Description

[0001] MOVABLE DEVICE FOR STORAGING AND KEEPING WARM OF ASCON [0002]

More particularly, the present invention relates to a portable asphalt heat insulating storage device. More particularly, the present invention relates to a portable asphalt heat insulating storage device, To a portable aspheric heat insulating storage device.

Generally, asphlt concrete (hereinafter referred to as 'ascon') used in roads is a solid or semi-solid material of black, and a solid component called asphalten is dispersed in an oil component called martin.

The above-mentioned ascon is used for road paving, airport paving, waterproofing for packaging or building according to the kind of the above. Especially, asphalt for road pavement is mixed with aggregate such as sand and gravel, which is called ascon or asphalt concrete.

The general facility for manufacturing such an ascon is to transfer the aggregate fed from the aggregate containing the aggregate to the inside of the dryer through the belt, and then heat the aggregate filled in the dryer through the oil burner. Dust and noxious gases generated while being burned by the oil burner are discharged to the outside through the air discharge device and the dust collecting device. Also, the aggregates heated in the dryer are moved to the screen by the elevator for conveyance, and classified into sizes on the screen. Then, the aggregates are moved down to the mixer, and the thus produced ascon is conveyed to the ascon conveying It is filled in the vehicle and then moved to the site.

The temperature of the ascon is increased from about 40 ° to 50 ° and then moved to the site. However, the temperature of the ascon is gradually lowered as the time for moving the ascon to the site and the time for working on the site elapses, and the temperature of the ascon, which is used for road pavement or airport pavement, °.

Therefore, when using the ascon which is significantly lowered at the road pavement site, there is a problem that it is required to further planarize the ascon which has been lowered on the floor with the mixer. In addition, it is very disadvantageous to use the ascon which is lower in temperature when repairing a damaged portion of a part of a road that has already been packaged, or when performing a packing operation around the buried manhole. Particularly, in the case of the packaging work reinforcing the perimeter of the manhole, the working time has passed since a considerable time has elapsed since it is embedded at a constant interval over several kilometers.

As time elapses in the maintenance / reinforcement work of the road for a long time, a part of the ascon which is lowered in temperature is hardened. Therefore, it is not possible to use hardened ascon in the field where the working time has elapsed, and when there is a small amount of hardened ascon, the problem of environmental pollution that is thrown to one side of the road has been accompanied.

In the past, when a truck carrying an ascon was replaced with a dump truck, when the ascon stored in the truck is shipped from a field work, a predetermined amount is taken out by an excavator (aka "crane"), It was shipped. Because of this, it takes a lot of time and requires a lot of workers.

However, the hot air generated by the heater portion directly contacts the ascon by the flow path, thereby heating the ascon. Thus, the oil component of the ascon is melted and the liquid substance is discharged through the outlet for discharging the ascon. .

In addition, the flow path is formed on the bottom surface and the side surface of the loading portion in which the ascon is housed. That is, the flow path can not be formed in the switch for opening and closing the upper portion of the accommodating portion, so that the portion where the hot air is discharged can be installed at the upper portion of the accommodating portion.

In addition to the above problems, the heater was continuously operated during the movement of the portable as-built storage device to the site, and was exposed to the danger of overheating due to overload and overheating.

Meanwhile, it is preferable that the heating unit 50 is located at a front portion of the loading unit 10. However, it may be installed in the vehicle in a state of being spaced apart from the loading unit 10. The heating unit 50 is for supplying hot air to the flow path, and is driven by a battery or fuel of the vehicle. Since the heating unit 50 is widely used in the mechanical industry, a detailed description thereof will be omitted. However, the heating unit 50 is provided with a separate blowing fan to supply generated hot air to the flow path.

The loading unit 10 further includes a sensor unit and a control unit. The sensor unit senses the horizontal inclination of the receiving unit 20 with respect to the ground. The control unit controls the operation of the heating unit 50 when a predetermined slope is exceeded according to the horizontal state sensed by the sensor unit.

The use state of the portable asphalt heat storage device of the present invention as described above will be described as follows.

First, the mobile asphalt heat storage device is moved to a site such as a manhole work, a manhole repair work, or a part of a road repair work after receiving the asphalt (A) from the asphalt manufacturing device, .

