[0001] The present application relates to the technical field of workpiece detection, and in particular to an automatic strength detection and sorting device for steel pipes used in construction. Background Art

[0002] Steel pipes are commonly used construction workpieces in various industries. For example, in the construction industry, steel pipes are often used in structural support frames, pipeline systems, cable protection, guardrails and other safety facilities, etc. In order to ensure the construction quality of steel pipes, strength tests are required during the manufacture of steel pipes and before they are officially used to ensure the reliability of the steel pipes.

[0003] In the prior art, the strength test of steel pipes includes many aspects: such as tensile strength, compressive strength, shear strength, fatigue strength, crack and impurity detection, etc. Most of the strength tests are only related to the material of the steel pipe, so only a few of the batches of steel pipes need to be tested by random sampling. However, for the cracks and impurities of the steel pipes, which are the test items that indirectly affect the strength of the steel pipes, since the cracks and impurities of each steel pipe are different, each steel pipe needs to be tested separately. Usually, this kind of test is carried out by workers holding various flaw detection instruments to test one by one, and manually sort out qualified and unqualified products. This testing method is labor-intensive and inefficient, and there may be errors in the test results due to differences in workers' skills.

[0004] Therefore, it is necessary for the inventor to design a new automatic strength detection and sorting device for steel pipes for construction to overcome the above problems. Summary of the invention

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] like Figures 1 to 5 As shown, an automatic strength detection and sorting device for steel pipes 15 for construction includes a charging box 1 and a flaw detection device 2; wherein: a charging port 3 is fixedly arranged on the front side of the charging box 1; a support plate 4 is slidably arranged on the rear side plate of the charging box 1, and a bracket 5 and a pushing mechanism are fixedly arranged on the support plate 4, the bracket 5 is adapted to a single steel pipe 15, and the pushing mechanism is used to push the steel pipe 15 on the bracket 5 to the front or rear side; a storage layer 6 is fixedly arranged on the upper end of the charging box 1, and the storage layer 6 is used to store the steel pipe 15 pushed forward by the pushing mechanism; the flaw detection device 2 is fixedly arranged above the bracket 5 and is electrically connected to the pushing mechanism, and the flaw detection device 2 is used to detect the steel pipe 15 on the bracket 5.

[0035] Specifically, the steel pipes 15 to be inspected are put into the loading box 1 in batches. When the support plate 4 slides from bottom to top, one steel pipe 15 is transported upward each time. The steel pipe 15 is inspected by the flaw detection device 2 on the bracket 5 to detect its cracks, that is, the impurities contained. If there are too many cracks or the impurity particles are too large, the strength quality of the steel pipe 15 does not meet the requirements. At this time, the flaw detection device 2 controls the push mechanism electrically connected to it to push the steel pipe 15 forward or backward. If it is pushed forward, the unqualified steel pipe 15 will fall into the storage layer 6 for storage; if the strength quality of the steel pipe 15 meets the requirements, the steel pipe 15 will be pushed in the other direction, so that the automatic inspection and sorting of the steel pipe 15 is realized. After the inspection of a steel pipe 15 is completed, during the downward sliding of the support plate 4, a steel pipe 15 in the loading box 1 will fall on the bracket 5 and move upward with the support plate 4, so as to realize the sequential inspection of multiple steel pipes 15. In this embodiment, the support plate 4 is arranged to slide up and down, and the individual steel pipes 15 are driven to move to the flaw detection device 2 for detection in turn, which greatly reduces the labor intensity of the workers and improves the detection efficiency. At the same time, by setting a pushing mechanism and electrically connecting it to the flaw detection device 2, the qualified and unqualified steel pipes 15 are pushed in different directions, thereby realizing automatic sorting of the steel pipes 15, which also reduces the labor cost and ensures the reliability of detection.

[0036] It should be noted that the width of the charging box 1 should be slightly larger than the length of the steel pipe 15 , but should not be too long, as long as it is ensured that only one steel pipe 15 falls on the bracket 5 at a time.

