The insulating clamping ring and the clamping blocks are staggered and slidably connected to the clamping blocks.

[0020] Beneficial effects of the present invention:

[0021] (1) During operation, the first distance meter and the first identification plate are used to monitor the positioning of the flame blast furnace, the second distance meter and the second identification plate are used to monitor the positioning of the tail frame, and the third distance meter and the transmission rod are used to monitor the positioning of the sintering trolley. Through uninterrupted monitoring, one or several faulty sintering trolleys are prevented from moving the flame blast furnace or the tail frame during the sintering process, and the flame blast furnace or the tail frame is prevented from being displaced due to the sintering trolley scraping against the flame blast furnace or the tail frame. The first distance meter, which is symmetrical with respect to the first identification plate, is used to monitor the displacement distance and displacement direction of the flame blast furnace in two directions, thereby accurately obtaining the displacement of the flame blast furnace during the sintering process, and facilitating further classification and research of the displacement cause. Similarly, the displacement direction and displacement distance of the tail frame are monitored uninterruptedly, and the movement of the sintering trolley during the carrying and transportation process is monitored uninterruptedly by the third distance meter and the transmission rod. Auxiliary support is provided by the side support bracket, and the support slide is used to provide auxiliary support. The frame maintains the stable movement of the transmission rod. When the sintering trolley is misaligned or the trolley railing on it is tilted and tilted, the transmission rod at this position moves different distances toward the third distance meter according to the magnitude of the force and the action distance. The third distance meter sends different signals according to the monitored movement distances of the transmission rod. The transmission rod is protected by the abutment roller to avoid overheating of the transmission rod due to contact with the sintering trolley, and the resistance of the transmission rod during sensing is reduced, thereby improving the sensitivity of the transmission rod. The side wall of the sintering trolley is determined to a standard position by the abutment guide rail, and the resistance during sensing by the abutment roller is reduced, thereby improving the accuracy of sensing. The fault can be discovered in time and the position of the fault can be quickly determined according to the positions of the first distance meter, the second distance meter and the third distance meter, so as to facilitate rapid disposal by maintenance personnel, reduce losses and improve efficiency. The displacement data during operation and maintenance can also be accurately collected, which is convenient for attribution summary and further improvement, thereby further reducing the failure rate and improving production efficiency.

[0022] (2) During operation, the fault location is determined by the on and off of different indicator lights. At the same time, the displacement direction of the flamethrower and the tail swing frame is determined by the on and off of different corresponding indicator lights, so that it is convenient to carry different maintenance equipment for different fault causes and improve work efficiency. The first rangefinder, the second rangefinder and the third rangefinder are all connected in parallel to the same main circuit. After startup, each switch assembly exposes its own part in different areas respectively, and the projections of each area on the side wall of the installation box are coaxial and connected end to end and are of the same length as the switch assembly. The indicator lights of this embodiment use green, yellow and red to represent the three conditions of normal, warning and fault respectively. Under the elastic force of the reset spring, the positioning slide is stationary on one side of the installation box at the initial position, and the positioning rod extends out of the installation box. At this time, the switch assembly that is connected corresponds to the green light, and the entire circuit is connected, and the green light is always on to indicate that the working process is normal. When a fault occurs, for example, when the flamethrower shifts, the positioning rod on the first rangefinder is pushed by the first identification plate to retract into the installation box, pushing the positioning slide to slide, and electrically connected to the green indicator light. The connected switch assembly gradually stops contacting with the conductive slider connected to the corresponding one, and the conductive slider connected to the yellow indicator light gradually abuts against the switch assembly corresponding to it, thereby electrically connecting. At this time, the yellow indicator light at the corresponding position lights up, which is convenient for reminding the staff. When the flame-blowing furnace continues to move, the yellow light goes out and the red light lights up, thereby notifying the staff that there is a fault in the corresponding area, thereby notifying the workers of the occurrence of the fault in a timely manner and indicating the area of ​​the fault. At the same time, the yellow light can be used to allow the staff to prepare the corresponding tools in advance, which is convenient for rapid dispatch after the yellow light turns red, thereby improving the efficiency of each dispatch. The ranging probe and the ranging reflector cooperate with each other to further accurately detect the moving distance of the positioning slide, thereby obtaining more accurate data when working at each position, so that the staff can make further optimization. At the same time, the low-temperature refrigerant is connected through the refrigerant pipe to maintain the temperature of the installation box, and the various connections of the installation box can be easily sealed and isolated, thereby protecting the ranging probe and ranging reflector, so that it can work stably and effectively in a high temperature, high dust and high pollution environment.

