FIG. 2 is a front view of the structure of the middle flat tank device of the present invention;

fig. 3 is a schematic structural view of the middle flat tank device according to the present invention.

In the figure: 1. the device comprises a vertical shaft flat tank device 11, a supporting claw 12, a supporting tank beam 13, a connecting rod 14, a conversion rod 15, a conversion shaft 16, a long shaft 2, a driving hydraulic cylinder 3, a well wall 4 and a cage.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

A vertical shaft horizontal tank device for a unilateral roadway mine comprises a lifting assembly, wherein the lifting assembly comprises a supporting claw 11, a supporting tank beam 12, a connecting rod 13, a conversion rod 14, a conversion shaft 15 and a long shaft 16.
