Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1 to 4, the utility model discloses an effectively improve an embodiment of escalator access & exit floor cold-formed steel safe in utilization, including all frames 1 and apron 2, all the frames are fixed to be set up on staircase truss 3, and the apron setting is in all the frames, and all the frames are special-shaped cold-formed structure, can prepare comparatively complicated cross-section to overall structure intensity is high, size precision is high. Specifically, the special-shaped cold bending structure comprises an n-shaped isolation convex part 4, a groove-shaped limiting concave part 5 is arranged on one side of the n-shaped isolation convex part, the bottom edge of the n-shaped isolation convex part is connected with the top edge of the groove-shaped limiting concave part through a supporting platform 6, the other top edge of the groove-shaped limiting concave part is connected with a horizontal outer platform 7, the n-shaped isolation convex part is positioned above the supporting platform on the basis of the supporting platform, the groove-shaped limiting concave part is positioned below the supporting platform, the height of the horizontal outer platform is not more than that of the supporting platform, and the bottom of a cover plate is directly erected on the supporting platform to form support; the horizontal limiting plates 8 are arranged on the side edges, corresponding to the walking direction, of the bottom of the cover plate, the vertical limiting plates 9 are arranged on the side edges, corresponding to the walking direction, of the bottom of the cover plate, the two vertical limiting plates are inserted into the groove-shaped limiting concave parts, when the cover plate inclines in the positions of the two sides, the vertical limiting plates incline synchronously, the inclined vertical limiting plates can interfere with the inner walls of the groove-shaped limiting concave parts, and therefore the purpose of inhibiting the inclination from forming overturning and collapsing is achieved, the movement amount of the cover plate in the direction is greatly limited, one side, located in the walking direction, of the cover plate is matched with the horizontal outer platform through the horizontal limiting plates, the side position of the cover plate cannot move upwards, and the inclined overturning movement of the cover plate in the direction can be limited; the cooperation of both restrictions has realized that the apron still has good stability in use under for the lock solid or not hard up problem, tramples and can not overturn, safe and reliable. When the apron is assembled, align the spacing concave part of cell type with vertical limiting plate earlier to insert from last to down, set up on supporting platform until the apron, promote the apron afterwards, make the outer platform of level stretch into horizontal limiting plate below and can accomplish the assembly, carry out the matching installation of components such as lock solid or comb plate afterwards.

Still be provided with horizontal inner platform 10 between spacing concave part of cell type and the outer platform of level, can improve the intensity of the outer platform of level to the horizontal inner platform can reduce the notch size of the spacing concave part of cell type, reduces the clearance of vertical limiting plate, avoids leading to the spacing concave part of cell type to influence the restriction effect greatly because of the restriction of bending. The supporting platform is fixed with the escalator truss through the bolt assembly, and operation is convenient. An extension edge 11 is arranged on the other bottom edge of the n-type isolation convex part and is used for extending into the lower part of the building floor, so that the fixing effect of the peripheral frame can be enhanced; and in the narrow and small gap between two adjacent week frames, can also play the effect of supporting fixed building floor, make things convenient for the construction of this position.

Because the factors of the treading accidents in the treading process are many, the reinforcing cross bar 12 is further arranged in the peripheral frame, and as shown in fig. 5 and 6, the reinforcing cross bar can further ensure the use stability of the cover plate. Specifically, consolidate the horizontal pole and be the channel-section steel structure, thickness is little, and intensity is higher than panel, makes things convenient for the clod wash preparation, consolidates the horizontal pole both ends and is provided with jam plate 13, and the jam plate is connected with all frame locks, and the jam plate is for consolidating partly of horizontal pole and through bending formation. In order to facilitate disassembly and assembly, the locking plate is inserted into the groove-shaped limiting concave part, the surface of the locking plate is welded with a rear screw 14, a nut 15 is arranged on the screw, an avoiding opening 16 is arranged on the side wall of the groove-shaped limiting concave part corresponding to the screw, and the nut and the locking plate are matched and clamped and fixed on the groove-shaped limiting concave part at the periphery of the avoiding opening. When the locking plate is used, the locking plate can be fixed or not only by loosening or screwing the nut, the operation is convenient, and the nut cannot fall into the equipment due to misoperation, so that the locking plate is safe and reliable. The peripheral frame corresponding to the reinforcing cross rod is provided with an avoiding part 17 for sinking the reinforcing cross rod and avoiding the interference with the bottom height of the cover plate.

In an embodiment, refer to fig. 7 and 8 and show, because the setting of horizontal limiting plate and vertical limiting plate, the apron structure is fit for adopting frame construction, frame construction's top sets up decoration panel 112, the horizontal limiting plate and the vertical limiting plate of bottom can regard as the rib, through bending to the apron side with the decoration panel bend the portion cooperation welding together, overall structure's intensity can be effectively improved, and the maintenance in-process that causes collide with and also can not cause the side turn-up scheduling problem, improve the service quality.
