Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe production, and specifically relates to a staggered pipe transportation device. Background Art

[0002] The steel pipe has a hollow cross-section and its length is much larger than the diameter or circumference of the steel. In the production of steel pipes, the operation of the steel pipe is a very important logistics process. It is necessary to use a conveying device to transport it to the next position to facilitate the next operation of the steel pipe. The operation of the steel pipe is divided into direct transmission (axial) and transverse transmission. Direct transmission generally uses a rotating V roller, while transverse transmission has various methods: pipe transport trolley, lifting platform, free rolling platform, continuous pipe puller, etc.

[0003] However, the existing steel pipe operating and conveying device generally places the steel pipe directly on the top of the conveyor belt when in use. However, the steel pipe is prone to rolling, colliding and squeezing each other during transportation, causing scratches on the surface of the steel pipe. For this reason, we propose a operating and conveying device for steel pipe processing. Utility Model Content

[0006] Preferably, the staggered length of the conveying portion is 2 / 5 to 3 / 5 of the total length of each wave-shaped portion.

At the same time, due to the presence of waves or serrations on the conveying portion, the steel pipe will not roll randomly during the conveying process, thereby avoiding the steel pipe from rolling and colliding with each other during the transportation process.

[0020] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0021] like Figure 1 As shown, the staggered transport device in this embodiment includes two sets of stands 5 arranged at intervals, a fixed support plate 2 and a movable transport plate 3. The conveying portion 6 can be wavy or serrated. The conveying portion 6 in this embodiment is serrated. The staggered length of the serrations on the conveying portion 6 is approximately 2 / 5~3 / 5 of each segment of the serrations. In this embodiment, the staggered length of the conveying portion 6 is 1 / 2 of the serration length. The lifting mechanism is a conveying cylinder 4. Several conveying cylinders 4 are arranged at intervals. The movable transport plate 3 is connected to the output ends of several cylinders.

[0022] like Figure 2 As shown, the length of each corrugated portion of the conveying portion 6 in this embodiment is 600mm, and the height of the conveying portion 6 is 50mm~100mm. The device can simultaneously convey multiple steel pipes 1, and the spacing between each steel pipe 1 is at least 100mm; the inclination of the side of each corrugated portion of the conveying portion 6 close to the conveying starting end is 35°~50°, and the inclination of the side of each corrugated portion of the conveying portion 6 away from the conveying starting end is 5°~25°, as shown in the figure, wherein the inclination angle of the side of each corrugated portion of the conveying portion 6 close to the conveying starting end is referred to as angle α, and the inclination angle of the side of each corrugated portion of the conveying portion 6 away from the conveying starting end is referred to as angle β. In this embodiment, angle α is 43°, angle β is 7°, and the fixed support plate 2 and the movable transport plate 3 adopt 25mm thick ordinary steel plate.

[0023] like Figure 2As shown, before conveying the steel pipe 1, the steel pipe is first placed between the first sawtooth and the second sawtooth of the fixed support plate 2 and fixed, that is, the steel pipe 101 before operation in the figure. At this time, the piston rod of the conveying cylinder 4 is in a retracted state, and the movable transport plate 3 is lower than the fixed support plate 2. Figure 2 When the steel pipe 1 is conveyed, the piston rod 4 of the conveying cylinder 4 extends upward to push the movable transport plate 3 to a position approximately the same height as the fixed support plate 2. Figure 2 The movable serrated plate 302 is lifted up, and the side with gentle serrations on the movable transport plate 3 lifts up the steel pipe 101 before operation. The steel pipe 1 rolls and slides along the serrations of the movable transport plate 3 from the position of the steel pipe 101 before operation to the inclined surface of the next serration of the fixed support plate 2. Figure 2 The position of the steel pipe 102 in the middle of the operation, at this time, the conveying cylinder 4 drives the movable transport plate 3 to descend, and then the steel pipe 1 continues to roll along the inclined surface of the next sawtooth of the fixed support plate 2 to the end of the next sawtooth. Figure 2 The position of the steel pipe 103 after the operation is completed, and then the piston rod 4 of the conveying cylinder 4 extends upward to push the movable conveying plate 3, and the above process is continued to cycle until the steel pipe 1 is conveyed to the required position.

[0024] When the utility model is used, the staff first moves the steel pipe 1 to the fixed support plate 2 of the device, and starts to transport the steel pipe 1. The piston rod 4 of the transport cylinder 4 extends upward to push the movable transport plate 3. The movable transport plate 3 rises to lift the steel pipe 1. The steel pipe 1 slides forward along the inclined surface of the movable transport plate 3 due to gravity, and then the movable transport plate 3 descends. The steel pipe 1 is transported by the movable transport plate 3 to the upper and lower sawtooth sections of the fixed support plate 2, and then slides forward along the sawtooth inclined surface on the fixed support plate 2, and the above process is repeated until the steel pipe 1 is transported to the desired position. The utility model has high operating efficiency, saves time and efficiency, and at the same time, due to the presence of waves or sawtooth on the conveying part 6, the steel pipe 1 will not roll randomly during the transportation process, avoiding the steel pipe 1 from rolling and colliding with each other during the transportation process; after the steel pipe 1 is transported to the desired position, the utility model can clamp the steel pipe 1 between the sawtooth on the conveying part 6 for positioning, which is convenient for the processing of the steel pipe 1.
