Description

Technical Field

[0001] The present invention relates to the technical field of metallurgy, and in particular to a side seal safety protection system and protection method for a sintering machine. Background Art

[0002] A sintering machine is one of the important equipment in the sintering production process in the metallurgical field. When the sintering machine trolley moves linearly along the plane guide rail, the elastic slide plate assembly is in contact with the fixed slideway at all times under the elastic force of the internal support spring, thereby forming a dynamic seal to prevent air leakage in the sintering negative pressure system and avoid a rapid increase in energy consumption.

[0003] Since the elastic slide plate assembly is in a high-temperature and multi-dust working condition, it is prone to fatigue deformation or caking and siltation after long-term operation, resulting in the inability of the elastic slide plate assembly to automatically complete reset, and thus it will rub against the fixed slideway. Currently, in order to avoid the breakage and damage of the fixed slideway and the shutdown of the entire material line, there has emerged a travel detection and reset system and method for the elastic slideway of a sintering machine trolley (publication number CN116222219A), which installs the travel detection and reset system as a whole at the position where the sintering trolley separates from the fixed slideway for detecting and assisting the reset of the elastic slide plate.

[0004] The existing travel detection and reset system for the elastic slideway of a sintering machine trolley cannot effectively limit the elastic slide plate before it contacts the fixed slideway. When the trolley moves, after the elastic slide plate separates from the travel detection and reset system, the elastic slide plate that has lost its self-resetting ability will still rub against and collide with the fixed slideway, and it cannot clean the dust adhered to the surface of the elastic slide plate's floating plate, affecting the sealing effect and prone to air leakage. Summary of the Invention

[0005] To solve the technical problem in the above background art that the existing travel detection and reset system for the elastic slideway of a sintering machine trolley cannot effectively limit the elastic slide plate before it contacts the fixed slideway, and the elastic slide plate that has lost its self-resetting ability will still rub against and collide with the fixed slideway, the present invention provides a side seal safety protection system for a sintering machine.

[0006] The technical solution of the present invention is as follows: The present invention provides a safety protection system for side seals of a sintering machine, which includes a trolley and an elastic slide plate assembly detachably installed on the trolley. It also includes a fixed slideway assembly fixedly installed on the sintering machine frame. A limit detection unit and a reset mechanism are provided on the head side of the fixed slideway assembly. The reset mechanism is close to the fixed slideway assembly. Both the limit detection unit and the reset mechanism are connected to a control mechanism. The limit detection unit and the reset mechanism are located below the elastic slide plate assembly. The limit detection unit is used to detect whether the elastic slide plate assembly automatically resets, and the reset mechanism is used to assist in pushing the elastic slide plate assembly to reset. It can timely detect the situation where the elastic slide plate assembly does not automatically reset and perform auxiliary reset, ensuring the normal operation of the elastic slide plate assembly, guaranteeing the stable operation of the sintering machine system, avoiding collisions between the elastic slide plate assembly and the fixed slideway assembly when the elastic slide plate assembly does not automatically reset, preventing damage to the elastic slide plate assembly and the fixed slideway assembly, and reducing the risk of shutdown.

[0007] Preferably, the distance between the reset mechanism and the head side of the fixed slideway assembly is the same as half of the length dimension of the elastic slide plate assembly, which can enable the reset mechanism to push the middle area of the bottom of the elastic slide plate assembly, ensuring the best effect of the reset force, improving the accuracy and efficiency of reset, facilitating the stable and rapid restoration of the elastic slide plate assembly to the normal position, and at the same time ensuring uniform stress on both ends of the elastic slide plate assembly, avoiding skewed stress on one end of the elastic slide plate assembly close to the fixed slideway assembly, and effectively preventing collision damage between the elastic slide plate assembly and the fixed slideway assembly.

[0008] Preferably, the reset mechanism includes a bracket fixedly arranged on the sintering machine frame. An installation frame is slidably arranged on the bracket. The installation frame is vertically arranged. A roller is rotatably arranged at the top of the installation frame. The bracket and the installation frame are connected by a linear drive assembly. A limit switch is installed on the bracket. The linear drive assembly can control the position of the roller to use the roller to push the elastic slide plate assembly. The setting of the roller can reduce the friction when contacting the elastic slide plate assembly and avoid damaging the elastic slide plate assembly.

