[0002] A wind turbine generator set is composed of a wind rotor and a generator. The wind rotor includes components such as blades, a hub and reinforcements. The wind rotor has the function of generating electricity and driving the generator to rotate when rotated by wind. When the blades of a wind turbine generator set fail, maintenance personnel are required to climb to the vicinity of the blades for maintenance. However, currently maintenance personnel usually use cloth bags as storage containers for maintenance tools.

[0003] According to a publicly disclosed tool box for repairing blades of a wind turbine generator set (publication number: CN210790927U), a tool box for repairing blades of a wind turbine generator set in the above application includes a main tool box, two moving wheels are fixedly installed on the left and right sides of the bottom of the main tool box, a telescopic push rod is fixedly installed on the rear side of the main tool box, and a storage slot is opened on the front side of the main tool box.

[0004] However, in a high-altitude environment, if the tools in the toolbox are not properly placed, sudden wind or operational errors may cause the tools to fall. In this case, the fallen tools may cause serious injury or damage to the personnel or equipment below, and may also trigger a chain reaction, resulting in work interruptions, project delays or other safety risks. In view of this, we propose a maintenance toolbox that can prevent falling. Utility Model Content

The winding roller winds up the connecting rope, so that the interior of the tool box remains tidy and orderly, and the connecting rope is prevented from being scattered in the tool box and affecting the storage and use of other tools. The rotation of the winding roller drives the two-way lead screw to rotate through the transmission of the belt. The rotation of the two-way lead screw causes the movable block to reciprocate laterally. The movable block allows the connecting rope to be evenly wound on the outer wall of the winding roller to prevent the rope from being entangled and knotted, ensuring the neat arrangement and normal retraction and release of the connecting rope. The magnetic part is magnetically connected to the tool body to further fix the tool body to prevent the tool body from shaking.

[0020] 2. The anti-drop maintenance tool box has grooves set up to place screws, nuts and other parts in the grooves. The parts are magnetically attracted to magnets, making it convenient for maintenance personnel to take them out at any time, preventing them from accidentally falling or losing during maintenance, reducing the time of searching for parts, and improving work efficiency and safety.

[0028] The inner wall of the box body 2 is rotatably connected with a bidirectional screw rod 12, and the side wall of the bidirectional screw rod 12 is threadedly connected with a movable block 13. A through hole is opened on the surface of the movable block 13, and the connecting rope 8 passes through the through hole. The side wall of the bidirectional screw rod 12 is transmission connected with the winding roller 7 through a sleeved belt 14, and the side wall of the winding roller 7 is fixedly connected with a coil spring 16, and the end of the coil spring 16 away from the winding roller 7 is fixedly connected to the inner wall of the shell 6.

[0031] In the utility model, when in use, the tool body 9 is taken out, driving the connecting rope 8 to be pulled out, and the connecting rope 8 drives the winding roller 7 to rotate forward, and the coil spring 16 undergoes elastic deformation. After use, the tool body 9 is magnetically connected to the magnetic part 11, and the winding roller 7 winds up the connecting rope 8. The limit frame 10 resists the tool body 9. The rotation of the winding roller 7 drives the bidirectional screw rod 12 to rotate through the transmission of the belt 14. The rotation of the bidirectional screw rod 12 causes the movable block 13 to reciprocate laterally, guiding the winding of the connecting rope 8, and placing screws, nuts and other parts in the groove 17. The parts are magnetically attracted to the magnet 4, which is convenient for maintenance personnel to take at any time.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
