Description

Technical Field

[0001] This utility model relates to the field of coupling protection technology, and in particular to a coupling protection device. Background Technology

[0002] Couplings, as key components connecting different parts in mechanical transmission systems, play a vital role in transmitting torque and compensating for misalignment in industrial production and mechanical equipment operation. However, due to safety hazards such as component loosening and parts splashing during high-speed operation, and the susceptibility of couplings to dust and foreign objects intrusion in the working environment, their performance deteriorates or even causes equipment failure. Therefore, coupling protection devices have become important auxiliary components to ensure the safe and stable operation of equipment and extend its service life. With the continuous improvement of industrial automation, higher requirements are placed on the protective performance, adaptability, and convenience of protection devices.

[0003] Currently, most common coupling protection devices on the market adopt a fixed structure, usually consisting of a metal shell and bolt fasteners. The technical principle of this type of protection device is to use bolts to tightly fix a pre-designed metal shell around the coupling to form a closed protective space, thereby blocking foreign objects from entering and preventing parts from falling off and causing damage when the coupling is running. Its structure is simple and the cost is low, which can meet the protection needs of conventional couplings to a certain extent.

[0004] However, existing fixed coupling protection devices have significant limitations. Since their housing dimensions and height are fixed during manufacturing, they cannot be flexibly adjusted according to the size and height of different coupling specifications. When faced with couplings of different models and specifications, it is often necessary to replace them with specific protective devices that match them. This not only increases the company's equipment maintenance costs but also reduces work efficiency. Moreover, if the specifications of newly purchased couplings do not match the existing protective devices, it is necessary to customize or purchase new protective devices. This greatly limits the versatility and applicability of the protective devices and makes it difficult to meet the diverse needs of industrial production. Therefore, a coupling protection device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a coupling protection device, which aims to improve the problem that the existing technology has a relatively fixed height and cannot adapt to couplings of different specifications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A coupling protection device includes a base, a fixing plate fixedly connected to the top of the base, a protective cover slidably connected inside the fixing plate, an adjustment component provided on the outer wall of the fixing plate, and a splicing component provided at the bottom of the base.

[0008] The adjustment assembly includes a locking pin, the outer wall of which is slidably connected to the inside of the protective cover. A fixed outer shell is fixedly connected to the outer wall of the fixed plate. A sliding column is slidably connected inside the fixed outer shell. A pull ring is rotatably connected inside the sliding column. A limiting disc is fixedly connected to one end of the sliding column. The other end of the limiting disc is fixedly connected to one end of the locking pin. A spring is sleeved on the outer wall of the sliding column. One end of the spring is fixedly connected to the inner wall of the fixed outer shell. The other end of the spring is fixedly connected to the outer wall of the limiting disc.

[0009] As a further description of the above technical solution:

[0010] The splicing assembly includes a retaining ball, the outer wall of which is slidably connected to the interior of another base.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the base is fixedly connected to a connecting shell, and a limiting groove is provided inside the base.

[0013] As a further description of the above technical solution:

[0014] The connecting housing has a sliding groove inside, and the outer wall of the ball is slidably connected to the inside of the sliding groove.

[0015] As a further description of the above technical solution:

[0016] A push rod is slidably connected inside the connecting housing. One end of the push rod is fixedly connected to a push plate, and the outer wall of the push plate is slidably connected inside the limiting groove.

[0017] As a further description of the above technical solution:

[0018] A limiting ring is fixedly connected to the outer wall of the push rod, and the outer wall of the limiting ring is slidably connected inside the connecting housing.

[0019] As a further description of the above technical solution:

[0020] One end of the push rod is fixedly connected to a conical block, and the other end of the conical block is fixedly connected to a limit post.

[0021] As a further description of the above technical solution:

[0022] A second spring is fitted on the outer wall of the push rod. One end of the second spring is fixedly connected to the inner wall of the connecting housing, and the other end of the second spring is fixedly connected to the outer wall of the limiting ring.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the locking pin moves by pulling the pull ring. When the pull ring is pulled, the pull ring drives the sliding pin and the limiting disc, and in conjunction with the spring, the locking pin slides inside the protective cover. This allows for convenient adjustment of the height of the protective cover to accommodate different specifications of couplings, solving the problem that a fixed height cannot accommodate different specifications of couplings and improving the applicability of the protection.

[0025] 2. In this utility model, the ball moves by pushing the push plate. When the push plate is pushed, it drives the push rod and the limiting post, and in conjunction with the second spring, the ball slides inside the groove, thus facilitating the splicing of the two protective devices. This makes it convenient to protect the extended coupling, solves the problem that the two protective devices cannot be spliced ​​together and thus cannot adapt to different lengths, and improves the stability of the protection.

[0033] 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.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a coupling protection device, including a base 1. The base 1 provides the foundation for supporting and fixing the entire protection device. It is usually made of high-strength cast iron, which has good rigidity and stability and can withstand certain external impacts and vibrations. This is common knowledge and will not be described in detail here. A fixing plate 2 is fixedly connected to the top of the base 1 by welding or bolting. The fixing plate 2 has a rectangular frame structure with smooth sliding tracks inside for sliding connection with the protective cover 3. The protective cover 3 is made of stainless steel, which has good corrosion resistance and strength and can effectively block external dust, debris, and liquids from corroding the coupling. The protective cover 3 is slidably connected inside the fixing plate 2. An adjustment component is provided on the outer wall of the fixing plate 2, and a splicing component is provided at the bottom of the base 1.

