The beneficial effects of the utility model are:At least two mounting hole groups can insert the various support shaft of different thicknesses,
Compared with prior art, the design of at least two mounting hole groups meets the installation requirements of different arms;By the way of inserting
The dismounting for making support shaft is more convenient, improves the removal efficiency of arm;Each mounting hole group is divided into corresponding including two
Mounting hole on installing plate so that support shaft can keep stress balance in the case where undertaking arm gravity, not need to carry out
It reinforces, so that installation pedestal structure is simpler.
The upper edge of the installing plate is bevel edge, and at least two mounting holes set on same installing plate are oblique along being parallel to
The extending direction on side is sequentially arranged.In the installation process of arm, which reduces installing plate upper edge to arm
Shielded area so that arm is easier to look for hole when mounted and is directed at inserting support shaft.
The installation pedestal is equipped with the fixed part for fixing on the ground.Installation pedestal is fixed on bottom surface to prevent
Arm moves during installation and experiment.
The fixed part is the fixation steel plate of installation pedestal bottom welding.
The bottom of the stent is equipped with walking mechanism to adapt to the arm of different length.Stent can move to adapt to difference
The length of arm.
The walking mechanism includes the pulley that the frame bottom is equipped with.
The walking mechanism further includes the guide rail for being set along arm in the extending direction of floor projection, on the guide rail
Guiding movement is provided with the pulley.It is slidably matched using the guiding of pulley and guide rail, further prevents arm in experiment process
In shake.
Two installing plate parallel interval arrangements of installation pedestal, installation pedestal further includes horizontal between two installing plates
To reinforcing plate.Lateral strengthening version can effectively prevent arm to shake while arm gravity is undertaken.
