Description

Technical Field

[0001] This utility model relates to the field of idler technology, and more specifically, to a self-aligning idler structure for a reversible belt conveyor. Background Technology

[0002] As the core equipment for conveying bulk materials in industries such as mining, ports, and building materials, the operational stability of belt conveyors directly affects production efficiency and safety. With the increasing demand for bidirectional conveying in industrial production, such as the round-trip transportation of materials in underground mines and the loading and unloading of bulk cargo in ports, reversible belt conveyors are gradually replacing traditional unidirectional conveyors and becoming the mainstream choice.

[0003] When transporting goods on a conveyor belt, the belt will tilt when it deviates. Currently, the way to correct this is to limit the belt with friction rollers so that the belt moves back to the center position for transport. However, this method causes serious wear on the belt, and over time the belt will become unusable due to wear. Therefore, a reversible belt conveyor self-aligning idler structure is proposed to solve this problem. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a reversible belt conveyor self-aligning idler structure that overcomes or at least partially solves the above technical problems.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a self-aligning idler structure for a reversible belt conveyor, including a lower crossbeam and an upper crossbeam installed outside the lower crossbeam. Three rollers are arranged on the upper surface of the upper crossbeam, and a stop roller is installed on the upper crossbeam. The position of the stop roller installed on the upper crossbeam is changed by a rotating assembly, which is used to limit the belt in different conveying directions.

[0007] In a preferred embodiment, a positioning plate is fixedly installed at the end of the lower crossbeam, and mounting holes are provided on the outer surface of the positioning plate.

[0008] In a preferred embodiment, positioning seats are fixedly installed at both ends of the upper crossbeam at positions symmetrical to each other with the center line of the roller in the middle position as the axis of symmetry, and the remaining rollers are installed on the side of the positioning seats.

[0009] In a preferred embodiment, the roller in the middle position is horizontally mounted at the midpoint of the upper crossbeam surface, and the other two rollers are both set to an inclined state.

[0010] In a preferred embodiment, vertical supports are fixedly installed at both ends of the roller in the middle position for stable connection to the other two rollers.

[0011] The reversible belt conveyor self-aligning idler structure provided by this utility model has the following advantages:

[0012] By using a stop roller that can be positioned at the end of the upper crossbeam, the stop roller can be moved to the front or rear of the upper crossbeam during use. This ensures that when the belt is tilted, the side will touch the stop roller. Under the limit of the stop roller, the belt can be moved back to the center position for conveying, avoiding belt wear and greatly reducing operating costs. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] Reference Figures 1-2 This utility model provides a technical solution: a reversible belt conveyor self-aligning idler structure, including a lower crossbeam 1 and an upper crossbeam 2 installed outside the lower crossbeam 1. Three rollers 3 are arranged on the upper surface of the upper crossbeam 2, and a stop roller 10 is installed on the upper crossbeam 2. The stop roller 10 is installed in a rotating component 4 to change the position of the upper crossbeam 2, which is used to limit the belt in different conveying directions. The lower crossbeam 1 is made of Q355B low alloy structural steel, which has high yield strength and better impact resistance than ordinary carbon steel, and can withstand the bidirectional load of the upper crossbeam 2 and the material. The surface is hot-dip galvanized to improve the corrosion resistance in open-air / humid environments.

[0023] The upper crossbeam 2 is made of Q235A carbon steel, which is moderately priced and has good plasticity. The surface is powder-coated to prevent dust adhesion and slight corrosion.

[0024] Roller 3 is made of stainless steel. The outer surface of roller 3 is polished and coated with cold-hardened cast iron to resist bidirectional wear.

[0025] The rotating assembly 4 can be a round shaft 41 and a rotating arm 42. The round shaft 41 is fixedly installed at the bottom of the upper crossbeam 2, and the rotating arm 42 is rotatably installed at the bottom of the upper crossbeam 2 via the round shaft 41. The guide roller 10 is rotatably installed at the upper end of the rotating arm 42. The rotating arm 42 is stably connected to the upper crossbeam 2 via the pin 9.

[0026] When in use, this equipment uses the guide roller 10 to correct the belt that has deviated on the roller 3, and can adjust the belt back to the center position, so that the belt can be conveyed normally, and thus the material on the belt can be conveyed normally.

