Description
TECHNICAL FIELD
[0001] The utility model relates to the field of coal mining, especially a long distance coal flow system belt deviation detection device. BACKGROUND
[0002] The coal flow conveying system formed by coal mining is mainly divided into mine roadway conveying system and surface conveying system according to the geological conditions of the mining area. The long distance coal flow system (conveying distance is greater than or equal to 200 meters) has the following characteristics: large spatial span, the length of the main transport belt of the open pit mine can reach 3-5 kilometers; significant terrain undulation, the vertical height difference of the mine conveying line often exceeds 150 meters; high environmental complexity, the working scene contains high dust concentration and humidity, so high requirements are put forward for the mine roadway conveying system. In the process of coal mining, the crushed coal blocks are conveyed outward through the belt of the coal feeder, but the belt of the coal feeder is easy to deviate from the normal position due to uneven belt tension, improper installation, equipment failure, unbalanced load, belt wear, external factors such as uneven feeding of the coal bunker, etc., thereby affecting the running efficiency and safety of the system, so a belt deviation detection device is generally provided in the coal feeder. The belt deviation detection device is used to prevent the belt deviation from causing uneven material conveying, equipment damage or coal flow blockage, and ensure the safe and stable operation of the equipment.
[0003] A coal feeder belt deviation detection device is disclosed in the utility model with the publication number CN220282615U. The device can detect the conveying position of the conveyor belt with different widths through the setting of the screw rod and the sliding groove mechanism. However, when using the device, due to the structure of the device, it can only be applied to some small and short distance coal feeders. When it is used in some coal flow systems with a distance of more than 100 meters, the signal may be weakened due to the long distance, affecting the detection effect of the belt deviation. At the same time, some long distance coal flow systems are set in a fluctuating state due to the terrain, so the above belt deviation detection device cannot maintain the signal stability in the long coal flow system.
[0004] Therefore, the utility model provides a long distance coal flow system belt deviation detection device to solve the above problems of the prior art. UTILITY MODEL CONTENTS

[0037] In the above description, before installing the detection device, the staff first needs to count the nodes of the long distance coal flow system in straight flow, deflection and height fluctuation, so as to determine the installation position of the detection device, then according to the distance that the signal transmitter 2 and the signal receiver 4 can keep stable signal receiving, the installation is debugged, if it is straight flow, then only the signal transmitter 2 and the signal receiver 4 need to be installed according to the specified distance, if it is the case of height fluctuation, then the staff can use the adjusting assembly 3 to debug the position and angle of the signal transmitter 2 and the signal receiver 4 to adapt to the belt in different states, so as to realize the real-time detection of the signal transmitter 2 and the signal receiver 4 to the belt of the long distance coal flow system in different states, so as to ensure the detection accuracy.
[0038] It should be noted that the device is installed along the length direction of the belt, that is, the installation of the signal transmitter 2 and the receiver 4 needs to follow the principle of "three-point positioning" to ensure that the detection system can cover the key area of the belt operation and adapt to complex terrain and harsh environment. At the same time, the belt deviation detection device is installed on both sides of the belt to be detected, and the distance from the edge of the belt is 50-100mm (adjusted dynamically according to the width of the belt).

[0044] In the above description, the threaded sleeve 311 is symmetrically arranged at the rear end of the adjusting plate 31, when encountering a belt with fluctuating height, the workers can drive the screw rod 37 to make the threaded sleeve drive the adjusting plate 31 to rise or move downward, so that the signal transmitter 2 or the signal receiver 4 can be adapted to belts with different heights, and the stability and accuracy of signal transmission and reception are ensured.
[0045] In a preferred embodiment, as shown in Figure 2 and Figure 3 , in order to match the detection of the offset of the adjacent conveying belt of the coal flow system at the same time, the adjusting plate 31 is arranged on the side of the connecting plate 1 close to the belt 5, and a recess 39 is arranged on the side of any adjusting plate 31 close to the other adjusting plate 31, and a protruding part is arranged on the side of the other adjusting plate 31 close to the recess 39, the recess 39 and the protruding part are matched to ensure the fitting between the adjacent adjusting plates 31 during the detection of the adjacent conveying belt of the coal flow system at the same time.

[0047] In the above description, the center of the arc-shaped hole 32 and the rotating shaft point of the adjusting plate 33 are on the same axis.
[0048] When encountering a highly undulating belt and being in a tilted situation, the personnel need to respectively place the signal receiver 4 and the signal transmitter 2 at the end of the belt at the tilted position, then the worker twists the second nut 38, so that the second adjusting screw rod 36 slides in the arc-shaped hole 32 and adjusts the angle of the adjusting plate 33, and makes the signal transmitter 2 and the signal receiver 4 be at the same level with the belt, and then the second nut 38 is tightened.
[0049] Working principle: in specific use, first, the worker needs to count the nodes of straight flow, flow deflection and height undulation of the long-distance coal flow system, then debug and install according to the distance that the signal transmitter 2 and the signal receiver 4 can keep stable signal receiving, if it is straight flow during debugging, then only the signal transmitter 2 and the signal receiver 4 need to be installed according to the specified distance, if it is the height undulation situation, then the worker can first twist the second nut 38, then make the second adjusting screw rod 36 slide in the arc-shaped hole 32 and make the signal transmitter 2 and the signal receiver 4 be at the same level with the belt, and then tighten the second nut 38, at the same time, the worker can also adjust the position of the signal transmitter 2 or the signal receiver 4 by twisting the lead screw 37 to make the threaded sleeve drive the adjusting plate 31 to rise or move down to adapt to the belt of different heights, when encountering some belts of different widths, the worker only needs to loosen the first nut 34, then drive the signal transmitter 2 or the signal receiver 4 by the first adjusting screw rod 35 in the slot hole of the adjusting plate 33 to debug the position of the signal transmitter 2 or the signal receiver 4 according to the width of the belt, finally, tighten the first nut 34 and fix the position of the first adjusting screw rod 35, in this way, the signal transmitter 2 and the signal receiver 4 can be suitable for precise detection of various forms of belts in the long-distance coal flow system.
