[0046] The core of the present invention is to provide a mounting fixture for a detector to complete the test of the mechanical properties of the R angle of a steam turbine.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] like Figures 1-21 As shown, the present invention discloses a mounting fixture for a detector, which includes a mounting assembly for connecting to the detector. The mounting assembly can be installed on mutually perpendicular surfaces of a steam turbine, while ensuring that the detector and the turbine's R angle are offset. In this application, a mounting assembly is provided to provide a mounting base for the detector. The mounting assembly can be installed on mutually perpendicular surfaces of the steam turbine to facilitate R angle detection. After the mounting assembly is installed, the detector and the turbine's R angle are offset to detect the mechanical properties of the R angle. By adding the mounting assembly, on-site testing of the turbine's R angle can be achieved.

[0049] In a specific embodiment, the mounting assembly comprises a mounting base 1 and a slider 2. The mounting base 1 serves as the foundation for the entire mounting fixture, and its shape and size can be customized to suit specific needs. The slider 2 is slidably mounted on the mounting base 1, and the detector is mounted on the slider 2. Sliding the slider 2 allows the detector's position to be adjusted to measure data at multiple points, eliminating the need to repeatedly disassemble the fixture to obtain data at multiple points. This reduces workload and improves efficiency.

[0050] Furthermore, the mounting base 1 has a dovetail groove, and the slider 2 has a latching slot. The dovetail groove and the latching slot cooperate to enable the slider 2 to slide on the mounting base 1. This dovetail groove arrangement provides a stable connection and prevents the slider from tilting. Specifically, a pair of side edges of the mounting base 1 have bosses, forming dovetail grooves between the bosses and the mounting base 1. The slider 2 also has latching slots on its side edges. This way, the sides of the slider 2 cooperate with the mounting base 1, further preventing the slider 2 from tilting.

[0051] In a further embodiment, the mounting assembly further includes a knob 3 and a fastening screw 4. The knob 3 is against the slider 2, and the slider 2 can be pushed to slide by rotating the knob 3. The knob 2 is mounted on the mounting base 1 through a mounting part, and the knob 3 is mounted on the mounting part through a bearing. During the rotation of the knob 3, it can move along the extension direction of the dovetail groove. Specifically, the knob 3 can be a screw with one end against the slider 2. In practice, the slider 2 can also be driven to move by other means, such as a ball screw structure. In order to ensure the stability of the detector and prevent the detector from shaking, the mounting assembly in the present application is provided with a fastening screw 4 for locking the mounting base 1 and the slider 2. The position between the slider 2 and the mounting base 1 after the fastening screw 4 is locked and positioned to prevent the two from further displacement.

[0052] In a further embodiment, one of the pair of side edges of the mounting base 1 is provided with a chain hook 7 connected to a chain 8, and the other is provided with a first connecting member 5. The mounting base 1 in the present application needs to be fixed on the steam turbine so that the detector has an installation base. When it is necessary to test the mechanical properties of the R angle, the mounting assembly is in the first mounting position. At this time, the chain 8 is tied to the straight pipe of the steam turbine, and the first connecting member 5 is adsorbed on the disc of the steam turbine through the magnet 6. Specifically, the straight pipe is arranged perpendicular to the disc. The use of the chain 8 bundling and the magnet 6 adsorption method can simplify the installation and improve the efficiency of the installation. The magnet 6 can be adsorbed on the turbine discs of different specifications, and the chain 8 can be tied to the turbine pipes of different specifications. The clamping method is stable and has a wide range of applications. In addition, other connection methods can also be used in practice. As for the installation position of the mounting base 1, according to different detection needs, it can also be fixed on other components of the steam turbine, and all are within the protection range.

[0053] In a preferred embodiment, the aforementioned mounting base 1 comprises a rectangular main body and an integral mounting body formed at a 45° angle thereto. The chain hook 7 is mounted on the mounting body, and the aforementioned first connecting rod is mounted on the mounting base 1 on a side opposite the mounting body. To enable mounting on two perpendicular surfaces, the end of the first connecting member 5 connected to the magnet 6 is angled at 135° relative to the end connected to the mounting base 1. While only one specific shape and position of the first connecting rod 5 and chain hook 7 is provided herein, any practical method capable of mounting the mounting assembly on two perpendicular surfaces is within the scope of this protection.

