Description

Technical Field

[0001] The present invention relates to the technical field of measurement auxiliary devices, and in particular to a membrane wall tube panel auxiliary detection device for clean low-carbon cycle waste heat utilization. Background Art

[0002] The membrane-wall boiler tube panel is a single piece of tube panel welded together, offering excellent airtightness. Only a thin layer of insulation is required on the outside of the panel, preventing direct contact between the high-temperature flue gas and the furnace wall, thus preventing slagging. The panel can be manufactured in panels at the factory, facilitating on-site installation.

[0003] During the manufacturing process of membrane-wall boiler tube panels, various dimensions, such as horizontal lateral curvature, horizontal longitudinal curvature, tube end irregularity, and lateral curvature, need to be measured to determine if the panel is qualified. Currently, the measurement method used is relatively primitive. For example, when measuring tube end irregularity, contour blocks are placed on the outermost tubes on either side of the panel, and then a powder line is drawn to measure. Because the contour blocks require manual control of the tubes, measuring a single panel requires at least three people, making it extremely inefficient. Furthermore, the movement of the hands can easily cause measurement errors. Summary of the Invention

[0004] In view of the defects in the prior art, the purpose of the present invention is to provide a membrane wall tube screen auxiliary detection device for clean low-carbon cycle waste heat utilization, which makes the measurement efficiency higher and the measurement error smaller.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a membrane wall tube panel auxiliary detection device for clean low-carbon cycle waste heat utilization, comprising two measurement components, the measurement components comprising:

[0006] A reference rod and a cross rod, wherein the reference rod is fixedly connected to the cross rod, and a first plane is formed between the reference rod and the cross rod;

[0007] A reference arm, the reference arm being fixedly connected to the reference rod, and the reference arm having a notch extending inward;

[0008] a plurality of claw feet, each of the plurality of claw feet being disposed above the first plane and spaced apart along the circumferential direction, wherein a center line between the plurality of claw feet is perpendicular to the first plane, a first end of the claw foot being fixedly connected to the reference rod, a second end of the claw foot being a free end, an outwardly protruding contact portion being formed between the two ends of the claw foot, the contact portion being in close contact with the inner wall of the tube; and

[0009] A hanging rod, wherein the first end of the hanging rod is fixedly connected to the reference rod, and the second end of the hanging rod is formed with a hook.

[0010] Furthermore, the claw feet are made of stainless steel and are elastic.

[0011] Furthermore, the angle between the reference rod and the reference arm is 45°, a second plane is formed between the reference rod and the reference arm, a third plane is formed between the reference rod and the center line between the multiple claw feet, and the angle between the third plane and the second plane is 45°.

[0012] Furthermore, the number of the claws is four.

[0013] Furthermore, the reference arm, the cross bar and the hook are all located on the same side of the reference bar.

[0014] Furthermore, the claw foot is made of stainless steel welding wire ER308 and has a diameter of 2.5 mm.

[0015] Furthermore, the hanging rod is located on the inner side of the plurality of claw feet.

[0016] Beneficial effects of the present invention: The present invention provides a membrane wall tube screen auxiliary detection device for clean low-carbon cycle waste heat utilization. When in use, first hang the two ends of the powder line on the hooks of the two measuring components respectively. Then insert the two measuring components into the corresponding pipes respectively. At this time, the contact parts on the multiple claws will be in close contact with the inner wall of the corresponding pipe, so that the entire measuring component remains stable. Then move the measuring component appropriately and adjust the powder line to the appropriate position. At this time, the powder line can be used as a reference line. The entire use process only requires one person to complete the operation, so the measurement efficiency is higher. At the same time, the stability of the measuring component is better, so the measurement error is also smaller. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0024] In addition, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. In the description of the present invention, "plurality" means more than two, unless otherwise specifically defined.

[0025] like Figure 1-3 As shown, the present invention provides a membrane wall tube panel auxiliary detection device for clean, low-carbon cycle waste heat utilization, comprising two measurement assemblies 10. The two measurement assemblies 10 are identical in size and shape, and are symmetrical to each other. Specifically, the measurement assemblies 10 include a reference rod 11, a crossbar 12, a reference arm 13, a claw foot 14, and a hanging rod 15.

[0026] The reference rod 11 and the cross rod 12 are vertically arranged and fixedly connected, and a first plane is formed between the reference rod 11 and the cross rod 12 .

[0027] The reference arm 13 is disposed above the first plane and is fixedly connected to the reference rod 11 . The reference arm 13 is provided with an inwardly extending annular notch 131 .

[0028] There are multiple claw legs 14, all positioned above the first plane and spaced evenly along the circumference. The centerline between the claw legs 14 is perpendicular to the first plane. The first ends of the claw legs 14 are fixedly connected to the reference rod 11, while the second ends are free. An outwardly protruding contact portion 141 is formed between the two ends of the claw legs 14, which tightly contacts the inner wall of the tube 21. The diameter of the circle formed by the protruding portions of the claw legs 14 is slightly larger than the inner diameter of the tube 21.

