[0002] Steel pipes are hollow, long, round steel materials widely used in industrial pipelines for petroleum, chemical, medical, and food processing, as well as in mechanical structural components. After cutting, the cut edges of steel pipes need to be ground to remove excessive metal burrs that could affect their use. Currently, grinding equipment is mostly used to grind the pipe cut edges.

[0003] In existing technology, motors are installed on both sides of a steel pipe to drive rotating shafts. Grinding stones are installed at the output ends of the shafts, and the steel pipe is supported by a bracket.

[0034] refer to Figures 1 to 6 As shown, this utility model discloses a steel pipe end grinding device 10, including a grinding disc mechanism 11, a steel pipe frame 12, and a feeding device 13. The grinding disc mechanism 11 includes a motor and a grinding disc mounted on the motor output end. The motor drives the grinding disc to rotate, and the surface of the grinding disc contacts the end of the steel pipe 1131 being processed. As the grinding disc rotates, friction is generated between the grinding disc and the end of the steel pipe 1131, cleaning burrs and other impurities from the steel pipe 1131. The grinding disc mechanism 11 corresponds to both ends of the steel pipe 1131 being processed, effectively cleaning burrs and other impurities from both ends. The grinding disc mechanism 11 includes a base 111, a support 112, and a rotating grinding disc 113. Figure 1As shown, the base 111 is shaped like a triangular stool, with stool legs positioned at both ends and the middle. A support 112 is located on the upper end of the base 111 to support the processed steel pipe 1131. The supports 112 are distributed along a straight line along the length of the base 111, ensuring that the support centers of the supports 112 are all on the same straight line. After the processed steel pipe 1131 is placed on the supports 112, its outer surface can simultaneously contact multiple supports 112, increasing the stability of the support for the processed steel pipe 1131. The supports 112 at both ends of the base 111 correspond to rotating grinding discs 113, so that the two ends of the processed steel pipe 1131 correspond to the side ends of the rotating grinding discs 113 at both ends. The rotation center of the rotating grinding discs 113 is higher than the rotation center of the processed steel pipe 1131 on the supports 112 to prevent the processed steel pipe 1131 from detaching from the supports 112 due to inertia. A steel pipe frame 12 is arranged side-by-side with a base 111 on one side of the base 111 to hold the steel pipes 121 to be processed. The steel pipe frame 12 includes two support beams 123, which are arranged parallel to each other and extend perpendicular to the steel pipes 1131 to be processed. Multiple steel pipes 121 to be processed are placed side-by-side on the support beams 123. The support beams 123 are inclined downwards towards the support 112, causing the steel pipes 1131 to move along the support beams 123 towards the support 112 under gravity. The steel pipes 121 to be processed are parallel to the steel pipes 1131 to be processed and are higher than the steel pipes 1131 to be processed. A loading device 13 is installed on the base 111. The loading device 13 includes a foot pedal 131, a linkage mechanism 132, and a lifting plate 133 connected sequentially from bottom to top. Foot pedal 131 extends to one side of the steel pipe frame 12 via linkage mechanism 132, facilitating stepping on it from one side of the steel pipe frame 12. Foot pedal 131 is positioned along its length at both ends of the rotating rod 1321 and is located outside the steel pipe to be processed 121, allowing it to be stepped on from either side of the steel pipe frame 12. Stepping on foot pedal 131 controls the lifting plate 133 to move up and down for loading via linkage mechanism 132. The extended end of foot pedal 131 is inclined upwards, and its lower end is fixedly connected to the rotating rod 1321. Stepping down on the extended end of foot pedal 131 causes the rotating rod 1321 to rotate within the positioning ring 1112. The first connecting rod 1322 is fixedly connected to the rotating rod 1321 and positioned on the side opposite to foot pedal 131. The first connecting rod 1322 rotates upwards with the rotating rod 1321, pushing the second connecting rod 1323 upwards and causing the lifting plate 133 to move upwards. The lifting plate 133 moves upward to lift the steel pipe 121 to be processed and the steel pipe 1131 to be processed at the same time. After being lifted, the steel pipe 1131 moves downward along the second guide plate structure 1332 and gets off the support 112. After being lifted, the steel pipe 121 to be processed moves downward along the first guide plate structure 1331 and gets off the steel pipe frame 12. It moves to the stop by the baffle 1333 and then stops.After the pedal is released, the lifting plate 133 moves downward under the influence of gravity. During this downward movement, the two ends of the steel pipe 121 to be processed are intercepted by the outer shells of the corresponding rotating grinding discs 113. The grinding disc shells 1132 of the rotating grinding discs 113 are arc-shaped and tilt downward along the direction from the steel pipe frame 12 to the support 112. The steel pipe to be processed is guided by the grinding disc shells 1132 and falls to the support center of the support 112. The lifting plate 133 includes a first guide plate structure 1331 and a second guide plate structure 1332. The first guide plate structure 1331 tilts downward along the direction from the lower end of the adjacent steel pipe 121 to the center of the support 112. The second guide plate structure 1332 is parallel to the first guide plate structure 1331 and tilts downward from the lower end of the steel pipe 1131 being processed.