[0023] (3) When working, the conductive slide groove faces upward and is opposite to the conductive slider. The conductive slider corresponds to a series of indicator lights of one color. The corresponding three switch components are set as a group. The connection area of ​​each switch component is set according to different needs. The connection area of ​​the switch component with the green light in series is closest to the positioning rod, and the connection areas of the switch components with the yellow and red lights in series are farther away in sequence. When setting the connection area, rotate the insulating clamp on the conductive slider so that the gap of the insulating clamp is opposite to the conductive slide groove, so that the conductive slider can pass through the gap of the insulating clamp and abut against the conductive slide groove to connect the circuit. According to the length and position of the connection area, rotate different areas and different numbers of insulating clamps. Ring, so as to quickly and accurately set the distances corresponding to normal, warning and fault, and at the same time be able to flexibly adjust the length of the corresponding distance according to different needs, and each of the first rangefinder, the second rangefinder and the third rangefinder will not be affected by the high temperature, high dust and high pollution environment during operation, and can achieve almost no faults and can work for a long time, with stable line connections, and can accurately display the location and severity of the fault. The added groups of indicator lights reflect different working conditions at different positions, fully covering the main positions of the main components, and displaying the working status one group at a time, so as to fully record the working data and assist in optimization work.

Through uninterrupted monitoring, one or several malfunctioning sintering trolleys 103 are prevented from moving the flammable furnace 101 or the tail swing frame 102 during the sintering process, and the displacement of the flammable furnace 101 or the tail swing frame 102 caused by the sintering trolley 103 scraping against the flammable furnace 101 or the tail swing frame 102 is avoided. The displacement distance of the flammable furnace 101 in two directions and the displacement distance of the flammable furnace 101 in two directions are monitored by the first rangefinder 205 which is symmetrical with respect to the first identification plate 208. The displacement direction is continuously monitored, so as to accurately obtain the displacement of the flame-spraying furnace 101 during the sintering process, which is convenient for further classification and research of the reasons for its displacement.

[0034] The third bracket 203 is provided with a side support bracket 204 on the side close to the sintering trolley 103, and a support slide 214 is provided on the side support bracket 204. The transmission rod 212 is slidably connected to the support slide 214. The transmission rod 212 is provided with an abutting roller 213 on one end close to the sintering trolley 103. The side of the sintering trolley 103 is provided with an abutting guide rail 215 near the transmission rod 212. The abutting roller 213 is in rolling connection with the abutting guide rail 215. When working, the side support bracket 204 is used for auxiliary support, and the support slide 214 is used to keep the transmission rod 212 in stable movement. When the sintering trolley 103 is dislocated or the trolley on it is offset, When the railing tilts and falls, the transmission rod 212 at this position moves different distances toward the third rangefinder 207 according to the magnitude of the force it receives and the distance of action. The third rangefinder 207 sends different signals according to the monitored movement distances of the transmission rod 212. The transmission rod 212 is protected by the abutment roller 213 to prevent the transmission rod 212 from overheating due to contact with the sintering trolley 103, and the resistance of the transmission rod 212 during sensing is reduced, thereby improving the sensitivity of the transmission rod 212. The side wall of the sintering trolley 103 is determined in a standard position by the abutment guide rail 215, and the resistance of the abutment roller 213 during sensing is reduced, thereby improving the accuracy of sensing.

[0035] The first rangefinder 205, the second rangefinder 206 and the third rangefinder 207 are respectively connected in series with indicator lights, and the indicator lights corresponding to the first rangefinder 205, the second rangefinder 206 and the third rangefinder 207 are all concentrated on a display board. During operation, the fault location is determined by the on and off of different indicator lights. At the same time, the shifting direction of the flame furnace 101 and the tail swing frame 102 is determined by the on and off of different corresponding indicator lights, so that it is convenient to carry different maintenance equipment according to different fault causes, thereby improving work efficiency.

