Description

Technical Field

[0001] The utility model relates to the technical field of weld detection, and specifically discloses a steel structure weld detection device. Background Technique

[0002] When the existing weld detection device detects the welded part of structural steel, it is necessary to spray a coupling agent at the welding position before the ultrasonic probe can be used to detect the weld. Therefore, the detector needs to carry the coupling agent with him, and it is impossible to spray it at any time during the inspection, which is relatively inconvenient to operate. Content of the Utility Model

[0003] In view of the above defects or deficiencies in the prior art, the present application aims to provide a steel structure weld detection device, including a detector body, a connector electrically connected to the outside of the detector body through a connecting wire, and an ultrasonic probe inserted into the outside of the bottom end of the connector. A fixing plate is fixedly sleeved on the outside of the connector, and a spray head located on one side of the ultrasonic probe is fixedly sleeved inside the fixing plate. The inside of the top end of the spray head is communicated with a liquid spraying mechanism fixedly installed on the outside of the detector body. Clamping plates are arranged on both sides of the detector body, and a transparent liquid storage cylinder is clamped inside the clamping plates. A liquid adding pipe is arranged on the outside of the transparent liquid storage cylinder, and a sealing cover is threadedly sleeved on the outside of the top end of the liquid adding pipe.

[0004] Preferably, annular bosses are arranged on the outside of both ends of the transparent liquid storage cylinder.

[0005] Preferably, a breathable film is attached to the inside of the sealing cover.

[0006] Preferably, the liquid spraying mechanism includes a water pump fixedly installed on the outside of the detector body and a connecting pipe communicated with the inside of one end face of the transparent liquid storage cylinder. The water pump is communicated with the connecting pipe through a first water pipe, and the water pump is communicated with the spray head through a second water pipe. The water pump is electrically connected to a control switch fixedly installed at the bottom of the fixing plate and electrically connected to the detector body. Advantageous Effects

[0007] 1. For this steel structure weld detection device, the control switch can control the water pump to drive, and at the same time, the coupling agent inside the transparent liquid storage cylinder is conveyed to the inside of the second water pipe through the first water pipe and the connecting pipe, and then the coupling agent is sprayed onto the welded part of the steel structure through the spray head. After the coupling agent is sprayed, the ultrasonic probe can be used to detect the welded part. With this structure, spraying can be done at any time during the inspection, and the operation is relatively convenient.

[0008] 2. For the steel structure weld seam detection device, the coupling agent can be replenished into the interior of the transparent liquid storage cylinder by removing the sealing cover, and when the water pump is started, the outside air can enter the interior of the transparent liquid storage cylinder through the breathable membrane, thereby ensuring the air pressure balance inside and outside the transparent liquid storage cylinder, so that the coupling agent inside the transparent liquid storage cylinder can be pumped into the interior of the nozzle for spraying.

[0014] The following further elaborates the present application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and do not limit the utility model. Additionally, it should be noted that for the sake of description, only the parts related to the utility model are shown in the drawings.

[0015] In the drawings of the embodiments of the present utility model: The different types of hatching lines in the figure are not marked according to the national standard, nor are the materials of the components required. It is to distinguish the cross-sectional views of the components in the figure.

[0016] Please refer to Figures 1-3, a steel structure weld seam detection device, including a detector body 1, a connector 3 electrically connected to the outside of the detector body 1 through a connecting wire 2, and an ultrasonic probe 4 inserted outside the bottom end of the connector 3. A fixing plate 5 is fixedly sleeved on the outside of the connector 3, and a spray head 6 located on one side of the ultrasonic probe 4 is fixedly sleeved inside the fixing plate 5. The inside of the top end of the spray head 6 is communicated with a liquid spraying mechanism 7 fixedly installed on the outside of the detector body 1. Clamping plates 8 are arranged on both sides of the detector body 1, and a transparent liquid storage cylinder 9 is clamped inside the clamping plates 8. The clamping plates 8 can limit and support the transparent liquid storage cylinder 9 while facilitating the disassembly and assembly of the transparent liquid storage cylinder 9. A liquid adding pipe 10 is arranged on the outside of the transparent liquid storage cylinder 9, and a sealing cover 11 is threadedly sleeved on the outside of the top end of the liquid adding pipe 10. By removing the sealing cover 11, the coupling agent can be added into the transparent liquid storage cylinder 9 through the liquid adding pipe 10.

[0017] Among them, annular bosses 12 are arranged on the outside of both ends of the transparent liquid storage cylinder 9. The transparent liquid storage cylinder 9 can be limited by the annular bosses 12, so that the transparent liquid storage cylinder 9 can be stably clamped inside the clamping plates 8.

[0018] Among them, a breathable film 13 is attached to the inside of the sealing cover 11. The breathable film 13 prevents dust from the outside from entering the inside of the transparent liquid storage cylinder 9, and the breathable film 13 can conduct air, so that the air pressure inside the transparent liquid storage cylinder 9 is the same as that of the outside world. Furthermore, under the drive of the water pump 71, the coupling agent inside the transparent liquid storage cylinder 9 can be pumped by using the air pressure difference.

[0019] Among them, the liquid spraying mechanism 7 includes a water pump 71 fixedly installed on the outside of the detector body 1 and a connecting pipe 72 communicated with the inside of one end face of the transparent liquid storage cylinder 9. The water pump 71 is communicated with the connecting pipe 72 through a first water pipe 73, and the water pump 71 is communicated with the spray head 6 through a second water pipe 74. The water pump 71 is electrically connected to a control switch 75 fixedly installed at the bottom of the fixing plate 5 and electrically connected to the detector body 1. By operating the control switch 75, the water pump 71 can be driven to convey the coupling agent inside the transparent liquid storage cylinder 9 into the inside of the second water pipe 74, and then the coupling agent can be sprayed onto the steel structure weld seam position through the spray head 6.

[0020] When the device is in use, pick up the ultrasonic probe 4 by hand and move it above the position of the steel structure welding seam. Press the control switch 75 with the thumb to control the start of the water pump 71. While the coupling agent inside the transparent liquid storage cylinder 9 is transported to the inside of the second water pipe 74 by the drive of the water pump 71, the coupling agent is sprayed onto the surface of the welding seam through the nozzle 6. After the coupling agent spraying is completed, turn off the water pump 71 through the control switch 75. At this time, move the ultrasonic probe 4 to the position of the welding seam, and fit the bottom of the ultrasonic probe 4 to the surface of the steel structure. Detect the welding seam through the ultrasonic probe 4. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
