Description

Smart bridge lifting device with improved stability through micro-motion detection}

The present invention relates to a smart bridge lifting device that improves safety through micro-motion detection. More specifically, the present invention relates to a smart bridge lifting device that precisely lifts the upper structure of the pier and ensures pier safety during bridge repair work through micro-motion detection. It is about a smart bridge lifting device that has improved .

In general, a bridge consists of piers that are spaced at regular intervals to form a lower structure and an upper structure (commonly referred to as a 'bridge') that is placed on top of the piers and allows vehicles or people to pass.

At this time, as the upper and lower structures deteriorate over a long period of time, especially the upper and lower structures deteriorate and repair work is often required. In this case, conventionally, repair work was performed on the upper and lower structures while the upper structure was lifted using a bridge lifting system.

For example, a conventional bridge lifting system was able to lift the upper structure by installing at least one hydraulic jack between the upper structure and the lower structure and controlling the expansion and contraction state (elevation and lowering state) of each hydraulic jack. In this way, after lifting the upper structure using a hydraulic jack, the lower part of the upper structure and the upper part of the lower structure could be repaired. As the upper and lower structures continued to deteriorate for a long time, the upper structure was repaired using a hydraulic jack for a long time. Bridge safety was often a problem because if it was supported, the strength of the support would decrease and a major accident could occur, such as the upper structure collapsing or being deformed.

In particular, there was a problem that safety could not be guaranteed not only for workers performing bridge repair work, but also for vehicles and people passing on the bridge during repair work.

The hydraulic system unit 160 that supplies hydraulic pressure to the hydraulic supply unit 113 is controlled so that the lifting cylinder 112 of the raising unit 110 is raised and lowered equally, so that the same hydraulic pressure is supplied to the main body 111 through the hydraulic supply unit 113.

Hereinafter, additional configurations of the smart bridge lifting device 300, which improves safety through fine motion detection for controlling the bridge lifting device 100 described above, will be described in more detail.

Figure 4 is a diagram illustrating an additional configuration of a smart bridge lifting device that improves safety through fine motion detection according to an embodiment of the present invention.

Referring to FIG. 4, the smart bridge lifting device 300, which improves safety through fine motion detection according to an embodiment, includes a raising/lowering signal receiver 320, a structure deformation diagnosis unit 330, and a structure noise diagnosis unit 340. ), a structure vibration diagnosis unit 350, and a memory 360 may be further included.

In one embodiment, the lifting signal receiver 320 may receive a lifting operation signal and a lifting and lowering stop signal generated when the upper structure 10 is raised and lowered from the lifting device control unit 310.

Before lifting the upper structure 10, the structure deformation diagnosis unit 330 may preset the first lower information of the upper structure 10 that allows the status of the upper structure 10 to be known.

Then, the structure deformation diagnosis unit 330 may receive the second lower information that is a result of monitoring by at least one operation monitoring unit 170 disposed between the upper structure 10 and the lower structure 20, , the deformation state of the upper structure 10 can be diagnosed through comparison of the received second lower information and the preset first lower information.

At this time, the first sub-information and the second sub-information may be video information or image information.

Meanwhile, before lifting the upper structure 10, at least one operation monitoring unit 170 reacts according to the raising and lowering operation signal, the lifting and lowering stop signal, and the timing before and after the bridge repair work to monitor the upper structure 10 for a predetermined time. It is possible to generate second lower information that monitors the lower part of .

In this case, the structure deformation diagnosis unit 330 according to an embodiment reacts according to the time before and after the lifting and lowering operation signal, the lifting and lowering operation signal, and the bridge repair work before raising the upper structure 10, and the operation monitoring unit 170 ), and compare the received second lower information with the preset first lower information to determine whether there is an abnormality in the deformation of the upper structure, and if there is an abnormality, deformation abnormality diagnosis information can be created.

For example, when the second lower information is outside the preset similarity level compared to the first lower information, it is diagnosed that the lower part of the upper structure 10 is deformed, and deformation abnormality diagnostic information can be generated. 2 If the lower information does not deviate from the preset similarity level compared to the first lower information, it can be diagnosed that the upper structure 10 has not fallen or settled.

At this time, the similarity in the preset range refers to the degree of similarity in image pixel units, but is not necessarily limited thereto.

Here, the mentioned at least one operation monitoring unit 170 may be at least one camera 171 disposed between the upper structure 10 and the lower structure 20, or the upper structure 10 and the lower structure ( It may be at least one motion sensor 172 disposed between 20).

In this case, the second lower information may be lower photographed information (video or image information) captured by at least one camera 171 or lower motion information detected by the motion sensor 172, and may be lower than the preset first lower information. The information may be video or image information or motion image information corresponding to the second sub-information.

Meanwhile, at least one operation monitoring unit 170 is disposed between the upper structure 10 and the lower structure 20, for example, adjacent to each bridge lifting device 100 and disposed on the upper part of the lower structure 20. In addition, the deformation (movement) of the lower part of the upper structure 10 can be photographed at a predetermined time when the upper structure 10 is raised and lowered and during the maintenance work period.

In addition, although it has been described as diagnosing deformation of the lower part of the upper structure 10, it goes without saying that deformation of the lower structure 10 can also be a subject of diagnosis.

In one embodiment, the structure noise diagnosis unit 340 may preset a noise standard value that is a standard for diagnosing noise abnormalities that will occur in the upper structure 10 before raising the upper structure 10.

Then, the structure noise diagnosis unit 340 compares the noise measurement value measured using at least one noise detection sensor 180 disposed between the upper structure 10 and the lower structure 20 and a preset noise standard value. Through this, the diagnosis of noise abnormality can be determined.

A plurality of pieces may be disposed anywhere on the upper structure 10 and/or the lower structure 20.

