Description

Technical Field

[0001] This invention relates to the technical field of conveyor belt auxiliary equipment, and more particularly to a correction device for controlling belt transport in a coal conveying system. Background Technology

[0002] In coal conveying systems, conveyor belts are the core transport equipment, responsible for moving coal from one location to another. However, belt misalignment is a frequent problem during daily operation. Belt misalignment can not only cause material spillage and accelerate belt wear, but it can also disrupt the normal operation of the production process and, in severe cases, even trigger safety accidents.

[0003] While existing belt misalignment prevention devices can correct belt deviations to a certain extent in a timely manner, they also face challenges after long-term operation. Over time, a layer of coal ash tends to accumulate on the sensor surface, which reduces the sensor's sensitivity and affects its ability to accurately detect belt misalignment.

[0034] Example 1

[0035] Reference Figures 1-6 The first embodiment of the present invention provides a correction device for controlling the belt conveying of a coal conveying system. The device includes 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] Mounting plate 200 is mounted on the outside of frame Q by bolts;

[0037] A telescopic rod 101 is fixedly connected to the output end of the cylinder 100, and a reset component 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 fixing rubber block 102b fixedly connected to one end of the mounting frame 102a, and an adjusting component 102c disposed inside the mounting frame 102a.

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

[0040] Furthermore, a slider 102c-1 is provided inside the sliding cavity 102a-1. 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 disc 102c-2. An adjusting rubber block 102c-3 is slidably connected to the outside of the disc 102c-2. A limit rod 102c-4 is fixedly connected to the top of the adjusting rubber block 102c-3. A return spring 102c-5 is provided inside the adjusting rubber block 102c-3.

[0041] One end of the return spring 102c-5 is connected to the disc 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 fixed rubber block 102b are cylindrical, and the bottom end of the adjusting rubber block 102c-3 and the top end of 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 of the mounting plate 200, a mounting bracket 202 is fixedly connected to the top of the mounting plate 200, and a signal transmitter 203 is adapted to be installed on the top of the mounting plate 200.

[0044] Preferably, the surface of the recessed groove 302b located directly above the signal transmitter 203 is set as the signal receiving surface 302c, and the limiting rod 102c-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, and a guide groove 302 is provided at the bottom end of the top plate 300. The connecting rod 301 is installed on the outer side of the mounting plate 200 by bolts.

[0046] When the conveyor belt M deviates, the belt will block the signal transmitter 203 and the signal receiving surface 302c. After the blockage lasts for a set time, the signal transmitter 203 will send a signal to the host computer and control the cylinder 100 to perform one cycle movement.

[0047] After the cylinder 100 is started, it will cause 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. Under the action of squeezing, the belt will be driven to complete the reset.

[0048] Due to the materials of the fixed rubber block 102b and the adjusting rubber block 102c-3, as well as their special cylindrical design, it can be ensured that the belt will not be damaged when it is pushed back. At the same time, the contact area with the belt can be minimized to reduce friction and ensure the belt's operating condition.

[0049] The belt is driven more stably by cooperating with the fixed rubber block 102b and the adjusting rubber block 102c-3.

[0050] Example 2

[0051] Reference Figures 1-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the guide groove 302 includes a triangular through groove 302a opened at the bottom end of the top plate 300, and a recessed groove 302b opened at each corner of the triangular through groove 302a.

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

[0053] During the single reciprocating motion of the adjusting rubber block 102c-3 by the cylinder 100, the limiting rod 102c-4 is located inside the guide groove 302. 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, it will be driven to pass through the surface of the signal transmitter 203 and reset under the guidance of the triangular through groove 302a and the sinking groove 302b. At this time, the cleaning cotton 103 at the bottom of the adjusting rubber block 102c-3 and the cleaning cotton 103 at the top of the limiting rod 102c-4 clean the surface of the signal transmitter 203 and the signal receiving surface 302c, so as to avoid the accumulation of coal ash and the decrease in sensitivity.

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

[0055] After resetting, the adjusting rubber block 102c-3 will not block the signal transmitter 203, thus ensuring that the signal transmitter 203 can work normally. At the same time, even if the cleaning cotton 103 at the bottom of the adjusting rubber block 102c-3 gets dusty, it will not affect the signal transmitter 203, further improving the practicality of the equipment.

[0056] In summary, the equipment can automatically reset the belt after it deviates. Simultaneously, it can clean the signal transmitter 203 to prevent coal ash buildup and decreased sensitivity.

[0057] Example 3

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

[0059] When the limit rod 102c-4 slides along the triangular through groove 302a into the recessed groove 302b, the elasticity of the return spring 102c-5 will cause the adjusting rubber block 102c-3 to vibrate. Thus, each time the cylinder 100 is started, three vibrations can be achieved. The vibration force will shake off the dust attached to the surface of the cleaning cotton 103, 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 equipment will be activated and perform an action. This action not only enables automatic correction of the conveyor belt, ensuring its return to normal operation, but also effectively cleans the signal transmitter 203, preventing sensor sensitivity reduction caused by coal ash accumulation.

[0061] Furthermore, the movement of cylinder 100 generates a vibration force that effectively shakes off dust adhering to the cleaning cotton 103. This process ensures that the cleaning cotton 103 can continuously and efficiently clean the signal transmitter 203, maintaining its surface cleanliness, thereby guaranteeing the reliability and response speed of the equipment monitoring system.
