Specific implementation mode
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, from beginning extremely
Same or similar label indicates same or similar element or element with the same or similar functions eventually.Below with reference to
It is illustrative when the embodiment of attached drawing description, it is only used for explaining the utility model, and the limit to the utility model cannot be construed to
System.
With reference to the accompanying drawings of the specification and specific embodiment, invention is described in detail.
As shown in Figures 1 to 6, the utility model embodiment proposes that a kind of sliding platform with support construction includes flat
Platform 1, the platform 1 are connect with support construction 25, and the support construction 25 is set to 2 on chassis, and the chassis 2 includes platform framework
21, steering mechanism 22, driving mechanism 23, control system 24.
Specifically, the platform 1 include all around band be equipped with the upper flat plate 11 of 5 ° ~ 30 ° gradients and be connected therewith more
A platform leg 12.Normal operation（I.e. platform truck, which was not ground by the tested vehicle of very weight, causes platform 1 to move down）When, platform
Support leg 12 is liftoff about 14mm.The support construction 25 includes force-limiting device and fixed seat 251, and the force-limiting device includes power limit
Device mover 253 and force-limiting device stator 252 processed, make between force-limiting device mover 253 and force-limiting device stator 252 equipped with friction member
It obtains force-limiting device mover 253 and the opposite sliding of force-limiting device stator 252 needs to overcome certain resistance.The force-limiting device stator