[0009] Preferably, a cleaning mechanism and a purging mechanism are provided on the head side of the fixed slideway assembly. Both the cleaning mechanism and the purging mechanism are connected to the control mechanism. Both the cleaning mechanism and the purging mechanism are located below the elastic slide plate assembly. The cleaning mechanism and the purging mechanism can timely remove dust and other debris below the elastic slide plate assembly, prevent their accumulation from affecting the normal cooperation between the elastic slide plate assembly and the fixed slideway assembly, extend the service life of the equipment, ensure the smooth operation of the elastic slide plate assembly, and improve the working efficiency of the sintering machine system.

[0010] Preferably, the cleaning mechanism includes connecting rods rotatably connected to the sintering machine frame. There are two connecting rods, and a cleaning brush is rotatably arranged between the two connecting rods. A first driving motor for driving the cleaning brush is installed on the connecting rod. The lower surface of the connecting rod is hinged to the sintering machine frame through a support rod, and the support rod and the connecting rod are fixedly connected through a second spring. The first driving motor can drive the cleaning brush to rotate at a high speed, effectively cleaning the dust on the elastic slide plate assembly. The setting of the second spring can ensure the flexible contact between the cleaning brush and the surface of the elastic slide plate assembly, preventing damage to the elastic slide plate assembly and the cleaning brush.

[0011] Preferably, the fixed slideway assembly includes a first fixed slideway, a second fixed slideway, a third fixed slideway, and a fourth fixed slideway with a bimetal inlaid composite structure. The bimetal inlaid composite structure can improve the wear resistance, sealing performance, etc. of the fixed slideway, and has a long service life. The first fixed slideway is located on the head side, and the fourth fixed slideway is located on the tail side. An anti-lifting structure is fixedly arranged at one end of the first fixed slideway close to the reset mechanism. The bottom of the anti-lifting structure is fixedly connected to the sintering machine frame through an obliquely arranged reinforcing rod. The anti-lifting structure can prevent the elastic slide plate assembly from being lifted and damaged due to jamming with the fixed slideway assembly during operation, ensuring the safety of equipment operation. The reinforcing rod further strengthens the stability and firmness of the anti-lifting structure.

[0012] Preferably, a dust-proof cover is fixedly installed on the lower plane of the sintering machine. The dust-proof cover can shield and protect the elastic slide plate assembly, preventing the ash material in the sintering machine system from falling onto the surface of the elastic slide plate assembly and into the assembly gap of the elastic slide plate, improving the cleanliness of the surface of the elastic slide plate assembly and facilitating the subsequent cleaning operation of the elastic slide plate assembly.

[0013] Preferably, it further includes a car number photographing unit, an alarm unit, a display unit, and a slide plate photographing unit connected to the control mechanism. The car number photographing unit is convenient for recording the trolley number where problems occur, facilitating subsequent traceability and management. The alarm unit can timely remind the operator that the equipment has a fault so that measures can be taken quickly. The display unit can visually display information such as the operating state of the equipment. The control mechanism stores a standard image of the slide plate and is used for photographing and comparison, and can accurately judge whether the elastic slide plate assembly is damaged, providing a basis for equipment maintenance.

[0014] The present invention provides a protection method, which is as follows: The elastic skateboard assembly travels along an elliptical track following the trolley. When the limit detection unit detects that the elastic skateboard assembly is not self-reset in place, the control mechanism controls the vehicle number photographing unit to photograph and record the trolley number; at the same time, the control reset mechanism performs a contact reset on the elastic skateboard assembly. The elastic skateboard assembly stably passes over the rear fixed slideway assembly in sequence, which can timely handle the situation where the elastic skateboard assembly is not reset. By recording the trolley number, it is convenient to analyze problems later. The contact reset ensures that the elastic skateboard assembly returns to its normal position, ensuring that it can stably pass over the subsequent fixed slideway assembly, avoiding collision damage between the elastic skateboard assembly and the fixed slideway assembly, and effectively maintaining the continuous operation of the sintering machine system.

