Description

Technical Field

[0001] This invention relates to the field of metallurgical technology, and specifically discloses a sintering machine trolley elastic slide travel detection and reset system and method. Background Technology

[0002] The sintering machine is one of the important pieces of equipment in the sintering production process in the field of metallurgical technology. When the sintering machine trolley moves linearly along the planar guide rail, the oil plate of the elastic slide is in constant contact with the fixed slide under the elastic force of the internal support spring, thus forming a dynamic seal to prevent air leakage in the sintering negative pressure system. If air leakage occurs, it will cause fluctuations in the sintering quality of the ore and a surge in energy consumption.

[0003] The utility model patent with authorization announcement number CN210196451U discloses a bipolar elastic slide mutual compensation seal, including a sintering machine trolley. The inner side of the sintering machine trolley is movably connected to a self-lubricating channel sealing device, and the outer side of the sintering machine trolley is fixedly connected to a slide support beam. The top of the slide support beam is movably connected to a swing vortex flexible sealing device.

[0004] The elastic slide in the disclosed patent technology operates under high temperature and dust conditions. After long-term operation, the elastic slide is prone to deformation due to operational fatigue. In addition, the caking and accumulation of sintered ore dust and oil stains can easily cause some return trolley elastic slides to become stuck. The sealing oil plate of the elastic connection of the elastic slide will not be able to automatically complete the reset as originally designed. When the unreset sealing oil plate comes into contact with the fixed slide, a scraping accident will occur, which will cause the fixed slide to break and be damaged, leading to the shutdown of production equipment for maintenance and the entire material line to stop production. Summary of the Invention

[0005] This invention addresses the problem of unmanageable motion jamming in the elastic slide of a sintering machine trolley by providing a stroke detection and reset system and method for the elastic slide of a sintering machine trolley.

[0006] To achieve the above objectives, in a first aspect, the present invention provides the following technical solution:

[0007] A sintering machine trolley elastic slide travel detection and reset system includes a sintering machine trolley, with its base fixed to an elastic slide. The elastic slide is connected to a sealing oil plate via a support spring. A travel detection mechanism is installed above the sealing oil plate, electrically connected to a controller. The controller is electrically connected to a main control display and a reset actuator. The travel detection mechanism can detect the reset status of the sealing oil plate in real time and transmit the status to the controller. If the sealing oil plate fails to reset normally, the controller will control the actuator to force the sealing oil plate to reset and transmit the reset status to the main control display in real time, providing timely feedback to the on-site operators. This invention, by using a travel detection mechanism and a reset actuator, can automatically detect the working status of the elastic slide and accurately reset abnormal elastic slides, effectively avoiding accidents caused by fixed slide breakage due to elastic slide abnormalities, greatly improving the stability of the sintering machine trolley operation, and further ensuring production efficiency.

[0008] Preferably, the stroke detection mechanism includes a probe wheel connected to one end of a transmission rod. A rotating shaft is installed in the middle of the transmission rod, and touch sensors are installed on both sides of the other end of the transmission rod. The touch sensors are electrically connected to the controller. When the sealing oil plate abnormally resets, one or both ends of the sealing oil plate will be higher than the normal reset height, causing the sealing oil plate to push the probe wheel. The probe wheel drives the transmission rod to rotate along the rotating shaft in the middle, causing the transmission rod to press the touch sensors, thereby generating an abnormal reset electrical signal. The stroke detection mechanism has a simple structure, flexible configuration, and high reliability. It can be applied to various harsh working environments, thus ensuring accurate detection of the elastic slide. Furthermore, the high sensitivity of the stroke detection mechanism can improve the overall system's responsiveness to abnormal resets.

[0009] Preferably, the tactile sensor is electrically connected to the controller, the controller is electrically connected to the sound-activated switch, and the sound-activated switch is electrically connected to the sound alarm. The tactile sensor transmits an electrical signal indicating an abnormal reset to the controller. Upon feedback, the controller closes the sound-activated switch of the sound alarm, causing it to emit an audible warning, thus notifying the operators on site. By setting up the sound alarm, in the event of an abnormal reset, operators are effectively alerted to pay close attention to the sintering machine trolley passing the travel detection mechanism, providing secondary protection and preventing safety accidents.

