Description

Technical Field

[0001] The present invention relates to an asphalt concrete heat preservation box, and more specifically to the following asphalt concrete heat preservation box: into which asphalt concrete shipped from an asphalt concrete manufacturing device is loaded, and which can keep the asphalt concrete at a certain temperature until it is discharged after being transported to a road construction site. Background Art

[0002] Generally, asphalt concrete used for road paving (hereinafter referred to as "asphalt concrete") is a black solid or semi-solid substance, the main component of which is a hydrocarbon compound, and is a substance in which a solid component called asphaltene is dispersed in an emulsion component called maltene.

[0003] This asphalt concrete is used by being classified into asphalt concrete for road paving and asphalt concrete for airport paving according to its type, or is used for waterproofing in the paving or construction field.

[0004] In particular, in asphalt mainly used for road paving or airport paving, etc., aggregates such as sand, stone powder, crushed stone, and gravel are mixed and used, and this is called "asphalt concrete".

[0005] In order to maintain the quality of asphalt concrete during the transportation process from the manufacturing factory to the road construction site, this asphalt concrete can be transported using a special asphalt concrete storage device that can transport it while maintaining the temperature of the asphalt concrete.

[0006] As described above, as a mobile asphalt concrete storage device that can store and move asphalt concrete, Korean Registered Utility Model No. 20-0454650 (mobile asphalt concrete storage device, hereinafter referred to as the "prior art") has been publicly disclosed.

[0007] The object of the above prior art is to provide a mobile asphalt concrete storage device, which includes: a heater unit provided on one side of a loading unit; a flow channel extending from the heater unit and communicating with a storage unit; a blower for supplying heat generated in the heater unit to the storage unit through the flow channel; an asphalt concrete discharge unit for discharging the asphalt concrete in the storage unit through a discharge port formed below the loading unit; a first sensor for detecting the temperature of the asphalt concrete in the storage unit; a second sensor provided at the end of the discharge port for detecting the temperature of the asphalt concrete discharged through the discharge port; and a control unit for comparing the detection values of the first and second sensors and controlling the heater unit to generate more additional heat, which is used to compensate for the difference between the detection values of the first and second sensors so as to maintain the temperature of the discharged asphalt concrete at a predetermined temperature. Thus, the asphalt concrete can be easily transported to the construction site in a state of maintaining a certain temperature, and even if the stored asphalt concrete is discharged for construction, the temperature of the discharged asphalt concrete can be maintained at a temperature suitable for construction.

[0008] However, in the above prior art, a flow channel is formed in the loading unit for storing asphalt concrete to supply the heat generated by the heater unit to the flow channel. Therefore, not only is the structure of the loading unit very complicated, but there is also a problem that the heater unit needs to be continuously driven to continuously maintain the temperature of the asphalt concrete.

[0009] In addition, even if heat is supplied to the asphalt concrete in the storage unit through the heater unit, the heat only reaches the outer layer in the storage unit and cannot be fully transmitted to the inside. Thus, it is difficult for the heat to affect the asphalt concrete provided inside the storage unit, and furthermore, there is a problem that it is difficult to maintain the appropriate temperature of the asphalt concrete.

[0010] Moreover, even if heat is well transmitted to the asphalt concrete through the heater unit, when too much heat reaches the inside of the storage unit and the temperature of the asphalt concrete exceeds the appropriate temperature, the temperature of the asphalt concrete discharged from the asphalt concrete discharge unit is too high, and there is a problem that AP flows down from the aggregate and causes a separation phenomenon.

[0011] Therefore, regarding the asphalt concrete storage device for storing and transporting asphalt concrete, there is a practical need to develop an asphalt concrete insulation box as follows: with a simple structure, it can also maintain the appropriate temperature state of the asphalt concrete during the transportation process from the asphalt concrete manufacturing factory to the road construction site for storage and transportation.

[0012] In addition, it is also required to improve the opening and closing device for opening and closing the lid of the asphalt concrete insulation box and the sealing device for sealing the lid into a structure that is easy to operate.

[0116] Next, the technical idea of the present invention will be further specifically described with reference to the drawings. The drawings are only an example shown for more detailed description of the technical idea of the present invention, so the technical idea of the present invention is not limited to the form of the drawings.

[0117] Next, refer to Figures 1 to 13 , and a detailed description will be given to an asphalt concrete insulation box based on an example of the present invention.

[0118] Figure 1 is a perspective view showing the overall state of an asphalt concrete insulation box based on an embodiment of the present invention.

[0119] Refer to Figure 1 , an asphalt concrete insulation box based on an example of the present invention, which houses asphalt concrete shipped from an asphalt concrete manufacturing device and can keep the asphalt concrete at a certain temperature before discharging it after transporting the asphalt concrete to a road construction site.

[0120] In addition, through a plurality of fixing rods 210 and fixing devices 220 formed between the outer box 11 and the inner box 13 of the box body 10, the outer box 11 and the inner box 13 are separated, and a high-temperature heat-insulating material 230 and a moisture-proof agent are filled or coated in the separated space between the outer box 11 and the inner box 13, thereby preventing the temperature of the asphalt concrete loaded inside the inner box 13 from decreasing and enabling the asphalt concrete to maintain an appropriate temperature.

[0121] In addition, heat-insulating resins 240 are respectively provided on the upper side of the separated space between the outer box 11 and the inner box 13 of the box main body 10 and on the lower side of the lid 30 to prevent the outer box 11 and the inner box 13 from directly contacting the lid 30, and block heat conduction caused by the direct contact between the outer box 11 and the inner box 13 and the lid 30, so that the asphalt concrete can maintain an appropriate temperature.