[0015] Preferably, when the elastic skateboard assembly runs to the upper plane of the sintering machine, the cleaning mechanism and the purging mechanism clean and blow the dust on the elastic skateboard assembly. Then, it is photographed and compared by the skateboard photographing unit. When the elastic skateboard assembly is damaged, the vehicle number is recorded, an alarm is given, and the machine is stopped for maintenance at an opportune time. The damage of the elastic skateboard assembly can be detected in time. Recording the vehicle number is convenient for tracing the source of the problem. Alarm and stopping the machine for maintenance at an opportune time can prevent the equipment from continuing to operate in a damaged state and prevent more serious damage, ensuring the safe and stable operation of the sintering machine system.

[0016] It can be seen from the above technical solutions that the advantages of the present invention are as follows: 1. A limit detection unit and a reset mechanism are provided on the head side of the fixed slideway assembly. The limit detection unit is used to detect whether the elastic skateboard assembly is automatically reset, and the reset mechanism is used to assist in pushing the elastic skateboard assembly to reset. It can timely detect the situation where the elastic skateboard assembly is not automatically reset and perform auxiliary reset, ensuring that the elastic skateboard assembly can normally move above the fixed slideway assembly and cooperate with it, ensuring the stable operation of the sintering machine system, avoiding collision between the elastic skateboard assembly and the fixed slideway assembly when the elastic skateboard assembly is not automatically reset, preventing damage to the elastic skateboard assembly and the fixed slideway assembly, and reducing the risk of shutdown.

[0017] 2. The distance between the reset mechanism and the head side of the fixed slideway assembly is the same as half of the length dimension of the elastic skateboard assembly, which can enable the reset mechanism to push the middle area at the bottom of the elastic skateboard assembly, ensuring the best effect of the reset force, improving the accuracy and efficiency of the reset, being conducive to the elastic skateboard assembly stably and quickly returning to the normal position, and at the same time ensuring uniform stress on both ends of the elastic skateboard assembly, avoiding uneven stress on one end of the elastic skateboard assembly close to the fixed slideway assembly, and effectively preventing collision damage between the elastic skateboard assembly and the fixed slideway assembly.

[0018] 3. A cleaning mechanism and a purging mechanism are provided on the head side of the fixed slideway assembly. Both the cleaning mechanism and the purging mechanism are located below the elastic slide plate assembly, which can timely remove dust and other sundries below the elastic slide plate assembly, prevent their accumulation from affecting the normal cooperation between the elastic slide plate assembly and the fixed slideway assembly, extend the service life of the equipment, ensure the smooth operation of the elastic slide plate assembly at the same time, and improve the working efficiency of the sintering machine system.

[0019] 4. A dust-proof cover is fixedly installed on the lower plane of the sintering machine. The dust-proof cover can shield and protect the elastic slide plate assembly, prevent the ash material in the sintering machine system from falling onto the surface of the elastic slide plate assembly and into the assembly gap of the elastic slide plate, improve the cleanliness of the surface of the elastic slide plate assembly, and facilitate the subsequent cleaning operation of the elastic slide plate assembly.

