[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0023] At least one embodiment of the present application provides a vibration probe positioning tool, which includes a telescopic device, a universal adjustment device and a probe clamping adjustment device connected in sequence. The probe clamping adjustment device is used to clamp vibration measuring probes 1 of different specifications. The universal adjustment device is used to adjust the clamping angle of the probe clamping adjustment device to clamp the vibration measuring probe 1. The telescopic device is used to adjust the telescopic length of the vibration probe positioning tool.
[0024] According to the technical solution provided by the embodiment of the present application, by setting a telescopic device, the vibration probe positioning tool can freely adjust the telescopic length for high-altitude measurement, and can avoid the need to set up scaffolding and other facilities, with high measurement efficiency and simple measurement process. For narrow spaces or areas with high-temperature and high-pressure gases, the vibration probes 1 of different specifications can be clamped by using the probe clamping adjustment device of the vibration probe positioning tool; by using the telescopic device, the vibration probe 1 can be delivered to the target position without being affected by the complex environment of the site (high target position, narrow space, local position inaccessible, etc.), thereby completing the vibration measurement of the complex environment; and through the universal adjustment device, the clamping angle can be flexibly adjusted according to the test environment while the clamping position remains unchanged, and the vibration measurement can be completed quickly, ensuring that personnel are away from narrow spaces or areas with potential safety hazards, and effectively ensuring industrial safety. By using the vibration probe positioning tool, it is simple to use, can break through the environmental restrictions of the industrial site, quickly and efficiently realize the vibration measurement of mechanical parts under complex conditions, and improve the efficiency and safety of vibration measurement of mechanical equipment parts under complex conditions.
[0025] The vibration probe positioning tool can be used in various complex environments, such as complex industrial sites where the vibration measurement environment of mechanical parts is complex, and some mechanical parts to be measured are located in high places or in narrow spaces and other places that are inaccessible to human hands. The vibration probe positioning tool has a wide range of applications and is a universal tool for mechanical parts vibration measurement. For example, the vibration probe positioning tool can be promoted and used in other similar industrial sites in China, not limited to the power industry, but also in other industries such as petroleum and chemical industry. It has a very wide range of applications and is highly competitive.
[0026] In at least one embodiment of the present application, reference Figure 1 The probe clamping and adjusting device comprises an adjustable clamping head 2, a guide locking screw 3 and a clamping head locking cap 13. The adjustable clamping head 2 is used to clamp the vibration measuring probe 1, and the clamping head locking cap 13 is installed on the guide locking screw 3. The clamping head locking cap 13 is used to make the adjustable clamping head 2 clamp the vibration measuring probe 1 when tightened. In this way, the adjustable clamping head 2 is detachable and replaceable, which is convenient for maintenance.
[0027] In at least one embodiment of the present application, reference Figure 2 The adjustable clamping head 2 includes a clamping head fixing block 10 and a clamping head adjusting block 12. The clamping position between the clamping head fixing block 10 and the clamping head adjusting block 12 is used to clamp the vibration measuring probe 1. The clamping head locking cap 13 is used to generate a clamping force between the clamping head fixing block 10 and the clamping head adjusting block 12 when tightened.
[0028] In at least one embodiment of the present application, the adjustable clamping head 2 is an adjustable universal clamping head of various shapes. Thus, by adopting the adjustable universal clamping head of various shapes, the stable clamping of vibration probes of various shapes (round, square, etc.) can be ensured, and the universal use of vibration measuring probes of various sizes of round and square shapes can be ensured.
[0029] In at least one embodiment of the present application, reference Figure 2 The probe clamping and adjusting device further comprises a rubber probe protection layer 11. The rubber probe protection layer 11 is arranged inside the clamping head fixing block 10 and the clamping head adjusting block 12, and is used to protect the vibration measuring probe 1. Thus, by providing the rubber probe protection layer 11, the measurement stability can be improved without damaging the measuring probe.
[0030] For example, the rubber probe protection layer 11 may be a rubber pad.
[0031] In at least one embodiment of the present application, reference Figure 1 and Figure 3 The universal adjustment device comprises a universal adjustment joint 4, a universal joint locking nut 5 and a connecting bolt 6. The connecting bolt 6 connects the probe clamping adjustment device and the telescopic device.
[0032] In at least one embodiment of the present application, reference Figure 1 The telescopic device includes a telescopic rod 7, a freely adjustable locking and positioning sleeve 8, and a plastic non-slip handle sleeve 9. The telescopic rod 7 is connected to the connecting bolt 6. The plastic non-slip handle sleeve 9 is embedded in the lower end of the lowest section of the telescopic rod 7. The freely adjustable locking and positioning sleeve 8 is installed in the middle of the adjacent sections of the telescopic rod 7. In this way, by arranging the telescopic rod 7 and the freely adjustable locking and positioning sleeve 8 in the telescopic device, the telescopicity of the telescopic device and the stability after telescopic expansion are achieved. In addition, by arranging the plastic non-slip handle sleeve 9 in the telescopic device, a human body-shaped handle type is adopted, which is convenient for people to hold and not easy to slip out of the hand.
