Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined to clearly and completely describe the technical solutions in the embodiments of the present invention, and obviously, the described embodiments are only a part of the embodiments of the present invention, not all embodiments. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. In the description of the present invention, the terms "first", "second", etc. are used only for distinguishing the description, and are not to be construed as merely or implying relative importance.

In the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 9, an electromagnetic tamping machine with a novel tamping hammer structure comprises a frame shell 1, a linear motor 2, a movable hinge 3, a hammer rod 4, a double-shaft positioning bolt 5, a guide wheel set 6, a tamping hammer reinforcing sleeve 7, a tamping hammer 8 and a hammer blocking safety lock 9.
