Description

Technical Field

[0001] This invention relates to the field of sintering technology, and in particular to an online sintering machine trolley replacement device and a sintering machine system. Background Technology

[0002] The sintering machine trolley is one of the important components of the sintering machine. There are many of them, and they work in a harsh environment. Due to the harsh working environment, the grate bars, side plates, and wheel bearings of the sintering machine trolley are all wear parts. When the wear parts of the trolley reach the end of their service life, the entire trolley must be lifted out for replacement and maintenance of the wear parts. At the same time, a new trolley must be lifted in to ensure the normal operation of the sintering machine.

[0003] Currently, the replacement process for sintering machine trolleys is complex. The traditional method for replacing sintering machine trolleys is to stop the feeding device, allow the faulty trolley to run empty to a suitable position at the tail of the machine, stop the sintering machine, start the tail hydraulic device to move the tail moving frame backward so that the faulty trolley has no thrust in front and behind, and then lift the faulty trolley out of the sintering machine for replacement.

[0004] This replacement method is convenient for sintering machines that are not yet in production or under construction, as there is no material on the trolley to be cleaned. However, it has the following disadvantages for replacing trolleys on sintering machines in production: 1. Long downtime, usually more than one hour. After feeding stops at the faulty trolley, the igniter needs to be reduced to prevent damage to the trolley before it is moved to a suitable lifting position and stopped for lifting. 2. Impact on sinter quality. Downtime will cause fluctuations in the sintering production process, reducing the quality of the sinter. 3. Material cleaning and machine shutdown are required when the lifting equipment is in operation, and the installation of the lifting equipment requires a large space. Manual assistance is needed on-site during the lifting process of the trolley, posing certain safety risks.

[0005] In view of this, it is necessary to propose an online sintering machine trolley replacement device and a sintering machine system to solve or at least alleviate the above-mentioned defects. Summary of the Invention

[0065] Please see the appendix Figures 1 to 24 An online replacement device for a sintering machine trolley in one embodiment of the present invention includes a trolley actuation mechanism 10, a trolley lifting-out assembly 20 and a trolley lifting-in assembly 30 arranged at intervals along the return direction of the sintering machine trolley 60, wherein the trolley lifting-in assembly 30 is located in front of the trolley lifting-out assembly 20 in the return direction; wherein, the present application achieves the lifting out of the trolley 610 to be replaced and the lifting in of the new trolley 620 by setting two sets of lifting tools, namely the trolley lifting-out assembly 20 and the trolley lifting-in assembly 30.

[0066] The trolley actuation mechanism 10 includes a worktable 110 and a third track 120 located below the worktable 110. The third track 120 is located below the return trolley and extends along the return direction of the sintering machine trolley 60. The worktable 110 is movably mounted on the third track 120. The worktable 110 is used to move the sintering machine trolleys 60 located on both sides before and after the trolley 610 to be replaced, so that the trolley 610 to be replaced is in an isolated state (i.e., a free state). Those skilled in the art should know that the sintering machine trolleys 60 in the return state run on the return track of the sintering machine (not shown in the figure), and there is a significant interaction force between the sintering machine trolleys 60. The worktable 110 runs on the third track 120 below the sintering machine trolleys 60. When a sintering machine trolley 60 is damaged and needs to be replaced or repaired, the worktable 110 can be controlled to move to the corresponding position to begin the replacement operation. In a preferred embodiment, the third track 120 can be fixed on the sintering machine frame 70.

[0067] The trolley lifting assembly 20 includes a first lifting assembly 210 and a first track 220 located between the return trolley and the sintering machine frame 70. The first track 220 extends laterally along the sintering machine and extends from inside the sintering machine to outside the sintering machine. The first lifting assembly 210 is used to lift the trolley 610 to be replaced upward and transport it outward along the first track 220 to outside the sintering machine.

