By adopting the technical scheme, the fault overhaul problem of the belt conveyor is facilitated; once the problem disappears, a fault point alarming device sends out an alarm, so that fault incident places are quickly found and the problem is solved readily; in addition, the waste of human resources due to shutdown inspection is avoided; once a safety control device has faults in the normal operation of equipment, the faults can be immediately founded, so that the influence to the production due to long-time shutdown is avoided.
Description
Technical field
The invention belongs to the technical field of the equipment of industrial product, relate to the technology of belt transporter, more particularly, the present invention relates to a kind of control system for belt conveyor.
Background technology
Below in conjunction with the Fig. 1 in this Figure of description and Fig. 2, prior art is analyzed:
Figure 2 shows that the detailed content of detecting signal unit 14 in Fig. 1, the code name that wherein LS1～LS10 is 10 stay cord limit switches 1, the code name that FP1～FP4 is 4 anti-deviation limit switches 2, the code name that FS is anti-tear protection switch 3.All get its normally closed contact, power supply is used to the back control element of control system for belt conveyor to the B end from the A end through the normally closed point of LS1～LS10, FP1～FP4, FS successively again.
As shown in Figure 2, according to security regulations, the safe operation of material band conveyor, must there be stay cord limit switch 1 the belt transporter both sides as protection.Also need anti-deviation limit switch 2 and anti-tear protection switch 3 as protection.Described stay cord limit switch 1, anti-deviation limit switch 2 and anti-tear protection switch 3 all adopt normally closed interlock to be connected in series, and form detecting signal unit 14.Described detecting signal unit 14 is connected on A in the control loop of the described belt transporter of Fig. 1, B end by the A in Fig. 2, B end.
If a certain switch picked up signal and disconnecting, control system for belt conveyor makes outage.
But especially, under severe production environment, the life-span of stay cord limit switch 1, anti-deviation limit switch 2 and anti-tear protection switch 3 etc. is shorter; Or different because of the coefficient of expansion of climate change steel rope and belt feeder framework, cause the steel rope tension, and then cause the 1 inner contact virtual connection of stay cord limit switch; If the belt of conveyer is very long, while breaking down, the workman need to grow distance or the climbing up and down of ascending a height, and repeats in investigation trouble point, belt both sides or the hidden fault point, and its labour intensity is very large.
Because trouble point is submerged in multicomponent unit, trouble unit can't be detected in time, after et out of order, being difficult to find is the problem which goes out, can't find in time trouble point, repair very trouble, affect rhythm of production, have a strong impact on production, and expend a large amount of manpowers.
