That is, the first distance sensing unit 100a and the second distance sensing unit 100b constituting the pair of distance sensing units 100a and 100b are supported on the right and left sides of the arm part 21 based on the operator's time. And are respectively provided at both ends of the pair, and generate distance values with a pair of supports 11 and 12 located in front.

Here, the arm portion 21 is installed in the center of the support plate portion 22, the support plate portion 22 is the arm fastening portion 21-1 of the arm portion 21 and the bridge fastening portion 13 of the movable bridge 10 ) Is positioned in a direction perpendicular to the longitudinal direction of the movable bridge 10 on the basis of the fastened state.

The distance signal of the pair of distance detection units (100a, 100b) is confirmed by the operator through the display unit, the operator checks the distance signal so that the distance is consistent with the ideal reference distance and the horizontal state is good (21) To be transported.

More specifically, if the ideal reference distance is 50 cm and the values detected by the first and second distance sensing units 100a and 100b are 56 cm and 52 cm, respectively, the right side of the support plate 22 is moved forward to 52 cm, respectively. After properly adjusting the horizontal state, the guide plate 22 is moved to the front as a whole to guide and control is made in a manner to adjust the reference distance 50cm.

The pair of distance detecting units 100a and 100b may be provided as a magnetic sensor for detecting a distance, but a sensor capable of detecting a distance from the front supports 11 and 12 may be sufficient. no.

The pair of position sensing units 200a and 200b are installed on the front surfaces of both ends of the support plate 22 of the movable bridge construction apparatus 20, like the pair of distance sensing units 100a and 100b, and the support 11 in front. , 12) are respectively detected, and the detected values are generated as position signals and transmitted to the display unit.

That is, the first position detection unit 200a and the second position detection unit 200b constituting the pair of position detection units 200a and 200b support the right and left sides of the arm 21 based on the operator's time. The support members 11 and 12 are installed in the center of the plate part 22 in the state of being spaced apart by a distance, and the presence or absence of the support members 11 and 12 located in front of the plate part 22 is used as a position signal of 'existence' or 'existence'. Each occurs.

Particularly, the first and second position detection units 200a and 200b are paired along the longitudinal direction of the movable bridge 10 based on the state in which the arm fastening portion 21-1 and the bridge fastening portion 13 are fastened. Supports 11 and 12 of each of the inner end is provided facing each other to detect the inner end. Thus, since the first and second position detecting parts 200a and 200b face the inner ends of each of the pair of supports 11 and 12, respectively, the widths corresponding to the distances between the supports 11 and 12 are separated from each other. It is installed as far apart.

The position signals of the first and second position detection units 200a and 200b are checked by the operator through the display unit, and the operator checks the position signals to determine the position of the bridge fastening unit 13 and the arm fastening unit 21-1. The arm 21 is steered so that the center is aligned.

More specifically, the bridge fastening portion 13 is located at the center of the gap between the pair of supports 11 and 12, and the position signals of the first and second position detecting portions 200a and 200b are all ' 'Exists' is the case where the first and second position detection parts 200a and 200b sense the inner ends of the front supports 11 and 12, respectively, so that their centers coincide with each other.

On the other hand, when the position signal of the first position detecting unit 200a is 'absent', the right support 11 is not positioned in front of the first position detecting unit 200a and the pair of supports 11 and 12 are not present. Since the empty space is located between the center of the arm fastening portion 21-1 with respect to the bridge fastening portion 13 with respect to the operator's time is to the left. In addition, when the position signal of the second position sensing unit 200a is 'absent', the left support 12 is not positioned in front of the second position sensing unit 200a, and there is a gap between the pair of supports 11 and 12. Since the space is located, the center of the arm fastening portion 21-1 with respect to the bridge fastening portion 13 is biased to the right based on the operator's time.

The operator checks the position signal, and the guide plate 22 is guided and manipulated in such a manner as to move the support plate 22 in the opposite directions.

If the sensor can detect whether there is enough, the type is not limited thereto.

On the other hand, the pair of position sensing units 200a and 200b may predict the pair of supports 11 and 12 positioned forward by using the positional relationship with the pair of distance sensing units 100a and 100b and the distance signal. The distance may be calculated to detect whether there is a pair of supports 11 and 12 within a predetermined range from the estimated distance, respectively.

 In this case, the pair of position sensing units 200a and 200b detect foreign matters that are placed between the pair of supports 11 and 12 or foreign matter present in the space between the pair of supports 11 and 12. It is possible to prevent the occurrence of an 'existent' position signal of an error, thereby improving the accuracy of the induction work.

In a preferred embodiment of the present invention, a pair of distance sensing unit (100a, 100b) and a pair of position sensing unit (200a, 200b) is provided on the front surface of the support plate 22 of the movable bridge construction apparatus 20 However, the provided positions are not limited thereto and may not be positioned on the same line as each other.

The display unit described above transmits the distance signals of the first and second distance detection units 100a and 100b and the position signals of the first and second position detection units 200a and 200b to the operator.

In addition, the display unit further compares the value of the distance signal and the reference distance, and compares the position signal combination, so that the operator must transfer the support plate part 22 on which the arm part 21 is installed, and the bridge fastening part 13. If the distance of the arm fastening portion 21-1 is adjusted to the reference distance, and the horizontal and center coincidence state is good, it is also possible to calculate the desired subsequent transfer information and transmit it to the operator.

