Description
Technical field
The utility model relates to the piling machinery technical field of building operations, relates in particular to diesel pile hammer, specifically the improvement of diesel pile hammer cylinder hammer structure.
Background technology
In the piling machinery of building operations, diesel pile hammer is with its simple structure, impact energy is big, operating maintenance is convenient and cold-start performance is good characteristics, is widely used in that bridge, burrock are built, built the road, in the pile foundation engineering constructions such as hydraulic engineering and industry, civilian construction.
Present diesel pile hammer, especially guide rod type diesel pile hammer mainly comprise the piston that is fixed on lower end of the guide rod, impact part the cylinder hammer, be connected in the parts such as crossbeam, the undercarriage on the crossbeam and guide rod of guide rod upper end, its operating principle is similar to two stroke diesel engine.During diesel pile hammer work, the hammer hook of diesel pile hammer undercarriage unclamps, the free-falling of cylinder hammer, when cylinder hammer drops to when entangling piston position, piston and on piston ring just with the cylinder chamber sealing of cylinder hammer, at this moment the air between piston and cylinder just is compressed, its pressure and temperature is raise fast, when being compressed to a certain degree, diesel oil is the atomizing shape through oil nozzle and sprays in the combustion chamber, the blast of spontaneous combustion immediately after atomized fuel sprays into, the explosive force that blast produces reaches in the stake by piston, pile cover, pile cover seat, and stake is sunk; This explosive force also acts on the cylinder hammer simultaneously, the cylinder hammer is upwards takeoff, to prepare to enter next working cycles along guide rod.
So the cylinder hammer of diesel pile hammer is the vitals that impacts piling, height, the size of impact energy and the length in application life of its piling efficient depend on cylinder hammer chamber and structure of piston pattern and working clearance thereof to a great extent.The cylinder hammer of existing diesel pile hammer all is to be provided with the cylindrical cylinder chamber on cylinder body, because the compression ratio of diesel hammer is higher, gaseous-pressure is big, temperature is high, the working environment of cylinder hammer and piston is very abominable, and cylinder hammer chamber be inserted in piston to be inserted in length long more, the pressure in its cylinder chamber will be high more, this gases at high pressure are scurried into the piston ring back side just must form back pressure, greatly increasing the pressure of piston ring, the cylinder friction damage is sharply increased cylinder chamber wall.Thereby cylinder chamber ubiquity on longitudinal section of existing cylinder hammer up big and down small " back taper " wearing and tearing, present the trend of accelerating damage thereupon, this not only makes the blast impulse power of diesel hammer reduce greatly, cause wiping cylinder, snap ring,, pound ring, causing can't operate as normal, and this also will cause excessive impact wear, shorten the application life of pile hammer greatly.Again owing to the discharge of pile hammer cylinder chamber waste gas is finished in cylinder hammer spring process, and cylinder cylinder chamber and the back taper cylinder chamber that forms subsequently, very be unfavorable for the filling of cylinder chamber exhaust gas discharging and fresh air, this must cause incomplete combustion again, very easily produce carbon distribution, accelerated wear test causes the wearing and tearing of top, cylinder chamber even more serious than regular wearing and tearing.
The utility model content
The technical problems to be solved in the utility model provides a kind of awl chamber cylinder hammer of diesel pile hammer, and it can not only prolong the application life of cylinder hammer effectively, and exhaust performance is good, high efficiency.
In order to solve the problems of the technologies described above, the awl chamber cylinder hammer of diesel pile hammer of the present utility model comprises cylinder body and cylinder chamber, and this cylinder chamber is arranged on the cylinder body, and described cylinder chamber is circular cone structure, and this frustum of a cone upper base circular diameter is less than the circular diameter of going to the bottom.
After adopting said structure, because cylinder chamber presents the normal cone platform structure of upper base circular diameter less than the circular diameter of going to the bottom.This on the one hand " positive frustum " cylinder chamber not only can compensate the back taper wear extent of cylinder chamber and piston ring, thereby prolong the application life of cylinder hammer greatly, and the seal in this awl chamber again just at the right time with cylinder chamber in gas pressure proportional, be particularly conducive to the confined explosion of diesel hammer cylinder chamber and fully burning.The positive frustum structure of this cylinder chamber on the other hand, constituted a kind of wide-mouth cavity configuration that Open Side Down, can impel the smooth discharging and the filling of fresh air in conical cavity of cylinder chamber internal combustion waste gas effectively, it is good not only to have exhaust performance, complete, the sufficient advantage of fuel combustion, and avoided carbon distribution in the chamber effectively, thus reduce wear, avoid the generation of wiping cylinder, snap ring, pounding phenomenons such as ring.This structure also has simple in structure, processing, characteristics easy to maintenance.
Further embodiment of the present utility model is, between cone angle alpha=0 in the truncated cone chamber of described cylinder chamber °～5 °.Strengthen its exhaust performance this application life that had both helped improving the cylinder hammer, can keep its seal admirably in the radial elastic scope of piston ring again, and operating efficiency is higher.
