Description

Technical Field

[0001] The invention relates to the technical field of conveying materials with a belt conveyor, and in particular to a belt conveyor with an automatic deviation correction function and a deviation correction method. Background Art

[0002] The driving wheel of conventional metallurgical and mining belt conveyors is driven by an electric motor, and the driven wheel is generally set at the feeding port. The driving wheel carries the material and drives the belt conveyor to run from the driven wheel to the driving wheel. The belt conveyor has different lengths according to different production processes. The driving wheel and the driven wheel span the two ends of the belt conveyor, which is several meters or even thousands of meters long.

[0003] When the belt conveyor is newly installed or overhauled, it is necessary to perform no-load and loaded adjustments to prevent the belt conveyor from running off course. Insufficient deviation correction performance will cause wear on the side of the belt and the frame, and even cause the belt to roll over, affecting the life and stability of the belt conveyor.

[0004] There are many factors that affect the deviation of the belt conveyor, such as the deviation of the belt caused by the support frame part not being on the center line when the belt conveyor is installed. The reason is that the center is not adjusted properly when the belt conveyor is installed, resulting in uneven force on the belt conveyor, causing wear, which not only reduces the quality of use, but also easily causes deviation. In severe cases, it can cause the belt to break. There is also a kind of deviation that even if the belt conveyor has been adjusted to the best working state in the no-load state, the uneven loading of materials on the belt conveyor will still cause the belt conveyor to deviate. The vibration of the belt conveyor during operation causes deviation. The belt conveyor will inevitably vibrate during long-distance operation, causing the belt conveyor to deviate, etc. Summary of the invention

[0005] In view of this, on one hand, the present invention proposes a belt conveyor with an automatic deviation correction function, comprising a support frame, a driving wheel, a driven wheel, a conveyor belt and an automatic deviation correction system; the driving wheel and the driven wheel are respectively arranged at the front end and the rear end of the support frame, the driving wheel shaft is rotatably connected to the support frame, the driven wheel shaft is rotatably connected to the support frame within a preset width parameter range, the conveyor belt is sleeved on the driving wheel and the driven wheel, and drives the driven wheel to rotate by friction as the driving wheel rotates, the automatic deviation correction system comprises a pressure detection system and an adjustment system, the pressure detection system is used to detect the pressure of the driving wheel and the driven wheel, and then transmits the pressure signal to the adjustment system, so as to perform deviation correction adjustment on the position of the driven wheel.

[0006] Furthermore, the pressure detection system includes a driving wheel pressure detection device and a driven wheel pressure detection device. The driving wheel pressure detection device is arranged at one side of the driving wheel to measure the surface pressure of the driving wheel roller. The driven wheel pressure detection device is arranged at one side of the driven wheel to measure the surface pressure of the driven wheel roller. The pressure signals of the two detection devices are transmitted to the adjustment system, and then the driven wheel is corrected and adjusted.

[0007] Furthermore, the adjustment system includes two adjusters, which are arranged corresponding to the two sides of the driven wheel, and the two adjusters adjust the driven wheel by telescoping.

[0008] Furthermore, the regulator is an electric adjusting screw rod, and the two electric adjusting screw rods drive the bearings on both sides of the driven wheel to perform telescopic adjustment.

[0009] Furthermore, a guide roller groove is provided on the support frame corresponding to the driven wheel, so as to limit the movement trajectory of the driven wheel.

[0010] Furthermore, lubricating grease is applied in the guide roller groove.

It also liberates the labor and cost of manual mechanical deviation adjustment. The automatic deviation correction device of the belt conveyor of the present invention is maintenance-free during production and operation, which liberates manpower, prolongs the service life of the belt conveyor, and improves production and transportation efficiency and stability.

After the deviation correction test is completed, it enters normal operation.

[0013] Furthermore, the deviation states include three types, namely: the driving wheel conveyor belt deviates from the center line causing the driving wheel to deviate, the driven wheel conveyor belt deviates from the center line causing the driven wheel to deviate, and the conveyor belt is unevenly loaded and runs to the deviation state.

[0014] Furthermore, during the assembly process of the components, lubricating grease is applied to the guide roller groove.

[0015] Furthermore, before the components are assembled, the width of the conveyor belt is determined in advance, and then the widths of the driving wheel and the driven wheel are determined according to the conveyor belt.
