Description

Technical Field

[0001] The present invention relates to the technical field of sintering machines, and more particularly to a device for eliminating arching and deviation of a sintering machine trolley. Background Art

[0002] The sintering machine trolley is the core component of the sintering machine, and its stable operation is crucial to the entire system. However, in actual production, this trolley suffers from problems such as arching and deviation. Currently, major sintering plants use intelligent sintering machine trolley management systems, which generally provide functions such as detection, identification, and early warning, but lack problem-solving capabilities.

[0003] Arching: During the operation of the belt sintering machine, when the trolley passes the tail star wheel and the tail curve into the lower horizontal track (return track), during the driving process, the tail star wheel gear plate pushes the trolley forward. The front working surface of the gear plate contacts the trolley rear wheel sleeve and generates a thrust Fz that causes the trolley to move toward the tangent plane. This force has a horizontal force Fd and an upward friction component Ff. The greater the thrust, the greater the friction component. When the torque generated by the friction component is greater than the torque of the trolley's own weight, the trolley rear wheel will be lifted upward, and the star wheel continues to rotate. At the moment the trolley's sleeve leaves the gear plate, the front end of the trolley behind it contacts it and squeezes it tightly, preventing it from falling onto the track. In this cycle, each trolley will go through this force process, causing the trolley on the return track to have a shoulder arching phenomenon. Two methods are usually used to solve the trolley arching problem in the existing technology. First, the use of dedicated boss rails locally alters the trajectory, reducing the torque generated by the friction component and thus reducing the arching of the sintering machine trolley. Existing dedicated rails are worn, difficult to replace, and difficult to repair, posing construction risks. Replacement is time-consuming and costly. Second, the use of fixed pressure rails solves the problem by forcing the trolley without eliminating friction. This method increases wear on the trolley end, forming triangular grooves that lead to air leakage and reduced production. Furthermore, incomplete corrections can still cause varying degrees of arching in the trolley, increasing the load on the motor and damaging the motor, the sintering machine frame, and the trolley rails, leading to accidents such as trolley derailment.

[0004] Deviation: The main reason for the deviation of the trolley is that during the production process, the frame, bellows, and the driving wheels at the head and tail of the track are affected by the long-term heat load, which causes the metal material to deform. In addition, the uneven settlement of the factory foundation and other factors have destroyed the original installation accuracy, resulting in the deviation of the trolley during operation. The deviation of the trolley will have many adverse effects on the equipment itself and production, such as: reducing the life of the trolley wheels and their inner cavity parts, wear and displacement of the trolley track, abnormal operation of the head and tail of the machine, etc. The abnormal operation of the head and tail of the machine will cause deformation of the relevant components of the curve. At the same time, this deformation will aggravate the deviation of the trolley. This vicious cycle will continue until the trolley is off the track. After the trolley is off the track, it will take a lot of time to repair and restore the equipment, which will seriously affect the production rhythm.

[0005] The intelligent management system of the sintering machine trolley generally provides operation status management of the sintering machine trolley through video recognition, laser ranging, track weighing, etc., but it is limited to early warning functions. When the system determines that the sintering machine trolley has arching or deviation, manual adjustment and intervention are required, and it cannot automatically eliminate the arching and deviation phenomena.

[0006] In order to solve the above problems, it is urgently necessary to provide a device for eliminating the arching and deviation of a sintering machine trolley. Summary of the Invention

[0007] In view of the above problems, the purpose of the present invention is to provide a device for eliminating arching and deviation of a sintering machine trolley, so as to solve the problems of arching and deviation of the existing sintering machine trolley in actual production.

[0008] The device for eliminating arching and deviation of a sintering machine trolley provided by the present invention is arranged at positions corresponding to the two trolley running tracks of the sintering machine trolley, and includes two sets of lifting track assemblies respectively connected to the two trolley running tracks, and a power system providing power to the two sets of lifting track assemblies, wherein:

[0009] The power system includes two power devices corresponding to the two sets of lifting track assemblies respectively, and each power device corresponds to a set of lifting track assemblies;

[0010] Each lifting track assembly includes a first track located in the middle, and second tracks respectively provided at both ends of the first track, and the first track and the second tracks respectively provided at both ends are connected to each other, and each power device is connected to the first track of each lifting track assembly;

[0011] The first track of each track assembly drives the second tracks at both ends of the first track to rise and fall under the action of the corresponding power device, thereby eliminating the arching or deviation of the sintering machine trolley.

