Summary. Misplaced, find a hard point to pick up, raise it, and then hang it up again.

Misplaced, find a hard point to pick up, raise it, and then hang it up again.

The large scraper in the coal mine should be stuck in the east and west, how to adjust it? Wrong tooth.

The hydraulic control valve handle is pulled to the center of the brake, and the motor stops, and the chain link can be safely increased or decreased at this moment, and the length of the scraper chain is adjusted; 2. After the chain connection is completed, the hydraulic control valve hand orange roller handle is pulled to the opposite position of the tight chain operation, so that the motor Yuanchun positive running zipper, when the chain arrester is loose, the operation of the hydraulic control valve handle to the neutral position to stop supplying liquid to the hydraulic control valve, the motor stops running; Remove the chain stopper, operate the hydraulic control valve and rotate the sprocket to make the tension equalized; The tight chain system is then disconnected to disengage the idler from the bull gear. The inlet pressure of the motor brake must be limited to MPa, exceeding the limit value will cause damage to the motor, a pressure lock valve is connected before the brake is injected, when the inlet pressure is higher than MPa, the pressure lock valve will be automatically closed; When the inlet pressure is lower than MPa, the pressure lock valve will automatically open to ensure the safety of the motor brake. When the scraper chain tightener is working, the two ends of the slide chain to be connected are connected with the hook of the hydraulic chain tightener, and the hook of the chain tightener is 4 in total, 2 at each end, which are hung on the chain links at both ends respectively.

When operating, the push rod of the hydraulic cylinder is stretched out to the large stroke to ensure that the connection is reliable, and then the hand pump is operated, and the push rod of the hydraulic cylinder is retracted, and the chain links of the chutes at both ends are pulled closer to the appropriate position, and the chain links of the chutes can be connected. Operate the hand pump, switch the operation of the spare pin valve, press the handle to extend the hydraulic cylinder push rod, and remove the hook to complete the chain tightening work.

Summary. Hello, dear, (1) Running tight or not loose: During the transportation of the belt conveyor, if the center line of the front and rear rollers is not parallel, resulting in the tightness of both sides of the tape is different, the tape will deviate to the tight side; (2) Run high and not low:

The supporting roller is not in the same horizontal position parallel to the running direction of the belt, but one end is high and the other end is low, then the belt will deviate to the high end; (3) Do not run before running: The roller is not on the cross-section perpendicular to the running direction of the tape, but one end is in front and one end is behind (depending on the running direction of the tape), then the tape will deviate to the backward end.

How to deal with a section of belt conveyor belt belt that deviates inward and outward.

Hello, dear, (1) Running tight and not loose: During the transportation of the belt machine, if the center line of the front and rear rollers is not parallel, resulting in the tightness of both sides of the tape is not the same, the tape will deviate to the tight side; (2) Running high but not low: the supporting roller is not in the same horizontal position of the bend parallel to the running direction of the belt, but one end is high and the other end is low, then the belt will deviate to the high end; (3) After running and not before running:

If the roller is not in a cross-section perpendicular to the direction of the belt, but one end is in front and one end is behind (depending on the direction before the belt runs), the belt will deviate to the backward end.

Hello, dear, 1. Deviation adjustment roller method When the belt conveyor deviates from the range and the footprint is not too large, the use of the law of "running after not running before" of the belt can be automatically adjusted by the trough deviation roller. When the belt is misaligned, it touches the baffle roller on the trough deviation adjustment roller, and moves forward along the running direction of the belt due to the friction between the baffle and the edge of the belt, and the other side moves relative backward. At this point, the tape moves toward the side of the rear-turning roller until it returns to its normal position.

2. Gravity deviation method: If the belt runs off under heavy load, the roller and roller bracket of the belt deviation can be appropriately heightened, so that the weight of the material on the belt produces a component to prevent the belt from tracking until the belt returns to the normal position. 3. If the belt always deviates to one side when the belt is running, the roller can be installed vertically on the side of the belt deviation (vertical roller), so that on the one hand, the belt is forcibly reset due to the force of the vertical roller; On the other hand, due to the friction between the vertical roller and the edge of the tape, the linear velocity of the deviation side of the tape is reduced, and the linear velocity of the other side of the tape is increased relatively, so that the tape moves to the other side until it is reset. 4. If the tape is idling and always deviates to a certain side, the law of "running high and not running low" can be used to properly raise the roller bracket on the opposite side.

