Description

Technical Field

[0001] The present invention relates to the technical field of intelligent control of conveyors, and particularly to an integrated intelligent control device for a belt conveyor in a tunneling working face. Background Art

[0002] With the continuous innovation of microelectronics, computer and automation technologies, high-efficiency mechatronics technologies and their supporting equipment have been widely applied in the coal industry. This trend has profoundly changed the traditional operation mode of coal production and significantly improved the equipment performance and automation level of fully mechanized mining faces. Among them, the integrated intelligent control device for a belt conveyor in a tunneling working face is a device that is applied to the tunneling working area of coal mines and other mineral mining areas to comprehensively and intelligently control the belt conveyor. It integrates a variety of advanced technologies to improve the automation and intelligent level of the operation of the belt conveyor and ensure the efficient and safe transportation of materials. However, the inventor found in long-term market research that there are still some key problems with the current integrated intelligent control device for a belt conveyor in a working face, which are mainly reflected in the following aspects: First of all, the uniformity of the material distribution on the conveyor belt has a great impact on its running stability. When the material is concentrated on one side of the conveyor belt, it will cause uneven forces on both sides of the conveyor belt, resulting in deviation. Especially in coal mining, when the loading equipment unloads materials onto the conveyor belt, the position is inaccurate, causing the material to deviate to one side, and the conveyor belt is prone to deviate to the side with more materials during operation; Secondly, the environment in the mine tunnel is complex, with a lot of coal powder and dust. These dusts are extremely easy to adhere to the transmission wheels at both ends of the conveyor belt, resulting in uneven surfaces of the transmission wheels and inability to closely fit with the conveyor belt, thus causing the conveyor belt to deviate; Finally, when the material flow rate changes, the control device cannot accurately adjust the conveyor belt speed, resulting in unstable material transportation, and there may be phenomena such as accumulation or idling, affecting the transportation efficiency; This patent mainly avoids the occurrence of the conveyor belt deviation phenomenon and improves its working efficiency by automatically cleaning the dust on the surface of the transmission wheels and spreading the material particles on the surface of the conveyor belt.

[0018] The following further describes the specific embodiments of the present invention in conjunction with the drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention.

