The bogie stabilizing support frame, as a specialized piece of equipment supporting the bogie, plays an indispensable role in the entire maintenance process, and its performance directly affects maintenance efficiency and the safety of locomotive operation.

[0003] Currently, most diesel locomotive bogie stabilizing support frames on the market adopt a fixed structure design, relying on pre-set support components to support the bogie. The positions and dimensions of these support components are relatively fixed, and support is achieved through simple mechanical connection when supporting the bogie. When the size of the bogie wheels changes, operators need to use additional auxiliary tools, such as shims and blocks, to adjust the support height and position to ensure that the bogie can be stably supported.

[0004] However, this support method, which relies on fixed structures and auxiliary tools, is cumbersome and complicated when dealing with bogie wheels of different sizes. It not only requires a lot of manpower and time, but also makes it difficult to ensure the stability and accuracy of the support due to the addition or replacement of auxiliary tools, which greatly reduces maintenance efficiency and weakens the adaptability of the equipment to different working conditions. Utility Model Content

[0024] 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.

[0025] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides: a stable support frame for the bogie of an internal combustion locomotive, including a support plate 1, a movable plate 3 above the support plate 1, a support seat 11 above the movable plate 3, a support wheel 12 slidably connected to the upper surface of the support seat 11, and an adjustment component at the bottom of the support wheel 12.

[0026] The adjustment assembly includes a locking block 18, which slides inside the support wheel 12 and the support base 11 under the drive of the connecting rod 16. When the locking block 18 slides into the corresponding position of the support base 11, it fixes the support wheel 12. When the locking block 18 is fully retracted into the support wheel 12, the support wheel 12 can slide freely for easy position adjustment. The locking block 18 is slidably connected inside the support wheel 12. A rotating rod 15 is rotatably connected inside the support wheel 12. One end is fixedly connected to a knob 14, and the other end is fixed to a turntable 19. The turntable 19 rotates under the drive of the knob 14, thereby causing the turntable 19 to rotate inside the support wheel 12. The top of the rotating rod 15 is fixedly connected to the knob 14, and the bottom of the rotating rod 15 is fixedly connected to the turntable 19, which is installed at the bottom of the rotating rod 15 and rotatably connected to the support wheel 12. Its rotation is achieved by rotating both ends. The connecting rod 16 converts the circular motion into linear motion at one end of the connecting rod 16, driving the locking block 18 to slide. Both ends of the turntable 19 are rotatably connected to the connecting rod 16, and the two ends are rotatably connected to the turntable 19 and the locking block 18 respectively. Driven by the turntable 19, the locking block 18 is pushed to slide inside the support wheel 12 and the support base 11, realizing the switching between the fixed and unlocked states of the support wheel 12. The bottom of the support wheel 12 is fixedly connected to the slider 13. One end of the connecting rod 16 is rotatably connected to the inside of the locking block 18. The bottom of the rotating rod 15 is provided with a torsion spring 17, one end of which is fixed inside the rotating rod 15, and the other end is fixed to the bottom of the support wheel 12. When the knob 14 is rotated, it torsional storage of elastic potential energy occurs. When the knob 14 is released, it rebounds with the elastic potential energy, driving the locking block 18 to reset, realizing the automatic fixing of the support wheel 12.

[0027] Specifically, the operator drives the rotating rod 15, which is fixedly connected to the rotating knob 14, to rotate. During the rotation of the rotating rod 15, the turntable 19 installed at the bottom of the rotating rod 15 rotates synchronously inside the support wheel 12. At the same time, the torsion spring 17 connected to the bottom of the rotating rod 15 is twisted by the force. The rotation of the turntable 19 causes one end of the connecting rod 16, which is rotatably connected to both ends, to be displaced. The other end of the connecting rod 16 then drives the locking block 18, which slides inside the support wheel 12 and the support seat 11. When the locking block 18 is fully retracted into the support wheel 12, the support wheel 12 is released from its fixed restriction. The operator can pull the support wheel 12 to slide above the support seat 11 to adjust its position. After the adjustment is completed, the operator releases the knob 14. At this time, the torsion spring 17 rebounds due to its own elasticity, causing the locking block 18 to slide back into the corresponding position of the support seat 11, thereby fixing the support wheel 12 and achieving the purpose of adapting to different sizes of bogie wheels.