There are three main reasons for tape deviation:

First, the equipment itself, such as the outer cylindricity error of the drum is large, the roller rotation is not flexible, and the axis parallelism error of the driving drum and the driven drum is large;

Second, in terms of installation and commissioning, such as the installation of rollers, rollers, and racks does not meet the requirements of the specification, and the position of the coal outlet is deviated, resulting in the eccentric load of the belt and making it deviate;

The third is maintenance, mainly due to the untimely cleaning, the roller of the conveyor roller is stained with coal dust, resulting in the deviation of the local diameter and the belt deviation.

Conveyor belt deviation is the most common fault of belt conveyor, and timely and accurate treatment is the guarantee of its safe and stable operation. There are many phenomena and causes of deviation, and different adjustment methods should be adopted according to different deviation phenomena and causes in order to effectively solve the problem.

Analyze and explain the causes and handling methods of such failures

1) The axis of the head driving pulley or the tail reversing pulley is not perpendicular to the center line of the conveyor, causing the conveyor belt to deviate at the head pulley or the tail reversing drum, and the tightness of the conveyor belt on both sides of the pulley is inconsistent when the drum deviates, and the traction force FQ along the width direction is also inconsistent, and it becomes an increasing or decreasing trend, so that the conveyor belt will be attached to a moving force in a decreasing direction, resulting in the conveyor belt running away from the loose side, that is, the so-called "running loose and not running tight", Its adjustment method is for the head pulley such as the right side deviation of conveyor belt to pulley, then the bearing seat of the right side should move forward, and the left side of the conveyor belt to the left side of the pulley deviation, then the bearing seat of the left side should move forward, and the corresponding can also move back the left side bearing seat or the right side bearing seat backward. The tail drum is adjusted in the opposite way to the head roller. After repeated adjustments until the conveyor belt is adjusted to the ideal position, it is best to install it accurately before adjusting the drive or reversing the rolling.

2) The diameter is different due to processing errors, stickiness or uneven wear on the outer surface of the rolling simplification, and the conveyor belt will deviate to the side with a larger diameter. The solution to this situation is to clean up the sticky material on the surface of the drum, and replace the processing error and uneven wear and tear to reprocess the lagging treatment.

3) The blanking position at the ** point is not correct, and the blanking position has a very great impact on the deviation of the conveyor belt, especially when the projection of the upper conveyor and the conveyor in the horizontal plane is vertical. Generally, the relative height of the upper and lower belt conveyors at the ** point should be considered. The lower the relative height, the greater the horizontal velocity component of the material, the greater the lateral impact force on the lower belt, and the difficulty of centering the material.

Makes the material on the conveyor belt cross section skew, if the material is deflected to the right side the belt is deflected to the left side and vice versa. For mistracking in this case, the relative height of the two conveyors should be increased as much as possible during the design process. The form and size of the upper and lower funnels, guide troughs and other parts of the belt conveyor that are limited by space should be carefully considered.

Generally, the width of the guide trough should be about three-fifths of the width of the belt, which is more appropriate. In order to reduce or avoid belt deviation, a baffle can be added to block the material and change the direction and position of the material.

1. The quality of all conveyor belts is not good, and the two sides are not parallel (and asymmetrical with the longitudinal centerline of the conveyor belt) to form a periodic wavy shape, which causes the conveyor belt to deviate periodically; The conveyor belt joint is not good, and the cutting edge of the conveyor belt joint, that is, the joint surface, is not perpendicular to the longitudinal center line of the conveyor belt, resulting in the formation of a certain angle between the two sections of the conveyor belt, which should be a straight line, which will cause the conveyor belt to deviate. So how do we solve this problem? Huayun rubber **** will explain to you how to make the conveyor belt not deviate.

In the first case, if the quality of the conveyor belt is too poor or the conveyor belt is refurbished, if the user thinks that it can be used, adjust the joints, rollers and rollers to minimize the amount of mistracking, and increase the self-aligning idlers and anti-mistracking rollers.

For the second case, redo the belt joint; The situation of conveyor belt deviation is not only the above two situations, the specific causes of deviation are very complex, and the specific analysis should be treated, in short, the deviation should be distinguished from the head, tail, intermediate fuselage or bearing surface conveyor belt, return conveyor belt deviation, and the adjustment direction of the roller and idler should be adjusted purposefully to reduce or eliminate the deviation.
