Description

[0001] Lane drying device [

More particularly, the present invention relates to a lane drying apparatus for a vehicle, and more particularly, to a lane drying apparatus for a vehicle, which is configured to store waste dry air that is scattered after being used for lane drying to be reused for lane drying to improve energy efficiency and drying speed, The present invention relates to a vehicle lane drying apparatus capable of flexibly coping with a road surface state by a mutually complementary height adjustment structure to more securely isolate a paint lane from an external environment.

In general, the lane paint is a mixture of one type (room temperature type), three types (heating type), two kinds using water paint (water soluble), four kinds of powder type (fusion type) 5 types (room temperature curing type), and the paint is selectively used according to the road location climate environment.

However, since 2014, interest in environmentally friendly paint has increased, and the second paint with low volatile organic compound (VOC) content has been applied to the second paint. However, due to its physical properties, it has a long drying time and is sensitive to temperature. The drawback was that the quality of painting was greatly influenced by the weather change.

In addition, the applicant, Korea Highway Corporation, carries out a lane painting operation for several hundred km of roads every year, and controls the traffic for a certain distance and a certain time by using a lavicon for drying after lane painting. For example, As shown in FIGS. 12 to 14, the operation method is to set a distance of 1,200 to 1,700 m in a control zone required for lane drying using a laser on a highway, and the installation and retrieval of the laser is dependent on manual operation. The number of deaths incurred each year increases, and a lot of manpower, time, and expenses are wasted as shown in [Table 1] below. If the cost is calculated based on the national road network as shown in [Table 2] It costs 56.8 billion won.

[Table 1. Cost calculation of lane-painting input]

[Table 2. National road network standard input cost conversion]

Particularly, as many vehicles (three painting vehicles, two sign cars, one VMS vehicle) used in the lane painting operation are moving at a low speed by using the road of 2.5 km, the simulation analysis result of [Table 3] , Traffic accidents are serious, and traffic fatal accidents are increasing due to vehicles crossing the line of work vehicles in the main entrance and exit sections (minutes and merging sections). (Simulation analysis result made by NEOTTIS Co., Ltd. at the request of Daegu Gyeongbuk General Manager of Korea Highway Corporation)

[Table 3: Traffic Acceleration Simulation Results for Current 2.5Km Land Use]

According to the results of the simulation analysis, the current lane-painting operation method is inevitable because it requires a long working space of about 2.5 km, which leads to a long time of main landing and congestion and a risk of a traffic accident during the work process , It is urgent to improve painting work.

In view of this, in the conventionally disclosed Patent Registration No. 10-1050507, a resin solution in which a solid acrylic resin is dissolved in an acrylic monomer is included in a total amount of 20 to 40 parts by weight based on the total weight of the composition, A technology for highly environmentally friendly paints which is excellent in adhesion and visibility, water resistance, abrasion resistance, weather resistance, alkali resistance, chemical resistance and durability as well as ingredients which are harmful to environment such as thinner or gasoline has been preliminarily registered .

However, in the above conventional art, there is a technique for increasing the quality of paint using changes in the physical properties of paints. In the case of painting a lane, three paint cars, two sign cars, The traffic is controlled at a speed of 5km / hr while the traffic control is performed at 1.700m. As a result, the traffic congestion increases and the traffic control of the main line entrance / exit section (minute and merging section) There was a problem that large traffic accidents and lanes that could not be built were damaged.

In addition, in order to control traffic in the work area of about 1,200 to 1,700 meters, the first vehicle installed in the first vehicle and the rear vehicle in the method of retrieving the first vehicle, As additional space has to be secured, the costs are rising.

In addition, in the Utility Model Registration No. 20-288099, there is provided a lane marking machine installed at the rear of the reflector application unit and provided with a thermal jet opening for ejecting the heat generated from the heating unit to the road surface, thereby quickly drying the paint sprayed on the road surface Have been registered in advance.

However, since the conventional technique is a technique for rapidly drying paint using heat, it is difficult to expect high energy efficiency due to the characteristic of a one-time drying structure in which heat is ejected and then disappears into the air. In particular, It is difficult to expect a lane drying effect because the lane drying time is less than 1 second when mounted on a vehicle.

Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a liquefied natural gas Which is capable of flexibly coping with the road surface state and thereby more securely isolating the paint lane from the outside environment by the mutually complementary height adjustment structure of the vehicle lane drying apparatus.

