Specific embodiment
A kind of specific embodiment of the foldable pedal ladder for multiaxis boxcar of the present invention as shown in Figures 1 to 8, including
Two parallelly distribute ons and three-stage arch vertical pole 1 with railway carriage form fit, allow cross between two vertical poles 1 by being spaced apart
Bar 2 is fixedly connected, and is respectively provided with overturning pedal 3 between adjacent cross bar 2, allow overturning pedal 3 lower end and vertical pole 1 or cross bar
2 is hinged.It is respectively mounted idler wheel 4 on the outside of the upper end of two vertical poles 1, hinged turning rod 5 and makes to overturn in the lower end of two vertical poles 1
Bar 5 is in corresponding 1 inside of vertical pole, allows two turning rods 5 to be arranged in parallel and the connecting rod 51 by being spaced apart is fixedly connected,
And in the fixed overturning locating part 52 in the outside of two turning rods 5.It allows between turning rod 5 and nearest overturning pedal 3 and phase
It is hinged by linkage pull rod 6 between adjacent overturning pedal 3.When pedal ladder folds, turning rod 5 is allowed to overturn to folding direction,
And overturning pedal 3 is made finally to be turned to the state flushed with vertical pole 1；When pedal ladder expansion, turning rod 5 is allowed to turn over to expansion direction
Turn, and when overturning locating part 52 is against the lower end of vertical pole 1, overturning pedal 3 is made finally to be turned to horizontality.
Be arranged through the above structure just constitute it is a kind of of simple structure and low cost, easy to use for multiaxis boxcar
Foldable pedal ladder.In practical applications, by the way that pedal ladder installation position is arranged in the railway carriage side upper half of multiaxis boxcar, and
Guide rail is set in pedal ladder installation position two sides, retaining mechanism is set in pedal ladder installation position bottom outside, allows two 1 upper ends of vertical pole
Idler wheel 4 correspondence be placed in two guide rails.When not using pedal ladder, turning rod 5 is allowed to overturn to folding direction, and steps on overturning
Plate 3 is finally turned to the state flushed with vertical pole 1, and the idler wheel 4 of two 1 upper ends of vertical pole is allowed to be slid onto the upper end of corresponding rails, and
It is locked pedal ladder by retaining mechanism, pedal ladder and the railway carriage of multiaxis boxcar can be made to be fused into one.When need using
When pedal ladder, pedal ladder is unclamped by retaining mechanism, allows the idler wheel 4 of two 1 upper ends of vertical pole to be slid onto the lower end of corresponding rails, allows
Turning rod 5 is overturn to expansion direction, and when overturning locating part 52 is against the lower end of vertical pole 1, overturns overturning pedal 3 finally
To horizontality.It, can be by pedal ladder at this point, pedal ladder, ground and vehicle body are formed firm triangular support configurations
Row repairs to pedal.In pedal ladder during folding and unfolding, due between turning rod 5 and nearest overturning pedal 3 and phase
It is hinged by linkage pull rod 6 between adjacent overturning pedal 3, it need to only overturn turning rod 5 or in which an overturning pedal 3
Make the overturning synchronous with the realization of all rollovers pedal 3 of turning rod 5, has the advantages that easy to operate, work efficiency is high, and pass through linkage
Pull rod 6 can make to form stable support construction between all rollovers pedal 3 and between turning rod 5 and overturning pedal 3, have knot
Simple, the practical feature of structure.
