As Figure 2 shown, the ventilation pipe bracket assembly 30 is composed of three parts: a fixed seat 31, a bracket 32, and a compression nut 33. The bracket 32 is designed with an opening and has a certain elasticity itself, and is fixed on the conical surface of the fixed seat 31 through the compression nut 33.

[0004] As the torque of the compression nut increases, the bracket 32 undergoes elastic deformation due to the extrusion of the conical surface 34, the diameter increases, and it adsorbs on the inner hole wall of the turbine shaft 20. There are clear regulations for the installation position of the bracket 32 in the shaft hole. Taking the right bracket assembly as an example.

[0005] As Figure 1 shown, the axial distance L between the right fixed seat 31 and the right end face of the turbine shaft 20. The outer diameter of the fixed seat 31 is larger than the minimum diameter of the left inner hole of the low-pressure turbine shaft. During actual assembly, the air duct bracket assemblies need to be assembled one by one from left to right, and the installation process of the bracket is relatively cumbersome.

[0006] In view of this, the inventor of the present application has designed a tool for adjusting the installation position of an inner hole bracket and a using method thereof in order to overcome the above technical problems. Summary of the Invention

[0051] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings.

[0052] Now the embodiments of the present invention will be described in detail with reference to the drawings. Now the preferred embodiments of the present invention will be described in detail, and the examples are shown in the drawings. In any possible case, the same reference numerals will be used throughout the drawings to represent the same or similar parts.

[0053] In addition, although the terms used in the present invention are selected from well-known and commonly used terms, some of the terms mentioned in the specification of the present invention may be selected by the applicant according to his or her judgment, and the detailed meanings are described in the relevant parts of the description herein.

[0054] In addition, it is required to understand the present invention not only through the actual terms used, but also through the meaning implied by each term.

[0055] As Figures 3 to 6 shown, the present invention discloses an inner hole bracket installation position adjustment tool, which includes a positioning plate 100 and a T-shaped push-pull assembly 200. Among them, one end of the T-shaped push-pull assembly 200 passes through the positioning plate 100 and is fixed by a fixing part 300. The other end of the T-shaped pull rod assembly 200 can rotate an angle and is used to move along the axis of the turbine shaft.

[0056] Here, the positioning plate 100 is used to achieve the positioning and installation of the T-shaped push-pull assembly 200, and to enable the T-shaped push rod or pull rod to move along the axis of the turbine shaft. The fixing member 300 can be, for example, a nut, which is used to generate a pulling force to pull the T-shaped push-pull assembly 200 to move rightward.

[0057] Preferably, the T-shaped push-pull assembly 200 includes a rod body 210, a joint structure, and a rotating head 220. Among them, one end of the rod body 210 passes through the positioning plate 100, the other end of the rod body 210 is rotatably connected to the rotating head 220 through the joint structure, and the connection between one end of the rod body 210 and the positioning plate 100 is fixed by a fixing member 300.

[0058] The rod body 210 here can preferably be set as a push rod or a pull rod. A thread is provided at the end of the rod body 210. After the nut (i.e., the fixing member 300) is installed, the reaction force generated at the joint surface with the positioning plate 100 drives the entire bracket assembly to move rightward.

[0059] The joint structure includes a mounting portion 230 and a joint shaft 240. The mounting portion 230 is arranged on the rotating head 220, one end of the rod body 210 is installed in the mounting portion 230, and is connected through the joint shaft 240.

[0060] Here, the rotating head 220 is connected to the rod body by a joint structure and can rotate at the joint to change the effective diameter of the head. That is, the rotating head 220 rotates at the joint so that the diameter of the head of the rotating head 220 is smaller than the inner diameter of the bracket fixing seat. After the T-shaped push-pull assembly 200 passes through the inner hole of the bracket fixing seat, it can hook the left end face of the fixing seat in reverse.

[0061] More preferably, as shown in combination Figure 3 Another joint can be added axially between the rotating head 220 and the rod body 210 to convert the T-shaped pull rod into a T-shaped push rod. Under the double-joint connection, the rotating head 220 is fixed and cannot rotate.

[0062] In this embodiment, the rotating head 220 can preferably be set as a plate-like structure or a block-like structure.

