The purpose of this utility model be to provide a kind of and do not shut down when changing operating mode, pinch roller vibration and oscillation tripper simple to operate.
The purpose of this utility model is achieved in that the side at jackshaft is connected with short eccentric block case, and short wobbler shaft is installed in the short eccentric block case; Opposite side is connected with long eccentric block case, and long wobbler shaft is installed in the long eccentric block case.
Short wobbler shaft is that a wobbler shaft is arranged, be connected with large and small eccentric block on the wobbler shaft, wobbler shaft and large eccentricity piece fuse, and the large eccentricity piece is formed by two, and the lower end is connected with wobbler shaft simultaneously, the upper end is from being connected, have a bearing pin to pass two large eccentricity pieces at the large eccentricity block edge, bearing pin and large eccentricity piece are connected as a single entity, and form a groove between two, be connected with the small eccentricity piece on the wobbler shaft in groove, the small eccentricity piece can rotate on wobbler shaft; Long wobbler shaft also has a wobbler shaft, be connected with large and small eccentric block on the wobbler shaft, the large eccentricity piece can rotate on wobbler shaft, and the large eccentricity piece is formed by two, and the lower end is connected with wobbler shaft simultaneously, the upper end is from being connected, have a bearing pin to pass two large eccentricity pieces at the large eccentricity block edge, bearing pin and large eccentricity piece are connected as a single entity, and form a groove between two, be connected with the small eccentricity piece on the wobbler shaft in groove, small eccentricity piece and wobbler shaft connect as one.
Owing to adopted such scheme, a large eccentricity square eccentric block is fixed eccentric block (initiatively), and little inclined to one side square eccentric block is movable eccentric block; Another axle then is that small eccentricity square eccentric block is fixed eccentric block (initiatively), and the large eccentricity piece is movable eccentric block, when in pinch roller it after operating mode installs by vibration or vibration, the main technical requirements of vibration and oscillation operation is changed with the electrical control realization when driving its synchronous rotating and just can realize pushing the physical circuit face by hydraulic motor, has reached the purpose of this utility model.This tripper structure is ingenious, vibration or vibration conversion are convenient, be applied in the tandem roller, can give full play to vibration and oscillation operation advantage separately like this by automatically controlled random transition vibration or vibration operation, remedy its shortcoming, simultaneously it has reduced material such as compacting bituminous concrete and must give and pressing and the final pressure operation, has reduced construction costs, has improved the machinery utilization rate, realize a tractor serves several purposes, improved engineering application life.
Be described further in conjunction with the embodiments with reference to the accompanying drawings below.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the short wobbler shaft structure chart of the utility model.
Fig. 3 is the long eccentric block structure chart of the utility model.
