At this time, the turning angle of one vehicle is 360 degrees divided by the installation number of the vehicle. For example, when two vehicle transporters are installed in the support frame 120, the cover angle of each vehicle transit angle is 180 degrees.

A detailed description of the configuration of the above-mentioned vehicle transmission will be given below.

The vehicle transmission unit includes a lifter 130, a robot device 160 for transferring the vehicle between each lifter 130 and each parking space, and a leveling and holding device for maintaining the level of each lifter 130.

The lifter 130 includes a first frame 140 which is installed on the support frame 120 so as to be able to move up and down and a second frame 140 which is rotatably connected to the first frame 140 via a pivot Frame 150 as shown in FIG.

4 and 5, the robot apparatus 160 is movably installed in a moving path 155 formed at a central portion along the longitudinal direction of the second frame 150. [ This robot apparatus 160 includes a first robot apparatus 160a for supporting the front wheels of the vehicle and a second robot apparatus 160b for supporting the rear wheels of the vehicle. Since the first robot apparatus 160a and the second robot apparatus 160b have the same configuration, the first robot apparatus 160a will be described in detail below.

The robot apparatus 160 includes a main body 161 disposed in the moving path 155 of the second frame 150 and a first driving unit 163 for moving the main body 161 on the moving path 155 A support arm 170 rotatably installed on one side and the other side of the main body 161 to lift the wheel T of the vehicle and a second drive unit 180 for operating the support arm 170 .

First, the main body 161 is disposed on the moving path 155 of the second frame 150 as described above. The main body 161 is moved not only the travel passage 155 formed in the second frame 150 but also the separate travel passage formed in the parking space S. [ For this purpose, it is preferable that the moving passage of the parking space S extends from the moving passage 155 of the second frame 150.

The first driving unit 163 includes a caster 164 having a plurality of longitudinally arranged caster 164 on both sides of the main body 161 and a caster 164 driven by the caster 164 to drive the vehicle lifted through the support arm 170 And a first drive unit (165) for moving the vehicle to the parking room (S).

Here, the caster 164 includes a drive caster 164a directly rotated by the above-described first drive unit 165 and a follower caster 164b interlocked with the rotation of the drive caster 164a.

The first drive unit 165 includes a connection shaft 167 connecting the first drive motor 166 to the casters 164a and 164b disposed to face each other in the main body 110, 166 to a connecting shaft 167 to which the driving caster 164a is connected.

The support arm 170 is for lifting the wheel T as described above, and is provided with a pair of support arms for each wheel. For example, a pair of support arms 170 for supporting one wheel of the vehicle is provided on the left side of the main body 110, and a pair of support arms 170 for supporting the other wheel of the vehicle are provided on the right side of the main body 110. [ (170) are provided as a pair.

As shown in FIG. 6, the contact surface of the support arm 170 (the surface contacting the wheel when the wheel is lifted) is formed of a urethane coating layer (not shown) so as to smoothly lift the wheel, (Not shown). Here, the contact surface of the support arm 170 is provided so as to surround the upper surface, side surface, and part of the bottom surface of the support arm 170.

Accordingly, in the present invention, since the urethane coating layer adheres to the contact surface of the support arm contacting the wheel, it is possible to prevent wear while being stable when supporting the wheel.

In particular, the urethane coating layer 175 of the present invention is provided with a fine surface to reduce noise caused by friction between the wheel and the wheel. For this purpose, the urethane coating layer 175 may be mixed with a polyurethane base, a curing agent and a powder in a weight ratio of 1: 0.5 to 1.5: 1 to 15. Here, numerical ranges of the respective component ratios are considered for formation of fine surface structure, workability, mechanical strength, various chemical resistance and economical efficiency.

Hereinafter, the composition of the urethane coating layer 175 of the present invention will be described in detail.

First, the polyurethane base includes polyoxyethylene glycol, a polyester polyol, a plasticizer, a coloring pigment, a filler and one of water, methyl alcohol, and ethyl alcohol. And the polyurethane base comprises 0.1 to 30% by weight of polyoxyethylene glycol, 5 to 50% by weight of a polyester polyol, 1 to 40% by weight of a plasticizer, 5 to 15% by weight of a color pigment, Ethyl alcohol in an amount of 5 to 40% by weight. The polyurethane base may further contain 0.1 to 3% by weight of a defoaming agent, a precipitation inhibitor, a wetting and dispersing agent, and the like.

