Description

TRANSPORTING APPARATUS

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transportation apparatus, and more particularly, to a transportation apparatus that can improve the efficiency of work by measuring a height and a tilting angle of a transportation article.

Generally, a ladle containing melts such as molten iron or molten steel is carried by an overhead crane having sovereignty and coercion. When these melts are transferred to the ladle or tilted to the ladle, the operator activates the overhead crane and tilts the ladle only with the work of sovereignty and courage.

However, since it tilts the ladle only with the work of sovereignty and courage, it can not measure the exact tilt angle of the ladle when tilting the ladle. Therefore, depending on the skill and condition of the operator, the tilting angles of the lasers can be changed each time. For example, the unevenness of the ladle tilting angle during the disposal work may not completely remove the residue in the ladle, thus degrading the quality of the molten steel produced in the providing process. Also, if the tilting angles of the lasers are not known and overcorrected, the lasers may overturn and cause large equipment accidents.

Conventionally, a tilt angle measuring apparatus of lasers as shown in Korean Patent Publication No. 10-1228779 was used. However, since measurement is carried out with a separate measuring gear, there is a possibility that the mounting is difficult and the practicality is low. Also, if thermal deformation occurs or breaks due to materials such as hot molten steel in the ladle, the accuracy of the measured value may be reduced.

FIG.

First, the overall structure of the transportation apparatus 100 will be described in order to understand the present invention. 1, a transportation apparatus 100 according to an embodiment of the present invention includes a frame 180, a first trolley 126, a second trolley 136, a first power generator 121, a second power generator 131, a first wire 124, a second wire 134, a main hook 125, a servo hook 135, a first sensing unit 151, a second sensing unit 152, . In addition, the transport apparatus 100 may include a first wire drum 122, a second wire drum 132,

The frame 180 is formed to extend in the longitudinal direction. At both ends of the frame 180, a traveling wheel may be provided, and the frame 180 may be disposed on the traveling rail so as to be movable forward and backward. The first guide rail 181 and the second guide rail 182 may be formed at different heights along the extending direction of the frame 180 on the top or inside of the frame 180. However, the shape, structure, and position of the frame 180 are not limited to these, and may vary.

The first trolley 126 extends in the horizontal direction and can support the first wire drum 122 and the first power generator 121 at an upper portion thereof. In addition, the first trolley 126 may be provided at a lower portion thereof with a moving wheel so as to be movable in a direction intersecting the moving direction of the frame 180 on the first guide rail 181. Accordingly, the ladle 200 supported by the first trolley 126 can be moved together with the movement of the first trolley 126. However, the structure and shape of the first trolley 126 are not limited to this and may vary.

The first wire drum 122 may be formed in a cylindrical shape and may be disposed on the upper side of the first trolley 126. A pair of first wires 124 may be connected to both ends of the first wire drum 122 along the circumference. The first wire drum 122 may be connected to a first power device 121 that provides a rotational force to wind or unwind the first wire 124 connected to the first power device 121 while rotating according to the operation of the first power device 121. At this time, the first power device 121 may be a motor. One end of the first wire 124 may be connected to a pair of main hooks 125 disposed below the first trolley 126 and formed in a hook shape. Thus, the ladle 200 held by the pair of main hooks 125 can be moved up and down by the operation of the first power device 121. [

The second trolley 136 may extend in the horizontal direction to support the second wire drum 132 and the second power generator 131 at an upper portion thereof. In addition, the second trolley 136 may be provided under the second trolley 136 with a movement wheel so as to be movable in a direction intersecting the movement direction of the frame 180 on the second guide rail 182. However, the structure and shape of the second trolley 136 are not limited to this, and may vary.

