Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical scheme of the present invention is described in detail.
Belt transporter material monitoring device of the present invention comprises at least two charge level detectors, and Fig. 1 shows the structured flowchart of charge level detector 100, and it comprises: support 101, removable feeler lever 102, multiple proximity switch 103 and signal processing module 104; Wherein, removable feeler lever 102 and multiple proximity switch 103 are installed on support 101, all proximity switches 103 are electrically connected with signal processing module 104, the position of each proximity switch is spaced to form multiple gear, when removable feeler lever 102 moves to the some gears in multiple gear, corresponding proximity switch can be triggered.Signal processing module 104 receives the signal that proximity switch is triggered, and is uploaded to upper computer afterwards and processes.
Belt transporter material monitoring device of the present invention and belt transporter, material feeder coordinating operation.Position near a material outlet charge level detector 100 being placed on feeder, is placed on belt transporter and will starts position near climbing by another charge level detector 100.During work, removable feeler lever 102 is utilized to detect the material transportation amount on the belt feeder of these two positions, when material transportation amount is in normal range, removable feeler lever 102 mobile range on two charge level detectors 100 little (or not moving), the proximity switch gear of triggering is not high (or not triggering proximity switch); When material transportation amount is larger, material occurs to pile up, the mobile range of removable feeler lever 102 increases, and the proximity switch gear of triggering is high.The gear of proximity switch is triggered by the removable feeler lever 102 comparing two charge level detectors 100, judge whether to occur extremely, adjust the feeding coal (increase, reduce or stop feed) of feeder if any abnormal reporting system immediately or operating personal, guarantee that belt feeder works well.
Fig. 2 and Fig. 4 respectively illustrates the working state figure of the charge level detector 100 in different embodiments of the invention, and place charge level detector 100 according to diagramatic way, object is the top making detector major part be positioned at belt transporter 200.
In Fig. 2 embodiment, the support 101 of charge level detector 100 is provided with fork, and fork can rotate around rack beam, at the end of fork, touch panel being installed, the area of contact with material can being increased, when belt transporter there being material transferring, touch panel contacts with material, and fork rotates thereupon and turns over.Composition graphs 3, multiple proximity switches 103 are positioned at the plane of rotation of fork, and when fork swings and turns over, corresponding proximity switch is triggered, and show that belt transporter 200 has and carry; If increase feeding coal, the piling height of material increases, then fork on turn over angle and increase, when reaching default full load conditions, corresponding proximity switch is triggered.In like manner, the difference of multiple proximity switch to material can be arranged transport situation and detect.
In Fig. 4 embodiment, support 101 is provided with stop collar 102 '-1, the straight-bar 102 '-2 of a rigidity is vertically placed through stop collar 102 '-1, and stop collar 102 '-1 is the tubular structure of hollow.In other embodiments, stop collar also can be designed to annulus, square frame or other there is the structure of space position-limiting action, guarantee that straight-bar 102 '-2 only can move by the vertical direction.Composition graphs 5, the proximity switch of differing heights, near multiple proximity switch 103, can be triggered in the upper end of straight-bar 102 '-2 when straight-bar 102 '-2 moves up and down.The lower end of straight-bar 102 '-2 is connected with another straight-bar 102 '-3, point of connection is in the bar portion (non-end) of straight-bar 102 '-3, and both by one rotating shaft 102 '-5 connect, make straight-bar 102 '-3 can in the paper plane shown in Fig. 5 around the shaft 102 '-5 rotate.In addition, for two ends of straight-bar 102 '-3, one end thereof is fixed end (such as can be fixed on support 101), the other end is free end, then change the height of this free end, can lifting straight-bar 102 '-2 (moving up), or sedimentation straight-bar 102 '-2 (moving down).
In Fig. 5 embodiment, the free end of straight-bar 102 '-3 is provided with roller 102 '-6, can increase detector 100 and the area of contact of material, also can reduce contact friction, make testing process more smooth and easy.
In Fig. 6 embodiment, the fixed end of straight-bar 102 '-3 is connected with straight-bar 102 '-4, and both are connected by a rotating shaft 102 '-5, and straight-bar 102 '-4 other end is fixed on stop collar.This removable feeler lever compact conformation on the whole, is convenient to safeguard.
In Fig. 4 embodiment, every platform charge level detector there are three proximity switches, distinguish corresponding " have and carry ", " being fully loaded with " and " overload " gear from low to high, the height of each gear can be set according to conditions such as the kind of material (such as coal charge, cement, grain etc.) and belt transporter efficiencies.During work, the charge level detector A being positioned at position near feeder material outlet can detect current feeding coal, and detector A should be kept only to trigger the proximity switch of " have and carry " gear; Meanwhile, be positioned at belt feeder will start the to climb charge level detector B of position can detect and currently whether to exist because the overloading caused is piled up in the gravity flow of upward slope material.Specifically, if detector A and detector B is current be all in " have and carry " gear, illustrate that material transportation is steady; If detector A is in " have and carry ", detector B is in " being fully loaded with ", illustrates that material gravity flow has appearred in the climbing position at detector B place, define certain accumulation, but material transportation still can maintain, at this moment can send alarm, reduce feeder feeding coal, avoid gravity flow to increase the weight of; If detector A is in " have and carry ", detector B is in " overload ", and illustrate that the material gravity flow of detector B position is serious, should close feeder immediately, stop feed, Accident prevention occurs.
In other embodiments of the invention, charge level detector can be placed on other position of belt feeder, such as easily there is the position of spreading or belt deviation, by arranging suitable proximity switch, when this position height of materials being detected lower than discharging opening height of materials, can be judged as there occurs spreading phenomenon.
Above, be described in detail in conjunction with specific embodiments to technical scheme of the present invention, described specific embodiment understands thought of the present invention for helping.The derivation that those skilled in the art make on the basis of the specific embodiment of the invention and modification also belong within scope.
