Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically to a hoisting tool for irregularly shaped shaft fan parts. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a driven machine. It plays a role in matching speeds and transmitting torque between the prime mover and the driven machine or actuator, and its applications are extremely widespread in modern machinery.

[0003] The shaft fan is one of the most important components of a speed reducer, and its performance directly affects the reliability and lifespan of the reducer. The shaft fan of a speed reducer is a typical irregularly shaped half-shaft component, weighing up to 76 kg, making it difficult to handle manually. Currently, electromagnets are used to attach it to the surface of the forged blank, and then an overhead crane is used to lift the workpiece for turnover. During turnover, the workpiece is prone to falling off the electromagnet when subjected to external impact, posing a risk of injuring workers. To meet the needs of safe production, we propose a lifting and hoisting device for irregularly shaped shaft fan components, ensuring the safe handling and turnover of shaft fan products. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting tool for irregularly shaped shaft fan parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a lifting device, including an axial hook, a connector, and a lateral hook. The lateral hook is fixedly disposed at one end of the connector, and the end of the connector away from the lateral hook is fixedly connected to the axial hook.

[0007] Furthermore, the connector is H-shaped.

[0008] Furthermore, the axial hook includes a first connecting part, a second connecting part, and a third connecting part. One end of the first connecting part is fixedly connected to the end of the connector away from the lateral hook. The end of the first connecting part away from the connector is fixedly connected to the second connecting part. The end of the second connecting part away from the first connecting part is fixedly connected to the third connecting part.

[0009] Furthermore, the first connecting part is provided with a hoisting hole and a first weight reduction hole, the second connecting part is provided with a weight reduction groove, and the third connecting part is provided with a second weight reduction hole.

[0010] Compared with the prior art, the present invention has the following technical effects:

[0011] In this invention, the lateral hook of the lifting device supports one end of the slender shaft diameter of the shaft fan, while the axial hook engages with the crossbeam at the bottom of the shaft fan to support the other end. The shaft fan is secured to the lifting device by its own weight. After the shaft fan is placed, it can be rotated. During rotation, the shaft fan is firmly locked in place by its own weight, ensuring it will not fall off regardless of the magnitude of the impact, thus guaranteeing the safety of the workers. Overall, this lifting device has a simple structure, is easy to operate, highly reliable, and versatile, enabling the safe lifting of irregularly shaped components such as shaft fans and improving work efficiency.

[0017] 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.

[0018] Please see Figures 1 to 4 This embodiment provides a lifting tool for irregularly shaped shaft fan parts, including an axial hook 1, a connector 2 and a lateral hook 3. The connector 2 is H-shaped, the lateral hook 3 is fixedly installed at one end of the connector 2, and the axial hook 1 is fixedly installed at the end of the connector 2 away from the lateral hook 3. In this embodiment, the lateral hook 3, the axial hook 1 and the connector 2 are all fixed by welding.

[0019] Specifically, the axial hook 1 includes a first connecting portion 11, a second connecting portion 12, and a third connecting portion 13. One end of the first connecting portion 11 is fixedly connected to the end of the connector 2 away from the lateral hook 3. In this embodiment, the first connecting portion 11 and the connector 2 are fixedly connected by welding. The end of the first connecting portion 11 away from the connector 2 is fixedly connected to one end of the second connecting portion 12, and the end of the second connecting portion 12 away from the first connecting portion 11 is fixedly connected to one end of the third connecting portion 13. In this embodiment, the axial hook 1 composed of the first connecting portion 11, the second connecting portion 12, and the third connecting portion 13 is an integral structure, that is, the axial hook 1 is manufactured as a single structural component during processing.

[0020] Specifically, the first connecting part 11 has a lifting hole 4 for fixing the hook. After the workpiece is placed on this lifting device, the worker inserts the hook into the lifting hole 4 to fix it, and then the workpiece can be moved around. The first connecting part 11 also has a first weight-reducing hole 6, the second connecting part 12 has a weight-reducing groove 5, and the third connecting part 13 has a second weight-reducing hole 7. The first weight-reducing hole 6, the weight-reducing groove 5, and the second weight-reducing hole 7 are all used to reduce the weight of this lifting device.

[0021] Specifically, when using this lifting tool to lift the shaft fan, it is essential to ensure that the surfaces of the lateral hook 3 and the axial hook 1 are clean to avoid scratching the lifting surface. This lifting tool is suitable for various irregularly shaped shaft fan products. During use, the lateral hook 3 and the axial hook 1 must be properly clamped to ensure that the shaft fan is securely lifted in both the axial and circumferential directions.

[0022] Specifically, the lateral hook 3 of this lifting device supports one end of the slender shaft section of the shaft fan, while the axial hook 1 engages with the crossbeam at the bottom of the shaft fan to support the other end. The shaft fan is secured to the lifting device by its own weight. After the shaft fan is placed, it begins to rotate. During rotation, the shaft fan is firmly locked in place by its own weight, ensuring it will not fall off regardless of the magnitude of the impact, thus guaranteeing the safety of the personnel. Overall, this lifting device has a simple structure, is easy to operate, highly reliable, and versatile, enabling the safe lifting of irregularly shaped components such as shaft fans and improving work efficiency.

[0023] Specifically, the working principle of this utility model is as follows: First, lay the shaft fan flat, use the lateral hook 3 to hook the front end of the shaft fan, thereby lifting one end of the shaft fan, use the axial hook 1 to hook the positioning surface on the crossbeam at the rear end of the shaft fan (i.e., the bottom of the shaft fan), thereby lifting the other end of the shaft fan. The shaft fan is fixed on the lifting device by its own weight. After the shaft fan is placed, the workers insert the hook into the lifting hole 4 and fix it, and then start the lifting operation of the shaft fan.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
