Description

Technical Field

[0001] The present invention relates to the technical field of conveyors, and in particular to a belt conveyor with a displacement detection function and a use method thereof. Background Art

[0002] In the process of transporting coal in the mine, the main inclined belt conveyor is often used. The main inclined belt conveyor is responsible for the coal lifting task of the entire mine and can quickly complete the transportation of coal.

[0003] In the prior art, belt conveyors still have the following deficiencies during transportation:

[0004] 1. As production extends, the main shaft belt roller is subjected to greater force, and the roller is unevenly stressed and moves to one side, which increases the frequency of roller bearing damage. Each treatment requires a lot of manpower and material resources, and each time the production is affected for more than 10 hours, which seriously affects the production rhythm of the mine, causing a lot of economic losses and is not conducive to mine safety production.

[0005] 2. When the roller is offset, in order to detect the degree of wear on the roller surface, the roller needs to be disassembled. If the wear is large, replace it with a new roller; if the wear is small, repair the roller. The disassembly process is extremely troublesome, and it needs to be tested later, which takes a lot of time and affects the production efficiency of the mine;

[0006] In view of the above problems, the present invention document proposes a belt conveyor with a displacement detection function and a method for using the same. Summary of the invention

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] Example 1

[0048] Reference Figure 1 , Figure 2 and Figure 4 , a belt conveyor, which is used in the field of belt conveyors, comprises a frame composed of two bracket plates 1, two rollers 2 are rotatably connected in the frame, and the two rollers 2 are connected by a conveyor belt 3. On one side of the frame, a driving motor 4 is fixed through a mounting frame, and its output shaft is fixedly connected to one end of one of the rollers 2 to drive the rollers 2 and the conveyor belt 3 to operate.

[0049] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The control structure includes two first transverse plates 5 fixed in the frame, and the two first transverse plates 5 are respectively located below the two rollers 2. A U-shaped plate 6 is slidably connected to the top of each first transverse plate 5, and one side of the bottom of the roller 2 extends into the U-shaped plate 6. Two balls 7 are arranged in the U-shaped plate 6, which are respectively rollingly arranged on the inner walls of the two sides of the U-shaped plate 6 that are close to each other, and touch the two end faces of the roller 2. Installation boxes 8 are arranged on both sides of the U-shaped plate 6, which are fixed on the inner wall of the frame that is away from each other. A plurality of fixed rods 11 are fixed in the installation box 8, and the same movable disk 13 is slidably sleeved on the plurality of fixed rods 11, and a first tension spring 14 is provided to connect the installation box 8 and the movable disk 13 to provide a reset force. A push rod 16 is fixed on the side of the movable disk 13 close to the U-shaped plate 6, and one end of the push rod 16 slides and extends to the outside of the installation box 8 and touches the U-shaped plate 6. A pressure sensor 15 is also fixed on the movable plate 13 , and the pressing plate 12 adjusted by the hexagon socket bolt 9 cooperates with the pressure sensor 15 to send a signal when the drum 2 deviates.

[0050] Specifically, when the drum 2 deviates during rotation, its end surface pushes the U-shaped plate 6 to move through the ball 7, and the U-shaped plate 6 pushes the moving plate 13 and the pressure sensor 15 to move through the push rod 16. When the pressure sensor 15 is squeezed by the pressing plate 12, a signal is sent to control the driving motor 4 to stop running, and the buzzer is triggered for warning.

[0051] Reference Figure 2 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 The cleaning and detection structure includes two rotating shafts 18 rotatably connected to the inner walls on both sides of the frame, and a rotating disk 19 is fixed at one end of each rotating shaft 18. A rotating rod 20 and a screw rod 22 are rotatably connected between the two rotating disks 19, and a cylinder brush 21 is fixed on the rotating rod 20 for cleaning the outer wall of the cylinder 2. A moving seat 24 is threadedly connected to the screw rod 22, and a second laser rangefinder 25 is fixed on the end of the moving seat 24 away from the cylinder brush 21 for detecting the degree of wear of the cylinder 2. A gear ring 28 is fixedly sleeved on the outer wall of the cylinder 2, and a second gear 27 is rotatably connected to the inner wall of one side of the frame, which meshes with the gear ring 28 and the first gear 26 at one end of the rotating rod 20 and the screw rod 22. A bending collection plate 29 is also fixed between the two rotating disks 19, and a comb 30 is fixed on the top of the plate through a cross bar to remove materials and adhesives on the cylinder brush 21.