[0054] In the above structure, Figure 12 The threaded hole is the hole for connecting the mounting base 1 to the first connecting member 5 when testing the R angle of the steam turbine. Figure 10 In the figure, two threaded holes can be seen in the middle of the mounting base 1. The threaded holes are symmetrical and are the holes for connecting the mounting base 1 and the second connecting member 10. Figure 10 The four equidistant threaded holes on the middle right are holes for connecting the mounting base 1 and the chain hook 7.

[0055] On the basis of the above technical solution, the axis of the bundling structure formed by the chain 8 is perpendicular to the plane used for adsorption by the magnet 6, that is, the mounting base 1 has two mutually perpendicular mounting surfaces. It can also be understood that the mounting base 1 can be installed on two mutually perpendicular mounting surfaces to facilitate the detector to detect the mechanical properties at the R angle. Specifically, the mounting assembly is set on the angle bisector of the axis and the plane, that is, on the angle bisector of the two mutually perpendicular mounting surfaces. In addition, the slider 2 slides along the intersection surface perpendicular to the axis and the plane, specifically, slides along the extension direction of the top angle of the R angle to ensure that the detector can detect the mechanical properties of different positions of the R angle. The sliding of the slider 2 is used to test the data of multiple points of the R angle, and finally a set of mechanical property data is obtained, without the need to repeatedly disassemble and assemble the fixture to obtain data from multiple test points.

[0056] In practice, the mounting base 1 has two chain hooks 7 and two chains 8, with each chain hook 7 corresponding to each other. The two chains 8 are connected by a chain fastener 9, which can adjust the length between the two chains 8 so that the chains 8 can be wrapped around straight pipes of different sizes. Specifically, the chain fastener 9 has two hooks. The above structure is symmetrical, and the connection method is described using one side as an example: the chain hook 7 is fixed to the mounting base 1 by screws, one end of the chain 8 is clamped on the chain hook 7, and the other end of the chain 8 is connected to a hook of the chain fastener 9. The two hooks of the chain fastener 9 are connected by an adjustment screw. By tightening and releasing the adjustment screw, the length between the two chains 8 can be changed.

[0057] In the field test of the R angle of the steam turbine, the field test of the straight pipe of the steam turbine also falls within the scope of detection. For the convenience of on-site testing, when designing the on-site test fixture of the R angle of the steam turbine, the on-site test of the mechanical properties of the straight pipe of the steam turbine is also considered. Since the position of the detector is different when detecting the mechanical properties of the R angle and the mechanical properties of the straight pipe, it is necessary to change the installation position of the mounting assembly. On this basis, the other pair of side edges of the mounting base 1 in the mounting fixture disclosed in the present application are provided with a second connecting member 10, and when the mounting assembly is in the second position, the second connecting member 10 is adsorbed on the disc of the steam turbine through the adsorption member 11, and the detector detects the mechanical properties of the straight pipe of the steam turbine at this time.

[0058] The mounting assembly is designed to be dual-purpose. When in its first position, one end of the mounting base 1 is connected via a chain hook 7, chain 8, and chain fastener 9, and the other end is connected via a first connector 5 and magnet 6, enabling on-site testing of the mechanical properties of the turbine's rounded corners. When in its second position, the mounting base 1 is connected via a second connector 10 and an adsorption element 11, enabling on-site testing of the mechanical properties of the turbine's straight pipes. This eliminates the need to carry multiple fixtures (except for the connectors) to perform on-site testing of turbine rounded corners and straight pipes, making carrying and transportation more convenient.

[0059] In the above embodiment, since there are two second connecting members 10 and each second connecting member 10 is fixed by an adsorption member 11, there are two adsorption members 11. Specifically, the adsorption members 11 are magnets, and the adsorption surfaces of the two adsorption members 11 are coplanar.

[0060] The second connecting member 10 is installed on the other pair of sides of the rectangular body of the mounting base 1. The two sides are parallel. The end of the second connecting member 10 connected to the adsorption member 11 has a 90° angle with respect to the end connected to the mounting base 10.

[0061] The first connecting member 5 and the second connecting member 10 disclosed in this application are both bent rods. Those skilled in the art will appreciate that they can be bent according to the installation position, length, and relationship with other components, and all are within the protection range.

[0062] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0063] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
