[0006] A protective cover is installed on the upper part of the first conveyor frame, the second conveyor frame and the third conveyor frame to prevent the steel billet from running out;

[0007] A guide assembly, mounted on the protective cover, for guiding the steel billet in the first conveyor frame;

[0008] Wherein, the guide assembly includes a baffle, a mounting plate, a first connecting member, a first connecting shaft, a linear moving member and a second connecting member, the end of the baffle is rotatably connected to the protective cover, the upper side of the baffle is fixedly connected to the mounting plate, the first connecting shaft is fixedly connected to the mounting plate, the second connecting shaft is fixedly connected to the protective cover, the first connecting member is rotatably connected to the first connecting shaft and fixedly connected to the output shaft of the linear moving member, and the second connecting member is rotatably connected to the second connecting shaft and fixedly connected to the linear moving member.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] The driving assembly 4 has three groups correspondingly mounted on the first conveying frame 1, the second conveying frame 2 and the third conveying frame 3, and is used to drive the steel billet 6 to move;

[0033] A protective cover is installed on the upper part of the first conveyor frame 1, the second conveyor frame 2 and the third conveyor frame 3 to prevent the steel billet 6 from running out;

[0034] A guide assembly 5, mounted on the protective cover 7, is used to guide the steel billet 6 in the first conveyor frame 1;

[0035] The guide assembly 5 includes a baffle 501, a mounting plate 502, a first connecting member 503, a first connecting shaft 504, a linear motion member 505 and a second connecting member 506. The end of the baffle 501 is rotatably connected to the protective cover 7. The upper side of the baffle 501 is fixedly connected to the mounting plate 502. The first connecting shaft 504 is fixedly connected to the mounting plate 502. The second connecting shaft 507 is fixedly connected to the protective cover 7. The first connecting member 503 is rotatably connected to the first connecting shaft 504 and is fixedly connected to the output shaft of the linear motion member 505. The second connecting member 506 is rotatably connected to the second connecting shaft 507 and is fixedly connected to the linear motion member 505.

[0036] The driving assembly 4 located on the first conveyor frame 1 includes a motor 401 and a conveyor roller 402. The conveyor roller 402 is rotatably connected to the first conveyor frame 1. The motor 401 is detachably mounted on the first conveyor frame 1 and is fixedly connected to the conveyor roller 402.

[0037] Preferably, the motor 401 is detachably connected to the first conveyor frame 1 by a bolt assembly. Relevant technical personnel in the field should know that the purpose of this arrangement is to limit the motor 401 to the first conveyor frame 1. Therefore, in some embodiments, the motor 401 can also be detachably connected to the first conveyor frame 1 by snap-fitting, or fixedly connected to the first conveyor frame 1 by welding.

[0038] Preferably, the linear moving part 505 is a cylinder. Those skilled in the art should know that the purpose of this configuration is to push the baffle 501 to rotate. Therefore, in some embodiments, the linear moving part 505 can also be configured as either a hydraulic cylinder or an electric push rod.

[0039] Preferably, the protective cover 7 at the intersection of the first conveyor frame 1 , the second conveyor frame 2 and the third conveyor frame 3 is in a Y-shape.

[0040] Preferably, two pressure sensors 509 are symmetrically installed on the baffle 501, and an arc plate 508 is fixedly installed on the pressure sensor 509. The purpose of this arrangement is to detect the pressure between the arc plate 508 and the protective cover 7 to prevent excessive pressure between the arc plate 508 and the protective cover 7, thereby preventing damage to the protective cover 7.

[0041] Preferably, a magnetic angle sensor for detecting the rotation angle of the baffle 501 is also installed on the baffle 501 . The purpose of this arrangement is to detect the rotation angle of the baffle 501 to prevent the baffle 501 from hitting the protective cover 7 .

[0042] In the embodiment of the present invention, the motor 401 can drive the conveying roller 402 to rotate in the horizontal direction, and then use a number of rotating conveying rollers 402 to push the steel billet 6 located thereon to move. When the steel billet 6 chooses to enter the second conveying rack 2 or the third conveying rack 3 from the first conveying rack 1, it is only necessary to start the linear moving part 505. The linear moving part 505 pushes the baffle 501 to rotate, thereby causing the first conveying rack 1 to be unobstructed with one of the second conveying rack 2 or the third conveying rack 3, thereby achieving the technical effect of turning and transporting the steel billet 6 located in the first conveying rack 1.

[0043] The method for using the above-mentioned direct rolling roller reversing device comprises the following steps:

[0044] S1, obtaining the pressure information between the arc plate 508 and the protective cover 7 through the pressure sensor 509, and obtaining the rotation angle of the baffle 501 through the magnetic angle sensor;

[0045] S2, comparing the acquired pressure information and rotation angle information with the preset pressure threshold and rotation angle threshold. If either the pressure information or the rotation angle information reaches the corresponding threshold, it indicates that the baffle 501 has preliminarily reached the preset position.

[0046] S3. When the baffle 501 initially reaches the preset position, continue to drive the baffle 501 to rotate, and obtain the rotation angle information and pressure information. After dimensionless processing, the obtained rotation angle information and pressure information are introduced into the rotation position quality assessment model, and the rotation position quality coefficient is output. The obtained rotation position quality coefficient is compared with the preset rotation position quality coefficient threshold. If the obtained rotation position quality coefficient is within the rotation position quality coefficient threshold, it indicates that the baffle 501 rotates to the target position. If the rotation position quality coefficient is not within the rotation position quality coefficient threshold, the linear moving part 505 is started to push the baffle 501 to rotate continuously, so as to change the rotation angle information and pressure information until the rotation position quality coefficient is within the rotation quality coefficient threshold. The rotation position quality assessment model is expressed as:

[0047]

[0048] Wherein, ZW(F,w) represents the rotation position quality coefficient, F represents pressure information, w represents rotation angle information, α represents the pressure information influence factor, β represents the rotation angle information influence factor, represents the influence factor of temperature on the quality of the baffle 501, 0.72≤α≤0.93, 0.84≤β≤0.97, 0.25≤T≤0.51.
