Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe production technology, and in particular to a safe transfer device for steel pipe production. Background Technology
[0002] In the modern steel pipe manufacturing industry, the production process involves multiple stages, from raw material processing to final packaging of finished products. Each stage has a significant impact on production efficiency and product quality. Among them, the transfer stage of steel pipes is particularly critical, because steel pipes need to be frequently transferred between different processes during production, such as from the rolling mill to the cooling zone, and then to the inspection and packaging area.
[0003] A search revealed a safe steel pipe production transfer device (publication number CN221214065U) comprising two bases and two connecting rods. The two bases are connected by the two connecting rods. Each base has two fixed structures mounted on its top. One of the fixed structures includes two positioning columns, two sliding grooves, several sliding sleeves, several limiting blocks, several arc-shaped grooves, several fixing bolts, and two connecting components. This utility model relates to the field of steel pipe production technology. The advantages of this invention are: the use of two fixed structures allows adjustment of the distance between the two bases according to the length of the steel pipe to be transferred. The steel pipe can then be placed on the top of several arc-shaped grooves, and the limiting blocks can be moved along the positioning columns to clamp and fix both ends of the steel pipe. The operator can then transfer the fixed steel pipe. This device is easy to operate and has a wide range of applications.
[0004] Based on the aforementioned patent, the fixed structure allows for adjustment of the distance between the two bases according to the length of the steel pipe to be transferred during operation. The steel pipe can then be placed on the top of several arc-shaped grooves, and the limiting block can be moved along the positioning column to clamp and fix both ends of several steel pipes. The operator can then transfer these fixed steel pipes. This method is convenient to operate and has a wide range of applications. However, when using two upper and lower clamping components for fixing during pipe transfer, the arc-shaped grooves of the fixing components clamp and fix the pipe. When the pipe diameter exceeds the curvature of the arc-shaped groove, the fixing force of the arc-shaped groove on the pipe decreases, affecting the fixing effect of the device during transfer. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a safe steel pipe production transfer device. It facilitates the shrinking and fitting of the fixing claws according to the pipe diameter to achieve a fixing effect, and lifts and transfers the pipe to be installed, reducing the burden on operators.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A safe steel pipe production transfer device includes a clamping platform. A connecting shell is fixedly connected to the left and right sides of the top of the clamping platform. A moving block is slidably connected to the inner wall of the connecting shell through a transmission assembly. A traction plate is rotatably connected to both the front and rear ends of the moving block. A fixed claw is connected to the opposite end of the traction plate through the clamping assembly.
[0008] A mobile platform, with a mounting frame fixedly connected to its top end, and the outer wall of the clamping platform fixedly connected to the inner wall of the mounting frame. A traction rope is connected to the top end of the mounting frame via a retractable assembly, and the other end of the traction rope is fixedly connected to a mobile frame. The mobile frame is connected to a lifting claw via a lifting assembly.
[0009] Furthermore, the transmission assembly includes several transmission screws rotatably connected to the right end of the mounting frame. Both ends of the outer wall of the transmission screws are threaded with extrusion blocks, and the bottom end of the extrusion blocks is slidably connected to the bottom end of the inner wall of the connecting shell.
[0010] Furthermore, the clamping assembly includes connecting plates rotatably connected to the opposite ends of the traction plate, and the opposite ends of the connecting plates are respectively rotatably connected to the opposite ends of the fixing claws.
[0011] Furthermore, a fixed shell is slidably connected to the outer wall of the movable block, the bottom end of the fixed shell is fixedly connected to the inner wall of the connecting shell, and the bottom side of the opposite end of the connecting plate is rotatably connected to the front and rear sides of the inner wall of the fixed shell.
[0012] Furthermore, the retraction assembly includes an electric take-up reel fixedly connected to the top of the mounting frame, and the outer wall of the traction rope is fitted onto the retraction end of the electric take-up reel.
[0013] Furthermore, the hoisting assembly includes a linkage plate rotatably connected to both the left and right sides of the top of the movable frame, and a retractable plate rotatably connected to the opposite end of each linkage plate. The inner wall of the opposite end of the retractable plate is rotatably connected to the outer walls of the left and right ends of the support frame, and the hoisting claw is fixedly connected to the opposite end of the outer wall of the retractable plate.
[0014] Furthermore, fixed frames are slidably connected to the left and right sides of the bottom of the movable frame. The bottom ends of the fixed frames are respectively fixedly connected to the left and right sides of the outer wall of the support frame. A deflection tube is fixedly connected to the bottom of the movable frame. A fixed pin is sleeved on the inner wall of the deflection tube. A locking pin is fixedly connected to the bottom end of the fixed pin.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, the extrusion block is displaced by rotating the transmission screw, and the extrusion block extrudes the moving block, causing the moving block to move along the inside of the fixed shell. The moving block drives the traction plate to deflect the fixing claw, so that the fixing claw clamps the pipe. This allows the fixing claw to shrink and fit according to the pipe diameter to achieve a fixing effect, ensuring that it can be effectively fixed under different diameters.
