The bottom side of the tripod 1 is 900mm long, the two short sides form a 90-degree angle, the short right-angle side is 300mm long, and the long right-angle side is 850mm long. The tripod axle pin 6 is made of φ48 steel pipe with a wall thickness of 3mm and welded to the top of the tripod 1. The four tripod rollers 5 are made and installed with 8-inch rubber bearing rollers.
[0018] The cross arm steel pipe 2 for holding the geomembrane coil is made of φ48 steel pipe with a wall thickness of 3mm. The two ends of the steel pipe are processed with external threads. The length of the steel pipe is determined according to the width of the coil. The connecting pipe of the connection limiter 3 is made of φ50 seamless steel pipe with a wall thickness of 3mm. The length of the connecting pipe is 180mm. One end is processed with internal threads and connected to the threaded end of the cross arm steel pipe 2. The other end is connected to the tripod axis pin 6 with a socket and fixed with a fixed through pin 4. The fixed through pin 4 is made of φ16 solid round steel; the connection limiter 3 is an annular plate with an outer diameter of 200mm, made of 2mm steel plate, and welded in the middle of the connecting pipe.
[0019] like Figure 1 and Figure 2 As shown. Both ends of the cross arm steel pipe 2 are coaxially fixedly connected with an annular connection stopper 3, and the connection stopper 3 is connected to the external thread at the end of the cross arm steel pipe 2 through an internal thread. The connection stopper 3 and the cross arm steel pipe 2 are connected in the form of a threaded connection, which can conveniently adjust the distance between the connection stopper 3 and the geomembrane roll 8 on the cross arm steel pipe 2. In addition, the auxiliary device is easy to assemble.
