Description

Technical Field

[0001] This utility model relates to the technical field of slurry pump equipment, and in particular to a split belt cover. Background Technology

[0002] Slurry pumps, as key equipment for conveying abrasive and corrosive slurries, are widely used in mining, metallurgy, and coal industries. Among them, slurry pumps employing the ZV drive system are highly favored in heavy-duty applications due to their significant advantages such as high transmission efficiency, large load capacity, and long service life. The ZV drive system typically includes a large pulley that transmits power to the pump body via belt drive.

[0003] Currently, to protect the drive belt and pulleys, prevent foreign objects from entering, and ensure operator safety, existing ZV drive systems generally adopt the methods described in the instruction manual. Figure 9 The image shows an integrated belt cover. The standard installation procedure for this type of belt cover is as follows: First, install the pulley onto the drive shaft, and then use a lifting device to vertically lift the integrated belt cover from directly above the pulley, so that it completely covers the pulley.

[0004] This traditional one-piece belt cover structure has significant limitations in practical applications. For small ZV drive systems with smaller pulleys and a compact overall structure, where the installation space is relatively ample, the aforementioned "top-down" installation method is still feasible.

[0005] Regarding the aforementioned technologies, when dealing with large slurry pumps with high flow rates and high lift, the diameter and width of the pulleys in their ZV drive systems increase significantly. In this situation, due to limitations in the overall equipment layout or installation space, the vertical installation height available for hoisting the belt cover from above the pulley is often insufficient. This prevents the integrated belt cover from being smoothly fitted onto the top of the pulley, causing installation difficulties. Utility Model Content

[0006] To improve the ease of installation of belt covers, this utility model provides a split-type belt cover.

[0007] This utility model provides a split-type belt cover, which adopts the following technical solution: A split-type belt cover includes two cover bodies arranged opposite to each other. Each cover body includes a support and an upper cover. One end of the support is fixed to a predetermined position, and the other end is fixedly connected to the upper cover. Each of the upper covers is provided with a set of connecting mechanisms. The connecting mechanism includes a connecting plate and a first connecting piece. Multiple first connecting pieces are fixedly connected to the connecting plate, and adjacent two first connecting pieces are fixedly connected by bolts and nuts.

[0008] Preferably, the connecting mechanism further includes a plurality of second connecting pieces, which are fixedly installed on the top of the upper cover, and adjacent second connecting pieces are fixedly connected by bolts and nuts.

[0009] Preferably, the upper cover has multiple through holes.

[0010] Preferably, a fixing plate is fixedly connected to the bottom end of the support, and the fixing plate has multiple fixing holes.

[0011] Preferably, the connecting mechanism further includes a first buffer pad, which is fixedly disposed between the two upper covers.

[0012] Preferably, the connecting mechanism further includes a second buffer pad, which is fixedly installed at the bottom end of the support.

[0013] Preferably, the connecting mechanism further includes an adjusting plate, one end of which is fixedly connected to the upper cover, and the other end of which is slidably connected to the support. The adjusting plate has multiple mounting holes, and the support has correspondingly multiple adjusting holes.

[0014] Preferably, the connecting mechanism further includes a plug plate, which is fixedly mounted on the connecting plate. A slot is provided on the connecting plate opposite to the plug plate, and the plug plate is located in the slot.

[0015] In summary, this utility model has at least one of the following beneficial technical effects: 1. By replacing the traditional one-piece cover with two opposing, side-folding covers, the installation method has been changed. During installation, it is no longer necessary to hoist it directly above the pulley; instead, the two half-covers can be closed from the side of the pulley and finally secured using a connecting mechanism. This solves the problem of installing belt covers in large ZV drives due to the large pulleys and insufficient vertical space.

[0016] 2. By adding connection points at the top of the cover, the two covers are also tightly fixed at the top, effectively preventing the top of the cover from opening or deforming due to vibration or external force, thus enhancing the overall structural stability.

[0017] 3. The through-holes create natural ventilation channels, which facilitates heat dissipation and prevents heat buildup inside the cover, thus avoiding overheating and aging of the belt or a decrease in transmission efficiency. This is especially suitable for heavy-duty applications involving continuous operation, such as slurry pumps. Operators and maintenance personnel can directly observe the belt's operation, whether it is slipping or showing abnormal wear through the through-holes, without opening the cover, enabling non-stop inspection and facilitating equipment management.

[0018] 4. The first buffer pad can effectively absorb and isolate the vibration and impact generated when the two metal covers are closed and when the equipment is running, significantly reducing operating noise and improving the working environment.

[0019] 5. The second buffer pad can effectively isolate the vibration generated by the slurry pump and transmission system from being transmitted to the equipment base through the belt cover, which helps protect the foundation and reduce the impact on surrounding equipment.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1 To be continued Figure 9 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0024] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0027] Example 1: This utility model discloses a split-type belt cover. (Refer to...) Figures 1 to 5 A split-type belt cover mainly includes two cover bodies 100, which are arranged opposite to each other. Each cover body 100 includes a support 110 and an upper cover 120. One end of the support 110 is fixed to a predetermined position, and the other end is fixedly connected to the upper cover 120. Each upper cover 120 is provided with a set of connecting mechanisms 200. The connecting mechanism 200 includes a connecting plate 210 and a first connecting piece 220. Multiple first connecting pieces 220 are fixedly connected to the connecting plate 210, and adjacent first connecting pieces 220 are fixedly connected by bolts and nuts.

