[0002] With the vigorous development of large-capacity and high-parameter generator sets, the steel plates of the main column wing plates of steel structures are getting thicker and thicker. The thicker the steel plate, the greater the possibility of interlayer defects during the rolling process. Ultrasonic phased array detection technology is an emerging non-destructive testing technology that has been developed and widely used in recent years. Its basic principle is to use the array elements of the linear array or surface array arranged in a specified order to excite the ultrasonic pulse signal in a certain time sequence, so that the ultrasonic array is focused at a certain point in the sound field, thereby enhancing the sensitivity of detecting tiny defects in the sound field.

[0003] The probe of the ultrasonic phased array monitoring device is fixed on the steel plate. Although the detection range of the probe is large, when detecting a large range of steel plates, it is still necessary to frequently adjust the detection position. In this process, the probe needs to be repeatedly removed from the steel plate or installed, which is time-consuming and labor-intensive. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Example:

[0023] Reference Figures 1 to 4 The utility model discloses an ultrasonic phased array monitoring device for discontinuous interlayer of steel plate, including a probe 1 electrically connected to the monitoring device body, and also includes two fixing bars 2, a fixing portion 3 is arranged inside the fixing bar 2, and a cross plate 4 is fixedly connected between the two fixing bars 2 and near the head and tail ends of the fixing bars 2, one of the side walls of the cross plate 4 is fixedly connected to two motors 5, the output end of the motor 5 is transmission-connected to a lead screw 6, the lead screw 6 and the two cross plates 4 are both rotatably connected, the outer circumference of the two lead screws 6 is commonly threadedly connected to a screw plate 7, and the probe 1 is detachably connected to one side of the screw plate 7.

[0024] In this embodiment, the bottom surface of the probe 1 is coplanar with the bottom surface of the fixing bar 2. The probe 1 is connected to the screw plate 7 by bolts, which is convenient for the staff to replace the probe 1 according to different situations. After the two fixing bars 2 are fixed to the surface of the steel plate through the fixing part 3, the two motors 5 are started to work, and the motors 5 drive the screws 6 to rotate, and the two screws 6 rotate synchronously to drive the screw plate 7 to move linearly, and the screw plate 7 drives the probe 1 to move linearly, so as to detect different positions on the steel plate.

[0025] In a further preferred embodiment of the present invention, Figure 2 and Figure 3As shown, the fixing part 3 includes a plurality of bottom grooves 31 opened at the bottom of the fixing strip 2, and a suction cup 32 is slidably connected to the lower half of the bottom groove 31, and the suction cup 32 is closed at the top and opened at the bottom. An upper cavity 33 is opened at the upper half of the fixing strip 2, and a plurality of hoses 34 are fixedly penetrated at the lower half of the upper cavity 33, and the hoses 34 pass through the top walls of the corresponding suction cups 32 and partially extend into the suction cups 32, and a driving part 35 is arranged in the upper cavity 33.

[0026] In this embodiment, the hose 34 can be stretched and bent, and will not hinder the vertical movement of the suction cup 32. The suction cup 32 is connected to the lower half of the upper cavity 33 through the hose 34. The suction cup 32 is made of rubber material.

[0027] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, the driving part 35 includes a piston 351 slidably connected to the upper chamber 33, and a plurality of sliding rods 352 are fixedly connected to the top of the piston 351. The sliding rods 352 slide through the top wall of the upper chamber 33 and extend above the fixed bar 2. The tops of the plurality of sliding rods 352 are commonly fixedly connected to a top plate 353, and the top of the fixed bar 2 is fixedly connected to a plurality of electric push rods 354, and the output end of the electric push rod 354 is fixedly connected to the bottom of the top plate 353.

[0028] In this embodiment, when it is necessary to fix the fixing strip 2, the bottom surface of the suction cup 32 is made to fit with the surface of the steel plate, and then a plurality of electric push rods 354 are started to work, the electric push rods 354 drive the top plate 353 to move upward, and the top plate 353 drives the piston 351 to move upward through the sliding rod 352, and negative pressure is generated under the piston 351. Since the suction cup 32 is connected to the lower half of the upper chamber 33, negative pressure is generated in the suction cup 32, and the suction cup 32 is adsorbed on the steel plate, thereby completing the fixation of the fixing strip 2.

[0029] In a further preferred embodiment of the present invention, Figure 3 As shown, a spring 8 is fixedly connected between the top of the suction cup 32 and the inner top wall of the corresponding bottom groove 31 . When the spring 8 is in a natural state, the bottom surface of the suction cup 32 is located below the bottom groove 31 .

[0030] In this embodiment, when fixing the fixing bar 2, the fixing bar 2 is pressed downward so that the suction cup 32 is completely retracted into the bottom groove 31. The suction cup 32 will tightly adhere to the surface of the steel plate under the restoring force of the spring 8 to prevent air leakage between the suction cup 32 and the steel plate.

[0031] In a further preferred embodiment of the present invention, Figure 4As shown, a storage box 9 is fixedly penetrated on the top of the screw plate 7, coupling agent is stored in the storage box 9, a partition 10 is fixedly connected to the lower half of the storage box 9, a discharge pipe 11 is fixedly penetrated on the top of the partition 10, a solenoid valve 12 is fixedly sleeved on the outer peripheral side of the discharge pipe 11, and a plurality of discharge holes 13 are opened on the inner bottom wall of the storage box 9.

[0032] In this embodiment, the top surface of the partition 10 is tilted downward toward one side of the discharge pipe 11. In the initial state, the solenoid valve 12 is closed, and the coupling agent is completely located above the partition 10. When the probe 1 needs to move, the solenoid valve 12 is opened, and the coupling agent falls below the partition 10 through the discharge pipe 11, and falls to the position on the steel plate where the probe 1 will reach through the discharge hole 13, thereby replacing the work of the staff manually applying the coupling agent on the surface of the steel plate at the position of the movement track of the probe 1, which is convenient for the staff to use.

[0033] In the initial movement of the probe 1, the probe 1 does not come into contact with the coupling agent discharged from the storage box 9, so the coupling agent can be applied manually to this area, or the detection result of this area can be ignored.

[0034] In a further preferred embodiment of the present invention, Figure 1 As shown, a distance sensor 14 is fixedly connected to a position corresponding to the storage box 9 on the side wall of the corresponding transverse plate 4 close to the screw plate 7, and the motor 5, the solenoid valve 12 and the distance sensor 14 are electrically connected.

[0035] In this embodiment, the motor 5 and the solenoid valve 12 are electrically connected through the controller, so that the motor 5 and the solenoid valve 12 can be opened or stopped synchronously. In the initial state, the screw plate 7 is located far away from the distance sensor 14. When the motor 5 drives the storage box 9 to gradually approach the distance sensor 14 and is about to contact the distance sensor 14, the distance sensor 14 detects that the distance between the storage box 9 and the storage box 9 is too short, so the solenoid valve 12 and the motor 5 are controlled to stop through the controller, and the ultrasonic monitoring is completed.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