[0036] The first rangefinder 205, the second rangefinder 206, and the third rangefinder 207 each include a mounting box 301. A positioning slide 302 is slidably connected to the middle portion of the inner side of the mounting box 301. A positioning rod 303 is provided on one side of the mounting box 301. One end of the positioning rod 303 is slidably connected to the mounting box 301 and fixedly connected to one side of the positioning slide 302. The other end of the positioning rod 303 is fixedly connected to the transmission rod 212, and the positioning rod 303 and the transmission rod 212 are coaxial. A return spring 304 is installed on the other side of the positioning slide 302.

[0037] A switch assembly 305 is provided in the middle of the inner side of the mounting box 301 and directly below the positioning slide 302. There are three switch assemblies 305, and each switch assembly 305 is electrically connected to a power supply and an indicator light of a different color. A spring rod 406 is installed on the lower side of the middle of the positioning slide 302. The spring rod 406 corresponds to the switch assembly 305 one-to-one. A conductive slider 405 is installed at the lower end of the spring rod 406, and the conductive slider 405 is electrically connected to the switch assembly 305.

[0038] A distance measuring probe 306 is installed on the inner side wall of the installation box 301 away from the positioning slide 302. A distance measuring reflector 307 is embedded on the side wall of the positioning slide 302 corresponding to the distance measuring probe 306. Refrigerant pipes 308 are embedded in the two side walls of the installation box 301.

[0039] When the present embodiment is working, each of the first rangefinder 205, the second rangefinder 206 and the third rangefinder 207 are connected in parallel to the same main circuit. After startup, each switch assembly 305 exposes its own part in different areas respectively, and the projections of each area on the side wall of the installation box 301 are coaxial and connected end to end and are of the same length as the switch assembly 305. The indicator lights of the present embodiment use green, yellow and red to represent normal, warning and fault conditions respectively. Under the elastic force of the reset spring 304, the positioning slide 302 is stationary on one side of the installation box 301 at the initial position, and the positioning rod 303 extends out of the installation box 301. At this time, the connected switch assembly 305 is connected to the green light, and the entire circuit is connected, and the green light is always on to indicate that the working process is normal. When a fault occurs, for example, when the flame furnace 101 is displaced, the first rangefinder 20 5 is pushed by the connected first identification plate 208 and retracted into the installation box 301, pushing the positioning slide 302 to slide, and the switch component 305 electrically connected to the green indicator light gradually stops contacting with the conductive slider 405 connected to it, and the conductive slider 405 connected to the yellow indicator light gradually abuts against the switch component 305 corresponding to it to be electrically connected. At this time, the yellow indicator light at the corresponding position lights up, which is convenient for the staff to remind attention. When the flame furnace 101 continues to shift, the yellow light goes out and the red light lights up, thereby notifying the staff that there is a fault in the corresponding area, thereby notifying the staff of the occurrence of the fault in a timely manner and indicating the area of ​​the fault. At the same time, the yellow light can be used to allow the staff to prepare the corresponding tools in advance, facilitate rapid dispatch after the yellow light turns red, and improve the efficiency of each dispatch.

[0040] The switch assembly 305 includes a conductive slide rod 401, both ends of which are fixedly connected to the installation box 301. A conductive slide groove 402 is provided on one side of the outer periphery of the conductive slide rod 401, and the conductive slider 405 is slidably connected to the conductive slide groove 402. The outer periphery of the conductive slide rod 401 and both sides of the conductive slide groove 402 are fixedly connected with a clamping block 403. Each side has a plurality of clamping blocks 403 that are evenly distributed at equal intervals. An insulating clamping ring 404 is slidably sleeved on the conductive slide rod 401. One side of the insulating clamping ring 404 is vacant, and the vacant arc length of the insulating clamping ring 404 is consistent with the width of the conductive slide groove 402. The insulating clamping ring 404 and the clamping block 403 are staggered and slidably connected to the clamping block 403.