[0022] To make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the specific embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0023] Embodiment 1 In a typical implementation manner of the present invention, asFigures 1 - 14 As shown, a side seal safety protection system for a sintering machine is proposed, including: a trolley 1, an elastic slide plate assembly 2, a fixed slideway assembly 3, a cleaning mechanism 5, a purging mechanism 6, a limit detection unit 7, a reset mechanism 8, a dust cover 12 and a control mechanism 13. The elastic slide plate assembly 2 is fixedly installed on the trolley 1 and moves with the trolley 1 to circulate along an elliptical trajectory; the fixed slideway assembly 3 is fixedly installed on the frame of the sintering machine and is located on the upper plane of the sintering machine for cooperating with the elastic slide plate assembly 2 for sealing. The cleaning mechanism 5 and the purging mechanism 6 are arranged in sequence on the head side of the fixed slideway assembly 3 (that is, the side where the elastic slide plate assembly 2 starts to move above the fixed slideway assembly 3; similarly, the tail side of the fixed slideway assembly 3 is the side where the elastic slide plate assembly 2 completely moves out from above the fixed slideway assembly 3), and the cleaning mechanism 5 and the purging mechanism 6 are located below the elastic slide plate assembly 2 to clean the surface of the elastic slide plate assembly 2, remove impurities such as dust to ensure the sealing between the elastic slide plate assembly 2 and the fixed slideway assembly 3; the limit detection unit 7 and the reset mechanism 8 are arranged in sequence on the head side of the fixed slideway assembly 3, the limit detection unit 7 and the reset mechanism 8 are located below the elastic slide plate assembly 2, and the reset mechanism 8 is close to the head side of the fixed slideway assembly 3. Both the limit detection unit 7 and the reset mechanism 8 are connected to the control mechanism 13. The limit detection unit 7 is used to detect whether the elastic slide plate assembly 2 automatically resets, and the reset mechanism 8 is used to assist the elastic slide plate assembly 2 to reset to avoid collision between the elastic slide plate assembly 2 and the fixed slideway assembly 3 when the elastic slide plate assembly 2 slides onto the fixed slideway assembly 3; a dust cover 12 is fixedly installed at the lower plane of the sintering machine to shield and protect the elastic slide plate assembly 2 to prevent the ash material in the sintering machine system from falling onto the surface of the elastic slide plate assembly 2 and into the elastic slide assembly gap.

[0024] As Figure 2 and Figure 3As shown in the figure, the cleaning mechanism 5 includes a connecting rod 501, a first driving motor 502, a cleaning brush 503, a support rod 504, a first support 505, a second support 506, a bearing 507, a first half shaft 508, a second half shaft 509, a coupling 510, a fixing frame 511 and a second spring 512. Among them, the first support 505 and the second support 506 are both fixedly installed on the sintering machine frame. One end of the connecting rod 501 is hinged to the second support 506, and the other end of the connecting rod 501 is rotatably connected to the cleaning brush 503. One end of the support rod 504 is hinged to the first support 505, and the other end of the support rod 504 is fixedly connected to the connecting rod 501 through the second spring 512. A bearing 507 is fixedly installed on the connecting rod 501, and the cleaning brush 503 is rotatably connected to the connecting rod 501 through the bearing 507. Specifically, there are two connecting rods 501 arranged oppositely, and a bearing 507 is installed on each connecting rod 501. A first half shaft 508 and a second half shaft 509 are respectively fixedly installed in the inner holes of the two bearings 507. Connecting grooves are provided on both sides of the cleaning brush 503 and are connected to the corresponding half shafts through the connecting grooves. The half shafts and the connecting grooves are positioned by pins, which can realize the quick disassembly and replacement of the cleaning brush 503. A fixing frame 511 is fixedly installed on one side of the connecting rod 501. The first driving motor 502 is fixedly installed on the fixing frame 511, and the first driving motor 502 is connected to the adjacent half shaft through the coupling 510, so as to realize the rotation control of the cleaning brush 503. The first driving motor 502 is electrically connected to the control mechanism 13 and is used to drive the rotation direction of the cleaning brush 503 to be opposite to the traveling direction of the elastic slide plate assembly 2, improving the cleaning effect and efficiency. The setting of the second spring 512 can ensure the flexible contact between the cleaning brush 503 and the surface of the elastic slide plate assembly 2, preventing the damage of the elastic slide plate assembly 2 and the cleaning brush 503. The setting of the cleaning mechanism 5 can prevent the sintering machine dust from entering the mating surface of the elastic slide plate assembly 2 and the fixed slideway assembly 3 along with the elastic slide plate oil film, and can significantly improve the service life of the elastic slide plate assembly 2 and the fixed slideway assembly 3 and the sealing performance between the two.

[0025] The purging mechanism 6 is a blowing structure and includes a high-pressure nozzle. The high-pressure nozzle is fixedly installed on the sintering machine frame and is connected to a high-pressure gas source. The surface of the elastic slide plate assembly 2 for mating with the fixed slideway assembly 3 can be purged by high-pressure gas to remove the dust on the surface.

[0026] The limit detection unit 7 is a position sensor. The limit detection unit 7 is connected to the control mechanism 13 to detect the position of the middle plate 201 in the elastic slide plate assembly 2 and transmit the detection signal to the control mechanism 13. The control mechanism 13 judges whether the middle plate 201 automatically resets or whether the reset position is qualified according to the detection signal, and coordinates and controls the action of the reset mechanism 8 according to the detection and judgment results.

