Description
[technical field]
The utility model relates to stainless steel antiskid pedal, belongs to elevator and makes field, particularly a kind of corrosion-resistant steel pedal with new-type antiskid groove that is used for stair step and moving sidewalk.
[background technology]
Transmit the passenger for convenience, in the heavy constructions such as airport, market, office building staircase or moving sidewalk can be installed, the pedal of trampling for the passenger all is installed on it.Existing corrosion-resistant steel pedal comprises the corrugated plating with some parallel contour convex tendons and is connected in the crossbeam of corrugated plating below that the supporting part at convex tendon top forms the zone of trampling for the passenger substantially at grade.In order to ensure passenger safety, improve the antiskid capability of pedal, the supporting part of each convex tendon is equipped with a plurality of anti-slip tanks.In the prior art, anti-slip tank is removed the part metals material by directly slotting at supporting part and is formed, this order is left the convex tendon supporting part thickness attenuation at anti-slip tank place and is caused damaged metal, make the more original metallic material of mechanical strength of supporting part obviously reduce, the pedal antiskid capability with this anti-slip tank is relatively poor.Also have a kind of stainless steel antiskid pedal that utilizes mould to suppress anti-slip tank, promptly utilize mould to make the metallic material of the supporting part formation anti-slip tank that deforms by exerting pressure.Specifically at least one convex tendon is nested with roughly suitable with its length, driving surface is on the bed die on plane, press down with convex tendon top and with mold that bed die is used then, double wedge on the mold driving surface is pressed in the metallic material of supporting part, and force the metallic material of double wedge extruding place to move towards periphery, it is inner concave that double wedge extruding place promptly forms upper surface, lower surface is the anti-slip tank on plane, more preceding a kind of the increasing of mechanical strength with corrosion-resistant steel pedal of this anti-slip tank, but the supporting part between adjacent anti-slip tank thickens because of moving of metallic material, and the supporting part at anti-slip tank place pushes the thickness attenuation because of the mold double wedge, and its mechanical strength still can not reach promising result.In addition, the cup depth of above-mentioned two kinds of anti-slip tanks must be much smaller than the original thickness of supporting part metallic material, and therefore, more shallow anti-slip tank skidproof effect is undesirable.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the defective that present technology exists, and the corrosion-resistant steel pedal that a kind of mechanical strength and antiskid capability are all comparatively desirable, have the new-type antiskid groove is provided.For this reason, the utility model adopts following technical scheme:
Corrosion-resistant steel pedal with new-type antiskid groove, comprise corrugated plating and be connected the crossbeam of corrugated plating bottom surface perpendicular to the convex tendon bearing of trend with a plurality of parallel and equidistant convex tendons, described convex tendon comprises the supporting part at top and the sidewall that the supporting part both sides are bent to form downwards, the sidewall of adjacent two convex tendons is bent into a groove in opposite directions, described supporting part is provided with a plurality of anti-slip tanks that caves in, and the upper and lower surface that it is characterized in that described anti-slip tank all is depressed in supporting part and shape is identical.On the anti-slip tank, lower surface is the end face of the relative supporting part of difference, the curved surface and the shape that arch upward downwards in the bottom surface are identical, ultimate range between the bottom surface of the ultimate range of the end face of described upper surface and supporting part and described lower surface and supporting part is consistent, that is to say, the anti-slip tank of this structure is to make on it during fabrication, lower surface is respectively with respect to the end face of supporting part, the bottom surface is caved in mobile simultaneously, and the distance that both move is consistent, this just makes the thickness of anti-slip tank place metallic material before caving in, after almost do not change, the thickness of other part metals materials of supporting part is only because of the anti-slip tank generation subtle change of caving in, the metallic material that anti-slip tank place supporting part is set did not both reduce because of cutting, be not extruded yet be diffused into around, reduced most possibly owing to the damaged metal that anti-slip tank causes supporting part is set, convex tendon and the original mechanical strength of supporting part metallic material thereof have been kept well, thereby make pedal have comparatively desirable mechanical strength, meanwhile, because the anti-slip tank of this structure is little to the damage of supporting part, its degree of depth of caving in also can significantly increase than the anti-slip tank of existing structure, obviously increased the friction coefficient of supporting part, make the antiskid capability of supporting part outstanding, better guarantee passenger's safety.
For the improving and replenishing of technique scheme, can increase following technical characterictic:
The end face of supporting part is the plane between described adjacent two anti-slip tanks.Such structure makes and the supporting part height convergence unanimity of each bar convex tendon on the pedal forms good carrying surface, increases the area of contact of passenger when trampling, and helps to improve antiskid capability.
The upper and lower surface of described anti-slip tank is arc surface, and the ultimate range between the bottom surface of the distance between upper and lower surface and the ultimate range of the end face of described upper surface and supporting part, described lower surface and supporting part equates.At this moment, the ultimate range between the end face of supporting part and the lower surface of anti-slip tank equals the distance between 2 times the upper and lower surface of anti-slip tank, and the mechanical strength of supporting part and skidproof effect reach the optimum balance value.
Anti-slip tank of the present utility model is than the advantage of prior art: on it, lower surface simultaneously, even depth is caved in, reduced as much as possible because the damaged metal that anti-slip tank causes to supporting part is set, convex tendon and the original mechanical strength of supporting part metallic material thereof have been kept well, the anti-slip tank degree of caving in is not subject to the thickness of supporting part metallic material, its degree of depth of caving in also can significantly increase than the anti-slip tank of existing structure, effectively increase the friction coefficient of supporting part, skidproof effect is outstanding, thereby make corrosion-resistant steel pedal mechanical strength comparatively desirable, good antiskid effect with this spline structure anti-slip tank.
