Description

Technical Field

[0001] The utility model relates to the technical field of coal conveyor belts, in particular to a device for preventing a coal conveyor belt from deviating. Background Art

[0002] Belt conveyors are conveying systems used to transport loose materials or finished goods. They are widely used in various manufacturing enterprises due to their low operating costs, wide adaptability, and high production capacity. They are the main transportation equipment for transporting bulk materials over short distances. Especially in coal mining, where coal is heavy, it is necessary to transfer it from the mining end to other locations, and using belt conveyors for this transfer is essential. During operation, coal slag easily enters the non-working surface of the coal conveyor belt, which adheres to the belt and causes the belt to deviate. Furthermore, it is difficult to ensure a balanced amount of coal on all parts of the coal conveyor belt surface during operation, which results in an uneven load on the coal conveyor belt. Under the influence of the coal's gravity, the coal conveyor belt often deviates to one side.

[0003] Some existing belt conveyors are equipped with anti-deviation mechanisms. If the belt deviates, the belt can be prevented from deviating by adjusting the inclination angle of the rollers on both sides of the coal conveyor belt, allowing the belt to resume normal operation. However, adjusting the inclination angle of the rollers on both sides of the coal conveyor belt has limited ability to adjust the belt after deviation, and the adjustment speed is slow. Furthermore, when adjusting the inclination angle of the rollers on both sides of the coal conveyor belt, the side of the coal conveyor belt will be lifted, causing the coal on the coal conveyor belt to tilt at a certain angle, resulting in some coal spilling. The spilled coal enters the non-working surface of the coal conveyor belt, affecting the normal operation of the belt conveyor. Utility Model Content

[0004] In order to solve the technical problems in the prior art that the adjustment speed of the coal conveyor belt by adjusting the inclination angle of the rollers on both sides of the coal conveyor belt is slow, and it is easy to cause the coal on the coal conveyor belt to tilt at a certain angle, resulting in some coal spilling and affecting the normal operation of the belt conveyor, the utility model provides the following technical solutions.

[0005] The utility model discloses a coal conveyor belt anti-deviation device, comprising several fixed blocks connected to the belt conveyor, the fixed blocks are fixedly connected to two relatively arranged support plates, several connecting plates are fixedly connected between the two support plates, a first support plate with at least two lifting drive members on the upper portion is fixedly connected between two adjacent connecting plates, at least two lifting plates respectively connected to the output ends of the two lifting drive members are slidably connected between the two support plates, a first correcting component and a second correcting component with opposite correcting directions are respectively fixedly connected on the upper portion of each of the lifting plates, the first correcting component comprises a support plate fixedly connected to the lifting plate and side plates arranged obliquely on both sides of the support plate, the support plate and the side plates are respectively rotatably connected to a horizontal correcting roller with a threaded portion on the outer periphery and a side correcting roller connected to an infrared sensor.

[0006] As a further technical solution, the outer periphery of the side correcting roller is provided with a thread having the same direction as the thread of the horizontal correcting roller.

[0007] As a further technical solution, the threaded portion is a threaded protrusion or a threaded groove.

[0008] As a further technical solution, a plurality of lifting slots are provided on the inner side of the bracket plate, and lifting sliders matching the lifting slots are provided at both ends of the lifting plate.

[0010] As a further technical solution, a plurality of second support plates are fixedly connected between two adjacent connecting plates, and the second support plates are fixedly connected to support sleeves fixedly connected to the lower portion of the lifting plate.

[0011] As a further technical solution, columns are fixedly provided on both sides of the lifting plate, and the upper ends of the columns are fixedly connected to the lower parts of the side plates.

[0012] The beneficial effects of the present invention are as follows: the present invention is connected to the bracket of the belt conveyor through a fixed block, and is slidably connected to a lifting plate through two relatively arranged bracket plates. The lower part of the lifting plate is connected to a lifting drive member, which can move the lifting plate up and down, and drive the first correcting member or the second correcting member to press upward or downward away from the coal conveyor belt. When the infrared sensor detects that the coal conveyor belt has deviated, the first correcting member or the second correcting member can automatically correct the deviation in different directions respectively, and the horizontal correcting roller and the two side correcting rollers correct the deviation in the horizontal direction and the two sides of the coal conveyor belt at the same time, thereby improving the speed and effect of the correction adjustment of the coal conveyor belt.

Multiple devices can be evenly spaced or distributed in other ways. The utility model does not impose any particular restrictions on their distribution on the belt conveyor.

[0020] In a preferred embodiment, two connecting plates 3 are fixedly connected between the two support plates 1, and a first support plate 301 is fixedly connected between two adjacent connecting plates 3. At least two lifting drive members 4 are provided on the upper portion of the first support plate 301. At least two lifting plates 6, each connected to the output ends of the two lifting drive members 4, are slidably connected between the two support plates 1. The lifting drive members 4 are short-stroke, high-load drive members used to drive the lifting plates 6 up and down. The lifting drive members 4 can be electric cylinders, hydraulic cylinders, or pneumatic cylinders, which are not particularly limited in the present invention.

[0021] like Figure 2 and Figure 3 As shown, in a preferred embodiment, a first correcting component 7 and a second correcting component 8 with opposite correcting directions are fixedly connected to the upper portions of the two lifting plates 6. The first correcting component 7 and the second correcting component 8 automatically correct the left and right deviations of the coal conveyor belt, respectively. The two lifting drive members 4 are used to drive the lifting and lowering of the first correcting component 7 and the second correcting component 8, respectively. The first correcting component 7 includes a support plate 701 fixedly connected to the lifting plate 6. The support plate 701 has inclined side plates 702 fixedly connected on both sides. The support plate 701 is rotatably connected to a horizontal correcting roller 703. Both side plates 702 are rotatably connected to side correcting rollers 704.

[0022] The side correcting roller 704 is connected to an infrared sensor 10, which is used to monitor the deviation direction of the coal conveyor belt. When it is detected that the coal conveyor belt is deviating, the lifting drive part 4 drives the lifting plate 6 to rise, so that the horizontal correcting roller 703 and the side correcting roller 704 on the upper part of the first correcting component 7 are pressed against the coal conveyor belt. The horizontal correcting roller 703 and the side correcting roller 704 guide the running direction of the coal conveyor belt and automatically correct the deviated coal conveyor belt.

[0023] The horizontal correction roller 703 is provided with a threaded portion 705, which is used to guide the running direction of the coal conveyor belt and correct its deviation direction. The outer periphery of the side correction roller 704 is provided with a thread that is consistent with the thread direction of the horizontal correction roller 703. The threaded portion 705 can be a threaded protrusion or a threaded groove. Its thread direction can guide the coal conveyor belt to rotate left or right to correct the deviation direction. The first correction direction 7 can be used to correct left deviation or right deviation, and there is no special limitation on it. As long as the first correction component 7 and the second correction component 8 have inconsistent correction directions for the left and right deviations, the first correction component 7 and the second correction component 8 only have opposite thread directions, and the other structures are the same. Therefore, the second correction component 8 will not be described in detail.

[0024] In a preferred embodiment, a plurality of lifting chutes 101 are provided on the inner side of the support plate 1. Lifting blocks 601 are provided at both ends of the lifting plate 6 to match the lifting chutes 101. When the lifting drive 4 drives the lifting plate 6 up and down, the lifting blocks 601 slide up and down within the lifting chutes 101. A limit plate 9 is provided above the lifting chutes 101 to prevent the lifting chutes 101 from being blocked by coal.

[0025] In a preferred embodiment, a second support plate 302 is provided on both sides of the first support plate 301.
