[0039] The nitriding process is an important process that uses catalyst nitrides to produce a nitride film on the surface of materials (including metals) when exposed to a certain temperature and pressure environment. This can greatly improve the performance and life of the metal surface. The nitriding process is widely used in many products in daily life. Due to its good rust resistance, wear resistance and corrosion resistance, it is widely used in food processing, petrochemical, medical and health, precision instruments, automobile manufacturing and other industries.

[0040] Nitriding furnace is a portable device mainly used for nitriding metal surface, which can apply a nitrided surface layer to the metal surface. Nitriding furnace is usually used for nitriding of various metal materials, including various metal alloys, sheet metal parts, carbon steel parts, free-cutting metals and non-metallic materials. Nitriding furnace adopts controllable temperature design, with timing and constant temperature functions. Nitriding treatment process can be completed automatically, which can effectively reduce labor intensity and ensure treatment quality.

[0041] In the existing maintenance technology, the maintenance of nitriding furnaces involves many problems. Due to the compact equipment layout, small maintenance space, heavy furnace tank weight and other issues, it is very difficult to dismantle the tank for maintenance on the complete production line. The maintenance passage is narrow, there are various pipelines and lines above the equipment, and large equipment such as cranes and forklifts cannot be used.

[0042] In order to solve the above problems, the present invention proposes a quick maintenance tool and maintenance device for a nitriding furnace, aiming to provide a quick maintenance tool and maintenance device for a nitriding furnace that is easy to disassemble and assemble the furnace tank and the nitriding furnace. Figure 1 to Figure 2 The present invention is a schematic structural diagram of an embodiment of a rapid maintenance tool for a nitriding furnace provided by the present invention.

[0043] Please refer to Figure 1 to Figure 2 In one embodiment of the present invention, the quick maintenance tool 100 for a nitriding furnace comprises a frame 1, a guide rail 2 and a support frame 3; two frames 1 are provided, which are respectively fixed on the ground of two furnace cavity outlets arranged opposite to each other; one end of the guide rail 2 is fixed on one of the frames 1, and the other end extends into the furnace cavity from the furnace cavity outlet, and extends from the furnace cavity outlet from the other end, and is fixed on the other frame 1; two support frames 3 are provided, which are respectively fixed on the furnace pots at the two furnace cavity outlets; wherein, the support frame 3 moves along the extension direction of the guide rail 2 to drive the furnace pot to be taken out of the furnace cavity.

[0044] The technical solution of the present invention adopts two frames 1 respectively fixed on the ground of two furnace chamber outlets arranged opposite to each other, the guide rail 2 is arranged between the two frames 1, and the furnace pot is fixed by the support frame 3, and the support frame 3 is driven to move along the extension direction of the guide rail 2, so that the furnace pot is removed from the furnace chamber, thereby greatly reducing the difficulty of disassembling and assembling the furnace pot relative to the nitriding furnace, thereby reducing maintenance investment and further improving maintenance efficiency.

[0045] For further information, please refer to Figure 1 and Figure 2, the quick maintenance tool 100 for the nitriding furnace further includes a roller mechanism 4, which is convexly arranged on the lower side of the support frame 3 to roll with the guide rail 2. It can be understood that in some embodiments, the support frame 3 can be provided with a groove corresponding to the guide rail 2, so that the support frame 3 can slide with the guide rail 2 to make the furnace pot slide out of the furnace cavity, but due to the high difficulty and high cost of the processing technology of the groove, and because the furnace pot has a large weight, even if the sliding friction generated by sliding on the guide rail 2 is also large, it is not easy to slide the furnace pot out of the furnace cavity; therefore, in other embodiments, the quick maintenance tool 100 for the nitriding furnace further includes the roller mechanism 4, which is convexly arranged on the lower side of the support frame 3 to roll with the guide rail 2. It is well known that the rolling friction is much smaller than the sliding friction, so that the roller mechanism 4 can be used to further roll the furnace pot out of the furnace cavity more easily, thereby further reducing the labor intensity.

[0046] Further, the roller mechanism 4 is provided with two, and is respectively provided in a one-to-one correspondence with the two support frames 3. It can be understood that, in some embodiments, the roller mechanism 4 is provided with one, and is provided at the other end of the guide rail 2, while the other end of the guide rail 2 is not provided with the roller mechanism, and the furnace pot can also be removed from the furnace cavity by sliding the support frame 3 relative to the guide rail 2, but this method is difficult to reinstall, and because the furnace pot has a large deadweight, the guide rail 2 is greatly worn when the support frame 3 slides, so in other embodiments, the roller mechanism 4 is provided with two, and is respectively provided in a one-to-one correspondence with the two support frames 3, so that both ends of the furnace pot have the roller mechanism 4, and then the support frame 3 can adopt the rolling friction method relative to the guide rail 2, and it is very easy to remove or reinstall the furnace pot relative to the furnace cavity, thereby greatly reducing the intensity of manual operation.

