Abstract
The utility model belongs to GK, the improvement of DF series diesel locomotive diesel engine rocking arm axle bed assembly hoist structure, GK1C type diesel locomotive diesel engine rocking arm axle bed assembly hoist especially, the both ends of cylinder hanging beam are setting up flat arm respectively, the hanger bolt is being installed in the cooperation in the screw that sets up respectively on two flat arms, set up the axial screw on the lower terminal surface of hanger bolt, set up on axial screw and the rocking arm axle bed up end to hang the screw corresponding, it hangs the ear to set up at the center of cylinder hanging beam, be located setting up respectively on the cylinder hanging beam of hanging the ear both sides with rocking arm matched with rocking arm supporting shoe. The utility model is simple and reasonable in structure, convenient to use can make the assembly of rocking arm axle bed keep the level at the hoist and mount in -process, can reduce intensity of labour, improves maintenance efficiency, improves the security.
Description
Technical field
The utility model belongs to the improvement of GK, DF series internal combustion locomotive diesel engine rocker shaft brackets assembling hanger structure, particularly a kind of GK1C type locomotive diesel engine rocker shaft brackets assembling suspender.
Background technology
GK1c type locomotive Valve Gear of Diesel is made up of cylinder head, valve system, valve actuating mechanism three parts.Rocker shaft bed assembling in valve actuating mechanism is Diesel Engine Valve Control Mechanism important component part, and in good time its function coordinates camshaft to open valve, completes air inlet and the exhaust of diesel engine.GK1c type locomotive diesel engine rocker shaft brackets assembling net weight is 45.6 kilograms, and it mainly contains the parts compositions such as rocker shaft bed, the assembling of intake and exhaust rocking arm, spacer and fixing screw.
In upkeep operation in the past, when changing the assembling of GK1c type locomotive air-valve swinging arm of diesel engine axle bed, rocker shaft bed does not have design specialized hanger, the assembling of lifting rocker shaft bed can only be realized by the spacer of lifting rope through rocker shaft bed assembling.Rocker shaft bed assembling integral structure is asymmetric relative to geometric centre, causes rocker shaft bed inclined.In installation process, in order to make rocker shaft bed can accurately be positioned to dowel bolt on cylinder head, need service personnel to exert oneself righting, this adds maintenance intensity virtually.Meanwhile, also need another one service personnel to buttress rocking arm, make rocking arm also maintenance level.Coordinated by two people, rocking arm can be coordinated with camshaft push rod and put in place, as coordinated the not tacit camshaft push rod that very likely causes to be out of shape, affecting repair schedule, increasing recondition expense.Therefore, GK1c type locomotive diesel engine rocker shaft brackets assembling suspender, solves the relevant issues existed in diesel engine of locomotive rocker shaft bed assembling hoisting process.
Utility model content
The purpose of this utility model is to provide a kind of GK1C type locomotive diesel engine rocker shaft brackets to assemble suspender, and it is simple and reasonable for structure, easy to use, rocker shaft bed can be made to be assemblied in maintenance level in hoisting process, can labour intensity be reduced, improve overhaul efficiency, improve safety.
The purpose of this utility model is achieved in that a kind of GK1C type locomotive diesel engine rocker shaft brackets assembling suspender, the two ends of cylinder hanging beam arrange flat arm respectively, coordinate in the screw that two flat arms are arranged respectively and hanger bolt is installed, the lower surface of hanger bolt arranges axial screw, axial screw is corresponding with the hanging screw that rocker shaft bed upper surface is arranged, at the center of cylinder hanging beam, hanging ear is set, be positioned at hanging ear both sides cylinder hanging beam on the rocking arm supporting block matched with rocking arm is set respectively.
The utility model makes rocker shaft bed be assemblied in maintenance level in hoisting process, and to only needing during cylinder head, a service personnel is auxiliary a little just can be located rocker shaft bed erection fast, reduces labour intensity, improves overhaul efficiency.Meanwhile, another people only need buttress the accurate fit that two push rods just can complete rocking arm and push rod fast, reduces owing to coordinating the not tacit and probability that causes push rod to be out of shape.
The utility model using method compared with lifting rope is in the past easy to grasp, easy to use, reduces labour intensity.Meanwhile, its reliable and stable performance, the lifting operation safety that rocker shaft bed is assembled improves greatly, improves overhaul efficiency further.
The utility model is mainly used in the lifting operation of GK, DF series internal combustion locomotive diesel engine rocker shaft brackets assembling.
The utility model is simple and reasonable for structure, easy to use, makes rocker shaft bed be assemblied in maintenance level in hoisting process, reduces labour intensity, improve overhaul efficiency, improve safety.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described, Fig. 1 is main TV structure schematic diagram of the present utility model, Fig. 2 is plan structure schematic diagram of the present utility model, and Fig. 3 is left TV structure schematic diagram of the present utility model, and Fig. 4 is the utility model and rocker shaft bed mounting structure schematic diagram.
Detailed description of the invention
A kind of crystallizer protective case of improvement; as shown in Figure 1, Figure 2, Figure 3, Figure 4; the two ends of cylinder hanging beam 1 arrange flat arm 4 respectively; coordinate in the screw that two flat arms 4 are arranged respectively and hanger bolt 5 is installed; the lower surface of hanger bolt 5 arranges axial screw; axial screw is corresponding with the hanging screw that rocker shaft bed 7 upper surface is arranged; at the center of cylinder hanging beam 1, hanging ear 2 is set, be positioned at hanging ear 2 both sides cylinder hanging beam 1 on the rocking arm supporting block 3 matched with rocking arm 6 is set respectively.Hanging ear 2, for being fixed in the rhombus plate on cylinder hanging beam 1, arranges lifting hole(eyelet) in the upper end of rhombus plate.Rocking arm supporting block 3 is for being fixed in the equicrural triangle plate on cylinder hanging beam 1, matches with rocking arm 6 in the bottom surface of equicrural triangle plate.The top of hanger bolt 5 arranges cylindrical cap, and bottom is connected to stud.
