Compared with the prior art, the stockpile protective device of the belt conveyer has the advantages of being reasonable in design, simple in structure, convenient to use, notable in effect and the like, labor intensity of workers is relieved, and meanwhile the effect of automatic and human-based management of a coal cleaning plant is enhanced.
Description
Technical field
The utility model relates to a kind of coal mine machinery, specifically a kind of belt transporter windrow fender guard.
Background technology
It is to utilize enough raw coal amounts to promote from the side the mode of operation that the limit switch action just can stop belt feeder that head coal piling protecting device, its principle are arranged during the design and installation of raw coal belt transporter.Its shortcoming is slow in reacting, and the scene also can not be piled up so much raw coal and just be responded, so the almost not effect of original coal piling protecting device.Often obstruction causes industrial accident but the washery raw coal enters to wash belt conveyer head for various reasons.
Because raw coal quality unstable (lump coal granularity large, high, the former moisture content of coal of duff content is large, transportation volume is excessive, coal supply is inhomogeneous etc.) can cause swirler to enter charging basket silt coal, the post worker is if in time find, silt coal amount may be lacked.If can not in time find, probably cause very serious consequence.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, and a kind of reasonable in design, the significant belt transporter windrow of effect fender guard is provided.
The technical scheme that its technical matters that solves the utility model adopts is:
Belt transporter windrow fender guard comprises erecting frame and approach switch, and approach switch is arranged on the erecting frame, is provided with protection switch and corresponding with approach switch on the erecting frame of described approach switch one side.
Belt transporter windrow fender guard, its described protection switch comprises bracing frame and revolving bar, and the revolving bar middle and upper part that vertically arranges links together by center shaft and bracing frame, and revolving bar can center shaft be that rotate with respect to bracing frame in the center of circle; Revolving bar upper end is corresponding with described approach switch, and the lower end is provided with the buildup baffle plate and is connected with the one end, the buildup baffle plate other end to the revolving bar opposite side namely with respect to the lopsidedness of approach switch and and revolving bar between form the angles of spending less than 90.
Belt transporter windrow fender guard, it also comprises control box, is provided with time relay on the control box, aforementioned approach switch is connected with control box.
Belt transporter windrow fender guard of the present utility model compared with prior art, the beneficial effect that produces is:
The utlity model has the characteristics such as reasonable in design, simple in structure, easy to use, function admirable, practicality, solved the post worker and no longer stared at into charging basket to high-pressure.Owing in manufacturing process, requiring native system sensitivity very, and can regulate about the coal piling pointer, guaranteeing that silt coal position is not higher than into charging basket, so there has not been the health amount, has alleviated post worker's labour intensity.The second washery automation, human-based management effect have also been strengthened simultaneously.

Among the figure: 1, erecting frame, 2, approach switch, 3, bracing frame, 4, revolving bar, 5, center shaft, 6, the buildup baffle plate, 7, control box, 8, time relay.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail below.
As shown in drawings; belt transporter windrow fender guard of the present utility model; its structure comprises erecting frame 1 and approach switch 2, and approach switch 2 is arranged on the erecting frame 1, is provided with protection switch and corresponding with approach switch 2 on the erecting frame 1 of described approach switch 2 one sides.Described protection switch comprises bracing frame 3 and revolving bar 4, and revolving bar 4 middle and upper parts that vertically arrange link together by center shaft 5 and bracing frame 3, and revolving bar 4 can center shaft 5 be that rotate with respect to bracing frame 3 in the center of circle; Revolving bar 4 upper ends are corresponding with described approach switch 2, and the lower end is provided with buildup baffle plate 6 and is connected with the one end, buildup baffle plate 6 other ends to revolving bar 4 opposite sides namely with respect to the lopsidedness of approach switch 2 and and revolving bar 4 between form the angles of 45 degree.Aforementioned approach switch 2 is connected with control box 7, is provided with time relay 8 on the control box 7, and control box 7 is connected with power supply with central control system again.
The principle of belt feeder windrow fender guard is to have utilized dexterously the principle of throw of lever according to the bulk of production scene; the long-armed material level when surveying coal piling of revolving bar, revolving bar galianconism be by center shaft the signal feedback during long-armed the action to the short time delay relay.After the normal startup of wash coaling equipment, native system is in wait state always, does not affect the normal operation of washery centralized control system.After material level that swirler enters charging basket acquires a certain degree, because the thrust that buildup glides is touched the buildup baffle plate, then revolving bar is with the center shaft left-hand revolution, also rotate when touching approach switch thereupon the upper end, and (0～10S) gets electric work to the short time delay relay.If in the short time delay scope, buildup baffle plate return, the zero clearing of short time delay relay illustrates that not being real stops up the coal piling that causes owing to entering to wash raw coal, but feinting deception.The effect of short time delay relay be exactly eliminate feinting deception (feinting deception mainly be moment buildup and belt feeder on the inhomogeneous institute of material cause), determine whether coal piling.After if the short time delay relay surpasses the value that sets, the intermediate relay self-saturation wherein has a secondary normally closed contact to disconnect the coal piling signal switch of belt feeder head.Because the interlocking effect of centralized control system stops feeder and belt feeder, the Warning light that is located on the post lights, and shows simultaneously on the computer screen of central control system and stops up the silt coal.The short time delay relay electric-loss, counting machine is from adding 1.After waiting for buildup baffle plate return, (0～99S) gets electric work to the long time delay relay, after the time-delay of wait relay is complete, automatically triggers native system and resets.Again be in wait state.
This device is stronger to various production scenes adaptive capacity.Just can adapt to various production scenes as long as adjust the time of slug relay, the length of buildup baffle plate etc. according to the scene.Behind the buildup baffle plate return, be to determine the coal piling alarm with the time-delay of time relay, the length that the time is adjusted can be according to in-situ determination.This device is processed according to lever principle, the nature lowering is in the scene, and water proof and dust proof is anti-riot, and fulcrum rotates not to be afraid of flexibly to vibrate is not afraid of wearing and tearing, actuating signal adopts non-contacting time relay transmission and control, can say under various complex environments well workpiece.Calculate the time of eliminating from the silt coal to the silt coal, system can also recover normal operation automatically.
Its processing and fabricating of belt transporter windrow fender guard of the present utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except the described technical characterictic of specification sheets, be those skilled in the art's known technology.
