Description
Technical field
The utility model relates to a kind of slipping of the belt monitoring device.
Background technology
Belt is carried in the process of convey materials, and most of climbing under the situation of heavy load, all may be skidded, in case skid, material input end generation solid accumulation, the material mouth can not failed material, even rubs belt generation equipment breakdown or industrial accident.Whether belt skidded very important for the belt safe transport when monitoring belt was carried, existing slipping of the belt monitoring device mainly is the device that skids, it has a little flower wheel and inertia relay, flower wheel contacts with belt, after the belt starting, utilize the friction between belt and the flower wheel to drive the flower wheel rotation.Inertia relay is installed on the axle of flower wheel, and when belt speed reached certain, flower wheel drove the closing of contact of inertia relay, and output signal confirms that belt does not skid, and when belt starting inertia relay does not have output signal, slipping of the belt has been described.The weak point of this slipping of the belt monitoring device is the mechanical movement life-span of flower wheel and the service life that the relay bearing has limited the device that skids, general operation 2000 hours, increased over-the-road expense, and installation is very inconvenient, during installation, the people gets between belt two-layer up and down, work is dangerous, and labour intensity is higher, and the set-up time is long, general 3 hours, influence was produced.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing slipping of the belt monitoring device, the utility model provides a kind of reliable operation, slipping of the belt monitoring device easy for installation.
Design of the present utility model is the driven member at band conveyor---driven cylinder or belt are installed small iron plate, preferably at driven cylinder small iron plate are installed.On driven cylinder, small iron plate is installed, one to four of general installation, if the diameter of driven cylinder is very big, the small iron plate of An Zhuaning is just more than a slice so, the position that is installed near switch near driven cylinder, the position that faces toward small iron plate process on the driven cylinder near the signal input part of switch, when the driven cylinder of belt drive rotates, small iron plate rotates and near near switch, whenever small iron plate near near switch the time, near switch conduction once, and export an impulse singla, impulse singla is defeated by industrial control computer, shows by industrial control computer whether belt skids.Also can a little iron sheet evenly be installed at a certain distance at belt, its effect is with to be installed in driven cylinder identical.
The utility model comprises signal output device and the driven member that is driven by drive roll, it is characterized in that: said signal output device is near switch, at driven member small iron plate is installed, can detect signal in order to allow near switch, the length of small iron plate is not less than 50 millimeters, be installed in the position of close driven member near switch, the position that faces toward small iron plate process in the driven member rotation process near the signal input part of switch, near the signal input part of switch to the shortest distance of small iron plate less than near switch farthest near distance, promptly can receive the ultimate range of small iron plate signal near the signal input part of switch, generally this distance is not more than 8 millimeters.
Above-mentioned slipping of the belt monitoring device, it is characterized in that: said driven member is driven cylinder, small iron plate is installed in the position of the same circumference on the position of same radius of end face of driven cylinder or the face of cylinder, at driven cylinder one to four small iron plate is installed, near the signal input part of switch distance apart from driven cylinder, greater than near switch farthest near distance, can avoid the driven cylinder of steel to interference like this near switch.
Above-mentioned slipping of the belt monitoring device is characterized in that: said driven member is a belt, and iron plate is along vertical rectangular distribution of belt, and the distance between small iron plate and the small iron plate is 2 meters-4 meters.
This slipping of the belt monitoring device adopts the signal that receives the belt operation near switch as signal output device, and this signal is converted to electric signal is defeated by and the industrial control computer that connects near switch, when driven cylinder rotates, whenever the close signal input part of a small iron plate near switch, once export an impulse singla near switch conduction, this impulse singla is delivered on the input template of industrial control computer.Near switch conduction once, illustrate that driven cylinder has rotated an angle, this angle is 360 °/N, and N is the number that is installed in the iron plate in driven one week of cylinder.When do not have near switch signal or often between when output signal is arranged, then think slipping of the belt.This principle of work has contained the situation of the fault that has near switch itself or circuit broken string, also can the getting rid of false signal, and reliable operation.When near switch output signal, industrial control computer receives an impulse singla, and belt normally moves, and impulse singla just constantly is defeated by industrial control computer.When do not have pulsed current signal or impulse singla is arranged always, can conclude that then slipping of the belt or belt are not activated.When belt began to start, industrial control computer was set delay time as 5 seconds, did not promptly measure the impulse singla near switch after belt starts in 5 seconds, can confirm slipping of the belt, and utilizing for 5 seconds is in order to escape the startup crawl time of belt.Near the long-time output pulse signal of switch, then may be that iron plate is just stopping near the switch place or is being out of order near switch.The impulse singla of output also can be given programmable controller (PLC), and by PLC control output relay and annunciator, annunciator sends alerting signal and by this relay outage, drive roll stops operating.The utility model is used near switch and is replaced the device that skids, and used element cost is low, has reduced working strength of workers during installation, and waiting time is short, and operating safety factor is higher.