[0068] The trolley hoisting assembly 30 includes a second lifting assembly 310 and a second track 320 located between the return trolley and the sintering machine frame 70. The second track 320 extends laterally along the sintering machine and from the inside of the sintering machine to the outside of the sintering machine. The second lifting assembly 310 is used to lift the new trolley 620 and transport it inward along the second track 320 into the sintering machine so as to load the new trolley 620 into the installation space 130 vacated by the trolley 610 to be replaced.

[0069] Preferably, the first track 220 and the second track 320 are positioned close to the return position of the sintering machine head. The ambient temperature is lower in this position, and the thrust between the trolleys is smaller, which makes it easier to change the sintering machine trolley 60 online.

[0070] In a preferred embodiment, the first lifting assembly 210 includes a first moving trolley 211 and a first electromagnet chuck 212. The first moving trolley 211 is movably disposed along the extension direction of the first track 220, and the first electromagnet chuck 212 is connected below the first moving trolley 211 and moves synchronously with the first moving trolley 211. The first moving trolley 211 and the second moving trolley 311 (hereinafter referred to as the second moving trolley) can be either the currently mature moving trolleys of gantry cranes or electric hoists.

[0071] In a preferred embodiment, the second lifting assembly 310 includes a second moving trolley 311 and a second electromagnet chuck 312. The second moving trolley 311 is movably disposed along the extension direction of the second track 320, and the second electromagnet chuck 312 is connected to the lower part of the second moving trolley 311 and moves synchronously with the second moving trolley 311.

[0072] Specifically, this application uses two sets of lifting devices (trolley lifting-out component 20 and trolley lifting-in component 30), such as... Figure 1 As shown, when the sintering machine trolley 60 needs to be replaced or repaired, the trolley 610 to be replaced can be lifted under the trolley lifting assembly 20 via the workbench 110, or the suspension end of the first moving trolley 211 can be lowered to above the trolley 610 to be replaced. After the first electromagnet chuck 212 is energized, it generates an adsorption force to hold the sintering machine trolley 60. The first moving trolley 211 is then started and transported along the extension direction of the first track 220 to the external equipment space of the sintering machine. The new trolley 620 is transported to the return running track of the sintering machine trolley 60 via the trolley lifting assembly 30. When the empty space after the old trolley is transported is close to the bottom of the trolley lifting assembly 30, the trolley lifting assembly 30 places the new trolley 620 on the workbench body 112 and places it in the original position of the old trolley via the workbench body 112. This allows for unmanned online replacement of the sintering machine trolley 60.

[0073] In a preferred embodiment, the workbench 110 includes a trolley actuation assembly 111, a workbench body 112 corresponding to the sintering machine trolley 60, and a lifting device 113 located on top of the workbench body 112; wherein,

[0074] The workbench body 112 is movably mounted on the third track 120. The workbench body 112 includes a first side 1121 and a second side 1122 that are arranged opposite to each other along the return direction.

[0075] The trolley actuation assembly 111 includes a first drive assembly 1111 disposed on the first side 1121 and a second drive assembly 1112 disposed on the second side 1122. The first drive assembly 1111 is used to drive the sintering machine trolley 60 near the first side 1121 to move in a first direction, and the second drive assembly 1112 is used to drive the sintering machine trolley 60 near the second side 1122 to move in a second direction, so as to move the sintering machine trolley 60 near the first side 1121 and the sintering machine trolley 60 near the second side 1122 in a second direction. The sintering machine trolley 60 of 22 is separated from the trolley to be replaced 610; wherein the first direction and the second direction are opposite; for example, along the return direction, the first side 1121 is in front of the second side 1122, so the sintering machine trolley 60 located in front of the trolley to be replaced 610 can be pushed aside by the first drive assembly 1111 to separate it from the trolley to be replaced 610, and the second drive assembly 1112 can push aside the sintering machine trolley 60 located behind the trolley to be replaced 610 to separate it from the trolley to be replaced 610.

