Shown in Figure 2, the utility model provides a kind of embodiment of deviation-resisting device for belts of bucket-wheel stacker reclaimer, described bucket-wheel stacker reclaimer comprises deflector chute 1, described deviation-resisting device for belts comprises control device, checkout gear 2 and for driving deflector chute 1 to rotate to change the drive unit 3 of deflector chute 1 and horizontal direction angle, described checkout gear 2 comprises for measuring belt side to the detecting element 21 of himself distance and using and the comparator 22 of more described detecting element 21 to actual range between belt side and detecting element 21 to initial distance size between belt side, described detecting element 21 is electrically connected with described comparator 22, described comparator 22 is electrically connected with described control device, described drive unit 3 is electrically connected with described control device.
A kind of deviation-resisting device for belts of bucket-wheel stacker reclaimer is proposed in the present embodiment, during mainly to belt deviation in bucket-wheel stacker reclaimer to the belt operation of rectifying a deviation, concrete, bucket-wheel stacker reclaimer in the present embodiment mainly includes deflector chute 1, be arranged on the striker plate 4 of deflector chute 1 below, deflector chute 1 is connected by rotating shaft 5 with one end of striker plate 4, and deflector chute 1 can 5 rotate around the shaft up and down, deflector chute 1 rotates and has changed accordingly the angle of deflector chute 1 with horizontal direction, below deflector chute 1, be provided with impact idler group 6, belt is arranged in impact idler group 6, material is introduced in deflector chute 1, then drop on the arc belt of below setting by the striker plate 4 of below.
Know that by analysis bucket-wheel stacker reclaimer is in the time carrying out work, material stream is deposited in a side of camber shape belt after the deflector chute 1 of bucket wheel falls, material stream deviation of gravity center Belt Centre, if now establishing stockpile gravity is vertically downward Fz, Fz can be decomposed into two orthogonal component as shown in Figure 1, that is: perpendicular to the component Fz2 of belt cambered surface with along the component Fz1 of cambered surface tangential direction, Fz1 can form thrust to belt, makes it transverse shifting and causes belt deviation. in moving process, stockpile center of gravity is constantly to Belt Centre convergence, and Fz1 also diminishes gradually and levels off to 0, meanwhile, the belt of sideslip can produce two power and Fz1 contends with. first power be because: it is increasing that belt departs from side institute tension stress, and be greater than inner side tension, can produce one gradually increase centripetal elastic force, second power: departed from the belt of Belt Centre from gravity, produced a component along camber line tangential direction. if belt deviation is serious, depart from the push and block that side is subject to other device and will produce the 3rd power, establishing these 3 power sums is that F closes, when these 3 power sum F close while balancing each other with Fz1, belt just stops transverse shifting. because the position of stockpile on belt generally do not change, Fz1 exists all the time, so in the situation that not taking satisfactory after correcting, belt can keep sideslip operation always. the existence of simultaneously closing due to F, stockpile center of gravity levels off to Belt Centre all the time and can not overlap. belt feeder moves and very easily causes material unrestrained under this operating mode. belt feeder sideslip reason mainly contains and causes that because get material density, viscosity differences discharging point changes, and causes belt bearing capacity change, thereby cause belt deviation phenomenon because discharging point changes. for this belt deviation phenomenon causing because of the variation of material blanking point, show that by analysis the angle that changes deflector chute 1 and horizontal plane for the change of discharging point position clearly, has good prevention effect to the sideslip of belt simultaneously. deviation-resisting device for belts in the present embodiment, main by changing the blanking position of discharging point, make the center of discharging point in belt, realize the correction to belt deviation, mainly include control device, checkout gear 2 and drive unit 3, control device is used for controlling checkout gear 2 and drive unit 3, realize the control to whole system, whether checkout gear 2 there is sideslip mainly for detection of belt in running, drive unit 3 is mainly used in driving deflector chute 1 to rotate, and then the angle of change deflector chute 1 and horizontal direction, realize the change to discharging point position, and then the correction of realization to belt deviation. when work, by measuring cell 21, belt side is detected to the distance of measuring cell 21 self, the measuring cell detecting 21 and the distance of belt side are fed back in the comparator 22 being electrically connected with measuring cell 21, comparator 22 can receive from the signal in detecting element 21, in comparator 22, store from measuring cell 21 and transmit the initial distance value of next measuring cell 21 to belt side, by the belt side in belt work running is compared to distance value and the initial distance value of measuring cell 21, correspondence is judged belt whether sideslip is occurred, in the time that running deviation value reaches the permissible value of setting, comparator 22 can provide an actuating signal, allow drive unit 3 move, deflector chute 1 is rotated a certain angle around rotating shaft 5, the discharging point of material from deflector chute 1 falls changed, allow the discharging point of material level off to Belt Centre position, thereby change the side force of material to belt, reach anti-deviation effect.
Further, described drive unit 3 is hinged with wherein one end of described deflector chute 1, and described drive unit 3 is hydraulic push rod, jack or air-leg. Drive unit 3 can knee-action, in the time of action, can drive accordingly deflector chute 1 to move up and down, and then changes deflector chute 1 and horizontal direction angle, realizes the effect of the change to discharging point position.
Further, described bucket-wheel stacker reclaimer also comprises the impact idler group 6 of putting below deflector chute 1, described impact idler group 6 is provided with 2 groups, be symmetricly set on the below of described belt both sides, described detecting element 21 is provided with 2, be symmetricly set in the impact idler group 6 of both sides, described detecting element 21 is photoelectric sensor or displacement transducer.
Preferably, in the present embodiment, detecting element 21 arranges 2, and be symmetricly set in the impact idler group 6 of belt both sides, whether left side and the right side of detection belt that can be corresponding respectively all there is deviation phenomenon, when one of them is during due to malfunction and failure, another still can move, thereby realizes intelligence correction, guarantees the stable operation of system. Meanwhile, if do not receive any signal in comparator 22, illustrate that two measuring cells 21 all break down, can provide an alarm signal this time, remind operating personnel's maintenance.
Be S0 if establish measuring cell 21 to any the initial distance on the two sides of belt, if the distance value that in work, right flank measuring cell 21 detects is S2, the distance value that left surface measuring cell 21 detects is S1, if receiver 22 is judged the signal that S1 is greater than or equal to S0 and is derived from left side, or the signal that S2 is less than S0 derives from right side, belt sideslip is to the left described, on the contrary belt deflection to the right.
Preferably, described comparator 22 is arranged on described deflector chute 1.
Further, described deviation-resisting device for belts also comprises that one for the feedback device to control device by correction result feedback.
The above, it is only preferred embodiment of the present utility model, be not the restriction of the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations. But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
