Description
Technical field
The utility model relates to a kind of diesel hammer, more particularly, relates to a kind of circulating water cooling system of a kind of diesel hammer for pile foundation construction.
Background technology
The needs of the modern marine engineering foundation constructions such as port, man-made island construction, bridge spanning the sea, oil drilling platform and marine wind electric field are built in recent years along with off-lying sea, have based on large-tonnage diesel hammer that blow energy is large, simple to operate, easy to maintenance, operating efficiency is high and cost performance high, still find broad application.But, along with the continuous propelling of ocean engineering project, higher supporting capacity requirement is proposed to the pile foundation construction of Large marine engineering construction project, pile foundation construction have employed the larger steel pipe pile in a footpath, and the pile sinking degree of depth tends to more Shenzhen Development Bank, such as pile sinking stake footpath has reached Φ 1.6m at present, Φ 1.8m, 2.0m, Φ 2.2m and Φ 2.5m, and the pile sinking degree of depth is also respectively more than 60m, 70m, 80m and more than 100m, diesel hammer is also more and more towards the future development maximized thereupon, market increases further to the demand of blow energy at the super-tonnage diesel hammer of more than 830kNm.
Now, air-cooled diesel pile hammer is when carrying out construction operation, upper piston comes off and free-falling from undercarriage, when upper piston falls through the suction/exhousting hole of lower cylinder, start to compress the air in lower cylinder, make diesel oil atomization be splashed in combustion chamber when upper piston head impact lower piston shock surface, stake is laid by diesel hammer; Mist of oil in combustion chamber is lighted blast, and the explosive force produced continues stake down to beat, and upper piston is upwards bounced, and then upper piston setting point fuel spray again, so moves in circles, realize the operation of piling construction.In order to improve the anti-wear performance of lower cylinder, extending its application life, in lower cylinder body, being inlaid with cylinder jacket, cylinder jacket is embedded in the cylinder holes corresponding to fin position.
At air-cooled diesel hammer in pile sinking operation process, the temperature that diesel oil makes outer wall of combustion chamber produce in combustion chamber implode generally will reach more than 300 DEG C, and these caloric requirements are outwardly distributed by the lower cylinder block of diesel hammer.The cooling heat dissipation structure of current diesel hammer is be provided with multi-disc fin in the bottom of lower cylinder mostly, lower cylinder carries out heat convection by these fin and air, 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, its difficulty of dispelling the heat, the heat transfer of current fin air-cooled structure, radiating effect is very undesirable, and be vulnerable to the impact of external condition, following cylinder ambient air temperature is higher, the factors such as wind speed is less, and lower cylinder heat can not be left in time, the hurried rising of hammer body temperature must be made to cause many harm.First, lower cylinder temperature is too high, 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, pile hammer efficiency is significantly declined, even causes and cannot normally work, have to stop piling, after waiting for the cooling of diesel oil hammer body, row is started shipment again.Secondly, lower cylinder temperature is too high, the Frotteurism of cylinder inner wall and piston space not only can be caused to be deteriorated, and cylinder block material intensity reduces, plasticity increases, wearing and tearing aggravation, the high temperature and high pressure gas produced that explodes acts on cylinder, piston and piston ring, cause the cavitation erosion of cylinder, piston and piston ring, aggravate its corrosive damage, the local melting of cylinder, piston and piston ring can be caused time serious and pull, even forming Cylinder sticking, have a strong impact on the application life of diesel hammer, affect construction speed and the operating efficiency of pile foundation engineering.Especially, in the continuous increase situation of the raising of pile monkey tonnage, stake diameter and length, increasing of the continuous hammer number of every pile, vapour cylinder temperature raises faster, more aggravates the damage probability of cylinder, piston and piston ring.Like this, air-cooled diesel hammer has been difficult to the instructions for use meeting the construction of modern marine engineering foundation.
