Problems solved by technology

Although there is a tamping effect, the strength of the ballast is weakened due to the impact, and the ballast slag produced by the impact affects the elasticity of the ballast bed
Therefore, it is not completely suitable for ballast tamping operations.

Embodiment Construction

[0027] The structure of the internal combustion centrifugal type tamping pick is described in detail below in conjunction with the accompanying drawings:

[0028] Such as figure 1 , figure 2 , image 3 and Figure 4 Shown: this tamping pick has a frame assembly 2 and an internal combustion engine 1 and a centrifugal vibrating device 5 installed on the frame assembly 2 , and a tamping plate 6 installed on the centrifugal vibrating device 5 . The power of the internal combustion engine 1 is connected to the centrifugal vibrating device 5 through the flexible shaft 4 . The upper end of the tamping plate 6 is fixed with the shell 8 of the centrifugal vibrating device 5, which has a bending angle downward.

[0029] see figure 2 , wherein the centrifugal vibration device 5 is composed of a driving gear 9 , a driven gear 12 , an eccentric block 11 , a housing 8 and an end cover 7 . The driving gear 9 is connected with the power output flexible shaft 4 of the internal combusti...

Abstract

The invention provides a portable centrifugal internal combustion tamping pick, comprising a rack assembly, an internal combustion engine, a centrifugal vibrating device and a tamping plate, wherein the centrifugal vibrating device comprises driving gears, driven gears, eccentric blocks and a shell; the driving gears are connected with a flexible axle; the driven gears and the driving gears are meshed, arranged horizontally and installed in the space formed by the shell and an end cover; the eccentric blocks with the same overall dimension and quality are symmetrically installed on the driving gears and the driven gears and always keep symmetric in the movement process of the two kinds of gears; and the upper end of the tamping plate is fixed with the shell of the centrifugal vibrating device. The hypocenter of the tamping pick is the centrifugal vibrating force generated by the eccentric blocks, horizontally vibrates the ballasts in multiple directions and can generate enough vibrating force to meet the tamping requirement of the ballasts.

Description

technical field [0001] The invention belongs to the tamping technology of railway bed ballast, and in particular relates to a tamping machine for railway maintenance. Background technique [0002] At present, small-scale ballast tamping operations on railway track beds are all completed by small tamping machines. Existing ballast tamping and drumming implements in use are of a great variety, but there is no one that is really suitable for ballast tamping operations. [0003] The currently used tamping rod type tamping machine, because the vibration source is installed in the tamping rod, the size cannot be enlarged because the tamping rod needs to be inserted into the ballast, and the vibration force generated is small due to the small size of the vibrating mechanism. The tinkering effect is poor, and the purpose of tinkering cannot be achieved. [0004] Because there is no suitable tamping tool, the impact breaker that was originally used to break the road surface is also...
