[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] The present application will be further described in detail below with reference to the accompanying drawings.
[0021] Belt conveyors, also known as rubber belt conveyors or belt conveyors, are general-purpose mechanical equipment that uses a conveyor belt as the traction and load-bearing mechanism. Driven by the friction between the conveyor belt and the drive roller, they achieve continuous and efficient material transport. They are widely used in mining, metallurgy, chemical, port, and building materials industries, and their operational stability directly determines the efficiency and safety of material transport. Idler roller assemblies, as a key core component of belt conveyors, primarily support the conveyor belt and the total weight of the transported materials. Simultaneously, through their rotational characteristics, they convert the sliding friction between the conveyor belt and the idler rollers into rolling friction, significantly reducing frictional resistance, minimizing conveyor belt wear, extending the conveyor belt's service life, and ensuring continuous and stable operation of the conveyor. Idler roller assemblies can be functionally categorized into trough idler roller assemblies, various parallel idler roller assemblies, various impact idler roller assemblies, various self-aligning idler roller assemblies, and various self-aligning idler roller assemblies, each adaptable to different conveying sections (carrying section, return section), different inclination angles, and different material transport requirements. The idler roller bracket is a supporting component in the idler roller assembly, directly supporting the installation and fixing of the idler rollers. Its main function is to provide precise support and secure fixation for the idler rollers, ensuring they maintain their preset installation posture. This, in turn, guarantees smooth and centered operation of the conveyor belt, preventing abnormal situations such as deviation and vibration. Simultaneously, it bears the combined load of the conveyor belt and materials, resists material impact, and ensures the long-term stable operation of the conveyor. Figures 1-11 As shown, depending on the role of the idler bracket in the conveyor, the suitable conveying conditions, and the different structural forms, they can be divided into trough-shaped forward-inclined idler brackets, parallel upper idler brackets, V-shaped lower idler brackets, conical upper self-aligning idler brackets with vertical rollers, conical lower self-aligning idler brackets with vertical rollers, trough-shaped buffer idler brackets, and double-roller parallel buffer idler brackets.
[0022] This application discloses a roller support for a belt conveyor, comprising a tubular connecting beam, a first reinforcing rib and a second reinforcing rib, and a support assembly; the tubular connecting beam has a first end and a second end disposed opposite to each other; the first reinforcing rib is connected to the first end; the second reinforcing rib is connected to the second end; the support assembly is connected to the tubular connecting beam; the support assembly is provided with a roller mounting part for assembling rollers.
[0023] The tubular connecting beam is the basic load-bearing component of the entire idler support. It has a first end and a second end that are arranged opposite each other. Its structural selection and size design are determined according to the load-bearing requirements of the support, ensuring that it has sufficient strength and rigidity to avoid deformation under stress. The first reinforcing rib is fixedly connected to the first end of the tubular connecting beam, and the second reinforcing rib is fixedly connected to the second end of the tubular connecting beam to enhance the structural strength of the ends of the tubular connecting beam, distribute the stress at the ends, and prevent the ends of the tubular connecting beam from breaking or deforming due to local stress concentration. The support assembly is fixedly connected to the tubular connecting beam and is the direct mounting carrier for the idler. It is equipped with an idler mounting part, which is specially used for assembling the idler. The idler mounting part realizes the precise positioning and firm fixation of the idler, ensuring that the idler does not shift or shake during operation.
[0024] Example 1 in this application: like Figure 1 and Figure 4 As shown, in this embodiment, the idler bracket for the belt conveyor is a parallel upper idler bracket 2, used for the carrying section of the belt conveyor. It is suitable for belt conveyors with an inclination angle of 0°, i.e., the conveyor belt is completely horizontal without any upward or downward tilt, and is mainly used for horizontal material conveying. The idler mounting part includes a first groove and a second groove; the support assembly includes a first side support 1-1-1 and a second side support 1-1-3; one end of the first side support 1-1-1 is connected to the first reinforcing rib 1-1-6, and the other end is provided with a first groove; one end of the second side support 1-1-3 is connected to the second reinforcing rib 1-1-8, and the other end is provided with a second groove; the first groove and the second groove are used for assembling the idler. The support assembly further includes a first bracket 2-1-1 and a second bracket 2-1-2; the first bracket 2-1-1 is embedded between the first side support 1-1-1 and the first reinforcing rib 1-1-6, and is connected to the first side support 1-1-1 and the first reinforcing rib 1-1-6; the second bracket 2-1-2 is embedded between the second side support 1-1-3 and the second reinforcing rib 1-1-8, and is connected to the second side support 1-1-3 and the second reinforcing rib 1-1-8.
