DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in more detail with reference to the accompanying drawings.

1 to 2, the present invention relates to a joint cleaning apparatus for bridges, comprising: a fixing bracket 100 coupled to a lower front of a vehicle; A fixing plate 110 coupled with the fixing bracket; A lifting plate 120 coupled to the fixing plate so as to move up and down; A conveyance rail 130 coupled to the up / down steel plate and coupled along the width direction of the vehicle, the conveyance rail 130 having a predetermined length; A traveling roller 141 positioned at the front of the feeding rail, a traveling roller 142 coupled to each corner of the feeding plate and closely contacting the upper and lower edges of the feeding rail, A driving roller 144 connected to the first driving motor 143 and a cleaning member 140 configured by at least one cleaning nozzle 145 for removing foreign matters accumulated in the joint by spraying air or water to the bridge joint ).

The fixing bracket 100 is detachably coupled to a cleaner for cleaning the road or a bumper B provided in front of the water heater. A mounting bracket may be provided on the rear surface of the fixing bracket so that the mounting bracket can be mounted on the bumper, and the mounting bracket can be coupled through bolts.

A fixing plate 110 is coupled to the front of the fixing bracket 100. The fixing plate 110 supports the lifting plate 120, the feeding rail 130, and the cleaning member 140.

The elevated steel plate 120 is coupled to the fixed plate 110 so as to be able to move up and down. The construction and the method of ascending and descending the uplifting steel sheet will be described later.

The conveying rail 130 is coupled to the front of the elevating plate 120 along the width direction of the vehicle. The conveying rail 130 has a structure in which a circular pipe having a predetermined length is spaced up and down by a predetermined distance and a reinforcing plate is integrally formed therebetween. The conveyance rail 130 forms a movement path of the cleaning member 140 to be described later so that the cleaning member moves left and right along the conveyance rail to clean the joint J installed on the bridge. It is preferable that the length of the cleaning member is shorter than the width of the vehicle and the length of the cleaning member is shorter than the width of the vehicle.

The cleaning member 140 includes a conveyance plate 141 positioned in front of the conveyance rail and a traveling roller 142 coupled to each edge of the conveyance plate and closely contacting the upper and lower edges of the conveyance rail, A driving roller 144 connected to a first driving motor 143 provided at the upper center of the conveyance plate, and at least one cleaning nozzle 144 for ejecting air or water to the bridge joint to remove foreign substances accumulated in the joint, (145).

The cleaning member 140 causes the driving roller 144 to rotate through the power transmitted from the first driving motor 143 and the traveling roller 142 coupled to each corner of the feeding plate is driven by the driving roller 144 The conveying rail 130 is moved in the left and right directions.

In the present invention as described above, the cleaning member 140 moves in the left-right direction along the conveyance rail 130 and injects air through the cleaning nozzle 145 to discharge the removed foreign matter to the side of the roadside or the center separator side The foreign object thus removed can be smoothly removed by using a conventional sweeper for cleaning the road.

In the present invention, the use of a roller for moving the cleaning member 140 is intended to lower the manufacturing cost of the product, to facilitate maintenance and repair, and to improve work efficiency.

For example, when the cleaning member 140 is moved along the feed rail 130 via gears, a chain, or a wire, it can be simply moved left and right along the feed rail. However, There is a problem that the extension rail can not be folded.

That is, by moving the left and right movement of the cleaning member 140 through the rollers, even if there is a gap or step between the feed rail 130 and the extension rail 300, the roller can run sufficiently through the power , The manufacturing cost is lower than that of the gear and chain type or wire type, and maintenance and repair are easy.

Next, in the present invention, the cleaning nozzle 145 includes an air injection nozzle 146 for spraying air as shown in FIG. 2 to remove foreign substances accumulated in the joint, and a plurality of air injection nozzles 146 disposed in parallel on both sides of the air injection nozzle, And a pair of mist spray nozzles 147 for preventing the diffusion of the removed foreign matter by mixing the mist particles to prevent the diffusion of the foreign matter. The up and down steel strip 120 is provided with air or mist sprayed water particles Scattering prevention cover 500 is detachably coupled so as to prevent scattering of the removed foreign matter due to the influence of the wind and to prevent the foreign matter from diffusing to the road.

As described above, the bridge joint cleaning apparatus according to the present invention is provided in a sweeping or sprinkler. The sweeping or sprinkler is equipped with a water storage tank (not shown) for storing water and an air tank (not shown).

In the present invention, the cleaning nozzle 145 is connected to the water storage tank and the air tank so that mist spraying of water and air is performed.

