Problems solved by technology

[0003] However, the weight of the four fire door panels in the middle is increased compared with the weight of ordinary landing doors. If the existing spring self-closing device or spring plus swing rod self-closing device is used, the self-closing force will be insufficient and the specifications of the self-closing device will be too large. unmanageable issues
At the same time, due to the complexity of the installation site, it is difficult to install the swing rod plus spring self-closing device with many parts, which may cause unnecessary injuries to the installer. For areas with high wind pressure, spring self-closing or spring plus swing rod self-closing The method often fails to adjust the self-closing force and other bad problems according to the site conditions, which seriously affects the delivery progress of the project

Abstract

The invention discloses a door body opening and closing linkage device. The back face of a first linkage support and the back face of a second linkage support are connected with a main steel wire rope in the upward direction and the downward direction correspondingly, so that a left slow door hanging plate and a right slow door hanging plate are linked, a left rapid door hanging plate and a right rapid door hanging plate are in linkage with the left slow door hanging plate and the right slow door hanging plate through a first linkage steel wire rope wheel assembly and a second linkage steel wire rope wheel assembly respectively, and therefore the four door hanging plates form a linkage structure to act together. The invention further provides a door body self-closing linkage device. Opening and self-closing of a fireproof door can be achieved, and the device can also be applied to other door bodies.

Description

technical field [0001] The invention relates to the technical field of elevator landing doors, in particular to a door body opening and closing linkage device and a door body self-closing linkage device. Background technique [0002] As the number of floors of modern buildings becomes higher and people pay more and more attention to fire safety, the demand for fire doors with larger opening sizes is increasing in the elevator market. Among them, the four fire doors in the middle can meet the market demand for elevators with larger opening sizes. [0003] However, the weight of the four fire door panels in the middle is increased compared with the weight of ordinary landing doors. If the existing spring self-closing device or spring plus swing rod self-closing device is used, the self-closing force will be insufficient and the self-closing device will have too many specifications. unmanageable issues. At the same time, due to the complexity of the installation site, it is d...
