[0039] Lifting roller belt 100, which includes:

[0040] The lifting roller belt frame includes an inner roller belt frame 101 and an auxiliary inner frame 102. The inner roller belt frame 101 is the main support structure for lifting the roller belt and is used to support the roller belt. The auxiliary inner frame 102 is mounted on the inner roller belt frame 101 to strengthen the structural strength of the inner frame and to install the roller belt drive motor 104. This split design facilitates installation and maintenance while ensuring the stability of the overall structure.

[0041] The lifting roller belt 100 serves as the supporting structure for the entire device. It is constructed from welded steel and possesses sufficient strength and rigidity to support the weight of the billet. The frame surface is treated with rust prevention to extend its service life.

[0042] Lifter 105: It uses four sets of hydraulic cylinders arranged at the four corners of the frame to achieve overall lifting through synchronous control. Four sets of hydraulic cylinders are selected to ensure smooth lifting, avoid uneven movement caused by off-center loading, and provide sufficient load-bearing capacity.

[0043] Roller belt: Designed with 3 parallel roller groups 103, each roller group 103 contains 9 evenly distributed rollers, for a total of 27 rollers. The arrangement direction of the roller groups is perpendicular to the movement direction of the rolling mill roller table at 90 degrees. This 3×9 layout design fully considers the size and weight distribution of the billet, ensuring stable support of the billet during transportation and avoiding deformation.

[0044] Roller belt drive machine 104: Each roller group 103 is equipped with an independent drive machine, and there are three independent transmissions. The advantages of independent transmission design are: each group of rollers can be controlled independently according to the position of the blank, the load of a single drive machine is reduced, the system reliability is improved, and a single drive machine failure does not affect the overall operation.

[0045] In some embodiments of the present application, the center line of the jacking roller belt is collinear or parallel to the center line of the heating furnace.

[0046] Embodiment 2: Roller structure design

[0047] This embodiment focuses on the structure design of the roller. The roller is a key part of the entire device, and its design features are:

[0048] Integrated structure: The roller 106 tightly integrates the seat body 1061, the roller 1062, the bearing 1063, and the chain wheel 1064 into one. This design has the following advantages: reducing the number of parts, improving reliability, easy installation and maintenance, more stable operation, and prolonging the service life;

[0049] The seat body 1061 is designed with an opening at the top with a width greater than the diameter of the roller shaft 1066, which facilitates installation and maintenance. A bearing seat is provided on both sides of the seat body 1061, which is made of high-strength alloy steel and has a surface that has been quenched to improve wear resistance.

[0050] Transmission mode: The roller is connected to the roller belt drive machine 104 through the chain wheel 1064 and the chain. The reason for using chain transmission is: high transmission efficiency, no slip, easy maintenance and replacement, and reliable operation.
