Description

Technical Field

[0001] The utility model relates to the field of spiral welded pipe processing, in particular to an online phased array ultrasonic detection workstation for spiral welded pipe welds. Background Technique

[0002] As a new non-destructive testing technology, phased array ultrasonic has been widely used in spiral weld detection due to its unique advantages. The weld of spiral welded pipe is relatively long. Phased array ultrasonic detection has crucial significance in the non-destructive testing of spiral welded pipe welds with advantages such as high efficiency, high accuracy, safety, and environmental protection. Due to the increasing demand for spiral welded pipes, the production volume of spiral welded pipes has increased, resulting in a significant increase in the number of phased array ultrasonic detections for welds.

[0003] Traditional ultrasonic testing uses a handheld ultrasonic testing device. First, the weld surface is coated with ultrasonic coupling agent, and then the handheld ultrasonic device is used to detect the weld.

[0004] However, traditional ultrasonic testing has the following drawbacks:

[0005] 1). Since the weld of spiral welded pipe is relatively long, the efficiency of manual detection is too slow. For example, for the weld of an 18-meter spiral welded pipe, the detection time requires 90 minutes, showing very low efficiency.

[0006] 2). Traditional ultrasonic uses ultrasonic coupling agent for coupling. After the detection is completed, it is difficult to remove the coupling agent. Even the coupling agent adheres to the surface of the welded pipe and reacts, causing difficult-to-remove mottles on the surface of the welded pipe, affecting the appearance quality of the welded pipe.

[0007] 3). Traditional ultrasonic uses one probe with only one incident angle, making it difficult to detect in all directions and prone to missed detection. Content of the Utility Model

[0008] The utility model aims at the above problems and provides an online phased array ultrasonic detection workstation for spiral welded pipe welds with simple structure, convenient operation, and improved reliability.

[0009] The technical solution of the utility model is: an online phased array ultrasonic detection workstation for spiral welded pipe welds, including a workbench, a phased array device, a handheld scanning device, a water storage tank, an arc-shaped water tank, and at least two roller racks.

[0010] The arc-shaped water tank is arranged on the outer support frame of the water tank, and the roller racks are arranged on the arc-shaped water tank. The roller racks are used to place spiral welded pipes.

[0011] The workbench is horizontally movable and arranged on one side of the arc-shaped water tank.

[0012] The phased array device and the water storage tank are respectively arranged on the workbench.

[0013] A pair of probes, an encoder and a water pipe are arranged on the handheld scanning device. The probes and the encoder are respectively connected to the phased array device, and the water pipe is connected to the water storage tank through a water pump.

[0014] It further includes a waveform display large screen which is arranged on the workbench and connected to the phased array device.

[0015] It further includes a height adjustment frame which corresponds to the roller frame one by one, and the height adjustment frame is arranged between the roller frame and the arc-shaped water tank.

[0016] One side of the outer support frame of the water tank is provided with a pair of parallel workbench guide rails, and the workbench is slidably connected to the pair of workbench guide rails.

[0017] The handheld scanning device includes a sliding left support, a cross beam and a sliding right support. The cross beam is connected between the sliding left support and the sliding right support, and pulleys are arranged at the bottoms of the sliding left support and the sliding right support.

[0018] A pair of probes, an encoder and a water pipe are respectively arranged on the cross beam.

[0019] The probe selects a 10L32 - A10 phased array probe.

[0020] In the working process of the present utility model, when the handheld scanning device is placed on the spiral welded pipe to detect the weld seam, the encoder and the probe are directly connected to the phased array device; the water in the water storage tank is transmitted to the handheld scanning device through the water pump by the water pipe. When detecting, the water pump switch is turned on to start delivering water, which serves as the coupling agent for detection.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] As shown in the present invention Figures 1-3 A phased array ultrasonic on-line detection workstation for spiral welded pipe welds includes a workbench 1, a phased array device 2, a handheld scanning device 3, a water storage tank 4, an arc-shaped water tank 5, and at least two roller racks 6.

[0031] The arc-shaped water tank 5 is arranged on the outer support frame 7 of the water tank, the roller rack 6 is arranged on the arc-shaped water tank 5, and the roller rack 6 is used to place the spiral welded pipe 8.

[0032] The workbench 1 is horizontally movable and arranged on one side of the arc-shaped water tank 5.