[0122] This asphalt concrete insulation box 1 includes a box main body 10, a lid 30, and a rail-type lid opening and closing device 100.

[0123] Next, with reference to Figures 1 to 13 , the components of the asphalt concrete insulation box according to an example of the present invention will be described in detail.

[0124] The box main body 10 is the main body of the asphalt concrete insulation box 1 for loading asphalt concrete.

[0125] The box main body 10 can be formed in an open-top shape.

[0126] Such a box main body 10 can be composed of an outer box 11 and an inner box 13.

[0127] The outer box 11 is a structure that constitutes the outer surface of the box main body 10. The outer box 11 can be formed with an open top. Therefore, the inner box 13 described later can be positioned inside the outer box 11.

[0128] The outer box 11 can be formed of steel such as a steel plate.

[0129] An inner box 13 can be provided inside the outer box 11. The inner box 13 can be formed in a size smaller than that of the outer box 11 and can be made of the same material as the outer box 11.

[0130] Therefore, since the inner box 13 is formed in a size smaller than that of the outer box 11, the inner box 13 can be easily arranged inside the outer box 11. When the outer box 11 and the inner box 13 are integrated by the fixing rods 210 and the fixing device 220 described later, a separated space is formed between the outer box 11 and the inner box 13, so that the outer box 11 and the inner box 13 are not connected to each other through the fixing device 220 and the fixing rods 210. Thus, not only heat conduction from the inner box 13 to the outer box 11 is prevented, but also by filling or coating a high-temperature heat-insulating material 230 and a moisture-proof agent inside the separated space between the outer box 11 and the inner box 13 and providing a heat-insulating plate 250, heat conduction is more effectively blocked, so that the asphalt concrete loaded in the inner box 13 can maintain an appropriate temperature.

[0131] On the upper sides of the outer box 11 and the inner box 13, a lid 30 can be formed. The lid 30 is formed to cover the upper sides of the outer box 11 and the inner box 13, so that the open upper sides of the outer box 11 and the inner box 13 can be opened and closed.

[0132] The lid 30 can include an upper plate 31 and a lower plate 33.

[0133] The box main body 10 and the lid 30 are coupled to each other by an orbital lid opening / closing device 100, and the orbital lid opening / closing device 100 enables the lid 30 to open and close the upper side of the box main body 10.

[0134] Such an orbital lid opening / closing device 100 may include a guide part 110, a first power cylinder 120, a support part 130, a pressing device 140, and a driving part 160.

[0135] The guide part 110 may include a guide frame 111, guide rollers 113, a guide track 115, and a plurality of rollers 117.

[0136] The guide frame 111 may be formed at the upper parts on both sides of the outer box 11. The guide frame 111 may be formed to be longer than the length of the outer box 11 at the upper parts on both sides of the outer box 11, thereby forming a moving path along which the lid 30 can move. Accordingly, by moving the lid 30 along the guide frame 111 to one side, the asphalt concrete heat preservation box 1 can be opened.

[0137] A plurality of guide rollers 113 may be formed on the upper side of the guide frame 111. The guide rollers 113 may be rotatably provided at regular intervals on the upper side of the guide frame 111. When the lid 30 is moved by a chain 161 and a driving motor 163, the guide rollers 113 can make the movement easier by virtue of the rotation of the rollers.

[0138] Guide tracks 115 may be formed on both sides of the lid 30. Along both sides of the lid 30, with the apex part of the triangular tube facing downward, the guide tracks 115 are provided by joining triangular tubes by means such as welding.

[0139] The guide tracks 115 may be installed on the upper sides of the plurality of guide rollers 113. That is, when the lid 3 is moved by the driving part 160, it can move more easily on the upper side of the guide frame 111 through the guide tracks 115 and the guide rollers 113.

[0140] A plurality of rollers 117 may be formed between the guide frames 111 formed on both sides of the lid 30. When the lid 30 moves along the guide frame 111, the plurality of rollers 117 come into contact with the lower side surface of the lid 30 to make the movement of the lid 30 easier.

[0141] In addition, the plurality of rollers 117 may also be integrally formed on the upper side of one end of the box main body 10. That is, when the upper part of the box main body 10 is formed such that not the entire area is open but only a part of the area is open, the plurality of rollers 117 may be formed in the non-open part on the upper side of one end of the box main body 10.

[0142] A plurality of first power cylinders 120 may be provided on both side surfaces of the box main body 10. One side of each of the plurality of first power cylinders 120 is coupled to the side surface of the box main body 10, and the other side may be coupled to the lower side of the guide frame 111.

[0143] Therefore, by driving the first power cylinder 120, not only can the guiding part 110 be lifted and lowered, but also the cover 30 can be lifted and lowered through the guiding rollers 113 and guiding rails 115 of the guiding part 110. Thus, the first power cylinder 120 can be regarded as a structure that can adjust the lifting and lowering of the guiding part 110 and the opening and closing of the cover 30.

[0144] In addition, on both side surfaces of the box main body 10, a plurality of first lifting guides 121 can be coupled to the lower side of the guide frame 111. The plurality of first lifting guides 121 can guide the lifting and lowering of the guide frame 111 lifted and lowered by the first power cylinder 120. That is, when the guide frame 111 is lifted and lowered by the first power cylinder 120, the plurality of first lifting guides 121 enable the guide frame 111 to be lifted and lowered steadily, so that the lifting and lowering of the guide frame 111 can be stably and correctly implemented.

