Referring to FIG. 3, the container cone blasting device 100 includes a transfer unit 110, a blasting unit 120, a recovery unit 130, and a housing 135.

The housing 135 places the container cone 70 to be pretreated therein, and has an internal space in which the blasting unit 120 is located in the adjacent upper area of the container cone 70, so that the housing 135 is closed on all sides and has a top surface. The upper and lower surfaces are open and formed into a hollow, penetrating shape.

The side walls on all sides of the housing 135 may be closed with a plate made of an opaque material, but may be completely or partially made of a transparent material such as a transparent acrylic plate so that the blasting operation on the container cone 70 can be confirmed from the outside. may be formed.

A suction hose connector 140 may be formed on one side of the side wall of the housing 135. Through a suction hose (not shown) externally connected to the suction hose connector 140, the abrasives sprayed during the pretreatment process of the container cone 70, dust generated by the sprayed abrasives and compressed air are discharged to the outside. It can be. A vacuum pump (not shown) may be connected to the suction hose to provide suction to the outside of the housing 135.

Abrasives and dust discharged through the suction hose may accumulate in the receiving space formed by the recovery unit 130, and by forming an air flow in the inner space of the housing 135, the abrasives and dust accumulated in the receiving space are effectively removed. An external air inlet for introducing external air may be formed on one side of the side wall of the housing 135 so that the external air can be discharged (see FIG. 8).

A transfer unit 110 that transfers the blasting unit 120 may be provided on the open upper surface of the housing 135.

As shown in FIG. 4, the transfer unit 110 includes a first guide rail 310, a second guide rail 312, a first transfer element 315, a second transfer element 317, and a third guide rail. It may include 330 and a third transporter 335.

The first guide rail 310 and the second guide rail 312 extend along the first direction on opposite edges of the upper end of the housing, and are installed parallel to and spaced apart from each other.

A first transport body 315 is mounted on the first guide rail 310 so as to move along the direction of extension of the first guide rail 310 by a motor, which is a driving source (not shown), and on the second guide rail 312, a motor (not shown) is installed. The second transport member 317 is mounted to move along the extension direction of the second guide rail 312 by a motor, which is an unused driving source.

The first transport body 315 and the second transport body 317 each move at the same speed and direction along the corresponding first guide rail 310 or second guide rail 312, and stop at positions corresponding to each other. The operation may be controlled by a controller (not shown).

The third guide rail 330 extends in a second direction perpendicular to the extension direction of the first and second guide rails 310 and 312, and each end is connected to the first carrier 315 and the second carrier 317. ) is installed to be fixed to. Because of this, the third guide rail 330 is moved in the first direction together when the first and second transport members 315 and 317 are moved.

The third transport member 335 is mounted on the third guide rail 330 to move along the extension direction of the third guide rail 330 by a motor, which is a driving source (not shown).

A blasting unit 120 extending downward toward the inner space of the housing 135 is coupled to the third transporter 335 (see FIG. 3).

The blasting unit 120 may be formed with a fixed length extending toward the internal space of the housing 135 in consideration of the height of the housing 135, but may also be formed with a telescopic structure to allow expansion and contraction in length.

When the first and second carriers 317 are moved in the first direction and the third carrier 335 is moved in the second direction, the blasting unit 120 coupled to the third carrier 335 is To ensure stable support, the third guide rails 330 may be installed in parallel as a pair, as shown in FIG. 4 .

At this time, one third carrier 335 may be mounted on each of the pair of third guide rails 330 to form a pair, and the pair of third carriers 335 may have the same moving direction and speed. The movement can be controlled by the controller to move to and stop at the same location. Of course, it goes without saying that one third transport body 335 may be mounted to move along the pair of third guide rails 330.

As described above, the transfer unit 110 moves the blasting unit 120 in the first direction and/or the second direction so that the spray nozzle 420 of the blasting unit 120 is aligned with the container cone 70 on the bottom of the cargo hold. It can be located in the adjacent upper area of .

The blasting unit 120 coupled to the third transport body 335 of the transport unit 110 and arranged to extend downward toward the internal space of the housing 135, as shown in FIG. 5, is connected to the injector body 400. ), may include an abrasive supply unit 410 and a spray nozzle 420.

A blasting hose may be introduced through the open upper surface of the housing 135 and fastened to the abrasive material supply unit 410 to supply abrasive material. The abrasive supplied through the abrasive supply unit 410 flows into the sprayer body 400 together with compressed air supplied from a compressed air supply unit (not shown) and is sprayed toward the container cone 70 through the spray nozzle 420. .

