Problems solved by technology

[0009] Aiming at the shortcomings of the traditional eccentric block type vibration mode and forced vibration type vibration mode of the existing tamping machine, the present invention proposes a new type of forced vibration type anti-phase vibration and tamping device based on the elastic connecting rod theory. Its purpose is to not only solve the problem that the traditional tamping machine cannot realize anti-phase vibration and asynchronous clamping, but also overcome the problem that the vibration amplitude of the traditional forced vibration excitation method cannot be adjusted, improve the tamping effect, and make the application of the tamping machine more flexible

Abstract

The invention discloses a shock exciting and tamping device and a parameter determination method of a hydraulic tamping machine, and belongs to the field of small-scale internal-combustion power hydraulic tamping machines for railway maintenance, and particularly relates to a forced-vibration type anti-phase shock exciting and tamping device based on an elastic linkage theory. In order to overcome the defects of a conventional eccentric block type shock exciting mode and the forced-vibration type shock exciting mode of a conventional tamping machine, a design theory of single-mass elastic-linkage type vibration is introduced, and a structure form and a parameter design method of a forced-vibration type anti-phrase shock exciting and tamping device based on the elastic linkage theory are provided; the invention aims to solve the problem that the conventional tamping machine cannot achieve anti-phase relative vibration and asynchronous clamping, and can solve the problem that a vibration amplitude of the conventional forced-vibration type shock exciting mode cannot be adjusted, so that tamping effects are improved and the tamping machine is more flexible to apply.

Description

technical field [0001] The invention belongs to the field of internal combustion power hydraulic tamping machines for small railway maintenance, and in particular relates to a forced vibration type anti-phase excitation and tamping device based on the elastic connecting rod theory. Background technique [0002] The tamping machine is mainly used for concrete pouring during construction and for tamping the ballast under the sleeper during railway maintenance. In the railway industry, it belongs to a special maintenance machine, which is mainly used for the tamping operation of the railway gravel track bed. [0003] At present, most of the railway subgrades in my country and even in the world adopt the structure of sleepers and crushed stone beds. It has a characteristic that it needs to be tamped every once in a while (depending on the frequency of trains) (crushed pieces that are about to be squeezed out) The tamping period of the high-speed trunk line is 3 to 6 days, and ta...
