[0002] The coal tamping process refers to a special technical measure for preparing coking coal by using special coal tamping machinery to tamp the coal into briquettes before loading it into the coke oven, thereby increasing its bulk density before loading it into the oven. This technical measure can also expand the source of coking coal, add more high-volatile, medium or weakly coking coal, and ensure the quality of coke.

[0003] The tamping machine hammer stop device is a device that returns the tamping machine hammer to the original stop hammer position after the coke oven tamping machine completes the tamping of coal cakes. It is one of the core equipment to ensure safe production. The traditional tamping machine hammer stop device is generally composed of a group of three. When an accident occurs or when a tamping hammer fails, even if the other tamping hammers do not fail, the tamping machine cannot continue to work and needs to be shut down for repairs.

[0017] By adopting the above technical solution, when there is no need to stop the hammer normally, the piston rod of the hydraulic cylinder is started to extend, driving the first connecting rod to move in the direction close to the second connecting rod, and driving the first connecting block to move in the direction close to the second connecting block. At this time, the hypotenuse of the first connecting block abuts against the hypotenuse of the second connecting block, thereby driving the second connecting block to move in the direction close to the gasket, thereby driving the second connecting rod to move in the direction close to the card interface, thereby driving the gasket to move in the direction close to the card interface until the gasket moves into the card interface and blocks the card interface. At this time, the hammer rod can be raised and lowered normally; by sliding the gasket on the frame, the moving direction of the gasket can be limited, thereby limiting the moving directions of the second connecting rod and the second connecting block, so that the gasket can only move in the same direction close to or away from the card interface; by setting the first connecting rod, and connecting one end of the first connecting rod to the hydraulic cylinder The piston rod is fixedly connected, so that when the piston rod of the hydraulic cylinder moves, it can drive the first connecting rod to move; by setting the first connecting block and fixing the first connecting block to the first connecting rod, when the piston rod of the hydraulic cylinder drives the first connecting rod to move, it can drive the first connecting block to move together; by setting the second connecting rod and fixing the second connecting rod to the gasket, when the second connecting rod moves, it can drive the gasket to move together; by setting the second connecting block and fixing the second connecting block to the second connecting rod, when the second connecting block moves, it can drive the second connecting rod to move together; by setting the cross-sections of the first connecting block and the second connecting block into right-angled triangles and abutting the hypotenuses of the two, when the hydraulic cylinder drives the first connecting block to move in a direction close to the second connecting block, it can drive the second connecting block to move in a direction close to the card interface.

[0019] By adopting the above technical solution, when it is necessary to stop the hammer, the piston rod of the hydraulic cylinder moves in a direction away from the guide column, which can drive the first connecting rod and the second connecting block to move in a direction away from the gasket. At this time, the second connecting block moves in a direction close to the fixed block under the action of the contraction force of the second spring, thereby driving the second connecting rod to move in a direction close to the fixed block, thereby driving the gasket away from the card interface, so that the card interface opens. When the hammer rod is lifted or lowered, when the card block is aligned with the card interface, the card block can be clamped in the card interface under the action of the tension of the first spring, so that the hammer rod cannot be lifted or lowered, thereby achieving the purpose of stopping the hammer.

[0020] Optionally, a side of the block away from the telescopic rod is arc-shaped.

[0021] By adopting the above technical solution, when there is no need to stop the hammer, the blocking block abuts against the inner wall of the guide column under the tension of the first spring.

[0025] By adopting the above technical scheme, when the hammer does not need to be stopped and the machine works normally, the piston rod of the hydraulic cylinder is extended, driving the gasket to block the card interface, and at the same time driving the end of the rotating rod away from the safety lever to rotate toward the direction close to the guide column, thereby driving the end of the rotating rod close to the safety lever to move in the direction away from the hammer head, so that the safety lever and the hammer head are staggered in the vertical direction, so that the hammer head can be lifted and lowered normally; when the hammer needs to be stopped, the piston rod of the hydraulic cylinder is shortened, driving the gasket to move to open the card interface, and at the same time driving the end of the rotating rod away from the safety lever to move in the direction away from the guide column, thereby driving the end of the rotating rod close to the safety lever to move in the direction close to the hammer head, so that the safety lever moves to under the hammer head, thereby preventing the hammer head from falling and improving its safety; and a hydraulic cylinder can simultaneously drive the card block for clamping and the safety lever for protection, thereby improving work efficiency.

