Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of buffer device, in particular to a ring buffer. BACKGROUND

[0002] The buffer is used between the two ends of the machine to alleviate the impact force between the machines. The buffer is divided into rigid buffer and spring buffer. The rigid buffer has simple structure, but the buffering effect is poor, the machine is easily damaged, and the service life of the device is shortened, and it is only suitable for small machines. The spring buffer can generally only buffer the impact of collision, but cannot buffer the impact of traction. The coupler for connecting the machines into a train and transmitting the traction force should have sufficient reliability and simple operation to ensure the safety of the machine during marshalling and disassembly. After the machine is connected, there must be a certain amount of free movement in the vertical and horizontal directions, so that the machine can run freely in the curve with small radius and the inclined roadway with inconsistent slope. The coupler is divided into ordinary type and automatic type according to its function mode, and is divided into rotatable and non-rotatable according to its structure. The ordinary non-rotatable coupler has single ring chain and three ring chain, which is suitable for the connection of dump truck and fixed car type machine. The rotatable coupler has universal chain, which is used when the fixed car type machine is unloaded in the circular tipping machine without uncoupling.