[0052] Specifically, when the drum 2 rotates, the gear ring 28, the second gear 27 and the first gear 26 cooperate to drive the rotating rod 20 and the cylinder brush 21 to rotate counterclockwise to remove the materials and adhesives on the outer wall of the drum 2. At the same time, the comb 30 removes the materials and adhesives on the cylinder brush 21 and makes them fall into the bent collection plate 29.

[0053] Reference Figure 2 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 The cleaning and detection structure also includes a guide rod 23, the two ends of which are fixedly connected to the sides of the two rotating disks 19 that are close to each other. A moving seat 24 is provided on the outer wall sliding sleeve of the guide rod 23, and the moving seat 24 is threadedly connected to the screw rod 22. The end of the moving seat 24 away from the cylinder brush 21 is fixedly connected to the second laser rangefinder 25, and the screw rod 22 drives the second laser rangefinder 25 to move through the moving seat 24 to detect the degree of wear on the surface of the roller 2; the cylinder brush 21 and the screw rod 22 are reversed, and the second laser rangefinder 25 is aimed at the roller 2 to be detected, and the first gear 26 at one end of the screw rod 22 is meshed with the second gear 27, and the roller 2 drives the screw rod 22 to rotate, and the screw rod 22 drives the moving seat 24 and the second laser rangefinder 25 to move. The second laser rangefinder 25 can detect the radial distance of the surface of the roller 2, thereby detecting the degree of wear on the surface of the roller 2, and can be easily detected without disassembling the roller 2.

[0054] Specifically, when it is necessary to detect the degree of wear of the drum 2, the drum brush 21 and the screw rod 22 are turned around so that the second laser rangefinder 25 is aimed at the drum 2. When the drum 2 rotates, the screw rod 22 is driven to rotate by the gear ring 28 and the second gear 27, thereby driving the moving seat 24 and the second laser rangefinder 25 to move, detecting the radial distance of the surface of the drum 2, thereby determining the degree of wear.

[0055] Reference Figure 7 and Fig.10 The conversion structure mainly includes a slide bar 35, a turntable 37, a second tension spring 36, a pin hole 38, a pin rod 39 and an L-shaped limit plate 40. Specifically, the slide bar 35 passes through the frame and extends to one side thereof, and a turntable 37 is fixed at its end. Two pin holes 38 are designed inside the turntable 37, and two pin rods 39 are fixed at the corresponding positions of the frame. When the pin holes 38 are engaged with the pin rods 39, the turntable 37 is braked. The other end of the slide bar 35 slides and extends to the inside of the rotating shaft 18, and a second tension spring 36 is fixed thereto, and the other end of the second tension spring 36 is fixedly connected to the inner wall of the rotating shaft 18. In addition, two L-shaped limit plates 40 are fixed to one side of the frame to limit the rotation range of the turntable 37.

[0056] Specifically, when in use, if the position of the cylinder brush 21 and the second laser rangefinder 25 needs to be adjusted, first manually pull the turntable 37 outward so that the pin hole 38 and the pin rod 39 are disengaged, thereby releasing the brake on the turntable 37. Subsequently, the turntable 37 rotates to drive the slide bar 35 and the rotating shaft 18 connected thereto to rotate 180 degrees. In this process, the presence of the second tension spring 36 ensures the smoothness of the rotation and the automaticity of the reset. After the rotation is completed, the directions of the cylinder brush 21 and the screw rod 22 are reversed, and at the same time, the second laser rangefinder 25 is aligned with the roller 2 to be detected, so that the positions of the cylinder brush 21 and the second laser rangefinder 25 are swapped to meet different cleaning and detection requirements.

[0057] The conversion structure mainly realizes the conversion between different functions (cleaning and detection) by adjusting the connection mode between the cylinder brush 21, the second laser rangefinder 25 and the corresponding driving components, thereby ensuring flexible switching between the cleaning and detection modes.

[0058] Reference Figure 3 , Figure 7 and Figure 8 The bottom inner wall of the bending collection plate 29 is designed with an inclined groove 31, which has a certain inclination angle to facilitate the discharge of materials and adhesives. At the same time, a first discharge port 32 is provided in the rotating disk 19 opposite to the bending collection plate 29, and the discharge port cooperates with the inclined groove 31 to ensure that the materials and adhesives can be discharged smoothly. In addition, a guide plate 33 is fixed to one side of the rotating disk 19, and the guide plate 33 is closely matched with the first discharge port 32 to guide the materials and adhesives to further flow to the second discharge port 34 set on one side of the frame.

