Description

Transport device and transport method {Apparatus for transporting object and method for transporting object}

The present invention relates to a transport device and a transport method, and more particularly, to a transport device and a transport method capable of easily removing foreign substances.

In general, a steel mill produces wire rods, coils, thick plates, and the like, which are final products through a wire-making process, a steel-making process, a casting process, and a rolling process. Among them, in the steelmaking process, in order to remove impurities such as carbon (C), phosphorus (P), and sulfur (S) in the molten iron (molten iron) produced in the blast furnace, molten iron is put into a converter and pure oxygen is blown into the molten steel in a clean state. to produce This molten steel is put in a ladle, and the ladle is loaded onto a bogie and transported for subsequent processing.

In this case, in a steelmaking plant or a preliminary processing plant where the steelmaking process is performed, the ladle may be transferred to a bogie on the ground by using a overhead crane, or the ladle located on the bogie may be transferred to another place. The bogie can transport the ladle while moving along the rail with the ladle loaded on the upper part.

However, as the bogie moves with the ladle, foreign substances such as dust and dirt may accumulate on the bogie. In particular, a lot of foreign substances may be accumulated around the part where the ladle is seated on the bogie. Therefore, the hook of the overhead crane collides with foreign substances, and the overhead crane may not be able to seat the ladle on the bogie or transfer the ladle to the outside of the bogie.

In addition, an accident in which a moving hook is caught by a foreign substance and derails may occur, and an accident in which a hook caught in a foreign substance moves suddenly and collides with the ladle may occur. Accordingly, the hook or ladle may be damaged, and the life of the hook or ladle may be reduced.

The body member 1110 may be formed in a rectangular frame shape. For example, the body member 1110 may include a pair of first connecting bars 1111 extending in the transport direction, and a pair of second connecting bars 1112 extending in the cross direction. That is, one of the second connection bars 1112 may be coupled between the front ends of the first connection bars 1111 , and the other may be coupled with the lower ends of the first connection bars 1111 . The first connecting bar 1111 and the second connecting bar 1112 may be formed in a square shape beam shape.

Here, a rectangular hole 1113 may be formed in the center of the body member 1110 . Here, the center may be the center of the length of the body member 1110 in the transport direction and the cross direction. The area of the hole 1113 may be formed to be larger than the cross-sectional area of the container member 11 . Accordingly, when the protruding member 12 is seated on the seating member 1150 , the container member 11 of the object 10 is inserted into the rectangular hole 1113 , and the lower portion of the object 10 is inside the hole 1113 . can be located in

In addition, the body member 1110 includes a first space 1120 formed at a position lower than a position where the removal unit 1200 pushes the foreign material P, and a second space 1130 separated from the first space 1120 . ) can have The crushing unit 1300 may be disposed in the first space 1120 , and the removing unit 1200 may be disposed in the second space 1130 . For example, the first space 1120 may be formed at the front end of the first connecting bar 1111 . Here, an upper portion of the first space 1120 may be opened. Accordingly, the foreign material P may be introduced into the first space 1120 through the open upper part.

Also, the second space 1130 may include a first area 1131 and a second area 1132 . The first region 1131 may be a space located outside the first space 1120 with respect to the crossing direction and formed along the transport direction. Here, the direction in which the rectangular hole 1113 is positioned with respect to the crossing direction with respect to the first connecting bar 1111 may be the inside, and the opposite direction may be the outside. Also, a length in the transport direction of the first region 1131 may be longer than a length in the transport direction of the first space 1120 . Also, an upper portion of the first region 1131 may be opened.

The second region 1132 may be a space formed inside the first region 1131 while being behind the first space 1120 . That is, in the second region 1132 , the length in the cross direction is formed to have a length similar to the length in the cross direction of the first space 1120 , and the length in the transfer direction is equal to the length in the transfer direction of the first region 1131 and the first space ( 1120) may be a space formed with a length similar to the difference in length in the transport direction. In addition, the upper portion of the second region 1132 may be covered by the wall of the body member 1110 to be blocked. Hereinafter, a wall covering (ie, covering) the upper portion of the second region of the body member 1110 is referred to as an upper wall 1114 . Here, the foreign material P may be mainly accumulated on the upper wall 1114 of the body member 1110 . A detailed description thereof will be given again below.