[0145] Both ends of the support part 130 are coupled to both side surfaces of the box main body 10, and can be formed on the upper side of one end part of the box main body 10.

[0146] The support part 130 can support the guide frame 111 of the guiding part 110, and a driving motor 163 described later can be coupled to the support part 130.

[0147] This support part 130 includes: a pair of second lifting guides 131, coupled to each side surface of a pair of first power cylinders 120 among the plurality of first power cylinders 120; a ∩-shaped support frame 132, with both ends respectively coupled to the above-mentioned pair of second lifting guides 131; a pair of side guiding rollers 135, respectively provided on the inner sides of the side surfaces of the support frame 132 and in contact with the side surfaces of the guiding rails 115; a pair of first fixing blocks 133, respectively formed on the inner side surfaces of the bent parts of the above-mentioned support frame 132; a pair of second fixing blocks 134, coupled to the side surfaces of the guide frame 111 at a certain distance from the first fixing blocks 133; a pair of first support rods 137, with one side coupled to one end part of the guide frame 111 and the other side coupled to the first fixing blocks 133 to support the guide frame 111; a pair of second support rods 138, with one side coupled to the first fixing blocks 133 and the other side coupled to the second fixing blocks 134, thereby supporting the guide frame 111 and the support frame 132.

[0148] A pair of second lifting guides 131 can be coupled to each side surface of a pair of first power cylinders 120 provided on the side end part side among the plurality of first power cylinders 120.

[0149] When the funnel 40 is lifted and lowered by the first power cylinder 120, a pair of second lifting guides 131 are coupled to the lower side of the funnel 40, thereby guiding the lifting and lowering of the support frame 132 that is lifted and lowered together.

[0150] Therefore, through the second lifting guides 131, the support frame 132 can be lifted and lowered steadily, so that the lifting and lowering of the support frame 132 can be stably and correctly realized.

[0151] The support frame 132 can be formed in a ∩ shape. Therefore, both ends of the support frame 132 can be coupled to the respective second lifting guides 131 described above, and the middle portion can be coupled to the lower side of the funnel 40 described later.

[0152] In addition, each of the second lifting guides 131 of a pair of second lifting guides 131 can be coupled to both end portions of the support frame 132. The driving unit 160 can be coupled to the middle portion of the support frame 132, and a pair of first fixing blocks 133 described later can be respectively provided on the inner sides of the bent portions on both sides.

[0153] A pair of first fixing blocks 133 can be provided on the support frame 132. The first support rod 137 described later is coupled to the first fixing block 133, so that the first support rod 137 can be fixed to a specified position through the first fixing block 133. Therefore, the support of the guide frame 111 can be made more firm through the first support rod 137.

[0154] One side of the first support rod 137 is coupled to one end portion of the guide frame 111, and the other side is coupled to the first fixing block 133, thereby fixing the first support rod 137.

[0155] When the guide frame 111 is bent due to its own weight, or when the cover 30 moves upward to the guide frame 111, the first support rod 137 prevents the guide frame 111 from being bent due to the weight of the cover 30, so that the guide frame 111 can be supported in a manner that enables the cover 30 to move stably.

[0156] The first support rod 137 can be formed in a rod shape or a bar shape from steel, and can also be formed from wire and steel wire as needed.

[0157] On the side surface of the guide frame 111, a second fixing block 134 can be coupled. The second fixing block 134 is formed at a certain distance from the first fixing block 133.

[0158] The second support rod 138 described later is coupled to the second fixing block 134, so that the second support rod 138 can be fixed at a specified position through the second fixing block 134. Therefore, the guide frame 111 and the support frame 132 can be supported more firmly through the second support rod 138.

[0159] One side of the second support rod 138 is coupled to the first fixing block 133, and the other side is coupled to the second fixing block 134, thereby being able to fix the second support rod 138.

[0160] A pair of side guide rollers 135 are respectively coupled to the inner surfaces on both sides of the support frame 132 and are arranged to contact the side surfaces of the guide rails 115. Therefore, on the side surfaces of the guide rails 115, the side guide rollers 135 guide the guide rails 115 so that the cover 30 can move more easily to one side.

[0161] On the guide frames 111 formed on both side surfaces of the box body 10, a plurality of pressing devices 140 can be provided.

[0162] The pressing device 140 can include: a pressing jig 141 combined with the guide frame 111 in a shape; and a pressing member 143 provided at a portion where the pressing jig 141 contacts the lid 30.

[0163] The pressing jig 141 can be combined with the lower side of the guide frame 111 by welding or the like.

[0164] The pressing jig 141 can be formed in a shape. When the guide frame 111 is lifted and lowered by the first power cylinder 120, the pressing jig 141 is lifted and lowered together, thereby pressing or releasing the pressure on the upper side of the lid 30.

[0165] Thus, by making the lid 30 closely adhere to the upper side of the box body 10, the box body 10 can be sealed more reliably.

[0166] On the pressing jig 141, a pressing member 143 can be provided. The pressing member 143 can be provided at a portion where the pressing jig 141 contacts the lid 30. When the pressing jig 141 presses toward the lid 30 side, the pressing member 143 can contact the upper surface of the lid 30. At this time, the pressing member 143 presses the upper side of the lid 30 and continuously presses the lid 30 until a pad member 241 described later reaches the maximum contraction point. Therefore, the lid 30 can seal the box body 10 more firmly.

