Description
Technical field
The utility model belongs to bogie replacement field, and in particular to a kind of two-way can move without melt pit replacement bogie
Dynamic track bridge mechanism.
Background technique
Bogie plays substantivity as the critical running mechanism of rail truck, to the safety of rail truck operation
Effect, it is therefore necessary to ensure the good operating status of bogie and comprehensive performance.Bogie more exchange device is for completing railway
The important equipment of car inspection and repair, and the efficiency for replacing bogie is higher, is widely used in motor-car in institute, achieves noticeable achievement.
Existing bogie more exchange device is set to as shown in patent document CN201132555Y and individually faces Xiu Kunei,
Referring to Fig. 1, mainly by mounting and dismounting lines, storage line, cross traveling trolley, car body unwheeling device, telescoping bracket device, electric control system etc.
Composition repairs that library stock rail is located at ground and cross traveling trolley and telescoping bracket device occupied space are larger due to facing, need to be into
The special melt pit design of row, the mounting and dismounting lines and storage line of below stock rail and lateral side need to be arranged multiple deep melt pits and shallow
Melt pit, depth respectively reach 2000mm and 1236mm or so；Setting rail 12 is used to support above the stringer of its hoistable platform
Elevating mechanism framework platform is arranged in the outer ring of steering framing wheel pair, stringer platform lower section, and hoistable platform is overall structure, rail 12
Using symmetrical inclined design, it is excessively high that these have resulted in turning to the whole height being placed on hoistable platform, planar dimension also mistake
It is big overweight, high to elevating mechanism requirement, and the stress of hoistable platform is unreasonable, is easy to happen the damage such as fatigue, needs entirety more
Change hoistable platform, service life is short costly, in moving process steering framing wheel to it is easy sliding, it is dangerous, be easy to cause damage.
Bogie more exchange device, which is generally located on, individually faces Xiu Kunei, because facing Xiu Kunei setting particularly is provided with transverse direction
Melt pit more changes jobs dedicated for bogie.
EMU utilization overhaul facility and equipment are the basic guarantees of overhaul of train-set quality, wherein check that library is to carry out
The maintenance of one second level of EMU, the critical facility reorganized and outfit, can carry out EMU inspection, overhaul, unload dirty, flaw detection, department multiplies, reorganizes and outfit etc. one
Body is turned into industry, checks that all station tracks configure track bridge in library.
Track bridge is the basic tooling for implementing EMU I and II inspection maintenance, is that motor-car uses three layers of job platform

With the appearance of new maintenance requirement and the development of maintenance model, need to be turned on checking library internal rail bridge
Frame replacement operation, however the fulcrum spacing of track bridge is less than the required bulk of bogie lifting, and it is again difficult to increase fulcrum spacing
To guarantee the bearing requirements of EMU, in addition, track bridge must not interfere the dismounting of bogie, and cannot break when replacement bogie
The bad structure for checking hole.However the lateral melt pit of common bogie more exchange device destroys the solid concrete roabed of track bridge and checks hole
Structure, while occupied space is big, can produce bigger effect to the Inspection in library is checked.
Although active rail bridge scheme exists in the prior art, all it is simple laterally unidirectional movement, is unsatisfactory for
State requirement.Such as in patent document CN201473834U and CN206298788U, as shown in Fig. 2, active rail bridge transverse shifting,
Steering framing wheel is got out of the way to the dropping channel checked on library transfer orbit trolley is dropped to, check library transfer orbit trolley from front and back
End removes, and vertically moves long-term occupy and checks hole, very disruptive others normal inspection operation；To be moved from intermediate lateral
Out, then lateral melt pit destroys the solid concrete roabed of track bridge and checks hole structure, while occupied space is big, while to laterally adjacent
The Inspection of track bridge brings adverse effect.
