Description

Technical Field

[0001] This utility model relates to the technical field of coal mine transportation equipment, specifically to a conveying anti-deviation device in coal mine electromechanical transportation. Background Technology

[0002] In underground or surface transportation systems of coal mines, conveyor belts are a common type of continuous transportation equipment, widely used for the transfer and stockpiling of raw coal.

[0003] In practical applications, due to factors such as unstable coal mine material drop points, uneven belt tension, or uneven material load, conveyor belts are prone to deviation, especially when there is a large weight difference between the coal mines on both sides of the center line, which can easily cause the conveyor belt to shift laterally and affect transportation efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a conveying anti-deviation device for electromechanical transportation in coal mines.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] Anti-deviation devices for conveying equipment in coal mine electromechanical transportation include:

[0007] A fixed plate is set above the conveyor belt along the width direction of the conveyor belt, and it has a curved groove that is low at both ends and high in the middle;

[0008] A tilting plate is set along the conveyor belt conveying direction. One end of the plate has two locking rods that slide and engage with the curved groove. Initially, the lowest end of the tilting plate is higher than the height of the coal mine on the conveyor belt.

[0009] The screw drive mechanism is set along the width direction perpendicular to the conveyor belt body. It has a lever plate located between two locking rods. After the lever plate drives the two locking rods to slide along the curved groove, the lowest end of the flip plate is lower than the height of the coal mine on the conveyor belt.

[0010] Two load cells are located on the front side of the aforementioned tilting plate near the conveyor belt's conveying direction, and the two load cells are located on the left and right sides of the conveyor belt's centerline, respectively. The signals from the load cells control the movement direction of the toggle plate.

[0011] Preferably, it also includes a fixing rod, which is disposed above the conveyor belt along the width direction of the conveyor belt, and the fixing rod is located on the front side of the fixing plate near the conveyor belt conveying direction.

[0012] Preferably, the middle part of the flip plate on the side away from the snap-fit ​​rod is rotatably connected to the fixed rod.

[0013] Preferably, when the aforementioned lever pushes the locking rod to slide in the curved groove, the side of the aforementioned flip plate with the lower height moves closer to the conveyor belt, and the end of the flip plate near the locking rod moves towards the edge of the conveyor belt.

[0014] Preferably, the side of the tilting plate with the lower height is parallel to the conveyor belt.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By setting up a cooperative structure between the tilting plate and the curved groove, and combining it with the feedback control of two weighing sensors, the tilting plate can automatically adjust its posture and position according to the weight deviation of the coal mines on both sides of the conveyor belt, guiding the coal mines in the middle to the side with a lighter load, thereby dynamically balancing the conveying load, reducing the problem of belt deviation caused by uneven load during the conveying process, and reducing the impact on transportation efficiency.

[0017] 2. As the clamping rod slides along the curved groove, the tilting plate can achieve a composite motion of "sliding + rotation", forming a natural tilt state, which is more conducive to effectively guiding the coal piled up in the middle, avoiding excessive material accumulation or blockage, and improving the stability of conveying.

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] Example

[0026] like Figures 1-2 As shown, the anti-deviation device for coal mine electromechanical transportation includes a fixed plate 3, a tilting plate 4, a screw drive mechanism, and two weighing sensors. It also includes a conveyor belt body 1, which is used to transport coal. The screw drive mechanism can be a motor-driven screw drive system that moves the guide plate.

[0027] In one embodiment, such as Figures 1-2 As shown, the fixed plate 3 is set above the conveyor belt along the width direction of the conveyor belt. It has a curved groove 31 that is low at both ends and high in the middle. The flip plate 4 is set along the conveying direction of the conveyor belt. One end of the flip plate has two locking rods 41 that are slidably engaged with the curved groove 31. Initially, the lowest end of the flip plate 4 is higher than the height of the coal mine on the conveyor belt. The screw drive mechanism is set along the width direction perpendicular to the conveyor belt body 1. It has a lever plate located between the two locking rods 41. After the lever plate drives the two locking rods 41 to slide along the curved groove 31, the lowest end of the flip plate 4 is lower than the height of the coal mine on the conveyor belt. Two weighing sensors are located on the front side of the flip plate 4 near the conveying direction of the conveyor belt. The two weighing sensors are located on the left and right sides of the center line of the conveyor belt, respectively. The signals from the weighing sensors control the movement direction of the lever plate. A tilting plate 4 is connected to a fixed rod 2 and a fixed plate 3. With the cooperation of a locking rod 41 and a curved groove 31, and under the constraint of the fixed rod 2, the end of the tilting plate 4 closest to the fixed plate 3 can move towards both sides of the conveyor belt body 1. Simultaneously, the height of the tilting plate 4 is reduced, allowing it to contact and act on the coal ore. This allows adjustment of coal ore accumulated near the center of the conveyor belt body 1. Furthermore, the tilting plate 4 can be tilted as the locking rod 41 moves along the curved groove 31, facilitating the guidance of accumulated coal ore and reducing the probability of coal ore accumulating near the center of the fixed rod 2.

[0028] During the coal conveying process, two weighing sensors located on both sides of the center line at the bottom of the tilting plate 4 compare the weight of the coal on both sides of the center line of the conveyor belt. For the lighter side, the tilting plate 4 is adjusted to guide the coal in the center position to the lighter side, so as to realize the dynamic balance adjustment of the material load, so as to balance the weight on both sides, reduce the probability of conveyor belt deviation, and improve the stability of the coal conveying process.

[0029] In one embodiment, such as Figures 1-2As shown, it also includes a fixing rod 2, which is positioned above the conveyor belt along the width direction of the conveyor belt. The fixing rod 2 is located on the front side of the fixing plate 3 near the conveyor belt's conveying direction. A fixing rod 2 arranged along the width direction of the conveyor belt is set in front of the fixing plate 3 near the conveying direction. This fixing rod 2 is positioned in front of the fixing plate 3 and is installed as a whole on the structural frame above the conveyor belt to constrain and support the movement of the tilting plate 4. The middle part of the side of the tilting plate 4 away from the locking rod 41 is rotatably connected to the fixing rod 2. The middle part of the end of the tilting plate 4 away from the locking rod 41 is rotatably connected to the fixing rod 2 through a rotating shaft structure, so that when the lever pushes the locking rod 41 to slide, the tilting plate 4 can change its angle around the fixing rod 2.

[0030] In one embodiment, such as Figures 1-2 As shown, when the lever pushes the locking rod 41 to slide in the curved groove 31, the side of the tilting plate 4 with its lower height moves closer to the conveyor belt, and the end of the tilting plate 4 near the locking rod 41 moves towards the edge of the conveyor belt. When the lever pushes the locking rod 41 to slide in the curved groove 31, the displacement of the locking end causes the tilting plate 4 to move closer to the edge of the conveyor belt, while one side of it tilts downwards and approaches the conveyor belt body 1. The side of the tilting plate 4 with its lower height is parallel to the conveyor belt. After the tilting plate 4 slides to the end of the curved groove 31, its lower side position remains parallel to the surface of the conveyor belt body 1, and there is space between them for small pieces of coal to pass through, thereby improving the stable and uniform guiding contact of the material.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