[0027] As Figure 4As shown, the reset mechanism 8 includes a bracket 801, a limit switch 802, a slider 803, a guide rail 804, a roller 805, a mounting bracket 806, a rack 807, a gear 808, and a second drive motor 809. Among them, the slider 803, the guide rail 804, the rack 807, the gear 808, and the second drive motor 809 form a linear drive assembly. The bracket 801 is vertically and fixedly installed on the sintering machine frame. The limit switch 802, the slider 803, and the second drive motor 809 are all fixedly installed on the bracket 801. The mounting bracket 806 is slidably arranged on the bracket 801. Specifically, the mounting bracket 806 is provided with a guide rail 804, and the guide rail 804 is slidably connected to the slider 803. A rack 807 is fixedly arranged on one side of the mounting bracket 806. The gear 808 is fixedly arranged at the output end of the second drive motor 809. The output end of the second drive motor 809 is engaged with the rack 807 through the gear 808, so as to drive the mounting bracket 806 to move vertically back and forth. The roller 805 is rotatably arranged on the top of the mounting bracket 806. Both the limit switch 802 and the second drive motor 809 are connected to the control mechanism 13. The limit switch 802 is used to safely limit the movement range of the mounting bracket 806, and the control mechanism 13 is used to control the forward and reverse rotation, start and stop time, and operating speed of the second drive motor 809.

[0028] As Figure 6 shown, when it is detected that the floating plate 201 of the elastic sliding plate assembly 2 is not automatically reset in place, the second drive motor 809 controls the vertical movement of the mounting bracket 806, thereby changing the position of the roller 805, so that the roller 805 contacts the floating plate 201 of the elastic sliding plate assembly 2 and pushes the floating plate 201 to reset. Since the reset mechanism 8 is close to the head side of the fixed slideway assembly 3, it can assist the elastic sliding plate assembly 2 to reset and move onto the fixed slideway assembly 3, avoiding the collision between the elastic sliding plate assembly 2 and the head side of the fixed slideway assembly 3.

[0029] To improve the auxiliary effect, the distance between the reset mechanism 8 and the head side of the fixed slideway assembly 3 is the same as half of the length dimension of the elastic sliding plate assembly 2, so that the reset mechanism 8 pushes the middle area at the bottom of the elastic sliding plate assembly 2, improving the reset efficiency and effect of the floating plate 201. Cooperating with the fixed slideway assembly 3, it realizes a smooth and stable transition between the elastic sliding plate assembly 2 and the fixed slideway assembly 3, effectively avoiding the tilting failure of the elastic sliding plate floating plate, and prolonging the service life of the elastic sliding plate assembly 2.

[0030] As Figure 5As shown in the figure, the elastic skateboard assembly includes a floating plate 201, a housing 202, guide posts 203, double nuts 204, connecting screws 205 and a first spring 206. The housing 202 has an open bottom structure. There are several connecting screws 205, which are fixedly arranged at the top of the housing 202 by welding. A double nut 204 is threadedly connected to the connecting screw 205. The housing 202 is fixedly connected to the trolley 1 through the cooperation of the connecting screw 205 and the double nut 204. The bottom of the connecting screw 205 extends into the housing 202 and is connected to the first spring 206. The bottom of the connecting screw 205 is a stepped structure for clamping the first spring 206. A number of guide posts 203 are arranged at intervals along the length direction inside the housing 202. The top of the guide post 203 penetrates the housing 202, and the guide post 203 is slidably connected to the housing 202. The bottom end of the guide post 203 has an external thread, and the guide post 203 is detachably connected to the floating plate 201 by threaded connection. The floating plate 201 is slidably arranged inside the housing 202. A stepped protrusion is welded and fixed on the upper surface of the floating plate 201 for clamping and limiting the first spring 206. Flanges are fixedly arranged at both ends of the floating plate 201 and the top ends of the guide posts 203 to play a role in limiting the floating plate 201. As Figure 7 and Figure 8 As shown in the figure, the fixed slideway assembly 3 includes a first fixed slideway 31, a second fixed slideway 32, a third fixed slideway 33 and a fourth fixed slideway 34 connected in sequence. The first fixed slideway 31 is located on the head side, and the fourth fixed slideway 34 is located on the tail side. An anti-upheaval structure 3101 is fixedly arranged at one end of the first fixed slideway 31 close to the reset mechanism 8. The bottom of the anti-upheaval structure 3101 is fixedly connected to the sintering machine frame through an obliquely arranged reinforcing rod to improve the overall strength of the anti-upheaval structure 3101. The first fixed slideway 31, the second fixed slideway 32, the third fixed slideway 33 and the fourth fixed slideway 34 are all bimetal inlaid composite structures, with high hardness and good wear resistance on the mating surface, and can prevent the impact of the elastic skateboard. Adjacent fixed slideways are butted through connecting protrusions and connecting grooves to improve the connection firmness and tightness.

