Step walking trolley

Abstract

The invention relates to a goods transfer device, in particular to a step walking trolley. The step walking trolley comprises a frame and walking wheels. The walking wheels comprise at least two pairs of foldable trundles and at least one pair of height-fixed trundles, wherein the foldable trundles are assembled on the frame through foldable wheel frames, and the height-fixed trundles are located on the front portion of the frame. The foldable wheel frames are assembled on the frame through hinged shafts in a hinged mode. The axis of each hinged shaft is parallel to the axis of each walking wheel. An excessive-rotation-resistant structure, a resting mechanism and a locking structure are arranged between the frame and each foldable wheel frame, wherein the excessive-rotation-resistant structure is used for preventing the foldable wheel frame from rotating forwards, the resetting mechanism is used for driving the foldable wheel frame to restore an unfolded state automatically, and the locking structure is used for locking the foldable wheel frame into the unfolded state. By the adoption of the step walking trolley, on one hand, a slope does not need to be erected any more and goods can be delivered upwards and downwards in a horizontal state; on the other hand, carrying transferring of the goods is not needed, and therefore the working efficiency of transferring the goods between places with different heights can be improved.

Description

technical field [0001] The invention relates to cargo transfer equipment, in particular to a ladder walking trolley. Background technique [0002] In some continuous production lines, or in the process of loading and unloading goods, it is often necessary to transfer goods between stepped platforms of unequal heights. In the prior art, the transfer of goods between platforms of unequal heights is carried out by ordinary flat trolleys. Yes, in order to provide a walking path for flat trolleys, slopes are usually set between two adjacent platforms, and sometimes it is even necessary to transfer goods by manual handling. [0003] However, when loading and unloading valuable and fragile goods to vehicles, if there is no loading platform at the same height as the vehicle compartment at the loading site, the goods must be loaded and unloaded through the above-mentioned slope or manual handling, which not only requires high work intensity but also low loading and unloading efficien...

Problems solved by technology

[0003] However, when loading and unloading valuable and fragile goods to vehicles, if there is no loading platform at the same height as the vehicle compartment at the loading site, the goods must be loaded and unloaded through the above-mentioned slope or manual handling, which not only requires high work intensity but also low loading and unloading efficiency. It is a waste of manpower and material resources, and it will cause damage to the goods due to factors such as vibration during shipment
