Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe production and transportation, and specifically relates to a pipe clamping and pipe feeding integrated device for steel pipe production and transportation. Background Technique

[0002] Steel pipes are widely used in industrial production and daily life. During their production and processing, they need to be transported between various processes.

[0003] For example, a steel pipe conveying and transferring device for steel pipe production with the publication number of CN118145264A is provided with a flipping structure on the conveyor. The setting of the flipping structure facilitates the adjustment of the angle of the conveyor, which is convenient for cooperating with two blanking vehicles to collect steel pipes and improves the collection efficiency. Due to the shape of the steel pipe, during the transportation process of the steel pipe, it is necessary to clamp and fix the steel pipe for transportation to avoid collisions during transportation. If a limiting clamping structure is directly added, although the steel pipe can be clamped and limited during the transportation process, during the production process of multiple specifications of steel pipes, it is necessary to continuously transport steel pipes of different sizes. Since the size of the steel pipe changes, during the continuous transportation process, it is necessary to adjust the position of the clamping structure according to the size of the steel pipe in order to clamp and position the transportation of steel pipes of different thicknesses. Therefore, during the transportation process of the steel pipe, once the size of the steel pipe changes, it is necessary to re-adjust the clamping mechanism, which is not conducive to the continuity of transportation and reduces the transportation efficiency of the steel pipe, and there are certain defects in use.

[0004] Therefore, we propose a pipe clamping and pipe feeding integrated device for steel pipe production and transportation in order to solve the problems mentioned above. Summary of the Invention

Since the size of the steel pipe changes, during the continuous transportation process, it is necessary to adjust the position of the clamping structure according to the size of the steel pipe in order to clamp and position the transportation of steel pipes of different thicknesses. Therefore, during the transportation process of the steel pipe, once the size of the steel pipe changes, it is necessary to re-adjust the clamping mechanism, which is not conducive to the continuity of transportation and reduces the transportation efficiency of the steel pipe.

[0027] By adopting the above technical solution, the movable ring can be positioned.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: The pipe clamping and conveying integrated device for steel pipe production and conveying enables automatic clamping and positioning of the steel pipe during conveying, avoiding deviation of the steel pipe during conveying, preventing damage to the steel pipe during conveying, and being able to automatically position steel pipes of different thicknesses without adjustment, facilitating continuous conveying of steel pipes of different specifications in the same batch, and ensuring the working efficiency of conveying;

[0029] 1. During the conveying process of the steel pipe, one end of the steel pipe is placed on the right V-shaped roller. Multiple V-shaped rollers are connected in series with the motor through a chain, enabling multiple V-shaped rollers to rotate simultaneously. After the steel pipe is placed on the V-shaped roller, it can drive the steel pipe to convey and move as the V-shaped roller rotates, allowing the steel pipe to enter the inner side of the right fixed frame. If the diameter of the steel pipe is small, it can push the limiting cylinder between the fixed plates to rotate. If the diameter of the steel pipe is large, the movement of the steel pipe can first push the limiting cylinder between the support plates to rotate, and then push the limiting cylinder between the mounting plates to rotate, causing the movement of the steel pipe to lift the limiting cylinder, which can lift the movable plate. After the movable plate is lifted, it drives the mounting rod to slide on the fixed frame, stretching the telescopic spring. The steel pipe is conveyed from right to left and can pass through the limiting cylinder between the fixed plates and then through the limiting cylinder between the mounting plates. After the movable plate moves, the limiting cylinder can be pressed against the steel pipe by the reaction force of the telescopic spring. The steel pipe can be positioned between the V-shaped roller and the limiting cylinder during conveying, avoiding the movement of the steel pipe during conveying. If only the V-shaped roller is used for conveying, since there is no limit at the top during the conveying process of the steel pipe, it may cause displacement and unnecessary scratches during the conveying process of the steel pipe. Through the limiting component, during the conveying of the steel pipe, it can automatically clamp and position the steel pipe, avoiding deviation of the steel pipe during conveying, preventing damage to the steel pipe during conveying, and being able to automatically position steel pipes of different thicknesses without adjustment, facilitating continuous conveying of steel pipes of different specifications in the same batch, and ensuring the working efficiency of conveying;

