Description

Technical Field

[0001] The utility model relates to the technical field of weld detection, in particular to a weld detection device for a ship engine frame. Background Technique

[0002] Generally speaking, methods for detecting welding quality and status are divided into destructive testing and non-destructive testing. Among them, non-destructive testing is a method of detecting on the premise that the product integrity or surface of the workpiece does not deform. Representative testing methods include liquid penetration method, magnetic particle flaw detection method, ultrasonic detection method, acoustic emission method, radiation penetration method, eddy current flaw detection method, thermal flaw detection method, holography, etc., which are used to observe surface defects or internal defects of materials.

[0003] The utility model with the application number CN202223442764.5 discloses a non-destructive testing device for ship hull welds, including a mobile vehicle, etc. This utility model is designed with a movable sleeve and a glue outlet tray. By rotating the first screw rod, the position of the movable sleeve can be adjusted, thereby changing the position of the transducer for multiple measurements. By rotating the rotating plate, the glue outlet tray can be rotated to one side of the transducer to apply glue to the transducer, improving the measurement accuracy. When this application is specifically used, the glue outlet tray cannot evenly apply the gel on the ultrasonic transducer, and the gel is likely to fall off during the application process, making the glue application effect worse.

[0030] The following describes a weld detection device for a ship engine frame provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] As shown in Figures 1-5 a weld detection device for a ship engine frame provided by the present utility model includes a detection module 100, a glue application module 200, and a glue scraping module 300. The detection module 100 includes a frame 110, two sliding plates 130 slidably installed inside the frame 110, a bidirectional electric push rod 120 connected between the two sliding plates 130, and an ultrasonic transducer 140 connected to the front side of the sliding plate 130.

[0033] The glue application module 200 includes an L-shaped substrate 210 movably installed at the bottom of the frame 110, a motor 220 connected between the frame 110 and the L-shaped substrate 210, two outer shells 230 connected to the L-shaped substrate 210, a T-shaped glue application plate 240 movably penetrating through the outer shells 230, a tube body 250 inserted into the T-shaped glue application plate 240, a glue storage tank 260 connected to the L-shaped substrate 210, a delivery pump 270 connected to and communicating with the glue storage tank 260, and a connecting pipe 280 connected between the tube body 250 and the delivery pump 270.

[0034] The glue scraping module 300 includes a toothed ring 310 sleeved outside the T-shaped glue application plate 240, a gear 320 meshing with one side of the toothed ring 310, a micro motor 330 connected between the outer shell 230 and the gear 320, and a plurality of scraping plates 340 surrounding the outside of the T-shaped glue application plate 240.

[0035] Furthermore, the T-shaped glue application plate 240, the tube body 250, and the connecting pipe 280 are all made of metal materials, and the interiors of the three are interconnected. With this structural design, the coupling agent in the glue storage tank 260 can be smoothly injected into the interior of the T-shaped glue application plate 240.

[0036] Further, two micro motors 330 are connected in series. The bidirectional electric push rod 120, the ultrasonic energy converter 140, the motor 220, the delivery pump 270, and the micro motors 330 are all electrically connected to an external PLC. The control mode of the present utility model realizes automatic control through the external PLC. The control circuit of the external PLC can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail. Adopting this control mode improves the intelligence of the present device and brings convenience to use.

[0037] Further, a plurality of scrapers 340 are arranged at equal intervals in a circular shape. The inner sides of the scrapers 340 and the inner side of the T-shaped glue application tray 240 are located on the same horizontal plane. With this structural design, when the scrapers 340 rotate following the T-shaped glue application tray 240, they can scrape the coupling agent on the ultrasonic energy converter 140 evenly.

[0038] Embodiment Two:

[0039] Combined with Figure 1 、 3 、4 and Figure 5 As shown, on the basis of Embodiment One, a recycling component 400 is provided on the L-shaped substrate 210. The recycling component 400 includes a material receiving box 410 provided between the L-shaped substrate 210 and the outer shell 230, and a return pipe 420 connected between the glue storage tank 260 and the material receiving box 410. An opening communicating with the inside of the material receiving box 410 is formed on the outer shell 230. By setting the recycling component 400, the coupling agent falling from the inside of the outer shell 230 can be collected uniformly.

[0040] Specifically, the return pipe 420 is arranged in an L shape and penetrates through one side of the L-shaped substrate 210. The material receiving box 410 is internally communicated with the glue storage tank 260 through the return pipe 420. With this structural design, it is ensured that the coupling agent recovered in the material receiving box 410 can be re-injected into the glue storage tank 260, improving the resource utilization rate.

[0041] Embodiment Three:

[0042] Combined with Figure 1 and Figure 4 As shown, in the above embodiment, a sealing ring 500 is installed inside the outer shell 230. The sealing ring 500 is located on one side of the T-shaped glue application tray 240. The inner diameter of the sealing ring 500 is equal to the diameter of the ultrasonic energy converter 140. By setting the sealing ring 500, during the process of applying the coupling agent, the situation that the coupling agent is extruded out of the outer shell 230 is prevented, avoiding resource waste.

[0043] Working principle and usage process of the utility model: When this device is put into actual use, first connect the frame 110 with an external motorized facility (a lift truck), and then the output end of the lift truck drives the slide plate 130 and the ultrasonic energy converter 140 in the frame 110 close to the position of the hull weld. Then, the externally connected PLC starts the motor 220, and the output shaft of the motor 220 drives the L-shaped substrate 210 to rotate. Then, the rotating outer shell 230 sleights on the ultrasonic energy converter 140. Then, start the delivery pump 270, and through the connecting pipe 280 and the pipe body 250 as the medium, the T-shaped glue application plate 240 spits out the coupling agent and smears it on the ultrasonic energy converter 140. Then, start the two micro-motors 330, and the gear 320 drives the T-shaped glue application plate 240 equipped with the toothed ring 310 and the scraper 340 to rotate, thereby achieving the purpose of evenly smearing the coupling agent. After that, control the output shaft of the motor 220 to reverse. Under mechanical transmission, the outer shell 230 opens the ultrasonic energy converter 140, and then the ultrasonic energy converter 140 analyzes the weld.

[0044] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
