Description

Technical Field

[0001] The utility model relates to the technical field of tamping machines, in particular to a hammer working device for tamping machines. Background Art

[0002] The tamping machine is a specialized piece of equipment used in the tamping coking industry and is a core component of coke oven machinery. A complete tamping machine typically consists of 4-6 tamping trolleys. Each tamping trolley is equipped with a hammer lifting device, primarily comprised of a speed reducer, a hammer lifting cam assembly, a power shaft, a bearing seat, and other components. It is the power component that drives the tamping hammer and is one of the core components of the tamping trolley. It moves by using power from the drive motor to drive the hammer lifting device. The large bearings in the cam assembly of the hammer lifting device come into contact with the friction plates of the tamping hammer, generating frictional extrusion to generate the hammer lifting force.

[0003] In the utility model with publication number CN217149077U, entitled A Hammer Working Device for a Tamping Machine, a hammer working device for a tamping machine is disclosed. By making the structures of the first connecting member and the second connecting member identical and by arranging a spline shaft and a matching spline groove, the service life of the equipment can be greatly improved. In actual use, the spline shaft and the matching spline groove increase the firmness to a certain extent compared with ordinary matching. However, damage will still be caused under high intensity, and the socket and cam disc of the current active cam are connected by welding. Under long-term high-intensity use, the welding quality is difficult to guarantee. Utility Model Content
