Detailed Description
The invention will be further described with reference to the accompanying drawings, which are provided for illustration of specific embodiments of the invention and are not to be construed as in any way limiting the invention, as follows:
the free lifting caster for the lifting machine comprises a frame 1, a caster 3, a caster shaft 4, a rotating frame 2, a rotating shaft 5 and an adjusting component;
the rotating frame 2 is rotationally fixed on the rack 1 through a rotating shaft 5;
the caster wheel 3 is rotationally fixed on the rotating frame 2;
the first end of the adjusting component is connected with the frame 1; the second end of the adjusting component is connected with the rotating frame 2; the distance between the first end and the second end of the adjusting component can be adjusted; the first end of the adjustment member, the second end of the adjustment member and the center of the rotation shaft 5 are not collinear.
Specifically, as shown in fig. 1, the free lift caster for a lift includes a frame 1, a rotating frame 2, a caster 3, a caster shaft 4, a rotating shaft 5, an adjusting shaft 6, an adjusting frame 7, and an adjusting bolt 8. The rotating frame 2 is of a groove-shaped structure with a downward opening. The rotating shaft 5 penetrates through the side surface of the rotating frame 2, is arranged perpendicular to the rack 1, and is used for rotatably fixing the rotating frame 2 on the rack 1 so that the rotating frame 2 can freely rotate around the rotating shaft 5. The caster 3 is rotatably fixed on the rotating frame 2 through a caster shaft 4, so that the caster 3 can freely rotate around the caster shaft 4 and can synchronously rotate with the rotating frame 2.
In some embodiments, the rotating frame 2 may be a plate-like structure disposed perpendicular to the rotation axis 5. The caster shafts 4 are arranged perpendicular to the rotating frame 2. The adjusting shaft 6 is fixed on the side surface of the rotating frame 2.
As shown in fig. 2, the adjusting frame 7 is fixed on the frame 1, and the fixing manner may be a fixing form capable of preventing the adjusting frame 7 from moving relative to the frame 1, such as bolt fixing, rivet fixing, and welding fixing. In some embodiments, the adjustment frame 7 and the frame 1 may be integrally formed. The adjusting bracket 7 has an adjusting bracket hole (not shown) for engaging with the adjusting bolt 8. The adjusting bracket hole of the adjusting bracket 7 is a threaded hole matched with the adjusting bolt 8.
