Adjustable multifunctional excitation device of vibratory roller

Abstract

The invention provides an adjustable multifunctional excitation device of a vibratory roller, which comprises a controller used for controlling the entire vibratory roller, wherein the controller is connected with a valve via conductors; the valve is communicated with a vibration exciter via a rotary connector and a hydraulic lock; the vibration exciter is characterized in that a main driving gear engaged with a primary forward gear and a secondary forward gear is arranged on the output shaft of a hydraulic motor; a primary driving shaft is arranged on the primary forward gear; a primary clutch and at least one primary eccentric block are arranged on the primary driving shaft; a gear shaft of a primary reverse gear is connected with a rotary oil cylinder; the oil port ends A and B of the rotary oil cylinder are communicated with the two corresponding oil port ends F and G of the valve via the rotary connector; the output shaft of the rotary oil cylinder is connected with the primary driving shaft; a secondary driving shaft is arranged on the secondary forward gear; a secondary clutch and at least one secondary eccentric block identical with the primary eccentric block are arrangedon the secondary driving shaft; and a secondary reverse gear engaged with the primary reverse gear is arranged at the other end of the secondary driving shaft.

Description

technical field

[0001] The invention belongs to the technical field of paving and repairing machines, tools or auxiliary equipment for pavement of roads or other similar structures, and in particular relates to vibration compaction machinery in construction machinery. Background technique

[0002] According to the compaction theory, the vibration modes of the vibration wheel excitation device include ordinary vibration compaction, vibration compaction, vertical vibration compaction and impact vibration compaction.

[0003] Ordinary vibratory compaction relies on the combined action of the mass of the machine itself and the exciting force generated by the exciting device to reduce the internal friction between the particles of the pressed material, wedge the soil particles tightly, and achieve the purpose of compacting the soil. Vibratory compaction has the characteristics of concentrated static load and dynamic load combined compaction, and has the characteristics of strong ...