[0035] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the rotating grinding disc 113 includes an arc-shaped grinding disc shell 1132, which covers the turntable 1133 of the rotating grinding disc 113 and is inclined downward in the front-back direction. When the foot pedal 131 is pressed, the lifting plate 133 moves upward, causing the steel pipe 121 to be processed to move upward. At this time, the height of the steel pipe 121 is higher than the height of the grinding disc shell 1132, that is, the steel pipe 121 is located above the grinding disc shell 1132. As the steel pipe 121 moves downward along the first guide plate structure 1331, both ends of the steel pipe 121 gradually contact the outer wall of the grinding disc shell 1132. At this time, the steel pipe 121 is at both ends... The steel pipe 121 is detached from the first guide plate structure 1331 under the support of the grinding disc shell 1132. Then, since the grinding disc shell 1132 is arc-shaped and tilts downward in the front-back direction, the steel pipe 121 to be processed moves downward along the outer wall of the grinding disc shell 1132 under the guidance of the arc contour of the outer wall of the grinding disc shell 1132. The rear end of the grinding disc shell 1132 is connected to the support center of the bracket 112. The steel pipe 121 to be processed moves downward to the support center of the falling bracket 112 so that it can be ground by the turntable 1133.

[0036] Combination Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, in some embodiments, the first guide plate structure 1331 further includes a baffle 1333. The baffle 1333 is located at the junction of the first guide plate structure 1331 and the bracket 112 and extends vertically upward to stop the steel pipe 121 to be processed, so that the steel pipe 121 to be processed stops at the baffle 1333 during the upward movement of the first guide plate structure 1331. After the foot pedal 131 is pressed, the first guide plate structure 1331 first moves upward to the upper position. At this time, the height of the steel pipe 121 to be processed is higher than the height of the grinding disc shell 1132. At this time, the steel pipe 121 to be processed is not in contact with the outer wall of the grinding disc shell 1132, and therefore cannot move along the outer wall of the grinding disc shell 1132. At this time, the baffle 1333 stops the steel pipe 121 to be processed, so that the steel pipe 121 to be processed stops moving downward, thereby preventing the steel pipe 121 to be processed from not falling accurately into the bracket 112. During the downward movement of the first guide plate structure 1331, when both ends of the steel pipe 121 to be processed are in contact with the outer wall of the grinding disc shell 1132, as the first guide plate structure 1331 continues to move downward, the baffle 1333 gradually moves below the grinding disc shell 1132, and the steel pipe 121 to be processed gradually detaches from the first guide plate structure 1331 and moves downward with the outer wall of the grinding disc shell 1132. Under the guidance of the grinding disc shell 1132, it can accurately fall into the support center of the bracket 112, improving the accuracy of feeding.

