Description

Technical Field

[0001] This utility model relates to the field of gas turbine power generation technology, and specifically to a disassembly device for a gas turbine combustion chamber. Background Technology

[0002] A gas turbine is a thermal engine that generates high-temperature, high-pressure gas by burning fuels (natural gas, diesel, hydrogen, etc.), which drives a turbine to rotate and output mechanical energy. Gas turbines are now being used more and more widely due to their many excellent characteristics, such as high efficiency, cleanliness, and high degree of automation.

[0003] The combustor is a key component of a gas turbine. In a gas turbine, compressed air is compressed by the compressor and then enters the combustor, where it mixes with fuel and burns to form high-temperature, high-pressure gas. This gas then enters the turbine, driving the turbine blades to rotate at high speed, converting internal energy into mechanical energy. Part of this mechanical energy is used to drive the compressor to operate continuously, while the other part is output as useful work.

[0004] Therefore, the primary function of the combustor is to ensure the effective combustion of fuel and compressed air from the compressor within the combustion chamber, and to guide the high-temperature combustion gases to the turbine, driving it to perform work. Located between the compressor and the turbine, the combustor is the "heart" of the gas turbine.

[0005] However, for gas turbines in dual-fuel units, especially dual-fuel units operating in islanded mode, the combustion chamber is easily damaged due to factors such as uneven fuel distribution or incomplete combustion when facing complex combustion conditions. It is necessary to remove it for inspection, repair or even replacement.

[0006] In the face of this situation, in order to ensure the reliable operation of the system, it is necessary to ensure the efficiency and quality of replacement. In the existing technology, when disassembling the combustion tube, the combustion tube is generally removed from the combustion chamber manually, which requires a high level of professional skills from the construction personnel and is inefficient during disassembly. Utility Model Content

[0007] In view of the technical problems of low production efficiency during disassembly and removal due to damage to the combustion tube in the existing technology, this utility model provides a disassembly device for gas turbine combustion tubes. It has a simple structure, is easy to operate, and improves the efficiency of construction personnel in disassembling the combustion tube.

[0008] The present invention adopts the following technical solution:

[0009] A disassembly device for a gas turbine combustor includes a disassembly plate. The disassembly plate is provided with a hook and a support that are rotatably connected. The hook is used to hook the combustor when disassembling it. The support is located near an inner corner of the disassembly plate and serves as a fulcrum for the rotation of the disassembly plate when disassembling the combustor.

[0010] It should be further explained that the width of the disassembly plate gradually decreases from the side of the support member towards the side away from the support member. This serves two purposes: firstly, it reduces the area of ​​the disassembly plate, thereby reducing the operating space during use and facilitating operation in confined combustion chambers; secondly, the reduced width of the disassembly plate makes it easier to grip at the hand end, saving time and effort; and finally, the reduced width of the disassembly plate lowers the overall weight of the invention, saving material and making it easier to carry.

[0011] It should be further explained that the hook component includes a vertical section, with a first horizontal section and a second horizontal section connected to its upper and lower ends respectively. The first and second horizontal sections are distributed on both sides of the vertical section, and the first, vertical, and second horizontal sections are an integral structure. The function of the first horizontal section is to hook onto the holes on the surface of the combustion cylinder, facilitating the removal of the combustion cylinder. The function of the vertical section is to provide a longer hooking length for the main structure of the hook component. The function of the second horizontal section is to form a rotatable connection with the disassembly plate, allowing the hook component to rotate on the disassembly plate.

[0012] It should be further explained that the second horizontal section is inserted into the disassembly plate and rotates around the insertion point. Its purpose is to simplify the insertion structure, making it easy to process and manufacture.

[0013] It should be further explained that after the second horizontal section is inserted into the disassembly plate, the exposed end of the second horizontal section is provided with a first pin hole, and a first pin is provided in the first pin hole. The function is to lock the hook at the upper limit of the disassembly plate through the cooperation of the first pin hole and the first pin, so as to prevent the hook from coming off the disassembly plate.

[0014] It should be further explained that a first washer is fitted onto the second horizontal section, and the first washer is located between the first pin and the disassembly plate. The function of the first washer is to protect the first pin, preventing it from being damaged by friction with the disassembly plate during rotation, and at the same time, to adjust and fill the gap between the first pin and the disassembly plate.

[0015] It should be further explained that the support component is a U-shaped block. After the disassembled plate is inserted between the two vertical plates of the support component, a shaft is inserted. Both ends of the shaft extend beyond the two vertical plates of the support component, and the extended portions of the shaft have second pin holes, each containing a matching second pin. The purpose of the U-shaped support component is that it includes a horizontal surface, providing strong stability when in contact with other planes as a fulcrum, preventing lateral swaying. Simultaneously, the U-shaped block contains two vertical plates, creating an insertion space between them for the disassembled plate, facilitating installation.

[0016] It should be further explained that a second washer is provided between the second pin and the outer side of the support member, and the second washer is sleeved on the shaft. The function of the second washer is to protect the second pin, prevent the second pin from being damaged by friction with the outer side of the support member during rotation, and at the same time, adjust and fill the gap between the second pin and the outer side of the support member.

