The tripod 1 is provided with a main support leg 11 and two auxiliary support legs 12. The main support leg 11 of the tripod 1 is supported at the top center of the outer surface of the steel pipe 3; the two auxiliary support legs 12 of the tripod 1 are located on both sides of the main support leg 11, and magnetic suction cups 2 are installed at the lower part. The two auxiliary support legs 12 are adsorbed on the outer surface of the steel pipe 3 through the magnetic suction cups 2.

[0018] The top of the tripod 1 is a mounting platform for devices such as RTK, optical measuring equipment, and reflecting prisms, and the RTK, optical measuring equipment, and reflecting prisms are fixed on the top of the tripod 1 .

[0019] Through the above-mentioned structural setting, the main leg 11 of the tripod 1 is supported on the top center of the outer surface of the steel pipe 3; the two auxiliary legs 12 are adsorbed on the outer surface of the steel pipe 3 through the magnetic suction cup 2. It is convenient to stably fix the tripod 1 on the outer surface of the steel pipe 3, so as to facilitate the installation of RTK, optical measurement equipment, reflection prism and other devices on the surface of the steel pipe for measurement, and the tripod 1 is not easy to slip or fall.

[0020] The magnetic suction cup 2 is detachably mounted on the auxiliary support leg 12 via the angle adjustment arm 4 .

[0021] One end of the angle adjustment arm 4 is fixed with the auxiliary support leg 12, and the other end is fixed with the magnetic suction cup 2. The direction of the magnetic suction cup 2 is adjusted by the angle adjustment arm 4 to adapt to the diameters of different steel pipes 3 on site.

[0022] like Figure 4 As shown, the angle adjustment arm 4 includes a first adjustment arm 41 and a second adjustment arm 42. One end of the first adjustment arm 41 and the second adjustment arm 42 are hinged together by a hinge shaft 43. The first adjustment arm 41 and the second adjustment arm 42 can rotate around the hinge shaft 43 to adjust the angle between the two and lock the angle between the two by a locking device; the other end of the first adjustment arm 41 is provided with a first clamping hoop 411, and the other end of the second adjustment arm 42 is provided with a second clamping hoop 421. The first clamping hoop 411 is detachably mounted on the lower part of the auxiliary support leg 12, and a clamping shaft 21 is vertically arranged at the top center of the magnetic suction cup 2, and the second clamping hoop 421 is detachably mounted on the clamping shaft 21.

[0023] The first clamp 411 and the second clamp 421 are both composed of two arc-shaped clamps, both ends of the clamps are provided with mounting ears, the mounting ears are provided with screw holes, and the two arc-shaped clamps are connected together by a screw with a butterfly-shaped handle passing through the screw holes.

[0024] The first adjusting arm 41 and the second adjusting arm 42 are made of ABS composite material, and the holding shaft 21 can be made of 304 stainless steel.

[0025] The hinge shaft 43 is a bolt, one end of the first adjustment arm 41 and the second adjustment arm 42 are both provided with a sleeve hole, and are sleeved on the bolt through the sleeve hole, and the locking device is a butterfly nut sleeved on the bolt.

[0026] like Figure 4 As shown, the second adjustment arm 42 and the first adjustment arm 41 are generally rod-shaped, and one end of both is provided with a sleeve hole for bolts to pass through. After adjusting the angles of the first adjustment arm 41 and the second adjustment arm 42, the butterfly nut is rotated to fix the angles of the first adjustment arm 41 and the second adjustment arm 42.
