Description

Technical Field

[0001] This utility model relates to the technical field of anti-deviation devices, and in particular to an anti-deviation device for belt conveyors in fully mechanized mining faces. Background Technology

[0002] In fully mechanized coal mining, belt conveyors are the core transportation equipment connecting the coal mining machine, scraper conveyor, and surface storage system, undertaking the critical task of continuous coal transfer. Their operational stability directly determines the production capacity (the hourly transport capacity of a single high-yield fully mechanized coal mining face belt conveyor can reach 3,000-5,000 tons) and operational safety. However, the fully mechanized coal mining face has a harsh environment (narrow space, high dust concentration, and severe equipment vibration), and the belt is subjected to high loads for a long time (coal impact and continuous friction). It is prone to "deviation" failure due to uneven belt tension, roller wear, and material eccentricity, which has become the main bottleneck restricting the efficient operation of belt conveyors. The existing belt deflection prevention device for fully mechanized mining faces has several drawbacks. Traditional devices often use a "fixed vertical roller" or "manual bolt adjustment bracket" design. The fixed vertical roller can only passively block slight deflection and cannot actively adjust its position according to the direction and degree of deflection. When the belt deviates dynamically, the vertical roller cannot respond in time and is easily moved by the belt, thus losing its deflection prevention function. Therefore, the above-mentioned technical problems need to be solved. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a belt deflection prevention device for fully mechanized mining faces.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a belt conveyor anti-deviation device for fully mechanized mining faces, comprising a fixed rod located inside the belt conveyor of the fully mechanized mining face, two fixed seats being installed between the fixed rods by positioning bolts, a column being installed between the fixed seats on the same side by bolts, a moving mechanism being installed on one side of the column, and internal threaded holes being equally spaced on the same side of the moving mechanism and the column, and an anti-deviation mechanism being installed between the moving mechanism and the column.

[0005] Preferably, the moving mechanism includes an electric telescopic rod installed on one side of two fixed seats. The telescopic ends of the two electric telescopic rods are respectively fixed to the adjusting frame. The adjusting frame is slidably installed between the two fixed seats. The fixed seats are provided with moving slots at both the upper and lower ends of the adjusting frame.

[0006] Preferably, each of the moving slots has a moving block slidably installed therein, and each moving block is fixedly connected to the adjusting frame.

[0007] Preferably, both the adjusting frame and the column are provided with guide grooves, and a guide rod is fixedly connected vertically upward in the guide groove.

[0008] Preferably, the anti-deviation mechanism includes lifting blocks movably sleeved on the guide rod, a rotating rod rotatably mounted between the lifting blocks, and a guide roller sleeved on the rotating rod.

[0009] Preferably, a fixing threaded hole is provided on one side of the movable block at equal intervals with the internal threaded hole on the column and the adjusting frame, and a fixing bolt is installed between the fixing threaded hole and the internal threaded hole by threaded connection.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of the electric telescopic rod, the adjusting frame, and the moving block, facilitates the active adjustment of the position of the anti-deviation mechanism, improves the timeliness and accuracy of the anti-deviation response, and thus enables the function of actively adapting to the dynamic deviation of the belt. Furthermore, through the cooperation of the lifting block, the rotating rod, the guide roller, and the adjusting frame, it facilitates the enhancement of the corrective force on the misaligned belt, improves the stability of the anti-deviation mechanism, and thus enables the function of dynamically adapting to the belt's operating state and continuously playing the anti-deviation role. Ultimately, it solves the problem that traditional devices can only passively block slight deviations and cannot actively respond to dynamic deviations, leading to the failure of the anti-deviation mechanism.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4 This utility model discloses a belt derailment prevention device for fully mechanized mining faces, comprising a fixed rod 1 located inside the belt conveyor of the fully mechanized mining face. Two fixed seats are installed between the fixed rod 1 by positioning bolts. A column 2 is installed between the fixed seats on the same side by bolts. A moving mechanism is installed on one side of the column 2. The moving mechanism and the column 2 are both provided with internally threaded holes 4 at equal intervals on the same side. An anti-derailment mechanism is installed between the moving mechanism and the column 2. The fixed rod 1, fixed seats, column 2, moving mechanism, internally threaded holes 4, and anti-derailment mechanism facilitate the construction of the overall framework of the belt derailment prevention device for fully mechanized mining faces, providing a basic structure for the installation and position adjustment of the anti-derailment mechanism, and initially forming the core functional carrier for belt derailment prevention. The moving mechanism includes a component installed between the two fixed seats. The two electric telescopic rods 5 on the side are fixed at their telescopic ends to the adjusting frame 7. The adjusting frame 7 is slidably installed between two fixed seats. The fixed seats are provided with moving grooves 6 at both the upper and lower ends of the adjusting frame 7. Through the electric telescopic rods 5, the adjusting frame 7, and the moving grooves 6, the telescopic power of the electric telescopic rods 5 can be used to drive the adjusting frame 7 to move along the moving grooves 6, thereby adjusting the horizontal position of the anti-deviation mechanism and adapting to belts of different widths or deviation conditions. Moving blocks 9 are slidably installed in the moving grooves 6. The moving blocks 9 are fixed to the adjusting frame 7. Through the moving blocks 9, the adjusting frame 7, and the moving grooves 6, the adjusting frame 7 can be assisted to slide stably along the moving grooves 6, avoiding tilting or deviation when the adjusting frame 7 moves, and ensuring the stability of the horizontal position adjustment of the anti-deviation mechanism.

