Vertical pipeline aligning device for buried sewage treatment plant

The utility model discloses a buried sewage treatment plant pipeline vertical aligning device which comprises an upper rotating disc, a supporting rod, a clamping plate, a spring, a lower chassis, a limiting bolt, a limiting disc, a sliding groove, an upper handle, a lower handle, a base, a sliding groove base and a rubber pad. The spring arranged on the side face of the device continuously exerts opposite circumferential tension on the upper rotary disc and the lower base plate of the device, the upper rotary disc drives the supporting rod to rotate, the shaft drives the clamping plate to move on the grooved rail, friction force is increased through the rubber pad of the clamping plate, and therefore the vertical pipe is tightly clamped, and the limiting plug pin and the limiting disc can control the opening and closing angle of the supporting rod. The device can be suitable for more vertical pipes with different pipe diameters, and can be stably placed on the base, so that workers can conveniently carry out
