Description

Belt conveyor counterweight box, counterweight system and belt deviation rectifying method

Technical Field

The invention relates to the technical field of belt conveyor equipment, in particular to a belt conveyor counterweight box, a counterweight system and a belt deviation rectifying method.

Background

The belt conveyer is a friction-driven machine for continuously conveying materials, and is applied to bulk material conveying in the fields of metallurgy and mines. During the operation of the belt conveyor, it is necessary to ensure that the belt has a sufficient tension. The weight box is used for tensioning a belt in the belt conveyor, and provides tension for the belt by using gravity. The weight box can keep the tension force stable under various working conditions, can automatically compensate the elongation of the belt, and is a tensioning device widely applied at present.

The weight box in the prior art is usually an open iron box, and the purpose of weight balancing is realized by bulk balancing weights; in the process of counterweight loading, loading is carried out according to the designed number of the counterweight blocks. However, when the counterweight is loaded on site, the installer often forgets the number of the loaded counterweight blocks, and the counterweight blocks transported to the site are easy to be out of design; in some cases, the installer will use a weight such as stone to perform the loading. This often results in a weight load that does not match the design weight. When the loading capacity is insufficient, the tension force of the belt conveyor is insufficient, and the belt slips; when the loading is excessive, the tensioning force can be overlarge, the stress of the equipment is overlarge, the service life of the equipment is influenced, and the risk of directly causing installation accidents exists in the overlarge counterweight loading.

EXAMPLE III

The invention provides a belt deviation rectifying method of a belt conveyor, which adopts the belt conveyor counterweight system and comprises the following steps as shown in figure 9:

step S10, confirming the deviation direction of the belt;

As shown in fig. 10, in some cases, the distribution of the weight 40 in the weight box is biased to one end, so that the center of gravity of the weight box is biased to one end, and the stress is not balanced at both ends of the drum 200, resulting in the deviation of the belt 300. As shown in fig. 11, in other cases, the belt 300 may be displaced in the drum 200 due to problems in processing, assembling, and the like of the drum 200 and the like in the belt conveyor.

According to the belt deviation rectifying method, the gravity center of the whole weight box and the balancing weight 40 moves along the deviation direction 500 to adjust the stress of two ends of the roller 200, so that the belt 300 moves on the roller 200 along the reverse direction 510 of the deviation direction and returns to the designed position.

In an embodiment of the present invention, the drum 200 has a symmetry plane 210 perpendicular to its axis; the weight box is provided with a first weight area 110 and a second weight area 120 which are distributed along the deviation direction 500, the first weight area 110 and the second weight area 120 are positioned at two sides of the symmetrical plane 210, and the first weight area 110 and the second weight area 120 are respectively provided with a plurality of weight compartments 20; as shown in fig. 12, step S20 includes: decreasing the number of clump weights 40 in the first weight region 110 and/or increasing the number of clump weights 40 in the second weight region 120 to achieve a shift of the center of gravity of the overall weight box and clump weight 40 in the off-tracking direction 500. Preferably, in step S20, an appropriate number of weights 40 in the first weight region 110 are moved to the second weight region 120 so that the total weight of the weights is constant and the center of gravity position is adjusted.

Further, the belt deviation rectifying method further comprises the following steps: in step S30, the distribution position of the weight 40 in the weight layer 10 is adjusted so that the center of gravity of the entire weight box and the weight is shifted in the direction opposite to the running direction 510, thereby stabilizing the position of the belt 300 on the drum 200.

For example, when the belt runs off the track as shown in fig. 10, after the belt 300 returns to the design position, the number of weights in the first weight region 110 and the second weight region 120 is adjusted again so that the center of gravity of the whole weight box and the weight 40 is maintained on the symmetry plane 210.

When the belt deviates as shown in fig. 11, after the belt 300 returns to the designed position, the number of the counter weights in the first counter weight region 110 and the second counter weight region 120 is adjusted again, and the deviation distance of the center of gravity of the whole weight box and the counter weight 40 with respect to the symmetric plane 210 is reduced, so that the belt 300 is prevented from continuously moving along the reverse direction 510 of the deviation direction, and the position of the belt 300 on the roller 200 is kept stable through debugging.

The above description is only a few embodiments of the present invention, and those skilled in the art can make various changes or modifications to the embodiments of the present invention according to the disclosure of the application document without departing from the spirit and scope of the present invention.
