Description
Technical Field
The utility model relates to a belt conveyor, in particular to a deviation rectifying and adjusting device for a belt conveyor, which is arranged in a pair way on the large-scale belt conveyor.
Background
Belt conveyors, particularly for metallurgy, mines, power plants and applications requiring large material transport, are commonly used for transportation. At this time, the belt conveyor is in high-speed, high-load and long-distance (up to more than 1 km) running condition, and because of the influence of loaded large-scale materials, the situations of belt deviation, material scattering along the line of the belt conveyor and the like frequently occur in the field in the conveying process, so that the conveying efficiency is influenced, pollution is formed to the environment, and the civilized production is influenced. Meanwhile, the belt deviation of the belt conveyor can shorten the service life of the belt conveyor, increase the maintenance frequency and improve the use cost.
Therefore, heretofore, a deviation rectifying and adjusting device for the belt deviation of a large-scale belt conveyor has been developed in the industry to automatically adjust and rectify the belt deviation.
At present, a connecting rod mechanism is mainly adopted for a deviation rectifying and adjusting device used on a high-speed belt or a belt conveyor, and the structure is as follows: the middle cross beam of the connecting rod mechanism is fixed, and the two ends of the middle cross beam are provided with deflection adjusting rollers for realizing the effect of aligning.
For example, a barrel self-swinging type groove-shaped aligning carrier roller can be used for aligning a belt conveyor, if a conveying belt is deviated, the friction force relative to the gravity center to which side is deviated is increased, under the action of the friction force, one end with large friction force swings towards the running direction of the conveying belt, and the function of automatic swing can adjust the belt to the middle running route. But the deviation rectifying range and effect are limited, so that the conveying efficiency is affected, and the situation that materials are scattered along the line of the belt conveyor is serious, so that pollution is formed to the environment, and the civilized production is affected.
For another example, the 2 conical rollers of the conical aligning carrier roller are respectively arranged on the respective revolving racks, when the conical rollers are arranged, the big end is arranged on the inner side, the small end is arranged on the outer side, and the 2 revolving racks realize synchronous rotation through the connecting rod mechanism, and the cross beam is directly connected on the middle rack. Since the diameters of both ends of the tapered roller are different, the same angular velocity of the roller generates different linear velocities in the tapered diameter when the roller rotates. According to the relationship between the angular velocity and the linear velocity, the linear velocity is proportional to the radius in the case where the angular velocity is constant. Therefore, on the tapered roller, the large end linear velocity is large, the small end linear velocity is small, and there is a linear velocity difference on one roller. When the conveyer belt is deviated, the conveyer belt is contacted with the small end of the roller, and an extra resistance is generated between the roller and the conveyer belt due to the small linear speed, so that the revolving frame is driven to rotate around the revolving shaft by a certain angle, a carrier roller group is formed to apply transverse thrust to the belt, and the deviated belt is promoted to return to the original position, thereby realizing automatic deviation correction of the deviation belt.
Now, more automatic core-adjusting roller supports are adopted, as shown in fig. 3, a base fixed on a truss of a belt conveyor is arranged at the bottom of the carrier roller support, a movable disc is arranged on the base, the movable disc and a pin form a transmission mechanism to horizontally rotate at fixed points, and two ends of the disc are respectively provided with a rotation limiting mechanism. The support adopts the principle of 'no running before and after running', namely, the side roller is touched when the belt is deviated, the whole support is driven to rotate, and the deviation is corrected.
However, in practical application, the aligning and offset idler has very limited deviation correcting effect due to the fact that the lateral friction force generated in the rotation operation in the horizontal direction is very limited, and the effect is poorer for a conveying belt with larger fluctuation of materials in operation. Secondly, due to the restriction of working conditions such as site dust, rainwater and materials, the flexibility of the bracket can be greatly influenced, so that the deviation correcting effect of the bracket is greatly influenced.
The above is applicable to a conveyor belt with a small deviation range. When the deviation amount is small, the rotation angle of the carrier roller at the deviation side is small, and the transverse thrust generated on the conveying belt is also small; when the deflection amount is large, the rotating angle of the carrier roller at the deflection side is large, and the transverse thrust generated on the conveying belt is also large. Thus, the automatic adjustment of different running deflection amounts is realized.
In addition, the main shortcoming of the conventional aligning roller is that the degree of freedom is limited insufficiently, the degree of freedom limited by the connecting rod mechanism is limited to be fixed in the center, and the principle that the belt conveyor is very large in homeotropic inertia force and is difficult to rectify through the connecting rod automatic motion of the aligning roller is considered, so that the effect is not great in practical application, conversely, the belt conveyor is excessively flexible due to the fact that the excessive flexibility is added to the belt conveyor, the problem is more likely to occur when the material taking amount is large and small, meanwhile, the problem that the belt cannot touch one side carrier roller easily occurs in the belt deviation process, and the daily deviation rectifying and adjusting failure is caused.
Therefore, the problem in the past is that its rectifying effect is very limited, and bearing roller adjusting device structure is unreasonable, and the stability of belt feeder operation is not enough, and the scattering material along the belt feeder can't ensure that the environment is clean and tidy, is difficult to be applicable to large-scale band conveyer under the running conditions of high-speed, high load (large-scale material) and long distance (can reach more than 1 km).
