Inspection door assembly of circular silo

Abstract

The invention discloses an inspection door assembly of a circular silo. The inspection door assembly comprises an arc-shaped door plate, an arc-shaped rotating support used for installing the door plate, an arc-shaped pressing rod used for pressing the door plate to an inspection opening of the silo, and a locking pin used for pressing and locking the pressing rod; and the radian of the door platecoincides with the arc around the inspection opening of the silo, one end of the rotating support is hinged to the position, located on one side of the silo inspection opening, of the silo, the arc-shaped inwards-concave face of the rotating support and the arc-shaped outwards-convex face of the door plate are correspondingly installed, the pressing rod and the rotating support are oppositely hinged to the position, located on the other side of the silo inspection opening, of the silo, and the locking pin is fixed on the rotating support. Operation is easy, time and labor are saved, closing is tight, and deformation is not likely to happen.

Description

technical field [0001] The invention belongs to the technical field of circular silo equipment production, and in particular relates to an inspection door assembly of a circular silo. Background technique [0002] In the prior art, the inspection door set at the inspection port of the circular silo equipment is usually connected directly to the silo by means of a hinged arc-shaped door panel. After the inspection door is closed, it is locked with a padlock. Such a structure not only cannot guarantee The door seam is tightly closed, and it is easy to cause deformation and warping of the edge of the door panel. [0003] In addition, due to the unreasonable structural design of the arc-shaped inspection door in the prior art, when the door panel is rotated and opened, the part of the door panel close to the rotating shaft used to connect with the silo often collides with the outer wall of the silo, which not only limits the The opening angle also causes damage to the door pane...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, the inspection door set at the inspection port of the circular silo equipment is usually connected directly to the silo by means of a hinged arc-shaped door panel. After the inspection door is closed, it is locked with a padlock. Such a structure not only cannot guarantee The door seam is tightly closed, and it is easy to cause deformation and warping of the edge of the door panel

[0003] In addition, due to the unreasonable structural design of the arc-shaped inspection door in the prior art, when the door panel is rotated and opened, the part of the door panel close to the rotating shaft used to connect with the silo often collides with the outer wall of the silo, which not only limits the The opening angle also causes damage to the door panel, which further affects the tight closure between the door panel and the inspection port.

[0004] Furthermore, in the inspection door in the prior art, the closing and locking mechanism adopts a handwheel structure, which causes inconvenience in operation and is time-consuming and labor-intensive.

[0005] In short, the inspection door at the inspection port of the circular silo equipment in the prior art cannot meet the needs of practical applications, so it is urgent to develop a new type of inspection door structure for the circular silo equipment
