[0002] As one of my country's main energy sources, coal plays a key role in many industries such as electricity, steel, and chemicals. Therefore, coal transportation is an important link in ensuring national energy security and stable economic development, and is the key to ensuring the industry's production operations and energy supply.

[0003] At present, the belt is the throat of coal transportation. During the production process, the comprehensive mining working face and the tunneling working face need to shorten and extend the belt length every shift to ensure normal production operations of the working face. After the belt conveyor shortens and extends the belt length, the belt will deviate, causing wear of the belt and H-frame, reducing the service life of the belt and H-frame. In mild cases, the machine will be shut down for maintenance, affecting normal production. In severe cases, it is easy to cause belt tearing, affecting safe production, causing direct economic losses, or friction fire threatens mine safety. Therefore, a belt anti-deviation device is needed.

[0004] The current belt anti-deviation device usually uses multiple sets of bolts to install two sets of anti-deviation rollers on the head, body frame and tail frame. The installation takes a long time, and when the belt length needs to be shortened or extended, the position of the anti-deviation rollers must be adjusted in sequence, making the entire installation and adjustment operation time-consuming and labor-intensive, delaying the transportation time of coal. Therefore, it needs to be improved and optimized. Utility Model Content

[0025] 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.

[0026] like Figures 1 to 7 As shown, the utility model provides a belt deviation prevention device, including a belt H frame 1, lower roller frames 2 are fixedly installed on the left and right sides of the belt H frame 1, and the tops of the two groups of lower roller frames 2 are fixedly installed with fixed grooves 4, and the interiors of the fixed grooves 4 are clamped with belt lower rollers 3, and the belt lower rollers 3 are rotatably installed between the two groups of lower roller frames 2;

[0027] A locating pin 6 is clamped in the fixed groove 4 at the front end of the lower roller frame 2, and a fixing frame 5 is fixedly installed on both ends of the locating pin 6. A connecting plate 7 is fixedly installed on the front end of the fixing frame 5, and a movable plate 8 is movably installed inside the connecting plate 7. A vertical roller fixing sleeve 9 is fixedly installed at the front end of the movable plate 8. The lower vertical roller 12 is sleeved on the interior of the vertical roller fixing sleeve 9, and an upper vertical roller 14 is fixedly installed on the top of the lower vertical roller 12. Bearings 15 are fixedly installed on the upper and lower ends of the outer wall of the upper vertical roller 14, and a vertical roller sleeve 18 is fixedly installed on the outer wall of the bearing 15. The upper vertical roller 14 is located inside the vertical roller sleeve 18.

[0028] Before the belt is transported, the staff first sleeves the lower vertical roller 12 inside the vertical roller fixing sleeve 9, and then rotates the bolt 11 to make the bolt 11 move along the nut 10 toward the inside of the vertical roller fixing sleeve 9. At this time, the bolt 11 and the limiting step 13 in the middle of the lower vertical roller 12 abut against each other, so that the lower vertical roller 12 is reliably fixed. Then the staff aligns the locating pins 6 between the two sets of fixing frames 5 with the fixing groove 4 and clamps the locating pins 6 into the inside of the fixing groove 4, so that the deviation device is installed. At this time, the belt starts the transportation operation. When the belt deviates, the belt will contact the outer wall of the vertical roller sleeve 18. At this time, the belt will drive the vertical roller sleeve 18 to rotate through friction. Further, the vertical roller sleeve 18 and the bearing 15 rotate synchronously, but because the limiting step 13 in the middle of the lower vertical roller 12 is bolted 11 is fixed. At this time, the upper vertical roller 14 does not rotate, and only the vertical roller sleeve 18 rotates. At this point, the position of the vertical roller sleeve 18 is fixed, which will prevent the belt from deviating, and the vertical roller sleeve 18 will rotate with the belt to prevent the friction between the belt and the vertical roller sleeve 18 from increasing. When the belt is narrow, the staff can rotate the knob 22 to rotate the screw 21. The rotation of the screw 21 drives the movable plate 8 threadedly connected to it to move along the guide groove 20 toward the middle of the belt H frame 1. The distance between the two sets of vertical roller sleeves 18 is further reduced, thereby adapting to all types of belts. When the belt is adjusted, the device needs to be disassembled. At this time, the staff only needs to lift the fixing frame 5 upwards and turn the bolt 11 to make the bolt 11 leave the inside of the limit step 13 to complete the disassembly of the vertical roller fixing sleeve 9 and the lower vertical roller 12. It is simple and convenient.

[0029] By connecting the lower vertical roller 12 and the vertical roller fixing sleeve 9, the installation of the lower vertical roller 12 is completed by rotating the bolt 11, and the positioning pin 6 between the two sets of fixing frames 5 is clamped into the inside of the fixing groove 4, so that the anti-deviation device is installed. At this time, the vertical roller sleeve 18 will prevent the belt from deviating. Compared with the traditional device, the device can easily disassemble the anti-deviation vertical roller and the vertical roller fixing sleeve, and install it by clamping the positioning pin 6 into the inside of the fixing groove 4. The entire installation process does not require the use of additional tools, which is convenient and quick, so that the device can be easily repaired when it fails, thereby improving work efficiency and reducing workload.

