Description

Technical Field

[0001] The present invention relates to the field of galvanized pipe detection, and particularly to a measuring device for the galvanized layer of steel pipes. Background Art

[0002] Galvanized steel pipes are welded steel pipes with a hot-dip galvanized or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields, pipes for oil heaters, condensers, and coal distillation wash oil exchangers in chemical coking equipment, as well as pipe piles for trestles and support frames for mine tunnels. Hot-dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mines, chemical industries, electric power, railway vehicles, the automotive industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, and prospecting machinery.

[0003] For the thickness of the galvanized layer of galvanized pipes, it is impossible to judge by the naked eye of workers and a galvanized thickness detector needs to be used for detection. Moreover, during the production process, the produced galvanized pipes also need to be sampled and inspected. Such sampling inspections are generally carried out by manually holding a galvanized thickness detector, and it is also necessary to carry out the inspection when production is not in progress, which is time-consuming, laborious, and inefficient.

Detailed implementation manners

[0025] As Figure 1-7 shown, a steel pipe galvanized layer measuring device includes adjacent conveying rack 1, collecting rack 2 and detection rack 3.

[0026] A pipe dialing component is installed on the conveying rack 1. The pipe dialing component includes a plurality of dial rods 9, a first cylinder 10, a connecting rod 11 and a central shaft 12. One end of the dial rod 9 is fixed on the central shaft 12. Both ends of the central shaft 12 are connected to the connecting rod 11 through bearings. The other end of the connecting rod 11 is fixed on the conveying rack 1. The rod body of one of the connecting rods 11 is hinged to the telescopic end of the first cylinder 10. The bottom of the first cylinder 10 is hinged to the conveying rack 1. During use, the produced galvanized pipes are sent to the conveying rack 1, and then driven by the first cylinder 10, one end of the dial rod 9 is lifted, and the dial rod 9 is used to guide the galvanized pipes placed on the conveying rack 1 to the collecting rack 2.

[0027] A counting sensor 4 is installed on the conveying rack 1, and the counting sensor 4 is used to sense the number of galvanized pipes sent to the conveying rack 1.

[0028] A first baffle 26 is provided on one side of the collecting rack 2 away from the conveying rack 1, and the first baffle 26 is used to prevent the galvanized pipes rolling from the conveying rack 1 from rolling off the collecting rack 2.

[0029] A rolling assembly is installed on the detection frame 3. The rolling assembly includes two rotating rollers 5. Both ends of the rotating roller 5 are installed on the detection frame 3 through bearing seats. The rotating roller 5 is driven by a first motor 6, and the rotation directions of the two rotating rollers 5 are opposite. A first sensor 7 is provided between the two rotating rollers 5. The first sensor 7 is fixed on the detection frame 3. The first motor 6 drives the two rotating rollers 5 to rotate, which can drive the galvanized pipe clamped between the two rotating rollers 5 to rotate. By the first sensor 7 sensing the position, the galvanized pipe can stop for detecting the zinc layer thickness every time it rotates a quarter of the circumference.

[0030] A handling assembly is provided between the conveying frame 1 and the detection frame 3. The handling assembly includes a handling frame 27 placed outside the conveying frame 1 and the detection frame 3. Two U-shaped plates 13 are installed on the top of the handling frame 27. A lead screw 14 is installed on the U-shaped plate 13 through a bearing. The lead screw 14 is driven by a second motor 15. A displacement block 16 is threadedly connected to the lead screw 14. The two displacement blocks 16 are connected by a linkage rod 17. A second sensor 21 is installed at the bottom of the middle position of the linkage rod 17. A clamping assembly is connected below the displacement block 16, and the two groups of clamping assemblies are arranged oppositely. The clamping assembly includes a second cylinder 28, a third cylinder 18 and a plug rod 19. The second cylinder 28 is fixed on the displacement block 16. The telescopic end of the second cylinder 28 is vertically downward and connected to a mounting plate 20. The third cylinder 18 is horizontally fixed on the mounting plate 20. The plug rod 19 is connected to the telescopic end of the third cylinder 18. When it is necessary to handle the galvanized pipe, the second motor 15 drives the two displacement blocks 16 to move on the lead screw 14 until the second sensor 21 senses the position of the galvanized pipe, then the second motor 15 stops. Then the third cylinder 18 drives the plug rod 19 to insert into the galvanized pipe. Then the second cylinder 28 rises, and at the same time the second motor 15 reverses, driving the galvanized pipe to move towards the detection frame 3. Then the galvanized pipe is placed between the two rotating rollers 5. Then each device resets, and the galvanized pipe placed between the two rotating rollers waits for detection, and other produced galvanized pipes do not affect collection.

[0031] A detector 8 is provided on one side of the detection rack 3 away from the conveying rack 1. The detector 8 is controlled by a control assembly. The control assembly includes a bottom plate 22 installed on the ground and a vertical rack 23 slidably connected to the bottom plate 22. A slide rail is installed on the bottom plate 22. A slider is fixed to the bottom of the vertical rack 23. The vertical rack 23 is slidably connected to the slide rail through the slider. The vertical rack 23 is driven by a fifth cylinder 29 installed on the bottom plate 22. A cross bar 24 is connected to one side of the vertical rack 23 close to the detection rack 3. The bottom of the other end of the cross bar 24 is connected to a fourth cylinder 25. The telescopic end of the fourth cylinder 25 is connected to the detector 8. When the galvanized pipe is placed between the two rollers 5 and the handling assembly is reset, the fifth cylinder 29 pushes the vertical rack 23 forward until the detector 8 is placed above the galvanized pipe. Then the first motor 6 works to drive the galvanized pipe to rotate through the two rollers 5 until the galvanized pipe stops rotating after rotating a quarter of the circumference. The fourth cylinder 25 drives the detector 8 to descend. After the detector 8 touches the galvanized pipe to detect data, the fourth cylinder 25 drives the detector 8 to reset. Then the first motor 6 drives the galvanized pipe to rotate again until the detector 8 finishes detecting all four orientations of the galvanized pipe. The fifth cylinder 29 drives the vertical rack 23 to reset. Then the handling assembly transports the detected galvanized pipe back onto the conveying rack 1 and then sends the galvanized pipe to the collection rack 2 through the lever assembly.
