Abstract
The utility model discloses a longitudinally-tearing preventing device of a belt type conveyor, and belongs to the field of belt type conveyor detection devices. The longitudinally-tearing preventing device is mainly used for protecting rubber belts of the belt type conveyors, and comprises a PLC, a detection device and an execution mechanism. The detection device and the execution mechanism are connected with the PLC. The execution mechanism is connected with a drive motor of a roller, and the detection device comprises an infrared detection device and a closed loop circuit. The infrared detection device and the closed loop circuit are both arranged on a machine frame cross beam below the belt type conveyor. The closed loop circuit is connected under normal conditions, a belt is pierced when being damaged by external force, meanwhile, the closed loop circuit is damaged, the infrared detection device transmits coal leakage signals to the PLC, if the infrared detection device does not work, when the PLC detects that the closed loop circuit is damaged, the signals are output to the execution mechanism to stop operation of the roller motor, and the belt is prevented from being further damaged. The infrared detection device is used in cooperation with the closed loop circuit, and detection reliability is further improved.
Description
Technical field
The utility model relates to the anti-vertical ripping device of a kind of belt conveyer, belongs to belt conveying machine detecting device.Be mainly used in the adhesive tape protection of belt conveyer.
Background technology
Belt feeder longitudinal tear is mainly because during working surface production, and the metal objects such as anchor pole are sneaked into coal flow system, causes tearing of belt, and some are vertical, and to tear detecting device misoperation more, and what impact was produced normally carries out, and even causes industrial accident.At present, the anti-vertical ripping device of common belt conveyor, generally adopts infrared detection to leak the method for coal, and detection accuracy is poor, as vertical tearing detected accurately not in time, may expansion accident, and cause larger economic loss, affect the normal production of mine.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of belt conveyer anti-vertical ripping device.
The utility model is realized with following technical scheme: the anti-vertical ripping device of a kind of belt conveyer, comprise PLC controller, the detecting device and the actuating unit that are connected with PLC controller, described actuating unit connects the drive motor of cylinder, described detecting device comprises infrared detecting device and C/LOOP, and infrared detecting device and C/LOOP are installed on the housiung separator below belt conveyer belt.
Principle of work is: C/LOOP is conducting under normal circumstances, in the situation that belt is subject to external force damage, belt is stung, also C/LOOP can be damaged, infrared detecting device is transferred to PLC controller by leakage coal signal simultaneously, if in the malfunctioning situation of infrared detecting device, when PLC detects C/LOOP when damaged, output signal to actuating unit, stop the running of rotary drum electrical motor, prevent from further injuring belt.Infrared detection mechanism and C/LOOP testing agency are used in conjunction with, and have further improved the reliability detecting.
Good effect of the present utility model is: the safe operation of protection belt feeder, and installation, convenient disassembly, reliability is high.
Accompanying drawing explanation
Fig. 1 is belt conveyer structural representation;
Fig. 2 is the utility model structural representation.
In figure: 1, cylinder, 2, carrying roller, 3, belt, 4, motor, 5, actuating unit, 6, infrared detecting device, 7, C/LOOP, 8, PLC controller.
The specific embodiment
As shown in Figure 1, belt conveyer is by cylinder 1, carrying roller 2, and belt 3, motor 4, actuating unit 5, infrared detecting device 6 forms.
As shown in Figure 2, the anti-vertical ripping device of belt conveyer comprises PLC controller 8, the detecting device and the actuating unit that are connected with PLC controller, described actuating unit 5 connects the drive motor 4 of cylinder, detecting device forms double check by infrared detecting device 6 and C/LOOP 7, is installed on the housiung separator below belt conveyer belt.The present embodiment C/LOOP 7 is back traverse, arranged in a crossed manner below belt with belt.Actuating unit 5 is relay or switch.
C/LOOP is conducting under normal circumstances; in the situation that belt is subject to external force damage; belt is stung; simultaneously also by back traverse tear fracture; the information that back traverse disconnects sends PLC controller to; infrared detecting device 6 is transferred to PLC controller by leakage coal signal simultaneously, forms duplicate protection, has further improved the reliability detecting.