[0076] In a preferred embodiment, both the first drive assembly 1111 and the second drive assembly 1112 include a drive unit 1113, a bracket 1114, and a chuck actuation mechanism (not shown in the figure). The bracket 1114 is connected to the top of the worktable 110, and the chuck actuation mechanism is hinged to the top of the bracket 1114. The rotation path of the chuck actuation mechanism intersects the chuck axis of the corresponding sintering machine trolley 60. The drive unit 1113 drives the chuck actuation mechanism to rotate around the hinge point to the chuck of the corresponding sintering machine trolley 60, thereby pushing the corresponding sintering machine trolley 60 to move along the return track direction and separate it from the trolley 610 to be replaced. The drive unit 1113 can be a hydraulic cylinder.

[0077] As a preferred example, there are two of each of the first drive assembly 1111 and the second drive assembly 1112. The two first drive assemblies 1111 are arranged opposite each other along the length of the worktable body 112, and the two second drive assemblies 1112 are arranged opposite each other along the length of the worktable body 112.

[0078] As a preferred example, the support 1114 includes two support plates (not shown) arranged parallel to each other along the length of the workbench body 112. The support plates are connected to the top of the workbench body 112. Each support plate has a first shaft hole (not shown) through which a first hinge shaft (not shown) passes. The chuck actuation mechanism has a second shaft hole (not shown) corresponding to the first shaft hole. The chuck actuation mechanism is hinged between the two support plates through the first hinge shaft passing through the first shaft hole and the second shaft hole.

[0079] In a preferred embodiment, the chuck actuation mechanism includes a chuck contact block 1115 and a fan-shaped connecting block 1116. The connecting block 1116 has a third shaft hole and a first connecting hole for bolt connection. The chuck contact block 1115 has a second connecting hole corresponding to the first connecting hole. The chuck contact block 1115 is connected to the connecting block 1116 by bolts passing through the first connecting hole and the second connecting hole.

[0080] Furthermore, the chuck contact block 1115 has an arc-shaped groove 1117 that matches the chuck of the sintering machine trolley 60. By setting the arc-shaped groove 1117, when the chuck of the sintering machine trolley 60 is turned, the arc-shaped groove 1117 matches the chuck, and the drive unit 1113 drives the chuck contact block 1115 to contact the chuck, thereby more stably separating adjacent sintering machine trolleys 60.

[0081] Furthermore, the workbench body 112 includes an AGV body 1123 and a horizontal plate 1124 connected to the top of the AGV body 1123. The wheels 630 of the AGV body 1123 are movably mounted on the third track 120, and the trolley actuation mechanism 10 is connected to the top of the horizontal plate 1124. It should be noted that the AGV body 1123 can run along the third track 120 and has the function of automatically resetting to its initial position. This function is a mature existing technology and will not be elaborated upon here. The automatic reset of the workbench body 1122 based on the AGV body 1123 automates the entire trolley replacement process, saving manpower.

[0082] The lifting device 113 is used to lift the trolley 610 to be replaced to below the first lifting assembly 210 for the first lifting assembly 210 to lift it, and to lower the new trolley 620 lifted from the second lifting assembly 310 into the installation space 130 vacated by the trolley 610 to be replaced.

[0083] In a preferred embodiment, the lifting device 113 includes a first drive mechanism (not shown), a base plate 1131, a folding frame 1132, and a top plate 1133. The base plate 1131 is fixedly mounted on the top surface of the workbench body 112, and the top plate 1133 is located directly above the base plate 1131. The folding frame 1132 connects the top plate 1133 and the base plate 1131. When the first drive mechanism drives the folding frame 1132 to rise vertically, it also drives the top plate 1133 to rise, thereby lifting the trolley 610 to be replaced below the first lifting assembly 210 for lifting. When the first drive mechanism drives the folding frame 1132 to descend, it also drives the top plate 1133 to descend, thereby lowering the new trolley 620 into the installation space 130 vacated by the trolley 610 to be replaced.