[0167] A driving motor 163 can be combined with the lower side of the holding portion 130. The driving motor 163 can be combined with the middle portion of the support frame 132 by welding or the like.

[0168] The driving portion 160 can include: a chain 161 formed on the upper surface of the lid 30; a driving motor 163 combined with the middle portion of the support portion 130; a driving gear 165 combined with one side of the driving motor 163 and meshing with the chain 161.

[0169] The chain 161 can be provided on the upper surface of the lid 30. The chain 161 meshes with a driving gear 165 described later, and the lid 30 can be moved in the front-rear direction of the asphalt concrete insulation box 1 by driving the driving gear 165 by a driving motor 163.

[0170] At the middle portion of the support portion 130, a driving motor 163 can be combined above the chain 161. The driving motor 163 can use a general motor, or a hydraulic or pneumatic power device driven by hydraulic pressure or air pressure can be used.

[0171] The driving motor 163 rotates the driving gear 165 combined with one side to move the chain 161 meshing with the driving gear 165 to one side, thereby moving the lid 30.

[0172] On the side of the drive motor 163, a drive gear 165 can be coupled. Since the drive gear 165 meshes with the chain 161, the cover 30 can be moved by the driving rotation of the drive motor 165.

[0173] On the upper side of the pressing jig 141, a funnel 40 can be formed by bonding such as welding.

[0174] Since the funnel 40 is coupled to the upper side of the pressing jig 141, the guide frame 111, the pressing jig 141, and the funnel 40 are integrated. Then, by the drive of the first power cylinder 120, the guide frame 111, the pressing jig 141, and the funnel 40 can be lifted and lowered together.

[0175] The funnel 40 can be formed in a trapezoidal shape with a width that widens from the lower side to the upper side.

[0176] Since the funnel 40 is formed with a larger width at the upper side and a smaller width at the lower side, the asphalt concrete discharged from the asphalt concrete manufacturing device can be easily introduced into the inner box 13 through the funnel 40 and loaded. That is, the funnel 40 functions as a conduit for guiding the asphalt concrete to the inside of the inner box 13. Therefore, the asphalt concrete can be loaded more easily into the inside of the asphalt concrete heat preservation box 1.

[0177] The funnel 40 can be formed at a certain interval from the upper side of the cover 30. Therefore, the cover 30 can rise through the separated space formed between the funnel 40 and the cover 30, thereby forming a space where the cover 30 can move.

[0178] Next, the opening drive process of the rail-type cover opening and closing device 100 for the cover 30 will be described.

[0179] In the rail-type cover opening and closing device 100, the guide frame 111 rises upward by the stretching drive of the first power cylinder 120. Then, the pressing jig 141 of the pressing device 140 that presses the upper side of the cover 30 also rises and separates from the upper surface of the cover 30 by a distance, thereby releasing the pressing force acting on the cover 30.

[0180] After that, by continuously stretching and driving the first power cylinder 120, the guide frame 111 lifts upward the guide rails 115 formed on both sides of the cover 30, so that the cover 30 rises and separates from the upper side of the box body 10, thereby enabling the upper part of the box body 10 to be opened.

[0181] Subsequently, the cover 30 that has separated from the upper side of the box body 10 can be moved in one direction along the guide frame 111 by the drive of the drive motor 163. The drive motor 163 drives the drive gear 165 that meshes with the chain 161 provided on the upper surface of the cover 30.

[0182] Therefore, as the lid 30 moves along the guide frame 111, the upper part of the tank body 10 is completely opened, and the asphalt concrete shipped from the asphalt concrete manufacturing device can be loaded into the inner tank 13.

[0183] Next, the closing drive process of the lid 30 by the rail-type lid opening and closing device 100 will be described.

[0184] After the asphalt concrete is loaded into the inner tank 13, the rail-type lid opening and closing device 100 can move the lid 30 in the other direction by driving the drive motor 163.

[0185] When the lid 30 moves in the other direction and reaches the upper side of the tank body 10, the first power cylinder 120 is driven to contract, causing the guide frame 111 to descend. As a result, the lid 30 descends to close the upper side of the tank body 10.

[0186] After that, the first power cylinder 120 is continuously driven to contract, and the pressing clamp 141 of the pressing device 140 presses against the upper surface of the lid 30 to apply pressure to the lid 30, so that the lid 30 can be pressed against the upper side of the outer tank body 10.

[0187] Therefore, through the closing drive process of the aforementioned rail-type lid opening and closing device 100, the pressing device 140 presses the upper side of the lid 30, so that the lid 30 can firmly seal the upper side of the tank body 10.

[0188] A plurality of fixing devices 220 can be provided between the outer tank 11 and the inner tank 13 of the tank body 10 and between the upper plate 31 and the lower plate 33 of the lid 30.

[0189] The plurality of fixing devices 220 provided between the outer tank 11 and the inner tank 13 can penetrate the outer tank 11 on the outside of the outer tank 11 and then connect one end to the inner tank 13 to fix the outer tank 11 to the outside of the inner tank 13.

[0190] Therefore, the outer tank 11 can be supported and fixed to the outside of the inner tank 13 by the plurality of fixing devices 220.

[0191] Through such a plurality of fixing devices 220, a separated space is formed between the outer tank 11 and the inner tank 13.

[0192] In addition, the plurality of fixing devices 220 provided between the upper plate 31 and the lower plate 33 of the lid 30 fix the lower plate 33 of the lid 30 to the upper plate 31, so that a separated space can be formed between the upper plate 31 and the lower plate 33 of the lid 30.

