[0039] As Figures 1 to 12As shown in the figure, this embodiment proposes a turning and climbing guide groove with adjustable guide wheel spacing, which includes a workpiece input guide groove part 1, a turning guide groove part 2, and a workpiece output guide groove part 3 connected in sequence. The workpiece input guide groove part 1, the turning guide groove part 2, and the workpiece output guide groove part 3 are combined in a spiral distribution. Specifically, the workpiece input guide groove part 1 includes a plurality of first support seats 11, which are arranged at intervals, and each first support seat 11 is provided with a first guide groove 12. The turning guide groove part 2 includes a plurality of second support seats 21 arranged at intervals, and each second support seat 21 is provided with a second guide groove 22. The workpiece output guide groove part 3 includes a plurality of third support seats 31 arranged at intervals, and each third support seat 31 is provided with a third guide groove 32. The first guide groove 12, the second guide groove 22, and the third guide groove 32 are combined into a channel for the workpiece to move. The heights of each first support seat 11, each second support seat 21, and each third support seat 31 gradually increase along the extending direction of the channel. In addition, at least one mounting seat 4 is provided in the first guide groove 12, and / or the second guide groove 22, and / or the third guide groove 32. Each mounting seat 4 is provided with a first guide wheel 41 and an eccentric shaft assembly 5. The first guide wheel 41 can be used to guide the movement of the workpiece, and the eccentric shaft assembly 5 can be used to support and adjust the spacing of the first guide wheel 41. In this way, during the movement of the workpiece along the channel, it can smoothly enter from the workpiece input guide groove part, turn through the turning guide groove part 2, and finally output from the workpiece output guide groove part 3. By gradually increasing the heights of the first support seat 11, the second support seat 21, and the third support seat 31 along the extending direction of the channel, the workpiece can be lifted to the required height while turning along the formed channel in a limited space, so as to deliver the workpiece to the specified next rolling process, which can improve the rolling efficiency and significantly increase the production capacity of the entire production line. At the same time, since the entire guide groove is spirally distributed, it not only saves floor space but also facilitates subsequent installation and maintenance work. In addition, by providing at least one mounting seat 4 in the first guide groove 12, and / or the second guide groove 22, and / or the third guide groove 32, and providing a first guide wheel 41 and an eccentric shaft assembly 5 on the mounting seat 4, the distance between the rotation center line of the eccentric shaft assembly 5 and the center line of the first guide wheel 41 can be adjusted by rotating the eccentric shaft assembly 5, so as to indirectly adjust the spacing of the first guide wheel. The adjusted spacing can compensate for the worn thickness of the guide wheel, greatly improving the utilization rate of the first guide wheel, reducing the replacement frequency of the first guide wheel, and reducing the replacement cost.

[0040] Further, please refer to Figure 2 and Figure 3As shown, the workpiece input chute part 1 includes a first arc beam 13, and the first arc beam 13 is arranged on each first support seat 11. In addition, the first chute 12 includes a plurality of first chute units 121 and a plurality of first support platforms 122. Each first chute unit 121 is arranged at intervals on the first arc beam 13, and each first support platform 122 can be respectively used to support each first chute unit 121. Further, the mounting seat 4 is arranged between two adjacent first chute units 121, and a through hole for the workpiece to pass through is provided on the mounting seat 4. In this way, by arranging a plurality of first support seats 11, the pressure and friction generated during the turning and climbing of the workpiece can be better borne, improving the stability of the workpiece movement. By placing the mounting seat 4 between two first chute units 121, the first guide wheel 41 on the mounting seat 4 can effectively guide the workpiece to move in the first chute 12, improving the smoothness of the workpiece movement, and also helping to reduce the friction between the workpiece and the first chute 12, extending the service life of the equipment. Through the through hole provided on the mounting seat 4, the workpiece can pass through, so that the workpiece can move smoothly in the first chute 12.

