Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel production and transportation, in particular to a steel pipe production and transportation device with a straightening mechanism. Background Technique

[0002] The stainless steel pipe is a hollow long round steel, which has excellent properties such as wear resistance, corrosion resistance, high temperature resistance, oxidation resistance, etc., and is widely used in multiple fields. During the production process and transportation, due to reasons such as collision and handling, the steel pipe may be bent, so it needs to be straightened to facilitate subsequent use.

[0003] The patent number CN 221559386 U discloses a steel pipe production and transportation device with a straightening mechanism. Through the detection component, after the steel pipe is straightened, the steel pipe continues to be transported and enters the connecting plate. Under the action of the spring, the movable block is pushed to move towards the steel pipe, so that the outer surface of the steel pipe is in contact with the outer surface of the ball. If the steel pipe is straightened qualified, the ball and the steel pipe will always maintain stable contact, and the movable rod will not move. If the steel pipe is not straightened qualified, that is, the steel pipe is still bent, it will push the ball outward when contacting the ball, so that the movable block moves into the receiving groove, driving the movable rod to protrude outward. By observing the movement of the movable rod, the straightening condition of the steel pipe can be known.

[0004] However, in use, it has the following defects:

[0005] Since the thickness of the steel pipe is different, and the position of the detection component is fixed, the detection accuracy is insufficient. When the steel pipe passes through the detection component, it may not contact the detection component due to a slight bend, resulting in the inability to detect whether it is straightened, affecting the detection efficiency. Content of the Utility Model

[0006] The purpose of the utility model is to provide a steel pipe production and transportation device with a straightening mechanism, which solves the problems that the position of the detection component in the background technique is fixed, the detection accuracy is insufficient, and the steel pipe may not contact the detection component due to a slight bend when passing through the detection component, resulting in the inability to detect whether it is straightened.

[0007] To achieve the above object, the utility model provides the following technical solution: A steel pipe production and conveying device with a straightening mechanism, including a bottom groove, a top groove, a vertical frame and a socket ring. Between the front and rear inner side walls of the top groove of the bottom groove, a number of straightening rollers are rotatably connected. Fixed blocks are fixedly connected to the right ends of both the top groove and the bottom groove. A first laser distance measuring probe is fixedly connected to the bottom of the fixed block on the right side of the top groove and the top of the fixed block on the right side of the bottom groove. On the front and rear surfaces on the right side of the bottom groove, vertical frames are fixedly connected. A socket ring is slidably connected to the surface of the vertical frame. A support block is fixedly connected to the right side wall of the socket ring. A second laser distance measuring probe is fixedly connected to the surface of the support block facing the straightening roller. Indicator blocks are fixedly connected to the front and rear surfaces of the top groove on one side of the vertical frame.

[0008] In this technical solution, when the steel pipe passes through the upper and lower first laser distance measuring probes, the distances from its surface to the two first laser distance measuring probes can be measured. The sizes of the top groove and the bottom groove are exactly the same, and the types of the upper and lower straightening rollers are also the same. Therefore, in the case of complete straightening, the distances between the upper and lower surfaces of the steel pipe and the upper and lower first laser distance measuring probes should be the same. According to the data transmitted back by the laser detection probes, the specific straightening situation of the steel pipe can be known, so as to continue straightening or transport it away, improving the straightening efficiency and the practicability of the device. The bottom of the scale line on the vertical frame and the axis center of the straightening roller inside the bottom groove are located on the same horizontal plane. Since the distance between the top groove and the bottom groove can be adjusted according to the size of the steel pipe, after the distance adjustment is completed, the distance between the upper and lower straightening rollers can be known according to the indicator block. Then, the socket ring is slid to the center of the upper and lower straightening rollers according to the scale. At this time, the second laser distance measuring probe can detect the distance of the steel pipe from the front and back sides, and cooperate with the first laser distance measuring probe to perform distance measurement simultaneously from four directions, further improving the detection accuracy and accurately knowing the straightening situation.

[0009] Preferably, limiting blocks are fixedly connected to both sides of the front and rear surfaces of the top groove, and limiting frames are fixedly connected to both sides of the front and rear surfaces of the bottom groove. The limiting blocks are located inside the limiting frames.

[0010] Preferably, an adjusting frame is fixedly connected to the center of the front surface of the bottom groove, a threaded block is fixedly connected to the center of the front surface of the top groove. A threaded rod is vertically rotatably connected inside the adjusting frame. The threaded rod vertically penetrates the surface of the threaded block and is threadedly connected to the threaded block. A second motor is fixedly connected to the top of the adjusting frame. The outer end of the transmission shaft of the second motor is fixedly connected to the top of the threaded rod.

