Description

Technical Field

[0001] The utility model relates to the technical field of mine conveyor belts, and specifically relates to a monitoring and deviation correcting frame for mine conveyor belts. Background Technique

[0002] The belt conveyor for coal mines mainly refers to the belt conveyor used in the processes of coal mining, production, transportation, and processing. The belt conveyor for coal mines has the characteristics of large transportation volume, complex working environment, strong bearing capacity, and long transportation distance. It is widely used in the main coal-producing areas of China, such as Shanxi, Inner Mongolia, Xinjiang, Shandong, etc. The belt conveyor for coal mines can not only be used in the process of coal production and processing, but also be applicable to the production and processing processes of other minerals. In terms of energy consumption, it can effectively reduce energy consumption and provide economic benefits, and can save more energy and protect the environment compared with the automobile transportation method.

[0003] During the use of the mine conveyor belt, the belt deviation may be caused by various factors such as inaccurate installation of the belt conveyor, inflexible operation, material impact, load change, uneven elongation rate of the belt cross-section, etc. After the belt deviates, in order to ensure the safety and stability of transportation, the machine usually needs to be stopped for calibration, which affects the normal operation and working efficiency of the equipment. In order to improve the transportation stability of the conveyor belt, for this reason, we propose a monitoring and deviation correcting frame for mine conveyor belts. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a monitoring and deviation correcting frame for mine conveyor belts, which solves the problems raised in the above background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A monitoring and deviation correcting frame for mine conveyor belts includes an outer frame. Two support blocks are installed on the upper surface of the outer frame. A fixed support wheel is supported inside the two support blocks. The upper and lower surfaces of the inner cavity of the outer frame are fixedly installed with limit rods. A slider is movably sleeved inside the limit rods. A servo motor is fixedly installed on the upper surface of the lower slider. The top end of the output shaft of the servo motor is fixedly connected with a threaded column. A ball screw block is movably sleeved outside the threaded column. An active block is fixedly connected to the outside of the ball screw block. An active support wheel is movably supported between the active block and the support block.

[0006] Optionally, a color sensor is fixedly installed above the inner bottom surface of the outer frame. A conveyor belt is supported on the upper surfaces of the fixed support wheel and the active support wheel. An induction color strip is coated on the middle part of the bottom surface of the conveyor belt.

[0007] Optionally, the fixed support wheel is located near the middle position at the bottom of the inner cavity of the outer frame, and the outer height value of the active support wheel is greater than the middle height value.

[0009] Optionally, the induction color strip is located above the three color sensors, and the three color sensors are located at the middle position inside the outer frame.

[0010] The utility model provides a monitoring and deviation-correcting frame for a mine conveyor belt, which has the following beneficial effects:

[0011] 1. For this monitoring and deviation-correcting frame of the mine conveyor belt, through the setting of the outer frame, a fixed support wheel is supported inside the outer frame by a support block, and at the same time, a limiting rod is arranged inside the outer frame. The limiting rod can be used to limit the movement track of the slider. A servo motor and a threaded post are arranged between the two sliders, which can control the position of the ball screw block, and then respectively control the inclination of the two movable support wheels, so as to facilitate the deviation correction of the belt and the use of the equipment.

[0012] 2. For this monitoring and deviation-correcting frame of the mine conveyor belt, by supporting a color sensor inside the outer frame, the fixed support wheel and the movable support wheel support the conveyor belt above, and an induction color strip is coated on the bottom surface of the conveyor belt and is located above the three color sensors.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a monitoring and deviation-correcting frame for a mine conveyor belt, including an outer frame 1. Two support blocks 2 are installed on the upper surface of the outer frame 1. A fixed support wheel 3 is supported inside the two support blocks 2. The fixed support wheel 3 is located near the middle position at the bottom of the inner cavity of the outer frame 1. The height value of the outer side of the movable support wheel 4 is greater than the height value of the middle part. The cooperation of the fixed support wheel 3 and the movable support wheel 4 can support the conveyor belt 12, thereby facilitating the transportation of coal blocks. At the same time, the fixed support wheel 3 in the middle mainly plays a supporting role, while the setting of the movable support wheel 4 plays a role in cooperating to control and correct the deviation of the belt, and can conveniently complete the correction of the belt during the transportation process of the belt. The upper and lower surfaces of the inner cavity of the outer frame 1 are fixedly installed with limit rods 5. A slider 6 is movably sleeved inside the inner side of the limit rod 5. The top end of the threaded column 8 is movably sleeved inside the upper slider 6. The vertical cross-section of the outer frame 1 is U-shaped. The setting of the limit rod 5 plays a role in restricting the movement of the slider 6. Using the cooperation of the limit rod 5 and the slider 6, the position of the ball screw block 9 can be adapted. When the ball screw block 9 is close to the upper part, the ball screw block 9 will be close to the middle of the outer frame 1, and when the ball screw block 9 is close to the lower part, the ball screw block 9 will be close to the outer side of the outer frame 1. A servo motor 7 is fixedly installed on the upper surface of the lower slider 6. The top end of the output shaft of the servo motor 7 is fixedly connected to a threaded column 8. A ball screw block 9 is movably sleeved outside the threaded column 8. The outer side of the ball screw block 9 is fixedly connected to a movable block 10. A movable support wheel 4 is movably supported between the movable block 10 and the support block 2. For the angles of the two movable support wheels 4, the output shaft of the servo motor 7 in the offset direction drives the threaded column 8 to rotate. During the rotation of the threaded column 8, the ball screw block 9 outside the threaded column 8 moves upward. The ball screw block 9 will drive the upper part of the movable support wheel 4 to rise, increasing the angle between the movable support wheel 4 and the horizontal plane, and decreasing the angle between the other movable support wheel 4 and the horizontal plane, and then slowly guiding the belt to reset.

[0020] A color sensor 11 is fixedly installed above the inner bottom surface of the outer frame 1. The fixed support wheel 3 and the movable support wheel 4 support a conveyor belt 12. An induction color strip 13 is coated on the middle part of the bottom surface of the conveyor belt 12. After the conveyor belt 12 is offset, the induction color strip 13 below the conveyor belt 12 will move to the outside above the color sensor 11. One of the two color sensors 11 will no longer be able to sense the induction color strip 13, and then the offset direction of the conveyor belt 12 can be judged, and then the deviation correction is completed by cooperating with the movable support wheel 4. The induction color strip 13 is located above the three color sensors 11, and the three color sensors 11 are located at the middle position inside the outer frame 1.

[0021] In summary, for the mine conveyor belt monitoring and deviation correction frame, during use, first, during the conveying process, the cooperation of the fixed support wheel 3 and the movable support wheel 4 will support the conveyor belt 12. When the conveyor belt 12 runs off track under the impact of materials, load changes, etc. during the continuous conveying of coal blocks, first, the induction color strip 13 below the conveyor belt 12 will move to the outside above the color sensor 11. One of the two color sensors 11 will no longer be able to sense the induction color strip 13. Subsequently, the deviation direction of the conveyor belt 12 can be judged, and then the angles of the two movable support wheels 4 are controlled. The output shaft of the servo motor 7 in the deviation direction drives the threaded column 8 to rotate. During the rotation of the threaded column 8, the ball screw block 9 outside the threaded column 8 moves upward. The ball screw block 9 drives the upper part of the movable support wheel 4 to rise, increasing the angle between the movable support wheel 4 and the horizontal plane, and decreasing the angle between the other movable support wheel 4 and the horizontal plane. Then, the belt is slowly guided back to its original position, and that's it.
