Embodiment
1-4 describes a kind of embodiment of the present utility model below in conjunction with the accompanying drawings.
Flat car machinery pull-type foldable step mechanism, has flat board vehicle carriage 1, in order to be installed to flat car car body with car
It is available for staff to climb up the step mechanism that car body platform is operated at any time, casing is fixedly mounted prior to the sidepiece of vehicle frame 1
2, casing 2 can use square structure simple in construction and relatively conventional, be not limited, mainly played by casing 2 herein
Storage and protection double action to step, furthermore, realize the installation of step mechanism, so, casing 2 indirectly by casing 2
Installation site it is also more wide in range, as long as that is, vehicle frame 1 sidepiece arbitrarily select the installation of position all can, the applicable car of installation institute
The versatility of type is wider.
Further, the casing 2 is used for the folding step 3 for storing from pull at its front opening to go out, and folds
One end of step 3 by rolling friction structure 4 and casing 2 realize can pull relative motion.Under prior art, there are some foldings
Step 3 is to realize to connect by sliding friction structure and casing 2, such as sliding block and slideway, chute and hook.And this programme uses
Purely mechanic rolling friction structure 4 is connected with casing 2, further reduces frictional resistance compared with having for sliding friction structure
Effect, hence in so that fold step 3 out of casing 2 storehouse pull and the operation that goes out is more light and handy nimble.In addition, rubbed using rolling
Wipe structure 4 and fold the structure of step 3, on the one hand fold step 3 and the structure for the step that is connected is welded more directly on car body more
To save vehicle body space, on the other hand, fold associated through pulling motion by rolling friction structure 4 between step 3 and casing 2
Come the mounting structure used, structure is more simplified for relatively deploying folding step mechanism using hydraulic system, and operation is more
It is convenient, under the premise of possessing identical use function, more save financial cost.
In addition, on the basis of above-mentioned technical characteristic, stepped in order to ensure folding step 3 in device stepping on during use
Stability, lower surface, which is additionally provided with, at the front opening of the casing 2 to be stable in vehicle side by the folding step 3 for deploying to use
The limiting bracket 5 in face, make the folding step 3 of expansion that relative displacement not occur by the spacing and supporting role of limiting bracket 5
Or relatively rotate.Moreover, in this programme, casing 2 is because installed in the outside of vehicle frame 1, the folding step 3 in it pulls out casing 2
It could be used after outer, now, the front end of casing 2 turns into the main stress point for folding step 3, and therefore, folding step 3 needs extremely
Firm support just can ensure that ascending stair safety, in order that casing 2 has sufficiently solid intensity to support stepping on for step 3 of folding to step on
Use, the tilting supporting construction 6 for being used to consolidate the installation of casing 2 is additionally provided between the bottom of the casing 2 and vehicle frame 1.It is preferred that
Ground, the supporting construction 6 can be made of a tilting single or more metalwork, can be made as shown in the figure of angle steel, its head and the tail
It is connected respectively with the opening downside of casing 2 and the lower end installation place of vehicle frame 1 and surrounds triangular structure to consolidate the peace of casing 2
Dress.
In above-described embodiment, it is preferable that the casing 2 for inner band guide rail 7 square box (as shown in Figure 1, Figure 2, Fig. 4 institutes
Show), its height with fold step 3 completely fold fold it is rear it is horizontal positioned its it is interior when total height be adapted, its length with fold
Step 3 folds completely to be folded rear horizontal positioned most long end size in it and is adapted.So, it is in order that 2 body structures of casing
It is more compact, while preventing take up larger space, and make it have the function of storage, moreover it is possible to appoint to fold step 3 in it
The realization of meaning pulling motion provides mounting structure and supported.
To make the overall structure of device firm, simple and stably, and the folding functional for folding step 3 is specifically realized,
The folding step 3 is made of quarter bend, it is preferred to use quarter bend, the rectangle plane of quarter bend is more conducive in step mechanism while light and handy
The installation of each parts.In addition, the folding step 3 includes one end and realizes relative motion by rolling friction structure 4 with casing 2
The first step 301, and pass through end to end second step 302 of hinge 9 with the first step 301.When the of two units
After one step 301 and the second step 302 fold, being provided between each foldable unit for folding step 3 can be by each folding
The locking drag hook 303 that unit is connected as a single entity.Specifically, the locking drag hook 303 can be made up of coupler body and latch closure.
In order to realize that the pull for folding step 3 moves with component the simplest, the rolling friction structure 4 includes peace
Loaded on the symmetrically arranged guide rail 7 in the inner side of casing 2, and be respectively equipped with the track of guide rail 7 can be along its orbit rotation and linear displacement
Rolling bearing 8, rolled and touched by the bearing outer ring of rolling bearing 8 and guide rail 7, the bearing inner race of rolling bearing 8 passes through axle
The pull motion for folding step 3 in casing 2 is realized on the outside of the end for folding step 3.
Similarly, in order to use the simplest component to realize the fixation to the folding step 3 after expansion, the limiting bracket
5 are made of the single piece of metal part for being horizontally placed on lower surface at the front opening of casing 2, and by its side to folding the bottom of step 3
Support to consolidate the folding step 3 after expansion, so that the angle value for folding step 3 and horizontal plane is in the range of 20 ° -45 °
Fixed value.Embodiment as shown in Figure 1, it is that the limited support for the folding step 3 that 5 pairs of limiting bracket is 60 ° with horizontal plane angle is steady
The structural representation of Guan County's dress.
In order that moved along a straight line all the time when folding outside by rolling friction along guide rail 7 in casing 2 pull of step 3,
The guide rail 7 is realized by the positive stop strip 701 linearly set along installation on the outside of its track.Specifically, as shown in Fig. 2 institute
The edge of guide rail 7 can be installed in realize guiding and position-limiting action with U-shaped rubber or working of plastics by stating positive stop strip 701.
Use principle：Got on the bus for needs such as flat cars the vehicle of operation, by vehicular sideview installation casing 2, casing 2
Interior adaptation folds step 3, folds installation rolling bearing 8 on the outside of step 3 one end, by rolling bearing 8 along the guide rail 7 in casing 2
For linear motion to realize, easily pull folds step 3 in casing 2, folds step 3 and connects two folding lists by hinge 9
Member, and the limiting bracket 5 for folding step 3 after can consolidating expansion is set on the downside of the front end of casing 2, outside the guide rail 7 in casing 2
Side clamps positive stop strip 701 to ensure rolling bearing 8 all the time along straight-line rolling.Solve staff and easily go up lower platform whenever and wherever possible
Technical problem.In summary, the utility model, which also has, effectively utilizes vehicular sideview space, simple in construction, easy to operate fast
Victory, it is solid and reliable, the spy for convenience of getting on the bus is provided when vehicle appearance and terrain clearance is not influenceed for staff
Point.
Above-described embodiment, simply preferred embodiment of the present utility model, not it is used for limiting the utility model practical range,
Therefore all equivalence changes done with content described in the utility model claims, the utility model claims model all should be included in
