[0018] The traverse track is used to transition the traverse trolley to the auxiliary track set up at each workstation of the production line.

[0019] Optionally, in the above-mentioned automatic transfer equipment, the parking track, the traverse track, and the auxiliary track are all at the same horizontal level.

[0020] Optionally, in the above-mentioned automatic transfer equipment, the automatic transfer equipment further includes: a limiting component;

[0034] This application utilizes a traveling trolley, a traversing trolley, and a lifting device. The traveling trolley, carrying the traversing trolley, moves along the main track of the production line to the vicinity of the target workstation and stops. The traversing trolley, carrying the lifting device that holds the material (such as the ingot mold base plate), leaves the parking position at the top of the traveling trolley and moves along the secondary track between the main track and the target workstation to the target workstation. The lifting device then lowers to drop the ingot mold base plate. After unloading, the traversing trolley, carrying the lifting device, moves back along the secondary track to the parking position at the top of the traveling trolley. In this way, the traveling trolley, the traversing trolley, and the lifting device work together to automatically transfer the ingot mold base plate to the position designated by the casting process operator (i.e., the target workstation). This achieves fully automated transfer of the ingot mold base plate, replacing the tedious process of manual transfer and effectively improving the efficiency of the base plate in the mold-sanding process of the casting production line in the smelting industry.

[0041] Please see Figure 1-3 The present invention provides the following technical solution: an automatic transfer device. The automatic transfer device includes: a traveling trolley 1, a transverse trolley 2, and a lifting device 3.

[0042] The traveling trolley 1 moves along the main track of the (molding) production line. The traverse trolley 2 is connected to the traveling trolley 1 via a cable chain 9. The traverse trolley 2 moves back and forth along the width of the traveling trolley 1 (also called traverse movement), allowing it to move back and forth between the target workstation on the production line and the parking position at the top of the traveling trolley 1. The traverse trolley 2 is hydraulically driven, with a hydraulic motor mounted on it, and control lines and oil pipes mounted on the cable chain 9. The cable chain 9 moves with the traverse trolley 2. A lifting device 3 is mounted on top of the traverse trolley 2. The lifting device 3 generates a certain thrust, which is used to support and unload materials, or in other words, the lifting device 3 controls the lifting and lowering process of the materials. In this article, the material used is a steel ingot mold base plate. During use, the traveling trolley 1 moves along the main track of the production line with the traverse trolley 2 to the vicinity of the target station. When the traveling trolley 1 stops moving, the traverse trolley 2, carrying the lifting device 3 that carries the steel ingot mold base plate, leaves the parking position at the top of the traveling trolley 1 and moves along the secondary track between the main track and the target station to the target station. When the traverse trolley 2 stops moving, the lifting device 3 descends and drops the steel ingot mold base plate. After unloading, the traverse trolley 2, carrying the lifting device 3, moves back along the secondary track to the parking position at the top of the traveling trolley 1, and the operation process ends. In this application, the traveling trolley 1, the lateral trolley 2, and the lifting device 3 work together to automatically transfer the steel ingot mold base plate to the position designated by the casting process operator (i.e., the workstation mentioned in this article). This achieves fully automated transfer of the steel ingot mold base plate, replacing the tedious process of manual transfer. It solves the problem that in the prior art, before the base plate is laid in the casting process, it is often necessary to manually direct cranes and other lifting equipment to transfer it. The transfer process involves multiple operations, and each step requires manual operation, which is time-consuming and labor-intensive. This effectively improves the efficiency of the base plate in the casting production line of the smelting industry.

[0043] It should be noted that each workstation has a secondary track with a horizontal height higher than the main track on the side closest to the main track, allowing the traverse trolley to reach that workstation. Furthermore, when the entire system is not in operation, or after the steel ingot mold base plate has been delivered to the target workstation, the traverse trolley 2 will automatically return to its parking position above the traveling trolley 1 to ensure the smooth execution of the next step.

[0044] As a preferred embodiment of the above embodiment, in this embodiment, the automatic transfer device further includes: a coding ruler and a code reader 6. Specifically, the coding ruler (not shown in the figure) is a high-precision measuring tool that uses digital signals for measurement. Preferably, the length of the coding ruler is the same as the length of the main track. The code reader 6 is installed on the traveling trolley 1 (such as the trolley body) and is connected to the coding ruler. The control terminal of the traveling trolley 1 is connected to the code reader 6, which is used to accurately locate the position of the traveling trolley 1 during its movement. In use, the entire coding ruler is placed near the track (i.e., the main track) where the traveling trolley 1 is traveling. The code reader 6 can read the data (i.e., readings) provided by the coding ruler that follows the movement of the traveling trolley 1, and calculate and determine the distance traveled by the traveling trolley 1, how much it has traveled, and where it has reached. When the control terminal of the traveling trolley 1 calculates through the code reader 6 that the traveling trolley 1 has traveled the distance along the main track and reached the target workstation, the traveling trolley 1 stops moving, thus achieving accurate positioning of the traveling trolley 1 during its movement.

