Description

Technical Field

[0001] This utility model relates to the field of sintering machine technology, and in particular to a tail bend of a sintering machine. Background Technology

[0002] The sintering machine is the main equipment in the sintering process. Currently, the tail unloading area mainly relies on the cooperation of the tail star wheel and the tail curve to make the sintering trolley move from top to bottom along the tail curve, thereby realizing the material unloading process and the trolley's cyclic movement.

[0003] The existing tail curve structure consists of several supports on the tail moving frame for installing and supporting the inner and outer rails. The outer rails are equipped with adjustment seats to adjust the gap between the inner and outer rails during installation. Because each support is subjected to force independently, the overall rigidity of the tail curve is limited. During equipment operation, support deformation and rail position displacement are likely to occur, affecting the stable operation of the equipment and causing a series of problems such as the trolley arching.

[0004] Therefore, it is necessary to propose a tail bend in the sintering machine to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0005] The main purpose of this invention is to provide a tail bend in a sintering machine to solve the problem in the prior art where the track support is subjected to force alone, resulting in limited overall rigidity and easy deformation.

[0006] To achieve the above objectives, this utility model provides a tail curve for a sintering machine, comprising two tail track units arranged laterally opposite each other. Each tail track unit includes a frame, an outer track assembly, and an inner track assembly; wherein,

[0007] The outer rail assembly includes an outer ring beam, an outer support seat assembly, and an outer track. The inner rail assembly includes an inner ring beam, an inner support seat assembly, and an inner track.

[0009] The outer track is adjustable in the lateral direction and in the direction toward the inner track, respectively. The inner track is adjustable in the lateral direction. The space between the outer track and the inner track is used to define the running trajectory of the trolley wheels.

[0010] Preferably, the outer support assembly includes a plurality of outer support seats, which are spaced apart along the extension direction of the outer track and connected to the inner side of the outer ring beam.

[0011] Preferably, the inner support assembly includes a plurality of inner support seats, which are spaced apart along the extension direction of the inner track and connected to the outer side of the inner ring beam.

[0012] Preferably, each track unit further includes an adjusting shim, with at least one adjusting shim connected between the outer track and the outer support seat, and between the outer track and the outer ring beam, and at least one adjusting shim connected between the inner track and the inner support seat.

[0013] Preferably, bolt holes are provided on the outer support and the inner support respectively, the outer track is connected to the outer support by bolts, and the inner track is connected to the inner support by bolts.

[0014] Preferably, the bolt holes on the outer support are elongated holes that extend along the length of the outer support.

[0017] Preferably, both the outer support and the inner support have two bolt holes.

[0018] Preferably, both the outer ring beam and the inner ring beam are welded to the frame.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention provides a tail curve for a sintering machine, comprising two tail track units arranged laterally opposite each other. Each tail track unit includes a frame, an outer track assembly, and an inner track assembly. The outer track assembly includes an outer ring beam, an outer support seat assembly, and an outer track. The inner track assembly includes an inner ring beam, an inner support seat assembly, and an inner track.

[0032] Please see the appendix Figure 1-3This utility model provides an embodiment of a sintering machine tail curve, comprising two tail track units arranged laterally opposite each other. Each tail track unit includes a frame 10, an outer track assembly 20, and an inner track assembly 30. First, it should be noted that "lateral" in this application refers to the width direction along the trolley 40, as shown in the accompanying drawings. Unlike existing technologies where each support is individually stressed, resulting in limited overall stiffness of the tail curve and potential issues such as support deformation and track position shifting during equipment operation, which affect stable operation and cause the trolley 40 to arch, this application addresses these shortcomings by providing a tail curve for the sintering machine, as detailed below:

[0033] The outer rail assembly 20 includes an outer ring beam 210, an outer support seat assembly 220, and an outer track 230. The inner rail assembly 30 includes an inner ring beam 310, an inner support seat assembly 320, and an inner track 330. Both the outer ring beam 210 and the inner ring beam 310 are connected to the frame 10, and the inner ring beams 310 are spaced apart and positioned inside the outer ring beam 210. The outer support seat assembly 220 is connected to the inner side of the outer ring beam 210, and the outer track... 230 is connected to the outer support seat assembly 220, the inner support seat assembly 320 is connected to the outer side of the inner ring beam 310, and the inner track 330 is connected to the inner support seat assembly 320; the outer track 230 is adjustable in the lateral direction and in the direction toward the inner track 330, the inner track 330 is adjustable in the lateral direction, and the space between the outer track 230 and the inner track 330 is used to define the running trajectory of the trolley 40 wheels.