[0029] The hanging rod 15 is disposed above the first plane. A first end of the hanging rod 15 is fixedly connected to the reference rod 11 , and a hook 16 is formed at a second end of the hanging rod 15 .

[0030] The specific process for measuring pipe end misalignment on a pipe panel 20 is as follows: First, the operator hangs the ends of a chalk line 30 on the hooks 16 of the two measuring assemblies 10, respectively, and loops the chalk line 30 around the reference rod 11 and crossbar 12. Next, the operator inserts the two measuring assemblies 10 into the outermost pipes 21 on either side of the pipe panel 20, respectively, until the reference rod 11 and crossbar 12 are firmly seated against the end faces of the pipes 21. At this point, the contact portions 141 on the multiple claws 14 are in close contact with the inner walls of the corresponding pipes 21, thus maintaining the stability of the entire measuring assembly 10. The chalk line 30 is then adjusted, and plumb bobs 31 are installed at each end. The weight of the plumb bobs 31 helps maintain the straightness of the chalk line 30. Since the reference rods 11 in the two measuring assemblies 10 have the same diameter and height, the chalk line 30 can now serve as a reference line to assist in measuring pipe end misalignment. The entire process can be completed by one person, saving manpower and significantly improving work efficiency. At the same time, the measuring component 10 has good stability, and thus can effectively avoid measurement errors caused by shaking caused by a person holding the equal height block with his palm for a long time.

[0031] Using the same method, the chalk line 30 can be suspended in the notch 131 of the reference arm 13. The claws 14 can be used to adjust the two measuring assemblies 10. The entire measuring assembly 10 can be moved up and down, forward and backward, left and right, and can be rotated. Finally, the chalk line 30 is adjusted to the same height as the outer surface of the tube 21. The plumb line 31 is then used to keep the chalk line 30 straight, and the horizontal lateral curvature of the tube panel 20 can be measured. The same method can also be used to place the two measuring assemblies 10 at either end of the tube 21 on the same side of the tube panel 20, allowing the horizontal longitudinal curvature and lateral curvature of the tube panel 20 to be measured. Therefore, when used in different locations, this device can be used to assist in measuring different types of tube panel 20 dimensions, meeting a wide range of measurement needs.

[0032] In one embodiment, the claw feet 14 are made of stainless steel and are elastic.

[0033] The claw feet 14 made of stainless steel can avoid rust, which can avoid material loss caused by rust and save costs; on the other hand, it can also avoid measurement errors caused by volume expansion of various components due to rust.

[0034] Because the claws 14 are elastic, once the measuring assembly 10 is inserted into the tube 21, the contact portions 141 on the claws 14 come into close contact with the inner wall of the tube 21. This increases the pressure between the claws 14 and the inner wall of the tube 21, thereby improving the stability of the measuring assembly 10. It also allows the measuring assembly 10 to be used with a variety of tubes 21 with different inner diameters, enhancing its applicability.

[0035] In one embodiment, the angle between the reference rod 11 and the reference arm 13 is 45°. A second plane is formed between the reference rod 11 and the reference arm 13, and a third plane is formed between the reference rod 11 and the centerline of the plurality of claw legs 14. The angle between the third plane and the second plane is 45°. Because the chalk line 30 is suspended from the notch 131 of the reference arm 13, this design allows operators to easily adjust the position of the chalk line 30 when measuring the horizontal transverse curvature, horizontal longitudinal curvature, and lateral curvature of the tube panel 20.

[0036] In one embodiment, there are four claw feet 14 , which are arranged at equal intervals along the circumferential direction. The contact portions 141 on the four claw feet 14 are in close contact with the inner wall of the tube 21 , thereby improving the stability of the measuring assembly 10 .

[0037] In one embodiment, the reference arm 13 , the crossbar 12 and the hook 16 are all located on the same side of the reference bar 11 to facilitate the operator in hanging the powder line 30 .

[0038] In one embodiment, the claw foot 14 is made of ER308 stainless steel welding wire and has a diameter of 2.5 mm. ER308 stainless steel welding wire has excellent strength and elasticity, a long service life, and is readily available and inexpensive. Because the structure of this device is simple, operators can also purchase and manufacture it themselves, making it suitable for large-scale deployment.

[0039] In one embodiment, the hanging rod 15 is located inside the plurality of claw feet 14 .

[0040] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as illustrative and non-restrictive in all respects. The scope of the present invention is defined by the appended claims rather than the foregoing description, and all changes that come within the meaning and range of equivalents of the claims are intended to be included therein.

[0041] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