[0193] The plurality of fixing devices 220 provided inside the lid 30 penetrate the lower plate 33 on the outside of the lower plate 33 and then connect one end to the upper plate 31, so that the lower plate 33 is fixed to the upper plate 31.

[0194] That is, a plurality of fixing devices 220 that couple the fixed outer box 11 and the inner box 13, and a plurality of fixing devices 220 that couple the upper plate 31 and the lower plate 33 of the fixed lid 30 are provided, and a separated space is formed between the outer box 11 and the inner box 13 and between the upper plate 31 and the lower plate 33 of the lid 30.

[0195] Therefore, by forming a separated space between the outer box 11 and the inner box 13 and between the upper plate 31 and the lower plate 33 of the lid 30, heat conduction of the asphalt concrete loaded inside the inner box 13 to the outer box 11 and the upper plate 31 of the lid 30 can be prevented. The separated space formed between the outer box 11 and the inner box 13 and between the upper plate 31 and the lower plate 33 of the lid 30 is filled with a high-temperature heat insulating material 230 described later to prevent heat conduction of the asphalt concrete loaded in the asphalt concrete heat preservation box 1 to the outside, so that the temperature of the asphalt concrete can be maintained more efficiently.

[0196] In addition, the lower plate 33 of the lid 30 and the outer box 11 are fixed to a plurality of fixing rods 210 having almost no heat conductivity described later by a plurality of fixing devices 220, preventing the outer box 11 and the inner box 13 from being connected to each other by the plurality of fixing devices 220, and preventing the upper plate 31 and the lower plate 33 of the lid 30 from being connected to each other by the plurality of fixing devices 220, thereby preventing the temperature of the asphalt concrete loaded in the asphalt concrete heat preservation box 1 from decreasing due to heat conduction of the asphalt concrete loaded inside the inner box 13 to the outer box 11 and the upper plate 31 of the lid 30.

[0197] On the outer surface of the inner box 13 and the inner surface of the upper plate 31 of the lid 30, a plurality of fixing brackets 200 for fixing a plurality of fixing rods 210 described later can be coupled. That is, in order to fixedly couple the plurality of fixing rods 210 described later, the plurality of fixing brackets 200 are formed on the outer surface of the inner box 13 and the inner surface of the upper plate 31 of the lid 30, and the plurality of fixing rods 210 are provided to prevent the aforementioned plurality of fixing devices 220 from directly connecting to the inner box 13 and the upper plate 31 of the lid 30.

[0198] The plurality of fixing brackets 200 can be formed in a shape in which the central portion is recessed inward. Therefore, the fixing rods 210 described later can be embedded and coupled in the recessed central portion.

[0199] The plurality of fixing brackets 200 can be formed of steel, and one surface of the fixing bracket 200 can be coupled to the outer surface of the inner box 13 or the inner side of the upper plate 31 of the lid 30 by a coupling means such as welding.

[0200] On multiple fixing frames 200, multiple fixing rods 210 can be respectively embedded and coupled. The multiple fixing rods 210 are respectively embedded and coupled to the multiple fixing frames 200, and at the same time, one end portions of multiple fixing devices 220 are respectively connected to the multiple fixing rods 210. That is, the multiple fixing rods 210 are respectively fixed to the multiple fixing frames 200 to block the multiple fixing devices 220 from directly contacting the upper plate 31 of the inner box 13 and the lid 30, and prevent the heat of the asphalt concrete loaded in the asphalt concrete heat preservation box 1 from being conducted to the outside through the multiple fixing devices 220, resulting in a decrease in the temperature of the asphalt concrete.

[0201] Such fixing rods 210 can be made of wood or MC nylon with almost no heat conductivity.

[0202] That is, by providing fixing rods 210 with almost no heat conductivity between the multiple fixing frames 200 and the multiple fixing devices 220, it is possible to prevent the heat of the asphalt concrete loaded inside the inner box 13 from being conducted to the outer box 11 or the upper plate 31 of the lid 30 by the multiple fixing devices 220.

[0203] Therefore, it is possible to prevent the heat of the asphalt concrete loaded inside the inner box 13 from being conducted through the multiple fixing devices 220 by the multiple fixing rods 210, resulting in a decrease in the temperature of the asphalt concrete.

[0204] For example, when the multiple fixing devices 220 are directly connected to the inner box 13, the heat of the asphalt concrete accommodated in the inner box 13 is conducted to the outer box 11 and the upper plate 31 of the lid 30 through the inner box 13 and the multiple fixing devices 220, which will be the main reason for the temperature of the asphalt concrete loaded in the asphalt concrete heat preservation box 1 to decrease in a short time.

[0205] Therefore, in order to prevent this situation, in the present invention, by respectively fixing one end portions of the multiple fixing devices 220 on the multiple fixing rods 210 with almost no heat conductivity, the multiple fixing devices 220 do not directly contact the inner box 13 and the upper plate 31 of the lid 30. Thus, not only is the outer box 11 stably fixed to the outside of the inner box 13, but also a separation space for filling the high-temperature heat insulation material 230 described later is formed between the outer box 11 and the inner box 13.

[0206] In the separation space between the outer box 11 and the inner box 13 and the separation space between the upper plate 31 and the lower plate 33 of the lid 30, a high-temperature heat insulation material 230 can be filled. When the high-temperature heat insulation material 230 is filled into the separation spaces between the outer box 11 and the inner box 13 and between the upper plate 31 and the lower plate 33 of the lid 30, it can prevent the heat of the asphalt concrete accommodated in the asphalt concrete heat preservation box 1 from being conducted to the outside.

