[0002] The integral wheel of a locomotive is a key component of the locomotive wheelset. It has a special structure with a flange on the inner side.

[0003] During the maintenance and processing of integral wheelsets, frequent hoisting operations are required. Due to the special structure of the integral wheel, which has a flange on the inner side, it can be placed in two positions: flange facing down and flange facing up.

[0004] While existing integral wheel lifting devices can lift integral wheels, they often cannot adapt to two different placement states, requiring the use of two different lifting devices for lifting. This is cumbersome and significantly impacts work efficiency. Especially when the integral wheel is in the rim-up position, the contact surface for lifting is very small, and the anti-slip effect is poor, making it easy for the workpiece to fall off. This not only damages the workpiece but also poses a serious threat to the safety of employees, causing many inconveniences for the inspection and processing of integral wheels. Therefore, a horizontal integral wheel lifting device is proposed to solve the above problems. Utility Model Content

A bidirectional threaded rod is rotatably connected to one side between the first mounting base and the second mounting base, and a guide rod is fixedly connected to the other side between the first mounting base and the second mounting base. An adjustment clamp is provided between the bidirectional threaded rod and the guide rod, and an anti-slip clamping assembly is provided on the surface of the adjustment clamp.

[0010] As a further description of the above technical solution:

[0011] There are two adjusting clamps, which are mirror images of each other along the central axis of the bidirectional threaded rod and the guide rod.

[0012] As a further description of the above technical solution:

[0013] The anti-slip clamping assembly includes a fixed base and an anti-slip clamping plate. The outer wall of the fixed base is fixedly connected to the outer surface of the adjusting clamping base, and the inner side of the fixed base is fixedly connected to a telescopic locking pin.

[0031] 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.

[0032] Reference Figures 1-3This utility model provides an embodiment of an integral wheel-type lifting device, including a sling 1. The sling 1 serves as a load-bearing connecting component of the lifting device, used to connect the lifting equipment to the hook structure below and transmit lifting force. A hook stiffener 2 is attached to the bottom end of the sling 1. The hook stiffener 2 connects the sling 1 and the hook U-shaped plate 3, while also enhancing the overall structural strength of the lifting device and dispersing stress during lifting. The hook U-shaped plate 3 is fixedly connected to the inner side of the hook stiffener 2. The hook U-shaped plate 3 is one of the main supporting components that directly contacts the object being lifted. Its U-shaped structure facilitates initial hooking and bearing of the object. An adjustment component 5 is provided on the surface of the hook stiffener 2. The adjustment component 5 can adjust the... The adjustment assembly 5 is adjusted according to the size of the object being lifted to achieve stable clamping of objects of different sizes. It includes a first mounting base 51 and a second mounting base 52. The first and second mounting bases 51 and 52 provide the mounting foundation and support for other components of the adjustment assembly 5, ensuring the stability of each component's installation. The outer wall of the first mounting base 51 is fixedly connected to one side of the outer surface of the hook stiffener 2, and the outer wall of the second mounting base 52 is fixedly connected to the other side of the outer surface of the hook stiffener 2. The second mounting base 52 and the first mounting base 51 are symmetrically mounted on the hook stiffener 2, together forming the mounting frame of the adjustment assembly 5. A double-sided rotatable connection is provided between the first mounting base 51 and the second mounting base 52 on one side. The threaded rod 53, a double-sided threaded rod 53, can drive the adjusting clamp 55 to move relative to or towards each other by rotation. It is the core transmission component for realizing the adjustment function. A guide rod 54 is fixedly connected to the other side between the first mounting base 51 and the second mounting base 52. The guide rod 54 guides the movement of the adjusting clamp 55, preventing the adjusting clamp 55 from deviating during movement and ensuring the accuracy of its movement trajectory. An adjusting clamp 55 is provided between the double-sided threaded rod 53 and the guide rod 54. The adjusting clamp 55 is used to clamp and fix the suspended object in conjunction with the hook U-shaped plate 3. There are two adjusting clamps 55 in total. The two adjusting clamps 55 work together to clamp the object from both sides. The clamping mechanism enhances clamping stability. Two adjusting clamps 55 are mirror-image positioned along the central axis of the bidirectional threaded rod 53 and the guide rod 54. This mirror-image arrangement allows the two adjusting clamps 55 to move symmetrically and synchronously, ensuring the symmetry and balance of the object clamping. One side of the inner wall of the adjusting clamp 55 is threaded to the outside of the bidirectional threaded rod 53. Through this threaded connection, the rotation of the bidirectional threaded rod 53 is converted into linear movement of the adjusting clamp 55. The other side of the inner wall of the adjusting clamp 55 is movably connected to the outside of the guide rod 54. This movable connection does not affect the movement of the adjusting clamp 55 with the bidirectional threaded rod 53, and it maintains a stable direction of movement under the constraint of the guide rod 54.