[0037] The push mechanism includes two groups of push rods 7, and the two groups of push rods 7 are symmetrically arranged on both sides of the axis of the bracket 5. Each group of push rods 7 includes two push rods, and the two push plates are respectively arranged at the left and right ends of the support plate 4. Specifically, the two groups of push rods 7 are arranged on both sides of the axis of the bracket 5, which can achieve the effect of pushing the steel pipe 15 in two directions when the push rods 7 are extended. Each group of push rods 7 is provided with two push rods, and the two ends of the steel pipe 15 are pushed at the same time, which can ensure that the steel pipe 15 is balanced when being pushed, and avoid the situation where the steel pipe 15 cannot be pushed out of the bracket 5. The push rod 7 here is built into the support plate 4, and the top of its telescopic end in the contracted state does not contact the steel pipe 15 on the bracket 5. The push rod 7 can be selected from any device that can achieve telescopicity, such as a micro cylinder, a motor screw, etc. In order to install the push rod 7 normally, the thickness of the support plate 4 can be appropriately increased. Preferably, a wiring harness port for routing the push rod 7 can also be set on the support plate 4.

[0038] It also includes a first cylinder 8, which is fixedly arranged below the charging box 1, and the output end of the first cylinder 8 is fixedly connected to the support plate 4. Specifically, the support plate 4 is driven to slide up and down by the first cylinder 8. The first cylinder 8 is fixed below the charging box 1 by an external fixing member, and any fixing method that can make the telescopic end of the first cylinder 8 drive the support plate 4 to slide up and down can be used here, and the number of the first cylinders 8 is preferably more than two.

[0039] The rear side plate of the charging box 1 is tilted outward, and a guide plate 9 is fixedly arranged inside the charging box 1. A loading port 10 adapted to the support plate 4 is fixedly arranged at the bottom of the rear end of the charging box 1. Specifically, the tilted setting of the rear side plate makes it difficult for the steel pipe 15 on the bracket 5 to fall off the support plate 4 due to the squeezing of other steel pipes 15 in the charging box 1 when the steel pipe 15 moves upward. The guide plate 9 makes the steel pipe 15 slide toward the upper loading port 10 under the action of gravity until it falls on the bracket 5. It should be noted that the sliding formation of the support plate 4 should prevent the bracket 5 from detaching from the loading port 10 to prevent the steel pipe 15 in the charging box 1 from falling. At the same time, the telescopic end of the first cylinder 8 can also achieve the function of filling the loading port 10 and preventing the steel pipe 15 from falling when the support plate 4 is pushed up.

[0040] The flaw detection device 2 includes an ultrasonic flaw detector body 201 and a probe 202 that are connected in a matching manner. The probe 202 is slidably arranged along the axial direction of the steel pipe 15. Specifically, there are various devices for flaw detection of the steel pipe 15. In addition to ultrasonic detection, there are also eddy current detection, X-ray detection, etc. In comparison, the instrument cost of ultrasonic detection is low and the effect is good. When in use, since the effective range of ultrasonic detection is constant and the length of the steel pipe 15 is long, the probe 202 should be slid within a certain range so that all positions on the steel pipe 15 can be detected.

[0041] The ultrasonic flaw detector body 201 is fixedly mounted on the mounting frame 11, a slide rail 12 is fixedly mounted on the mounting frame 11, a slider 13 is slidably mounted on the slide rail 12, and the probe 202 is fixedly mounted on the slider 13. Specifically, the probe 202 slides on the slide rail 12 as the slider 13 slides to realize the overall detection of the steel pipe 15. It should be noted that when the ultrasonic probe 202 is inspecting the steel pipe 15, the probe 202 needs to be in close contact with the steel pipe 15, and a coupling agent needs to be applied between the two to ensure the sound wave propagation effect. Therefore, a coating device can be set in front of the moving direction of the probe 202, and the coupling agent can be applied to the surface of the steel pipe 15 in advance when the probe 202 moves. In addition, since the push mechanism cannot work when the probe 202 contacts the steel pipe 15, the probe 202 can be set to a lifting type. After the inspection is completed, the probe 202 moves up so that the push mechanism can work normally, or the first cylinder 8 is set to two sets of working positions, the higher working position is used for contact inspection with the probe 202, and the lower position is used for the push mechanism to push the steel pipe 15. In addition, the movement of the slider 13 can be done by cylinder push, or it can be moved in the form of an electric drive slider 13, which is not the core innovation of this case.

[0042] It also includes a good product box 14, which is fixedly arranged on the back of the charging box 1 and is used to contain the steel pipes 15 pushed backward by the pushing mechanism. Specifically, since the number of unqualified steel pipes 15 is relatively small, the unqualified products can be pushed forward to the storage layer 6 with a smaller space, and the qualified products can be pushed backward to the good product box 14 for storage.

[0043] The material of the bracket 5 is rubber. Specifically, when using an ultrasonic flaw detector, the bracket 5 should not be made of metal materials that are easy to resonate with the steel pipe 15. The rubber material can reduce the resonance and make the detection result more accurate.

[0044] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
