Technical Field
[0001] The utility model relates to a grounding device for a stacker when it is traveling, and belongs to the technical field of stacker equipment. Background Art
[0002] The stacker is an important equipment for port unloading operations. It is a mobile continuous bulk cargo stacking equipment, mainly suitable for powdery, granular, small block low-abrasive materials. Since the stacker equipment is relatively complex and has many rotation positions, it is very easy to generate static electricity. If the static electricity is allowed to be generated without release or damage to precision equipment such as electrical switches, it is necessary to install a grounding device for discharge protection. Since the stacker needs to continuously move, it is impossible to install a fixed grounding device. Only a grounding device that moves with the stacker can be installed. The existing stacker grounding device is a grounding plate, one end of which is connected to the stacker. The grounding plate is placed on the track and contacts the track by the gravity of the grounding plate. The disadvantages of this grounding form are: when the weight of the grounding plate is set to be small, the vibration of the large machine is very easy to drive its own vibration, so it is impossible to ensure that the grounding plate is in real-time contact with the track; when the weight of the grounding plate is set to be large, it is easy to cause the device to be top-heavy; and when there are debris on the track, it will also cause damage to the grounding device. Therefore, the reliability of the existing stacker grounding device is poor and cannot meet the needs of production. It is very necessary to improve it. Utility Model Content
