Anti-collision sliding door

Abstract

The invention provides an anti-collision sliding door, which is used for protecting exit and entrance channels of building enclosures. The sliding door comprises a pair of limit devices which is respectively arranged at two sides of a channel along a horizontal direction, and a door body extending along the horizontal direction; when the sliding door is opened, one end part of the door body is located in the limit device at one side; when the sliding door is closed, the two end parts of the door body are respectively located in the pair of limit devices. The sliding door is characterized in that each limit device comprises at least one pair of upright columns which extends along the longitudinal direction and is flexibly distorted when being subjected to impact force, and a foundation which is buried in the ground and extends along the direction vertical to the horizontal direction and the longitudinal direction; the pair of upright columns is respectively arranged inside and outside the door body; and the lower end parts of the pair of upright columns are respectively arranged on the foundation fixedly; and the upper ends of the pair of upright columns are separated. The limit devices adopt a pair of mutually separated upright columns, when the door is collided by violence, the impact force can be transferred to the upright columns fast, and the upright columns are flexibly distorted after being stressed so as to absorb the collision energy.

Description

technical field [0001] The invention relates to a translation door for blocking entrances and exits of building enclosures, in particular to a translation door with an anti-collision structure. Background technique [0002] Generally speaking, doors used to block the entrance passage of industrial places are usually divided into railed translation doors and trackless translation doors. The translation door includes a door body and restricting devices arranged on both sides of the entrance passage. The restricting device includes two columns and a beam connected between the two columns. The columns and beams are connected to form a frame structure. The drive motor of the door body is usually installed on one of the columns. When the translation door is opened, one side of the door body Located in one of the restricting devices, when the translation door is closed, the two sides of the door body are respectively located in the two restricting devices. At the entrance and exit...

AI Technical Summary

Problems solved by technology

At the entrance and exit of some high-security places, it is usually required that the translation door can withstand a certain impact force, such as preventing the violent invasion of land vehicles. The body leans toward one side of the column and has a rigid collision, which leads to serious deformation of the door body. After the main structure of the door body is damaged, it can only be repaired by replacing it as a whole, and the maintenance cost is high. In addition, the upper end of the column swings after being hit, resulting in Deformation of the restriction device affects the overall aesthetics
