Description

Technical Field

[0001] This utility model relates to the field of sintering machine trolley technology, and in particular to a trolley with quick grate bar replacement. Background Technology

[0002] Currently, belt sintering machines are commonly used in domestic sintering plants. The trolley, as the core component of the sintering machine, plays a crucial role in production. As the trolley is a material carrier, it is in contact with high-temperature materials for a long time, which makes the equipment prone to damage. In particular, the grate bars are in direct contact with the materials. Some sintering plants have to replace some of the grate bars every three months or so.

[0003] Typically, in a trolley structure, each trolley beam has a dozen or so heat insulation components, and each trolley beam has hundreds of grate bars outside the heat insulation components. Each trolley weighs around 10 tons. During sintering machine operation, adjacent trolleys are pressed against each other, and the crane can only reach the middle of the sintering machine with sufficient space. When replacing grate bars, the sintering machine must be cleaned and stopped. The tail hydraulic device must be activated to open the tail assembly, creating a gap between the upper trolleys. The trolley is then lifted to the maintenance area, and the grate bars are removed one by one from one side of the trolley beam. When replacing heat insulation components, the side panels must be removed, and the components are removed one by one from one side of the trolley beam. After removal, the process is reversed to replace the grate bars or heat insulation components. The trolley is then installed back onto the sintering machine, and the tail hydraulic device is released, completing one replacement cycle. This method results in a long replacement cycle for the trolley structure's grate bars or heat insulation components, requiring the sintering machine to be shut down for extended periods, disrupting normal production.

[0004] Therefore, it is necessary to propose a quick-change grate trolley to solve or at least alleviate the above-mentioned defects. Utility Model Content

A plurality of connecting ribs arranged in a horizontal direction are connected between the trolley connecting parts of each two adjacent heat insulation beams. A plurality of grate bars arranged in a horizontal direction are connected between the grate bar mounting parts of each two adjacent heat insulation beams.

[0009] The positioning assembly includes two positioning units arranged laterally opposite each other. The positioning units are detachably connected to the guardrail, and one end of the positioning unit stops above the grate bar.

[0031] Please see the appendix Figure 1-2 This utility model provides a quick-change grate bar 40 trolley in one embodiment, comprising a heat insulation component 10, a trolley mechanism 20, a positioning component 30, and multiple grate bars 40. First, it should be noted that in this application, "longitudinal" refers to the extension direction of the trolley, and "lateral" refers to the width direction of the trolley; please refer to the accompanying drawings for details. Unlike the prior art, where replacing heat insulation requires removing the side panels 220 and then dismantling them one by one from one side of the trolley beam 211, and then reversing the above sequence to replace the grate bars 40 or heat insulation before installing the trolley onto the sintering machine and releasing the tail hydraulic device to complete one replacement, this method results in a long replacement cycle for the trolley structure grate bars 40 or heat insulation, requiring the sintering machine to be shut down for extended periods, affecting normal production. This application solves the above-mentioned defects in the prior art by providing a quick-change grate bar 40 trolley, as detailed below:

[0032] The trolley mechanism 20 includes a trolley body 210 and two side panels 220 connected laterally to both sides of the trolley body 210. The heat insulation component 10 includes multiple heat insulation beams 110 and connecting ribs 120 arranged longitudinally at intervals. Each heat insulation beam 110 includes a trolley connecting part 111 and a grate mounting part 112 arranged sequentially from bottom to top. The trolley connecting part 111 is connected to the trolley body 210. Multiple connecting ribs 120 arranged laterally are connected between the trolley connecting parts 111 of each adjacent two heat insulation beams 110. Multiple grate bars 40 arranged laterally are connected between the grate mounting parts 112 of each adjacent two heat insulation beams 110. The positioning component 30 includes two positioning units arranged laterally opposite each other. The positioning units are detachably connected to the side panels 220, and one end of the positioning unit stops above the grate bars 40.

[0033] Specifically, the quick-change grate bar 40 trolley in this application includes a heat insulation component 10, a trolley mechanism 20, a positioning component 30, and multiple grate bars 40. The trolley mechanism 20 is a common structural form of sintering machine trolleys, typically including a trolley body 210 and side rails 220 arranged on both sides of the trolley body 210. The trolley body 210 includes multiple trolley beams 211 arranged longitudinally at intervals (including trolley wheels and other components well known to those skilled in the art, so they will not be described in detail here). The heat insulation component 10 is installed on the trolley beams 211 and then the grate bars are installed, so that the sintered ore is placed between the grate bars 40 and the side rails 220, and the sintering trolley transports and unloads the material.

