Abstract
The utility model discloses a sintering machine trolley grid pin, which comprises a grid pressing block and an assemble-shaped pin rod, wherein the grid pressing block and the assemble-shaped pin rod are integrated or welded into a body; because the assemble-shaped pin rod of the utility model comprises a cylindrical section and a round table section, one end of the round table section is easy to insert into the pin holes of the sintering machine trolley at assembling, and the installation and the disassembly are very convenient; moreover, the matching gap of the cylindrical surface of the cylindrical section and the grid pin holes on the sintering machine trolley is small, eliminating the phenomenon of air leak of the grid pin holes.
Description
Technical field
The utility model relates to a kind of sintering pallet grate bar pin that uses on the chassis of field of metallurgy sintering machine.
Background technology
The sintering pallet grate bar pin that uses in the prior art is made up of grate bar briquetting, cylindrical pin sub bar usually, is drilled with the pinhole that is used to wear spacing pin on the pin bar; In use sintering pallet grate bar pin is passed the grate bar pinhole on the chassis.For preventing that in use sintering pallet grate bar pin falls down, sintering pallet grate bar pin is plugged spacing pin at the pinhole of pin bar end after passing chassis grate bar pinhole.In process of production, the fast quick-detach and the installation of grate bar pin for convenience, the diameter of pinhole so just causes grate bar pinhole place to leak out than the big 2-3 millimeter of the pin shank diameter on the grate bar pin on the sintering pallet usually.
The utility model content
At above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of and can removes and installs fast, can eliminate the novel sintered machine trolley grate bar pin that leaks out in grate bar pinhole place again.
For achieving the above object, technical solution of the present utility model is:
A kind of sintering pallet grate bar pin comprises grate bar briquetting and combined shaped pin bar, and this grate bar briquetting and combined shaped pin bar are one-body molded or be welded as a whole.
Further, be drilled with the pinhole that is used to be provided with spacing pin on the described combined shaped pin bar.
Further, described combined shaped pin bar is made up of cylindrical section and round platform section.
Further, described combined shaped pin bar is made up of cylindrical section and conical section.
Further, the length of described round platform section or conical section should be equal to or greater than cylindrical section length 80%.
Further, the fit clearance of the face of cylinder of described cylindrical section and the grate bar pinhole on the sintering pallet is less than 0.1 millimeter.
After adopting said structure,, be easy to during installation a round table-like or cone shape end is inserted in the sintering pallet pinhole, make installation and removal very convenient because combined shaped pin bar of the present utility model comprises cylindrical section and round platform section or conical section two parts; And the fit clearance of the face of cylinder of cylindrical section and the grate bar pinhole on the sintering pallet is less, has eliminated the air leakage phenomena at grate bar pinhole place.
Description of drawings
Fig. 1 is the front view of the utility model sintering pallet grate bar pin;
Fig. 2 is the sorrowful view of the utility model sintering pallet grate bar pin;
Fig. 3 is the vertical view of the utility model sintering pallet grate bar pin.
The specific embodiment
As shown in Figure 1, 2, 3, the utility model sintering pallet grate bar pin comprises grate bar briquetting 1 and combined shaped pin bar 2, and this grate bar briquetting and combined shaped pin bar are one-body molded or be welded as a whole; This combined shaped pin bar 2 is made up of cylindrical section 5 and round platform section 6, and in use for eliminating the air leakage phenomena at grate bar pinhole place, the fit clearance of the face of cylinder of cylindrical section 5 and the grate bar pinhole on the sintering pallet is less than 0.1 millimeter.Also be drilled with pinhole 3 on the combined shaped pin bar 2, in use spacing pin 4 passed above-mentioned pinhole 3 to carry out spacing to grate bar pin; For ease of the installation and removal of grate bar pin, the length of the round platform section 6 of described combined shaped pin bar 2 should be equal to or greater than cylindrical section 5 length 80%.In addition, above-mentioned round platform section 6 also can be made as coniform.
Because combined shaped pin bar 2 ends of the utility model sintering pallet grate bar pin are the round platform sections, be easy to during installation an end of truncated conical shape is inserted in the chassis pinhole, impact with hammer again, grate bar pin can be in place, again spacing pin is passed the pinhole on the combined shaped pin bar, promptly finished the Fast Installation of grate bar pin.During dismounting, the spacing pin on the combined shaped pin bar is taken out, beat combined shaped pin bar end with hammer, grate bar pin is promptly dismountable.