[0037] Combination Figure 1 , Figure 2 , Figure 3 As shown, in some embodiments, there are multiple supports 112, which are arranged sequentially and at intervals along the length of the processed steel pipe 1131. For example, there are three supports 112, which support both ends and the middle position of the processed steel pipe 1131 respectively. Each support 112 includes a first support arm 1121 and a second support arm 1122. The lower ends of the first support arm 1121 and the second support arm 1122 are joined together to form a support center, and the upper ends are symmetrically separated in the front-back direction to form a guide slope 1123 that guides the support center from top to bottom. Under the combined action of the rotational friction of the turntable 1133 and the supporting force of the support 112, the processed steel pipe 1131 can be stably positioned in the support 112 without detaching from the support 112, while ensuring the grinding quality of the processed steel pipe 1131.

[0038] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the rotating grinding disc 113 is in the shape of a disc and is located on one side of the processed steel pipe 1131. The side of the rotating grinding disc 113 contacts the pipe head of the processed steel pipe 1131, and the rotating grinding disc 113 rotates from top to bottom toward the direction close to the processed steel pipe 1131.

[0039] For example, in combination Figure 1 and Figure 4 As shown, the processed steel pipe 1131 is located behind the rotating grinding disc 113. The outer rear wall of the turntable 1133 contacts the end of the processed steel pipe 1131. The rotation center of the turntable 1133 is higher than the rotation center of the processed steel pipe 1131 on the support 112. The turntable 1133 is arranged according to... Figure 4 Rotating in the direction indicated by arrow E, since the center of turntable 1133 is higher than the center of the processed steel pipe 1131, the direction of the extrusion force exerted by turntable 1133 on the processed steel pipe 1131 is downward along the line connecting the two centers. The frictional force is perpendicular to the extrusion force and downward, so the processed steel pipe 1131 is subjected to a reasonable downward component of force, ensuring that the processed steel pipe 1131 remains at the center of support 112 and does not move upward, thus guaranteeing the frictional stability of the processed steel pipe 1131.

[0040] Combination Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the first guide plate structure 1331 and the second guide plate structure 1332 are arranged in parallel. Both the first guide plate structure 1331 and the second guide plate structure 1332 are inclined downwards in the front-to-back direction. When the lifting plate 133 is at its lowest position, the upper end of the first guide plate structure 1331 contacts the lower end of the steel pipe 121 to be processed, and the upper end of the second guide plate structure 1332 contacts the lower end of the steel pipe 1131 to be processed. This allows the steel pipe 121 to be processed and the steel pipe 1131 to be processed to be lifted simultaneously during the upward movement of the lifting plate 133. Because the first guide plate structure 1331 and the second guide plate structure 1332 are arranged in parallel, the downward movement speeds of the steel pipe 121 to be processed and the steel pipe 1131 to be processed are similar, enabling synchronous loading and unloading to reduce the occurrence of accumulation problems.

[0041] Combination Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the linkage mechanism 132 includes a rotating rod 1321, a first connecting rod 1322, a second connecting rod 1323, and a guide rail 1324. The rotating rod 1321 is located at the lower part of the base 111. Along its length, both ends of the rotating rod 1321 extend to both sides of the steel pipe frame 12. Foot pedals 131 are provided on both sides of the steel pipe frame 12 for convenient operation. The foot pedals 131 extend vertically from the side wall of the rotating rod 1321 toward one side of the steel pipe frame 12, so that the operation of stepping on the foot pedals 131 on one side of the steel pipe frame 12 can prevent the processed steel pipe 1131 from falling and injuring people. The first connecting rod 1322 extends vertically from the side wall of the rotating rod 1321 and toward the side away from the steel pipe frame 12. During the pressing of the foot pedal 131, since the first connecting rod 1322 and the foot pedal 131 are positioned opposite each other, they rotate in opposite directions. Pressing the foot pedal 131 downwards causes the first connecting rod 1322 to rotate upwards, thereby pushing the second connecting rod 1323 upwards. The second connecting rod 1323 is hinged to the extended end of the first connecting rod 1322 and extends upwards to be fixedly connected to the lifting plate 133. A guide rail 1324 is provided on the bracket 112. The guide rail 1324 is a guide plate with a through guide hole 1325. The second connecting rod 1323 passes upwards through the guide hole 1325 and is fixedly connected to the lifting plate 133. The guide rail 1324 is a thin plate to ensure that the length of the guide hole 1325 in the downhill direction is not too long, which could cause the second connecting rod 1323 to jam. In some embodiments, the length of the guide rail 1324 is 5mm to 10mm.