[0207] This high-temperature heat insulation material 230 can be selected from ceramic wool, mineral wool, cellulose, ceramic paper, urethane, ceramic fiber, biocera kwool, and rock wool for use.

[0208] On the inner side surface of the outer box 11 and the upper side surface of the lower plate 33 of the cover 30, a heat insulation plate 250 can also be provided. The heat insulation plate 250 can use ceramic and silicon-based heat insulation plates such as ceramic plates, ceramic cloth, silicon plates, and silicon cloth.

[0209] The heat insulation plate 250 is respectively provided on the inner side surface of the outer box 11 and the upper side surface of the lower plate 33 of the cover 30. Thus, not only can the heat conduction of the asphalt concrete contained in the asphalt concrete heat preservation box 1 to the outer box 11 and the upper plate 31 of the cover 30 be efficiently blocked, but also the outside air conduction of the outer box 11 and the upper plate 31 of the cover 30 to the separated space between the outer box 11 and the inner box 13 and the separated space between the upper plate 31 and the lower plate 33 of the cover 30 can be efficiently blocked. That is, through the high-temperature heat insulation material 230 and the heat insulation plate 250, a heat insulation effect is formed in combination, thereby being able to more efficiently prevent the temperature of the asphalt concrete loaded in the inner box 13 from decreasing.

[0210] On the upper side of the separated space between the outer box 11 and the inner box 13, a heat insulation resin 240 can be provided. The heat insulation resin 240 is provided to finish the upper side of the separated space between the outer box 11 and the inner box 13. The heat insulation resin 240 prevents the outer box 11 from directly contacting the inner box 13 and the cover 30, more efficiently blocks heat conduction, and can prevent the temperature of the asphalt concrete from decreasing.

[0211] In addition, on the cover 30, a heat insulation resin 240 is also provided on the lower side of the lower plate 33, or the lower plate 33 of the cover 30 can be formed by the heat insulation resin 240. By providing the heat insulation resin 240 on the lower side of the cover 30, or forming the lower plate 33 of the cover 30 by the heat insulation resin 240, the heat insulation resin 240 provided on the upper side of the outer box 11 and the inner box 13 contacts the heat insulation resin 240 provided on the lower side of the cover 30 or contacts the lower plate 33 of the cover 30 formed by the heat insulation resin 240. Thus, the upper side of the outer box 11 and the inner box 13 and the cover 30 do not directly contact, thereby being able to more efficiently prevent the heat of the asphalt concrete from being conducted to the outside through the cover 30.

[0212] This heat insulation resin 240 can use a phenolic plastic plate or an MC nylon plate with excellent heat insulation effects.

[0213] On the upper side of the heat-insulating resin 240 provided on the upper side of the outer box 11 and the inner box 13 and on the lower side of the heat-insulating resin 240 provided on the lower side of the lid 30, cushion members 241 can be respectively provided, and the cushion members 241 can be provided only on the lower edge of the heat-insulating resin 240 provided on the lower side of the lid 30 or on the lower edge of the lower plate 33 of the lid 30 formed by the heat-insulating resin 240.

[0214] The cushion members 241 encapsulate the contact surfaces of the upper sides of the outer box 11 and the inner box 13 and the lid 30, thereby being able to efficiently prevent the heat of the asphalt concrete loaded inside the asphalt concrete heat preservation box 1 from dissipating to the outside.

[0215] Such cushion members 241 can use silicone foam, and as long as the material has a low thermal conductivity and high heat resistance, it can be used.

[0216] A moisture-proof agent can be applied to the inner surface of the outer box 11, the outer surface of the inner box 13, and the plurality of fixing frames 200 and the plurality of fixing rods 210, or the moisture-proof agent can also be applied to the inner surfaces of the upper plate 31 and the lower plate 33 of the lid 30 and the fixing frames 200 and the fixing rods 210 provided on the inner surface of the upper plate 31. In the separated space between the outer box 11 and the inner box 13 and in the separated space between the upper plate 31 and the lower plate 33 of the lid 30, the moisture-proof agent can prevent moisture from being generated due to the temperature difference between the outside air and the asphalt concrete.

[0217] The moisture-proof agent can be applied before filling the high-temperature heat-insulating material 230 in the separated space between the outer box 11 and the inner box 13 and in the separated space formed inside the lid 30.

[0218] As described above, by applying the moisture-proof agent to the inner surface of the outer box 11, the outer surface of the inner box 13, and the fixing frames 200 and the fixing rods 210, the heat conduction from the inner box 13 to the outer box 11 via the moisture generated in the separated space between the outer box 11 and the inner box 13 can be blocked; by applying the moisture-proof agent to the inner surfaces of the upper plate 31 and the lower plate 33 of the lid 30 and the fixing frames 200 and the fixing rods 210 provided on the inner surface of the upper plate 31, the heat conduction from the lower plate 33 of the lid 30 to the upper plate 31 via the moisture generated in the separated space between the upper plate 31 and the lower plate 33 of the lid 30 can be blocked.

[0219] In addition, it can also prevent the outer box 11, the inner box 13, the upper plate 31 of the lid 30, the lower plate 33, the plurality of fixing frames 200 and the plurality of fixing rods 210 from being eroded by moisture, and ensure the corrosion resistance of the asphalt concrete heat preservation box 1.

