Abstract
The utility model relates to an elevator-door floor ridge, comprising a stainless steel floor-ridge body. At least one guide groove matching the guide block of the elevator is bent at one end of the floor-ridge body; the guide groove extends toward the direction in which the guide block moves along the guide groove; the stainless steel plate is t thick; the guide groove is b wide, and the groove width b is not smaller than 5 times of the thickness t; the guide groove is h deep, and the groove depth h is not greater than 1.7 times of the groove width b. Because the floor-ridge adopts stainless steel plates, the appearance is nice and elegant, the surface is rigid and wearable; besides, an elevator floor-ridge structure with a simple cross-section shape and applicable to warp processing is designed to settle the problem that the complicate moulding surface can not be easily achieved by stainless steel plate bending technology; the manufacturing process is simplified by warp moulding; the manufacturing process does not need any mould, and as a result, the production cost is reduced and relatively high use value is achieved.
Description
Technical field
The utility model relates to a kind of lift cabin door sill, is a kind of be used to support come in and go out passenger's the weight of lift car and car assembly that the switch door of gate, layer door is play the guiding role.
Background technology
In the existing technical field, the gangway of lift car and hoistway is provided with the fall sufficient point of sill as elevator passenger discrepancy car usually, and sill is again the guide track of elevator cab door, hoistway layer every plate simultaneously.Usually sill is provided with guide groove, and the door-plate bottom is provided with orienting lug, and described orienting lug is plugged in the described guide groove and folding under the guiding of guide groove, thereby guarantees the safe operation of door-plate.
The sill of traditional lift car has two kinds of forms usually, and a kind of is the die casting aluminium section bar, and a kind of is cast iron.The die casting aluminium section bar is to utilize the mould that designs shape that aluminium alloy compression casting is formed, can form many thin-walleds and irregularly shapedly satisfy operating needs, but it comes with some shortcomings: the cost of aluminium and other alloy material is higher, complex manufacturing, mold design, shaping that need be independent, product quality is subjected to the influence of characteristics such as shrinkage percentage of material bigger, the product precision of producing is not high, and it is attractive in appearance to place air that oxidation, surface staining, influence easily took place after a period of time.The lift cabin door sill of cast iron is generally solid, and weight is heavier, is difficult to it is carried out operations such as surface finish, boring, tapping after the casting, and brittle failure easily takes place material, and the aesthetic measure on surface is relatively poor, is generally used for cargo lift.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and the lift cabin door sill of a kind of cost-cutting, simplified processing process, enhancing aesthetic measure is provided.
In order to achieve the above object, the technical scheme that the utility model adopted is: a kind of lift cabin door sill, comprise the sill body, described sill body is a stainless steel materials, the place's bending of one end of described sill body goes out at least one and is used for the guide groove that matches with the elevator orienting lug, and described guide groove extends along the sense of motion of orienting lug; The thickness of described stainless steel materials is t, and described guide groove has groove width b, and groove width b is not less than 5 times of thickness t, and described guide groove has groove depth h, and groove depth h is not more than 1.7 times of groove width b.
Also be bent with connecting portion on the described sill body, described connecting portion welds mutually with the elevator support or is fastened and connected.
The surface of described sill body can adopt at least a in paint, minute surface, hairline, the etch process to carry out surface treatment, and surface treated sill body can also be anti-skidding.
The thickness t of described sill body is 1 millimeter to 2.5 a millimeters scope.Described guide groove has radius bend R, and radius bend R is not less than 0.4t.
Because the employing of technique scheme, the utlity model has following advantage: the good looking appearance, generous that utilizes stainless steel materials, the superficial hardness height, and the abrasion resistant characteristics have been made later-model lift cabin door sill, and the drawback that is difficult to the processed complex profile at the stainless steel materials bending technique, designed a kind of structure that is suitable for the simple lift cabin door sill of cross sectional shape of bending technique, pass through bending and molding during manufacturing, simplified manufacturing process, need not the manufacturing process of mould, thereby reduced cost, obtained very high practical value.
Description of drawings
Fig. 1 is a section drawing of the present utility model;
Fig. 2 is a block diagram of the present utility model.
Wherein, 1, the sill body, 2, guide groove, 3, connecting portion.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail:
Referring to Fig. 1, Fig. 2, a kind of lift cabin door sill, comprise sill body 1, described sill body 1 is a stainless steel materials, the place's bending of one end of described sill body 1 goes out at least one and is used for the guide groove 2 that matches with the orienting lug of elevator cab door, hoistway layer every plate bottom, described guide groove 2 extends along the sense of motion of orienting lug, and the motion of orienting lug is play the guiding role.Also be bent with connecting portion 3 on the described sill body 1, described connecting portion 3 welds mutually with car, hoistway support or is fastened and connected.
The material of described sill body 1 is a corrosion-resistant steel, and corrosion-resistant steel is a kind of good sheet material, and its resistance to abrasion and impact resistance are particularly suitable for as guiding parts.The surface of described sill body 1 can adopt at least a in minute surface, hairline, the etch process to carry out surface treatment, to improve the surface quality of described sill body 1, make the surface of described sill body 1 have skid resistance, and make its surface have appearance brighter and cleaner, attractive in appearance.
For the such cross sectional shape complexity of lift cabin door sill, parts that structure space is little, traditional roll, the more or less freely realization of foundry technique, yet adopting bending technique but is to be difficult to processing, thus must carry out unique design to described guide groove 2, to satisfy the bending technique flow process.
At this, the thickness t that selection is used for the stainless steel materials of lift cabin door sill is 1 millimeter to 2.5 a millimeters scope, if adopt very thin sheet material, then its intensity is limited; If adopt very thick sheet material, then it is difficult to bending.Described guide groove 2 has radius bend R, and radius bend R is not less than 0.4t, and this is according to the characteristics design of bending technique.Described guide groove 2 has groove width b, and groove width b is not less than 5 times of thickness t, and such design is when making Bending Processing, and the bottom land of described guide groove 2 part can be processed smoothly.Described guide groove 2 has groove depth h, groove depth h is not more than 1.7 times of groove width b, because the bottom land part of the slot-open-section of the described guide groove 2 of elder generation's bending, the described guide groove 2 of back bending when Bending Processing, design groove depth h like this, purpose is to guarantee described guide groove 2 in the bending process, and the slot-open-section of described guide groove 2 and bottom land part can not interfere adding man-hour.
A preferred embodiment comparatively: the thickness t of choosing stainless steel materials is 2 millimeters, groove width b is 12 millimeters, groove depth h is 20 millimeters, such sill is easy to Bending Processing, the product that processes is good looking appearance, light weight not only, and satisfy the function that leads fully, and have very big wear-resisting, impact resistance.
