Segmentation-formed escalator cover plate

Abstract

The invention relates to a segmentation-formed escalator cover plate. The segmentation-formed escalator cover plate is characterized in that the escalator cover plate comprises an upper transition connecting plate, an arc intermediate plate and a lower transition connecting plate which are sequentially connected and formed integrally; observed from the cross section direction of the escalator cover plate, the escalator cover plate comprises an outer side arc plate, a bottom face connecting plate, a bottom face bending plate, a top face connecting plate and a top face bending plate; and the lower end of the bottom face bending plate is connected with the right end of the bottom face connecting plate, the bottom face bending plate and the bottom face connecting plate are kept perpendicular and extend upwards in the vertical direction, the upper end of the top face bending plate is connected with the right end of the top face connecting plate, the top face bending plate and the top face connecting plate are kept perpendicular and extend downwards in the vertical direction, and the downward extending length of the top face bending plate in the vertical direction is smaller than the upward extending length of the bottom face bending plate in the vertical direction. The defects of plate extruding, cracking, deforming and the like possibly caused by sudden changing of the strength inthe process that a plate body is directly formed from a flat state into an arc curve are avoided, and the stability of the reversing and forming process and the balance strength of the formed plate body are ensured.

Description

technical field [0001] The invention relates to a plate material, in particular to a section-formed escalator cover plate. Background technique [0002] The turning end of the handrail is a reusable organizational part of the escalator. During the operation of the handrail, the resistance mainly comes from the place where the handrail is matched. The most likely place to cause frictional resistance is the cover part of the steering end of the handrail. The wear degree of this part is the worst. Circular curve design, the design and forming process is complex and difficult, and due to the lack of design of the front and rear transition sections in the forming process of the circular arc curve, it is directly designed as a circular arc curve, which is neither convenient for the installation and fixing of the escalator cover plate, nor It is conducive to the balanced transition of the strength of the escalator board from the original flat state to the arc curve, and it is easy...

Circular curve design, the design and forming process is complex and difficult, and due to the lack of design of the front and rear transition sections in the forming process of the circular arc curve, it is directly designed as a circular arc curve, which is neither convenient for the installation and fixing of the escalator cover plate, nor It is conducive to the balanced transition of the strength of the escalator board from the original flat state to the arc curve, and it is easy to cause a sudden change in the internal strength of the board, resulting in defects such as extrusion, cracking, and deformation of the board.
