Description

Technical Field

[0001] The utility model relates to the technical field of lifting machinery, in particular to a horizontal wheel device with adjustable gap. Background Art

[0002] Horizontal wheel devices are important components in the lifting and transportation industry and automated production line equipment. Some cranes with high positioning accuracy often use horizontal wheel devices to ensure the accuracy of the trolley travel mechanism. For example, the horizontal wheel device disclosed in patent document CN205838365U adopts a fixed structure and cannot adapt to the gap adjustment requirements under different working conditions. While CN201330122Y involves a simple adjustment structure, it has low adjustment accuracy and lacks a reliable locking mechanism. Vibration during equipment operation can easily cause gap changes, reducing the equipment's service life and work efficiency and increasing maintenance costs. Therefore, we propose a horizontal wheel device with adjustable gap. Utility Model Content

There is no need to disassemble parts during the entire operation, and the gap setting and mechanical locking can be completed with a single operation interface.
