Description

Technical Field

[0001] This utility model relates to the field of low-pressure turbine support technology, and more specifically, to a rotor-stator support device for disassembling a low-pressure turbine. Background Technology

[0002] With the continuous development of aerospace technology, low-pressure turbines are increasingly widely used in engines. To improve the performance of low-pressure turbines, it is necessary to conduct detailed flow field analysis and experimental research. When testing low-pressure turbines, precise support and fixation of the test specimen are required. Existing support devices can fix the rotor and stator when supporting the test specimen. However, due to the different sizes and shapes of different test specimens, the clamping angle and support height vary when fixing different specimens. To prevent the support device from shaking during the experiment, it is usually fixed to the ground. However, the clamping angle and height of existing support devices are usually fixed, making it difficult to adjust their height and clamping angle after fixing them to the ground. This results in the support device failing to stably support the test specimen. Therefore, we propose a low-pressure turbine rotor and stator disassembly support device. Utility Model Content

[0003] The purpose of this invention is to provide a low-pressure turbine rotor-stator support device to solve the problem mentioned in the background art that it is difficult to adjust the height and clamping angle of the existing support device after it is fixedly installed on the ground.

[0004] To achieve the above objectives, this utility model provides a low-pressure turbine disassembly rotor-stator support device, comprising multiple support components. Each support component includes a support frame, a support rod on the upper side of the support frame, a connecting pipe on the support rod, a support tube fixedly mounted on the upper side of the connecting pipe, a connecting block fixedly mounted on the upper side of the support tube, an adjusting sleeve on the upper side of the connecting block, one end of the adjusting sleeve rotatably mounted inside the connecting block, a height adjusting component on the upper side of the adjusting sleeve, and a lug on the upper side of the height adjusting component.

[0005] As a further improvement to this technical solution, the height adjustment component includes an adjusting nut, which is fixedly disposed on the upper side of the adjusting screw sleeve. An adjusting screw is rotatably inserted through the middle of the adjusting nut, and one end of the adjusting screw is rotatably disposed inside the support tube.

[0007] The user rotates multiple handles to drive the adjusting sleeve and adjusting nut to rotate. The pin is used to prevent the adjusting screw from rotating with the adjusting sleeve. When the adjusting sleeve rotates, it drives the adjusting screw to move up and down to adjust the height of the device.

[0008] As a further improvement to this technical solution, the support frame includes a chassis, a steel pipe is fixedly installed on the upper side of the chassis, and the connecting pipe is fixedly installed on the upper side of the steel pipe.

[0009] As a further improvement to this technical solution, a handle is symmetrically fixed on one side of the steel pipe, and multiple support plates are provided on the lower side of the handle. The support plates are fixed between the chassis and the steel pipe, and multiple bolts are fixed in the middle of the chassis.

[0010] The chassis supports the steel pipe, two handles make it easy for users to grip and move the device, and multiple support plates provide stable support for the steel pipe.

[0011] As a further improvement to this technical solution, a connecting component is provided between the two support components located on different sides. The connecting component includes a connecting frame, and the two ends of the connecting frame are fixedly provided with joints for connecting with steel pipes.

[0012] As a further improvement to this technical solution, one end of the connecting frame is threaded with two fixing nuts, and the middle of the two fixing nuts is threaded with a positive and negative screw. T-slots are symmetrically fixed on the lower sides of the two chassis located on the same side.

[0013] The user first connects one end of the connecting frame to a steel pipe. When the positive and negative screws rotate, they retract from the middle of the connecting frame and adjust the length of the connecting frame. Then the user connects the other end of the connecting frame to another steel pipe. The T-slot and the chassis are connected by bolts. The T-slot is used to fix the chassis to the ground.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this low-pressure turbine disassembly rotor-stator support device, the user rotates the handle to drive the adjusting sleeve to rotate. When the adjusting sleeve rotates, it drives the adjusting nut to rotate. At the same time, the adjusting nut drives the adjusting screw to move up and down.