[0012] In addition, the preferred solution is that when two power devices act on the corresponding lifting track components at the same time,

[0013] The two sets of lifting rail assemblies are lifted simultaneously to form an arched rail, so as to eliminate the arching of the sintering machine trolley.

[0014] In addition, a preferred solution is that when one of the two power devices acts on the corresponding lifting track assembly,

[0015] The lifting track assembly corresponding to a power device is lifted to tilt the sintering machine trolley in the horizontal direction. The driving force of the sintering machine trolley in the tilted state and the combined force of gravity can eliminate the deviation of the sintering machine trolley.

[0016] In addition, a preferred solution is that the power device is a hydraulic cylinder or a pneumatic cylinder.

[0017] In addition, a preferred solution is that the two sets of lifting track assemblies are respectively connected to the corresponding trolley running tracks by means of hinges.

[0018] In addition, a preferred solution is that the first rails in each set of lifting rail assemblies are respectively connected to the second rails in a hinged manner.

[0019] In addition, a preferred solution is that the first track includes a first track bracket and a first track body, wherein:

[0020] The first track bracket is formed by welding I-beams, and the first track body is formed by welding 50Mn square steel and Q235 steel plate.

[0021] In addition, a preferred solution is that the power device is installed below the first track bracket.

[0022] In addition, a preferred solution is that the second track includes a second track bracket and a second track body, wherein:

[0023] The second track bracket is welded by two vertical plates, and the second track body is welded by 50Mn square steel and Q235 steel plate;

[0024] The second track is connected to the trolley running track through the double vertical plates.

[0025] In addition, a preferred solution is to further include a management system, wherein:

[0026] The management system is used to control the power system to lift and lower the two sets of lifting track components.

[0027] It can be seen from the above technical solutions that the device for eliminating arching and deviation of a sintering machine trolley provided by the present invention can eliminate the arching of the sintering machine trolley by simultaneously pushing two sets of lifting rail assemblies up and down through a power system; a set of lifting rail assemblies is pushed up and down by one of the power devices, so that the sintering machine trolley is tilted in the horizontal direction, and the deviation of the sintering machine trolley is eliminated by relying on the combined force formed by the driving force of the sintering machine and gravity; the present invention can solve the problem of arching or deviation of the sintering machine trolley at the same time through the interaction between the power system and the two sets of lifting rail assemblies.

[0045] In response to the aforementioned problems of arching and deviation of the existing sintering machine trolley in actual production, the present invention provides a device for eliminating arching and deviation of the sintering machine trolley.

[0046] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0047] In order to illustrate the structure of the device for eliminating the arching and deviation of the sintering machine trolley provided by the present invention, Figures 1-11 The camber and deviation elimination device of the sintering machine trolley is illustrated from different angles. Specifically, Figure 1 It shows the normal operating state of the sintering car and the recovery state of the power system according to an embodiment of the present invention; Figure 2 Shown Figure 1 The left-view structure; Figure 3 It shows the sintering car trolley arching state according to an embodiment of the present invention, and the device is not started; Figure 4 shows two sets of lifting track assemblies simultaneously lifting a structure according to an embodiment of the present invention; Figure 5 Shown Figure 4 The left-view structure; Figure 6 A set of lifting rail assembly lifting structures according to an embodiment of the present invention is shown; Figure 7 Shown Figure 6 The left-view structure; Figure 8 It shows the stress state of the sintering car trolley when a group of lifting rail assemblies according to an embodiment of the present invention are lifted; Figure 9 It shows the operating state of a sintering car trolley when a set of lifting rail assemblies according to an embodiment of the present invention is lifted; Figure 10 shows a first track structure according to an embodiment of the invention; Figure 11 A second track structure according to an embodiment of the present invention is shown.

