Description

A kind of coal conveyer belts monitoring device for belt tearing
Technical field
The utility model relates to a kind of coal conveyer belts monitoring device for belt tearing, belong to coal-fired power plant's equipment state prison Survey technology field.
Background technique
Coal conveyer belts are the important subsidiary engine equipment of coal-fired power plant, and coal works storage fire coal is transported to boiler raw coal by it Storehouse, the reliability of work directly influence the safety and stability and economic benefit of generating set.The belt of coal conveyer belts is once Tearing gently leads to unit load down if discovery is not in time, heavy then cause boiler to lose all fuel and occur that unit is non-to stop thing Therefore.Therefore, the accuracy and reliability for improving the monitoring of coal conveyer belts belt tearing has great importance.
Numerous scholars were almost leather belt deviating-proof device entirely to the project that coal conveyer belts are studied in recent years, only few so far Number scholar detects or is torn to coal conveyer belts belt fracture prevention and control device and carried out design studies.Two Chinese patents and three Technical papers is directly to be carried out friction with belt using ultrasound examination or infrared detector or outer increasing detection device and connect Touching rotates synchronously to detect whether belt is broken.Above-mentioned detection device cost investment is big, installation and operation condition requires harsh, increasing Oil (gas) filling device fault point increases the drawbacks such as belt running contact abrasion, influences the safe operation of unit normal table.
Utility model content
The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and provide a kind of structure design conjunction Reason, accurate and reliable, Simple And Practical coal conveyer belts monitoring device for belt tearing, to facilitate power plant collection control operations staff real-time Monitor coal conveyor belt operating condition.
The technical scheme in the invention for solving the above technical problem is: a kind of coal conveyer belts belt tearing monitoring dress It sets, which is characterized in that including angle bar, support base, rigid strut, mechanical trip switch, contact push rod, DCS control system, skin Band driven wheel beaming roller and belt slave wheel;The belt slave wheel is mounted on belt slave wheel beaming roller, and the angle bar is fixed on On belt slave wheel beaming roller, the angle bar is adjacently positioned with belt slave wheel;The support base is fixed on the axis of angle bar side It puts on, the mechanical trip switch is fixed by rigid strut with support base, and the contact push rod is located at mechanical trip switch On, the angle bar is adjacent with rigid strut and does not contact;The mechanical trip switch is connect with DCS control system.Mechanical trip Switch contact signal access DCS control system carries out delay logical operation process and configuration belt tearing alarming logic.
Furthermore, the logic that coal conveyer belts belt tearing sound-light alarm is increased in the DCS control system is returned Road interface, to prompt operations staff to find belt tearing exception in time.Mechanical trip switch contact signal is directly accessed DCS control System processed after the logical operation process that is delayed, introduces DCS sound-light alarm logic interfacing, so that operations staff can monitor in real time Belt feeder belt operating condition.
Furthermore, the angle bar is welded and fixed with belt slave wheel beaming roller, the angle bar and belt slave wheel beaming roller It is arranged vertically;When work, the angle bar is rotated synchronously as belt feeder is run with belt slave wheel, to periodically touch Stir the contact push rod of mechanical trip switch.
Furthermore, it is welded and fixed between the rigid strut and support base, the rigidity strut and support base It is arranged vertically.
Furthermore, the mechanical trip switch level is fixed on rigid strut.
When coal conveyer belts monitoring device for belt tearing is rotated according to belt, the angle bar of driven wheel coaxial synchronous rotation can week Mechanical trip switch is caused to phase property to generate by 0 to 1 rising edge pulse signal, to judge that belt is not torn.When defeated coal skin Mechanical trip switch can generate 0 or 1 lasting ordinary mail number when with machine belt tearing, perhaps belt feeder is stopped transport, and control through DCS System issues sound-light alarm and belt feeder trip protection signal after carrying out delay logical operation process.
The utility model compared with prior art, has the following advantages that and effect:
(1) the utility model structure is simple, not fetch ring border, insensitive to vibration and dust, easy to maintain;
(2) the long handle mechanical trip switch that used equipment removes can be used in mechanical trip switch, and past heritage recycle, and system is set Standby cost is small or even zero cost;Using the existing DCS control system of host, control loop information processing rate is fast, high reliablity;
(3) the utility model does not contact rotation directly with the belt of coal conveyer belts, will not wear and damage belt;
(4) after belt tearing monitoring signals enter DCS control system, the defeated coal of power plant operations staff can timely and intuitively be prompted There are belt tearing unusual service condition, and automatic trip coal conveyer belts in belt feeder, wins preciousness for more rapidly processing belt failure Opportunity.
Detailed description of the invention
Fig. 1 is the schematic block circuit diagram of coal conveyer belts monitoring device for belt tearing in the present embodiment.
Fig. 2 is the overall structure diagram of coal conveyer belts monitoring device for belt tearing in the present embodiment.
In figure: 1- angle bar;2- support base;3- rigidity strut;4- mechanical trip switch;The contact 5- push rod;6-DCS control System;7- belt slave wheel beaming roller;8- belt slave wheel.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is pair The explanation of the utility model and the utility model is not limited to following embodiment.
Embodiment.
Referring to Fig. 1 to Fig. 2, the coal conveyer belts monitoring device for belt tearing in the present embodiment includes angle bar 1, support base 2, rigid strut 3, mechanical trip switch 4, contact push rod 5, DCS control system 6, belt slave wheel beaming roller 7 and belt slave wheel 8;Belt slave wheel 8 is mounted on belt slave wheel beaming roller 7, and angle bar 1 is fixed on belt slave wheel beaming roller 7, angle bar 1 and belt Driven wheel 8 is adjacently positioned;Support base 2 is fixed on the axle sleeve of 1 side of angle bar, mechanical trip switch 4 pass through rigid strut 3 with Support base 2 is fixed, and contact push rod 5 is located on mechanical trip switch 4, and angle bar 1 is adjacent with rigid strut 3 and does not contact;It is mechanical Travel switch 4 is connect with DCS control system 6.
In the present embodiment, the logical circuit that coal conveyer belts belt tearing sound-light alarm is increased in DCS control system 6 is connect Mouthful, to prompt operations staff to find belt tearing exception in time.4 contact signal of mechanical trip switch is directly accessed DCS control System 6 introduces DCS sound-light alarm logic interfacing, so that operations staff can supervise in real time after DCS logical time delay calculation process Control belt feeder belt operating condition.
