Description

Technical Field

[0001] The utility model relates to the technical field of truss accessories, in particular to a guide wheel mechanism of a truss guide rail beam. Background Art

[0002] A truss is a supporting beam structure formed by connecting rods at both ends with hinges through welding, riveting or bolts. The advantage of a truss is that the rods mainly bear tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials, reduce deadweight and increase rigidity compared to a solid beam. The truss is equipped with a guide beam and a guide mechanism.

[0003] In the Chinese patent with publication number CN219159438U, an adaptive guide wheel for a truss guide beam is mentioned. A rocker arm is hinged with a shock-absorbing rubber pad and an axle frame so that the roller can adapt when it contacts the rough surface of the outer surface of the guide beam. The shock-absorbing rubber pad can provide a certain flexible support for the assembly plate, and the rollers on both sides of the rocker arm can swing adaptively when walking on the rough surface of the outer surface of the guide beam; however, when the guide mechanism is in use, the length of the guide mechanism is fixed and can only be guided on two guide beams with a fixed spacing, and cannot be used for two guide beams with different spacings, which reduces the scope of application of the guide mechanism and also reduces the practicality. Therefore, we introduce a guide wheel mechanism for a truss guide beam. Utility Model Content
