[0025] It should be understood that the embodiments of the present utility model shown in the exemplary embodiments are merely illustrative. Although only a few embodiments of the present utility model are described in detail, those skilled in the art can easily understand that various modifications are feasible without substantially departing from the teachings of the subject matter of the present utility model. Accordingly, all such modifications should be included within the scope of the present utility model. Without departing from the gist of the present utility model, other substitutions, modifications, changes, and deletions can be made to the design, operating conditions, parameters, etc. of the following exemplary embodiments.

[0026] The present utility model provides a detachable belt conveyor protection device. Please refer to Figure 1 and Figure 2 , which includes: a protective net 4, the protective net 4 includes a wire mesh 1, a plurality of angle steels 2, at least one seamless steel pipe 3, the plurality of angle steels 2 are assembled into a rectangle, the wire mesh 1 is welded inside the rectangle, the seamless steel pipe 3 is welded on the angle steels 2 along the horizontal direction of the wire mesh 1 and extends beyond two opposite sides of the angle steels 2; and a plurality of connecting pieces 7, each connecting piece 7 includes a column 5 and at least one slot 6, the slot 6 is welded to the column 5; wherein, the protective net 4 is fixed in the connecting piece 7 through the seamless steel pipe 3, and the height of the slot 6 is the same as the height of the seamless steel pipe 3.

[0027] The protective net 4 of the present utility model is detachably connected to the connecting member 7. The protective device is light and detachable, with a simple structure, safe and reliable, and convenient to maintain. It realizes the long-term use of the protective net of the belt conveyor, can be conveniently disassembled during the inspection and maintenance process, prevents damage to the belt protective net, and the outer frame of the protective net 4 made of angle steel can ensure that the protective net 4 will not deform and increase the service life.

[0028] By adopting the device of the present utility model, the safety performance of the belt conveyor can be significantly improved, and the danger during the security inspection process can be reduced. At the same time, the device also has the advantages of simple structure, convenient installation and disassembly, strong adaptability, etc., and can be widely applied to the security inspection work of various belt conveyors.

[0029] In Figure 1 In the illustrated embodiment, the number of angle steels 2 is four, and the four angle steels 2 are spliced into a rectangle; the number of seamless steel pipes 3 is four, and the four seamless steel pipes 3 are each welded to the angle steel 2 along the horizontal direction of the wire mesh 1 and extend beyond two opposite sides of the angle steel 2, that is, extend beyond the two short sides of the rectangle. It should be understood that Figure 1 For illustrative purposes only, and the number of angle steels and seamless steel pipes is not limited to this.

[0030] In some embodiments, please refer to Figure 1 and Figure 2 , the slot 6 is an L-shaped including a first side and a second side perpendicular to each other. One end of the first side is welded to the column 5, and the second side is parallel to the column 5 and spaced apart by a distance, and the distance is slightly larger than the outer diameter of the seamless steel pipe 3.

[0031] When the second side of the slot 6 is parallel to the column 5, their connection is more stable, which can ensure that when the slot 6 is subjected to an external force, the force distribution is more uniform, reducing the risk of damage caused by stress concentration. This stability is particularly important during long-term use or under heavy pressure, as it helps to maintain the integrity and reliability of the entire structure.

[0032] The generous space in slot 6 allows seamless steel pipe 3 to be inserted or removed easily and quickly without excessive precise alignment or additional tool assistance. In the case of protecting belt conveyors where components need to be frequently replaced or adjusted, it can significantly save time and improve work efficiency. During the insertion of seamless steel pipe 3, due to the extra space, it will not suffer excessive friction or extrusion due to slight misalignment or improper angle, thus reducing component wear. In the long term, it helps to maintain the integrity of the components and extend their service life. The design of slot 6 can tolerate a certain degree of manufacturing error or slight deformation of components, thus improving the adaptability and fault tolerance of the system. This is particularly important during mass production and assembly processes because components from different batches or different suppliers may have slight dimensional differences.

[0033] When seamless steel pipe 3 is inserted into slot 6, if slot 6 is too tight, stress concentration may occur, leading to component deformation or damage. The slightly generous design of slot 6 can reduce this stress, ensure uniform stress on the components during installation, and reduce the risk of damage. In an environment with large temperature variations, components may undergo dimensional changes due to thermal expansion and contraction. The design of slot 6 can accommodate this change and prevent jamming or damage caused by component deformation.

[0034] In some embodiments, refer to Figure 1 and Figure 2 , the length of slot 6 along the horizontal direction of wire mesh 1 is greater than the length by which seamless steel pipe 3 extends beyond angle steel 2, so that two adjacent protective nets 4 share the same connector 7.

[0035] The sharing of a single connector 7 by protective nets 4 can reduce the number of connectors 7, which reduces the manufacturing and installation costs for scenarios such as belt conveyors that require the application of protective nets. The shared connector 7 design simplifies the installation steps and reduces the workload during installation. Installers only need to fix connector 7 in one position and then connect adjacent protective nets to this connector 7, which greatly improves the installation efficiency. Connector 7 can support multiple protective nets 4, making the entire protective system more stable. The spacing between adjacent protective nets 4 can be effectively controlled, avoiding space waste. This is particularly important when arranging multiple protective nets in the limited space of a belt conveyor, as it can maximize the use of space resources.

