SUMMARY OF THE INVENTION It is an object of the present invention to provide a method and apparatus for preventing the road from being damaged by a concentrated load even when the road surface is free of ice sheets, Roll.

As shown in FIG. 2, the roll has a layer in which a hydraulic pressure is formed. The visibility of the crushing roll is protruded or depressed by utilizing the elasticity of the hydraulic pressure and the spring. If necessary, The height of the visible light can be controlled. With this configuration, damage to the road can be minimized even when the road surface is free of ice sheets.

Another object of the present invention is to use an array of one-shaped blades, which is formed on a roll and breaks the ice sheet, differently from the conventional one. This arrangement breaks down the ice sheet in the form of a quadrangle. The inside of the blade forms an empty space to prevent the accumulation of ice on the blade by the rotation of the roll, and it is possible to reduce ice accumulated on the blade by applying non-hydrophilic material such as oil and paraffin to the blade surface. It is also a way to more aggressively form grooves in the rollers and feed oil and paraffin to the blade. It is also possible to control the degree of protrusion of the blade by using the oil pressure by connecting the inside of the blade with the oil pressure portion. In order to control the protrusion of the blade, a spring is attached to the blade so that the blade can be fixed to the inside of the groove of the roller when the hydraulic pressure is removed.

It is another object of the present invention to provide a method of controlling visibility or a blade capable of controlling the protrusion height by adjusting the hydraulic pressure to prevent breakage of the road. Generally, the more ice on the road, the greater the amount of crushed ice that can be expected to occur. If the amount of ice crushing is small and there is a high level of protrusion of many visible or blades, the risk of road breakage is high. And a method of controlling the height of protrusion using a hydraulic device by calculating the amount of ice collected in the collecting device.

Another object of the present invention is to crush ice only physically using the shape of the roll, the weight of an appropriate roll, and the hydraulic cylinder attached to the vehicle, and adjusting the arm portion connected to the roll to hydraulic pressure, To minimize road damage, reduce material costs, and save energy. To do this, we recognize the state of road surface using laser and use this measured value for control.

The ice sheet removal vehicle caused by snow in winter according to the present invention proposes two types of rolls for removing ice sheets on roads where there is a great deal of movement of ice sheets and people on roads where a lot of vehicles move,

In the case of a road surface where a lot of people are moving, a conventional roll having a large number of existing visors is used. The visibility of the road surface can be protruded or depressed as needed, It is implemented using hydraulic pressure. When the road surface without ice sheets is moved, the visibility is diminished by controlling the hydraulic pressure, thus preventing road damage, energy saving, material cost reduction, work efficiency, and narrow road work.

In the case of a road with a lot of vehicles moving, a number of blades of a sector shape and a one-letter shape can be protruded and depressed according to need, and this is realized by the hydraulic pressure in which a cylindrical shape installed inside the roll is introduced. Minimize the adhered ice by applying non-hydrophilic material such as oil or paraffin to the blade surface so that the ice adhered to the roll is naturally detachable. When moving on a road without ice, the blade is recessed by controlling the hydraulic pressure, thus preventing damage to roads, saving energy, reducing material cost, improving work efficiency, and increasing work time.

Next, the device for collecting the ice fragments installed in the lower part of the vehicle has a triangular structure for collecting the pieces to the rear when the vehicle is moved by using the angle. The device for moving the gathered fragments to the loader is a conveyer belt, an inhaler, a screw, , And a transfer pump. The liquefaction and vaporization of ice debris that occurs in the loading box utilizes the engine heat of the vehicle or solar thermal energy. As a result, it is possible to prevent recurrence of ice roads, prevent port holes due to flooding of roads, mitigate vehicle traffic, and reduce workforce by removing broken ice from roads.

Next, by measuring the amount of debris collected in the device for collecting the debris, an appropriate amount of protrusion of the visibility and the blade is calculated to control the degree of protrusion of the visibility or the blade, thereby preventing damage to the road.

Next, as a general description of the vehicle, a special type of roll is used, and a hydraulic cylinder is provided at the hinge portion of the arm connected to the roll and the vehicle to control the load applied to the roll. Protrusion and depression are made possible. As a result, there is a road surface damage caused by unnecessary weight of the roll and material reduction, and there is an effect of work using an appropriate load according to the road surface situation.

2 is a perspective view showing the shape of the first roll of the present invention;
Fig. 3 is a perspective view showing the shape of roll 2 of the present invention
4 is a perspective view of the whole of the proposed vehicle.

