[0002] The sintering machine trolley is the main operating component of the sintering machine. It forms a rotating chain between the head and tail wheels of the sintering machine and carries an important component of the entire sintering production line, which is crucial to the stable operation of the sintering process.

[0003] The main components of a sintering machine trolley include the trolley body, end caps, side rails, grate bars, heat insulation components, wheels, and axles. The grate bars support and separate the materials, allowing air to pass evenly through the material layer and promoting the sintering process. The heat insulation components reduce heat loss and improve the trolley's heat resistance. The grate bars and heat insulation components are consumable parts; replacing them requires removing the side rails on both sides of the trolley, which is difficult and time-consuming. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a sintering machine trolley structure that facilitates the replacement of heat insulation components and furnace grate bars.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a sintering machine trolley structure that facilitates the replacement of heat insulation components and grate bars, including a heat insulation component base and a heat insulation component. The heat insulation component base is provided with an end heat insulation seat and a middle heat insulation seat. The heat insulation component is provided with a groove adapted to the middle heat insulation seat. The opening width of the groove is greater than the width of the end heat insulation seat. The heat insulation component is fixed to the end heat insulation seat by a positioning component. The gap between the end heat insulation seat and the trolley side plate can accommodate at least one grate bar.

[0006] As a further improvement of this utility model: a first limiting hole is provided on the side of the end heat insulation seat, and a second limiting hole is provided on the side of the heat insulation component located on the end heat insulation seat. The first limiting hole and the second limiting hole are connected, and a positioning component is inserted through the first limiting hole and the second limiting hole.

[0007] The base of the heat insulation component has end heat insulation seats at both ends, and the width of the end heat insulation seats is smaller than the width of the middle heat insulation seat.

[0008] As a further improvement of this utility model: at least two first limiting holes are provided along the length direction of the end heat insulation seat, and at least two second limiting holes are provided along the length direction of the heat insulation component.

[0009] As a further improvement of this utility model: the first limiting hole and the second limiting hole are through holes.

[0015] As a further improvement of this utility model: several of the heat insulation components are arranged on the heat insulation component base.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0026] like Figures 1 to 2 As shown in the figure, this utility model embodiment discloses a sintering machine trolley structure that facilitates the replacement of heat insulation components and grate bars. It includes a heat insulation component base 3 and a heat insulation component 2. The heat insulation component base 3 is provided with an end heat insulation seat 31 and a middle heat insulation seat 32. The width of the end heat insulation seat 31 is smaller than the width of the middle heat insulation seat 32. The heat insulation component 2 is provided with a groove that adapts to the middle heat insulation seat 32. The opening width of the groove is larger than the width of the end heat insulation seat 31. The heat insulation component 2 is fixed to the end heat insulation seat 31 by a positioning component 5. The gap between the end heat insulation seat 31 and the trolley side plate 4 can accommodate at least one grate bar 1.

[0027] It is necessary to understand the original sintering machine trolley structure, such as... Figure 3 and Figure 4 As shown, the ends and middle of the heat insulation base 3 are set with the same width. The original slot-type installation specifically involved the trolley heat insulation 2 having a groove-shaped structure and the heat insulation base 3 being T-shaped. When installing the heat insulation, the end plate 4 of the trolley needed to be removed and then inserted from the end. This structure was not conducive to the replacement of the grate bars 1 and the heat insulation 2.

[0028] To facilitate the installation of the grate bars 1 and the heat insulation component 2, this embodiment changes the structural form of the heat insulation component at the end of the trolley and its installation on the trolley, eliminating the original slot-type installation and adopting a pin-type installation. For example... Figure 1 and Figure 2 As shown, the width of the end of the heat insulation base 3 is reduced, and the width of the end heat insulation seat 31 is smaller than the groove opening of the heat insulation 2, so that the heat insulation 2 can be placed on the heat insulation base 3 from above and then fixed by the positioning part 5. There is a certain gap between the end heat insulation seat 31 and the trolley sideboard 4, so the heat insulation 2 can be smoothly placed on the end heat insulation 2 from above without removing the trolley sideboard 4. The grate bars 1 and the heat insulation 2 in the middle area can be replaced by moving in and out from the end of the heat insulation base 3. After the heat insulation 2 in the end area is fixedly connected to the end heat insulation seat 31, the grate bars 1 at the end can be inserted into the gap between the end heat insulation seat 31 and the trolley sideboard 4 to complete the replacement.

[0029] The structures of the heat insulation component 2 and the grate bar 1 do not need to be changed. The limiting part of the heat insulation component 2 at the end can be retained. This limiting part is locked onto the bottom side of the middle heat insulation seat 32. The groove of the heat insulation component 2 is similar to an inverted U-shaped groove. The legs of the grate bar 1 are locked below the limiting part of the heat insulation component 2. The width of both sides of the end heat insulation seat 31 is reduced, and the original sleeve installation method of the heat insulation component 2 is eliminated. The improved sintering trolley structure facilitates the installation of the grate bar 1 and the heat insulation component 2, shortens the replacement time, reduces labor intensity, and saves labor.

