plate and a mating portion disposed on the base plate, the mating portion being capable of connecting with the end point of the transport track or the starting point of the casting track.
[0013] Preferably, the docking portion includes two parallel third rails, which can connect the end points of the two first rails or the starting point of the cast track.
[0014] Preferably, the docking part further includes an adjustment part, which is capable of adjusting the distance between the two third rails.
[0015] Preferably, the adjusting part includes a limiting strip disposed on the base plate along a direction perpendicular to the third rail, and a telescopic rod.

[0016] Preferably, the casting track includes two parallel fourth rails, the starting points of which are located on one side of the common track.
[0017] Compared with the prior art, this application has at least the following advantages:
[0018] This application provides a ladle transport track transfer device. Utilizing the transport track, a track trolley can transport a ladle between the heating furnace and a shared track. The track trolley can then transport the ladle along the transport track. When it is necessary to transport molten steel to the casting position, a moving component drives a connecting component to move along the shared track to the end of the transport track to complete the connection. The track trolley then travels along the transport track onto the connecting component, at which point the track trolley carrying the ladle moves onto the moving component. The moving component then moves along the shared track to the starting point of the casting track, where the connecting component connects with the casting track. Subsequently, the track trolley can travel from the connecting component onto the casting track and move along the casting track to the casting position. After casting is completed, the operation is reversed, allowing the track trolley to carry the empty ladle back to the heating furnace to collect molten steel. The system can transfer ladles on multiple transport tracks in a sequential manner using a shuttle method, avoiding interference or collisions caused by multiple ladles passing through the casting track. This ensures that the transfer of ladles on multiple transport tracks is carried out in an orderly manner, and the ladles are transferred to the casting track in sequence for casting operations.

[0027] Please refer to Figures 1 to 4 In one specific embodiment of this application,
[0028] A ladle transport track transfer device, wherein the transport track has one common track, at least two transport tracks, and one casting track, and the end point of the transport track and the start point of the casting track are both located within the coverage area of the common track, including:
[0029] A movable component, the movable component being capable of moving on a common track;
[0030] A connecting component is disposed on the moving component. The moving component can drive the connecting component to move to the end of the transport track and the beginning of the casting track, for transferring the track trolley between the transport track and the casting track.
[0031] The shared track, transport track, and cast track can all be railway rails, steel rails, or other devices and facilities used to guide the movement of the track trolley. The moving component can be a traveling vehicle, an AGV, or other devices and facilities capable of moving along the track. The connecting component can be a moving platform, a track, or other devices and facilities capable of docking with the track.
[0032] Using a transport track, a trolley can transport a ladle between the heating furnace and the common track. The trolley can then transport the ladle along the transport track. When it is time to transport the molten steel to the casting position, the moving component drives the connecting component to move along the common track to the end of the transport track to complete the connection. The trolley then travels along the transport track to the connecting component, where it carries the ladle to the moving component. The moving component then moves along the common track to the starting point of the casting track, where the connecting component connects with the casting track. The trolley can then travel from the connecting component to the casting track and move along the casting track to the casting position. After casting is completed, the operation is reversed, allowing the trolley to carry the empty ladle back to the heating furnace to collect the molten steel.
[0033] The above method allows the railcars that transfer steel ladles on multiple transport tracks to complete the transfer sequentially using a ferry method. This avoids interference or collisions caused by multiple railcars passing each other on the casting track, ensuring that the transfer of steel ladles on multiple transport tracks is carried out in an orderly manner, and that the steel ladles are transferred to the casting track in sequence for casting operations.
[0034] In a preferred embodiment: the transport track includes two parallel first rails 201, which are laid on the ground and end at one side of the common track.
[0035] Two first steel rails 201 are laid on the workshop floor. The starting point can be the area next to the heating furnace where molten steel is added to the ladle. The rail trolley can then carry the ladle and move it along the two first steel rails 201. After the molten steel is collected next to the heating furnace, the rail trolley moves along the two first steel rails 201 to the end position to wait. Then, the moving component drives the connecting component to move along the common track to the end of the two first steel rails 201, so that the rail trolley can move the ladle to the connecting component. Then, the moving component drives the rail trolley to swing along the direction of the common track until it is aligned with the starting point of the casting track.
[0036] In a preferred embodiment: the common track includes two parallel second rails 101, and the moving component is capable of moving along the second rails 101.
[0037] When the two second steel rails 101 are laid, their range covers the ends of multiple transport rails and the beginning of the casting rail. When the moving component drives the connecting component along the two second steel rails 101, it can pass through the ends of multiple transport rails and the beginning of the casting rail. This allows the railcar stopped at the end of any transport rail to move onto the connecting component and then transfer the railcar to the beginning of the casting rail. By sharing the moving component across multiple transport rails, the moving component can drive the connecting component to sequentially transfer the railcars stopped on multiple transport rails.