In one embodiment, the structure vibration diagnosis unit 350 may preset a vibration reference value that is a standard for diagnosing vibration abnormalities that will occur in the upper structure 10 before lifting the upper structure 10.

Then, the structure vibration diagnosis unit 350 receives the vibration measurement value measured using at least one vibration detection sensor 185 disposed between the upper structure 10 and the lower structure 20 to diagnose a vibration abnormality. You can judge.

For example, the structure vibration diagnosis unit 350 receives vibration measurements measuring vibration occurring in the upper structure according to the raising/lowering operation signal, the lifting/lowering stop signal, and the timing before and after the bridge repair work from at least one vibration detection sensor 185. It can be received, and if the received vibration measurement value is greater than the preset vibration standard value, vibration abnormality diagnostic information can be generated, and if the received vibration measurement value is less than the preset vibration standard value, it can be diagnosed as normal vibration.

In addition, if necessary, the natural frequencies (frequencies) of each of the upper structure 10 and the lower structure 20 are stored in advance in the lifting device control unit 310, and the frequency measured by the vibration detection sensor 185 is the upper structure ( 10) and the lower structure 20, when vibration equal to the natural frequency of each is detected, the operation of the bridge lifting device 100 can be temporarily stopped. This control operation may be performed by the lifting device control unit 310.

In addition, a vibrator (not shown) may be installed in the upper structure 10 and the lower structure 20, and the frequency measured by the vibration detection sensor 185 is the upper structure 10 and the lower structure 20, respectively. When vibration equal to the natural frequency is detected, the lifting device control unit 310 may temporarily stop the operation of the bridge lifting device 100 and then operate the vibrator.

If the same frequency (frequency) as the natural frequency of the structure continues to occur, even if the vibration is not large, it may be amplified by the resonance phenomenon and cause an accident. However, with the above configuration, such accidents can be prevented in advance.

The mentioned at least one vibration detection sensor 185 is disposed between the upper structure 10 and the lower structure 20, and may preferably be disposed adjacent to each bridge lifting device 100, but is not limited thereto. Alternatively, a plurality of them may be disposed anywhere on the upper structure 10 and/or the lower structure 20.

In this way, the deformation abnormality diagnostic information, noise abnormality diagnostic information, and vibration abnormality diagnostic information generated by the components 330, 340, and 350 may be transmitted to a monitoring device or mobile terminal to be described later.

For example, the displacement detection sensor 190 is installed in each of the upper structure 10 and the lower structure 20 to determine which part of the upper structure 10 and the lower structure 20 is experiencing an abnormality, As a safety measure, the first step is to immediately stop construction and control vehicles and pedestrians. Secondly, after safety diagnosis, reinforcing measures are taken. Then, after lifting restrictions on vehicle and pedestrian traffic, construction can be resumed as a third step. there is.

For example, the structure displacement diagnosis unit 380 receives a lifting/lowering operation signal, a lifting/lowering stop signal, and a displacement measurement measuring the displacement of the upper structure according to the timing before and after bridge repair work from at least one displacement detection sensor 190. If the received displacement measurement value is greater than the preset displacement reference value, displacement abnormality diagnostic information can be generated, and if the received displacement measurement value is less than the preset displacement reference value, the upper structure 10 can be diagnosed as a normal displacement. You can.

Meanwhile, without being limited to the mentioned displacement reference value, the displacement reference value may be a displacement measurement measured from at least one displacement detection sensor 190. In this case, if there is a difference among the displacement measurements, it is judged as an abnormal displacement. Displacement abnormality diagnostic information can also be generated.

The mentioned at least one displacement detection sensor 190 may be disposed on the superstructure 10 and/or the substructure 20, but the lower part and/or substructure 10 of the superstructure 10 at the corresponding location. ) It may be desirable to be placed at the top of the.

Accordingly, the abnormality diagnosis management unit 370 according to one embodiment may further transmit the displacement abnormality diagnosis information generated by the above-described structure displacement diagnosis unit 380 to the network-connected monitoring device 400 or the mobile terminal 410. You can.

In addition, the abnormality diagnosis management unit 370 may further transmit the generated displacement abnormality diagnostic information in the form of an alarm to the monitoring device 400 or the mobile terminal 410, and further transmit the displacement abnormality diagnostic information to the lifting device control unit 310. You can.

In this case, the monitoring device 400 or the mobile terminal 410 receives the displacement diagnosis result, which is the displacement diagnosis result, received from the abnormality diagnosis management unit 370 of the smart bridge lifting device 300, which improves safety through fine motion detection, and its Additional alarm types can be displayed.

On the other hand, the lifting device control unit 310 according to one embodiment is adjacent to the corresponding displacement detection sensor 190 that generated the displacement abnormality diagnosis information received from the abnormality diagnosis management unit 370 among the at least one displacement detection sensor 190. The raising and lowering operation of the bridge lifting device 100 can be adjusted.

For example, assuming that the displacement measurement corresponding to the lower position A of the superstructure 10 is an abnormal displacement and the displacement measurement corresponding to the lower positions B, C, and D of the superstructure 10 are normal displacement, the bridge The lifting device 100 can raise and lower the lower part A of the upper structure 10 to match the normal displacement.

In this way, the reason why the lower part A of the upper structure 10 is adjusted to the normal displacement is because the weight is concentrated on the lifting part 110 of the bridge lifting device 100, which supports a position where the displacement measurement of the upper structure is different. This is because the lifting part 110 cannot normally support the upper structure 10.

As such, in this embodiment, by taking safety measures such as adjusting the raising and lowering of the upper structure 10 at the corresponding position according to the diagnosis of displacement abnormality, it will be possible to prevent the falling and sinking of the upper structure in advance.
