DETAILED DESCRIPTION

[0024] The following are specific embodiments of the utility model and the accompanying drawings to further describe the technical solution of the utility model, but the utility model is not limited to these embodiments.

[0025] Example 1

[0026] like Figure 1-Figure 4 As shown, the rolled steel pipe transmission device includes a transmission platform 1, on which a plurality of bearing seats 2 are linearly distributed, on the inner ring of the bearing seat 2 a plurality of axially stacked transmission rollers 3 are arranged, the stacked transmission rollers 3 are circumferentially provided with arc rollers, on the outer ring of the bearing seat 2 a rotating motor 4 is arranged, and the output end of the rotating motor 4 is transmission-connected to the center of the transmission roller 3.

[0027] That is, the roller shaft is formed by axially connecting a number of circular metal plates in series, and the circumferential arc surface of each conductive roller is used to bear the pipe. Even if the conductive roller 3 is affected by high temperature, it will not be deformed to change the state of the roller. The conductive roller 3 has a larger contact area with the air and can dissipate heat faster. At the same time, it also protects the connected rotating motor 4 from overheating during operation, thereby ensuring the transfer efficiency of the roller.

[0028] In this embodiment, the bearing seat 2 includes a male bearing seat 22 and a female bearing seat 23 which are detachably mounted on the conduction platform 1. The male bearing seat 22 and the female bearing seat 23 are relatively arranged on both sides of the arc roller, and a plurality of conduction rollers 3 are axially arranged in series between the male bearing seat 22 and the female bearing seat 23.

[0029] Each conductive roller 3 is not connected to each other, but is connected in series through the male bearing seat 22 and the female bearing seat 23. Each conductive roller 3 can be replaced, and conductive rollers 3 of different diameters are arranged axially to form various arc-shaped rollers to adapt to different pipe sizes. The heat conduction between the non-integrated conductive rollers 3 is slower, and it is not easy to cause deformation of the integral roller. A single conductive roller 3 also has more contact with the air, so that the heat can be dissipated faster.

[0030] In this embodiment, at least two positioning rods 21 are provided on the axial surface of the inner ring of the male bearing seat 22 . The positioning rods 21 penetrate the conductive roller 3 and the ends of the positioning rods 21 are inserted into the positioning slots of the inner ring of the female bearing seat 23 .

[0031] Holes corresponding to the positioning rods 21 are also provided on the conductive roller 3 for fixing the conductive rollers 3 in series. The conductive roller 3 can be better stabilized by using more than two positioning rods 21 .

[0032] Preferably, two bearing positioning grooves 11 for installing the male bearing seat 22 and the female bearing seat 23 are provided on the conduction platform 1, and a plug-in passage that can be inserted from the edge of the conduction platform 1 is provided on the side wall of the bearing positioning groove 11 away from the rotating motor 4.

[0033] One of the positioning grooves 11 is a groove embedded in the vertical direction, and the other positioning groove 11 is a groove inserted horizontally from the edge of the conductive platform 1. The horizontally inserted groove can match the moving direction of the positioning rod 21 connecting the conductive roller 3 in series and docking the positioning slot.

[0034] Preferably, a rotating motor 4 is provided on the side of the female bearing seat 23 opposite to the conductive roller 3, and the male bearing seat 22 is translated from the plug-in passage into the bearing positioning groove 11 through a slider at the bottom.

[0035] The female bearing seat 23 connected to the rotating motor 4 is not suitable for movement, so it is installed in the vertically embedded positioning groove 11, while the male bearing seat 22 can be inserted into the slide groove positioning groove 11 while being translated and connecting each conductive roller 3 in series.

[0036] In this embodiment, the arc surface of the conductive roller 3 is arranged on the bearing surface 31 , and the arc roller is composed of a plurality of bearing surfaces 31 , so that the cross section of the arc roller is a concave U-shape.

[0037] The conductive rollers 3 have various diameters and are symmetrically arranged in order of large to small from one end of the positioning rod 21, so that an inwardly concave arc roller conveyor can be obtained for the stable passage of the pipe.

[0038] Preferably, the bearing surface 31 is in a platform shape, and each bearing surface 31 is smoothly connected to each other.

[0039] The side arc surface of the platform body has a certain inclination, and the upper bottom surface and the lower bottom surface of two adjacent conductive roller sheets 3 in the series-connected conductive roller sheets 3 overlap each other, and the bottom surface areas are the same or similar, so that the bearing surfaces 31 of each conductive roller sheet 3 can be connected to each other to form a relatively smooth arc surface, thereby minimizing the collision between the roller and the pipe fittings.

[0040] In this embodiment, a plurality of evenly distributed heat dissipation gaps 32 are formed at the edge of the conductive roller 3 , and the heat dissipation gaps 32 on adjacent conductive rollers 3 are arranged at circumferentially staggered angles.

[0041] A plurality of arc-shaped heat dissipation notches 32 are provided at equal angles on the circumference of the conductive roller 3, and the heat dissipation notches 32 on adjacent conductive rollers 3 are staggered to avoid overlapping of the heat dissipation notches 32 so as to reduce the radial compressive strength. When the heat dissipation notches 32 face the pipe fittings, the contact area with the pipe fittings can be reduced, thereby reducing the efficiency of heat conduction. When the heat dissipation notches 32 face away from the pipe fittings, the absorbed heat can be dissipated more quickly through the airflow as the pipe fittings rotate.

[0042] In this embodiment, a plurality of heat dissipation grooves 12 are provided on the conducting platform 1, and the heat dissipation grooves 12 are arranged along the direction of the arc roller.

[0043] A heat dissipation groove 12 is provided below the arc roller to strengthen the air flow in the vertical direction of the arc roller, so that each component on the conduction platform 1 can dissipate heat more quickly and maintain stable operation of the components.

[0044] Example 2

[0045] Based on the technical solution of implementation 1, the arrangement of the bearing seat 2 on the conduction platform 1 is changed, and a rotating motor 4 is arranged on the side of the male bearing seat 22 opposite to the conduction roller 3. The female bearing seat 23 is translated from the plug-in passage into the bearing positioning groove 11 through the slider at the bottom.

[0046] The male bearing seat 22 is fixedly installed in the positioning groove 11 embedded in the vertical direction, and the positioning rod 21 set on the male bearing seat 22 is also fixed accordingly, at this time, the conductive roller 3 can be easily inserted into the positioning rod 21, and finally the female bearing seat 23 is inserted into the end of the positioning rod 21 by translation and sliding, and each conductive roller 3 is axially locked. Setting the bearing seat 2 in this way can make it easier to install and adjust the conductive roller 3.

[0047] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
