Description
Technical field
The utility model is related to hydraulic pile driver equipment manufacturing technology field, more particularly to a kind of hydraulic hammer hammer body and pile cover
Annular connection buffer structure.
Background technology
Since above ground structure will be built on the ground, ground will bear prodigious pressure, need to ensure that ground has enough
Renitent intensity, and this is often difficult to realize, therefore the ground for bearing building must just be reinforced or be changed
Mode is born on kind ground, so just need to drive piles on ground, allow building most of weight by stake pass to ground with
Under very deep position because the ground of this position is more much bigger than ground ability to bear.
Currently, in building construction process, in order to keep building basis firm, it is often necessary to be set using pile foundation construction
Standby, pile foundation construction equipment in the prior art mainly will hammer core into shape by hydraulic device and be promoted to quick release after certain altitude,
It after storing enough gravitional force for piling, is directly acted on the anvil block or pile cover of hydraulic hammer, is led in a manner of falling impacts
The direct effect for crossing hammer core and anvil block does work to target pile body, the stake of the materials such as timber or stone mar is pounded into ground depths.Due to
Hydraulic hammer hammer core is very big to the active force of anvil block, and the time of transmission is very short, and anvil block easy tos produce vibration, if conducting to hydraulic hammer
In hammer body and pile cover, it is easy to damage hydraulic hammer hammer body and pile cover, and then reduce the service life of hydraulic hammer.
Vibration to solve to generate after hydraulic hammer hammer body acts on effective object is easy to ask what hammer body itself damaged
Topic, the utility application that number of patent application is 201710735454.7《A kind of hydraulic hammer protective device and to hydraulic hammer
Into the means of defence of row buffering》, by the way that buffer gear is arranged between oil cylinder and weight, delayed by spring and the dual of bolster
Punching combination, makes the entire action process of weight effectively be buffered；In the period that weight falls, rebounds, have enough or necessary
Space and technical measures, ensure that cylinder piston rod continues deceleration downlink, so that piston rod is had neither part nor lot in weight rebound and process or only join
With the later stage of rebound process, the later stage rebound acceleration for the process that rebounds significantly is decayed, or even tends to 0, simultaneously because evading
Or significantly reduce the adverse effect of parts of the weight rebound to cylinder piston rod or mounted on piston rod, cylinder piston rod and peace
Do not rebound mounted in the parts of piston rod or slightly rebound, not only protect oil cylinder, also protect rack and with rack is associated sets
Standby other parts, significantly improve the stability of whole device, improve the service life of each part of appliance indirectly.Above-mentioned buffering knot
Structure protects the more spare parts such as hookup, spring, washer, connecting piece, gland, fastener, bolster, washer, lock washer,
Each spare part assists work to provide pooling feature for hydraulic hammer hammer body simultaneously, and structure design is also complex.It should be due to its zero group
Number of packages amount is more, assembly relation is complicated, overall weight is also larger, high speed, high frequency time piling work during, part spare part
It is susceptible to fatigue, damage, so as to cause the global failure of the buffer structure, easily the overall structure of hydraulic hammer is damaged,
Also it is unfavorable for the repair and replacement in later stage simultaneously.
Therefore, it is necessary to existing way to play for time and structure, carry out new Curve guide impeller.
