[0034] When the utility model is used, the bent part of the tower pipeline is placed on the ground, and the operator operates the tower crane to move the device to a suitable position, and with the assistance of the ground staff, the clamping jaw 803 is aligned with the tower pipeline. After alignment, the oil cylinder 7 is controlled to contract through the console, and the oil cylinder 7 drives the fixed plate 801 to move vertically upward, and the clamping jaw 803 is pulled upward through the slider 804 at the bottom of the fixed plate 801.

[0035] After the clamping is completed, the tower crane is operated to move the tower-attached pipeline to the docking position of the tower equipment. If an error occurs, the operator can use the tower crane console to control the rotation of the motor 105 according to the command of the on-site foreman. The motor 105 drives the bearing inner ring 6 to rotate through the driving gear 106, and drives the clamping mechanism 8 to rotate synchronously through the bearing inner ring 6, thereby driving the tower-attached pipeline to rotate, thereby achieving the effect of correcting the error. After the correction is completed, the tower crane is operated to lower the tower-attached pipeline to complete the docking, thereby achieving the effect of facilitating the correction of the error.

[0036] After the docking is completed, the cylinder 7 is controlled to extend through the console, and the cylinder 7 drives the fixed plate 801 to move vertically downward, and the clamping claw 803 is pulled downward through the slider 804 at the bottom of the fixed plate 801. After the clamping claw 803 is pulled, under the joint action of the limiting column 607, the limiting groove 805, and the limiting rod 806, the slider 804 slides from both ends to the middle in the slide groove 802, and at the same time rotates in the opposite direction along the limiting rod 806 until the clamping is released.
