Description

Technical Field

[0001] This utility model relates to the technical field of hydrogen tube processing, and in particular to a fixing device for hydrogen tube processing. Background Technology

[0002] As the core carrier for large-scale, long-distance hydrogen transportation, hydrogen pipelines need to address issues such as hydrogen permeation and hydrogen embrittlement. Special materials such as plastic-coated pipes are used to improve corrosion resistance and airtightness. In response to the high permeability of hydrogen, polymer coatings are needed to reduce the risk of hydrogen leakage.

[0003] In existing technologies, when connecting hydrogen energy pipelines, it is usually necessary to trim the pipe ends to improve the stability of the hydrogen energy pipeline after connection. In most existing technologies, the hydrogen energy pipeline is fixed by fixing components and then the hydrogen energy pipeline is trimmed. However, the high temperature generated by cutting may weaken the adhesion between the coating and the metal substrate and accelerate hydrogen permeation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fixing device for hydrogen energy tube processing, so as to solve the technical problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A fixing device for hydrogen energy tube processing includes:

[0007] The base plate has a vertical plate fixedly installed on one side of the top. A rotating hole is opened in the center of the vertical plate. A rotating sleeve is installed inside the rotating hole. Two mounting slots are opened inside the rotating sleeve. An expansion bag is installed inside the mounting slot.

[0008] A sealing plate is provided at one end of the rotating sleeve, and a pressure supply component is provided on the other side of the rotating sleeve;

[0009] Several fixing posts are installed inside the rotating sleeve, between the two expansion bags;

[0010] A locking assembly is provided at the upper end of the base plate, on the side away from the upright plate.

[0011] Furthermore, the mounting groove is provided with a limit link inside, and the distance between two adjacent limit links is equal.

[0012] Furthermore, the expansion bag includes two side plates, which are disposed inside the mounting groove and fixedly connected to the two side walls of the mounting groove. The two side plates are provided with limiting holes corresponding to the limiting connecting rods, and elastic covers are provided on the outer periphery of the two side plates.

[0013] Furthermore, the outer peripheral wall of the fixed pile is provided with a sliding tube, which is fixedly connected to the rotating sleeve and communicates with the inner cavity of the rotating sleeve. The fixed pile is slidably disposed inside the sliding tube.

[0014] Furthermore, the pressure supply assembly includes a sealing plug, which is fixedly connected to the end of the rotating sleeve, and a connecting pipe is provided inside the sealing plug.

[0015] Furthermore, the locking assembly includes an arc-shaped support platform, which is fixedly connected to the base plate, and a pressing rod is rotatably provided on one side of the top of the arc-shaped support platform, with a locking bolt provided at one end of the pressing rod.

[0016] In summary, this utility model has at least one of the following beneficial technical effects:

[0017] 1. The fixing device for processing hydrogen tubes, since the expansion bag will come into contact with the inner wall of the hydrogen tube over a large area after expansion, the oil inside the expansion bag can absorb the heat of the inner wall of the hydrogen tube, so as to keep the hydrogen tube at a low temperature after cutting and processing, thereby avoiding damage to the coating on the inner wall of the hydrogen tube.

[0018] 2. The fixing device for processing hydrogen energy tubes uses a sliding tube to slide the fixing pile inside the tube wall of a rotating sleeve. As the oil inside the rotating sleeve gradually increases, it pushes the fixing pile out along the straight direction of the sliding tube. At this time, the end of the fixing pile can contact the inner wall of the hydrogen energy tube, thereby fixing the hydrogen energy tube. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings. Example 1

[0026] Reference Figures 1-4 The present invention discloses a fixing device for processing hydrogen energy tube 100, comprising:

[0027] The base plate 1 has a vertical plate 2 fixedly installed on the top of one side. A rotating hole 3 is opened in the center of the vertical plate 2. A rotating sleeve 4 is installed inside the rotating hole 3. Two mounting grooves 5 are opened inside the rotating sleeve 4. An expansion bag 6 is installed inside the mounting groove 5.

[0028] One end of the rotating sleeve 4 is provided with a sealing plate 7, and the other side of the rotating sleeve 4 is provided with a pressure supply component 8;

[0029] Several fixing posts 9 are provided inside the rotating sleeve 4 and between the two expansion bags 6;

[0030] A locking assembly 10 is provided at the upper end of the base plate 1 and on the side away from the upright plate 2.

[0031] In this embodiment, when fixing the hydrogen tube 100, the hydrogen tube 100 is inserted into the inside of the locking assembly 10, and one end of the hydrogen tube 100 is sleeved on the outer end of the rotating sleeve 4, and both expansion bags 6 are inserted into the inside of the hydrogen tube 100.

