[0002] The butterfly tray is a tray of a specific shape, mainly used in anchor support systems in industrial fields such as mining. Its shape is similar to the wings of a butterfly and has a good load-bearing effect. The butterfly tray can effectively transfer the thrust generated by the tightening torque of the nut to the top wall, thereby generating initial anchor force. At the same time, it can also transfer the pressure of the roadway top wall to the anchor rod, generating working resistance, jointly reinforcing the surrounding rock and preventing the displacement of the roadway top wall. As a key component in the anchor support system, the performance of the butterfly tray directly affects the support effect of the anchor rod. Its superior load-bearing capacity and structural design help to improve the stability and reliability of the entire support system.

[0003] During transportation and hoisting, butterfly pallets are generally stacked together in groups for packaging, such as cross stacking or alternating stacking. In order to increase the stability of the stacked pallets, steel bars, straps, wrapping films and other tools are used to reinforce and tighten the stack of pallets, and then the tightening tools are hooked with the hook of the hoisting equipment for hoisting. The whole process is very troublesome. Due to the difference in the number of pallets in a stack, manual adaptive tightening is required, which is inefficient. Therefore, the utility model proposes a special hoisting tool for butterfly pallets to solve the problems existing in the prior art. Utility Model Content