[0084] In another embodiment, the lifting device 113 is a scissor lift platform, the top of which corresponds to the grate surface of the sintering machine trolley 60, and the bottom of which is installed on the top of the worktable body 112. The scissor lift platform is a mature existing technology and will not be described in detail here.

[0085] Workflow: When a damaged trolley (i.e., trolley 610 to be replaced) is discovered, the movable workbench body 112 is positioned in its initial position. The damaged trolley moves to the initial position of the workbench body 112 under the action of the trolley group. At this time, the fan-shaped chuck contact blocks 1115, driven by the hydraulic rod of the drive unit 1113 (such as a hydraulic actuator), begin to move the chucks of the two sintering machine trolleys 60 in front of and behind the damaged trolley to both sides, thus providing sufficient space for the smooth lifting out of the damaged trolley and the hoisting of the new trolley 620. Figure 11As shown. The drive unit 1113 pulls the front and rear carriages apart by a certain distance and holds them stationary, typically 50-100mm. Then, with the roller contact block 1115 pushing aside the sintering machine carriages 60 on both sides, the worktable 110 continues to move forward synchronously with the sintering machine carriages 60 due to the thrust of the carriages 60. At this time, the worktable body 112 remains relatively stationary with the damaged carriage. This allows the worktable body 112 to replace the damaged carriage even without stopping the sintering machine, in conjunction with the lifting device 113 and the corresponding crane device. During the synchronous movement, the AGV body 1123 does not provide power. After the roller contact block 1115 pushes aside the sintering machine carriages 60 on both sides of the damaged carriage, leaving a certain gap, the lifting device 113 can lift the damaged carriage, creating working conditions for the crane to lift it. After the crane removes the damaged trolley, the new trolley 620 can be hoisted onto the lifting device 113. The lifting device 113 then lowers to reinstall the new trolley 620 into the sintering machine. Finally, the drive unit 1113 gradually retracts, and the chuck contact block 1115 retracts under the drive of the drive unit 1113 and is reset by the AGV body 1123, completing one replacement operation for the damaged trolley.

[0086] As a preferred embodiment, it also includes a first trolley tilting mechanism 40 located outside the sintering machine. The first track 220 includes a first connecting end 221 and a first cantilever end 222 arranged opposite to each other along its own extension direction. The first connecting end 221 is fixedly connected to the sintering machine frame 70, and the first cantilever end 222 is located outside the sintering machine. The first trolley tilting mechanism 40 is used to tilt the trolley 610 to be replaced from the tilted state with the wheels 630 facing upwards to the normal state with the wheels 630 facing downwards.

[0087] And / or may also include a second trolley tilting mechanism 50 located outside the sintering machine. The second track 320 includes a second connecting end 321 and a second cantilever end 322 arranged opposite to each other along its own extension direction. The second connecting end 321 is fixedly connected to the sintering machine frame 70. The second cantilever end 322 is located outside the sintering machine. The second trolley tilting mechanism 50 is used to tilt the trolley 610 to be replaced from the normal state with the wheels 630 facing down to the tilted state with the wheels 630 facing up.

[0088] In another preferred embodiment, the first trolley tilting mechanism 40 includes a second drive mechanism (not shown in the figure), two rotating mechanisms 420 oppositely arranged on both sides of the trolley to be tilted, and two wheel limiting rails 430 oppositely arranged on both sides of the trolley to be tilted. The rotating mechanisms 420 and the wheel limiting rails 430 are arranged in a one-to-one correspondence.

[0089] The rotating mechanism 420 has a wheel slot 423 that matches the wheel 630 of the trolley to be tilted.

[0090] The wheel limiting track 430 is laid on the outside of the rotating mechanism 420, and a radial limiting space 424 matching the wheel 630 of the trolley to be overturned is formed between the wheel limiting track 430 and the wheel slot 423.

