Description

Technical Field

[0001] This utility model belongs to the technical field of steel pipe conveying devices, specifically relating to a steel pipe conveying mechanism that transports steel pipes one by one in a steel pipe conveying process. Background Technology

[0002] In a steelmaking plant, the initial form of a steel pipe is a steel billet. A mandrel is used to pass through the center of the billet to refine it into a steel pipe. Before this, the billet needs to be transported to a rotary kiln and heated to a high temperature. When transporting the billet to the rotary kiln for heating, the billets need to be fed in one by one. Therefore, it is necessary to transport the billets individually. Existing steel pipe conveying devices place multiple billets directly on the conveying rollers for transport. There is no device for transporting individual steel pipes, so it is impossible to transport individual steel pipes.

[0003] Therefore, the technical problem to be solved by this utility model is: how to realize the transportation of a single steel pipe. Utility Model Content

[0004] To address the technical problem of how to transport single steel pipes, this utility model provides a steel pipe transport mechanism that transports steel pipes one by one.

[0005] The specific plan is as follows: A steel pipe conveying mechanism for conveying steel pipes one by one includes a frame with a circular hole. A rotating shaft a is inserted into the circular hole, and the frame is rotatably connected to the rotating shaft a, allowing the rotating shaft a to rotate within the circular hole. The rotating shaft a is fixedly connected to a swing arm and a working ring, and the working ring is connected to a drive device, which drives the rotating shaft a, the swing arm, and the working ring to rotate together. The swing arm includes an arc-shaped edge tangent to a conveying roller, and the upper part of the arc-shaped edge has a groove for accommodating a single steel pipe. The center of the circle containing the arc-shaped edge coincides with the rotating shaft a, allowing the arc-shaped edge to rotate about the rotating shaft a.

[0006] The upper part of the arc-shaped edge is connected to the groove through the first short side, and the height of the first short side is either flush with or lower than the upper surface of the conveying roller, so that the steel pipe on the conveying roller can roll into the groove.

[0007] The frame is hinged to the cylinder body end of the hydraulic cylinder, the piston end of the hydraulic cylinder is hinged to the connecting block, and the connecting block is fixed to the working ring.

[0008] The connecting block is a counterweight, which is distributed on both sides of the pivot a along with the swing arm.

[0009] The beneficial effects of this utility model are as follows: This utility model provides a steel pipe conveying mechanism for conveying steel pipes one by one. It features a swing arm with an arc-shaped edge, and a groove at the upper part of the arc-shaped edge to accommodate a single steel pipe. The arc-shaped edge is connected to one side of the groove via a first short side, and the height of the first short side is either flush with or below the upper surface of the conveying roller, allowing the steel pipe on the conveying roller to roll into the groove. A driving device drives the swing arm to rotate until the other side of the groove is flush with the upper surface of the conveying channel for the next process, at which point the rotation stops. The single steel pipe in the groove then falls into the conveying channel for the next process. Throughout the rotation of the swing arm, the arc-shaped edge continuously blocks the next steel pipe, thus achieving the conveying of single steel pipes. The device has a simple structure and is easy to use. Attached Figure Description

[0011] Figure 2 This is a schematic diagram of a conveyor system transporting steel pipes.

[0012] Figure 3 This is a schematic diagram of the drive mechanism. Detailed Implementation

[0013] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the implementation of this utility model, not all of it. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0014] like Figure 1 and Figure 2 As shown, this utility model provides a steel pipe conveying mechanism for conveying steel pipes one by one, including a frame 1, which is fixed on the ground. The frame 1 is provided with a circular hole, and a rotating shaft a is inserted into the circular hole. The frame 1 and the rotating shaft a are rotatably connected, so that the rotating shaft a can rotate in the circular hole.

[0015] The rotating shaft a is fixedly connected to the swing arm 2 and the working ring 3 respectively. The working ring 3 is connected to the driving device, which can drive the rotating shaft a, the swing arm 2 and the working ring 3 to rotate together.

[0016] The swing arm 2 includes an arc-shaped edge 21, which is tangent to the conveying roller 8. The upper part of the arc-shaped edge 21 is provided with a groove 22 that can accommodate a single steel pipe, so that the steel pipe 7 transported from the conveying roller 8 can roll into the groove 22. The other side of the swing arm 2 is provided with a conveying channel 6 for the next process. The swing arm 2 can be rotated so that the side of the groove 22 away from the conveying roller 8 is flush with the upper surface of the conveying channel 6 for the next process, so that the steel pipe 7 in the groove 22 can roll onto the conveying channel 6 for the next process.

[0017] The center of the circle containing the arc-shaped edge 21 coincides with the rotating shaft a, allowing the arc-shaped edge 21 to rotate around the rotating shaft a. Since the arc-shaped edge 21 is tangent to the edge of the conveying roller 8, during the rotation of the arc-shaped edge 21 around the rotating shaft a, the arc-shaped edge 21 always remains tangent to the edge of the conveying roller 8, thereby blocking the transport of the next steel pipe 7 and realizing the transport of a single steel pipe.

[0018] In this embodiment, the frame 1 can be fixed to the ground with bolts or other fixing methods. The frame 1 is rotatably connected to the rotating shaft a, which can rotate relative to the frame 1. The rotating shaft a is fixedly connected to the swing arm 2 and the working ring 3 respectively, and the frame 1 is located between the swing arm 2 and the working ring 3 to increase stability.

