Description

Technical Field

[0001] This utility model relates to the field of train wheel inspection technology, and in particular to a fixed platform for train wheel inspection. Background Technology

[0002] Train wheel inspection is a series of tasks that check, measure and evaluate the various performance and indicators of train wheels. Its purpose is to ensure the safety, reliability and good operating condition of train wheels, including appearance inspection, dimensional measurement and hardness testing.

[0003] Existing train wheelset inspection requires supporting the train wheelsets. Supporting the wheelsets can make the inspection process more efficient. By supporting the wheelsets, the time and effort required for manual adjustment can be reduced, and the efficiency of inspection can be improved. At the same time, supporting the wheelsets can also make the inspection process more stable and reduce errors caused by improper operation or environmental factors.

[0004] The existing patent (publication number: CN221224252U) discloses a testing platform for testing train wheelsets. By adjusting the limiting block, the train wheelset body can be limited so that the axles on both sides of the train wheelset body stop at the top of the moving block in the movable component. Then, the user connects and controls the motor through existing electrical equipment. The operation of the motor drives the control rod connected to the bottom. The control rod moves the moving block through the connecting block set on the outer wall. When the moving block contacts the train wheelset body, the mating part set on the top of the moving block can stabilize the train wheelset body. Finally, the train wheelset body is lifted, and the user can perform the test.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the slide rails proposed in these patents have a certain height. Due to the weight of the train wheels, it is inconvenient to move the train wheels to the top of the slide rail. Furthermore, during the upward movement of the train wheels before they come into contact with the mating parts, the round shape of the train wheels makes them prone to rolling when moving upwards without any constraints. Once they roll, it becomes difficult to ensure that the mating parts can accurately and precisely lift the train wheels stably.

[0006] To address this, a fixed platform for train wheel inspection is proposed. Utility Model Content

The slide rail has a certain height, and because the train wheels are heavy, it is inconvenient to move the train wheels to the top of the slide rail. Furthermore, when the train wheels move upward and do not contact the mating parts, because the train wheels are round, they are prone to rolling when moving upward without restraint.

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A fixed platform for inspecting train wheels includes a support frame 1 and a wheel body 3. Support plates 4 are fixedly connected to both sides of the bottom of the support frame 1. Support blocks 8 are provided on both sides of the bottom of the support frame 1. The surface of the wheel body 3 is in contact with the surface of the support block 8. A pulling mechanism 7 is provided between the opposite sides of the two support blocks 8. A constraint mechanism 9 is provided on the top of the support block 8.

[0029] The pulling mechanism 7 includes two first electric telescopic rods 701, two threaded rods 702, a locking ring 703, an arc plate 704, and a pull plate 705. The rear side of the threaded rod 702 is fixedly connected to the front side of the telescopic end of the first electric telescopic rod 701. The threaded rod 702 is movably inserted into the inside of the pull plate 705. The locking ring 703 is threadedly connected to the surface of the threaded rod 702. The rear side of the locking ring 703 is in close contact with the front side of the pull plate 705. The bottom of the arc plate 704 is fixedly connected to the top of the pull plate 705. The surface of the arc plate 704 is in contact with the surface of the wheel body 3.

[0030] In this embodiment: by moving the wheel body 3 to the front of the triangular block 6, connecting the pull plate 705 to the telescopic end of the first electric telescopic rod 701, and simultaneously controlling the retraction of the telescopic ends of the two first electric telescopic rods 701, the arc plate 704 pulls the wheel body 3 along the inclined surface of the triangular block 6 to the top of the support block 8. Then, rotating the rotating rod 903 causes the first arc block 901 and the second arc block 902 to constrain the wheel from the front and rear, preventing its rolling displacement. If it is necessary to raise the wheel height, the two second electric telescopic rods 2 are simultaneously controlled to retract, causing the support block 8 and the wheel body 3 to rise stably to a suitable height, facilitating... The tester, of the same height, conducted the test. First, the wheel body 3 was constrained and fixed by the first arc block 901 and the second arc block 902, and then it was lifted stably. This solved the problem in the existing patent that the slide rail has a certain height, and because the train wheel is heavy, it is inconvenient to move the train wheel to the top of the slide rail. Furthermore, when the train wheel moves upward and does not contact the mating parts, because the train wheel is round, it is easy to roll when it moves upward without constraint. Once it rolls, it is difficult to ensure that the mating parts can accurately and stably lift the train wheel.