First, the polyoxyethylene glycol may have a weight average molecular weight of 200 to 1000 and one or two OH functional groups. These polyoxyethylene glycols may have one or two functional groups. In this case, 0.05 to 30% by weight of polyoxyethylene glycol having one OH functional group in 0.1 to 5% by weight of polyoxyethylene glycol, and 0.05 to 30% by weight of OH functional group It is preferable to use 0.1 to 20% by weight of the polyoxyethylene glycol having two hydroxyl groups. Such polyoxyethylene glycol may be contained in an amount of 0.05 to 30% by weight, and if it exceeds 30% by weight, defective storage stability and surface unevenness of the final cured product may occur. If the content is less than 0.05% by weight, Can be.

The polyester polyol is a natural oil-modified polyester polyol produced by using a semi-drying oil or a non-drying oil having an iodine value (oxo sugar) of 120 or less and has a hydroxyl value of 50 to 250 and an acid value of 3 or less, 2 to 4 is preferably used. More preferably, a polyol having an acid value of 0.5 or less is used. When the polyether polyol is used in the present invention, the dispersibility in the production of the subject is very poor and the storage stability of the subject is poor, resulting in precipitation and caking of the pigment.

Plasticizers are used to increase the flexibility of the product and to increase the self-leveling function. The plasticizers can be used in an amount of 1 to 40% by weight of the main weight. These plasticizers may be dioctyl phthalate (DOP), butyl phthalate (DBP), benzyl butyl phthalate (BBP), dioctyl adipate (DOA), diisobutyl phthalate (DIBP) And so on. Accordingly, in the present invention, it is preferable to use an environmentally friendly plasticizer that does not report environmental toxicity, that is, diisononyl adipate (DINA), citric acid esters and the like, and more preferably, a product having an acid value of 0.1 or less good.

The coloring pigment may be used in an amount of 5 to 15% by weight based on the total weight of the pigment. The use of titanium dioxide, iron oxide yellow, iron oxide red, or the like is preferably used, and the use of a heavy metal pigment known to be toxic is excluded.

The filler may comprise at least one of the group consisting of calcium carbonate, quicklime, potassium bicarbonate, talc and silica and hydrophobic amorphous silica. These hydrophobic amorphous silicas induce fine surface arrangement during curing of the composition. The filler may be used in an amount of 1 to 20% by weight based on the total amount of the filler. Preferably, the amount of the hydrophobic amorphous silica is 1 to 2% by weight and the amount of the filler is 18 to 19% by weight.

At least one of water, methyl alcohol and ethyl alcohol may be contained in the composition in a proportion of 5 to 40% by weight. This is related to the crosslinking reaction of the polyurethane resin and the hydration reaction of the cement, and also to the self-leveling property as a solvent. It is preferable to use distilled water from which the ion component has been removed.

Polyurethane curing agents include isocyanates and latent curing agents. Wherein the isocyanates are selected from the group consisting of diphenylmethane diisocyanate (MDI) or its prepolymer, toluene diisocyanate (TDI) or prepolymer thereof, hexamethylene diisocyanate (HDI) or a polymer thereof and isophorone diisocyanate (IPDI) Use at least one. The latent curing agent may be at least one selected from the group consisting of ethylene carbonate (EC), propylene carbonate (PC), oxazolidine, and aldimine. The diphenylmethane diisocyanate may be a monomer MDI and a polymerized MDI or MDI prepolymer. The NCO% is 20 to 33% and the average number of functional groups is 2 to 3, It is preferable to mix 20 to 50% by weight of isocyanate with the isocyanate. In the present invention, a latent curing agent may be used for controlling the crosslinking density of the workability product. Examples of latent curing agents include latent curing agents such as ethylene carbonate, propylene carbonate, oxazolidine, and aldimine Can be used alone or in combination.

The powder is added to the polyurethane resin so that the cement component in the powder and the water or alcohol component in the polyurethane subject are solidified through the hydration reaction and the silica component is uniformly dispersed in the polyurethane resin to further improve the toughness. Such a powder may contain 5 to 80% by weight of cement, 10 to 80% by weight of silicon, and 1 to 40% by weight of slaked lime. The powder may further contain 0.5 to 1.5% by weight of an AE agent, a water reducing agent, a retarder, an accelerator and the like, and may further be blended at a ratio of 3 to 10% by weight with an admixture such as blast furnace slag or fly ash. At this time, cement can be used as white portland cement, and alumina cement, ultra fast cement or blast furnace slag cement can be mixed and used. In this case, the powder contains 1 to 15% by weight of at least one of white portland cement, 4 to 65% by weight of alumina cement, ultra fast cement and blast furnace slag cement, 10 to 80% by weight of silica, 1 to 40% . The silica used for the powder may contain 1 to 5% by weight of a platelet-shaped fine silica and 5 to 15% by weight of a spherical silica. This is because the content of the plate-like structure and spherical silica is good for the workability and the formation of a fine surface structure to be.

