Description

Technical Field

[0001] The utility model relates to the technical field of a four-car group trolley, in particular to a four-car group trolley. Background Art

[0002] Hangers are commonly used tools in industrial production for hanging and moving objects. In production lines, warehouses and other places, the demand for the transportation of hangers is increasing. Traditional methods of transporting hangers usually use manual handling or simple mechanical handling, which is not only inefficient but also easy to damage the hangers. Therefore, in the process of transporting friction bar suspension chain hangers, two-car trolleys are usually used to move them. At present, the existing two-car trolleys of friction bar suspension chains can only carry about 200 kilograms of products, and the friction provided cannot drive heavier products, which increases the limitations of the use of the trolleys. In addition, the convenience of automatic accumulation of the trolleys is poor. When the length of the trolley increases, interference is prone to occur during turning, thus limiting the length of a single car of the two-car trolley, which is not convenient to meet the use requirements.

The connecting trolley, the front trolley and the rear trolley move, so that the connecting trolley, the front trolley and the rear trolley move and transport the hanger. When the contact devices contact each other, they rotate and move, and the power of the rotational movement drives multiple groups of friction trolleys to move downward, so that the multiple groups of friction trolleys are separated from the external friction rod, and the accumulation of the four-car group trolleys is realized, which increases the load-bearing effect on the hanger.
