The insulation sleeve is fixed between the trolley guardrails, the trolley grate is installed on the insulation sleeve, and the briquetting pin is pressed on the grate. During the unloading process of the sintering machine, the high-temperature sintered ore is unloaded at an angle, which makes the trolley grate briquetting pin wear faster, causing the grate to fall off, affecting the service life of the briquetting pin. Utility Model Content

[0003] The utility model aims to provide a sintering machine trolley grate bar briquetting pin installation structure, which can reduce the wear of the briquetting pin by the high-temperature sintered ore during the sintering machine unloading process, increase the service life of the briquetting pin, avoid the grate bar from falling off, and solve the problems existing in the background technology.

[0004] The technical solution of the utility model is:

[0005] A sintering machine trolley grate briquetting pin installation structure comprises a trolley guardrail, a heat insulating sleeve, a trolley body, a trolley wheel and a trolley grate, wherein the heat insulating sleeve is fixed between the trolley guardrails, the trolley grate is fixed on the heat insulating sleeve, the trolley grate fixed on the heat insulating sleeve comprises special-shaped grate and ordinary grate, the ordinary grate is located in the middle of the trolley body, the special-shaped grate is located at both ends of the trolley body, and briquetting pins are provided on the special-shaped grate at both ends of the trolley body, the difference between the special-shaped grate and the ordinary grate is that a groove is provided in the middle of the special-shaped grate, one end of the briquetting pin is stuck in the groove in the middle of the special-shaped grate, and the other end of the briquetting pin is fixed on the trolley guardrail.

[0006] One end of the briquetting pin is in the shape of a larger rectangle, and the other end of the briquetting pin is in the shape of a smaller cylinder. The larger rectangular end of the briquetting pin is stuck in the groove of the special-shaped grate bar, and the smaller cylindrical end of the briquetting pin is fixed on the trolley railing.

[0007] The upper surface of the larger rectangular end of the pressing block pin is on the same plane as the upper surface of the special-shaped grate bar.

[0008] The cylindrical end of the pressing block pin with a smaller shape is fixed on the trolley guardrail through a fixing pin.

[0009] The trolley guardrail is provided with a through hole matching the cylindrical shape of the briquetting pin which is smaller in size.

[0010] The special-shaped grate bars at both ends of the trolley body are close to the trolley guardrail.

[0011] The utility model has the beneficial effects that during the sintering machine unloading process, since the briquetting pin is arranged in the groove of the special-shaped grate bar, the upper surface of the briquetting pin and the grate bar are in the same plane, thereby reducing the wear of the briquetting pin by the high-position sintered ore, increasing the service life of the briquetting pin, avoiding the grate bar from falling off, and reducing labor intensity.

[0019] In the figure: a trolley guardrail 1, special-shaped grate bars 2, ordinary grate bars 3, a block pin 4, a fixing pin 5, an insulation sleeve 6, a trolley body 7, trolley wheels 8, and a groove 9. DETAILED DESCRIPTION

[0020] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0021] See attached Figure 1-7 A sintering machine trolley grate briquetting pin installation structure comprises a trolley guardrail 1, a heat insulation sleeve 6, a trolley body 7, a trolley wheel 8 and a trolley grate, wherein the heat insulation sleeve 6 is fixed between the trolley guardrails 1, and the trolley grate is fixed on the heat insulation sleeve 6. The trolley grate fixed on the heat insulation sleeve 6 comprises a special-shaped grate 2 and a common grate 3, wherein the common grate 3 is located in the middle of the trolley body 7, and the special-shaped grate 2 is located at both ends of the trolley body 7. The special-shaped grate 2 at both ends of the trolley body 7 is provided with a briquetting pin 4. The difference between the special-shaped grate 2 and the common grate (3) is that a groove 9 is provided in the middle of the special-shaped grate 2, and one end of the briquetting pin 4 is stuck in the groove 9 in the middle of the special-shaped grate 2, and the other end of the briquetting pin 4 is fixed on the trolley guardrail 1.

[0022] In this embodiment, refer to the attached Figure 2 , 3The ordinary grate bar 3 is a grate bar commonly used in sintering machines, and the special-shaped grate bar 2 is a grate bar with a groove 9 added on the basis of the ordinary grate bar 3. The size of the groove 9 is made according to the size of the briquetting pin 4.

[0023] See attached Figure 4 , 5 6. One end of the briquetting pin 4 has a larger rectangular shape, and the other end has a smaller cylindrical shape.

[0024] See attached Figure 1 , 7 During installation, install the ordinary grate bar 3 in the middle of the sintering machine trolley body 7, and install 10 special-shaped grate bars 2 at both ends of the trolley body 7 respectively; clamp the larger rectangular end of the briquetting pin 4 in the groove 9 of the special-shaped grate bar 2, and make the upper surface of the rectangular end and the upper surface of the special-shaped grate bar 2 on the same plane; pass the smaller cylindrical end of the briquetting pin 4 through the trolley guardrail 1 and fix it with a fixing pin 5.

[0025] During the unloading process of the sintering machine, the high-temperature sintered ore is unloaded at an angle. This installation method reduces the wear of the briquetting pin by the high-temperature sintered ore because the upper plane of the briquetting pin 4 is in the same plane as the grate bars of the trolley, thereby increasing the service life of the briquetting pin, avoiding the falling off of the grate bars, and reducing labor intensity.