[0032] Then, the pressure supply component 8 is connected to the output end of the water pump or oil pump to fill the interior of the rotating sleeve 4 with cooling oil. As the amount of oil inside increases, the oil will support the expansion bag 6. At this time, the outer peripheral wall of the expansion bag 6 will come into contact with the inner wall of the hydrogen tube 100. At the same time, the fixing pile 9 will be pushed by the oil and will gradually come into contact with the inner wall of the hydrogen tube 100, thereby achieving the purpose of fixing the hydrogen tube 100.

[0033] After fixing, the opening of the hydrogen tube 100 is trimmed by machining the hydrogen tube 100. At this time, since the expansion bag 6 will come into contact with the inner wall of the hydrogen tube 100 over a large area after expansion, the oil inside the expansion bag 6 can absorb the heat of the inner wall of the hydrogen tube 100, so as to keep the hydrogen tube 100 at a low temperature after machining, thereby avoiding damage to the coating on the inner wall of the hydrogen tube 100.

[0034] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the mounting groove 5 is provided with a limiting link 11 inside, and the distance between two adjacent limiting links 11 is equal.

[0035] In this embodiment, the limiting link 11 is set to make the mounting groove 5 a through groove. After the expansion bag 6 is installed, the inlet end of the inner side of the expansion bag 6 corresponds to the mounting groove 5, so that the oil can fully enter the interior of the expansion bag 6.

[0036] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the expansion bag 6 includes two side plates 61, which are disposed inside the mounting groove 5 and fixedly connected to the two side walls of the mounting groove 5. The two side plates 61 are provided with limiting holes 62 corresponding to the limiting connecting rod 11, and the outer periphery of the two side plates 61 is provided with an elastic cover 63.

[0037] In this embodiment, the two sidewalls and the elastic cover 63 together form an annular ring with an oil inlet groove on the inner side, such as Figure 3 As shown, after the oil enters, the increase in the volume of the oil can push the elastic cover 63 upward, causing the elastic cover 63 to expand. During the expansion of the elastic cover 63, the outer wall of the elastic cover 63 will gradually come into contact with the inner wall of the hydrogen tube 100. At this time, when the hydrogen tube 100 is cut and generates heat, the heat can be transferred into the interior of the oil through the elastic cover 63, thereby achieving the purpose of cooling the hydrogen tube 100.

[0038] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the outer peripheral wall of the fixed pile 9 is provided with a sliding tube 12, which is fixedly connected to the rotating sleeve 4 and communicates with the inner cavity of the rotating sleeve 4. The fixed pile 9 is slidably disposed inside the sliding tube 12.

[0039] In this embodiment, the fixing pile 9 is slidably installed inside the pipe wall of the rotating sleeve 4 by the sliding pipe 12. As the oil inside the rotating sleeve 4 gradually increases, it will push the fixing pile 9 to be discharged along the straight direction of the sliding pipe 12. At this time, the end of the fixing pile 9 can contact the inner wall of the hydrogen energy pipe 100, thereby fixing the hydrogen energy pipe 100.

[0040] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the pressure supply assembly 8 includes a sealing plug 81, which is fixedly connected to the end of the rotating sleeve 4, and a connecting pipe 82 is provided inside the sealing plug 81.

[0041] In this embodiment, the sealing plug 81 is used in conjunction with the sealing plate 7 to form a sealed cavity inside the rotating sleeve 4 for storing oil. The connecting pipe 82 is used to connect to the oil pump so that external oil can be pumped into the interior of the rotating sleeve 4 to compress the elastic cover 63 and make it contact the inner wall of the hydrogen energy tube 100.

[0042] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the locking assembly 10 includes an arc-shaped support 101, which is fixedly connected to the base plate 1. A pressing rod 102 is rotatably provided on one side of the top of the arc-shaped support 101, and a locking bolt 103 is provided at one end of the pressing rod 102.

[0043] In this embodiment, the arc-shaped support 101 and the clamping connecting rod 102 are used to further lock the hydrogen tube 100, improve the stability of the hydrogen tube 100, and the clamping connecting rod 102 is locked by the locking bolt 103.

[0044] The implementation principle of the above embodiment is as follows: the pressure supply component 8 is connected to the output end of the water pump or oil pump, and the cooling oil is filled into the interior of the rotating sleeve 4. As the amount of oil inside increases, the oil will support the expansion bag 6. At this time, the outer peripheral wall of the expansion bag 6 will come into contact with the inner wall of the hydrogen energy tube 100. At the same time, the fixing pile 9 is pushed by the oil and will gradually come into contact with the inner wall of the hydrogen energy tube 100, thereby achieving the purpose of fixing the hydrogen energy tube 100.

[0045] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
