Referring to fig. 1 and 2, a description will now be given of a belt drive anti-galloping device for a belt conveyor. The top belt driving anti-galloping device of the downward belt conveyor comprises a belt conveyor main body with a slope changing area 100 in the middle, wherein the belt conveyor main body is provided with an upper belt area 200 and a lower belt area 300, the upper belt area 200 and the lower belt area 300 are respectively arranged on the upper side and the lower side of the slope changing area 100, the end part of the upper belt area 200 is provided with a turning-back end 210, the end part of the lower belt area 300 is provided with an unloading end 310, the upper belt area 200 is provided with a top belt provided with a middle driving mechanism 220, and the bottom belt of the lower belt area 300 is provided with a belt storage bin 320; the middle driving mechanism 220 includes a driving frame 221, a middle driving roller 222, a first unloading roller 223 and a first folding roller 224, wherein the middle driving roller 222, the first unloading roller 223 and the first folding roller 224 are all mounted on the driving frame 221, the middle driving roller 222 is located in the middle of the driving frame 221, the first folding roller 224 is located at the upper portion of the driving frame 221, and the first folding roller 224 is located at the lower portion of the driving frame 221.
Compared with the prior art, the top belt driving anti-galloping device of the down conveyor provided by the invention has the advantages that the middle driving mechanism 220 is arranged on the top belt of the upper belt area 200 of the main body of the belt conveyor, and the middle driving roller 222, the first unloading roller 223 and the first turning roller 224 are arranged on the driving frame 221 of the middle driving mechanism 220. The top belt of the upper belt zone 200 passes through the first unloading roller 223 above the driving frame 221 and then enters the middle driving roller 222, and passes through the first turning roller 224 below the driving frame 221 and then passes around the lower part of the middle driving roller 222, so as to form a downward conveying belt for carrying coal, and the driving mode of the main body of the belt conveyor is top belt driving. The running resistance of the main body of the belt conveyor is changed in a top belt driving mode, the belt is folded back for the first time through the first unloading roller 223, is folded back for the second time through the middle driving roller 222, is folded back for the third time through the first folding roller 224 again, and is folded back and wound with the plurality of rollers to form a larger wrap angle, so that the friction force of the belt is increased, the component force of the gravity of raw coal in the running direction can be effectively balanced through the friction force formed by the plurality of rollers and the belt, and the phenomenon of galloping is directly avoided.
Specifically, after the top belt of the upper belt zone 200 passes through the middle driving roller 222 and the first turning roller 224, the lower belt provides a larger pressure to the middle driving roller 222, so that the friction between the belt and the middle driving roller 222 is improved, and the component force of the gravity of the raw coal in the running direction is effectively balanced. Meanwhile, in the process of downward conveying of the belt, after the top belt is folded back to form the bottom belt through the first unloading roller 223, the bottom belt has longer running distance, is influenced by running resistance and gravity, has larger stretching amount, is more beneficial to keeping uniform motion with the top belt, and can not generate a belt accumulation phenomenon after the first unloading roller 223 even if the speed of the top belt is increased. The top belt driving anti-galloping device of the lower belt conveyor provided by the invention can solve the galloping phenomenon of the lower belt conveyor, reduce the risks of equipment damage and personnel injury, and ensure the production efficiency.
In some embodiments, referring to fig. 3, the unloading end 310 is provided with a head unloading device for folding back the top belt of the lower belt section 300 into a bottom belt and guiding it horizontally to the belt magazine 320.
Specifically, the machine head unloading device includes a machine head unloading frame 311, an unloading folding roller 312, a first guide roller 313 and a second guide roller 314, the unloading folding roller 312 is located at one end of the upper portion of the machine head unloading frame 311 far away from the tape storage bin 320, the second guide roller 314 is located at one end of the lower portion of the machine head unloading frame 311 near the tape storage bin 320, and the first guide roller 313 is located at the middle portion of the machine head unloading frame 311 and between the unloading folding roller 312 and the second guide roller 314.
The belt guided out by the first guide roller 313 and the second guide roller 314 after the unloading turning roller 312 can be smoothly transferred to the belt storage bin 320, so that the running resistance of the belt is reduced, and the galloping phenomenon is avoided.
