Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for steel pipe processing, specifically to a feeding, conveying, and storage device and driving method for cleaned steel pipes. Background Technology

[0002] Before production, processing, and use, steel pipes typically undergo a cleaning process to remove surface oil, rust, and impurities, ensuring surface quality and the precision of subsequent processing and assembly. After cleaning, the steel pipes must be systematically unloaded, transported, and centrally stored before proceeding to subsequent transfers, hoisting, or the next process. The efficiency of the unloading and storage process directly affects the continuity of the entire steel pipe processing line.

[0003] In existing technologies, the unloading of cleaned steel pipes mostly relies on manual pushing or simple chute descent. Manual pushing is not only labor-intensive and inefficient, but also prone to damage due to uneven pushing force, affecting product qualification rate. While simple chutes allow steel pipes to slide down on their own, they lack effective guiding and limiting structures, making it easy for pipes to deviate from their trajectory during descent, and even causing jamming and stacking problems, requiring frequent manual intervention. Furthermore, existing unloading methods cannot automatically count the number of unloaded steel pipes, relying heavily on manual counting, resulting in high error rates and failing to meet the needs of refined production management. Moreover, unloaded steel pipes are often directly piled on the ground or in simple storage boxes, easily becoming scattered and bumped during stacking, requiring manual re-sorting and stacking during subsequent hoisting, further increasing the workload and reducing transfer efficiency. The supporting storage structures are mostly fixed storage boxes, requiring manual handling and stacking of each pipe to the hoisting position after filling, failing to achieve seamless connection between storage and hoisting, and lacking protection for the steel pipes during storage, easily causing secondary damage to the pipe surface. In addition, existing feeding and storage devices are mostly designed separately, with poor connection. Steel pipes are prone to falling or getting stuck during the transfer process from feeding to storage. The overall level of automation is low, making it difficult to meet the high-efficiency operation requirements of modern steel pipe processing production lines.

[0004] In summary, there is an urgent need for an integrated device that can achieve orderly unloading, accurate counting, safe storage, and convenient hoisting preparation of cleaned steel pipes, in order to solve the problems of high labor intensity, low efficiency, inaccurate counting, and easy damage to steel pipes in existing technologies. Summary of the Invention

[0005] In order to solve the problems existing in the background art, the present invention provides a feeding, conveying and storage device and driving method for cleaned steel pipes.

[0006] The technical solution adopted in this invention is: 1. A material conveying and storage device for cleaned steel pipes. It includes multiple parallel and identical feeding, conveying and storage mechanisms, each of which includes a feeding module, a feeding rack, a pneumatic storage rack and a feeding sensing component; The unloading rack is arranged horizontally at an incline. One end connected to the pneumatic storage rack is the low end, and the other end connected to the unloading module is the high end. The unloading module is used to push the steel pipe to be unloaded into the unloading rack. The unloading sensing component is installed on the unloading rack to detect the steel pipe to be unloaded.

[0007] The unloading module includes an unloading flap, a flap shaft, an unloading guard plate, a hydraulic cylinder, a cylinder support, a cylinder mounting plate, an unloading frame guard plate, and an unloading sensing component. The unloading frame includes an unloading frame guard plate and an unloading frame frame. The unloading frame frame is divided into two layers. The upper end of the upper layer of the unloading frame frame is fixedly connected to the unloading frame guard plate for contact with the steel pipe to be unloaded. The upper layer of the unloading frame frame is arranged in an inclined horizontal position so that the steel pipe to be unloaded rolls from the high end to the low end. The end of the upper layer connected to the unloading module is the high end. A pair of unloading flaps are symmetrically and movably connected to the high end so that each unloading flap swings around the high end. The two unloading flaps are fixedly connected by a flap shaft so that the two unloading flaps swing synchronously. The upper end of each unloading flap is fixedly installed with the unloading guard plate for contact with the steel pipe to be unloaded. The material feeding sensing component is fixed to one side of the high end of the material feeding frame; A hydraulic cylinder mounting plate is fixedly installed on the lower layer of the unloading frame. The hydraulic cylinder is fixedly installed on the hydraulic cylinder mounting plate through a hydraulic cylinder support. The output end of the hydraulic cylinder is connected to one of the unloading flaps to drive the unloading flap to swing.