[0030] Among them, a guide groove 20 is opened inside the connecting plate 7, and a movable plate 8 is movably installed inside the guide groove 20. A screw 21 is rotatably installed inside the guide groove 20, and the screw 21 and the movable plate 8 are threadedly connected. A knob 22 is rotatably installed on the outer wall of the connecting plate 7, and the knob 22 and the screw 21 are threadedly connected.

[0031] When the belt is narrow, the staff can rotate the knob 22 to rotate the screw 21. The rotation of the screw 21 drives the movable plate 8 threadedly connected to it to move along the guide groove 20 toward the middle of the belt H frame 1. The distance between the two sets of roller sleeves 18 is further reduced, thereby adapting to all types of belts.

[0032] By rotating the knob 22, the movable plate 8 is displaced along the guide groove 20 toward the middle of the belt H frame 1, and the distance between the two sets of vertical rollers 18 is further reduced. Compared with the traditional device, this device adjusts the distance between the two sets of vertical rollers 18 by rotating the knob 22, adapting to all types of belts, improving the flexibility of the device, and ensuring the efficiency of preventing deviation.

[0033] Among them, nuts 10 are welded to the outer walls of the left and right sides of the vertical roller fixing sleeve 9, and bolts 11 are sleeved on the internal threads of the nuts 10.

[0034] Nuts 10 are welded to the left and right ends of the vertical roller fixing sleeve 9, so that bolts 11 can be installed on the left and right sides of the vertical roller fixing sleeve 9, which is convenient for adjusting the belt when it deviates.

[0035] A limiting step 13 is provided in the middle of the lower vertical roller 12 , and the limiting step 13 and the bolt 11 abut against each other.

[0036] The bolt 11 moves along the nut 10 toward the interior of the vertical roller fixing sleeve 9. At this time, the bolt 11 and the limiting step 13 in the middle of the lower vertical roller 12 abut against each other, thereby reliably fixing the lower vertical roller 12.

[0037] The upper and lower ends of the inner wall of the vertical roller sleeve 18 are provided with retaining springs 17 , and one end of the retaining spring 17 is provided with a retaining ring 16 . The retaining ring 16 is located between the two sets of bearings 15 and the retaining spring 17 .

[0038] The circlip 17 is responsible for preventing the bearing 15 from being separated and locking the retaining ring 16 via the circlip 17 .

[0039] The bearing 15 and the upper vertical roller 14 are sleeved together, and the retaining ring 16 is responsible for fixing the bearing 15 and the retaining ring 16 .

[0040] When the vertical roller sleeve 18 rotates, the outer side of the bearing 15 rotates along with the vertical roller sleeve 18 , while the inner side of the bearing 15 does not rotate like the upper vertical roller 14 .

[0041] A protective sleeve 19 is sleeved on the outer wall of the upper vertical roller 14 , and the protective sleeve 19 is located between the two sets of bearings 15 .

[0042] Responsible for reducing the wear of the upper vertical roller 14.

[0043] The working principle and use process of this utility model:

[0044] Before the belt is transported, the staff first sleeves the lower vertical roller 12 inside the vertical roller fixing sleeve 9, and then rotates the bolt 11 to make the bolt 11 move along the nut 10 toward the inside of the vertical roller fixing sleeve 9. At this time, the bolt 11 and the limiting step 13 in the middle of the lower vertical roller 12 abut against each other, so that the lower vertical roller 12 is reliably fixed. Then the staff aligns the locating pins 6 between the two sets of fixing frames 5 with the fixing groove 4 and clamps the locating pins 6 into the inside of the fixing groove 4, so that the deviation device is installed. At this time, the belt starts the transportation operation. When the belt deviates, the belt will contact the outer wall of the vertical roller sleeve 18. At this time, the belt will drive the vertical roller sleeve 18 to rotate through friction. Further, the vertical roller sleeve 18 and the bearing 15 rotate synchronously, but because the limiting step 13 in the middle of the lower vertical roller 12 is bolted 11 is fixed. At this time, the upper vertical roller 14 does not rotate, and only the vertical roller sleeve 18 rotates. At this point, the position of the vertical roller sleeve 18 is fixed, which will prevent the belt from deviating, and the vertical roller sleeve 18 will rotate with the belt to prevent the friction between the belt and the vertical roller sleeve 18 from increasing. When the belt is narrow, the staff can rotate the knob 22 to rotate the screw 21. The rotation of the screw 21 drives the movable plate 8 threadedly connected to it to move along the guide groove 20 toward the middle of the belt H frame 1. The distance between the two sets of vertical roller sleeves 18 is further reduced, thereby adapting to all types of belts. When the belt is adjusted, the device needs to be disassembled. At this time, the staff only needs to lift the fixing frame 5 upwards and turn the bolt 11 to make the bolt 11 leave the inside of the limit step 13 to complete the disassembly of the vertical roller fixing sleeve 9 and the lower vertical roller 12. It is simple and convenient.
