Abstract

A novel landing door structure of a high-speed elevator and a maintenance method therefor. The novel landing door structure of the high-speed elevator comprises an installation panel (1) and two door panels (2). The installation panel (1) is located above the door panels (2); a fixing block (3) is fixedly installed on the outer wall on one side of a front face of the installation panel (1); a sliding rail (4) is fixedly installed inside the fixing block (3) and runs through the fixing block (3); first supporting blocks (5) fixedly installed on the outer wall of the installation panel are arranged on the left side and the right side of the sliding rail (4); a fixing rod (6) is fixedly installed inside each first supporting block (5); an adjusting groove (7) is formed in each fixing rod (6); an adjusting rod (8) is movably installed inside each adjusting groove (7); and springs (9) are connected between one end of the adjusting rods (8) and the inner walls of the adjusting grooves (7). By means of the described configuration, a transmission mechanism can be stable and simple, the occupied space is small, and the cost is reduced. A bearing mechanism is convenient to replace and maintain, and only a bushing needs to be replaced, which saves resources.