[0091] The second driving mechanism is used to drive the rotating mechanism 420 to rotate, thereby causing the wheels 630 of the trolley to be overturned located in the radial limiting space 424 to move along the extension direction of the wheel limiting track 430, so as to realize the overturning of the trolley.

[0092] The first trolley tilting mechanism 40 provided in this embodiment can realize the continuous tilting of multiple sintering machine trolleys 60. The operator only needs to hoist the trolley to be tilted onto the rotating mechanism 420, which greatly reduces the risk of accidents on site. In this application, the drive mechanism can be used only on both sides or one side, ensuring that the site space is not occupied when the trolley is not tilted, which facilitates the maintenance of other projects. With the wheel limit rail 430, the drive mechanism can achieve trolley tilting with a small torque. The structure is simple and occupies a small area. At the same time, the design of the rail in this application ensures that the trolley tilts safely and stably, without the risk of tipping over or falling.

[0093] Furthermore, each of the wheel limiting tracks 430 includes an arc-shaped segment 431 and a horizontal segment 432 that are connected to each other along its own extension direction. The horizontal segment 432 and the arc-shaped segment 431 are tangent to each other. The horizontal segment 432 is located below the rotating mechanism 420. The arc-shaped segment 431 extends upward from the horizontal segment 432 around the rotating mechanism 420 to the top of the rotating mechanism 420.

[0094] like Figure 22 As shown, since the arc segment 431 can limit the radial movement of the wheel 630, in order to ensure that the arc segment 431 does not affect the contact between the newly hoisted trolley to be tilted and the wheel slot 423, and to prevent the wheel 630 of the trolley to be tilted from coming out of the wheel slot 423 due to its own weight, the central angle of the arc segment 431 in this embodiment is set between 120° and 150°. That is, the trolley to be tilted is located above the rotating mechanism 420 and the wheel 630 of the trolley to be tilted is engaged in the wheel slot 423. At this time, the trolley to be tilted is basically in a vertical state. After the rotating mechanism 420 rotates, the wheel 630 of the trolley to be tilted enters the coverage area of ​​the arc segment 431, thereby realizing the radial limitation of the wheel 630 by the arc segment 431.

[0095] Furthermore, the rotating mechanism 420 is a spoke 421, and the spoke 421 has a plurality of wheel slots 423, which are evenly spaced along the circumference of the spoke 421. As a preferred example, the number of wheel slots 423 is set to 6. In other embodiments, the number of wheel slots 423 can be set to other numbers, as long as the outer diameter of the wheel slots 423 matches the outer diameter of the wheel 630, and the distance between two adjacent wheel slots 423 matches the distance between two wheels 630 on one side of the sintering machine trolley 60, so that the wheels 630 can be engaged.

[0096] As a preferred implementation, such as Figure 21 As shown, the second drive mechanism includes a drive motor 411, a reduction mechanism 412 (e.g., a gear reduction mechanism 412), a frame 413, and a rotating shaft 414; wherein, the output end of the drive motor 411 is connected to the input end of the reduction mechanism 412, the output end of the reduction mechanism 412 is connected to the rotating shaft 414 via a coupling 415, a bearing seat 416 for mounting the rotating shaft 414 is mounted on the top of the frame 413, and the rotating mechanism 420 is connected to the rotating shaft 414 and rotates synchronously with the rotating shaft 414.

[0097] Specifically, the drive motor 411 preferably adopts a built-in brake motor, which can brake in time as needed to reduce the risk of accidents. When the drive motor 411 runs, it drives the reduction mechanism 412 to run. The reduction mechanism 412 reduces the speed of the drive motor 411, and then drives the rotating shaft 414 to run, thereby driving the rotating mechanism 420 connected to the rotating shaft 414 to run, and then driving the trolley to be turned to rotate synchronously, thereby completing the turning of the trolley to be turned.