The second wire drum 132 may be formed in a cylindrical shape and may be disposed above the second trolley 136. The second wire 134 may be connected along the circumference of the second wire drum 132. The second wire drum 132 may be connected to a second power generator 131 that provides a rotational force to wind or unwind the second wire 134 connected to the second power drum 131 while rotating. At this time, the second power device 131 may be a motor. One end of the second wire 134 may be connected to a bobbin hook 135 disposed below the second trolley 136 and formed in a hook shape. The bobbin hook 135 can be hooked on the lower portion of the ladle 200. Therefore, the lower portion of the ladle 200 supported by the main hook 125 can raise or lower the tie hook 135 or adjust the tilting angle of the lower ladle 200. However, the structure and shape of the second wire drum 132, the second power generator 131, and the bobbin hook 135 are not limited to this, and may vary.

At this time, the second guide rail 182 supporting the second trolley 136 may be disposed at a lower position than the first guide rail 181. Therefore, the second trolley 136 can pass through the first trolley 126 and pass therethrough, so that when the trolley 200 is tilted, the first trolley 126 and the second trolley 136 are spaced apart from each other, Can be overlapped. However, the positions where the first trolley 126 and the second trolley 136 are disposed or moved are not limited thereto and may vary.

The first sensing unit 151 measures the length of the first wire 124 or the distance from the first wire drum 122 to the main hook 125. The first sensing unit 151 may be provided at one side of the first wire drum 122. For example, to measure the length of the first wire 124, the length of the first wire 124 may be measured proximate the portion of the first wire drum 122 where the first wire 124 is wound . In addition, the first sensing unit 151 may include at least one of various sensors capable of measuring a distance, such as a resolver or an ultrasonic sensor. Thus, the position of the ladle 200 supported by the first trolley 126 can be measured. However, the position where the first sensing unit 151 is disposed is not limited to this, and may be various.

The second sensing unit 152 measures the length of the second wire 134 or the distance from the second wire drum 132 to the bobbin hook 135. The second sensing unit 152 may be provided on one side of the second wire drum 132. For example, to measure the length of the second wire 134, the length of the second wire 134 may be measured in proximity to the portion of the second wire drum 132 where the second wire 134 is wound . Also, the second sensing unit 152 may include at least one of various sensors that can measure the distance, such as the first sensing unit 151. Accordingly, the measured value of the second sensing unit 152 and the measured value of the first sensing unit 151 can be compared. However, the position where the second sensing unit 152 is disposed is not limited to this, and may be various.

Hereinafter, the structure of the controller 160 will be described in detail.

2, a controller 160 according to an embodiment of the present invention includes a transceiver 161 connected to the first sensing unit 151 and the second sensing unit 152, a transmission / reception unit 161 connected to the first sensing unit 151 and the second sensing unit 152, And an informing unit 163 connected to the computing unit 162. The computing unit 162 includes a computing unit 162, The controller 160 may include a determination unit 164 connected to the operation unit 162 and a control unit 165 connected to the determination unit 164.

That is, the angle of the ladle 200 according to the difference between the distance from the first sensing unit 151 to the main hook 125 to the controller 160 and the distance from the second sensor 152 to the bobbin hook 135 Information about the change is input. Accordingly, the controller 160 may calculate the tilting angle of the ladle 200 based on the values measured by the first sensing unit 151 and the second sensing unit 152. FIG. The tilting angle of the ladle 200 refers to the slope of the vertical axis of the ladle 200 with respect to the extending direction of the first wire 124. The controller 160 may calculate the height of the ladle 200 by subtracting the measured value of the first sensing unit 151 from the height of the first sensing unit 151 to the floor of the workplace. However, the method by which the controller 160 calculates the height and tilt angle of the ladle 200 is not limited to this and may vary.

At this time, the controller 160 is connected to a power supply unit (not shown) for supplying power, and the power supply unit can supply power to the controller 160 when the ladle 200 is touched. Thus, when the ladle 200 is in transit, the height and tilt angle of the ladle 200 can be measured only during the tilt operation of the ladle 200 without measuring the tilt angle of the ladle 200. However, the power supply unit is not limited to this, and power can be supplied to the controller 160 at various times.

The transceiver unit 161 is connected to the first sensing unit 151 and the second sensing unit 152 to transmit and receive the measured values from the first sensing unit 151 and the second sensing unit 152.