[0047] For further information, please refer to Figure 2The roller mechanism 4 includes two support blocks 41, a rolling shaft 42 and a rolling member 43; the two support blocks 41 are protruded from the bottom end of the support frame 3 and are arranged opposite to each other along the width direction of the guide rail 2; the two ends of the rolling shaft 42 are rotatably connected to the two support blocks 41 respectively; the rolling member 43 is sleeved on the rolling shaft 42, and the circumferential side of the rolling member 43 is in rolling cooperation with the guide rail 2. It can be understood that in order to remove the furnace pot relative to the furnace cavity using the roller mechanism 4, specifically, the roller mechanism 4 includes the two support blocks 41, the rolling shaft 42 and the rolling member 43, wherein the two support blocks 41 are protruded from the bottom end of the support frame 3 to form a mounting base for the rolling member 43, and are relatively arranged along the width direction of the guide rail 2, and the two ends of the rolling shaft 42 are rotatably connected to the two support blocks 41 respectively, and the rolling member 43 is sleeved on the rolling shaft 42, and the circumferential side of the rolling member 43 is in rolling cooperation with the guide rail 2, thereby, the roller mechanism 4 can roll the furnace pot out of the furnace cavity.

[0048] For further information, please refer to Figure 2 , the rolling element 43 includes a rolling bearing 431. It can be understood that, in some embodiments, the rolling elements 43 are only some rollers. Since the weight of the furnace tank is very large, there will be a large friction between the rollers and the rolling shaft 42, which will cause the rollers and the rolling shaft 42 to be easily sintered due to excessive friction, thereby affecting the disassembly of the furnace tank. In order to further reduce the rolling friction, the rolling element 43 includes the rolling bearing 431, which can effectively distribute the friction and the weight of the furnace tank on each roller, and then relative to the rollers, the rolling bearing 431 is more durable and not easy to be damaged, thereby improving the reliability of the rapid maintenance tool 100 for the nitriding furnace.

[0049] For further information, please refer to Figure 2 The roller mechanism 4 further includes a shaft sleeve 44, two of which are provided, which are sleeved on the rolling shaft 42 and are respectively located at the two ends of the rolling member 43. It can be understood that friction is everywhere, and when the rolling member 43 rolls, friction will also occur between the two end surfaces of the rolling member 43 along its length direction and the support block 41, thereby causing wear of the rolling member 43 and the support block 41. Therefore, in order to avoid wear, the roller mechanism 4 further includes the shaft sleeve 44, two of which are provided, which are sleeved on the rolling shaft 42 and are respectively located at the two ends of the rolling member 43. Then, through the protection of the shaft sleeve 44, the mutual wear between the rolling member 43 and the support block 41 is avoided, and at the same time, the quick maintenance tool 100 for the nitriding furnace is made more reliable and safe.

[0050] For further information, please refer to Figure 2 , the support block 41 continues to extend from the rolling shaft 42 to form a retaining edge 411. It can be understood that in order to ensure that the rolling element 43 always maintains rolling cooperation with the guide rail 2 during the rolling of the furnace pot, and does not allow the rolling element 43 to derail relative to the guide rail 2, the support block 41 continues to extend from the rolling shaft 42 to form the retaining edge 411, and the two retaining edges 411 formed by the two support blocks 41 are clamped on both sides of the guide rail 2. During the rolling of the rolling element 43, the retaining edge 411 clamps the guide rail 2, so that the rolling element 43 always maintains rolling cooperation with the guide rail 2, thereby avoiding the possibility of the rolling element 43 derailing, and further ensuring the reliability of the use of the rapid maintenance tool 100 for the nitriding furnace.

[0051] In addition, please refer to Figure 1 The quick maintenance tool 100 for the nitriding furnace also includes a height adjustment mechanism 5, which is arranged on the bottom foot 11 of the frame 1, and is used to adjust the height of the furnace pot. It can be understood that in order to facilitate the furnace pot to be rolled out from the furnace cavity, the furnace pot must have a suitable position relative to the outlet of the furnace cavity. Since the furnace pot has a large deadweight, when the furnace pot is disassembled, the furnace pot will sink a little relative to the outlet of the furnace cavity, thereby making it impossible to remove the furnace pot. Therefore, the quick maintenance tool 100 for the nitriding furnace also includes the height adjustment mechanism 5, which is arranged on the bottom foot 11 of the frame 1, so as to facilitate the adjustment of the height of the furnace pot, so that the furnace pot is aligned with the outlet of the furnace cavity, so as to facilitate the subsequent removal work.

[0052] For further information, please refer to Figure 1 The height adjustment mechanism 5 includes a stud 51 and an operation block 52; the stud 51 extends in the up-down direction, and a thread is arranged around the side ring thereof to be threadedly connected with the foot 11; the operation block 52 is arranged at one end of the stud 51 close to the ground, and is used to operate the stud 51 to rotate. It can be understood that in order to facilitate the adjustment of the height of the furnace pot, the furnace pot is aligned with the furnace cavity outlet, so as to facilitate the subsequent disassembly work, the height adjustment mechanism 5 includes the stud 51 and the operation block 52, wherein the stud 51 extends in the up-down direction, and a thread is arranged around the side ring thereof to be threadedly connected with the foot 11; the operation block 52 is arranged at one end of the stud 51 close to the ground, and is used to operate the stud 51 to rotate, and by rotating the operation block 52, the foot 11 is adjusted to any height of the bolt in the up-down direction, and the height between the foot 11 and the operation block 52 is the height at which the support frame 3 can lift the furnace pot.

[0053] The present invention further proposes a maintenance device, which includes the quick maintenance tool 100 for the nitriding furnace. The specific structure of the quick maintenance tool 100 for the nitriding furnace refers to the above-mentioned embodiment. Since the maintenance device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0054] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
