Description

Technical Field

[0001] This invention relates to a collaborative calcium carbide tapping and transfer system and method using an RGV trolley and a mobile platform, belonging to the technical field of calcium carbide production equipment. Background Technology

[0002] The existing calcium carbide unloading and transfer process mainly utilizes a winch to drive a steel wire rope to pull a calcium carbide trolley along a track. Specifically, there are two transfer methods: First, patent document CN116294634A discloses a robot-based method for calcium carbide recycling, transfer, and cooling. In this method, a steel wire rope pulls a calcium carbide trolley filled with molten calcium carbide to the cooling zone. An overhead crane clamps the calcium carbide pot filled with molten calcium carbide and transfers it to a support in the cooling zone. The cooled calcium carbide is then removed from the mold, and the empty calcium carbide pot is returned to the calcium carbide trolley for replacement. Although this method has a simple trolley movement path, a small number of trolleys, and does not require changing the steel wire rope during transfer, it requires coordination with the overhead crane to complete the three tasks of pot transfer, removal of molten calcium carbide, and pot replacement in a short time, resulting in excessively high crane operating frequency and a heavy production load. Second, patent document CN215247... 627U discloses a calcium carbide tapping, transfer, and storage system. This system utilizes a track-changing device on the track. Before changing tracks, the steel cable pulling the calcium carbide trolley needs to be manually unhooked and moved to another track. Then, the steel cable of the other track is manually hooked onto the calcium carbide trolley, allowing it to move between the inner and outer ring tracks. This facilitates direct cooling of the calcium carbide trolley filled with molten calcium carbide on the track. After cooling, the calcium carbide pot on the trolley is transferred by an overhead crane to the pot elevator for subsequent turning and demolding. After demolding, the empty calcium carbide pot returns to the calcium carbide trolley. Although the overhead crane has low working pressure, the connection between the winch and the calcium carbide trolley requires manual unhooking of the steel cable. Furthermore, the direct cooling of the calcium carbide trolley on the track after tapping makes the transfer position of the trolley change frequently and lacks flexibility, resulting in difficulty in scheduling the trolley during tapping and thus affecting production efficiency. Summary of the Invention

[0003] To address the problems of low automation, poor scheduling timeliness, and low production efficiency in existing calcium carbide furnace tapping and transfer methods, this invention proposes a collaborative calcium carbide furnace tapping and transfer system using an RGV trolley and a mobile platform. The system includes a furnace body, an open-loop transfer track surrounding the furnace bore, and a cooling zone surrounding the transfer track on the side furthest from the furnace body. At least three parallel storage tracks are laid near the transfer track within the cooling zone. A receiving trolley carrying a calcium carbide pot can be arranged on each storage track. An RGV tractor is mounted on at least one storage track. An open section is formed between the storage track and the transfer track, with a horizontal track perpendicular to the transfer direction of the transfer track at the open section. At least one horizontal track is equipped with... A set of mobile platforms, each equipped with at least one mobile track, wherein one end of an RGV tractor can be attached to one end of a receiving trolley on a storage track and pulled to run on the storage track and the mobile track. When the receiving trolley on the mobile track is detached from the RGV tractor, the receiving trolley can be transferred by the mobile platform to connect with a transfer track. Both ends of the open section of the transfer track are equipped with hooking mechanisms, and both ends of the transfer track are equipped with winches. The grippers on the hooking mechanisms can automatically clamp the neck of the wire rope on the winch and attach or detach it from the head and tail ends of the receiving trolley. After attaching the wire rope, the receiving trolley can run on the transfer track and its corresponding mobile track.

[0004] A crane system is installed above the cooling zone. The crane system can separate the cooled calcium carbide from the calcium carbide pot and demold it.

[0005] The hooking mechanism includes a base, on which a first drive unit is provided. The drive end of the first drive unit is connected to a movable guide frame. A second drive unit is provided on the movable guide frame. A gripping mechanism is provided on the swing shaft of the second drive unit. The second drive unit can drive the gripping mechanism to swing up and down. When it swings to the upper position, the gripping mechanism can be perpendicular to the horizontal ground. The gripping mechanism includes a third drive unit. The movable end of the third drive unit is provided with a gripper. The gripper can grip the neck of the wire rope on the winch and is driven by the third drive unit to achieve the lifting action.

