Description

Technical Field

[0001] This utility model belongs to the field of glass tempering technology, specifically relating to a tooling for adjusting thermocouples in a continuous furnace. Background Technology

[0002] Continuous furnaces, due to their long length, often employ a multi-section assembly method, resulting in a significant workload and high intensity during installation. This is especially true for the numerous thermocouples in the lower furnace section, as their height greatly affects the accuracy of temperature measurement. Therefore, during continuous furnace installation, the height of each thermocouple must be adjusted to be uniform. Currently, the adjustment method involves one installer at the bottom of the furnace loosening the thermocouple fixing clips, while another installer inside the furnace uses a ruler to adjust each thermocouple to the appropriate height. The lower installer then tightens the fixing clips, and this process is repeated to adjust each thermocouple to the same height. However, continuous furnaces have a large number of thermocouples, resulting in a heavy workload. Furthermore, the confined space at the furnace bottom makes operation difficult, often requiring a change of personnel after adjusting a certain number of thermocouples, leading to extremely low adjustment efficiency. Utility Model Content

[0003] The purpose of this invention is to solve the problems existing in the prior art and provide a tooling for adjusting thermocouples in a continuous furnace. This device can improve the efficiency of thermocouple installation and adjustment, while reducing the labor intensity of installers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a tooling for adjusting thermocouples in a continuous furnace, comprising a support, a crossbeam, a hanging screw, and a base plate; the base plate is arranged parallel to the crossbeam, and the end face of the base plate facing away from the crossbeam is a reference plane; the support is arranged at both ends of the crossbeam and connected to it; the head end of the hanging screw is detachably connected to the crossbeam, and the tail end of the hanging screw is connected to the base plate; the distance between the base plate and the crossbeam is adjustable.

[0005] As a preferred embodiment, the head end of the support is provided with an external threaded head I, which is connected to the crossbeam via a locking member I.

[0006] As a preferred embodiment, the locking component includes an upper nut I and a lower nut I, which are located on the upper and lower sides of the crossbeam, respectively.

[0007] As a preferred embodiment, the head end of the hanging screw is provided with an external threaded head II, which is connected to the crossbeam via a locking member II.

[0008] As a preferred embodiment, the locking component II includes an upper nut II and a lower nut II, which are located on the upper and lower sides of the crossbeam, respectively.

[0009] As a preferred embodiment, the tail end of the support is provided with a support member, the support member having a U-shaped groove, the U-shaped groove being used to contact the outer frame plate support on both sides of the furnace body.

[0010] As a preferred embodiment, the cross-section of the beam is U-shaped.

[0011] As a preferred embodiment, the base plate has flanges formed on both sides along its length, and the flanges are formed by bending the base plate towards the crossbeam from opposite sides.

[0012] As a preferred embodiment, the length of the crossbeam is greater than the length of the base plate.

[0013] Beneficial effects

[0014] This solution features a specially designed adjustment fixture for facilitating the standardization of thermocouple element height. This fixture comprises a support, crossbeam, hanging screws, and a base plate. By placing this fixture across the lower furnace body, the process involves first adjusting the crossbeam to the appropriate height while ensuring it is level. Next, the locking mechanism is adjusted, and the base plate is adjusted to the appropriate height, with minor adjustments to ensure it remains level. Then, the thermocouple height is adjusted to ensure the top of the thermocouple contacts the reference plane on the lower surface of the base plate. Finally, the thermocouple is secured with fixing clips. This fixture allows for the adjustment of an entire row of thermocouples in a continuous furnace at once, and it only requires one adjustment for continuous use. It eliminates the need to measure the installation height of each individual thermocouple element (existing techniques require workers to measure the installation height of each element individually, which is labor-intensive, inefficient, and prone to measurement and installation errors). This fixture significantly improves work efficiency, reduces labor intensity, saves installation costs, and achieves precise standardization of thermocouple installation height.

[0023] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0024] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "a," "an," or "the," and similar words used in this utility model patent application specification and claims do not express a quantity limitation, but rather indicate the presence of at least one. Terms such as "comprising" or "including" indicate that the elements or objects preceding "comprising" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.

[0025] As shown in the figure, this embodiment provides a fixture for adjusting thermocouples in a continuous furnace, including a support 1, a crossbeam 2, a hanging screw 3, and a base plate 4. The support 1 is located at both ends of the crossbeam 2 and is perpendicular to the crossbeam 2. The base plate 4 is parallel to the crossbeam 2 and located below the crossbeam 2. (For ease of description, this solution is referred to as...) Figure 2 The middle crossbeam 2 is the top of the tooling), and the plane of the base plate 4 facing away from the crossbeam 2 is the reference plane 42, combined with Figure 4 In the usage diagram, reference plane 42 is the lower surface of base plate 4. Support 1 is set at both ends of cross beam 2 and connected to it. The head end of the hanging screw 3 is detachably connected to cross beam 2, and the tail end of the hanging screw 3 is fixedly or integrally connected to base plate 4. The distance between base plate 4 and cross beam 2 is adjustable.

