Description

Technical Field

[0001] This utility model belongs to the field of co-infiltration furnace repair and maintenance technology, specifically relating to a lifting frame for a lifting vacuum aluminum-silicon co-infiltration furnace. Background Technology

[0002] In the field of metal heat treatment, vacuum aluminosilicate co-infiltration technology is an important surface treatment process that can significantly improve the comprehensive properties of metal materials, such as wear resistance, corrosion resistance, and oxidation resistance. It is widely used in many high-end manufacturing industries such as aerospace, automobile manufacturing, and mechanical engineering. As the core equipment for implementing this process, the stability and reliability of the vacuum aluminosilicate co-infiltration furnace are directly related to the quality and effect of heat treatment. During the use of the vacuum aluminosilicate co-infiltration furnace, regular inspection and maintenance are the key links to ensure its normal operation, extend its service life, and guarantee the quality of treatment.

[0003] However, existing maintenance methods for vacuum aluminosilicate co-infiltration furnaces have many inconveniences. On the one hand, due to the large size and heavy weight of the furnace, maintenance requires lifting it to a suitable height so that operators can easily inspect, repair, and replace the furnace interior and its components. However, traditional lifting methods, such as using cranes, are not only cumbersome and require professional personnel, but the lifting process is also unstable, easily causing shaking and collisions to the furnace, which may damage the furnace structure or internal precision components, affecting the equipment's accuracy and service life. On the other hand, while some simple lifting devices can achieve a certain degree of lifting, they often suffer from poor synchronization. During the lifting process, the various support points cannot rise synchronously, resulting in uneven stress on the furnace, causing tilting or twisting. This not only brings great difficulties to maintenance work but may also further damage the equipment, increasing maintenance costs and downtime. Therefore, this utility model proposes a lifting frame for a lifting vacuum aluminosilicate co-infiltration furnace. Utility Model Content

[0004] The purpose of this invention is to provide a lifting frame for a lifting vacuum aluminum-silicon co-infiltration furnace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting frame for a lifting vacuum aluminum-silicon co-infiltration furnace, comprising...

[0006] The fixed frame is located at the top rear of the vacuum aluminum-silicon co-infiltration furnace; the T-shaped corner device is installed inside the fixed frame; the servo motor is installed on the top of the fixed frame and its output end is connected to the T-shaped corner device; two right-angle corner devices are set on the left and right sides of the fixed frame; and two screw jacks are set in front of the right-angle corner devices.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1 to 3This is the first embodiment of the present invention, which provides the following technical solution: a lifting frame for a lifting vacuum aluminum-silicon co-infiltration furnace, comprising...

[0025] The fixed frame 1 is located at the top rear of the vacuum aluminum-silicon co-infiltration furnace 9; the T-shaped corner device 3 is installed inside the fixed frame 1; the servo motor 2 is installed on the top of the fixed frame 1 and its output end is connected to the T-shaped corner device 3; the two right-angle corner devices 5 are set on the left and right sides of the fixed frame 1; and the two screw jacks 6 are set in front of the right-angle corner devices 5.

[0026] A connecting shaft 4 is connected between the right-angle corner 5 and the T-shaped corner 3, as well as between the right-angle corner 5 and the screw jack 6, to realize the power transmission between the T-shaped corner 3, the right-angle corner 5 and the screw jack 6. A connecting shaft 63 is connected between two adjacent screw jacks 6 to realize the power transmission between the two screw jacks 6 on the same side.

[0027] A bracket 7 is movably mounted on the support screw 61 at the bottom of the screw jack 6, and a nut seat that is threadedly connected to the support screw 61 is fixed on the inner side of the bracket 7. A support arm 8 that lifts the bottom of the vacuum aluminum-silicon co-infiltration furnace 9 is rotatably mounted on the top front end of the bracket 7.