At this time, the spray nozzle 420 is pre-treated so that the upper surface of the double pad 60 to which the container cone 70 is welded and the surface of the container cone 70 can be pretreated as a whole (see (b) of FIG. 2). It has a designated inclination angle and is mounted on the sprayer body 400 as a rotary nozzle structure that rotates around the vertical axis (P in Figure 5) passing through the center point of the joint where the sprayer body 400 and the spray nozzle 420 are combined. do. To this end, the sprayer body 400 may be equipped with a rotation drive unit (not shown) to rotate the spray nozzle 420.

In this way, the injection nozzle 420 mounted at a predetermined inclination angle is driven to rotate with the near end (i.e., the end on the sprayer body side) as the center of rotation, so that the far end of the injection nozzle 420 (i.e., the container cone (i.e., container cone) The end (relatively adjacent to 70) moves over a relatively wide area and sprays the abrasive, which causes the double pad 60 to apply abrasive to a wide area including not only the upper surface but also the side of the container cone 70. can be sprayed.

In order to enable the injection nozzle 420 to pre-process the entire area of the container cone 70, the controller controls the transfer unit 110 to target the container cone 70, as shown in FIG. 6. It is possible to manipulate and control the position of the relative blasting unit 120 to change.

As shown in FIG. 6, in order to pre-treat the entire top and side surfaces of the container cone 70 and the upper surface of the double pad 60 adjacent to the container cone 70, a sprayer coupled with a spray nozzle 420 is used. The body 400 must be able to move in the plane of the first and second directions in response to the position of the container cone 70, and the spray nozzle 420 for spraying the abrasive is also mounted to achieve a predetermined inclination angle. It must be rotated.

To this end, the transfer unit 110 to which the blasting unit 120 is fastened is operated to move horizontally in the first and second direction planes, and the spray nozzle 420 of the blasting unit 120 uses only one drive shaft. It features a rotating nozzle structure to ensure an effective work range.

Since the spray nozzle 420 is mounted to have a pre-specified inclination angle, random pre-processing work for a designated area range is possible, and this has the feature of eliminating the control burden for accurately aiming the work position.

In addition, in order to prevent environmental pollution during pretreatment using abrasives, the entire area around the blasting device is sealed to suppress the dispersion of abrasives sprayed at high speed, thereby improving the probability of securing good work quality for the work range, once the device is installed. It also has the feature of solving the existing problem of not being able to check exactly where and how work was done in real time until the work was completed.

Referring again to FIG. 3, the recovery unit 130 is disposed in the lower part of the internal space of the housing 135 so as to contact the floor (eg, cargo hold floor).

As shown in Figure 7, the recovery unit 130 includes a first group forming box 710, a second group forming box 715, first and second blocking boxes 720, 725, and first and second group forming boxes. It may include inclined plates 730 and 735.

The first group forming box 710, the first blocking box 720, the second group forming box 715, and the second blocking box 725 are sequentially connected in a ㅁ shape by the first group forming box 710, etc. Forms an enclosed collection space. A double pad 80 to which the container cone 70 is welded is located in the collection space formed through the vertical direction, and the container cone 70 and the double pad ( 80), the abrasive is sprayed on the target.

As shown in Figure 8, the first and second group forming boxes 710, 715, which cause air flow in the collection space, are arranged to face each other, and the first and second group forming boxes 710, 715 are It has a hollow internal space that allows air to flow through the body.

The first air forming box 710 has a through slot of a predetermined length formed on the upper side of the external air inlet side so that the air flowing in from the external air inlet flows into the internal space of the first air inlet forming box 710, and a through slot of a predetermined length is formed in the internal space. A through slot of a predetermined length is formed in the lower part of the side of the collection space so that the flow direction of the inflow air is changed and discharged into the collection space.

In response to this, the second group forming box 715 is formed with a through slot of a predetermined length at the lower part of the side of the collection space side so that the air flowing into the collection space flows into the inner space of the second group forming box 715. , an outlet 717 is formed on the side of the suction hose connector so that the direction of air flowing into the internal space is changed and discharged to the outside. Here, the outlet 717 and the suction hose connector 140 may be connected to each other using a connecting hose (see FIG. 9).

That is, the first and second group forming boxes 710 and 715 have a through slot formed on the side of the collection space disposed at the bottom, so that an air flow is generated downward within the collection space, so that the abrasives located in the collection space and Dust can be discharged effectively.

In addition, the first and second group forming boxes 710 and 715 are arranged so that the through slot or outlet 717 formed on the side far from the collection space is not parallel to the through slot formed on the side of the collection space, thereby preventing abrasives and dust from flowing. The diffusion space may be limited to the collection space formed by the recovery unit 130.