[0017] 2. In this utility model, the movable frame slides down along the fixed frame, causing the locking pin connected to the fixed pin in the deflection tube to fit against the support frame. After being squeezed, the locking pin deflects along the deflection tube, and the fixed pin drives the locking pin to lock onto the support frame, thus limiting the position of the movable frame. The linkage plate drives the retraction plate to retract the lifting claw, clamping the pipe. Then, the electric winding wheel is started to wind up the traction rope, which facilitates the lifting and transportation of the device, reduces the burden on the operator, and improves the convenience and efficiency of operation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figures 1-3 This utility model provides an embodiment of a safe steel pipe production transfer device, including a clamping platform 3. Connecting shells 5 are fixedly connected to the left and right sides of the top of the clamping platform 3. A plurality of transmission screws 4 are rotatably connected to the right end of a mounting frame 2. Extrusion blocks 12 are threadedly connected to the left and right ends of the outer walls of the transmission screws 4. The bottom ends of the extrusion blocks 12 are slidably connected to the bottom end of the inner wall of the connecting shells 5. Traction plates 15 are rotatably connected to the front and rear ends of a moving block 14. (Refer to...) Figure 4 The connecting plate 16 is rotatably connected to the opposite end of the traction plate 15. The opposite end of the connecting plate 16 is rotatably connected to the opposite end of the fixed claw 11. The outer wall of the moving block 14 is slidably connected to the fixed shell 13. The bottom end of the fixed shell 13 is fixedly connected to the inner wall of the connecting shell 5. The bottom side of the opposite end of the connecting plate 16 is rotatably connected to the front and rear sides of the inner wall of the fixed shell 13.
[0028] Specifically: After the pipe is installed at the fixed claw 11, the compression block 12 can be displaced by rotating the transmission screw 4. During the movement, the compression block 12 will compress the moving block 14. Due to the low coefficient of friction and high fit between the compression block 12 and the moving block 14, this compression action causes the moving block 14 to move precisely along the inside of the fixed shell 13. The displacement of the moving block 14 drives the traction plate 15, thereby causing the fixed claw 11 to deflect. The deflection action of the fixed claw 11 enables the fixed claw 11 to clamp the pipe, ensuring the stability and safety of the pipe during transportation. In addition, the fixed claw 11 can automatically shrink and fit according to the diameter of the pipe, further enhancing the fixing effect, so that the pipe can be effectively fixed under different diameters. This design not only improves the adaptability of the device, but also significantly improves the safety and reliability of operation.
[0029] Reference Figure 5 and Figure 6A mobile platform 1 is fixedly connected to a mounting frame 2 at its top. A clamping platform 3 is fixedly connected to the inner wall of the mounting frame 2 on its outer wall. An electric winding wheel 6 is fixedly connected to the top of the mounting frame 2. A traction rope 7 is fitted onto the retracting end of the electric winding wheel 6 on its outer wall. A mobile frame 17 is fixedly connected to the other end of the traction rope 7. A linkage plate 21 is rotatably connected to both the left and right sides of the top of the mobile frame 17. A retracting plate 22 is rotatably connected to the opposite end of the linkage plate 21. The inner wall of the opposite end of the retracting plate 22 is rotatably connected to the outer walls of the left and right ends of the support frame 8. A lifting claw 10 is fixedly connected to the opposite end of the outer wall of the retracting plate 22 on its opposite end. A fixed frame 9 is slidably connected to both the left and right ends of the mobile frame 17. The bottom ends of the fixed frames 9 are fixedly connected to the left and right sides of the outer wall of the support frame 8. A deflection tube 18 is fixedly connected to the bottom end of the mobile frame 17. A fixed pin 19 is fitted onto the inner wall of the deflection tube 18. A locking pin 20 is fixedly connected to the bottom end of the fixed pin 19.
[0030] Specifically: When the electric winding reel 6 is activated for lowering, the traction rope 7 gradually extends, allowing the support frame 8 to fit against the pipe to be installed. After the traction rope 7 extends, the moving frame 17 slides down along the fixed frame 9 under the action of gravity. During the descent of the moving frame 17, the corrugated groove on the inner side of the deflection tube 18 interacts with the locking post 20 connected to the fixed pin post 19. After being squeezed by the support frame 8, the locking post 20 deflects 90 degrees along the corrugated groove in the deflection tube 18, thereby causing the fixed pin post 19 to drive the locking post 20 to lock at the support frame 8, reaching the position of the moving frame 17. The limiting effect ensures that the moving frame 17 stays in the correct position and will not shift due to external interference. Then, the linkage plate 21 drives the retraction plate 22 to retract, causing the lifting claw 10 to retract and tightly clamp the pipe. The clamping action of the lifting claw 10 ensures the stability and safety of the pipe during the lifting process, preventing the pipe from slipping or shaking. Finally, the electric winding wheel 6 is started again to wind up the traction rope 7, so that the device can smoothly lift and transfer the pipe. Through this series of coordinated actions, the device not only improves the efficiency of the transfer process, but also significantly enhances the safety of operation.
[0031] Working principle: When the electric winding reel 6 is lowered, the traction rope 7 extends, allowing the support frame 8 to fit against the pipe to be installed. With the traction rope 7 extended, the moving frame 17, under the influence of gravity, slides down along the fixed frame 9. This causes the locking pin 20 connected to the fixed pin 19 inside the deflection tube 18 to fit against the support frame 8. When the locking pin 20 is compressed, it deflects along the deflection tube 18, causing the fixed pin 19 to engage the locking pin 20 at the support frame 8, thus limiting the position of the moving frame 17. This, in turn, causes the linkage plate 21 to drive the retraction plate 22, allowing the lifting claw 10 to advance... The lifting claw 10 clamps the pipe by contracting, and then the electric winding wheel 6 is started to wind up the traction rope 7, which facilitates the lifting work of the device during transportation. After the pipe is installed at the fixed claw 11, the transmission screw 4 is rotated to displace the extrusion block 12, so that the extrusion block 12 extrudes the moving block 14, causing the moving block 14 to move along the fixed shell 13. This causes the moving block 14 to drive the traction plate 15 to deflect the fixed claw 11, so that the fixed claw 11 clamps the pipe. This allows the fixed claw 11 to contract and fit according to the pipe diameter to achieve a fixing effect.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