[0011] Preferably, a conveying groove is fixedly connected to the right end of the bottom groove. A number of conveying rollers are rotatably connected inside the conveying groove. The conveying rollers and the straightening rollers inside the bottom groove are located on the same horizontal plane.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. Through the fixing block and the first laser ranging probe, the present utility model can perform straightening detection. When the steel pipe passes through the upper and lower first laser ranging probes, the distances from its surface to the two first laser ranging probes can be measured. The bottom groove and the top groove have exactly the same dimensions, and the upper and lower straightening rollers are also of the same model. Therefore, in the case of complete straightening, the distances between the upper and lower surfaces of the steel pipe and the upper and lower first laser ranging probes should be the same. According to the data transmitted back by the laser detection probe, the specific straightening situation of the steel pipe can be known, so as to continue straightening or transport it away, improving the straightening efficiency and the practicality of the device.

[0016] 2. Through the vertical frame, scale lines, indicating block and the second laser ranging probe, the present utility model can detect the lateral straightening situation. The bottom of the scale line on the vertical frame and the rotation axis center of the straightening roller inside the bottom groove are on the same horizontal plane. Since the distance between the top groove and the bottom groove can be adjusted according to the size of the steel pipe, after the distance adjustment is completed, the distance between the upper and lower straightening rollers can be known according to the indicating block. Then, the socket ring is slid to the center of the upper and lower straightening rollers according to the scale. At this time, the second laser ranging probe can detect the distance of the steel pipe from the front and back sides, and cooperate with the first laser ranging probe to perform ranging simultaneously from four directions, thereby further improving the detection accuracy and accurately knowing the straightening situation, and improving the practicality of the device.

Specific embodiments

[0021] In order to make the technical means, creative features, achieving purposes and functions of the present utility model easy to understand, the following will be further elaborated in combination with specific embodiments.

[0022] A steel pipe production and conveying device with a straightening mechanism, see Figures 1 to 2 , including a bottom groove 1, a top groove 2, a vertical frame 13 and a socket ring 16. Between the front and rear inner side walls of the top groove 2 of the bottom groove 1, a number of straightening rollers 3 are rotatably connected. Fixed blocks 9 are fixedly connected to the right ends of both the top groove 2 and the bottom groove 1. At the bottom of the fixed block 9 on the right side of the top groove 2 and at the top of the fixed block 9 on the right side of the bottom groove 1, first laser distance measuring probes 10 are fixedly connected. When the steel pipe passes through the upper and lower first laser distance measuring probes 10, the distance from its surface to the two first laser distance measuring probes 10 can be measured. According to the data transmitted back by the laser detection probe, the specific straightening situation of the steel pipe can be known, so as to continue straightening or transport it away, improving the straightening efficiency and the practicality of the device; On the front and rear surfaces on the right side of the bottom groove 1, vertical frames 13 are fixedly connected. A socket ring 16 is slidably connected to the surface of the vertical frame 13. A support block 17 is fixedly connected to the right side wall of the socket ring 16. A second laser distance measuring probe 18 is fixedly connected to the surface of the support block 17 facing the straightening roller 3. Indicating blocks 15 are fixedly connected to the front and rear surfaces of the top groove 2 on one side of the vertical frame 13. According to the indicating blocks 15, the distance between the upper and lower straightening rollers 3 can be known, and then the socket ring 16 can be slid to the center of the upper and lower straightening rollers 3 according to the scale. At this time, the second laser distance measuring probe 18 can detect the distance of the steel pipe from the front and rear sides, and cooperate with the first laser distance measuring probe 10 to carry out distance measurement simultaneously from four directions, thereby further improving the accuracy of detection.

[0023] Specifically, as Figure 1 shown, limit blocks 5 are fixedly connected to both sides of the front and rear surfaces of the top groove 2, and limit frames 4 are fixedly connected to both sides of the front and rear surfaces of the bottom groove 1. The limit blocks 5 are located inside the limit frames 4. During the lifting process of the top groove 2, the limit blocks 5 will slide inside the limit frames 4, thus maintaining the stability during the lifting process.

[0024] It should be noted that, among them, the straightening rollers 3 on both sides inside the bottom groove 1 are driven by a first motor 301 to drive the steel pipe to move. The first motor 301 is installed on the outer side wall of the bottom groove 1 and is provided with a corresponding control switch for conveniently turning on and off the first motor 301.

