Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, and in particular to a heat treatment furnace sample sampling device and method. Background Art

[0002] The laboratory box-type resistance high-temperature furnace is a device that can sinter, bake, anneal, quench and other processes on materials in an oxygen environment. It adopts a side-opening door and can move 180 degrees horizontally. The maximum temperature can reach 1700℃. It is widely used in ceramics, metallurgy, chemical industry, machinery, high-temperature testing, material processing and other fields. Before actual production, the steel material can be subjected to laboratory heat treatment to obtain laboratory data, which has a certain guiding role in production.

[0003] When heat treating steel plates, when the treated steel is required to undergo tensile, impact and other performance tests, it is necessary to ensure that the overall performance of the steel is consistent, which requires the size of the steel to be large enough.

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1, as Figures 1 to 7 As shown, this embodiment proposes a heat treatment furnace sample sampling device, including a carrier frame 1, and also includes rollers 2, a support assembly, a mounting frame 3, a sample taking and placing assembly, a sample placing assembly and a lever assembly. Four rollers 2 are symmetrically arranged at the bottom of the carrier frame 1, and the support assembly is installed on the top of the carrier frame 1 for support. The support assembly includes a bracket 4, a support frame 5 and an electric jack 6. The bracket 4 is fixedly installed on the top of the carrier frame 1, the support frame 5 is fixedly installed on the top of the bracket 4, the support frame 5 is slidably installed inside the mounting frame 3, and an electric jack 6 is fixedly installed inside the support frame 5, and the output end of the electric jack 6 is fixedly connected to the inner top wall of the mounting frame 3.

[0023] Specifically, when taking and placing samples in the heat treatment furnace, the sample to be processed is first placed on the sample placement assembly, at which time the electric jack 6 is in an extended state, and then the position of the sample placement assembly is adjusted through the setting of the lever assembly, the sample on the sample placement assembly is lifted up, and then the carrier frame 1 is pushed to move, and at this time the roller 2 rotates until it moves to the position of the heat treatment furnace, the roller 2 is locked, the heat treatment furnace is opened, the position of the sample placement assembly is adjusted through the lever assembly, and then the electric jack 6 is retracted, and the mounting frame 3 is pushed to slide on the support frame 5 until the mounting frame 3 is moved to the position of the heat treatment furnace. The sample placement assembly and the sample are placed together inside the heat treatment furnace. When the sample placement assembly is separated from the sample placement assembly, the roller 2 is unlocked, and then the carrier frame 1 is retracted. Then, the sample is started for heat treatment. When sampling is required, the sample placement assembly is first moved to the bottom of the sample placement assembly. At this time, the electric jack 6 is in a retracted state. At this time, the electric jack 6 is started, and the electric jack 6 pushes the mounting frame 3 to move upward on the support frame 5 until the sample placement assembly and the sample placement assembly are connected. The sample can be moved out through the cooperation of the lever assembly.

[0024] like Figure 3 , Figure 4 As shown, the mounting frame 3 is installed on the top of the supporting assembly, and a sample taking and placing assembly is installed on the mounting frame 3 for taking and placing samples. The sample taking and placing assembly includes a swing rod 7 and a sampling rack 8. Two swing rods 7 are symmetrically and rotatably installed on one side of the mounting frame 3. The two swing rods 7 are of equal length. The sampling rack 8 is rotatably connected to the two swing rods 7 respectively, and also includes a support rod 9. Two support rods 9 are symmetrically and rotatably installed on one side of the mounting frame 3. The two support rods 9 are located at the lower part of the two swing rods 7. The two support rods 9 are of equal length, wherein the two support rods 9 are both rotatably connected to the sampling rack 8, the support rod 9 is arranged parallel to the swing rod 7, and the length of the support rod 9 is equal to the length of the swing rod 7.

