[0036] As Figures 1-4 Indicated, a kind of steel pipe multi-station switching conveying device, comprising:

[0037] rack 1, rack 1 includes multiple support beams arranged in longitudinal direction parallel, and support beam is equipped with the conveying track of inclined arrangement, and the middle part of rack 1 is equipped with the first notch and the first step of sequentially being arranged along steel pipe conveying direction, and first notch is equipped with the first station extending in longitudinal direction, and first step is equipped with the second station extending in longitudinal direction;

[0038] a group of first conveying roller assembly 2, first conveying roller assembly 2 is arranged at first notch, and the conveying surface of first conveying roller assembly 2 is lower than the conveying surface of the conveying track of rack 1 at first notch;

[0039] first station flap drive mechanism 3, first station flap drive mechanism 3 is arranged at first notch and is arranged staggeredly with first conveying roller assembly 2, and first station flap drive mechanism 3 is equipped with first station flap 31, and first station flap drive mechanism 3 is suitable for driving first station flap 31 reciprocating rotation around its axis;

[0040] The upper surface of the first station turnover plate 31 is provided with an inclined surface connected with the conveying track of the support beam, and the first station turnover plate 31 is adapted to rotate to a blocking position under the drive of the first station turnover plate drive mechanism 3 to block the movement of the steel pipe on the conveying track, or rotate to a lifting position to lift the steel pipe to the conveying track of the rack 1 for continuous conveying, or rotate to a dropping position to drop the steel pipe onto the first conveying roller assembly 2.

[0041] The second station turnover plate drive mechanism 5 is provided at the first step, and the second station turnover plate drive mechanism 5 is provided with a second station turnover plate 51, and the second station turnover plate drive mechanism 5 is adapted to drive the second station turnover plate 51 to rotate reciprocally about its axis.

[0042] The upper surface of the second station turnover plate 51 is provided with an inclined surface connected with the conveying track of the support beam, and the second station turnover plate 51 is adapted to rotate to a blocking position under the drive of the second station turnover plate drive mechanism 5 to block the movement of the steel pipe on the conveying track, or rotate to a lifting position to lift the steel pipe to the conveying track of the rack 1 for continuous conveying.

[0043] In the embodiment, as shown in Figures 1-2 the first station turnover plate 31 can rotate between the dropping position, the lifting position and the blocking position according to production needs under the drive of the first station turnover plate drive mechanism 3. Specifically, when the first station starts production, the first station turnover plate 31 is driven to rotate to the dropping position, so that the steel pipe falls smoothly into the first conveying roller assembly 2 for conveying. When the first station needs to be overhauled or the tooling needs to be replaced, the first station turnover plate 31 can be raised to the lifting position to serve as a transition conveying track, ensuring the continuous transportation of the steel pipe. When the first station needs to pause production or is in use, the first station turnover plate 31 rotates to the blocking position to block the movement of the steel pipe on the conveying track, realizing the control of the steel pipe conveying and ensuring the uninterrupted production process.

[0044] In addition, through the cooperation of the first station turnover plate drive mechanism 3 and the second station turnover plate drive mechanism 5, the steel pipe can realize synchronous production in multiple stations. When the first station is in production, the first station turnover plate drive mechanism 3 can convey the steel pipe from the first station to the second station, realizing the switching between stations.

[0045] In the embodiment, the conveying direction of the steel pipe is transverse, and the longitudinal direction along the length of the steel pipe is longitudinal, and there are seven first conveying roller assemblies 2, including unpowered conveying rollers. Of course, in some embodiments, the number of first conveying roller assemblies 2 is not limited to seven and can be set according to specific needs.

[0046] Specifically, as shown in Figures 1-3As shown in the figure, the first station flap 31 is hinged in the middle on the frame 1, one end of the first station flap 31 extends downward to form a hinged transmission arm 32, the other end forms a bearing plate part, and an inclined surface is arranged on the bearing plate part.

[0047] In the embodiment, as shown in the figure, Figure 2 The angle between the hinged transmission arm 32 and the bearing plate part is less than one hundred and eighty degrees.

[0048] Specifically, as shown in the figure, Figures 1-2 The second station flap 51 is the same structure as the first station flap 31. Specifically, as shown in the figure, Figures 1-3 The first station flap driving mechanism 3 comprises:

[0049] The telescopic driving source 33 is hinged on the frame 1, and the telescopic driving source 33 is provided with a telescopic rod, which is hinged with the hinged transmission arm 32 of the first station flap 31 close to the telescopic driving source 33.

[0050] Specifically, as shown in the figure, Figures 1-3 The first station flap driving mechanism 3 further comprises a connecting rod transmission mechanism, which comprises:

[0051] The hinged transmission arms 32 of two adjacent first station flaps 31 are hinged and connected through the connecting rod 61;

[0052] The telescopic driving source 33 is adapted to drive the connecting rod 61 and the plurality of first station flaps 31 hinged with the connecting rod 61 to reciprocate synchronously through the hinged transmission arm 32 of the first station flap 31 close to the telescopic driving source 33.