[0045] Reference Figure 2 and Figure 3 As shown, the parking space has a parking track (not shown) along the width of the traveling trolley 1 for parking the traversing trolley 2. The length of the parking track is equal to the width of the traveling trolley 1. A traversing track 5 is provided on one side of the parking track on the traveling trolley 1. The traversing track 5 is used to transition the traversing trolley 2 to the auxiliary track provided at each workstation on the production line. After leaving the parking track, the traversing trolley 2 can move along the traversing track 5 to reach the auxiliary track at the target workstation (which can be on the left or right side of the main track, consistent with the site layout). Simultaneously, the traversing trolley 2 can also return to the parking track at the parking space on the traveling trolley 1 along the traversing track 5. It should be noted that the number of auxiliary tracks is the same as the number of workstations on the production line. All workstations on the same side of the main track are located on the same straight line, and all auxiliary tracks on the same side of the main track are located on the same straight line (which can also be understood as end alignment). Preferably, the parking track, the traverse track 5, and the auxiliary track are all at the same horizontal level, which facilitates the traverse trolley 2 to move to the target workstation or smoothly return to the parking position from the target workstation.

[0046] To ensure safety and prevent personal injury during transport, the automated transfer equipment also includes a limit switch assembly. This assembly is located between the traverse trolley 2 and the workstation on the production line, stopping the traverse trolley 2 at a designated position. Specifically, the limit switch assembly includes a first limit switch and a second limit switch. The first limit switch is installed at the workstation on the production line and is connected to the control unit of the traverse trolley 2. When the first limit switch detects that the traverse trolley 2 has reached the target workstation, it triggers an emergency stop signal. The control unit of the traverse trolley 2 receives and executes the emergency stop signal, stopping its movement. Subsequently, the lifting device 3 unloads the material. First limit switches can be installed at multiple (or even each) workstations on the production line as needed. The second limit switch is installed at the parking space of the traveling trolley 1. The second limit switch is connected to the control terminal of the traversing trolley 2. The second limit switch is used to detect whether the traversing trolley 2 has returned to the parking space. When the second limit switch detects that the traversing trolley 2 has returned to the parking space, the second limit switch triggers an emergency stop signal. The control terminal of the traversing trolley 2 receives and executes the emergency stop signal to stop moving. At this time, the traveling trolley 1 will perform the next operation.

[0047] Reference Figure 1 As shown, the automated transfer equipment also includes an electrical control cabinet 8. The electrical control cabinet 8 is connected to the control terminals of the traveling trolley 1, the traversing trolley 2, and the lifting device 3, respectively. Thus, the actions of the traveling trolley 1, the traversing trolley 2, and the lifting device 3 can be controlled through the electrical control cabinet 8. This design is safe and reliable; no manual intervention is required during the transfer of the steel ingot mold base plate, reducing the safety hazards caused by lifting equipment hoisting the steel ingot mold base plate.

[0048] As an embodiment of the specific structure of the aforementioned lifting device 3, in this embodiment, the lifting device 3 includes: lifting cylinders. Four lifting cylinders are distributed at the four corners of the transverse trolley 2 (southeast, northeast, southwest, and northwest), and the four lifting cylinders cooperate to hold the lifted base plate in a certain position. When the transverse trolley 2 reaches the target workstation, the four lifting cylinders simultaneously descend to lower the steel ingot mold base plate.

[0049] To ensure the normal operation of the automated transfer equipment, it also includes a sliding contact line and a hydraulic station. The sliding contact line supplies power to the electrical equipment on the automated transfer equipment, thus ensuring the stable operation of all control systems within the entire system. The hydraulic station supplies power to the drive wheels of the traveling trolley 1 and the traversing trolley 2. For ease of distinction, we will refer to the drive wheels on the traveling trolley 1 as trolley drive wheels 4, and the drive wheels on the traversing trolley 2 as trolley drive wheels 7. It should be noted that all hydraulic actions in the entire system are supplied through the hydraulic station, which is located on the automated transfer equipment.

[0050] Taking the transport of steel ingot mold base plates as an example, the working process of the automatic transfer equipment is described below:

[0051] The traveling trolley 1 moves as a whole by being powered by the trolley drive wheels 4. The distance traveled by the traveling trolley 1 on the main track, its distance traveled, and its location are all calculated and precisely located by the code reader 6. The traveling trolley 1 stops near the target workstation. The traverse trolley 2 moves by being powered by the trolley drive wheels 7. The traverse trolley 2 performs a traverse operation (i.e., carrying the steel ingot mold base plate away from the parking position above the traveling trolley 1 and entering the secondary track leading to the target workstation via the traverse track 5). Each workstation on the production line has a first limit switch. When the traverse trolley 2 reaches the required transport (i.e., the target) workstation, the first limit switch at this workstation is triggered, and the traverse trolley 2 stops moving. At this time, the four lifting cylinders of the lifting device 3 rise synchronously to lift the steel ingot mold base plate. After unloading, the traverse trolley 2 performs a traverse operation again (i.e., moving again via the traverse track 5 until it returns to the parking position above the traveling trolley 1). The main trolley 1 has a second limit switch above it to detect whether the traverse trolley 2 has returned to its original position (the parking track). When the second limit switch is triggered, the traverse trolley 2 will stop moving. At this time, the main trolley 1 will perform the next operation along the main track, that is, it will move along the main track to the next process, the mold placement station, carrying the traverse trolley 2 and the steel ingot mold base plate that has just been transported from the work station and has been laid out. When the main trolley 1 reaches the work station after the distance is calculated by the code reader 6, the main trolley 1 will stop moving. Then the traverse trolley 2 will start moving along the steel ingot mold base plate to the mold placement station. After reaching the designated position of the mold placement station, the four lifting cylinders of the lifting device 3 will descend synchronously to lower the steel ingot mold base plate. Then the traverse trolley 2 will return to the parking position above the main trolley 1 (i.e., the parking track) via the traverse track 5. The entire operation is completed and the whole set of equipment will wait for the next command. This cycle will be repeated to realize the automation and unmanned operation of the whole process.

[0052] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
