Suspension strut platform for the dismounting of large-scale diesel engine engine crankshaft bush
Technical field
The utility model relates to a kind of operation platform, specifically, relates to a kind of auxiliary construction platform for the dismounting of large-scale diesel engine engine crankshaft bush.
Background technology
Offshore oil platform generating is multi-cylinder high-power diesel engine with imported large-scale diesel engine, this unit was gone into operation from the eighties in last century, never have specific purpose tool and the method for dismounting engine crankshaft bush, and owing to being subject to the restriction of this unit engine crankshaft bush position structure and surrounding space size, common assembly and disassembly methods is difficult to reach dismounting object, therefore cannot apply and open and inspect identical method with traditional engine crankshaft bush and open and inspect, cause this unit never engine crankshaft bush to be carried out to dismounting inspection since going into operation.Along with the increase year by year of unit operation time, safe operation risk increases day by day.Therefore, in order to guarantee unit safety even running and offshore platform safety in production, in the urgent need to design engine crankshaft bush tool specially for attaching and detaching and assembly and disassembly methods.
At present the domestic method of disassembling light duty diesel engine engine crankshaft bush is simpler, generally with torque wrench, directly unscrews FE Tiler connecting bolt under engine crankshaft bush.Yet the method is only suitable in light duty diesel engine, infeasible for high-power diesel engine the method, need to carry out the design of specific purpose tool and the research of assembly and disassembly methods according to the oil pan structure of unit engine crankshaft bush position and surrounding space size.
Utility model content
To be solved in the utility model is the technical problem of existing large-scale diesel engine engine crankshaft bush dismounting difficulty, and a kind of suspension strut platform for the dismounting of large-scale diesel engine engine crankshaft bush is provided.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
A suspension strut platform for large-scale diesel engine engine crankshaft bush dismounting, comprises that two ends are provided with the rectangular frame of link, is welded with platform panel in described rectangular frame, and described platform panel bottom is provided with reinforcement.
A kind of suspension strut platform for the dismounting of large-scale diesel engine engine crankshaft bush, comprise the first rectangular frame work assemblies and the second rectangular frame work assemblies by gemel connection, described the first rectangular frame work assemblies and described the second rectangular frame work assemblies outer end are welded with respectively link, in described the first rectangular frame work assemblies He in described the second rectangular frame work assemblies, be welded with respectively the platform panel that reinforcement is set, described the first rectangular frame work assemblies bottom welding has connecting bottom board, and the end of connecting bottom board can be fixed by connecting bolt and described the second rectangular frame work assemblies.
The beneficial effects of the utility model are:
The utility model is from high-power diesel engine practical structures and bulk and design, can directly be overlapped on the steelframe of engine block inwall, thereby unsettled hang over engine block inner and be positioned at engine crankshaft bush under, to meet the requirement for height of the dismantling devices such as jack, safe and reliable, easy operating, practical, easier dismounting high-power diesel engine crank axle watt, and effectively prevent that aid is fallen into oil sump in the disassembly process of engine crankshaft bush, can greatly improve engine crankshaft bush dismounting efficiency.
In addition, folding suspension strut platform is convenient to put into engine block inside by manhole more, then in engine block by its expansion locked with connecting bolt, after dismounting completes, unclamp connecting bolt and can directly take out, convenient to use.

The specific embodiment
For further understanding content of the present utility model, feature and effect, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Embodiment 1
As depicted in figs. 1 and 2, the present embodiment discloses a kind of suspension strut platform of bridging type, comprises the rectangular frame 1 being welded by angle steel, and rectangular frame 1 two ends are provided with the link 2 being welded by angle steel.The cross section of link 2 is square, can directly be overlapped on the steelframe of engine block 10 inwalls, thereby make suspension strut platform unsettled hang over engine block inner and be positioned at engine crankshaft bush under, to meet the requirement for height of the dismantling devices such as jack.
In rectangular frame 1, be welded with steel plate as platform panel 3, platform panel 3 bottoms are provided with the reinforcement 4 with rectangular frame 1 welding, thereby make suspension strut platform meet the requirement of strength of its load-bearing.
Embodiment 2
As shown in Figure 3 and Figure 4, the present embodiment discloses a kind of folding suspension strut platform, comprises the first rectangular frame work assemblies 5 and the second rectangular frame work assemblies 6 that by hinge 7, connect.The first rectangular frame work assemblies 5 and the second rectangular frame work assemblies 6 are welded by angle steel, and the first rectangular frame work assemblies 5 and the second rectangular frame work assemblies 6 outer ends are welded with respectively a link 8.In the first rectangular frame work assemblies 5 and the second rectangular frame work assemblies 6, be welded with respectively steel plate as platform panel 3, platform panel 3 bottoms are provided with reinforcement 4.Wherein, the structure of corresponding component and act on identically in the suspension strut platform of link 2, platform panel 3, reinforcement 4 and embodiment 1 bridging type repeats no more herein.
The first rectangular frame work assemblies 5 bottom weldings have connecting bottom board 8, and the end of connecting bottom board 8 can be fixing by connecting bolt 9 and the second rectangular frame work assemblies 6, thereby make the first rectangular frame work assemblies 5 and the second rectangular frame work assemblies 6 be fixed as deployed condition.Folding suspension strut platform is convenient to put into engine block 10 inside by manhole more, then interior by its expansion locked with connecting bolt 9 at engine block 10, unclamps connecting bolt 9 and can directly take out after dismounting completes.
Because the structure of engine crankshaft bush position oil sump is different with bulk, and on engine block 10, the manhole of dismounting engine crankshaft bush is less, while utilizing suspension strut platform of the present utility model to carry out the dismounting of large-scale diesel engine engine crankshaft bush, need two dismounting personnel to coordinate the dismounting engine crankshaft bush of leaning to one side.As shown in Figure 5 and Figure 6, dismounting and installation process be first suspension strut platform to be placed in FE Tiler under engine crankshaft bush under, Bing Jiangqi two ends are connected in engine block 10 inwalls, then unload successively under cross bolts, clamp nut, engine crankshaft bush under FE Tiler, bearing shell tile on tile, bearing shell; After tile maintenance under tile on bearing shell and bearing shell or changing, tile on bearing shell is first installed, then FE Tiler under tile under bearing shell and engine crankshaft bush is installed simultaneously to last clamp nut and cross bolts.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, within these all belong to protection domain of the present utility model.
