Description

Technical Field

[0002] The calcium carbide furnace is the main equipment for producing calcium carbide and is an important piece of chemical production equipment. The calcium carbide furnace requires...

[0003] The electrodes need to be continuously raised and lowered, while simultaneously obtaining real-time data on the length of the electrode extending into the calcium carbide furnace. Currently, the measurement and adjustment of electrode length largely rely on manual operation. Because the calcium carbide furnace operates in a high-temperature environment, operators face significant occupational health and safety risks, easily leading to personal injury accidents. Furthermore, manual measurement is limited by tool precision and operator experience, easily resulting in errors and failing to ensure accurate control of the electrode length. Additionally, manual measurement and adjustment of the electrode length are labor-intensive and inefficient.

This device includes a moving mechanism with an angle-adjusting component mounted on it, and a measuring component mounted on the angle-adjusting component. The measuring component measures the length of an electrode extending into the calcium carbide furnace. The components cooperate to form a right-angled triangle, and the electrode length is calculated based on determined parameters. While this solution reduces human error during measurement through the auxiliary measuring device, it still relies on manual measurement, which presents problems of high risk and low efficiency in manual operation.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0039] An intelligent inspection robot for fiber testing at the working end of an electrode in a calcium carbide furnace, such as Figure 1 As shown, it includes a moving mechanism 100 and a feeding mechanism 200, one end of which is fixed to the moving mechanism 100 and the other end of which is used to clamp the auxiliary measuring rod 300.

[0040] 200 for the receiving organization Figure 2As shown, the system includes a first rotating assembly 210, a lifting assembly 220, and a second rotating assembly 230 arranged sequentially from bottom to top. The bottom of the first rotating assembly 210 is fixedly connected to the upper surface of the housing of the moving mechanism 100, and its top is connected to the lifting assembly 220. A first rotary motor is installed inside the first rotating assembly 210 to drive the feeding mechanism 200 to rotate around a vertical axis. The bottom of the lifting assembly 220 is connected to the first rotating assembly 210, and its top is connected to the second rotating assembly 230. A linear cylinder is installed inside the lifting assembly 220 to adjust the height of the second rotating assembly 230. The second rotating assembly 230 is equipped with a second rotary motor to drive the auxiliary measuring rod 300 to rotate in the horizontal axis direction.

[0041] More specifically, the structure of the first rotating component 210 is as follows: Figure 3 and Figure 6 As shown, the assembly includes a circular base 211 whose bottom is fixedly connected to the moving mechanism 100; a first housing 212 fixed to the upper surface of the base 211 and having an internal installation space; and a first rotary motor located inside the first housing 212 and whose bottom is fixedly connected to the base 211. The top output shaft of the first rotary motor is spaced apart from the inner sidewall of the first housing 212. A circular through hole is provided at the top of the first housing 212, and the output shaft of the first rotary motor 213 is located in the through hole and fixedly connected to the bottom of the lifting assembly 220.

[0042] The structure of the lifting assembly 220 is as follows Figure 4 and Figure 6 As shown, the assembly includes a transmission component 221 located at the bottom, a cylinder body 222 fixedly connected to the transmission component 221 at the bottom, and a piston 223 located inside the cylinder body 222. The bottom of the transmission component 221 is located in the through hole of the first housing 212 and connected to the output shaft of the first rotary motor 213, used to drive the lifting assembly 220 to rotate as a whole. The bottom of the cylinder body 222 also has an opening for connecting to an external air source (not shown in the figure). The cylinder body 222 has a hollow receiving cavity inside, the bottom of the piston 223 is located in the receiving cavity, and the top can extend out of the cylinder body 222 to drive the second rotary assembly 230 to move up and down as a whole. The rotation axis of the first rotary assembly 210 coincides with the axis of the lifting assembly 220.

[0043] The structure of the second rotating component 230 is as follows: Figure 5As shown, the assembly includes a second rotary motor 231 fixedly connected to the lifting assembly 220, a transmission shaft 232 with one end connected to the output shaft of the second rotary motor, and a gripper 233 fixedly connected to the other end of the transmission shaft 232. The output shaft of the second rotary motor 231 is located in the horizontal direction, and the gripper 233 is driven by the transmission shaft 232 to achieve rotation in the horizontal axis direction. The gripper 233 includes three columns arranged in an equilateral triangle, and each column is provided with an outwardly protruding, circular component for clamping the auxiliary measuring rod 300.

[0044] The feeding mechanism 200 is used to clamp the auxiliary measuring rod 300 and drive the auxiliary measuring rod 300 to rotate, lift, and move along the vertical axis, as well as rotate along the horizontal axis. A cross-sectional view of the feeding mechanism 200 is shown below. Figure 6 As shown, the bottom of the feeding mechanism 200 is fixed to the moving mechanism 100 via the base 211. A first rotary motor 213 located within the first housing 212 drives the rotation of the lifting assembly 220. An external air source drives the piston 223 of the lifting assembly 220 to move linearly within the cylinder body 222, thereby driving the second rotary assembly 230 to move up and down. Finally, the second rotary motor 231 of the second rotary assembly 230 drives the gripper 233 holding the auxiliary measuring rod 300 to rotate along the horizontal axis. Therefore, the feeding mechanism 200 can drive the auxiliary measuring rod 300 to rotate along the vertical axis, move up and down vertically, and rotate along the horizontal axis.