[0098] Furthermore, the spoke 421 has a through hole 422 for the rotating shaft 414 to pass through. The rotating shaft 414 is mounted on the bearing seat 416 and extends out of the bearing seat 416 for a period of time before passing through the through hole 422 and connecting to the spoke 421.

[0099] It is also worth noting that the number of drive mechanisms in this application can be set to one or two, for example... Figure 21 It can be a single-drive type, with the drive mechanism set only on one side, or the drive mechanism can be set on both sides of the sintering machine trolley 60, i.e., a dual-drive type is also possible.

[0100] In a preferred embodiment, a stop mechanism 440 is provided at the end of the horizontal segment 432 away from the arc-shaped segment 431. The stop mechanism 440 can be a stop iron or other type of stop that can stop the sintering machine trolley 60. Further, the stop mechanism 440 is a stop iron. Since the stop iron is relatively heavy, it can be placed directly on the horizontal segment 432, connected to the horizontal segment 432, or integrally formed with the horizontal segment 432. By providing the stop iron, after the sintering machine trolley 60, which is in a flipped state (wheels 630 facing upwards), flips back to its normal state, the sintering machine trolley 60 will continue to move along the horizontal segment 432 due to its own potential energy. The stop iron's stopping action promptly stops the sintering machine trolley 60.

[0101] In another embodiment, an anti-tipping detection device (not shown in the figure) can also be provided, such as an angle sensor. This sensor detects outward tilting of the sintering machine trolley when it becomes misaligned behind the wheel slot 423. Once the angle sensor detects the outward displacement of the trolley (e.g., a 10-degree rightward deflection), the machine stops immediately, and the built-in brake device of the drive motor 411 engages, locking the drive mechanism to prevent accidents. The position of the anti-tipping detection device can be set according to actual needs, as long as it can detect a certain deflection angle of the sintering machine trolley 60.

[0102] Workflow: In the initial state, the drive motor 411 is braked and locked. The trolley to be tilted, taken from the sintering machine, is hoisted into the tilting device of this application. Once the trolley is securely placed on the toothed plate, the lifting device is removed, and preparation for tilting begins. The drive motor 411 rotates, causing the rotating shaft 414 to rotate, which in turn causes the spokes 421 connected to the rotating shaft 414 to rotate 180°. The trolley to be tilted then... Figure 22 Change to Figure 24 The sintering machine trolley 60 rotates smoothly and naturally under the drive. After the rotation is complete, the trolley naturally leaves the arc section 431 and can then be manually lifted away. Similarly, a new trolley 620 to be sent into the sintering machine is lifted into the horizontal section 432 and placed smoothly. After the wheels 630 enter the radial limiting space 424, it rotates 180° in the opposite direction to the flipped state and is then sent into the sintering machine by a lifting device.

[0103] In a preferred embodiment, the second trolley tilting mechanism 50 includes a third drive mechanism 510, a rotating trolley body 520, and two trolley fastening mechanisms 540 arranged opposite each other along the length of the rotating trolley body 520; wherein...

[0104] The rotating car body 520 has a side panel 640 insertion hole 530 for the side panel 640 of the sintering machine trolley 60 to be partially inserted.

[0105] Each of the trolley fastening mechanisms 540 includes a locking rope 541 and a connecting mechanism 542 for winding the locking rope 541. The connecting mechanism 542 is connected to the rotating car body 520 and corresponds in position to the wheel 630 of the sintering machine trolley 60. The locking rope 541 passes through the connecting mechanism 542 and is wound around the outer periphery of the wheel 630 of the sintering machine trolley 60. The side panel 640 of the sintering machine trolley 60 partially passes through the side panel 640 insertion hole 530 to fasten the sintering machine trolley 60 to the rotating car body 520. The third drive mechanism 510 is used to drive the rotating car body 520 to rotate so as to realize the sintering machine trolley 60 flipping. As a preferred example, the locking rope 541 is a steel wire rope, the connecting mechanism 542 is a hook, and the third drive mechanism 510 can adopt a structure similar to the second drive mechanism, that is, the drive unit 1113 includes a drive motor 411, a reduction mechanism 412 (e.g., a gear reduction mechanism 412), a frame 413, and a rotating shaft 414; wherein, the output end of the drive motor 411 is connected to the input end of the reduction mechanism 412, and the output end of the reduction mechanism 412 is connected to the rotating shaft 414 through a coupling 415;