[0028] In this embodiment, preferably, the fixed frame 1 and the right-angle turner 5 are both fixed to the external base by multiple bolts. Each screw jack 6 has a fixed seat 64 at its bottom, and the fixed seat 64 is also fixed to the external base by bolts. The fixed seat 64, the right-angle turner 5 and the fixed frame 1 are fixed on the same horizontal plane, so that the fixed frame 1, the right-angle turner 5 and the screw jack 6 of the lifting frame are stably fixed and supported.

[0029] In this embodiment, preferably, a bearing-supported seat 62 is provided directly below the screw jack 6 to support the bottom end of the supporting screw 61, and the bearing-supported seat 62 is fixed to the ground, which can effectively support the supporting screw 61, so that the supporting screw 61 can rotate smoothly when the screw jack 6 is running.

[0030] In this embodiment, preferably, a connecting rod 71 is connected between two adjacent brackets 7 to further ensure the synchronous stability of the two brackets 7 when they are raised and lowered.

[0031] In this embodiment, preferably, the front end of the support arm 8 is provided with an L-shaped positioning notch 81 corresponding to the bottom edge of the vacuum aluminum-silicon co-infiltration furnace 9, so that the front end of the support arm 8 can be adapted to the bottom edge of the vacuum aluminum-silicon co-infiltration furnace 9, ensuring positioning accuracy.

[0032] In summary, when the vacuum aluminosilicate co-infiltration furnace 9 is placed inside the lifting frame during actual use, the support arms 8 at the front ends of the four brackets 7 can be rotated to the bottom of the vacuum aluminosilicate co-infiltration furnace 9, so that the L-shaped positioning notch 81 at the front end of the support arm 8 matches the bottom edge of the vacuum aluminosilicate co-infiltration furnace 9. Thus, the vacuum aluminosilicate co-infiltration furnace 9 is stably supported and positioned by the four brackets 7 and the support arms 8. Then, by starting the servo motor 2, the servo motor 2 transmits power to the four screw jacks 6 through the T-shaped corner jack 3, connecting shaft 4, and right-angle corner jack 5, so that the four supporting screws 61 at the bottom of the four screw jacks 6 rotate synchronously. Thus, under the action of the nut seat inside the bracket 7, the four brackets 7 and the support arms 8 are driven to rise synchronously and smoothly, thereby achieving stable lifting of the vacuum aluminosilicate co-infiltration furnace 9.

[0033] It is worth noting that the servo motor 2, T-shaped angler 3, right-angle angler 5, and screw jack 6 in this embodiment are all mature products that can be directly purchased on the market (e.g., the servo motor 2 can be a Siemens 1FT6 series servo motor; the T-shaped angler 3 can be an HD17 T-type spiral bevel gear bevel gear 90-degree angler; the right-angle angler 5 can be an ARA0 series right-angle gearbox speed increaser steering gear; and the screw jack 6 can be an M series high-precision screw jack (e.g., M1605, M2510, etc.)). The structures of these devices are all existing technologies, and mature products can be directly purchased and put into use. Therefore, their structural principles will not be elaborated here.

[0034] Example 2

[0035] Please see Figures 1 to 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the top surface of the support arm 8 is also equipped with an anti-slip pad 82, and the anti-slip pad 82 is in contact with the vacuum aluminum-silicon co-infiltration furnace 9 by compression, which can further improve the stability of the support arm 8 when supporting the vacuum aluminum-silicon co-infiltration furnace 9. The multiple anti-slip grooves on the top of the anti-slip pad 82 can play an effective anti-slip role.

[0036] In this embodiment, preferably, the bottom surface of the anti-slip pad 82 is provided with a plurality of integrated T-shaped rubber clips 821, both of which are made of rubber material and will undergo elastic deformation when squeezed. The top surface of the support arm 8 is provided with a clip hole 83 for the T-shaped rubber clips 821 to pass through. The bottom end of the T-shaped rubber clip 821 passes through the clip hole 83 to the bottom of the support arm 8, so that the anti-slip pad 82 can be stably installed on the top surface of the support arm 8.

[0037] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