[0019] like Figure 1 As shown, the upper part of the arc-shaped edge 21 is connected to the groove 22 through the first short side 23, and the height of the first short side 23 is flush with or lower than the upper surface of the conveying roller 8, so that the steel pipe 7 on the conveying roller 8 can roll into the groove 22.

[0020] like Figure 3 The frame 1 is hinged to the cylinder body end of the hydraulic cylinder 5, and the piston end 51 of the hydraulic cylinder 5 is hinged to the connecting block 31. The connecting block 31 is fixed to the working ring 3.

[0021] The connecting block 31 is a counterweight block, which is distributed on both sides of the rotating shaft a along with the swing arm 2, so that the center of gravity of the entire device is located at the rotating shaft a, and the swing arm 2 and the working ring 3 can be relatively balanced. With this balanced setting, only a small force needs to be applied to the working ring 3 by the oil cylinder 5 to make the working ring 3 rotate, thereby driving the swing arm 2 to rotate.

[0022] like Figure 1As shown, in this embodiment, the initial state is used as an example for explanation. The swing arm 2 is generally shaped like a wing. The swing arm 2 includes a vertical arc-shaped side 21. The upper part of the arc-shaped side 21 is connected to one side of the groove 22 through a first short side 23. The other side of the groove 22 is connected to one side of the inclined side 25 through a second short side 24. The other side of the inclined side 25 is connected to one side of the vertical side 26. The other side of the vertical side 26 is connected to one side of the horizontal side 27. The other side of the horizontal side 27 is connected to one side of the second vertical side 261, which is parallel to the vertical side 26. The other side of the second vertical side 261... One side of the swing arm 2 is connected to one side of the second horizontal edge 271, the other side of the second horizontal edge 271 is connected to one side of the third vertical edge 262, the other side of the third vertical edge 262 is connected to one side of the third horizontal edge 272, and the other side of the third horizontal edge 272 is connected to the lower part of the arc-shaped edge 21, thus forming an enclosing structure. A hole for the rotating shaft a to pass through is provided in the area formed by the vertical edge 26, the horizontal edge 27, and the second vertical edge 261 on the swing arm 2. The hole is fixedly connected to the rotating shaft a, so that the rotation of the rotating shaft a can drive the swing arm 2 to rotate. The fixed connection method can be a key connection. Specifically, the vertical edge 26, the horizontal edge 27, the second vertical edge 261, the second horizontal edge 271, the third vertical edge 262, the third horizontal edge 272, and the arc-shaped edge 21 are all smoothly transitioned together.

[0023] The drive device provides power to drive the working ring 3 to rotate. Since the working ring 3 is fixedly connected to the rotating shaft a, and the rotating shaft a is fixedly connected to the swing arm 2, the rotation of the working ring 3 can drive the swing arm 2 to rotate. By controlling the power of the drive device, the arc of the swing arm 2 can be controlled so that the swing arm 2 can just transport the steel pipe 7 on the conveying roller 8 to the conveying channel of the next process.

[0024] The specific working process of this utility model is as follows: S1, such as Figure 1 , Figure 3 When the piston end 51 of the oil cylinder 5 retracts, it drives the connecting block 31 to rotate counterclockwise. At the same time, the connecting block 31 drives the working ring 3 and the rotating shaft a to rotate, so that the swing arm 2 also rotates around the rotating shaft a. Finally, the groove 22 reaches one side of the conveying roller 8.

[0025] S2. Under the conveying of the conveying roller 8, only one steel pipe 7 enters the groove 22.

[0026] S3, such as Figure 2 When the piston end 51 of the oil cylinder 5 extends out, it drives the connecting block 31 to rotate clockwise. At the same time, the connecting block 31 drives the working ring 3 and the rotating shaft a to rotate, so that the swing arm 2 also rotates around the rotating shaft a. Finally, the groove 22 reaches one side of the conveying channel 6, and the steel pipe 7 rolls from the groove 22 onto the conveying channel 6, which can be used for single rod conveying.

[0027] During the rotation of the swing arm 2, since the arc-shaped edge 21 is always tangent to the edge of the conveying roller 8, the arc-shaped edge 21 becomes a barrier to the forward movement of the steel pipe on the conveying roller 8. The arc-shaped edge 21 can block the transport of subsequent steel pipes until the swing arm 2 returns to its original state, at which point the transport of the second steel pipe can proceed.

[0028] Then, repeat the above steps to complete the conveying of a single steel pipe.

[0029] Features of this utility model: This utility model provides a steel pipe conveying mechanism for conveying steel pipes one by one. It features a swing arm with an arc-shaped edge, and a groove at the upper part of the arc-shaped edge to accommodate a single steel pipe. The arc-shaped edge is connected to one side of the groove via a first short side, and the height of the first short side is either flush with or below the upper surface of the conveying roller, allowing the steel pipe on the conveying roller to roll into the groove. A driving device drives the swing arm to rotate until the other side of the groove is flush with the upper surface of the conveying channel for the next process, at which point the rotation stops. The single steel pipe in the groove then falls into the conveying channel for the next process. Throughout the rotation of the swing arm, the arc-shaped edge continuously blocks the next steel pipe, thus achieving the conveying of single steel pipes. The device has a simple structure and is easy to use.

[0030] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
