Description
Technical field
The invention belongs to sleeper beam erecting device and its installation method of the car body of aluminum alloy single track train under formal dress state
A kind of field, and in particular to the sleeper beam erecting device and its installation method under gyrocar car body formal dress state.
Background technology
The floor 1-1 of the car body of current aluminum alloy single track train with the sleeper beam 2 of car body is carried out in underframe synthesis procedure
Group weldering, is respectively integrated bottom frame 1 with two edge beam of underframe 1-2 groups welderings first by floor 1-1 as shown in Figure 1 to Figure 3, then will
Integrated bottom frame 1 overturn to anti-dress state as shown in Figure 4 and in the middle part of corresponding vehicle body door two sleeper beams 2 of line positioning position
Put, two sleeper beams 2 are completed into a group weldering with the underframe 1 under anti-dress state, hereafter, the anti-dress underframe 1 with sleeper beam 2 is turned over again
Go to formal dress state, then with compartment 3 groups weld the aluminum alloy single track car car body composition 10 to be formed as shown in Figure 5 and Figure 6.
However, under special operation condition, compartment 3, floor 1-1, the underframe 1 of formal dress state and its side bar are in other operations
Under complete group weldering, thus form the train body for only lacking sleeper beam 2.Due to car load car body now it is huge and heavy,
Jing cannot continue to use old method and be overturn, for this purpose, being accomplished by positioned at the ground of vehicle bottom and underframe 1 in formal dress state
Directly group welds sleeper beam 2 on plate 1-1 and edge beam of underframe 1-2.
But, because the length dimension of car load car body is very big, therefore it can become during integral lifting by gravity
The impact of shape and make floor 1-1 and edge beam of underframe 1-2 produce deflection deformation, so as to change original basic size.This is scratched
Degree deformation can cause group the butt weld position needed for weldering sleeper beam 2 to occur compared with big gap, and be distributed in edge beam of underframe 1-2 and
Multiple positions of floor 1-1, it is difficult to corrected by conventional method adjusting, ultimately resulting in many places weld seam cannot meet welding need
Ask, the group weldering operation of the underframe 1 and sleeper beam 2 that in turn result in required formal dress state cannot be implemented.
The content of the invention
Deflection deformation is produced because of action of gravity in order to solve the existing car load car body under formal dress state, it is caused just
Dress attitude under bottom frame floor cannot be in theory position while welding match with sleeper beam, its weld gap is excessive, and this kind of feelings
Condition is occurred on multiple positions of underframe simultaneously, causes many places weld seam to meet welding demand, and then causes formal dress state
Bottom frame floor and sleeper beam the technical problem that cannot implement of group weldering operation, the present invention provides a kind of gyrocar car body formal dress state
Under sleeper beam erecting device and its installation method.
The technical scheme that present invention solution technical problem is taken is as follows：