[0041] Furthermore, the surface of the first support seat 11 close to the first arc beam 13 is inclined. By setting it to be inclined, the contact area between the first support seat 11 and the first arc beam 13 is increased, thus improving the structural strength of the entire workpiece input chute part. At the same time, this inclined setting also helps the workpiece to move smoothly in the first chute 12, avoiding the phenomenon of shaking or jamming during the turning or climbing of the workpiece, and further improving the stability and accuracy of the workpiece movement. Preferably, the inclination angle of the inclined surface of the first support seat 11 is 2 - 4°. By setting it to this angle, it can be ensured that when the workpiece moves in the first chute 12, it will not generate excessive friction due to too large an angle, nor will the workpiece movement be unstable due to too small an angle.

[0042] Furthermore, please refer to Figure 2 、 Figures 5 to 8As shown, the turning guide groove part 2 includes a second arc beam 23, at least one flap assembly 24, and at least one second guide wheel 25. The first arc beam 13 abuts against the second arc beam 23. The second guide groove 22 is arranged above the second arc beam 23. A first opening is formed at the top of the second guide groove 22. The flap assembly 3 is arranged on the second arc beam 23 and is used to support the second guide groove 22. The second guide wheel 25 is arranged on the second arc beam 23 and is located below the second guide groove 22. In addition, a second opening 26 through which each second guide wheel 25 extends and contacts the rolled piece is formed in the second guide groove 22. By providing at least one flap assembly 24 on the second arc beam 23, it can be used to support the second guide groove 22. By providing at least one second guide wheel 25 on the second arc beam 23 and below the second guide groove 22, the rolled piece can roll forward through the second guide wheel 25, changing the sliding friction of the rolled piece into rolling friction, making the movement smoother and more efficient, and at the same time effectively reducing the noise of the movement of the rolled piece and reducing the wear on the surface of the rolled piece.

[0043] In this application, the surface of the second support base 21 close to the second arc beam 23 is inclined, and the angle of its inclined surface can be adjusted according to actual conditions and is not limited here.

[0044] Preferably, please refer to Figure 2 As shown, the number of pairs of first guide wheels 41 in the second guide groove 22 is multiple pairs, and each pair of first guide wheels 41 and each mounting seat 4 are alternately distributed at intervals. Each pair of first guide wheels 41 is distributed on opposite sides perpendicular to the extending direction of the second guide groove 22. A third opening 27 is formed in the second guide groove 22, and the third opening 27 can allow a pair of first guide wheels 41 to extend and contact the rolled piece. By providing at least one pair of first guide wheels 41 on both sides of the second arc beam 23, the movement track of the rolled piece can be corrected through this pair of first guide wheels 41, improving the accuracy of the movement track and effectively avoiding the occurrence of steel jamming accidents.

[0045] Furthermore, please refer to Figure 8 As shown, the flap assembly 24 includes a base 241, a cover plate 242, a gland 243, and a handle 244. The base 241 is arranged on the second arc beam 23 and is used to carry the second guide groove 22. The cover plate 242 is buckled on the top of the second guide groove 22 to cover the first opening. The gland 243 is rotatably installed on the base 241 and is used to press against the cover plate 242. The handle 244 is rotatably installed on the base 241 and is used to lock the gland 243. Through such a design, the flap assembly 24 can be conveniently opened or closed. When a steel piling accident occurs, the rolled piece in the second guide groove 22 can be taken out by opening the cover plate 242, facilitating the quick removal of scrap steel.

[0046] Furthermore, please refer to Figure 8As shown, in order to improve the connection stability between the gland 243 and the handle 244, an extension plate 245 is provided on the gland 243, and a slot 246 for the extension plate 245 to extend into is formed on the handle 244. When the handle 244 rotates to the locked position, the extension plate 245 will extend into the slot 246, thereby preventing the gland 243 from being accidentally opened.

[0047] Further, please refer to Figure 5 As shown, in order to facilitate the operation of the cover plate 242, a handle 247 is provided on the cover plate 242. The operator can easily open or close the cover plate 242 by holding the handle 247.

[0048] Further, please refer to Figure 8 As shown, a positioning pin 29 is further provided on the second arc-shaped beam 23, and the positioning pin 29 can be used to position the support 28. By providing the positioning pin 29, the support 28 can be accurately positioned.
