Description

Technical Field

[0001] The utility model relates to the field of protection systems, in particular to a coupling cover for a pump. Background Art

[0002] The coupling cover is suitable for running equipment with coupling transmission, especially in the field of chemical pumps. At present, most of the coupling covers used are non-fully enclosed structures, with large radial clearances between the rotating parts at the pump end and the motor end, which causes the rotating parts to be exposed, posing a great safety hazard to on-site operations; in addition, the non-fully enclosed coupling cover has a single frame and is mostly directly welded to the machine base, resulting in insufficient pressure bearing capacity, easy damage, unstable equipment operation, difficult disassembly, and inconvenient equipment maintenance.

[0003] A Chinese patent (publication number: CN 218882821 U) discloses a fully enclosed coupling cover for chemical centrifugal pumps, which achieves a fully enclosed structure by setting a bent upper plate and side plates; using a bracket to increase stability; using an openable upper cover to facilitate equipment inspection and maintenance; and using an active connection between the bracket and the fixed plate to achieve overall disassembly. Although it is provided with an openable upper cover, it is also blocked by the upper cover, the front plate, and the bent upper plate, making it inconvenient to observe the transmission position of the coupling it protects, and it is impossible to observe the working condition of the transmission position of the coupling in real time; and when the upper cover is opened for observation when the coupling is in working state, the top of the coupling is in an unshielded and unprotected state, which is easy to cause external objects to be involved or liquids carried on the coupling to be thrown out, and there are certain safety hazards in the high-speed rotating coupling. Utility Model Content

[0004] The purpose of the utility model is to provide a coupling cover for a pump in view of the defects in the prior art. The upper cover is rotatably mounted on a support plate, and the upper cover can be opened and closed for inspection and maintenance. A window is arranged on the upper cover and a transparent protective plate is installed. The working state of the coupling in the coupling cover for the pump can be observed through the transparent protective plate without opening the upper cover. The real-time observation needs are met in a good protective state, thereby improving the protective effect and reducing safety hazards.

[0005] In order to achieve the above purpose, the following technical solutions are adopted:

[0006] A coupling cover for a pump, comprising:

[0007] The support plates are provided with two spaced apart from each other, and the bottom of the support plates are provided with feet;

[0008] The upper cover includes an arched bending plate. One side of the bending plate is rotatably connected to the top end of one of the support plates, and the other side can be detachably connected to the other support plate through a buckle, so that the upper cover and the support plates jointly form a structure with an N-shaped cross-section. A visual window is provided on the upper cover, and a transparent plate is installed on the upper cover to block the visual window.

[0009] Further, a protective area for accommodating the coupling is formed inside the structure with an N-shaped cross-section. A bracket is provided inside the protective area, and the bracket is connected to the support plate.

[0010] Further, the section of the bracket extending to the support plate forms an arched section. When the bending plate is connected to the other support plate through a buckle, the arched section abuts against the bending plate to form a support.

[0011] Further, there are multiple brackets, which are arranged at intervals in sequence along the axial direction of the coupling accommodated in the protective area and are connected to two relatively spaced support plates.

[0012] Further, telescopic plates are respectively distributed at both ends of the bending plate. The telescopic plates are arched, and long circular holes are provided on the telescopic plates. The long circular holes are matched with fasteners and installed on the bending plate, and the fasteners slide relative to the long circular holes to change the relative position between the telescopic plate and the bending plate.

[0013] Further, the convex surface of the telescopic plate fits the concave surface of the bending plate, and the sliding direction of the long circular hole is from one end of the bending plate to the other end.

[0014] Further, two long circular holes are provided on the telescopic plate, and the long circular holes are respectively matched with fasteners.

[0015] Further, the buckle includes a hook and a lock. The lock is installed on the support plate, the hook is installed on the upper cover, and the lock and the hook are detachably matched.

[0016] Further, the bending plate is matched with two spaced buckles, and the visual window is located between the two buckles.

