Description

Technical Field

[0001] The utility model relates to the technical field of loading and buffering, in particular to an elastic cement impact loading buffer. Background Art

[0002] Buffers are important components in mechanical equipment. They slow down rigid collisions during equipment operation, delay the action time of impact loads, and absorb and convert the energy of impact loads. Elastic cement buffers are a high-performance buffer that was first used by the European Railway Union System in the early 1980s. They are highly favored because of their shock-absorbing buffer performance and ideal service life, overcoming the shortcomings of poor shock-absorbing performance and short service life of hydraulic buffers, spring buffers and vulcanized rubber buffers.

[0003] At present, the elastic cement impact loading buffer in the prior art is usually buffered by internal elastic cement. When in use, since the buffer buffers the equipment, the buffer needs to be fixed around the equipment, and the connection structure of the buffer needs to correspond to the equipment. The connection of the equipment is set in advance, so the connection structure of the buffer needs to be adjusted to correspond to the equipment. There is a problem that the position of the buffer connection structure cannot be easily adjusted. In addition, when in use, the inside of the buffer is buffered by elastic cement, and the elastic cement will cause loss after repeated use. To add elastic cement, the buffer needs to be completely disassembled for addition, the operation is complicated, and there is a problem that the elastic cement cannot be easily added.
