Description

Technical Field

[0001] The utility model relates to the technical field of tamping hammer maintenance, in particular to a maintenance machine for a coke oven tamping hammer. Background Art

[0002] Ramming coke oven refers to a side-loading coke oven that uses the ramming method to load coal for coking. Ramming coke generally refers to coke produced in a special ramming coke oven using ramming coking technology. Ramming coking technology is a coking technology that can add more high-volatile coal and weakly caking coal according to the different uses of coke. After the prepared coal is compacted in the coal box of the coal-loading coke car with a tamping machine, it is pushed from the side of the coke oven into the carbonization chamber for high-temperature dry distillation. The ramming coking process is to use tamping equipment outside the coke oven to press the coking coal into the carbonization chamber. The size of the coal is rammed into coal cakes slightly smaller than the carbonization chamber, and the coal cakes are pushed into the carbonization chamber from the side of the carbonization chamber for high-temperature carbonization. The mature coke is pushed out of the carbonization chamber by the tamping and pushing machine, and sent to the coke quenching tower by the coke blocking car and the coke quenching car. It is quenched with water and then placed on the coke cooling platform. It is transported by belt and separated into commercial coke of different particle sizes through coke screening. The tamping hammer of the tamping coke oven will wear during use. In order to avoid affecting the normal production and use after the tamping hammer of the tamping coke oven is worn, a tamping hammer maintenance machine is needed.

[0003] The surface of the existing tamping hammer will be deformed during use. After deformation, it needs to be flattened using a clamping hydraulic cylinder and a support seat in a tamping hammer maintenance machine. However, the current maintenance machine has a complicated fixing method and requires a variety of tools to operate, which is inefficient and has no supporting effect. The equipment bears a heavy load during maintenance and is prone to malfunctions.

[0004] Therefore, improvements are made to address the above problems. Utility Model Content