[0220] The moisture-proof agent can be manufactured through the following steps:

[0221] A step of adding 1 to 10 parts by weight of styrene-butadiene-styrene (SBS) to 100 parts by weight of insulating oil and heating and stirring to obtain a first mixture;

[0222] A step of adding 30 to 70 parts by weight of an asphalt compound to 100 parts by weight of a first mixture and then heating and stirring to obtain a second mixture;

[0223] A step of adding 1 to 5 parts by weight of polyaniline (PANI) to 100 parts by weight of the second mixture and then heating and stirring to obtain a third mixture;

[0224] A step of adding 6 to 12 parts by weight of zeolite to 100 parts by weight of the third mixture and then heating and stirring to obtain a fourth mixture;

[0225] A step of adding 1 to 5 parts by weight of polybutene and 0.2 to 0.8 parts by weight of polymethyl methacrylate (PMMA) to 100 parts by weight of the fourth mixture, and then naturally cooling after stirring to obtain a fifth mixture;

[0226] A step of adding 30 to 70 parts by weight of xylene to 100 parts by weight of the fifth mixture, and adding 10 to 40 parts by weight of Solvent No. 3 to 100 parts by weight of the fifth mixture and then dissolving to obtain a sixth mixture.

[0227] On the lower side of one side of the outer box 11 and the lower side of one side of the inner box 13, a discharge port 300 for communicating the outer box 11 and the inner box 13 can be formed. The discharge port 300 is a passage for discharging the asphalt concrete loaded inside the asphalt concrete heat preservation box 1 to the outside.

[0228] A heat-insulating resin 240 can be provided on the periphery and the outside of the discharge port 300. Thus, it is possible to prevent the outer surface of the discharge port 300 formed of a material with a high thermal conductivity from directly contacting the opening and closing door 310 described later, and thus it is possible to prevent the heat of the asphalt concrete from dissipating to the outside through the discharge port 300 and the opening and closing door 310.

[0229] On the discharge port 300, an opening and closing door 310 having the same structure as the lid 30 can be provided. On the upper side of the discharge port 300, the opening and closing door 310 can be rotatably coupled to the outside of the outer box 11 by a hinge.

[0230] In addition, the opening and closing door 310 can automatically open and close the discharge port 300 through an opening and closing power cylinder 312.

[0231] One side of the opening and closing power cylinder 312 can be coupled to the opening and closing door 310, and the other side can be coupled to the outer box 11.

[0232] Therefore, through the operation of the opening and closing power cylinder 312, the opening and closing door 310 closes or opens the discharge port 300, and thus it is possible to open and close the discharge port 300 through the opening and closing door 310.

[0233] This opening and closing power cylinder 312 can use a hydraulic cylinder or a pneumatic cylinder.

[0234] The opening and closing door 310 can be provided with a heat insulating resin 240 on the peripheral edge of the inner side surface in contact with the discharge port 300, or the heat insulating resin 240 can be provided on the inner side surface of the opening and closing door 310 in contact with the discharge port 300.

[0235] Therefore, the heat insulating resin 240 is provided on the discharge port 300 and the opening and closing door 310 respectively. Thus, the discharge port 300 and the opening and closing door 310 do not directly contact each other, thereby preventing heat conduction from the discharge port 300 to the opening and closing door 310.

[0236] In the opening and closing door 310, an auxiliary discharge port and an auxiliary opening and closing door 320 can also be formed. The auxiliary discharge port and the auxiliary opening and closing door 320 are formed to have a size smaller than that of the opening and closing door 310 and are used for the case of discharging a smaller amount of asphalt concrete than the amount discharged by the opening and closing door 310.

[0237] The auxiliary discharge port can be formed in the same shape as the discharge port 300, and the auxiliary opening and closing door 320 can be formed in the same shape as the opening and closing door 310.

[0238] An auxiliary opening and closing power cylinder 322 is provided on the auxiliary opening and closing door 320, so that the opening and closing of the auxiliary opening and closing door 320 can be adjusted. By forming the auxiliary discharge port and the auxiliary opening and closing door 320 in the opening and closing door 310, when a small amount of asphalt concrete is discharged from the asphalt concrete heat preservation box 1, less outside air flowing into the inside of the asphalt concrete heat preservation box 1 via the opening and closing door 310 can be made, thereby preventing the temperature of the asphalt concrete from decreasing.

[0239] This auxiliary opening and closing power cylinder 322, like the aforementioned opening and closing power cylinder 312, can use a hydraulic cylinder or a pneumatic cylinder.

[0240] In addition, in addition to being able to be opened and closed based on the auxiliary opening and closing power cylinder 322, an opening and closing operation device that can be manually opened and closed can also be provided on the auxiliary opening and closing door 320.

[0241] The opening and closing operation device is configured as a latch structure that enables an operator to manually operate the opening and closing of the auxiliary opening and closing door. Thus, it is possible to easily operate the opening and closing of the auxiliary opening and closing door even without the drive of the auxiliary opening and closing power cylinder 322.

[0242] In addition, the auxiliary discharge port and the auxiliary opening and closing door 320, like the discharge port 300 and the opening and closing door 310, can also be provided with the heat insulating resin 240 on the peripheral edge of the auxiliary discharge port and the peripheral edge of the inner side surface of the auxiliary opening and closing door 320.