[0019] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] Embodiment 1, referring to Figures 1 to 7 , which is the first embodiment of the present invention. This embodiment provides an integrated intelligent control device for a belt conveyor in a tunneling working face, which has the effects of cleaning the dust on the surface of the transmission component 7, strengthening the friction between the transmission component 7 and the conveyor component 1, and preventing the conveyor component 1 from deviating. It includes a conveyor and a controller 11. The conveyor includes a conveyor component 1, a machine board 2, a support component 3, and a driving component 4. The conveyor component 1 is arranged between two machine boards 2, and the support component 3 and the driving component 4 are both arranged on the side walls of the machine board 2; Specifically, the driving component 4 includes a photoelectric speed sensor 401, a servo motor 402 and a gear reducer 403. The sensing end of the photoelectric speed sensor 401 is arranged at the output end of the gear reducer 403. The servo motor 402 and the gear reducer 403 are both fixedly mounted on the side wall of the machine plate 2 by bolts. The input end of the gear reducer 403 is fixedly mounted with the output end of the servo motor 402. The output end of the gear reducer 403 passes through the side wall of the machine plate 2 and is fixedly mounted with a mounting shaft 5. The other end of the mounting shaft 5 is fixedly mounted with a transmission component 7 via a coupling 6. The conveying component 1 is connected to the transmission component 7 in a transmission manner. The gear reducer 403 is a planetary gear reducer. The gear reducer 403 ensures the normal operation of the transmission component 7 by providing stable and reliable power transmission. The gear reducer 403 has high-precision transmission and speed regulation functions to meet the control requirements of the controller 11 for the conveyor. Further, the transmission assembly 7 includes a shaft installer 701, a transmission roller 702 and a mounting block 703. The transmission roller 702 is rotatably installed between the two machine plates 2. There are two shaft installers 701 that are symmetrically fixedly installed at the centers of both ends of the transmission roller 702. One end of the shaft installer 701 that is away from the transmission roller 702 is fixedly installed with the mounting shaft 5. There are multiple mounting blocks 703 and they are arranged in a ring on the transmission roller 702. The transmission roller 702 is provided with multiple mounting grooves 71 that match the mounting blocks 703 in a ring. The mounting blocks 703 are slidably connected in the mounting grooves 71. A piston 705 is fixedly installed at the bottom of the mounting block 703. The piston 705 is sealingly slidably connected in the mounting groove 71. Among them, by providing the mounting groove 71, the spring 706 and the mounting block 703, when the mounting block 703 is retracted into the mounting groove 71 under the pressure of the conveying assembly 1, the spring 706 is squeezed, and the elastic force generated by the spring 706 makes the end of the mounting block 703 abut against the inner wall of the conveyor belt 101, thereby increasing the friction between the transmission roller 702 and the conveying assembly 1 in disguised form, reducing the probability of the transmission roller 702 running off, and the installation groove 71 is provided on the transmission roller 702 so that the conveying assembly 1 can better adapt to the volume change caused by thermal expansion and contraction caused by temperature changes in the mine cave; An exhaust passage 704 is provided in the mounting block 703. The exhaust passage 704 is in a barb shape and its bottom end penetrates through the bottom of the piston 705 and communicates with the mounting groove 71. A one-way air outlet valve 705b is fixedly installed in the exhaust passage 704. A one-way air inlet valve 705a is fixedly installed in the piston 705. The upper end of the one-way air inlet valve 705a is communicated with the outside world, and the lower end of the one-way air inlet valve 705a is communicated with the mounting groove 71. A spring 706 is fixedly installed at the lower end of the piston 705, and the other end of the spring 706 is fixedly installed at the bottom of the mounting groove 71. Among them, by setting the one-way intake valve 705a, when the mounting block 703 disengages from the contact with the conveying component 1 from above, the mounting block 703 moves in the direction away from the spring 706 to reset under the action of the spring 706. At this time, the outside air enters the mounting groove 71 through the one-way intake valve 705a. Then, when the mounting block 703 contacts the conveying component 1 below, under the extrusion of the conveying component 1, the mounting block 703 retracts into the mounting groove 71 again. At this time, the air pressure in the sealed space formed between the mounting groove 71 and the piston 705 increases. Finally, the air in the mounting groove 71 enters the exhaust passage 704 through the one-way exhaust valve 705b and is ejected from the other port of the exhaust passage 