The contact parts on the upper and lower sides of the horizontal laying rail 101 with the mounting plate 102 are both hook - edge structures, ensuring that the mounting plate 102 can be wrapped inside the horizontal laying rail 101. The flat head square neck bolt 104 passes through the horizontal wheel rail 103 and the horizontal laying rail 101, and the free end of the flat head square neck bolt 104 is locked and fixed by a nut.

[0030] As Figures 1 - 2 shown in the figure, in this embodiment, the upper and lower sides of the horizontal wheel rail 103 facing away from the horizontal laying rail 101 are both hook - edge structures, which can ensure the reliable sliding of the self - contained rollers on the industrial lifting door. The external hexagon flange bolt 202 passes through the perforated angle steel 201 and the mounting plate 102, and the free end of the external hexagon flange bolt 202 is locked and fixed by a nut, ensuring that the external hexagon flange bolt 202 can be reliably locked after installation. The perforated angle steel 201 is also provided with mounting holes connected to the industrial lifting door, which can realize the reliable connection between the industrial lifting door and the perforated angle steel 201.