[0041] When working, the conductive chute 402 faces upward and is opposite to the conductive slider 405. The conductive slide rod 401 corresponds to an indicator light of one color connected in series. This embodiment is provided with indicator lights of three colors. Therefore, the corresponding three switch components 305 are set as a group. The connection area of ​​each switch component 305 is set according to different needs. The connection area of ​​the switch component 305 of the series green light is closest to the positioning rod 303, and the connection areas of the switch components 305 of the series yellow light and red light are farther away in sequence. When setting the connection area, the insulating clamp 404 is rotated on the conductive slide rod 401 so that the vacant part of the insulating clamp 404 is opposite to the conductive chute 402, so that the conductive slider 405 can pass through the insulating The vacant part of the clamping ring 404 abuts against the conductive slide groove 402 to connect the circuit. Different areas and different numbers of insulating clamping rings 404 are rotated according to the length and position of the connected area, so as to quickly and accurately set the distances corresponding to normal, warning and fault conditions. At the same time, the length of the corresponding distance can be flexibly adjusted according to different needs. In addition, each of the first rangefinder 205, the second rangefinder 206 and the third rangefinder 207 is not affected by high temperature, high dust and high pollution environments during operation. It can achieve almost no faults and can work for a long time with stable line connection. At the same time, it can accurately display the location and severity of the fault, thereby improving overall work efficiency.

[0042] During operation, the ranging probe 306 and the ranging reflector 307 cooperate with each other to further accurately detect the moving distance of the positioning slide 302, thereby obtaining more accurate data when working at each position, so that the staff can make further optimization. At the same time, the low-temperature refrigerant is connected through the refrigerant pipe 308 to maintain the temperature of the installation box 301, and each connection of the installation box 301 can be easily sealed and isolated, thereby protecting the ranging probe 306 and the ranging reflector 307, so that they can work stably and effectively in a high-temperature, high-dust and high-pollution environment.

[0043] When the present invention is in use, the staff uses the first rangefinder 205 and the first identification plate 208 to monitor the positioning of the flame-spraying furnace 101, uses the second rangefinder 206 and the second identification plate 210 to monitor the positioning of the tail swing frame 102, and uses the third rangefinder 207 and the transmission rod 212 to monitor the positioning of the sintering trolley 103. Through uninterrupted monitoring, it is possible to prevent one or more faulty sintering trolleys 103 from moving the flame-spraying furnace 101 or the tail swing frame 102 during the sintering process, thereby avoiding the sintering trolley 103 from scraping the flame-spraying furnace 101 or the tail swing frame 102. The flaming furnace 101 or the tail swing frame 102 is displaced. The first distance meter 205 symmetrical to the first identification plate 208 is used to continuously monitor the displacement distance and displacement direction of the flaming furnace 101 in two directions, thereby accurately obtaining the displacement of the flaming furnace 101 during the sintering process, which is convenient for further classification and research on the reasons for its displacement. Similarly, the displacement direction and displacement distance of the tail swing frame 102 are continuously monitored, and the movement of the sintering trolley 103 during the carrying and transportation process is continuously monitored by the third distance meter 207 and the transmission rod 212. 4 provides auxiliary support and maintains the stable movement of the transmission rod 212 through the support slide 214. When the sintering trolley 103 is misaligned or the trolley railing on it is tilted and tilted, the transmission rod 212 at this position moves different distances toward the third rangefinder 207 according to the magnitude of the force and the distance of action. The third rangefinder 207 sends different signals according to the different movement distances of the transmission rod 212 monitored. The transmission rod 212 is protected by the abutting roller 213 to prevent the transmission rod 212 from contacting the sintering trolley 103 and overheating, and to reduce the resistance of the transmission rod 212 during sensing. The sensitivity of the transmission rod 212 is improved, and the side wall of the sintering trolley 103 is determined to be in a standard position by the abutment guide rail 215. The resistance during the abutment roller 213 sensing is reduced, thereby improving the accuracy of the sensing. Faults can be discovered in a timely manner and the location of the fault can be quickly determined based on the positions of the first distance meter 205, the second distance meter 206, and the third distance meter 207, so that maintenance personnel can quickly handle the fault, reduce losses, and improve efficiency. In addition, displacement data during operation and maintenance can be accurately collected, which facilitates attribution summary and further improvement, thereby further reducing the failure rate and improving production efficiency.

