Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe turning equipment, in particular to a rotary steel pipe turning device. Background Technique

[0002] Steel pipes are a common type of metal pipe, mainly used for conveying fluids, supporting structures, etc. When steel pipes are produced, they will also be drawn according to actual production requirements to obtain the required dimensions and shapes, or cut to obtain steel pipes of the required length or cut into small segments of different shapes;

[0003] After the above-mentioned steel pipe processing is completed, the steel pipe will be pushed out from the processing position, and a conveying mechanism will be used to convey the processed steel pipe towards the storage rack. When the existing steel pipe is unloaded from the conveying mechanism, a single-arm pneumatic device composed of a cylinder and a push rod is generally used. Therefore, when the steel pipe on the conveying mechanism is unloaded by this type of single-arm pneumatic device, the single-arm pneumatic mechanism relies on pneumatic control technology to realize the turning and unloading action. If there is a deviation in the pushing process of the pneumatic control, problems such as uncoordinated actions, slow speed, and insufficient force will occur, thus affecting work efficiency and equipment stability. At the same time, the single-arm pneumatic mechanism usually consists of multiple mechanical components, with a relatively complex structure, and is prone to mechanical failures such as jamming and wear. In addition, the complex mechanical structure also increases the difficulty of maintenance and repair, resulting in a long troubleshooting time and low efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rotary steel pipe turning device, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A rotary steel pipe turning device includes a supporting table and multiple brackets. A main control box is fixedly installed at the front end of the supporting table. A speed reducer is fixedly installed on the supporting table. The input end of the speed reducer is fixedly installed with a motor, and the motor is electrically connected to the main control board in the main control box through a cable. A rotating shaft is rotatably installed between multiple brackets. One end of the rotating shaft is fixedly connected to the output end of the speed reducer through a coupling. A turning mechanism is arranged on the rotating shaft on one side of the bracket. The turning mechanism includes a control ring and a mounting seat. The control ring is fixedly installed on one side of the bracket. The mounting seat is fixedly installed on the rotating shaft. Two turning rods are fixedly installed on the outside of the mounting seat. Turning hooks are fixedly installed at the ends of the two turning rods away from the mounting seat. A limiting rod is movably installed in the turning hook.

[0007] Preferably, a flange is fixedly installed on the outer side of the control ring. The flange is arc-shaped and is located above the outer side of the control ring. A plurality of connecting rods are fixedly installed on one side of the control ring. One end of the connecting rod is fixedly installed with a connecting plate, and the connecting plate is fixedly installed on one side of the corresponding bracket through bolts. By arranging the control ring on one side of the bracket and an arc-shaped flange on the outer side of the control ring, the movement of the limiting rod can be controlled by using the height difference between the outer contours of the control ring and the flange.

[0008] Preferably, a chute A is opened on one side of the turning rod relative to the control ring. A chute B is opened on one side inside the chute A, and a threaded hole is opened on one side inside the chute B. A connecting screw is threadedly connected in the threaded hole. The turning rod is fixedly installed on the outer side of the mounting seat, so that when the mounting seat rotates following the rotating shaft, the chute A can rotate on the outer sides of the control ring and the flange.

[0009] Preferably, a fixed seat is further fixedly installed at one end of the turning rod away from the mounting seat. The upper end of the turning hook is fixedly installed on the fixed seat through bolts. An insertion through groove is opened inside the turning hook. By arranging the turning hook, when the rotating shaft drives the mounting seat and the turning rod to rotate, the steel pipe can be hooked.

[0010] Preferably, a top push rod is fixedly installed at one end of the limiting rod. A limiting groove is opened on one side of the top push rod. The top push rod is inserted and installed in the chute B, and one end of the limiting rod is inserted and installed in the insertion through groove, and the limiting groove is inserted and installed at one end of the connecting screw.

[0011] Preferably, a compression spring is further sleeved on the connecting screw between the top push rod and one side inside the chute B. When the turning rod rotates with the mounting seat on the outer sides of the control ring and the flange, the reciprocating movement of the top push rod can be realized by the height difference between the control ring and the flange in cooperation with the compression spring, so that after the turning hook hooks the steel pipe, the limiting rod is used to prevent the steel pipe from falling off from the turning hook.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] For a rotary steel pipe turning device of the utility model, through the settings of a speed reducer, a motor and a rotating shaft, and in cooperation with a photoelectric sensor, the steel pipes conveyed by the conveying mechanism can be inductively identified, and the mounting seat, the turning rod and the turning hook are rotated through the rotating shaft, so that the steel pipes are turned from the conveying mechanism by the rotating turning hook and the steel pipes are discharged to a transfer device or a storage rack. Moreover, the cooperation of the control ring, the flange, the limiting rod and the top push rod can play a role in preventing the steel pipes in the turning hook from falling off, improving the turning and discharging efficiency of the steel pipes and reducing the failure rate of the whole mechanism.

