Vibration exciter, stabilizing device, stabilizing equipment and track maintenance vehicle

Abstract

The embodiment of the invention provides a vibration exciter, a stabilizing device, stabilizing equipment and a track maintenance vehicle, and relates to the technical field of equipment for track maintenance. The vibration exciter provided by the embodiment of the invention comprises a first vibration excitation shaft, a second vibration excitation shaft and a third vibration excitation shaft which are in transmission connection and are arranged in parallel. The first vibration excitation shaft is provided with a first eccentric block, the second vibration excitation shaft is provided with a second eccentric block, the third vibration excitation shaft is provided with a third eccentric block, when the vibration exciter is used, the whole vibration exciter only generates horizontal vibration excitation force through the first eccentric block, the second eccentric block and the third eccentric block, the horizontal vibration excitation force acts on a steel rail, and the stability of the rail is improved. The plane formed by the axes of two of the first vibration excitation shaft, the second vibration excitation shaft and the third vibration excitation shaft is obliquely arranged relative to the vertical plane, and compared with the height of an existing vertically-distributed three-shaft type vibration exciter, the height of the vibration exciter is effectively reduced, namely, the gravity center of the vibration exciter is reduced, and then the stability effect and the stability during operation can be improved.

Description

technical field [0001] The invention relates to the technical field of track maintenance equipment, in particular to a vibrator, a stabilizing device, stabilizing equipment and a track maintenance vehicle. Background technique [0002] After a period of use and operation of the gravel ballast bed, there will be ballast bed defects such as ballast bed deformation, ballast bed dirt, ballast bed hardening, etc., which will make the ballast bed lose its elasticity and affect the stability of driving. Therefore, cleaning and tamping operations are required. After cleaning and tamping operations on the railway line, the ballast bed is not dense enough, the lateral resistance and stability are poor, the train is forced to run at a limited speed, and the railway transport capacity is inevitably lost. The lateral resistance and the overall stability of the ballast bed, thereby avoiding slow trains and prolonging the overhaul time. [0003] The track stabilizing vehicle is designed t...
