By the way that multiple limiting devices are arranged, it is equivalent to one cylinder of setting, base body is set on cylinder, prevents from turning
During dynamic, deviate, de-orbits on the inside or outside of base body phase, improve the stability of entire dome, while limiting dress
It sets and is contacted with the inner peripheral surface of base body by limited roller, in rotation process, limited roller also rotates base body, reduces
The frictional force of limiting device and base body reduces energy consumption.
It is further improved, the base body is welded to form by angle steel and steel plate, and angle steel constitutes frame, is adopted around frame
It is wrapped up with steel plate, multiple deep floors is welded on frame, improve the intensity of domed base.
It is further improved, the periphery of the base body is provided with shirt rim, and the shirt rim includes rake and vertical portion, skirt
While being connected by the periphery of rake and base body, the angle of rake and vertical portion is 110 degree.It is prevented by the way that shirt rim is arranged
Sundries enters in driving device, multiple idler pulley devices and limiting device, influences its normal rotation, while being also prevented from idler and leaning on
Closely, safety is improved.
Compared with prior art, the present invention has the advantages that：
By the way that multiple limiting devices are arranged, it is equivalent to one cylinder of setting, base body is set on cylinder, prevents from turning
During dynamic, deviate, de-orbits on the inside or outside of base body phase, improve the stability of entire dome, while limiting dress
It sets and is contacted with the inner peripheral surface of base body by limited roller, in rotation process, limited roller also rotates base body, reduces
The frictional force of limiting device and base body reduces energy consumption.