The urethane coating layer 175 produced by the above composition is prepared by stirring the polyurethane base and the polyurethane curing agent so that they can be sufficiently mixed first and then mixing the powder so that the polyurethane resin and the powder are sufficiently mixed to be uniform. And the surface of the urethane coating layer produced in this way has fine unevenness protruding in the size of 0.05 to 5 탆. Such fine irregularities are caused by the curing rate, flowability, and arrangement properties of a silica composition or the like having a plate-like or spherical structure during curing of the urethane coating layer.

Therefore, in the present invention, the noise generated in the process of supporting the wheel T by rotating the support arm 170 can be significantly reduced.

On the other hand, at least one surface of the contact surface of the support arm 170 is provided with a concave-convex structure 171 for smooth adhesion of the urethane coating layer 175 manufactured as shown in FIG. Preferably, an uneven structure 171 may be provided on the upper surface of the contact surface of the support arm 170. That is, according to the present invention, since at least one surface of the contact surface of the support arm 170 is formed of the concavo-convex structure 171, the urethane coating layer 175 is prevented from being peeled off by the support arm 170 even if the support arm 170 is used for a long time. do.

The urethane coating layer 175 adhered to the support arm 170 as described above is formed with chamfering surfaces 176 on both sides thereof in order to minimize deformation of the vehicle even when a load is applied thereto. This is because the deformation of the urethane coating layer 175 can be minimized by moving the portion spreading to both sides by the load of the vehicle to the chamfering surface 176 side.

Referring again to FIGS. 4 and 5, the second drive unit 180 serves to rotate the support arm 170 to lift the wheel T of the vehicle as described above. The second driving portion 180 includes a cylinder 181 and an idle gear 183 engaged with the rod 182 of the cylinder 181. The second driving portion 180 is engaged with the idle gear 183, And a turning gear 184 whose end is coaxially provided.

At this time, in the present invention, it is preferable to use a pneumatic cylinder for the cylinder 181 to pivotally support the support arm 170. This is because, in the present invention, the pneumatic cylinder alone can sufficiently transmit the force to lift the wheel, and when the hydraulic cylinder is used, the fluid is prevented from freezing in the winter when the temperature is low.

It is preferable that the rotating gear 184 use a helical gear instead of a normal spur gear. This is because the helical gear can reduce the noise that can be generated when the support arm 170 is rotated.

The rotating gear 184 may be a circular arc gear. This is because the use of the helical gear can reduce the noise, but the thrust can be generated because the noise and the thrust can be prevented simultaneously when the circular arc gear is used.

7, the leveling and holding device 190 includes a support case 191, a pivot shaft 192 interconnecting both side surfaces of the support case 191, and a pivot shaft 192 fixed to the pivot shaft 192 A locking lever 193 rotatably mounted with a boss 193a and a rotation unit 194 installed in the support case 191 to rotate the locking lever 193, A stopper 197 installed on each parking room and engaged with the locking lever 193 when the locking lever 193 is rotated so as to be exposed to the outside of the support case 191, .

The rotating unit 194 includes an actuator 194a, a plunger 194b extending from the actuator 194a, a link member 194c having one end connected to the plunger 194b and the other end connected to the extending link 193c ).

The rotation restricting member 195 contacts a part of the back surface of the locking lever 193 to prevent the locking lever 193 from further rotating.

The stopper 197 is installed in each parking space S as described above and the locking lever 193 is rotated and locked to the stopper 197 installed in the parking room S to which the vehicle is to be parked.

8, the leveling and holding device 190 according to the present invention is provided with a sensor 198 for detecting the position of each lifter 130 lifted and lowered along the hoistway, And a control unit 199 for controlling overall control of the vehicle.

Here, the sensor 198 is installed in each parking space S and senses the lifter 130 when the lifter 130 approaches the parking room to be parked.

The control unit 199 operates the actuator 194a when the lifter 130 mounted on the vehicle is detected by the sensor 198 installed in the parking room to be parked as described above so that the locking lever 193 is installed in the parking room So that the locking lever 193 is locked by the stopper 197.

The locking lever 193 is rotated and locked to the stopper 197 side so that when the vehicle is moved from the lifter 130 to the parking space S by the robot device 160, The level can be kept constant, so that it is possible to prevent the vehicle from falling off from the lifter 130.
