Here, the reinforced plastic may be made by mixing carbon fiber and talcum powder.

The reinforcing plate 200 may further include a fixing member 220 for selectively fixing and coupling the pallet to both ends of the lower side.

The fixing member 220 is integrally formed at the end of the reinforcing plate 200, but protrudes and is bent downward, and coupling holes 221 are formed at both ends for bolt coupling. .

The reinforcing plate 200 may be selectively coupled to the pallet 100 through the fixing member 220 and provide strong fixing force through bolt coupling. For example, when lifting the pallet 100 and the product seated on the upper portion of the reinforcing plate 200 at once, the fixing member 220 maintains a strong fixed state with the pallet 100, and the reinforcing plate 200 If you want to lift only the product seated on the top and the fixing member 220 may be in a state in which the pallet 100 and the binding are released.

Through this configuration of the fixing member 220, work efficiency can be improved, and durability of the pallet 100 can be improved because the pallet 100 is not used together for transportation.

The pallet structure 10 capable of lifting only products according to an embodiment of the present invention may further include a vibration reducing plate 300 and a shock absorbing unit 400.

In one embodiment, the vibration reduction plate 300 is installed on the bottom surface of the pallet 100 to reduce the impact transmitted to the pallet 100.

In more detail, the vibration reduction plate 300 may include a thermal insulation layer 310 and a vibration reduction layer 320 . The thermal barrier layer 310 is for blocking cold air or heat from the floor, and is made of a non-woven fabric using nanofibers and may have high thermal insulation properties. In addition, this thermal barrier layer is formed at the same time as the vibration damping layer to be described later, and can be manufactured quickly and at a low cost compared to forming and bonding each of them as in the conventional method.

The vibration reducing layer 320 is formed below the heat insulating layer 310 and is a layer for absorbing shock and vibration transmitted from the floor, and contains balls made of urethane therein so as to effectively absorb vibration. there is.

Looking at this in detail, the vibration transmitted from the floor surface has a constant wavelength. Although such vibration is generally absorbed by a plate-shaped elastic body, when the vibration is in contact with a spherical elastic body having an integer ratio of wavelengths, it can be more easily absorbed and attenuated by resonating with the elastic body. Therefore, in the case of the present invention, it is possible to absorb the vibration more effectively by including a polyurethane ball having a diameter of 0.1 to 5 mm inside the vibration reducing layer. At this time, the polyurethane balls may be used by mixing spherical balls having a diameter of 0.1 to 5 mm in a uniform ratio in order to absorb various vibrations.

In addition, as described above, the heat blocking layer 310 and the vibration reducing layer 320 may be manufactured in one process. To this end, in the heat blocking layer and the vibration reducing layer, installing a collection plate under the injection nozzle and applying a high voltage between the injection nozzle and the collection plate; supplying the melted or melted polymer through the injection nozzle; Discharging the molten polymer to the outside of the injection nozzle by rotating a centrifugal rotation unit in which the injection nozzle is installed; forming nanofibers on an upper portion of the collecting plate by applying a high voltage as the discharged polymer moves downward; Forming a thermal barrier layer by ultrasonically welding the nanofibers; arranging a polymeric vibration absorber on top of the thermal insulation layer; It may be prepared by forming a vibration reducing layer by applying a vibration reducing layer forming compound on top of the polymer absorber.

The nanofibers are produced by spraying polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyethylene terephthalate, polycarbonate, or mixtures thereof in a solvent type or molten form to have a diameter of 50 to 100 nm and electrospinning. As in the method, the polymer may be sprayed in a solvent type or a molten type onto a collection plate to produce nanofibers, and then made into a nonwoven fabric to form the thermal barrier layer.

Looking at the nanofiber manufacturing method in detail, a polymer resin is dissolved in a solvent or supplied to a melting tank, heated to make it into a molten state, and then the dissolved or melted polymer resin is supplied to a spray nozzle.

At this time, one or more injection nozzles may be installed in the direction of the collecting plate installed in the front, and a centrifugal injection nozzle having a plurality of nozzles radially arranged on the outer surface of the centrifugal rotation unit may be used.

When a plurality of injection nozzles are disposed in the direction of the collection plate, a voltage of 5 to 40 kV to the injection nozzle and a voltage of 1 to 10 kV to the collection plate may be applied using a high voltage generator, and the injected polymer resin is nanofibers can be formed.

At this time, if the voltage applied to the injection nozzle is less than 5 kV, the formation of nanofibers may not be smooth, and if a voltage exceeding 40 kV is supplied, the supplied power reaches the collector plate to generate an arc or generate nanofibers. can be oxidized or melted.

In addition, a voltage of 1 to 10 kV may be supplied to the collection plate so that the nanofibers may be attached by applying electrostatic attraction to the generated nanofibers. When the voltage applied to the collection plate is less than 1 kV, it may be difficult to collect nanofibers due to weakening of the electrostatic attraction, and when a voltage exceeding 10 kV is applied, an arc may be generated by being energized with the injection nozzle.

In the case of using a centrifugal sprayer, a plurality of sprayers may be radially installed around the centrifugal rotation unit, and centrifugal force may be applied to the polymer resin to be sprayed as the centrifugal rotation unit rotates during injection. Molten or melted polymer resin may be introduced into the centrifugal rotation unit, and may be supplied to the spray nozzle by rotation of the centrifugal rotation unit.