In addition, an outlet 1115 may be provided at the front end surface of the first connecting bar 1111 . The outlet 1115 may communicate with the first space 1120 , and may communicate with the recovery member 1340 of the crushing unit 1300 to be described later.

The wheel 1140 may movably support the body member 1110 . For example, the wheel 1140 may be a wheel. The wheel 1140 is provided in plurality and is installed on both sides of the lower portion of the body member 1110, respectively. It may be disposed on the rail 30 . For example, the wheel 1140 may be disposed in the first area 1131 of the second space 1130 , and may be connected to the power transmission member 1320 of the crushing unit 1300 to be described later.

Meanwhile, the body member 1110 may be detachably connected to a train (not shown). That is, the body member 1110 may move by the movement of the train. Accordingly, the train pulls the body member 1110 , the wheel 1140 may rotate on the rail 30 , and the body member 1110 may advance along the rail 30 .

The seating member 1150 is positioned above the body member 1110 , specifically, above the second region 1132 of the second space 1130 , and can support the object 10 . The seating member 1150 is provided as a pair, and may be installed on the upper surface of the body member 1110 , that is, the upper wall 1114 . For example, the pair of seating members 1150 may be disposed at a position adjacent to the hole 1113 on the upper surface of the body member 1110 . In addition, the seating member 1150 may be formed to extend in the vertical direction to have a higher height than the removal plate 1232 of the removal part 1200 to be described later. Accordingly, the seating member 1150 may be in contact with the protruding member 12 to support the object 10 . In addition, the insertion hole 1151 penetrates in the vertical direction and communicates with the second space 1130 so that the transfer member 1220 of the removal unit 1200, which will be described later, can be installed inside the seating member 1150 . can be formed.

Meanwhile, in the process in which the object 10 is seated, the metal fixed to the outer circumferential surface of the object 10 may fall to the upper wall 1114 adjacent to the seating member 1150 . Alternatively, the molten material inside the object 10 may be scattered and splashed onto the upper surface of the body member 1110 . At this time, the molten material may mainly splash toward the upper wall 1114 adjacent to the seating member 1150 . The scattered melt may fall and be fixed to the upper wall adjacent to the seating member 1150 . Accordingly, on the upper wall 1114 adjacent to the seating member 1150 , that is, the foreign material P may be accumulated. In this case, the foreign material P accumulated on the upper surface of the body member 1110 may be removed through the removal unit 1200 .

2, 3 and 5 , the removal unit 1200 pushes the foreign material P accumulated on the body unit 1100 to remove the foreign material P from the upper surface of the body unit 1100 . . The removal unit 1200 may be disposed in the second space 1130 , and at least a part of it may be installed in the body unit 1100 to be movable. The removal unit 1200 may include a base 1210 , a transmission member 1220 , and a removal member 1230 .

The base 1210 may be disposed under the second space 1130 . The base 1210 may be a plate extending in the transport direction and the cross direction. In addition, the base 1210 may include a first support bar 1211 that extends in the vertical direction, the transmission member 1220 is coupled to the upper end. For example, the first support bar 1211 may be disposed below the seating member 1150 in the cross direction, and may be disposed in front of a position where the insertion hole 1151 is formed in the transport direction. In addition, the first support bar 1211 may have a groove recessed in the upper and lower directions and a hole penetrating in an intersecting direction so that the transmission member 1220 can be coupled thereto.

At least a portion of the transmission member 1220 may protrude upward of the seating member 1150 and may be movably disposed in the second space 1130 . Accordingly, the transmission member 1220 may be in contact with the object 10 to provide the load of the object 10 as a driving force to the removal member 1230 . Also, the transmission member 1220 may include a first body 1221 , a second body 1222 , and a guide bar 1223 .