[0031] The preparation process of the fixed slideway is as follows: Prepare the wear-resistant plate and steel plate according to the process requirements, and perform rough machining according to the drawing dimensions; mill the upper and lower mating surfaces to be compounded on the gantry milling machine into male and female dovetail rabbets for the rough-machined wear-resistant plate and steel plate. At the same time, drill and tap the steel plate; the wear-resistant plate and the steel plate are combined by heating, and the principle of thermal expansion and contraction is used to compound the two steel plates. After compounding, positioning and fastening bolts are added, and the bottom of the fastening bolts is connected to the steel plate to prevent loosening; sufficient machining allowance is left for the fixed slideway during blanking. Chamfers are made around the wear-resistant plate and the steel plate, and the chamfers are welded using carbon dioxide shielded welding. During the welding process, the welded part is struck with a small hammer to eliminate the welding stress; the upper, lower working surfaces and the back of the compounded fixed slideway are machined by a CNC machining center to meet the dimensional requirements. At the same time, chamfers are made for the stress-bearing surface of the fixed slideway; put it into a high-frequency quenching furnace, and use high-frequency quenching to perform surface quenching heat treatment on the upper surface to make the surface hardness of the wear-resistant plate reach 62±2HRC; inspect the dimensions and surface finish, and apply oil for use after passing the inspection.

[0032] As Figure 9 , Figure 10 and Figure 11 shown, the first fixed slideway 31 includes a wear-resistant plate 3102 and a steel plate 3103. The wear-resistant plate 3102 is arranged above the steel plate 3103. The wear-resistant plate 3102 is fixedly connected to the steel plate 3103 through a fastening bolt 3104. Oil holes 3105 are provided on the wear-resistant plate 3102 and the steel plate 3103 for filling lubricating oil. Countersunk holes 3106 are provided on the wear-resistant plate 3102 and the steel plate 3103 for installing the fastening bolt 3104. A chamfer 3107 is provided at the end of the wear-resistant plate 3102 for docking with other fixed slideways to prevent the elastic slide assembly 2 from colliding at the docking of the fixed slideways; an installation groove is provided along the length direction at the bottom of the steel plate 3103, and a packing 3108 (i.e., sealing packing) is provided in the installation groove to improve the sealing performance between the first fixed slideway 31 and the sintering machine.

[0033] The anti-lifting structure 3101 is fixedly installed at the leading end of the first fixed slideway 31 (i.e., the end close to the reset mechanism 8) by means of bolt connection. The anti-lifting structure 3101 includes an arc section, an inclined section and a horizontal section. The arc section is fixedly arranged at one end of the inclined section, and the horizontal section is fixedly arranged at the other end of the inclined section. The arc section is used to contact the elastic slide assembly 2 to play a role of guiding and buffering. The height of the arc section is lower than that of the horizontal section. The horizontal section is fixedly connected to the first fixed slideway 31, and the upper surface height of the horizontal section is the same as the upper surface height of the first fixed slideway 31.

[0034] As Figure 12 shown, the structures of the second fixed slideway 32 and the third fixed slideway 33 are the same as that of the first fixed slideway 31, and they are also double-metal plate inlaid composite structures. Specifically, no more details are described here. As Figure 13and Figure 14 As shown in Figure 14 , the fourth fixed slideway 34 is a bimetal plate inlaid composite structure. One end of the fourth fixed slideway 34 away from the third fixed slideway 33 is detachably connected with a lead-out section, and the lead-out section is a plate-like structure arranged obliquely.

