Description

Technical Field

[0001] The utility model relates to the technical field of turnover tooling, in particular to a counterweight welding turnover tooling. Background Art

[0002] A counterweight refers to the extra weight or force applied to a mechanical system to maintain balance. In some mechanical devices or structures, imbalance may occur due to design or operation reasons. In this case, a counterweight needs to be applied to eliminate the imbalance.

[0003] During the installation of the counterweight, in order to ensure stability, it is usually necessary to weld it in the mechanical equipment. At this time, the loading and positioning of the counterweight often requires transfer equipment such as forklifts. This transfer equipment can perform a certain amount of pushing and transporting, and place it at a designated position for welding, but it cannot be flipped over, and cannot be positioned and placed at a specified angle, such as switching between horizontal and vertical placement. Therefore, it is necessary to design a flipping tool that can assist in flipping to solve the corresponding technical problems. Among them, the common flipping tool does not have any anti-fall protection structure during the flipping process. When a large-mass counterweight is flipped, there is a certain inertia after the flip. Without corresponding protection, there may be a risk of falling from the flipping tool, reducing the safety of the flipping work. Utility Model Content

[0021] The synchronization component includes a limit groove 24 and a synchronization gear plate 32. The limit groove 24 is opened in the middle position of the side wall of the right-angle groove 21. The end of the synchronization gear plate 32 is fixed on the right-angle bracket 3 and is slidably connected in the limit groove 24. The middle position in the limit groove 24 is rotatably connected with a transmission gear 25, and the transmission gear 25 is meshed with the synchronization gear plate 32. Two synchronization gear plates 32 are slidably connected in the same limit groove 24. The two synchronization gear plates 32 are fixed on different right-angle brackets 3 away from each other at one end, and the two synchronization gear plates 32 are respectively located on both sides of the transmission gear 25.

[0022] The fixing assembly includes a positioning rod 34 and a positioning hole 26. A fixing plate 33 is fixed to the outer wall of the right-angle bracket 3. The positioning rod 34 passes through the fixing plate 33 and is slidably connected to the fixing plate 33. The positioning holes 26 are opened on the side wall of the right-angle groove 21 and are evenly distributed. The bottom of the positioning rod 34 is inserted into the positioning hole 26. A pull plate 35 is fixed to the upper end of the positioning rod 34. A fixing spring 36 is fixed between the pull plate 35 and the fixing plate 33. The fixing spring 36 is located on the outer periphery of the positioning rod 34.

[0023] The driving assembly includes a worm 13 and a worm wheel 23. A driving groove 12 is opened at the bottom of the rotating groove 11. The worm 13 is rotatably connected in the driving groove 12.
