Description

Buffer device for pile driver follow-up frame

Technical Field

The utility model relates to a pile driver specifically indicates a buffer for pile driver follow-up frame.

Background

The pile driver is at the in-process of pile, beats and pulls out the hammer carrier and can vibrate, and follow-up frame can beat and pull out the vibration of hammer carrier and vibrations, and traditional follow-up frame does not have the absorbing function, can influence the behavior of pile driver after using for a long time.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, a buffer for pile driver follow-up frame is provided.

In order to solve the technical problem, the utility model provides a technical scheme is a pile driver is buffer for follow-up frame: the follow-up frame is connected with the lifting guide rail in a sliding mode, the chain is arranged around the lifting guide rail, the two ends of the chain are fixedly connected with the upper end and the lower end of the follow-up frame, the hammer frame is fixed on the follow-up frame, first through holes are symmetrically formed in the two ends of the follow-up frame, connecting rods are arranged in the first through holes in a sliding mode, connecting blocks are arranged on the connecting rods located on the outer side of the follow-up frame, the connecting blocks are connected with the chain, first gaskets, springs and second gaskets are sleeved on the connecting rods located on the inner side of the follow-up frame, the first gaskets are in contact with the inner wall of the follow-up frame, the springs are located between the first gaskets and the second gaskets, nuts are arranged on the connecting rods, the nuts and the connecting rods are fixed through threaded connections, and the nuts play a role of extruding the.

As a refinement, the spring is a compression spring.

As an improvement, a second through hole is formed in the follow-up frame.

Compared with the prior art, the utility model the advantage lie in: the spring in the follow-up frame plays the effect of shock attenuation, increases the stability of the work of pile driver, improves the life of pile driver's use.
