Description

Novel alloy tamping pickaxe

Technical Field

The utility model belongs to the technical field of the tamping pick, concretely relates to novel alloy tamping pick.

Background

The tamping pickaxe is a small railway maintenance machine used in railway construction and maintenance operation, is mainly applied to railway ballast tamping operation, and can be divided into an electric tamping pickaxe and an internal combustion tamping pickaxe according to a power source; the portable tamping pickaxe and the split tamping pickaxe can be divided according to the structure; the vibrating type tamping pickaxe can be divided into a rotating shaft horizontal tamping pickaxe and a rotating shaft vertical tamping pickaxe according to the vibrating mode of the vibrating type tamping pickaxe.

The tamping pick generates vibration force to ballast by the vibration of a pick tip, and the vibration force overcomes the friction force between the ballast; the ballast is in a flowing state, so that the ballast moves to a more stable position, the ballast under the sleeper is more compact, the clamping action in the tamping operation enables the ballast at the interval end of the sleeper to be extruded to the sleeper bottom, the ballast at the sleeper bottom is more compact, the ballast bed is more stable, in the using process of the tamping pick, as the mutual vibration friction is formed between the tamping pick and the ballast, the vibrating mechanism drives the peripheral ballast to move to a loose position, so that the compactness under the sleeper is improved, in the practical use process, because the tamping pick and the ballast are in direct contact friction, the outer wall of the tamping pick is abraded, the tamping pick needs to be replaced after being used for a period of time, otherwise, the problem of poor vibrating effect is caused, therefore, in the preparation of the tamping pick, alloy materials are added in the tamping pick, the abrasion resistance hardness of the tamping pick is increased, the hardness of the tamping pick is generally about ten times of the hardness of the common tamping pick, and the tamping pick has better abrasion resistance, but at the in-process of long-time using, still need carry out whole change to it after life reaches, the wearing and tearing face mainly is the pick point outer wall, and the spliced pole of pick point upper end fixed and top organism bolted connection, the weak point that exists has: the existing tamping pickaxe generally adopts integral replacement for the replacement of the tamping pickaxe in the long-time use process, the connecting column positioned above the tamping pickaxe is replaced together, certain resource waste is caused, the connecting column is worn and torn after the pickaxe tip is deeply inserted into ballast, and the connecting column also has certain service life, but the service life of the connecting column is far longer than that of the pickaxe tip, the pickaxe tip and the connecting column in the tamping pickaxe are integrated, and the problem of resource waste can be caused during the replacement.