[0048] like Figures 1 to 11 As shown together, the present invention provides a device for eliminating arching and deviation of a sintering machine trolley, and the two ends of the sintering machine trolley respectively run along two corresponding trolley running rails, and the device for eliminating arching and deviation is arranged at positions corresponding to the two trolley running rails, and the device for eliminating arching and deviation includes two groups of lifting rail assemblies 1 respectively connected to the two trolley running rails, and a power system 2 that provides power for the two groups of lifting rail assemblies, wherein the power system 2 includes two power devices respectively corresponding to the two groups of lifting rail assemblies, and each power device corresponds to a group of lifting rail assemblies; each group of lifting rail assemblies includes a first rail located in the middle position and a second rail respectively arranged at both ends of the first rail, and the first rail is interconnected with the second rails respectively at both ends, and each power device is connected to the first rail of each group of lifting rail assemblies; the first rail of each group of rail assemblies drives the second rails at both ends of the first rail to rise and fall under the action of the corresponding power device, so as to achieve the elimination of arching or deviation of the sintering machine trolley.

[0049] exist Figure 1 and Figure 2 In the illustrated embodiment, the sintering machine trolley's arching and skewing elimination device is located on the return track beneath the sintering machine's central frame, near the rear of the machine. The arching and skewing elimination device includes two sets of lifting track assemblies, a power system, and a management system for controlling the power system's raising and lowering of the two sets of lifting track assemblies.

[0050] Two sets of lifting rail assemblies are respectively installed at both ends of the sintering machine trolley along the corresponding two trolley running tracks. Each lifting rail assembly includes three sections of rails: a first rail 11 and two second rails 12. The first rail 11 is located in the middle, and the second rails 12 are connected to the two ends of the first rail 11.

[0051] Furthermore, the two lifting track assemblies 1 are respectively connected to the corresponding trolley running tracks 5 by means of hinges. The first track 11 in each lifting track assembly 1 is respectively connected to the two second tracks 12 by means of hinges.

[0052] exist Figure 10 and Figure 11 In the illustrated embodiment, the first track 11 includes a first track bracket 111 and a first track body 112. The first track bracket 111 is welded from I-beams, and the first track body 112 is welded from 50Mn square steel and Q235 steel plates. The power unit is mounted below the first track bracket.

[0053] The second track 12 includes a second track bracket 121 and a second track body 122, wherein the second track bracket 121 is welded by two vertical plates, and the second track body 122 is welded by 50Mn square steel and Q235 steel plate; the second track is connected to the trolley running track through the two vertical plates.

[0054] In an embodiment of the present invention, the lifting track assembly comprises two sections of the second track and one section of the first track. The lifting track assembly is connected to the trolley running track via an articulated connection. A slotted hole is provided on the trolley running track at the articulated connection to accommodate the lifting motion of the lifting track assembly. The supporting beam uprights of the trolley running track are inserted between the two uprights.

[0055] Power system 2 includes a PCL system and two power units (a first power unit 21 and a second power unit 22). Specifically, one power unit corresponds to a set of lift rail assemblies, and one power unit provides thrust for each set of lift rail assemblies. The power units are located below the first rail of the corresponding lift rail assembly. When the power units provide power to the first rail, the first rail 11 drives the connected second rail 12 upwards.

[0056] exist Figures 3 to 5 In the illustrated embodiment, when the two power devices of the power system act on the corresponding lifting rail assemblies simultaneously, the two sets of lifting rail assemblies are lifted simultaneously to form arched rails to eliminate the arching of the sintering machine trolley.

[0057] like Figure 3As shown in the figure, the sintering machine trolley is in an arched state. When the device is not started, the front end of the rear trolley contacts it and squeezes it tightly, preventing it from falling onto the trolley running track. Each trolley will go through this process, causing the trolley on the return track to have a shoulder-over-arching phenomenon.