[0010] Preferably, the controller is electrically connected to the main control display, and the main control display is electrically connected to the first motion capture camera, which is positioned above the elastic slide between the stroke detection mechanism and the reset execution mechanism. On-site operators can use the first motion capture camera to observe the elastic slide passing through the stroke detection mechanism in real time, thereby achieving real-time safety monitoring of the sintering machine trolley.

[0011] Preferably, the reset actuator includes an electro-hydraulic actuator. A signal interface on the electro-hydraulic actuator housing is electrically connected to the controller. The thrust rod of the electro-hydraulic actuator is disposed within a guide rail, and a reset rod is fixedly connected to the thrust rod, which is positioned above the elastic rail. Upon receiving a reset command from the controller, the electro-hydraulic actuator pushes the reset rod. Under the force of the reset rod, the sealing oil plate presses against the support spring, thereby achieving forced reset. By using an electro-hydraulic actuator, the controller's electrical signal can be quickly converted into an execution command, shortening the response time of the reset actuator and improving its execution efficiency. Furthermore, the guide rail ensures the stability of the reset actuator, further enhancing the overall system efficiency.

[0012] Preferably, a second motion capture camera is installed above the reset lever, and the second motion capture camera is electrically connected to the main control display. The second motion capture camera can display the real-time working status of the reset actuator on the main control display, which facilitates real-time monitoring of the reset actuator by the operator and further improves the overall system safety.

[0013] Preferably, the sintering machine trolley has wheels mounted on its base, which are placed on guide rails that are vertically positioned. The sintering machine trolley rotates in a circular motion on the guide rails. The sintering machine trolley begins feeding material at the leftmost end of the upper surface of the guide rails, and the sintering process is carried out as it moves from the leftmost end to the rightmost end of the upper surface of the guide rails. After the sintering machine trolley reaches the rightmost end of the upper surface of the guide rails, the sintering is completed and the sintered material is unloaded. Then, it moves back to the initial position via the lower position of the guide rails to process the next batch of sintered material.

[0014] Preferably, a fixed slide rail is provided on the inner side of the upper surface of the guide rail, and an elastic slide rail is provided above the fixed slide rail. Only an elastic slide rail is provided on the inner side of the lower surface of the guide rail. The upper surface of the guide rail is the surface where the sintering process is carried out. The fixed slide rail and the elastic slide rail together form a dynamic seal, which can prevent air leakage in the sintering negative pressure system, improve the efficiency of sintering production, control sintering energy consumption, and ensure the safety and stability of the sintering process.

[0015] On the other hand, the present invention also provides a method for detecting and resetting the travel of the elastic slide of a sintering machine trolley, comprising the following steps:

[0016] S1, the sintering machine trolley starts running from point A and rotates clockwise along the guide rail. When the sintering machine trolley runs on the upper surface of the guide rail, the elastic slide forms a dynamic seal with the fixed slide through the sealing oil plate.

[0017] S2, after the sintering machine trolley reaches point B, the sintering machine trolley will no longer move along the fixed slide.

[0018] S3, when the elastic slide passes over the travel detection mechanism, if the sealing oil plate cannot automatically reset, the sealing oil plate will push the detection wheel, the detection wheel will drive the transmission rod to rotate, and the other end of the transmission rod, which is fixedly connected to the detection wheel, will press the sensor, and the controller will receive the electrical signal that it cannot be reset;

[0019] S4. After receiving the electrical signal, the controller closes the sound-activated switch, causing the sound alarm to emit an audible alarm and displaying the alarm information on the main control display.

[0020] S5, the controller controls the electro-hydraulic actuator, which pushes the reset rod, and the reset rod presses the elastic slide, forcing the elastic slide to reset.

[0021] Preferably, the main control display in S4 can display real-time images of the elastic slide captured by the first motion capture camera and the second motion capture camera.

[0022] As can be seen from the above technical solutions, the present invention has the following advantages:

[0023] 1. The stroke detection mechanism of this invention can detect the resetting status of the sealing oil plate in real time and transmit the resetting status to the controller. If the sealing oil plate cannot be reset normally, the controller will control the actuator to force the sealing oil plate to reset and transmit the resetting status of the sealing oil plate to the main control display in real time, providing timely feedback to the on-site operators. This invention, by using the stroke detection mechanism and the reset actuator, can automatically detect the working status of the elastic slide and accurately reset abnormal elastic slides, effectively avoiding accidents caused by the breakage of the fixed slide due to abnormal elastic slides, greatly improving the stability of the sintering machine trolley operation, and further ensuring production efficiency.

