Description

Technical Field

[0001] This utility model belongs to the field of thermal instrumentation tube technology, and in particular relates to a thermal instrumentation tube installation structure. Background Technology

[0002] Thermal instrumentation tubing is used to connect thermal instruments to sampling components or other related equipment, transmitting the measured medium or signal. Common materials include carbon steel, stainless steel, copper, and copper alloys. Different materials are suitable for different working environments and media. Connection methods between instrumentation tubing and instruments, sampling components, and other equipment include welding, threaded connections, and compression fittings. Welded connections offer advantages such as good sealing and high strength, but require specialized welding techniques; threaded connections are easy to install, but attention must be paid to sealing; compression fittings are suitable for applications requiring frequent disassembly and also offer good sealing performance.

[0003] When welding thermal instrument tubes, workers need to hold the tubes and align them with the instruments and sampling components. To meet welding requirements, the gap between the tubes and the components needs to be controlled. This process is cumbersome and prone to misalignment. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a thermal instrument tube installation structure to more accurately resolve the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a thermal instrument tube mounting structure, including two annular plates, each of which is provided with a clamping assembly. Annular mounting seats are fixedly connected to opposite sides of the two annular plates. The shape of the annular mounting seats is the same as that of the annular plates. A connecting plate is provided between the two annular mounting seats.

[0007] In one example, the clamping assembly includes two sliding rods that are slidably connected to an annular plate and pass through the annular plate. Two pressing blocks are provided at opposite ends of the two sliding rods.

[0008] In one example, a horizontal plate is fixedly connected to one end of each of the two sliding rods, and an extrusion block is fixedly connected to the horizontal plate, with the extrusion block located on both sides of the horizontal plate.

[0009] In one example, a mounting bracket is fixedly connected to one side of the annular plate, a crossbar is fixedly connected to one side of the sliding rod, a support plate is fixedly connected to one end of the crossbar, a fixed seat is fixedly connected to one side of the mounting bracket, a bidirectional threaded rod is rotatably connected to the fixed seat, the bidirectional threaded rod passes through the two support plates and is threadedly connected to the support plates, and a limiting block is fixedly connected to both ends of the bidirectional threaded rod.

[0010] In one example, each of the two extrusion blocks has a triangular groove on one side opposite to the other, and the sidewalls of the triangular grooves on the extrusion blocks are provided with rubber pads.

[0011] In one example, both annular plates and the annular mounting base are provided with notches, and the angle between the sidewall of the notch and the center of the annular plate is 45 degrees.

[0012] In one example, the outer sides of the two annular mounting bases are provided with through grooves, and sliding rings are slidably connected in the grooves. The sliding rings have a cross-sectional shape similar to that of the annular mounting bases, and the connecting plate is fixedly connected to the two sliding rings.

[0013] The thermal instrument tube installation structure proposed in this utility model can bring the following beneficial effects:

[0014] Firstly, by setting up a connecting plate and two annular plates, when the clamping assembly clamps the thermal instrument tube to be installed and the source component, the thermal instrument tube and the source component are adjusted to be opposite each other, with their centers on the same straight line. At the same time, the gap between the thermal instrument tube and the source component is adjusted. At this time, the connecting plate keeps the thermal instrument tube to be welded and the source component in a relative state. At this time, the worker can directly perform welding without having to hold the thermal instrument tube, which is more convenient. It also avoids the worker holding the thermal instrument tube while welding, which would cause the thermal instrument tube and the source component to be misaligned.

[0015] Secondly, by setting a bidirectional threaded rod, rotating the bidirectional threaded rod controls the movement of the two crossbars, so that the extrusion blocks move synchronously at the same time, clamping the thermal instrument tube located in the annular block, making the operation more convenient. The four extrusion blocks on both sides move the same distance, which makes it easier to push the thermal instrument tube to make the center of the thermal instrument tube aligned with the center of the annular plate.