[0008] The feeding module also includes a feeding baffle, a cylinder guide seat, and a feeding baffle cylinder; The feeding rack frame and the pneumatic storage rack are connected at one end as the low end, and the feeding baffle cylinder is arranged on one side of the low end. The output end of the feeding baffle cylinder is fixedly connected upward to the lower end of the feeding baffle. The feeding baffle is slidably set on one side of the low end of the feeding rack frame through the cylinder guide seat. The output end of the feeding baffle cylinder drives the feeding baffle to make horizontal reciprocating linear motion along the cylinder guide seat.

[0009] The feeding sensing component includes a feeding sensing component mounting base, a touch lever, a feeding sensing bracket, a proximity switch, a proximity sensing bolt, a limit bolt, a tension spring, and a lever shaft; One side of the material feeding sensor component mounting base is fixed to the high end of the material feeding frame. On the other side of the material feeding sensor component mounting base, a contact lever is rotatably connected via a lever shaft, causing the contact lever to swing around the lever shaft. The upper end of the contact lever extends upward beyond the upper layer of the material feeding frame to contact the steel pipe to be fed. A tension spring for resetting is connected between the lower end of the contact lever and the material feeding sensor component mounting base. The proximity switch is also fixedly installed on the material feeding sensor component mounting base via a material feeding sensor bracket. The proximity sensing bolt is installed on the contact lever and swings with the contact lever. When the proximity sensing bolt is in the initial position, it is set corresponding to the proximity switch. The material feeding sensor component mounting base is also provided with a limit bolt to limit the contact lever to maintain the initial position.

[0010] The proximity switch has a sensing end and a proximity sensing bolt installed on the touch lever as the trigger end. When initially positioned, the trigger end is on the same horizontal straight line. The trigger end moves closer to or away from the proximity switch as the touch lever swings.

[0011] The pneumatic storage rack includes a storage frame body, a pin shaft, a storage frame rubber plate, a tape tensioning cylinder, a tape tensioning cylinder mounting support, and a rotating sleeve. The storage frame is U-shaped, and one end is fixedly connected to the lower end of the unloading frame. The coil tensioning cylinder is fixedly installed at one end of the bottom of the storage frame through a tensioning cylinder mounting bracket. There are three pins that are respectively installed through the storage frame. One of them is the first pin located at the other end of the bottom of the storage frame. The other two are the second pin and the third pin, which are symmetrically arranged on the top two sides of the storage frame. The second pin is located above the first pin. Each pin is fitted with a rotating sleeve. The upper surface of the storage frame is provided with a storage frame rubber plate to reduce the impact caused by the falling steel pipe.

[0012] The pneumatic storage rack also includes a tape reel; One end of the tape is connected to the output end of the tape tensioning cylinder, and passes sequentially around the rotating sleeve of the first pin and the rotating sleeve of the second pin and is fixed on the rotating sleeve of the third pin, so that the tape tensioning cylinder pulls the tape to tighten or loosen between the second pin and the third pin. When the tape is unwinding, it hangs down between the second and third pins within the U-shaped groove of the storage frame; when the tape is tightening, it is taut between the second and third pins to form a horizontal straight line for placing the steel pipe to be unloaded.

[0013] II. A driving method for a material feeding, conveying, and storage device for cleaned steel pipes. The driving method includes: Multiple feeding, conveying, and storage mechanisms move simultaneously and synchronously. The feeding module pushes the steel pipe to be fed onto the feeding rack. The steel pipe rolls from the high end to the low end of the feeding rack, and the feeding sensor counts as it passes the feeding sensor. After the steel pipe reaches the low end, it is intercepted by the feeding baffle. Then, the feeding baffle descends to allow the steel pipe to enter the pneumatic storage rack. The feeding sensor provides feedback on the number of steel pipes to be fed. When the number of steel pipes to be fed reaches a preset number, the initially relaxed belt of the pneumatic storage rack tightens to support the steel pipe.

[0014] The driving method is specifically as follows: Step 1: The output end of the hydraulic cylinder extends and drives the two unloading flaps to swing simultaneously, pushing multiple steel pipes to be unloaded on the two unloading flaps into the unloading frame. The multiple steel pipes to be unloaded roll from the high end to the low end of the unloading frame, and each steel pipe to be unloaded collides with the touch lever, causing the touch lever to swing, thereby driving the trigger end of the proximity sensing bolt on the touch lever away from the sensing end of the proximity switch, thus determining that one steel pipe to be unloaded has rolled over, thereby obtaining the number of steel pipes to be unloaded that have rolled over. After the unloading steel pipe has rolled over, the touch lever is brought back to the initial position by the tension spring, preparing for the next steel pipe to be unloaded to roll over. Step 2: When the steel pipe to be unloaded moves to the low end, it is stopped by the unloading baffle. The unloading baffle is lowered by the unloading baffle cylinder, so that the steel pipe to be unloaded continues to move into the U-shaped groove of the storage frame of the pneumatic storage rack. When the number of steel pipes to be unloaded that have passed through the unloading sensing component reaches the preset number, the winding tensioning cylinder pulls the winding belt between the second pin and the third pin to tighten and support the steel pipe to be unloaded.

