That is, the construction lift emergency exit control sensing device has connected the emergency exit control sensor 20 to the standby contact of the lift electric circuit so that the emergency exit can be arbitrarily used without permission of the safety manager.

Referring to FIG. 2, the construction lift emergency exit control sensing apparatus according to an embodiment of the present invention includes an emergency exit opening formed in a ceiling of a construction lift 10 lifted and lowered along a supporting post, And an emergency exit control sensor 20 for detecting an operation.

The emergency exit control sensor 20 is electrically connected to a control module 30 for controlling and controlling the elevation of the elevator 10. That is, the emergency exit control sensor 20 is electrically connected to the standby contact STAND BY of the control module 30. More specifically, the emergency exit control sensor 20 is electrically connected to a door opening / closing detection device for detecting whether the door of the construction lift 10 is opened or closed and a safety device 32 (safety device for detecting overspeed of the construction lift 10) Lt; / RTI >

Accordingly, the control module 30 can stop the elevating operation of the construction lift 10 when an operation of opening the emergency exit door 11 by the emergency exit control sensor 20 is detected.

In other words, when the operation of opening the emergency exit door 11 by the emergency exit control sensor 20 is detected, the connection between the emergency exit control sensor 20 and the standby contact of the control module 30 is automatically disconnected . The control module 30 may then output a stop control signal for the elevator 10.

That is, after the elastic portion 23 is fitted around the exit-side control sensor 20 and the elastic portion 23 is seated in the holder portion 22b of the sensor holder 22, The formed hook is pushed into the engaging hole of the holding plate 21. As a result, the pair of hooks and the fixing portion 22a are elastically deformed and then restored, and the hooks pass through the fitting hole, whereby the sensor holder 22 is coupled to the fixing plate 21. [

The emergency exit sensor 20 includes a detection sensor attached to the emergency exit door 11 so as to detect the on / off state of the emergency exit. At this time, it is preferable that the sensing sensor is realized as a contact switch which is operated by contact, but it may be constituted by a contactless switch such as an optical sensor or a magnetic sensor.

In the present invention, as shown in FIG. 2, an emergency exit detecting sensor (for example, a proximity detecting sensor) for detecting the on / off state of a lift emergency exit is installed in the emergency exit door 11, It is possible to reduce a site safety accident such as a sudden stoppage of running (for example, power failure, A / S occurrence, etc.) during a lift operation.

Meanwhile, the control module 30 is implemented as a printed circuit board on which a plurality of electronic elements are mounted, and the printed circuit board is disposed inside the case.

At this time, the case may be made of a polypropylene resin composition having excellent mechanical properties.

More specifically, the polypropylene resin composition is a low-gloss polypropylene resin composition comprising an ethylene-propylene block copolymer, wherein the ethylene-propylene block copolymer is composed of a homopolypropylene polymer and an ethylene-propylene copolymer, The ethylene-propylene block copolymer has a melt index of 5 to 30 g / 10 min at 230 DEG C and 2.16 kg of ASTM D1238, and the propylene homopolymer has a propylene homopolymer The viscosity ratio (? XS /? HomoPP) has a characteristic of 3 to 8.

The ethylene-propylene block copolymer resin may be composed of a homopolypropylene polymer portion and an ethylene-propylene copolymer portion as a rubber component.

The weight ratio of the ethylene-propylene copolymer to the ethylene content in the ethylene-propylene block copolymer is 0.5 to 2.0, preferably 1.0 to 2.0, and more preferably 1.0 to 1.5. When the weight ratio is less than 0.5, it is difficult to exhibit the low-gloss characteristics of the polypropylene resin. When the weight ratio is more than 2.0, the polypropylene resin composition which can lower the glossiness but the flexural rigidity of the composition is lowered and satisfies flexural rigidity and low gloss simultaneously There is a difficulty in obtaining.

The melt index of the ethylene-propylene block copolymer resin composition is 5 to 30 g / 10 min (ASTM D1238, 230 ° C / 2.16 kg, Melt Index, MI), preferably 15 to 30 g / 10 min, Is 20 to 30 g / 10 min.

