[0034] Example 1

[0035] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, provides a correction device for controlling the belt transportation of a coal conveying system, the device comprises a cylinder 100, a mounting plate 200 and a top plate 300, the cylinder 100 is mounted on the top of the mounting plate 200, and the top plate 300 is mounted on the top of the mounting plate 200;

[0036] The mounting plate 200 is mounted on the outside of the frame Q by means of bolts;

[0037] The output end of the cylinder 100 is fixedly connected to a telescopic rod 101 , and a reset assembly 102 is provided at one end of the telescopic rod 101 .

[0038] Specifically, the reset assembly 102 includes a mounting frame 102a fixedly connected to one end of the telescopic rod 101, a fixed rubber block 102b fixedly connected to one end of the mounting frame 102a, and an adjusting member 102c disposed inside the mounting frame 102a.

[0039] Furthermore, a sliding cavity 102a - 1 is provided inside the installation frame 102a , and a guide rod 102a - 2 is fixedly connected inside the sliding cavity 102a - 1 .

[0040] Furthermore, a slider 102c-1 is disposed inside the sliding cavity 102a-1, and the slider 102c-1 is slidably connected to the outside of the guide rod 102a-2, one end of the slider 102c-1 is fixedly connected to a disk 102c-2, an adjusting rubber block 102c-3 is slidably connected to the outside of the disk 102c-2, a top end of the adjusting rubber block 102c-3 is fixedly connected to a limiting rod 102c-4, and a return spring 102c-5 is disposed inside the adjusting rubber block 102c-3;

[0041] Among them, one end of the return spring 102c-5 is connected to the disk 102c-2, and the other end of the return spring 102c-5 is connected to the inner wall of the adjusting rubber block 102c-3.

[0042] Preferably, the adjusting rubber block 102c - 3 and the fixing rubber block 102b are cylindrical in design, and the bottom end of the adjusting rubber block 102c - 3 and the limiting rod 102c - 4 are provided with cleaning cotton 103 .

[0043] It should be noted that a right-angle plate 201 is fixedly connected to the bottom end of the mounting plate 200 , a mounting frame 202 is fixedly connected to the top end of the mounting plate 200 , and a signal transmitter 203 is adapted to be installed on the top end of the mounting plate 200 .

[0044] Preferably, the surface of the sinking groove 302 b located directly above the signal transmitter 203 is set as the signal receiving surface 302 c, and the limiting rod 102 c - 4 is set inside the guide groove 302 .

[0045] Preferably, a connecting rod 301 is fixedly connected to the outer side of the top plate 300 , a guide groove 302 is provided at the bottom end of the top plate 300 , and the connecting rod 301 is installed on the outer side of the mounting plate 200 by bolts.

[0046] When the conveyor belt M is offset, the belt will be blocked between the signal transmitter 203 and the signal receiving surface 302c. After being blocked for a set time, the signal transmitter 203 will send a signal to the host computer and control the cylinder 100 to perform a periodic motion.

[0047] After being started, the cylinder 100 will drive the fixed rubber block 102b and the adjusting rubber block 102c-3 at one end of the telescopic rod 101 to slide and squeeze the outer side of the offset belt, and the belt will be driven to complete the reset under the effect of squeezing.

[0048] Due to the material of the fixed rubber block 102b and the adjusting rubber block 102c-3 and the special cylinder design, it can be ensured that the belt will not be damaged when it is pushed to reset. At the same time, the contact area with the belt can be reduced as much as possible, thereby reducing friction and ensuring the running state of the belt.

[0049] The belt is pushed more stably by the cooperation of the fixed rubber block 102b and the adjustable rubber block 102c-3.

[0050] Example 2

[0051] Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the guide groove 302 includes a triangular through groove 302a opened at the bottom end of the top plate 300, and a sinking groove 302b opened at each corner of the triangular through groove 302a.

[0052] Furthermore, the depth of the sinking groove 302b is greater than that of the triangular through groove 302a, and one end of the sinking groove 302b is connected to the triangular through groove 302a through an inclined surface.

[0053] During the process of the adjusting rubber block 102c-3 being subjected to a single reciprocating motion by the cylinder 100, the limiting rod 102c-4 is located inside the guide groove 302, and with the cooperation of the triangular through groove 302a and the sinking groove 302b, after the adjusting rubber block 102c-3 pushes the belt to reset, under the guidance of the triangular through groove 302a and the sinking groove 302b, the adjusting rubber block 102c-3 will be driven to reset after passing through the surface of the signal transmitter 203. At this time, the cleaning cotton 103 at the bottom end of the adjusting rubber block 102c-3 and the cleaning cotton 103 at the top end of the limiting rod 102c-4 are used to clean the surfaces of the signal transmitter 203 and the signal receiving surface 302c to avoid the accumulation of coal ash and the decrease in sensitivity.

[0054] At the same time, since the adjusting rubber block 102c - 3 slides inside the guide rod 102a - 2 through the slider 102c - 1 , it can be ensured that the adjusting rubber block 102c - 3 moves along the guide groove 302 .

[0055] After reset, the adjusting rubber block 102c-3 will not block the signal transmitter 203, thereby ensuring that the signal transmitter 203 works normally. Meanwhile, even if the cleaning cotton 103 at the bottom of the adjusting rubber block 102c-3 is covered with dust, it will not affect the signal transmitter 203, further improving the practicability of the device.

[0056] In summary, the device can automatically reset the belt after the belt is offset, and can clean the signal transmitter 203 to avoid the accumulation of coal dust and the decrease of sensitivity.

[0057] Example 3

[0058] Reference Figure 6 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that:

[0059] When the limiting rod 102c-4 slides along the triangular through groove 302a to the inside of the sinking groove 302b, the elasticity of the reset spring 102c-5 will drive the adjusting rubber block 102c-3 to vibrate, so that every time the cylinder 100 is started once, three vibrations can be achieved. The dust attached to the surface of the cleaning cotton 103 will be shaken off by the vibration force, ensuring that the cleaning cotton 103 can effectively clean the signal transmitter 203.

[0060] In summary, when the conveyor belt deviates, the cylinder 100 in the device will be activated and perform an action. This action can not only realize the automatic correction of the conveyor belt to ensure that it returns to normal operation, but also effectively clean the signal transmitter 203 to prevent the problem of reduced sensor sensitivity caused by coal ash accumulation.

[0061] In addition, the movement of the cylinder 100 generates a vibration force, which can effectively shake off the dust attached to the cleaning cotton 103. This process ensures that the cleaning cotton 103 can continuously and efficiently clean the signal transmitter 203 and maintain the cleanliness of its surface, thereby ensuring the reliability and response speed of the equipment monitoring system.