[0033] In at least one embodiment of the present application, the telescopic rod 7 is a carbon stepless adjustable telescopic rod. In this way, since the carbon stepless adjustable telescopic rod is made of a special high-strength carbon material, on the one hand, the rod body will not bend due to the weight of the probe, and on the other hand, the telescopic rod is light in weight, combined with its telescopic function, it has good portability and mobility, and provides an effective extension length for the probe. And since the length of the telescopic rod has a stepless adjustment function, the length adjustment is flexible and free, and it is easy to use.
[0034] It should be noted that when the clamping head locking cap 13 is tightened, a clamping force is generated between the clamping head fixing block 10 and the clamping head adjusting block 12 , so that the vibration measuring probe 1 is fixed to the front end of the telescopic rod 7 .
[0035] In the above embodiment, the vibration probe positioning tool is installed by assembling with the mechanical vibration measuring head (i.e., the vibration measuring probe 1), and the vibration measuring probe 1 is stably fixed between the clamping head fixing block 10 and the clamping head adjusting block 12 by tightening the clamping head locking cap 13, and then the universal adjustment joint 4 is adjusted and the universal joint locking nut 5 is locked, and then the vibration measuring probe 1 is firmly connected to the telescopic rod by tightening the connecting bolt 6 and the telescopic rod 7, and the telescopic rod is adjusted to the required length by adjusting the freely adjustable locking positioning sleeve on the telescopic rod. In this way, all-round vibration measurement of inaccessible mechanical parts can be performed.
[0036] The following is an example of the installation method of the vibration probe positioning tool in combination with a specific implementation method. The installation method of the vibration probe positioning tool includes the following steps a to c.
[0037] a. Inlay the plastic non-slip handle cover 9 at the lower end of the lower section of the telescopic rod 7;
[0038] b. Install the freely adjustable locking and positioning sleeve 8 between the adjacent sections of the telescopic rod 7, and connect the telescopic rod 7 and the clamping head fixing block 10 as a whole through the connecting bolts 6;
[0039] c. Clamp the vibration measuring probe 1 at the clamping position between the clamping head fixing block 10 and the clamping head adjusting block 12, install the clamping head locking cap 13 on the guide locking screw 3, tighten the clamping head locking cap 133 to generate a certain clamping force between the clamping head fixing block 10 and the clamping head adjusting block 12, so that the vibration measuring probe 1 is fixed at the front end of the telescopic rod 7.
[0040] At least one embodiment of the present application further provides a vibration measurement method of a vibration measuring probe, which is implemented by using the vibration probe positioning tool in the above embodiment of the present application. The vibration measurement method of the vibration measuring probe includes the following steps.
[0041] S1: Confirm that the vibration probe positioning tool has been installed, the vibration probe 1 has been clamped stably, and the probe clamping adjustment device is not loose.
[0042] For example, when confirming that the probe clamping and adjusting device is not loose, it can be confirmed that the adjustable clamping head 2 in the probe clamping and adjusting device is not loose and the guide locking screw 3 is locked.
[0043] S2: Adjust the length of the telescopic device according to the required length.
[0044] For example, the freely adjustable locking and positioning sleeve 6 in the telescopic device can be adjusted to pull out telescopic rods 7 of different thicknesses from the lower telescopic rod and lock them in place.
[0045] S3: According to the measured spatial position, the universal adjustment device is used to adjust the clamping angle of the vibration measuring probe 1 by the probe clamping adjustment device.
[0046] For example, the universal adjustment joint 4 in the universal adjustment device can be adjusted, and the universal joint locking nut 5 can be locked.
[0047] S4: Use the locked and secure vibration probe positioning tool to deliver the vibration probe 1 to the position to be measured for measurement.
[0048] In at least one embodiment of the present application, the vibration measurement method further includes step S5.
[0049] S5: If the vibration measuring probe needs to be replaced, the distance between the clamping head fixing block 10 and the clamping head adjusting block 12 is adjusted by rotating the clamping head locking cap 13, and vibration measuring probes of different sizes and shapes are inserted. Then, the clamping head locking cap 13 is tightened to generate a clamping force of a certain strength between the clamping head fixing block 10 and the clamping head adjusting block 12 to complete the fixation of the vibration measuring probe 1.
[0050] In some embodiments, the above steps S1 to S4 may be repeated to perform measurement.
[0051] It should be noted that the combination of the various technical features in the embodiments of the present application is not limited to the combination described in the embodiments of the present application or the combination described in the specific embodiments, and all technical features described in the present application can be freely combined or combined in any way unless there is a contradiction between them.
