The application discloses a portable adjustable pipe supporting and carrying trolley, and belongs to the technical field of carrying trolleys. The trolley comprises a trolley frame, two running wheels and a gripping handle. The two running wheels are respectively arranged on the two sides of the trolley frame. The gripping handle is arranged on the middle part of the trolley frame. An extension part is fixedly arranged on the top of the trolley frame. A center rod is fixedly arranged on the top of the extension part. Pipe tongs are rotatably connected to the two ends of the center rod. A working cavity is arranged between the center rod and the extension part. A rotating handle is movably arranged on the side wall of the extension part. A placing groove is arranged on the side wall of the extension part. A rotating mechanism for driving the two pipe tongs is arranged in the working cavity. The pipe tongs clamping and the trolley carrying are combined, portable clamping and carrying of pipes with different diameters are realized, the labor intensity is effectively reduced, and the pipe carrying efficiency and safety are improved.

The utility model provides a kind of high-precision robot joint gear transmission structure, it is related to planetary gear technical field, comprising: three planetary gear sets, each planetary gear set includes two gears connected and coaxially arranged, two gears are respectively gear located above as first planetary gear and gear located below as second planetary gear, the first planetary gear and the second planetary gear are all unevenly distributed gear number gear, first flat side and second flat side are respectively provided on the second planetary gear and the first planetary gear;Planet carrier.The utility model has beneficial effects: by adopting three planetary gear sets and the first planetary gear and the second planetary gear are all unevenly distributed gear number gear, and first flat side and second flat side are respectively set on it, cooperate with the mark on planet carrier, the accurate tooth and meshing of planetary gear set are realized, effectively improve transmission accuracy, reduce error accumulation, ensure the high-precision control of robot joint movement.
