DETAILED DESCRIPTION
[0020] The present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.
[0021] The specific implementation process of the utility model is as follows:
[0022] like Figures 1 to 3 As shown, the staircase track changing device includes a transmission slide rail, a special-shaped structural plate and a man-carrying device. The special-shaped structural plate is arranged close to the top plate of each stair turning platform. The four corners of the special-shaped structural plate are supported and fixed by columns close to the wall to ensure that the special-shaped structural plate is stable and immovable. The transmission slide rail is fixed on the special-shaped structural plate, and the man-carrying device is slidably connected to the transmission slide rail. The man-carrying device can slide on the transmission slide rail to carry people up and down the stairs. The transmission slide rail includes a connecting slide rail, a movable slide rail and a fixed slide rail. The connecting slide rail is located below the top of the stairs. The fixed slide rail is located directly below the turning platform and is arranged in two sections in parallel. The movable slide rail is located between the connecting slide rail and the fixed slide rail. A slide rail driving mechanism is arranged on the special-shaped structural plate opposite to the movable slide rail. The slide rail driving mechanism is connected to the movable slide rail driving to drive the movable slide rail to rotate so that one end of the movable slide rail abuts against the connecting slide rail and the other end abuts against any section of the fixed slide rail. Specifically, by arranging two sets of man-carrying devices on the transmission rail, two people can go up and down the stairs at the same time by riding the man-carrying device. The fixed slide rail on the turning platform is set into two sections, and the movable slide rail used for connecting the fixed slide rail and the connecting slide rail at the turning point of each staircase is designed to be movable. The movable slide rail is driven to rotate by the slide rail driving mechanism fixed on the special-shaped structural plate, so that the movable slide rail can realize the connection between the connecting slide rail and any section of the fixed slide rail. When two manned devices running simultaneously on the transmission slide rail are in the going upstairs and going downstairs states respectively, staggered giving way can be achieved at the turning point of each staircase.
[0023] There are multiple groups of transmission rails, which are respectively arranged at the top of the turning platform of each staircase. The fixed rails on each group of transmission rails are connected to the connecting rails of the adjacent group through movable rails, so that the transmission rails are continuously laid from the bottom of the staircase to the top floor platform. The manned device can smoothly move back and forth from the bottom to the top floor along the transmission rails.
[0024] In an embodiment of the utility model, a rack with teeth facing downward is provided below the transmission slide rail, a sliding fixture is slidably connected to the transmission slide rail, a motor and a gear are fixedly provided on the sliding fixture, the motor is fixedly connected to the gear, and the gear is meshed with the rack. Specifically, the sliding fixture is suspended on the transmission slide rail, the motor and the gear are arranged inside the sliding fixture, and when the motor rotates, the gear meshes with the rack, thereby driving the sliding fixture to slide along the transmission slide rail.
[0025] In an embodiment of the utility model, a man-carrying device is arranged on a sliding fixture, and the man-carrying device includes a movable disc, a suspension rod and a seat. The movable disc is arranged on one side of the sliding fixture, and two suspension rods are arranged. The top ends of the two suspension rods are fixed on the movable disc, and the bottom ends of the two suspension rods are connected to the seat. Specifically, the movable disc can rotate freely, and is not affected by the inclination of the sliding fixture when going up and down stairs, so that the suspension rod and the seat fixed on the movable disc are always kept in a horizontal state, ensuring the safety and comfort of passengers. The suspension rod is not only used to connect the seat, but also can be used as a backrest of the seat. The seat includes a seat plate and a seat plate support rod. The seat plate is hingedly connected to the suspension rod and is perpendicular to the suspension rod. One end of the seat plate support rod is hinged to the bottom surface of the seat plate, and the other end of the bottom plate support rod is hinged to the bottom of the suspension rod. When the seat plate is placed horizontally, the seat plate is perpendicular to the suspension rod, and the seat plate support rod plays a role in supporting the seat plate to ensure the stability of the seat plate; when no one is sitting, the seat plate can be folded and retracted, leaning on the suspension rod, reducing the impact on residents walking up and down the stairs.
[0026] In an embodiment of the utility model, the passenger carrier also includes a movable pressure rod, both ends of which are hinged on the suspension rod. When a person sits down, the movable pressure rod can be lowered and pressed on the shoulders and chest of the human body, thereby effectively limiting the passenger's range of movement and ensuring people's safety when going up and down stairs in the passenger carrier.
[0027] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