[0036] The design of connector 7 enables maintenance personnel to more easily inspect and repair the protective nets. Since the number of connectors 7 is reduced, the maintenance workload is also correspondingly reduced, improving the maintenance efficiency. At the same time, the unified connector 7 design also facilitates unified management and replacement.

[0037] In some embodiments, refer to Figure 1 andFigure 2 On the outer sides of the opposite sides of the rectangle, two of the seamless steel pipes 3 are provided respectively, and the seamless steel pipes 3 on the same side are arranged parallel to each other vertically.

[0038] The main function of the seamless steel pipe 3 is to connect and fix the protective net 4 to the column 5. Through the precise correspondence with the slot 6, the seamless steel pipe 3 ensures the stability and safety of the protective net. This design enables the protective net to closely fit on the pillar, making it not easy to shift or fall off, thereby providing a stronger protective function. The seamless steel pipe 3 also has a certain supporting effect. It can help disperse the external forces borne by the protective net, such as impact forces, thereby enhancing the stability of the entire protective system. The structure of the seamless steel pipe 3 is carefully designed to be able to withstand a certain amount of pressure and impact to ensure the normal operation of the protective net. In addition, the seamless steel pipe 3 also takes into account the convenience and flexibility of installation. The corresponding design with the slot 6 enables the installer to quickly and accurately insert the seamless steel pipe 3 into the slot 6 to complete the installation of the protective net. At the same time, parameters such as the length and diameter of the seamless steel pipe 3 can be adjusted according to actual needs to adapt to different scenarios and protection requirements.

[0039] In some embodiments, please refer to Figure 1 and Figure 2 , the length of the protective net 4 is smaller than the center distance between the two support roller brackets of the belt conveyor.

[0040] When the length of the protective net 4 is slightly smaller than the center distance of the support roller brackets, a certain tension force will be generated on the net surface when it is subjected to external forces, thereby enhancing the stability of the entire protective structure. This tension state can effectively resist external factors such as wind force and impact force, reduce the risk of the protective net 4 becoming loose, deformed or damaged, and improve the overall safety. During the installation process, due to the slightly smaller length of the protective net 4, the installer can more easily adjust the position and tension of the net surface to ensure its precise alignment with the bracket. This helps to reduce installation errors, improve the installation quality, and ensure that the protective net can achieve the best effect.

[0041] When the protective net 4 needs to be maintained or replaced, due to its slightly smaller length, the operation space is relatively spacious, enabling the maintenance personnel to more conveniently carry out inspection and repair work. This makes the protective net 4 have higher adaptability in dealing with different scenarios and requirements. When it is necessary to adjust the protection range, it can be achieved by adjusting the distance between the support brackets without replacing the protective net of different lengths.

[0042] In some embodiments, the column 5 is welded to the frame of the belt conveyor.

[0043] By directly welding the upright column 5 to the machine frame, a more stable overall structure can be formed. This connection method eliminates possible looseness or displacement problems in the middle, making the entire protection system more stable and reliable. When bearing external forces, the welded upright column 5 can better maintain its position and function, reducing the risk of damage caused by vibration or impact.

[0044] Welding connection is faster and more efficient compared to other connection methods such as bolt connection. Once the welding is completed, a permanent fixed connection is formed between the upright column 5 and the machine frame, without the need for additional fasteners or tools. This not only simplifies the installation process but also reduces the installation cost and time cost.

[0045] In some embodiments, multiple upright columns can be arranged at a certain distance along the conveying direction of the belt conveyor. In one embodiment, the center distance between two of the upright columns 5 is the same as the center distance between two support roller brackets of the belt conveyor.

[0046] When the center distance between the upright columns 5 matches the center distance between two support roller brackets, the entire protection structure can evenly distribute the force, reducing the stress concentration phenomenon caused by uneven force. This uniform force distribution helps to enhance the stability of the entire structure and improve the ability to resist external impact and vibration. It can make the most of the width space of the machine frame. This design avoids space waste, enabling the protection structure to closely fit the machine frame and providing comprehensive protection for the working area. During production, it is easier to determine the position of the upright column 5 to ensure that it is aligned with the edge of the machine frame. This simplifies the installation process, improves the installation efficiency, and reduces the risk of installation errors caused by inaccurate positioning.

[0047] In some embodiments, please refer to Figure 1 and Figure 2 , the length of the rectangle is slightly less than the center distance between two support roller brackets of the belt conveyor.

[0048] The length of the rectangle being slightly less than the center distance between two support roller brackets means that it is easier to adapt to machine brackets of different sizes or models, increasing the installation flexibility, enabling the same protection net to be adapted to multiple machine types, and reducing inventory and costs.

[0049] Due to the smaller size and strong adaptability of the protection net, it can be more easily installed on the machine bracket. Similarly, when disassembly or replacement is required, this design can also reduce the operation complexity and time cost.

[0050] In some embodiments, please refer to Figure 1 and Figure 2 , both of the upright columns 5 are welded with two of the slots 6, and the slots 6 are arranged parallel to each other vertically.