In order to effectively collect abrasives and dust in the collection space, the collection space formed by the first and second group forming boxes (710, 715) and the first and second blocking boxes (720, 725) is expanded upward. As the cross-sectional area of the collection space progresses downward, each of the first and second inclined plates 730 and 735 has a downward narrow slope that corresponds to the first group forming box 710 or the second group forming box 715 and It may be fixed to the side wall of the corresponding housing 135.

Of course, the inclined plate is formed into a shape in which the cross-sectional area of the collection space decreases as it moves downward in all four directions, as well as the first and second group forming boxes 710 and 715, as well as the first and second blocking boxes 720 and 725. It is natural that it can be installed with a narrow downward slope.

Figure 9 shows the shape of the container cone blasting device 100 with the area limiting cover 910 installed.

Generally, during pretreatment using abrasives, a shelter is formed that completely closes the surrounding area at the small block stage, and inside the shelter, abrasives are mixed with compressed air and sprayed at high speed to prevent environmental pollution due to the spread of abrasives and dust. I'm doing it.

In addition, even in the case of mobile work using a blasting device, the recovery of abrasives and dust is very important, so sealing the blasting device itself or the abrasive spraying area is very important.

In order to seal the abrasive spraying area, as shown in FIG. 9, an area-defining cover 910 is installed to separate the inner space of the housing 135 of the container cone blasting device 100 into an open upper area and a closed lower area. ) can be installed.

The area-limiting cover 910 is fixed to the four side walls of the housing 135 so that the four edge areas are formed to close all four directions, and one area of the body area is fixed to the outer peripheral surface of the injector body 400. Can be installed in interior space.

At this time, the lower part is closed in the internal space of the housing 135 by the four side walls of the housing 135 formed to close on all sides, the lower surface of the area limiting cover 910, and the bottom of the cargo hold to which the container cone 70 is welded. A region is formed. In this case, the container cone 70 to be pretreated, the double pad 60 to which the container cone 70 is welded, and the spray nozzle 420 are located in the closed lower area.

Compressed air and abrasives sprayed with strong injection pressure from the injection nozzle 420 expand the closed lower area of the internal space of the housing 135, and the closed lower area can be maintained even when the closed lower area is expanded. For example, the area-limiting cover 910 may be made of a flexible fiber material. Of course, it goes without saying that the area-limited cover 910 can be made of a fiber material that has a strength that does not cause damage by dispersed abrasives.

In addition, the area-limited cover 910, one side of which is fixed by the sprayer body 400, is made of a flexible fiber material, so that the blasting unit ( 120) It is natural to be able to respond flexibly even if the location changes.

Abrasives and dust present in the upper surface of the double pad 60 and the lower area closed for pretreatment of the container cone 70 may be discharged through a suction hose externally connected to the suction hose connector 140. At this time, it is natural that the suction hose connector can be formed on the side wall of the housing 135 at a position corresponding to the closed lower area to discharge the abrasives and dust to the outside through the suction hose.

When a suction hose is externally connected to the suction hose connector 140 and suction pressure by a vacuum pump is applied to the suction hose, abrasives and dust collected in the collection space formed by the recovery unit 130 are discharged to the outside.

That is, the suction pressure applied to the suction hose causes a negative pressure to be applied to the lower space closed by the area limiting cover 910 in the inner space of the housing 135, and the outside air is closed from the outside air inlet formed on the side wall of the housing 135. It is allowed to flow into the lower area, and the introduced outside air is discharged through the receiving space and through the suction hose connector 140. In this process, a strong air flow is generated in the receiving space within the closed lower area, which accelerates the external discharge of abrasives and dust collected in the receiving space.

Here, in order to generate a strong air flow in the receiving space due to air discharge through the suction hose connector 140 and outdoor air inflow through the outdoor air inlet, the suction hose connector 140 and the outdoor air inlet are connected to the recovery unit 130. It is natural that they can be formed on the side walls of the housing 130 separated from each other by .

As described above, the cone blasting device according to this embodiment is welded and installed on the upper surface of the double pad at the bottom of the cargo hold and can be effectively used for pretreatment work on cones that have a protruding three-dimensional shape and are arranged at regular intervals, and can be used in an enclosed space. It has the advantage of effectively responding to environmental regulations by suppressing the spread of abrasives and dust generated during blasting work.

Although the present invention has been described above with reference to embodiments, those skilled in the art can modify the present invention in various ways without departing from the spirit and scope of the present invention as set forth in the claims below. and that it can be changed.