[0025] In use, the tubular connecting beam 1-1-5 is made of steel pipe; the first reinforcing rib 1-1-6 and the second reinforcing rib 1-1-8 are both made of stiffening plates, and their cross-sectional shape is triangular, so as to effectively distribute the force at the end of the tubular connecting beam 1-1-5, enhance the structural strength of the end, and prevent the end from deforming; the cross-sectional shape of the first support 2-1-1 and the second support 2-1-2 is "L" shaped, so the first support 2-1-1 and the second support 2-1-2 each include a long side and a short side. The "L" shaped structure can adapt to the connection angle between the side support and the reinforcing rib and the tubular connecting beam 1-1-5, increase the connection contact area, and improve the connection firmness. In actual production, the first support 2-1-1 and the first reinforcing rib 1-1-6 are sequentially welded to the first end of the tubular connecting beam 1-1-5. The first side support 1-1-1 is welded to the side of the first support 2-1-1 away from the first reinforcing rib 1-1-6, and the end of the first side support 1-1-1 is welded to the first end of the tubular connecting beam 1-1-5. Similarly, the second support 2-1-2 and the second reinforcing rib 1-1-8 are sequentially welded to the second end of the tubular connecting beam 1-1-5. The second side support 1-1-3 is welded to the side of the second support 2-1-2 away from the second reinforcing rib 1-1-8, and the end of the second side support 1-1-3 is welded to the second end of the tubular connecting beam 1-1-5. In this way, the first reinforcing rib 1-1-6 and the first support 2-1-1 enhance the overall strength and load-bearing capacity of the idler roller support, improving operational stability.
[0026] In this embodiment, the first side support 1-1-1 has a first groove at its end opposite to the tubular connecting beam 1-1-5, and the second side support 1-1-3 has a second groove at its end opposite to the tubular connecting beam 1-1-5. The idler roller is positioned and fixed by engaging its shaft ends in the first and second grooves, allowing it to rotate freely around its own shaft ends. The conveyor belt is laid on the idler roller, and the idler roller rotates synchronously under the frictional force of the conveyor belt, converting the sliding friction between the conveyor belt and the idler roller into rolling friction, significantly reducing frictional resistance and conveyor belt wear. The first reinforcing rib 1-1-6 and the first support 2-1-1, the second reinforcing rib 1-1-8 and the second support 2-1-2 form a double reinforcing structure, effectively enhancing the overall strength and load-bearing capacity of the idler roller support, enabling it to stably withstand the combined load of the conveyor belt and materials, and preventing deformation and breakage of the support. The symmetrical side support structure ensures that the idler roller is installed horizontally, ensuring smooth operation of the conveyor belt and preventing abnormal situations such as deviation and shaking, thereby improving the operational stability and conveying efficiency of the belt conveyor. The crossbeams of ordinary trough roller supports are made of angle steel, while in this embodiment, the tubular connecting beams are made of steel pipe, which has the characteristics of high strength, high rigidity and high load-bearing capacity.
[0027] In one embodiment, the short sides of the first bracket 2-1-1 and the second bracket 2-1-2 are provided with screw holes. By passing a bolt through the screw holes, the roller bracket can be fixed as a whole in the predetermined position of the conveyor frame. The bolt connection has the advantages of easy disassembly and firm fixation, which facilitates the installation, maintenance and replacement of the bracket, while ensuring that the bracket does not shift during operation.
