Description

Chipping device of central reservation using water jet

The present invention relates to a chipping device, and more particularly, to a chipping device using a waterjet to scrape the outer surface to give the adhesive strength of the cement mortar to increase the height of the median of the highway.

In general, the central line of the highway, as shown in Figure 1 is provided with a central separator (1) of the weight of the cement having a center of gravity toward the bottom, the light shield plate for covering the headlights shining in the opposite lane on the upper surface of the central separator (1) (2) is installed.

However, as the height of the cement weight is lowered, the central separator installed with the light shield plate has a problem that a large vehicle easily collides with the ongoing vehicle on the other side and causes a second large accident when an accident occurs.

Therefore, in recent years, the government has devised a plan to increase the height of cement weights.

In order to increase the height of the central separator, the first step has been to remove all currently installed central separators and install the higher manufactured median separators.

This work method has been a problem of the disposal of the existing centrifuge was installed, and the problem of excessive dismantling, new production and reinstallation costs have emerged.

Therefore, as another method, a method of adding and expanding cement mortar by the height specified in the upper part of the existing central separator is proposed and performed.

However, in order to expand the existing median separator, the cement mortar layer is not simply stacked on the upper surface of the median separator, as shown in FIG. The central separator 5 should be integrated so that there is no structural problem.

Therefore, as shown in FIG. 3, the paint applied to the side of the existing median separator needs to be peeled off to cover the existing median separator, and the chipping to form a rough and uneven surface to increase adhesion to the cement mortar being overlaid ( chipping) (3).

For such a chipping operation, until now, the vibration device and the vibration device such as a vibrator have been performed manually.

As such, the chipping work performed by hand requires enormous manpower and has a problem of longer air.

For example, if you rely on manpower for chipping, you can only work about 10 meters per day. Currently there are many highways in our country, and if all these highways are chipped by hand, they will only need to be chipped for decades, without the need for huge manpower.

The present invention has been made to solve the above problems, to provide a chipping device that can perform a wide range of chipping operations in a short time by using a known waterjet sprayed at ultra-high pressure.

Is mounted. These wheels 115 may be equipped with a small motor (not shown) on each of them to automatically move the frame 110.

On the other hand, the central separator 1 has a lower width wider to have a center of gravity on the lower side, the first frame (110a) is bent to parallel to the outer bend of the wider lower portion of the central separator 1 as described above It would be desirable to have

In addition, the bottom of the first frame (110a) is formed with a drip tray 117 is opened at the top to collect the water or foreign matter generated during the work.

The waterjet unit 120 is modified to meet the purpose to be used in the present invention by using a well-known ultra-high pressure spraying device.

FIG. 5 is a detailed view of the waterjet unit shown in FIG. 4, and FIG. 6 is a bottom view of the nozzle bar as viewed from below to illustrate the formation position of the spray nozzle.

4 and 5, the waterjet unit 120 includes a pair of vertically parallel guides 121, an annular body 125 rotatably mounted inside the pair of guides 121, and a body 125. It consists of a support plate 128 is mounted across the inside of the) and the ultra-high pressure water injection device 140 is fixed to the support plate (128).

The pair of guides 121 are mounted on the outer surface of the guide 121 so that the guide roller 122 slides up and down on the outer surface of the guide 121 to vertically reciprocate along the first frame 110a. . At this time, the guide roller 122 is preferably provided in a plurality of pairs so that the guide 121 is not separated from the first frame (110a).

The annular body 125 has a hinge shaft 126 that is inserted into the guide 121 on both sides to freely rotate the body 125. At least two wheels 127 are mounted on the bottom surface of the body 125. At this time, the wheel 127 preferably has a structure that is formed so that the conventional showbar to elastically move in accordance with the rotation of the body 125. That is, when the waterjet unit 120 moves the curved surface while moving up and down along the first frame 110a, the body 125 is inclined. When the waterjet unit 120 is inclined, one wheel is heard and the opposite wheel is As it sinks, the showbar needs to be in place to cope with this phenomenon proactively.

Support plate 128 is fixed to both ends in the body 125, the gear box 130 is mounted on the upper surface of the support plate 128, the known high-pressure water injection device 140 on the upper surface of the gear box 130 And a drive motor 145 is coupled. At this time, the ultra-high pressure water injection device 140 is connected to a water supply line 141 connected from an external power pack (not shown) for supplying water at ultra high pressure, and the supply path 142 to which the supplied water is moved is geared It passes through the box 130 and the support plate 128 and extends below the support plate 128. At least two or more nozzle bars 143 branched into a propeller shape are coupled to the end of the supply path 142.

