Description

Technical Field

[0001] This disclosure generally relates to the field of TOFD scanning technology, and more specifically, to a TOFD scanning electric drive device. Background Technology

[0002] Time-of-Flight (TOFD) is an advanced ultrasonic testing technique primarily used to detect internal defects in materials. TOFD utilizes the diffraction waves generated when ultrasonic waves encounter defects as they propagate through a material. When ultrasonic waves encounter defects such as cracks or inclusions, diffraction waves are generated at the defect tips. These diffraction waves propagate along specific paths to the receiving probe. By analyzing the received diffraction wave signals, information such as the location, size, and shape of the defect can be determined.

[0003] TOFD technology boasts advantages such as high detection sensitivity, accurate positioning, and the ability to detect thick-walled workpieces, making it widely used in fields such as petroleum, chemical, nuclear power, and aerospace. Furthermore, it can be combined with other detection techniques, such as pulse-echo analysis and ultrasonic phased array, to improve the accuracy and reliability of detection.

[0004] TOFD field inspection typically uses manual operation and encoders to record the walking distance to acquire images. Manual operation makes it difficult to move at a constant speed. Too fast a speed will result in image loss, while too slow a speed will result in low inspection efficiency. Utility Model Content

[0005] In view of this, the present disclosure provides a TOFD scanning electric drive device, which aims to solve the problem that in the prior art, TOFD on-site detection is carried out manually, which cannot achieve uniform speed, thus leading to image loss or low detection efficiency.

[0006] To achieve the above objectives, this disclosure provides a TOFD scanning electric drive device, including a drive housing, a motor, a meshing pinion and a large gear, a drive shaft, a drive wheel, a driven wheel, and a connecting assembly. The motor is housed within the drive housing. The pinion and large gear are also housed within the drive housing, and the pinion is fixed to the output end of the motor. The drive shaft is located outside the drive housing and connected to the large gear. The drive wheel and driven wheel are respectively located at both ends of the drive shaft. The connecting assembly is used to fix the TOFD scanning frame to the drive housing.

[0007] Optionally, the connecting assembly includes two fixed rods located above the driving wheel and the driven wheel, respectively. The two fixed rods are connected by a connecting rod. The fixed rod located above the driving wheel is fixed to the drive protective housing. The ends of the two fixed rods near the drive shaft are respectively provided with holes for the drive shaft to pass through. The ends of the two fixed rods away from the drive shaft are respectively fixed to the TOFD scanning frame.

[0008] Optionally, the connecting assembly also includes two locking clips, with the ends of the two fixing rods away from the drive shaft respectively connected to the two locking clips, which secure the TOFD scanning frame by wing nuts.

[0009] Optionally, the TOFD scanning electric drive unit also includes an electrically connected battery pack and speed controller, which are housed within the drive housing, and the speed controller is electrically connected to the motor.

[0010] Optionally, the connecting rod, fixing rod, and locking buckle are all made of aluminum alloy.

[0011] Optionally, the transmission pinion and transmission gear are machined from 20CrMnTi.

[0012] Optionally, both the driving wheel and the driven wheel are magnetic wheels.

[0013] Compared with the prior art, the TOFD scanning electric drive device provided in this disclosure has at least the following advantages:

[0014] In use, the TOFD scanning electric drive unit is fixed to the TOFD scanning frame by locking buckles. The motor drives the drive wheel and driven wheel to move through the transmission pinion and gear, realizing automatic uniform speed scanning.

[0023] One embodiment of this disclosure provides a TOFD scanning electric drive device. For example... Figure 1 and Figure 2 As shown, the TOFD scanning electric drive device includes a drive protective housing 8, a motor 11, a meshing transmission pinion 12 and a transmission gear 13, a drive shaft 3, a drive wheel 1, a driven wheel 2, and a connecting assembly. Figure 1This is a schematic diagram of the structure of a TOFD scanning electric drive device according to one embodiment of the present disclosure, as shown below. Figure 1 As shown, the motor 11, the small transmission gear 12, and the large transmission gear 13 are all housed within the drive housing 8. The small transmission gear 12 is fixed to the output end of the motor 11. The drive shaft 3 is located outside the drive housing 8 and connected to the large transmission gear 13. The driving wheel 1 and the driven wheel 2 are respectively located at both ends of the drive shaft 3. In some examples, the connecting assembly includes two fixing rods 5 and two locking clips 6. The two fixing rods 5 are connected by a connecting rod 4 and are located above the driving wheel 1 and the driven wheel 2, respectively. The fixing rod 5 located above the driving wheel 1 is fixed to the drive housing 8. The ends of the two fixing rods 5 near the drive shaft 3 are respectively provided with holes for the drive shaft 3 to pass through, while the ends of the two fixing rods 5 away from the drive shaft 3 are respectively connected to the two locking clips 6. The locking clips 6 fix the TOFD scanning frame with wing nuts 7. In this way, the TOFD scanning electric drive device can be easily fixed to or removed from the TOFD scanning frame.

[0024] In a preferred embodiment of this disclosure, such as Figure 1 As shown, the TOFD scanning electric drive unit also includes an electrically connected battery pack 9 and speed controller 10. The battery pack 9 and speed controller 10 are housed within the drive housing 8, and the speed controller 10 is electrically connected to the motor 11. The battery pack 9 provides continuous and stable power to the motor 11. The motor 11 transmits power to the drive wheel 1 and the driven wheel 2 through the meshing of the transmission pinion 12 and the transmission gear 13. The speed controller 10 is used to precisely control the rotational speed of the motor 11, thereby adjusting the travel speed of the device to adapt to different detection requirements and ensure the efficiency and consistency of the scanning process.

[0025] In a preferred embodiment of this disclosure, the connecting rod 4, the fixing rod 5, and the locking buckle 6 are all made of aluminum alloy. Their low-alloy, high-strength, and rust-resistant properties fully meet the requirements for long-term use.

[0026] In a preferred embodiment of this disclosure, the transmission pinion 12 and the transmission gear 13 are machined from 20CrMnTi. 20CrMnTi, through carburizing treatment, possesses excellent comprehensive properties and can meet the requirements for long-term use.

[0027] In a preferred embodiment of this disclosure, both the driving wheel 1 and the driven wheel 2 are magnetic wheels. Magnetic wheels can not only adhere well to the drive shaft 3, but also will not damage the surface of the drive shaft 3.

[0028] In one embodiment of this disclosure, the TOFD scanning electric drive device is securely fixed to an existing TOFD scanning frame using locking buckles 6. This ensures the TOFD scanning electric drive device remains stable during scanning, preventing any impact on detection accuracy due to loosening or displacement. The battery pack 9 provides continuous and stable power to the motor 11. The motor 11 transmits power to the driving wheel 1 and driven wheel 2 through the meshing of a small transmission gear 12 and a large transmission gear 13. The TOFD scanning electric drive device moves smoothly along the scanning path. During movement, rollers 16 on the TOFD scanning frame assist in the movement, and the probe 15 on the TOFD scanning frame performs detection. A speed controller 10 is used to precisely control the rotational speed of the motor 11, thereby adjusting the device's walking speed to adapt to different detection requirements and ensure the efficiency and consistency of the scanning process. Through the above design, the TOFD scanning electric drive device achieves automated uniform speed movement, completely avoiding the problems of low efficiency, high labor intensity, and uneven scanning speed in traditional manual operation, ensuring the stability of the scanning process and the reproducibility of results, thereby greatly improving the quality of TOFD maps.