[0025] Specifically, when sampling, the sampling rack 8 is first moved to the bottom of the sample placement bucket 13. When the mounting frame 3 moves upward on the support frame 5, the sampling rack 8 can be docked with the plug-in frame 11, and the sample placement bucket 13 can be taken out. When adjusting the height position of the sample placement bucket 13, it will be adjusted by swinging the swing rod 7. During the swinging of the swing rod 7, under the restriction of the sampling rack 8 and the mounting frame 3, the support rod 9 swings synchronously, and during the swinging process, the relative position of the support rod 9 and the swing rod 7 always remains parallel, thereby ensuring that the sample placement bucket 13 always maintains a stable movement, reducing the problem of the sample tilting in the sample placement bucket 13.

[0026] like Figure 4As shown, the sample placement assembly is installed at one end of the sample placement assembly away from the mounting frame 3, and is used to carry the sample. The sample placement assembly includes a plug-in block 10, a plug-in frame 11 and a sampling part. Four plug-in blocks 10 are symmetrically arranged on one side of the sampling frame 8 away from the support rod 9, and two adjacent plug-in blocks 10 are symmetrically arranged. Two plug-in frames 11 are symmetrically arranged on the upper part of the sampling frame 8, and a sampling part is installed between the two plug-in frames 11 for placing the sample.

[0027] Specifically, during the sampling process, when the sampling rack 8 is moved to the lower part of the plug-in rack 11 on both sides of the sample placement bucket 13, the plug-in block 10 on the upper part of the sampling rack 8 enters the plug-in slot 12 opened at the lower part of the plug-in slot 12, and the sample placement bucket 13 can be taken out through the setting of the plug-in rack 11.

[0028] The above, such as Figure 5 As shown, the sampling part includes a plug-in slot 12 and a sample placement bucket 13. Two plug-in slots 12 are symmetrically opened at the bottom of the two plug-in racks 11. The plug-in slots 12 are adapted to the plug-in blocks 10. The sample placement bucket 13 is fixedly installed between the two plug-in racks 11.

[0029] Specifically, by Figure 4 as well as Figure 5 It can be seen that the adjacent sides of the two plug-in slots 12 in the plug-in rack 11 are set as inclined surfaces, so that the two plug-in blocks 10 on both sides of the plug-in rack 11 can enter the plug-in slots 12 more easily, and the setting of the inclined surfaces can also play a role in guiding the position of the plug-in blocks 10, ensuring stability during the picking and placing process.

[0030] like Figure 6 As shown, the lever assembly is installed on the top of the mounting frame 3, and is used to push the sample placement assembly to swing. The lever assembly includes a support shaft 14, a T-shaped lever 15, a connecting portion and a hand-held portion. The support shaft 14 is rotatably installed on the top of the mounting frame 3, and the T-shaped lever 15 is fixedly installed on the support shaft 14. The connecting portion is installed between the two swing rods 7 and is used to connect the T-shaped lever 15. The hand-held portion is installed on the side of the T-shaped lever 15 away from the sample placement bucket 13, and is used to push the T-shaped lever 15.

[0031] Specifically, when adjusting the swing position of the swing rod 7, the operator first holds the hand-held part and adjusts the relative position of the hand-held part and the T-shaped lever 15 to ensure that the distance from the position where the operator holds the hand-held part to the support shaft 14 is greater than the distance from the connecting part to the support shaft 14, which is convenient for saving effort. Then, the position of the T-shaped lever 15 is adjusted by the hand-held part. At this time, the T-shaped lever 15 drives the support shaft 14 to rotate on the top of the mounting frame 3, and the swing rod 7 can be swung through the setting of the connecting part.

[0032] The above, such as Figure 6As shown, the connection part includes a connection frame 16 and a sliding frame 17 . The connection frame 16 is fixedly installed between the two swing rods 7 . The sliding frame 17 is slidably installed on the connection frame 16 . The top of the sliding frame 17 is rotatably connected to the T-shaped lever 15 .

[0033] Specifically, when the T-shaped lever 15 swings, the T-shaped lever 15 will drive the sliding frame 17 to swing with the axial position of the support shaft 14 as the center, thereby driving the connecting frame 16 to swing. At this time, relative sliding occurs between the connecting frame 16 and the sliding frame 17, which can drive the swing rod 7 to swing.