[0023] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown in the figure, an embodiment of this utility model proposes a thermal instrument tube installation structure, including two annular plates 1, each equipped with a clamping assembly 2. One annular plate 1 is opposite to the thermal instrument tube to be welded, and the other is opposite to a source component, such as a temperature sampling sleeve. Both are clamped and fixed by the clamping assembly 2. Annular mounting seats 3 are fixedly connected to the opposite sides of the two annular plates 1. The shape of the annular mounting seats 3 is the same as that of the annular plates 1. A connecting plate 4 is provided between the two annular mounting seats 3, and the two annular plates 1 are connected as one unit by the connecting plate 4. When the clamping assembly 2 clamps the thermal instrument tube to be installed and the source component, the thermal instrument tube and the source component are adjusted to be opposite each other, with their centers on the same straight line. At the same time, the gap between the thermal instrument tube and the source component is adjusted. At this time, the connecting plate 4 keeps the thermal instrument tube to be welded and the source component in a relative state. At this time, the worker can directly perform welding without having to hold the thermal instrument tube, which is more convenient and avoids the worker holding the thermal instrument tube while welding, which would cause the thermal instrument tube and the source component to be misaligned.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the clamping assembly 2 includes two sliding rods 21, which are slidably connected to the annular plate 1. The sliding rods 21 pass through the annular plate 1. Two extrusion blocks 22 are provided at opposite ends of the two sliding rods 21. During extrusion, the extrusion blocks 22 press against the outside of the thermal instrument tube to clamp and fix it. The method of fixing the source component is the same as that of the thermal instrument tube. The opposite ends of the two sliding rods 21 are fixedly connected to the horizontal plate 5. The extrusion blocks 22 are fixedly connected to the horizontal plate 5 and are located on both sides of the horizontal plate 5. Four extrusion blocks 22 are provided on the inner side of each annular block. The four extrusion blocks 22 clamp the thermal instrument tube from both sides. The four extrusion blocks 22 clamp from two positions to keep the thermal instrument tube straight and to align the thermal instrument tube with the center of the annular plate 1.

[0026] like Figure 2 and Figure 3 As shown, a mounting bracket 6 is fixedly connected to one side of the annular plate 1, and a crossbar 7 is fixedly connected to one side of the sliding rod 21. A support plate 8 is fixedly connected to one end of each crossbar 7. A fixing seat 9 is fixedly connected to one side of the mounting bracket 6. A bidirectional threaded rod 10 is rotatably connected to the fixing seat 9. The bidirectional threaded rod 10 passes through the two support plates 8 and is threadedly connected to the support plates 8. Limiting blocks 11 are fixedly connected to both ends of the bidirectional threaded rod 10. When clamping the thermal instrument tube or the source component, it is only necessary to rotate the bidirectional threaded rod 10 to control the movement of the two crossbars 7, so that the extrusion blocks 22 move synchronously at the same time to clamp the thermal instrument tube located in the annular block. The operation is more convenient. The four extrusion blocks 22 on both sides move the same distance, which makes it easy to push the thermal instrument tube to make the center of the thermal instrument tube align with the center of the annular plate 1.

[0027] like Figure 2 As shown, each of the two extrusion blocks 22 has a triangular groove 12 on one side opposite to the other. The sidewalls of the triangular groove 12 on the extrusion block 22 are provided with rubber pads. When the extrusion block 22 extrudes the thermal instrument tube, the thermal instrument tube is stuck in the triangular groove 12, which makes the fixation of the thermal instrument tube and the source component more stable and avoids the situation of side slippage.

[0028] like Figure 2 and Figure 3 As shown, both annular plates 1 and annular mounting base 3 are provided with notches 13. The angle between the side wall of the notch 13 and the center of the annular plate 1 is 45 degrees. The notches 13 on the annular plates 1 and annular mounting base 3 facilitate the entry of the thermal instrument tube and the source component into the two annular plates 1 for clamping and fixing.

[0029] like Figure 4As shown, the outer sides of the two annular mounting bases 3 are provided with through grooves, and sliding rings 14 are slidably connected in the grooves. The cross-sectional shape of the sliding rings 14 is similar to that of the annular mounting bases 3. The connecting plate 4 is fixedly connected to the two sliding rings 14. During welding, it is necessary to perform annular welding around the outside of the thermal instrument tube. The connecting plate 4 may obstruct the welding. Therefore, when the connecting plate 4 blocks the welding position during welding, the connecting plate 4 can be pushed, and the sliding rings 14 will slide off the annular mounting base to change the position of the connecting plate 4 and avoid it. Since the angle of the notch 13 is 45 degrees, the sliding rings 14 will not detach from the annular mounting bases 3 during the sliding process.

[0030] Working principle: The thermal instrument tube and the source component are brought into the annular plate 1 and the annular mounting base 3 through the notch 13 on the annular plate 1 and the annular mounting base 3. The bidirectional threaded rod 10 is rotated to control the movement of the two crossbars 7, so that the extrusion blocks 22 move synchronously and clamp the thermal instrument tube located in the annular block. The four extrusion blocks 22 on both sides move the same distance, pushing the thermal instrument tube to align the center of the thermal instrument tube with the center of the annular plate 1. During welding, the connecting plate 4 can be pushed, and the sliding ring 14 slides out from the annular mounting base to change the position of the connecting plate 4 and avoid obstacles.

Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model.