[0030] 2. When transporting steel pipes or stainless steel pipes with a relatively large diameter and a relatively thin pipe wall, the pipe wall thickness may be about 0.5 mm. When transporting such steel pipes, after the steel pipe jacks up the movable plate and drives the limiting cylinder between the mounting plates to rotate, it can drive the rotating rod to rotate. After the rotating rod rotates, it drives the turntable to rotate. After the turntable rotates, through the sliding connection between the movable groove and the column rod, it can push the movable rod to move, so that the return spring can be stretched. During the movement of the movable rod, it drives the movable block to move, so that the movable block can drive the arc-shaped rod to move. Then, during the rotation of the rotating rod, it drives the arc-shaped rod to rotate. If the arc-shaped rod moves and then rotates in a circle, the rotation range becomes larger. Since the roller abuts against the arc-shaped rod, the movement of the arc-shaped rod can push the roller to move upward, and the roller rotates during the rotation of the arc-shaped rod. After the roller moves upward, it can drive the sliding rod to move, so that the first piston slides in the first cylinder, and the support spring can be stretched, so that the air inside the first cylinder can enter the metal braided hose. The movement of the movable plate can make the metal braided hose continuously approximate to be straightened. Then, the air can enter the second cylinder through the connecting pipe, and then can push the second piston to move, so that the moving rod moves, and then the rubber sleeve moves and fits tightly with one side of the mounting rod. During the transportation of the pipeline, it jacks up the movable plate, and then after the pipeline moves and drives the limiting cylinder between the mounting plates to rotate, it can automatically position the mounting rod. Thus, during the transportation of the pipeline, the mounting rod is prevented from moving. When transporting pipelines with a large diameter and a thin pipe wall, the large pipeline diameter makes the displacement of the movable plate longer, and the reaction force of the limiting cylinder on the pipeline is also larger. Moreover, the contact between the limiting cylinder and the pipeline is a point contact. In the case of a large pressure, it may cause the pipeline to deform during transportation. By positioning with the mounting rod, the mounting rod will not easily move downward, and thus the movable plate and the limiting cylinder will not easily move downward. While ensuring the clamping stability of the pipeline transportation, it avoids damaging the pipeline and improves the practicability;

[0031] 3. When positioning the installation rod for pipeline transportation, before the turntable rotates, the positioning block is inserted into the positioning groove to position the movable ring. During the rotation of the turntable, the movable rod can be driven to move. While the movable rod moves, the moving plate is driven to move. After the moving plate moves, the connection between the sliding groove and the column block can pull the column block to move, causing the connecting plate to move, and then driving the positioning block to leave the positioning groove. At this time, the column rod moves to the limit position and fits with the movable groove, causing the column block to move to the limit distance in the sliding groove. At this time, the positioning block completely disengages from the positioning groove. During the subsequent rotation of the turntable, the movable ring loses its limit. The rotation of the turntable causes the column rod to abut against the movable groove, enabling the movable rod to rotate circumferentially, and then causing the movable ring to rotate. After the steel pipe transportation ends, the abutting force of the movable groove on the column rod disappears, and the movable rod can automatically reset, thereby driving the positioning block to reset, causing the positioning block to be inserted into another positioning groove, enabling the movable ring to be positioned again. The end of the positioning block close to the positioning groove can be set as a spherical shape. Even if the positioning block is not completely aligned with the positioning groove, the contact between the spherical end of the positioning block and the positioning groove facilitates the insertion of the positioning block. Therefore, after positioning the installation rod, the movable ring can rotate with the turntable, facilitating the overall operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figures 1-10 , the present invention provides a technical solution: a pipe clamping and pipe feeding integrated device for steel pipe production and transportation, including a support platform 1, support frames 101 are symmetrically installed at the bottom of the support platform 1, and vertical plates 102 are symmetrically installed at the top of the support platform 1, and a plurality of V-shaped rollers 103 are rotatably connected between the two vertical plates 102;

[0045] It further includes:

[0046] Fixed frames 105, symmetrically arranged above the two vertical plates 102, fixed strips 104 are fixedly installed at the bottom ends of both ends of the two fixed frames 105, and the fixed strips 104 are fixedly connected to the vertical plates 102;

[0047] Limit component 2, arranged inside the fixed frame 105, and the limit component 2 includes a movable plate 201;

[0048] The movable plate 201 is arranged inside the fixed frame 105. Two sets of mounting rods 202 are symmetrically installed at the top of the movable plate 201, and both of the two mounting rods 202 are fixedly connected to the fixed frame 105. At the same time, telescopic springs 203 are sleeved on the upper parts of the two sets of mounting rods 202, and the two ends of the telescopic springs 203 are respectively fixedly connected to the fixed frame 105 and the mounting rods 202.