In addition, as described above, a high voltage generator is electrically connected to the injection nozzle to apply a voltage of 5 to 40 kV. At this time, it is possible to apply the high voltage by connecting the high voltage generator to each of the spray nozzles, but since the spray nozzle is connected to the centrifugal rotation unit, it is also possible to connect the high voltage generator to the centrifugal rotation unit and simultaneously apply the high voltage.

In addition, a collection plate is provided on the side or bottom of the centrifugal injector, and as described above, the collection plate can effectively collect nanofibers generated by applying a voltage of 1 to 10 kV using a high voltage generator. can

As described above, it is possible to form the thermal barrier layer by fusing the nanofibers using ultrasonic waves after the spinning is completed.

After the formation of the thermal barrier layer 310 is completed, spherical balls made of the urethane resin may be arranged as a polymer vibration absorber on the upper portion of the thermal barrier layer. At this time, it is as described above that the urethane balls are randomly arranged to absorb vibrations having various wavelengths.

After the arrangement of the polymeric vibration absorber is completed as described above, the vibration reducing layer may be formed by applying a compound for forming the vibration reducing layer. At this time, the compound for forming the vibration damping layer is manufactured to have an appropriate viscosity to form a vibration reducing layer including the polymer shock absorber therein, and is impregnated into a part of the heat insulating layer to add a role of fixing the heat insulating layer. can be done with In this process, it is preferable to impregnate 10 to 50% of the thickness of the thermal insulation layer with the compound for forming the vibration damping layer. When less than 10% of the thermal insulation layer is impregnated with the compound for forming the vibration damping layer, the fixing force of the thermal insulation layer may be reduced, and when the compound for forming the vibration damping layer is impregnated with more than 50%, the thermal insulating property may be deteriorated.

In one embodiment, the shock mitigating unit 400 is installed on the lower bottom surface of the vibration reducing plate 300 to primarily relieve vibration or impact from the floor.

The case 410 forms the exterior of the earthquake-resistant module 2000 and may have a rectangular shape.

One side of the lower plate 420 may be fixed to an inner bottom surface of the case 410 and a lower plate groove 421 may be formed on the other side toward the bottom surface.

One side of the ball bearing 430 is in close contact with the lower plate groove 421, and the other side protrudes upward in a circular shape so that it can revolve along the plate surface of the fixed plate groove according to an earthquake or vibration load.

The upper plate 440 has a ball bearing groove 441 corresponding to the shape of the ball bearing 430 on one side to fasten a part of the bearing 2300, and a middle plate 442 on the other side to fit inside the case 410. It can move together with the ball bearing 430.

The lower surface of the lower plate groove 421 may be formed round to correspond to the ball bearing 430 .

The case 410 may be formed to be spaced apart from the upper plate 440 at a predetermined interval.

The case 410 may include a vibration damping agent 412 , a coupling body 413 , a seating groove 411 and a fixture 414 .

When the ball bearing 430 revolves along the upper plate 440 along the lower plate groove 421, the vibration damping agent 412 may absorb vibration transmitted from the upper plate 440 in response thereto.

The assembly 413 is integrally fastened with the vibration damping agent 412 in a 'b' shape, the circumferential surface is fastened to the inner surface of the case 410, and a fixing groove is formed on the upper side in close contact with the bottom surface of the housing. can

The seating groove 411 may fix the lower plate 420 to the upper side of the bottom of the case 410 .

The fixing body 414 is fastened between the coupling body 413 and the lower plate 420 to stably fix the fixing plate to the seating groove 411 .

The upper plate 440 may include a fastening portion 443 and a fixing pin 4431 that protrude from the middle plate 442 to the upper surface of the case 410 and are fixed to the vibration reducing plate 300 .

An embodiment of the configuration according to the present invention is described in detail as follows.

The shock mitigation unit 400 operates so that the vibration reduction plate 300 can be easily fixed from shaking such as vibration caused by an external environment.

The lower plate groove is formed in a circular shape on the bottom surface of the lower plate, and the lower plate is fixed by the groove so that the horizontal movement of the lower plate on the bottom surface of the case is restricted through a strong coupling.

The ball bearing rotates on the outer circumferential surface of the fixing plate groove, and it is possible to prevent damage to the side surface of the ball bearing even when it comes into contact with a locking portion (not shown) of the lower plate groove.

A ball bearing groove corresponding to the shape of the ball bearing is formed on one side of the upper plate to accommodate an area of the ball bearing, and an intermediate plate formed in the same disk shape as the lower plate is formed on the other side.

The upper plate moves like a ball bearing in the case according to the revolution of the ball bearing.

The upper plate can dissipate the vibration load and minimize diffusion to the vibration reduction plate 300 while revolving and moving in the lower plate groove along with the ball bearing according to the vibration load acting in the horizontal direction.

At this time, the vibration damping body is disposed at a certain distance in the circumferential direction of the top plate, and when the top plate revolves along the ball bearing, the top plate is limited to the hanging part and absorbs the shock transmitted from the top plate to limit the movement of the top plate. there is.

The assembly has a cross-sectional shape of an approximate 'B' shape and can be formed in a fixing groove (not shown) capable of fixing the vibration damping body, so that the vibration damping body is formed in the fixing groove formed in the assembly without a separate connecting member. It can be inserted to maintain a solid fastening state.

Therefore, the load transmitted to the vibration reduction plate 300 fastened to the shock mitigation unit 400 is reduced by dissipating the load transmitted while the ball bearing and the upper plate revolve along the lower plate groove formed inside the lower plate through horizontal displacement. Therefore, damage to the vibration reducing plate 300 and the pallet 100 can be prevented.
