[0015] Figure 2 This is a schematic diagram of the tail end of the flame tube in an embodiment of this utility model. Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0017] like Figure 1 As shown in the figure, this utility model embodiment proposes a professional tool for disassembling and assembling the flame tube of a gas turbine, including a crossbeam 1, a sleeve 2, a rotating shaft screw 3, a handle 4, a sleeve 5, a positioning block 6, and a hook 7;

[0018] The crossbeam 1 has a transverse through hole in the middle; the sleeve 2 is connected to the middle of the crossbeam 1, and the inner hole of the sleeve 2 is aligned with the through hole on the crossbeam 1.

[0019] The lead screw 3 extends into the sleeve 2 from one end; one end of the sleeve 5 passes through the central hole of the crossbeam 1 and extends into the sleeve 2 from the other end; the lead screw 3 extends into the sleeve 5, and the lead screw 3 and the sleeve 5 cooperate to form a lead screw transmission pair; at least one guide groove 501 is provided on the side of the sleeve 5, and the crossbeam 1 is provided with an inner protrusion that is engaged with the guide groove 501;

[0020] The end of the lead screw 3 is connected to a handle 4; the other end of the sleeve 5 is connected to a positioning block 6; and a hook 7 is also connected to the positioning block 6.

[0021] The tail end of the gas turbine's flame tube is like Figure 2As shown, multiple nozzle peripheral holes 13 are also provided around the central hole 12 of the secondary fuel nozzle in the flame tube. When disassembling the flame tube, the two ends of the crossbeam 1 are fixed to the outer wall of the combustion chamber to provide a force point for the entire tool. Rotating the handle 4 in the forward direction causes the screw 3 to rotate in the forward direction, driving the sleeve 5 to extend forward, so that the positioning block 6 enters the central hole 12 of the secondary fuel nozzle, preventing slippage and damage to the flame tube during disassembly. Then, the hook 7 is hooked onto the outer wall 1201 of the central hole 12 of the secondary fuel nozzle. Rotating the handle 4 in the reverse direction causes the screw 3 to rotate in the reverse direction, driving the sleeve 5 to retract, and the flame tube can be smoothly separated from the combustion chamber guide bushing under the pulling force of the hook 7. The tool proposed in this embodiment of the utility model greatly improves the efficiency of gas turbine flame tube maintenance and disassembly, while avoiding minor damage to the flame tube during maintenance, and improving the safety of flame tube maintenance equipment.

[0022] More preferably, bolts 8 are provided at both ends of the crossbeam 1; the bolts 8 can be used to fix both ends of the crossbeam 1 to the outer wall of the combustion chamber. Bolt holes can be provided on the end face of the outer wall of the combustion chamber.

[0023] More preferably, the two ends of the crossbeam 1 are respectively provided with locking blocks 9; the bolt 8 passes through the end of the crossbeam 1 and the locking blocks 9; the locking blocks 9 are used to lock onto the outer wall of the combustion chamber; which can improve the connection stability of the crossbeam 1.

[0024] Specifically, the positioning block 6 includes a positioning block body 601 and a positioning column 602; the positioning column 602 is integrally constructed with the positioning block body 601, and the diameter of the positioning column 602 is smaller than the diameter of the positioning block body 601; the diameter of the positioning column 602 is adapted to the inner diameter of the secondary fuel nozzle center hole 12; so that the positioning block 6 can be securely inserted into the secondary fuel nozzle center hole 12.

[0025] More preferably, the front end of the positioning post 602 is provided with a chamfer 603; the chamfer 603 can make it easier for the positioning post 602 to enter the center hole 12 of the secondary fuel nozzle.

[0026] More preferably, two guide grooves 501 are provided, symmetrically arranged on the sleeve 5 (perpendicular to) Figure 1 (The direction of the paper surface is left and right); this allows the sleeve 5 to slide forward and backward more smoothly, and also prevents the sleeve 5 from rotating.

[0027] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