The first body 1221 may extend in the vertical direction and may be inserted into the insertion hole 1151 of the seating member 1150 . That is, the first body 1221 may be disposed in the insertion hole 1151 and the second region 1132 of the second space 1130 so that a part of the first body 1221 protrudes above the seating member 1150 . Accordingly, the first body 1221 may move downward in contact with the object 10 . The first body 1221 may have a hole to be penetrated in the cross direction with the vertically recessed groove at the lower end so that the second body 1222 is rotatably coupled. For example, the first body 1221 may be hinged with the second body 1222 .

The second body 1222 may have a bar shape extending in a cross direction. The second body 1222 has a rear end rotatably coupled to the first body 1221, a front end coupled to the guide bar 1223, and a portion between the front end and the rear end is a base ( It may be rotatably coupled to the first support bar 1211 of the 1210 . For example, the second body 1222 may be hinged to the first support bar 1211 to rotate clockwise or counterclockwise. Accordingly, the front end and the rear end of the second body 1222 may move upward and downward, respectively, or may move downward and upward.

The guide bar 1223 is provided in a cylindrical shape extending in the cross direction, and may be inserted into the removal member 1230 . More specifically, the guide bar 1223 is inserted into the slit 1231a of the removal member 1230 to be described later, and can move along the formation direction of the slit 1231a. That is, in association with the rotation of the second body 1222, it can move upward or downward while being inserted into the slit 1231a.

Meanwhile, a structure in which the first body 1221 , the second body 1222 , and the guide bar 1223 of the transmission member 1220 are combined is referred to as a seesaw structure. Here, the seesaw structure is a structure that provides a force to an object using the principle of a lever, a fixed fulcrum (ie, the first support bar) supporting the rod (ie, the second body), and a force point that applies a force (ie, the second body) 1 body). It may consist of an action point (guide bar) where a force is applied. The seesaw structure allows the applied force to be greater than the applied force. The operation and effect through the seesaw structure will be described together while explaining the operation of the removal member 1230 to remove the foreign material P, which will be described later.

The removal member 1230 may be disposed on the upper surface of the body portion 1100 so that at least a part thereof is movable so as to be in contact with the foreign material P. Accordingly, the removal member 1230 may move and push the foreign material P. That is, while the removal member 1230 is in contact with the foreign material P, it moves in the transport direction together with the foreign material P, and the foreign material P can be removed from the upper surface of the body member 1110 . In addition, the removal member 1230 may include a movable plate 1231 and a removal plate 1232 .

The moving plate 1231 may be disposed in the first area 1131 of the second space 1130 and may have a bar shape that is inclined downward with respect to the transport direction. The moving plate 1231 may move along the transfer direction within the first area 1131 . In addition, the movable plate 1231 may include a slit 1231a penetrating in a cross direction and inclined downward, and an elastic body 1231b disposed in the slit 1231a and capable of stretching and contracting. Here, the guide bar 1223 is inserted into the slit 1231a in a cross direction, the guide bar 1223 is pressed by the elastic body 1231b, and may be disposed at the front end of the slit 1231a.

The removal plate 1232 may come into contact with the foreign material P, and may push the foreign material P in the transfer direction. The removal plate 1232 is coupled to the rear end of the movable plate 1231 , and may be disposed on the upper surface of the body member 1110 . The removal plate 1232 may have an area capable of covering the foreign material P. For example, the removal plate 1232 may be formed in the form of a plate having a predetermined width in the transport direction and a predetermined area in the cross direction and the vertical direction. Here, the inner surface of the removal plate 1232 may be provided to be adjacent to or in contact with the outer surface of the seating member 1150 . Accordingly, it is possible to prevent a gap from being formed between the removal plate 1232 and the seating member 1150 , so that foreign substances do not leak into the gap between the removal plate 1232 when moving.

On the other hand, when the guide bar 1223 inserted into the moving plate 1231 moves upward by the seesaw motion, a force can be applied to the moving plate 1231 upward, and along the inclined direction of the penetrating slit 1231a. The guide bar 1223 moves upward while being inserted into the slit 1231a, and the movable plate 1231 may come forward. At this time, the removal plate 1232 coupled to the moving plate 1231 also moves forward together, and the foreign material P can be moved forward by pushing it. That is, the movable plate 1231 coupled to the removal plate 1232 may be advanced along the first region 1131 of the second space 1130 having an open upper portion. Here, the front end of the movable plate 1231 may move to the front end of the first region 1131 , and the removal plate 1232 may move to the front end of the second region 1132 .

