The present disclosure provides a grinding robot for an inside wall of a small diameter pipe. The grinding robot includes a grinding device, a transmission device, and a driving device. By arranging the grinding robot into the above three portions, the overall bending pipe passability of the robot can be increased, which is convenient for the grinding robot to grind the small diameter pipe. A first gimbal and two second gimbals provided in the transmission device enable the grinding robot to flexibly pass through bends of the pipe, and enable a grinding driving force to be variably transmitted to the grinding device. When the grinding body rotates and contacts a pipe wall, a reaction force of the pipe wall on the grinding body is balanced by an adjusting spring adjustment force in a balance adjusting device and a self-weight of a grinding body.

Grinding robot for inside wall of small diameter pipes

An actively driven spiral pipeline robot is disclosed, comprising: a body, a power device, a driving shaft, an axle, a driving wheel carrier mounted at one end of the body, and a variable diameter mechanism disposed on the driving wheel carrier. The axle is disposed on the variable diameter mechanism. A driving wheel is fixedly mounted on the axle. The driving shaft and the axle are connected via a connector. The driving shaft is further connected with an output shaft of the power device via a transmission device. The present invention has following beneficial effects: a scope of application of the robot is expanded, an operation is stable, and an axial force is large. In addition, an axial position of the robot is adjusted by controlling an operation of the driving wheel, and an adjustment precision is high.
