[0024] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive of other embodiments.

[0025] Embodiment 1

[0026] Reference Figures 1-4 For the first embodiment of the present application, the embodiment provides a steel feeding device, specifically comprising a vehicle body mechanism 100, which comprises a connecting rod 101, and a support frame assembly 102 arranged at both ends of the connecting rod 101; a moving mechanism 200, which comprises a rotating shaft 201 rotatably arranged at the lower part of the support frame assembly 102, and a rotating wheel assembly 202 arranged at both ends of the rotating shaft 201; a transportation mechanism 300, which comprises a roller seat 301 arranged at the upper part of the support frame assembly 102, and an idler roller 302 installed in the roller seat 301.

[0027] Further, the support frame assembly 102 comprises a first support frame 102a fixed at one end of the connecting rod 101, and a second support frame 102b fixed at the other end of the connecting rod 101.

[0028] Preferably, the support frame assembly 102 further comprises a roll changing pull hook 102c fixed on the side wall of the first support frame 102a, and the roll changing pull hook 102c is fixed at one end of the first support frame 102a which is wider than the other end away from the first support frame 102a.

[0029] In the embodiment, the vehicle body mechanism 100 is composed of welding, and the welding part can be supplemented with reinforcing ribs to improve the overall strength of the vehicle body mechanism 100, and the connecting rod 101 between the support frame assemblies 102 contains gaps, which can facilitate the maintenance of the vehicle body mechanism 100 by the operator.

[0030] Embodiment 2

[0031] Reference Figures 1-4 For the second embodiment of the present application, the embodiment is based on the previous embodiment.

[0032] Specifically, the rotating shaft 201 protrudes out of the outer wall of the mechanism 100 at both ends; the rotating shaft 201 is provided with not less than three groups.

[0033] It should be noted that, Figure 2 The four groups of rotating shafts 201 are provided in the middle, in the actual use process, the rolling blank single weight is more than 6 tons, the filling roller length is 2.8 meters, and the length of the seat roller frame is more than 4 meters. The entire filling roller weighs 10 tons. Four groups of rotating shafts 201 are used according to their length and bearing to achieve the purpose of stability, and also facilitate the overall push-in and pull-out of the steel feeding device.

[0034] Further, the rotating wheel assembly 202 includes a common wheel 202a provided at one end of the rotating shaft 201, and a "V" shaped wheel 202b fixed at the other end of the rotating shaft 201; all "V" shaped wheels 202b are provided at the same end of all rotating shafts 201.

[0035] It should be noted that the "V" shaped wheel 202b can be adapted to the "V" shaped protrusion on the input side of the track, which can constrain the overall steel feeding device to move in the input direction; the contact surface of the common wheel 202a with the track is planar, which ensures that the direction is pushed in along the input side "V" track direction during the push-in process, preventing the track and the "V" shaped wheel 202b from being blocked or deviated during the push-in process.

[0036] Further, the "V" shaped wheel 202b has a "V" shaped groove H-1 in the middle, and the symmetry axes of all "V" shaped grooves H-1 are the same.

[0037] It should be noted that the symmetry axes of the "V" shaped grooves H-1 are the same, which can better adapt the input side "V" track.

[0039] Preferably, the roller seat 301 is fixedly connected to the upper surfaces of the first support frame 102a and the second support frame 102b by bolts.

[0040] It should be noted that the roller surface height of the idler roller 302 is designed to be consistent with the roller surface height of the rack roller, which can avoid the consumption of kinetic energy during the transportation of the steel billet, thereby ensuring the smooth passing of the steel billet; the idler roller 302 adopts a free roller mode, thereby simplifying the structure of the entire device and reducing the process of disconnecting the circuit when replacing the device, thereby achieving the purpose of rapid replacement.

[0041] In the embodiment, the work roll chock is replaced by the roller chock 301 of the conveying roller way, the uniformity of the roll changing process is realized, the convenience of the replacement is improved, and the types and quantities of the spare parts are compressed. When the main drive of the rolling mill needs to be maintained, the roller chock 301 is installed on the support frame assembly 102, filled into the lower work roll position, no driving device is applied, the idler roll 302 is freely rotated, the inertia of the rolled piece is formed by the conveying roller way, the effect of the blank slab emptying is achieved. Before the steel is lifted and rolled by the steel feeding device, the number of the rolling blocks per hour is about 11, after the filled roll is used, the number of the rolling blocks per hour is about 16, taking 40 hours of maintenance as an example, the average block weight is 7.5 tons, the output is increased by about 1500 tons, and the expected effect is achieved.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