[0028] Example 2 in this application: like Figure 2 and Figure 3 As shown, in one embodiment, the idler bracket for the belt conveyor is a trough-shaped forward-inclined idler bracket 1, used for the carrying section of the belt conveyor, and is suitable for belt conveyors with an inclination angle of 0-20°, that is, the arrangement inclination angle of the belt conveyor is between 0° and 20°, covering horizontal conveying and upward inclined conveying conditions.
[0029] Specifically, the first side support 1-1-1 includes a first fixing part, a first connecting part, and a first inclined part connected in sequence; the second side support 1-1-3 includes a second fixing part, a second connecting part, and a second inclined part connected in sequence; wherein, the first inclined part is provided with a first groove; the second inclined part is provided with a second groove; the first groove and the second groove are used for assembling the idler roller. The support assembly also includes at least one first middle support 1-1-2, a first connecting plate 1-1-4, and a second connecting plate 1-1-7; at least one first middle support 1-1-2 is connected to the middle part of the tubular connecting beam 1-1-5; one end of the first connecting plate 1-1-4 is connected to the tubular connecting beam 1-1-5, and the other end is connected to the first side support 1-1-1; one end of the second connecting plate 1-1-7 is connected to the tubular connecting beam 1-1-5, and the other end is connected to the second side support 1-1-3; wherein, the cross-sectional shape of the first middle support 1-1-2 is a right-angled triangle.
[0030] In use, two first central supports 1-1-2 are provided, which are welded at intervals to the middle of the tubular connecting beam 1-1-5. A right angle is formed between the first fixing part and the first connecting part, and the cross-sectional shape of the first reinforcing rib 1-1-6 is a right triangle. Therefore, the first reinforcing rib 1-1-6 can be embedded and welded between the first fixing part and the first connecting part. Similarly, a right angle is formed between the second fixing part and the second connecting part, and the cross-sectional shape of the second reinforcing rib 1-1-8 is a right triangle. Therefore, the first reinforcing rib 1-1-6 can be embedded and welded between the second fixing part and the second connecting part. At the same time, the side of the first connecting part away from the first fixing part is welded to the first end of the tubular connecting beam 1-1-5, and the side of the second connecting part away from the second fixing part is welded to the second end of the tubular connecting beam 1-1-5. In this way, the load transmitted by the side supports is distributed, preventing the side supports from tilting or deforming, and further enhancing the overall stability of the support. In this embodiment, the first fixing part and the second fixing part are provided with screw holes, and a bolt is passed through the screw holes to fix the roller bracket as a whole to the predetermined position of the conveyor frame.
[0031] In this embodiment, both the first connecting plate 1-1-4 and the second connecting plate 1-1-7 are made of steel plates. One end of the first connecting plate 1-1-4 is welded to the end of the first connecting part near the first inclined part, and the other end is welded to the tubular connecting beam 1-1-5. One end of the second connecting plate 1-1-7 is welded to the end of the second connecting part near the second inclined part, and the other end is welded to the tubular connecting beam 1-1-5. The first connecting plate 1-1-4 and the second connecting plate 1-1-7 further enhance the overall stability of the idler support. The crossbeam of a common trough idler support is made of angle steel. In this embodiment, because the tubular connecting beam is made of steel pipe, it has the characteristics of high strength, high rigidity, and high load-bearing capacity.
[0032] In one embodiment, the angle between the first connecting plate 1-1-4 and the tubular connecting beam 1-1-5 is 10 to 35 degrees; and / or, the angle between the second connecting plate 1-1-7 and the tubular connecting beam 1-1-5 is 10 to 35 degrees. Specifically, in the trough-shaped forward-inclined idler bracket 1, the included angle between the first connecting plate 1-1-4 and the second connecting plate 1-1-7 and the tubular connecting beam 1-1-5 is 35°; the first inclined part is inclined toward the side of the second side support 1-1-3, and the included angle between the first inclined part and the first connecting part is 145°; the second inclined part is inclined toward the side of the first side support 1-1-1, and the included angle between the second inclined part and the first connecting part is 145°. This inclination angle design allows the assembled idler to form a trough-shaped structure that meets the material conveying requirements, which is convenient for carrying materials and ensures good fit between the conveyor belt and the idler, reducing conveyor belt wear. At the same time, since the first and second inclined parts are symmetrically inclined, the assembled idler can form a trough-shaped structure, which can effectively carry materials and prevent materials from rolling off during inclined conveying.