[0026] In this design, to achieve height adjustment of the crossbeam 2, the head end of the support 1 is equipped with an external threaded head I11, which is connected to the crossbeam 2 via a locking component I5. The crossbeam 2 has mounting holes, and a through-hole component 21 is fixedly installed at each mounting hole. The through-hole component 21 is a sleeve structure, through which the external threaded head I11 passes. Locking components I5 are installed and screwed onto both the upper and lower sides of the mounting hole, thus achieving a fixed connection between the support 1 and the crossbeam 2. The tail end of the support 1 is equipped with a support component 12 with a U-shaped groove 121. The U-shaped groove 121 serves to contact the outer frame plate 71 of the furnace body. The U-shaped groove 121 matches the outer frame plate 71, and its bottom is flat, matching the thickness of the outer frame plate 71 to ensure support stability. The locking component I5 includes an upper nut I51 and a lower nut I52, located on the upper and lower sides of the crossbeam 2 fixing plate, respectively. The upper nut I51 is located in the groove above the crossbeam 2, and the lower nut I52 is located on the bottom surface of the crossbeam 2. By adjusting the fixed position of the external thread head I11 of the support 1 and locking the upper nut I51 and the lower nut I52, the height and level of the crossbeam 2 can be adjusted.

[0027] In this embodiment, to achieve height adjustment of the base plate 4, the head end of the hanging screw 3 is provided with an external threaded head II 31. The external threaded head II 31 is connected to the crossbeam 2 via a locking member II 6. The external threaded head II 31 passes through the through hole 21 near the middle of the crossbeam 2, and the locking member II 6 is provided and screwed on both the upper and lower sides of the through hole 21, thereby achieving a fixed connection between the hanging screw 3 and the crossbeam 2. By adjusting the fixed position of the external threaded head II 31, the height and level of the base plate 4 can be adjusted. The locking member II 6 includes an upper nut II 61 and a lower nut II 62, which are located on the upper and lower sides of the fixing plate of the crossbeam 2, respectively. The upper nut II 61 is located in the groove above the crossbeam 2, and the lower nut II 62 is located on the bottom surface of the crossbeam 2. By adjusting the fixed position of the external threaded head II 31 of the hanging screw 3 and locking the upper nut II 61 and the lower nut II 62, the height and level of the base plate 4 can be adjusted.

[0028] To achieve lightweight adjustment of the tooling, the crossbeam 2 can be made of galvanized steel sheet. The crossbeam 2 can be constructed using a U-shaped sheet metal bending structure, which ensures the strength of the crossbeam 2 while reducing the overall weight of the tooling. To further reduce the weight of the tooling, the base plate is designed as follows: the two sides of the base plate 4 are bent towards the crossbeam 2 along its length to form flanges 41. This structure also reduces the overall weight of the tooling.

[0029] Furthermore, the middle part of the end face of the base plate 4 facing away from the crossbeam 2 (the part located between the two flanges 41) serves as the reference plane 42. The purpose of setting the reference plane 42 is to achieve contact between the thermocouple 8 and the reference plane 42, thereby achieving precise and uniform height of the thermocouple 8. In this scheme, the length of the crossbeam 2 is greater than the length of the base plate 4, and the crossbeam 2 is located above the base plate 4, which facilitates the support member 12 to cross the outer frame plates 71 on both sides of the furnace body 7, while avoiding the base plate 4 from interfering with the internal structure of the furnace body 7. In this embodiment, the length of the base plate 4 can be determined according to the width of the inner cavity 72 of the furnace body equipment.

[0030] As shown in the figure, the adjustment fixture is placed across the lower furnace body. The two ends of the crossbeam 2 are supported at the plane of the outer frame plate 71. The slot 121 of the support member 12 is inverted onto the outer frame plate 71. Since the width of the slot 121 matches the outer frame plate 71, the support is stable. First, adjust the locking member I5 to adjust the crossbeam 2 to a suitable height, while ensuring that the crossbeam 2 is horizontal. Adjust the nut of the locking member II6 to adjust the base plate 4 to a suitable height, while ensuring that the base plate 4 is horizontal. Then adjust the height of the thermocouple 8 to ensure that the top of the thermocouple 8 contacts the reference plane 42 of the base plate 4. Finally, use the fixing clip 81 to lock and fix the thermocouple 8.

[0031] The adjustment fixture in this scheme can be height-adjusted according to different furnace body specifications. The height of the crossbeam 2 and the bottom plate 4 can be adjusted to adapt to different furnace body specifications.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
