[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] A belt deviation monitoring device, such as Figure 1-Figure 3 As shown, it includes a rack 1 and a mounting frame 2 that provide an installation base, wherein the mounting frame 2 is fixed to the rack 1 by screws, and a hollow shell inside the mounting frame 2 has monitoring windows 3 on the left and right sides of the mounting frame 2. An axial monitoring component that can slide left and right in the monitoring window 3 is movably installed in the monitoring window 3. When the deviation of the tape is monitored, the deviated tape contacts the monitoring component, causing the monitoring component to slide left and right in the mounting frame 2 to generate displacement, thereby triggering an alarm.
[0025] In order to reduce the rust and dust wear caused by coal mines and outdoor use, which makes the monitoring component unable to slide smoothly left and right, the inner edge of the monitoring window 3 does not contact the monitoring component. In this embodiment, the monitoring window 3 is a rectangular groove and the width is 1.5 times the diameter of the monitoring component. At the same time, the mounting frame 2 is provided with a limiting portion in the shell away from the frame 1 and in the middle position. The limiting portion is composed of two vertical groups of vertical limiting rods 4 and two horizontal groups of horizontal limiting rods 5, wherein the ends of the vertical limiting rods 4 and the horizontal limiting rods 5 are provided with external threads 6, and the vertical limiting rods 4 and the horizontal limiting rods 5 are connected to the external threads 6 of the mounting frame 2 through the external threads 6. Adjacent vertical limiting rods 4 and horizontal limiting rods 5 are staggered around the monitoring component to fix the monitoring component. The monitoring component fixed in this way is fixed by four points, reducing the influence of rust and resistance on monitoring accuracy.
[0026] Furthermore, the contact positions of the vertical limiting rod 4 and the horizontal limiting rod 5 with the monitoring component can be changed by rotating the vertical limiting rod 4 and the horizontal limiting rod 5, without worrying about the fixed point being worn, and maintenance is simpler.
[0027] In other embodiments, to facilitate observation and adjustment of the monitoring assembly, the side wall of the mounting frame 2 is open and fixedly mounted with a side panel 7 , and two sets of vertical limit rods 4 located in the middle of the mounting frame 2 are threadedly connected to the side panel 7 .
[0028] In another embodiment, the monitoring window 3 is a triangle, and 4 and 5 form a triangle surrounding the monitoring component. That is, 4 and 5 can form a variety of shapes as long as the monitoring component can be limited in the up and down and front and back directions.
[0029] Among them, the monitoring component includes a central axis 8, a pressure sensor 9 and a probe 10. The central axis 8 crosses the left and right groups of mounting frames 2. The vertical limit rod 4 and the horizontal limit rod 5 are in contact with the central axis 8. The pressure sensor 9 and the probe 10 are respectively fixed on both sides of the central axis 8. The pressure sensor 9 is fitted with the left side of the mounting frame 2, and the probe 10 passes through the frame 1 and contacts the tape. When the tape deviates and touches the probe 10, it pushes the pressure sensor 9 away from the mounting frame 2, thereby changing the pressure at the input end of the pressure sensor 9, that is, the tape deviation is monitored.
[0030] Furthermore, a middle plate 11 is fixedly installed in the middle of the central shaft 8, and a spring 12 is fixedly installed on the end face of the middle plate 11 close to the pressure sensor 9. The other end of the spring 12 is tightly attached to the mounting frame 2. The elastic force of the spring 12 is used to make the pressure sensor 9 tightly attached to the mounting frame 2, ensuring that the central shaft 8 will not produce a large displacement due to slight vibration.
[0031] In this embodiment, a clearance opening 13 is provided on the frame 1, and the width of the clearance opening 13 is three times the diameter of the monitoring component, so that the mounting frame 2 can adjust its position during installation, giving the probe 10 more space to adjust to a suitable position to fit the tape.
[0032] In another embodiment, Figure 4 As shown, the middle plate 11 is movably mounted on the central shaft 8 and can slide axially along the central shaft 8. A pull plate 14 is integrally formed on the edge of the middle plate 11 to facilitate pushing the position of the middle plate 11 on the central shaft 8. The radial external thread 6 on the side wall of the middle plate 11 is connected with a locking pin 15. The locking pin 15 passes through the middle plate 11 and is interference fit with the central shaft 8, so that the middle plate 11 can be fixed on the central shaft 8. In this embodiment, by loosening the locking pin 15, the middle plate 11 can be freely moved to a suitable position, and then tightening the locking pin 15 to fix the middle plate 11, thereby adjusting the magnitude of the elastic force generated by the spring 12, and then changing the initial pressure value and sensitivity of the pressure sensor 9 to meet more monitoring needs.
[0033] The working principle of the present invention is as follows: a monitoring assembly consisting of a central axis 8, a pressure sensor 9 and a probe 10 is placed in the installation frame 2, and then one end of the probe 10 passes through the frame 1 and contacts the tape. When the tape deviates, the pressure sensor 9 monitors the pressure change between the mounting frame 2 and the pressure sensor 9. At the same time, the central axis 8 is surrounded by vertical and horizontal limit rods 4 and horizontal limit rods 5 in the mounting frame 2, and the central axis 8 is limited in the mounting frame 2 by a total of eight points on the left and right, thereby reducing the friction sensitivity generated by the installation of the assembly. When used outdoors, there is no need to worry about the mounting frame 2 and the central axis 8 rusting, nor is there any need to worry about the dispersed dust particles getting stuck in the monitoring assembly and affecting the use of the assembly when used in a mine.
[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