[0030] The heat insulation base 3 has end heat insulation seats 31 at both ends. Usually, limiting holes are opened on the side of the heat insulation 2 and the end heat insulation seat 31, and the positioning member 5 is inserted to fix the end heat insulation 2 on the end heat insulation seat 31.

[0031] Furthermore, a first limiting hole is provided on the side of the end heat insulation seat 31, and a second limiting hole is provided on the side of the heat insulation component 2 located on the end heat insulation seat 31. The first limiting hole and the second limiting hole are connected, and a positioning component 5 is provided in the first limiting hole and the second limiting hole. The positioning component 5 is a locking pin.

[0032] In some embodiments, at least two first limiting holes are provided along the length direction of the end heat insulation seat 31, and at least two second limiting holes are provided along the length direction of the heat insulation member 2.

[0033] A number of heat insulation components are arranged along the length of the heat insulation base 3. A grate bar is installed on the upper layer of the heat insulation components. The heat insulation base 3 is placed vertically in a T-shape, as shown in the figure. Two first limiting holes are opened on the side of the end heat insulation base 31 along the length direction. Correspondingly, the heat insulation component 2 also has two second limiting holes that communicate with the first limiting holes. The heat insulation component 2 is fixed on the heat insulation base 3 by inserting the positioning component 5.

[0034] In some embodiments, the first limiting hole and the second limiting hole are through-hole structures.

[0035] Limiting holes are made on the sides of the heat insulation component 2 and the heat insulation component base 3, preferably through holes. Of course, a second limiting hole in the form of a through hole can also be made on the side of the heat insulation component 2, and a first limiting hole in the form of a non-through hole can be made on the side of the heat insulation component base 3. It is only necessary to ensure that the heat insulation component 2 can be reliably fixed on the heat insulation component base 3 after the positioning component 5 is inserted into the second limiting hole and the first limiting hole in sequence.

[0036] In some embodiments, the length of the end heat insulation seat 31 is greater than or equal to the length of a heat insulation element 2.

[0037] The length of the end heat insulation seat 31 is designed to accommodate at least one heat insulation component 2 to be lifted upwards and placed downwards, which facilitates the installation of the heat insulation component 2 and ensures that the structural changes of the heat insulation component base 3 are minimal.

[0038] In some embodiments, the first limiting hole is formed at the top of the end heat insulation seat 31, and the second limiting hole is formed at the top of the heat insulation member 2.

[0039] The positions of the first limiting hole and the second limiting hole can also be changed, that is, a fixed connection can be set on the top of the heat insulation component 2 and the heat insulation component base 3.

[0040] Furthermore, the second limiting hole is a countersunk structure, and the lower side of the first limiting hole away from the heat insulation component 2 is a closed surface. The first and second limiting holes are located on the side closer to the grate bars. It is advisable to design the second limiting hole as a countersunk structure. After the positioning component 5 is inserted into the second limiting hole and the first limiting hole in sequence, the end of the positioning component 5 is lower than the top end face of the heat insulation component 2, which does not affect the installation of the grate bars.

[0041] Furthermore, in order to facilitate the smooth removal of the positioning part 5, a limiting groove can be opened on the top of the heat insulation part 2, and the end of the positioning part 5 has a positioning part that is adapted to the limiting groove. The positioning part is embedded in the limiting groove so that the positioning part 5 is lower than the top end face of the heat insulation part 2, which does not affect the installation of the grate bars.

[0042] In some embodiments, the second limiting hole on the heat insulation member 2 located on the end heat insulation seat 31 is integrally formed with the positioning member 5, and the lower end of the positioning member 5 is inserted into the first limiting hole of the end heat insulation seat 31.

[0043] The heat insulation component 2 at the end is integrated into the positioning component 5. When the heat insulation component 2 is placed downwards on the heat insulation component base 3, the positioning component 5 is precisely embedded in the first limiting hole at the top. When replacing the heat insulation component 2 and the grate bars, the heat insulation component 2 is lifted, and the positioning component 5 is also smoothly pulled out from the first limiting hole. The structure is simple, time-saving and convenient.

[0044] The main functions of this utility model are:

[0045] By optimizing the sintering machine trolley structure, changing the installation method of the heat insulation components at both ends of the trolley, and modifying the trolley frame structure, the width of the end heat insulation component base is reduced. This allows the heat insulation components to be placed on the base from above without removing the side panels. Two limiting holes are made on the sides of the heat insulation components and the end heat insulation base, and locking pins are inserted to fix the heat insulation components to the base. Thus, the original slot-type installation is eliminated, and a locking pin type is adopted, eliminating the need to remove the side panels when replacing the grate bars and heat insulation components.

[0046] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