[0049] On one side of the bottom of the movable plate 201, fixing plates 204 are symmetrically installed. On the other side of the bottom of the movable plate 201, mounting plates 205 are symmetrically installed. On one side of each of the two fixing plates 204, support plates 206 are fixedly installed. At the same time, rotating shafts 207 are rotatably connected between the two fixing plates 204, the two mounting plates 205 and the two support plates 206. A number of limiting plates 208 are fixedly installed on the outer part of the rotating shaft 207, and limiting cylinders 209 are fixedly installed on the sides of the number of limiting plates 208 away from the rotating shaft 207.

[0050] Example 1: As Figures 1-3 shown, during the process of conveying the steel pipe, one end of the steel pipe is placed on the right V-shaped roller 103. A plurality of V-shaped rollers 103 are connected in series with the motor through a chain, so that the plurality of V-shaped rollers 103 can rotate simultaneously. After the steel pipe is placed on the V-shaped roller 103, the rotation of the V-shaped roller 103 can drive the steel pipe to convey and move, so that the steel pipe can enter the inside of the right fixed frame 105. If the diameter of the steel pipe is small, it can push the limiting cylinder 209 between the fixing plates 204 to rotate. If the diameter of the steel pipe is large, the movement of the steel pipe can first push the limiting cylinder 209 between the support plates 206 to rotate, and then push the limiting cylinder 209 between the mounting plates 205 to rotate, so that the movement of the steel pipe can lift the limiting cylinder 209, so that the movable plate 201 can be lifted. After the movable plate 201 is lifted, it drives the mounting rod 202 to slide on the fixed frame 105, and the telescopic spring 203 can be stretched. The steel pipe is conveyed from right to left. The steel pipe can pass through the limiting cylinder 209 between the fixing plates 204 and then through the limiting cylinder 209 between the mounting plates 205. After the movable plate 201 moves, the reaction force of the telescopic spring 203 can make the limiting cylinder 209 press against the steel pipe tightly. During the conveying process of the steel pipe, it can be positioned between the V-shaped roller 103 and the limiting cylinder 209, avoiding the movement of the steel pipe during the conveying process. If only the V-shaped roller 103 is used for conveying, since there is no limit on the top of the steel pipe during the conveying process, it may cause the displacement of the steel pipe during the conveying process and unnecessary scratches. Through the limiting component 2, when the steel pipe is conveyed, the steel pipe can be automatically clamped and positioned, avoiding the deviation of the steel pipe during the conveying process, avoiding the damage of the steel pipe during the conveying process, and can automatically position steel pipes of different thicknesses without adjustment, which is convenient for continuously conveying steel pipes of different specifications in the same batch and ensuring the conveying work efficiency.

[0051] The positioning component 3 is symmetrically arranged on both sides of the movable plate 201;

[0052] The positioning component 3 includes rotating rods 301 that are symmetrically and rotatably connected inside two mounting plates 205. The rotating shafts 207 between the two rotating rods 301 and the two mounting plates 205 are fixedly connected. At the far ends of the two rotating rods 301 away from each other, turntables 302 are fixedly installed. On one side of the turntable 302, two groups of movable slots 303 are symmetrically penetrated. On the outer side of one side of the rotating rod 301, a movable ring 304 is sleeved. On the outer side of the movable ring 304, two groups of positioning frames 305 are symmetrically installed. Inside one side of the positioning frame 305, a movable rod 306 is slidably connected. On one side of the movable rod 306, a column rod 307 is fixedly installed. The column rod 307 is slidably connected with the movable slot 303;

[0053] At the far ends of the two groups of movable rods 306 away from the rotating rod 301, movable blocks 308 are fixedly installed. On the outer side of the movable rod 306 on the side of the movable block 308, a return spring 309 is sleeved. The two ends of the return spring 309 are respectively fixedly connected with the movable block 308 and the positioning frame 305. Inside one side of the movable block 308, a guide rod 310 is slidably connected. The guide rod 310 is fixedly connected with the positioning frame 305;