[0033] The first inclined portion has a first groove, and the second inclined portion has a second groove for assembling idler rollers. In actual use, the distance between the centerline of the first groove and the centerline of the first inclined portion is 14-15 mm; the distance between the centerline of the second groove and the centerline of the second inclined portion is also 14-15 mm. Specifically, the first groove is located 14 mm off the centerline of the first inclined portion, and the second groove is located 14 mm off the centerline of the second inclined portion. After the idler rollers are assembled, the idler rollers can form the target groove shape, and at the same time, the idler rollers are in a slightly forward tilted state. The friction between the conveyor belt and the idler rollers generates a correction torque. When the conveyor belt tends to deviate, the correction torque can push the conveyor belt back to the center position, realizing the automatic correction function, effectively preventing the conveyor belt from deviating, and ensuring the stable operation of the conveyor. In this embodiment, the first side support 1-1-1, the second side support 1-1-3, and the first middle support 1-1-2 are all formed by stamping steel plates. Stamping steel plates have the characteristics of high processing efficiency, high structural precision, high strength, high rigidity, and strong load-bearing capacity, which can meet the load requirements under inclined conveying conditions and extend the service life of the support.
[0034] Example 3 in this application: like Figure 5 and Figure 6As shown, in one embodiment, the idler bracket for the belt conveyor is a V-shaped lower idler bracket 3, used for the return section of the belt conveyor. It is suitable for belt conveyors with an inclination angle of 0-20°. Its core function is to support the conveyor belt in the return section, prevent the conveyor belt from running off-track, reduce the frictional resistance between the conveyor belt and the idler, protect the conveyor belt, and ensure the continuous and stable operation of the conveyor. Specifically, the support assembly includes at least one second middle support 3-1-2, which is connected to the middle part of the tubular connecting beam 1-1-5; the cross-sectional shape of at least one second middle support 3-1-2 is an isosceles triangle; the first reinforcing rib 1-1-6 includes a first hanger 3-1-1 and a first stiffening plate; the second reinforcing rib 1-1-8 includes a second hanger 3-1-3 and a second stiffening plate 3-1-5; wherein, one end of the first hanger 3-1-1 is connected to the first end, and the other end is provided with a first clamping plate; the first stiffening plate is disposed on the first hanger 3-1-1 and located below the first clamping plate, and is connected to the first clamping plate; one end of the second hanger 3-1-3 is connected to the second end, and the other end is provided with a second clamping plate 3-1-4; the second stiffening plate 3-1-5 is disposed on the second hanger 3-1-3 and located below the second clamping plate 3-1-4, and is connected to the second clamping plate 3-1-4. In one embodiment, the first hanger 3-1-1 and the second hanger 3-1-3 are provided with screw holes, and a bolt is passed through the screw holes to fix the roller bracket as a whole in a predetermined position on the conveyor frame.
[0035] Specifically, the first hanger 3-1-1 and the second hanger 3-1-3 are welded to the first end and the second end of the tubular connecting beam 1-1-5, respectively. At the same time, a first clamping plate is welded to the side of the first hanger 3-1-1 near the second hanger 3-1-3, and a second clamping plate 3-1-4 is welded to the side of the second hanger 3-1-3 near the first hanger 3-1-1. The first clamping plate and the second clamping plate 3-1-4 are used to assemble the idler roller. One end of the first card plate is welded to the first hanger 3-1-1, and the other end is inclined toward the tubular connecting beam 1-1-5, with the first card plate tilting downward at an angle of 10°; one end of the second card plate 3-1-4 is welded to the second hanger 3-1-3, and the other end is inclined toward the tubular connecting beam 1-1-5, with the second card plate 3-1-4 tilting downward at an angle of 10°. This design ensures that after the idlers are assembled, the idlers are arranged in a V-shape. The V-shaped structure can center and limit the conveyor belt in the return section, preventing the conveyor belt from running off-center. At the same time, it ensures that the spacing and arrangement of the idlers meet the operating requirements of the conveyor belt, so that the conveyor belt and the idlers fit perfectly together and reduce frictional resistance.