[0015] The device uses a hydraulic cylinder to flip up a feeding flap, causing the steel pipes in the feeding position to be flipped to the top of the inclined feeding frame. The pipes then roll towards the pneumatic storage rack. As they roll, they pass the feeding sensor component. The pipes pass over a touch lever in the sensor component, causing a proximity sensor bolt mounted on the lever to briefly move away from the proximity switch's detection area. The proximity switch detects the pipe's movement by this brief movement and uploads the signal to the terminal to record the number of pipes fed. The terminal then controls the feeding baffle cylinder to move the feeding baffle along the cylinder guide seat, causing the steel pipes to roll into the pneumatic storage box. Once the storage box is full, the storage cylinder activates, tightening the conveyor belt and lifting the steel pipes so that workers can hoist the cleaned steel pipe assembly away, completing the feeding-storage-feeding process.

[0016] The beneficial effects of this invention are: This device automates the entire process of steel pipe preparation, from material cutting and counting to storage and hoisting preparation, significantly improving operational efficiency and accuracy.

[0017] This invention achieves multiple core advantages through an innovatively designed material feeding sensing component: First, it employs a triggering method that combines mechanical contact with a proximity switch. The rolling of the steel pipe presses against the contact lever, causing the proximity sensing bolt to disengage from the proximity switch's detection area. This ensures accurate signal feedback, avoids false triggering caused by environmental interference, and achieves zero-error material feeding statistics, meeting the needs of refined management. Second, the component uses limit bolts to position itself initially, and a tension spring ensures immediate reset. The structure is robust and impact-resistant, adaptable to complex operating environments, and has a long service life. Third, the sensing signal is intelligently linked with the material feeding baffle cylinder, achieving automated "counting-material control" coordination, preventing steel pipe congestion and stacking, and improving operational efficiency. Fourth, the component has a compact structure and modular assembly, making installation and maintenance convenient without requiring significant modifications to the production line, resulting in outstanding practicality and economy.

[0022] A feeding, conveying and storage device for cleaned steel pipes includes multiple parallel and identical feeding, conveying and storage mechanisms. Each feeding, conveying and storage mechanism includes a feeding module, a feeding rack 2, a pneumatic storage rack 3 and a feeding sensing component 209. The feeding racks 2 of each feeding conveying and storage mechanism are arranged horizontally and at an incline. One end connected to the pneumatic storage rack 3 is the low end, and the other end connected to the feeding module is the high end. The feeding module is used to push the steel pipe 1 to be fed into the feeding rack 2. The high end of the feeding rack 2 is adapted to connect with the steel pipe at the feeding station, and the low end is correspondingly matched with the pneumatic storage rack 3 to form a material guiding channel from the steel pipe to the pneumatic storage rack 3. The feeding sensing component 209 is installed on the feeding rack 2 to detect the steel pipe 1 to be fed.

[0023] The unloading module includes an unloading flap 202, a flap shaft 203, an unloading guard plate 204, a hydraulic cylinder 205, a cylinder support 206, a cylinder mounting plate 207, an unloading frame guard plate 208, and an unloading sensing component 209. The unloading frame 2 includes an unloading frame guard plate 208 and an unloading frame 201. The unloading frame 201 is divided into two layers. The unloading frame guard plate 208 is fixedly connected to the upper top frame of the upper layer of the unloading frame 201 for contact with the steel pipe 1 to be unloaded. The upper layer of the unloading frame 201 is inclined. The horizontal arrangement allows the steel pipe 1 to be unloaded to roll from the high end to the low end. The end connected to the upper layer and the unloading module is the high end. A pair of unloading flaps 202 are symmetrically and movably connected to the high end, so that each unloading flap 202 swings around the high end. The two unloading flaps 202 are fixedly connected by a flap shaft 203 so that the two unloading flaps 202 swing synchronously. An unloading guard plate 204 is fixedly installed on the upper end of each unloading flap 202 and moves synchronously with the unloading flap 202 to contact the steel pipe 1 to be unloaded. The unloading flap 202 has an arc-shaped plate structure, and the unloading guard plate 204 is detachably bolted to the unloading flap 202. A pair of unloading flaps 202 are assembled onto the flap shaft 203 via keyways.

