Description

Technical Field

[0001] The present invention belongs to the technical field of testing devices, and in particular relates to a testing device for a micro gas turbine generator set and a method for using the same. Background Art

[0002] Micro gas turbine generator sets have gradually become a hot spot for research and application due to their advantages such as small size, fast start-up, flexible operation and low emissions. In order to ensure the stable and safe use of micro gas turbine generator sets, testing operations are required before the micro gas turbine generator sets leave the factory.

[0003] The Chinese utility model patent application number is CN202121685549.0, which discloses a portable motor speed detection tooling that is easy to quickly support and fix. It includes a mounting plate, an adjustment mechanism is fixedly installed on the surface of the mounting plate, and a fixing mechanism is fixedly installed inside the adjustment mechanism. Two support legs are fixedly installed on one side of the surface of the mounting plate, and a detection platform is fixedly installed on the top of the two support legs. Through the provided fixing mechanism, the motor is placed on the fixed fixing ring, and the adjusting and rotating handle drives the screw rod to rotate accordingly. The rotation of the screw rod drives the threaded dynamic fixing ring to move up and down inside the slide groove to tighten the motor. An adjustment mechanism is provided to adjust the slider so that it slides on the sliding track, driving the second support column to approach or move away from one end of the first support column, and quick adjustment can be performed according to motors of different sizes.

[0004] The above-mentioned existing detection tooling of this type is suitable for detecting the rotational speed of the motor. By sliding the second support column of the adjustment mechanism, the distance between the second support column and the first support column is adjusted, and thus it is suitable for supporting and placing equipment to be detected of different lengths and sizes. Then, the dynamic fixing ring and the fixed fixing ring are used to clamp and fix the equipment to be detected, so as to achieve stable placement of the equipment to be detected. However, the overall degree of automation is low, and when clamping the equipment to be detected with a complex shape, the clamping operation is inconvenient, the scope of use is small, and it cannot perform fixed detection on gas turbine generators of various specifications, which reduces the use effect.

[0005] Moreover, when conducting test operations, traditional test devices for micro gas turbine generator sets require manual continuous adjustment of the test devices, and even require specially processed suitable positioning parts to achieve fixed operations before testing the micro gas turbine generator sets, resulting in a cumbersome and inefficient test process. Moreover, due to different test items, the data collection location for the micro gas turbine generator will also be different. In traditional technologies, testers are required to move the test equipment, which not only increases the labor intensity of the test but also easily causes damage to the test equipment, which is not conducive to the normal progress of the test operation.

[0045] One end of the first threaded rod 13 is transmission-connected to a first motor 14, which is fixedly mounted on the corresponding side plate 12. The first motor 14 is started to drive the first threaded rod 13 to rotate, and the rotation of the first threaded rod 13 drives the two connecting blocks 15 and the two movable plates 3 to move toward or away from each other.

[0046] With this design, when it is necessary to adjust the distance between the two movable plates 3, the first motor 14 is started to drive the first threaded rod 13 to rotate. The rotation of the first threaded rod 13 drives the two connecting blocks 15 to move through the threaded cooperation. At this time, the two connecting blocks 15 drive the two movable plates 3 to move on the mounting plate 2, thereby realizing the adjustment operation of the distance between the two movable plates 3.

[0047] In addition to this embodiment 1, the first motor 14 can also be fixedly mounted on the mounting plate 2, and the power output end of the first motor 14 is connected to the first threaded rod 13 through a transmission box.

The transmission rod 38 is transmission-connected to the second threaded rod 16. The rotation of the transmission rod 38 is used to drive the second threaded rod 16 to rotate.

[0051] In this embodiment 1, a worm 17 is integrally connected to the transmission rod 38 at a position inside the fixed housing 5 , and a worm wheel 19 is fixedly connected to the bottom end of the second threaded rod 16 , and the worm wheel 19 is meshed with the corresponding worm 17 .

[0052] The transmission rod 38 rotates to drive the worm 17 to rotate, and the worm 17 is meshed and connected with the worm wheel 19, thereby driving the second threaded rod 16 to rotate.

[0053] In this embodiment 1, a second motor 18 is fixedly mounted on any one of the fixed shells 5 or the movable plate 3 , and a power output end of the second motor 18 is transmission-connected to a corresponding transmission rod 38 , and the second motor 18 is started to drive the transmission rod 38 to rotate.

[0054] The two transmission rods 38 are slidably connected at one end thereof that is close to each other; when the two movable plates 3 move relative to each other, the two transmission rods 38 are driven to extend and retract.

[0055] In this embodiment 1, a connecting groove 36 is formed on the end of any one of the transmission rods 38 away from the fixed shell 5, and a connecting rod 37 is slidably and transmission-connected in the connecting groove 36, and the end of the connecting rod 37 away from the connecting groove 36 is coaxial and fixedly connected to the other transmission rod 38.

[0056] In this embodiment 1, the cross-sections of the connecting rod 37 and the connecting groove 36 are both set to be regular hexagons, and the connecting rod 37 is movably inserted into the connecting groove 36 to achieve sliding and transmission connection between the connecting groove 36 and the connecting rod 37.

[0057] With this design, when the height position of the vertical plate 6 needs to be adjusted, the second motor 18 is started, and the second motor 18 drives the corresponding transmission rod 38 to rotate, and drives another transmission rod 38 to rotate through the cooperation of the connecting rod 37 and the connecting groove 36. At this time, the two transmission rods 38 rotate through the engagement transmission of the worm 17 and the worm wheel 19 to drive the second threaded rod 16 to rotate. The second threaded rod 16 is threadedly connected to the threaded hole. The rotation of the second threaded rod 16 drives the vertical plate 6 to move up and down in the fixed shell 5, thereby adjusting the height position of the vertical plate 6 and improving the use effect.

[0058] In addition to this embodiment 1, the worm 17 and the worm wheel 19 can also be replaced by a helical gear set or a bevel gear set.

The telescopic end of the top-connected automatic telescopic rod 21 is slidably connected to the inner surface of the through hole.

[0061] With this design, when in use, the micro gas turbine generator to be tested can be placed between the support plates 20 through external lifting equipment, so that the support plates 20 are used to support and place the micro gas turbine generator, and the automatic telescopic rod 21 at the designated position is started according to actual needs. The automatic telescopic rod 21 drives the positioning plate 22 to move, so that the positioning plate 22 is connected to the outer wall of the micro gas turbine generator, thereby realizing multi-point support operation of the micro gas turbine generator, effectively improving the stability during support and reducing the impact on the equipment.

[0062] In this embodiment 1, the top-connected automatic telescopic rod 21 adopts one of an electric telescopic rod, a hydraulic cylinder, and a telescopic cylinder.
