Description

Technical Field

[0001] The utility model belongs to the technical field of production of assembled building components, and in particular relates to an anti-derailment structure for a steel trolley of an assembly line. Background Art

[0002] In the current assembly line of prefabricated concrete components, the mobile work platform plays a vital role. This platform usually adopts a flat steel platform with a length and width of 3*5 meters, which is called "steel trolley" by industry insiders. Two rows of parallel steel rollers are arranged under the steel trolley, and the rollers constitute a forward track, providing a smooth movement of the steel trolley. The outer extension of the inner protrusion of the steel roller is closely matched with the bottom of the steel trolley. This precise match enables the steel trolley to move stably in the straight track formed by the two rows of rollers. However, during use, due to the continuous friction between the steel trolley and the roller, wear and tear inevitably occurs. This wear and tear gradually accumulates, and sometimes causes the steel trolley to gradually break away from the restriction of the steel roller and derail. Once derailment occurs, the consequences are disastrous. Therefore, the utility model provides a steel trolley anti-derail structure, which makes the steel trolley body be restricted by the bearing during the forward process, corrects the track, reduces wear, and thus achieves the purpose of anti-derailment.

[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