[0024] 2. This invention has a simple configuration and flexible structure. It can be installed at the location that needs to be detected according to the size and distribution of the sintering machine trolley. It is convenient, quick, easy to disassemble and assemble, has a stable structure, is reusable, and has strong versatility.

[0025] 3. By setting up a second motion capture camera and a first motion capture camera, the present invention facilitates operators to observe the working status of the sintering machine trolley in a timely manner, providing secondary protection and effectively preventing safety accidents.

[0026] 4. This invention uses a fixed slide and an elastic slide to form a dynamic seal, which can prevent air leakage in the sintering negative pressure system, improve the efficiency of sintering production, control sintering energy consumption, and ensure the safety and stability of the sintering process.

[0027] Furthermore, the design principle of this invention is reliable, it can be installed quickly, and it has a very wide range of application prospects. Attached Figure Description

[0036] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0037] Please see the appendix Figure 1-6This specific embodiment provides a sintering machine trolley elastic slide travel detection and reset system, including a sintering machine trolley 18. The base of the sintering machine trolley 18 is fixed together with an elastic slide 4. The elastic slide 4 is connected to a sealing oil plate 2 through a support spring 3. A travel detection mechanism is provided above the sealing oil plate 2. The travel detection mechanism is electrically connected to a controller 11. The controller 11 is electrically connected to a main control display 12 and a reset actuator. The elastic slide travel detection and reset system is installed at point C. The travel detection mechanism can detect the reset status of the sealing oil plate 2 in real time and transmit the reset status of the sealing oil plate 2 to the controller 11. If the sealing oil plate 2 cannot be reset normally, the controller 11 will control the actuator to force the sealing oil plate 2 to reset and transmit the reset status of the sealing oil plate 2 to the main control display 12 in real time for timely feedback to the on-site operators. This invention can automatically detect the working status of the elastic slide 4 by using a stroke detection mechanism and a reset execution mechanism, and accurately reset the elastic slide 4 if there is any abnormality. This can effectively avoid the accident of the fixed slide 1 breaking due to the abnormal state of the elastic slide 4, greatly improve the stability of the sintering machine trolley 18, and further ensure production efficiency.

[0038] The stroke detection mechanism includes a probe wheel 5, which is connected to one end of a transmission rod 6. A rotating shaft 7 is installed in the middle of the transmission rod 6, and touch sensors 8 are installed on both sides of the other end of the transmission rod 6. The touch sensors 8 are electrically connected to the controller 11. When the sealing oil plate 2 abnormally resets, one or both ends of the sealing oil plate 2 will be higher than the normal reset height, causing the sealing oil plate 2 to push the probe wheel. The probe wheel 2 drives the transmission rod 6 to rotate along the rotating shaft 7 in the middle, causing the transmission rod 6 to press the touch sensor 8, thereby generating an abnormal reset electrical signal. The stroke detection mechanism has a simple structure, flexible configuration, and high reliability, and can be applied to various harsh working environments, thus ensuring accurate detection of the elastic slide 4. Furthermore, the stroke detection mechanism has high sensitivity, which can improve the overall system's responsiveness to abnormal resets. The touch sensor 8 is electrically connected to the controller 11, the controller 11 is electrically connected to the sound-activated switch 10, and the sound-activated switch 10 is electrically connected to the sound alarm 9. The touch sensor 8 has contacts on both sides of the transmission rod 6, triggering it regardless of whether the transmission rod 6 deflects to the left or right. The touch sensor 8 transmits an electrical signal indicating an abnormal reset to the controller 11. Simultaneously, the controller 11 closes the sound-activated switch 10 of the sound alarm 9, causing it to emit an audible warning to notify the operators. By installing the sound alarm 9, in the event of an abnormal reset, operators are effectively alerted to pay close attention to the sintering machine trolley 18 passing the stroke detection mechanism, providing secondary protection and preventing accidents.