[0063] Furthermore, the inner hole bracket installation position adjustment tool can also include at least two limiting rods 400, which are used to prevent the bracket assembly from being pulled excessively. One end of the limiting rod 400 passes through the positioning plate 100, and the other end is connected to the rotating head 220, which is used to limit the T-shaped pull rod assembly 200. For example, the limiting rod 400 can be fixed on the positioning plate 100 by a thread to limit the T-shaped push-pull assembly 200 and prevent the bracket assembly from moving excessively during the rightward pulling process.

[0064] Specifically, at both ends of the bottom end surface of the positioning plate 100, there are rabbet positioning portions 110 for matching and fitting with the inner hole bracket 500. At both ends of the positioning plate 100, there are a number of through holes 120 for fixing with the turbine shaft 20.

[0065] Combined with Figures 3 to 6 , the present invention also provides a method for using the inner hole bracket installation position adjustment tool, which uses the inner hole bracket installation position adjustment tool as described above. The method includes the following steps: taking the rear end surface of the turbine shaft (such as Figure 1 the right end surface shown) as the positioning reference, making the head of the T-shaped push-pull assembly parallel to the rear end surface of the turbine shaft, and the T-shaped push-pull assembly moves along the axis of the turbine shaft to adjust the inclined bracket assembly.

[0066] Preferably, the method further includes: when the assembly position of the bracket assembly is on the right, and the axial distance L (refer to Figure 1 shown) between the bracket assembly and the outer end of the turbine shaft is less than the design value, after the T-shaped push-pull assembly extends into the inner hole of the turbine shaft (for example, extends into the inner hole of the turbine shaft from the right), through the thrust of the T-shaped push-pull assembly (such as Figure 3 shown, the thrust F received by the push rod is transmitted through the right end surface of the fixed seat), overcoming the frictional force between the bracket and the inner hole wall, to straighten and push the bracket in place.

[0067] Further, the method further includes: when the assembly position of the bracket is on the left, and the axial distance L (refer to Figure 1 shown) between the bracket assembly and the outer end of the turbine shaft is greater than the design value, after the T-shaped push-pull assembly passes through the inner hole of the bracket fixing seat, it reversely hooks the end surface of the fixing seat (such as Figure 1 the left end surface of the fixing seat shown), through the pulling force of the T-shaped push-pull assembly (such as Figure 3 shown, transmitting the pulling force generated by the T-shaped pull rod), overcoming the frictional force between the bracket and the inner hole wall, to straighten and pull the bracket in place.

[0068] According to the above structure and method description, for the inner hole bracket installation position adjustment tool and its using method of the present invention, the acting force is transmitted to the fixing seat through the push rod or the pull rod (i.e., the T-shaped push-pull assembly), and the acting force is greater than the frictional force between the bracket and the inner hole wall of the turbine shaft, so as to push the whole bracket assembly to move and achieve the purpose of position adjustment.

[0069] The inner hole bracket installation position adjustment tool can avoid repeated disassembly and assembly of the bracket. Taking the installation of the rightmost bracket as an example, the installation position of the bracket may have the following three types of situations:

[0070] First, the assembly position is on the left, and the axial distance L is greater than the design value;

[0071] Second, the assembly position is on the right, and the axial distance L is less than the design value;

[0072] III. The bracket is installed obliquely.

[0073] If the assembly deviations described in the second and third above occur, after the T-shaped push-pull assembly extends into the inner hole of the turbine shaft from the right side, the thrust F received by the push rod is transmitted through the right end face of the fixed seat, overcoming the friction between the bracket and the inner hole wall to straighten and push the bracket to the left in place.

[0074] If the assembly deviations described in the first and third above occur, through the articulated T-shaped push-pull assembly, the rotating head can rotate at the joint, so that the diameter of the head of the T-shaped push-pull assembly is smaller than the inner diameter of the bracket fixed seat. The adjusting tool can pass through the inner hole of the bracket fixed seat and then hook the left end face of the fixed seat in reverse, transmitting the pulling force generated by the rod body, overcoming the friction between the bracket and the inner hole wall to straighten and pull the bracket to the right in place. A limiting rod is provided on the adjusting tool to prevent the bracket assembly from being over-pulled.

[0075] In summary, the inner hole bracket installation position adjustment tool and its usage method of the present invention have the following advantages:

[0076] 1. When the installation position of the bracket is deviated, the installation position of the bracket can be adjusted on the premise of avoiding repeated disassembly and assembly of the bracket.

[0077] 2. The tool is simple, easy to operate, and has low production cost.