[0024] The feeding sensor component 209 is fixed to the high end of the feeding frame 201 via the mounting hole 220 and the mounting bolt 221; A hydraulic cylinder mounting plate 207 is fixedly installed on the bottom frame of the lower layer of the unloading frame 201. The hydraulic cylinder 205 is fixedly installed on the hydraulic cylinder mounting plate 207 through the hydraulic cylinder support 206. The output end of the hydraulic cylinder 205 is connected to one of the unloading flaps 202 to drive the unloading flap 202 to swing. Specifically, the lower end of the unloading flap 202 extends downward and is fixedly connected to the plunger of the hydraulic cylinder 205.

[0025] After installation, the hydraulic cylinder 205 is tilted at an angle of 8° to the ground, and the cylinder support 206 ensures the required angle after installation. The unloading rack 2 is tilted at an angle of 2° to the ground, with the high end face flush with the discharge end of the steel pipe 1 to be unloaded, and the low end face correspondingly attached to the feed end of the pneumatic storage rack 3.

[0026] The unloading module also includes an unloading baffle 210, a cylinder guide seat 211, and an unloading baffle cylinder 212; The feeding rack frame 201 and the pneumatic storage rack 3 are connected at one end as the low end. The feeding baffle cylinder 212 is arranged on one side frame of the lower layer of the low end. The output end of the feeding baffle cylinder 212 is fixedly connected to the lower end of the feeding baffle 210. The feeding baffle 210 is slidably set on one side frame of the low end of the feeding rack frame 201 through the cylinder guide seat 211. The output end of the feeding baffle cylinder 212 drives the feeding baffle 210 to make horizontal reciprocating linear motion along the cylinder guide seat 211 to realize the opening and closing of the feeding channel.

[0027] Specifically, the discharge baffle cylinder 212 is arranged vertically, with its cylinder body fixed to the side frame of the discharge frame 201, and the piston rod end fixedly connected to a section of the discharge baffle 210. The discharge baffle 210 moves horizontally and reciprocally along the cylinder guide seat 211 to realize the opening and closing of the discharge channel.

[0028] The material feeding sensing component 209 includes a material feeding sensing component fixing base 213, a touch lever 214, a material feeding sensing bracket 215, a proximity switch 216, a proximity sensing bolt 217, a limit bolt 218, a tension spring 219, and a lever shaft 222. One side of the material feeding sensor mounting base 213 is fixed to the high end of the material feeding frame 201 via mounting holes 220 and mounting bolts 221. On the other side of the material feeding sensor mounting base 213, a vertically arranged contact lever 214 is rotatably connected via a horizontally arranged lever shaft 222, causing the contact lever 214 to swing around the lever shaft 222. The upper end of the contact lever 214 extends upwards beyond the upper layer of the material feeding frame 201 to contact the steel pipe 1 to be fed. The lower end of the contact lever 214 and the material feeding sensor... A tension spring 219 for resetting is connected between the component mounting bases 213. A proximity switch 216 is also fixedly installed on the unloading sensor component mounting base 213 via an unloading sensor bracket 215. A proximity sensing bolt 217 is installed on the touch lever 214 and swings together with the touch lever 214. When the proximity sensing bolt 217 is in the initial position, it is set to correspond to the proximity switch 216. A limit bolt 218 is also provided on the unloading sensor component mounting base 213 to limit the touch lever 214 to maintain the initial position.

[0029] The proximity switch 216 has a sensing end and the proximity sensing bolt 217 mounted on the touch lever 214 serves as the trigger end. When initially positioned, they are on the same horizontal straight line. The trigger end moves closer to or away from the proximity switch 216 as the touch lever 214 swings.

