|Title:||METHODS FOR MOUNTING AND ERECTING MECHANICAL CONSTANT-RESISTANCE SINGLE PROP|
A method for mounting a mechanical constant-resistance single prop, comprising: (1) fitting a rod body (5) within a cylinder body (3) and adjusting the fitting length according to an actual section height of a cut hole or a roadway in a mine; (2) nesting a steel ball sleeve (6) between the rod body (5) and the cylinder body (3), so that the rod body (5) presses the steel ball sleeve (6) to form self-locking; (3) fixedly connecting a limiting cover to the fitting portion of the rod body (5) and the cylinder body (3); (4) mounting and locking a top tray (4) to the upper end of the rod body (5); and (5) vertically erecting the parts of a mechanical constant-resistance single prop that are assembled in the step (4) and mounting the parts on a base. The present invention implements easy, quick and efficient mounting, and saves labor and material resources.
