Technical Field

[0001] The present invention relates to the technical field of ultrasonic detection, and in particular to a wear-resistant steel liner defect detection device based on an ultrasonic sensor. Background Art

[0002] The wear-resistant steel liner defect detection device based on ultrasonic sensor is designed to detect defects in wear-resistant steel liner, such as cracks, voids, peeling and other defects, through ultrasonic technology.

[0003] The patent with patent announcement number CN211741162U relates to a device for detecting defects in finished blades of a wind turbine generator set, including an operating table, a controller, a detection instrument, a flipping and clamping mechanism and a translation mechanism; the flipping and clamping mechanism is arranged at both ends of the operating table, the translation mechanism is arranged along the axial direction of the operating table, and the detection instrument is arranged on the translation mechanism and can move along the translation mechanism; the detection instrument includes a signal transmitter and an ultrasonic probe, the output end of the controller is connected to the signal transmitter, and the output end of the ultrasonic probe is connected to the input end of the controller; the flipping and clamping mechanism is arranged at both ends of the operating table, for clamping the wind rotor blades, and can realize the flipping of the blades.

[0005] In view of the deficiencies in the prior art, the present invention provides a wear-resistant steel liner defect detection device based on an ultrasonic sensor, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A wear-resistant steel liner defect detection device based on an ultrasonic sensor includes an operating table, a guide rail is fixedly installed on the top of the operating table; A driving device, the driving device is arranged on the top of the guide rail, and the driving device is used to drive the driving device to move back and forth on the top of the guide rail; A support frame is fixedly installed on the top of the driving device, a hollow tube is fixedly installed between the support frames, a cylinder is slidably installed on the top of the hollow tube, a long plate is fixedly installed on the bottom of the cylinder, and a hydraulic device is provided on the top of the cylinder; An ultrasonic probe is provided at the bottom of the long board and is used to perform ultrasonic testing on items placed on top of the operating table; A sleeve is fixedly installed on the top of the long board, a lifting block is slidingly penetrated on the surface of the long board, a detection roller is rotatably installed on the bottom of the lifting block, an inclined block is slidably installed inside the sleeve, a sliding groove is provided on the surface of the inclined block, a sliding block is fixedly installed on the top of the lifting block, and the sliding block is slidably installed on the inner wall of the sliding groove.

[0007] According to the above technical solution, a lifting vertical rod is slidably installed on the top of the long board, and a fixed block is fixedly installed on the surface of the lifting vertical rod. A limit block is rotatably installed on the side of the fixed block away from the lifting vertical rod. The driving device moves to drive the support frame and the hollow tube to move toward the tail of the steel lining plate. Then the ultrasonic probe performs ultrasonic detection on the steel lining plate, so that during the detection, the ultrasonic probe is as close to the steel lining plate as possible. The bottom of the fixed block is fixedly installed with a limit plate. After the long board moves, the detection roller no longer contacts the steel lining plate. Then the lifting vertical rod moves toward the bottom, driving the fixed block to move toward the bottom. The movement of the fixed block drives the limit block to move toward the bottom. Since the limit block is no longer blocked by the limit plate, a protective device for improving the reliability of the steel lining plate detection result and a mute device for reducing the detection error are provided on the top of the operating table.

[0008] According to the above technical solution, a No. 1 spring is arranged between the lifting block and the long plate, and the limit block is in contact with the hollow tube. The No. 1 spring drives the lifting block to reset when the detection roller is not in contact with the steel liner.

[0009] According to the above technical solution, a No. 2 spring is provided between the lifting vertical rod and the housing, and the inclined surface block contacts the lifting vertical rod. When the inclined surface block no longer contacts the lifting vertical rod, the No. 2 spring drives the lifting vertical rod to reset.

[0010] The top end of the driving member is mounted on the support frame, and the lower end of the driving member is mounted on the support frame, and the lower end of the driving member is mounted on the support frame.

[0011] According to the above technical solution, a No. 1 torsion spring is provided between the rotating rod and the support frame, and the limit rod is in contact with the stop block. When the transmission rod is no longer in contact with the lifting vertical rod, the No. 1 torsion spring drives the rotating rod to reset.

[0012] The cam is fixedly mounted on the inner wall of the driving mechanism, and the cam is fixedly mounted on the outer wall of the driving mechanism, and the cam is fixedly mounted on the outer wall of the driving mechanism.

[0013] According to the above technical solution, a No. 2 torsion spring is arranged between the rotating push rod and the rotating shaft, the rotating push rod is in contact with the rubber ring, and a No. 3 spring is arranged between the rubber ring and the rotating shaft. The No. 2 torsion spring drives the rotating push rod to reset when the rotating push rod stops rotating.

[0014] The present invention provides a wear-resistant steel liner defect detection device based on an ultrasonic sensor. It has the following beneficial effects: (1) This invention drives the support frame and the hollow tube to move toward the tail of the steel lining by moving the driving device, and then the ultrasonic probe performs ultrasonic detection on the steel lining, so that when performing the detection, the ultrasonic probe is as close to the steel lining as possible to prevent incomplete signal reflection due to excessive distance, thereby affecting the accuracy of the detection result and ensuring the reliability of the measurement result. After the long plate moves, the detection roller no longer contacts the steel lining, and then the lifting vertical rod moves toward the bottom, driving the fixed block to move toward the bottom. The movement of the fixed block drives the limit block to move toward the bottom. Since the limit block is no longer blocked by the limit plate, the device can automatically reset after the detection is completed, thereby improving the comfort of the device when in use.

[0015] (2) This invention drives the limit rod to move toward the top by moving the through rod. After the limit rod moves, it no longer contacts the stop block and is no longer blocked, so that the device cannot perform detection before the ultrasonic probe is adjusted. This further ensures the reliability of the measurement data. The limit rod is driven to move toward the bottom by moving the through rod. After the limit rod moves, it contacts the stop block, so that the device can automatically limit and release the limit according to the working status of the ultrasonic probe, thereby improving the degree of automation of the device.

[0016] (3) This invention reduces the noise generated during movement by absorbing the noise generated during movement through sound-absorbing cotton when the driving device moves, prevents excessive noise from causing interference or distortion of the detection signal, and ensures the normal operation of the entire device. The movement of the rubber ring will contact the lifting slider, causing excessive friction between the lifting slider and the silent roller, reducing the rotation speed of the silent roller, so that the device will automatically slow down when the driving device moves too fast, further reducing the noise generated during movement and improving the practicality of the device.
