A liquid stepless amplitude modulation exciter for a vibratory road roller

Abstract

The invention discloses a vibratory roller liquid stepless amplitude modulation vibration exciter; an output terminal of a hydraulic motor mounted on a frame is connected with a vibration shaft; a light pipe and a heavy pipe are mounted on the vibration shaft; the light pipe and the heavy pipe are symmetrically arranged with an included angle of 180 degrees, are communicated through a connecting pipe, and are sealed with liquid filled inside; the right end of the vibration shaft is mounted with a swivel joint; the upper end of the swivel joint is connected with a light pipe gas inlet through a light pipe gas inlet pipe; the upper gas inlet pipe is connected with a right path of a hydraulic lock; the lower end of the swivel joint is connected with a heavy pipe gas inlet through a heavy pipe gas inlet pipe; and the lower gas inlet pipe is connected with a left path of the hydraulic lock; the hydraulic lock is orderly connected with a reversing valve and a gas source; through controlling the gas pressure and flow rate, the device can control the amount of liquid entering the light pipe and the heavy pipe, realize stepless adjustment of the amplitude of a vibrating drum, and thus realize long-distance intelligent control of a vibratory roller.

Description

technical field [0001] The invention relates to an indispensable compaction device in road construction, in particular to a vibratory road roller, in particular to a liquid stepless amplitude modulation exciter for a vibratory road roller, which belongs to the field of road construction machinery. Background technique [0002] The operating device of the vibratory roller is a vibrating wheel, whose function is to force the vibrating wheel to vibrate through the high-speed rotation of its internal eccentric components, and realize the compaction operation of various road construction projects. Vibratory roller vibratory devices at home and abroad are divided into fixed type and step-adjustable type. The fixed type is a single-amplitude vibration shaft, which has the advantages of simple structure, easy manufacture, and good reliability. And multi-width vibrating shafts, most of the existing step-adjustable vibratory rollers are double-width vibrating shafts, and a few are mu...

AI Technical Summary

Problems solved by technology

The above types of mechanisms are inseparable from the mechanical eccentric block, which has the following two defects: (1) the structure is complex, it is inconvenient to disassemble and install, and the time for installation and maintenance is prolonged; (2) it is not conducive to remote control, Restricting the level of automation and intelligence of vibratory rollers
