[0020] The present invention will be further explained below in conjunction with the accompanying drawings. The structure and principle of this device are very clear to those in the field.
[0021] Such as figure 1 , 2 As shown, the cement pipe is laid flat, the horizontal suspension beam (1) is suspended above the pipe section, the two vertical arms (2) naturally hang down on both sides of the pipe section, and the round bolt (4) is inserted into the pipe section lifting hole through the pin sleeve (5) The inner hoisting pipe section and the wing-shaped baffle (8) restrict the pipe section from turning over and keep the pipe section stable. Such as Figure 5 As shown, the pin sleeve (5) is installed in the ball seat and can be rotated universally to facilitate the insertion and extraction of the round plug. Before lifting, insert the safety pin (7) to prevent the round pin from loosening and exiting, and to ensure the safety of lifting.
