Description

Technical Field

[0001] The utility model relates to the technical field of steel processing, in particular to a small radius steering device. Background Art

[0002] In modern steel enterprises, in order to save energy, protect the environment and improve efficiency, more and more hot delivery rollers are used to transport steel billets, that is, the steel billets cast by the continuous casting machine do not need to be moved to a special site for stacking, and then sent to the heating furnace to be heated to a certain high temperature before being transported to the hot rolling production line. Instead, the hot steel billets output by the continuous casting machine are directly transported to the hot rolling mill for rolling production through high-speed hot delivery rollers. Due to site limitations, the rolling center line of the hot rolling production line is perpendicular to the continuous casting machine output roller production line, or several continuous casting production lines send hot steel billets to several parallel rolling production lines. The hot delivery roller needs to turn vertically or turn at a certain angle. A small radius steering device helps to improve productivity.

[0003] However, in the prior art, the existing hot rolling production line solves the problem of hot billet steering by mainly assembling multiple rollers in a row and gradually increasing the turning angle, arranging them into a group of fan-shaped rollers to achieve the steering of the billet. Such an arrangement has a large turning radius and requires many rollers to be assembled. For a small site area, it may be impossible to arrange rollers, making it difficult to achieve the steering of the billet. There is also a method of steering by assembling two long rollers arranged in parallel and perpendicular to the conveying direction and a sinking output roller, which can achieve the steering of billets with a smaller radius. However, this steering device is relatively complex, and the spacing between the two parallel long rollers is short. The long billet is completely turned on the two rollers, and only the two middle fulcrums support the billet, resulting in a large bending deformation of the hot billet. There is also a method of using two vertically arranged rollers, with a rotating mechanism installed under the rollers. The billet is transported to the steering roller and parked. The rotating mechanism below completes the steering of the roller and the billet. The structure is complex, the speed is low, and it cannot be transported continuously, and the efficiency is low. These methods also cannot complete the steering of multiple groups of billets. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figure 1-3 As shown, the utility model provides a technical solution: a small radius steering device, including: a conveying component 1, the conveying component 1 is a group of conveying components to realize the steering of a single group of steel billets, and can realize small radius steering. A steering component 2 is arranged at one end of the conveying component 1, and the steering component 2 is composed of a plurality of sets of driving rollers 5. The assembly axis of the steering driving roller 5 forms a certain angle with the axis of the conveying roller 5. A conveying component 2 3 is arranged at one end of the steering component 2 away from the conveying component 1, and the conveying component 1 and the conveying component 2 3 are respectively composed of a plurality of sets of driving rollers 5 distributed in parallel. A steel billet is arranged on one side of the conveying component 1, and the steel billet is transported to the conveying component 1. The multi-point support on the roller 5 of the steering component 2 and the transport component 3 can effectively reduce bending deformation. The transport component 1 sends the steel billet to the steering component 2. Driven by the steering component 2 and the roller 5, the steel billet quickly swings and moves toward the direction of the transport component 23 to complete the steering of the steel billet. A roller 5 is arranged on one side of one end of the steel billet, a coupling 6 is arranged on one side of the roller 5, and a frequency-modulated reduction motor 7 is arranged on one end of the coupling 6. The roller 5 is assembled and driven by the frequency-modulated reduction motor 7 to achieve stepless speed regulation. The steering component 2 changes the installation angle θ. By adjusting the rotation speed of the roller 5, a steering of a certain angle α can be achieved, not just a 90° steering.

[0023] In this embodiment, under the instruction of the control system, the conveying assembly 1 drives the steel billet to move along the conveying direction 1 at a speed n1. When the steel billet contacts the roller 5 of the steering assembly 2, the roller 5 of the steering assembly 2 drives the steel billet to swing in the conveying direction 2 at a speed n3. When the steel billet swings and contacts the conveying assembly 23, the roller 5 of the conveying assembly 23 drives the steel billet to move in the conveying direction 2 at a speed n2. At the same time, the roller 5 of the steering assembly 2 continues to drive the steel billet to swing to complete the turning. The axis of the steering assembly 2 forms a certain inclination angle θ with the conveying direction 1, and the conveying direction 2 forms a certain steering angle α with the conveying direction 1. The steering angle α can be 90° or other angles, which are determined according to the requirements of the site. When the steering angle α is determined, the inclination angle θ of the steering assembly 2 arrangement can be calculated according to the size and weight of the steel billet, the required conveying speeds n1 and n2, the turning radius, etc., and the optimal range of the speed n3 of the steering assembly 2 can be calculated and input into the control system. The control system automatically adjusts n2 and n3 according to the actual speed n1 of the conveying assembly 1, so as to complete the continuous and rapid turning of the steel billet.