[0036] In this embodiment, the first stiffening plate is welded to the first hanger 3-1-1 and located below the first clamping plate. The second stiffening plate 3-1-5 is welded to the second hanger and located below the second clamping plate 3-1-4. Thus, the first and second stiffening plates 3-1-5 provide support to the first and second clamping plates 3-1-4, ensuring their support strength and preventing deformation of the clamping plates due to the weight of the idler rollers after assembly. Simultaneously, the stiffening plates also enhance the load-bearing capacity of the first and second clamping plates 3-1-4, thereby improving the overall rigidity and stability of the idler roller bracket and extending its service life. In this embodiment, because the tubular connecting beam uses steel pipe material, it features high strength, high rigidity, and high load-bearing capacity.
[0037] Example 4 in this application: like Figure 7 and Figure 8 As shown, in one embodiment, the idler bracket for the belt conveyor is a tapered self-aligning idler bracket 4 with vertical rollers, used in the carrying section of the belt conveyor, and suitable for belt conveyors with an inclination angle of 0-20°. Specifically, the support assembly includes a third central support 6-1-1, a third side support 4-1-2, and a fourth side support 4-1-5, as well as a third connecting plate 4-1-1 and a fourth connecting plate 4-1-4; the third central support 6-1-1 is rotatably disposed in the middle of the tubular connecting beam 1-1-5; the third side support 4-1-2 and the fourth side support 4-1-5 are disposed opposite to each other on both sides of the third central support 6-1-1; the third connecting plate 4-1-1 is connected at one end to the third side support 4-1-2 and at the other end to the third central support 6-1-1; the fourth connecting plate 4-1-4 is connected at one end to the fourth side support 4-1-5 and at the other end to the third central support 6-1-1.
[0038] Specifically, one end of the third central support 6-1-1 is welded to the third connecting plate 4-1-1, and the other end is welded to the fourth connecting plate 4-1-4. A third side support 4-1-2 is welded to the end of the third connecting plate 4-1-1 opposite to the third central support, and a fourth side support 4-1-5 is welded to the end of the fourth connecting plate 4-1-4 opposite to the end of the third central support 6-1-1. These welded connections form an integrated structure, ensuring a firm connection between all components and enabling stable load bearing of the idlers and materials. This structure allows for the support and positioning of three conical idlers and two vertical rollers. After assembly, the idler cross-section forms the target groove shape, facilitating material loading and enabling self-aligning through the conical idler structure. The vertical rollers further serve as limiters, preventing conveyor belt deviation. In this embodiment, both the third connecting plate 4-1-1 and the fourth connecting plate 4-1-4 are angle steel. Angle steel is characterized by its simple structure, high strength, and good weldability, effectively transferring loads and enhancing the strength of the connection points.
[0039] In this embodiment, the tubular connecting beam 1-1-5 is a channel steel. Channel steel has the characteristics of large moment of inertia, strong bending resistance, and high load-bearing capacity, which can effectively bear the load of the entire support assembly, rollers, and materials, while being easy to process and install. The first reinforcing rib 1-1-6 and the second reinforcing rib 1-1-8 are both angle steels, which are welded to the first end and the second end of the tubular connecting beam 1-1-5, respectively, to effectively enhance the structural strength of the ends of the tubular connecting beam 1-1-5, distribute the stress at the ends, and prevent the ends of the tubular connecting beam 1-1-5 from deforming or breaking.
