[0039] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0040] Forging refers to a method of applying pressure or impact force to metal materials to make them plastically deform into metal blanks or parts of required geometric shapes and sizes and organizations and properties, so it is also called pressure processing, and the workpiece produced is a forged piece. The forged piece is formed by hot steel ingot through forging and pressing, and some defects exist in the production process. The forged piece is an important blank for various mechanical equipment and boiler vessels. In actual application, it bears high load, and in order to ensure the safe use of the equipment, it is the most practical to detect the forged piece by using detection technology. According to the ultrasonic flaw detection standard "GB / T37400.15 General Technical Conditions for Heavy Machinery Part 15: Nondestructive Testing of Forged Steel Parts", 100% UT (Ultrasonic Testing) detection is carried out, and the quality grade I is qualified.

[0041] The shield of underground construction equipment excavates a section size according to design requirements, and the diameter is 3-25 meters. The excavation diameter, construction conditions and different geological conditions of the shield require that the shield design must be customized and personalized. Therefore, as one of the core parts of the main bearing of the shield, the ring forging has the following main characteristics: large size change, complex cross section and large weight. The large size change is that the diameter is 3-9 meters, the complex cross section mainly reflects various sizes of steps and grooves, and the heaviest weight is 30 tons. The above characteristics bring the following difficulties to the flaw detection of the ring forging:

[0042] (1) The forging blank has various specifications and complex cross sections, and the detection amount is huge. The conventional flaw detection of the ring forging adopts a longitudinal wave straight probe to scan in two directions, including radial detection in the outer circle and axial detection in the cross section. Manual scanning can only step scan in two directions, and the detection efficiency is low. The scanning of 8-9 meter complex ring forging generally needs one shift.

[0043] (2) The ultrasonic flaw detection is highly dependent on the skills and responsibility of the operator, and there are uncertainties such as missed detection, inaccurate defect quantification and inaccurate rating.

[0044] (3) The detection data and results cannot be stored, and the detection process has poor traceability.

[0045] Therefore, manual detection cannot meet the detection needs of batch production of ring forgings, the key parts of bearings, and has become a bottleneck process in production.

[0046] To solve the above technical problems, the present application provides an ultrasonic testing device, which uses a detection container to contain a ring forging and a coupling agent, thereby achieving full water immersion testing. The ring forging is clamped and positioned by a first driving device and a second driving device, and the ring forging is driven to rotate. An ultrasonic testing device is abutted against an end surface of the ring forging and moves along the end surface, and an ultrasonic testing device is abutted against a side surface of the ring forging and moves along the side surface. In this way, through the rotation of the ring forging and the movement of the ultrasonic testing device on the surface of the ring forging, automatic detection in multiple detection directions is achieved, and the efficiency is relatively high. The movement path of the ultrasonic testing device on the surface of the ring forging can be controlled by a control device, and the control device can record detection data and analyze the quantitative and rating of defects according to standard requirements, and finally output a testing report. The second driving device is movably connected to the detection container, and by adjusting the position of the second driving device, the first driving device and the second driving device can clamp and position ring forgings of different diameters, and drive the ring forgings to rotate. Therefore, the ultrasonic testing device can detect ring forgings of different sizes.

[0049] The detection container 100 is used for containing a coupling agent and a ring forging 800. It should be noted that, in order to achieve full water immersion testing, the coupling agent needs to immerse the ring forging 800.

In this way, the first driving device 200 and the second driving device 300 can clamp and position the ring forging 800. Then, the first driving device 200 and the second driving device 300 drive the ring forging 800 to rotate around the axis of the ring forging 800.

One ultrasonic detection device 400 abuts against the end surface of the ring forging 800 and moves along the radial direction of the ring forging 800. The other ultrasonic detection device 400 abuts against the side surface of the ring forging 800 and moves along the axial direction of the ring forging 800.

[0055] The first driving device 200, the second driving device 300 and the ultrasonic detection device 400 are electrically connected with the control device 500.

[0056] In operation, the ring forging 800 is placed in the detection container 100 by using a crane, the detection container 100 is filled with water to immerse the ring forging 800. The second driving device 300 moves towards the first driving device 200 relative to the detection container 100, the second driving device 300 continues to push the ring forging 800 to move towards the first driving device 200 after abutting against the ring forging 800, so that the first driving device 200 and the second driving device 300 can clamp and position the ring forging 800. The cross section of the ring forging 800 to be detected is set in the control device 500, and the control device 500 plans a path. After starting detection, the two ultrasonic detection devices 400 move to the starting position of the path, and the first driving device 200 and the second driving device 300 drive the ring forging 800 to rotate around the axis of the ring forging 800. The ultrasonic detection device steps a certain distance or performs spiral scanning when the ring forging 800 rotates one axis. The control device 500 records detection signals and position signals, analyzes the quantity and grade of defects according to standard requirements, and finally outputs a detection report.

