[0029] In combination with Figures 2-4The lower side of the two extrusion blocks 21 is provided with a plurality of friction blocks 211, which increase the friction between the barrel segment and the extrusion block 21, and prevent the barrel segment from moving. The upper side of the upper beam 11 is provided with two lifting plates 112, and a plurality of connecting holes 113 are formed in the lifting plates 112. The lifting hook of the crane is connected to the U-shaped beam 1 through the connecting holes 113. The lifting hook is connected to different connecting holes 113, so that the center of gravity of the U-shaped beam 1 and the up-down angle of the lifting cone barrel opening can be changed. The upper side of the lower beam 12 is provided with a plurality of protruding blocks 121, and a sliding groove two 122 is formed in the lower beam 12. The sliding groove two 122 is provided with a blocking assembly 3. The protruding blocks 121 increase the contact area between the lower beam 12 and the barrel segment, preventing the barrel segment from sliding off.

[0030] In combination Figure 2 , Figure 5 The blocking assembly 3 includes a pressure receiving block 31, which is in sliding connection with the sliding groove two 122. The pressure receiving end of the upper side of the pressure receiving block 31 is arranged in an inclined manner. A connecting plate 32 is mounted on one side of the pressure receiving block 31. A rotating column 33 is provided on the end of the connecting plate 32 away from the pressure receiving block 31. The rotating column 33 is in rotating connection with the lower beam 12. A right-angle groove 331 is formed in the rotating column 33. The free end of the connecting plate 32 is located in the right-angle groove 331. A blocking plate 34 is mounted on one side of the rotating column 33. When the U-shaped beam 1 is moved, the lower beam 12 enters the inside of the barrel segment. One side of the barrel segment extrudes the pressure receiving end of the pressure receiving block 31, so that the pressure receiving block 31 moves downward along the sliding groove two 122, thereby driving the connecting plate 32 to move downward. The free end of the connecting plate 32 presses the right-angle groove 331 of the rotating column 33 downward, so that the rotating column 33 rotates, thereby driving the blocking plate 34 to rotate, until the blocking plate 34 is in a vertical state.

After the barrel segment is lifted by the U-shaped beam 1 to the predetermined position, the U-shaped beam 1 is moved downward, and the barrel segment is placed on the ground. At this time, the upper side of the inner wall of the barrel segment no longer extrudes the pressure receiving block 31. The spring 313 reversely acts on the pressure receiving block 31, so that the pressure receiving block 31 moves upward, thereby driving the connecting plate 32 to move upward. The free end of the connecting plate 32 extrudes the right-angle groove 331 of the rotating column 33 upward, so that the rotating column 33 reversely rotates, thereby causing the blocking plate 34 in the vertical state to change to the horizontal state, so as to no longer block the barrel segment, facilitating the workers to take down the barrel segment from the lower beam 12.

[0032] Working principle: move the U-shaped beam 1 until the upper side of the barrel section and the lower beam 12 are completely attached, then rotate the rotating disc 26, the rotating disc 26 drives the connecting column 25 to rotate, thereby driving the rotating shaft 24 to rotate, so that the two gears 23 rotate, the gear 23 drives the rack plate 221 to move downward, thereby driving the moving plate 22 to move downward, so that the extrusion block 21 moves downward, the two extrusion blocks 21 extrude the upper side of the outer surface of the barrel section, so that the barrel section is fixed between the extrusion block 21 and the lower beam 12, preventing the U-shaped beam 1 from shaking and causing the barrel section to fall off.
