Technical Field

[0001] The utility model belongs to the auxiliary equipment for steel pipe production and manufacturing, and particularly relates to a steel pipe transmission device unit and a steel pipe transmission device. Background Art

[0002] In the manufacturing of steel pipes, it is often necessary to move steel pipes. Small-sized steel pipes can be hoisted, but for large-sized and heavy steel pipes, it is difficult to hoist them, and a steel pipe transmission device is required. At present, the bearing capacity of the existing steel pipe transmission device is not ideal. When a heavy steel pipe is placed on its transmission roller, the middle part of the transmission roller will be deformed, affecting the transmission effect of the steel pipe. In the long run, it will also affect the service life of the steel pipe transmission device. Summary of the Utility Model

[0003] Based on the content in the background art, the utility model discloses a steel pipe transmission device unit and a steel pipe transmission device.

One end of the first idler and the second idler facing each other is fixedly connected by a straight shaft. The other ends of the first idler and the second idler are respectively matched with the corresponding first bearing seats through a rotating shaft and a bearing. The end of the rotating shaft of the first idler is also connected with a driving motor, and the driving motor is specifically a reduction motor. Thus, under the drive of the driving motor, the first idler and the second idler can rotate along their own axes;

[0006] The support roller is located below the straight shaft. A second bearing seat is respectively arranged on both sides of the support roller. Both ends of the support roller are respectively matched with the corresponding second bearing seats through a rotating shaft and a bearing. At least one convex ring is fixedly connected to the straight shaft. A groove is formed on the surface of the support roller at the position corresponding to the convex ring, and a part of the convex ring is located in the groove of the support roller, and the rolling surface of the convex ring abuts against the inner surface of the groove of the support roller.

[0007] When a steel pipe is placed on the steel pipe transmission device unit, at the center of the first idler and the second idler, that is, at the straight shaft, due to the cooperative setting of the support roller and the convex ring of the straight shaft, the support roller can stably support the straight shaft, avoiding deformation due to the weight of the steel pipe and affecting the transmission effect of the steel pipe. The steel pipe thereon can be better supported and carried, and the service life of the steel pipe transmission device can also be extended.

[0008] Preferably, both the first idler and the second idler are frustum-shaped, and the smaller frustum bases of the first idler and the second idler are arranged opposite to each other.

[0010] Preferably, a flexible rubber sleeve is sleeved on the convex ring. The flexible rubber sleeve is made of rubber material, which can play a buffering role and can prevent the rolling surface of the convex ring from directly contacting the inner surface of the groove of the support roller rigidly.

[0011] A disclosed steel pipe transmission device includes a plurality of steel pipe transmission device units as described above. Each steel pipe transmission device unit is arranged in a straight line, and there is a gap between adjacent steel pipe transmission device units. When the steel pipe is placed on the steel pipe transmission device, the steel pipe can be stably transmitted under the drive of the drive motor.
