Sliding door of factory building

Abstract

The invention discloses a sliding door of a factory building, which comprises an upper beam, a lower guide rail and a door leaf. The door leaf consists of a door body, more than two rollers below the door body and more than two moving parts above the door body; each moving part consists of a bearing piece, two bearings and a bearing connecting piece for connecting the bearing piece and the top end of the door body; two ends of the bearing piece are provided with mounting bearing sections; the two bearings are fixed on the mounting bearing sections of the bearing piece respectively. The sliding door of the factory building adopts the structure, so that the weight of the door leaf is born by an upper beam, the push-pull force of the door leaf is reduced and the push and pull are light; and even if wagons passes the factory building to cause the slight deformation of the lower rail, the verticality of the door leaf can stay the same for a long time, and the tightness of the sliding door can be ensured.

Description

Technical field [0001] The invention relates to a building workshop, in particular to a sliding door of a building workshop. Background technique [0002] At present, the sliding door of the construction workshop includes an upper beam, a lower guide rail and a door leaf. The door leaf is composed of two or more rollers under the door body rolling along the lower guide rail, the door body and the moving parts that move along the upper beam. The moving part is one The structure plays a guiding role. The weight of the door is supported by rollers. The rollers roll back and forth in the lower rail. When the door leaf is opened, trucks and trucks often pass by the lower rail. The lower rail will be slightly deformed, not only sliding the door leaf. The strength is large, and the verticality of the door leaf changes after a period of use, which causes the door to not close tightly, and the wind and rain can enter the plant. Summary of the invention [0003] The technical problem to b...

[0002] At present, the sliding door of the building workshop includes an upper beam, a lower guide rail and a door leaf. The door leaf is composed of more than two rollers below the door body that roll along the lower guide rail, the door body and a moving part that moves along the upper beam. The moving part is a As a guiding structure, the weight of the door is all supported by the rollers, which roll back and forth in the lower guide rail. When the door leaf is opened, trucks and load-carrying trolleys often pass by the lower guide rail, and the lower guide rail will be slightly deformed. The strength is relatively large, and the verticality of the door leaf changes after a period of use, resulting in the door not being tightly closed, and wind and rain can enter the factory building