Specific embodiments

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] As Figures 1 - 4 shown, a rotary steel pipe material turning device provided by the present utility model includes a supporting table 1 and a plurality of brackets 2. A main control box 26 is fixedly installed at the front end of the supporting table 1. A reducer 3 is fixedly installed on the supporting table 1. The input end of the reducer 3 is fixedly installed with a motor 4, and the motor 4 is electrically connected to the main control board in the main control box 26 through a cable. A rotating shaft 5 is rotatably installed between the plurality of brackets 2. One end of the rotating shaft 5 is fixedly connected to the output end of the reducer 3 through a coupling 6. A material turning mechanism 7 is arranged on the rotating shaft 5 on one side of the bracket 2. The material turning mechanism 7 includes a control ring 8 and a mounting seat 9. The control ring 8 is fixedly installed on one side of the bracket 2. The mounting seat 9 is fixedly installed on the rotating shaft 5. Two material turning rods 10 are fixedly installed on the outer side of the mounting seat 9. Material turning hooks 11 are respectively fixedly installed at the ends of the two material turning rods 10 away from the mounting seat 9. A limiting rod 12 is movably installed in the material turning hook 11.

[0021] As Figures 2 - 3 shown, a flange 13 is fixedly installed on the outer side of the control ring 8. The flange 13 is arc-shaped and is located above the outer side of the control ring 8. A plurality of connecting rods 14 are fixedly installed on one side of the control ring 8. One end of the connecting rod 14 is fixedly installed with a connecting plate 15. The connecting plate 15 is fixedly installed on one side of the corresponding bracket 2 through bolts. By arranging the control ring 8 on one side of the bracket 2 and arranging an arc-shaped flange 13 on the outer side of the control ring 8, the movement of the limiting rod 12 can be controlled by using the height difference between the outer contour of the control ring 8 and the flange 13;

[0022] As Figure 2 , Figure 4 shown, a chute A17 is provided on one side of the material turning rod 10 relative to the control ring 8. A chute B18 is provided on one side within the chute A17. A threaded hole 19 is provided on one side within the chute B18. A connecting screw 23 is threadedly connected within the threaded hole 19. The material turning rod 10 is fixedly installed on the outside of the mounting seat 9. When the mounting seat 9 rotates following the rotating shaft 5, the chute A17 can rotate on the outside of the control ring 8 and the flange 13. One end of the material turning rod 10 away from the mounting seat 9 is also fixedly installed with a fixed seat 16. The upper end of the material turning hook 11 is fixedly installed on the fixed seat 16 by bolts. An insertion through slot 20 is provided within the material turning hook 11. Through the provision of the material turning hook 11, when the rotating shaft 5 drives the mounting seat 9 and the material turning rod 10 to rotate, the steel pipe can be hooked;

[0023] As Figure 4 shown, a top push rod 21 is fixedly installed at one end of the limiting rod 12. A limiting slot 22 is provided on one side of the top push rod 21. The top push rod 21 is inserted and installed within the chute B18. One end of the limiting rod 12 is inserted and installed within the insertion through slot 20. The limiting slot 22 is inserted and installed at one end of the connecting screw 23. A compression spring 24 is also sleeved on the connecting screw 23 between the top push rod 21 and one side within the chute B18. When the material turning rod 10 rotates on the outside of the control ring 8 and the flange 13 following the mounting seat 9, the reciprocating movement of the top push rod 21 can be achieved by the height difference between the control ring 8 and the flange 13 in cooperation with the compression spring 24, so that after the material turning hook 11 hooks the steel pipe, the limiting rod 12 is used to prevent the steel pipe from falling off from within the material turning hook 11.

[0024] It should be noted that the present utility model is a rotary steel pipe turning device. When turning and discharging the steel pipe, the photoelectric sensor 25 can be used to detect and sense the conveyed steel pipe. Then, the motor 4 drives the rotating shaft 5 to rotate between multiple brackets 2 through the speed reducer 3. The rotating shaft 5 drives multiple mounting seats 9 to rotate synchronously, and the mounting seats 9 drive the two turning rods 10 on the outside to rotate synchronously. The turning rods 10 on the same side of the multiple mounting seats 9 use the turning hooks 11 at one end to hook up the steel pipe on the conveying mechanism from bottom to top and rotate around the rotating shaft 5 following the turning rods 10. When the turning rod 10 rotates a certain angle following the mounting seat 9, the chute A17 on one side of the turning rod 10 rotates outside the control ring 8, and after the chute A17 moves to the position of the flange 13 outside the control ring 8, the top push rod 21 is pushed to one side in the chute B18 through the flange 13, so that the limit groove 22 at the other end of the top push rod 21 moves at one end of the connecting screw 23 and compresses the compression spring 24 towards one side in the chute B18. At the same time, the top push rod 21 drives the limit rod 12 to move to one side, and one end of the limit rod 12 passes through the insertion through slot 20 and is placed above the steel pipe, so as to prevent the steel pipe from detaching from the turning hook 11 when the turning hook 11 flips. Then, when the turning rod 10 drives the steel pipe to flip 180 degrees through the turning hook 11, the chute A17 rotates to the other side of the control ring 8 again, and with the acting force of the compression spring 24, the top push rod 21 is pushed towards the control ring 8, so that the top push rod 21 drives the limit rod 12 to move towards the mounting seat 9, and the limit of the steel pipe by the limit rod 12 can be released, enabling the steel pipe to detach from the turning hook 11, thus realizing the turning and discharging of the steel pipe in an electric rotation mode and improving the efficiency of turning and discharging.