The nozzle bar 143 is a place where the ultra high pressure water is sprayed, and a plurality of spray nozzles 144 are formed on the lower surface of the nozzle bar 143. That is, a moving passage through which the ultra high pressure water is moved is formed in the nozzle bar 143, and a plurality of injection nozzles 144 communicating with the moving passage are formed. At this time, the injection nozzles 144 are formed to be spaced apart from each other, it is preferably formed so as not to be formed on the same arc as the injection nozzle 144 formed on the other nozzle bar 143. That is, as shown in FIG. 6, when the injection nozzles 144 formed on the nozzle bars 143 are formed on the same arc, the ultra-high pressure water is injected to the injection nozzles 144 while the nozzle bar 143 is rotated. Since the injection point of the ultra high pressure water is chipped to the same place, it is preferable to arrange them in the same arc shape to prevent this.

As such, the drive motor 145 for rotating the supply path 142 to rotate the nozzle bar 143 is coupled to the gearbox 130, and the drive motor 145 and the supply path 142 are gearbox 130. Is connected by a conventional power transmission means 147 such as a belt or a gear tooth. The driving motor 145 is connected to a power supply line 146 applied from the outside.

Next, a description will be given of the transfer means 150 for raising and lowering the waterjet unit 120.

The transfer means 150 is composed of a transfer motor 151, a cable 153 and the pulley 152. The transfer motor 151 is fixed on the upper surface of the frame 110, the pulley 152 is mounted on the lower surface of the frame 110. Therefore, the cable 153 circulated in the transfer motor 151 and the pulley 152 is wound and wound or unwound. The center of the cable 153 is fixed to the support plate 128 or the body 125 of the waterjet unit 120.

Alternatively, since the water jet unit 120 is heavy because the water jet unit 120 does not need a lower pulley, when the cable 153 is connected to the transport motor 151 and the water jet unit 120, the water jet unit 120 is connected to the water jet unit 120. When raising and lowering, the transfer motor 151 is wound up, and when the waterjet unit 120 is lowered, the transfer motor 151 is released and descends by the weight of the waterjet unit 120.

Hereinafter, the method and operation of the chipping device 100 formed as described above will be briefly described.

The frame 110 is mounted on the existing central separator 1 to perform the chipping operation. When mounted, the first frame 110a is spaced apart on the chipping surface of the center separator 1 such that the waterjet unit 120 mounted on the first frame 110a is in close contact with the chipping surface. That is, the wheel 127 of the waterjet unit 120 is in contact with the surface to be chipped, the nozzle bar 143 and the injection nozzle 144 is spaced at a predetermined interval. And the third frame (110c) is in close contact with the opposite side of the center separator 1 to suppress the frame 110 is separated from the center separator (1).

In this state, when the power and the ultra high pressure water are applied, the nozzle bar 143 is rotated by the driving motor 145, and the ultra high pressure water is injected into the injection nozzle 144 while rotating.

The sprayed ultra high pressure water peels off the paint applied on the chipping surface of the central separator 1, and cracks the outer layer of the cement mortar so as to chip.

At this time, since the nozzle bar 143 is rotated, the chipping surface of the rotating radius is chipped within a predetermined time, and when the predetermined time passes, the driving motor 151 is driven to raise or lower the waterjet unit 120. To allow chipping in other areas.

When all the widths corresponding to the rotation radius of the nozzle bar 143 are chipped in the longitudinal direction, the frame 110 is pushed to the front to chip the other areas. At this time, the wheel 115 formed in the frame 110 may be mounted so that the motor can be automatically moved without the user pushing by hand.

That is, the operation of the chipping device 100 may be operated while watching the same in the suction and purification device that follows in the subsequent process.

The suction and purification device is a device for chipping the central separator 1 by a water jet, and purifying water while picking up water and foreign substances by sucking water, paint and cement chips, which are by-products of this work.

That is, the suction device inserts a suction hose from the rear of the drip tray 117 formed at the lower end of the first frame 110a to vacuum suction, separates the vacuum sucked water and foreign substances from the purifier, and neutralizes the separated water again. Let's do it. Water generated during chipping contains strong alkalinity, which necessitates neutralizing it.

In addition, in order to smoothly suck the foreign matter and water loaded on the drip tray 117 with the suction suction hose, it is very effective to blow the air hose applied from the external compressor in front of the drip tray 117.
