It is fixed to determine beam 31.First guide part 22 is used for the guide pad 21 of engaging battery 33, and the second guide part 24 is fixed for engaging vehicle body
The limiting section 32 of beam 31.
Vehicle body of the vehicle body fixed beam 31 in a manner of welding or be threadedly engaged with vehicle 30 is fixed, the welding of limiting section 32 or spiral shell
Line is bonded on the opposite surface of two vehicle body fixed beams 31.
First guide part 22 and the second guide part 24 all have for guiding vehicle 30 along first direction X and second direction Y
The inclined guide surface of positioning.
First guide part 22 and the second guide part 24 are guiding fork.
As seen in figures 3-6, two the first guide parts 22 and two the second guide parts 24 have first in opposite side
Inclined guide surface 23；Two the first guide parts 22 and two the second guide parts 24 in the side being away from each other there is the second inclination to lead
To face 25.There is third inclined guide surface 26 on the inside of the recess portion of first guide part 22 and the second guide part 24.
Although not illustrating in figure, be all provided in the first inclined guide surface 23 and the second inclined guide surface 25 it is fluted, in groove
It is embedded in wear-resisting and self-lubricating material.Preferably, material is MC nylon or graphite.
The tilt angle of inclined guide surface is less than or equal to 30 °.
When the first guide part 22 and the second guide part 24 move on third direction Z and move closer to battery 33,
The second inclined guide surface 25 of vehicle body fixed beam 31 is first contacted on two direction Y or first contacts the side of the battery 33 on cable 30
First inclined guide surface 23 can apply extruding force to vehicle 30 can be light in the case where changing the auxiliary of ground roll device 11 of level platform 10
Pine nut shows aligning of the vehicle 30 on second direction Y.Similarly, when the first guide part 22 and the second guide part 24 respectively with
When guide pad 21 and limiting section 32 engage, third inclined guide surface 26 can apply extruding force to guide pad 21 and limiting section 32, from
And realize aligning of the vehicle 30 in a first direction on X.Similarly, for Z axis direction of rotation, when the first guide part 22 and
For two guide parts 24 when moving on third direction Z and moving closer to battery 33, the first guide part 22 and the second guide part 24 are