[0033] The phased array device 2 and the water storage tank 4 are respectively arranged on the workbench.

[0034] A pair of probes, an encoder, and a water pipe are provided on the handheld scanning device 3. The probes and the encoder are respectively connected to the phased array device 2, and the water pipe is connected to the water storage tank 4 through a water pump.

[0035] In the operation of the present utility model, the handheld scanning device is placed on the spiral welded pipe. When detecting the weld seam, the encoder and the probes are directly connected to the phased array device; the water pipe conveys the water in the water storage tank to the handheld scanning device through the water pump. When detecting, turn on the water pump switch to start delivering water, which serves as the coupling agent for detection.

[0036] The data detected by the probes and the encoder on the handheld scanning device are transmitted to the phased array device.

[0037] The detection work of the present utility model is safe, reliable, economical, and feasible; the coupling agent is pure water, which avoids the mottling problem of the welded pipe and improves the appearance quality of the welded pipe.

[0038] The coupling agent used in phased array ultrasonic testing is clean water. Water is a fluid. Considering that due to the loss of water, not only the cost is wasted, but also the on-site working environment is affected. Therefore, according to the actual situation, a special arc-shaped water tank is made. This water tank is placed under the spiral welded pipe to be inspected, and the water used for coupling during detection flows into the water tank tooling along the way. This not only improves the on-site environment but also can recycle and discharge the water used in the work, truly achieving safety, environmental protection, and energy conservation.

[0039] Since the weld seam of the spiral welded pipe is spiral, a roller rack is equipped. The roller rack is placed on the height adjustment rack to facilitate the control of the circumferential rotation of the spiral welded pipe.

[0040] In application, there is one motor on each side of the roller rack. The motor is connected to the power supply. When the power supply is turned on, the motor drives the roller rack to rotate circumferentially, and the rotation of the spiral welded pipe drives the other roller racks to rotate circumferentially in a driven manner.

[0041] It also includes a waveform display large screen 9. The waveform display large screen 9 is arranged on the workbench and is connected to the phased array device 2.

[0042] The phased array device synchronously displays the waveform on the waveform display large screen through the data line. The function of the waveform display large screen is to facilitate viewing when there are customers visiting.

[0043] It also includes a height adjustment rack 10. The height adjustment rack 10 corresponds to the roller rack 6 one by one, and the height adjustment rack is arranged between the roller rack and the arc-shaped water tank.

[0044] By setting the height adjustment rack, when the operator detects the weld seam, the height of the operator holding the handheld scanning device is level with the height of the detected spiral weld seam, avoiding the inconvenience caused to the operator by the too high or too low spiral welded pipe.

[0045] One side of the outer support frame of the water tank is provided with a pair of parallel workbench guide rails 11, and the workbench is slidably connected to the pair of workbench guide rails.

[0046] In this way, the workbench can be translated along the direction parallel to the axis of the spiral welded pipe. The mobile workbench and the roller rack are used together to realize the functions of circumferential rotation and longitudinal translation of the spiral welded pipe. In this way, the operator only needs to stand on the mobile workbench and hold the handheld scanning device to realize 100% scanning detection of the spiral weld.

[0047] In addition, for the convenience of the operator's work, a foot-operable control switch is provided on the bottom plane of the mobile workbench and close to the operator, which overcomes the limitation that the operator cannot control the mobile workbench with hands due to holding the handheld scanning device. The foot-operable control switch is a switch for controlling the moving direction of the workbench. The workbench is powered by a battery, and the battery is placed at the bottom of the workbench. The movement of the workbench can also be controlled by a remote control.

[0048] The handheld scanning device includes a sliding left support, a cross beam and a sliding right support. The cross beam is connected between the sliding left support and the sliding right support. Pulleys are provided at the bottoms of the sliding left support and the sliding right support.

[0049] A pair of probes, an encoder and a water pipe are respectively arranged on the cross beam.

[0050] The handheld scanning device in the present utility model is a conventional device and is not shown in the figure. Its structural form is as shown in the patent authorization announcement number CN 217237878U, named "A Handheld Ultrasonic Detection Device for Steel Plates". In this way, it is convenient to move on the spiral welded pipe.

[0051] The probes selected are 10L32-A10 phased array probes. A pair of probes can detect the weld at multiple angles and in multiple directions, avoiding missed detection. In this way, the detection time of the weld is shortened and the detection efficiency of the weld is improved.
