Description
Technical field
The present invention relates to the working position apparatus used in a kind of marine low speed diesel engine manufacture process, in particular a kind of for marine low speed diesel engine connecting rod cross head assembly assembling and transhipment apparatus for work and method, belong to machinery manufacturing technology field.
Background technology
In the manufacture process of heavy-duty machinery, often face the problem of the assembling of bulky, that quality is overweight heavy parts, storing and transhipment.Some large parts of marine low speed diesel engine, as connecting rod cross head assembly, see Fig. 1, the slide block 15 comprising connecting rod 14 and be attached thereto, its volume is very huge, some height or even Human Height several times.
The assembling of traditional connecting rod cross head assembly, storing and transporting mode, in Assembling Production place, mark certain region specially in order to build the assembling operation melt pit sinking to ground, and lay track in melt pit, then be equipped with thumbnail bolt etc. and connecting rod cross head assembly installed fixing; Then above operation melt pit, the springboard etc. being used for operator and ascending a height is laid, to meet the action need of connecting rod cross head assembly assembly working.Be limited to size, the limited amount of the connecting rod cross head assembly that can hold in melt pit, a general melt pit can only meet the needs of the connecting rod cross head assembly assembling of two diesel engines.
For most marine diesel manufacturer, the construction of assembling operation melt pit depends on the experience of plant designing personnel, and its general layout is just determined when factory building civil engineering, once workshop building completes, rethinks the technical difficulty of setting up operation melt pit very large.And regenerate along with the continuous renewal of marine low speed diesel engine product, its connecting rod cross head assembly can be updated in size, structure etc., certain difference is there is with old product, thus higher different requirements are proposed to the assembling aspect such as place, machine equipment, therefore only rely on the mode of primary construction melt pit cannot meet the needs of diesel engine diversity development.Current rhythm of production, generally than very fast, after requiring that the connecting rod cross head assembly of a machine assembles, vacates the assembling that operation melt pit carries out the connecting rod cross head assembly of another machine at once.Be limited to the particularity of connecting rod cross head assembly structure, the connecting rod cross head assembly assembled must be placed on one's feet, therefore existing operation melt pit cannot meet the demands, even if the connecting rod cross head assembly assembled is hung and delivers to diesel engine assembly shop, also with handling piece by piece of driving a vehicle, thus can only seriously take the resource of travelling facility and operation melt pit, cause a large amount of personnel, melt pit place is in and treats work state, serious waste man-hour, be provided with huge obstacle to the raising of labor productivity.
In sum, the traditional approach utilizing operation melt pit to carry out the assembling of connecting rod cross head assembly also exists following shortcoming:
1, higher to the requirement of workshop building.Construction technique difficulty and the cost of connecting rod cross head assembly assembling operation melt pit are higher, and the size of melt pit, the degree of depth, quantity must with certain perspective, are difficult to adapt to completely state of development and the market demand in diesel technology future.
2, the difficulty of operation melt pit transformation is large, very flexible.Operation melt pit once build up, for wanting to change its position, size, the degree of depth etc. or shift position all without operability.Diesel engines at present is towards the future development of ultra-long-stroke and new generation of environment protection main frame, and huge change all occurs for the size, length etc. of connecting rod, the transformation of operation melt pit not only the cycle long but also forever do not catch up with the paces of diesel engine development.
3, large to the dependence of transloading equipment, that operation melt pit takies inefficiency is high, utilization rate of equipment and installations and efficiency low.The assembly working of connecting rod cross head assembly requires that connecting rod must be in standing state, also still needs the mode of standing and carry out depositing and transporting after having assembled, and thus when producing nervous, can incur loss through delay manufacturing schedule because waiting for driving handling; In addition, in view of the requirement of shipowner is more and more higher, often there is the situation needing after diesel engine is submitted to disassemble connecting rod cross head assembly and keep in repair, the maintenance general cycle of connecting rod crosshead is longer, once need to take operation melt pit because keeping in repair, then can have influence on the normal assembly working producing connecting rod cross head assembly.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, the traditional approach utilizing operation melt pit to assemble is optimized and is improved, a kind of apparatus for work and method thereof of marine low speed diesel engine connecting rod cross head assembly are provided, have Active workings flexibly, take up an area little, easy to maintenance, the overall transportation by lighter in space simple efficient, save the feature such as operation melt pit and activity duration resource, reach the effect reducing time to wait, reduce the dependence to transloading equipment and the serious ineffective occupation to operation melt pit, improve utilization rate of equipment and installations and efficiency.