[0033] Reference Figure 1 , Figure 3 and Figure 4The surface of the adjusting clamp 55 is provided with an anti-slip clamping component 6. The anti-slip clamping component 6 increases the friction between the adjusting clamp 55 and the object being lifted, preventing the object from slipping during lifting and improving the safety of the lifting equipment. The anti-slip clamping component 6 includes a fixed base 61 and an anti-slip clamping plate 63. The fixed base 61 is the mounting base of the anti-slip clamping component 6, and the anti-slip clamping plate 63 is in direct contact with the object being lifted to achieve the anti-slip clamping function. The outer wall of the fixed base 61 is fixedly connected to the outer surface of the adjusting clamp 55, so that the fixed base 61 and the adjusting clamp 55 are firmly connected to ensure anti-slip. The clamping assembly 6 can move together with the adjusting clamp 55. The inner side of the fixed base 61 is fixedly connected to the telescopic latch 62. The telescopic latch 62 is used to quickly install and fix the anti-slip clamp 63. Its telescopic feature facilitates operation. The anti-slip clamp 63 is movably engaged on the inner side of the telescopic latch 62. The movable engagement method facilitates the disassembly and replacement of the anti-slip clamp 63. When the anti-slip clamp 63 is worn, it can be replaced in time. A locking hole 64 is provided on the outer side of the anti-slip clamp 63. The locking hole 64 cooperates with the telescopic latch 62 to achieve precise locking of the anti-slip clamp 63. To prevent loosening during use, the telescopic end of the telescopic pin 62 is movably engaged with the inner wall of the locking hole 64. This engagement structure allows for quick and easy fixation of the anti-slip clamp 63, ensuring reliable connection. An anti-slip pad 4 is fixedly connected to the inner side of the locking hole 64. This anti-slip pad 4 further enhances the friction when in contact with the suspended object, improving the anti-slip effect in conjunction with the anti-slip clamp 63. An anti-slip pad 4 is also fixedly connected to the inner wall of the hook U-shaped plate 3. The anti-slip pad 4 on the inner wall of the hook U-shaped plate 3 increases the contact surface when an object is placed within the U-shaped structure. Friction prevents objects from slipping. The inner walls of the hook U-shaped plate 3 and the adjusting clamp 55 are both grooved. The grooves provide installation space for the anti-slip clamp 63. The size fit ensures that the anti-slip clamp 63 can form a flat clamping surface with the hook U-shaped plate 3 and the adjusting clamp 55 after installation, improving clamping stability. The inner wall of the groove is matched with the outer wall of the anti-slip clamp 63. The surface of the anti-slip pad 4 is provided with anti-slip ridges. The anti-slip ridges can increase the friction coefficient between the anti-slip pad 4 and the suspended object, further enhancing the anti-slip performance and ensuring the safety and stability of the lifting process.

[0034] Working principle: In the maintenance and lifting operation of the integral wheel of the locomotive, when using this integral wheel horizontal lifting tool, the lifting equipment is first connected through the sling 1, and the lifting tool is suspended as a whole. The sling 1 transmits the lifting force of the lifting equipment to the hook stiffener 2, and the hook stiffener 2 then distributes the force to the inner hook U-shaped plate 3, preparing to support the integral wheel. When it is necessary to lift the integral wheel, depending on its placement state during maintenance, with the wheel rim facing down or up, the integral wheel is placed in the U-shaped structure of the hook U-shaped plate 3. The anti-slip pad 4 on the inner wall of the hook U-shaped plate 3 contacts the integral wheel with its anti-slip ridges, initially increasing the friction on the arc surface of the integral wheel to prevent it from sliding.

[0035] Subsequently, the adjustment component 5 is operated, and the bidirectional threaded rod 53 between the first mounting base 51 and the second mounting base 52 is rotated. Since the two adjustment clamps 55 are mirror images of the central axis of the bidirectional threaded rod 53 and the guide rod 54, and one side of the inner wall of the adjustment clamp 55 is threadedly connected to the bidirectional threaded rod 53, and the other side is movably connected to the guide rod 54, when the bidirectional threaded rod 53 is rotated, the two adjustment clamps 55 will move relative to each other along the bidirectional threaded rod 53 under the guidance of the guide rod 54, and gradually approach the two sides of the integral wheel. Especially when the wheel rim is facing upward, it can accurately fit the inner side of the rim and other special parts.

[0036] As the adjusting clamp 55 moves, the anti-slip clamping component 6 on its surface also approaches the integral wheel. When the adjusting clamp 55 moves to the appropriate position, the anti-slip clamp 63 contacts the integral wheel, and the telescopic end of the telescopic pin 62 on the inner side of the fixing seat 61 is inserted into the locking hole 64 on the outer side of the anti-slip clamp 63, thus locking the anti-slip clamp 63 securely. At this time, the anti-slip pad 4 on the inner side of the anti-slip clamp 63 further enhances the friction with the integral wheel, ensuring stable clamping of the integral wheel even when the wheel rim is facing upwards and the contact surface is small.

[0037] Throughout the process, the adjustment component 5 adapts and adjusts to the integral wheels of different specifications, while the anti-slip clamping component 6 ensures that the integral wheels will not slip during the maintenance and lifting process through multiple anti-slip structures. Finally, the integral wheels are safely lifted under the lifting of the sling 1, meeting the needs for movement and transfer of the integral wheels during maintenance operations.

[0038] 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.
