[0041] In this embodiment, the travel drive motor 8 adopts an energy-saving variable frequency motor with a long service life and low noise.

[0042] In an exemplary embodiment of the present application, both the driving wheel 9 and the driven wheel 10 are made of ductile iron.

[0043] In this embodiment, the self-friction effect of the ductile iron material is lower, which can reduce the friction loss between the driving wheel 9 and the driven wheel 10 and the track assembly 1, and improve the transmission efficiency.

The ductile iron material has good strength and hardness, which can improve the transmission stability and reliability of the driving wheel 9 and the driven wheel 10, and the ductile iron material has good shock absorption and noise reduction effects, which can reduce noise and vibration during transmission and improve the comfort of equipment.

[0044] In an exemplary embodiment of the present application, the first rail 101 and the second rail 102 are both I-shaped steel rails.

[0045] In this embodiment, the use of an I-beam track can provide a more stable and smooth running track, reduce the shaking or swinging of the grab bucket 12 during the lifting process, improve the safety and stability of the grab bucket 12 lifting, and reduce the possibility of accidental damage; in addition, the I-beam track can also increase the supporting area and withstand greater pressure, which is of great help in improving the load-bearing capacity and service life of the lifting mechanism 4 and the opening and closing mechanism 5.

[0046] In an exemplary embodiment of the present application, the lifting mechanism 4 and the opening and closing mechanism 5 are both electric hoists.

[0047] In an exemplary embodiment of the present application, both the lifting mechanism 4 and the opening and closing mechanism 5 are provided with a distance detection element 11 .

When the grab bucket 12 needs to be lifted or lowered, the steel cable of the lifting mechanism 4 is reeled in or released to realize the rising or falling of the grab bucket 12. When the grab bucket 12 needs to be opened or closed, the steel cable of the opening and closing mechanism 5 is reeled in or released to realize the opening or closing of the grab bucket 12. The electric drive structure design of the grab bucket 12 proposed in the present application is compact and light in weight. In addition, the change in the installation method makes it possible to move the electric hoist directly to the maintenance platform for maintenance when it fails, thereby reducing the safety risks of maintenance personnel. At the same time, the wear of the driving wheel 9 and the driven wheel 10 on the track is reduced, thereby greatly extending the life of the track.
