Description

Meander prevention device for conveyors {MEANDERING PREVENTION DEVICE FOR CONVEYER BELT}

The present invention relates to a meandering prevention device for a conveyor, and more particularly, to prevent the kenvey belt from meandering in the process of transporting raw materials, to smoothly transport the raw materials and to maintain high quality while extending the life of the conveyor. It is related with the provision of a prevention device.

In steel mills, power plants, or cement planting systems, conveyors are installed and used as a means to transport raw materials such as iron ore, coke, coal, limestone, and sand for a stable long distance.

The conveyor as described above may cause meandering in the process of transferring the raw materials, causing damage to the belt and the conveyor, as well as causing the raw materials not to be transferred normally.

The cause of meandering is caused by the shift of the center of gravity of the belt due to the difference in the weight of the raw material supplied to the conveyor for conveying, and the belt at the position returning after conveying the raw material has no load and is fast. It is caused by rolling caused by speed.

In order to prevent the belt from meandering due to this cause, a meandering prevention device is installed in the return portion of the Kenveyer to prevent the meandering of the belt, and this technology will be described below with reference to FIG. 6.

The belt meandering prevention device (1) to which the prior art is applied allows the belt (4) held by the carrier roller (3) to the upper side of the conveyor frame (2) to convey the raw material (5), and the conveyor frame (2). ) Is provided to prevent the belt 4 returned from the lower side from meandering (moving in the belt width direction).

The adjustment roller 8 is installed on the adjustment bracket 7 provided on the lower bar 6 of the conveyor frame 2, and the guide roller 9 is installed on both ends of the adjustment bracket 7 so as to stand upright. Therefore, the belt 4 is configured to restrict movement.

In the prior art as described above, the belt in the return direction is connected to the guide roller in the process of meandering to prevent further meandering or deviating phenomenon, which is connected to the belt in the process of being continuously repeated for a long time, causing friction. Intensive wear of the guide roller occurs.

As described above, when the belt is excessively biased in any one direction, the guide roller does not maintain its position due to the pushing force of the belt and the shaft is bent.

If this phenomenon is excessive, the guide roller will be broken, and if the guide roller is broken, the belt will meander in the broken direction, and in particular, since the damaged part of the guide roller will be sharp, it will meander in the role of knife. It will damage the belt.

In addition, when excessively biased force occurs in one direction of the belt, the belt may enter and be pinched between the adjustment brackets, causing damage such as torn in the process of returning.

In this case, when the belt is damaged during the return process, the raw material is not transferred normally and falls during the carrier process. In addition, when the belt is severely damaged, the belt is cut in the process of transferring the raw material due to the concentrated load on the damaged part. The phenomenon occurs.

In addition, since the returned belt is in contact with the adjusting roller and the guide roller to cause friction, not only does it cause considerable noise, but also the friction surface increases, which is another cause of easy belt damage.

In the prior art as described above, damage to the meandering prevention device and the belt frequently occurs, and excessive maintenance manpower and time and cost are required to maintain it in a normal state, and the transfer of raw materials cannot be stably performed. There are a number of problems, such as being caused.

Accordingly, the present invention is invented to solve the above problems, the belt is maintained on the upper side of the conveyor frame is installed so as to transport the raw material, the lower side of the conveyor frame prevents the belt returned from meandering. In the conveyor is installed meandering prevention device for;

The meandering prevention device includes a meandering prevention bar which is freely coupled to the center of the lower bar of the conveyor frame through a bearing, a pair of tapered rollers installed on both sides of the meandering prevention bar, and a meandering prevention bar provided at the meandering prevention bar. Including a stopper that prevents endless rotation, it minimizes the meandering of the returned belt while simplifying the configuration, thereby increasing the conveying power of raw materials, minimizing the damage of the conveyor, and providing ease of maintenance. It is possible to achieve the purpose of maintaining high quality while prolonging the life of the product.

The present invention can be installed at the return position of the conveyor to prevent the belt from meandering, and also to prevent deformation and damage of the belt and the meandering prevention device to prolong the service life of the conveyor, and to maintain the quality of the conveyor while maintaining it. It is an invention having various effects such as unnecessary manpower and cost that can be reduced according to the repair.

