Description
The technical field is as follows:
the invention relates to a rotation adjusting type eccentric vibration structure of a vibratory roller, and belongs to the technical field of road building machinery.
Background art:
the vibratory roller uses its own gravity and vibration to compact various building and road building materials. In road construction, vibratory rollers are widely used to optimally compact various non-sticky soils, crushed stones, crushed stone mixtures and various asphalt concretes. The vibratory roller mainly comprises 4 parts of a vibratory steel wheel, an excitation mechanism, a vibration damping system, a traveling mechanism and the like. The weight of the vibration steel wheel accounts for about 80 percent of the vibration weight (participating in the vibration weight), the vibration steel wheel is formed by welding and processing steel wheel rings, radial plates and the like, deformation resistance and wear resistance are required, certain rigidity, strength and roundness are required, and the requirements of roadbed, pavement flatness, strength and compaction are met. The vibration exciting mechanism is composed of vibration shaft, vibration bearing, fixed and movable eccentric blocks, etc. and is installed in the vibration chamber formed by flange plates (the flange plates are fixed on the steel wheel web plate by bolts).
The eccentric quick mechanism of vibration exciter of vibrated roller on the existing market is undersized oversize, be unfavorable for the installation, and in actual work progress, to the highway section of different road beds, it is different to the tolerance capacity of ramming, if ramming force is too big, then make the road bed broken easily, ramming force undersize, the road bed that is difficult to stabilize again, consequently, vibrated roller need apply different amplitudes to particular case, obviously, the eccentric vibrating mechanism of vibrated roller of current vibrated roller can not satisfy actual need, need to improve urgently.
In the prior art, chinese patent No. ZL201710030207.7 discloses an eccentric vibration device of a road roller and an arrangement structure thereof, which includes a vibration shaft, and further includes a movable eccentric block set disposed on the vibration shaft, the movable eccentric block set includes a movable eccentric block, a limit ring and a fixed key; the limiting ring is fixed on the vibrating shaft through a fixed key, the movable eccentric block is provided with a limiting groove matched with a limiting lug on the limiting ring, and the central angle of the limiting groove is equal to or larger than that of the limiting lug; when the central angle of the limiting groove is larger than that of the limiting convex block, the limiting groove is matched with the limiting convex block, so that when the vibration shaft rotates forwards or backwards, the movable eccentric block is respectively provided with two vibration limit positions. The invention greatly simplifies the structure of the movable eccentric block, reduces the manufacturing and mounting difficulty of the eccentric block, and simultaneously, the movable eccentric block is integrally formed, so the movable eccentric block is not easy to damage when in use and keeps higher stability and reliability when in work. Meanwhile, chinese patent No. ZL200910116473.7 discloses an eccentric vibration mechanism of a vibratory roller, including a vibration shaft, the cover is equipped with a fixed eccentric block rotating along with the vibration shaft, the side of the fixed eccentric block is equipped with a movable eccentric block, the fixed eccentric block and the movable eccentric block cooperate to make the vibration mechanism respectively in two vibration states of high and low amplitude, because the movable eccentric block is arranged at the side of the fixed eccentric block, when the vibration shaft rotates positively and negatively, the fixed eccentric block rotates positively and reversely along with the vibration shaft, the movable eccentric block rotates under the driving of the fixed eccentric block, and simultaneously, the vibration mechanism cooperates with the fixed eccentric block to realize two vibration states of high and low amplitude, thereby making the vibratory roller can better adapt to road sections of different roadbeds, and greatly improving the production efficiency of the vibratory roller.
However, in the existing technical solutions, the amplitude of the vibratory roller is mostly fixed and cannot be adjusted, and in the technical solution disclosed in the above-mentioned chinese patent No. ZL200910116473.7, only two vibration states, namely high and low amplitude, can be adjusted; in the above-mentioned chinese patent No. ZL201710030207.7, the movable eccentric mass has two vibration limit positions, and also has only two amplitude vibration states. In the actual work progress, to the highway section of different road beds, its tolerance to the ramming is different, if the ramming force is too big, then makes the road bed breakage easily, and the ramming force undersize is difficult to again stabilize the road bed, therefore vibrated roller need exert different amplitudes to the particular case. The prior art scheme gathers, and although the movable eccentric block capable of adjusting the amplitude of the vibratory roller appears, the structure of the existing movable eccentric block is complex, so that the installation is difficult, the adjustment is difficult, and meanwhile, the complex movable eccentric block structure is easy to damage during vibration. Obviously, the eccentric vibration mechanism of the existing vibratory roller cannot meet the actual requirement, and needs to be improved urgently.
