DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a non-slip moving work (hereinafter referred to as a "non-slip moving work") coated with stainless steel according to preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The anti-slip moving work according to the present invention may include components of a general moving work. For example, there are provided a body case for providing an installation space for each component, a handrail support portion provided on the body case, a handrail provided on the handrail support portion, a footrest provided on the body case, And a mechanical room part for providing power to rotate the handrail and the foot plate, which can be changed depending on the installation environment and the like.

The present invention includes a coating layer provided on the surface of the foot, which is one component of such a general moving work.

At this time, the power of the moving work is transmitted to the speed reducer directly connected to the motor as the motor provided in the machine room is driven, and at the same time, the power is transmitted to the driving chain by the driving sprocket coupled to the speed reducer to rotate the driven sprocket. At the same time, the driving terminal gear coupled on the same axis as the driven sprocket rotates the foot plate finally by driving the press chain coupled with the foot plate.

Here, the body case, the handrail support portion, the handrail, and the foot plate according to the present invention are well known in the art and will not be described in detail.

The coating layer according to the present invention is provided on the surface of a foot plate and improves the corrosion resistance and wear resistance of the foot plate made of aluminum or the like and makes the roughness of the foot plate rough, thereby preventing slippage of the user Function.

Such a coating layer is composed of a melt of martensitic stainless steels, a melt of austenitic stainless steel, or a mixture thereof.

The martensite is one of the structures that can be seen in the quenched steel, and refers to a structure formed by the transformation of atoms in the metal crystal by the collective slight movement not by diffusion. Since the atom is not moved by diffusion, its composition does not change. Generally, it is very hard and has excellent abrasion resistance, but its corrosion resistance and ductility are weak.

Since the martensitic stainless steel is a material used for improving abrasion resistance against the footing surface, it can be used solely in a coating layer of a high-level moving work which is hardly penetrated mainly by rainwater or the like.

Specifically, for example, SUS 400 series such as SUS (or STS) 403, 410, 416, 420J1, 420J2, 420F, 431, 440A, 440B, 440C and 440F may be used as the martensitic stainless steel. It is recommended to use SUS 420.

The austenite means gamma-iron, i.e., gamma-solid solution, which solidifies carbon, and is a kind of quenched steel structure. The crystal structure is a face-centered-cubic-lattice structure that is formed when the steel is heated to the A1 transformation point (726 ° C) or higher. The solubility of carbon is 2.1% at 1140 ° C, and depending on the carbon content, the austenite has different physical and mechanical properties. These austenitic stainless steels are generally excellent in corrosion resistance and ductility, but have a low hardness.

Specifically, for example, SUS 300 series such as SUS (or STS) 301, 302, 303, 304, 305, 309S, 310, 316, 317, 321 and 347 may be used as the austenitic stainless steel, It is recommended to use SUS 304.

The coating layer composed of the molten material of the martensitic stainless steel and the austenitic stainless steel improves the corrosion resistance, which is a property of the martensitic stainless steel, and can be used for the coating layer of the under layer and the underground moving work.

More specifically, the mixture contains 40 to 60 wt%, preferably 50 wt% of martensitic stainless steel and 40 to 60 wt%, preferably 50 wt% of austenitic stainless steel, based on 100 wt% Can be mixed and used.

At this time, if the addition amount of the martensitic stainless steel and the addition amount of the austenitic stainless steel are out of the upper limit value and the lower limit value, not only one of the corrosion resistance and the abrasion resistance can not be sufficiently provided but also the slip prevention function I will not.

On the other hand, as the different kinds of stainless steels are melted and mixed with each other, the structure is coarsened. That is, when observed with a microscope or the like, the stainless steel becomes lumpy and coarsened as compared with the case where each stainless steel is alone, and when such a melt is applied to the surface of the foot plate, the roughness is increased, thereby contributing to a slip prevention effect.

In the coating layer of the present invention, a snowball-shaped anti-slip particle having a size of 5 탆 to 15 탆 may be formed. The non-slip particles are formed in the coating layer when the melts of the different kinds of stainless steel (martensitic stainless steel and austenitic stainless steel) are sprayed with the foot plate in a state where they are spaced apart from the foot of the moving work by an interval of 270 to 330 mm. Such non-slip particles increase the roughness of the coating layer and improve the anti-slip effect.

Figs. 3 to 5 are test reports including an enlarged photograph for explaining the structure before and after the mixing of stainless steel. Fig. 4, the texture of SUS304, which is a kind of austenitic stainless steel, is enlarged 100 times (Photo 1), 200 times (Photo 2), and 500 times (Photo 3) 5, the structure of SUS420, which is a type of martensitic stainless steel, is shown 100 times (Photo 1), 200 times (Photo 2), and 500 times (Photo 3).

