Description

Technical Field

[0001] The utility model belongs to the technical field of billet production, and particularly relates to a billet lifting and supporting device. Background Art

[0002] In the production process of the iron and steel industry, as an important raw material, after being produced in the steel mill, billets often need to go through a series of processing operations, including the conveying process from a lower position to a higher position. This conveying process is crucial for the smooth operation of the entire production line. However, in actual operation, due to the influence of various factors, problems such as falling and deviation often occur during the lifting of billets, which not only damages equipment but also seriously disrupts the production rhythm, thereby reducing output and efficiency.

[0003] Specifically, the problems that billets may encounter during the lifting process mainly include the following aspects:

[0004] Bending of billets: Due to various factors in the production process, billets may have a certain degree of bending. This bending will cause unstable contact between the billet and the supporting device during the lifting process, thereby increasing the risk of falling.

[0005] Tightness of the lifting chain: As a key component connecting the billet and the supporting device, the tightness of the lifting chain has a direct impact on the stability of the billet. If the lifting chain is too loose, the billet may shake during the lifting process; if it is too tight, it may cause excessive pressure on the chain and the supporting device, resulting in damage.

[0006] Angle and position of the lifting pallet: The lifting pallet is the main component for supporting the billet, and the setting of its angle and position is crucial for the stability of the billet. If the angle or position of the pallet is improper, the billet may shift or fall during the lifting process.

[0007] In order to solve the above problems, various solutions have been proposed in the prior art, but they often have disadvantages such as complex structure, difficult maintenance, and high cost. Therefore, there is an urgent need for a billet lifting and supporting device with a simple structure, stable and reliable performance, and low cost to ensure the stability and safety of billets during the lifting process.

It is characterized in that: a lifting pallet assembly is provided at one of the links of the lifting chain, and the lifting pallet assembly includes two parallel L-shaped supporting pallets, and the horizontal plates of the two supporting pallets are connected to the upstream and downstream chain links of the lifting chain through a pin shaft.

[0010] Further preferably, guide wheels are provided at both ends of the pin shaft, and guide grooves for accommodating the guide wheels are installed on the chain beam corresponding to the guide wheels.

[0011] Further preferably, a horizontal support plate is horizontally installed on the vertical plates of the two L-shaped support plates.

[0012] Further preferably, the horizontal support plate is detachably installed on the upper end surface of the support plate.

[0013] Further preferably, a cushion block is detachably installed on the lifting link adjacent to the upstream of the lifting support plate assembly.

[0014] Advantages and technical effects of the present utility model: The present utility model is proposed based on this background. By designing a billet lifting and supporting device including a chain beam, a lifting chain and a lifting support plate assembly, it can not only effectively solve the problems that may be encountered during the lifting of billets, but also improve the operation efficiency and output of the production line. Specifically, the present utility model adopts two parallel L-shaped support plates, connects them to the upstream and downstream links of the lifting chain through a pin shaft, and at the same time uses the cooperation of guide wheels and guide grooves to ensure the stability and safety of the billet during the lifting process.

[0018] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] Please refer to Figure 1 and Figure 2, A billet lifting and supporting device, including a chain beam 1. The chain beam 1 ensures the stability and straightness of the lifting chain 2 during operation, preventing the billet from being unstable due to the shaking of the chain. At the same time, the firm design of the chain beam 1 also improves the safety and load-bearing capacity of the entire device; The lifting chain 2 is arranged between the chain beams. The lifting chain 2 realizes the smooth lifting of the billet through the tight connection of its chain links and the drive of the sprocket. Its strength and wear resistance ensure the stability and reliability during long-term operation; A lifting support plate assembly 3 is provided at one of the links of the lifting chain. The design of the lifting support plate assembly 3 enables the billet to be stably supported during lifting, preventing falling and deviation; The lifting support plate assembly includes two parallel L-shaped support plates 3-1. The two parallel L-shaped support plates 3-1 form a stable support surface. Even if the billet has a certain degree of bending or irregular shape, it can be effectively supported, preventing the billet from shaking and falling during lifting; The horizontal plates of the two support plates are connected to the upstream link 2-1 and the downstream link 2-2 of the lifting chain through a pin shaft 3-2; The connection method of the pin shaft 3-2 enables the L-shaped support plate 3-1 to rotate freely with the movement of the lifting chain 2. This not only ensures the flexible adaptation of the support plate to the billet but also prevents the support from being unstable due to changes in the chain tightness. At the same time, the pin shaft connection also facilitates the maintenance and replacement of the support plate.

[0020] Further preferably, guide wheels 3-3 are provided at both ends of the pin shaft, and guide grooves 3-4 for accommodating the guide wheels are installed on the chain beam corresponding to the guide wheels. Through this refined design, high-precision control of the angle of the support plate is achieved, greatly enhancing the stability and safety of the billet lifting process. Specifically, the guide wheels at both ends of the pin shaft are closely matched with the guide grooves on the chain beam, enabling the support plate to enter a stable guiding state before dragging the billet. This design effectively offsets the influence of the billet's gravity on the angle of the support plate, ensuring that the support plate can maintain a horizontal or preset angle when lifting the billet, thereby preventing the risk of the billet slipping due to angle changes.

[0021] In addition, the cooperation between the guide wheel and the guide groove also plays a role in restricting the movement range of the support plate, avoiding excessive shaking or deviation of the support plate during lifting, and further improving the stability and accuracy of lifting. The application of this technical feature not only reduces the risk of equipment damage and production interruption but also improves the operating efficiency and output of the entire production line, providing strong technical support for the automated production of the steel industry.

[0022] Further preferably, a horizontal supporting plate 4 is horizontally installed on the vertical plates of the two L-shaped supporting plates. This technical feature provides more comprehensive and stable support for the steel billet by adding the horizontal supporting plate 4. The combination of the horizontal supporting plate and the vertical plates of the L-shaped supporting plate forms a closed or semi-closed supporting space, effectively preventing the side slip or falling of the steel billet during the lifting process. At the same time, the horizontal supporting plate also increases the supporting area, disperses the pressure of the steel billet on the supporting plate, and improves the bearing capacity and service life of the supporting plate.

[0023] Further preferably, the horizontal supporting plate is detachably installed on the upper end surface of the supporting plate. The detachable design enables the horizontal supporting plate 4 to be conveniently installed, disassembled and replaced, reducing the maintenance cost. When the horizontal supporting plate needs to be replaced due to wear or damage, there is no need to replace the entire supporting plate assembly, and only the horizontal supporting plate needs to be replaced. This design improves the flexibility and maintainability of the device, helping to reduce production interruptions and repair time.

[0024] Further preferably, a cushion block 5 is detachably installed on the lifting link adjacent to the upstream of the lifting plate assembly. The installation of the cushion block 5 provides additional support and buffering for the lifting plate assembly, helping to reduce the shaking and tilting caused by the change of chain tightness or uneven force on the supporting plate. The detachable design enables the cushion block to be flexibly adjusted or replaced according to actual needs to adapt to steel billets of different specifications and weights. This design improves the adaptability and stability of the device, helping to ensure the smooth lifting and accurate positioning of the steel billet.

[0025] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
