Description
Technical field
The utility model relates to the tubular diesel pile hammer for construction work pile foundation construction, particularly relates to the pressure cooling of tubular diesel pile hammer cylinder chamber.
Background technology
Tubular diesel pile hammer (hereinafter referred to as cylinder hammer) is a kind of pile driving equipment of construction work pile foundation construction, and due to it, to have impact force large, and operating efficiency is high, and range of applicability is wide, advantages such as easy maintenance and being used widely.Cylinder hammer is the energy utilizing fuel oil (diesel oil) blast to produce, and upwardly upper piston, produces potential energy, then fall, and produces impact force, realizes the construction equipment of paddle type mill piling.In recent years along with the development of China's economic construction, the needs of the particularly foundation construction such as modern marine engineering, bridge spanning the sea, oil drilling platform and marine wind electric field, tubular diesel pile hammer is more and more towards the future development maximized.
Cylinder hammer construction operation starts, upper piston comes off and free-falling from undercarriage, when upper piston falls through the suction and exhaust ports of lower cylinder, start to compress the air be closed in lower cylinder, make diesel oil atomization be splashed in combustion chamber when upper piston head impact lower piston shock surface, stake is laid simultaneously; Mist of oil in combustion chamber mixes with compressed air is lighted blast, the explosive force produced continues stake down to beat, and upper piston upsprings and skips to certain altitude under explosive force effect simultaneously, and then upper piston falls again, so move in circles, realize piling construction operation.
In above process, diesel combustion explodes the amount of heat produced, and the inner chamber exterior surface of the lower cylinder block mainly hammered into shape by cylinder is distributed, and to burn the balance of interior temperature to keep lower cylinder.The cooling heat dissipation structure of current cylinder hammer is be provided with multi-disc fin in the bottom of lower cylinder external surface mostly, lower cylinder carries out heat convection by these fin and air, but the radiating effect of this natural air cooled structure is very undesirable, one is to meet intensity, the casing wall thickness of lower cylinder is all very thick, and inner chamber heat is not easily transmitted to external surface; Two is the impacts being subject to external condition, the factors such as following cylinder ambient air temperature is higher, wind speed is less.And lower cylinder heat can not leave in time, the hurried rising of cavity temperature in cylinder block must be made to cause many harm, first descend cylinder temperature too high, cylinder can be caused to hammer fuel oil advanced ignition into shape, upper piston and lower piston can not bump against, and fuel oil explosion energy can not be converted to period of validity the percussion to stake, and piling efficiency is significantly declined, even cause and cannot normally work, after having to stop piling waiting for the cooling of cylinder hammer hammer body, row is started shipment again.With cylinder temperature is too high at present, 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 lower cylinder inner wall, piston end surface, cause cylinder inner wall surface, piston face cavitation erosion, aggravate its corrosive damage, the local melting of cylinder, piston can be caused time serious and pull, even form Cylinder sticking, have a strong impact on the application life of cylinder hammer.Especially along with the increase day by day of stake diameter and length, blow energy is more and more higher, and cylinder hammer tonnage is also higher, increasing of the continuous hammer number of every pile, and cylinder temperature raises faster.The tubular diesel pile hammer of current natural air cooled mode has been difficult to meet basic engineering construction and has require that.
Utility model content
For the above-mentioned deficiency existing for prior art, the pressure inner chamber Wind-cooling type tubular diesel pile hammer that technical problem to be solved in the utility model is to provide a kind ofly forces to disperse heat from casing housing inside, countercylinder cavity inner wall carries out forcing cooling, effectively controls cylinder temperature rise.
In order to solve the problems of the technologies described above, the utility model can force inner chamber cooling type tubular diesel pile hammer, comprise lower cylinder, the cylinder body of this lower cylinder is provided with fuel pump and suction and exhaust ports, this fuel pump is connected with atomizer, suction and exhaust ports leads to outer wall of cylinder block from the inboard wall of cylinder block of lower cylinder, the cylinder body outer peripheral face of described lower cylinder is provided with the air inlet communicated with inner chamber, this air inlet one end and cylinder inner wall through, the other end communicates with gas pressure source with pressure, pressed gas is forced to be blown into cylinder chamber by the above-mentioned air inlet communicated with inwall by gas pressure source, inner chamber heat is discharged from lower cylinder suction pore by pressed gas.The quantity of the air inlet that above-mentioned and lower cylinder block inwall communicates at least one.
In said structure, owing to being blown into pressed gas directly to inner chamber outside lower cylinder, not only take away rapidly inner chamber heat, improve heat exchange efficiency, add the cooling capacity of lower cylinder, and blown away the residual gas of inner chamber, improve air change rate and the diesel combustion quality of fresh air, add explosive force and piling efficiency.In addition, according to pile hammer and the length of cylinder block working time, heat number and the height of environment temperature, by controlling to be blown into the pressure of gas, to open the quantity of air inlet, to control and stablize the temperature rise of time cylinder and pile hammer thereof.
Owing to adopting the technical solution of the utility model, its cooling effect by the impact of pile hammer ambient temperature, does not make pile hammer can work continuously for a long time in various construction environment.Distributing in time rapidly of cylinder block heat, not only ensure that normal ignition and the steady operation of pile hammer, and reduces the fault rate of pile hammer, extend application life.
