Description

Technical Field

[0001] This utility model relates to the field of material transfer boat technology, specifically a material transfer boat suitable for use in high-temperature furnaces. Background Technology

[0002] High-temperature furnaces (such as quenching furnaces and sintering furnaces) are widely used in metal heat treatment, ceramic sintering, and other fields, requiring uniform heating and rapid cooling of workpieces at high temperatures (800-1600℃). As the core tool for carrying workpieces, the transfer boat needs to operate stably in a high-temperature environment and ensure the quality of workpiece processing.

[0003] However, when the workpiece is large, the transfer boat cannot stably store it, making it prone to tipping or slipping due to vibration, inertia, or shift in center of gravity when it moves with the transfer boat. In addition, if the workpiece is forced onto the transfer boat, it may deform due to insufficient support or uneven treatment of suspended parts (such as inconsistent quenching hardness). Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a transfer boat suitable for use in high-temperature furnaces, which can be flexibly adjusted as needed.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transfer boat suitable for use in a high-temperature furnace, comprising a base plate, a U-shaped plate fixedly connected to the upper surface of the base plate, and a slider adapted to the internal slide rail of the high-temperature furnace fixedly connected to the lower surface of the base plate. Two grooves of the same size are provided on the left and right sides of the upper surface of the U-shaped plate, and fixed seats are detachably connected to the two grooves. Storage mechanisms are fixedly connected to the two fixed seats.

[0006] Furthermore, wear-resistant ceramic sheets are embedded in the contact surface between the slider and the slide rail inside the high-temperature furnace.

[0007] Furthermore, the fixing base includes a U-shaped locking block one and a U-shaped locking block two that match the groove, and a support plate is connected between the U-shaped locking block one and the U-shaped locking block two.

[0008] Furthermore, the storage mechanism includes two side plates fixedly connected between two support plates, a number of crossbars fixedly connected between the two support plates, and a number of longitudinal bars fixedly connected between the two side plates, with the crossbars and longitudinal bars fixed to each other.

[0009] Furthermore, each of the side plates has several through holes, and several reinforcing ribs are fixedly connected between the two side plates.

[0010] Furthermore, a threaded hole is provided between the two grooves, and a fixing component for fixing the fixing seat is threadedly connected to the threaded hole. The fixing component includes a hexagonal bolt threaded to the threaded hole, and a pressing plate is sleeved on the hexagonal bolt. The width of the pressing plate is greater than the distance between the two grooves.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This type of transfer boat, suitable for use in high-temperature furnaces, combines multiple transfer boats into one unit through a detachable connection structure, flexibly expanding the overall length to accommodate the storage needs of workpieces of different sizes. It ensures that the same batch of workpieces is completely supported within the boat assembly, avoiding storage instability caused by workpieces exceeding the limits of a single boat. The assembled boats form a continuous support platform, eliminating suspended areas of the workpieces and preventing the risk of tipping or slipping due to vibration, inertia, or center of gravity shift, thus ensuring transportation safety. The workpieces receive full support throughout the process, avoiding uneven contact of the quenching medium or differences in heat conduction caused by local suspension, ensuring consistency of key indicators such as hardness and microstructure.

[0019] 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.

[0020] Please see Figures 1 to 5A transfer boat suitable for use in a high-temperature furnace includes a base plate 1. A U-shaped plate 2 is fixedly connected to the upper surface of the base plate 1, and a slider 3 adapted to the slide rail inside the high-temperature furnace is fixedly connected to the lower surface of the base plate 1. Two grooves 4 of the same size are opened on the left and right sides of the upper surface of the U-shaped plate 2. Fixing seats are detachably connected to the two grooves 4, and storage is fixedly connected to the two fixing seats. A fixing component for fixing the fixing seat is threadedly connected to the threaded hole 5.

