Abstract
The utility model relates to a multi-frequency synthetic vibration exciter for vibrating compaction. Two or more than two eccentric shafts which are connected with each other through one transmission mechanism or more than one transmission mechanism are arranged in a vibration exciter box body, a shaft rod of one of the eccentric shafts is connected with an external dynamic force output shaft through a transmission mechanism in a transmission way; at least two eccentric shafts of all the eccentric shafts are connected with each other through a variable-speed transmission mechanism, and the eccentric shafts rotating at variable speeds are provided with eccentric blocks of which the quantity and the size are unequal. When the utility model is in operation, a comparatively wide vibration frequency domain is generated by the vibration exciter, and a large quantity of exciting force with different frequency at any time acts on pressed materials; thus, the pressed materials can reach the effect of resonant compaction.
Description
Affiliated technical field
The utility model belongs to building and road building machinery technical field, relates to a kind of vibratory compaction vibrator.
Background technology
Compacting is main means of strengthening engineering structure basis, dykes and dams and paving layer etc.In recent years, be compacted the continuous variation of the diversity and the physical-mechanical properties of material in compacting process of material for adaptation, improve compacting efficient and degree of compaction, people have adopted multiple method of work, as adopt vibratory compaction technology of frequency conversion luffing vibrator etc., so that at different compacting occasion conversion vibration frequency and amplitude.But owing to be compacted the difference of the diversity of material and granular size, composition etc., its intrinsic frequency is one to have the frequency domain of relative broad range, even conversion vibration frequency and amplitude in compacting process, vibrator also only has a kind of vibration frequency and corresponding amplitude thereof constantly in arbitrary work, and this single-frequency mode of vibration is difficult to make and is compacted the Expected Results that material reaches the resonance compacting.
The utility model content
The purpose of this utility model is the problem that prior art exists is solved, and then a kind of simple in structure, high efficiency is provided, can adapts to the vibratory compaction multi-frequency synthetic vibration exciter of multiple constructional materials compacting operation.
Be used to realize that the technical solution of foregoing invention purpose is such: in the vibrator casing, be provided with the eccentric shaft that two or more connect by transmission mechanism (as gear or synchronous cog belt etc.), the axostylus axostyle of one of them eccentric shaft is in transmission connection by transmission mechanism and outer power output shaft, have at least between two eccentric shafts to connect by the variable speed transmission mechanism in each eccentric shaft, the eccentric shaft that each variable speed rotates is equipped with the mutual unequal eccentric block of quality size.
The double-frequency composed vibrating pattern that the utility model adopts is meant the vibration mode that arbitrary moment all is composited by two or more simple harmonic oscillations, vibrator general performance in this pattern is a multifrequency resultant vibration of arbitrary moment, and it is different from arbitrary moment of in the past continuing to use this area only the FMAM technology of a simple harmonic oscillation.In the practical application, this vibrator can be installed on the frame of compacting machine, also can be set directly in the compacting machine roller.During work, vibrator can require to produce the vibration frequency domain of a broad according to difference, can there be the exciting force of a plurality of different frequencies, amplitude to act on so at any one time, adapts, reach the effect of resonance compacting with several main frequencies of being pressed material by the pressure material.Compared with prior art, the utlity model has simple in structure, high efficiency, consolidation effect is good, energy consumption is low, the reliability advantages of higher, can adapt to the compacting operation of multiple material.