[0058] like Figure 4 and Figure 5 As shown, the device for eliminating arching and deviation is activated. The power system simultaneously raises the two sets of lifting track components to form an arched track, which causes the sintering machine arching trolley to lift the front wheels, shortening the height difference between them and the rear wheels. The trolley then slowly moves off the track, reducing the height difference between the front and rear wheels. The trolley goes through three stages: uphill operation, horizontal operation, and downhill operation, eliminating friction between the trolleys and thus eliminating the arching phenomenon of the trolley. After the arching phenomenon is eliminated, the power system of this device returns to its initial height, and the two sets of lifting track components descend to a horizontal height, allowing the sintering machine trolley to operate smoothly according to the original design.

[0059] Among them, when the management system determines that the trolley is in an arched state, the arch and deviation elimination device can receive instructions from the PLC system to start the device to eliminate the arch. After the management system determines that the arch state disappears, it receives instructions to restore the initial state.

[0060] exist Figures 6 to 9 In the illustrated embodiment, when a power unit of the power system acts on a corresponding lifting track assembly, the lifting track assembly corresponding to the power unit is lifted, causing the sintering machine trolley to tilt in the horizontal direction. The combined force formed by the driving force of the sintering machine trolley in the tilted state and the gravity eliminates the deviation of the sintering machine trolley.

[0061] like Figure 6 、 Figure 7 As shown, the sintering machine trolley is in a deviation state, and the arching and deviation elimination device of the sintering machine trolley is started. The lifting track component corresponding to the deviation state is raised by the power system to form a single-sided arched track, so that a height difference is formed on both sides of the sintering machine trolley. Under the combined force of the gravity component and the sintering machine driving force, the sintering machine trolley eliminates the deviation phenomenon.

[0062] like Figure 8 As shown in the figure, the resultant force on the sintering machine trolley at the point where a set of lifting rail components is raised is as follows: Figure 9 As shown in the figure, after the sintering machine trolley passes through this set of lifting rail components, the sintering machine trolley gradually eliminates the deviation phenomenon. After the deviation phenomenon is eliminated, the power system of the device returns to its initial height, and the lifting rail components are lowered to the horizontal height, allowing the sintering machine trolley to operate smoothly according to the original design.

[0063] In an embodiment of the present invention, when the management system determines that the trolley is in a deviation state, the device can receive instructions from the PLC system to start the device to eliminate the deviation. After the management system determines that the deviation state disappears, the device receives instructions to restore the initial state.

[0064] In the embodiment of the present invention, the power device is a hydraulic cylinder or a pneumatic cylinder, but is not limited to this device. In specific applications, a suitable device is selected according to actual needs to provide power for the lifting track assembly.

[0065] In this embodiment of the present invention, the power system provides thrust to synchronously elevate the two lift rail assemblies, creating a curved track to eliminate arching of the sintering machine trolley. Propelling the single or double lift rail assembly tilts the sintering machine trolley horizontally, eliminating deviations due to the combined force of the sintering machine's thrust and gravity. After the arching or deviation is eliminated, the power system restores the two lift rail assemblies to a horizontal position, allowing the sintering machine trolley to operate smoothly according to its original design.

[0066] If the device includes a management system, the PLC system of the power system has a data transmission interface that can communicate with the management system and receive instructions from the management system. When the management system determines that the sintering machine trolley is arching or deviating, the device can be operated to eliminate the arching or deviating of the sintering machine trolley.

[0067] It can be seen from the above embodiments that the device for eliminating arching and deviation of a sintering machine trolley provided by the present invention can eliminate the arching of the sintering machine trolley by simultaneously pushing two sets of lifting rail assemblies up and down through a power system; a set of lifting rail assemblies is pushed up and down by a power device in the power system, so that the sintering machine trolley is tilted in the horizontal direction, and the deviation of the sintering machine trolley is eliminated by relying on the combined force formed by the driving force of the sintering machine and gravity; the present invention can solve the problem of arching or deviation of the sintering machine trolley at the same time through the interaction between the power system and the two sets of lifting rail assemblies.

[0068] The above description of the device for eliminating camber and deviation of a sintering machine trolley according to the present invention is described by way of example with reference to the accompanying drawings. However, those skilled in the art will appreciate that various improvements may be made to the device for eliminating camber and deviation of a sintering machine trolley according to the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