[0006] The mobile platform includes a mobile base, a power wheel assembly at the lower end of the mobile base, and a mobile track on the mobile base. The power wheel assembly moves on the horizontal track to realize the docking action between the mobile track and the transfer track and / or the storage track.

[0007] The transfer track includes an independent inner transfer track and an outer transfer track, with the furnace body located in the area between the inner and outer transfer tracks.

[0008] The open section of the transfer track is also equipped with a rope lifter at the joint of the guide rails at both ends. The rope lifter can grab the steel wire rope attached to the receiving trolley on the transfer track and lift it upward.

[0009] This invention also proposes a collaborative method for transferring calcium carbide from the furnace using an RGV trolley and a mobile platform, which includes the following steps:

[0010] S1. Cart Out of Warehouse: The mobile platform is controlled by the control system to move and dock with the receiving trolley that is ready to leave the warehouse and carries the empty calcium carbide pot on the storage track. The RGV tractor waiting on the storage track is attached to the receiving trolley. After the RGV tractor transfers the receiving trolley from the storage track to the mobile track, the RGV tractor is disengaged from the receiving trolley.

[0011] S2, Trolley Rope Hanging: The control system controls the movement of the mobile platform, connecting the receiving trolley carrying the empty calcium carbide pot on the mobile track to the transfer track that facilitates receiving materials. The claws on the hooking mechanism clamp the neck of the wire rope and drive it to hook onto the head and tail ends of the receiving trolley respectively.

[0012] S3. Receiving and Transferring Material: The winch drives the receiving trolley to transfer the material to the furnace hole of the furnace body to wait for it to be discharged. When it is discharged, the calcium carbide liquid is discharged from the furnace hole by the calcium carbide pot on the receiving trolley. After the discharge is completed, the winch drives the receiving trolley full of calcium carbide liquid to transfer it to the moving track through the transfer track.

[0013] S4. Rope removal and transfer: The grippers on the drive hook mechanism clamp the steel wire ropes attached to the head and tail ends of the receiving trolley respectively. After the grippers are lifted to disengage the steel wire ropes from the receiving trolley, the grippers return to the initial position. The control system controls the moving platform to move horizontally and transfer the receiving trolley filled with calcium carbide liquid to dock with a suitable empty storage track.

[0014] S5. Cooling upon entry into storage: The RGV tractor waiting on the docking storage track is connected to the receiving trolley filled with calcium carbide liquid on the moving track. The RGV tractor sends the receiving trolley into the storage track for cooling. After the RGV tractor automatically disengages from the receiving trolley, it returns to the moving track and can be transferred by the moving platform to dock with the storage track ready for exit.

[0015] S6. Demolding of calcium carbide: The overhead crane system separates and demolds the calcium carbide that has been cooled to a suitable temperature on the storage track from the calcium carbide pot on the receiving trolley.

[0016] Steps S1 to S6 that are sequentially connected are executed in sequence, while steps that are not sequentially connected can be executed in parallel or in any order.

[0017] In steps S1 to S6, when the receiving trolley is in the state of attaching a steel wire rope on the transfer track, and there is an obstacle to the docking of the moving platform with other tracks, the rope lifting device provided at the docking point of the guide rails at both ends of the open section of the transfer track can grab the attached steel wire rope and be lifted upward by the winch.

[0018] The beneficial effects of this invention are:

[0019] A. The mobile platform can connect with the transfer and storage tracks via the mobile track, and the material is fed into the storage track for cooling by the RGV tractor and the receiving trolley. This does not affect the connection between other storage or transfer tracks and the mobile platform, making the material receiving and transfer scheduling of the receiving trolley more flexible. At the same time, it greatly reduces the workload of the overhead crane system, making the overall furnace transfer efficiency higher and improving the overall scheduling capability of the system.

[0020] B. By using the hook mechanism set at the docking point of the transfer track, the wire rope on the winch can be automatically hooked and automatically detached from the head and tail ends of the docked receiving trolley, reducing the labor intensity of personnel and improving the automation level of trolley transfer.

