Technical field: the present invention relates to a kind of load bearing arm electrical generator transport trolley constructional device.

Background technology: accelerate electric power structural adjustment, develop actively nuclear power, with project be rely on carry out absorbing simultaneously, digest, the synchronized development that domesticizes is China 2005-2020 energy mix developing policy, nuclear power reactor does not have overheater, saturated steam can only be produced, so nuclear steam turbine steam condition is low, flow area is large, low pressure cylinder length of blade is greater than overcritical and extra-supercritical unit, by the restriction of blade material intensity, the nuclear steam turbine of million kilowatt can only be Half Speed and 1500r/min, the nuclear power generator determining million kilowatt is also necessary for Half Speed, i.e. level Four electrical generator, the limit of current domestic application generator unit stator railway transportation is the full speed electrical generator of 1,000,000 kilowatts, and level Four electrical generator is due to heavier, contour dimension is larger, can only water-borne transport, so stator transport becomes one of restraining factors of inland Construction of Nuclear Electricity, for reducing every kilowatt of investment, nuclear power generating sets single-machine capacity constantly increases, and three circuit volumes reach 110-120 ten thousand kilowatts, four loop 150-170 ten thousand kilowatts, transportation problem becomes key issue, even if adopt water-borne transport, the transport also not a duck soup of 1,000,000 current stators, must pay a high price, and heavier stator will be all severe problem to all transit links,

Country's nuclear power will adhere to that set objective is building up inland nuclear station as the real mark absorbing, digest three generations's nuclear power technology, and this bottleneck problem of design solution determinant overland transportation of nuclear power generator is the problem that exploitation Large Copacity modern nuclear power generator must solve:

Due to nuclear power generator stator faces size and weight more in the past generator unit stator more greatly, heavier, conventional art can only adopt sea-freight, transportation problem becomes the restraining factors of the construction of nuclear power station, depressed centre flat wagon transportation mode in the past, schnabel car transportation mode all cannot meet the transportation request of nuclear power generator stator;

Technical scheme as existing patent " generator stator self-bearing conveyer " ZL200810209716.7 is " concentrate carrying Tiebar structure, draw money on credit arm flange and generator unit stator of one-way bearing spigot structure and two assembles and forms agent structure, this agent structure is docked with vehicle to run portion and is formed vehicle, two arm flanges of drawing money on credit adopt one-way bearing spigot structure to dock with the two ends of generator unit stator, with bolt handle and, prestress concentrates carrying Tiebar structure to run through two arm flange lower ends of drawing money on credit, the arm end of arm flange of drawing money on credit is provided with first auxiliary structure of cartridge of vehicle, first auxiliary structure of side bearing, first auxiliary structure of interior guiding, form the mating interface of second auxiliary structure corresponding to vehicle to run portion, the self-supporting structures that this self-bearing conveyer of generator unit stator is formed directly docks with the part-structure of vehicle and running part and forms complete vehicle, possesses the performance that travelled by vehicle is necessary ", but nuclear power generator uses such scheme to there is following point: be first that nuclear power generator diameter is larger, the diameter of arm flange of drawing money on credit also must corresponding increase, make weight exceed restriction, prestress concentrates carrying Tiebar structure to occupy height space size, makes overall height dimension exceed gauge size, nuclear power generator is also heavier, and prior art cannot be implemented.

Summary of the invention: the object of this invention is to provide a kind of load bearing arm electrical generator transport trolley constructional device, the feature also larger according to larger, the unshakable in one's determination intracavity diameter of nuclear power generator stator diameter, utilize inner chamber unshakable in one's determination accommodation stiffness can both meet the load bearing arm of load bearing requirements, and be medium by carrying saddle, support generator unit stator two ends end face, bear stator weight; Avoid the weight adopting conventional art to bring to increase and gauge size increase problem, alleviate dead weight of vehicle, realize the railway transportation of heavier larger nuclear power generator stator.

Technical scheme of the present invention is: a kind of load bearing arm electrical generator transport trolley constructional device, is characterized in that: load bearing arm is through the inner chamber unshakable in one's determination of generator unit stator, and load bearing arm supports generator unit stator end face by saddle; Second secondary and second pair of side bearing of first secondary cartridge with two groups of bogie truck groups of first secondary and side bearing of load bearing arm two ends cartridge coordinates; Load bearing arm two ends guide finger coordinates with the pilot hole of two groups of bogie truck groups; Load bearing arm is I-beam section structure, and two end sections are middle part necking in comparatively.

Technique effect: the feature that larger, the unshakable in one's determination intracavity diameter of the present invention's foundation nuclear power generator stator diameter is also larger, utilize inner chamber unshakable in one's determination accommodation stiffness can both meet the load bearing arm of load bearing requirements, and be medium by carrying saddle, support generator unit stator two ends end face, bear stator weight; Avoid the weight adopting conventional art to bring to increase and gauge size increase problem, alleviate dead weight of vehicle, realize the railway transportation of heavier larger nuclear power generator stator; Because there is first secondary, first secondary and guide finger of side bearing of cartridge at load bearing arm two ends, modular design advantage can be played, the bogie truck group of existing vehicle is used to form new vehicle, reduce the manufacturing cost of new car, the important breakthrough of vehicle performance is given by the innovation of primary load bearing structure bearing mode, railway transportation implemented by the nuclear power generator that cross dimensions and weight grade are exceeded in the past, eliminates traffic limitation bottleneck.