[0106] The rotating shaft 414 includes an intermediate section (not shown in the figure) and two trunnion sections (not shown in the figure) connecting the two ends of the intermediate section;

[0107] Each of the side mounting plates has a through hole 422 for the trunnion segment to pass through, and the trunnion segment is rotatably mounted on the frame 413 through the through hole 422.

[0108] Furthermore, the frame 413 includes a bracket 1114 and two bearing seats 416 disposed opposite to each other at both ends of the rotating shaft 414. The bearing seats 416 are mounted on the bracket 1114, and the two trunnion sections of the rotating shaft 414 are respectively connected to the corresponding bearing seats 416.

[0109] Workflow: The sintering machine trolley 60, which needs to be flipped, rests on the rotating body 520. The side panels 640 of the sintering machine trolley 60 are inserted into the side panel 640 insertion holes 530 of the rotating body 520. The sintering machine trolley 60 and the rotating body 520 are fixed together by steel wire ropes and hooks. The third drive mechanism operates, driving the rotating shaft 414 to rotate. The rotating shaft 414 drives the rotating body 520 connected to it to rotate, so that the sintering machine trolley 60 rotates synchronously. After the sintering machine trolley 60 rotates 180°, the third drive mechanism brakes and locks, releasing the steel wire ropes so that the sintering machine trolley 60 falls onto the lifting trolley (not shown in the figure) by its own weight, realizing the flipping of the sintering machine trolley 60 from the "flipped state" to the "normal state". Similarly, the new trolley 620 to be sent into the sintering machine can be fixed on the rotating car body 520 by winding the hook above with a steel wire rope, controlling the third drive mechanism to rotate 180° from the "normal state" to the "tilting state", and then sent into the sintering machine by a lifting device.

[0110] It should be noted that after moving to the outside of the sintering machine, the trolley can be transferred to the first trolley tilting mechanism 40 or the second trolley tilting mechanism 50 using a mobile trolley lift or forklift to tilt the trolley for easy maintenance or hoisting. Afterwards, the old trolley can be hoisted to the main plant for further processing using an overhead crane. The loading process for the new trolley 620 is the reverse.

[0111] It is worth noting that in other embodiments, the first trolley tilting mechanism 40 and the second trolley tilting mechanism 50 can also be configured in the same form, for example, both being the structure of the first trolley tilting mechanism 40 described above. In another embodiment, the first trolley tilting mechanism 40 and the second trolley tilting mechanism 50 can also be configured as one, that is, when it is necessary to tilt the trolley 610 to be replaced to the normal state, the trolley 610 to be replaced can be transferred to the trolley tilting device for tilting by a mobile trolley lift or forklift, or the new trolley 620 can be transferred to the trolley tilting device for tilting. Those skilled in the art can configure it as needed.

[0112] Furthermore, the first track 220 and the second track 320 are on the same horizontal plane, and are arranged in parallel with each other. In other embodiments, the first track 220 and the second track 320 may not be parallel or on the same horizontal plane, as long as the first track can lift the trolley 610 to be replaced out of the sintering machine, and the second track 320 can lift the new trolley 620 from outside the sintering machine into the sintering machine.

[0113] The present invention also provides a sintering machine system, including a sintering machine body and a plurality of sintering machine trolleys 60 running on the sintering machine body, and further including an online replacement device for the sintering machine trolleys 60 as described above.

[0114] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