[0031] Specifically, such as Figure 1 and Figure 5 As shown, the constraint mechanism 9 includes a first arc-shaped block 901, a second arc-shaped block 902, a rotating rod 903, and a fixed frame 904. The rotating rod 903 is threadedly connected to the inside of the fixed frame 904. The bottoms of the first arc-shaped block 901 and the second arc-shaped block 902 are both fixedly connected to the top of the support block 8. The surfaces of the first arc-shaped block 901 and the second arc-shaped block 902 are both in contact with the surface of the wheel body 3. The side of the rotating rod 903 closest to the second arc-shaped block 902 is rotatably connected to the second arc-shaped block 902.

[0032] Specifically, such as Figure 5As shown, the front and rear sides of the fixing frame 904 are fixedly connected to the limiting blocks 13, and the inside of the limiting blocks 13 is slidably connected to the limiting rods 12. The side of the limiting rods 12 near the second arc-shaped block 902 is fixedly connected to the second arc-shaped block 902.

[0033] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, a connecting plate 11 is fixedly connected between the rear sides of the two first electric telescopic rods 701, and the front side of the connecting plate 11 is fixedly connected to the rear side of the support block 8.

[0034] In this embodiment: by moving the wheel body 3 to the top of the support block 8, first contacting the surface of the first arc block 901, and then rotating the rotating rod 903, the rotating rod 903 pushes the second arc block 902 to contact the surface of the wheel body 3. At this time, the wheel body 3 can be constrained and fixed to the top of the support block 8. The limiting rod 12 slides inside the limiting block 13, and the rotating rod 903 and the second arc block 902 are rotatably connected, which can prevent the second arc block 902 from rotating with the rotating rod 903 when it moves. The two support blocks 8 are connected by the connecting plate 11, so that the electric telescopic rod and the support block 8 can remain stable.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, a connecting frame 5 is fixedly connected to the front side of the support plate 4, and a triangular block 6 is fixedly connected to the surface of the connecting frame 5. The rear side of the triangular block 6 contacts the front side of the support block 8.

[0036] Specifically, such as Figure 2 and Figure 3 As shown, lifting plates 10 are fixedly connected to opposite sides of the two support blocks 8, and a second electric telescopic rod 2 is fixedly connected to the surface of the support frame 1. There are two second electric telescopic rods 2, and the bottom of the telescopic end of the second electric telescopic rod 2 is fixedly connected to the top of the lifting plate 10.

[0037] In this embodiment: the triangular block 6 is fixedly connected to the support plate 4 through the connecting frame 5, so that the triangular block 6 remains on the ground after the support block 8 is raised, avoiding the squealing of the triangular block 6 from causing injury to the testing personnel. By simultaneously controlling the extension ends of the two second electric telescopic rods 2 to extend upward, the lifting plate 10, the support block 8 and the wheel body 3 on the top of the support block 8 can be lifted to a suitable height.

[0038] Specifically, such as Figure 2 As shown, the support plate 4 has several fixing holes 14 inside, which are evenly distributed inside the support plate 4.

[0039] Specifically, such as Figure 2 and Figure 5As shown, the front side of the triangular block 6 is chamfered. The triangular block 6, the support block 8, the first arc block 901 and the second arc block 902 are all made of magnesium-aluminum alloy.

[0040] In this embodiment: the support plate 4 has several evenly distributed fixing holes 14 inside, which can be fixed to the ground by external bolts to ensure the stability of the support frame 1 and the support block 8 during use. The triangular block 6, the support block 8, the first arc block 901 and the second arc block 902 are all made of magnesium-aluminum alloy. Magnesium-aluminum alloy has the characteristics of light weight and high strength, which not only reduces the weight of the support block 8 and the lifting burden, but also ensures sufficient strength and stability when supporting and constraining the wheel body 3.

