Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical equipment, and relates to an automatic molten steel temperature measuring and sampling system for a continuous casting tundish car. Background Art

[0002] In the production of metallurgy and foundry industries, it is necessary to measure the temperature of molten steel and take samples of molten steel during the smelting process of molten steel. Most of the existing technologies adopt manual temperature measurement and sampling, that is, a temperature measurement probe or a sampler is installed on a temperature measurement rod or a sampling gun rod and then inserted into the molten steel liquid surface to measure the temperature of molten steel or take samples. In order to solve the potential safety hazards of high-temperature burns and molten steel splashing during the process of manual temperature measurement and sampling, it is very necessary to develop an automatic temperature measurement and sampling system. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automatic molten steel temperature measuring and sampling system for a continuous casting tundish car.

[0004] The technical solution of the utility model is as follows:

[0005] The automatic molten steel temperature measuring and sampling system for a continuous casting tundish car includes a probe automatic feeding device, a robot, a robot rotary platform, a temperature measurement gun rack and a temperature measurement gun. The robot is installed on the robot rotary platform, the probe automatic feeding device is arranged on the left side of the robot and the robot rotary platform, and the temperature measurement gun rack is arranged on the right side of the robot and the robot rotary platform. The probe automatic feeding device includes a probe storage mechanism, a probe automatic blanking mechanism, a probe conveying mechanism, a probe positioning bracket, a probe clamping mechanism and a temperature measurement gun guiding mechanism. The probe storage mechanism is partitioned into 5 cartridges, and the cartridges are used to store temperature measurement probes and samplers. A probe automatic blanking mechanism is installed below each cartridge, and a probe conveying mechanism is installed at the bottom of the probe automatic blanking mechanism to convey the probes separated from each probe automatic blanking mechanism to the probe positioning bracket. A probe clamping mechanism and a temperature measurement gun guiding mechanism are installed on the center line of the probe positioning bracket, and the temperature measurement gun guiding mechanism is arranged at the front end of the probe clamping mechanism.

[0006] The robot rotary platform includes a base, a slewing bearing, a servo motor and a robot mounting bracket. The bottom surface of the slewing bearing is installed on the base, the servo motor is connected to the driving end of the slewing bearing, and the robot mounting bracket is connected to the top of the slewing bearing. The servo motor drives the slewing bearing to rotate, driving the robot to rotate around the slewing bearing, thereby increasing the working range of the robot.

[0007] The temperature measurement gun rack includes two sets of temperature measurement guns and a material rack. The temperature measurement guns are stored on the left side of the material rack when the system is on standby.

[0008] Furthermore, the automatic temperature measurement and sampling system further includes a quick-change protective cover and a quick-change protective cover cylinder. The quick-change protective cover is arranged at the front end of the rack, and the quick-change protective cover cylinder is connected to the quick-change protective cover. The quick-change protective cover cylinder drives the quick-change protective cover to close, preventing dust and other debris from falling on the tool side of the quick-change device at the front end of the temperature measuring gun. When the system is operating, the quick-change protective cover cylinder drives the quick-change protective cover to open, and the robot picks up the temperature measuring gun through the robot side of the quick-change device installed on the sixth axis.

[0009] The beneficial effects of the present utility model: Due to the adoption of the automatic temperature measurement and sampling system, the operating workers only need to work in the control room, effectively solving the safety hazards of high-temperature burns and molten steel splashing during the manual temperature measurement and sampling process, and at the same time, it can further reduce the number of employees and increase efficiency.

[0019] The content of the utility model will be further described below in conjunction with the embodiments of the attached drawings.

[0020] Figure 1 , Figure 2 As shown in the figure: The automatic molten steel temperature measurement and sampling system for the continuous casting ladle car includes a probe automatic feeding device 1, a temperature measuring gun rack 2, a robot rotating platform 3 and a robot 31, and a temperature measuring gun 4. The robot 31 is installed on the robot rotating platform 3. The probe automatic feeding device 1 is arranged on the left side of the robot 31 and the robot rotating platform 3, and the temperature measuring gun rack 2 is arranged on the right side of the robot 31 and the robot rotating platform 3.

[0021] Figures 3 to 6 As shown in the figure: The probe automatic feeding device 1 includes a probe storage mechanism 6, a probe automatic blanking mechanism 7, a probe conveying mechanism 8, a probe positioning bracket 9, a probe clamping mechanism 11, and a temperature measuring gun guiding mechanism 10. The probe storage mechanism is partitioned into 5 boxes, and the boxes are used to store temperature measuring probes and samplers. A probe automatic blanking mechanism 7 is installed below each box. The bottom of the probe automatic blanking mechanism is installed with a probe conveying mechanism 8 to convey the probes separated by each probe automatic blanking mechanism to the probe positioning bracket 9. A probe clamping mechanism 11 and a temperature measuring gun guiding mechanism 10 are installed on the center line of the probe positioning bracket 9, and the temperature measuring gun guiding mechanism 10 is arranged at the front end of the probe clamping mechanism 11.

[0022] Figure 7 As shown in the figure: The robot rotating platform 3 includes a base 27, a slewing bearing 29, a servo motor 28, and a robot mounting bracket 30. The bottom surface of the slewing bearing 29 is installed on the base 27, the servo motor 28 is connected to the driving end of the slewing bearing 29, and the robot mounting bracket 30 is connected to the top of the slewing bearing 29.

[0023] Figure 8 As shown in the figure: The temperature measuring gun rack 2 includes two sets of temperature measuring guns 4, a material rack 37, a quick-change protective cover 34, and a quick-change protective cover cylinder 33. The temperature measuring gun 4 is arranged on the left side of the material rack 37, the quick-change protective cover 34 is arranged at the front end of the material rack 37, and the quick-change protective cover cylinder 33 is connected to the quick-change protective cover 34.

