Description

Technical Field

[0001] This utility model relates to the field of coupling installation technology, and more specifically, to a coupling installation tool. Background Technology

[0002] A coupling, also known as a shaft coupling, is a mechanical component used to securely connect the driving and driven shafts in different mechanisms, enabling them to rotate together and transmit motion and torque. It is sometimes also used to connect shafts to other parts (such as gears and pulleys). It is usually composed of two halves, each connected by a key or tight fit to one end of the shaft, and then joined together in some way. Couplings can also compensate for misalignment (including axial, radial, angular, or combined misalignment) between the two shafts caused by manufacturing or installation inaccuracies, deformation during operation, or thermal expansion; and can also mitigate shocks and absorb vibrations.

[0003] Currently, during routine maintenance and coupling replacement of pump equipment, most couplings are quite heavy and round, making them inconvenient to grip. In the past, installation and installation were carried out by one person wearing a glove and lifting the coupling, which posed safety hazards such as coupling slippage and injury or burns. Utility Model Content

[0004] To overcome the risks of slippage and injury, as well as burns from high temperatures, that occur when workers manually install couplings in existing technologies, this utility model provides a coupling installation tool, including a support rod and a fixing component. The support rod has handles at both ends, and the fixing component is installed at the center of the support rod. The fixing component includes a fixing frame and a limiting bolt. The two ends of the fixing frame are provided with limiting rings, and the limiting bolt is detachably installed inside the limiting rings. The side of the fixing frame away from the limiting bolt is connected to the support rod.

[0005] This application uses a limiting ring on a fixed frame and a limiting bolt detachably installed inside the limiting ring to fix the coupling. The coupling fixed on the fixed frame is moved by a support rod connected to the fixed frame and handles set at both ends of the support rod, which facilitates the installation of the coupling on the pump shaft. This avoids the risks of slippage and crushing injuries and high-temperature burns that occur when workers move the machine by hand, and standardizes the operation method of coupling installation.

[0006] Preferably, the limiting bolt is a bolt, and one end of the bolt is provided with a nut, which is used to fix the coupling.

[0007] Preferably, the fixing frame includes an L-shaped fixing part and a movable part. A limit ring is provided at one end of the fixing part and one end of the movable part. A groove is provided on the fixing part along the length direction away from the limit ring. A slider is provided at the end of the movable part away from the limit ring. The slider is movable in the groove and can be moved along the length direction of the groove. The groove in the fixing part and the slider in the movable part are matched to adjust the coupling to accommodate different sizes.

[0008] Preferably, a connecting ring is provided at the center of the support rod, and the fixing frame is fixed inside the connecting ring, which not only prevents the fixing frame from sliding but also plays a part in insulating heat.

[0009] Preferably, the handle is rectangular and symmetrical about the central axis of the support rod, which makes it easy for the operator to hold and operate.

[0010] Preferably, the outer surface of the handle is provided with an anti-scalding layer to prevent the operator from being burned.

[0011] Preferably, the surface of the heat-resistant layer is provided with anti-slip texture to prevent hands from slipping.

[0012] Preferably, both the support rod and the handle are made of threaded steel with a diameter of 10-20mm, which is inexpensive, readily available, and has high strength and good durability.

[0013] Beneficial effects:

[0014] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0015] This application uses a limiting ring on a fixed frame and a limiting bolt detachably installed inside the limiting ring to fix the coupling. The coupling fixed on the fixed frame is moved by a support rod connected to the fixed frame and handles set at both ends of the support rod, which facilitates the installation of the coupling on the pump shaft. This avoids the risks of slippage and crushing injuries and high temperature burns that occur when workers lift the coupling by hand, and standardizes the operation method of coupling installation.

[0022] This application uses a limiting ring on a fixed frame and a limiting bolt detachably installed inside the limiting ring to fix the coupling. The coupling, fixed to the fixed frame, is moved via a support rod connected to the fixed frame and handles at both ends of the support rod, facilitating its installation on the pump shaft. This avoids the risks of slippage and injury, as well as burns from high temperatures, that currently occur when workers manually move the pump. It also standardizes the coupling installation process. The specific implementation method is as follows:

[0023] like Figure 1-3 As shown, a coupling installation tool includes a support rod 1 and a fixing assembly. The support rod 1 has handles 2 at both ends. The fixing assembly is installed at the center of the support rod 1. The fixing assembly includes a fixing frame 3 and a limit bolt. The two ends of the fixing frame 3 are provided with limit rings 4 opposite each other. The limit bolt is detachably installed in the limit rings 4. The side of the fixing frame 3 away from the limit bolt is connected to the support rod 1.

[0024] This application uses a limiting ring 4 on the fixed frame 3 and a limiting bolt detachably installed in the limiting ring 4 to fix the coupling. The coupling fixed on the fixed frame 3 can be moved by the support rod 1 connected to the fixed frame 3 and the handles 2 set at both ends of the support rod 1, which facilitates the installation of the coupling on the pump shaft. This avoids the risks of slippage and crushing injuries and high temperature burns that occur when workers move the machine by hand. It also standardizes the operation method of coupling installation.

[0025] Specifically, the limiting bolt is bolt 5, and one end of bolt 5 is provided with nut 6, which is used to fix the coupling.

[0026] Specifically, the fixed frame 3 includes an L-shaped fixed part 10 and a movable part 11. A limit ring 4 is provided at one end of the fixed part 10 and one end of the movable part 11. A groove 12 is provided on the fixed part 10 along the length direction of the end away from the limit ring 4. A slider 13 is provided at the end of the movable part 11 away from the limit ring 4. The slider 13 is movable in the groove 12 along the length direction of the groove 12. The groove 12 in the fixed part 10 and the slider 13 in the movable part 11 are matched to adjust the coupling to accommodate different sizes.

[0027] Specifically, a connecting ring 9 is provided at the center of the support rod 1, and the fixing frame 3 is fixed inside the connecting ring 9, which not only prevents the fixing frame 3 from sliding, but also plays a part in insulating heat.

[0028] Specifically, the handle 2 is rectangular and symmetrical about the central axis of the support rod 1, making it easy for the operator to hold and operate.

[0029] Specifically, the outer surface of the handle 2 is provided with an anti-scalding layer 7 to prevent the operator from being burned.

[0030] Specifically, the surface of the heat-resistant layer 7 is provided with anti-slip texture 8 to prevent hands from slipping.

[0031] Specifically, both the support rod 1 and the handle 2 are made of threaded steel with a diameter of 10-20mm. The materials are inexpensive, readily available, and have high strength and good durability.

[0032] Working principle: Align the hole on the coupling with the limiting hole on the fixing part of the fixing bracket, then slide the slider to make the moving part of the fixing bracket fit tightly against the other side of the coupling, pass the bolt through the limiting hole and the coupling, and then tighten the nut at the other end to complete the fixing of the coupling. Then lift the support rod by the handle to install the coupling on the pump shaft, and then loosen the nut and remove the bolt to complete the installation of the coupling.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