[0054] On both sides of the two groups of movable blocks 308, arc-shaped rods 311 are fixedly installed. Above the top of the movable plate 201 and on one side above the two mounting plates 205, first cylinders 312 are symmetrically installed. Inside the first cylinder 312, a first piston 313 is slidably connected. At the bottom of the first piston 313, a sliding rod 314 is fixedly installed. Above the outer side of the sliding rod 314, a support spring 315 is sleeved. The two ends of the support spring 315 are respectively fixedly connected with the first piston 313 and the movable plate 201. At the bottom of the sliding rod 314, a mounting frame 316 is fixedly installed. On both sides of the mounting frame 316, rollers 317 are symmetrically and rotatably connected. The two groups of rollers 317 are abutted against the upper arc-shaped rods 311;

[0055] Above one side of the two first cylinders 312, a metal braided hose 318 is penetrated and connected. On the inner top of the fixed frame 105, second cylinders 319 are symmetrically installed. On one side of the two second cylinders 319, connecting pipes 320 are penetrated and connected. The metal braided hose 318 is penetrated and connected with the connecting pipe 320. Inside the second cylinder 319, a second piston 321 is slidably connected. On one side of the second piston 321, a moving rod 322 is fixedly installed. The moving rod 322 is slidably connected with the second cylinder 319. At the far end of the moving rod 322 away from the second piston 321, a rubber sleeve 323 is fixedly installed;

[0056] A rotating ring 3041 is fixedly installed on one side of the movable ring 304 close to the mounting plate 205. A limiting ring groove 3042 is formed on one side of the mounting plate 205, and the rotating ring 3041 is slidably connected to the limiting ring groove 3042.

[0057] Embodiment 2: As Figures 2-8 shown, when conveying a steel pipe or a stainless steel pipe with a relatively large diameter and a relatively thin pipe wall, the pipe wall thickness may be about 0.5 mm. When conveying such a steel pipe, after the steel pipe jacks up the movable plate 201 and drives the limiting cylinder 209 between the mounting plates 205 to rotate, the rotating rod 301 can be driven to rotate. After the rotating rod 301 rotates, the turntable 302 is driven to rotate. After the turntable 302 rotates, the sliding connection between the movable groove 303 and the column rod 307 can push the movable rod 306 to move, so that the return spring 309 can be stretched. During the movement of the movable rod 306, the movable block 308 is driven to move, so that the movable block 308 can drive the arc rod 311 to move. Then, during the rotation of the rotating rod 301, the arc rod 311 is driven to rotate. If the arc rod 311 moves and then rotates in a circular motion, the rotation range becomes larger. Since the roller 317 abuts against the arc rod 311, the roller 317 can be pushed upward to move through the movement of the arc rod 311. And during the rotation of the arc rod 311, the roller 317 rotates. After the roller 317 moves upward, the sliding rod 314 can be driven to move, so that the first piston 313 slides in the first cylinder body 312, and the support spring 315 can be stretched, so that the air inside the first cylinder body 312 can enter the metal braided hose 318. The movement of the movable plate 201 can make the metal braided hose 318 continuously approximate to be straightened. Then, the air can enter the second cylinder body 319 through the connecting pipe 320, and then the second piston 321 can be pushed to move, so that the moving rod 322 moves, and then the rubber sleeve 323 moves to closely fit with one side of the mounting rod 202. During the conveying process of the pipeline, the pipeline jacks up the movable plate 201 and moves upward. After the pipeline moves and drives the limiting cylinder 209 between the mounting plates 205 to rotate, the mounting rod 202 can be automatically positioned, so as to avoid the movement of the mounting rod 202 during the conveying process of the pipeline. When conveying a pipeline with a large diameter and a thin pipe wall, the large diameter of the pipeline makes the displacement of the movable plate 201 longer, and the reaction force of the limiting cylinder 209 on the pipeline is also greater. And the contact between the limiting cylinder 209 and the pipeline is a point contact. Under the condition of greater pressure, the pipeline may be deformed during the conveying process. By positioning with the mounting rod 202, the mounting rod 202 will not easily move downward. Furthermore, the movable plate 201 and the limiting cylinder 209 will not easily move downward. While ensuring the clamping stability of the pipeline conveying, damage to the pipeline is avoided, and the practicability is improved.