[0017] It should be further explained that the disassembly plate is inclined from the support end to the hook end. This is to move the hook away from the outer wall of the combustion chamber and closer to the combustion cylinder, increasing the distance between the hook and the outer wall of the combustion chamber, thus facilitating the hooking operation during combustion.

[0018] The beneficial effects of this utility model are as follows: This utility model has a simple structure and is easy to operate. When in use, the support can be pressed against the outer wall of the combustion chamber as a fulcrum for disassembling the plate. At the same time, the hook is used to hang on the hole on the combustion cylinder, and the plate is rotated to disassemble. Under the lever principle, the combustion cylinder can be taken out, which saves time and effort, improves the efficiency of construction personnel in disassembling the combustion cylinder, and ensures the quality of construction work.

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0028] Example 1

[0029] Combination Figure 1 , Figure 2 This utility model provides a disassembly device for a gas turbine combustor, including a disassembly plate 1. The disassembly plate 1 is made of steel plate (thickness 5mm) by cutting and welding. The disassembly plate 1 is provided with a hook 2 and a support 7 that are rotatably connected. The hook 2 is used to hook the combustor when disassembling it. The support 7 is located near an inner corner of the disassembly plate 1 and serves as a fulcrum for the rotation of the disassembly plate 1 when disassembling it.

[0030] In order to reduce the area of ​​the disassembly plate 1 of this utility model, thereby reducing the operating space during use and facilitating operation in a narrow combustion chamber, the width of the disassembly plate 1 of this utility model gradually decreases from the side of the support member 7 to the side away from the support member 7. After the width of the disassembly plate 1 is reduced, it is easier to grip at the hand end, saving time and effort. At the same time, the reduction in the width of the disassembly plate 1 reduces the overall weight of this utility model, saves material, and makes it easy to carry.

[0031] Hook component 2 is made of steel wire with an outer diameter of 4-6mm, combined with... Figure 3The hook component 2 includes a vertical section 22, with a first horizontal section 21 and a second horizontal section 24 connected to its upper and lower ends respectively. The first horizontal section 21 and the second horizontal section 24 are distributed on both sides of the vertical section 22. The first horizontal section 21, the vertical section 22, and the second horizontal section 24 are an integral structure. After the second horizontal section 24 is inserted into the disassembly plate 1, the exposed end of the second horizontal section 24 is provided with a first pin hole 23, and a first pin 3 is provided in the first pin hole 23. Through the cooperation of the first pin hole 23 and the first pin 3, the hook component 2 is locked at the upper limit on the disassembly plate 1 to prevent the hook component 2 from coming off the disassembly plate 1. In order to provide protection for the first pin 3 and prevent the first pin 3 from being damaged by friction with the disassembly plate 1 during rotation, and to adjust and fill the gap between the first pin 3 and the disassembly plate 1, the present invention provides a first washer 4 sleeved on the second horizontal section 24. The first washer 4 is located between the pin 3 and the disassembly plate 1.

[0032] Combination Figure 4 , Figure 5 The support member 7 of this utility model is a U-shaped block. After the disassembly plate 1 is inserted between the two vertical plates of the support member 7, a shaft 5 is inserted. The two ends of the shaft 5 extend beyond the two vertical plates of the support member 7, and the extended parts of the shaft 5 are provided with second pin holes 51, and the second pin holes 51 are provided with matching second pins 6. The function of the support member 7 being a U-shaped block is that the U-shaped block contains a horizontal surface, which provides strong stability when in contact with other planes when used as a fulcrum, and will not wobble from side to side. At the same time, the U-shaped block contains two vertical plates, and the space between the two vertical plates can form an embedding space for the disassembly plate 1, which is convenient for installation. In order to provide protection for the second pin 6 and prevent the second pin 6 from being damaged by friction with the outer surface of the support member 7 during rotation, and at the same time to adjust and fill the gap between the second pin 6 and the outer surface of the support member 7, a second washer 8 is provided between the second pin 6 and the outer surface of the support member 7. The second washer 8 is sleeved on the shaft 5.

[0033] To move the hook assembly away from the outer wall of the combustion chamber and closer to the combustion cylinder, and to increase the distance between the hook assembly 2 and the outer wall of the combustion chamber for easier hooking during combustion, the disassembly plate 1 of this invention is inclined from the support member 7 end towards the hook assembly 2 end. Figure 2 The inclined side 9 is shown in the figure.

[0034] Combination Figure 6The working process of this utility model is as follows: First, adjust the utility model to the downward position of the hook 2. Then, place the plane of the support 7 against the plane of the burner outer wall 11. At this time, the hook 2 is in the suspension device. According to the position of the combustion cylinder 10 in the combustion chamber, adjust the first horizontal section 21 of the hook 2 to hook onto the hole on the combustion cylinder 10. The selection of the hole can be determined according to the actual position of the end of the hook 2. Then, hold the narrow side of the disassembly plate 1 and rotate the disassembly plate 1 upward with the support 7 as the fulcrum. Under the action of the lever principle, the combustion cylinder 10 is removed. The operation is simple. Each component of this utility model can be manufactured independently and installed on site. It is flexible in use and the processing size can be adjusted at any time according to the gas turbine model.