[0017] Further, a handle is installed on the upper cover, and one side of the bending plate is connected to the support plate through a hinge to form a rotational connection.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] Aiming at the problem that it is inconvenient to observe the working state of the internal coupling in real time in the current coupling cover, the present utility model sets the upper cover to be rotatably installed on the support plate, and the upper cover can be opened and closed for inspection and maintenance. A window is provided on the upper cover and a transparent protective plate is installed, so that the working state of the coupling in the pump coupling cover can be observed through the transparent protective plate without opening the upper cover, meeting the real-time observation requirements under good protection conditions, improving the protection effect and reducing potential safety hazards.

[0020] In the present utility model, a telescopic plate is installed on the bent plate of the upper cover. By using the telescopic plate to extend the length of the bent plate, the protection range of the entire upper cover is increased, so as to meet the protection requirements of couplings with larger axial dimensions and improve the applicability.

[0021] In the present utility model, both the telescopic plate and the bent plate are arched structures. Compared with the existing protection structure, the shrinkage part is reduced, and the operating condition of the coupling can be observed from both ends of the pump coupling cover, improving the visual range.

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application.

[0028] Although the current coupling protective cover is provided with a top cover that is convenient for opening and closing, it also affects the real-time observation of the inside of the coupling, making it difficult to intuitively grasp the working state of the coupling. Based on this, this embodiment provides a pump coupling cover, which is provided with an upper cover 6 that can be flipped, and forms a protective structure for enclosing the coupling in combination with the support plate 2. The upper cover 6 can be opened by rotation for easy maintenance and inspection; a transparent plate is installed at the visual window 7 position of the upper cover 6 for blocking. This can not only meet the requirements of shielding protection, but also use the transparent plate to observe the coupling in real time and timely grasp the operating state of the coupling.

[0029] See Figure 1, the coupling cover for pumps mainly includes a support plate 2 and an upper cover 6. Among them, there are two relatively spaced support plates 2. At the bottom of the support plate 2, there are feet 1. Through the feet 1, the support plate 2 can be fixed on the ground to keep the support plate 2 stable. Between the two spaced support plates 2, the coupling to be protected can be accommodated.

[0030] The upper cover 6 includes an arched bending plate. One side of the bending plate is rotatably connected to the top end of one of the support plates 2, and the other side can be detachably connected to the other support plate 2 through a buckle 8, so that the upper cover 6 and the support plate 2 jointly form a structure with an n-shaped cross-section, and the upper cover 6 realizes protection from above the coupling.

[0031] During the operation of the equipment, real-time observation of the working state of the coupling is an important means to ensure the stable operation of the equipment. Although the maintenance and protection of the coupling can be achieved by opening and closing the upper cover 6, when opening the upper cover 6 for observation, it is necessary to stop the rotation of the coupling and the connected motor shaft and pump shaft, resulting in the problem of inconvenient observation. In this embodiment, a visual window 7 is provided on the upper cover 6, and a transparent plate is installed on the upper cover 6 to block the visual window 7, and it is possible to observe the coupling position in the protection area from the position of the visual window 7 through the transparent plate.

[0032] The opening and closing operation of the upper cover 6 is simple and convenient, facilitating inspection and maintenance. By providing a visual window 7 on the upper cover 6, the problem of observing the working state of the coupling without opening the upper cover 6 is directly solved, effectively meeting the requirements of real-time observation and convenient maintenance of the pump coupling under the premise of ensuring safety.

[0033] Two relatively spaced support plates 2 are adopted, and are respectively fixed by the feet 1 from both sides of the coupling to form a stable support structure, ensuring the overall stability of the pump coupling cover. There are feet 1 at the bottom of the support plate 2, and bolt holes are provided in the feet 1, and the feet 1 can be fixed through anchor bolts, etc., so as to realize the fixation of the position of the support plate 2, enhance the connection strength between the support plate 2 and the ground, and prevent the pump coupling cover from shaking or shifting during use.

[0034] The upper cover 6 is designed as an arched bending plate. One side is connected to one of the support plates 2 by a rotational connection method, and the other side is detachably connected to the other support plate 2 through a buckle 8. A transparent protective plate is installed on the visual window 7, which not only ensures the clarity of the observation line of sight but also plays a protective role, preventing external objects or personnel from accidentally touching the coupling and improving safety.

[0035] The openable and closable design of the upper cover 6 makes the maintenance and repair work more convenient. When more in-depth inspection or repair is required, it is only necessary to open the upper cover 6, without disassembling the entire cover, greatly saving time and labor costs.

