Description

Technical Field

[0001] This utility model relates to the technical field of thermocouple switching devices, specifically to a thermocouple switching device with a vertical adjustment structure. Background Technology

[0002] Kilns are widely used in industrial production, such as glass kilns and steel heating furnaces. Their internal temperature distribution is complex, necessitating real-time monitoring of the heating, holding, and cooling processes using thermocouple switching devices. Thermocouple switching devices are key equipment in industrial temperature measurement systems, enabling the switching, selection, and transmission of multiple thermocouple signals. They allow for rapid switching between multiple thermocouple measuring points, allowing a single secondary instrument (such as a recorder, controller, or digital display) to measure or monitor multiple temperature points simultaneously, thereby reducing equipment costs and simplifying system wiring.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Common thermocouple switching devices are usually installed inside the kiln at a fixed height, so they can only measure the temperature at a single height. Since the temperature varies at different heights, the accuracy of temperature measurement is reduced. Utility Model Content

[0005] The purpose of this invention is to provide a thermocouple switching device with a vertical adjustment structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a thermocouple switching device with a vertical adjustment structure, comprising a mounting plate, a housing mounted on the bottom of the mounting plate, a first sliding groove formed at the middle of both ends of the housing, a second sliding groove formed at the middle of one side of the housing, a lifting assembly mounted on the bottom of the mounting plate inside the housing, and a device body formed on one side of the lifting assembly outside the housing.

[0007] The lifting assembly includes a fixed frame fixedly connected to one side of the bottom of the mounting plate and a connecting rod rotatably connected to the center of the bottom of the mounting plate. A servo motor is mounted on the lower inner surface of the mounting plate. The output shaft of the servo motor is connected to a main gear. A secondary gear meshes with the upper outer side of the main gear. The secondary gear is fixedly connected to the outside of the connecting rod. A limit block is fixedly connected to the bottom of the connecting rod. A threaded rod is fixedly connected to the bottom of the limit block. A threaded collar is threadedly connected to the outside of the threaded rod. A connecting block is fixedly connected to one side of the threaded collar. A mounting block is fixedly connected to one side of the connecting block. A first connecting frame is fixedly connected to both ends of the threaded collar. A first support rod is rotatably connected to the inner side of the first connecting frame. A second support rod is rotatably connected to the outer side of one end of the first support rod. A second connecting frame is rotatably connected to the outer side of one end of the second support rod. The top of the second connecting frame is fixedly connected to both ends of the bottom of the mounting plate.

[0008] The beneficial effects of this utility model are as follows: the lifting component enables the device body to move vertically, and during vertical movement, the first support rod and the second support rod slide inside the first slide groove, and the connecting block slides inside the second slide groove, making the lifting process more stable. This allows for the adjustment of the height of the device body, thereby enabling the measurement of temperatures at different heights inside the kiln, effectively improving the diversity and accuracy of temperature measurement.

[0009] To enable the installation of the mounting plate:

[0010] Further configuration: mounting holes are provided around the top of the mounting plate.

[0011] By adopting the above technical solution, workers can pass the fixing bolts through the mounting holes and then install them in the corresponding area, thereby ensuring the stability of the mounting plate after installation.

[0012] To enable the threaded rod to rotate:

[0013] Further configuration: the servo motor and the main gear form a rotating structure, and the main gear and the auxiliary gear form a meshing transmission structure.

[0014] By adopting the above technical solution, the output shaft of the servo motor can drive the main gear to rotate, thereby driving the secondary gear to rotate through meshing transmission, which in turn causes the connecting rod to rotate, and thus drives the threaded rod to rotate.

[0015] To enable the device body to be vertically raised and lowered:

[0016] The design further specifies that the inner dimensions of the first slide groove are consistent with the outer dimensions of the first and second support rods, and the inner dimensions of the second slide groove are consistent with the outer dimensions of the connecting block.

[0017] By adopting the above technical solution, when the threaded rod rotates, the threaded collar can move vertically through the limiting of the first sliding groove, the first support rod and the second support rod, and the limiting of the first sliding groove and the connecting rod. This allows the first support rod and the second support rod to slide inside the first sliding groove, while the connecting block slides inside the second sliding groove, thereby driving the device body to adjust its vertical position.

[0018] To achieve stability during the rotation of the threaded rod:

[0019] Further configuration: The bottom of the threaded rod is rotatably connected to the lower inner surface of the housing.

[0020] By adopting the above technical solution, the bottom of the threaded rod has a certain supporting effect, which can prevent swaying and thus increase stability.

[0021] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

A mounting block 5010 is fixedly connected to one side of the connecting block 509. A first connecting frame 5011 is fixedly connected to both outer ends of the threaded collar 508. A first support rod 5012 is rotatably connected to the inner side of the first connecting frame 5011. A second support rod 5013 is rotatably connected to the outer side of one end of the first support rod 5012. A second connecting frame 5014 is rotatably connected to the outer side of one end of the second support rod 5013.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, mounting holes are provided around the top of the mounting plate 1.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the servo motor 503 and the main gear 504 form a rotating structure, and the main gear 504 and the auxiliary gear 505 form a meshing transmission structure.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the inner dimensions of the first slide groove 3 are consistent with the outer dimensions of the first support rod 5012 and the second support rod 5013, and the inner dimensions of the second slide groove 4 are consistent with the outer dimensions of the connecting block 509.

[0032] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the threaded rod 507 is rotatably connected to the lower inner surface of the housing 2.

[0033] The computer software involved in the servo motor and other hardware carriers in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0034] Therefore, the "servo motor" and the like mentioned in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of the automatic dipping machine of this application, so as to solve the corresponding technical problems to be solved by this application.

[0035] The thermocouple switching device with a vertical adjustment structure operates as follows:

[0036] First, pass the fixing bolts through the mounting holes of the mounting plate 1, and then install it in the corresponding area. This will activate the device body 6 to perform temperature detection. When it is necessary to measure the temperature at different heights, the servo motor 503 (model: 90ST-X02430-EX) can be activated. The output shaft of the servo motor 503 will drive the main gear 504 to rotate, which in turn drives the secondary gear 505 to rotate through meshing transmission. This causes the connecting rod 502 to rotate, which in turn drives the threaded rod 507 to rotate, thereby causing the threaded rod to rotate. The collar 508 moves vertically under the limiting action of the first connecting frame 5011, the first support rod 5012, the second support rod 5013, and the second connecting frame 5014 at both ends. This causes a change in the angle between the first support rod 5012 and the second support rod 5013, and the first support rod 5012 and the second support rod 5013 slide inside the first slide groove 3. At the same time, the connecting block 509 also slides inside the second slide groove 4, thereby driving the device body 6 to adjust its height, so that the temperature at different heights can be measured.