Accordingly, the removal plate 1232 may drop the foreign material P into the first space 1120 in which the crushing unit 1300 is disposed. Here, since a relatively greater force than the force provided from the object 10 is provided to the removal member 1230 through the seesaw structure, it is possible to effectively push the foreign material P with a relatively small force.

2 to 5 , the crushing unit 1300 serves to crush the foreign material P pushed by the removal unit 1200 . The crushing unit 1300 is connected to any one of the wheels 1140 of the wheels 1140 provided in the body 1100 , and at least a part thereof may rotate in association with the rotation of the wheel 1140 . Hereinafter, a case in which the crushing unit 1300 is connected to the wheel 1140 provided at the front end of the body 1100 will be exemplarily described. That is, the crushing unit 1300 may be disposed in the first space 1120 , and may be connected to the wheel 1140 disposed under the second space 1130 .

In addition, the crushing unit 1300 may include a crushing member 1310 that comes in contact with foreign substances to crush it, and a power transmission member 1320 that rotates by rotation of the wheel 1140 and transmits the rotational force of the wheel 1140. there is. In addition to this, the crushing unit 1300 includes a guide member 1330 that can guide the foreign material P to move toward the crushing member 1310 and a recovery member 1340 that can collect the crushed foreign material P. may include more.

The crushing member 1310 may rotate in association with the rotation of the wheel 1140 , and may crush the foreign material P into relatively small particles by applying an impact to the foreign material P during rotation. The crushing member 1310 may be disposed at the center of the length in the transport direction and the center of the length in the cross direction of the first space 1120 . Also, the crushing member 1310 may include a rotating body 1311 and a crushing protrusion 1312 . In addition to this, the crushing member 1310 may further include a scraper 1313 installed on the crushing protrusion 1312 .

The rotating body 1311 is connected to the power transmission member 1320 and may rotate using the rotational force of the wheel 1140 transmitted through the power transmission member 1320 . For example, the rotating body 1311 may have a cylindrical shape extending in the vertical direction. Accordingly, the rotating body 1311 has a rotating shaft serving as a center of rotation in the vertical direction, and may rotate in a clockwise or counterclockwise direction based on the vertical direction.

The crushing protrusion 1312 may be coupled to the outer circumferential surface of the rotating body 1311 and may be formed to extend helically along the vertical direction. Here, the crushing protrusion 1312 may have a helical shape in which the diameter gradually increases from the upper side to the lower side. Accordingly, the foreign material P pushed by the removal unit 1200 and falling into the first space 1120 may be in contact with the spiral-shaped crushing protrusion 1312 and may be sequentially crushed from the contacted portion.

The scraper 1313 is installed at the end of the crushing protrusion 1312, and may have a shape in which a plurality of teeth protrude. Here, the tip of the scraper 1313 may be sharply formed. Accordingly, the scraper 1313 rotates together with the crushing protrusion 1312, and the foreign material P can be crushed more effectively.

The power transmission member 1320 is respectively connected to the wheel 1140 and the crushing member 1310 , and may provide the rotational force of the wheel 1140 to the crushing member 1310 . Here, the power transmission member 1320 may connect the rotation shaft of the wheel 1140 disposed in the cross direction and the rotation shaft of the crushing member 1310 disposed in the vertical direction. That is, the power transmission member 1320 may transfer the driving force by connecting the rotation shafts that are intersected with each other. In addition, the power transmission member 1320 may include a shaft 1321 , a first gear 1322 , and a second gear 1323 .

The shaft 1321 may have a cylindrical shape extending in the cross direction. The shaft 1321 may be coupled to the wheel 1140 such that the rotating shaft is disposed on the same axis as the rotating shaft of the wheel 1140 . Accordingly, when the wheel 1140 rotates, the shaft 1321 may also rotate.