[0051] Through the unified design of the slot 6, compatibility can be ensured, which means that when replacing or repairing components, operations can be carried out more conveniently, improving work efficiency. The slots 6 are arranged parallel to each other vertically, which can ensure better stability when the protective net 4 is connected. This stability not only helps to resist external impacts but also reduces the risk of component loosening or displacement. The slot 6 makes the installation process simpler and more intuitive. Installers only need to align the components with the slot 6 and fix them to complete the installation, without complex operations or tools. As requirements change, it may be necessary to add or reduce the protective net or other components on the strut. Multiple vertically parallel slots 6 facilitate future expansion and upgrade, making the entire protection system easier to adjust and optimize.

[0052] In some embodiments, refer to Figure 1 and Figure 2 , both the column 5 and the slot 6 are channel steels, and the size of the channel steel of the column 5 is larger than that of the channel steel of the slot 6.

[0053] The sizes of the column 5 and the slot 6 can be different. Channel steel has high strength and excellent toughness and can withstand large pressure and tensile forces. Therefore, when both the column 5 and the slot 6 are made of channel steel, the entire structure will be very stable, not easily deformed or damaged, and can resist various external forces, such as wind force and impact force. It can reduce material costs. At the same time, due to the high strength and long service life of channel steel, it can also reduce the later maintenance cost. Channel steel is easy to process and can be subjected to processes such as cutting, drilling, and welding as needed. This means that whether manufacturing the column 5 or the slot 6, it can be completed conveniently and quickly, improving work efficiency.

[0054] In this application, the sizes of the channel steels are different. The channel steel of the column 5 has a larger size, and the slot 6 uses a channel steel with a smaller size, which not only saves costs but also is relatively light in installation and easy to disassemble.

[0055] In some embodiments, refer to Figure 1 and Figure 2 , the slot 6 is formed by welding the vertical side of the channel steel to the hollow part of the column 5.

[0056] The hollow part of the channel steel is used as a slot, which not only saves materials but also makes full use of the cross-sectional shape of the channel steel. This design makes the whole structure more compact, reduces unnecessary weight and volume, and conforms to the trend of lightweight design. Since the slot 6 is the hollow part of the channel steel, the parts to be connected can be directly inserted into it without additional fixing or fastening parts. This design simplifies the installation and disassembly process and improves work efficiency. At the same time, the opening design of the slot 6 also facilitates observing and inspecting the connection situation to ensure the connection quality. The cross-sectional shape and size of the channel steel can be customized according to needs, so the size and shape of the slot 6 can also be flexibly adjusted. This enables the design to adapt to columns and connection parts of different specifications and requirements, providing a wider application range.

[0057] The present application will be further described below through specific embodiments.

[0058] As Figure 1 and Figure 2 shown, a detachable belt conveyor protection device includes a wire mesh 1, an angle steel 2, a seamless steel pipe 3, a protection net 4 made by welding the wire mesh 1, the angle steel 2 and the seamless steel pipe 3, a column 5, and a slot 6. The column 5 and the slot 6 are channel steels. The slot 6 is welded to the column 5, and the column 5 is welded to the belt conveyor frame. The protection net 4 is installed in the slot 6 on the column 5.

[0059] Each protection net 4 of the present utility model is welded with four seamless steel pipes 3.

[0060] Each column 5 of the present utility model is welded with 2 slots 6.

[0061] The center distance between two columns 5 of the present utility model is the same as the center distance between two support roller brackets of the belt conveyor. The length of the protection net 4 is slightly smaller than the center distance between two support roller brackets of the belt conveyor to ensure that it can be installed in the slot on the column.

[0062] Two adjacent protection nets 4 of the present utility model share the same column 5 and slot 6.

[0063] The utility model uses a steel wire mesh 1, angle steel 2, and seamless steel pipes 3 to be welded and fabricated into a protective net 4. The angle steel 2 is used to fabricate a rectangle as the frame of the protective net 4, the steel wire mesh 1 is welded inside the frame of the protective net 4, and four seamless steel pipes 3 are welded to the outer frame of the protective net 4. Two types of channel steels with different sizes are used to weld and fabricate the columns 5 and the slots 6. The width of the channel steel used for the slot 6 is slightly larger than the outer diameter of the seamless steel pipe 3 on the protective net 4. The slot 6 is welded to the column 5. The heights of the two slots 6 are the same as the heights of the seamless steel pipes 3 fixed on both sides of the protective net 4. The column 5 is welded to the belt conveyor frame, and the protective net 4 is installed in the slot 6 on the column 5. Two adjacent protective nets 4 share the same column 5 and slot 6. The center distance between the two columns 5 is the same as the center distance between the two support roller brackets of the belt conveyor. The length of the protective net 4 is slightly smaller than the center distance between the two support roller brackets of the belt conveyor, ensuring that it can be installed in the slot 6 on the column 5. The height of the protective net 4 can be adjusted according to specific circumstances. Since the spacing between the support roller brackets of the belt conveyor is the same, the protective nets and columns can be mass-produced in advance and installed uniformly.
