In addition, a magnet plate 253 is attached to the inside of the blast head 250, which is a high speed sprayed steel ball is recoiled on the working surface and recovered through the recovery pipe 260, but a part of the blast head 250 is returned to the working surface. In this case, the steel ball remaining without being recovered is attached to the magnetic plate 253 by magnetic force and then recovered by the user. The magnetic force of the magnetic plate 253 is not enough to maintain the magnetic force enough to attach the steel sphere dispersed at high speed, it is sufficient if the magnetic force capable of raising the steel sphere remaining on the working floor surface to the magnetic plate 253 is maintained. . If the magnetic plate 253 is not mounted to the blast head 250, the magnetic plate 253 is not recovered to the recovery pipe 260 among the steel balls injected at a high speed under the supply pipe 240 by the impeller 230. The steel tool remains on the bottom of the working surface, and the remaining steel ball may remain on the bottom of the working surface intactly as the main body 100 moves forward as the work progresses.

The coupling member 400 for coupling and releasing the blasting machine 200 to the main body 100 includes first and second coupling plates 410 and 420 mounted on the front of the main body 100 and the blasting machine 200. The first coupling plate 410 is fixed to the front surface of the main body 100 in a flat plate shape and a second flat plate shape. A coupling plate 420 is hingedly connected to the first coupling plate 410. In addition, a hydraulic cylinder 450 is mounted between the first coupling plate 410 and the second coupling plate 420 to move up and down the second coupling plate 420. When the pressure is applied to the hydraulic cylinder 450, the second coupling plate 420 moves upward, and when the pneumatic pressure is removed from the hydraulic cylinder 450, the second coupling plate 420 is caused by its own weight. Allow to descend naturally to this side. In addition, the coupling shaft 425 of a predetermined length is integrally formed on the front surface of the second coupling plate 420 to support the blasting machine 200. The third coupling plate 430 connected to the coupling shaft 425 has a shaft groove formed in the upper side of the center, and is connected and fixed to the rear surface of the recovery pipe 260 by a pair of support plates. The coupling shaft 425 of the second coupling plate 420 is inserted into the shaft groove of the third coupling plate 430 and connected to each other, and the third coupling plate 430 is connected to the coupling shaft 425 in operation. A fixing groove penetrates up and down in front of the coupling shaft 425 and a fixing pin 426 is coupled to the fixing groove to prevent it from being separated. As described above, the second coupling plate 420 connected to the main body 100 and the third coupling plate 430 fixed to the blasting machine 200 are connected by one coupling shaft 425 and the shaft groove. The coupling plate 430 may rotate left and right about the coupling shaft 425. The pair of stoppers 421 may be formed on the front surface of the second coupling plate 420 to form the third coupling plate ( 430 may rotate only within the pair of stoppers 421.

As another work machine coupled to the main body 100, the planarizer, as shown in FIG. 4, has a box-shaped housing 320 having a lower opening connected to the third coupling plate 430 by a hinge, and the housing ( It consists of a flattening member 330 mounted in the 320, and a hydraulic motor 310 for driving the flattening member 330.

The hydraulic motor 310 is driven by receiving the hydraulic pressure of the hydraulic generator 120 by the hydraulic hose 140 and is mounted on the upper portion of the housing 320. In addition, the flattening member 330 driven by the hydraulic motor 310 and mounted in the housing 320 is a device for removing the latencies formed on the surface after the concrete is poured. 333 is formed, and the protrusion 333 removes the latency by rotation. Although the projection 333 removes the latencies while rotating by the horizontal axis 331, one end may be connected to the hydraulic motor 310 and the other end may use a vertical axis on which a grinding material is mounted. Such a flattening member 330 uses a grinding method currently used in this field.

Depth of removing the lattices is controlled by the wheels 341 and 342 mounted on the housing 320, and the wheels 341 are moved up and down by the adjuster 350 mounted on the front of the housing 320. It is possible to adjust the distance that the housing 320 is spaced apart from the work surface by the wheels 341 flowing in this way. That is, the length of the projection 333 of the planarizing member 330 exposed below the horizontal line extending the bottom surfaces of the front and rear wheels 341 and 342 may be adjusted by the controller 350, and thus exposed below the horizontal line. The depth to be flattened on the concrete floor is adjusted according to the length of the protrusion 333. The adjuster 350 has a handle formed on the upper surface and a male thread formed on the lower side thereof, so that the slide 342 having the female thread is lifted up and down, and a wheel 341 is mounted at the lower end of the slide 342.

The dust generated during the flattening operation is sucked into the dust collector 110 of the main body 100 through the hood 130 connected to the upper portion of the housing 320. The upper side of the housing 320 is connected to the third coupling plate 430 by a hinge, the third coupling plate 430 is connected to the coupling shaft 425 of the second coupling plate 420.

The operation and use of the planarizer and blasting apparatus combined device 10 according to the above configuration is as follows.

The planarizer and the blasting machine combined apparatus 10 according to the present invention, which are equipped with a traveling device, arrive at the bridge construction site requiring blasting work or planing work, and the blasting machine according to the necessary work among the working machines housed in the main body 100 ( 200 or the planarizer 300 is coupled to the front surface of the main body 100.

