The invention belongs to the field of double-beam bridge cranes, and particularly relates to a rail gnawing prevention double-beam bridge crane which comprises a rail and a crane body which are installed on a plant, the crane body is in contact with an adjusting box, a walking box is fixedly connected to the adjusting box, and driving wheels are arranged in the walking box. A rail gnawing prevention adjusting mechanism is arranged in the adjusting box, a replacement mechanism is arranged on the driving wheel, and a transverse driving base is arranged on the crane body. By additionally arranging the adjusting box, the screw rod, the threaded cylinder and other structures on the crane main body, the position of the driving wheel in the walking box can be adjusted through threaded fit between the screw rod and the threaded cylinder in the maintenance process of the driving wheel, so that the center line of the driving wheel and the center line of the track are located on the same straight line; therefore, rail gnawing can be effectively avoided.

    本发明属于双梁桥式起重机领域,具体涉及一种防啃轨的双梁桥式起重机,包括安装在厂房上的轨道和起重机主体,所述起重机主体上接触有调节箱,所述调节箱上固定连接有行走箱,所述行走箱的内部设置有驱动轮,所述调节箱的内部设置有防啃轨调节机构,所述驱动轮上设置有更换机构,所述起重机主体上设置有横向驱动座。本发明通过在起重机主体上加设调节箱、螺杆与螺纹筒等结构,在对驱动轮检修的过程中可以通过螺杆与螺纹筒之间的螺纹配合带动行走箱内部的驱动轮位置进行调节,使得驱动轮的中心线与轨道的中心线处于同一直线处,从而可以有效的避免啃轨。
