Biaxial inertia excitation tamping pick

Abstract

The invention provides a biaxial inertia excitation tamping pick, and relates to railway maintenance equipment, in particular to the biaxial inertia excitation tamping pick with the advantages that directional vibration force is provided, and the vibration effect is good. The biaxial inertia excitation tamping pick uses a gasoline engine or a diesel engine as prime power. The biaxial inertia excitation tamping pick is characterized in that the tamping pick comprises a tamping handle, a tamping case, a vibration reduction tube, a transmission device and an excitation vibration component, wherein the vibration reduction tube is fixed on the top of the tamping case; the tamping handle is arranged on the vibration reduction tube; the excitation vibration component is arranged inside the tamping case, and is connected with the prime power through the transmission device. Through two parallel excitation vibration shafts and two groups of eccentric blocks in opposite arrangement on the excitation vibration shafts, the two groups of eccentric blocks enable vibration excitation forces at the left side and the right side of the tamping pick to mutually counteract and to be converted into vibration excitation force in a front and back direction; the tamping efficiency is improved; meanwhile, a flow guide plate is added; the flow guide plate is used for decomposing the front and back force into forward force and downward force, so that a pick head can automatically move forwards; front ballast is pushed and naturally flows to the bottom of a sleeper; the special requirements of railway construction are met.

Description

technical field [0001] The invention relates to railway maintenance equipment, in particular to a dual-axis inertial vibration tamping pick which provides directional vibration force and good vibration effect. Background technique [0002] The tamping pick is a hand-held, portable special tool suitable for tamping ballast on the railway track bed. Gasoline engine or diesel engine is used as the driving force, and the centrifugal clutch, eccentric shaft, and rubber shock absorber drive the pick body to generate high-frequency disturbance force, so that the ballast under the pillow is rearranged and compacted, so as to achieve the purpose of tamping the ballast on the ballast bed. After the roadbed ballast has been cleaned and screened, the ballast is tamped and distributed evenly with a tamping pick, and the gap under the sleeper is filled to meet the requirements of a dense and smooth roadbed. Most of the existing tamping picks belong to the single-axis circular vibration, ...

AI Technical Summary

Problems solved by technology

[0003] What the present invention aims to solve is the problem that the existing tamping pick has single-axis circular vibration, the vibration effect is poor, it needs to be compensated manually, and the efficiency is low. It provides a dual-axis inertial excitation vibration tamping pick that provides directional vibration force and good vibration effect.
