Description
Technical field
The present invention relates to the tubular diesel pile hammer for pile foundation engineering construction, relate in particular to the lower cylinder body with water-cooling apparatus tubular diesel pile hammer, and the tubular diesel pile hammer with this lower cylinder body.
Background technology
Tubular diesel pile hammer is to utilize fuel oil explosion energy upwards to promote upper piston move back and forth to produce to impact, and carries out impact pile driving; Advantages such as it is large with its impact force, operating efficiency is high, reliability is strong, operating maintenance is convenient and being used widely.Along with the needs of the foundation constructions such as development, particularly modern marine engineering, bridge spanning the sea, oil drilling platform and marine wind electric field of China's economic construction, tubular diesel pile hammer is more and more towards the future development maximizing in recent years.
Tubular diesel pile hammer is when carrying out construction operation, upper piston comes off and free-falling from undercarriage, when upper piston falls to passing through the suction/exhousting hole of lower cylinder, start to compress the air in lower cylinder, when upper piston head impact lower piston shock surface and diesel oil atomization is splashed in combustion chamber, stake is laid simultaneously; Mist of oil in combustion chamber is lighted blast, and the explosive force that produces continues stake down to beat, and makes upwards spring of upper piston, and then upper piston setting point fuel spray again, so moves in circles, and realizes piling construction operation.
Tubular diesel pile hammer is in impact pile driving process, and the amount of heat that diesel combustion blast produces, need to outwards distribute by the lower cylinder surface of pile hammer.Otherwise lower cylinder heat can not leave in time, must make hammer body temperature sharply raise and cause many harm, first lower cylinder excess Temperature, can cause the advanced ignition of pile hammer, fuel oil explosion energy can not be converted to period of validity the hammer action to stake, the efficiency that makes to drive piles significantly declines, and even causes and cannot normally work, and after the wait piling hammer body of having to stop drive piles is cooling, row is started shipment again.While lower cylinder excess Temperature, not only can cause the Frotteurism variation of cylinder inner wall and piston space, and cylinder block material strength decreased, plasticity increases, wearing and tearing aggravation, the high temperature and high pressure gas that blast produces acts on cylinder, piston wall, cause the cavitation erosion of cylinder, piston, aggravate its corrosivity and damage, when serious, can cause the local melting of cylinder, piston and pull, even form Cylinder sticking, have a strong impact on the application life of pile hammer.
In order to strengthen the radiating efficiency of pile hammer lower cylinder body, tubular diesel pile hammer lower cylinder and cooling unit thereof are nothing more than two kinds of form of structure at present.A kind of is to adopt steel-pipe welding structure, as disclosed tubular diesel pile hammer in Chinese patent " the heavier-duty cooling jacket of diesel pile hammer ", the patent No. 90215299.8, it is the water jacket housing of the thin shell structures of the external welding of lower cylinder made at steel pipe and form cooling water tank, the passage components such as suction and exhaust ports, atomizer installing port and lubrication oil inlet that lead to lower cylinder inwall, also will be welded to each other with it through tank shell and cylinder block.Another kind of structure is the casting lower cylinder body adopting with air-cooled annular fin.
Yet, along with putting into operation of the Larger Engineering Projects such as offshore drilling platforms, wind generator facility, deep water port harbour, bridge spanning the sea, the pile body degree of depth, diameter with and supporting capacity all towards maximization future development, cartridge type pile hammer is when meeting the harsh job requirements such as stratum is hard, complicated, difficulty of construction is large, the specification tonnage of pile hammer and hitting power also correspondingly have great raising, and the continuous hammer number of every pile also must increase.It can produce huge heat in piling process, and very strong impact shock, under this bad working environments, only rely on fin and air on lower cylinder body to carry out heat convection, is obviously the radiating effect that can not meet pile hammer; And the welding cisten mechanism of employing steel, water jacket housing, suction and exhaust ports etc. are located attachment weld under the effect of continuous high temperature and impact shock, weld seam will soon Yin Gaowen and vibrating fatigue and ftractureing, the weld seam that ftractures on the one hand can make cooling water leakage and lose water-cooled effect, now water jacket hinders again the air cooling effect of lower cylinder, pile hammer damage often will occur at short notice it is scrapped; The weld seam that ftractures on the other hand also can make water liquid locate in weld seam inflow lower cylinder body along suction and exhaust ports, pouring orifice etc., and the lighter causes pile hammer blow efficiency decline or quit work, and severe one can ftracture until scrap because of the inhomogeneous cooling expansion of inboard wall of cylinder block.Therefore, large-scale solid bowl type diesel pile hammer in the course of the work be reliably cooled to puzzlement industry one technical barrier.
Summary of the invention