704 to blow and wash the dust on the surface of the driving roller 702. Because the exhaust passage 704 is smaller than the space volume of the mounting groove 71, the air flow velocity accelerates when the air enters the exhaust passage 704 from the mounting groove 71, so that the gas ejected from the exhaust passage 704 impacts the dust attached to the surface of the driving roller 702, making the dust attached to the surface of the driving roller 702 easier to fall off; Specifically, because the exhaust passage 704 is divided into a longitudinal passage 704b and a transverse passage 704a, and the included angle between the transverse passage 704a and the longitudinal passage 704b is 60°, the gas ejected from the transverse passage 704a just corresponds to the surface of the driving roller 702 between two adjacent mounting blocks 703. Moreover, the gas ejected from the exhaust passage 704 instantaneously increases the pressure between two adjacent mounting blocks 703, and the air flow flows to both sides of the moving direction of the conveying component 1 to take away the fallen dust and prevent it from falling on the inner wall of the conveying component 1; In the basic logic and concept expressed above, the conveyor provided by the present invention is significantly different from the existing conveyors, which is manifested as follows: First, the surfaces of the driving rollers 702 in the existing conveyors are all smooth, and only rely on the friction force generated by the wrap angle formed by the driving rollers 702 and the conveyor belt 101 to drive the conveyor belt 101 to rotate. In this way, when dust adheres to the surface of the conveyor belt 101, it is easy to cause slippage and lead to the deviation of the conveyor belt 101. In the present invention, by providing mounting grooves 71 on the driving rollers 702 and arranging mounting blocks 703 and pistons 705 in the mounting grooves 71, the effect of automatically cleaning the dust on the surface of the driving rollers 702 is achieved. Moreover, the surface of the driving roller 702 is divided into multiple cleaning intervals by the mounting blocks 703. Then, through the change of the air pressure inside each mounting block 703, the air flow ejected from the exhaust passage 704 can clean the dust attached to the surface of the driving roller 702 in the corresponding interval, with obvious effect, and avoid the deviation of the conveyor belt 101 caused by the dust adhering to the surface of the driving roller 702; Second, by making the mounting blocks 703 fit with the strip-shaped grooves 102 on the inner side of the conveyor belt 101, the friction force between the transmission component 7 and the conveying component 1 is increased, and further the tightness of the connection between the transmission component 7 and the conveying component 1 is improved; Thirdly, the exhaust passage 704 is divided into a longitudinal passage 704b and a transverse passage 704a, and the included angle between the transverse passage 704a and the longitudinal passage 704b is 60°. Therefore, the gas ejected from the transverse passage 704a just corresponds to the surface of the transmission roller 702 between two adjacent mounting blocks 703, improving the cleaning effect. Moreover, the gas ejected from the exhaust passage 704 instantaneously increases the pressure between two adjacent mounting blocks 703, and the air flows to both sides of the moving direction of the conveying assembly 1, taking away the fallen dust and preventing it from falling on the inner wall of the conveying assembly 1; Further illustrate the working mode and advantages of the device in combination with the prior art: Start the servo motor 402 to drive the photoelectric speed sensor 401 to work. The photoelectric speed sensor 401 drives the mounting shaft 5 to rotate, and then drives the transmission assembly 7 to rotate, realizing the transportation of coal mines. During the rotation of the transmission assembly 7, when the mounting block 703 disengages from the contact with the conveying assembly 1 from above, the mounting block 703 moves in the direction away from the spring 706 to reset under the action of the spring 706. At this time, the outside air enters the mounting groove 71 through the one-way intake valve 705a. Then, when the mounting block 703 contacts the lower conveying assembly 1, under the extrusion of the conveying assembly 1, the mounting block 703 retracts into the mounting groove 71 again. At this time, the air pressure in the closed space formed between the mounting groove 71 and the piston 705 increases. Finally, the air in the mounting groove 71 enters the exhaust passage 704 through the one-way exhaust valve 705b and is ejected from the other port of the exhaust passage 704 to blow and wash the dust on the surface of the transmission roller 702. Because the exhaust passage 704 is smaller than the space volume of the mounting groove 71, the air flow speed accelerates when the air enters the exhaust passage 704 from the mounting groove 71, so that the gas ejected from the exhaust passage 704 impacts the dust attached to the surface of the transmission roller 702, making the dust attached to the surface of the transmission roller 702 easier to fall off.

