[0002] During the use of railway vehicles, parts will gradually wear, corrode and be damaged. In order to keep the vehicles in good quality condition, ensure driving safety and extend the service life of the vehicles, various inspections and repairs must be carried out on the railway vehicles. In the existing technology, due to the heavy weight of the railway wheel pairs, they need to be lifted and hoisted by a maintenance crane for maintenance, which takes a long time and has a high maintenance cost. Since the wheel pairs are suspended in the air during maintenance, they are prone to shaking and hitting maintenance personnel, thereby causing safety accidents. At the same time, during the maintenance process, the wheel pairs slide over the maintenance double rails, and the wheel pairs are manually pushed to slide on the maintenance double rails. However, the maintenance double rails are not straight tracks, and there are turning points therein. The weight of the railway wheel pairs is heavy, so it is extremely inconvenient to turn manually. Therefore, the utility model provides a maintenance and steering structure for railway vehicle wheels to solve the problems raised in the above background technology. Utility Model Content

[0003] The purpose of the utility model is to provide a maintenance steering structure for railway vehicle wheels, which can adjust and clamp the wheel pair to improve maintenance safety, automatically lift the wheel pair to reduce maintenance costs, and at the same time rotate the direction of the wheel pair for easy use.

Specific implementation manner

[0019] In order to further understand the content, features and effects of the present utility model, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings.

[0020] Please refer to Figures 1 to 3 below, the overhaul steering structure of a railway vehicle wheel according to an embodiment of the present utility model will be described in detail with reference to the accompanying drawings.

[0021] Refer to Figures 1 to 3 As shown in the figure, the overhaul steering structure of the railway vehicle wheel is characterized by comprising: a support platform 1, a steering component 4, an adjusting component 3, and a lifting component 2. The lifting component 2 is fixed to the top end of the support platform 1, the adjusting component 3 is fixed to the side of the lifting component 2, and the steering component 4 is fixed inside the support platform 1.

[0022] Refer to Figure 1 As shown in the figure, the lifting component 2 includes an I-shaped chute block 201 fixed to the top end of the support platform 1. The inside of the I-shaped chute block 201 is slidably connected with an I-shaped slider 202. The top end of the I-shaped slider 202 is fixedly connected with a one-way hydraulic cylinder 203. A rotating plate 6 is fixed to the side of the I-shaped chute block 201.

[0023] First, manually start the one-way hydraulic cylinder 203 to make the one-way hydraulic cylinder 203 start to extend downward. Since the bottom end of the one-way hydraulic cylinder 203 is fixed with an I-shaped slider 202, when the one-way hydraulic cylinder 203 extends downward, it will drive the I-shaped slider 202 to slide downward inside the I-shaped chute block 201, so that the I-shaped slider 202 drives the adjusting component 3 to move downward to the bottom. Then, the staff pushes the wheel pair to be overhauled into the adjusting component 3. After adjusting the adjusting component 3, manually close the one-way hydraulic cylinder 203 to make the one-way hydraulic cylinder 203 stop extending downward and start to retract. Furthermore, the one-way hydraulic cylinder 203 drives the I-shaped slider 202 to slide upward inside the I-shaped chute block 201, so that the I-shaped slider 202 drives the adjusting component 3 and the wheel pair to lift upward.

[0024] Refer to Figure 1 And Figure 2The adjustment component 3 includes a fixing frame 301 fixed to the side of the I-type slide block 201, and a wheel pair splint 302 is fixed to the bottom end of the fixing frame 301, and a first fixing plate 303 is fixed to one end of the wheel pair splint 302, and a movable adjustment plate 304 is fixed to the other end. A sliding rod 305 passes through the movable adjustment plate 304 and the first fixing plate 303, and a first driving motor 306 is fixed to the side of the movable adjustment plate 304, and a second fixing plate 7 is at the bottom end of the first driving motor 306. The bottom end of the second fixing plate 7 is rotatably connected to the rotating plate 6 through a rotating rod 8, and a rotating plate 6 is fixed to the side of the I-type slide block 201.

[0025] After the wheel pair for inspection is pushed into the adjusting assembly 3, the first driving motor 306 is manually started, so that the first driving motor 306 starts to push the movable adjusting plate 304 to slide on the surface of the slide rod 305 toward the first fixed plate 303. Since the first fixed plate 303 is fixed to one end of the wheel pair clamping plate 302 and the movable adjusting plate 304 is fixed to the other end, when the movable adjusting plate 304 moves on the slide rod 305, its movable adjusting plate 304 will drive the wheel pair clamping plate 302 to clamp the wheel pair. When the above-mentioned I-type slide block 201 drives the adjusting assembly 3 and the wheel pair to lift upward, the second fixed plate 7 at the bottom end of the first driving motor 306 will drive the rotating plate 6 to rotate through the rotating rod 8, so that the second fixed plate 7 can support and fix the first driving motor 306 when the I-type slider 202 slides up and down inside the I-type slide block 201.

[0026] refer to Figure 3 The steering assembly 4 includes a driving gear 401 fixed inside the support platform 1, the top sleeve of the driving gear 401 is connected to the second driving motor 402, the side of the driving gear 401 is meshed with the driven gear 403, and the driven gear 403 is fixed to the bottom end of the rotating disk 5.

[0027] When it is necessary to steer the wheel pair, the second drive motor 402 is manually started, and the second drive motor 402 begins to drive the drive gear 401 to rotate. Since the side surface of the drive gear 401 is engaged with the driven gear 403, the drive gear 401 will transmit the driven gear 403 through gear engagement, causing the driven gear 403 to start rotating. At the same time, the driven gear 403 is fixed to the bottom end of the rotating disk 5, and the rotating disk 5 is fixed to the bottom end of the I-type slide block 201. Therefore, when the driven gear 403 rotates, it will drive the rotating disk 5 to rotate, so that the adjusting component 3 and the lifting component 2 will be driven by the rotating disk 5 at the same time, and then the wheel pair clamped in the adjusting component 3 will be rotated at an angle to realize the steering function.

[0028] The one-way hydraulic cylinder in the above embodiment can be directly purchased and used in reality, while the one-way hydraulic cylinder in this example adopts the MOB40 model.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