[0030] The pneumatic storage rack 3 includes a storage frame body 301, a pin 302, a storage frame rubber plate 303, a tape tensioning cylinder 305, a tape tensioning cylinder mounting support 306, and a rotating sleeve 307. The storage frame 301 serves as the supporting structure for the pneumatic storage rack 3. The storage frame 301 is U-shaped, and one end is fixedly connected to the lower end of the unloading rack frame 201. The tape tensioning cylinder 305 is fixedly installed at one end of the bottom of the storage frame 301 via a tensioning cylinder mounting bracket 306, and the cylinder end of the tape tensioning cylinder 305 is fixedly connected to the tensioning cylinder mounting bracket 306. There are three pins 302, which are respectively installed through the storage frame 301. One of them is the first pin, which is located at the other end of the bottom of the storage frame 301 where the tape tensioning cylinder 305 is installed and is parallel to the piston rod end of the tape tensioning cylinder 305. The other two are the second pin and the third pin, which are symmetrically arranged on the top two sides of the storage frame 301, with the second pin located above the first pin. Each pin 302 is fitted with a rotating sleeve 307. The upper end of the storage frame 301 is provided with a storage frame rubber plate 303 to reduce the impact caused by the falling of the steel pipe 1 to be unloaded.

[0031] The pneumatic storage rack 3 also includes a winding belt 304. One end of the winding belt 304 is connected to the output piston rod end of the winding belt tensioning cylinder 305, and passes sequentially around the rotating sleeves 307 of the first and second pins and is fixed to the rotating sleeve 307 of the third pin. Specifically, the upper end of the storage frame rubber plate 303 has two holes parallel to the two pins 302 located at the upper end of the storage frame body 301, for the winding belt 304 to pass through. After passing through the rotating sleeve 307 of the first pin, it passes around the rotating sleeve 307 of the second pin and passes through the hole in the storage frame rubber plate 303, is arranged on the upper surface of the storage frame rubber plate 303, and then enters from the hole at the other end and is fixedly installed on the rotating sleeve 307 of the third pin. This allows the winding belt tensioning cylinder 305 to pull the winding belt 304 to tighten or loosen between the second and third pins. When the coil 304 is unwinding, it hangs down between the second and third pins in the U-shaped groove of the storage frame 301; when the coil 304 is taut, it is stretched straight between the second and third pins to form a horizontal straight line for placing the steel pipe 1 to be unloaded.

[0032] A driving method for a feeding, conveying, and storage device for cleaned steel pipes includes: Multiple feeding, conveying, and storage mechanisms move simultaneously and synchronously. The feeding module pushes the steel pipe 1 to be fed onto the feeding rack 2. Due to gravity, the steel pipe 1 rolls from the high end to the low end of the feeding rack 2. When it passes the feeding sensor component 209, the feeding sensor component 209 counts. After the steel pipe 1 reaches the low end, it is intercepted by the feeding baffle 210. Then, the feeding baffle 210 descends, allowing the steel pipe 1 to enter the pneumatic storage rack 3. The feeding sensor component 209 provides feedback on the number of steel pipes to be fed. When the number of steel pipes to be fed reaches the preset number, the initially relaxed winding belt 304 of the pneumatic storage rack 3 is tightened to support the steel pipe 1 for easy access by workers.

[0033] The specific driving method is as follows: Step 1: When the steel pipe 1 to be unloaded is cleaned and located at the unloading station, the hydraulic cylinder 205 is activated. The output end of the hydraulic cylinder 205 extends, causing the two unloading flaps 202 to swing simultaneously, pushing the multiple steel pipes 1 to be unloaded on the two unloading flaps 202 into the unloading frame 201. The multiple steel pipes 1 to be unloaded roll from the high end to the low end of the unloading frame 201, and each steel pipe 1 to be unloaded collides with the touch lever 214, causing the touch lever 214 to swing, thereby causing the trigger end of the proximity sensing bolt 217 on the touch lever 214 to move away from the sensing end of the proximity switch 216, thus indicating that one steel pipe 1 to be unloaded has rolled past. The number of steel pipes 1 that have rolled over is obtained. After each steel pipe 1 has rolled over, it touches lever 214 and is brought back to its initial position by tension spring 219, preparing for the next steel pipe 1 to roll over. Specifically, the piston rod of the hydraulic cylinder extends. Since the piston rod is connected to the lower end of the unloading flap 202, when the piston rod extends, the unloading flap 202 rotates upward around the flap axis 203. When the unloading flap 202 flips upward, it contacts the steel pipe at the unloading station and drives it to contact the unloading frame guard plate 208 and be located at the high end of the unloading frame 201. Then, the hydraulic cylinder 205 returns the unloading flap 202 back. Because the unloading frame is angled, the steel pipe will roll forward towards the lower end under the action of gravitational potential energy. As the steel pipe rolls along the unloading rack under the influence of gravity, it passes over the touch lever 214 in the unloading sensing component 209. When the touch lever 214 is pressed down, the proximity sensing bolt 217 installed at the lower end of the touch lever 214 rises and moves away from the proximity switch 216 that was originally positioned opposite it. After the steel pipe rolls past, the touch lever 214 is pulled back by the tension spring 219, and the proximity sensing bolt 217 moves back towards the proximity switch 216 that was originally positioned opposite it. In this way, the proximity switch obtains a signal that the steel pipe has rolled past and uploads the signal to the terminal to record the number of steel pipes unloaded. Then, it controls the unloading baffle cylinder to move along the cylinder guide seat, so that the steel pipe rolls smoothly into the pneumatic storage box.

