Lifting chain buffer structure for vibroseis

The utility model provides a lifting chain buffer structure for a vibroseis. The lifting chain buffer structure comprises a flat plate, a hammer body, an air spring, a pressing plate frame, a chain, a spring, a guide column, an oil cylinder and a carrier frame, a piston rod of the hammer body is rigidly connected with the flat plate, the lower end of the chain is fixed to the flat plate through a pin shaft, and the other end of the chain penetrates through the pressing plate frame, is arranged in the spring in a penetrating mode and is fixed to the top end of the spring. The bottom end of the spring is fixed to the pressing plate frame, and the air spring is fixed between the flat plate and the pressing plate frame. The special-shaped chain still serves as a connecting mechanism of the carrier frame and the flat plate, and the spring provides continuous supporting force for the chain. Due to the existence of the rigidity characteristic of the spring, the chain can still be kept in a straightened state when th
