Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric hoist technology, and more specifically, to an electric hoist balancing structure. Background Technology
[0002] An electric hoist is a special lifting device installed on overhead cranes and gantry cranes. It consists of mechanical and electrical parts and is used in industrial and mining enterprises, warehouses, docks and other places. The working principle is to be powered by a sliding contact line and operated by a handle. The control circuit in the control box controls the lifting motor and travel motor of the electric hoist to achieve the purpose of lifting equipment.
[0003] Currently, some electric hoists on the market are typically installed and used on the tracks of overhead cranes or gantry cranes, where the traveling wheels are moved by a motor. However, during use, the drive motor can only drive the traveling wheels on one side of the track, while the traveling wheels on the other side are used as driven wheels. Therefore, during operation, the traveling wheels on both sides are prone to imbalance, which can lead to abnormal operation of the traveling mechanism and reduce the service life of the components.
[0004] To address the aforementioned problems, this application proposes a balancing structure for an electric hoist. Utility Model Content
[0005] To address the problems in related technologies, this utility model provides a balancing structure for an electric hoist that can simultaneously drive the two walking wheels on both sides to work together, effectively ensuring the balance of the two walking wheels and improving the service life of the components.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] An electric hoist balancing structure includes a track body, a hanging assembly, and a traveling assembly. The hanging assembly is installed below the track body, and a part of the hanging assembly is installed on the traveling assembly.

An adjusting screw is installed in the middle of the upper end of the adjusting seat, and the other end of the adjusting screw passes through the top plate. Adjusting nuts are installed on the adjusting screws on the upper and lower sides of the top plate.
[0010] As a further embodiment of this utility model, a slider is installed at the bottom center of the top plate, a ball bearing is rotatably installed at the bottom of the slider, the slider is slidably connected to the groove at the upper end of the track body, and a motor synchronizer is installed at the upper end of the top plate.
[0011] As a further embodiment of this utility model, the first drive motor and the second drive motor work synchronously through a motor synchronizer.
[0012] As a further embodiment of this utility model, the hanging assembly includes a connecting hook, which is installed on a hanging rod between the two equipment plates, and a housing is installed at the bottom end of the connecting hook.