In order to achieve the above object, a feature of the present invention is that a nozzle (21) which is mounted on a vehicle (1) and is formed so as to extend in a running direction and which primarily dries the lane by spraying dry air is provided, A main body 100 having a drying chamber 10 for keeping the lane separated while protecting the liquefied dry air to be used for secondary lane drying; An extended drying room (16) connected to the drying room (10) and extended in the lane - length direction and sharing the dry air stored in the drying room (10) for tertiary lunar drying to isolate and protect the lane; And the main body 100 are mounted on the vehicle 1 so that the height of the main body 100 and the extended drying chamber 16 are controlled by the height of the main body 100, And a height adjustment unit that is provided to adjust the height in a complementary manner.

At this time, the nozzle 21 is connected to the dry air supply unit 20 installed in the main body 100, and the dry air supply unit 20 is connected to the drying chamber 10 by a separation space 15, .

The air inlet 20a of the drying air supply unit 20 is controlled by the valve B so as to be selectively connected to the outside of the main body 100 or the inside of the drying chamber 10.

The extended drying chamber 16 is provided with a drying air outlet 16a formed on one side wall corresponding to the longitudinal direction and is opened and closed by a lid 16b.

The main body 100 is detachably attached to the vehicle 1 by means of the joint portion 11. [

In addition, the main body 100 is vertically adjustable by a road surface sensing unit 12 including a sensor, a wheel, and a sliding plate, so that the distance between the main body 100 and the road surface is maintained constant.

In addition, the blocking film 13 is arranged to be positioned in a direction opposite to the up-and-down direction of the main body 100 by the control unit.

The shielding film 13 is formed of a corrugated sheet, and is adapted to expand the deformation width per length corresponding to the irregular road surface.

In addition, the drying chamber 10 is provided so that the side plate 14 is installed to be adjustable in angle, and the width of the road surface exposed to the dry air is controlled.

Further, it is characterized in that the space inside the drying chamber (10) is expanded or reduced by moving the diaphragm (15) up and down.

The extended drying chamber 16 is installed in the drying chamber 10 so as to extend to one side or both sides of the drying chamber 10.

The main body 100 is provided at the front, rear, front, and rear of the paint injection nozzle 2 of the lane-painting vehicle 1.

In addition, the dry air supply unit 20 is provided at at least one place, and hot air or natural air is selectively supplied according to whether the heater 22 is operated or not.

In addition, the dry air supplied through the nozzle 21 is injected backward at an angle of 40 to 60 degrees with respect to the road surface by the inclined duct 24.

The dry air supply unit 20 is selectively connected to a duct 26 for recovering and supplying waste heat generated in the vehicle 1. [

According to the present invention, the waste drying air, which is primarily used for lane drying through the nozzle and then scattered, is stored in the drying chamber and the extended drying chamber to be reused for second and third lane drying, And the drying speed is remarkably shortened, which is suitable for mounting on a vehicle. Particularly, by adjusting the height of the main body and the shielding film to each other, the road surface including the overspeed preventing jaw and the gradient can be flexibly handled, There is an effect that the lane is more securely isolated from the outside environment.

In addition, since the paint is forcedly dried during the road lane painting operation to shorten the traffic control section, it prevents the traffic accident and lane damage caused by the traffic crossing vehicle and the intersection of the work section, and especially, .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a lane drying apparatus for a vehicle, wherein the lane drying apparatus for a vehicle is configured to store waste dry air that is scattered after being used for lane drying and reused for lane drying to improve energy efficiency and drying speed, The drying chamber 10, the barrier film 13, the extended drying chamber 16 (the drying chamber 10), the barrier film 13, and the extended drying chamber 16 And a nozzle 21, as shown in Fig.

The main body 100 according to the present invention is mounted on the vehicle 1 and is extended in the running direction and has nozzles 21 for primarily drying lanes by spraying dry air therein, There is provided a drying chamber 10 for isolating and protecting the lane while keeping the dried air that has been used after being used for secondary lane drying. The main body 100 is provided so as to be detachably mounted on at least one vehicle 1 of a painting vehicle, a material vehicle, and a sign vehicle used for lane-painting, as shown in Figs. 1 and 3, .

At this time, the main body 100 is provided with a drying chamber 10 and a nozzle 21 in a state where a bottom surface corresponding to the road surface is open, wherein the nozzle 21 is provided with dry air supplied through the dry air supply unit The drying chamber 10 serves to store and store dry air that is primarily used for lane drying and then scattered to the air so as to be dispersed into the air.

