[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: a portable gas turbine turning gear device, including a servo wrench turning gear 100, on which a drive gear 101 is provided; a mounting shell 200 is installed on the servo wrench turning gear 100, and a cleaning structure is installed inside the mounting shell 200. The cleaning structure is used to clean impurities and metal debris in the gap of the drive gear 101. An elastic component is connected to the cleaning structure to ensure the contact effect between the cleaning structure and the drive gear 101. A T-shaped strip 300 is connected to the cleaning structure, and a disassembly and assembly component is connected to the T-shaped strip 300 to disassemble or install the cleaning structure.

[0027] Furthermore, the cleaning structure includes a linkage slide plate 201, which is slidably installed inside the mounting housing 200. A slide rod 202 is slidably installed inside the linkage slide plate 201. A mounting plate 203 is installed at one end of the slide rod 202. A connecting plate 204 is detachably installed on one side of the mounting plate 203. Brush bristles 205 are installed on one side of the connecting plate 204. A motor 206 is installed on one side of the mounting housing 200. The output end of the motor 206 passes through the mounting housing 200 and is fitted with a turntable 207. The turntable 207... A linkage shaft 208 is installed on one side, and a strip groove 209 is opened inside the linkage slide plate 201. The linkage shaft 208 is movably installed in the strip groove 209. When the motor 206 is turned on, the turntable 207 can be rotated. The turntable 207 will drive the linkage slide plate 201 to move horizontally back and forth through the cooperation of the linkage shaft 208 and the strip groove 209. When the linkage slide plate 201 moves, it can drive the mounting plate 203 and the connecting plate 204 to move back and forth through the slide rod 202, thereby driving the bristles 205 to reciprocate and clean the drive gear 101.

[0028] Furthermore, the elastic component includes an auxiliary spring 210, which is slidably sleeved on the slide rod 202. The two ends of the auxiliary spring 210 are respectively installed between the linkage slide plate 201 and the mounting plate 203. A stop block 211 is installed at one end of the slide rod 202. Under the elastic force of the auxiliary spring 210, the mounting plate 203 can be pushed to move towards the drive gear 101, thereby improving the contact effect between the bristles 205 and the drive gear 101. The stop block 211 can prevent the slide rod 202 from coming loose from the linkage slide plate 201.

[0029] Furthermore, the linkage slide plate 201 has two guide holes 212 inside, and a fixed guide rod 213 is slidably installed in each of the two guide holes 212. The two fixed guide rods 213 are installed on the inner wall of the mounting shell 200. When the linkage slide plate 201 moves, it can slide on the fixed guide rods 213 through the guide holes 212. The setting of the guide holes 212 and the fixed guide rods 213 can restrict the movement of the linkage slide plate 201 in the horizontal direction and prevent it from deviating from its movement direction.

[0030] Example 2: As Figure 1-5 To facilitate the disassembly, replacement, or cleaning of the bristles 205, a disassembly and assembly assembly is provided. This assembly includes a T-shaped slot 301, which is located inside the mounting plate 203. A T-shaped strip 300 is detachably installed within the T-shaped slot 301 and mounted on one side of the connecting plate 204. Two fixing seats 302 are mounted on one side of the mounting housing 200, and a fixing rod 303 is installed between the two fixing seats 302. A baffle 304 is slidably mounted on the fixing rod 303, and the baffle 304 is aligned with one side of the T-shaped strip 300. A limiting spring 305 is slidably sleeved on the contact and fixing rod 303. One end of the limiting spring 305 is installed on the corresponding fixing seat 302, and the other end of the limiting spring 305 is installed on one side of the baffle 304. Pushing the baffle 304 can make it disengage from the obstruction of the connecting plate 204 and the mounting plate 203. At this time, the T-shaped strip 300 can be exposed. Pulling the connecting plate 204 upward can drive the T-shaped strip 300 to be pulled out from the T-shaped slot 301 so that the bristles 205 can be disassembled for replacement or cleaning. The remaining features are the same as in Embodiment 1.

[0031] The working principle is as follows: After the servo wrench control unit 100 is installed, it can control the drive gear 101 to rotate. The drive gear 101 drives the gear of the gas turbine to rotate. At the same time as the drive gear 101 rotates, the motor 206 is turned on. The output end of the motor 206 drives the turntable 207 to rotate. The turntable 207 drives the linkage shaft 208 to rotate. The rotating linkage shaft 208 moves in a circular motion within the slot 209 and drives the linkage slide plate 201 to move horizontally back and forth through the slot 209. The movable sliding plate 201 can drive the mounting plate 203 and the connecting plate 204 to move back and forth via the sliding rod 202, thereby driving the brush bristles 205 to reciprocate and clean the drive gear 101, removing impurities or metal debris from the gaps between the teeth of the drive gear 101. Under the elastic force of the auxiliary spring 210, the mounting plate 203 can be pushed towards the drive gear 101, improving the contact effect between the brush bristles 205 and the drive gear 101. During the process, the sliding rod 202 can slide inside the sliding plate 201.

[0032] By pushing the baffle 304, it can slide on the fixed rod 303 and compress the limiting spring 305. At the same time, the moving baffle 304 will disengage from the obstruction of one side of the connecting plate 204 and the mounting plate 203, exposing the connection point. Pulling the connecting plate 204 upwards can drive the T-shaped strip 300 out of the T-shaped slot 301, so that the bristles 205 can be removed for replacement or cleaning. During installation, the T-shaped strip 300 on the connecting plate 204 is reinserted into the T-shaped slot 301, and then the baffle 304 is released. At this time, the compressed limiting spring 305 will push the baffle 304 to move and reset, so that the baffle 304 will once again protect one side of the T-shaped strip 300, preventing the connecting plate 204 from loosening.

[0033] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