[0027] First, adjust the position of the guide roller 10 according to the direction of belt movement. For example, when the belt is conveyed forward on the roller 3, the guide roller 10 needs to be moved to the rear side of the upper crossbeam 2. Conversely, the guide roller 10 will be moved to the front side. By pulling the pin 9 out of the upper crossbeam 2 and rotating the rotating arm 42, the position of the rotating arm 42 can be moved, causing the position of the guide roller 10 to change. After determining the position of the guide roller 10, the pin 9 is used to limit the rotating arm 42. When the belt deviates and moves towards the position of the guide roller 10, the belt can be moved back to the center position under the restriction of the guide roller 10.

[0028] In a preferred embodiment, a positioning plate 5 is fixedly installed at the end of the lower crossbeam 1, and a mounting hole 6 is provided on the outer surface of the positioning plate 5. The positioning plate 5 is made of Q355B low alloy structural steel to avoid cracking at the weld due to uneven stress. The positioning plate 5 is set in an inverted L shape. The positioning plate 5 is welded to the end of the lower crossbeam 1. Before welding, the contact surface between the end of the lower crossbeam 1 and the positioning plate 5 needs to be derusted and coated with welding anti-spatter agent. After welding, the weld is subjected to magnetic particle testing to eliminate defects such as cracks and pores, and to prevent the weld from falling off during long-term use.

[0029] Mounting holes 6 are provided on the top of each positioning plate 5, and each positioning plate 5 has two mounting holes 6, which penetrate the interior of the positioning plate 5.

[0030] In a preferred embodiment, positioning seats 7 are fixedly installed at both ends of the upper crossbeam 2 at positions symmetrical to each other with the center line of the roller 3 in the middle position as the axis of symmetry. The remaining roller 3 is installed on the side of the positioning seat 7. The positioning seat 7 is made of Q235A carbon steel and is formed by casting and machining. Because Q235A carbon steel has good plasticity, it is easy to process the shaft holes and fixing bolt holes required for the installation of the roller 3. It also has strong compatibility when bolted to the upper crossbeam 2 and can withstand the instantaneous load caused by the impact of materials such as ore and coal falling during reversible conveying, thus avoiding the roller 3 from falling off due to the breakage of the positioning seat 7.

[0031] In a preferred embodiment, the middle roller 3 is horizontally installed at the middle section of the surface of the upper crossbeam 2, and the other two rollers 3 are both set to an inclined state, with the two side rollers 3 inclined outwards from the conveyor belt. The inclination angle needs to be precisely set according to the width of the conveyor belt and the running speed.

[0032] Vertical supports 8 are fixedly installed at both ends of the middle roller 3 to stably connect the other two rollers 3. The vertical supports 8 need to bear the radial load of the middle roller 3 and the lateral pressure of the two rollers 3 at the same time. They are made of Q235B low alloy structural steel, forged and machined, and can withstand the combined load generated by the material impact and the bidirectional force of the roller 3 during reversible conveying. At the same time, they have excellent welding performance and can form a high-strength connection with the middle positioning seat 7 and the upper crossbeam 2 to avoid breakage or deformation during long-term use.

[0033] Example 2

[0034] Reference Figures 3-4The rotating assembly 4 can also be a turntable 411, a plug hole 412, and a plug rod 413. The turntable 411 is fixedly installed at the bottom of the upper crossbeam 2, and a circular plate 11 is fixedly installed on the surface of the lower crossbeam 1 at a position corresponding to the turntable 411 at the bottom of the upper crossbeam 2. The turntable 411 is rotatably connected to the circular plate 11 through a rotating shaft. The surfaces of the turntable 411 and the circular plate 11 are respectively provided with circular holes of the same diameter and corresponding positions, and a plug rod 413 is inserted into the inside of the circular hole to stably connect the turntable 411 and the circular plate 11 together. After changing the position of the guide roller 10, the upper crossbeam 2 is limited. The belt can be limited by the guide roller 10 and the belt can be returned to the center position.

[0035] In actual use, the position of the upper crossbeam 2 is adjusted in advance according to the direction of the belt conveying on the roller 3, and the position of the guide roller 10 is changed. At this time, the belt is simply lifted up so that it does not contact the roller 3, and space is left for the upper crossbeam 2 to rotate. The plug rod 413 is pulled out from the turntable 411, and the upper crossbeam 2 can be rotated. Rotating the upper crossbeam 2 180 degrees can change the position of the guide roller 10 to meet the needs of conveying the belt in different directions.

[0036] After the upper crossbeam 2 is rotated, the plug rod 413 is inserted into the interior of the turntable 411 and the circular plate 11 to limit the upper crossbeam 2, and then the belt that has deviated can be corrected by the guide roller 10.