The first gear 1322 may be installed at an end of the shaft 1321 , and a rotating shaft may be disposed coaxially with the rotating shaft of the shaft 1321 . Accordingly, the first gear 1322 may rotate together with the shaft 1321 .

The second gear 1323 may mesh with the first gear 1322 . That is, the first gear 1322 and the second gear 1323 may be a conical gear that transmits a kinetic force between two rotating shafts crossing each other. For example, the first gear 1322 and the second gear 1323 may include bevel gears. Accordingly, the shaft 1321 receives the rotational force having the crossing direction as the rotational axis from the wheel 1140 and converts it into the rotational force with the vertical direction as the rotational axis through the first gear 1322 and the second gear 1323, and the crushing member ( 1310) may transmit a driving force.

The guide member 1330 may be installed on the body 1100 and inclined downward toward the crushing member 1310 . That is, the guide member 1330 may be installed in the body portion 1100 forming the first space 1120 , and may be disposed inclinedly toward the crushing member 1310 from the upper portion of the first space 1120 . For example, the guide member 1330 may be formed in a plate shape having a predetermined area. Accordingly, the foreign material P pushed by the removal unit 1200 may flow along the guide member 1330 and fall to the upper side of the crushing member 1310 . Accordingly, it is possible to prevent the foreign material P from falling into the first space 1120 without contacting the crushing member 1310 .

The recovery member 1340 may recover relatively small particles of foreign matter P that are crushed from the crushing member 1310 . The recovery member 1340 may include a recovery member body 1341 and a magnetic body 1342 .

The recovery member body 1341 may have a space therein and may have a rectangular parallelepiped box shape with an open top. The recovery member body 1341 may be coupled to a front end of the body 1100 , for example, a portion in which the outlet 1115 is formed. In addition, the recovery member body 1341 may be provided with an inlet at the lower end of the rear side. The inlet may communicate with the outlet 1115 .

In addition, guide plates 1341a may be formed at the upper and lower portions of the inlet, respectively. The guide plate 1341a may have a plate shape that is inclined downward. The guide plate 1341a serves to guide the crushed foreign material P to smoothly flow into the inside of the recovery member body 1341 . Accordingly, the foreign material P of relatively small particles crushed in the first space 1120 may be introduced into the internal space of the recovery member body 1341 through the inlet and the guide plate 1341a and stored therein.

The magnetic body 1342 may come into contact with the crushed foreign material P, and may classify a metal material among the crushed foreign material P. That is, it is possible to extract a metal material from the crushed foreign material P. The magnetic body 1342 may be provided in plurality, and may be disposed side by side on the bottom surface of the recovery member body 1341 . For example, the magnetic material may be provided as a magnet. Accordingly, when the crushed foreign material P is introduced into the recovery member body 1341 , the magnetic body 1342 may pull the metal material by using magnetic force.

The structure and shape of the components of the transport device 1000 described above are not limited thereto, and may vary.

On the other hand, the process in which the removal unit removes foreign substances and the crusher crushes the foreign substances in the transport device according to the first embodiment of the present invention will be described together while explaining the transport method according to the first embodiment of the present invention.

6 is a perspective view of a transport device according to a second embodiment of the present invention, and FIG. 7 is a view showing the operation of the removal unit according to the second embodiment of the present invention. A structure of a transport device according to a second embodiment of the present invention will be described with reference to FIGS. 6 and 7 . In this case, a description of the same structure as that of the first embodiment of the present invention will be omitted.

The base 1210 of the body 1100 may further include a second support bar 1212 positioned in front of the first support bar 1211 . For example, the second support bar 1212 may be disposed at the front end of the base 1210 . The second support bar 1212 may have a longer vertical length than the first support bar 1211 . The second support bar 1212 may have a vertically recessed groove and a hole penetrating in the cross direction at the upper end so that the auxiliary transmission member 1240 to be described later can be movably coupled thereto.

The removal unit 1200 may further include an auxiliary transmission member 1240 capable of transmitting the driving force of the transmission member 1220 to the removal member 1230 .