The automatic lid unit 30 provided in the loading unit 10 is opened to receive the asphalt A from the accommodating unit 20 when the asphalt A is supplied from the apparatus. That is, the automatic lid unit 30 is operated by the first and second driving cylinders provided in front of the loading unit 10 to open or close the upper portion of the receiving unit 20. [

In order to open the first and second automatic lids 30a and 30b, when the operator operates the first and second driving cylinders, the cylinders are fixed in the loading unit 10, The piston rod is operated. At this time, since the pair of piston rods are hinged to the front portions of the first automatic lid unit 30a and the second automatic lid unit 30b, respectively, the first and second automatic lid units 30a And 30b are opened to both sides of the accommodating portion 20, respectively.

In this state, it is possible to load the asphalt (A) falling from the asphalt producing apparatus into the accommodating section (20). Here, the heating unit 50 is driven only in a state in which the aspheric A is supplied from the asphalt production apparatus, that is, the upper portion of the accommodating unit 20 is closed so that the temperature inside the accommodating unit 20 Is adjusted to be similar to the temperature of the aforementioned Ascon (A).

This is because, when the accommodating portion 20 is supplied with the high-temperature asphalt A at a low temperature, the asphalt A sticks to the inner surface of the accommodating portion 20 and becomes hard. Therefore, it is preferable that the inside temperature of the accommodating unit 20 is adjusted to a height similar to the temperature of the ascon A before the ascon A is supplied, and then the ascon A is supplied. The temperature of the accommodating portion 20 is adjusted by the heating portion 50 described later.

The first and second automatic lids 30a and 30b are driven to close the upper portion of the accommodating portion 20 when the loading of the asphalt A in the accommodating portion 20 is completed. The heating unit 50 is driven to maintain the internal temperature of the accommodating unit 20. This is for keeping the temperature of the ascender A constant and moving it to the construction site.

First, the hot air generated by the operator driving the heating unit 50 is supplied to the first flow path 21 formed in the receiving unit 20 through the blowing fan provided in the heating unit 50. Since the first flow path 21 is formed between the inner and outer surfaces of the accommodating portion 20, the accommodating portion 20 can be maintained at a height similar to the temperature of the Ascon A '. The first flow path 21 communicates with the second flow path 31 provided in the first and second automatic lid sections 30a and 30b so that a hot airflow .

The hole 22 provided at the upper end of the accommodating portion 20 communicates with the connection hole 32 provided at the portion connected to the first and second automatic lids 30a and 30b, And is communicated only when the first and second automatic lids 30a and 30b close the receptacle 20. That is, when the first and second automatic lids 30a and 30b are opened, the projecting portion 33 closes the hole 22 so that the first flow path 21 and the second flow path 31 are closed, Is not communicated.

The hot air is discharged to the outside through the hot air outlets 34a and 34b formed on the upper surfaces of the first and second automatic lids 30a and 30b through the first flow path 21 and the second flow path 31. [ The overload of the heating unit 50 can be prevented. This is for automatically controlling the operation of the heating unit 50 when the ascon A is supplied from the ascon manufacturing apparatus.

That is, when the first and second automatic lid units 30a and 30b open the receiving unit 20, the operation of the heating unit 50 is stopped and the first and second automatic lid units 30a, and 30b close the receiving portion 20, the heating portion 50 is operated. Such driving may be realized by sensing the sensor by installing the sensor on the first and second automatic lids 30a and 30b.

In this state, the driver moves the portable asphalt heat storage device of the present invention to the site. At this time, the above-described heating unit 50 performs a continuous operation to keep the temperature of the ascender A constant.

Here, the operation of the heating unit 50 is automatically controlled when the driver passes the slope when driving the vehicle, that is, when the horizontal state of the accommodation unit 20 deviates from a predetermined inclination value. This is to prevent a fire from being generated due to overload and overheating of the heating unit 50.

When the vehicle passes the horizontal road again, the heating unit 50 is operated again to supply the hot air to the inside of the accommodating unit 20.

Thereafter, when the portable asphalt heat insulating storage device arrives at the site, the elevation part 60 is driven to raise the front part of the loading part 10 upward. At this time, a large amount of the asphalt (A) is discharged through the discharge lid part (40) provided behind the loading part (10).

The operation of the automatic lid 30, the elevation portion 60, the heating portion 50, and the like described above can be performed by the operation portion provided on the side of the loading portion 10 or the rear portion thereof.

Meanwhile, although not shown in the accompanying drawings, the movable asphalt heat storage device of the present invention can be used for snow-removing snow piled up on the road in winter.
