Description

Technical Field

[0001] This utility model relates to the technical field of slurry pumps, and in particular to a horizontal pipeline slurry pump. Background Technology

[0002] A horizontal pipeline slurry pump is a type of centrifugal pump used to transport slurries containing solid particles, such as slag, coal ash, and silt.

[0003] Horizontal pipeline slurry pumps are driven by a motor to rotate the pump shaft. The existing pump shaft is connected to the output end of the motor through a coupling. To prevent personnel from accidentally coming into contact with the high-speed rotating coupling and avoid dangerous accidents, and to prevent foreign objects from entering the coupling connection, a protective cover is usually installed on the outside of the coupling. However, the protective cover is fixed by bolts. When performing regular maintenance, the protective cover needs to be disassembled by unscrewing each bolt, which is time-consuming, laborious and inconvenient. Utility Model Content

[0030] 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.

[0031] This utility model provides, for example Figure 1-3 The diagram shows a horizontal pipeline slurry pump, comprising a base 1, a motor 2 fixedly mounted on the top of the base 1, and a pump body 3 fixedly mounted on the top of the base 1. The output end of the motor 2 is connected to the pump body 3 via a coupling. A protective cover 4 for protecting the coupling is provided between the motor 2 and the pump body 3. The protective cover 4 is U-shaped and can be removed directly from above the coupling during disassembly. An installation mechanism 5 is provided on the protective cover 4, including a snap-fit ​​rod 51, an elastic positioning component 52, and a secondary limiting component 53. The snap-fit ​​rod 51 is fixedly connected to the bottom end of the protective cover 4 at equal intervals. Snap-fit ​​holes are provided at equal intervals on the top end of the base 1. One end of the snap-fit ​​rod 51... The inner cavity of the snap-fit ​​hole is slidably inserted and connected; the elastic positioning component 52 is set on the protective cover 4; the secondary limiting component 53 is connected to the elastic positioning component 52. The snap-fit ​​rod 51 can limit the horizontal displacement of the protective cover 4 on the base 1, and the elastic positioning component 52 can limit the vertical displacement of the protective cover 4, so that the protective cover 4 can be stably fixed on the base 1. The secondary limiting component 53 can perform secondary positioning of the elastic positioning component 52, so as to avoid the slurry pump from generating large vibration and impact force during operation, which may cause loosening, abnormal noise or even falling off. At the same time, it is simple and convenient to disassemble and assemble, and facilitates regular maintenance in the later stage.

[0032] Specifically, the elastic positioning assembly 52 includes a sleeve 521, a pressing plate 522, a telescopic rod 523, a pull plate 524, a positioning rod 525, and a compression spring 526. The sleeve 521 is fixedly connected to both sides of the protective cover 4 at equal intervals; the pressing plate 522 is located inside the sleeve 521; one end of the telescopic rod 523 is fixedly connected to the pressing plate 522; the pull plate 524 is fixedly connected to the other end of the telescopic rod 523; multiple grooves are equidistantly provided at the top of the base 1, and the pull plate 524 is slidably inserted into the inner cavity of the grooves; a positioning hole is provided on the outer wall of the snap-fit ​​rod 51, and one end of the positioning rod 525 is fixedly connected to the pull plate 524. The other end of the positioning rod 525 passes through the groove and slides into the inner cavity of the positioning hole; the compression spring 526 is sleeved on the outside of the telescopic rod 523, one end of the compression spring 526 is fixedly connected to the extrusion plate 522, and the other end of the compression spring 526 is fixedly connected to the inner wall of the sleeve 521. The compression spring 526 is always in a compressed state, so that the extrusion plate 522 can provide a stable elastic force to the pull plate 524 on the telescopic rod 523, so that the positioning rod 525 on the pull plate 524 can be stably engaged with the positioning hole opened by the snap-fit ​​rod 51, thereby fixing the protective cover 4 on the base 1.

[0033] Furthermore, a baffle 6 is fixedly connected to the outer wall of the pull plate 524 to cover the groove. The baffle 6 can prevent mud, water and gravel from blocking the groove during the operation of the slurry pump, thus affecting its use.

[0034] Specifically, the secondary limiting component 53 includes a connecting plate 531, a limiting rod 532, a first magnet 533, and a second magnet 534. One end of the connecting plate 531 is fixedly connected to the extrusion plate 522, and adjacent connecting plates 531 are staggered. Limiting holes are equidistantly opened at the top of the protective cover 4. The limiting rod 532 passes through the connecting plate 531 and slides through the inner cavity of the limiting hole. The first magnet 533 is fixedly connected to the bottom end of the limiting rod 532. The second magnet 534 is embedded in the bottom end of the inner wall of the limiting hole. The first magnet 533 and the second magnet 534 cooperate with each other. The first magnet 533 and the second magnet 534 have opposite magnetic properties, so that the first magnet 533 and the second magnet 534 can attract each other. This allows the limiting rod 532 to be stably inserted into the interior of the limiting hole. Thus, the connecting plate 531 restricts the displacement of the telescopic rod 523 and prevents the positioning rod 525 from dislodging from the positioning hole due to the vibration of the machine operation, which would lead to unstable installation.

[0035] Furthermore, a pull ring 7 is fixedly connected to the top of the limiting rod 532 for pulling the limiting rod 532. The pull ring 7 allows the operator to pull the limiting rod 532 to disassemble the protective cover 4.

[0036] 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.
