Description

Technical Field

[0001] The utility model belongs to the field of logistics transportation equipment, and particularly relates to a box-type car conveyor device. Background Art

[0002] In large office buildings such as general hospitals, administrative centers, and hotels, a large amount of materials or garbage needs to be removed every day. If they are transported manually in the freight elevator, it will not only waste a lot of manpower, but also occupy the freight elevator resources and affect work efficiency.

[0003] In recent years, with the rapid development of box-type logistics transportation technology, box-type logistics has been widely adopted by medical, administrative, service and other industries due to its large load capacity and the advantages of non-self-driving design of goods. Among them, the shaft transmission mechanism in the box-type logistics system is widely used in the above-mentioned industries. The shaft transmission mechanism is divided into reciprocating type and continuous type. Among them, the reciprocating type controls the up and down reciprocating movement of the car by the hoist to realize the transportation of goods between the floors of the building. The continuous type controls the car by the hoist to continuously transport goods vertically on the floors of the building.

[0004] In the patent document with application number "CN2022210325141", a shaft-type logistics transportation system is disclosed, which transports goods by setting a track assembly with multiple tracks in the shaft, installing a diverter on the track assembly, and installing a movable lifting vehicle on the track assembly. The diverter enables the lifting vehicle to realize one-way transportation or track switching transportation in a single shaft. By using the diverter, the lifting vehicle can run at the cargo openings on different sides, and the goods can be sent and received by changing tracks in the shaft and transported across the bridge between shafts, which improves the transportation efficiency, but also correspondingly increases the cost and complexity of the system, and reduces the reliability of the system. At the same time, the lifting vehicle of the system has only a single layer, and can only perform the task of sending and receiving goods once each time it runs.