[0059] Specifically, in actual operation, when the cylinder brush 21 rotates counterclockwise, the comb 30 thereon will remove the materials and adhesives on the surface of the cylinder 2. These removed materials and adhesives then fall into the bent collection plate 29 and slide toward the first discharge port 32 along the guidance of the inclined groove 31. Through the continuous action of the first discharge port 32, the guide plate 33 and the second discharge port 34, the materials and adhesives are finally discharged to the outside of the conveyor, achieving effective cleaning and discharge functions.

[0060] Reference Figure 1 , Figure 3 and Figure 4 Two round holes 10 are provided on both sides of the frame, and the design of these round holes 10 facilitates the installation and rotation of the hexagon socket bolts 9.

[0061] Specifically, one end of the hexagon socket bolt 9 passes through the mounting hole on the frame and extends into the circular hole 10. Due to the presence of the circular hole 10, when the hexagon socket bolt 9 needs to be adjusted or tightened, the corresponding tool can be used to easily operate without worrying about the interference between the tool and other parts of the frame, thereby improving the convenience and efficiency of maintenance.

[0062] Reference Figure 1 and Figure 5 A buzzer is fixedly installed on the top of the frame, and the buzzer is connected to the pressure sensor 15 through a circuit to form an electrical signal transmission path. When the pressure sensor 15 detects that the roller 2 or related parts are offset, and the offset reaches a preset threshold, the pressure sensor 15 will send an electrical signal to the buzzer, triggering the buzzer to sound an alarm. At the same time, the belt conveyor is automatically stopped through a control system (not specifically described in the specification, but a conventional technology) to prevent further damage or safety accidents.

[0063] Reference Figure 1 and Figure 5 In order to accurately control the displacement of the roller 2 and give an alarm in time, a first laser rangefinder 17 is fixedly installed on the side of the moving plate 13 close to the pressing plate 12. The first laser rangefinder 17 can measure and feedback the distance change between the pressure sensor 15 and the pressing plate 12 in real time. When it is detected that the distance change exceeds the preset safety range, it is considered that the roller 2 has a significant displacement. At this time, the first laser rangefinder 17 will send a signal to the control system, and the control system will execute the above-mentioned alarm and shutdown operations.

[0064] Through the above-mentioned specific implementation method, the belt conveyor not only has the displacement detection function, but also can automatically stop running and issue an alarm when the roller 2 is offset. At the same time, it realizes automatic cleaning and wear degree detection of the roller 2, thereby improving the operating safety and maintenance efficiency of the equipment.

[0066] refer to Fig.11 and Fig.12, improved on the basis of Example 1: two second transverse plates 44 are provided inside the frame, and the two ends of the two second transverse plates 44 are respectively fixedly connected to the mutually close sides of the two adjacent rotating disks 19 to ensure the stability of the structure. At the same time, the second transverse plate 44 is located below the bending collection plate 29 for supporting and positioning subsequent components. Two rotating shafts 41 are fixedly connected at appropriate positions of the frame, and both rotating shafts 41 are located below the second transverse plate 44. The outer wall of the rotating shaft 41 is rotatably sleeved with rolling wheels 42, which are in close contact with the conveyor belt 3. When the conveyor belt 3 is running, the friction between it and the rolling wheels 42 will drive the rolling wheels 42 to rotate synchronously. The outer wall of the rolling wheel 42 is designed with a plurality of arc grooves 43, which are designed to cooperate with the subsequent knocking rod 45 to achieve the knocking action.

[0067] refer to Fig.11 and Fig.12 In the two second horizontal plates 44, knocking rods 45 are slidably passed through, the bottom ends of these knocking rods 45 are matched with the arc grooves 43 of the rolling wheel 42, and the top ends touch the bottom of the bent collecting plate 29. In addition, the outer wall of the knocking rod 45 is also sleeved with a third tension spring 46, the top end of the third tension spring 46 is fixedly connected to the knocking rod 45, and the bottom end is fixedly connected to the top of the second horizontal plate 44. In this way, when the rolling wheel 42 rotates, its arc groove 43 will drive the knocking rod 45 to move up and down under the action of the third tension spring 46, thereby knocking the bent collecting plate 29.

