Description
Technical field
The utility model relates to checking system, specifically a kind of checking system for detecting coal seam thickness on belt feeder.
Background technology
Current coal mining, processing industry use belt feeder as Coal Transport mode in a large number, and coal can be transported to earth's surface from exploitation by belt feeder.Present belt feeder does not detect coal seam thickness, does not also have corresponding safety prevention measure, needs regulate manually or close belt feeder when being occurred by unforeseen circumstances.
In view of the popularity that currently marketed belt feeder uses, and cause the uneven of belt feeder coal seam thickness because preceding working procedure coal output is unstable, easily cause the safety misadventures such as slipping of the belt, fracture, blocking.But so far not for the detection alarm equipment of belt feeder, the research and development of this kind equipment are very urgent.
Current belt machine fortune coal Problems existing:
1. do not have coal seam thickness safety prevention measure, the coal cinder on belt easily drops;
2. there is no overload protection measures, easily cause the safety misadventures such as coal cinder landing, belt longitudinal tear and blocking when delivering coal cinder weight and exceeding belt feeder maximum load.
3. need to regulate manually, when overload appears in belt feeder, coal cinder drop or the unforeseen circumstances such as belt fracture time, need to regulate manually or disable motor, the reaction time is long, has potential safety hazard.
Utility model content
The purpose of this utility model is for overcoming the deficiencies in the prior art, and design a kind of checking system for detecting belt feeder coal seam thickness, the transportation volume that this system can realize coal under the premise that security is guaranteed maximizes, stability and the homogeneity of Coal Transport is realized, to reach the object of safety in production and saving labour power by controlling motor speed.
The technical scheme realizing the utility model object is:
A kind of checking system for detecting belt feeder coal seam thickness, comprise control module and the execution module, signal processing module and the monitoring modular that are connected with control module respectively, monitoring modular is made up of the coal seam thickness monitoring sensor be arranged on above belt feeder and the motor speed detecting sensor be connected on motor shaft, coal seam thickness monitoring sensor is connected with signal processing module respectively with motor speed detecting sensor, the signal measured is input to signal processing unit analysis, and control module is also connected with alarm modules.
Described coal seam thickness monitoring sensor comprises baffle plate, be arranged on the rotating shaft between baffle plate and be arranged on multiple contacts of shaft end.
Described motor speed detecting sensor is also arranged on the drum shaft of belt feeder end.
The beneficial effects of the utility model are: structure is simple, easy to operate, coal seam thickness detecting sensor is utilized to carry out on-line real-time measuremen to coal amount on belt feeder, and by Signal transmissions to signal processing unit and control unit, control unit regulates motor speed, thus the weight of coal on change belt feeder, to reach the object of maximize utility under the prerequisite of safety in production, solve when breaking down simultaneously and need problems such as shutting down manually; System accurately can detect whether cause the accidents such as slipping of the belt, fracture, blocking because transport coal seam is too thick.And automatically identified by coal seam thickness and adopt different motor speed, without the need to artificial selection.Simple to operation, switch motor speed is fast, and greatly improves the safety of production scene, and productive costs is low, is suitable for promoting.
1. achieve stability and the homogeneity of belt feeder transmission coal, enhance productivity.
2. achieve automatic control, make workman away from bad working environments, improve circumstance and ensure safety of employees simultaneously.
3. achieve the automatic monitor and forecast that coal transports on belt feeder, save labour power, improve automatization level.
4. the utility model also can be used for other bulks, the transport of powdered substance belt feeder controls occasion.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Figure 1, a kind of checking system for detecting coal seam thickness on belt feeder of the utility model, is made up of control module and the signal processing module, monitoring modular and the execution module that are connected with control module.Control module is also connected with alarm module, wherein: (as shown in Figure 2) monitoring modular is made up of the coal seam thickness monitoring sensor 4 be arranged on above belt feeder 3 and the motor speed detecting sensor 2 be connected on motor shaft 1, and the signal measured is input to signal processing module analysis by coal seam thickness monitoring sensor 4 and motor speed detecting sensor 2.Motor speed detecting sensor 2 is also connected on the drum shaft 5 of belt feeder end.
As shown in Figure 3, described coal seam thickness monitoring sensor 4 is made up of baffle plate 4-3, multiple contact 4-1 of being arranged on the rotating shaft 4-2 between baffle plate 4-3 and being arranged on rotating shaft 4-2 end.
As shown in Figure 4, the signal after process is input to control unit by signal processing unit, and motor 1 is adjusted to different rotating speeds by for different coal seam thicknesses by control unit.When the data that coal seam thickness monitoring sensor 4 reads are for " low ", control unit will make motor 1 underdrive, conserve energy.When the data that coal seam thickness monitoring sensor 4 reads are in " height " for a long time, motor accelerates rotation makes coal seam thickness decline, simultaneously-signal processing unit is by the rotation speed monitoring sensing data at the rotation speed monitoring sensor 2 at comparison motor 1 place and cylinder 5 place, show that when both data difference are greater than a certain numerical value slipping of the belt is serious, system is by stopping alarm; If the data that coal seam thickness monitoring sensor 4 reads are in " height " for a long time but do not occur skidding, belt feeder rotating speed will keep at a high speed, strengthening transportation volume.If motor is can not speed governing, when coal seam thickness is in high, then system sends alarm to prime, and prompting reduces coal mining output and ensures safety.System will detect the position of coal seam thickness sensor in real time, takes different motor speed at diverse location, and gives the alarm when danger occurs.
The utility model is described by embodiment, but the utility model is not construed as limiting, with reference to description of the present utility model, other changes of the disclosed embodiments, as the professional person for this area easily expects, such change should belong within the scope of the utility model claim restriction.