[0021] Therefore, the present invention adopts a completely different transmission method from the prior art. By arranging the mounting block 703, the piston 705 and the spring 706 on the transmission roller 702, it can directly skip the high-complexity and high-cost cleaning methods such as manual cleaning and blower cleaning in the prior art with low-difficulty and low-cost technical means, solving the problem of "the environment in the mine tunnel is complex, there are a lot of coal powder and dust, and the dust is extremely easy to adhere to the transmission wheels at both ends of the conveyor belt, resulting in the uneven surface of the transmission wheels and the inability to fit tightly with the conveyor belt, thus causing the conveyor belt to deviate". It effectively solves the problem of the high use and maintenance cost of the conveyor in the prior art.

[0022] Example 2, refer to Figures 7 to 12, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an adjustment component 10, which realizes the effect of evenly spreading the material on the conveying component 1 in a limited space of a mine cave. Compared with the prior art, under the same effect, the present invention has the advantages of simple manufacturing process, very low cost and stable and reliable effect. It includes an adjustment component 10 arranged above the conveyor, and the adjustment component 10 includes two mounting plates 1003, two adjustment plates 1002 and two electric telescopic rods 1004. The two mounting plates 1003 are symmetrically fixed on both sides. On the machine plate 2, two adjustment plates 1002 are symmetrically rotatably mounted on the mounting plate 1003 through the rotating shaft 1001, and a first mounting ear 1005 is fixedly mounted on the side wall of each mounting plate 1003, and a first connecting shaft 1006 is vertically rotatably mounted on each first mounting ear 1005, and the lower end of the first connecting shaft 1006 is fixedly mounted on the electric telescopic rod 1004, and the telescopic end of the electric telescopic rod 1004 is rotatably connected to the second mounting ear 1007 through the second connecting shaft 1008, and the second mounting ear 1007 is fixedly mounted on the inner wall of the adjustment plate 1002; The electric telescopic rod 1004 pushes the adjustment plate 1002 to rotate through the telescopic end, flattening the material transported on the surface of the conveying component 1, thereby avoiding the material being concentrated on one side of the conveyor belt, which would cause unbalanced force on both sides of the conveyor belt and cause deviation; Specifically, the angle between the mounting plate 1003 and the adjustment plate 1002 is β, and the mounting plate 1003 is also provided with an angle sensor corresponding to the angle β, and the adjustment plate 1002 includes an L-shaped rectangular trough 1002c, and a stepper motor 1002d is fixedly installed on the upper end surface of the L-shaped rectangular trough 1002c, and two rollers 1002a are symmetrically rotatably installed on the inner wall of the L-shaped rectangular trough 1002c, one of the rollers 1002a is fixedly installed at the output end of the stepper motor 1002d, and the two rollers 1002a are connected by a transmission belt 1002b; Among them, when the material on the conveying component 1 is transported from left to right, when the material on the surface of the conveying component 1 that is higher than the horizontal plane of the upper end surface of the machine plate 2 collides with the adjustment plate 1002, part of the material is distributed to the low-lying areas on both sides, and part of the material is gathered to the middle along the inclined surface of the adjustment plate 1002 to prevent the conveying component 1 from deviating due to the different weights of the materials on both sides. When the output of the mining machine at the source is large, the transportation burden of the conveying component 1 increases. At this time, the pressure sensor on the auxiliary steel frame 8 close to one end of the mining machine sends a boost signal to the controller 11. After receiving the signal, U1 in the controller 11 collects the speed V1 of the output end of the gear reducer 403 through the photoelectric speed sensor 401, and then learns that the transmission speed of the conveying component 1 is also V1. After being processed by U1, a start signal is sent to the stepper motor 1002d, and the output speed V2 of the stepper motor 1002d is adjusted in real time. Among them, , it avoids the accumulation of materials on the conveyor belt 1002b, spreads the materials on the surface of the conveying component 1 more quickly, and solves the problem that "when the materials are concentrated on one side of the conveyor belt, the forces on both sides of the conveyor belt will be unbalanced, resulting in deviation. Especially in coal mining, when the loading equipment unloads materials onto the conveyor belt, the position is inaccurate, causing the materials to deviate to one side, and the conveyor belt is prone to deviate to the side with more materials during operation"; A temperature sensor, a camera and an alarm are also arranged on the side wall of the machine board 2, and a pressure sensor is arranged on the auxiliary steel frame 8. The temperature sensor, the pressure sensor, the angle sensor, the camera and the photoelectric rotational speed sensor 401 are all connected to the signal output end of the conveying component 1 through radio, and the signal output end of the controller 11 is connected to the servo motor 402 and the electric telescopic rod 1004 through radio respectively. The conveying component 1 is internally provided with a control chip U1, and the control chip U1 is a programmable controller chip. The conveying component 1 is installed at the end of the conveyor or at any position within the radio communication range. The controller 11 can understand the operation of the conveyor in the mine tunnel in real time through the temperature sensor, the pressure sensor, the angle sensor, the camera and the photoelectric rotational speed sensor 401, and make corresponding adjustments by wirelessly controlling the electric telescopic rod 1004 and the servo motor 402. When an emergency occurs, the controller 11 controls the alarm to give an alarm, solving the problem that "when the material flow changes, the control device cannot accurately adjust the conveyor belt speed, resulting in unstable material conveying, and there may be accumulation or idling phenomena, affecting the conveying efficiency"; The supporting component 3 includes a movable support 301 and a fixed support 302. The upper ends of the movable support 301 and the fixed support 302 are both fixedly installed on the side wall of the machine board 2 through bolts, facilitating the movement and parking of the conveyor; A plurality of auxiliary steel frames 8 are fixedly installed at equal intervals between the two machine boards 2. The upper end surface of the auxiliary steel frame 8 is attached to the inner wall of the conveying component 1, providing a supporting force for the conveying component 1 to prevent the conveying component 1 from being damaged due to excessive pressure; An adjusting roller 9 is also arranged between the two machine boards 2. The adjusting roller 9 is slidably connected to the lower side wall of the conveyor belt 101. By arranging the adjusting roller 9, the tension of the conveying component 1 can be adjusted; The special feature of this device lies in the cooperation between the controller 11, the temperature sensor, the pressure sensor, the photoelectric rotational speed sensor, the angle sensor, the camera, the electric telescopic rod 1004 and the servo motor 402: First, one of the highlights of this device is that the controller 11 can understand the operation of the conveyor in the mine tunnel in real time through the temperature sensor, the pressure sensor, the angle sensor, the camera and the photoelectric rotational speed sensor 401, and make corresponding adjustments by wirelessly controlling the electric telescopic rod 1004 and the servo motor 402. When an emergency occurs, the controller 11 controls the alarm to give an alarm; Second, after U1 in the controller 11 receives the signal, it collects the rotational speed V1 at the output end of the gear reducer 403 through the photoelectric rotational speed sensor 401, and then knows that the transmission speed of the conveying component 1 is also V1. After being processed by U1, a start signal is sent to the stepping motor 1002d, and the output rotational speed V2 of the stepping motor 1002d is adjusted in real time, where , it avoids the accumulation of materials on the conveyor belt 1002b and spreads the materials on the surface of the conveying component 1 more quickly; The remaining structures are the same as those in Embodiment 1.

[0023] Combining Embodiment 1 and Embodiment 2, the structural design of the device, by deploying high-precision sensors and cameras, ensures real-time data monitoring and display throughout the production process, reduces the probability of the conveyor running off track, and reduces production costs, thus enhancing economic benefits.