The front end of the auxiliary transmission member 1240 may be rotatably coupled to the second support bar 1212 . For example, the auxiliary transmission member 1240 may be hinged to the second support bar 1212 . The lower end of the rear side of the auxiliary transmission member 1240 is bent downward, and may be connected to the transmission member 1220 . Accordingly, the auxiliary transmission member 1240 may move upward or downward in response to the rotation of the second body 1222 of the transmission member 1220 . In addition, the auxiliary transmission member 1240 may be provided with an auxiliary guide bar 1241 at the upper end of the rear side. The auxiliary guide bar 1241 extends in the cross direction and may be inserted into the slit 1231a of the movable plate 1231 . Accordingly, the auxiliary guide bar 1241 may be connected to the movable plate 1231 at a position relatively higher than the front end of the transmission member 1220, and the inclined angle of the movable plate 1231 therefrom is relatively gentle. can be formed.

In general, a force has a direction, and the magnitude of the force at a point where the force acts may be determined by Equation 1.

N = F |cosθ|

(Here. N is the magnitude of the force in the part where the force is applied, F is the magnitude of the applied force, and θ is the angle in the direction in which the force acts with respect to the horizontal plane.)

In Equation 1, when the value of F is constant, the value of N may increase as the variable θ decreases. When the angle θ is in the range of 0° or more to 90° or less, as the value of θ decreases, the magnitude N of the force at the point where the force acts may increase. That is, as the angle θ becomes smaller, the loss of force can be reduced.

Therefore, when the auxiliary guide bar 1241 moves upward, it is possible to move the moving plate 1231 forward with a relatively small force. That is, the movable plate 1231 is linked to the upward movement of the auxiliary guide bar 1241 , and the movable plate 1231 can come forward along the formation direction of the slit 1231a even with a relatively small force. Accordingly, it is possible to easily remove the foreign material P with a relatively small force by reducing the loss of force.

On the other hand, the process of removing the foreign material by the removal unit in the transport device according to the second embodiment of the present invention will be described below while explaining the transport method according to the second embodiment.

The first crushing protrusion 1363 may be provided in plurality, coupled to the outer circumferential surface of the first central body 1362, and may be disposed to be spaced apart from each other by a predetermined interval in the intersecting direction. For example, the first crushing protrusion 1363 may be formed in a concave-convex structure along the circumference of the first central body 1362 . That is, the first crushing protrusion 1363 may have a protruding portion and a recessed portion alternately formed. The first crushing protrusion 1363 may rotate clockwise together with the first central body 1362 .

The second crushing member 1370 rotates in the opposite direction (eg, counterclockwise) to the first crushing member 1360 through the power of the second driving member 1350b, and applies an impact to the foreign material P during rotation. It is possible to pulverize the foreign material (P) into relatively small particles. The second crushing member 1370 may be disposed in parallel with the first crushing member 1360 based on the transport direction. That is, the second crushing member 1370 may be disposed at the same height as the first crushing member 1360 and spaced apart from each other by a predetermined interval in the transport direction. The second grinding member 1370 may include a second connecting shaft 1371 , a second central body 1372 , and a second grinding protrusion 1373 .

The second connecting shaft 1371 is formed in a cylindrical shape extending in the cross direction, and may be respectively connected to the second driving member 1350b and the second central body 1372 . The second connecting shaft 1371 may transmit the power of the second driving member 1350b to the second central body 1372 .

Here, the second grinding protrusions 1373 may be alternately disposed with the first grinding protrusions 1363 . That is, the second crushing projections 1373 may be disposed between the first crushing projections 1363 spaced apart in the cross direction. For example, the second crushing protrusion 1373 may be formed in a concave-convex structure along the circumference of the first central body 1362 . The second grinding protrusion 1373 may rotate counterclockwise together with the second central body 1362 . Accordingly, the second crushing member 1370 may rotate in a direction engaged with the first crushing member 1360 .

That is, it includes a case in which the foreign material (P) is crushed in the transport device (1000).