[0068] Specifically, as the conveyor belt 3 continues to run, the friction between it and the rolling wheel 42 continuously drives the rolling wheel 42 to rotate. The rotation of the rolling wheel 42, through the cooperation between the arc groove 43 and the knocking rod 45, and the elastic force of the third tension spring 46, causes the knocking rod 45 to continuously knock up and down the bending collection plate 29. This knocking action helps to discharge the materials and adhesives accumulated in the bending collection plate 29 to the outside along the inclined groove 31 thereon, thereby effectively preventing these materials and adhesives from falling onto the conveyor belt 3 when the rotating shaft 18 and the rotating disk 19 rotate in the later stage, ensuring the cleanliness and efficient operation of the belt conveyor.

[0069] A method for using a belt conveyor with a displacement detection function comprises the following steps:

[0070] S1, the driving motor 4 drives one of the rollers 2 to rotate, and the two rollers 2 are connected by the conveyor belt 3. The roller 2 and the conveyor belt 3 start to run counterclockwise to transport coal, and when the roller 2 rotates, the gear ring 28, the second gear 27 and the first gear 26 cooperate to drive the rotating rod 20 and the barrel brush 21 to rotate counterclockwise. Therefore, when the roller 2 and the barrel brush 21 rotate counterclockwise synchronously, the barrel brush 21 can remove the materials and adhesives attached to the outer wall of the roller 2, keep the surface of the roller 2 clean and smooth, and avoid the outer wall of the roller 2 being affected by the materials and adhesives and causing the deviation phenomenon. In addition, when the barrel brush 21 rotates counterclockwise, the comb 30 can remove the materials and adhesives on it, and the removed materials and adhesives fall into the bending collection plate 29. Under the action of the inclined groove 31, the materials and adhesives are discharged to the outside through the first discharge port 32, the guide plate 33 and the second discharge port 34;

[0071] S2. When the roller 2 deviates during the rotation process, the end face of the roller 2 pushes the U-shaped plate 6 to move through the ball 7, and the U-shaped plate 6 pushes the moving plate 13 and the pressure sensor 15 to move through the push rod 16 until the pressure sensor 15 squeezes the pressing plate 12. At this time, the pressure sensor 15 transmits a signal to the control system, the driving motor 4 stops running, and the buzzer warns, which is convenient for the staff to carry out maintenance later; in addition, the pressing plate 12 is driven to move by rotating the hexagon socket bolt 9, and the distance between the pressure sensor 15 and the pressing plate 12 is detected by the first laser rangefinder 17, so that the distance between the pressing plate 12 and the pressure sensor 15 can be adjusted to control the roller 2 to alarm and stop running after deviating from the specified distance;

[0072] S3. When it is necessary to detect the degree of wear on the surface of the roller 2, the slide bar 35 is pulled outward through the turntable 37, the pin hole 38 and the pin bar 39 are disengaged, the brake on the turntable 37 is released, and the rotating shaft 18 is driven to rotate 180 degrees through the turntable 37 and the slide bar 35. At this time, the drum brush 21 and the screw rod 22 can be reversed, and the second laser rangefinder 25 is aimed at the roller 2 to be detected. The first gear 26 at one end of the screw rod 22 is meshed with the second gear 27. Then the driving motor 4 drives the roller 2 to rotate slowly, and the roller 2 drives the screw rod 22 to rotate. The screw rod 22 drives the moving seat 24 and the second laser rangefinder 25 to move. The second laser rangefinder 25 can detect the radial distance of the surface of the roller 2, thereby detecting the degree of wear on the surface of the roller 2. The detection can be easily performed without disassembling the roller 2.

[0073] S4. In addition, when the roller 2 and the conveyor belt 3 cooperate to transport coal, the friction between the conveyor belt 3 and the rolling wheel 42 drives the rolling wheel 42 to rotate, and the knocking rod 45 drives the knocking rod 45 to move back and forth up and down under the cooperation of the third tension spring 46, the arc groove 43 and the rolling wheel 42, so as to knock the bent collection plate 29, so that the materials and adhesives in the bent collection plate 29 are discharged to the outside along the inclined groove 31, so as to prevent the materials and adhesives from falling onto the conveyor belt 3 when the rotating shaft 18 and the rotating disk 19 rotate later.

[0074] However, as is well known to those skilled in the art, the working principles and wiring methods of the second laser rangefinder 25, the first laser rangefinder 17, the pressure sensor 15 and the drive motor 4 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0075] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