The inherent viscosity ratio (? XS /? HomoPP) of the xylene-soluble portion (XS) and the propylene homopolymer of the ethylene-propylene block copolymer is 3 to 8, preferably 4 to 6. When the intrinsic viscosity ratio (? XS /? HomoPP) is less than 3, a flow mark may be generated in the appearance of the molded article at the time of injection of the polypropylene resin composition. If the intrinsic viscosity ratio is more than 8, none.

The ethylene content of the ethylene-propylene copolymer is 40 to 70 mol%. If the ethylene content is less than 40 mol%, the impact resistance of the resin composition is undesirably low. If the ethylene content is more than 70 mol%, the hardness, heat resistance, and the like may deteriorate and the surface of the injection molded article may become sticky.

The ethylene-propylene copolymer as the rubber component is 5 to 20% by weight, preferably 10 to 17% by weight based on the total weight of the ethylene-propylene block copolymer. If the content is less than 5% by weight, the gloss and impact strength may be lowered due to the low rubber component content, and if it exceeds 20% by weight, the flexural strength and tensile strength may be relatively lowered. The content of the ethylene-propylene copolymer may be measured using a solvent extract, and the solvent may be a xylene extract.

The polypropylene resin composition may further comprise 0.1 to 0.5 parts by weight, preferably 0.02 to 0.3 part by weight, of a heat stabilizer based on 100 parts by weight of the polypropylene resin composition in order to increase the heat stability of the injection molded article. If the content of the heat stabilizer is less than 0.1 parts by weight, it is difficult to secure long-term heat stability. If the content is more than 0.5 parts by weight, dissolution of the heat stabilizer may occur or cost efficiency may be deteriorated. Specific examples of the heat stabilizer include tetrakis (methylene (3,5-di-t-butyl-4-hydroxy) hydrosilylate), 1, 3,5-trimethyl-tris (3,5-di-t-butyl-4-hydroxybenzene) and tris (2,4-di-t-butylphenol) phosphite.

In the present invention, the ethylene-propylene block copolymer resin is a resin in which a homopropylene polymer portion and an ethylene-propylene copolymer portion are polymerized stepwise, and the polymerization can be carried out in the presence of a Ziegler-Natta catalyst.

The polymerization method may be a method and reaction conditions commonly known in the technical field of the present invention such as a slurry method, a bulk method, a vapor phase method and the like. Specifically, the ethylene-propylene block copolymer resin is produced by polymerizing homopolypropylene through two or more reactors in a first polymerization step, adding ethylene and propylene to the homopolypropylene produced in the second polymerization step, Propylene copolymer portion can be polymerized. The first polymerization step and the second polymerization step may be carried out in the same polymerization reactor or in different polymerization reactors. For example, the polymerization can be carried out in the presence of a catalyst system comprising a Ziegler-Natta catalyst and an external electron donor, and a gas phase polymerization reactor for synthesizing an ethylene-propylene copolymer and two or more bulk polymerization reactors for synthesizing homopolypropylene in the presence of hydrogen gas May be carried out in a polymerization facility.

The melt index of the homopolypropylene synthesized in two or more reactors synthesizing the homopolypropylene may be 20 to 100 g / 10 min (measured at 230 ° C, 2.16 Kg) in the final reactor. The melt index in each reactor for synthesizing two or more homopolypropylene can be operated so as to decrease in turn, and conversely, the melt index in each reactor can be operated in the same manner. Next, the synthesized homopolypropylene is moved to a gas-phase reactor in which ethylene-propylene copolymerization is carried out and ethylene-propylene block copolymer is continuously copolymerized with a homopolypropylene solid component as ethylene and propylene are charged simultaneously . The ratio of the ethylene content to the total gas in the gas phase reactor may be 0.30 to 0.90 (molar ratio), preferably 0.40 to 0.80, more preferably 0.50 to 0.70.

The molded product injected with the composition having the above-described composition exhibits a low gloss and is excellent in mechanical properties, so that it can be appropriately responded to changes in the external environment when it is applied as a case.

