Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a belt self-aligning roller frame anti-deviation device with serrated track. Background Technology

[0002] In coal mine production, belt conveyors are key equipment for underground coal transportation, and their stable operation is crucial for ensuring production efficiency and safety. However, belt misalignment has always been a common problem affecting conveyor performance, which can lead to system shutdown or even safety accidents in severe cases.

[0003] Traditionally, self-aligning idler frames are corrected by manually adjusting the position and angle of the idlers and then fixing them with wire. However, in actual operation, due to continuous vibration, material impact, and equipment operating stress, the wire fixing method lacks reliability and is prone to loosening or deformation, causing the idler frame to spring back to its original position and the belt to repeatedly deviate. This problem not only reduces conveying efficiency and exacerbates wear on the belt and idlers, increasing maintenance costs, but also has the potential to cause fires due to overheating from friction, seriously threatening safe production in coal mines.

[0004] Therefore, in view of the unreliability of the existing wire fixing method, the tendency of the self-aligning roller frame to return to its initial state, causing the belt to deviate again, and the possibility of fire caused by overheating due to friction, a belt self-aligning roller frame anti-deviation device with a sawtooth track can be designed. By installing a sawtooth-shaped adjusting track and adjusting fixing rod on the self-aligning roller frame, the stability and reliability of the belt conveyor are significantly improved, ensuring the efficient and safe transportation of coal. Utility Model Content

[0005] To overcome the problems of unreliable wire fixing, which easily leads to repeated belt misalignment and may even cause fire due to overheating from friction.

[0006] The technical solution of this utility model is as follows: a belt self-aligning roller frame anti-deviation device with a serrated track, comprising a serrated adjusting track, an adjusting fixing rod, and a locking block. The serrated adjusting track is fixedly installed on the belt conveyor base frame. The adjusting fixing rod is rotatably connected to the self-aligning roller frame. The adjusting fixing rod has an L-shaped structure, including a long arm pivotally connected to the self-aligning roller frame and a short arm for installing the locking block. The long arm provides a lever arm for the rotation of the adjusting fixing rod. The locking block is adapted to be engaged in any tooth groove of the serrated adjusting track and abuts against the side wall of the tooth groove to limit the lateral movement of the self-aligning roller frame.

[0007] Preferably, the operator first identifies the self-aligning idler frame that needs adjustment due to belt misalignment and observes its current relative position to the conveyor base. A serrated adjustment track is installed on the self-aligning idler frame. The serrated shape provides multiple precise positioning points, allowing the idler to be adjusted to the appropriate position according to the belt misalignment, laying the foundation for subsequent stable fixing. An adjustment fixing rod that fits tightly with the serrated adjustment track is installed. After the idler is adjusted to the correct position, the adjustment fixing rod is rotated so that the locking block engages with a specific serrated position on the serrated adjustment track, effectively limiting the movement of the self-aligning idler frame and ensuring that the self-aligning idler frame remains stable during conveyor operation, preventing belt misalignment.

[0008] Preferably, the serrated adjusting track is fixed to the belt conveyor base frame by bolts or welding.

[0009] Preferably, the adjusting rod and the locking block are made of high-strength alloy steel.

[0010] Preferably, an auxiliary locking component is also included to further reinforce the position of the locking block after it engages with the groove of the serrated adjustment track, preventing it from loosening.

[0011] Preferably, the auxiliary locking component is a friction block, which is disposed on the inner wall of the locking block and / or the serrated adjustment track groove.

[0012] Preferably, the auxiliary locking component is a U-shaped plug, which is inserted into a serrated adjustment track, and the serrated adjustment track has a slot that matches the U-shaped plug.

[0013] The beneficial effects of this utility model are: 1. This unique design, combining a serrated adjusting track with an adjusting fixing rod, provides a completely new solution for fixing the self-aligning idler frame. The multiple precise positioning points of the serrated track allow for more accurate idler position adjustment, while the tight fit between the adjusting fixing rod and the serrations effectively overcomes the instability of traditional wire fixing, ensuring the idler frame remains stable even in harsh operating environments. This significantly improves the fixing effect and can withstand various external forces during conveyor operation, including strong vibrations, material impacts, and stresses generated by equipment operation. Compared to traditional methods, it represents a qualitative leap in stability and reliability, effectively reducing the frequency of belt misalignment and lowering the risk of equipment failure, thus ensuring the continuity and stability of production. It can be flexibly adjusted according to different degrees of belt misalignment and is suitable for various models and specifications of belt conveyors. Whether the misalignment is slight or severe, precise correction can be achieved by adjusting the position of the idler on the serrated track, demonstrating wide application adaptability and operational flexibility, providing reliable assurance for conveyor operation in different production scenarios.