[0024] Example 2

[0025] like Figure 1-3 As shown, it includes: a conveying component 1, which is a plurality of conveying components, and can realize the steering of multiple groups of steel billets and the steering of small radius. A steering component 2 is arranged at one end of the conveying component 1, and the steering component 2 is composed of a plurality of sets of driving rollers 5. The assembly axis of the steering driving rollers 5 forms a certain angle with the axis of the conveying rollers 5. A conveying component 2 3 is arranged at the end of the steering component 2 away from the conveying component 1, and the conveying components 1 and 2 3 are respectively composed of a plurality of sets of driving rollers 5 distributed in parallel. A steel billet is arranged on one side of the conveying component 1, and the steel billet is transported between the conveying components 1, The multi-point support on the roller 5 of the steering component 2 and the transport component 2 3 can effectively reduce bending deformation. The conveying component 1 sends the steel billet to the steering component 2. Driven by the steering component 2 and the roller 5, the steel billet quickly swings and moves toward the direction of the conveying component 2 3 to complete the steering of the steel billet. A roller 5 is arranged on one side of one end of the steel billet, a coupling 6 is arranged on one side of the roller 5, and a frequency-modulated reduction motor 7 is arranged on one end of the coupling 6. The roller 5 is assembled and driven by the frequency-modulated reduction motor 7 to achieve stepless speed regulation. The installation angle θ of the steering component 2 can adjust the rotation speed of the roller 5, so as to achieve steering of a certain angle α.

[0026] In this embodiment, under the command of the control system, only one steel billet enters the steering assembly 2 along the conveying direction 1 at a time from the conveying assembly 1. By adjusting the rotation speeds n2 and n3, the steel billets of multiple groups of conveying assemblies can enter the steering assembly 2 in sequence to complete continuous and rapid steering and conveying. Similarly, when the steel billet contacts the roller 5 of the steering assembly 2, the roller 5 of the steering assembly 2 drives the steel billet to swing in the conveying direction 2 at a rotation speed n2. When the steel billet swings and contacts the conveying assembly 2, the roller 5 of the conveying assembly 23 drives the steel billet to move in the conveying direction 2, and at the same time, the roller 5 of the steering assembly 2 continues to drive the steel billet to swing to complete the steering. The axis of the steering assembly 2 is at a certain inclination angle θ with the conveying direction 1, and the conveying direction 2 is at a certain steering angle α with the conveying direction 1. The steering angle α can be 90° or other angles, which are determined according to the requirements of the site. When the steering angle α is determined, the inclination angle θ of the steering component 2 can be calculated according to the size and weight of the steel billet, the required conveying speeds n1 and n2, the turning radius, etc., and the range of the speed n3 of the steering component 2 can be calculated and input into the control system. The control system automatically adjusts n2 and n3 according to the rotation speed n1 of the conveying component 1, so as to complete the continuous and rapid steering of multiple groups of steel billets.

[0027] Working principle:

[0028] like Figure 1-3 As shown, the conveying assembly 1 drives the steel billet to move along the conveying direction 1 at a certain speed through the command of the control system. When the steel billet contacts the driving roller 5 of the steering assembly 2, the roller 5 of the steering assembly 2 drives the steel billet to swing in the conveying direction 2 at a certain speed. When the steel billet swings and contacts the conveying assembly 2 3, the driving roller 5 of the conveying assembly 2 3 moves the steel billet in the conveying direction 2 at a certain speed. At the same time, the driving roller 5 of the steering assembly 2 continues to drive the steel billet to swing, completing the steering operation.

[0029] The axis of the steering assembly 2 forms a certain inclination angle θ with the conveying direction 1, while the conveying direction 2 forms a certain steering angle α with the conveying direction 1. The specific steering angle α is determined according to the site requirements. After determining the steering angle α, the inclination angle θ of the steering assembly 2 can be calculated according to the parameters such as the size, weight, required conveying speed and turning radius of the steel billet, and the optimal range of the rotation speed n3 of the steering assembly 2 can be determined. These parameters will be input into the control system, and the control system will automatically adjust the rotation speeds n2 and n3 according to the actual rotation speed n1 of the conveying assembly 1, so as to achieve continuous and rapid steering of the steel billet.

[0030] In addition, in Example 2, the device includes multiple sets of conveying components 1, which can realize the steering of multiple sets of steel billets. The control system's instructions make only one steel billet enter the steering component 2 along the conveying direction 1 at a time, and by adjusting the rotation speeds n2 and n3, the steel billets of multiple sets of conveying components can enter the steering component 2 in sequence, realizing continuous and rapid steering and conveying.

[0031] In summary, the small radius steering device realizes rapid steering of the steel billet by reasonably configuring the conveying assembly and the steering assembly 2 and utilizing the movement of the driving roller 5, thereby meeting site requirements and ensuring the conveying efficiency and quality of the steel billet.