[0041] Working principle: When the wheel body 3 needs to be moved to the top of the support block 8 for testing, the wheel body 3 is moved to the front of the triangular block 6. Then, the pull plate 705 is moved until the threaded post 702 is inserted into the pull plate 705. Then, the locking ring 703 is locked, so that the pull plate 705 is connected to the telescopic end of the first electric telescopic rod 701. Then, the telescopic ends of the two first electric telescopic rods 701 are simultaneously controlled to retract. The telescopic ends of the first electric telescopic rods 701 drive the threaded post 702 connected to their rear side to move forward, thereby pulling the pull plate 705 and the arc plate 704 fixed to the top of the pull plate 705 forward. At this time, the arc plate 704 gradually approaches the wheel body 3 until its surface contacts the wheel body 3. Since the triangular block 6 is fixed on the front connecting frame 5 of the support plate 4, When the arc plate 704 pulls the wheel body 3, the wheel body 3 can roll upwards relatively easily along the inclined surface of the triangular block 6, eventually being pulled to the top of the support block 8, so that the surface of the wheel body 3 contacts the surface of the support block 8 and the surface of the first arc block 901. Then, the rotating rod 903 is rotated. The rotating rod 903 is threadedly connected inside the fixing frame 904, and the side of the rotating rod 903 near the second arc block 902 is rotatably connected to the second arc block 902. By rotating the rotating rod 903, due to the thread action, the rotating rod 903 will push the second arc block 902 closer to the wheel body 3 along the direction of the limiting rod 12. At this time, the surfaces of the first arc block 901 and the second arc block 902 are in contact with the surface of the wheel body 3, constraining the wheel body 3 from the front and rear sides. To prevent the wheel body 3 from rolling or shifting during the inspection process, after the wheel body 3 is constrained and fixed, if it is necessary to raise the wheel body 3 to a more suitable inspection height, the two second electric telescopic rods 2 are controlled to retract. The bottom of the telescopic end of the second electric telescopic rod 2 is fixedly connected to the top of the lifting plate 10. The lifting plate 10 is fixedly connected to the opposite side of the two support blocks 8. When the second electric telescopic rod 2 retracts, it will pull the lifting plate 10 upward, thereby driving the support block 8 and the wheel body 3 placed on the support block 8 to rise synchronously. After the first arc block 901 and the second arc block 902 are constrained and fixed, the wheel body 3 is stably raised to a suitable inspection height, which facilitates various inspection tasks for inspection personnel of different heights. At this point, triangular block 6 will still be on the ground. To prevent the sharp corners of triangular block 6 from injuring the testing personnel, a chamfer is added to the front of triangular block 6 to further prevent accidental injury to workers. This solves the problem in existing patents where the slide rail has a certain height, and due to the weight of the train wheels, it is inconvenient to move the train wheels to the top of the slide rail. Furthermore, during the upward movement of the train wheels before contact with the mating parts, the round shape of the train wheels can easily cause them to roll without restraint. Once they roll, it is difficult to ensure that the mating parts can accurately and stably lift the train wheels. The support plates 4 on both sides of the bottom of the support frame 1 support the entire platform. Several evenly distributed fixing holes 14 are provided inside the support plates 4.The support plate 4 can be fixed to the ground with external bolts to ensure the stability of the support frame 1 and the support block 8 during use. The triangular block 6, support block 8, first arc block 901, and second arc block 902 are all made of magnesium-aluminum alloy. Magnesium-aluminum alloy is lightweight and has high strength, which reduces the weight of the support block 8 and the lifting burden, while ensuring sufficient strength and stability when supporting and constraining the wheel body 3. At the same time, a connecting plate 11 is fixedly connected between the rear sides of the two first electric telescopic rods 701, and the front side of the connecting plate 11 is fixedly connected to the rear side of the support block 8. This structural design enhances the stability of the connection between the first electric telescopic rod 701 and the support block 8, enabling the first electric telescopic rod 701 to work more reliably when pulling the wheel body 3.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
