It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] The utility model is further described below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 5 As shown, a large sintering trolley comprises a trolley wheel 1, a mounting plate 2, a grate bar 4, a guardrail 3 and a trolley beam 6, wherein the trolley beam 6 is arranged horizontally and transversely, and the trolley beam 6 is provided with a plurality of trolley wheels 1, which are evenly and equidistantly arranged. The trolley wheel 1 is fixed at both ends of the trolley beam 6, and the trolley wheel 1 is placed on a track, and the mounting plate 2 is fixed at both ends of the trolley beam 6, and the guardrail 3 is fixed at the upper end of the mounting plate 2. A plurality of heat insulating members 5 are provided on the trolley beam 6, and the heat insulating members 5 include a middle heat insulating pad 51 and an end heat insulating pad 52, and a plurality of the middle heat insulating pads 51 are provided, and two of the end heat insulating pads 52 are provided, which are respectively arranged at both ends of the trolley beam 6;

[0028] Notches 63 are respectively provided at the left and right ends of the trolley beam 6, and a slide groove 64 is provided between the notches 63 of the trolley beam 6. A limiting portion is provided at the lower end of the middle thermal insulation pad 51, and the limiting portion is engaged in the slide groove 64. When the middle thermal insulation pad 51 is installed on the trolley beam 6, the limiting portion on the middle thermal insulation pad 51 is engaged in the slide groove 64, ensuring that the middle thermal insulation pad 51 is stably installed on the trolley beam 6 and will not shake or fall off.

[0029] The two ends of the trolley beam 6 are respectively provided with clamping blocks 8, which can fill the gap between the end insulation pad 52 and the guardrail 3, making the connection between them more secure and preventing the end insulation pad 52 from falling off.

[0030] There are a plurality of grate bars 4 placed on the heat insulating member 5 . The grate bars 4 are placed perpendicular to the trolley beam 6 , and the legs of the grate bars 4 are clamped at the lower end of the heat insulating member 5 .

[0031] The lower ends of the middle insulation pad 51 and the end insulation pad 52 are provided with insulation cotton 9, and the insulation cotton 9 is bonded and fixed thereto. The insulation cotton 9 is made of asbestos, and bonding and fixing facilitates installation and disassembly and maintenance. The insulation cotton 9 can not only play a buffering role but also has a further insulation effect.

[0032] A guide column 522 is provided at the bottom of the end thermal insulation pad 52, and a guide hole 62 is provided on the upper surface of the notch 63. When the end thermal insulation pad 52 is placed at the notch 63, the guide column 522 is placed in the guide hole 62. The cooperation between the guide column 522 and the guide hole 62 can allow the end thermal insulation pad 52 to be quickly positioned, thereby improving installation efficiency.

[0033] A lifting ear 521 is provided at the upper end of the end heat insulation pad 52 . There are two lifting ears 521 symmetrically welded on the upper surface of the end heat insulation pad 52 . The lifting ears 521 are convenient for subsequent lifting operations and are easy to take and put.

[0034] A plurality of support plates 7 are provided between the trolley beams 6, the support plates 7 are fixedly connected to the trolley beams 6 by welding, and the support plates 7 are evenly and equidistantly arranged;

[0035] A plurality of vertical reinforcing ribs 61 are disposed on the front side of the trolley beam 6 . The vertical reinforcing ribs 61 are connected to the trolley beam 6 as a whole, and the reinforcing ribs enhance the strength of the trolley beam 6 .

[0036] The use principle of the utility model is as follows: when in use, if the heat insulating member 5 is damaged, the clamping blocks 8 at both ends can be taken out first. After the clamping blocks 8 are taken out, the end heat insulating pads 52 will be loosened, so that the end heat insulating pads 52 can be taken out by using the lifting ears 521 at the upper ends, and then the middle heat insulating pad 51 can be pushed to the left and right ends along the slide groove 64. When the notch 63 is reached, since the length of the notch 63 is slightly larger than the length of the middle heat insulating pad 51, the middle heat insulating pad 51 can be directly taken out;

[0037] In this way, the disassembly operation of the guardrail 3 can be eliminated, and the end insulation pad 52 and the middle insulation pad 51 can be directly removed and installed and maintained, which reduces labor intensity, greatly saves time and improves work efficiency.
