Description

Technical Field

[0001] The utility model relates to the technical field of handling equipment, in particular to a universal transfer trolley. Background Art

[0002] A transport trolley is a commonly used transport equipment in enterprises. Its aliases include transport tanks, ground bulls, and ground tanks. Its main function is to transfer heavy objects on a flat factory floor, such as machine tools, industrial equipment, and other heavy items. This product is generally made of cold-rolled steel plates cut, processed, and welded, and then assembled with bearing rollers. It has the characteristics of strong load-bearing capacity, small size, light weight, easy use, economical and durable, etc., so it has become a necessary heavy-load transfer tool for many production and processing units. Although the transport trolley has many advantages, it has the following problems in actual use: First, the bottom of the transport trolley is usually equipped with 3 or 4 rows of parallel bearing rollers. Such an arrangement simplifies the design, reduces the difficulty of production and assembly, and can provide a larger load-bearing capacity. However, since the front and rear rows of rollers of this structure are arranged in parallel and there is no appropriate steering structure, in actual use, the steering after loading is severely restricted. In many equipment transfers, it is not conducive to the one-time transfer of the equipment into place. During use, it is usually necessary to stop and make multiple adjustments to its travel direction. Second, the transport trolley with a steering structure ignores the fact that in the actual loading process, some long and heavy objects require the cooperation of multiple trolleys to transfer. During steering, the part of the heavy object in contact with the trolley cannot be relatively moved, thus forming hard contact friction. Utility Model Content
