Description
Technical Field
[0001] The utility model relates to the technical field of track maintenance, in particular to a track tamping machine with adjustable amplitude. Background Technique
[0002] In railway maintenance, tamping is an important task. It ensures the stability and safety of the track by compacting the ballast (crushed stones) under the track. Traditional tamping work is usually done manually, but now mechanical tamping devices are increasingly used to improve efficiency and quality. The tamping device in track maintenance is a mechanical device specifically used for railway track maintenance. Its main function is to compact the ballast under the track through vibration and pressure to ensure the stability and safety of the track.
[0003] The vibration of the tamping device is mainly achieved through a metal eccentric shaft. The metal eccentric shaft is installed on the vibration assembly. The eccentric vibration shaft is provided with two eccentric journal bearings arranged in a 180-degree phase. One end of the clamping oil cylinder is installed at the eccentric journal bearing, and the other end is hinged to the upper end of the pick arm. A tamping pick is installed at the lower end of the pick arm. The middle and upper part of the pick arm is hinged to the vibration assembly. In this way, a connecting rod type drive mechanism is formed. When the eccentric vibration main shaft rotates, the clamping oil cylinder will reciprocate under the drive of the eccentric shaft, thereby driving the end of the tamping pick to generate a swinging forced vibration. The tamping pick transmits the vibration force to the ballast, causing the ballast to vibrate and move in a more stable direction, increasing the compactness of the ballast bed.
[0004] During the use of the existing track tamping machine with adjustable amplitude, it is not convenient to adjust the use angle of the vibrating structure. The vibrating structure with a fixed angle may cause uneven compaction of the ballast in some areas, affecting the stability and smoothness of the track. Content of the Utility Model
