[0052] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0053] Example:

[0054] like Figure 1 As shown, an embodiment of the present application discloses a pipeline detection hanger for a power generation system, which is used to suspend the pipeline to facilitate subsequent observation or detection to see whether the position of the pipeline is deformed.

[0055] Its specific structure includes:

[0056] Base 1, which is made of steel and can be fixed on a workbench or the ground;

[0057] A housing 2, wherein a receiving cavity 201 is provided inside the housing 2, and the housing 2 is mounted on the base 1, and a longitudinal slide groove 202 is provided on the housing 2, and the receiving cavity 201 inside the housing 2 can be used to install other components, such as springs, and the longitudinal slide groove 202 is convenient for detection;

[0058] The connecting frame 3 is vertically installed inside the accommodating cavity 201, and the bottom end of the connecting frame 3 extends to the outside of the connecting frame 3. The connecting frame 3 is used to form a support, so as to cooperate with subsequent main telescopic parts and other components to complete the detection;

[0059] The main telescopic member 4 is installed in the middle of the accommodating cavity 201. One end of the main telescopic member 4 is connected to the top inner wall of the accommodating cavity 201, and the other end is matched with the connecting frame 3. The main telescopic member 4 is a component that mainly bears the tension. A suspension rod is installed at the bottom of the main telescopic member 4 for suspending the pipeline. During subsequent maintenance or inspection, it can be known whether the position of the pipeline is offset.

[0060] Two auxiliary telescopic parts 5 are installed inside the accommodating cavity 201, and the side of the auxiliary telescopic parts 5 cooperates with the top of the main telescopic part 4. The auxiliary telescopic parts 5 are also parts that bear tension and assist the main telescopic parts 4 to ensure that the corresponding parts can work stably.

[0061] The indicator pin 6 is installed on the top of the main telescopic member 4, and the end of the indicator pin 6 is located inside the longitudinal slide groove 202; in the present application, the pipeline and other components can be first installed on the bottom end of the main telescopic member 4 through a hanger, and the position of the indicator pin 6 is fixed at this time; after a long period of work, the position of the indicator pin 6 can be observed to determine whether the pipeline is deformed.

[0062] In one embodiment, a locking structure 7 is installed on the outer side of the shell 2. The locking structure 7 cooperates with the indicator pin 6. The locking structure 7 can better achieve locking, ensure the stability of the overall structure, and facilitate the detection of the water pressure test.

[0063] Specifically, the locking structure 7 includes:

[0064] Two locking racks 701 are arranged side by side and spaced apart, and the locking racks 701 are located on both sides of the longitudinal slide groove 202. The locking racks 701 in the present application are convenient for subsequent locking and also convenient for subsequent detection;

[0065] The locking block 702 is installed on the indicator pin 6, and the locking block is located between the two locking racks 701. The outer side of the locking block 702 is a tooth surface and meshes with the inner wall of the locking rack 701. The present application completes the locking by toothed meshing to facilitate water pressure detection.

[0066] The locking structure 7 in the present application is installed only during the water pressure test, because the pipeline needs to bear a certain load, and the present application also bears a large load at this time. In order to ensure stability, a locking structure is provided to prevent the main telescopic member and the auxiliary telescopic member from being damaged. In subsequent work, the locking block 702 of the locking structure 7 is removed.

[0067] Specifically, Figure 2 As shown, the connecting frame 3 includes:

[0068] Two mounting seats 301 are installed inside the accommodating cavity 201 at intervals;

[0069] A plurality of adjusting screws 302, the top of which is connected to the mounting seat 301;

[0070] The connecting plate 303 is installed at the bottom of the adjusting screw 302, and a through hole 304 is opened on the connecting plate 303; the present application is provided with multiple components, and the installation of the subsequent sleeve position is facilitated by the mounting seat 301 and the connecting plate 303.

[0071] Among them, a sleeve 305 is installed on the connecting plate 303, and the sleeve 305 cooperates with the bottom of the main telescopic part 4; the sleeve 305 is used to cooperate with the main telescopic part 4, that is, to prevent the main telescopic part 4 from being deformed and then offset, which affects the user's misjudgment of whether the pipeline is offset.

[0072] Specifically, the main telescopic member 4 includes:

[0073] A conduit 401 is vertically arranged, and the bottom end of the conduit 401 corresponds to the through hole 304;

[0074] The main spring 402 is sleeved on the guide tube 401, and the bottom of the main spring 402 is located inside the sleeve 305, that is, the sleeve 305 can ensure the stability of the main spring 402 to prevent it from deflecting when compressed, which affects the detection;

[0075] A pressing plate 403 is installed on the top of the conduit 401, and the pressing plate 403 cooperates with the subsequent conduit 401 to perform lifting and lowering movements;

[0076] Two roller side plates 404 are installed above the pressure plate 403, and the roller side plates 404 cooperate with the indicator pin 6;

[0077] Two rollers 405 are installed at intervals on the pressure plate 403; the present application realizes force transmission by arranging the rollers 405 and the pressure plate 403 to cooperate with each other. When the catheter 401 is subjected to tension, it will drive the pressure plate 403 to move downward, thereby squeezing the main spring 402 to complete the suspension.

[0078] Specifically, the auxiliary telescopic member 5 includes:

[0079] A secondary spring 501, one end of which is connected to the inner wall of the accommodating cavity 201;

[0080] A secondary spring pressure plate 502 is installed at the other end of the secondary spring 501;

[0081] A secondary spring pressure rod 503 is installed on a side of the secondary spring pressure plate 502 away from the secondary spring 501;

[0082] The adjusting rod 504, the bottom of which is hinged to the accommodating cavity 201, and the top of which cooperates with the roller 405, and the side of the adjusting rod 504 away from the main spring 402 contacts the end of the secondary spring pressure rod 503; the secondary spring 501 and the main spring 402 in the present application cooperate with each other, and when the pressure plate 403 is pulled downward, it can drive the roller 405 to move downward, thereby pushing the adjusting rod 504 to squeeze the corresponding secondary spring 501, thereby completing a stable suspension.

[0083] The side of the adjusting rod 504 facing the roller 405 is arc-shaped, and the arc-shaped portion makes it easier for the roller 405 to push the adjusting rod 504 more smoothly.

[0084] A groove 204 is formed on the top of the housing 2 , and a top plate 203 is disposed inside the groove 204 . The top plate 203 can ensure strength and stability of the overall structure during installation.

[0085] The end surface of the indicator pin 6 is provided with a warning color to facilitate observation by the user.

[0086] To further explain the present application, the present application is used for suspending pipes. During normal operation, the locking block 702 of the locking structure is taken out, and then the main telescopic member 4 and the auxiliary telescopic member 5 work normally. During maintenance, the machine is stopped to see whether the indicator pin 6 returns to its original position. If not, it is determined that the pipe has been deformed.

[0087] When conducting a load test, the locking block 702 is installed in place and then tested. During the test, it is necessary to determine whether the pipeline is leaking. Generally, when the pipeline is overloaded, the tension formed by the pipeline is large. Therefore, damage to the main telescopic part and the auxiliary telescopic part is avoided. The locking block 702 is used to lock the pipeline to prevent damage to other parts.

[0088] In the specification of the present utility model, a lot of specific details are described. However, it is understood that the embodiments of the present utility model can be practiced without these specific details.