[0035] It further includes a vehicle number photographing unit 4, an alarm unit 9, a display unit 10, and a skateboard photographing unit 11. The vehicle number photographing unit 4, the alarm unit 9, the display unit 10, and the skateboard photographing unit 11 are all connected to the control mechanism 13. The skateboard photographing unit 11 is used to photograph the elastic skateboard assembly 2, and the vehicle number photographing unit 4 is used to photograph the number of the trolley 1. The control mechanism 13 can record and store the trolley number corresponding to the abnormal elastic skateboard, so as to stop the machine at an opportune moment to replace the trolley 1 and the brand-new elastic skateboard assembly 2, avoiding the expansion of the fault. Specifically, the control mechanism 13 can display and compare the image taken by the skateboard photographing unit 11 with the standard skateboard image stored in the control mechanism 13. When there is an abnormal situation (such as wear of the skateboard of the elastic skateboard, drooping or breaking of the end), it alarms through the alarm unit 9 and uses the display unit 10 to display the real-time tracking screen.

[0036] Embodiment 2 In another typical implementation manner of the present invention, a protection method is proposed as follows: The elastic skateboard assembly 2 follows the trolley 1 to move forward and runs in a cyclic reciprocating manner along an elliptical track. First, the elastic skateboard assembly 2 follows the trolley 1 through the lower plane of the sintering machine, and the dust cover 12 conducts the first protection on the skate 201 of the elastic skateboard assembly 2 to prevent the ash material in the sintering machine system from falling onto the surface of the skate 201 and into the assembly gap of the elastic skateboard assembly 2. Then the elastic skateboard assembly 2 follows the trolley 1 to rotate from bottom to top along the left half-elliptical track to the upper plane of the sintering machine. Inevitably, dust will fall into and adhere to the oil film of the skate 201 during the flipping process. Continuing to move forward to the right, the cleaning mechanism 5 and the purging mechanism 6 will clean and blow the dust on the skate 201. Subsequently, the cleaned elastic skateboard assembly 2 passes through the skateboard photographing unit 11. The skateboard photographing unit 11 transmits the real-time image of the skateboard surface into the control mechanism 13 and compares it with the standard image stored in the control mechanism 13. When there is an abnormal situation (such as wear of the skateboard of the elastic skateboard, drooping or breaking of the end), it alarms through the alarm unit 9 and uses the display unit 10 to display the real-time tracking screen. At the same time, the control mechanism 13 controls the vehicle number photographing unit 4 to photograph and record the trolley number corresponding to the abnormal elastic skateboard assembly 2, and stops the machine at an opportune moment to replace the trolley 1 and the brand-new elastic skateboard assembly 2 (specifically, the skate 201), avoiding the expansion of the fault. When only the situation that the movable plate 201 fails to self-reset occurs, the elastic slide plate assembly 2 continues to move rightward along the upper plane following the trolley 1. The position of the movable plate 201 is detected in real time by the limit detection unit 7. When it is detected that the position of the movable plate 201 has not been self-reset in place, the limit detection unit 7 transmits a signal to the control mechanism 13, and the control mechanism 13 controls the car number photographing unit 4 to photograph and record and store the trolley number; at the same time, the control mechanism 13 controls the reset mechanism 8 to perform a contact reset on the movable plate 201. Specifically, the second drive motor 809 controls the mounting frame 806 to move upward, contacts the movable plate 201 through the roller 805 and pushes the movable plate 201 to reset, so that the height of the lower surface of the movable plate 201 is not lower than the arc height of the anti-tipping structure 3101. The elastic slide plate assembly 2 stably passes over the rear fixed slide way assembly 3 in sequence. With the stable cooperation effect of the fixed slide way and the elastic slide plate and the resistance reduction and sealing effects of the lubricating oil on the slide way mating surface, stable sliding operation between the elastic slide plate and the fixed slide way of the sintering machine is realized. After the elastic slide plate assembly 2 is moved out from the tail side of the fixed slide way assembly 3, the elastic slide plate assembly 2 is replaced opportunely.