[0034] Step 2: When the steel pipe 1 to be unloaded moves to the low end, it is stopped by the unloading baffle 210 to reduce the impact force of the steel pipe 1 to be unloaded onto the pneumatic storage rack 3. The unloading baffle 210 is driven to descend by the unloading baffle cylinder 212, so that the steel pipe 1 to be unloaded continues to move into the U-shaped groove of the storage frame 301 of the pneumatic storage rack 3. When the number of steel pipes 1 to be unloaded that have passed through the unloading sensing component 209 reaches the preset number, the winding tensioning cylinder 305 pulls the winding belt 304 to tighten and support the steel pipe 1 to be unloaded between the second pin and the third pin, so that the worker can pick it up. Specifically, after the steel pipe rolls into the pneumatic storage rack 3, if the terminal records that the number has reached the limit for the number that can be hoisted, the winding tension cylinder 305 is controlled to work, and the piston rod retracts to drive the winding 304 to tighten. Due to the arrangement design of the winding 304 and the rotating sleeve 307, the steel pipe is lifted by the winding 304 when the winding 304 tightens. At the same time, the terminal sends a notification to the workers so that the workers can hoist the cleaned steel pipe assembly away to complete the unloading-storage-feeding process.

8. A driving method for a material conveying and storage device for cleaned steel pipes as described in claim 7, characterized in that, The driving method includes: Multiple feeding and storage mechanisms move simultaneously and synchronously. The feeding module pushes the steel pipe (1) to be fed onto the feeding rack (2). The steel pipe (1) to be fed rolls from the high end to the low end of the feeding rack (2). When it passes the feeding sensing component (209), the feeding sensing component (209) counts. After the steel pipe (1) reaches the low end, it is intercepted by the feeding baffle (210). Then the feeding baffle (210) is lowered so that the steel pipe (1) to be fed enters the pneumatic storage rack (3). According to the number of steel pipes (1) to be fed fed as fed by the feeding sensing component (209), when the number of steel pipes (1) to be fed fed reaches the preset number, the initially relaxed winding belt (304) of the pneumatic storage rack (3) is tightened to support the steel pipe (1) to be fed.

9. The driving method for a material feeding, conveying, and storage device for cleaned steel pipes according to claim 8, characterized in that, The driving method is specifically as follows: Step 1: The output end of the hydraulic cylinder (205) extends and drives the two unloading flaps (202) to swing simultaneously, pushing the multiple steel pipes (1) to be unloaded on the two unloading flaps (202) into the unloading frame (201). The multiple steel pipes (1) to be unloaded roll from the high end to the low end of the unloading frame (201), and each steel pipe (1) to be unloaded collides with the touch lever (214), causing the touch lever (214) to swing, thereby driving the trigger end of the proximity sensing bolt (217) on the touch lever (214) away from the sensing end of the proximity switch (216), thus obtaining the number of steel pipes (1) to be unloaded that have rolled over. After the steel pipe (1) to be unloaded rolls over, the touch lever (214) is brought back to the initial position by the tension spring (219) to prepare for the next steel pipe (1) to be unloaded to roll over. Step 2: When the steel pipe (1) to be unloaded moves to the low end, it is stopped by the unloading baffle (210). The unloading baffle (210) is driven to descend by the unloading baffle cylinder (212), so that the steel pipe (1) to be unloaded continues to move into the U-shaped groove of the storage frame (301) of the pneumatic storage rack (3). When the number of steel pipes (1) to be unloaded that have passed through the unloading sensing component (209) reaches the preset number, the winding tensioning cylinder (305) pulls the winding belt (304) to tighten and support the steel pipe (1) to be unloaded between the second pin and the third pin.
