[0002] As a core piece of equipment in industrial heat treatment, heating furnaces are widely used in processes such as annealing, normalizing, and quenching of metal materials. Traditional heating furnace material handling systems often rely on manual hoisting operations, requiring manual labor or external equipment to complete loading and unloading operations. Especially in multi-layer furnace structures, materials need to be moved between different layers via ground cranes or additional transfer devices, resulting in insufficient efficiency and automation, frequent manual intervention, slow material handling speed, and susceptibility to material displacement or collisions due to operational errors, affecting production cycle and safety. Utility Model Content

[0003] To solve the above technical problems, this utility model provides a lifting device for a heating furnace and a heating furnace. By setting up independent loading and unloading layers and a lifting mechanism, it reduces manual intervention in the material loading and unloading process, realizes automatic material loading and unloading, simplifies the operation process, and improves loading and unloading efficiency.

[0007] The material feeding layer includes several second idlers;

[0008] The lifting mechanism, located on one side of the upper and lower material layers, has a drive component, a lifting platform on the drive component, and a third idler roller on the lifting platform. The drive component drives the lifting platform to move up and down, enabling the lifting platform to reach either the upper or lower material layer. By setting up independent upper and lower material layers and lifting mechanisms, manual intervention in the material loading and unloading process is reduced, automatic material loading and unloading is achieved, the operation process is simplified, and the loading and unloading efficiency is improved.

[0009] Preferably, the lifting platform has a first position and a second position.

In the second position, the lifting platform reaches the lower material layer, and the third roller on the lifting platform is at the same height as the second roller on the lower material layer. This ensures that the material remains horizontal and stable during transfer, avoids friction, jamming, or material deviation caused by height differences, and improves the reliability of the transfer.

[0010] Preferably, the lifting platform has a third position, in which the lifting platform is flush with the ground, which facilitates loading or unloading materials directly from the ground, reduces the intensity of manual handling, improves operational convenience and safety, and expands the application scenarios of the device.

[0011] Preferably, the lifting mechanism also includes a longitudinally arranged guide rail, and a guide wheel matching the guide rail is provided on one side of the lifting platform, which enhances the vertical guidance of the lifting platform movement, prevents the platform from shaking or deviating during the lifting process, improves operational stability, and reduces mechanical wear and failure risk.

[0012] Preferably, the inlet of the feeding layer is provided with inclined guides on both sides, which can guide the material to automatically adjust its position when entering the feeding layer, avoid the material from colliding or deviating from the edge of the inlet, reduce the need for manual intervention, and improve feeding accuracy and efficiency.

[0013] Preferably, the feeding layer is equipped with centering guide rollers arranged in a trumpet shape, which can automatically guide the material to the center position, solve the problem of material deviation caused by inertia or placement deviation, ensure that the material is heated evenly in the heating furnace, and improve the processing quality.

[0014] A heating furnace includes a lifting device, which enables the heating furnace to have efficient and stable multi-layer material transfer capabilities, reduce manual operation steps, and improve overall production efficiency and equipment automation level.

[0015] Preferably, the heating furnace is one of a walking beam furnace, an annealing furnace, or a normalizing furnace, and the lifting device is suitable for various heat treatment scenarios.

[0016] Preferably, each material frame station on the upper and lower material layers has an individual photoelectric switch and reducer to achieve precise station-level control. It can detect the material position in real time and adjust the transfer speed, avoid interference between multiple stations, and improve the system response speed and safety. If the material is not loaded in time, the subsequent material frame will be automatically transported to the empty material frame position.

[0017] Preferably, the feeding direction of the upper layer is opposite to the discharging direction of the lower layer, which facilitates feeding and discharging.

[0018] Compared with the prior art, the present invention has the following advantages: The present invention provides a lifting device for a heating furnace and a heating furnace. By setting up an independent loading layer, unloading layer and lifting mechanism, the lifting platform of the lifting mechanism can reach the loading layer, unloading layer and the ground, realize the loading and unloading process of materials, reduce manual intervention in the loading and unloading process of materials, simplify the operation process and improve loading and unloading efficiency.

Detailed Implementation

[0024] To facilitate understanding of the technical solution of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figures 1-4 As shown, a lifting device for a heating furnace includes:

[0027] The feeding layer 1 includes several first idler rollers 1-1;

[0028] The feeding layer 2 includes several second idlers 2-1;

[0029] The lifting mechanism 3 is located on one side of the upper material layer 1 and the lower material layer 2, and has a drive component 3-1, a lifting platform 3-2 located on the drive component 3-1, and a third idler roller 3-3 located on the lifting platform 3-2; the drive component 3-1 drives the lifting platform 3-2 to rise and fall so that the lifting platform 3-2 can reach either the upper material layer 1 or the lower material layer 2.

