[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] like Figures 1 to 6The push rod rotating shaft reversing mechanism shown includes: a rotating shaft 1, multiple push rod mechanisms 2, and a drive assembly 3. The multiple push rod mechanisms 2 are evenly distributed along the axis of the rotating shaft 1, and each push rod mechanism 2 includes a drive rod 21 connected to the rotating shaft 1, and a first rod body 22 and a second rod body 23 disposed at both ends of the drive rod 21. The drive assembly 3 is used to drive the rotating shaft 1 to rotate so that the first rod body 22 and the second rod body 23 alternately rise and fall.

[0038] Multiple gantry 4 are arranged along the length of the crossbeam, and bearing seats 5 are provided on several gantry 4. The rotating shaft 1 is rotatably arranged through the bearing seats 5. The rotating shaft 1 includes an intermediate shaft 11 and two driven shafts 12 connected to both ends of the intermediate shaft 11. The driven shafts 12 are connected to the intermediate shaft 11 through a direct coupling 13.

[0039] This invention utilizes a segmented design with multiple gantry frames 4 and a rotating shaft 1 to provide effective support for the rotating shaft 1, which helps control straightness, effectively maintains the consistency of the push rod lifting height, and improves the stability and reliability of billet output. Furthermore, the segmented design of the rotating shaft 1 facilitates individual inspection and maintenance of different sections, improving the overall system maintenance efficiency.

[0040] In this invention, both the first rod 22 and the second rod 23 include a connecting end 22a hinged to the driving rod 21 and a force-applying end 22b for pushing the steel billet; and the width of the connecting end 22a is greater than the width of the force-applying end 22b, which reduces stress concentration at the hinge point, reduces wear caused by repeated movement, and increases connection reliability.

[0041] Based on the above scheme, the first rod 22 and the second rod 23 are both provided with reinforcing ribs 24 on the outer side of the force-applying end 22b, which can increase the contact area with the steel billet and enhance the rod's resistance to deformation. In order to prevent the heat of the steel billet from affecting the transmission of the push rod mechanism during the pushing process, the reinforcing ribs 24 are made of heat-insulating material to block the heat transfer. In addition, the connection between the reinforcing ribs 24 and the rod can be fixed in one piece by welding or detachably connected by bolts, which improves the convenience of replacing the reinforcing ribs 24.

[0042] To prevent lateral displacement when the first rod 22 or the second rod 23 pushes the steel billet, preferably, multiple guide plates 6 are provided on both sides of the crossbeam along its length; a limiting groove for the first rod 22 or the second rod 23 is formed between two adjacent guide plates 6, reducing accidental movement caused by improper operation or external force, and enhancing the safety of operation.

[0043] In a preferred embodiment of the present invention, the drive rod 21 includes two symmetrically arranged cantilever arms 211. Each of the two cantilever arms 211 is provided with a connecting flange 212 at the end away from the hinge point. The two cantilever arms 211 are fixed to the rotating shaft 1 through the connecting flange 212.

[0044] The design of the symmetrical cantilever 211 helps to reduce the dynamic load caused by inertial forces, thereby reducing the impact and vibration on the entire system, improving the system's lifespan and reliability. The flange connection ensures a firm and reliable connection between the drive rod 21 and the rotating shaft 1, reducing the possibility of loosening during long-term operation.

[0045] As a preferred embodiment of the above, the cantilever 211 includes a first side plate and a second side plate arranged in parallel, forming an installation space between the first side plate and the second side plate to accommodate the first rod 22 or the second rod 23; a connecting plate is provided in the installation space at the end away from the hinge point, and the connecting plate is fixed to the connecting flange 212 by bolts. The design of the two side plates and the connecting plate improves the stability of the entire cantilever 211 structure.

[0046] Based on the above scheme, a plate 213 is provided at the contact position between the connecting plate and the connecting flange 212. The plate 213 can evenly transmit the force to the connecting flange 212 and the drive rod 21, avoiding damage caused by excessive local stress, increasing the connection strength between the drive rod 21 and the connecting flange 212, and ensuring the stability of the connection.

[0047] To ensure the reliability of power transmission, a circumferential limiting member 7 is provided on the contact surface between the connecting flange 212 and the rotating shaft 1, which can ensure the synchronization of the connecting flange 212 and the rotating shaft 1 in the circumferential direction. The preferred structure is that the rotating shaft 1 and the connecting flange 212 are circumferentially limited by a flat key.

[0048] In a preferred embodiment of the present invention, the drive assembly 3 includes a hydraulic cylinder 31 located at the middle position of the rotating shaft 1 and a rocker arm 32 connected to the end of the drive rod 21 of the hydraulic cylinder 31; one end of the rocker arm 32 is connected to the hydraulic cylinder 31 and the other end is connected to the rotating shaft 1.

[0049] The design of the rocker arm 32 connecting the hydraulic cylinder 31 and the rotating shaft 1 can effectively convert the linear motion generated by the hydraulic cylinder 31 into rotational motion. Specifically, the hydraulic cylinder 31 drives the rocker arm 32 to rotate around the axis of the rotating shaft 1, while the rotating shaft 1 rotates synchronously to achieve the switching between the first rod body 22 and the second rod body 23.

[0050] In a preferred embodiment of this utility model, the rotating shaft 1 is provided with a stepped shaft section 1a at the installation position of the drive rod 21, which provides a precise positioning reference for the drive rod 21 and ensures the accuracy and consistency of the drive rod 21 during installation.

[0051] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