[0036] As Figure 2 and Figure 3 shown, a protective area for accommodating a coupling is formed inside the structure of the n-shaped cross-section. The protective area is a channel of the n-shaped cross-section, and the axis of the coupling is distributed along the axial direction of the channel. A bracket 3 is provided inside the protective area, and the bracket 3 is connected to the support plate 2. The bracket 3 is arranged inside the structure of the n-shaped cross-section to reinforce the support plate 2, ensure the stability of the support plate 2, and provide stable protection for the coupling.

[0037] In this embodiment, the two sides of the bent plate refer to the two sides with the axis of the coupling as the dividing line. One end of the arched bent plate along its arched trajectory is one side of the bent plate, and the other end of the arched bent plate along its arched trajectory is the other side of the bent plate.

[0038] The section of the bracket 3 extending to the support plate 2 forms an arched section. When the bent plate is connected to another support plate 2 through the buckle 8, the arched section abuts against the bent plate to form a support. The connection with the buckle 8 enhances the connection strength between the upper cover 6 and the support plate 2, preventing the upper cover 6 from accidentally opening due to external force in the closed state. The overall stability and safety of the coupling cover are improved.

[0039] The brackets 3 are arranged at intervals in sequence along the axial direction of the coupling accommodated in the protective area, and are connected to two relatively spaced support plates 2; the multiple spaced brackets 3 can provide support points distributed at multiple positions for the closed upper cover 6, ensuring that it can be stably supported at different positions.

[0040] As Figure 1 and Figure 2 shown, telescopic plates 5 are respectively distributed at both ends of the bent plate. The telescopic plates 5 are arched, and long circular holes are provided on the telescopic plates 5. The long circular holes cooperate with fasteners 4 and are installed on the bent plate. The fasteners 4 slide relative to the long circular holes to change the relative position between the telescopic plates 5 and the bent plate.

[0041] The convex surface of the telescopic plate 5 fits the concave surface of the bent plate, and maintains the fitting state to meet the shielding requirement. The sliding direction of the long circular hole is from one end of the bent plate to the other end, so that the telescopic plate 5 can expand and contract along the axial direction of the coupling, increasing or shortening the length of the entire upper cover 6 in the axial direction of the coupling, and improving the adaptability and flexibility of the coupling cover.

[0042] Two long circular holes are provided on the telescopic plate 5, and the long circular holes are respectively matched with fasteners 4. More stable fixing effects are provided by the two fasteners 4 to prevent the telescopic plate 5 from shifting during use. During adjustment, the fasteners 4 can be loosened first, the position of the telescopic plate 5 is adjusted, and the fasteners 4 are tightened after adjustment for fixation. In this embodiment, the fasteners 4 can be bolts, screws, etc., or magnets can also be used to reinforce the connection between the telescopic plate 5 and the bent plate to improve its connection stability.

[0043] The buckle 8 includes a hook and a latch. The latch is installed on the support plate 2, and the hook is installed on the upper cover 6. The latch and the hook are detachably engaged. A simple and quick way to open and close the upper cover 6 is provided, which is convenient for inspection and maintenance. The convenience and practicality of the coupling cover are improved.

[0044] The bent plate is provided with two buckles 8 arranged at intervals, and the visual window 7 is located between the two buckles 8, which ensures that while maintaining the stable connection of the upper cover 6, it does not affect observing the state of the coupling through the visual window 7. The structural layout of the upper cover 6 is optimized, and the overall aesthetics and practicality are improved.

[0045] A handle 9 is installed on the upper cover 6, and one side of the bent plate is connected to the support plate 2 through a hinge 10. A convenient way to open and close the upper cover 6 is provided, and at the same time, the rotational connection between the upper cover 6 and the support plate 2 is ensured to be stable and reliable. The usability and reliability of the pump coupling cover are improved.

[0046] The specific embodiments of the utility model have been described in detail above, but they are only examples, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modification or substitution of the utility model is also within the scope of the utility model. Therefore, equivalent transformations, modifications, improvements, etc. made without departing from the spirit and principles of the utility model should all be covered within the scope of the utility model.
