Description

Technical Field

[0001] The utility model belongs to the technical field of coke pushing machine equipment, and in particular relates to a sliding shoe with a vibration reduction function used in a coke pushing device. Background Art

[0002] As a core raw material in industrial production, coke is widely used, especially in metallurgy, power and other industrial sectors. However, in the coke production process, the key equipment, the coke pusher, is often troubled by vibration. This vibration not only affects the working performance and life of the equipment, but also may cause production accidents and force the production process to be interrupted.

[0003] Domestic scholars have conducted in-depth research on this and pointed out that the main reasons for the vibration of the coke pusher during the coke pushing process include: the meshing quality of the driving gear and the rack, the horizontality of the lower support roller of the coke pusher, the horizontality of the coke pusher's running track, and the height of the slide. Although there is a plan to adjust the slide height by adjusting the gasket, the actual effect is not ideal.

[0004] In addition, the unevenness of the bottom of the carbonization chamber and the wear of the bottom of the push rod sliding shoe are also important causes of vibration. Although some improvement schemes, such as sliding shoes designed with hinge structures, are designed to balance pressure and reduce wear, vibration still exists in actual applications.

[0005] The prior art, such as the coke pushing device with a hexagonal eccentric sleeve, attempts to avoid the vibration of the coke pushing rod, but there is still a large collision and vibration when the sliding shoe contacts the bottom surface of the coke oven.

[0006] In summary, despite the existence of a variety of solutions, the vibration problem of the coke pusher has not been fundamentally solved. Therefore, it is urgent to conduct in-depth research and explore new technical solutions to effectively solve the vibration problem of the coke pusher and ensure the continuity of coke production and the safety of equipment, which has great practical significance for the smooth progress of industrial production.