[0053] Specifically, as shown in the figure, Figure 3 The telescopic driving source 33 is a double-stroke cylinder.

[0054] In the embodiment, as shown in the figure, Figures 1-3 The first station flap 31 is connected with the frame 1 through the middle hinge point, which serves as a rotation fulcrum to enable the first station flap 31 to rotate around its axis. One end of the first station flap 31 extends to form a hinged transmission arm 32, which is hinged with the telescopic rod of the telescopic driving source 33. The telescopic driving source 33 drives the hinged transmission arm 32 to reciprocate through the telescopic movement of the telescopic rod, thereby realizing the conversion of the first station flap 31 between the lowered position, the lifted position and the blocking position.

[0055] To realize the synchronous rotation of the plurality of first station turn plates 31, the connecting rod transmission mechanism connects the hinged transmission arms 32 of adjacent first station turn plates 31 by connecting rods 61. When the telescopic drive source 33 drives one hinged transmission arm 32, the other hinged transmission arms 32 are driven to move synchronously by the transmission action of the connecting rods 61, so that the plurality of first station turn plates 31 keep synchronous rotation, ensuring the stability of the steel pipe conveying process.

[0056] The telescopic drive source 33 adopts a double-stroke cylinder, and the two strokes of the cylinder correspond to different working positions of the first station turn plate 31 respectively. By controlling the telescopic state of the cylinder, the rotation angle of the first station turn plate 31 is controlled.

[0057] The structure of the second station turn plate driving mechanism 5 is basically the same as that of the first station turn plate driving mechanism 3, and also includes a hinged transmission arm, a connecting rod transmission mechanism and a double-stroke cylinder, which can realize the same rotation control of the second station turn plate 51.

[0058] Specifically, as shown in Figure 1 and Figure 4 , the first conveying roller assembly 2 includes:

[0059] The first drive source 21 is fixedly installed on the rack 1;

[0060] The first conveying roller 22 is rotatably installed on the rack 1, and one end of the first conveying roller 22 is in transmission connection with the output shaft of the first drive source 21.

[0061] Specifically, as shown in Figure 4 , the first drive source 21 is a motor.

[0062] Specifically, as shown in Figure 4 , the two ends of the first conveying roller 22 are respectively provided with limiting convex rings.

[0063] In this embodiment, as shown in Figure 1 and Figure 4 , the first conveying roller assembly 2 is arranged at the first gap for conveying the steel pipe. The first drive source 21 is a motor fixedly installed on the rack 1, and the output shaft of the motor is in transmission connection with one end of the first conveying roller 22. The rotation of the motor drives the first conveying roller 22 to rotate, realizing the conveying function of the steel pipe. The first conveying roller 22 is rotatably installed on the rack 1 by a bearing structure;

[0064] The outer surface of the first conveying roller 22 directly contacts the steel pipe, which is used for bearing the steel pipe and providing conveying power. The two ends of the first conveying roller 22 are provided with limiting convex rings, and the diameter of the limiting convex ring is greater than the outer diameter of the first conveying roller 22. The limiting convex ring guides and limits the steel pipe during the conveying process of the steel pipe, prevents the steel pipe from deviating from the conveying track, and ensures the stability and safety of the conveying process.

[0065] The conveying surface of the first conveying roller assembly 2 is lower than the conveying surface of the conveying runways of the frame 1, forming a height difference. When the first station flap 31 is turned to the lowered position, the steel pipe can be smoothly dropped from the conveying runways into the first conveying roller assembly 2 for conveying.

[0066] Specifically, the multi-station switching conveying device for steel pipes further comprises a steel pipe sawing mechanism (not shown in the figure), which is arranged on one side of the first station.

[0067] In the embodiment, as shown in the figure, Figures 1-2 Figures 1-2 Figures 1-3 Figures 1-3 Figures 1-3 Figure 3 Figures 1-3 Figure 1 Figure 4 Figure 4 The steel pipe sawing mechanism is arranged on one side of the first station and is used for cutting the steel pipe conveyed to the first station. After the steel pipe falls into the first conveying roller assembly 2 through the first station flap 31, the first conveying roller assembly 2 conveys the steel pipe to the steel pipe sawing mechanism for cutting. During the cutting process, the first station flap 31 is kept in the blocking position to prevent new steel pipes from entering the first station. The steel pipe sawing mechanism is a prior art, and the present embodiment will not be described in detail.

[0068] The above specific embodiments further specifically describe the technical problems, technical solutions and beneficial effects solved by the present application. It should be understood that the above description is only for specific embodiments of the present application and is not used to limit the present application.