In the present invention, the cleaning nozzle is divided into the air injection nozzle 146 and the mist injection nozzle 147. The foreign matter stacked on the joint J is sprayed with high pressure air to remove the removed foreign matter, So that the air and mist sprayed water particles are sprayed only inside the scatter preventive cover 500 to increase the cleaning efficiency.

The shatterproof cover is raised and lowered along the lifting plate. If the bottom surface of the shatterproof cover directly hits the road, the product may be shaken or damaged. Therefore, a protective plate (not shown) have.

Next, a pair of LM guide rails 200 are vertically coupled to the fixing plate 110, an LM block 210 is coupled to the LM guide rail 120 at a position corresponding to the LM guide rail, A second driving motor 220 is vertically installed between the LM guide rail and the LM guide rail of the fixing plate 110. A ball screw 230 and a nut 240 are connected to the second driving motor, .

When the ball screw 230 rotates through the rotational force of the second drive motor 220, the nut 240 coupled to the up / down steel plate moves up and down the up / down steel plate 120 along the ball screw 230 .

The reason why the lifting plate 120 is movable up and down in the present invention is that it prevents the product from being damaged by colliding with the overspeed preventing jaw formed on the road during driving and adjusts the height of the cleaning member 140, So that the sprayed air and mist can control the pressure or height at which the sprayed water particles are sprayed. In addition, a rubber plate is attached to the bottom of the shake-resistant cover 500 to prevent breakage of the shake-resistant cover, thereby ensuring the life of the product.

3, a pair of extension rails 300 hinged to each other through hinges 310 are provided at both ends of the conveying rail 130, And a support part 330, which is hinged to both the extension rail and the rod of the rail extension actuator, is attached to the end part of the extension rail, And an arc-shaped turning piece 340 are provided.

When the rod of the rail extension actuator 320 is pulled out, the extension rail 300 is folded via the support piece 330 and the rotation piece 340. When the rod returns, the extension rail 300 is returned to the original position, .

The reason why the extension rail 300 is foldably coupled in the present invention is that the extension rail 300 protrudes in a side lane so as not to interfere with vehicle flow during the cleaning operation of the joint J for bridges, So that the foreign matter conveyed to the center side of the road can be completely moved out of the road and the length of the conveyance rail can be extended according to the width of the road.

For example, if it is assumed that a joint is cleaned in two lanes of a road having a median separator at the center of the road and two lanes on both sides of the road, an extension rail The extension rail 300 provided on the left side is orthogonal to the feed rail 130 so as to prevent the vehicle passing through the one lane from colliding with the extension rail, And the foreign matter of the joint located in the two lanes can be completely removed by moving to the side of the road.

4A and 4B, the conveying rail 130 and the joint J are connected to each other so as to remove the foreign matter stacked on the joint in a state where the conveying rail 130 and the joint J are kept parallel to each other. And the angle is adjustable.

The reason for adjusting the angle of the feed rail 130 is that the air sprayed from the air and mist nozzles 146 and 147 and the mist sprayed water particles when the joint 130 and the joint J are not parallel The joint J is not accurately sprayed, so that the cleaning operation is not smoothly performed.

In order to solve such problems, the present invention may include a first fixing piece 400 formed on one surface of the elevating plate 120 and a second fixing piece 410 spaced apart from the first fixing piece by a predetermined distance; A first angle adjusting piece (420) hinged to the second fixing piece; A second angle adjusting piece (430) hinged to the other end of the first angle adjusting piece; A third fixing piece (440) formed on the conveying plate and hinged to the first fixing piece, and a fourth fixing piece (450) hinged to the second angle adjusting piece; And an angle adjusting actuator 460 having an end hinged to the first fixing piece and a rod hinged to the first and second angle adjusting pieces.

When the rod of the angle-regulating actuator 460 is pulled out or pulled out, the first and second angle adjusting pieces 420 and 430 rotate and push or pull the fourth fixing piece 450, The cleaning operation is performed in a state in which the feed rail 130 and the joint J are parallel to each other so that the angle of the rail can be changed.

In addition, a camera 600 for photographing the front side is installed on the upper inner circumferential surface of the shake-proof cover 500, and a monitor (not shown) is provided inside the vehicle for confirming the screen transmitted from the camera with the naked eye So that the operator can check the parallel state of the conveying rail and the joint through the monitor, and then perform the cleaning operation, thereby shortening the cleaning operation time and improving the working efficiency.

The present invention as described above includes a conveying rail 130 provided along a width direction of a road so as to remove foreign matters stacked on a joint for a bridge and a cleaning member 140 for spraying high pressure air while moving along the conveying rail, Can be detachably coupled to an existing road sweeper, thereby increasing work efficiency and reducing manpower and cost.