[0045] While the aforementioned feeding mechanism 200 can achieve vertical lifting, the gripper only serves to fix the auxiliary measuring rod and cannot fully simulate the "insertion into the calcium carbide furnace" action during measurement. Therefore, further improvements to the gripper 233 are needed. The applicant has designed a clamping assembly 240 to replace the original gripper 233. The structure of the clamping assembly 240 is as follows... Figure 7 As shown, the assembly includes a second housing 241 fixedly connected to the drive shaft 232 of the second rotating assembly 230, a third rotating motor 242 fixed inside the second housing 241, a crossbar 243 connected to the third rotating motor 242 via gear transmission, and a clamping member 244 fixed to the crossbar 243. The clamping assembly 240 is used to clamp the auxiliary measuring rod 300 and drive the auxiliary measuring rod 300 to move linearly along its axial direction. The motion principle is as follows: Figure 8As shown, a driving wheel is fixed on the output shaft of the third rotary motor 242, and driven wheels that mesh with the driving wheel are fixed on the crossbar 243. During the rotation of the third rotary motor 242, the driving wheel moves clockwise or counterclockwise, and the driven wheels drive the crossbar 243 to rotate in the opposite direction. The clamping members 244 on the crossbar 243 rotate with the crossbar 243, driving the auxiliary measuring rod to move linearly along its axis during rotation. It should be noted that the three clamping members 244 are located at the three vertices of an equilateral triangle. The auxiliary measuring rod 300 has two clamping members 244 on one side and one clamping member 244 on the other side. The direction of movement of the auxiliary measuring rod 300 is determined by the rotation direction of the two clamping members 244 rotating on the same side. Therefore, the improved feeding mechanism 200, in conjunction with the clamping assembly 240, can simulate the "insertion-tilt-re-insertion" action during manual measurement.

[0046] The structure of the moving mechanism 100 is as follows Figure 9 and Figure 10 As shown, it mainly includes a third housing 110 and a moving component 120. The top of the third housing 110 is flat and is used to weld the base 211 of the feeding mechanism 200. It is hollow inside and divided by a partition, and contains a power supply (not shown in the figure) and a circuit board (not shown in the figure). The third housing 110 has a rectangular structure, and the moving component 120 is set at the four corners of the bottom. The third housing 110 mainly provides installation space for the power supply and the circuit board, and can mount corresponding sensors at preset positions to facilitate data acquisition. The moving component 120 mainly includes a fourth rotary motor 121 and a roller 122. The rotation of the fourth rotary motor 121 drives the roller 122, which is fixed to the output shaft, to rotate. The power supply is electrically connected to the circuit board, which can receive external control signals to control the rotation of the first rotary motor 213, the second rotary motor 231, the third rotary motor 242, and the fourth rotary motor 121, as well as the lifting component 220. The moving mechanism 100 can move in a linear direction with the preset guide rail, and can collect the on-site environmental conditions of the calcium carbide furnace during the movement.

[0047] During the measurement of the electrode working end length, the contact point and angle of the auxiliary probe are determined through sensor feedback, and the length of the electrode working end is calculated by combining this with known electrode position information. More specifically, for example... Figure 11 As shown, in Figure 11In the diagram, the rectangle on the left represents the electrode, h is the length of the electrode extending into the calcium carbide furnace, α is the rotation angle of the auxiliary measuring rod after rotation from its initial state, and d is the distance between the intelligent inspection robot and the electrode. During measurement, the intelligent inspection robot maintains a certain distance d between itself and the electrode around the calcium carbide furnace and moves in a circular tracking pattern. By extending the auxiliary measuring rod into the calcium carbide furnace and making contact with the electrode, the rotation angle α, which is measured by the encoder on the second rotating component 230, is then calculated using the formula h = d * arctanα. By measuring h multiple times at different points, the true length of the electrode extending into the calcium carbide furnace can be effectively obtained.

[0048] An intelligent inspection system, such as Figure 12 As shown, the system includes an intelligent inspection robot and a server connected to the robot. The intelligent inspection robot includes a power supply, a control module, a communication module, a camera, an environmental monitoring module, a feeding mechanism, a moving mechanism, and an obstacle avoidance module. The camera collects video data, the environmental monitoring module collects environmental data, and the communication module transmits both video and environmental data to the server. The server includes an early warning module, an algorithm analysis module, a database, and a data processing module. The database stores video and environmental data, the algorithm analysis module analyzes the data and sends the results to the early warning and data processing modules, and the server also receives external control commands and transmits them to the robot's communication module, where the control module receives and executes the commands. The server is also connected to a display for showing radio frequency data, environmental data, and analysis results.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