[0057] The ultrasonic detection equipment provided by the embodiment comprises a detection container 100, a first driving device 200, a second driving device 300, at least two ultrasonic detection devices 400 and a control device 500.

Therefore, the detection efficiency of the ultrasonic detection equipment is high.

[0058] Figure 2 The structure diagram of the control device in the ultrasonic detection equipment provided by the embodiment of the application is shown.

[0059] Referring to Figure 2 The control device 500 comprises a computer 510 and an electrically controlled operation table 520.

[0060] Figure 3 The structure diagram of the ultrasonic detection device in the ultrasonic detection equipment provided by the embodiment of the application is shown.

[0061] Referring to Figure 3 The ultrasonic detection device 400 comprises a mechanical arm 410, a detection probe 420 and a detection data transceiver 430. The detection probe 420 is connected with an operation end of the mechanical arm 410, the detection data transceiver 430 is electrically connected with the detection probe 420 and the control device 500.

[0062] Referring to Figure 1As shown in the figure, the ultrasonic detection device further comprises a pump station 600, which is electrically connected with the control device 500 and communicates with the detection container 100. The pump station 600 is used for conveying the coupling agent into the detection container 100 or discharging the coupling agent in the detection container 100, so as to improve the detection efficiency.

[0063] Figure 4 A top view of the detection container and the second driving device 300 in the ultrasonic detection device provided by the embodiment of the present application.

[0064] Referring to Figure 1 and Figure 4 As shown in the figure, the second driving device 300 comprises two first driving assemblies 310 and two first guide rails 320, and the two first driving assemblies 310 are movably connected with the two first guide rails 320 in one-to-one correspondence.

[0065] Among them, the two first guide rails 320 are connected with the inner bottom wall of the detection container 100, the two first guide rails 320 are arranged at intervals, and the extension directions have an included angle, the two first guide rails 320 are located on the same side of the first driving device 200, and one end of the extension direction is close to the first driving device 200, and the other end is close to the side wall of the detection container 100.

[0066] It can be understood that by arranging the first driving device 200, the two first driving assemblies 310 and the two first guide rails 320, a three-point centering method is adopted to fix the detection point, and the structure is relatively simple.

[0067] Figure 5 A structure schematic view of the first driving assembly in the ultrasonic detection device provided by the embodiment of the present application.

[0068] Referring to Figure 5 As shown in the figure, the first driving assembly 310 comprises a moving trolley 311, a first driving member 312, a first transmission member 313, a second driving member 314 and a second transmission member (not shown in the figure), the first transmission member 313 is rotatably connected with the moving trolley 311, the driving shaft of the first driving member 312 is connected with the first transmission member 313, the first transmission member 313 is connected with the first guide rail 320, and the first driving member 312 drives the moving trolley 311 to move along the first guide rail 320 through the first transmission member 313.

[0069] The second transmission member is rotatably connected with the moving trolley 311, the driving shaft of the second driving member 314 is connected with the second transmission member, the second driving member 314 drives the second transmission member to rotate, and the second transmission member is used for abutting against the ring forging 800 and driving the ring forging 800 to rotate.

[0070] In operation, the first driving member 312 drives the first transmission member 313 to rotate, and the first transmission member 313 moves along the first guide rail 320. The second driving member 314 drives the second transmission member to rotate, and the second transmission member abuts against the ring forging 800 and drives the ring forging 800 to rotate by friction.

[0071] In a possible implementation, the first transmission member 313 can be a gear, and the first guide rail 320 can be a toothed rail matched with the gear.

[0072] The first driving member 312 is a servo motor. It can be understood that, when ring forgings 800 of different diameters are detected, the required clamping force is different due to the different structural strength and weight of the ring forgings 800. The first driving assembly 310 can calculate the clamping force value by the output torque of the servo motor, and ensure that the clamping force meets the working condition requirements.

[0073] For example, the toothed rail has a size of 8.3 m x 0.1 m x 0.05 m, is made of high-strength 42CrMo material, and has good durability.

[0074] In another possible implementation, the first transmission member 313 can be a roller, and the first guide rail 320 can be a wheel rail.

[0075] In order to protect the ring forging 800 and reduce the abrasion of the ring forging 800, and at the same time improve the friction between the first driving assembly 310 and the ring forging 800, the first driving assembly 310 further comprises a first friction member 315, the first friction member 315 is sleeved on the second transmission member, and the first friction member 315 is used to abut against the ring forging 800 and drive the ring forging 800 to rotate.

[0076] Specifically, the first friction member 315 can be a rubber sleeve, and the material of the rubber sleeve can be polyurethane.

[0077] In order to improve the guiding effect of the first driving assembly 310, the second driving device 300 further comprises two guiding assemblies 330, the two guiding assemblies 330 are arranged in one-to-one correspondence with the two first guide rails 320, the guiding assembly 330 comprises two second guide rails 331, the two second guide rails 331 are located on opposite sides of the corresponding first guide rail 320 and are arranged in parallel with the corresponding first guide rail 320, and the moving trolley 311 is rollingly connected with the second guide rail 331.