[0034] Specifically, the tail curve of the sintering machine in this application includes two tail track units arranged laterally opposite each other, so that the trolley 40 can travel between the two tail track units. Each tail track unit includes a frame 10, an outer track assembly 20, and an inner track assembly 30. The frame 10 is used for the installation and connection of the outer track assembly 20 and the inner track assembly 30. The outer track assembly 20 and the inner track assembly 30 are spaced apart to form a track gap space for the trolley 40 to run. The outer track assembly 20 and the inner track assembly 30 have corresponding structural shapes, that is, they are the same shape but different in size, so as to ensure that the track gap space formed by the interval is normal in shape.

[0035] The outer rail assembly 20 includes an outer ring beam 210, an outer support seat assembly 220, and an outer track 230. The inner rail assembly 30 includes an inner ring beam 310, an inner support seat assembly 320, and an inner track 330. The outer ring beam 210 and the inner ring beam 310 are made of steel profiles, which have high strength and rigidity and can be welded to the frame 10 for stable connection. By connecting the outer support seat assembly 220 and the inner support seat assembly 320 respectively, the traditional stress distribution of individual supports can be transformed into a unified stress distribution between the support and the ring beam, improving the overall structural rigidity. The track has better stability after being installed on the support base, which better compensates for the defect of easy deformation of the curved structure. It can be understood that the outer support base assembly 220 is connected to the inner side of the outer ring beam 210 (the side closer to the inner ring beam 310), and the inner support base assembly 320 is connected to the outer side of the inner ring beam 310 (the side closer to the outer ring beam 210). This allows the outer track 230 and the inner track 330 to be installed separately and form a track gap space between them, which is used for the installation and travel of the trolley 40 wheels to limit the wheel running trajectory. The wheels on both sides of the trolley 40 are respectively connected to the track gap space of the two rear track units.

[0036] Furthermore, the outer track 230 is laterally adjustable to adjust its lateral position, thereby adjusting the spacing (track gap) between the outer tracks 230 of the two tail track units to ensure the relative position between the track and the wheel. The outer track 230 is also adjustable towards the inner track 330, thereby adjusting the spacing between the outer track 230 and the inner track 330 in each tail track unit to adjust the relative position between the wheels of the trolley 40 and the track, accommodating wheel installation. The laterally adjustable inner track 330 is used to adjust its lateral position, thereby adjusting the spacing (track gap) between the inner tracks 330 of the two tail track units to match the outer track and maintain consistent track gap adjustment between the two tail track units, thus facilitating the connection of the trolley 40.

[0037] In a preferred embodiment of the present invention, the outer support assembly 220 includes a plurality of outer support seats 221, which are arranged at intervals along the extension direction of the outer track 230 and connected to the inner side of the outer ring beam 210.

[0038] It should be noted that by setting multiple spaced outer support seats 221 to ensure that the outer support seats 221 are evenly distributed, the outer track 230 has more connection nodes when connected, and the connection stability is better. In addition, the outer ring beam 210 improves the overall connection, so as to ensure sufficient rigidity as support for the curved structure and avoid deformation and arching.

[0039] In a preferred embodiment of the present invention, the inner support seat assembly 320 includes a plurality of inner support seats 321, which are arranged at intervals along the extension direction of the inner track 330 and connected to the outer side of the inner ring beam 310.

[0040] It should be noted that, similar to the outer support seat 221, multiple spaced inner support seats 321 are set to ensure that the inner support seats 321 are evenly distributed. In this way, the more connection nodes the inner track 330 has, the better the connection stability will be. At the same time, the inner ring beam 310 is used to improve the connection stability and ensure sufficient rigidity.

