Description

Technical Field

[0001] The present invention relates to the field of industrial pipelines, and more specifically, to an industrial pipeline weld detection device. Background Art

[0002] When industrial pipelines are processed, welding equipment is needed to weld them together. After welding, a weld detection device is needed to detect the welds of the pipelines. The welds are soaked in mineral oil and then magnesium powder is sprinkled in the welds. The defects of the welds are detected by the luminescence of the magnesium powder. However, when the welds of the pipelines are soaked in mineral oil, a lot of welding slag remains in the welds of the pipelines. The welding slag easily falls into the mineral oil, resulting in a decrease in the permeability of the mineral oil and making it difficult to stay in the defects of the welds. At the same time, in the process of sprinkling magnesium powder, the weld surface of the pipeline is in an arc shape, which reduces the adsorption of magnesium powder, making it difficult for the magnesium powder to stay in the defects of the welds, thereby reducing the observation effect of the defects of the pipeline welds.

The detection mechanism 2 comprises an outer frame 21, an oil injection mechanism 22, a powder sprinkling mechanism 23, and a shielding mechanism 24. The oil injection mechanism 22 is installed at the lower end of the outer frame 21, and the pulley 3 is installed on the inner side of the outer frame 21, the powder sprinkling mechanism 23 is installed on the top of the outer frame 21, and the shielding mechanism 24 is installed on the inner side of the outer frame 21. A total of six pulleys 3 are provided, and the six pulleys 3 are simultaneously connected by a transmission belt to transmit, so that the industrial pipeline X rotates inside the outer frame 21.

[0024] Among them, the oil injection mechanism 22 includes a shell 221, an oil filling port 222, an oil storage tank 223, a compression rod 224, and a contact mechanism 225. The shell 221 is embedded and installed at the bottom of the outer frame 21, and the oil filling port 222 runs through the lower end of the shell 221. The upper end of the oil filling port 222 is connected with the middle of the lower end of the oil storage tank 223. A compression rod 224 runs through the inside of the oil storage tank 223. The upper end of the oil storage tank 223 is connected with the lower end of the contact mechanism 225. The contact mechanism 225 is embedded and installed at the upper end of the shell 221. There are two compression rods 224, which are symmetrically installed at the two ends of the outer side of the oil storage tank 223, which is beneficial to squeeze the mineral oil inside the oil storage tank 223 at the same time, so that the mineral oil inside the oil storage tank 223 is sprayed upward.

[0025] Among them, the contact mechanism 225 includes a telescopic hose 25a, a nozzle 25b, a ball 25c, and a tray 25d. The lower end of the telescopic hose 25a is connected to the upper end of the oil storage tank 223, and the upper end of the telescopic hose 25a is provided with a nozzle 25b, and the upper end of the nozzle 25b is installed with a ball 25c.

[0026] The specific usage and function of this embodiment are as follows:

[0027] In the present invention, the industrial pipeline X is extended into the outer frame 21. At this time, the outer wall of the industrial pipeline X is in contact with the pulley 3, and the motor 1 is started to drive the pulley 3 to rotate. At this time, the industrial pipeline X rotates inside the outer frame 21. During the rotation, the compression rod 224 is pressed, and the external mineral oil connected through the oil filling port 222 enters the oil storage tank 223, and then sprays from the inside of the oil storage tank 223 to the inside of the telescopic hose 25a.

During the rotation of the industrial pipeline X, the ball 25c assists the rotation to ensure that the industrial pipeline X can rotate on the nozzle 25b. At the same time, the welding slag remaining in the weld of the industrial pipeline X falls down to the inside of the tray 25d for collection, so as to prevent the welding slag from falling into the oil storage tank 223 and contacting with the mineral oil, thereby ensuring the permeability of the mineral oil inside the oil storage tank 223 in the weld of the industrial pipeline X.

[0028] Embodiment 2:

[0029] As attached Figure 5 To Attachment Figure 7As shown:

[0030] Among them, the powder spreading mechanism 23 includes a rotating rod 231, a hopper 232, a powder storage box 233, a grinding disc 234, and a powder spraying mechanism 235. The rotating rod 231 runs through the inside of the hopper 232, and the hopper 232 is embedded in the middle of the upper end of the powder storage box 233. A grinding disc 234 is welded to the lower end of the rotating rod 231, and the grinding disc 234 is located inside the powder storage box 233. A powder spraying mechanism 235 is embedded at the lower end of the powder storage box 233. The grinding disc 234 is an inverted V-shaped structure, which is conducive to guiding the magnesium powder downward. At the same time, through the rotation of the grinding disc 234, the magnesium powder is discharged to the powder spraying mechanism 235. There are three powder spraying mechanisms 235, which are equidistantly distributed at the lower end of the powder storage box 233 to increase the area of ​​magnesium powder discharge, thereby ensuring that the magnesium powder is evenly and comprehensively sprinkled on the weld of the industrial pipeline X.

[0031] Among them, the powder spraying mechanism 235 includes a nozzle 35a, a fixed block 35b, a torsion shaft 35c, and an opening and closing piece 35d. The nozzle 35a is embedded in the lower end of the powder storage box 233, and a fixed block 35b is fixedly installed on the inner wall of the nozzle 35a. The fixed block 35b is hinged to the middle part of the outer end of the opening and closing piece 35d through the torsion shaft 35c. The opening and closing piece 35d is located inside the nozzle 35a. There are two fixed blocks 35b, torsion shaft 35c and opening and closing piece 35d, and they are symmetrically installed inside the nozzle 35a, which is conducive to guiding the magnesium powder downward for discharge and avoiding friction adsorption of the magnesium powder and clogging inside the nozzle 35a.

[0032] Among them, the shielding mechanism 24 includes a spring 241, a shielding plate 242, and a guide piece 243.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In the present invention, magnesium powder can be added through the hopper 232. After the magnesium powder is added to the powder storage box 233, the grinding disc 234 is driven to rotate inside the powder storage box 233 by the rotation of the rotating rod 231, which is conducive to guiding the magnesium powder downward. At the same time, the rotation of the grinding disc 234 accelerates the discharge of the magnesium powder into the nozzle 35a. The three nozzles 35a increase the area of ​​magnesium powder discharge, thereby ensuring that the magnesium powder is evenly and comprehensively sprinkled on the weld of the industrial pipeline X. The weight of the magnesium powder entering the nozzle 35a increases, so that the opening and closing piece 35d is around The torsion shaft 35c rotates downward to guide the magnesium powder downward for discharge, so as to prevent the magnesium powder from being adsorbed by friction and blocked inside the nozzle 35a. The magnesium powder moves downward along the guide plate 243 and is adsorbed in the weld of the industrial pipeline X. At the same time, the spring 241 applies elastic force to the shielding plate 242, so that the shielding plate 242 contacts the outer surface of the industrial pipeline X, shields the weld of the industrial pipeline X, and increases the darkness of the weld of the industrial pipeline X, thereby ensuring the luminous display of the magnesium powder at the weld of the industrial pipeline X and improving the observation effect of defects.
