[0007] The connection between the hanging wheel 6 and the door guide rail 2 depends on the cooperation between the wheel groove of the hanging wheel 6 and the slide rail of the door guide rail 2. If the strength of the door hanging plates 3 and 24 is poor, under a large impact force, the upward pressure The gap between the roller 7 and the bottom surface of the door guide rail 2 will increase with the deformation of the door hanging plates 3, 24, and the clamping of the door guide rail 2 cannot be realized. At this time, the door hanging plates 3, 24 will leave the door guide rail with the door panels 2. Eventually there will be a risk of passengers falling down the shaft

The invention discloses an elevator lading door mechanism. The mechanism comprises an upper ridge rack body, a door guide rail, an active door board, a passive door board, a rope returning wheel assembly and a steel wire rope; the active door board and the passive door board are arranged on the door guide rail which is in fixed connection with the upper ridge rack body, the active door board and the passive door board are respectively connected with the steel wire rope through steel wire rope clamps, respectively connected with the door guide rail through a change gear and respectively connected with the bottom of the door guide rail through an upper pressure roller, the bottom of the door guide rail is provided with baffle plates that are arranged between the upper pressure roller and door boards, and gaps are provided between the baffle plates and the upper pressure roller as well as the door boards. According to the invention, baffle plates are provided between the upper pressure roller and the door boards so as to limit and protect the upper pressure roller in a horizontal direction, which enables the door boards not to leave the door guide rail when the door boards suffer from great impact, thereby substantially improving safety performance and ensuring safety of passengers.
Description
technical field [0001] The invention relates to an elevator, in particular to an elevator hall door device. Background technique [0002] When the elevator arrives at the landing, the car door machine drives the landing door device of the elevator, and the landing door device of the elevator drives the landing door panel to open and close the landing door for passengers to enter and exit. [0003] Such as figure 1 As shown, the elevator landing door device is mainly composed of upper sill body 1, door guide rail 2, door hanging plate assembly, rope return wheel assembly 4, steel wire rope 23, door lock switch, etc. The door hanging plate assembly includes The active door hanging plate 3 and the passive door hanging plate 24, the door guide rail 2 are fixedly connected with the upper sill body 1; the active door hanging plate 3 and the passive door hanging plate 24 are respectively equipped with wire rope clips 26, 25; Plates 3 and 24 are respectively connected to steel wir...