9 is a flowchart illustrating a transport method according to embodiments of the present invention. A transport method according to embodiments of the present invention will be described with reference to FIGS. 1 to 9 . Hereinafter, in describing the transport method, the same operation of the first embodiment, the second embodiment, and the third embodiment will be described together, and the different operations will be described separately for each embodiment.

Referring to FIGS. 1 and 5 ( a ), the object 10 may be seated on the transport device 1000 ( S110 ). That is, it is possible to perform the operation of seating the object 10 on the seating member 1150 of the transport device 1000 with the overhead crane 20 . The hanging member 13 of the object 10 may be supported by being caught on the hook of the overhead crane 20 . In order to seat the object 10 on the transport device 1000 , the object 10 may be positioned above the rectangular hole 1113 of the transport device 1000 by using the overhead crane 20 .

Then, when the overhead crane 20 moves the object 10 to the lower side, the container member 11 of the object 10 is located in the hole 1113, and the protruding member 12 of the object 10 is a transport device ( 1000) may be seated on the mounting member 1150. At this time, at least a portion of the removal unit 1200 may be moved by the load of the seated object 10 . That is, the process of seating the object 10 on the seating member 1150 and the process of operating the removal unit 1200 may be simultaneously performed.

Meanwhile, in the process in which the object 10 is seated, the metal fixed to the outer circumferential surface of the object 10 may fall to the upper wall 1114 adjacent to the seating member 1150 . Alternatively, the molten material inside the object 10 may be scattered and splashed onto the upper surface of the body member 1110 . At this time, the current and the melt may mainly splash toward the upper wall 1114 adjacent to the mounting member 1150 . Accordingly, foreign substances P may be accumulated on the upper wall 1114 adjacent to the seating member 1150 .

Referring to FIGS. 3(a) to 3(c) and 5(b), the object 10 may rotate by pressing the transmission member 1220 downward. That is, the first body 1221 of the transmission member 1220 is moved downward by the load of the object 10 , the second body 1222 is rotated counterclockwise, and the front side of the transmission member 1220 is The guide bar 1223 coupled to the end may be moved upward. That is, the transmission member 1220 may seesaw motion with the first support bar 1211 as a rotation center.

When the guide bar 1223 is moved upward, the guide bar 1223 may apply upward force to the moving plate 1231 of the removal member 1230 . At this time, the guide bar 1223 may be moved upward along the inclined direction of the slit 1231a penetrated, and the movable plate 1231 may be brought forward. That is, by vertically moving the guide bar 1223 while being fixed to the second body 1222 , the moving plate 1231 can be advanced in the transport direction. At this time, the removal plate 1232 of the removal member 1230 also moves forward together, and it is possible to push the foreign material P accumulated on the upper surface of the transport device 1000 ( S120 ). That is, the removal plate 1232 may be horizontally moved along with the foreign material P along the upper surface of the transport device 1000 . Here, the horizontal movement may be moving in the transfer direction, which is the direction in which the transport device 1000 moves along the rail 30 . That is, by moving the removal member 1230 in the transport direction, the foreign material P can be pushed in the transport direction.

Meanwhile, while the moving plate 1231 moves forward, the elastic body 1231b disposed in the slit 1231a may be compressed and contracted by the guide bar 1223 .

Here, the moving plate 1231 may be moved to the front end of the first area 1131 of the second space 1130 based on the transfer direction, and the removal plate 1232 may be moved to the second space 1130 of the second space 1130 . 2 It is possible to move to the front end of the region 1132 . Accordingly, the foreign material P rides on the guide member 1330 and may fall into the first space 1120 in which the crushing unit 1300 is disposed.

On the other hand, in the second embodiment of the present invention, as shown in FIGS. 6 and 7 , when the object 10 moves downward by pressing the first body 1221, the second body 1222 is rotated counterclockwise. may be rotated to move the end of the second body 1222 upward. At this time, the auxiliary transmission member 1240 connected to the end of the second body 1222 may move upward together, and the auxiliary guide bar 1241 provided at the upper end of the rear side of the auxiliary transmission member 1240 may move upward. . Accordingly, a force can be applied upward to the moving plate 1231 into which the auxiliary guide bar 1241 is inserted, and the auxiliary guide bar 1241 is moved upwardly along the inclined direction of the penetrated slit 1231a, and the moving plate (1231) and the removal plate 1232 can be advanced. Accordingly, the foreign material P accumulated on the upper surface of the transport device 1000 may be pushed toward the crushing unit 1300 .