[0025] It is worth noting that, as Figure 1 shown, a regulating frame 6 is fixedly connected to the center of the front surface of the bottom groove 1, and a threaded block 8 is fixedly connected to the center of the front surface of the top groove 2. A threaded rod 7 is rotatably connected vertically inside the regulating frame 6. The threaded rod 7 vertically penetrates the surface of the threaded block 8 and is threadedly connected to the threaded block 8. The top end of the regulating frame 6 is fixedly connected to a second motor 701. The outer end of the transmission shaft of the second motor 701 is fixedly connected to the top end of the threaded rod 7. After the second motor 701 is started, it will drive the threaded rod 7 to rotate. During the rotation of the threaded rod 7, the threaded block 8 will move up and down inside the regulating frame 6, thereby driving the top groove 2 to lift and lower together to complete the spacing adjustment and adapt to the sizes of different steel pipes.

[0026] It is worth noting that, as Figure 1 and Figure 2 shown, a conveying groove 11 is fixedly connected to the right end of the bottom groove 1. A number of conveying rollers 12 are rotatably connected inside the conveying groove 11. The conveying rollers 12 and the straightening rollers 3 inside the bottom groove 1 are located on the same horizontal plane. Therefore, after the steel pipe is straightened, it can just move onto the conveying rollers 12 and slide away. Since there is no height difference, it is possible to avoid the impact caused by the sudden drop of the steel pipe after straightening and discharging, which affects the integrity of the steel pipe.

[0027] It is worth noting that, as Figure 1 shown, the bottom groove 1 and the top groove 2 have the same size, and the first laser ranging probes 10 at the right ends of the top groove 2 and the bottom groove 1 are located on the same vertical line, so that the steel pipe can be ranged exactly from the upper and lower sides, ensuring the accuracy of ranging.

[0028] It is worth noting that, as Figure 1 shown, the indicating block 15 and the center of the rotating shaft of the straightening roller 3 are located on the same horizontal plane. Scale lines 14 are provided on the surface of the vertical frame 13. The scale lines 14 facilitate the position adjustment of the socket ring 16, so that the socket ring 16 is exactly located in the center of the top groove 2 and the bottom groove 1, enabling the second ranging probe to range the steel pipe horizontally. At the same time, an extrusion bolt is threadedly connected to the side wall of the socket ring 16. After sliding to a certain position, the bolt can be tightened to squeeze the socket ring 16 to keep it stationary.

[0029] It should be noted that the data measured by the laser ranging probe will be transmitted back to the computer to obtain the specific data. Since the existing technology is relatively mature, it will not be elaborated here.

[0030] In actual use, the stainless steel pipe is inserted from the left end between the top groove 2 and the bottom groove 1. During the movement of the steel pipe, it undergoes straightening treatment by the upper and lower straightening rollers 3. The straightened steel pipe leaves from the conveying groove 11 on the right side. During this process, through the fixed block 9 and the first laser distance measuring probe 10, straightening detection can be carried out. When the steel pipe passes through the upper and lower first laser distance measuring probes 10, the distance from its surface to the two first laser distance measuring probes 10 can be measured. The sizes of the top groove 2 and the bottom groove 1 are exactly the same, and the upper and lower straightening rollers 3 are also of the same model. Therefore, in the case of complete straightening, the distances between the upper and lower surfaces of the steel pipe and the upper and lower two first laser distance measuring probes 10 should be the same. According to the data transmitted back by the laser detection probe, the specific straightening situation of the steel pipe can be known, so as to continue straightening or transport it away, improving the efficiency of straightening and the practicability of the device. At the same time, through the vertical frame 13, the scale line 14, the indicating block 15 and the second laser distance measuring probe 18, the lateral straightening situation can be detected. The bottom of the scale line 14 on the vertical frame 13 is at the same horizontal plane as the rotation axis center of the straightening roller 3 inside the bottom groove 1. Since the top groove 2 and the bottom groove 1 can adjust the spacing according to the size of the steel pipe, after the spacing adjustment is completed, the spacing between the upper and lower straightening rollers 3 can be known according to the indicating block 15. Then, according to the scale, the socket ring 16 is slid to the center of the upper and lower straightening rollers 3. At this time, the second laser distance measuring probe 18 can detect the spacing of the steel pipe from the front and back sides, and cooperate with the first laser distance measuring probe 10 to carry out distance measurement in four directions at the same time, further improving the accuracy of detection and accurately knowing the straightening situation, and improving the practicability of the device.
