Description
Technical Field
[0001] The utility model relates to the technical field of cargo loading and unloading, in particular to a vehicle-mounted cargo unloading device. Background Art
[0002] In the current logistics and transportation industry, ordinary transport vehicles generally lack automated and efficient cargo loading and unloading equipment, resulting in loading and unloading operations mainly relying on manpower or external mechanical devices such as loaders. However, both methods face significant limitations. Although manual loading and unloading is flexible and convenient, it consumes a lot of labor resources, is inefficient, and is prone to cargo damage. Its economic efficiency decreases with rising labor costs. Although external mechanical devices can improve efficiency, the high cost, complex operation, limitations in loading and unloading of high-precision and fragile goods, and the need for additional site equipment all increase the complexity and overall cost of loading and unloading operations, limiting the efficiency and cost-effectiveness of logistics and transportation.
[0003] Although there are already some vehicle-mounted cargo loading and unloading devices on the market, these devices still have many shortcomings in actual application. First, many existing devices cannot flexibly move left and right and forward and backward when transporting cargo inside the vehicle compartment, which seriously limits the efficiency of loading and unloading operations. In complex and changeable loading and unloading scenarios, this limitation often leads to extended operation time and increased costs; second, some vehicle-mounted loading and unloading devices have complex structures and occupy a large space, which is not conducive to maximizing the loading capacity of transport vehicles.
[0004] Chinese patent document CN202480950U discloses a vehicle-mounted cargo loading and unloading device, comprising an inverted U-shaped guide rail bracket fixed to the carriage frame, a guide rail fixedly mounted on the guide rail bracket extending at least to the rear end of the carriage, a cargo hoisting device for loading and unloading cargo slidably mounted on the guide rail, and sliding limit devices provided at both ends of the guide rail. However, the following defects still exist during implementation:
[0005] Although the device in the above-mentioned document can use the change in the position of the cargo lifting device on the guide rail to drive the movement of the cargo and place the cargo at a designated location in the transport carriage, the device in the above-mentioned document uses an inverted "U"-shaped guide rail bracket. Such a guide rail bracket makes it impossible for the device to flexibly move left and right and forward and backward when transporting cargo inside the carriage, which seriously limits the efficiency of loading and unloading operations. In complex and changeable loading and unloading scenarios, this limitation often leads to extended operation time and increased costs. Utility Model Content