Through the arrangement of the hydraulic cylinder, the first connecting assembly and the gasket, when the hammer does not need to be stopped, the hydraulic cylinder can be used to drive the gasket to block the card interface, so that even if the card block is aligned with the card interface, it cannot be stuck at the card interface, thereby allowing the hammer rod to be lifted and lowered normally; 3. Through the arrangement of the first connecting rod, the second connecting rod, the first connecting block and the second connecting block, when there is no need to stop the hammer normally, the piston rod of the hydraulic cylinder is started to extend, driving the first connecting rod to move in the direction close to the second connecting rod, and driving the first connecting block to move in the direction close to the second connecting block. At this time, the beveled edge of the first connecting block abuts against the beveled edge of the second connecting block, thereby driving the second connecting block to move in the direction close to the gasket, thereby driving the second connecting rod to move in the direction close to the card interface, thereby driving the gasket to move in the direction close to the card interface, until the gasket moves into the card interface and blocks the card interface, and at this time the hammer rod can be raised and lowered normally.

[0038] When the hammer does not need to be stopped and the machine works normally, the piston rod of the hydraulic cylinder 7 is extended, driving the gasket 13 to block the card interface 21, and at the same time driving the end of the rotating rod 93 away from the safety gear rod 5 to rotate in the direction close to the guide column 2, thereby driving the end of the rotating rod 93 close to the safety gear rod 5 to move in the direction away from the hammer head 4, so that the safety gear rod 5 is staggered with the hammer head 4 in the vertical direction, so that the hammer head 4 can be lifted and lowered normally; when the hammer needs to be stopped, the piston rod of the hydraulic cylinder 7 is shortened, driving the gasket 13 to move to open the card interface 21, and at the same time driving the end of the rotating rod 93 away from the safety gear rod 5 to move in the direction away from the guide column 2, thereby driving the end of the rotating rod 93 close to the safety gear rod 5 to move in the direction close to the hammer head 4, so that the safety gear rod 5 moves below the hammer head 4, thereby preventing the hammer head 4 from falling.

[0039] The implementation principle of a safety single-stop hammer device for a tamping machine in the embodiment of the present application is as follows: When the hammer does not need to be stopped during normal operation, the piston rod of the hydraulic cylinder 7 is started to extend, driving the first connecting rod 81 to move in the direction close to the second connecting rod 83, and driving the first connecting block 82 to move in the direction close to the second connecting block 84.

[0040] When it is necessary to stop the hammer, the piston rod of the hydraulic cylinder 7 moves in a direction away from the guide column 2, which can drive the first connecting rod 81 and the second connecting block 84 to move in a direction away from the gasket 13. At this time, the second connecting block 84 moves in a direction close to the fixed block 14 under the action of the contraction force of the second spring 15, thereby driving the second connecting rod 83 to move in a direction close to the fixed block 14, thereby driving the gasket 13 away from the card interface 21, so that the card interface 21 is opened. When the hammer rod 3 is lifted or lowered, when the card block 61 is aligned with the card interface 21, the card block 61 can be clamped in the card interface 21 under the tension of the first spring 62, so that the hammer rod 3 cannot be lifted or lowered, thereby achieving the purpose of stopping the hammer; while the piston rod of the hydraulic cylinder 7 is shortened, it drives the end of the rotating rod 93 away from the safety gear rod 5 to move in a direction away from the guide column 2, thereby driving the end of the rotating rod 93 close to the safety gear rod 5 to move in a direction close to the hammer head 4, so that the safety gear rod 5 moves below the hammer head 4, thereby preventing the hammer head 4 from falling.