Referring to fig. 1, the tape storage bin 320 includes a plurality of tape storage roller sets disposed from top to bottom, each tape storage roller set has two tape storage roller sets 321 arranged at intervals from left to right, and at least one tape storage roller 321 in the tape storage roller set at the bottom is at the same height as the second guide roller 314. Wherein, there is a height difference between two belt folding rollers 321 located in the same belt folding roller group, and the distance between two belt folding rollers 321 in the same belt folding roller group gradually decreases from bottom to top.
Specifically, the number of the plurality of tape folding rollers 321 is plural and is an even number of four or more, the tape folding rollers 321 form a group in pairs, and a plurality of tape storage roller groups are formed from top to bottom. The two tape turning rollers 321 of the same group have a height difference, and among the two tape turning rollers 321 of the bottom layer tape roller group, the tape turning roller 321 far away from the head unloading device can smoothly guide the belt from the second guide roller 314 to the tape storage bin 320. The belt is then folded back upwardly in the belt storage bin 320 until it reaches the uppermost portion of the belt storage bin 320, and finally is guided out of the belt storage bin 320, through the ramp region 100, and into the upper belt region 200.
Referring to fig. 1, the number of the middle driving rollers 222 is two, and the two middle driving rollers 222 are laterally arranged at intervals in sequence. The top belt of the upper belt section 200 is wound from the distal middle driving roller 222 to the proximal middle driving roller 222 in a staggered manner, so that the top belt and the two middle driving rollers 222 have more contact area, and the friction force between the top belt and the two middle driving rollers 222 is increased. That is, in the case of having two middle driving rollers 222 in the process of performing the second turn-back based on the belt passing through the middle driving roller 222, the turn-back is performed twice at the middle driving roller 222, thereby forming the four turn-back in the top belt driving manner, which is more advantageous for avoiding the galloping phenomenon.
In some embodiments, the two middle driving rollers 222 are in transmission connection with a permanent magnet synchronous motor, and a frequency converter with a constant torque adjusting function is arranged in the permanent magnet synchronous motor.
The mining high-quality frequency converter core specially designed for the permanent magnet synchronous motor is adopted, the heavy load working condition of a constant torque load can be met, and a large starting torque is provided for the load. The special model is STYB permanent magnet synchronous motor-driven roller matched with BPB1-110/660K type mining flameproof alternating current frequency converter as the driving design, provides stable running speed for the belt conveyor, runs synchronously with the belt, eliminates mutual sliding between the middle driving roller 222 and the belt, and realizes automatic adjustment. The frequency converter can be well adapted to the influence caused by unbalanced power grid voltage, and has the function of energy feedback of current bidirectional flow.
Specifically, the automatic torque boosting function is provided during low frequency operation. When the output current of the frequency converter exceeds a certain threshold value, the frequency converter automatically adjusts the output frequency to the normal running speed after adjustable delay. Thus, the central drive roller 222 is controlled to maintain synchronous operation with the belt. And the two middle driving rollers 222 of the belt conveyor main body can realize the functions of current balance and speed synchronization control, so that the condition of friction resistance reduction caused by asynchronous transmission of the two middle driving rollers 222 can be effectively reduced, and the galloping phenomenon caused by skidding is avoided.
According to the top belt driving anti-galloping device of the downward belt conveyor, through the layout mode and the belt winding mode of the driving part of the main body of the belt conveyor and the design of the selecting and unloading device of the driving device, various weak links which possibly influence galloping of the belt conveyor are eliminated, various links of the belt conveyor are effectively integrated, galloping phenomena of the belt conveyor are restrained, damage of equipment and a roadway and personal safety accidents are avoided, production efficiency phenomena influenced by galloping are eliminated, continuous transportation of the downward belt conveyor is realized, coal yield is ensured, and maintenance cost of maintenance personnel and equipment is reduced.
The belt lifting device is mainly used for solving the potential safety hazard of belt lifting of the lower conveying belt conveyor aiming at the belt conveying lines with large gradient, long line and large coal quantity, realizes safe and efficient operation of the lower conveying belt conveyor, and has great significance for improving efficiency and safety of the belt conveyor.
