Wide channel scissor door device

Abstract

The invention discloses a wide-channel shear type door leaf device which comprises a rack, a door leaf and a driving mechanism. The door leaf comprises an outer door plank and an inner door plank. The driving mechanism comprises a power output mechanism, a first connecting rod assembly comprising a first connecting rod and a second connecting rod, and a second connecting rod assembly comprising a third connecting rod, a fourth connecting rod and a fifth connecting rod. One end of the first connecting rod is in transmission connection with the power output mechanism, and the power output mechanism is used for driving the first connecting rod to rotate. The other end of the first connecting rod is connected to one end of the second connecting rod in a pivotal manner, and the other end of the second connecting rod is connected to the outer door plank in a pivotal manner. The middle portion of the fourth connecting rod is connected to the outer door plank in a pivotal manner, one end of the fourth connecting rod is connected to one end of the third connecting rod in a pivotal manner, and the other end of the third connecting rod is connected to the inner door plank in a pivotal manner. The other end of the fourth connecting rod is connected to the fifth connecting rod in a pivotal manner, and the other end of the fifth connecting rod is connected to the rack in a pivotal manner. The wide-channel shear type door leaf device further comprises a guiding mechanism. According to the wide-channel shear type door leaf device, opening and closing of the door leaf can be more stable, and the failure rate is lowered.

Description

technical field [0001] The present invention relates to wide aisle scissor door devices. Background technique [0002] The wide channel scissor door device is a device used to control the rapid entry and exit of pedestrians. It can be applied not only to the rail transit industry, but also to some comprehensive entertainment venues, large halls and high-end business industries. The door device includes a fixed frame With the fan door, due to the wide part of the passage, the general fan door device adopts the fan door including the inner door panel and the outer door panel, while the existing wide channel scissors type door is in the process of opening and closing due to the way of gear transmission. The opening of the door produces a large momentum, and the door only adopts a hinged connection method, which causes a large vibration and shaking when the door is opened and closed, which leads to a high failure rate. Contents of the invention [0003] In order to overcome t...