[0040] The third support column 6-1-1 is rotatably mounted in the middle of the tubular connecting beam 1-1-5 via a rotating mechanism 4-1-3. Specifically, the rotating mechanism 4-1-3 includes a central shaft assembly 4-1-3-1 and a self-aligning base 4-1-3-2; the self-aligning base 4-1-3-2 is provided with a connecting channel; the central shaft assembly 4-1-3-1 is inserted into the connecting channel, and a thrust ball bearing 4-1-3-4 and a deep groove ball bearing 4-1-3-5 are provided between the central shaft assembly 4-1-3-1 and the self-aligning base 4-1-3-2. The thrust ball bearing and the deep groove ball bearing 4-1-3-5 work together to ensure that the central shaft assembly 4-1-3-1 can rotate flexibly and smoothly, reduce rotational friction, and extend the service life of the rotating mechanism 4-1-3; at the same time, one end of the central shaft assembly 4-1-3-1 is fixedly connected to the third central support 6-1-1, and the other end is rotatably mounted on the tubular connecting beam 1-1-5; the self-aligning base 4-1-3-2 is fixed on the tubular connecting beam 1-1-5 to form a stable installation foundation.
[0041] In use, the central shaft assembly 4-1-3-1 can rotate together with the third central support 6-1-1, with a rotation angle of approximately 10°. Specifically, three conical idlers are assembled on both sides of the third central support 6-1-1 via side supports and connecting plates, forming a trough-shaped structure. The conveyor belt is laid on the conical idlers to carry and transport materials. Two vertical rollers are set on both sides of the conveyor belt to limit movement and prevent serious belt deviation. The idlers rotate synchronously under the frictional force of the conveyor belt, reducing frictional resistance and conveyor belt wear. When the conveyor belt tends to deviate, the frictional force between the conveyor belt and the conical idlers generates a lateral force, which drives the third central support 6-1-1 and the central shaft assembly 4-1-3-1 to rotate around the self-aligning base 4-1-3-2 (rotation angle of approximately 10°), adjusting the tilt angle of the idlers and generating a corrective torque to push the conveyor belt back to the center position, achieving automatic self-alignment and effectively preventing conveyor belt deviation. In this embodiment, the first and second ends of the tubular connecting beam 1-1-5 are provided with screw holes. By passing bolts through the screw holes, the roller bracket can be fixed as a whole in the predetermined position of the conveyor frame, ensuring that the bracket does not shift during operation and guaranteeing the stable realization of the self-aligning function.
[0042] Example 5 in this application: like Figure 9 As shown, in one embodiment, the idler bracket for the belt conveyor is a tapered self-aligning idler bracket 5 with vertical rollers, suitable for the return section of the belt conveyor, and suitable for belt conveyor inclination angles of 0-20°. Its core function is to support the conveyor belt in the return section, and it also has an automatic self-aligning function to correct belt deviation and ensure stable operation of the conveyor belt in the return section. Its structure is basically the same as that of the tapered self-aligning idler bracket 4 with vertical rollers, the main difference being the different conveying sections it is suited for. Similar to the tapered self-aligning idler bracket 4 with vertical rollers, one end of the third central support 6-1-1 is welded to the third connecting plate 4-1-1, and the other end is welded to the fourth connecting plate 4-1-4; the end of the third connecting plate 4-1-1 opposite to the third central support 6-1-1 is welded with a third side support 4-1-2, and the end of the fourth connecting plate 4-1-4 opposite to the end of the third central support 6-1-1 is welded with a fourth side support 4-1-5. The above structure supports and positions three tapered rollers and two vertical rollers, forming the target groove shape in the cross-section. In this embodiment, both the third connecting plate 4-1-1 and the fourth connecting plate 4-1-4 are angle steel.
[0043] In this embodiment, the tubular connecting beam 1-1-5 is a channel steel, and the first reinforcing rib 1-1-6 and the second reinforcing rib 1-1-8 are both angle steels, which are welded to the first end and the second end of the tubular connecting beam 1-1-5, respectively. The third middle support 6-1-1 is rotatably disposed in the middle of the tubular connecting beam 1-1-5 by means of a rotating mechanism 4-1-3. Specifically, the rotating mechanism 4-1-3 includes a central shaft assembly 4-1-3-1 and a self-aligning base 4-1-3-2; the self-aligning base 4-1-3-2 has a connecting channel; the central shaft assembly 4-1-3-1 is inserted into the connecting channel, and a thrust ball bearing 4-1-3-4 and a deep groove ball bearing 4-1-3-5 are provided between the central shaft assembly 4-1-3-1 and the self-aligning base 4-1-3-2; one end of the central shaft assembly 4-1-3-1 is fixedly connected to the third central support 6-1-1, and the other end is rotatably mounted on the tubular connecting beam 1-1-5; the self-aligning base 4-1-3-2 is fixed on the tubular connecting beam 1-1-5. This design allows the central shaft assembly 4-1-3-1 to rotate together with the third central support 6-1-1, with a rotation angle of approximately 10°, to correct conveyor belt deviation. It is also adaptable to various working conditions, supports long-distance conveying, and can withstand repeated impacts and vibrations.