Referring to FIG. 4, the structure obtained by melting and mixing the two by the same weight is enlarged 100 times (photograph (4)), 200 times (photograph (5) A picture is displayed.

Comparing the photographs of the above tissues, it can be seen that when the austenitic stainless steels and the martensitic stainless steels are present singly, when the two are mixed, the tissues are aggregated in a large lump unit (coarsened).

In addition, the coating layer may be formed to a thickness ranging from 80 to 150 mu m.

At this time, if the thickness of the coating layer is less than the lower limit value, the surface of the foot plate may be exposed partially as the use period expires. That is, sufficient durability and economical efficiency can not be expected, and when the raw material of the foot plate is exposed, the slip prevention effect can not be expected, and the corrosion is likely to proceed rapidly.

If the thickness of the coating layer exceeds the upper limit value, interference may occur with other parts of the moving workpiece. However, if the thickness of the coating layer exceeds the upper limit value, the seating of the foot plate and the carrying cart wheels is unstable, and the carrying cart is fixed on the foot plate. The problem may arise.

In addition, the coating layer may be provided with a sliding buffer ball of a minute size.

The sliding buffer ball is contained in the coating layer to increase the contact area between the surface of the coating layer and the shoe, and has a spherical shape having an outer diameter of 5 mu m to 15 mu m.

Such a sliding buffer ball may be formed of a ceramic material depending on the application to improve abrasion resistance and durability, or may be formed of a polymer material to improve the cushioning feeling. At this time, the sliding buffer ball may be formed in a hollow shape so as to reduce the weight of the coating layer.

Here, as the ceramic material, a ceramic material having a melting temperature of 2,700 ° C or higher may be used, and zirconia or the like is preferably used.

In one embodiment, the sliding buffer ball according to the present invention is preferably made of a ceramic material so as to improve abrasion resistance and durability in a place where a cart for carrying articles such as a department store, a mart or a complex shopping mall is used.

More specifically, when a sliding buffer ball made of a ceramic material is mixed with a coating agent constituting the coating layer, it is preferable that the sliding buffer ball is mixed with 1 to 10 parts by weight of a sliding buffer ball with respect to 100 parts by weight of the coating agent. This is to ensure sufficient durability in the coating layer composed of the coating agent and the sliding buffer balls and to maximize the contact area between the coating layer and the shoe so as to prevent slippage of shoes due to rainwater.

In another embodiment, the sliding cushioning ball according to the present invention is preferably made of a polymer material so that a comfortable cushioning feeling can be provided to a user in a place where a cart for carrying articles such as a subway history is not used.

More specifically, when a sliding buffer ball made of a polymer material such as polyurethane is mixed with a coating agent constituting the coating layer, it is mixed with 0.1 to 3 parts by weight based on 100 parts by weight of the coating agent.

When the amount of the sliding buffer ball is 1 part by weight in the case of the ceramic material sliding buffer ball and less than 0.1 part by weight in the case of the polymer material sliding buffer ball with respect to 100 parts by weight of the coating agent, Not enough is enough. If the amount of the sliding buffer balls is more than 10 parts by weight of the ceramic material sliding buffer balls and less than 3 parts by weight of the polymer material sliding buffer balls with respect to 100 parts by weight of the coating agent, the ruggedness of the coating layer becomes worsened, .

If necessary, the anti-slip moving work according to the present invention may be provided with a slip plate on the surface of the foot plate.

The slip prevention plate is attached to the foot plate to limit the movement of the shoe when the footwear of the pedestrian slides due to rain or the like, and may be formed in a rectangular parallelepiped shape.

The slip prevention plate may be integrally formed with the foot plate, or may be separately attached to the foot plate after being manufactured separately from the foot plate. At this time, the slip prevention plate made of the same material as the footrest is formed of the same material as the footrest, and the slip prevention plate separately manufactured from the footrest is preferably made of ceramic material or stainless steel so as to have excellent corrosion resistance and durability.

It is preferable that the slip prevention plate is provided on the foot plate at regular intervals along the longitudinal direction of the moving work, preferably at intervals of 20 to 25 cm. The slip prevention plate is preferably provided on the foot plate in a row along the width direction of the moving work. This is to support the rear part of the shoe so that the pedestrian does not fall when the shoe slips.

It is preferable that the slip prevention plate is provided on the footrest excluding both ends of the footrest on which the wheels of the cart enter, so as not to hinder the movement of the cart entering the moving work. The length of the slip prevention plate may be changed according to the distance between the right and left wheels of the cart. Therefore, it is preferable that the slip prevention plate is formed to have a length of about 30 cm to 100 cm from the center of the foot plate to the left and right sides of the foot plate.