As shown in FIG. 2, since the drying chamber 10 is formed in a rectangular shape as shown in FIG. 2, the drying time of the drying chamber 10 expands in proportion to the inner space extension length, and is 5 to 10 km / h , The lane is exposed to the dry air for 5 to 10 seconds to maintain the excellent drying efficiency during driving. In particular, the lane has a structure in which the lane is primarily heated directly by the dry air injected through the nozzle 21, and then dried secondarily by the internal temperature of the isolated drying chamber 10, Are improved together.

In addition, since the lane is isolated and protected inside the drying chamber 10 during drying, the lane color quality is improved without being influenced by the external environment including temperature difference, snow, rain, dust, foreign matter, etc., .

The main body 100 is provided on the front or rear of the paint spray nozzle 2 of the lane painting vehicle 1 or on the front and rear sides as shown in Fig. 10, and depending on the installation position of the main body 100, The front surface of the lid 2 is preheated, washed, and dried in the front of the vehicle.

The extended drying chamber 16 according to the present invention is connected to the drying chamber 10 and extends in the longitudinal direction of the lane and shares the dry air stored in the drying chamber 10 and is used for tertiary lane drying to protect the lane . The extended drying chamber 16 is installed in a drawer from the inside of the drying chamber 10 by rails so that the extended drying chamber 16 is inserted so as not to interfere with the running, And extend in the longitudinal direction to enlarge the lane drying and isolation protection areas.

The extended drying chamber 16 is connected to the drying chamber 10 to form a tunnel-shaped dry air storage space. Accordingly, the time during which the lane is exposed to the dry air is 50 to 100% of the exposure time by the drying chamber 10, It has the advantage of extending the speed of the vehicle by 30 ~ 60% compared with the existing speed, and it has the advantage that the lane is dried more quickly even under the harsh climatic conditions such as cold winter and cloudy weather.

Here, the extended drying chamber 16 is provided to extend to one side of the drying chamber 10 as shown in FIGS. 1 and 3 or both sides as shown in FIG. 1, the dry air injected through the nozzle 21 is moved in a direction opposite to the running direction of the vehicle by the running speed of the vehicle, Therefore, at this time, the extended drying chamber 16 holds waste dry air in the rear of the drying chamber and is used for tertiary drying of the lane.

On the other hand, as the expansion and contraction size of the dry air storage space is adjusted by the extended drying chamber 16 and the time for exposing the lane to the dry air is proportional to the expansion and contraction size, the paint having a short drying time at the same traveling speed, The extension time of the extended drying chamber 16 is shortened to shorten the exposure time to the dry air and the extended drying chamber 16 is expanded in the case of the severe weather conditions such as cold winter and cloudy weather, And the drying efficiency is improved. As a result, the expansion and contraction adjustment structure of the extended drying chamber 16 has an advantage in that the time during which the lane is exposed to the dry air can be easily controlled according to the environmental factors including temperature and weather and the type of paint.

The main body 100 is mounted on the vehicle 1 so that the height of the main body 100 is adjusted up and down and the height of the main body 100 is adjusted by adjusting the height of the main body 100 in accordance with the height of the main body 100. The main body 100 and the shielding film 13 are vertically and horizontally adjusted by adjusting means including a cylinder and a spindle. At this time, the main body 100 has a protruding height of the structure including the road surface state of the lane marking section, And the height of the shielding film 13 is adjusted so as to close between the road surface and the bottom surface of the main body 100 after the height setting of the main body 100 is completed.
A shielding film 13 is provided under the extended drying chamber 16 to close the road surface and the shielding film 13 is the same as the shielding film 13 provided in the main body 100, So that the height of the main body 100 can be adjusted.

At this time, the shielding film 13 provided in the main body and the extended drying chamber 16 is conveyed by the control unit in a direction opposite to the up-and-down direction of the main body 100 so as to close between the road surfaces. When the main body 100 is conveyed upward to pass the protruding jaws of an unexpected height during the lane drying operation after the initial setting of the main body 100 and the shielding film 13, The shielding film 13 is transported in a downward direction opposite to the transport direction of the main body 100 to close the gap between the road surfaces to finish the gap between the road surfaces.
On the other hand, the barrier film 13 is formed in a flexible structure such as rubber, silicone, or mohair so as to smoothly close the road surfaces while being flexibly bent when passing through the road surface overcrowding step, or the barrier film 13 is formed of a corrugated plate , And it is preferable that the deformation width is extended corresponding to the irregular road surface.