[0041] In a preferred embodiment of the present invention, each track unit further includes an adjusting shim 240. At least one adjusting shim 240 is connected between the outer track 230 and the outer support 221, and between the outer track 230 and the outer ring beam 210. At least one adjusting shim 240 is connected between the inner track 330 and the inner support 321.

[0042] It is worth noting that the position of the track can be adjusted by setting adjustment shims 240. This method is convenient to operate, and the number of adjustment shims 240 can be selected according to actual needs. Specifically, adjustment shims 240 are set between the outer track 230 and the outer support 221 to adjust the lateral position of the outer track 230, thereby adjusting the spacing between the outer tracks 230 of the two tail track units; adjustment shims 240 are set between the outer track 230 and the outer ring beam 210 to adjust the position of the outer track 230 in the direction towards the inner track 330, thereby adjusting the outer track position. The spacing between track 230 and inner track 330; it should be noted that, in order to facilitate uniform adjustment, the inner track 330 does not need to be adjusted in the direction towards the outer track 230. It remains stationary and the outer track 230 can be adjusted by adding or removing shims 240. The inner track 330 only needs to have its lateral position adjusted by adding or removing shims 240 between it and the inner support 321, so as to keep the spacing between the outer tracks 230 and the two tail track units consistent, ensuring that the outer track 230 and inner track 330 are kept in the same plane in a tail track unit.

[0043] In a preferred embodiment of this utility model, bolt holes are respectively provided on the outer support 221 and the inner support 321. The outer track 230 is connected to the outer support 221 by bolts, and the inner track 330 is connected to the inner support 321 by bolts.

[0044] It is worth noting that the bolted connection facilitates the installation of the outer support 221 and the inner support 321, making operation convenient and allowing for easy maintenance and replacement later. Preferably, to ensure stable connection, both the outer support 221 and the inner support 321 have two bolt holes. Those skilled in the art can set this according to actual needs. It is understood that if an adjusting shim 240 is added, a corresponding bolt hole should also be made on the corresponding adjusting shim 240 so that the bolt can pass through the adjusting shim 240 simultaneously.

[0045] Furthermore, the bolt holes on the outer support 221 are elongated holes, which extend along the length of the outer support 221.

[0046] It should be noted that in curved structures, the forces on the outer track 230 are usually different from those on the inner track 330. In curves with small radii, the deflection and beam end rotation of the outer track 230 are usually greater than those of the inner track 330, exhibiting a more pronounced bending-torsional effect. Therefore, when the outer track 230 is bolted onto the outer support 221, it uses elongated holes to cooperate with adjusting shims 240 to adjust the gap between the inner and outer tracks, thereby preventing rigid failure of the outer track 230 connection. Furthermore, the bolt holes on the inner support 321 are round holes, which can be used to maintain a fixed connection.

[0047] Furthermore, both the inner track 330 and the outer track 230 are U-shaped tracks, each comprising a semicircular segment and a straight segment. The inner track 330 has two inner support seats 321 at the apex of the semicircular segment and near the two semicircular endpoints.

[0048] It should be noted that in the tail curve structure, the track is usually U-shaped, and the U-shaped structure is usually composed of a semicircular segment and a straight segment. In the semicircular segment, considering the stress at the arc apex and the connection point of the two semicircular ends, the structural deformation is relatively large. Therefore, in the semicircular segment of the inner track 330, inner support seats 321 are added at the arc apex and near the two semicircular ends. In a preferred embodiment of this application, the number of these locations can be set to two inner support seats 321 side by side. Simultaneously, in the semicircular segment of the outer track 230, two outer support seats 221 can also be set side by side at the arc apex and near the two semicircular ends. Furthermore, since the semicircular arc of the outer track 230 is larger than that of the inner track 330, two more outer support seats 221 can be added at the central position between the arc apex and the semicircular ends of the outer track 230 to improve the structural rigidity and connection stability. Please refer to the appendix for details. Figure 1 .

[0049] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