[0058] On one side of the two movable rods 306 close to the mounting plate 205, moving plates 324 are fixedly installed. A sliding groove 327 is formed through one side of the moving plate 324. A column block 326 is slidably connected inside the sliding groove 327. At the same time, connecting frames 325 are fixedly installed at both ends of the column block 326. Moreover, the two connecting frames 325 are slidably connected to the positioning frame 305;

[0059] On one side of the two connecting frames 325, a connecting plate 328 is fixedly installed. On one side of the connecting plate 328 close to the mounting plate 205, a positioning block 329 is fixedly installed. A number of positioning grooves 330 are formed outside the mounting plate 205 on the outer side of the limit ring groove 3042. At the same time, the positioning block 329 is snap-fitted with the positioning groove 330.

[0060] Embodiment 3: As Figures 3-5 and Figures 9-10 shown, when positioning the mounting rod 202 by pipeline transportation, before the turntable 302 rotates, the positioning block 329 is inserted into the positioning groove 330 to position the movable ring 304. After that, during the rotation of the turntable 302, the movable rod 306 can be driven to move. While the movable rod 306 moves, the moving plate 324 is driven to move. After the moving plate 324 moves, the connection between the sliding groove 327 and the column block 326 can pull the column block 326 to move, so that the connecting plate 328 moves, and then the positioning block 329 can be driven to leave the positioning groove 330. At this time, the column rod 307 moves to the limit position and fits with the movable groove 303, so that the column block 326 moves to the limit distance in the sliding groove 327. At this time, the positioning block 329 just completely disengages from the positioning groove 330. After that, during the rotation of the turntable 302, the movable ring 304 loses its limit. The rotation of the turntable 302 causes the column rod 307 to abut against the movable groove 303, so that the movable rod 306 can be driven to rotate circumferentially, and then the movable ring 304 can be rotated. After the steel pipe transportation is completed, the abutting force of the movable groove 303 on the column rod 307 disappears, and the movable rod 306 can automatically reset, and then the positioning block 329 can be driven to reset, so that the positioning block 329 is inserted into another positioning groove 330, so that the movable ring 304 can be positioned again. And the end of the positioning block 329 close to the positioning groove 330 can be set to be spherical. Even if the positioning block 329 is not completely aligned with the positioning groove 330, the contact between the spherical end of the positioning block 329 and the positioning groove 330 is convenient for the insertion of the positioning block 329. Therefore, after positioning the mounting rod 202, the movable ring 304 can rotate together with the turntable 302, which is convenient for the overall operation.

[0061] Working principle: When using the pipe clamping and pipe conveying integrated device for steel pipe production and transportation, first, according to Figures 1-10As shown in the figure, during the transportation of the steel pipe, one end of the steel pipe is placed on the right V-shaped roller 103. Multiple V-shaped rollers 103 are connected in series with the motor through a chain, so that multiple V-shaped rollers 103 can rotate simultaneously. After the steel pipe is placed on the V-shaped roller 103, the rotation of the V-shaped roller 103 can drive the steel pipe to be transported and move, enabling the steel pipe to enter the inner side of the right fixed frame 105. If the diameter of the steel pipe is small, it can push the limiting cylinder 209 between the fixed plates 204 to rotate. If the diameter of the steel pipe is large, the movement of the steel pipe can first push the limiting cylinder 209 between the support plates 206 to rotate, and then push the limiting cylinder 209 between the mounting plates 205 to rotate, so that the movement of the steel pipe can lift the limiting cylinder 209, enabling the movable plate 201 to be lifted. After the movable plate 201 is lifted, it drives the mounting rod 202 to slide on the fixed frame 105, stretching the telescopic spring 203. The steel pipe is transported from right to left, and the steel pipe can pass through the limiting cylinder 209 between the fixed plates 204 and then through the limiting cylinder 209 between the mounting plates 205. After the movable plate 201 moves, the reaction force of the telescopic spring 203 can make the limiting cylinder 209 press against the steel pipe. During the transportation process, the steel pipe can be positioned between the V-shaped roller 103 and the limiting cylinder 209, preventing the steel pipe from moving during transportation. If only the V-shaped roller 103 is used for transportation, since there is no limit at the top during the transportation of the steel pipe, it may cause the steel pipe to shift during transportation, resulting in unnecessary scratches. Through the limiting component 2, when transporting the steel pipe, it can automatically clamp and position the steel pipe, preventing the steel pipe from shifting during transportation and avoiding damage to the steel pipe during transportation. Moreover, it can automatically position steel pipes of different thicknesses without adjustment, facilitating the continuous transportation of steel pipes of different specifications in the same batch and ensuring the working efficiency of transportation;

