Abstract
The utility model discloses a novel belt speed detection and alarm device which comprises a belt speed detector and a PLC (programmable logic controller). The belt speed detector comprises a speed detection wheel and a speed detection encoder, an input shaft of the speed detection encoder is fixedly connected with a central axle of the speed detection wheel coaxially, and the speed detection wheel is arranged on a return belt close to a belt driving wheel. The speed detection encoder is connected with the PLC and sends rotation speed data to the belt. A belt driving motor is connected with the PLC and sends rotation speed data to the PLC. The novel belt speed detection and alarm device is convenient to maintain, reliability in speed protection of coal conveying belts is improved, and the service life of the belt speed detector is prolonged.
Description
Technical field:
The utility model relates to a kind of novel belt speed and detects and warning device, belongs to Coal Transport equipment.
Background technology:
Existing belt speed protection major part is employed in welding one paster on the circumference of driven cylinder side; The speed detector is fixed near the driven roll circumference; Cylinder whenever circles; The speed detector detects once iron plate, through adjustment to speed detector precision, on principle, can prevent like this belt drives end skid-motor idle running or belt throw switch.Mode with the belt speed detector can skid at the belt drives end on the principle-and many realizations of in time reporting to the police when motor idle running or belt throw switch stop the motor operation automatically.But the least significant end that generally belongs to belt at driven cylinder place; In belt operation and flushing process, have a large amount of black waters like this and flow to the belt driven end, have part to fall on the speed measuring instrument unavoidably, stick with paste meter probe or detect iron plate; Make the protection malfunction, the belt mistake is jumped; In the belt operational process, dust is bigger simultaneously, at any time belt is carried out flushing work because the flushing personnel lack understanding to thermal control equipment so establish the professional, and a large amount of water slug speed measuring instruments are so just arranged, and influences accuracy of instrument and life-span; Speed measuring device is installed on strap end and near cylinder, maintenance is very inconvenient.
The utility model content:
The purpose of the utility model is that a kind of easy access is provided, improves coal conveyer belt speed protection reliability and prolongs the novel belt speed in measurement mechanism life-span to detect and warning device.
The utility model is implemented by following technical scheme: novel belt speed detects and warning device; It comprises belt speed measuring device, PLC; Said belt speed measuring device comprises fifth wheel, speed measuring coder, and the input shaft of said speed measuring coder is fixedly connected with the spigot shaft coaxle of said fifth wheel, on the return belt near the belt drives wheel, is provided with said fifth wheel; Said speed measuring coder is connected with said PLC, sends the rotary speed data of belt to said PLC; The belt drives motor is connected with said PLC, sends said belt drives rotating speed of motor data to said PLC.
The advantage of the utility model: the novel belt speed in easy access, raising coal conveyer belt speed protection reliability and prolongation measurement mechanism life-span detects and warning device.
Description of drawings:
Fig. 1 is the overall schematic of the utility model.
Fig. 2 is the scheme of installation of fifth wheel.
Belt speed measuring device 1, PLC2, fifth wheel 3, speed measuring coder 4, fifth wheel central shaft 5, belt drives wheel 6, belt drives motor 7.
Embodiment:
Novel belt speed detects and warning device; It comprises belt speed measuring device 1, PLC2; Belt speed measuring device 1 comprises fifth wheel 3, speed measuring coder 4, and the input shaft of speed measuring coder 4 and fifth wheel central shaft 5 coaxial fixed connections are provided with fifth wheel 3 on the return belt 7 near belt drives wheel 6; Speed measuring coder 4 is connected with PLC2, sends the rotary speed data of belt to PLC2; Belt drives motor 8 is connected with PLC2, sends the rotary speed data of belt drives motor 7 to PLC2.
Principle of work: speed measuring coder 4 is coaxial with fifth wheel 3; When belt 7 operations; Because friction force with belt 7 motions, is moved thereby speed measuring coder 4 is also moved simultaneously, scrambler work this moment produces pulse signal and delivers to PLC2 fifth wheel 3 between belt 7; PLC2 calculates belt speed, relatively sends the signal that skids with belt low speed setting value then.