[0035] The adjustment assembly includes a locking post 8, which is a cylindrical structure with a polished outer wall to ensure smooth sliding inside the protective cover 3. The outer wall of the locking post 8 is slidably connected to the inside of the protective cover 3. A fixed outer shell 4 is fixedly connected to the outer wall of the fixed plate 2. A sliding post 6 is slidably connected inside the fixed outer shell 4. The sliding post 6 is a solid metal rod with a thread at one end for rotatable connection with a pull ring 5. A pull ring 5 is rotatably connected inside the sliding post 6. The pull ring 5 is an annular metal part with an anti-slip surface for easy operation. A limiting disc 9 is fixedly connected to one end of the sliding post 6, and the other end of the limiting disc 9 is fixedly connected to one end of the locking post 8. A spring 7 is sleeved on the outer wall of the sliding post 6. One end of the spring 7 is fixedly connected to the inner wall of the fixed outer shell 4, and the other end of the spring 7 is fixedly connected to the outer wall of the limiting disc 9.

[0036] Specifically, in actual industrial production scenarios, couplings come in various specifications and have significant height differences. When it is necessary to protect couplings of different heights, the operator can pull the pull ring 5. After the pull ring 5 is subjected to force, it drives the sliding column 6 to slide within the corresponding track. The movement of the sliding column 6 further drives the connected limiting disc 9 to move. At this time, the limiting disc 9 will compress the spring 7, and the locking column 8 will also slide out from inside the protective cover 3 along with the movement of the sliding column 6 and the limiting disc 9. In this way, the protective cover 3 can slide freely inside the fixed plate 2, thereby achieving height adjustment. When the appropriate height is reached, the operator releases the pull ring 5, and the spring 7 will rebound due to the loss of external compression, driving the locking column 8 back to its original position. The locking column 8 will re-engage the protective cover 3, keeping its height fixed, thus adapting well to couplings of different heights.

[0037] Reference Figure 1 , Figure 4 and Figure 5 The splicing assembly includes a locking ball 17, which is a solid metal sphere, typically made of stainless steel. This material has good hardness and wear resistance, ensuring it is not easily damaged during long-term use. The outer wall of the locking ball 17 is slidably connected to a corresponding slot inside another base 1. The locking ball 17 is used to engage with the slot of the other base 1 during splicing, thereby firmly connecting the two protective devices together and preventing loosening or separation during use, ensuring the stability of the protective devices after splicing. The outer wall of the locking ball 17 is slidably connected to the inside of the other base 1. A connecting shell 12 is fixedly connected to the outer wall of the base 1. A limiting groove 11 is opened inside the base 1, and a sliding groove 15 is opened inside the connecting shell 12. The outer wall of the locking ball 17 is slidably connected to the inside of the sliding groove 15. A push rod 13 is slidably connected inside the connecting shell 12. A push plate 10 is fixedly connected to one end of the push rod 13. The push plate 10 is a circular metal plate, and its outer wall is slidably connected to the inside of the limiting groove 11. When the push plate 10 is pushed, the push plate 10 moves linearly in conjunction with the push rod 13, thereby driving the subsequent components to move. The outer wall of the push plate 10 is slidably connected to the inside of the limiting groove 11. The outer wall of the push rod 13 is fixedly connected to the limiting ring 19. The outer wall of the limiting ring 19 is slidably connected to the inside of the connecting shell 12. One end of the push rod 13 is fixedly connected to the conical block 18. The other end of the conical block 18 is fixedly connected to the limiting post 16. The outer wall of the push rod 13 is fitted with a second spring 14. One end of the second spring 14 is fixedly connected to the inner wall of the connecting shell 12. The other end of the second spring 14 is fixedly connected to the outer wall of the limiting ring 19.

[0038] Specifically, in industrial production, couplings come in various lengths. When encountering long couplings, a single protective device often cannot meet the protection requirements. In this case, it is necessary to splice two protective devices together. The operator pushes the push plate 10, which, under pressure, moves the connected push rod 13. The movement of the push rod 13 causes the limiting ring 19 to move as well. During this movement, the limiting ring 19 compresses the second spring 14. Simultaneously, the push rod 13 also moves the conical block 18, which pushes the limiting post 16, thereby releasing the restriction on the retaining ball 17 and allowing it to slide freely within the slide groove 15. At this point, the operator can slide the connecting housing 12 into the other base 1. After the connecting housing 12 has slid to the appropriate position, the push plate 10 is released. The second spring 14, freed from external compression, rebounds, pushing the retaining ball 17 into the base 1, thus fixing the two protective devices together and completing the splicing. In this way, the protective device can adapt to couplings of different lengths, while maintaining good stability after splicing, providing reliable protection for the coupling.

[0039] Working principle: When protecting couplings of different heights, pull ring 5 can be pulled, which drives slide pin 6 to slide. Then, slide pin 6 drives limit disc 9 to move, compressing spring 7 and causing locking pin 8 to slide out from inside the protective cover 3. The protective cover 3 can then slide inside the fixed plate 2 to adjust its height. After adjusting to the appropriate height, release pull ring 5. Spring 7 will rebound and drive locking pin 8 back to its original position to lock the protective cover 3 and keep the height fixed, thus adapting to different couplings.

[0040] In addition, when a longer protective device is required, the two devices can be spliced ​​together. Pushing the push plate 10 moves the push rod 13, which in turn moves the limiting ring 19, compressing the second spring 14. The push rod 13 then moves the conical block 18, which in turn moves the limiting post 16, thereby releasing the limiting of the ball 17 and allowing it to slide inside the slide groove 15. This allows the connecting housing 12 to slide into the other base 1. Then, the push plate 10 is released, and the second spring 14 rebounds, pushing the ball 17 to slide into the base 1 for fixation, thus completing the splicing and adapting to couplings of different lengths while maintaining their stability.

[0041] 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.