[0034] The above, such as Figure 7 As shown, the handheld part includes a handheld sliding frame 18, a mounting hole 19, a positioning hole 20 and a positioning bolt 21. The handheld sliding frame 18 is slidably mounted on the side of the T-shaped lever 15 away from the sample placement bucket 13. The mounting holes 19 are equidistantly opened at one end of the bottom of the handheld sliding frame 18 close to the sliding frame 17. A plurality of positioning holes 20 are equidistantly opened at one side of the bottom of the T-shaped lever 15 away from the sample placement bucket 13. The plurality of positioning holes 20 are all adapted to the mounting holes 19. The positioning bolts 21 are fixedly installed in the mounting holes 19 and the positioning holes 20.

[0035] Specifically, when adjusting the swing position of the swing rod 7, the operator first holds the hand-held sliding frame 18 to slide the hand-held sliding frame 18 on the T-shaped lever 15. When the hand-held sliding frame 18 is adjusted to a suitable position, the mounting hole 19 on the hand-held sliding frame 18 corresponds to a positioning hole 20 on the T-shaped lever 15. The positioning bolt 21 is passed through the mounting hole 19 and the positioning hole 20, and the positioning bolt 21 is fixed. The position of the hand-held sliding frame 18 on the T-shaped lever 15 can be fixed, which is convenient and labor-saving.

[0036] To sum up, after the heat treatment of the sample is completed, the sample needs to be taken out. At this time, the position of the T-shaped lever 15 is adjusted first. Before adjusting the swing position of the swing rod 7, the operator first holds the hand-held sliding frame 18 to make the hand-held sliding frame 18 slide on the T-shaped lever 15. When the hand-held sliding frame 18 is adjusted to a suitable position, the mounting hole 19 on the hand-held sliding frame 18 corresponds to a certain positioning hole 20 on the T-shaped lever 15. The positioning bolt 21 is passed through the mounting hole 19 and the positioning hole 20, and the positioning bolt 21 is fixed to fix the position of the hand-held sliding frame 18 on the T-shaped lever 15. Ensure that the distance from the position where the operator holds the hand-held sliding frame 18 to the support shaft 14 is greater than the distance from the sliding frame 17 to the support shaft 14, which is convenient for saving effort. Then push the carrier frame 1 to move. At this time, the roller 2 rotates until it moves to the position of the heat treatment furnace, and then open the heat treatment furnace.

[0037] Then, the position of the T-shaped lever 15 is adjusted by holding the sliding frame 18. At this time, the T-shaped lever 15 drives the support shaft 14 to swing on the top of the mounting frame 3. At this time, the T-shaped lever 15 will drive the sliding frame 17 to swing with the axial position of the support shaft 14 as the center, thereby driving the connecting frame 16 to swing. At this time, relative sliding occurs between the connecting frame 16 and the sliding frame 17, which can drive the swing rod 7 to swing. During the swinging of the swing rod 7, under the restriction of the sampling frame 8 and the mounting frame 3, the support rod 9 swings synchronously. When the height position of the sampling frame 8 is lower than the position of the plug-in frames 11 on both sides of the sample placement bucket, the sampling frame 8 is moved to the lower part of the plug-in frames 11 on both sides of the sample placement bucket 13, and the roller 2 can be locked.

[0038] At this time, the electric jack 6 is in a retracted state. At this time, the electric jack 6 is started, and the electric jack 6 pushes the mounting frame 3 to move upward on the supporting frame 5. At this time, the plug-in block 10 on the upper part of the sampling frame 8 enters the plug-in slot 12 opened at the lower part of the plug-in slot 12. The sample placement bucket 13 can be connected to the sampling frame 8 through the setting of the plug-in frame 11. Since the adjacent sides of the two plug-in slots 12 in the plug-in frame 11 are set as inclined surfaces, the two plug-in blocks 10 on both sides of the plug-in frame 11 are easier to enter the plug-in slots 12, and the setting of the inclined surface can also play a role in guiding the position of the plug-in block 10, thereby ensuring stability during the picking and placing process.

