Description
Technical field
The invention belongs to piling machinery technical field, more particularly to firm hydraulic pile equipment for building.
Background technology
Hydraulic pile hammer is to overcome a kind of New engineering machinery that diesel hammer noise is big, has pollution to occur, extensively should
For bridge, industry, the pile foundation construction built.Tup pumps in its pile monkey hammer systems, hits pallet, transmits
Impulsive force is to stake.
In the prior art, hydraulic pile hammer tup is that a monoblock forged steel is processed into cylinder or cuboid, due to beating
Pile monkey work mainly utilizes the gravitional force of tup so that tup weight is larger.Monoblock tup is processed to lathe bearing capacity
There are particular/special requirement, high processing costs；The problem of bigger, is, because the gravitional force of tup is produced by the impact with rigid pallet
The form of raw stress wave passes to rigid pile cover, then passes to the stake beaten, and causes stake difficult when the stake beaten runs into rigid foundation
During squeezing into ground, stress crest value caused by tup impact is very high, and the time of transmission is very short, the efficiency of this energy transmission
It is low, it is easier to which that stake is broken.This very high stress crest can also produce very big destructive power to the part of tup in itself simultaneously.
Such as application number 201410673660.6 is used the invention discloses a kind of hydraulic pile hammer and combines tup, for pile foundation
The pile monkey hammer systems of hydraulic pile hammer, the tup include the hammer body of an inner hollow, the bottom of the hammer body in plinth construction
Portion sets impact head, top connection cylinder piston rod, and the hollow cavity inside of the hammer body is filled with metallic particles filler.Institute
State hammer body and be superimposed connection by several metallic plates, wherein the lower plate positioned at bottom and the upper plate closing positioned at top, positioned at centre
Some intermediate plates be frame shape hollow sheeting, after superposition formed hammer body inner hollow cavity.The present invention can effectively improve tup punching
Stress wave when hitting, the peak value of stress wave is reduced to recommended minimum value and extends passing time of the stress wave in peak state,
While improving impact energy and obtaining transmission efficiency and Piling speed, the impulsive force that pile hammer and stake are born is reduced, improves piling
In the life-span of hammer, stake is protected not broken.
The inventors discovered that above-mentioned patent has the following disadvantages in actual use：The metal being filled in hollow cavity
Granule filler is excessively scattered, and caused inertial impact force in real time is pressed downward under its effect of inertia and is excessively disperseed, causes institute
The impulsive force that main piling can be played is weaker；The metallic particles filler being filled in hollow cavity is excessively intensive, Zhi Jiansuo
It is smaller to have space, cause by be pressed downward under effect of inertia in real time, the inertial impact force that metallic particles filler plays compared with
It is small and because the scattered of inertial impact force leads to not play the impulsive force effectively driven piles.
Such as application number 201410674856.7 is carrying the invention discloses a kind of hydraulic pile hammer blank-run prevention buffer unit
Hammer cylinder block bottom is installed with integrated valve seat, and the integrated valve base cavity is arranged with block on the piston rod successively from top to bottom
And guide sleeve, the guide sleeve are fixed on integrated seat bottom portion, its inner ring is slidably matched with piston rod, the outer ring of the block and
Inner ring is slidably matched with the inwall and piston rod of integrated valve seat respectively, work of the cushion chamber between block and guide sleeve in overflow valve
Back pressure is set up under, the resistance that moves downward to block is produced in the lower end area of block by the back pressure effect, finally makes work
Stopper rod stops moving downward, and absorbs tup and is impacted because of empty beat caused by equipment, the service life of equipment of extension, ensures construction
Safety.
Needs constantly repeat to drive piles above-mentioned patent is not easy to cause the stake squeeze into ground when running into rigid foundation there is also piling when
The problem of operation is longer.
Then, in view of this, improvement is studied for existing structure and missing, there is provided firm hydraulic pile for building
Equipment, to reach the purpose for having more more practical value.
The content of the invention