On the other hand, a coating layer coated with a composition for anti-fouling coating is formed on the surface of the case to effectively prevent and remove the adhesion of the contaminants. The composition for antifouling coating contains boric acid and sodium carbonate in a molar ratio of 1: 0.01 to 1: 2, and the total content of boric acid and sodium carbonate is 1 to 10% by weight based on the total aqueous solution. In addition, sodium carbonate or calcium carbonate may be used as the material for improving the coating property of the coating layer, but sodium carbonate is preferably used. The molar ratio of boric acid to sodium carbonate is preferably 1: 0.01 to 1: 2. If the molar ratio is out of the above range, the coating property of the substrate may be decreased or the moisture adsorption on the surface of the coating may increase.

The boric acid and sodium carbonate are preferably used in an amount of 1 to 10% by weight based on the total weight of the composition. When the amount is less than 1% by weight, the coating properties of the base material deteriorate. When the amount exceeds 10% by weight, easy to do.

On the other hand, as a method of coating the present anti-fouling coating composition on a case, it is preferable to coat it by a spray method. In addition, the thickness of the final coating film on the case is preferably 500 to 2000 angstroms, and more preferably 1000 to 2000 angstroms. When the thickness of the coating film is less than 500 ANGSTROM, there is a problem that it deteriorates in the case of a high-temperature heat treatment. When the thickness of the coating film is more than 2000 ANGSTROM, crystallization of the coating surface tends to occur.

Further, the composition for antifouling coating may be prepared by adding 0.1 mol of boric acid and 0.05 mol of sodium carbonate to 1000 mL of distilled water and then stirring.

On the other hand, the outer surface of the case may be coated with a temperature-coloring layer whose color changes according to temperature. The temperature discoloring layer is coated on the surface of the case with two or more color-changing substances whose color changes when the temperature is equal to or higher than a predetermined temperature, and is separated into two or more sections according to the temperature change, On the temperature discoloration layer, a protective film layer is coated to prevent the temperature discoloration layer from being damaged. Here, the temperature-coloring layer may be formed by coating a temperature-coloring material having a color-changing temperature of not lower than 40 ° C and not lower than 60 ° C, respectively. The temperature-coloring layer is for sensing the temperature change of the coating material by changing the color depending on the temperature of the case. The temperature-coloring layer may be formed by coating a surface of the case with a color-changing material whose color changes when the temperature of the temperature-coloring layer becomes a predetermined temperature or more. In addition, the temperature discoloring substance is generally composed of a microcapsule structure having a size of 1 to 10 탆, and the microcapsules can exhibit a colored and transparent color due to the bonding and separation phenomenon depending on the temperature of the electron donor and the electron acceptor. In addition, the temperature-changing material has a rapid color change and can have various discoloration temperatures such as 40 ° C, 60 ° C, 70 ° C, and 80 ° C, and such a discoloration temperature can be easily adjusted by various methods. Such a temperature-coloring material may be various kinds of temperature-coloring materials based on principles such as molecular rearrangement of an organic compound and spatial rearrangement of an atomic group. For this purpose, it is preferable that the temperature-coloring layer is formed so as to be separated into two or more sections according to the temperature change by coating two or more temperature-coloring materials having different color-changing temperatures. The temperature-coloring layer preferably uses a temperature-coloring material having a relatively low temperature of the discoloration temperature and a temperature-discoloring material having a relatively high discoloration temperature, more preferably a discoloration temperature of not lower than 40 ° C and not lower than 60 ° C A temperature-coloring layer can be formed using a temperature-coloring material. Accordingly, the temperature change of the case can be checked step by step, so that the temperature change of the paint can be detected, thereby preventing damage to the case due to overheating. In addition, the protective film layer is coated on the temperature discoloration layer to prevent the temperature discoloration layer from being damaged due to the external impact, and it is easy to check whether the discoloration of the temperature discoloration layer is discolored and at the same time, It is preferable to use a transparent coating material having a branching property.

As described above, the present invention is not limited to the above-described embodiment, and it is to be understood that the present invention is not limited to the above embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