Thereafter, the transport device 1000 may be moved (S130). That is, the transport device 1000 may be pulled forward by advancing a train (not shown) disposed in front of the transport device 1000 on the rail 30 . Accordingly, the wheel 1140 rotates, and the transport device 1000 may be advanced in the transport direction. At this time, the crushing unit 1300 may rotate together by the rotating wheel 1140 . That is, the process of moving the transport device 1000 and the process of operating the crusher 1300 may be simultaneously performed.

4 and 5 (c), it is possible to crush the pushed out foreign material (P) (S140). The crushing member 1310 may be rotated together in conjunction with the rotation of the wheel 1140 . More specifically, the wheel 1140 , the shaft 1321 , and the first gear may be rotated at the same time. In this case, the second gear meshed with the first gear may rotate, and the second gear 1323 may transmit a rotational force to the crushing member 1310 . Accordingly, the crushing member 1310 rotates to crush the foreign material P pushed out in association with the rotation of the wheel 1140 . That is, by applying an impact to the falling foreign material P, it is possible to pulverize the foreign material into relatively small particles.

On the other hand, in the third embodiment of the present invention, as shown in FIG. 8 , falling foreign substances P are introduced between the first crushing member 1360 and the second crushing member 1370 rotating in opposite directions. can In this case, the first crushing member 1360 and the second crushing member 1370 may be rotated by separately generating power. That is, the detection sensors provided in each of the first driving member 1350a and the second driving member 1350b detect the rotation of the wheel 1140 , and in response to the detection, the first driving member 1350a and the second driving member 1350a and the second driving member 350b may generate power, and the generated driving force may be provided to the first crushing member 1360 and the second crushing member 1370, respectively. Accordingly, the first crushing protrusion 1363 and the second crushing protrusion 1373 rotate in a meshing direction to compress the foreign material P to be crushed into relatively small particles. Meanwhile, the first crushing member 1360 and the second crushing member 1370 may be operated by a remote device such as a remote control or a switch.

Thereafter, the pulverized foreign material P may be recovered using the recovery member 1340 and the recovered foreign material P may be classified. That is, it is possible to classify the pulverized foreign material P introduced into the recovery member body 1341 . At this time, the metal material may be extracted from the recovered foreign material P by using the magnetic force of the magnetic body 1342 .

Thereafter, the transport device 1000 may be stopped. That is, it is possible to gradually reduce the moving speed of the vehicle and stop the transport device 1000 .

Thereafter, the object 10 may be separated from the transport device 1000 to return the removal unit 1200 to its original position. Here, the process in which the removal unit 1200 returns to its original position may be performed in the reverse order of the process in which the removal unit 1200 horizontally moves to push the foreign material (P). Here, as the contracted elastic body 1231b is extended, the guide bar 1223 may be pushed, and thus the movable plate 1231 and the removal plate 1232 may move backward.

On the other hand, when the transport device 1000 is stopped, the operator can separate the recovery member body 1341 from the body 1100 and divide it into crushed foreign substances P and a metal material. That is, the collecting member body 1341 may be turned over to separately collect the foreign material P pulverized into relatively small particles, and the metal material attached to the magnetic body of the recovery member body 1341 may be separately collected.

In this way, even if foreign substances are accumulated in the transport device, the foreign substances can be removed from the upper surface of the transport device by the removal unit, and the removed foreign substances can be crushed. Accordingly, it is possible to stably perform the operation of loading the object on the transport device and the operation of transporting the object. Accordingly, the efficiency of the operation of carrying the object can be improved.

As such, although specific embodiments have been described in the detailed description of the present invention, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims to be described below as well as the claims and equivalents.
