Abstract
The utility model relates to an automatic stall protection device of a belt conveyor. The automatic stall protection device of the belt conveyor is mainly characterized in that the automatic stall protection device comprises the belt conveyor, a detection piece is fixedly arranged on a bearing face of a driven wheel of the belt conveyor and a speed measuring switch which is connected with a DCS control system is fixedly arranged at the position, 1cm away from the detection piece, outside the driven wheel. By means of the automatic stall protection device of the belt conveyor, the accidents of belt breakage and tearing caused by sliding and belt deviation and due to the fact that materials are too many so that the belt conveyor is crushed can be avoided.
Description
Technical field
The utility model relates to a kind of travelling apron stall automatic safety device, mainly refers to and utilizes DCS system and approach switch to combine to realize the device of automatically protecting after travelling apron stall.
Background technology
Travelling apron plays very important effect at the manufacturing enterprises such as modernization cement, building materials, thermoelectricity, colliery transhipment raw MAT'L.In actual production, travelling apron is because reasons such as skidding, expect multiple pressure is dead, rubber belt from deviating causes that the accident that adhesive tape breaks, tears is a lot.Especially in the situation that expect rainy season wetly, adhesive tape is broken accident and is frequently occurred, and has a strong impact on the normal production of modern enterprise.
Summary of the invention
The contriver finds that in daily working process existing travelling apron exists above-mentioned defect in use; through design improvement constantly, technical problem to be solved in the utility model is to provide a kind of travelling apron stall automatic safety device that can effectively prevent that adhesive tape from breaking, tearing.
For solving the problems of the technologies described above; technical solution adopted in the utility model is that designed travelling apron stall automatic safety device comprises travelling apron; set firmly detection lug on the follower shaft bearing surface of travelling apron, the place apart from detection lug 1cm outside flower wheel sets firmly a speed measurement switch be connected with the DCS control system.
The utility model adopts the designed travelling apron stall automatic safety device of technique scheme; owing on the follower shaft bearing surface, establishing detection lug; the operating speed of travelling apron is transferred to control system by detection lug, speed measurement switch; by control system, realize automatically protecting after travelling apron stall; thereby solved because skidding, expect that the reasons such as multiple pressure is dead, rubber belt from deviating cause the accident that adhesive tape is broken, torn, who knows the continuous reliability service of manufacturing line for the modernization large-scale cement sound assurance is provided.
The accompanying drawing explanation
Fig. 1 means the structural representation of the utility model sealing-tape machine;
The side-looking structural representation of sealing-tape machine flower wheel in Fig. 2 presentation graphs 1.
The specific embodiment
Structure below in conjunction with accompanying drawing to the utility model travelling apron stall automatic safety device illustrates.
Referring to Fig. 1; Fig. 2; the utility model travelling apron stall automatic safety device comprises driving wheel 3 and the flower wheel 2 of travelling apron 1 and travelling apron; set firmly a detection lug 4 on the bearing surface of the flower wheel 2 of travelling apron 1; outside flower wheel 2 from detection lug 4 distance for establishing an electronic speed-determination switch 5 in the place of 1cm; speed measurement switch 5 is fixed on a connecting element 6, and speed measurement switch 5 is connected with the DCS control system by corresponding lead-in wire 7.
The critical frequency adjustment of the utility model speed measurement switch 5 is to determine by the direction of the rotary screw on it (potential device), and the adjustable frequency scope is 6--150 pulse/min.When travelling apron normally moves, flower wheel 2 drives detection lug 4 and synchronously rotates, when detection lug 4 passes through speed measurement switch 5, speed measurement switch 5 just produces a pulse, when the pulse number that speed measurement switch 5 per minutes produce reaches the number of its setting in advance (this number is adjustable), show travelling apron 1 normal operation; When pulse number, during lower than setting value, the action of the alarm switch of speed measurement switch 5, deliver to stall alert signal of DCS control system.When skidding appears in belt, the rotating speed of flower wheel 2 can obviously reduce, even stall, and the pulse number that speed measurement switch 5 detects within the unit time like this will reduce, and out of reach starts the pulse count of setting, and just sends corresponding alerting signal.
The frequency scale adjusting method of speed measurement switch 5 is: after band conveyor 1 normal operation, adjust the potential device on speed measurement switch 5, (, under this frequency, show the belt normal operation, the lamp on speed measurement switch 5 does not glimmer) gets final product to make the output signal of potential device normal.
In the control of DCS system, according to the practical operation situation of on-the-spot speed measurement switch 5, stall signal has been carried out again to further processing:
1. according to the length of adhesive tape, is set a startup stall shielding time.
2. add a signal flash when adhesive tape normally moves and jump the shielding time delay.
3. stall signal only has protective effect when adhesive tape moves, and that is to say that adhesive tape is only when having run signal, just participation device protection.
4. the stall alert signal is jumped a condition of car protection as equipment, and this signal is delivered to the operation supervise and control picture simultaneously, for operator's reference, in order to notify in time the field staff confirm or process while stall alert occurring.
Above-mentioned functions can be used with being packaged into functional electronic block after trapezoidal pattern programming.
The utility model is under the condition in line with not increasing enterprise's extra investment; utilize existing hardware facility as far as possible; it is departure point that the software logic of DCS of take is controlled, and by configuration, the programming of DCS, the speed measurement switch of using in conjunction with Site Detection is realized protection automatically after travelling apron stall.Through the trial-production probationary certificate, can effectively avoid because of skid, expect multiple pressure extremely, the adhesive tape that causes of the reason such as rubber belt from deviating breaks, tears the generation of accident, thereby who knows the continuous reliability service of manufacturing line for the modernization large-scale cement, provides sound assurance.
