For solving the problems of the technologies described above, the utility model by the following technical solutions.

A kind of rail transport transfer, comprise chassis and bearing tray, be installed with rotating shaft on the described chassis, bearing tray is located at the upper end of rotating shaft by bearing holder (housing, cover), be provided with the bearing assembly that can rotate around the axis between chassis and the bearing tray, described bearing tray is provided with track.

Described bearing assembly comprises rolling disc and is fixed on the rolling disc and equally distributed a plurality of sleeve pipe, described rolling disc is located at the middle part of rotating shaft by bearing holder (housing, cover), be provided with the rolling bearing ball in the described sleeve pipe, described rolling bearing ball top contacts with bearing tray, and the bottom contacts with the chassis.

Described rolling disc is provided with equally distributed a plurality of tunneling hole.

The top of described rotating shaft is provided with the top nut, is covered with over cap on the nut of described top.

Described chassis is provided with a circle shrouding along periphery.

Described bearing tray is provided with brake bar, the other sprag that cooperates with brake bar that is embedded with of bearing tray.

The bottom on described chassis is provided with the anchorage bar.

Compared with prior art, advantage of the present utility model just is:

1, changed traditional rail transport steering mode, realized that no track switch transportation turns to, and is applicable to light rail hauling operations at different levels;

2, simple in structure, can make at the construction field (site), material requested and facility all can be bought on market, and manufacturing and mounting cost are low, and engineering reliability is strong, only need regularly increase lubrication oil and safeguard, and is easy to use, long service life, maintenance cost is low;

3, be provided with the bearing assembly that can rotate around the axis between chassis and the bearing tray, make bearing tray even, can effectively prevent the bearing tray distortion, guarantee the precision of orbital docking at the supporting lower stress of bearing assembly;

4, the chassis is provided with a circle shrouding along periphery, prevents that lubrication oil from leaking outside, and stops that dregs enters rotation system, avoids dregs that rotation system is caused wearing and tearing, guarantees to rotate smooth and easy;

5, bearing tray is provided with the brake bar that can thereupon rotate, the bearing tray side is embedded with sprag that cooperate with brake bar, fixed, when the brake bar that rotates with bearing tray touches sprag, the track on the bearing tray is accurately docked with its peripheral track;

6, can be widely used in the construction and the production operation of mine, tunnel, underground construction and other employing rail transport, have a extensive future.
