Description

Technical Field

[0001] The utility model relates to a coal unloading grate for a car tipper and belongs to the technical field of car tipper equipment. Background Art

[0002] The coal unloading grate of the dumper is welded in a "field" shape by staggered steel plates of the fixed frame horizontally and vertically. The size of the coal unloading grate hole is fixed during the unloading process of the dumper. The coal unloading grate can not only withstand the impact and crushing of coal powder, but also ensure the passage of coal powder of appropriate size. However, for some special types of coal, it is very easy to adhere to the grate hole under the action of moisture to form coal accumulation. Because the size of the coal unloading grate hole is fixed, it is also difficult to discharge the accumulated coal during the operation of the dumper. Because of the excessive coal accumulation, the dumper operation cannot be rotated in place, and the coal accumulation in the coal unloading grate needs to be manually cleaned before normal dumping operation can be carried out.

[0003] Coking coal in a coking plant generally requires several different types of coal to be used in combination to reduce production costs. During the transportation of these coal types, some are prone to compaction due to their different characteristics, which is particularly prominent in winter weather. In the same coal unloading grate, the grate gap cannot be adjusted, which reduces the efficiency of coal unloading by the dumper. Therefore, a coal unloading grate for a dumper is proposed to improve the coal unloading efficiency of different types of coal. Utility Model Content

[0004] The utility model aims to provide a coal unloading grate for a car dumper, which can avoid coal accumulation in the grate holes, improve the coal unloading efficiency for different types of coal, and solve the problems existing in the background technology.

[0005] The technical solution of the utility model is:

[0006] A coal unloading grate for a car dumper comprises a fixing frame, a steel wire rope and a stainless steel casing. The fixing frame is a grid structure formed by welding a plurality of steel plates together in a staggered manner horizontally and vertically to form a plurality of rows and columns of grate holes. A steel wire rope is arranged in the middle of each row or column of grate holes, and a stainless steel casing is put on each steel wire rope. The stainless steel casing divides the grate holes in each row or column into two symmetrical parts.

[0007] One end of the steel wire rope is fixed on the fixing frame through a tripod, and the other end of the steel wire rope is wound on a reel.

[0008] The tripod is welded to one side of the fixing frame, a lifting ring is arranged on the tripod, a steel wire rope is tied to the lifting ring, and a reel is rotatably connected to the other side of the fixing frame.

[0009] The tripod and the reel correspond one to one.

[0010] The tripod is an equilateral triangle.

[0011] The beneficial effects of the utility model are: it can avoid the formation of coal accumulation in the grate holes, which causes the car tipper to not rotate properly and affects the normal operation of the car tipper, and improves the coal unloading efficiency of different types of coal.

[0017] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0018] See attached Figure 1-4 A coal unloading grate for a dumper comprises a fixing frame 1, a steel wire rope 2 and a stainless steel casing 3. The fixing frame 1 is a grid structure formed by welding a plurality of steel plates together in a staggered manner horizontally and vertically to form a plurality of rows and columns of grate holes. A steel wire rope 2 is arranged in the middle of each row or column of grate holes, and a stainless steel casing 3 is put on each steel wire rope 2. The stainless steel casing 3 divides the grate holes in each row or column into two symmetrical parts.

[0019] In this embodiment, refer to the attached Figure 1-4 The fixed frame 1 is a commonly used component of a coal unloader. It is a grid structure composed of several steel plates welded together horizontally and vertically to form several rows and columns of grate holes. In this embodiment, the size of the grate holes of the fixed frame 1 is 300mmX300mm.

[0020] A steel wire rope 2 is arranged in the middle of each row of grate holes, and a stainless steel sleeve 3 is put on each steel wire rope 2. The stainless steel sleeve 3 divides the grate holes in each row into two symmetrical parts, that is, the size of the grate holes becomes 300mmX150mm.

[0021] During installation, first weld the tripod 5 with the lifting ring 8 to one side of the fixed frame 1, and rotatably connect the drum 4 to the other side of the fixed frame 1, so that the tripod 5 and the drum 4 correspond one to one, and tie one end of the wire rope 2 to the lifting ring 8, and the other end is wound around the drum 4; the drum 4 adopts a common gear-type hand-cranked structure, which is locked when in the meshing state, and is driven by the hand-cranked gear when not in the meshing state, driving the drum to adjust the length of the wire rope.
