Description

Technical Field

[0001] The utility model relates to the technical field of cable reversing protection devices, in particular to a reversing protection device for power supply cables of a bucket wheel machine. Background Art

[0002] Bucket wheel excavator is a large-scale mechanical equipment used for unloading bulk goods such as ore and coal in port cargo yards, and adopts mobile high-voltage power supply cables. Since bucket wheel excavators often need to move during operation, when supplying power to both sides of the track with a long spacing, it is necessary to bend the cable at the middle cable reversing point back and forth to achieve the cable reversal, and then realize the power supply to the power points on both sides. Therefore, the cable reversing point of the bucket wheel excavator controls the reversal of the cable to ensure that the cable is smoothly retracted and released by the cable drum of the bucket wheel excavator and operates smoothly. Due to the large size of the bucket wheel excavator, the power supply cable on the bucket wheel excavator is very thick. The existing cable reversing point is a box installed above the reversing pit. The cable is placed on the box to achieve the reversal of the cable. In order to avoid the surrounding materials from falling and hitting the cables on the upper part of the box, causing the cables to be squeezed and rubbed, resulting in cable damage and safety accidents, the existing technology installs a protective device above the box to protect the upper part of the cable, but the existing protective device is an integrated design, which is inconvenient to disassemble. Once a component has a problem and needs to be replaced, the entire protective device can only be replaced, which increases the replacement cost. Utility Model Content