[0078] For example, the guide rail has a size of 8.1 m x 0.15 m x 0.1 m x 0.05 m, is a standard 50 steel rail, and is made of high-strength 45Mn material, and has good wear resistance.

[0079] In a possible implementation, the mobile trolley 311 comprises a trolley body 3111 and at least two guide wheels 3112, the at least two guide wheels 3112 are rotationally arranged on opposite sides of the trolley body 3111, the spacing between the guide wheels 3112 on the two sides is equal to the spacing between the two second guide rails 331 in the same guide assembly 330, and the guide wheels 3112 are in rolling connection with the second guide rails 331.

[0080] Specifically, referring to Figure 5 As shown in the figure, the number of guide wheels 3112 can be four, and the four guide wheels 3112 are symmetrically arranged on opposite sides of the trolley body 3111.

[0081] Referring to Figure 1 and Figure 4 As shown in the figure, in order to reduce the friction between the ring forging 800 and the detection container 100, the second driving device 300 further comprises a plurality of support assemblies 340, each support assembly 340 is located on the same side of the first driving device 200, the extension direction of each support assembly 340 is different, and one end of each support assembly 340 along the extension direction is close to the first driving device 200, and the other end is close to the side wall of the detection container 100.

[0082] Specifically, the support assembly 340 comprises a plurality of support pieces 341 arranged at intervals along the extension direction, and the support piece 341 is in rolling connection with the inner bottom wall of the detection container 100.

[0083] Specifically, the support piece 341 can be a universal ball.

[0084] Exemplarily, the universal ball is a SP-150 precision heavy load universal ball, the overall size is φ240mm*300mm, the ball diameter is 150mm, and the single body load is 6t.

[0085] It can be understood that the support pieces 341 are arranged in a radial manner, which is beneficial to increase the number of contacts between the support pieces 341 and the ring forging 800 and increase the contact area between the support pieces 341 and the ring forging 800.

[0086] Figure 6 The structure diagram of the second driving assembly in the ultrasonic detection equipment provided by the embodiment of the present application is shown.

[0087] Referring to Figure 6As shown, the first driving device 200 includes two second driving assemblies 210 arranged at intervals, and each second driving assembly 210 includes a connecting piece 211, a third driving piece 212, a third transmission piece (not shown in the figure) and a second friction piece 213. The connecting piece 211 is connected with the inner bottom wall of the detection container 100. The third transmission piece is rotationally connected with the connecting piece 211. The driving shaft of the third driving piece 212 is connected with the third transmission piece. The second friction piece 213 is sleeved on the third transmission piece. The third driving piece 212 drives the second friction piece 213 to rotate through the third transmission piece. The second friction piece 213 is used for abutting against the ring forging 800 and driving the ring forging 800 to rotate.

[0088] It can be understood that, compared with one second driving assembly 210, two second driving assemblies 210 can increase the clamping force on the ring forging 800 and increase the driving capacity on the ring forging 800. The second friction piece 213 has the same effect as the first friction piece 315, and details are not described herein.

[0089] Figure 7 A structural schematic diagram of a first driving assembly and a detection positioning device in an ultrasonic detection equipment provided by the embodiment of the present application is shown in the figure, Figure 8 A use state schematic diagram of a first driving assembly and a detection positioning device in an ultrasonic detection equipment provided by the embodiment of the present application is shown in the figure.

[0090] Referring to Figure 7 and Figure 8 As shown in a possible implementation manner, the ultrasonic detection equipment provided by the present application further includes a detection positioning device 700. The detection positioning device 700 includes a positioning piece 710, a first detection piece 720 and a second detection piece 730. One of the first detection piece 720 and the positioning piece 710 is connected with the first driving assembly 310, and the other is used for being connected with the ring forging 800. The first detection piece 720 is configured to detect the positioning piece 710.

[0091] The second detection piece 730 is connected with the second driving piece 314. The second detection piece 730 is configured to detect the rotation speed of the second driving piece 314. The first detection piece 720 and the second detection piece 730 are both electrically connected with the control device 500.

[0092] It should be noted that the number of the detection positioning device 700 is one. The detection positioning device 700 can be arranged on any one of the two first driving assemblies 310.

[0093] Specifically, the second detection piece 730 is an encoder. The first detection piece 720 is a proximity switch. The positioning piece 710 is a patch.

[0094] In operation, the flaw detection result and the position of the ring forging 800 are basically fitted to quickly locate the approximate area of the defect. Since the ring forging 800 is placed on the universal ball, the friction coefficient is small, and the clamping force ensures that the first friction member 315 is in complete contact with the ring forging 800, and the relative movement of the two can be ignored. The linear speed of the ring forging 800 is monitored by the encoder, and then the running distance of the ring forging 800 is calibrated. A sticker is pasted at the starting position of rotation, and the transmission and reception signals of the proximity switch are used to determine the time for one rotation, which is verified with the running distance of the workpiece to basically locate the position of the defect.

[0095] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