The slip prevention plate is preferably configured to have a height of 0.5 mm to 2 mm. At this time, if the slip prevention plate is configured to be less than 0.5 mm, it is difficult to support the rear end of the slippery shoes due to rainwater or the like, and if the slip prevention plate is configured to exceed 2 mm, it may cause inconvenience to the movement of the pedestrian.

Hereinafter, a method of manufacturing a non-skid moving work according to an embodiment of the present invention (hereinafter referred to as a "moving work manufacturing method") will be described in detail with reference to the drawings.

6 is a flowchart for explaining a method of manufacturing a moving work according to the present invention.

Referring to FIG. 6, a method for manufacturing a moving work according to the present invention includes a slip prevention plate attaching step (SlOO) for attaching a slip prevention plate to a foot plate, a step S200 for arranging a sprayer at a position spaced apart from the foot plate (S300) for producing a melt, and a melt spraying step (S400) for spraying the melt onto the footplate through the sprayer to form a coating layer.

The slip prevention plate attaching step (S100) is a step of attaching a slip prevention plate to the foot plate of the moving work in a row in the width direction of the moving work along the longitudinal direction of the moving work, Attach to the footplate at 25 cm intervals.

The sprayer arranging step S200 is a step of spraying the molten material from the foot plate of the moving workpiece so that the section where the melted stainless steel melt moves to the sprayed state at room temperature is increased to 270 to 330 mm, .

In this step S200, the distance between the conventional sprayer and the footplate is increased about 1.5 times as much as the distance between the sprayer and the footplate to increase the exposure time of the melt at room temperature, so that the melted material deposited on the footplate is formed into a lump Adjust the distance between the scaffold and the sprayer to be attached to the scaffold.

Further, when the spacing between the sprayer for spraying the melts of the different kinds of stainless steel (martensitic stainless steel and austenitic stainless steel) and the footplate is 270 to 330 mm, the coating layer is coated with a snowball having a size of 5 to 15 [ Shaped anti-slip particles are formed.

In other words, the melt of a single stainless steel may be sprayed at a distance of 270-330 mm from the footboard, or a melt of different types of stainless steel (martensitic stainless steel and austenitic stainless steel) may be sprayed at a distance of 270-330 mm , The coating layer does not form snow flake-shaped anti-slip particles having a size of 5 mu m to 15 mu m.

That is, the present invention can expect an effect of improving the roughness by adjusting the throw distance in the manufacturing process. In addition, when the stainless steel of different tissues is melted and used, not only the texture coarsening is maximized, but also snowball shaped non-slip particles are formed, thereby providing a foundation for providing excellent roughness.

The melt forming step S300 is a step of producing a melt of the stainless steel constituting the coating layer. The melts of the stainless steel include a martensitic stainless steel wire and an austenitic stainless steel wire So that the molten melted material is used.

If necessary, the sliding buffer ball may be mixed in this step S300. At this time, it is preferable that the mixing of the sliding buffer balls proceeds after the melt of the stainless steel is cooled to 2,700 ° C or lower so that the slip cushion ball is not melted when the melt of the martensitic stainless steel and the austenitic stainless steel has a temperature of 2,700 ° C or more .

The melting temperature of the stainless steel melt should be a temperature at which both the martensitic stainless steel and the austenitic stainless steel can be melted. For example, the melting temperature is preferably 3,500 ° C.

In this step S300, the martensitic stainless steel and the austenitic stainless steel are mixed to improve the frictional force of the surface of the foot plate by coarsening the structure, and the martensitic stainless steel is subjected to austenitic stainless steel .

The melt spraying step (S400) is a step of spraying the melt onto the foot plate through the sprayer to form a coating layer on the foot plate, thereby increasing the time for hardening the air in the air before the melt is deposited on the foot plate, thereby increasing the roughness of the coating layer .

In this step S300, the roughness of the coating layer formed on the surface of the scaffold is set to be Rz 17 (탆) or more, preferably 17 to 25, so that the scaffolding effect is imparted to the scaffold not only in normal but also in priority.

On the other hand, according to the present invention, after the stepping plate is separated from an existing moving work installed in a department store, a large-scale distribution point, etc., the step of attaching the slip prevention plate, the step of arranging the sprayer, Can be applied.

In this case, the present invention is characterized in that the present invention comprises a scaffold demolition step of demolishing a scaffold from a moving workpiece before carrying out a slip plate adhering step, a sprayer arranging step, a melt producing step, and a melt spraying step, A contaminant removal step of removing contaminants, and optionally a sanding step of removing the surface coating of the footrest.

Hereinafter, specific examples and experimental examples of the present invention will be described in more detail. It should be understood, however, that the embodiments and examples are for the purpose of promoting understanding of the specific examples of the invention described above, and the scope of rights and the like should not be construed thereby.