[0042] Combination Figure 1 , Figure 2 As shown, in some embodiments, the base 111 further includes a positioning platform 1111. The positioning platform 1111 is located below the rotating rod 1321 and extends through the base 111 along its length. A positioning ring 1112 protrudes from the top surface of the positioning platform 1111, and the rotating rod 1321 passes through the positioning ring 1112. There are multiple positioning rings 1112, and their centers are located on the same straight line. The rotating rod 1321 passes through each positioning ring 1112 in sequence. The rotating rod 1321 can rotate relative to the positioning ring 1112, while the positioning ring 1112 restricts the rotating rod 1321 from moving to ensure the consistency of the movement trajectory of each lifting plate 133.

[0043] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, there are multiple feeding devices 13, which are distributed along the length of the processed steel pipe 1131. These multiple feeding devices work together to simultaneously lift the steel pipe 121 to be processed by multiple lifting plates 133, ensuring that the steel pipe 121 remains stable and does not sway or tilt. Furthermore, the rotating rods 1321 of the multiple feeding devices 13 are integrated. Stepping down on the pedal controls the rotation of the rotating rod 1321. The rotation of one rotating rod 1321, under the constraint of multiple positioning rings 1112, simultaneously controls the upward movement of multiple lifting plates 133, ensuring consistent movement of the lifting plates 133. This allows upward forces to be applied to the steel pipe 121 and the processed steel pipe 1131 at multiple positions along the length, enabling smooth movement of both and ensuring accurate loading and unloading.

[0044] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the steel pipe end grinding device 10 further includes a support adjustment device 14. The support adjustment device 14 is used to adjust the relative position of the support 112 and the rotating grinding disc 113. Each support 112 is fixed to the base 111 by the support adjustment device 14. Depending on the diameter of the steel pipe 121 to be processed, the support adjustment device 14 can adjust the distance between the processed steel pipe 1131 and the turntable 1133 to accommodate steel pipes 1131 of different diameters. The support adjustment device 14 includes an adjustment groove corresponding to the support 112, which is formed on the upper surface of the base 111 in the front-back direction. The support 112 is fixedly connected to the adjustment groove by bolts and can move in the front-back direction within the adjustment groove to change the position of the support center of the support 112 in the front-back direction.

[0045] Combination Figure 1 and Figure 4 As shown, in some embodiments, the steel pipe frame 12 is inclined from top to bottom toward the support 112, so that the steel pipe 121 to be processed has a tendency to move downwards on the steel pipe frame 12 due to gravity. A stop post 122 is provided at the end of the steel pipe frame 12 near the support 112 to stop the steel pipe 121 to be processed, so that the steel pipe 121 to be processed will not fall off the steel pipe frame 12. When the lifting plate 133 moves upward to lift the steel pipe 121 to be processed, due to the downward tendency of the steel pipe 121 itself, the steel pipe 121 to be processed generates an initial velocity under the action of gravity, so as to move smoothly downwards along the first guide plate and reduce jamming.

[0046] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, the technical features of the embodiments described above are not described in detail.

[0047] All possible combinations of the various technical features are described; however, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The foregoing description and accompanying drawings fully illustrate embodiments of this disclosure to enable those skilled in the art to practice them.