Accordingly, the operator can proceed with the mobile bridge recovery operation simply by following the instructions of the display unit.

The display unit may be preferably provided with an LCD, and may further include additional auxiliary display units such as left forward and backward transfer lamps and right forward and reverse transfer lamps providing subsequent transfer information. However, the implementation of the display unit is not limited thereto, and may be implemented in various ways apparent to those skilled in the art.

2 to 4c, the induction method for the mobile bridge construction apparatus according to the preferred embodiment of the present invention will be described in detail. Induction method for the mobile bridge construction apparatus according to the present invention is the first performing process included in the recovery operation of the mobile bridge to transfer the arm portion 21 so that the bridge fastening portion 13 and the arm fastening portion 21-1 are fastened to each other. To induce.

As the recovery operation of the movable bridge begins, the operator moves the arm 21, and as shown in FIG. 4A, the arm portion (in the space between the pair of supports 11 and 12 of the movable bridge 10 as appropriate) is shown. Moving 21), the induction work begins.

First, the first and second distance detection units 100a and 100b sense the distances to the front supports 11 and 12 and generate first and second distance signals, respectively (s100). It is determined whether the value of the first and second distance signals falls within a reference distance range that is added to or subtracted from a predetermined predetermined value from the reference distance that is the ideal distance (s150). Instructs the movement of the support plate 22 provided with the arm portion 21 (s200).

For example, assuming that the reference distance is 50cm and the reference distance range is 48 to 52cm, if the value of the first distance signal is 56cm and the value of the second distance signal is 52cm, the value of the first distance signal is the reference distance range. The right side of the support plate 22 is moved 6 cm forward from the perspective of the operator to be included in the reference distance.

The indicator may also specifically convey to the operator the content of subsequent transfer operations to move the right side of the support plate 22 forward 6 cm. In this way, the display unit may be implemented to specifically deliver the contents of the subsequent transfer operation. Similarly, the movement instruction after determining whether the first and second distance signals are the same may be implemented.

Next, when the values of the first and second distance signals are all included in the reference distance range, it is determined whether the values are the same (s250), and if the values are different from each other, the display unit 22 supports the values to be the same. Instructs the movement of (S300).

That is, in the above-described example, when the right side of the support plate 22 is moved forward 6 cm, the value of the first distance signal is 50 cm and the value of the second distance signal is 52 cm. If the left side of the plate part 22 is advanced 1 cm and the right side is 1 cm, the values of the first and second distance signals are all equal to 51 cm when it is detected again. This operation is to correct the horizontal state of the arm fastening portion 21-1 with respect to the bridge fastening portion (13).

Based on the contents transmitted through the display unit, the operator advances or retracts the left, right, or the entirety of the support plate part 22 as shown in FIG. 4B, and the arm fastening part 21-21 for the bridge fastening part 13. The support plate part 22 provided with the arm part 21 is conveyed so that the distance and horizontal conditions of 1) may be satisfied.

Thereafter, the first position detecting unit 200a detects the presence of the front support 11 and generates a first position signal (S350). Then, it is determined whether the value of the first position signal is 'exists' (s400), and when the value of the first position signal is not 'existent', that is, 'existent', the front of the first position detection unit 200a. Since the space between the supports 11 and 12 is located in the display unit, the display unit instructs the right side movement of the support plate 22 (S450).

In this case, the display unit may be provided to instruct the movement of the right side until the first position signal of the first position sensing unit 200a changes to 'existence'. This may be equally implemented even in the case of the instruction of left shift described later.

On the other hand, if the value of the first position signal is present, the second position detection unit 200b detects the presence of the support 12 in front and generates a second position signal (s500). It is determined whether the value of the second position signal is 'exists' (s550), and if the value of the second position signal is 'absent', the support 11 and 12 are placed in front of the second position sensing unit 200b. Since the space is located, the display unit instructs the left side movement of the support plate 22 (s600).

Thereafter, when the values of the first and second position signals are all identified as 'present' through this process, that is, as shown in FIG. 2, the bridge fastening portion 13 and the arm fastening portion 21-1 are shown. After the center is guided to match, the display unit displays the fastening signal for the bridge fastening portion 13 and the female fastening portion 21-1 to the operator (s650).

As a result, the induction work is finished and subsequently, as shown in FIG. 4C, after the bridge fastening part 13 and the arm fastening part 21-1 are fastened, a recovery operation for rotating the arm part 21 is performed. It goes on.

As described above, the guidance system for a mobile bridge construction apparatus and the guidance method using the same according to the present invention, a pair of distance sensing unit (100a, 100b) for detecting the distance to the support (11, 12) to generate a distance signal And the display unit for transmitting the distance signal is provided so that the operator can check the distance and horizontal state of the arm fastening portion 21-1 with respect to the bridge fastening portion 13, the inner end of the pair of supports (11, 12) A pair of position sensing units 200a and 200b for detecting a position and generating a position signal are provided, and the display unit transmits the position signal so that the left and right centers of the arm fastening unit 21-1 with respect to the bridge fastening unit 13 match. Since the state can be confirmed by the operator, the operator can easily and quickly proceed with the recovery operation of the movable bridge 10 alone.
