The utility model provides a circular tubular product lifting device, includes lifting hook body and magnetic force seat, wherein: the lifting hook body comprises an upper cross rod 201, a lower cross rod 206 and a vertical rod 207, wherein the outer ends of the upper cross rod 201 and the lower cross rod 206 are connected through the vertical rod to form a U-shaped structure, an opening is formed in the side face of the U-shaped structure and is used for being inserted into an upper port of a pipe 3, and the pipe 3 can be hooked by combining with the illustration shown in fig. 1, the lower cross rod 206 supports the pipe 3, the upper cross rod 201 and the lower cross rod 206 can form a clamping state on the end face of the pipe 3 to a certain extent, and meanwhile, a lifting hole 202 is formed in the upper cross rod 201 in a penetrating manner so as to penetrate through a steel wire rope 1, so that the pipe 3 is lifted; in this embodiment, the inner end of the bottom cross bar 206 is fixed with the magnetic seat 205, before hoisting, the switch of the magnetic seat 205 is unscrewed, so that the magnetic seat 205 is not easy to separate from the circular pipe 3 due to the adsorption of the steel material in the circular pipe 3, and the inner end of the bottom cross bar 206 is kept upward due to the upward force generated by the adsorption, so that the lifting hook body is not easy to separate from the pipe 3, the construction safety is ensured, and after hoisting, the hoisting tool 2 can be taken out by closing the switch of the magnetic seat 205. The magnetic base is a prior art, or called a magnetic gauge base, when the switch is unscrewed, the switch has strong magnetism, and when the switch is closed, the switch does not have magnetic force, in addition, because the round pipe 3 has a certain radian, when the magnetic base 205 is installed, the upper surface is slightly lower than the upper surface of the bottom cross bar 206, so that the side, far away from the bottom cross bar 206, of the magnetic base 205 is closer to the inner wall of the pipe 3 when being hoisted. The magnetic base 205 and the bottom rail 206 may be fixed by welding. The upper cross bar 201, the lower cross bar 206 and the vertical bar 207 of the hook body are preferably of an integral structure and are cut from sheet materials.
