The swing buffer structure of present case converts pitch arc swing energy into linear motion energy, just so can absorb pitch arc wobbling energy through the buffer is indirect, and the buffer openly receives the buffering impact, can effectively cushion the life-span that can prolong the buffer again at the speed reduction.

Description

Swing buffer structure

Technical Field

The utility model relates to a swing buffer structure.

Background

It is known that in order to make the operation of the equipment more stable and reliable and prolong the service life of the equipment, damping devices (generally adopting hydraulic dampers) are installed at the original position and the final position of an equipment operating mechanism as required for absorbing the impact energy of the movement, and the effect is particularly obvious for the mechanism which moves at a high speed under heavy load. However, due to structural limitations (small allowed lateral impact angle, within 5 °), the hydraulic shock absorber is more applicable to damping of linear motion mechanisms or mechanisms close to linear motion, and has poor applicability to damping of mechanisms swinging in an arc, and is easy to damage a damping head and a sealing member, thereby causing oil leakage and failure. The prior mechanism which meets the arc swing can only do front end or tail end deceleration processing on a driver by buffering, but the effect is not ideal.

Fig. 1 is a schematic diagram of conventional swing buffering, as shown in fig. 1, a hydraulic buffer 3 is directly installed above a set of mechanism swinging in an arc, when a driving cylinder 1 moves to drive a swing crank 2 to swing up to a position close to a final position, a head of the hydraulic buffer 3 starts to contact a buffer seat plate 5 fixed on a mounting bracket 4, at this time, a buffer body and the buffer seat plate 5 are not in a perpendicular state but form a certain angle, when the movement continues, the head of the hydraulic buffer 3 retracts and simultaneously slides in a friction manner with the buffer seat plate 5 to adapt to the change of the angle and distance until the angle and the distance are perpendicular, as a rod part of the hydraulic buffer 3 continuously receives a lateral force, a rod part sealing ring is easy to laterally wear and leak oil, and a head silencing sleeve is worn, and finally the hydraulic buffer.
