Description

Technical Field

[0001] This invention belongs to the field of steel pipe processing technology, and in particular relates to an automatic steel pipe turning and receiving device. Background Technology

[0002] In the steel pipe production process, to achieve automated production, a turning mechanism is installed between the worktable and the roller conveyor. The function of the turning mechanism is to facilitate the transition and connection of steel pipes between different pieces of equipment, enabling rapid and automated production. Currently, the most commonly used mechanisms are the flat-dragging turning mechanism or the direct turning hook mechanism. The flat-dragging mechanism can turn materials stably, but the equipment itself is heavy, requires a large rotation space, and has a high investment cost. The direct turning hook mechanism has a simple structure, but the turning process is rough, with high impact force, which can easily cause equipment damage and steel pipe quality problems. The key is to find a solution that simultaneously satisfies the requirements of simple and lightweight structure, does not damage the equipment it serves, and minimizes the impact on steel pipe quality.

[0003] Generally, a fixed baffle is installed to prevent the steel pipe from falling off the roller conveyor, and the impact force of the falling steel pipe is borne by the receiving roller conveyor. This structural design has the following problems: ① The impact force of the steel pipe on the roller conveyor is large, leading to loosening of the roller conveyor bearing seat bolts and bearing seat breakage, reducing bearing life; ② At the moment the steel pipe falls onto the roller conveyor, it experiences not only a downward impact force but also an outward rolling force, resulting in a significant impact force on the roller conveyor itself upon impact with the baffle; ③ The entire impact process can damage the steel pipe.

[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1-7 As shown, an automatic steel pipe turning and receiving device includes a fixed frame 1, a roller conveyor mechanism 2, and a turning mechanism 3. The roller conveyor mechanism 2 is mounted on the fixed frame and is used to transport steel pipes; the turning mechanism 3 is mounted on the fixed frame and is used to turn the steel pipes onto the roller conveyor mechanism.

[0031] Specifically, the material-turning mechanism includes a first support rod 31, a turning arm 32, a second support rod 33, a receiving arm 34, a baffle plate 35, a first driving component 36, and a second driving component 37. The first support rod 31 is fixed to a fixed frame; the turning arm 32 is rotatably connected to the first support rod; the second support rod 33 is fixed to the fixed frame and is correspondingly arranged with the first support rod; the receiving arm 34 is rotatably connected to the end of the second support rod; the baffle plate 35 is curved in an arc and is fixed to the end of the receiving arm; the first driving component 36 is a hydraulic push rod, one end of which is hinged to the fixed frame, and the other end is rotatably connected to a drive shaft 361. The turning arm 32 has a sliding groove 321 for the drive shaft to slide into, and the first driving component 36... The extension and retraction of the first drive component can drive the tilting arm to rotate relative to the first support rod. The second drive component 37 is a hydraulic push rod, one end of which is hinged to the fixed frame and the other end is connected to the receiving arm. Its connection method is the same as that of the first drive component and the tilting arm. The extension and retraction of the second drive component can drive the receiving arm to rotate relative to the second support rod. When tilting, the receiving arm is first rotated to a horizontal position, and then the tilting arm is pushed to flip by the first drive component, thereby taking out the steel pipe from the material rack. The steel pipe will roll along the tilting arm to the receiving arm and then hit the baffle plate to stop, thereby absorbing the impact of the rolling steel pipe to avoid damaging the roller conveyor mechanism. Then, the receiving arm is rotated by the second drive component to place the steel pipe on the roller conveyor mechanism for conveying.

[0032] As a preferred embodiment, the baffle plate 35 is equipped with a buffer assembly, which includes a fixed post 351, a first elastic telescopic rod 352, a first elastic element 353, a buffer plate 354, a second mounting hole 355, a fifth elastic element 356, and a buffer block 357. The fixed post 351 is uniformly fixed on the baffle plate; the first elastic telescopic rod 352 is a metal first elastic telescopic rod, which is uniformly arranged on the outer wall of the fixed post, and one end of the first elastic telescopic rod is hinged to the fixed post; the buffer plate 354 is hinged to the end of the first elastic telescopic rod; the first elastic element 353 is a spring, which is sleeved on the first elastic telescopic rod, and its two ends are respectively fixed to the ends of the first elastic telescopic rod. Thus, the impact force of the rolling steel pipe can be absorbed by the first elastic telescopic rod and the first elastic element, preventing the steel pipe from directly hitting the baffle plate; the second mounting hole 355 is opened on the fixed post; the fifth elastic element 356 is a spring, and one end of it is fixed in the second mounting hole; the buffer block 357 is fixed to the end of the fifth elastic element to prevent the end of the fixed post from colliding with the buffer plate.

