Description
Technical field
The present invention relates to a kind of diesel hammer, more specifically to a kind of a kind of following for diesel hammer for pile foundation construction
Ring water cooling system.
Background technology
The modern times such as port, man-made island construction, bridge spanning the sea, oil drilling platform and marine wind electric field are built recently as off-lying sea
The need for ocean engineering foundation construction, have that blow energy is big, simple to operate, easy to maintenance, operation based on large-tonnage diesel hammer
The features such as efficiency high and high cost performance, still find broad application.But, with the continuous propulsion of ocean engineering project, to big
The pile foundation construction of type marine engineering construction project proposes higher bearing capacity requirement, and it is bigger that pile foundation construction employs a footpath
Steel-pipe pile, and pile sinking depth tends to more Shenzhen Development Bank, such as current pile sinking stake footpath has reached Φ 1.6m, Φ 1.8m, 2.0m, Φ 2.2m
And Φ 2.5m, and pile sinking depth, also respectively more than 60m, 70m, 80m and more than 100m, diesel hammer is also increasingly towards large-scale therewith
The direction of change is developed, and demand of the in the market to blow energy in more than 830kNm super-tonnage diesel hammer further increases.
Now, air-cooled diesel pile hammer is when carrying out construction operation, and upper piston comes off and free-falling from undercarriage,
When upper piston falls the suction/exhousting hole by lower cylinder, start to compress the air in lower cylinder, when living under upper piston head impact
Plug shock surface simultaneously makes diesel oil atomization be splashed in combustion chamber, and diesel hammer lays stake；Mist of oil in combustion chamber is ignited blast, institute
The explosive force of generation continues down to beat stake, and upper piston is bounced upwards, then upper piston setting point fuel spray again, so
Move in circles, realize the operation of piling construction.In order to improve the anti-wear performance of lower cylinder, extend its service life, in lower cylinder
Cylinder jacket is inlaid with vivo, cylinder jacket is embedded in cylinder holes corresponding with fin position.
In air-cooled diesel hammer in pile sinking operation process, diesel oil makes the temperature that outer wall of combustion chamber is produced in burning detonation inside
Degree is typically up to more than 300 DEG C, and these heats need outwardly to distribute by the lower cylinder block of diesel hammer.Current bavin
The cooling radiator structure of oil hammer is that multi-disc fin is provided with the bottom of lower cylinder mostly, and lower cylinder passes through these fin and sky
Gas carries out heat convection, but because diesel hammer subjects huge impact shock, lower cylinder body often has thicker wall thickness, especially
Thicker for large-sized diesel hammer lower cylinder body wall thickness, it radiates difficult, and the heat transfer of current fin air-cooled structure, radiating effect are very not
Ideal, and be vulnerable to the influence of external condition, the factor such as following cylinder ambient air temperature is higher, wind speed is smaller, and make lower vapour
Cylinder heat can not disperse in time, the hurried rise of hammer body temperature is caused many harm.First, lower cylinder temperature is too high, meeting
Cause the advanced ignition of pile hammer, fuel oil explosion energy is converted to the hammer action to stake, imitates pile hammer with being unable to the term of validity
Rate significantly declines, in addition cause can not normal work, have to stop piling, wait after the cooling of diesel oil hammer body that row is started shipment again.Its
Secondary, lower cylinder temperature is too high, and the Frotteurism for not only resulting in cylinder inner wall and piston space is deteriorated, and cylinder block material intensity drops
Low, plasticity increase, abrasion aggravation, the high temperature and high pressure gas produced by blast are acted on cylinder, piston and piston ring, cause gas
The cavitation erosion of cylinder, piston and piston ring, aggravates its corrosive damage, and the part of cylinder, piston and piston ring can be caused to melt when serious
Change and pull, or even form Cylinder sticking, have a strong impact on the service life of diesel hammer, influence the construction speed and operation effect of pile foundation engineering
Rate.Raising, stake diameter especially in pile monkey tonnage and in the case of the continuous increase of length, per the increasing of the continuous hammer number of pile
Many, vapour cylinder temperature raises the damage probability for faster more aggravating cylinder, piston and piston ring.So, air-cooled diesel hammer is difficult
To meet the use requirement of modern marine engineering foundation construction.