[0062] When transporting steel pipes or stainless steel pipes with a relatively large diameter and a relatively thin pipe wall, the pipe wall thickness may be about 0.5 mm. When transporting such steel pipes, after the pipe jacks up the movable plate 201 and drives the limiting cylinder 209 between the mounting plates 205 to rotate, it can drive the rotating rod 301 to rotate. After the rotating rod 301 rotates, it drives the turntable 302 to rotate. After the turntable 302 rotates, through the sliding connection between the movable groove 303 and the column rod 307, it can push the movable rod 306 to move, so that the return spring 309 can be stretched. During the movement of the movable rod 306, it drives the movable block 308 to move, so that the movable block 308 can drive the arc rod 311 to move. Then, during the rotation of the rotating rod 301, it drives the arc rod 311 to rotate. If the arc rod 311 moves and then rotates in a circle, the rotation range becomes larger. Since the roller 317 abuts against the arc rod 311, the movement of the arc rod 311 can push the roller 317 to move upward, and the roller 317 rotates during the rotation of the arc rod 311. After the roller 317 moves upward, it can drive the sliding rod 314 to move, so that the first piston 313 slides in the first cylinder 312, and the support spring 315 can be stretched, so that the air inside the first cylinder 312 can enter the metal braided hose 318. The movement of the movable plate 201 can make the metal braided hose 318 continuously approximate to be straightened. Then, the air can enter the second cylinder 319 through the connecting pipe 320, and then can push the second piston 321 to move, so that the moving rod 322 moves, and then the rubber sleeve 323 moves and closely fits with one side of the mounting rod 202. During the transportation of the pipeline, the pipeline jacks up the movable plate 201 and moves upward. After the pipeline moves and drives the limiting cylinder 209 between the mounting plates 205 to rotate, it can automatically position the mounting rod 202. Thus, during the transportation of the pipeline, the mounting rod 202 is prevented from moving. When transporting a pipeline with a large diameter and a thin pipe wall, the large pipeline diameter makes the displacement of the movable plate 201 longer, and the reaction force of the limiting cylinder 209 on the pipeline is also greater. Moreover, the contact between the limiting cylinder 209 and the pipeline is a point contact. In the case of a large pressure, it may cause the pipeline to deform during transportation. By positioning with the mounting rod 202, the mounting rod 202 will not easily move downward. Thus, the movable plate 201 and the limiting cylinder 209 will not easily move downward. While ensuring the clamping stability of the pipeline transportation, it avoids damaging the pipeline and improves the practicability. When the pipeline transportation positions the mounting rod 202, before the turntable 302 rotates, the positioning block 329 is inserted into the positioning slot 330 to position the movable ring 304. Then, during the rotation of the turntable 302, it can drive the movable rod 306 to move. While the movable rod 306 moves, it drives the moving plate 324 to move. After the moving plate 324 moves, through the connection between the sliding slot 327 and the column block 326, it can pull the column block 326 to move, so that the connecting plate 328 moves, and then can drive the positioning block 329 to leave the positioning slot 330. At this time, the column rod 307 moves to the limit position and fits with the movable groove 303.The column block 326 is moved to the limit distance within the sliding groove 327. At this time, the positioning block 329 is just completely disengaged from the positioning groove 330. After that, during the rotation of the turntable 302, the movable ring 304 loses its limit. The rotation of the turntable 302 causes the column rod 307 to abut against the movable groove 303, enabling the circumferential rotation of the movable rod 306, and further causing the rotation of the movable ring 304. After the steel pipe conveying is completed, the abutting force of the movable groove 303 on the column rod 307 disappears, and the movable rod 306 can automatically reset, thereby driving the positioning block 329 to reset, making the positioning block 329 inserted into another positioning groove 330, enabling the repositioning of the movable ring 304. Moreover, the end of the positioning block 329 close to the positioning groove 330 can be set as a spherical shape. Even if the positioning block 329 is not completely aligned with the positioning groove 330, the contact between the spherical end of the positioning block 329 and the positioning groove 330 facilitates the insertion of the positioning block 329. Thus, after the installation rod 202 is positioned, the movable ring 304 can rotate together with the turntable 302, facilitating the overall operation.,
