Description
Technical field
The present invention relates to piling machine equipment manufacturing technology field, in particular to a kind of diesel hammer hammer body and pile cover cushioning control
Method and connection buffer structure.
Background technique
Diesel hammer is one kind of building machinery, is the conventional machinery equipment in construction, is mainly pushed away using fuel oil explosion
Piston moves back and forth and impact pile driving, and piston weight is from several hundred kilograms to several tons.With the suitable weight tap of hammer piling.If weight
Bang then hammers function and is largely absorbed by pile body, and stake is not easy to squeeze into, and pile crown is easily broken.Hammer weight preferably has certain with stake weight
Ratio, or control hammering stress, are broken to prevent stake.Pile frame is to support pile body and pile monkey, and the direction of stake is guided in pile driving process,
And enable pile monkey along the pile driving equipment of desired direction impact.
Current hammer class building machinery is to solve hydraulic hammer hammer body to be easy to hammer the vibration generated after effective object effect
The problem of body itself damages, application for a patent for invention " a kind of hydraulic hammer protection that number of patent application is 201710735454.7
Device and the means of defence that hydraulic hammer is buffered ", by the way that buffer gear is arranged between oil cylinder and weight, by spring and
The double buffering of bolster is combined, and buffers the entire action process of weight effectively；In the time that weight falls, rebounds
Section, has enough or necessary space and technical measures, guarantees that cylinder piston rod continues deceleration downlink, piston rod is made to have neither part nor lot in weight
The later period rebound acceleration in rebound process or the later period for being only involved in rebound process, the process that rebounds significantly is decayed, or even is tended to
0, simultaneously because evade or significantly reduce the adverse effect that weight rebounds to cylinder piston rod or the parts for being mounted on piston rod,
Cylinder piston rod and the parts for being mounted on piston rod do not rebound or slightly rebound, and not only protect oil cylinder, also protect rack and
With the associated equipment other parts of rack, the stability of whole device is significantly improved, that improves each part of appliance indirectly uses the longevity
Life.Above-mentioned buffer structure protects hookup, spring, washer, connecting piece, gland, fastener, bolster, washer, lock washer
Etc. more spare part, each spare part assists work to provide pooling feature for hydraulic hammer hammer body simultaneously, and structure design is also more multiple
It is miscellaneous.It should be worked in high speed, the piling of high frequency time since its spare part quantity is more, assembly relation is complicated, overall weight is also larger
Cheng Zhong, part spare part is easy to appear fatigue, damage, so as to cause the global failure of the buffer structure, easily to the whole of hydraulic hammer
Body structure damages, while being also unfavorable for the maintenance and replacement in later period.
Summary of the invention
Present invention aims at provide a kind of diesel hammer hammer body and pile cover buffering controlled for the above-mentioned deficiency of the prior art
Method processed and the connection buffer structure for implementing this method focus on the structure design for optimizing the prior art and control step
