[0021] 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.

[0022] An embodiment provided by the present invention: Figure 1 As shown, a coal conveying deviation correction device includes a supporting base frame 1, an inner belt bracket 2, an outer belt bracket 3 and a silica gel layer 4.

[0023] like Figure 1 As shown, the inner and outer belt brackets 2 and 3 are mounted above the support base 1. Two sets of outer belt brackets 3 are symmetrically arranged around the inner belt brackets 2. These inner and outer belt brackets 2 and 3 support the belt conveyor for conveying coal. The side rollers 32 and transverse rollers 23 are angled, creating an inverted opening on the belt. Compared to a flat belt, this prevents the collected coal from falling off the track. Furthermore, the inner and outer belt brackets 2 and 3 sandwich the belt, preventing it from straying from its path.

[0024] like Figure 2 As shown, the inner belt bracket 2 includes a first positioning member 21, a first bearing 22, and a transverse roller 23. The first positioning member 21 is fixed to the supporting base frame 1 and is provided in two groups. The two ends of the transverse roller 23 are connected to the first positioning member 21 through the first bearing 22. The transverse roller 23 rotates between the two groups of first positioning members 21. The bottom of the belt abuts against the transverse roller 23. When the driven belt passes through, the transverse roller 23 rotates accordingly. The first bearing 22 makes the belt rotate more flexibly when passing through the transverse roller 23.

[0025] like Figure 3As shown, the belt outer bracket 3 includes a fixed connection end 31 and a side roller 32. One end of the side roller 32 is hingedly connected to the support base 1 via the fixed connection end 31. The fixed connection end 31 includes a second positioning member 311 and a rotating member 312. The second positioning member 311 is fixed to the support base 1, and the rotating member 312 is hingedly connected to the second positioning member 311. By setting the fixed connection end 31, the side roller 32 can be rotated to adjust the angle between it and the support base 1. The fixed connection ends 31 on both sides can be adjusted separately. When the belt runs to one side, the side roller 32 on this side rotates to increase the angle between it and the support base 1. When the side roller 32 on this side is tilted more than the other side, it drives the belt back to the center. During the adjustment process, the rotation angle of the side roller 32 can be adjusted accordingly according to the degree of belt deviation, so that the belt can be quickly and efficiently adjusted to the appropriate position.

[0026] The surfaces of the transverse roller 23 and the side roller 32 are both covered with a silicone layer 4, which is made of a flexible material. The silicone layer 4 has a high degree of fit with the belt, increasing friction and making the belt conveying coal smoother.

[0027] The outer belt bracket 3 also includes a movable connection end 34 and a hydraulic actuator 35. The movable connection end 34 includes a connector 341. The connector 341 of the movable connection end 34 is provided at the other end of the side roller 32. The connector 341 is connected to the support base 1 via the hydraulic actuator 35. The main body of the hydraulic actuator 35 is hingedly connected to the support base 1, and the output end of the hydraulic actuator 35 is hingedly connected to the bottom of the connector 341. During the angle adjustment process of the side roller 32, the hydraulic actuator 35 drives the connector 341 to complete the rotation of the side roller 32 around the fixed connection end 31.

[0028] The outer belt bracket 3 also includes a second bearing 33. One end of the side roller 32 is connected to the fixed connection end 31 via the second bearing 33 mounted on the rotating member 312. One end of the side roller 32 is connected to the movable connection end 34 via the second bearing 33 mounted on the connecting member 341. The side roller 32 rotates between the two sets of movable connection ends 34 and the fixed connection end 31. The bottom of the belt edge abuts the top of the side roller 32. When the driven belt passes, the side roller 32 rotates accordingly. The second bearing 33 allows the belt to rotate more flexibly when passing the transverse roller 23.

[0029] like Figure 4As shown, the movable connection end 34 includes a connector 341, a pressure sensor 342, a spring 343, a compression member 344, and a warning light 345. The sensing end of the pressure sensor 342 is mounted on the side of the connector 341 facing the side roller 32. The sensing end surface of the pressure sensor 342 is connected to the compression member 344 via a spring 343. Multiple groups of springs 343 are provided between the pressure sensor 342 and the compression member 344. The output end of the pressure sensor 342 is electrically connected to the warning light 345. The warning light 345 is located at the top of the connector 341. Once the belt deviates to one side, the edge of the belt on this side will approach the compression part 344 of the movable connecting end 34. During the belt deviation process, the belt continuously generates pressure on the compression part 344. Under the action of pressure, the spring 343 of the compression part 344 is compressed, and the compression part 344 will approach the connecting part 341. The sensing end of the pressure sensor 342 on the connecting part 341 will transmit the pressure signal reaching the specified value to the warning light 345, making the warning light 345 light up, which can promptly remind the staff of the belt deviation, facilitate the next step of adjusting the angle of the cross roller 23, ensure the linear movement of the belt, and improve the efficiency of coal transportation.

[0030] like Figure 5 As shown, the compression member 344 includes a fixed seat 3441, a limiting shaft 3442, and a roller 3443. The fixed seat 3441 is connected to one end of the spring 343. Multiple sets of limiting shafts 3442 are installed on the fixed seat 3441. The rollers 3443 are sleeved and rotatably connected to the limiting shafts 3442. The rollers 3443 and limiting shafts 3442 are arranged in a one-to-one correspondence. When the edge of the belt pushes the compression member 3444, the edge of the belt sticks to the roller 3443. As the belt moves, the roller 3443 also rotates accordingly, reducing the resistance of the belt movement, preventing conveying jams, and maintaining normal conveying speed.

[0031] The rotation adjustment of the hydraulic press 35 driving the side roller 32 of the device can also be connected to the pressure sensor 342 through the control module. The pressure sensor 342 transmits the signal to the control module. The control module directly drives the hydraulic press 35 to operate. At the same time, according to the pressure of the pressure sensor 342, the rotation angle of the side roller 32 driven by the hydraulic press 35 is adjusted, saving manpower.

[0032] The above are only embodiments of the present invention, and common knowledge such as the specific structures and characteristics of the scheme are not described in detail here. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claim involved.