[0015] In this invention, both the adjusting frame 7 and the column 2 are provided with guide grooves. A guide rod 12 is vertically fixed upward in the guide groove. Through the adjusting frame 7, column 2, guide groove, and guide rod 12, a vertical guide track is provided for the lifting and lowering action of the anti-deviation mechanism, preventing misalignment during lifting and lowering and ensuring the accuracy of its height adjustment. The anti-deviation mechanism includes a lifting block 10 movably sleeved on the guide rod 12. A rotating rod 11 is rotatably installed between the lifting blocks 10. A guide roller 8 is sleeved on the rotating rod 11. Through the lifting blocks 10, rotating rod 11, guide roller 8, and guide rod 12, the guide roller 8 can be used to facilitate the lifting and lowering action of the anti-deviation mechanism. The moving block 9 fits against the side of the belt and guides the belt back to the correct position when it deviates from its designated path. At the same time, the lifting block 10 can be adjusted in height along the guide rod 12 to accommodate belts of different thicknesses and achieve the belt deviation prevention function. The moving block 9 has fixed threaded holes equidistantly opened on one side corresponding to the internal threaded holes 4 on the column 2 and the adjusting frame 7. The fixed threaded holes and the internal threaded holes 4 are connected by a fixing bolt 3. Through the moving block 9, the fixed threaded holes, the internal threaded holes 4, and the fixing bolt 3, it is easy to adjust the position of the guide roller 8 between the column 2 or the adjusting frame 7 as required, prevent the adjusting frame 7 from shifting during belt operation, and ensure the stability of the anti-deviation mechanism.

[0016] Working Principle: When using this invention, firstly, the fixing rod 1 is installed in the fully mechanized mining face using bolts or welding to form the basic fixed structure of the device. Then, the belt is passed over the upper end of the guide roller 8 between the columns 2, and then over the lower end of the guide roller 8 between the adjusting frames 7, completing the initial assembly of the device and the belt. Next, the position of the lifting block 10 on the guide rod 12 is adjusted to adjust the horizontal height of the guide roller 8 to match the thickness of the belt. After the height adjustment is completed, the fixing bolt 3 is used to fix the position of the lifting block 10 by passing through the fixing threaded hole on one side of the moving block 9 and the corresponding internal threaded hole 4 on the column 2 and the adjusting frame 7, ensuring the stability of the height of the guide roller 8. When the belt deviates during operation, the electric telescopic rod 5 is activated. Its telescopic end drives the adjusting frame 7 to move horizontally along the moving slots 6 opened at both ends of the fixed seat via the moving block 9 (the moving block 9 is fixedly connected to the adjusting frame 7, which can help the adjusting frame 7 slide stably and avoid tilting and deviation). The movement of the adjusting frame 7 will drive the guide roller 8 installed on it to move synchronously. The guide roller 8 and the side of the belt will generate a constraint force. Under the guidance of this constraint force, the belt will gradually return to the center line, realizing the deviation correction. Throughout the process, the normal operation of the belt is continuously ensured through the coordinated action of the fixed rod 1, fixed seat, column 2, moving mechanism and anti-deviation mechanism. When the belt no longer needs to use the device, the components can be disassembled or adjusted by removing the fixing bolts 3, etc., to adapt to different working requirements.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
