Abstract
The utility model discloses a drum type diesel pile hammer fuel supply device which uses two or more groups of independent fuel pump system. The fuel supplying device is a double-acting fuel pump device. When the upper piston is free dropped after lifted up, the piston impacts oil pressure levers of each fuel pump device in the same height, promotes a piston and opens a oil delivery valve, transports high pressure fuel to a nozzle through oil pipe, injects fuel to a combustion chamber, thus realizes a piling operation of the diesel pile hammer. The utility model can reduce a force condition of a piston couple in the fuel pump mechanism, effectively avoid a damage of oil pressure levers and other components, ensure normal operation of the diesel pile hammer and extend a service life of the diesel pile hammer. In addition, due to a reduced force of the piston couple, constructors can change the fuel pump oil quantity and do exhausting operation to fuel supply system easily and flexibly, thus the safety is guaranteed when operation is performed offshore.
Description
Technical field
The utility model relates to a kind of fuel supply device of tubular diesel pile hammer.
Background technology
At present, the fuel oil system of tubular diesel pile hammer mainly is made up of fuel tank, cylinder, upper piston, fuel pump, atomizer and fuel pipe, by mentioning upper piston and freely falling, bump fuel pump laminated oil lever, make fuel pump that a certain amount of diesel oil is sprayed fuel oil by atomizer to the combustion chamber of diesel hammer, the diesel oil atomization after-explosion produces explosive force stake is laid.The fuel pump of diesel hammer configuration at present is the single-acting form, promptly finishes the fuel feeding action by one or two atomizers of a fuel pump delivery valve connection.And the fuel pump of diesel hammer adopts manual variable to regulate fuel delivery, by the interlinked mechanism of fuel pump cam ring and laminated oil lever, makes fuel pump inner plunger stroke adjusted, realizes the change of fuel pump fuel delivery size subsequently.Raising along with the diesel oil blow energy, require the each fuel delivery of fuel pump to do corresponding increase, adopt the way that strengthens the secondary diameter of fuel pump plunger at present, can make the stressed increase of plunger pair, cause the damage of parts such as laminated oil lever easily, directly influence the operate as normal of diesel hammer, and shorten the application life of diesel hammer.In addition because the stressed increase of plunger pair, give constructor's conversion fuel pump oil mass and when fuel oil system carried out bleeding and brings great inconvenience, particularly diesel hammer operation at sea safety can not ensure.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of fuel supply device of tubular diesel pile hammer, can reduce the force-bearing situation of plunger pair in the fuel pump mechanism, effectively avoid the damage of parts such as laminated oil lever, ensure the operate as normal of diesel hammer, prolong the application life of diesel hammer.
For solving the problems of the technologies described above, the technical scheme of a kind of tubular diesel pile hammer fuel supply device of the utility model is, comprise casing top half, fuel tank, upper piston, oil inlet pipe, following cylinder, oil pipe and atomizer, wherein, also comprise the double acting fuel pump of forming by many groups of separate fuel pumps; Described double acting fuel pump is installed in down on the cylinder, is connected with fuel tank by oil pipe; Every group of fuel pump device is provided with laminated oil lever, plunger and delivery valve, and described delivery valve is connected with atomizer; When freely falling after upper piston is raised, can clash into the described laminated oil lever that is in corresponding height, laminated oil lever promotes plunger and opens delivery valve synchronously, by oil pipe high pressure fuel is transported in the described atomizer, to the combustion chamber oil spout between upper piston and lower piston.
The utility model satisfies the fuel delivery of the needed large impact energy of diesel pile hammer by the double acting fuel pump device, need not increase plunger pair diameter in the fuel pump mechanism, make the stressed of part such as laminated oil lever improve, guarantee the normal use of diesel hammer, prolong its application life.Make operating personnel's energy easy and flexible ground conversion fuel pump oil mass simultaneously and fuel oil supply system is carried out bleeding, the safety when making operation on the sea is protected.

The specific embodiment
As depicted in figs. 1 and 2, the utility model comprises casing top half A, fuel tank 1, upper piston 2, oil inlet pipe 3, following cylinder B, oil pipe and atomizer 5, wherein, also comprises the double acting fuel pump C that is made up of some groups of separate fuel pumps; Described double acting fuel pump C is installed in down on the cylinder B, is connected with fuel tank 1 by oil pipe; Every group of fuel pump device is provided with laminated oil lever C1, plunger C2 and delivery valve C3, and described delivery valve C3 is connected with atomizer 5; When freely falling after upper piston 2 is raised, can clash into the described laminated oil lever C1 that is in corresponding height, laminated oil lever C1 promotes plunger C2 and opens delivery valve C3 synchronously, by oil pipe high pressure fuel is transported in described some atomizers 5, to the combustion chamber oil spout between upper piston 2 and lower piston 6, thus the piling work of realization diesel hammer.
Described oil pipe can be a high-pressure oil pipe 4, also can be the multichannel oil pipe that the Y-type three way type joint connects.
As shown in Figure 2, double acting fuel pump C is fixed on down on the mounting plane of cylinder B by connecting bolt, and guarantees to guarantee its synchronous fuel feeding on the sustained height plane of following cylinder B.Fuel pump delivery valve C3 is connected with each atomizer 5 by high-pressure oil pipe 4, on the mounting plane of the sustained height of each atomizer 5 by being bolted to down cylinder B, guarantees that it is to diesel hammer combustion chamber oil spout uniformity.
As shown in Figures 2 and 3, the fuel feeding of double acting fuel pump C action is to promote plunger C2 owing to bump that laminated oil lever C1 is subjected to piston, and the pressure fuel oil of generation is opened delivery valve C3, is transported to atomizer 5 by high-pressure oil pipe 4.
As shown in Figure 3 and Figure 4, the fuel pump fuel delivery is regulated and fuel oil system bleeding and the adjusting of fuel feed amount size, then driven by spurring control wire C4 that the C6 of cam linkage mechanism carries out.When the control wire C4 on the right of the downward pulling, cam mechanism C6 rotates and jack-up depression bar C1, makes laminated oil lever C1 lower end inwardly advance plunger C2, has increased the fuel delivery increase, otherwise the fuel delivery of fuel pump reduces.Because fuel pump plunger C2 diameter does not strengthen, the required plunger C2 inner spring back pressure that overcomes did not increase when the constructor spurred control wire, made easy and flexible operation.
