The handling method for belt slippage in belt conveyors is a common fault during the operation of belt conveyors. To solve this common malfunction, it is crucial to pay attention to the installation and processing accuracy, as well as daily maintenance and upkeep of the conveyor. There are many and diverse reasons for directional deviation, which need to be addressed according to different reasons.
- When adjusting the load-bearing roller group of the conveyor belt, the equipment of the conveyor belt needs to adjust the position of the roller group to adjust the direction deviation when the drive belt deviates in the central and southern directions of all belt conveyors; During production, the installation holes on both sides of the roller group are produced and processed to facilitate adjustments. The method is to determine which side of the conveyor belt is biased, which side of the conveyor roller group is shifting towards the correct direction of the conveyor belt, or which side is moving backwards. If the conveyor belt moves upwards and the vehicle deviates, the rear position of the roller group should be moved to the left, and the fabric of the roller group should be moved to the right.
- The assembly of conveyor centering roller group There are various types of conveyor centering roller group, such as central transmission shaft type, four connecting rods, vertical roller type, etc. Its function is to use blocking or roller support to rotate in the plane of the conveyor to block or generate transverse driving force, so that the transmission belt can automatically adjust the radial direction to achieve the effect of belt slippage. This method is generally suitable for short total length or dual operation of belt conveyors. The main reason for using a shorter belt conveyor is that it is more prone to direction deviation and difficult to adjust. It is best not to use this method for long belt conveyors, as the application of centering roller groups can cause certain harm to the service life of the transmission belt.
- The adjustment of the driving drum and the changing drum of the conveyor is an important part of adjusting the deviation of the belt. Due to the fact that a belt conveyor has at least 2 to 5 rollers, the installation of all rollers must be perpendicular to the axis of the length direction of the belt conveyor. If the conveyor tilts too much, it will inevitably cause directional deviation. Its adjustment method is similar to adjusting the roller group. If the conveyor belt deviates towards the right side of the roller, the right seat bearing should move forward. If the conveyor belt deviates towards the left side of the roller, the left seat bearing should move forward. Correspondingly, the left seat bearing can also be moved backward or the right seat bearing can be moved backward. The method of changing the tail end barrel is exactly the opposite of rolling the head top barrel. The conveyor is continuously adjusted until the transmission belt is adjusted to the ideal position. Before changing the push or direction of the drum, it is necessary to accurately assemble its parts.
- Adjusting the tensioning position of the conveyor belt is a crucial process for adjusting the direction deviation of the belt conveyor. The two directional rollers at the upper end of the heavy hammer tension should not only be perpendicular to the length direction of the belt, but also perpendicular to the vertical line of the force, ensuring that their axis lines are level. When using spiral tensioning or hydraulic cylinder tensioning, the two main seat bearings of the tensioning roller should move simultaneously, and the conveyor should ensure that the transmission drum line and transmission belt are vertically oriented. The specific method for changing belt slippage is similar to adjusting at the barrel.
- The impact of material falling at the turning point on belt slippage is significant for the direction deviation of the conveyor belt, especially when the projection of two belt conveyors on the river plane is vertical. The absolute height of the two belt conveyors on the left and right at the turning point should generally be considered. The smaller the absolute height of the conveyor, the more the horizontal velocity component of the material, and the greater the lateral impact on the next layer of the transmission belt. At the same time, it is also difficult for the raw materials to be vertically centered. The conveyor causes the raw materials in the cross section of the transmission belt to tilt, which in turn causes the belt to slip. If the raw materials are offset to the right, the conveyor belt will be offset to the left, and vice versa. In the planning process, the absolute height of two belt conveyors should be increased as much as possible. The way and specifications of moving the front and rear Buchner funnels, guide chutes, and other components of the disc conveyor machinery due to indoor space limitations should be carefully considered. The total width of the general guide groove should be two-thirds of the width of the belt, and it is more suitable for the upper and lower parts. To prevent the belt from slipping, the material blocking plate can be raised to block the raw materials, and the direction and position of material falling can be changed.
- The change of direction deviation of double operation belt conveyor The change of belt slip of double operation belt conveyor is much more difficult than the change of direction deviation of single operation belt conveyor. In actual adjustment, one direction should be adjusted first, and then another. When adjusting, it is necessary to carefully observe the correlation between the speed direction of the transmission belt and the direction deviation market, and make adjustments one by one. The key to the conveyor lies in the changes of the driving drum and the reversing drum, followed by the changes of the buffer roller and the material drop point. At the same time, it is necessary to pay attention to the balanced load-bearing capacity of the transmission belt in the long and short directions of the cross-section when using vulcanization joints for the conveyor. When using guide chain traction, the load-bearing capacity on both sides of the conveyor should be as similar as possible
