At this time, the worm wheel 604 that is engaged with the first worm 602 and the second worm 603 at the same time moves along the first direction, so that the movable frame 611 and the upper structure follow the worm wheel 604 to move in the first direction, completing the adjustment of the yaw clamp in the first direction position; then the first worm 602 and the second worm 603 rotate in opposite directions. At this time, the worm wheel 604 that is engaged with the first worm 602 and the second worm 603 at the same time rotates, and drives the gear 605 to rotate synchronously through the connecting shaft 610, so that the rack 606 that is engaged with the gear 605 moves relative to the movable frame 611 in the second direction. At this time, the third guide rail 612, the connecting plate and the tray 1 all move synchronously in the second direction driven by the rack 606, completing the adjustment of the yaw clamp in the second direction position. At this time, the yaw clamp is in the operating installation position.

[0066] The yaw clamp is generally installed at a height of 2m. During the traditional installation process, one or two people are required to lift the yaw clamp completely above their heads. If the manpower is insufficient or the two people do not cooperate properly, the yaw clamp may fall out of their hands and easily injure the workers. The use of this replacement tool can completely replace manual lifting work. First, the tray 1 of the replacement tool is equipped with a limit column, which can completely fix the yaw clamp on the tray 1; secondly, the first drive member 2 is used to lift the tray 1 to lift the yaw clamp, which solves the safety hazard caused by manual lifting, ensures the personal safety of the workers, and reduces the strength requirements of the workers; it also solves the time-consuming and labor-intensive problem of manually lifting the disassembled yaw clamp to place it on the platform, and improves the efficiency of yaw clamp disassembly and installation; finally, the workers can use their hands to provide auxiliary adjustment of the center of gravity of the replacement tool, thereby greatly improving the safety of the yaw clamp replacement work.

[0067] The pallet 1 of the replacement tool is installed by means of bolts and plug-in structures, and has the advantage of convenient disassembly and assembly. By utilizing this advantage, yaw clamps of different brands, sizes and models can be replaced and installed by replacing pallets 1 of different types. Even other functional pallets can be made to achieve the installation and replacement of other heavy (about 100 kg) equipment at high places (about 2 meters).