The space between the bottom surface of the main body 100 and the road surface is tightly closed by flexibly adjusting the height of the main body 100 and the barrier 13 by adjusting the height of the main body 100, The external loss of the dried dry air is more tightly blocked, thereby improving the drying efficiency and blocking the introduction of foreign matter, thereby improving the quality of painting. (In FIG. 6, the blocking film 13 is formed in the form of a rubber plate on both sides of the drying chamber 10)

At this time, the nozzle 21 is connected to the dry air supply unit 20 installed in the main body 100, and the dry air supply unit 20 is connected to the drying chamber 10 by a separation space 15, Respectively. The diaphragm 15 is formed as a horizontal plate so as to divide the inner space of the main body 100 into upper and lower spaces. The drying space 10 is formed in the lower space and the space for installing the dry air supply unit 20 is secured in the upper space.

As the internal space of the main body 100 is divided by the diaphragm 15 to secure the drying chamber 10, the drying air loss due to the unnecessary space inside the drying chamber 10 is prevented, .

In FIG. 11, the dry air supply unit 20 is provided with two hot air blowers that generate dry air at high temperature. However, the present invention is not limited to this, and a blower fan may be installed in the dry air supply unit 20 It is also preferable that the nozzle 21 is installed at the front and the center of the drying chamber 10, respectively.

At this time, the drying air supply unit 20 is provided at at least one place, and hot air or natural air is selectively supplied by the operation of the heater 22. [ The heater 22 is provided to be turned on / off by a switch or a control unit, and heats the air conveyed through the dry air supply unit 20 to supply hot air.

When the drying air supply unit 20 is provided at at least two locations, the operation of the heater 22 is selectively controlled. For example, when the heater 22 of the dry air supply unit 20 located at the front side is turned on, And the heater 22 of the dry air supply unit 20 located at the rear side is turned off to use the heated lane in a dry manner. When the heater 22 installed in each dry air supply unit 20 is operated independently, it is preferable that the internal space of the drying chamber is partitioned and operated.

In addition, the dry air supplied through the nozzles 21 is injected backward at an angle of 40 to 60 degrees with respect to the road surface by the inclined ducts 24. 2, the inclined duct 24 is configured to spray the dry air injected through the nozzle 21 at a slanting angle in a direction opposite to the running direction of the vehicle so that the dry air strikes the surface of the painted lane at an oblique angle, And the air scattered after directly drying the paint lane is quickly transferred to the inside of the drying chamber and the inside of the extended drying chamber to be used as the second and third drying air.

The dry air supply unit 20 is provided to selectively communicate with a duct 26 that collects and supplies waste heat generated in the vehicle 1. [ 13 (b), one end of the duct 26 is connected to the dry air supply unit 20 and is opened and closed by a valve. The other end of the duct 26 is connected to the heating unit of the engine including the heater of the vehicle, So that the generated waste heat is recovered.

Accordingly, when the lane painting operation is performed in winter, the waste heat is recovered through the duct 26, or the waste heat is reheated by the heater 22 to be used as hot air, thereby improving the energy efficiency.

On the other hand, the dry air supplied through the dry air supply unit 20 is provided to adjust the wind direction by the wind direction plate 23. 12 (a), the wind direction plate 23 is provided at a position corresponding to the jet port of the dry air supply unit 20 and is swiveled by the lever to adjust the wind direction, or the dry air supply unit 20, It is preferable that a perforated plate is provided in the lateral direction at the lower portion so that the dry air is uniformly sprayed throughout the perforation.

One side of the valve B is connected to the outside of the main body 100 and the other side of the valve B is connected to the outside of the drying chamber 10 through the air inlet 20a of the drying air supply unit 20. [ So that the outside air of the main body 100 or the air inside the drying chamber 10 can be selectively introduced by the control of the valve (B). As shown in FIG. 13 (a), the valve B is formed as a three-way valve, one side of which is connected to the outside of the main body 100 to suck the outside air and the other side is connected to the inside of the drying chamber 10, The suction air for absorbing the waste drying air is connected to the rear of the drying chamber 10 or to the rear of the extended drying chamber 16. In this case, desirable.

Accordingly, during the winter season when the temperature difference between the inside and the outside of the drying chamber 10 is greatly increased, the inside of the drying chamber 10 is circulated and heated by controlling the valve B so that the dry air is heated quickly. When the humidity is high, the valve B is switched to suck and supply the outside air, so that the drying speed is improved.

The extended drying chamber 16 is provided with a dry air outlet 16a on one side wall corresponding to the longitudinal direction and is opened and closed by a lid 16b. The amount of the dry air stored in the tunnel-shaped space including the drying chamber 10 and the extended drying chamber 16 is adjusted by the lid 16b through the discharge port 16a, When the humidity inside the extended drying chamber 16 is high, the cover 16b is opened to adjust the amount of dry air discharged through the discharge port 16a, thereby maintaining the optimum drying speed for each situation.

