Description

Technical Field

[0001] The invention relates to a stacker in a large cold storage, and in particular to a follow-up cleaning device and a cleaning method for frost on two power wheel treads on a ceiling rail of the stacker in the large cold storage. Background Art

[0002] At present, cold chain logistics is increasingly appearing in people's lives. Large-scale automated cold storage is the storage unit of cold chain logistics. The temperature inside the automated cold storage is usually between -10-20℃, and the equipment inside the cold storage is kept at low temperature for a long time. Stackers are installed in large-scale automated cold storage. The stackers travel between the ground rails and the ceiling rails to complete the transfer of goods in the cold storage. The stacker ceiling rails are generally made of square steel in the shape of a square U. The two upper running wheels of the stacker are clamped and travel on the left and right running treads of the square steel in the shape of a square U. During the process of loading and unloading goods from the cold storage, as the goods are transferred, the humidity inside the cold storage will suddenly change, and frost will appear on the surface of the equipment in the cold storage. As a key equipment in the automated cold storage, the stacker uses the lower track to support the upper track for positioning, and accurately transports goods in the stereoscopic warehouse. When the two treads of the stacker's overhead track are frosted, the stacker will slip during operation, resulting in problems with the stacker's positioning, causing the stacker's brake failure, and even an accident in which the stacker runs off the track. Since the temperature of the cold storage is between -10℃ and -20℃, and the stacker's overhead track is installed at an altitude of about 20 meters, it is difficult to manually defrost the stacker's overhead track in a timely manner. How to achieve automatic defrosting of the overhead track has become an urgent problem that needs to be solved in the operation of the stacker in the cold storage. Summary of the invention