[0038] In a preferred embodiment: the moving component includes a moving frame 401 and a traveling wheel 402 disposed at the lower end of the moving frame 401, the traveling wheel 402 being able to roll on the common track, and the connecting component being disposed on the moving frame 401.
[0039] The mobile frame 401 can move along a common track via the wheels 402. The connecting component is connected to the mobile frame 401 and moves with it, enabling movement between the ends of multiple transport tracks. The mobile frame 401 will drive the connecting component to a position aligned with the end of any transport track, allowing the track trolley parked at the end of the transport track to move onto the connecting component, thus completing the transfer process while the mobile frame 401 is moving.
[0040] In a preferred embodiment, the moving component further includes a power unit 403, which is connected to the walking wheel 402 and is used to drive the walking wheel 402 to rotate.
[0041] The power unit 403 can be a motor, an engine, or other device and facility that can provide rotational driving force to the traveling wheel 402. In other words, the power unit 403 can provide power to the traveling wheel 402, enabling the traveling wheel 402 to roll and move on a common track, thus realizing the automatic movement process of the moving component.
[0042] In a preferred embodiment, the connecting component includes a base plate 501 and a docking portion disposed on the base plate 501, the docking portion being capable of connecting with the end point of the transport track or the starting point of the casting track.
[0043] The base plate 501 is connected to the moving component (the moving frame 401 mentioned above), and the docking part is connected to the base plate 501. When the traveling wheel 402 rolls, the moving frame 401 can drive the base plate 501 to move along the common track, so that the docking part can move to a position aligned with the end point of any transport track, so that the track trolley parked at the end point of the transport track can drive onto the docking part.
[0044] In a preferred embodiment: the casting track includes two parallel fourth rails 301, the starting points of the two fourth rails 301 being located on one side of the common track.
[0045] Two parallel fourth steel rails 301 are laid on the workshop floor, and the spacing is the same as that of the two first steel rails 201. This allows the rail trolley to travel on the two first steel rails 201 and the two parallel fourth steel rails 301. The starting point of the two parallel fourth steel rails 301 is located on one side of the shared track, and the ending point is located at the casting position. This allows the rail trolley to move along the two parallel fourth steel rails 301 to the ending point to pour the molten steel from the ladle into the mold.
[0046] In a preferred embodiment: the docking portion includes two parallel third rails 502, which can connect the end points of the two first rails 201 or the starting point of the cast track.
[0047] The spacing between the two parallel third rails 502 is consistent with the spacing between the two first rails 201 and the two parallel fourth rails 301. Therefore, the trolley can move along the two first rails 201 to the two third rails 502, and then move from the two third rails 502 to the two fourth rails 301.
[0048] In a preferred embodiment, the docking portion further includes an adjustment portion, which is capable of adjusting the spacing between the two third rails 502.
[0049] The adjusting unit can be a gear rack, screw slider, or other device or facility capable of adjusting the spacing between the two third rails 502. It can adjust the spacing of the third rails 502 according to the spacing of the rails in pre-laid or subsequently added transport tracks to meet usage requirements. For example, as production lines and transport routes increase, and the corresponding transport tracks have different spacings due to upgrades or different models, the connecting unit, driven by the adjusting unit, can meet the usage requirements and connect rails with different spacings into the common track's transition range.
[0050] In a preferred embodiment: the adjusting part includes a limiting strip 503 disposed on the base plate 501 along a direction perpendicular to the third rail 502, and a telescopic rod 504. The fixed end of the telescopic rod 504 is connected to one of the third rails 502, and the third rail 502 is fixed to the base plate 501. The movable end of the telescopic rod 504 can drive the other third rail 502 to slide on the limiting strip 503.
[0051] The height of the telescopic rod 504 is lower than the upper surface of the third rail 502, so there will be no interference with the track trolley. When adjusting the distance between the two third rails 502, the movable end of the telescopic rod 504 will drive the other third rail 502 to move along the limit bar 503 when it extends and retracts. Under the restriction of the limit bar 503, there will be no deviation in any direction other than the direction of movement, thus completing the adjustment of the distance between the two third rails 502.
[0052] Specifically, an embodiment of the above process is provided:
[0053] like Figure 1 As shown in the diagram, G represents the railcar carrying the ladle, and L represents the heating furnace. For example, the endpoints of two transport tracks distributed to the left and right are located on one side of a common track, while the starting point of the casting track is located on the other side. In actual production, the railcar on the left transport track can move the ladle to the heating furnace to load molten steel. Then, the railcar moves along the transport track to its endpoint. The moving component then moves the connecting component along the common track to the endpoint of the transport track and aligns it with the connecting component. The moving component then moves the connecting component to the casting track, allowing the railcar to move onto the connecting component. The moving component then aligns the connecting component with the casting track, and the railcar can then transport the molten steel to the casting position. After casting, the railcar returns to the left transport track for a second molten steel loading. The moving component then moves the connecting component to the endpoint of the right transport track, transferring the railcar and ladle from the right transport track, completing the transfer process.
[0054] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