[0044] During operation, the return section of the conveyor belt is laid on tapered idlers. Driven by the friction of the conveyor belt, the idlers rotate synchronously, reducing frictional resistance and minimizing belt wear. Two vertical rollers are positioned on either side of the conveyor belt to act as limiters, preventing severe belt misalignment. When the conveyor belt begins to deviate, the friction between the conveyor belt and the tapered idlers causes the third central support column 6-1-1 and the central shaft assembly 4-1-3-1 to rotate around the self-aligning base 4-1-3-2 (rotation angle approximately 10°). This adjusts the idler angle, generating a corrective torque that pushes the conveyor belt back to its centered position, achieving automatic self-alignment and ensuring stable operation of the return section of the conveyor belt.
[0045] In this embodiment, the first reinforcing rib 1-1-6 includes a third stiffening plate 5-1-1 and a first bent plate 5-1-2 connected to each other, and the second reinforcing rib 1-1-8 includes a fourth stiffening plate 5-1-3 and a second bent plate 5-1-4 connected to each other; the third stiffening plate 5-1-1 and the fourth stiffening plate 5-1-3 are respectively welded to the first end and the second end of the tubular connecting beam 1-1-5 to improve the overall stability. In one embodiment, the first end and the second end are provided with screw holes, and a bolt passes through the screw holes to fix the roller bracket as a whole to a predetermined position on the conveyor frame.
[0046] Example 6 in this application: like Figure 10As shown, in one embodiment, the idler bracket for the belt conveyor is a trough-shaped buffer idler bracket 6, suitable for the load-bearing section of the belt conveyor's loading area, and applicable to belt conveyors with an inclination angle of 0-20°. When material falls from the loading area, it will cause a significant impact on the conveyor belt. Therefore, the core design objective of this bracket is to buffer the material impact, protect the conveyor belt, and simultaneously stabilize the load-bearing material, ensuring a smooth and stable loading process. Specifically, the support assembly includes a fifth-side support and a sixth-side support 6-1-2, which are welded to the first and second ends of the tubular connecting beam 1-1-5, respectively. Simultaneously, the first reinforcing rib 1-1-6 and the second reinforcing rib 1-1-8 both utilize a base plate and are welded to the tubular connecting beam 1-1-5. The support assembly also includes two third intermediate supports 6-1-1, a fifth connecting plate, and a sixth connecting plate 6-1-4. The two third intermediate supports 6-1-1 are welded at intervals in the middle of the tubular connecting beam 1-1-5. The cross-sectional shape of the third intermediate supports 6-1-1 is trapezoidal. Meanwhile, one end of the fifth connecting plate is welded to the fifth side support, and the other end is welded to the tubular connecting beam 1-1-5. One end of the sixth connecting plate 6-1-4 is welded to the sixth side support 6-1-2, and the other end is welded to the tubular connecting beam 1-1-5, to improve the overall stability of the idler support. In this embodiment, the fifth side support, the sixth side support 6-1-2, and the third intermediate supports 6-1-1 are all provided with grooves to support and assemble the buffer idler. In one embodiment, the base plate is provided with screw holes, and a bolt passes through the screw holes to fix the entire idler support to a predetermined position on the conveyor frame.
[0047] During operation, the buffer idlers are assembled into the grooves of the side and center supports via their shaft ends, forming a trough-shaped structure. Material falls from the loading point onto the conveyor belt. The buffer idlers, utilizing their own elasticity and the buffer structure of the supports, absorb the impact force generated by the falling material, reducing impact damage to the conveyor belt, protecting it, and extending its service life. The trough-shaped structure effectively supports the material, preventing spillage, while ensuring good contact between the conveyor belt and the idlers. The idlers rotate synchronously under the frictional force of the conveyor belt, reducing frictional resistance and minimizing conveyor belt wear. In this embodiment, because the tubular connecting beam uses steel pipe material, it features high strength, high rigidity, and high load-bearing capacity.