First, in order to perform a blasting (blasting) operation to remove rust and impurities on the surface of the bridge deck, the blasting machine 200 stored in the main body 100 is unloaded to form the third connecting plate 430 of the blasting machine 200. The coupling shaft 425 of the second coupling plate 420 is inserted into the shaft groove of the coupling shaft, and the fixing pin 426 is coupled to and fixed to the fixing groove of the coupling shaft 425 in order to prevent detachment during operation. When the hood 130 and the hydraulic hose 140 are connected to each other, work preparation is completed, and when the user removes the hydraulic pressure of the hydraulic cylinder 450, the first connection plate 410 and the second connection plate 420. ) Is connected to the hinge, and gradually descends to the working surface by the weight of the blasting machine 200, the blast head 250 and the wheel 251 is in contact with the bottom surface. When the work is prepared as described above, the user drives the hydraulic motor 220 by using the hydraulic pressure of the hydraulic generator 120 in the main body 100. The rotational force of the hydraulic motor 220 is transmitted to the impeller 230 by the belt 225, the impeller 230 is accommodated in the hoop 210 and lowered through the steel pipe dropping through the connection pipe 249 High speed jet towards The steel balls are sprayed at such a high speed to separate the rust or scale of the work surface in the lower portion of the blast head 250 by the impact and the steel balls bouncing upwards by the repulsive force to the hoop 210 through the recovery pipe 260. Move. At this time, the steel ball remaining on the bottom surface is not attached to the hoop 210 by the repulsive force is attached to the magnetic plate 253 mounted in the blast head 250. Therefore, even when the blasting operation proceeds to the front, the steel balls do not remain on the rear work surface, and the steel balls attached to the magnetic plate 253 can be easily collected by the user by hand. The dust and steel balls generated in the blast head 250 are collected by the hoop 210 along the curved recovery pipe 260, and the steel balls fall while colliding with the diaphragm 211 in the hoop 210. Is collected in the dust collector 110 in the main body 100 through the hood 130. Since the hood 130 sucks dust, a cover is attached to the upper surface of the hoop 210 so that it can be sealed, and the mesh 130 is prevented from passing through a steel ball through the hood 130 connected to the hoop 210. It is desirable to install it.

The iron ball recovered in the hoop 210 is sprayed downward by the impeller 230 through the connecting pipe 249 to remove the rust of the working surface again.

Lower surfaces of the wheels 251 and 252 provided at the lower side and the front and rear of the blast head 250 are formed to be maintained almost in a straight line so that the lower side of the blast head 250 is in close contact with the working surface. In addition, the lower surface of the blast head 250 is in close contact with the inclined bottom surface when the working surface is inclined back and forth or left and right. That is, when the working surface is inclined up and down, the hydraulic cylinder 450 mounted between the first coupling plate 410 and the second coupling plate 420 is in a state where the pressure is released, so that the blasting machine ( 200 moves freely up and down along the working surface. In addition, the second coupling plate 420 and the third coupling plate 430 are naturally connected to each other by one coupling shaft 425 in the case where the working surface is inclined left and right. However, the blasting 200 can be rotated only at a predetermined angle or less by a pair of stoppers 421 mounted in front of the second coupling plate 420. By such a configuration, the blast head 250 is in close contact with the bottom surface even when the working surface is inclined.

When the blasting operation is not performed and the blasting machine 200 is mounted, the third coupling plate 430 moves upward when a constant hydraulic pressure is generated in the hydraulic cylinder 450. The connected blasting machine 200 is also moved upward and spaced apart from the working surface by a certain distance. In order to release the blasting machine 200 from the main body 100 after the blasting operation, the second coupling plate 420 is first removed by removing the fixing pin 426 fixed to the fixing groove of the coupling shaft 425. The third coupling plate 430 and the hydraulic hose 140 and the hood 130 are separated from each other.

In order to planarize the working surface, such as when removing the lattices formed on the surface of the concrete, after the blasting machine 200 is released, the planer 300 is coupled to the main body 100. As in the coupling method of the blasting machine 200 described above, the coupling shaft 425 of the second coupling plate 420 is coupled to the through hole of the third coupling plate 430 of the planarizer 300, and the coupling is performed. The fixing pin 426 is inserted into the fixing groove of the shaft 425 to be fixed. And each of the hydraulic hose 140 and the hood 130 is also coupled. In addition, the height of the wheel 341 is adjusted by the adjuster 350 to adjust the depth to be smoothed. When the work is prepared as described above, the hydraulic motor 310 is driven, and the flattening member 330 interlocked with the hydraulic motor 310 rotates. As the projection 333 of the flattening member 330 rotates, the work surface is flattened, and the flattener 300 moves forward by the traveling of the main body 100 on which the traveling device is mounted. Dust generated during operation is sucked into the dust collector 110 in the main body 100 through the hood 130 connected to the upper side of the housing 320. The left and right flows and the up and down flows of the planarizer 300 are similar to those of the blasting machine 200 and thus will be omitted.

According to the configuration and action as described above of the present invention, the traveling device is mounted to move freely, can perform the flattening and blasting work as one equipment, can perform the work independently without the need of external power In addition, the dust and pollutants generated during the work is not scattered on the work site, especially when the work surface is inclined to the left and right or up and down, it is possible to work automatically.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