[0039] Then, by setting the T-shaped lever 15, the position of the swing rod 7 is adjusted to take out the sample placement bucket, and during the swinging process of the swing rod 7, the relative positions of the support rod 9 and the swing rod 7 are always kept parallel, thereby ensuring that the sample placement bucket 13 always maintains stable movement, reducing the problem of the sample tilting in the sample placement bucket 13, and then release the lock of the roller 2 to move the sample out.

[0040] Embodiment 2: Based on a heat treatment furnace sample sampling device, this embodiment 2 also proposes a heat treatment furnace sample sampling method, comprising the following steps: The first step is to adjust the position of the T-shaped lever 15 , and the operator holds the hand-held sliding frame 18 to slide the hand-held sliding frame 18 on the T-shaped lever 15 .

[0041] The second step is positioning. When the handheld sliding frame 18 is adjusted to a suitable position, the mounting hole 19 on the handheld sliding frame 18 corresponds to a positioning hole 20 on the T-shaped lever 15. The positioning bolt 21 is passed through the mounting hole 19 and the positioning hole 20. The positioning bolt 21 is fixed to fix the position of the handheld sliding frame 18 on the T-shaped lever 15, ensuring that the distance from the position where the operator holds the handheld sliding frame to the support shaft 14 is greater than the distance from the sliding frame 17 to the support shaft 14, which is convenient for saving effort.

[0042] The third step is to open the heat treatment furnace and push the carrier frame 1 to move. At this time, the roller 2 rotates until it moves to the position of the heat treatment furnace, and then open the heat treatment furnace.

[0043] The fourth step is swinging. The position of the T-shaped lever 15 is adjusted by holding the sliding frame 18. At this time, the T-shaped lever 15 drives the supporting shaft 14 to swing on the top of the mounting frame 3.

[0044] The fifth step is to drive the T-shaped lever 15 to drive the sliding frame 17 to swing with the axial position of the supporting shaft 14 as the center, thereby driving the connecting frame 16 to swing, and at this time, relative sliding occurs between the connecting frame 16 and the sliding frame 17.

[0045] The sixth step is to lock and drive the swing rod 7 to swing. During the swinging process of the swing rod 7, under the restriction of the sampling rack 8 and the mounting rack 3, the support rod 9 swings synchronously. When the height position of the sampling rack 8 is lower than the position of the plug-in rack 11 on both sides of the sample placement bucket, the sampling rack 8 is moved to the lower part of the plug-in rack 11 on both sides of the sample placement bucket 13, and the roller 2 can be locked.

[0046] The seventh step is to connect and start the electric jack 6. The electric jack 6 pushes the mounting frame 3 to move upward on the supporting frame 5. At this time, the plug-in block 10 on the upper part of the sampling frame 8 enters the plug-in slot 12 opened at the lower part of the plug-in slot 12. The sample placement bucket 13 can be connected to the sampling frame 8 through the setting of the plug-in frame 11. Since the adjacent sides of the two plug-in slots 12 in the plug-in frame 11 are set as inclined surfaces, the two plug-in blocks 10 on both sides of the plug-in frame 11 are easier to enter the plug-in slots 12, and the setting of the inclined surface can also play a role in guiding the position of the plug-in block 10, thereby ensuring stability during the picking and placing process.

[0047] The eighth step is to take samples, and then adjust the position of the swing rod 7 through the setting of the T-shaped lever 15, so as to take out the sample placement bucket, and during the swinging process of the swing rod 7, the relative positions of the support rod 9 and the swing rod 7 are always kept parallel, so as to ensure that the sample placement bucket 13 always maintains stable movement, reducing the problem of the sample tilting in the sample placement bucket 13, and then release the lock of the roller 2 to move the sample out.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
