Description
Technical field
The utility model relates to a kind of chute blocking and detects fender guard, can widespread use coal chemical technology belt conveyor in, belong to chute fault detection panalarm technical field.
Background technology
In coal chemical technology, travelling apron is used for transport and the reprinting of material.Chute is as its auxiliary facility, often blockage phenomenon.If process not in time, can cause the stuck or electrical fault of travelling apron.The weighing lever chute blocking detection alarm device in chute outside at present; its weighing process is carried out in chute outside; the measure of covering is not set between meausring apparatus and chute outgate; being vulnerable to running orbit in normal feed, through the impact of the material impact of outgate, produces maloperation and causes shutdown.After alarm release, in meausring apparatus, use the subsequent treatment of overflowing material to rely on labor cleaning to complete more, length consuming time, efficiency is lower.Liftoff when higher when the high site of chute blocking, it is more inconvenient to weigh the weighing process of lever warning device and overflow labor cleaning's operation of material.
Therefore, produce maloperation signal for preventing that chute blocking from detecting, realize the technical matters that is automatically treated as urgent need solution of overflowing material.
Summary of the invention
The utility model is intended to address the above problem, and provides a kind of safety of operation stable, and can detect in time and provide stoppage protection by block information, and can be after failure alarm signal is removed, the chute blocking of automatically processing overflow material detects and fender guard.
This realizes above-mentioned purpose, and the technical scheme that the utility model is taked is: be communicated with a secondary chute at the high-order sidewall of chute.Secondary chute is provided with antifriction rubber sheet, inclination plank, retracing spring, spacing iron block, movable iron plate and rotating shaft, feeler lever, touch switch, combined aural and visual alarm, wire, movable iron plate, grid section.Wherein grid section, antifriction rubber sheet are connected with chute inwall bolt, and grid section mesh can pass through 80% supplied materials, and antifriction rubber sheet is naturally along hanging down.The angle of inclination plank is a bit larger tham material angle of repose, can move by easy on and off.Retracing spring top, bottom are fixed with inclination plank, secondary chute respectively, and feeler lever is fixed on inclination plank bottom, and top is provided with contact.Rotating shaft and the welding of chute outer wall, movable iron plate can rotate to chute inwall around the shaft.Touch switch is arranged under feeler lever, is connected with combined aural and visual alarm wire, and chain with the electric machine control system of chute charging gear.
Compared with existing technology, the beneficial effects of the utility model are as follows.
1, the utility model testing result is accurate, and the grid section of setting, antifriction rubber sheet have prevented that bulk materials and a large amount of dust stratification from entering the maloperation that secondary chute causes.
2, detecting after obstruction, can send photosignal, playing alarm function, stopping upstream feeding device simultaneously, ensureing that chocking-up degree no longer increases the weight of.
3, after alerting signal is removed, can automatically remove the material of overflow.It is simple in structure, easy to make, and operability is high.
Brief description of the drawings
The structural representation that accompanying drawing 1 is utility model.
Accompanying drawing 2 is the schematic diagram that after chute block clearing, utility model is removed overflow material.
Above-mentioned number in the figure is described as follows:
1, secondary chute; 2, antifriction rubber sheet; 3, inclination plank; 4, retracing spring;
5, spacing iron block; 6, feeler lever; 7, touch switch; 8, combined aural and visual alarm;
9, wire; 10, rotating shaft; 11, movable iron plate; 12, grid section
Detailed description of the invention
Referring to accompanying drawing 1.A kind of chute blocking detects fender guard, comprises secondary chute (1), antifriction rubber sheet (2), inclination plank (3), retracing spring (4), spacing iron block (5), feeler lever (6), touch switch (7), combined aural and visual alarm (8), wire (9), rotating shaft (10), movable iron plate (11), grid section (12).Wherein, grid section (12) is fixed on chute inwall with antifriction rubber sheet (2) upper end, and grid section mesh can pass through 80% supplied materials, and antifriction rubber sheet (2) is naturally along hanging down.The angle of inclination plank (3) is a bit larger tham material angle of repose, can move by easy on and off.Retracing spring (4) top, bottom are fixed with inclination plank (3), secondary chute (1) respectively, and feeler lever (6) is fixed on inclination plank (3) bottom, and top is provided with contact.Rotating shaft (10) is welded on chute outer wall, and movable iron plate (11) around the shaft (10) rotates freely.Touch switch (7) is arranged under feeler lever (6).
When chute is normally worked, grid section (12), antifriction rubber sheet (2), movable iron plate (11) form barrier, stop bulk materials, a large amount of dust stratifications to enter secondary chute (1), avoid the maloperation causing.
Chute blocking, when material level rises on movable iron plate (11), movable iron plate forms an outgate between chute and secondary chute.Obstruction material is pushed antifriction rubber sheet (2) open and is entered secondary chute (1), drops down onto inclination plank (3) upper, compression reseting spring (4), feeler lever (6) declines, touch switch is touched in contact, and touch switch is connected with combined aural and visual alarm, and chain with the electric machine control system of chute charging gear.Combined aural and visual alarm is reported to the police, and charging gear motor shuts down simultaneously.
Spacing iron block (5) has limited the falling head of inclination plank, prevents that contact is after contacting with touch switch, and feeler lever continues to decline, and plays the effect of protection Compress Spring simultaneously.
After alarm release, material level declines gradually, sees accompanying drawing 2.Be down to movable iron plate (11) when bottom at material level, under the upper stacking material of inclination plank (3) promotes, (10), towards inwall rotation, stacking material is discharged in chute movable iron plate (11) automatically, spring reset around the shaft.