2 or 3, the length of the first wire 124 may be measured through the first sensing unit 151 to determine the distance from the first wire drum 122 to the ladle 200, By subtracting this value from the length from the first wire drum 122 to the work floor, the height of the ladle 200 can be calculated from the floor. For example, when the distance from the first sensing unit 151 to the floor of the work site is D 0 , the length of the first wire 124 is D 1 , the length of the first wire 124 connected to the first wire 124 of the main hook 125, The length of the main hooks 125 is D 3 , the length of the ladle 200 is D 4 , the distance between the main hooks 125 and the ladle 200 is D L , If the length of the portion of said D 5, Dx is the height of the ladle 200 to the bottom of the workplace floor it can be obtained in the following manner. A "Dx = D 0 -D 1 -D L" At this time, D L = D 3 + D 4 -D 5. D 0 is a length that can be known when the transportation apparatus 100 is installed in the workplace, and D 3 , D 4 , and D 5 are constants that can be known by confirming specifications of facilities. Since D 1 is a variable, knowing the length of the first wire 124 as a variable, Dx, which is the height of the ladle 200, can be obtained through the above equation.

2 or 4, the operation unit 162 is connected to the transceiver unit 161 and is connected to the ladle 200 using the measured values of the first sensing unit 151 and the second sensing unit 152. [ The height and tilting angle of the tire can be calculated. That is, if the lengths of the first wire 124 and the second wire 134 are different, the tilting angle of the ladle 200 can be changed. When the calculation unit 162 receives a value of the tilt angle change of the ladle 200 according to the difference between the lengths of the first wire 124 and the second wire 134, The tilting angle of the ladle 200 can be calculated with reference to the extending direction of the first wire 134 through the measured values of the first sensing unit 151 and the second sensing unit 152. For example, let D 1 be the length of the first wire 124, D 2 be the length of the second wire 125, θ be the angle of the ladle 200, and X be D 1 -D 2 . Assuming that D 1 -D 2 = X 1 and θ 2 = 180 when θ 1 = 0, it is assumed that D 1 -D 2 = X 2 and these values can be displayed on the xy graph. The x-axis may be D 1 -D 2 and the y-axis may be the tilting angle of the ladle 200. Then, by interpolating the two points on the xy graph linearly using the interpolation method, a relation of θ = aX + b can be obtained. Since a and b are constant values calculated using given θ 1 , θ 2 , X 1 , and X 2 and X is a variable, an X value is obtained through D 1 -D 2 , The angle &thetas; of the light source 200 can be obtained. However, the calculation method of the calculation unit 162 is not limited to this and may be various.

The notification unit 163 may be connected to the operation unit 162 to notify the operator of the height and tilt angle of the ladle 200 measured by the operation unit 162. Accordingly, the notification unit 163 may include at least one of a visual member (not shown) and a hearing member (not shown). The visual member may display the height and tilt angle of the ladle 200 in a visual manner through the display. The hearing aid can inform the operator of the height or tilt angle of the ladle 200 through voice. Accordingly, the operator can confirm the height and the tilting angle of the ladle 200 through the visual member or the hearing member and can work with precision, thereby improving the work efficiency and productivity. However, the method of notifying the operator of the calculated value in the calculating unit 162 by the notifying unit 163 is not limited to this and may be various.

The determination unit 164 is connected to the operation unit 162 and compares the value calculated by the operation unit 162 with a predetermined value. For example, the determination unit 164 may determine whether the ladle 200 has exceeded a set value of 170 to 175 degrees with respect to the extending direction of the first wire 124 as a reference. That is, since the ladle 200 may be overturned when it exceeds the set value, it is necessary to check whether the ladle 200 exceeds the set value. At this time, the determination unit 164 is connected to the notification unit 163, and can alert the operator through the notification unit 163 when the ladle 200 is tilted above the set value. However, the setting value is not limited to this and may be various.