[0024] Taking the temperature measuring system as an example, the working process of the system is as follows:

[0025] When the automatic temperature measuring and sampling system is started and the robot 31 and the robot rotary platform 3 stop at the original position, as Figure 7 shown, the quick-change protective cover cylinder 33 drives the quick-change protective cover 34 to open, and the robot 31 picks up the temperature measuring gun 4 through the quick-change device robot side 32 installed on the sixth axis.

[0026] 2) When the robot 31 brings the temperature measuring gun 4 to the probe automatic feeding device 1 to automatically install the probe, as Figure 1 shown. At the lower part of the temperature measuring probe storage box 12 inside the probe automatic feeding device 1, the lower probe automatic blanking mechanism 7 of the temperature measuring probe is pushed by the dividing plate pushing cylinder 14 to divide out 1 temperature measuring probe 16 from the dividing plate 15. As Figure 4 shown, the divided temperature measuring probe falls on the lower probe conveying mechanism 8. As Figure 6 shown, the motor 23 of the probe conveying mechanism 8 drives the synchronous belt 24 to drive the sprocket 26 to drive the chain 25, and conveys the temperature measuring probe 16 to the probe positioning bracket 9. At this time, the bottom probe clamping cylinder 20 of the probe clamping mechanism 11 pushes the probe clamping jaws 19 to close, clamping the temperature measuring probe 16. At the same time, the bottom temperature measuring gun guiding cylinder 22 of the temperature measuring gun guiding mechanism 10 pushes the temperature measuring gun guiding cone sleeve 21 to close. As Figure 1 shown, then the robot 31 moves with the temperature measuring gun 4, inserts the temperature measuring gun rod 36 into the temperature measuring probe 16. After reaching the appropriate position, the bottom probe clamping cylinder 20 of the probe clamping mechanism 11 pushes the probe clamping jaws 19 to open, and at the same time, the bottom temperature measuring gun guiding cylinder 22 of the temperature measuring gun guiding mechanism 10 pushes the temperature measuring gun guiding cone sleeve 21 to open. Then the robot 31 starts to move, removes the temperature measuring gun 4 and installs the temperature measuring probe 16.

[0027] 3) After the robot 31 automatically installs the temperature measuring probe 16 with the temperature measuring gun 4, the robot rotary platform 3 is driven by the servo motor 28 to rotate the slewing bearing 29, thereby driving the robot 31 to rotate around the slewing bearing to the temperature measuring and sampling station. As Figure 2 shown, the robot 31 starts to move, inserts the temperature measuring gun 4 and the temperature measuring probe 16 into the ladle car temperature measuring hole 5, and completes the temperature measuring action.

[0028] 4) The robot 31 retracts the temperature measuring gun 4. After the temperature measuring probe 16 is taken away, the robot rotary platform 3 returns to the original position. The robot 31 places the temperature measuring gun 4 on the left side of the rack 37, and the robot 31 returns to the starting position. The quick-change protective cover cylinder 33 drives the quick-change protective cover 34 to close, thus completing one instance of the temperature measuring system.

[0029] Figure 1 As shown in the figure: The robot rotary platform 3 is in the original position. The probe automatic feeding device 1 has provided the probe to the positioning fork 18 of the positioning bracket 9 as required. The probe clamping mechanism 11 has clamped the probe. The robot 31 inserts the temperature measuring gun 4 with the probe through the guiding mechanism 5 and installs the probe.

[0030] Figure 2 As shown in the figure: The robot rotary platform 3 is in the temperature measuring and sampling station. The robot 31 inserts the temperature measuring gun 4 with the installed probe into the temperature measuring hole 5 of the tundish car to start temperature measuring and sampling.

[0031] Figure 3 As shown in the figure: The probe automatic blanking mechanism 7 separates 1 probe from below the probe storage mechanism 6 through the material distribution plate 15 and transfers it onto the probe conveying mechanism 8. The probe conveying mechanism 8 conveys the probe to the probe positioning bracket 9. The probe clamping mechanism 11 clamps the probe, and the guiding cone sleeve 21 of the temperature measuring gun guiding mechanism 10 closes.

[0032] Figure 4 As shown in the figure: The probe automatic blanking mechanism 7 uses the material distribution plate pushing cylinder 14 to push the material distribution plate 15 to separate 1 probe (temperature measuring probe 16 or sampler 17).

[0033] Figure 5 As shown in the figure: The probe is already on the positioning fork 18 of the positioning bracket 9. The probe clamping cylinder 20 pushes the probe clamping jaw 19 to close, thereby clamping the probe. The temperature measuring gun guiding cylinder 22 pushes the guiding cone sleeve 21 of the temperature measuring gun to close.

[0034] Figure 6 As shown in the figure: The motor 23 drives the synchronous belt 24 to drive the sprocket 26 to drive the chain 25, and conveys the probe to the probe positioning bracket 9.

[0035] Figure 7 As shown in the figure: The outer ring of the slewing bearing 29 is fixed on the slewing bearing base 27. The robot base 30 is installed on the inner ring of the slewing bearing 29. The robot 31 is fixed on the robot base 30. The quick-change device robot side 32 is installed on the sixth axis of the robot 31. The servo motor 28 drives the slewing bearing 29 to rotate, so that the robot base 30 rotates, which can increase the working range of the robot.

[0036] Figure 8As shown in the figure: Two sets of temperature measuring guns 4 are stored on the rack 37. The quick-change protective cover cylinder 33 pushes the quick-change protective cover 34 to close, thereby preventing dust or foreign objects from falling on the tool side 35 of the quick-change device. When the automatic temperature measurement and sampling system is started, the quick-change protective cover cylinder 33 pushes the quick-change protective cover 34 to open.
