Abstract

The invention discloses an access door structure for a mill. The access door structure comprises a door frame, a door cover, a door bolt, a pin shaft, a door pivot, a compression bar and a pressing device, wherein the door frame is welded onto the outer wall of the mill; a door frame connecting hole is formed in one side of the door frame; the door pivot in clearance fit with the door frame connecting hole is arranged in the door frame connecting hole, and can rotate in the door frame connecting hole; a cotter pin for preventing the door pivot from falling is arranged at the upper end part of the door shaft; one end of the compression bar is hinged to the door frame through the door pivot; the middle part of the compression bar is connected with the door cover through the pressing device; a connecting plate is arranged on the other side of the door frame; the pin shaft is arranged on the connecting plate; a cotter pin for preventing the pin shaft from falling in the axial direction is arranged at the upper end part of the pin shaft; the door frame is connected with the door bolt through the pin shaft; the door bolt is matched with the compression bar and used for fixing the compression bar. The access door structure is simple in structure and excellent in structural closure, reduces the labor intensity of operators, and improves the working efficiency, and the door can be opened and closed conveniently.

Description

technical field [0001] The invention relates to the technical field of mill equipment, in particular to a mill maintenance door structure. Background technique [0002] Mill equipment usually needs to open various inspection holes or observation holes, and inspection doors or observation doors need to be installed at the positions of these holes, so as to ensure the sealing of the mill structure, and at the same time facilitate the observation of the operating status of the mill, and Maintenance in shutdown state. Existing inspection doors or observation doors of mills mostly adopt bolt connection structure, although the sealing requirements can be met, but this connection method has a complex structure and is inconvenient to open and close. [0003] In the mill equipment of the prior art, there are many inspection holes or observation holes in the mill structure, and door structures are usually required at the positions of these holes to ensure the sealing of the mill stru...