[0014] 2. Installation and operation are relatively simple, and operators can quickly get started. When the belt deviates, simply adjust the position of the idler roller manually, and then lock the adjusting rod into the corresponding serrated position to complete the fixation. No complicated tools or cumbersome operating procedures are required, reducing the labor intensity of operators and improving adjustment efficiency. This makes equipment maintenance more convenient and efficient. The belt can always stay on the correct running trajectory, effectively avoiding material spillage and production interruptions caused by belt deviation, significantly improving conveying efficiency. By reducing unnecessary friction between the belt and the conveyor frame and other components, the service life of the belt is successfully extended, reducing equipment wear and tear costs and reducing the safety risks that may be caused by belt deviation, such as fires. At the same time, it reduces the frequency and cost of equipment maintenance, improves overall production efficiency, and brings significant economic benefits to enterprises.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example 1 Please see Figure 1 and Figure 2This utility model provides an embodiment of a belt self-aligning roller frame anti-deviation device with a serrated track, comprising a serrated adjusting track 1, an adjusting fixing rod 2, and a locking block 4. The serrated adjusting track 1 is fixedly installed on the belt conveyor base frame 6. The adjusting fixing rod 2 is rotatably connected to the self-aligning roller frame 3. The adjusting fixing rod 2 has an L-shaped structure, including a long arm pivotally connected to the self-aligning roller frame 3 and a short arm for installing the locking block 4. The long arm provides a lever arm for the rotation of the adjusting fixing rod 2. The locking block 4 is adapted to be engaged in any tooth groove of the serrated adjusting track 1 and abuts against the side wall of the tooth groove to limit the lateral movement of the self-aligning roller frame 3. The serrated adjusting track 1 is fixed to the belt conveyor base frame 6 by bolts or welding. The adjusting fixing rod 2 and the locking block 4 are made of high-strength alloy steel.

[0019] During operation, the operator first identifies the self-aligning idler frame 3 that needs adjustment due to belt misalignment and observes its current relative position to the belt conveyor base frame 6. A sawtooth-shaped adjusting track 1 is installed on the self-aligning idler frame 3. The sawtooth shape provides multiple precise positioning points, allowing the idler to be adjusted to the appropriate position according to the belt misalignment, laying the foundation for subsequent stable fixing. An adjusting fixing rod 2 that closely matches the sawtooth-shaped adjusting track 1 is installed. After the idler is adjusted to the correct position, the adjusting fixing rod 2 is rotated, causing the locking block 4 to engage with the specific sawtooth position of the sawtooth-shaped adjusting track 1, effectively restricting the movement of the self-aligning idler frame 3 and ensuring that the self-aligning idler frame 3 remains stable during conveyor operation, preventing belt misalignment.

[0020] Example 2 Please see Figure 1 and Figure 3 The difference from Embodiment 1 is that the belt self-aligning roller frame anti-deviation device with serrated track also includes an auxiliary locking component, which is used to further reinforce the position of the locking block 4 after it is locked into the tooth groove of the serrated adjustment track 1 to prevent loosening. The auxiliary locking component is a friction block 51, which is set on the inner wall of the locking block 4 and / or the tooth groove of the serrated adjustment track 1.

[0021] Friction block 51 increases friction. The core advantage of friction block 51 lies in its ability to provide continuous and stable damping friction. Its working principle is not rigid locking, but rather the elastic pressing of high-friction material against the tooth groove wall of the sawtooth adjusting track 1 effectively absorbs and attenuates vibration and impact loads from the conveyor system itself. This significantly prevents the adjusting fixing rod 2 from "skipping teeth" or loosening in the tooth groove due to small-amplitude high-frequency vibration, thus achieving tool-free micro-self-locking and ensuring the long-term positioning reliability of the self-aligning roller frame 3. In addition, compared with pure metal hard contact, the intervention of friction block 51 reduces direct wear between metal parts and gaps caused by wear, extending the service life of core components. Its structure is simple, low-cost, and can automatically play an anti-loosening role without additional operation, making it safe and efficient.

[0022] Example 3 Please see Figure 1 and Figure 4 The difference from Embodiment 1 is that the belt self-aligning roller frame anti-deviation device with serrated track also includes an auxiliary locking component, which is used to further reinforce the position of the locking block 4 after it is locked into the tooth groove of the serrated adjustment track 1 to prevent loosening. The auxiliary locking component is a U-shaped plug 52, which is inserted into the serrated adjustment track 1. The serrated adjustment track 1 has a slot that matches the U-shaped plug 52.

[0023] The core advantage of the U-shaped plug 52 lies in its absolutely reliable rigid mechanical interlock, which provides extremely high safety. Once inserted into the serrated adjustment rail 1, its sturdy arm will directly block the movement path of the locking block 4, forming a physical barrier. This locking method can fundamentally eliminate any risk of loosening or disengagement caused by strong vibration, accidental impact, or huge load fluctuations. Its stability is unparalleled. Its structure is simple and intuitive, and its status is clear (locking upon insertion and adjustment upon removal). Operators can visually confirm the locking status from a distance, which greatly improves the safety and reliability of operation. It is very suitable for heavy industrial occasions with harsh environments and extremely high safety requirements.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