[0039] The controller 11 is electrically connected to the main control display 12, and the main control display 12 is electrically connected to the first motion capture camera 17, which is positioned above the elastic slide 4 between the stroke detection mechanism and the reset execution mechanism. On-site operators can observe the elastic slide 4 passing through the stroke detection mechanism in real time through the first motion capture camera 17, thereby achieving real-time safety monitoring of the sintering machine trolley 18.

[0040] The reset actuator includes an electro-hydraulic actuator 13, whose thrust rod is located within a guide slide 14. A reset rod 15 is fixedly connected to the thrust rod of the electro-hydraulic actuator 13 and is positioned above the elastic slide 4. Upon receiving a reset command from the controller 11, the electro-hydraulic actuator 13 pushes the reset rod 15. Under the force of the reset rod 15, the sealing oil plate 2 presses against the support spring 3, thereby achieving forced reset. By using the electro-hydraulic actuator 13, the electrical signal from the controller 11 can be quickly converted into an execution command, shortening the reaction time of the reset actuator and improving its execution efficiency. Furthermore, the guide slide 14 ensures the stability of the reset actuator, further enhancing the overall system efficiency. A second motion capture camera 16 is positioned above the reset rod 15 and is electrically connected to the main control display 12. The second motion capture camera 16 displays the real-time operating status of the reset actuator on the main control display 12, facilitating real-time monitoring by operators and further improving the overall system safety.

[0041] The sintering machine trolley 18 has wheels 19 mounted on its base, which rest on guide rails 20, which are vertically positioned. The sintering machine trolley 18 rotates in a circular motion on the guide rails 20. The trolley 18 begins feeding material at the leftmost end of the upper surface of the guide rails 20, and performs the sintering process as it moves from the leftmost to the rightmost end. After reaching the rightmost end of the upper surface of the guide rails 20, sintering is completed, and the sintered material is unloaded. It then moves back to its initial position via the lower surface of the guide rails 20 to process the next batch of sintered material. A fixed slide rail 1 is provided on the inner side of the upper surface of the guide rails 20, and an elastic slide rail 4 is provided above the fixed slide rail 1. Only the elastic slide rail 4 is provided on the inner side of the lower surface of the guide rails 20. The upper surface of the guide rail 20 is the surface where the sintering process is carried out. The fixed slide 1 and the elastic slide 4 together form a dynamic seal, which can prevent air leakage in the sintering negative pressure system, improve the efficiency of sintering production, control sintering energy consumption, and ensure the safety and stability of the sintering process.

[0042] The foregoing has described in detail an embodiment of a sintering machine trolley elastic slide travel detection and reset system.

When the sintering machine trolley 18 is running on the upper surface of the guide rail 20, the elastic slide 4 forms a dynamic seal with the fixed slide 1 through the sealing oil plate 2. When the sintering machine trolley 18 is running on the upper surface of the guide rail 20, it is also the process of sintering the ore inside the sintering machine trolley 18. During this period, it is necessary to ensure the dynamic sealing state of the fixed slide 1 and the elastic slide 4, otherwise the sintering efficiency will be affected.

[0044] S2, after the sintering machine trolley 18 reaches point B, the sintering machine trolley 18 will no longer move along the fixed slide 1; after the sintering machine trolley 18 leaves the fixed slide on the upper surface of the guide rail 20, the support spring 3 between the elastic slide 4 and the sealing oil plate 2 will return from the compressed state to the free state.

[0045] S3, when the elastic slide 4 passes over the travel detection mechanism, if the sealing oil plate 2 cannot automatically reset, the sealing oil plate 2 will push the detection wheel 5, the detection wheel 5 will drive the transmission rod 6 to rotate, and the other end of the transmission rod 6, which is fixedly connected to the detection wheel 5, will press the touch sensor 8, and the controller 11 will receive the electrical signal that it cannot be reset.

[0046] S4, after receiving the electrical signal, the controller 11 closes the sound control switch 10, causing the sound alarm 9 to emit a sound alarm and display the alarm information on the main control display 12.

[0047] S5, the controller 11 controls the electro-hydraulic push rod 13, causing the electro-hydraulic push rod 13 to push the reset rod 15, and the reset rod 15 presses the elastic slide 4, causing the elastic slide 4 to be forcibly reset.

[0048] In particular, the main control display 12 in S4 can display real-time images of the elastic slide 4 captured by the first motion capture camera 17 and the second motion capture camera 16.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
