Abstract
The utility model discloses a wholly-dismountable power unit group on a diesel engine. The wholly-dismountable power unit group on the diesel engine comprises an air cylinder cover, an air cylinder sleeve, a piston and a connecting rod and is characterized by further comprising a power group stopping block, the top of the air cylinder sleeve is connected with the air cylinder cover through a bolt, the bottom of the air cylinder sleeve corresponds to the piston and the connecting rod and is in bolt connection with the power group stopping block, and the power group stopping block is provided with a screw for limiting the freedom degree of the connecting rod and a fine adjustment screw for adjusting the vertical position of the piston. The wholly-dismountable power unit group is simple in structure, reasonable in design, capable of simultaneously achieving whole dismounting and independent dismounting of the air cylinder cover, the air cylinder sleeve, the piston and the connecting rod. The power group stopping block can be conveniently dismounted. When the large end of the connecting rod is installed on a crankshaft, the connecting rod has fault-tolerant and fine adjustment functions. The wholly-dismountable power unit group achieves modular diesel engine assembly and is widely applicable to 2000KW-3500KW diesel engines for railway locomotives and ships.
Description
Technical field
The utility model belongs to Diesel Engine Technique Field, particularly relates to the power unit group on a kind of diesel engine.
Background technique
At present, when domestic 2000KW～3500KW high-power diesel engine maintaining, cylinder head, cylinder liner, piston, connecting rod are all unit independently, in the time of installation and removal motor, cylinder head, cylinder liner, piston and connecting rod be dismounting on diesel engine separately all, thereby has caused the inconvenience of dismounting, maintenance, maintenance and transport.How to solve this technical problem and become the direction that these those skilled in the art make great efforts.
Model utility content
The purpose of this utility model is just to provide on a kind of diesel engine power unit group that can integral disassembly, assembly, has solved the problem that above-mentioned prior art exists.
The purpose of this utility model realizes by following technical proposals:
Power unit group that can integral disassembly, assembly on a kind of diesel engine, comprise cylinder head, cylinder liner, piston and connecting rod, it is characterized in that: also comprise power packages block, cylinder liner top is connected with cylinder head by bolt, the corresponding piston in cylinder liner bottom and connecting rod bolt power packages block, the screw of restricted connecting rod degrees of freedom and for adjusting the micrometer adjusting screw of piston upper-lower position on this power packages block.
As preferably, in described cylinder liner, there is water ring, excessively on water ring end face, offering bolt hole, adopt stay bolt to run through with bolt hole and coordinate from cylinder head top, cylinder head and cylinder liner are assembled together.
As preferably, described power packages block comprises substrate and is located at the riser on substrate, and substrate is bolted on cylinder liner bottom end face, and which is provided with the micrometer adjusting screw corresponding with piston, and on riser, respective link is provided with lock screw and adjusting screw.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, reasonable in design, can realize the integral disassembly, assembly of cylinder head, cylinder liner, piston and connecting rod and the independent dismounting to these parts simultaneously; Power packages block can easy disassembly; To on bent axle time, there is fault-tolerant and fine adjustment function at installing connecting rods major part; It has realized diesel engine modular assembly, and it is applicable to the diesel engine of railway locomotive, 2000KW～3500KW power peculiar to vessel widely.

Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As shown in Figures 1 to 5, power unit group that can integral disassembly, assembly on a kind of diesel engine, comprise cylinder head 4, cylinder liner 3, piston 2, connecting rod 1 and power packages block 5, cylinder liner 3 tops are connected with cylinder head 4 by bolt, the cylinder liner 3 corresponding piston 2 in bottoms and connecting rod 1 bolt power packages blocks 5, the screw of restricted connecting rod 1 degrees of freedom and for adjusting the micrometer adjusting screw of piston 2 upper-lower positions on this power packages block 5.
Referring to Fig. 5, in described cylinder liner 3, there is water ring 10, excessively offering 4 bolts hole on water ring 10 end faces, adopt 4 interior hexagonal stay bolts 11 to run through with bolt hole and coordinate from cylinder head 4 tops, cylinder head 4 and cylinder liner 3 are assembled together.
Referring to Fig. 2, described power packages block 5 comprises substrate 51 and is located at the riser 52 on substrate 51, substrate 51 is fixed on cylinder liner 3 bottom end faces by 4 bolts 6, and which is provided with the micrometer adjusting screw corresponding with piston 27, and on riser 52, respective link 1 is provided with lock screw 8 and adjusting screw 9.
Referring to Fig. 3, described cylinder liner 3 bottom end faces evenly offer 12 bolts hole 31, thereby facilitate the installation of power packages block 5.
In use, substrate 51 effects of power packages block 5 are seized piston 2 bottoms, prevent its whereabouts.Lock screw 8 on riser 52 is for limiting the degrees of freedom of this power unit assembling timing connecting rod 1, collide the miscellaneous part of diesel engine to time on body to avoid assembling power unit group, after power unit group is installed on diesel engine, need installing connecting rods major part on bent axle time, adjusting screw 9 coordinates adjusting with lock screw 8, connecting rod 1 can be swung, be convenient to assembling.Micrometer adjusting screw 7 is for adjusting among a small circle the upper-lower position of piston 2, thereby is convenient to being connected between installation or removal connnecting rod big end and bent axle.After the major part of power unit group connecting rod and bent axle assemble, need to take off power packages block 5; Otherwise, in the time of dismounting power unit group, also need first to install power packages block 5.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