Example

[Example 1]

1. A metalizing sprayer capable of spraying a melt was placed at a position spaced 300 mm from a plate made of an aluminum material.

2. SUS 304 of the wire type and SUS 420 of the wire type were charged in the metalizing muffler in the same amount and mixed while being melted at 3,500 ° C to produce a molten product.

3. The sprayer was operated to spray the melt on the plate, and then the plate was dried at room temperature to deposit a coating layer composed of the melt on the surface of the plate.

FIG. 7 is a photograph showing a moving workpiece having a coating layer formed according to the above-described embodiment. In this case, the surface of the footplate is kept in a black-brown color so that visual contamination can be reduced even when the moving workpiece is contaminated.

[Example 2]

Experiments were carried out in the same manner as in Example 1 except that only a wire type SUS 304 was injected into a metalizing scraper in place of the same amount of SUS 304 and SUS 420 to produce a melt.

[Comparative Example 1]

The plate of the same material and size as the plate made of the aluminum material used in Example 1 was used as it was. 8 is a photograph showing a moving work of the prior art, showing a moving work before forming the coating layer of the above embodiment.

[Experimental Example 1]

The plates prepared according to Examples 1 and 2 and the plate of Comparative Example 1 were commissioned by the Korea Footwear and Leather Research Institute and subjected to slip resistance tests for shoes and shoes in a dry and wet environment (test method KS M ISO 11220 : 2004). 9 and 10 are test reports related to the slip resistance test, and the results are summarized in [Table 1] and [Table 2] below.

[Table 1]

[Table 2]

According to the experimental results, it was found that the plate having the coating layer and the existing plate showed improved sliding resistance not only in a dry environment but also in a wet environment. Especially, in a wet environment where a safety accident due to sliding is a concern, a plate having a coating layer formed is more than twice as large as a conventional plate.

Thus, it can be seen that the present invention maximizes the anti-slip effect in a wet environment.

[Experimental Example 2]

Experiments were carried out under the same conditions as in Experimental Example 1, except that the foot plate of the aluminum material (upper and lower concavo-convex grooves: 5.8 mm, lower concave-convex groove spacing: 5.3 mm, concavo-convex groove depth: 10 mm) was used.

As a result, the washer-type foot scaffold on which the coating layer was formed had an interval of 5.7 mm above the concave-convex grooves and a distance of 5.2 mm below the concave-convex grooves. That is, the difference between the thickness of the washer-type footrest having no coating layer and the thickness of the washer-type footrest formed with the coating layer was found to be 0.1 mm, thereby providing enough friction force to the users of the moving walker to prevent slippage, .

[Experimental Example 3]

The plate prepared in Examples 1 and 2 and the plate in Comparative Example 1 were measured for surface hardness, friction coefficient and ten-point average roughness, and the results are summarized in Table 3 below. 11 and 12 are result data showing the results of roughness test before and after coating.

[Table 3]

According to the experimental results, the plate having the coating layer and the existing plate had an effect of improving the surface hardness and the friction coefficient of about 227% (based on Example 1 and Comparative Example 1) based on only the increased effect, It can be interpreted to be about three times better than the existing one. That is, the foot plate made of the conventional aluminum material has a surface hardness of about Hv (Vickers hardness) of about 110, which tends to cause premature wear, whereas the present invention has improved durability as compared with existing foot plates, can do.

In addition, the surface roughness showed a difference of about 5 times or more. That is, it indicates that the roughness is excellent, and it can be seen that the safety of the user can be remarkably improved even when the user moves the moving work or moves with heavy load, even if there is water.

Here, Ra (arithmetic average roughness) means an average value obtained by adding absolute values of deviation from the average line to the measurement curve, Rz (ten point average roughness) is an average value of the elevation Yp of the mountain, Rt (maximum height) is the sum of the height Yp from the average line to the highest point and the depth Yv from the lowest point to the lowest point. it means.

[Experimental Example 4]

In order to compare the corrosion resistance, the surface condition was confirmed after 120 hours by spraying brine onto the footplate of Example 1, Example 2 and Comparative Example 1 (SUS), and the degree of occurrence of redness was summarized in Table 4 below. Fig. 13 is a photograph of the moving work surface according to the first embodiment, Fig. 14 is a photograph of the moving work surface according to the second embodiment, and Fig. 15 is a photograph of the surface of the moving work according to the first comparative example.

[Table 4]

When these data are confirmed, it can be seen that the degree of rust formation remarkably decreases in the case of this embodiment even when exposed to salt water for a long time. That is, it can be confirmed that the embodiment according to the present invention is excellent in corrosion resistance.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that it is possible.