[0243] That is, a heat-insulating resin 240 is provided on the peripheral edge of the inner side surface of the auxiliary opening / closing door 320 in contact with the auxiliary discharge port, thereby preventing direct contact between the auxiliary discharge port and the auxiliary opening / closing door 320, and further preventing the temperature of the asphalt concrete from being conducted to the outside through the auxiliary discharge port and the auxiliary opening / closing door 320.

[0244] In addition, a cushion member 241 may be provided on one side of the heat-insulating resin 240 provided on the peripheral edge of the discharge port 300, the peripheral edge of the inner side surface of the opening / closing door 310, the peripheral edge of the auxiliary discharge port, and the peripheral edge of the inner side surface of the auxiliary opening / closing door 320. Alternatively, the cushion member 241 may be provided only at the edge of the heat-insulating resin 240 provided on the peripheral edge of the inner side surface of the opening / closing door 310 and the peripheral edge of the inner side surface of the auxiliary opening / closing door 320.

[0245] The cushion member 241 encapsulates the contact surfaces between the discharge port 300 and the opening / closing door 310 and between the auxiliary discharge port and the auxiliary opening / closing door 320, thereby enabling more efficient prevention of the heat of the asphalt concrete loaded inside the asphalt concrete insulation box 1 from dissipating to the outside.

[0246] In order to handle the situation of loading the asphalt concrete insulation box 1 onto a general truck that is not a tipping truck and transporting the asphalt concrete to the construction site for discharge, a support plate 500 for supporting the asphalt concrete insulation box 1 may be further provided on the lower side of the outer box 11 of the asphalt concrete insulation box 1.

[0247] At this time, one end of the support plate 500 is joined to the lower side end of one side of the outer box 11 of the asphalt concrete insulation box 1 through a hinge. When the asphalt concrete insulation box 1 is raised or lowered by a lifting member 600 described later, the asphalt concrete insulation box 1 rotates based on the hinge connecting the outer box 11 and the support plate 500, so that the other side of the asphalt concrete insulation box 1 can be lifted and lowered.

[0248] Inside the separated space formed between the support plate 500 and the outer box 11, a lifting member 600 may be provided.

[0249] The lifting member 600 is formed by a hydraulic cylinder and a pneumatic cylinder, and is arranged such that the support plate 500 and the outer box 11 are joined to each other. The lifting member 600 is driven by the stretching and contraction of the hydraulic cylinder and the pneumatic cylinder to lift and lower the other side of the asphalt concrete insulation box 1.

[0250] Therefore, by driving the lifting member 600, the other side of the asphalt concrete insulation box 1 rises or falls, thereby enabling the asphalt concrete loaded in the asphalt concrete insulation box 1 to be easily discharged through the discharge port 300.

[0251] In addition, as another method of loading the asphalt concrete insulation box 1 onto a general truck that is not a tipping truck and transporting it to the construction site for discharge, there is a discharge method based on a screw 400 formed inside the inner box 13.

[0252] To this end, a screw 400 may be formed along the length direction toward the discharge port 300 at the central part of the lower side inside the inner box 13.

[0253] The screw 400 is formed to be rotatable along the length direction from one end inside the inner box 13 toward the discharge port 300.

[0254] By rotating such a screw 400, the asphalt concrete loaded inside the inner box 13 can be discharged to the outside through the discharge port 300.

[0255] That is, when the asphalt concrete heat preservation box 1 is mounted on a general truck that is not a tipping truck, even when the lifting member 600 is not provided at the lower part of the asphalt concrete heat preservation box 1, by rotating the screw 400 provided inside the inner box 13, the asphalt concrete loaded inside the inner box 13 is moved toward the discharge port 300, whereby the asphalt concrete can be easily discharged to the outside.

[0256] In addition, a weight measurement sensor may be formed at the lower part outside the outer box 11. Since the weight measurement sensor measures the overall weight of the asphalt concrete heat preservation box 1, the loading amount of the asphalt concrete can be grasped based on the weight measurement values that vary with the loading amount of the asphalt concrete.

[0257] As the weight measurement sensor, generally used pressure measuring elements, hydraulic sensors, and weight sensors can be used.

[0258] Reference Figures 14 to 16 , the asphalt concrete heat preservation box according to an example of the present invention can be mounted on the loading part of a vehicle such as a truck. That is, in order to move the asphalt concrete heat preservation box 1 to the construction site, after the asphalt concrete heat preservation box 1 is mounted on the truck by using a lifting device or a crane, etc., the asphalt concrete heat preservation box 1 can be fixed by a fixing device or the like.

[0259] Therefore, by mounting and fixing the asphalt concrete heat preservation box 1 on the truck, it is possible to transport the asphalt concrete from the asphalt concrete manufacturing factory to the construction site.

[0260] When the asphalt concrete heat preservation box 1 of the present application invention is used by mounting it on a tipping truck, the asphalt concrete heat preservation box 1 without the support plate 500, the lifting member 600, and the screw 400 is mounted, so that the discharge of the asphalt concrete is made easier by the lifting device of the tipping truck.

[0261] In addition, when the asphalt concrete insulation box 1 of the present invention is mounted on a general truck of a non-tipping truck, the asphalt concrete insulation box 1 provided with a support plate 500 and a lifting member 600 is mounted in the asphalt concrete insulation box 1, or the asphalt concrete insulation box 1 provided with a screw 400 is mounted inside the asphalt concrete insulation box 1, thereby facilitating the discharge of asphalt concrete.

[0262] The present invention is not limited to the above-described embodiments. Not only is its application range diverse, but also various modified embodiments can be implemented without departing from the gist of the present invention claimed in the claims.