[0030] By setting up independent loading and unloading layers and lifting mechanisms, manual intervention in the material loading and unloading process is reduced, realizing automatic material loading and unloading, simplifying the operation process, and improving loading and unloading efficiency.

[0031] The lifting platform 3-2 has a first position and a second position. In the first position, the lifting platform 3-2 reaches the upper material layer 1, and the third roller 3-3 on the lifting platform 3-2 is at the same height as the first roller 1-1 on the upper material layer 1. In the second position, the lifting platform 3-2 reaches the lower material layer 2, and the third roller 3-3 on the lifting platform 3-2 is at the same height as the second roller 2-1 on the lower material layer 2. This ensures that the material remains horizontal and stable during transfer, avoids friction, jamming, or material deviation caused by height differences, and improves the reliability of the transfer.

[0032] In this embodiment, the upper material layer 1 is located above the lower material layer 2, therefore the first position is located above the second position. In actual use, the positions of the upper material layer 1 and the lower material layer 2 can be set according to requirements.

[0033] The lifting platform 3-2 has a third position. In the third position, the lifting platform 3-2 is flush with the ground, which facilitates loading or unloading materials directly from the ground, reduces the intensity of manual handling, improves the convenience and safety of operation, and expands the application scenarios of the device.

[0034] In operation, the material is placed in the material frame and moved to the lifting platform 3-2 by a forklift or ground transport device. Then, the drive assembly 3-1 drives the lifting platform 3-2 to the upper material layer 1. The third idler roller 3-3, through a reducer, moves the material frame onto the first idler roller 1-1 of the upper material layer 1 and moves it inward for processing. After processing, the material is moved to the lower material layer 2 by an internal lifting device. The second idler roller 2-1 of the lower material layer 2 then transports the material frame outward. The drive assembly 3-1 drives the lifting platform 3-2 to the lower material layer 2, and after receiving the material frame, it descends to the ground. The drive assembly 3-1 can be a hydraulic assembly.

[0035] The lifting mechanism 3 also includes a longitudinally arranged guide rail 3-4. A guide wheel 3-5 matching the guide rail 3-4 is provided on one side of the lifting platform 3-2, enhancing the vertical guidance of the lifting platform's movement, preventing platform swaying or deviation during lifting, improving operational stability, and reducing mechanical wear and the risk of failure. The guide rail 3-4 is connected and fixed to the frame of the upper material layer 1 and the lower material layer 2 on one side.

[0036] The feeding layer 1 has inclined guide members 1-2 on both sides of the inlet, which can guide the material to automatically adjust its position when entering the feeding layer, avoid the material from colliding with or deviating from the inlet edge, reduce the need for manual intervention, and improve feeding accuracy and efficiency. The guide members 1-2 can be inclined angle steel or channel steel.

[0037] The feeding layer 1 is equipped with centering guide wheels 1-3 arranged in a trumpet shape, which can automatically guide the material to the center position, solve the problem of material deviation caused by inertia or placement deviation, ensure that the material is heated evenly in the heating furnace, and improve the processing quality.

[0038] In addition, the unloading layer 2 is also equipped with guides and centering guide wheels, the direction of which is opposite to that of the guides 1-2 and centering guide wheels 1-3 of the loading layer 1, so they will not be described in detail.

[0039] A heating furnace includes a lifting device, which enables the heating furnace to have efficient and stable multi-layer material transfer capabilities, reduce manual operation steps, and improve overall production efficiency and equipment automation level.

[0040] The heating furnace is one of a walking beam furnace, an annealing furnace, or a normalizing furnace, and the lifting device is suitable for various heat treatment scenarios.

[0041] Each material frame station on the upper material layer 1 and the lower material layer 2 is equipped with an individual photoelectric switch 4 and a reducer 5, enabling precise station-level control. The material position can be detected in real time and the transfer speed can be adjusted to avoid interference between multiple stations and improve system response speed and safety. If material is not loaded in time, the subsequent material frame will be automatically transported to the empty material frame position.

[0042] The feeding direction of the upper layer 1 is opposite to the discharge direction of the lower layer 2, which facilitates feeding and discharging.