As prioritization scheme, present embodiment has opened up the first through hole 11 in the lower end of two vertical poles 1, two
Turning rod 5 is corresponding to be provided with locating piece 53 with the hinged one end of vertical pole 1, and the second through hole has been opened up on locating piece 53
54.When pedal ladder folds, during turning rod 5 is overturn to folding direction, when overturning pedal 3 is turned to vertical pole 1 together
When flat state, it is overlapped the second through hole 54 and the axis of the first through hole 11.This structure setting second by passing through
Even if being inserted into pin shaft turning rod 5 in hole 54 and the first through hole 11 and vertical pole 1 being fixed, and overturning pedal 3 is made by linkage pull rod 6
The state flushed with vertical pole 1 is kept, has the advantages that structure is simple and convenient to operate, improves pedal ladder in the knot of folded state
Structure stability is conducive to pedal ladder and is organically merged with the railway carriage of multiaxis boxcar.For improve pedal ladder unfolded state when
Support strength, present embodiment are provided with limited block 12 in the downside of overturning pedal 3 and 2 articulated position of vertical pole 1 or cross bar,
And it is fixedly connected with limited block 12 with vertical pole 1 or cross bar 2.When pedal ladder expansion, limited at overturning pedal 3 by limited block 12
In horizontality, the comfort trampled is improved, and the bearing load of linkage pull rod 6 and turning rod 5 can be shared, enhanced to pedal
The structural soundness of terraced unfolded state.
As the scheme that advanced optimizes, present embodiment allows retaining mechanism to include two bolt being symmetric dresses
8 are set, bolt device 8 is allowed to specifically include mounting base 81 and pin shaft 82, pin shaft hole 83, and and pin shaft hole are opened up in mounting base 81
83 sliding slots 84 communicated and limit gap 85.Pin shaft 82 is allowed to pass through from the pin shaft hole 83 of mounting base 81, and solid on pin shaft 82
Surely the limited post of sliding slot 84 is stretched out, and tabletting 86 is set on limited post.Without using pedal ladder and when making its folding, overturning allowed
Bar 5 is overturn to folding direction, and when the second through hole 54 is overlapped with the axis of the first through hole 11, allows two 1 upper ends of vertical pole
Idler wheel 4 be slid onto the upper ends of corresponding rails 7, allow the pin shaft 82 of two bolt devices 8 to move through corresponding to two sides
Two through holes 54 and the first through hole 11, and it is fastened on the limited post on pin shaft 82 in the limit gap 85 in mounting base 81.
When using pedal ladder and when making its expansion, allowing the pin shaft 82 of two bolt devices 8 logical from corresponding second through hole 54 and first
It is drawn back in via hole 11, the idler wheel 4 of two 1 upper ends of vertical pole is allowed to be slid onto the lower end of corresponding rails 7, allow turning rod 5 to expansion direction
Overturning, and when overturning locating part 52 is against the lower end of vertical pole 1, allow the lower end of turning rod 5 to support on the ground, and make to overturn
Pedal 3 is finally turned to horizontality.The retaining mechanism of this structure is simple with structure, it is easy, excellent easily to operate to realize
Point, and can realize while the purpose of be locked vertical pole 1, turning rod 5 and overturning pedal 3.
Further, the vibration to avoid pedal ladder from generating by driving passes through pin shaft 82 from the second through hole 54 and first
It is voluntarily skidded off in hole 11, present embodiment also allows retaining mechanism to be provided with the blade inserting between two bolt devices 8
Lock body 9.And between two vertical poles 1 of pedal ladder and in its lower end position be provided with flip lid 13, allow flip lid 13 upper end
Hinged, the inserted sheet 14 that setting cooperates with blade inserting lock body 9 on the lower end inside face of flip lid 13 with vertical pole 1 or cross bar 2.Work as flip lid
13 when closing, and allows inserted sheet 14 and blade inserting lock body 9 to cooperate and locks, and is pressed in flip lid 13 in tabletting 86.By the way that blade inserting is arranged
Lock body 9, flip lid 13 and its inserted sheet 14 further improve the connective stability of retaining mechanism and pedal ladder, and operation can be improved and pedal
The convenience of vehicle ladder.
Above embodiments are only the descriptions carried out to the preferred embodiment of the present invention, and model not is claimed to the present invention
It encloses and is defined, without departing from the spirit of the design of the present invention, the technology of this field engineers and technicians according to the present invention
The various forms of deformations that scheme is made, should fall within the scope of protection determined by the claims of the present invention.