[0033] Specifically, the roller conveyor mechanism includes a first fixed plate 21, a second fixed plate 22, a rotating shaft 23, rollers 24, transmission wheels 25, drive wheels 26, a connecting belt 27, a third drive component 28, and a connecting assembly for connecting the rotating shaft and the first fixed plate. The first fixed plate 21 is evenly fixed on the fixed frame; the second fixed plate 22 has third fixed plates 221 fixed on both sides, and the fixed frame is screwed with second bolts 222. The third fixed plate 221 is provided with a limiting groove 223 that cooperates with the second bolts; the rotating shaft 23 is connected to the first fixed plate through the connecting assembly; the rollers 24 are fixed on the rotating shaft; the transmission wheels 25 are fixed on the end of the rotating shaft; the connecting belt 27 is sleeved on the drive wheels and transmission wheels; the third drive component 28 is a motor, which is fixed on the fixed frame; the drive wheels 26 are fixed on the output shaft of the third drive component, so the third drive component can drive the rotating shaft to rotate, and then the rollers to rotate, thereby driving the steel pipe to move on the rollers.

[0034] As a preferred embodiment, the connecting assembly includes a slide groove 291, a guide rod 292, a slider 293, a bearing 294, a second elastic element 295, a second elastic telescopic rod 296, a tensioning shaft 297, and a tensioning wheel 298. The slide groove 291 is formed on the first fixed plate; both ends of the guide rod 292 are fixed to the inner wall of the slide groove; the slider 293 is disposed on the guide rod and can slide up and down relative to the guide rod, and the slider has a hole that mates with the bearing; the inner wall of the bearing 294 is fixed to the rotating shaft, and the outer wall is fixed in the hole of the slider; the second fixed plate 22 also has a slide groove, and the slider, guide rod, and shaft are also connected. The bearing is connected to the rotating shaft, but the bearing in the second fixed plate can move relative to the rotating shaft; the second elastic element 295 is a spring, which is sleeved on the guide rod and its two ends are respectively fixed to the inner wall of the slide groove. The impact force of the steel pipe falling on the roller can be absorbed by the second elastic element, reducing the impact on the rotating shaft, bearing and the first fixed plate; the second elastic telescopic rod 296 is fixed on the fixed frame; the tensioning shaft 297 is fixed on the end of the second elastic telescopic rod; the tensioning wheel 298 is rotatably connected to the tensioning shaft, and it fits against the connecting belt to ensure the connection between the connecting belt and the transmission wheel and the drive wheel during the up and down movement of the transmission wheel.

The mounting plate 201 is detachably fixed to both ends of the roller via the connecting component. The mounting plate is made of an elastic material with a higher elastic modulus than the rubber sleeve. The rubber sleeve 202 is fitted over the roller, with both ends fixed to the mounting plate, and its shape is the same as that of the roller. The air nozzle is fixed to the mounting plate and is used to inject gas into the rubber sleeve. The deformation element 204 has a cavity 2041 and an air inlet 2042, and is made of rubber corrugated pipe. It is fixed to the mounting plate and injects inert gas into the rubber sleeve through the air nozzle. The inner wall of the rubber sleeve and the outer wall of the roller form a... A buffer chamber is formed. When the steel pipe falls onto the roller, it is squeezed into the buffer chamber to form a buffer. After the buffer chamber deforms, the squeezed gas enters the cavity inside the deforming part. After the steel pipe is transported, the deforming part will restore the squeezed air and return to the buffer chamber, which is convenient for buffering the next steel pipe falling. The guide sleeve 205 is sleeved on the outside of the deforming part and is fixed to the mounting plate. The pressure plate 206 can slide relative to the inner wall of the guide sleeve. One end of the pressure rod 207 is fixed to the pressure plate, and the other end is fixed to the limit protrusion 2071. The fourth elastic element 208 is a spring, which is sleeved on the pressure rod. One end of the spring is fixed to the limit protrusion, and the other end is fixed to the third support rod. The third support rod 209 is fixed to the connecting part. The pressure rod can slide relative to the third support rod. By pulling the pressure rod through the fourth elastic element, the pressure plate can be driven to squeeze the deforming part, which is convenient for the gas in the deforming part to be quickly sent into the buffer chamber.

[0036] As a preferred embodiment, the connecting components include a locking plate 241, a first bolt 242, a retaining plate 243, a threaded hole, a first mounting hole 244, a third elastic element 245, a push rod 246, and a ball bearing 247.

When the rubber sleeve needs to be replaced, the second bolt is unscrewed, the second fixing plate is moved, and the rotating shaft is moved from the second fixing plate. The bearing inside the fixed plate is removed, and then the first bolt is unscrewed. The locking plate on one side is then removed, and the rubber sleeve and mounting plate can be removed from the roller for easy replacement of the rubber sleeve. The first mounting hole 244 is opened on the inner wall of the circular hole. The third elastic element 245 is a spring, one end of which is fixed in the first mounting hole. The push rod 246 is fixed on the end of the third elastic element and can slide relative to the inner wall of the first mounting hole. The ball 247 is rotatably connected to the end of the push rod. The outer wall of the rotating shaft is provided with a positioning groove that mates with the ball. When the ball is aligned with the positioning groove, the first bolt is aligned with the threaded hole, making it easy to tighten the first bolt.
