Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a triangular idler group for belt conveyors. Background Technology

[0002] Belt conveyors are widely used in industries such as mining, ports, and metallurgy. As the core component carrying the conveyor belt and materials, the idler roller assembly has a significant impact on conveying efficiency, energy consumption, and equipment lifespan. During material transport, the support stability of the idler roller assembly directly affects conveying efficiency and equipment lifespan. Traditional idler roller assemblies often use parallel or trough-shaped arrangements, which have the following problems: uneven belt stress easily leads to belt misalignment; fixed idler layout cannot adapt to different material characteristics and conveying conditions; non-adjustable idler height easily causes material spillage or excessive belt wear; and insufficient structural strength makes them prone to deformation after long-term operation. Therefore, it is essential to provide a new type of herringbone-shaped idler roller assembly for belt conveyors. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a stable, highly adjustable, and easy-to-maintain triangular idler group for belt conveyors, thus solving problems such as deviation, poor adaptability, and high energy consumption inherent in traditional idler groups.

[0005] Preferably, the roller frame is composed of four L-shaped support plates arranged in a concave manner and welded together, and the L-shaped support plates are divided into side A and side B.

[0006] Preferably, the two mounting bases are fitted with sheet metal to enhance the support strength of the tray.

[0007] Preferably, two symmetrical first mounting plates are installed at both ends of the A side of the two bottom support plates, and the first mounting plates are provided with mounting grooves, in which the middle roller is installed.

[0009] Preferably, one of the two top support plates is fitted with a mounting bracket, and the mounting bracket has an installation groove, in which the pressure roller is installed.

[0010] Preferably, the mounting base has mounting holes, and the mounting base is mounted on the support frame via bolts through the mounting holes.

[0011] Preferably, the number of mounting slots opened in the first mounting plate, the second mounting plate, and the fixing frame is at least three sets, and the middle roller, the side roller, and the pressure roller can be selected according to the specific working environment.

[0012] Preferably, the outer edges of the middle roller and the side rollers are both higher than surface B of the pallet.

[0013] This utility model has a novel structure, ingenious design, and is simple and convenient to operate. Compared with the prior art, it has the following advantages:

[0014] 1. Improved stability: The triangular layout ensures even force distribution on the conveyor belt, reducing belt misalignment caused by uneven tension.

[0015] 2. Strong adaptability to working conditions: The multi-set mounting slot design allows for flexible adjustment of the idler roller position to meet the needs of different material characteristics and conveying conditions.

[0023] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1-3 As shown, this utility model provides a triangular idler assembly for a belt conveyor, including a support frame 1, on which two mounting seats 2 are symmetrically mounted. The mounting seats 2 fix the idler frame, which is a recessed frame structure formed by welding four L-shaped support plates 4, divided into an A-side 11 (bottom surface) and a B-side 12 (top surface). Middle rollers 5 are mounted on both sides of the bottom end of the idler frame via first mounting plates 8, side rollers 6 are mounted on both sides of the top end via second mounting plates 9, and a pressure roller 7 is mounted on one side of the top via a fixing frame 10. The three are arranged in a triangular shape, forming a three-point support system.

[0025] The middle roller 5 is located at the bottom center, the side rollers 6 are symmetrically distributed on both sides of the top, and the pressure roller 7 is located on one side of the top, forming a triangular support to balance the tension of the conveyor belt and reduce deviation.

[0026] The outer edges of the middle roller 5 and the side roller 6 are both higher than the B side of the pallet 4 to ensure that the conveyor belt is in full contact with the idler rollers and to avoid material leakage.

[0027] The first mounting plate 8, the second mounting plate 9, and the fixing frame 10 each have at least three sets of mounting slots, allowing the middle roller 5, the side roller 6, and the pressure roller 7 to adjust their positions along the slots to adapt to different material weights, particle sizes, and conveying speed requirements.

[0028] Sheet metal 3 is installed on mounting base 2 to enhance the deformation resistance of support plate 4;

[0029] The recessed frame structure formed by welding the L-shaped support plate 4 improves overall rigidity and extends service life.

[0030] Mounting base 2 is fixed to the mounting holes of support frame 1 by bolts, which facilitates quick disassembly and maintenance.

[0031] The support frame 1 of this device is welded from Q235 steel, and two mounting seats 2 are symmetrically arranged on it. The mounting seats 2 are fixed to the φ14 mounting holes of the support frame 1 by M12 bolts to ensure the overall stability of the idler roller group.

[0032] The roller frame is formed by welding four L-shaped support plates 4 (6mm thick) to form a recessed frame, with side A 11 facing down and side B 12 facing up. The first mounting plate 8 (150mm long × 80mm wide) is welded to both ends of side A of the two bottom support plates 4, and the second mounting plate 9 (120mm long × 60mm wide) is welded to side B of the two top support plates 4. A fixing bracket 10 (100mm long × 50mm wide) is welded to the top of one side.

[0033] The middle roller 5 is fixed by the mounting groove of the first mounting plate 8 (groove length 80mm, spacing 30mm), and the spacing can be adjusted by sliding left and right along the groove (such as adjusting to the maximum spacing of 120mm when conveying large pieces of material).

[0034] Side roller 6: Fixed by the mounting groove of the second mounting plate 9 (groove length 60mm, spacing 20mm), the height can be adjusted to adapt to the conveyor belt groove angle (such as 35°, 45°, etc.).

[0035] Pressure roller 7: It is fixed by the mounting groove (groove length 50mm) of the fixing frame 10 and can move up and down along the groove to adjust the pressing force on the upper layer of the conveyor belt.

[0036] The outer edges of the middle roller 5 and the side roller 6 are 3-5mm higher than the B side of the support plate 4, ensuring that the conveyor belt forms an upward supporting force when it comes into contact with the support rollers, and inhibiting the material from slipping to the sides during the conveying process.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