One end of the RGV tractor 40 can be hooked onto one end of the receiving trolley 7 on the storage track 20 and pulled to run on the storage track 20 and the mobile track 10. When the receiving trolley 7 on the mobile track 10 is detached from the RGV tractor 40, the receiving trolley 7 can be transferred by the mobile platform 6 to dock with the transfer track 2. The two ends of the open section of the transfer track 2 are equipped with hooking mechanisms 9, and both ends of the transfer track 2 are equipped with winches 3. The grippers 96 on the hooking mechanisms 9 can automatically grip the neck of the wire rope 31 on the winch 3 and hook or detach it from the head and tail ends of the docked receiving trolley 7. After hooking the wire rope, the receiving trolley 7 can run on the transfer track 2 and its corresponding mobile track 10.

[0031] Furthermore, a crane system 5 is installed above the cooling zone 4. The crane system 5 can separate the cooled calcium carbide from the calcium carbide pot 8 on the receiving trolley 7 and demold it. Preferably, the crane system 5 is an intelligent unmanned crane system that can be automatically operated by the control system to perform the mold opening and demolding actions.

[0032] See Figure 2 The hook mechanism 9 includes a base 91, on which a first drive unit 92 is provided. The drive end of the first drive unit 92 is connected to a movable guide frame 93. A second drive unit 94 is provided on the movable guide frame 93. A gripping mechanism is provided on the swing shaft of the second drive unit 94. The second drive unit 94 can drive the gripping mechanism to swing up and down. When it swings to the upper position, the gripping mechanism can be perpendicular to the horizontal ground. The gripping mechanism includes a third drive unit 95. The movable end of the third drive unit 95 is provided with a gripper 96. The gripper 96 can grip the neck of the wire rope 31 on the winch 3 and is driven by the third drive unit 95 to achieve lifting and lowering.

[0033] Furthermore, the first drive unit 92 and the third drive unit 95 are preferably electric cylinder structures, the second drive unit 94 is preferably a servo motor, and the gripper 96 is preferably a pneumatic gripper structure. During the rope removal operation, the first drive unit 92 drives the movable guide 93 to extend to the position below the wire rope 31 attached to the receiving trolley 7, the second drive unit 94 drives the gripping mechanism to swing upward until the jaws of the gripper 96 face upward, the third drive unit 95 drives the gripper 96 to rise to the neck of the wire rope 31, the gripper 96 closes to grip the wire rope 31, the gripper 96 continues to rise to disengage the wire rope 31 from the attachment position of the receiving trolley 7, the first drive unit 92 drives the movable guide 93 to return to the initial position, and the third drive unit 95 and the second drive unit 94 drive the gripper 96 holding the wire rope 31 to return to the initial position.

[0034] See Figure 3 The mobile platform 6 includes a mobile base 61, a power wheel set 62 at the lower end of the mobile base 61, and a mobile track 10 on the mobile base 61. The power wheel set 62 moves on the horizontal track 50 to realize the docking action between the mobile track 10 and the transfer track 2 or the storage track 20.

[0035] See Figure 4 The docking end of the RGV tractor 40 is equipped with a hook 41, which can automatically hook onto the docked receiving trolley 7. Its structure can be selected from conventional existing technologies, which will not be elaborated here. It should be emphasized that when the RGV tractor 40 needs to hook onto another receiving trolley 7 on a storage track 20, the movable track 10 on the movable platform 6 first docks with the RGV tractor 40, transferring the RGV tractor 40 onto the movable track 10. Then, the movable track 10 is moved to dock with the selected storage track 20, allowing the RGV tractor 40 to be transferred to that storage track 20 and dock with the selected receiving trolley 7.

[0036] In this embodiment, the transfer method of the transfer system includes the following steps:

[0037] S1. Cart Out of Warehouse: The mobile platform 6 is moved by the control system. The mobile track 10 is connected to the receiving trolley 7 on the storage track 20, which is ready to be out of the warehouse and carries the empty calcium carbide pot 8. The RGV tractor 40 waiting on the storage track 20 is attached to the receiving trolley 7. After the RGV tractor 40 transfers the receiving trolley 7 from the storage track 20 to the mobile track 10, the RGV tractor 40 is disengaged from the receiving trolley 7.

