Description

Technical Field

[0001] This utility model relates to the technical field of an automatic steel rod replacement device for a calcium carbide furnace, and belongs to the category of an automatic rod replacement device for a calcium carbide furnace. Background Technology

[0002] In the calcium carbide production process, steel rods, as crucial tools for tapping out of the furnace, endure extremely high temperatures and pressures, making their wear and tear inevitable. As production continues, steel rods gradually wear down, making regular replacement essential to ensure production efficiency and safety. However, currently, calcium carbide enterprises generally rely on manual lifting and placement when replacing steel rods. This traditional practice is not only inefficient but also poses potential safety risks. Workers must manually move the heavy steel rods and carefully place them on tool racks; the entire process is time-consuming, labor-intensive, and prone to accidents due to improper operation. To improve rod replacement efficiency, reduce worker fatigue, and ensure operational safety, an automated steel rod replacement technology for calcium carbide furnaces has been proposed.

[0003] Patent CN218495838 U discloses an electric rod changing device for a calcium carbide furnace. This device includes a frame, wheels, a lifting rod, a crossbar, hooks, a chain, and a linear drive mechanism. Wheels are located at the bottom of the frame. A horizontally positioned crossbar is connected to the front end of the lifting rod. Hooks are connected to the left and right sides of the crossbar via chains. The rear end of the lifting rod is hinged to the top of the frame. The cylinder of the linear drive mechanism is hinged to the top of the frame, and the piston rod is hinged to the middle of the lifting rod. When the piston rod extends outward, it pushes the lifting rod to rotate upward around the hinge axis between the lifting rod and the frame. This utility model patent achieves electric control of the rod changing operation, greatly reducing labor intensity. However, the entire rod changing operation still requires manual pushing of the electric rod changing device to the work area, and the hooking and unhooking of the steel rods also requires manual operation. The entire operation requires 1-2 people to complete, resulting in a low degree of automation. Summary of the Invention

Detailed Implementation

[0021] The preferred embodiments of this utility model are described in detail below.

[0022] Example 1: This utility model provides an automatic steel rod replacement device for calcium carbide furnace, which mainly includes a calcium carbide furnace 5, a tool rack 2, a circular track 4, a drive mechanism 9, and a gripping mechanism.

[0023] The calcium carbide furnace 5 has a tool rack 2 at the furnace outlet 6, and a ring track 4 is provided above the tool rack 2. The ring track 4 is installed on the roof of the furnace outlet operation site and is fixedly connected to the steel beam 8 on the roof. The ring track 4 and the calcium carbide furnace 5 are concentrically arranged, and the diameter of the ring track 4 is larger than the diameter of the calcium carbide furnace 5.

[0024] A drive mechanism 9 is provided on the annular track 4. The drive mechanism 9 is connected to a gripping mechanism. The gripping mechanism mainly includes a connecting rod 10, a hook 11, a lifting ring 12, a crossbar 13, a chain 14, and a gripper 15. The bottom of the connecting rod 10 is provided with a hook 11, and the center of the crossbar 13 is provided with a lifting ring 12. The hook 11 and the lifting ring 12 are connected to each other. Both ends of the crossbar 13 are provided with vertically downward chains 14 of equal length. The free end of the chain 14 is provided with a gripper 15. When the two grippers 15 grip the steel rod 3 at the same time, a stable support structure is formed, which reduces the vertical sway of the steel rod 3 and ensures the stability of the steel rod 3 during transportation.

[0025] The hook 11 can be equipped with a lock. When the hook 11 is connected to the lifting ring 12, the lock closes to ensure safety and stability during the replacement of the steel rod 3.

[0026] One end of the connecting rod 10 is a fixed end, and the other end is an adjustable end. The fixed end of the connecting rod 10 is connected to the drive mechanism 9, and the adjustable end is equipped with a hook 11. During the process of gripping the steel rod 3, the extension and retraction of the connecting rod 10 can be controlled by the remote control system to achieve precise adjustment.

[0027] The following is combined with Figure 1-2 The system described in this utility model will be further described in detail.

[0028] The calcium carbide furnace 5 is a cylindrical structure. Each calcium carbide furnace 5 has 3 outlets 6. The three outlets 6 are arranged at a 120° angle on the same horizontal plane. Each outlet 6 extends outward 1-2 meters to a position where an outlet platform 1 is provided. The outlet platform 1 is provided with a tool rack 2, and the outlet steel rod 3 is placed on the tool rack 2.

[0029] The calcium carbide furnace 5 also has a steel rod placement area 7 at the furnace outlet. The steel rod placement area 7 is located directly below the circular track 4. The steel rod placement area 7 can be adjusted according to the on-site space. The center positions of the steel rods 3 on the steel rod placement area 7 and the steel rods 3 on the tool rack 2 are both aligned with the center line of the circular track 4.

[0030] In the calcium carbide tapping operation, the steel rod 3 is mainly used for processes such as poking the furnace hole and guiding the flow. The steel rod 3 is prone to deformation and wear in high-temperature environments. Therefore, it is necessary to replace the tapping steel rod 3 regularly. When the steel rod 3 on the tool rack 2 needs to be replaced, the operator in the tapping control room remotely starts the drive mechanism 9 through the control system. The drive mechanism 9 moves along the circular track 4 to the top of the tool rack 2. After the positioning mechanism fixes the drive mechanism 9, the remote control system starts the bottom connecting rod 10 of the drive mechanism 9 to extend downward and open the gripper 15. When the steel rod 3 is in the center of the gripper 15, the gripper 15 closes to grab the steel rod 3. The remote control system drives the connecting rod 10 to retract and pick up the steel rod 3. The control system starts the drive mechanism 9, and the drive mechanism 9 moves along the circular track 4 to the top of the steel rod placement area 7. After the positioning mechanism fixes the drive mechanism 9, the bottom connecting rod 10 of the drive mechanism 9 extends downward and places the steel rod 3 in the steel rod placement area 7. Then the gripper 15 is opened to place the scrap steel rod 3 in the designated position and the connecting rod 10 is retracted.

[0031] Restart the drive mechanism 9 and move it to adjust its position on the circular track 4. Move the drive mechanism 9 to the top of the new steel rod area in the steel rod placement area 7. The connecting rod 10 extends downward and opens the gripper 15. When the new steel rod 3 is in the center of the gripper 15, close the gripper 15 to grab the steel rod 3. The connecting rod 10 retracts and lifts the steel rod 3. The remote control system restarts the drive mechanism 9. The drive mechanism 9 runs along the circular track 4 to the top of the tool rack 2. The positioning mechanism fixes the drive mechanism 9. Control the connecting rod 10 to extend downward and place the steel rod 3 in the designated position on the tool rack 2. Then open the gripper 15 and place the new steel rod 3 on the tool rack 2. Retract the connecting rod 10 to complete one steel rod replacement operation.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several changes and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
