Problems solved by technology
[0004] However, the transmission device in the form of motor screw nut takes up a lot of space in the thickness direction of the sliding door, which is not easy to install; and the screw nut fit requires high precision, and there is a lot of dust in the platform. If things go on like this, it is easy to affect the driving effect of the transmission device, and High maintenance cost
In addition, the half-height platform doors are easy to be climbed over by passengers, which has low safety and poor environmental protection effect on the platform

The invention relates to the technical field of rail transit platform door systems, and particularly relates to a full-height type platform door transmission device and a full-height type platform door system. The transmission device comprises a first transmission mechanism, a second transmission mechanism and a connecting frame, the first transmission mechanism comprises a driving belt wheel, a driven belt wheel and a first belt; the second transmission mechanism is used for being fixedly connected with a first sliding door and can slide in the horizontal direction relative to the first transmission mechanism, the second transmission mechanism comprises a first belt wheel, a second belt wheel and a second belt, and the interval between the first belt wheel and the second belt wheel is smaller than the interval between the driving belt wheel and the driven belt wheel; one end of the connecting frame is fixedly connected with the first belt, and the other end of the connecting frame is connected with the second belt and a second sliding door; and when the driving belt wheel rotates, the first sliding door and the second sliding door can move towards the same side and can be overlapped, the net opening degree of the sliding door is increased, the structure is simple, the occupied space is small, and installation and follow-up maintenance are convenient.
Description
technical field [0001] The invention relates to the technical field of rail transit platform door systems, in particular to a full-height platform door transmission device and a full-height platform door system. Background technique [0002] The platform door system usually includes a fixed door, a sliding door and a transmission device. When a vehicle enters the platform and the vehicle door corresponds to the sliding door, the transmission device drives the sliding door to open for passengers to get on and off. At present, most of the sliding doors of the platform door system adopt the form of double doors, and the sliding doors are hidden behind the fixed doors adjacent to the sliding doors after being opened. The net opening of this type of sliding door is related to the width of the fixed door. When the size of the fixed door is limited, the net opening of the sliding door will also be limited, which cannot meet the large opening requirements of the platform door system...