[0021] like Figures 1 to 5 As shown, the transfer boat in this utility model, suitable for use in high-temperature furnaces, extends its length by installing the fixing base into the grooves 4 on the two U-shaped plates 2. The storage mechanism supports and stores the workpieces. Multiple transfer boats can be combined into one unit via a detachable connection structure, flexibly expanding the overall length to accommodate workpieces of different sizes. This ensures that the same batch of workpieces is completely supported within the boat assembly, avoiding instability caused by workpieces exceeding the limits of a single boat. The combined boats form a continuous support platform, eliminating suspended areas and preventing tipping or slippage due to vibration, inertia, or center of gravity shift, ensuring safe transportation. The workpieces receive full support throughout the process, preventing uneven contact of the quenching medium or differences in heat conduction caused by localized suspension, ensuring consistency in key indicators such as hardness and microstructure. It should be noted that all the above-mentioned new structures are made of high-temperature resistant materials (withstanding temperatures ≥1600℃).

[0022] like Figure 3 As shown, wear-resistant ceramic sheets are embedded in the contact surface between the slider 3 and the slide rail inside the high-temperature furnace.

[0023] Specifically, wear-resistant ceramic sheets are embedded in the contact surface between slider 3 and the internal slide rail of the high-temperature furnace, which reduces wear and extends its service life. The wear-resistant ceramic sheets are fixed to the contact surface of slider 3 with a high-temperature adhesive and can withstand temperatures ≥1600℃.

[0024] like Figure 2 and Figure 4 As shown, the fixing base includes a U-shaped locking block 6 and a U-shaped locking block 7 that match the groove 4, and a support plate 8 is connected between the U-shaped locking block 6 and the U-shaped locking block 7.

[0025] Specifically, by inserting U-shaped card block 1 6 and U-shaped card block 2 7 into the grooves 4 on the two U-shaped plates 2 respectively, and by having the support plate 8 abut against the upper surface of the base plate 1, the initial installation of the fixing seat can be completed, thereby using the support plate 8 to support and limit the storage mechanism.

[0026] like Figure 2 and Figure 4As shown, the storage mechanism includes two side plates 9 fixedly connected between two support plates 8, a plurality of crossbars 10 fixedly connected between the two support plates 8, and a plurality of longitudinal bars 11 fixedly connected between the two side plates 9, with the crossbars 10 and the longitudinal bars 11 being fixed to each other.

[0027] Specifically, the side plate 9 abuts against the upper surface of the base plate 1, providing support. Several crossbars 10 and vertical bars 11 are used to store and support the workpieces, and workpieces of different sizes can be placed on the crossbars 10 and vertical bars 11.

[0028] like Figure 2 and Figure 4 As shown, each of the side plates 9 has several through holes 12, and several reinforcing ribs 13 are fixedly connected between the two side plates 9.

[0029] Specifically, the through hole 12 reduces the weight of the side plate 9 without affecting its supporting strength, while the reinforcing rib 13 further strengthens the crossbar 10 and the longitudinal bar 11 to support the workpiece and prevents the crossbar 10 and the longitudinal bar 11 from deforming under stress.

[0030] like Figure 5 As shown, a threaded hole 5 is provided between the two grooves 4, and a fixing component for fixing the fixing seat is threadedly connected to the threaded hole 5. The fixing component includes a hexagonal bolt 14 threadedly connected to the threaded hole 5, and a pressing plate 15 is sleeved on the hexagonal bolt 14. The width of the pressing plate 15 is greater than the distance between the two grooves 4.

[0031] Specifically, after the fixing seat is installed on the groove 4, the extrusion plate 15 is placed on the U-shaped plate 2, the central hole of the extrusion plate 15 is aligned with the threaded hole 5, and the hexagonal bolt 14 is threaded into the threaded hole 5. The hexagonal bolt 14 then extrudes the extrusion plate 15, thereby extruding the U-shaped block 6 or the U-shaped block 7 to limit the upper ends of the U-shaped block 6 and the U-shaped block 7, so that the U-shaped block 6 and the U-shaped block 7 cannot be removed from the groove 4, thus ensuring the strength of the overall structure. Furthermore, when multiple transfer boats are connected together, the extrusion plate 15 can simultaneously fix and limit the two fixing seats.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