[0048] Example 7 in this application: like Figure 11As shown, in one embodiment, the idler bracket for the belt conveyor is a double-roller parallel buffer idler bracket 7, suitable for the load-bearing section at the feeding point of the belt conveyor, and for belt conveyors with an inclination angle of 0°. Specifically, the support assembly includes a seventh side support 7-1-1 and an eighth side support, as well as a parallel center support 7-1-2. The seventh side support 7-1-1 and the eighth side support are respectively welded to the first and second ends of the tubular connecting beam 1-1-5, and the parallel center support 7-1-2 is welded to the middle of the tubular connecting beam 1-1-5. The seventh side support 7-1-1, the eighth side support, and the parallel center support 7-1-2 are all stamped from steel plates. Similarly, the first reinforcing rib 1-1-6 and the second reinforcing rib 1-1-8 are both made of base plates and are welded to the tubular connecting beam 1-1-5. In this embodiment, a set of double-roller parallel buffer idler brackets 7 can install two idlers in parallel to meet the requirements of wide and high-capacity belt conveyors. In one embodiment, the base plate has screw holes, through which a bolt is passed to fix the idler roller bracket to a predetermined position on the conveyor frame. In this embodiment, because the tubular connecting beam is made of steel pipe, it has the characteristics of high strength, high rigidity, and high load-bearing capacity.
[0049] like Figures 1-11 As shown, in one embodiment, to adapt to the working conditions of different conveying sections of the belt conveyor and achieve efficient and stable operation of the whole machine, the above-mentioned types of idler brackets are reasonably combined and applied. Specifically, for the loading section of the belt conveyor, based on the impact intensity of the loading, the width of the conveyor belt, and the conveying capacity requirements, trough-shaped buffer idler brackets or double-roller parallel buffer idler brackets are selected. Among them, the trough-shaped buffer idler bracket is suitable for loading conditions with an inclination angle of 0-20°, which can effectively absorb the impact of falling materials and prevent material spillage. The double-roller parallel buffer idler bracket is suitable for loading conditions with a horizontal angle of 0°, and is suitable for scenarios with large width and large conveying capacity. Both can protect the conveyor belt at the loading point and avoid impact damage.
[0050] The main load-bearing section (non-feeding section) of the belt conveyor adopts a combined design, specifically two combination methods: The first is a combination of a vertical roller conical self-aligning idler bracket and a trough-shaped forward-inclined idler bracket, suitable for 0-20° inclination load conditions. The trough-shaped forward-inclined idler bracket forms a trough-shaped load-bearing structure, which facilitates material conveying and has basic correction capabilities. The vertical roller conical self-aligning idler bracket further enhances the self-aligning function, promptly correcting belt deviation, while the vertical rollers act as limiters and protectors. The second is a combination of a vertical roller conical self-aligning idler bracket and a parallel upper idler bracket, suitable for 0° horizontal load conditions. The parallel upper idler bracket ensures the conveyor belt runs horizontally and smoothly, while the vertical roller conical self-aligning idler bracket is responsible for self-aligning and correction. The two work together to improve the operational stability of the horizontal load-bearing section.
[0051] Meanwhile, the return section of the belt conveyor (the return section of the empty conveyor belt) adopts a combination of V-shaped lower idler brackets and tapered lower self-aligning idler brackets with vertical rollers, which is suitable for return conditions with an inclination angle of 0-20°. Among them, the V-shaped lower idler brackets play a centering and limiting role for the return conveyor belt, preventing the conveyor belt from running off-track, while the tapered lower self-aligning idler brackets with vertical rollers further realize the automatic self-aligning function, correcting slight deviations in a timely manner. The two work together to ensure that the conveyor belt in the return section runs smoothly and without deviation, reducing conveyor belt wear and extending the service life of the entire machine.
