Detailed Description of the Preferred Embodiment

[0024] Please refer to Figures 1-3 for a further description of the embodiments of the present utility model;

[0025] As Figure 1 shown, a steel pipe hardness detection device includes a U-shaped machine body 1 and a steel pipe positioning component 4 located inside the machine body 1. The steel pipe positioning component 4 is used for positioning and clamping the steel pipe to be measured. The steel pipe is sleeved and fixed on the steel pipe positioning component 4, and can support the inner wall during hardness detection, which is beneficial to making the detection result more accurate;

[0026] A cavity 12 is opened inside the middle section of the machine body 1, and a strip groove 11 communicating with the cavity 12 is opened on the inner wall of the middle section of the machine body 1. An electric guide rail 6 is fixed inside the cavity 12, and a hardness detection component 5 is installed on the electric guide rail 6. The detection end of the hardness detection component 5 passes through the strip groove 11 and extends outside the machine body 1, and the hardness detection component 5 faces the steel pipe positioning component 4 directly. When the electric guide rail 6 works, it drives the hardness detection component 5 to move horizontally along the strip groove 11, which is convenient for detecting the hardness of multiple points on the same straight line of the steel pipe and ensuring the accuracy of the detection result.

[0027] One end of the machine body 1 is installed with a motor 2 through a slot. The motor 2 is a reduction motor. The output end of the motor 2 extends out of the machine body 1 and is detachably connected to the steel pipe positioning component 4. The motor 2 and the steel pipe positioning component 4 can specifically adopt detachable connection methods such as bolt connection and snap connection, which is convenient for the installation and disassembly of the motor 2 and the steel pipe positioning component 4. It should be noted that according to steel pipes of different model sizes, different sizes of steel pipe positioning components 4 can be replaced to meet the hardness detection requirements of various model steel pipes. And the other end of the machine body 1 is provided with a screw hole 13 coaxially distributed with the steel pipe positioning component 4. The diameter of the screw hole 13 is much larger than the diameter of the steel pipe positioning component 4. In order to facilitate steel pipes of different model sizes (multiple diameters) to pass through the screw hole 13 and be sleeved on the steel pipe positioning component 4, a limiting component 3 is threadedly connected in the screw hole 13. The inner end of the limiting component 3 is sleeved on the steel pipe positioning component 4 and is rotatably connected thereto. The limiting component 3 is used for limiting the steel pipe positioning component 4. When the motor 2 works, it will drive the steel pipe positioning component 4 and the steel pipe to rotate slowly together, and the hardness detection component 5 can then detect the hardness of the outer wall of the steel pipe all around, thereby expanding the detection area of the steel pipe and being beneficial to making the steel pipe detection result more accurate.

[0028] As Figure 1 Or as shown in Figure 2, a dashboard 7 is installed on the machine body 1 through a slot. During detection, the hardness value of the steel pipe is recorded by observing the data on the dashboard 7.

[0029] A control panel 8 is installed on the machine body 1. The control panel 8 can also be replaced with a PLC controller, as long as it is a programmable controller. The control panel 8 is electrically connected to the electrical components in the hardness detection device, which is convenient for the staff to operate the device.

[0030] As Figure 2 And 3 As shown, the steel pipe positioning component 4 includes a positioning rod 41, a pipe clamp 42 and a mounting head 43. The pipe clamp 42 is clamped on the positioning rod 41, and the pipe clamp 42 is close to the limiting component 3. The mounting head 43 is welded to one end of the positioning rod 41 and is bolted to the output end of the motor 2. The positioning rod 41 is coaxially distributed with the screw hole 13. The diameter of the positioning rod 41 is much smaller than the diameter of the screw hole 13. The inner end of the limiting component 3 is sleeved on the other end of the positioning rod 41 and is rotatably connected thereto.

[0031] Among them, the limiting component 3 includes a threaded head 31, a limiting socket head 32 and a handle 33. The threaded head 31 is threadedly connected in the screw hole 13. The limiting socket head 32 is integrally formed at the inner end of the threaded head 31, and the limiting socket head 32 is sleeved on the positioning rod 41 and is rotatably connected thereto. The diameter of the limiting socket head 32 is not greater than the diameter of the threaded head 31. The handle 33 is fixed to the outer end of the threaded head 31.

[0032] In addition, the hardness detection component 5 includes a hydraulic cylinder 51 and a telescopic ball head 52. The hydraulic cylinder 51 is installed on the electric guide rail 6, and the output end of the hydraulic cylinder 51 passes through the strip-shaped groove 11 and is fixedly connected to the telescopic ball head 52.

[0033] Working principle: When the device is in use, hold the handle 33 and rotate it outwards, which can make the threaded head 31 screw out of the screw hole 13. Then, move the handle 33 outwards to remove the limit sleeve 32 from the screw hole 13. After that, select the steel pipe positioning component 4 that matches the steel pipe to be tested, fix the installation head 43 at the output end of the motor 2 with bolts, and then remove the pipe clamp 42 from the positioning rod 41. Then, the steel pipe to be tested can be passed through the screw hole 13 and sleeved outside the positioning rod 41, so that one end of the steel pipe is in contact with the installation head 43. At this time, the pipe clamp 42 can be clamped on the positioning rod 41 to position the other end of the steel pipe. Reinstall the limit component 3 in the threaded head 31, and the limit sleeve 32 will be sleeved on the positioning rod 41;

[0034] After that, click the control panel 8 to start the hydraulic cylinder 51 to drive the telescopic ball head 52 to perform hardness detection on the steel pipe. The hardness data measured by the telescopic ball head 52 is reflected by the instrument panel 7. The staff can record the data on the instrument panel 7. The hardness detection is based on the existing technology and will not be elaborated here;

[0035] When the detection of the first site is completed, click the control panel 8 to turn off the hydraulic cylinder 51, and start the motor 2 and / or the electric guide rail 6. The motor 2 can drive the steel pipe positioning component 4 and the steel pipe to rotate slowly together. During this process, the positioning rod 41 in the steel pipe positioning component 4 will rotate in the limit sleeve 32, and the hardness detection component 5 can perform hardness detection on the outer wall of the steel pipe around the circumference. When the electric guide rail 6 works, it can drive the hardness detection component 5 to move horizontally, and the hardness detection component 5 can perform hardness detection on multiple sites around the outer wall of the steel pipe, expanding the detection area of the steel pipe and facilitating more accurate steel pipe detection results;

[0036] After the steel pipe detection is completed, according to the above operations, first remove the limit component 3 from the threaded head 31, then open the pipe clamp 42, and move the steel pipe towards the screw hole 13. The steel pipe can be removed from the positioning rod 41 and the threaded head 31.