The control unit 165 may be connected to the determination unit 164 and may be connected to at least one of the first driver 121 and the second driver 131. That is, the control unit 165 controls the operation of the first driver 121 or the second driver 131 according to the determination of the determination unit 164 to prevent the ladle 200 from overturning. For example, when the second driver 131 is operated to raise the bobbin hook 135, the lower portion of the ladle 200 is lifted and the ladle 200 can be tilted. If the value calculated by the operation unit 162 exceeds 170 to 175 degrees, the controller 165 stops the operation of the second driver 131 and prevents the ladder 200 from being tilted above the value have. Thus, it is possible to prevent a large accident that may occur in the workplace, and the efficiency of the work can be improved by reducing the number of accidents. However, the configuration of the controller 160 is not limited thereto, and various modifications are possible.

Hereinafter, the operation of the transportation apparatus 100 according to the embodiment of the present invention will be described.

After completion of casting in the performance factory, it is possible to carry out the operation of discharging the residue and contents in the ladle 200. The transport apparatus 100 may serve to move or tilt the ladle 200. First, the main hook 125 of the transport apparatus 100 can be hooked to the main hook hook 201 of the ladle 200 to transport the ladle 200 to the disposal workshop. Next, in order to tilt the ladle 200, a bobbin hook 135 is hooked on a bobbin hook 202 provided at a lower portion of the ladle 200 to perform preparatory work for tilting the ladle 200 . Next, when raising the coping hook 135, the ladle 200 can be tilted at a predetermined angle around the main hook 125. [ At this time, the power supply unit may supply power to the controller 160 to operate the controller 160. The controller 160 controls the length D 1 of the first wire and the length D 2 of the second wire measured by the first sensing unit 151 and the second sensing unit 152 through the transmission / ) Can be received.

The information input to the transmission / reception unit 161 is transmitted to the operation unit 162. The calculation unit 161 can calculate the height of the ladle 200 through the length D 1 of the first wire. Also, the tilting angle of the ladle 200 can be calculated by subtracting the length of the second wire D 2 from the length D 1 of the first wire. At this time, the tilting angle of the ladle 200 may be an angle at which the ladle 200 is tilted with respect to the extending direction of the first wire 124. The position information on the ladle 200 that is output through the operation unit 162 is transmitted to the notification unit 163. The notification unit 163 can inform the operator of such information by a visual or auditory method. For example, the seventh segment display can tell the operator the height and tilt angle of the ladle 200. Accordingly, the tilting angle of the ladle 200 is not controlled by the skill or condition of the operator, but the tilting angle of the ladle 200 can be tilted with an accurate value, 200) can be prevented from being removed. Accordingly, as the tilting operation of the ladle 200 is standardized according to the numerical value, the amount of the residue that may exist in the ladle 200 after the disposal operation is reduced, so that the quality of the molten steel can be improved.

The information calculated by the calculation unit 162 may also be transmitted to the determination unit 164. The determination unit 164 may compare the information received from the operation unit 162 with a predetermined value. For example, the setting value may be set to a value between 170 degrees and 175 degrees. Then, the determination unit 164 may determine whether the measurement value received from the operation unit 162 exceeds the set value. The determination unit 164 may be connected to the notification unit 163. Accordingly, when the measured value of the operation unit 162 exceeds the set value, the determination unit 164 may warn the operator through the notification unit 163.

Meanwhile, the determination unit 164 may be connected to the controller 165. The control unit 165 may be connected to the first driver 121 or the second driver 131 with the main hook 125. [ Accordingly, when the determination unit 164 determines that the tilting angle of the ladle 200 has exceeded the set value, it sends a signal of the controller 165 to control the operation of the first driver 121 or the second driver 131 . That is, the operation of the second driver 131, which serves to tilt the ladle 200, can be stopped to prevent the ladle 200 from tilting above the set value. Thus, it is possible to prevent the overturning of the ladle 200, thereby securing the safety of the operator. In addition, since the work is stopped due to the rollover accident and the repair cost is reduced, the efficiency and productivity of the work can be improved.

Although the transport device has been described above as an example for transporting lanes, the scope of application is not so limited and may be used in transport devices capable of transporting various transports.

Although the present invention has been described in detail with reference to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be defined by the appended claims, as well as the appended claims.