    The first embodiment of the roll shape of the present invention will be described with reference to FIG. 2 for the purpose of de-icing a sidewalk through which people pass. As shown in FIG. 2, three layers and a viscous roll 11 are constituted for the supply of hydraulic pressure, and the thorns 13 are formed in a column shape having conical, triangular, Respectively. The rolls or crushing rolls can be controlled by hydraulic pressure during 'visibly protruding' and 'visibly recessed', and when visibly protruding, pressure is transmitted to the hydraulic pressure layer through the hydraulic line through an external hydraulic cylinder. As a result of the introduced pressure, the pressure is transmitted from the hydraulic layer to the visor, so that the visor protrudes out of the roll. At this time, the pressure applied to the thorns exceeds the resistance of the spring fixing pin, so that the movement of the thorns occurs.

At the time of 'visibility depression', the pressure of the hydraulic pressure layer is reduced, the visibility is located inside the edge of the roll, and is fixed at a given position through the spring fixing pin. The pressure of the hydraulic pressure layer is discharged to an external hydraulic cylinder through a hydraulic line (not shown). Reference numeral 16 denotes a form in which the roll is depressed. The spring fixing pin formed on the viscous body is fixed to the roll (outside), and the root portion of the thorn is recessed into the hydraulic layer. Reference numeral 15 denotes an outer shape of the roll when it is recessed inside the visible roll, and is used when moving the vehicle on a road surface without ice. As described above, the visible protrusion and the depression can be quickly changed by the adjustment of the hydraulic cylinder attached to the outside.

The roll corresponding to the second embodiment of the present invention will be described with reference to Fig. 3 as a shape for de-icing the road on which the vehicle travels. As in the case of the roll 21, there are three layers and blades in the region of the roll on which the blades are mounted, and the blades 23 are formed in a fan shape to prevent obstacle in the rotation of the rolls. The roll has two forms when the blade protrudes and when the blade protrudes. When the blade protrudes, the pressure is transmitted to the hydraulic layer through the hydraulic line through an external hydraulic cylinder. Pressure is transmitted from the hydraulic layer to the blade due to the inflow pressure to protrude into the roll 21. At this time, the pressure applied to the blade exceeds the resistance of the spring fixing pin, so that the movement of the blade occurs. 22, when the roll is rotated, the horizontal blade is horizontal and the vertical blade is designed so that the upper and lower edges are not connected to each other. This is because when the blade is depressed, 'To remove the phenomenon.

The pressure of the hydraulic pressure layer is reduced in the 'blade depression' so that the blade is positioned inward of the roll 21 and fixed at a given position through the spring fixing pin. The pressure of the hydraulic pressure layer is discharged to an external hydraulic cylinder through the hydraulic line. Reference numeral 26 denotes a state when the blade is depressed, and the spring fixing pin formed on the blade body is fixed to the roll 21, and the root portion of the blade is recessed into the hydraulic layer. Reference numeral 25 denotes an outer shape of the roll when the blade is depressed and is used when the vehicle is moving on a road without ice. Thus, the protrusion of the blade and the depression can be quickly changed by the adjustment of the hydraulic cylinder attached to the outside.

A flow meter 44 is provided at the rear end of the feed pump to measure the feed amount of the crushed ice water and connected to the hydraulic control device for controlling the hydraulic cylinder 30 controlling the degree of protrusion of the visibility or the blade by controlling the hydraulic pressure, If the flow rate of the flow meter is insufficient as compared with the flow rate of the flow meter 44, the flow rate of the flow of the flow meter is calculated by calculating the insertion depth of the visor 13 or the blade 23 in accordance with the visibility or the protrusion of the blade, Since the controller determines that the projection 13 or the blade 23 protrudes out of the roll excessively, the visibility or the protruding height of the blade is lowered. If the flow rate is a little higher, the ice sheet on the road may be thicker. A hydraulic control device (not shown) is operated to increase the height.

The overall structure of the whole vehicle is shown in Fig. 1 is a side view of the ice-making vehicle 1. Fig. A hinge for fixing the rod to the vehicle; a hydraulic cylinder and a hydraulic cylinder hydraulic pressure control device provided on the opposite side of the rod for applying pressure to the roll; An ice debris collecting device and an ice debris heating and moving unit located at the lower rear of the vehicle and a control vehicle. The pressure of the roll is adjusted by adjusting the height of the rod through the arm through the hydraulic cylinder, and the pressure transmitted to the roll is provided to the rod to control the hydraulic pressure by using the signal of the laser (50) Lt; / RTI > The laser scans a certain area and measures the state of the road surface passed by the roller. If there is no scan result on the road surface due to the movement of the roller, lower the hydraulic pressure of the roller, and if there is a lot of ice pieces on the road surface, the result of the scan will be reflected in the control when the road surface becomes uneven.

In addition, it is also possible to control the visibility or protrusion of the blade by using the amount of ice water measured by the flowmeter using the ice debris collecting device.