[0044] During operation, the fault location is determined by the on and off of different indicator lights. At the same time, the shifting direction of the flame furnace 101 and the tail swing frame 102 is determined by the on and off of different corresponding indicator lights, so that it is convenient to carry different maintenance equipment according to different fault causes and improve work efficiency. The first rangefinder 205, the second rangefinder 206 and the third rangefinder 207 are all connected in parallel to the same main circuit. After startup, each switch assembly 305 exposes its own part in different areas, and the projections of each area on the side wall of the installation box 301 are coaxial and connected end to end and have the same length as the switch assembly 305. The indicator of this embodiment is The indicator lights use green, yellow and red to represent three situations: normal, caution and fault. Under the elastic force of the reset spring 304, the positioning slide 302 is stationary on one side of the installation box 301 at the initial position, and the positioning rod 303 extends out of the installation box 301. At this time, the switch component 305 that is turned on is connected to the green light, and the entire circuit is connected, and the green light is always on to indicate that the working process is normal. When a fault occurs, for example, when the flame furnace 101 shifts, the positioning rod 303 on the first rangefinder 205 is pushed by the connected first identification plate 208 and retracts into the installation box 301, pushing the positioning slide 302 to slide , the switch component 305 electrically connected to the green indicator light gradually stops contacting with the conductive slider 405 connected to it, and the conductive slider 405 connected to the yellow indicator light gradually abuts against the switch component 305 corresponding to it, thereby electrically connecting. At this time, the yellow indicator light at the corresponding position lights up, which is convenient for the staff to remind them to pay attention. When the flame furnace 101 continues to move, the yellow light goes out and the red light lights up, thereby notifying the staff that there is a fault in the corresponding area, thereby notifying the staff of the occurrence of the fault in a timely manner, and indicating the area of ​​the fault. At the same time, the yellow light can be used to let the staff prepare the corresponding tools in advance. In order to facilitate rapid dispatch after the yellow light turns red and improve the efficiency of each dispatch, the ranging probe 306 and the ranging reflector 307 cooperate with each other to further accurately detect the moving distance of the positioning slide 302, thereby obtaining more accurate data when working at each position, so that the staff can make further optimization. At the same time, low-temperature refrigerant is connected through the refrigerant pipe 308 to maintain the temperature of the installation box 301, and each connection of the installation box 301 can be easily sealed and isolated, thereby protecting the ranging probe 306 and the ranging reflector 307, so that they can work stably and effectively in a high-temperature, high-dust and high-pollution environment;

[0045] When working, the conductive slide 402 faces upward and is opposite to the conductive slider 405. The conductive slide rod 401 corresponds to a color indicator light in series. The corresponding three switch components 305 are set as a group. The connection area of ​​each switch component 305 is set according to different needs. The connection area of ​​the switch component 305 of the series green light is closest to the positioning rod 303, and the connection areas of the switch components 305 of the series yellow and red lights are farther away in sequence. When setting the connection area, rotate the insulating clamp 404 on the conductive slide rod 401 so that the vacant part of the insulating clamp 404 is opposite to the conductive slide 402, so that the conductive slider 405 can pass through the vacant part of the insulating clamp 404 and abut against the conductive slide 402 to connect the circuit. By rotating the insulating clips 404 in different areas and numbers, the distances corresponding to normal, caution and fault can be set quickly and accurately. At the same time, the length of the corresponding distance can be flexibly adjusted according to different needs. In addition, each of the first rangefinder 205, the second rangefinder 206 and the third rangefinder 207 is not affected by the high temperature, high dust and high pollution environment during operation. It can be almost fault-free and can work for a long time. The line connection is stable. At the same time, it can accurately display the location of the fault and the severity of the situation. The different working conditions at different positions are reflected by the added groups of indicator lights, which fully cover the main positions of the main components and display the working status one group at a time, so as to fully record the working data and assist in optimizing the work.
