[0028] Working principle: In actual use, the device first places the large-diameter reinforced concrete tongue-and-groove pipe that needs to be operated in a fixed position, and then moves the device through the brake wheel 2 at the bottom of the supporting base plate 1.

It can also be suitable for large-diameter reinforced concrete tongue-and-groove pipes of various lengths, which greatly improves the versatility and applicability of the equipment.