[0028] Reference Figure 1 - Figure 2A slider 2 is slidably connected to the inner wall of the support plate 1. A bidirectional lead screw 8 is rotatably connected inside the support plate 1 and threadedly connected to a moving block 9. Driven by a knob 10, the lead screw 8 rotates, converting rotational motion into linear motion of the moving block 9, which in turn moves the moving plate 3. A knob 10 is fixedly connected to one end of the bidirectional lead screw 8. The operator rotates the knob 10, causing the bidirectional lead screw 8 to rotate, thereby adjusting the distance between the two moving plates 3. A moving block 9 is threadedly connected to the outer wall of the bidirectional lead screw 8, and its upper surface is fixedly connected to the moving plate 3. Driven by lever 2 8, it moves inside the support disk 1, thereby causing the moving disk 3 to move relative to it. The upper surface of moving block 2 9 is fixedly connected to the lower surface of the moving disk 3, and the upper surface of slider 1 2 is fixedly connected to the lower surface of the moving disk 3. The inner wall of the moving disk 3 is provided with a moving assembly, which includes slider 2 4. The outer wall of slider 2 slidably connects to the inner wall of the moving disk 3, and the upper surface is fixedly connected to the support base 11. Sliding slider 2 4 transmits the power of moving block 1 5, drives the support base 11 to move, and guides the movement of the support base 11. The outer wall of slider 2 4 is slidably connected to the inner wall of the moving disk 3. The movable disk 3 is internally connected to a bidirectional lead screw 6, which is threadedly connected to a movable block 5. Driven by a knob 7, the lead screw 6 rotates, converting the rotational motion into linear motion of the movable block 5, thus moving the support base 11. The outer wall of the bidirectional lead screw 6 is threadedly connected to the movable block 5, which moves relative to the support base 11 under the drive of the lead screw 6. This movement is achieved through a slider 4. A knob 7 is fixedly connected to one end of the bidirectional lead screw 6. Rotating the knob 7 causes the bidirectional lead screw 6 to rotate, adjusting the distance between the support bases 11. The slider 4 is shown on the table above. The first component is fixedly connected to the lower surface of the support base 11. The second component 4 is used to drive the support base 11 to move. The turntable 19 is rotatably connected to the bottom of the support wheel 12. The turntable 19 is used to drive one end of the connecting rod 16 to move. The outer wall of the locking block 18 is slidably connected to the inside of the support base 11. The locking block 18 is used to fix the support wheel 12. The outer wall of the third component 13 is slidably connected to the inside of the support base 11. The third component 13 is used to guide the support wheel 12. One end of the torsion spring 17 is fixedly connected to the inside of the rotating rod 15. The other end of the torsion spring 17 is fixedly connected to the bottom of the support wheel 12.

[0029] Specifically, the operator can rotate knob 10 to rotate the bidirectional lead screw 8. Since the bidirectional lead screw 8 and the moving block 9 are connected by threads, when the bidirectional lead screw 8 rotates, the moving block 9 moves inside the support plate 1 along the direction of the lead screw, thereby driving the moving plate 3, which is fixedly connected to the upper surface of the moving block 9, to move relative to each other, thus adjusting the distance between the two moving plates 3. In addition, rotating knob 7 can drive the bidirectional lead screw 6 to rotate, and the moving block 5, which is threaded to the outer wall of the bidirectional lead screw 6, moves relative to each other, thereby driving the support base 11, which is fixedly connected to the slider 4, to move relative to each other, thus flexibly adjusting the distance between the support bases 11.

[0030] Working principle: When the bogie stabilization support frame needs to be used, first drive knob 3 14 drives rotating rod 15 to rotate, thereby driving turntable 19 to rotate inside support wheel 12 through rotating rod 15. At the same time, torsion spring 17 is twisted, and then the rotation of turntable 19 drives one end of connecting rod 16 to move. Then, the other end of connecting rod 16 drives locking block 18 to slide inside support wheel 12 and support seat 11. When locking block 18 is completely moved inside support wheel 12, support wheel 12 can be pulled to slide above support seat 11 for position adjustment. After adjustment, release knob 3 14. At this time, torsion spring 17 rebounds, driving locking block 18 back to its interior for fixation, thus realizing position adjustment and adapting to bogie wheels of different sizes.

[0031] In addition, by rotating knob 10, the bidirectional lead screw 8 can be rotated, causing the moving block 9 to move inside the support plate 1, thereby causing the moving plate 3 to move relative to each other, thus adjusting the distance between the two moving plates 3. Then, by rotating knob 7, the bidirectional lead screw 6 can be rotated, causing the moving block 5 to move relative to each other, thereby causing the support base 11 to move relative to each other, thus achieving the effect of adjusting the distance between the support bases 11.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
