Description

Technical Field

[0001] The utility model belongs to the technical field of excavators, and in particular relates to a cable frame of a towed electric excavator and the towed electric excavator. Background Art

[0002] The towed electric excavator connects external power such as grid power and external battery to the excavator through cables. The existing towed electric excavator generally has two power supply lines: upper body supply line and lower body supply line.

[0003] For the upper body cable entry, a cable bracket is set on the upper body of the excavator, and the power cable is installed on the cable bracket. The cable bracket rotates with the upper body. The upper body of the excavator with this cable entry method can only rotate in a small range, and the rotation angle is generally ≤±150°. If the angle exceeds this, the cable will be entangled with the fuselage and the cable will be pulled and damaged. The excavator cannot rotate 180° to load the vehicle or perform other operations, which is extremely inconvenient to use.

[0004] The cable bracket for the lower body incoming lines is usually set on the running frame. The cable bracket does not rotate with the upper body and does not affect the rotation of the upper body. However, the cable bracket for the lower body incoming lines is located low and the cable bracket often collides with the gravel on the ground. If the structural strength of the cable bracket is not high, it is easy to cause damage to the cable bracket.

[0005] In addition, the existing towed electric excavator often drags the cable during operation. During the long-term dragging process, the cable and the excavator connection terminal will become loose, causing the excavator to stop working and affecting the progress of the project.