At this time, the main body 100 is detachably attached to the vehicle 1 by means of the joint portion 11. 4, the joint unit 11 is a frame that connects the main body 100 and the vehicle 1 and is formed as a stretchable structure so as to adjust the distance between the vehicle 1 and the main body 100 and to adjust the height of the main body 100 Respectively.

Here, the end of the joint portion 11 is provided to be easily detachable and attachable to the vehicle 1 by means of a fixing means including a clamp and a bolt, and can be easily installed without deforming the existing vehicle do.

Also, the main body 100 is elevated and lowered by a road surface sensing unit 12 including a sensor, a wheel, and a sliding plate to maintain a constant distance from the road surface. 5 (a) shows a configuration in which a sensor is provided on the bottom surface of the main body 100, the sensor detects the road surface, and the driving unit is operated through the control unit to adjust the vertical height of the main body 100, 5 (c) show a state in which the main body 100 is mounted on the railway car in a vertical direction while rails are mounted on the railway car, and a wheel and a sliding plate, which are carried on the road surface, are installed on one side of the main body 100.

Since the height of the main body 100 is controlled by the road surface sensing unit 12 including the sensor, the wheels and the sliding plate during the movement of the vehicle 1, the constant distance to the road surface is maintained, And the drying efficiency is prevented from being lowered due to the increase in the distance of the impact.

In the drying chamber 10, the width of the road surface where the side plate 14 is installed to be adjustable in angle and is exposed to the dry air is controlled. The side plate 14 is installed in the drying chamber 10 separately as shown in FIG. 7 (a) so as to be pivoted about the hinge or as a side plate 14 using the side wall of the drying chamber 10 as shown in FIG. 7 (b) As shown in FIG.

Accordingly, as the lower opening width of the drying chamber 10 is varied by adjusting the inclination angle of the side plate 14, the dry air injection width is adjusted corresponding to the painted lane width, thereby preventing loss of dry air, So that the drying efficiency is improved.

In addition, the drying chamber 10 is provided to expand or contract the internal space 10a by a partition plate 15 installed to move up and down. The diaphragm 15 is installed in the lateral direction as shown in FIG. 8, and the vertical position of the diaphragm 15 is adjusted by rails so that the vertical width of the inner space of the drying chamber 10 is expanded or reduced.

Accordingly, when the interior space of the drying chamber 10 where the diaphragm 15 rises and the dry air is stored is expanded, the drying air capacity is increased in the drying chamber 10 to prevent the drying efficiency from lowering even if the color speed is increased. 15 is lowered and the capacity of the drying air is reduced when the internal space of the drying chamber 10 is reduced so that the drying operation can be performed even if the dry air supply unit 20 is applied at a low capacity.

In this way, since the lane is painted and the forced drying and the lane painted road surface are preheated, the lane is quickly dried compared with the current working method, and the traffic control section is shortened to 100 m to 400 m as shown in Fig. 14, In the same way, it is possible to prevent the traffic accident accident caused by the vehicle crossing the work section in the main entrance and exit part of the current operation method and to prevent the lane damage, and to improve the workability and the painting quality without being influenced by the climatic conditions including the cloudy day and winter .

In addition, the labor required for operating the lacquerware is reduced in the lane painting operation, and the area of the painting per hour is enlarged. As shown in Fig. 16, the cost is reduced by 10 to 15% per ㎡ compared to the current working method.

Therefore, as shown in [Table 4] below, when the lane painting operation is carried out, the road distance is reduced by 70 ~ 80% compared to the current 2.5 km, and the stagnation duration is 171.7 minutes To 123.3 minutes. (Simulation analysis result made by NEOTTIS Co., Ltd. at the request of Daegu Gyeongbuk General Manager of Korea Highway Corporation)

[Table 4] Traffic Loss Simulation Analysis Results for 0.4 Km Location

[Table 5: Analysis of improvement effects when applying the present method]

As a result, the existing lane-painting work method has a problem of long work space occupation of about 2.5 km, which leads to problems such as main land, long dead-time, risk of traffic accidents during work process, , It requires only a short work space of 0.4 km, which has the effect of reducing the congestion on the highway main line. As a result of analysis of the improvement effect, average travel time decreased by 30.9%, total delay time decreased by 45.5% and stagnation duration decreased by 28.2% as shown in [Table 6].