[0038] S2, Trolley rope: The control system controls the movement of the mobile platform 6, and connects the receiving trolley 7 carrying the empty calcium carbide pot 8 on the mobile track 10 with the transfer track 2 which is convenient for receiving materials. The claws 96 on the hook mechanism 9 clamp the neck of the wire rope 31 and drive it to hook to the head and tail ends of the receiving trolley 7 respectively.

[0039] S3, receiving and transferring: the winch 3 drives the receiving trolley 7 to transfer to the furnace eye of the furnace body 1 to wait for the furnace to be discharged. When the furnace is discharged, the calcium carbide pot 8 on the receiving trolley 7 is used to collect the calcium carbide liquid discharged from the furnace eye. After the furnace is discharged, the winch 3 drives the receiving trolley 7 filled with calcium carbide liquid to transfer to the moving track 10 through the transfer track 2.

[0040] S4. Rope removal and transfer: The grippers 96 on the drive hook mechanism 9 respectively grip the steel wire ropes 31 attached to the head and tail ends of the receiving trolley 7. After the grippers 96 are lifted to disengage the steel wire ropes 31 from the receiving trolley 7, the grippers 96 return to the initial position. The control system controls the moving platform 6 to move horizontally and transfer the receiving trolley 7 filled with calcium carbide liquid to dock with the appropriate empty storage track 20.

[0041] S5. Cooling upon entry into storage: The RGV tractor 40 waiting on the docking storage track 20 is connected to the receiving trolley 7 filled with calcium carbide liquid on the moving track 10. The RGV tractor 40 sends the receiving trolley 7 into the storage track 20 for cooling. After the RGV tractor 40 automatically disengages from the receiving trolley 7, it returns to the moving track 10 and can be transferred by the moving platform 6 to dock with the storage track 20 that is ready to be released from storage.

[0042] S6, Demolding of calcium carbide: The overhead crane system 5 separates the calcium carbide cooled to a suitable temperature on the storage track 20 from the calcium carbide pot 8 on the receiving trolley 7 and demolds it.

[0043] Steps S1 to S6 that are sequentially connected are executed in sequence, while steps that are not sequentially connected can be executed in parallel or in any order.

[0044] The transfer system and transfer method of this embodiment realize flexible transfer scheduling of the receiving trolley 7, while also greatly reducing the workload of the overhead crane system 5, reducing the labor intensity of personnel, improving the automation level of trolley transfer, and improving the overall transfer efficiency of the furnace.

[0045] Example 2

[0046] See Figure 5In the second embodiment of the present invention, based on the first embodiment, an additional parallel storage track 20 is laid near the transfer track 2 in the cooling zone 4, that is, four parallel storage tracks 20 are laid. Each storage track 20 can be equipped with a receiving trolley 7 carrying a calcium carbide pot 8. RGV tractors 40 are respectively installed on two of the storage tracks 20, and two sets of moving platforms 6 are installed on the horizontal track 50. A moving track 10 is installed on each moving platform 6. A rope lifter 30 is also provided at the guide rail docking point at both ends of the open section of the transfer track 2. The rope lifter 30 can grab the wire rope attached to the receiving trolley 7 on the transfer track 2 and lift it upward. The rope lifter 30 includes a drive unit and a rope clamping unit. The drive unit drives the rope clamping unit to swing to a vertical state and grabs the wire rope 31 through the rope clamping unit. Then, the lifting device of the drive unit lifts it upward, while the winch 3 cooperates to loosen the rope and raise the wire rope 31 upward.

[0047] In this embodiment, the two sets of mobile platforms 6 move independently and can dock with either the transfer track 2 or the storage track 20 individually. When the receiving trolley 7 is already running on the transfer track 2, the receiving trolley 7 is in the state of being hooked up with a steel wire rope. For the mobile platform 6 to dock smoothly with the storage track 20, the rope lifter 30 needs to grab the hooked steel wire rope 31, and the winch 3 needs to assist in raising the steel wire rope 31, thereby avoiding the mobile platform 6 so that it can dock with the storage track 20. In this embodiment, the setting of two sets of mobile platforms 6, two RGV tractors 40, and four storage tracks 20 makes the trolley transfer more flexible and the scheduling faster, which can adapt to the furnace output requirements of higher power furnaces 1.