[0034] The heat insulation component 10 includes multiple longitudinally spaced heat insulation beams 110 and connecting ribs 120. The heat insulation beams 110 differ from traditional heat insulation beam structures; in this application, they are configured as a two-section structure, comprising a trolley connecting part 111 and a grate mounting part 112 arranged sequentially from bottom to top. The trolley connecting part 111 is used for installation and connection to the top of the trolley beam 211, and also for installation and connection of the connecting ribs 120. Typically, each trolley beam 211 is connected to one heat insulation beam 110. 10. By processing the connecting ribs 120, multiple heat insulation beams 110 are connected as a whole, so that the connecting ribs 120 connect the trolley connection portions 111 of each pair of adjacent heat insulation beams 110. This allows for disassembly and replacement of the entire heat insulation assembly 10, eliminating the need to disassemble the entire trolley and then remove the heat insulation components and grate. It is worth noting that the connecting ribs 120 between the trolley connection portions 111 of two heat insulation beams 110 can be multiple ribs arranged side-by-side in a transverse direction. To avoid structural instability due to excessively long spans, a multi-piece splicing method can be used, which also facilitates processing. Preferably, the connecting ribs 120 are connected to the trolley connecting part 111 by welding, which makes processing convenient and ensures a good connection and fastening effect. In this application, the grate plate is installed on the grate bar mounting part 112, so that each pair of adjacent heat insulation beams 110 grate bar mounting parts 112 is connected by the grate bar 40 (similar to the connecting beam, each pair of adjacent heat insulation beams 110 grate bar 40 is connected by the grate bar 40). The installation sections 112 also adopt a pattern of multiple horizontally arranged side by side. In this way, whether installing or removing, the heat insulation beam 110 and the grate 40 can be installed / removed together in one piece, which greatly improves efficiency. Moreover, the grate 40 can be installed on the heat insulation beam 110 before installation, and then the entire heat insulation component 10, together with the grate 40 installed above, can be lifted and installed on the trolley body 210. Replacement is simple and quick. The sintering machine does not need to be cleaned. Replacement can be completed with only a short stop, which can greatly improve production efficiency.

[0035] Furthermore, the positioning component 30 is used to fix the installation of the grate bar 40. It includes two positioning units arranged laterally opposite each other so that the positioning effect is achieved on both sides at the same time. The positioning unit is set close to the top of the grate bar 40 so as to stop (press) the grate bar 40 downward. While pressing the grate bar 40, the heat insulation beam 110 can also be fixed and restricted under the action of the grate bar 40. The positioning effect is obvious. When disassembling the heat insulation beam 110 and the grate bar 40, only the positioning component 30 needs to be disassembled.

[0036] It is worth mentioning that the size of the internal heat insulation beam 110 can be set to be larger than that of the heat insulation beams 110 on both sides. Since the trolley beam 211 in the trolley body 210 is usually smaller on both sides and larger inside, this is to match the size of the trolley beam 211 in the trolley body 210. In another preferred embodiment, the internal heat insulation beam 110 can also be set to include two oppositely arranged heat insulation half beams. The structure formed by the two heat insulation half beams enclosing and arranging side by side is similar to the cross-sectional shape of the heat insulation beams 110 on both sides (each side has a groove, and the bottom forms a U-shaped opening after being arranged side by side). This makes it easier to process and adapt to different sizes of trolley beam 211.

[0037] In a preferred embodiment of the present invention, the trolley connecting part 111 is U-shaped with the opening facing downwards, and the trolley connecting part 111 is engaged with the trolley beam 211.

[0038] It should be noted that the U-shape with the opening facing downwards allows the trolley connection 111 to be upside down on the trolley beam 211 for a snap-fit ​​connection. In this special U-shaped structure, the trolley beam 211 can limit the horizontal movement of the heat insulation beam 110 and the grate bar 40.

[0039] In a preferred embodiment of the present invention, the width of the trolley connecting part 111 and the grate bar mounting part 112 are the same, and a groove for placing the support legs of the grate bar 40 is formed between the trolley connecting part 111 and the grate bar mounting part 112.

[0040] It is worth noting that the trolley connecting part 111 and the grate bar mounting part 112 have the same width, which facilitates the stable installation of the grate bar 40 and makes it easy to process and form a groove. Since the grate bar 40 usually has legs at both ends along the longitudinal direction, the groove is used to place the legs of the grate bar 40. At the same time, the structural characteristics between the groove and the legs can restrict longitudinal movement.

[0041] In a preferred embodiment of this utility model, the positioning unit is a locking pin 310, and the guard plate 220 has a locking pin 310 mounting hole. The locking pin 310 mounting hole is located near the top of the grate bar 40, and the locking pin 310 is connected to the locking pin 310 mounting hole to stop above the grate bar 40.

[0042] It is worth noting that the locking pin 310 is easy to install and disassemble, which saves on the operation process. It can be quickly assembled through the matching locking pin 310 mounting hole, and the tightness after installation is good. The end of the locking pin 310 extending out of the mounting hole achieves a good positioning and restriction effect to stop above the grate bar 40, while the locking pins 310 on both sides simultaneously position the grate bar 40 on both sides.

[0043] Furthermore, there are multiple positioning components 30, and the multiple positioning components 30 are arranged at intervals along the longitudinal direction.

[0044] It should be noted that, considering that the multiple grate bars 40 are connected to the heat insulation component 10 with a certain longitudinal length, in order to ensure a better positioning effect, the positioning component 30 is set in the form of multiple longitudinally spaced components, so that the positioning performance is evenly distributed.

[0045] Furthermore, the grate bar mounting portion 112 is provided with arc-shaped chamfers on both sides along the transverse direction.

[0046] It should be understood that using a rounded chamfer allows the grate bar 40 to make smooth contact during installation on the grate bar mounting part 112, avoiding wear on the grate bar 40 and thus preventing mutual damage, thereby improving the service life of the grate bar 40 and the grate bar mounting part 112.

[0047] Furthermore, gaps are reserved between the grate bar 40 and the side wall of the grate bar mounting part 112, and between the support leg of the grate bar 40 and the bottom side of the grate bar mounting part 112.

[0048] It should be noted that this can improve the heat insulation effect at the connection between the grate bar 40 and the grate bar mounting part 112, thereby improving the heat insulation performance of the heat insulation component 10. Similarly, the gap reserved between the trolley connection part 111 and the trolley beam 211 can also improve the heat insulation performance at the trolley connection. The specific gap value can be preset by those skilled in the art when processing the heat insulation beam 110 structure according to actual needs.

[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.