Conventional conveyor 100 is installed on the upper side of the conveyor frame 101 so that the belt 103 held by the carrier roller 102 can transport the raw material 104, the lower side of the conveyor frame 101 The meandering prevention device 105 is installed to prevent the returned belt 103 from meandering.

In the present invention is characterized by improving the meandering prevention device 105 to prevent meandering of the belt while having a simple configuration.

The meandering prevention device 105 is coupled to the meandering prevention bar 107 to move freely through a bearing in the center of the lower bar 106 of the conveyor frame 101, and to both sides of the meandering prevention bar 107. A pair of tapered rollers 108 and 109 having a truncated cone shape is installed.

The tapered rollers 108 and 109 are held by the roller bracket 110 fixed to the meandering bar 107 by welding or the like, and the small diameter portions 111 of the tapered rollers 108 and 109 are located outside and large diameter portions. 112 is installed to be located inside.

This is to ensure that the belt 103 is always located in the center of the tapered rollers 108 and 109 due to the phenomenon that the large diameter portion 111 is about to rotate quickly based on the principle that the returned belt 103 moves toward the higher speed. For sake.

The stopper 113 for preventing the meandering bar 107 from rotating indefinitely is further provided at the front and rear sides (the direction in which the belt moves) at any one of the left and right sides of the meandering bar 107.

The stopper 113 is a restriction piece 114 that protrudes to the front and rear of the meandering bar 107 to bend downward, and the restriction piece 114 in combination with a bolt 115 and a nut 116 to the restriction piece 114. And a positioning means 117 which determines the rotation angle range of the meandering prevention bar 107 by adjusting the distance between the 114 and the meandering prevention bar 107.

The rubber coating 118 may be applied to the surfaces of the tapered rollers 108 and 109 to increase the coefficient of friction with the belt 103 so that the belt 103 does not leave the tapered rollers 108 and 109 as much as possible.

Looking at the process to prevent the meandering of the belt 103 of the conveyor returned by the meander prevention device 105 for the conveyor to which the technique of the present invention as described above is as follows.

The belt 103 held by the carrier roller 102 installed on the upper side of the Kenvey frame 101 is placed with the raw material 104 and transferred to a predetermined destination, and the belt 103 has been transferred to the raw material 104. As it is returned to move in the downward direction, the meandering device 105 is prevented from meandering in this process.

That is, in the process of moving (returning) the belt 103, the belt 103 is always guided to the center position by the tapered rollers 108 and 109 installed on the meandering prevention bar 107, which means that the belt 103 moves. (Or rotation) occurs to move toward the higher speed, the shape of the tapered rollers 108, 109 to be installed on the meandering prevention bar 107, the small diameter portion 111 is located on the outside and the large diameter portion 112 on the inside. Since the position is naturally moved to the large diameter portion 112 to rotate quickly is possible.

In addition, when the belt 103 is biased in one direction while returning, the anti-skid bar 107 performs a predetermined angular movement with respect to the lower bar 106 at the starting point P in the biased direction. Since the belt 103 is rotated in the direction in which the belt 103 is to be shifted, a force is generated to move the belt 103 back to an intermediate position of the tapered rollers 108 and 109 to prevent meandering.

At this time, the force F to move the belt 103 to the center of the tapered rollers 108 and 109 is the tension F1 of the side (meandering direction) in which the belt 103 is relaxed and the belt 103 move to a higher speed. Since the belt 103 is naturally moved toward the center of the tapered rollers 108 and 109 because the force F2 is equal to the sum of the forces F2, the meandering is prevented.

In particular, the rubber coating 118 is formed on the surfaces of the tapered rollers 108 and 109 to increase the coefficient of friction with the belt 103, thereby helping to prevent the belt 103 from leaving the tapered rollers 108 and 109. .

The present invention, while simplifying the configuration of the meander prevention device to suppress the meandering of the returned belt as much as possible to increase the feed force of the raw material, to minimize the damage of the conveyor can provide ease of maintenance as well as to increase the life of the conveyor It has the advantage of maintaining high quality while long.
