Description
Technical field
The present invention relates to a kind of spreader vibration device, especially relate to a kind of asphalt paver pair tamping equipment waiting stroke.
Background technology
Asphalt paver is requisite equipment in road machineization construction.Tamping equipment is one of groundwork device of paver, and it is close to before screed, plays tamping to material spreader, and its service behaviour has important impact to the planeness of paving concrete pavement and degree of compaction.Tamping equipment is generally divided into and singly vibrates and two two kinds of forms of vibrating, and wherein twoly vibrates because having higher precompressed solidity, so be widely adopted in paver.According to the direction of advance of paver, part of vibrating before two tamping equipment comprises and after to vibrate part, drive an eccentric shaft to rotate by power set, thus vibrate before driving part and after part of vibrating pump, realize making firm by ramming of bituminous mixture closely knit.
At present, two tamping equipment stroke that vibrates before being substantially all is that 0-3-6-9-12mm is adjustable, after the stroke that vibrates be the structure that 5mm is fixing.But, in practice of construction process, spreader vibration stroke infrequently regulating, the stroke that vibrates before mostly adopting is 6mm, after the stroke that vibrates be this mode of operation of 5mm.The stroke regulating mechanism that vibrates is made up of eccentric shaft and eccentric bushing, and eccentric bushing is placed on eccentric shaft, by the relative angle of eccentric adjustment cover with eccentric shaft, thus total offset that change eccentric shaft and eccentric bushing are formed, and then change the stroke that vibrates.Although before the stroke that vibrates adjustable, multiple parameter of vibrating can be provided for you to choose for user, bring adverse influence also to paver and performance thereof.First, because the stroke regulating mechanism that vibrates is comparatively complicated, require high to manufacture and installation accuracy, often easily cause the stroke at two ends, same tamping equipment left and right inconsistent during adjustment, cause tamping equipment normally to work; And more seriously two tamping equipment in reciprocating motion, because the stroke of forward and backward part of vibrating is different, the direction of motion is not contrary, it must be made to produce larger unbalance inertia force in the course of the work, thus negative interference and bad vibration effect are produced to screed, cause the spreading quality of the decline of machine functional performance and road pavement to reduce.Therefore, how effectively eliminate the inertia force that tamping equipment produces, be the problem paid special attention to of numerous paver manufacturer and technological difficulties always.