[0028] By replacing the traditional one-piece cover 100 with two opposing, side-closing cover 100s, the installation method has been changed. During installation, it is no longer necessary to hoist the belt from directly above the pulley; instead, the two half-covers 100s can be closed from the sides of the pulley and finally secured by the connecting mechanism 200. This solves the problem of installing belt covers in large ZV drives due to the large pulleys and insufficient vertical space. When belt replacement or equipment maintenance is required, simply loosening the side connecting mechanism 200 allows the cover 100 to be opened to both sides, providing ample operating space and great convenience, significantly reducing maintenance time and labor costs.

[0029] Reference Figures 1 to 4 In some embodiments, the connecting mechanism 200 further includes a plurality of second connecting pieces 230, which are fixedly installed on the top of the upper cover 120. Adjacent second connecting pieces 230 are fixedly connected by bolts and nuts. By adding connection points at the top of the cover 100, the two covers 100 are also tightly fixed at the top, effectively preventing the top of the cover 100 from opening or deforming due to vibration or external force, thus enhancing the overall structural stability. The tight connection at the top, combined with the connection on the sides, forms a more sealed and airtight protective space, which can better prevent dust, water droplets, etc. from entering from the top seam, and also improves the level of safety protection.

[0030] Reference Figures 2 to 5 In some embodiments, the upper cover 120 has multiple through holes 130. Belt drives generate heat during operation; the through holes 130 form natural ventilation channels, facilitating heat dissipation and preventing heat accumulation inside the cover that could lead to belt overheating, aging, or decreased transmission efficiency. This is particularly suitable for heavy-duty applications requiring continuous operation, such as slurry pumps. Operators and maintenance personnel can directly observe the belt's operation, whether it is slipping, or if there is abnormal wear through the through holes 130, without opening the cover 100, enabling non-stop inspection and facilitating equipment management.

[0031] Reference Figure 4 In some embodiments, a fixing plate 140 is fixedly connected to the bottom end of the support 110, and the fixing plate 140 has multiple fixing holes 150. The fixing plate 140 provides a wide and flat mounting surface, and the support 110 can be easily and firmly fixed to the concrete foundation or equipment base by engaging with anchor bolts through the multiple fixing holes 150. The increased contact area and multiple fixing points enable the belt cover to better resist the vibration generated during equipment operation, prevent loosening, and ensure long-term operational reliability.

[0032] Example 2: This utility model discloses a split-type belt cover. (Refer to...) Figures 6 to 8The main difference from Embodiment 1 is that the connecting mechanism 200 also includes a first buffer pad 240, which is fixedly disposed between the two upper covers 120. The first buffer pad 240, for example a rubber pad, can effectively absorb and isolate the vibrations and impacts generated when the two metal covers 100 are closed and during equipment operation, significantly reducing operating noise and improving the working environment. The first buffer pad 240 fills the gaps at the joint of the covers 100, providing a good seal, while avoiding direct metal-to-metal contact friction, protecting the surface of the covers 100, and extending their service life.

[0033] Reference Figure 7 In some embodiments, the connecting mechanism 200 further includes a second buffer pad 250, which is fixedly installed at the bottom end of the support 110. The second buffer pad 250, installed between the support 110 and the equipment base, forms a second line of vibration damping. It effectively isolates vibrations generated by the slurry pump and transmission system from being transmitted to the equipment base through the belt cover, helping to protect the foundation and reduce the impact on surrounding equipment. The second buffer pad 250 can compensate for minor unevenness of the foundation mounting surface, ensuring uniform stress on the support 110 and enhancing installation stability.

[0034] Reference Figure 8 In some embodiments, the connecting mechanism 200 further includes an adjusting plate 260. One end of the adjusting plate 260 is fixedly connected to the upper cover 120, and the other end is slidably connected to the support 110. The adjusting plate 260 has multiple mounting holes 270, and the support 110 has correspondingly multiple adjusting holes 280. During installation, if there are deviations due to the position of the pulley or the embedded parts in the foundation, alignment can be achieved through different combinations of the mounting holes 270 on the adjusting plate 260 and the adjusting holes 280 on the support 110, ensuring that the two half-covers 100 can be accurately aligned and closed. This enhances adaptability to different installation conditions, improving the product's versatility and installation success rate.

[0035] Reference Figure 6 In some embodiments, the connecting mechanism 200 further includes an insert plate 291, which is fixedly mounted on the connecting plate 210. A slot 292 is provided on the connecting plate 210 opposite to the insert plate 291, and the insert plate 291 resides within the slot 292. When the two half-covers 100 are closed, the cooperation between the insert plate 291 and the slot 292 serves as a guide and initial positioning mechanism. The operator can easily slide the insert plate 291 into the slot 292, quickly aligning the two covers 100 to the correct position, greatly facilitating subsequent bolt tightening and improving installation efficiency. The insert plate 291 itself also constitutes a shear-resistant structure, working together with the connecting piece and bolts to enhance the mechanical strength of the connection, making the overall structure more reliable.

[0036] The implementation principle of a split belt cover according to an embodiment of this utility model is as follows: By redesigning the traditional one-piece cover 100 into two side-closing covers 100, the problem of installing and removing belt covers caused by the large pulleys and insufficient vertical installation space in large ZV drives is solved. Multiple connection mechanisms 200 on the top and sides ensure the overall rigidity and sealing of the cover 100. Meanwhile, the through holes 130 in the cover 100 serve both heat dissipation and observation functions, facilitating real-time monitoring of the equipment's operating status. Furthermore, the buffer pads added at the joints of the cover 100 and the bottom of the support 110 effectively isolate and absorb vibrations and noise generated during equipment operation, improving the working environment.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
