[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Please refer to Figure 2, the utility model provides a technical solution:

[0019] A stable hoisting device for steel members, including a hanging bracket 2 and symmetrically arranged guide plates 6. In the middle of the upper side of the hanging bracket 2, a lifting ring 1 is welded. In the middle of the surface of the guide plate 6, a rotating block 8 clamped outside the hanging bracket 2 is installed. Symmetrically arranged spiral springs 7 are installed between the hanging bracket 2 and the guide plate 6. Guide tubes 12 are evenly sleeved inside the guide plate 6. Mounting brackets 4 are symmetrically installed on the side surface of the guide plate 6. A motor 3 is fixedly installed on the mounting bracket 4. A rotating shaft 5 is installed on the motor shaft of the motor 3. Pulling ropes 9 are evenly wound on the surface of the rotating shaft 5. A stop block 10 is installed on the surface of the pulling rope 9. A counterweight ball 11 is installed at the end of the pulling rope 9. Through the setting of the counterweight ball 11, the irregular steel member itself forms a long strip structure, so that the center of gravity of the steel member is stably lowered, making it more convenient during hoisting.

[0020] The hanging bracket 2 is of a U-shaped structure.

[0021] The rotating block 8 is of a U-shaped structure. The rotating block 8 is movably connected to the hanging bracket 2, and with the reset of the spiral spring 7, the guide plate 6 is kept balanced during hoisting.

[0022] The pulling rope 9 is inserted into the guide tube 12. The pulling rope 9 is an elastic rope, and the elastic rope has elasticity, which can eject the counterweight ball 11 outward to adjust the center of gravity of the steel member.

[0023] The counterweight ball 11 is made of a steel ball, which plays a counterweight role to prevent the pulling rope from spreading outward.

[0024] The height of the stop block 10 is greater than the diameter of the guide tube 12. The existence of the stop block 10 provides resistance to the pulling of the pulling rope, facilitating the storage of energy for the pulling rope, so that the pulling rope can be placed on both sides of the steel member.

[0025] Working principle: When hoisting a steel member, the steel member is in the middle position of the hoisting device. Pass the hoisting rope through the lifting ring 1 and use a hook to hoist the steel member. During hoisting, turn on the switch of the motor 3, and the rotating shaft 5 will wind the pulling rope 9, thus tightening the pulling rope 9. Through the blocking of the stop block 10, energy is stored for the pulling rope 9, and then turn off the switch of the motor 3. Due to the elasticity of the pulling rope 9, the pulling rope 9 will be ejected to both sides of the steel member, and the pulling rope 9 is placed on both sides of the steel member, so that it is convenient to adjust the overall center of gravity of the steel member and make it more stable during hoisting.

[0026] The utility model pulls the pull rope 9 through the motor 3, and the elastic force of the pull rope 9 can eject the counterweight ball 11 outward, and the pull rope 9 is placed on both sides of the steel structure. Through the counterweight of the counterweight ball 11, it is convenient to control the center of gravity of the steel component, so that the center of gravity of the steel component is lowered, and it is more stable when lifting. Through the connection between the hanger 2 and the rotating block 8, it is convenient to adjust the angle of the hanger 2, and the spiral spring 7 plays a reset role, further increasing the stability of lifting the steel component. Through the setting of the stopper 10, the pull rope 9 can be stored, which helps to disperse the pull rope 9 and the counterweight ball 11 to both sides of the steel component. The utility model controls the pull rope 9, puts the pull rope 9 and the counterweight ball 11 on both sides of the steel component, so that it is convenient to control the center of gravity of the steel component and facilitate the smooth lifting of the steel component.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
