Embodiments of the invention

The present invention will be further described below in conjunction with the accompanying drawings.

A specific embodiment 1 of the European double-girder bridge crane of the present invention, as shown in FIG. 1 to FIG. 7, includes a small frame 1, a wheel set drive motor 2, a first wheel set 4, a drive shaft 6, and a first The second wheel set 7 and the electric device 8, the wheel set drive motor 2 is a three-in-one speed reducer motor, the wheel set drive motor 2 is fixed to the outer side of the small frame 1 by the motor connection device 3, and the electric device 8 is disposed inside the small frame 1 The wheel set drive motor 2 is arranged side by side with the electric device 8, the first wheel set 4 and the second wheel set 7 are arranged side by side at the bottom of the small frame 1, the wheel axle of the first wheel set 4 is a double output shaft, and the wheel set drive motor 2 driving the first wheel set 4 to rotate, the wheel axle of the first wheel set 4 is coupled to the drive shaft 6 via a coupling 5, and the drive shaft 6 drives the second wheel set 7 to rotate, thereby realizing the first wheel set 4 and the second wheel Group 7 rolls on the main beam 9 to effect the movement of the crane trolley.

The wheel set drive motor 2 is disposed outside the small frame 1 to avoid occupying the inner space of the small frame 1 and further providing installation space for the electric device 8. At the same time, the wheel set drive motor 2 is disposed outside the small frame 1 and can be mounted on the crane The drive motor 2 is inspected on the main beam 9, and the inspection operation is more convenient.
