Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a guiding device of a crane. Background Art

[0002] Pipe piles are divided into prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-walled pipe piles (PTC pipe piles) and prestressed high-strength concrete pipe piles (PHC pipe piles) according to the concrete strength grade and wall thickness. Cranes are required to transport the pipe piles.

[0003] The existing crane does not have a guide device, which is not convenient for guiding the displacement so that the middle section of the pipe pile is located at the center of the device body to maintain the lifting balance, and is not convenient for fixing and clamping both sides for anti-skid and safe lifting.

[0004] For example, a guide device of a pipe pile crane disclosed in Chinese patent CN217102694U is driven by a motor through a guide roller installed in the second mounting groove of a guide platform, and cooperates with a lower guide roller installed in the first mounting groove of the device body and an upper guide roller installed on the top of the device body by a guide roller frame, so that the pipe pile to be hoisted is guided to the inside of the device body, and the guide displacement makes the middle section of the pipe pile located at the center of the device body to maintain the hoisting balance. At the same time, a clamping seat with an anti-skid pad is driven by an electric telescopic rod to clamp and fix both sides of the pipe pile for anti-skid and safe hoisting and lifting. The structure is simple and the guide device is provided to facilitate the guided displacement so that the middle section of the pipe pile is located at the center of the device body to maintain the hoisting balance, and to facilitate the fixed clamping on both sides for anti-skid and safe hoisting and lifting.

[0005] However, during use, the device cannot move pipe piles of different diameters to the center of the device body because the upper and lower guide rollers are fixed in position. This has limitations in use and is less practical.
