Description
Technical field
The present invention relates to a kind of belt break protection device for belt conveyor, especially a kind of Wedge-type full-section belt fender guard for upper conveying belt type conveyer that is applicable to the conveying of large conveying quantity coal.
Background technology
The Analysis of Technology of Broken Belt Protection for Uphill used the at present unloaded limits that adopt paired catching device to arrest belt more; although there is certain effect, exist the drawbacks such as the power of arresting is less than normal, belt is easily torn, the belt top structure stops convey materials, the catching device action is asynchronous.The mode of operation that separately has a small amount of belt conveyer to adopt full section to arrest: a kind of is that catching device directly is pressed on the belt that is paved with bulk cargo and realizes arresting, and another kind is first by belt jack-up, after time delay, belt is sandwiched in catching device and realizes arresting.These two kinds full section modes of arresting arrest that power is large, the stressed advantage such as more even of belt section, but they all need high-performance fluid power system, belt band speed detector and complicated control system, exist the high and poor problem of performance driving economy of requirement of explosion proof, and the former also exists the defect that the sharp-pointed spoil that sandwiches between belt and catching device and coal cinder damage belt.In addition, the material collision break catching apparatus of this two classes catching device in order to prevent from piling up, therefore the partial action module of catching device must cause the actuating length of catching device longer away from belt, is unfavorable for immediately arresting and increases the difficulty while arresting.
Summary of the invention
Technical matters: the objective of the invention is to overcome the deficiency in prior art, provide a kind of simple in structure, without power system, Wedge-type full-section belt fender guard for the upper conveying belt type conveyer that is swift in motion.
Technical scheme: Wedge-type full-section belt fender guard for upper conveying belt type conveyer of the present invention, comprise along upper fortune ramp direction and be placed in the frame on up belt, upper rack is provided with bend pulley, frame lower is provided with lower bend pulley, diff-H through the up belt downward bending of upper bend pulley and lower bend pulley changed course is 0.5m, on, the top of the up belt between lower bend pulley is provided with material slideway, material slideway is fixed on frame, frame is provided with flat-topped ridge, chute is housed on flat-topped ridge, be provided with voussoir in chute, the bottom of voussoir is provided with one-way rolling, the both sides up and down of frame are respectively equipped with and prevent only partially taking turns of belt deviation, described frame comprises upper beam, top longeron, batter post, lower beam, bottom longeron, vertical beam, flat-topped ridge, suspension column, wherein, upper beam is connected with the top longeron, lower beam is connected with the bottom longeron, the rear portion of upper beam and lower beam is provided with rear column, front portion is provided with batter post, between top longeron and bottom longeron, is provided with vertical beam, and the below of top longeron is provided with the flat-topped ridge fixing through diagonal brace, described voussoir comprises the wedge shape framework, and the wedge shape frame facet is embedded with the rubber block paralleled with belt, between rubber block and belt, leaves gap, and the both sides, inclined-plane of wedge shape framework are respectively equipped with wing plate, and the bottom surface of wedge shape framework is provided with rolling wheel support.
The top and the bottom of described material slideway are provided with respectively the belt cleaning brush; Leave the gap of 9-11mm between the lower surface of material slideway and the belt that lays out through lower bend pulley; Gap between described rubber block and belt is 9-11mm.
Beneficial effect: the present invention does not need high-performance engine installation when adopting full section to arrest, and the power of not only arresting is large, is difficult for tearing belt, has also saved complicated hydraulic power system, has reduced cost, has also avoided Explosion-Proof; Once the broken belt situation occur, because the break catching apparatus stroke is extremely short, can realize immediately arresting, reduce braking energy, protection equipment; Can guarantee that the be stuck position of braking of belt does not have bulk cargo, prevents sharp-pointed hard bulk cargo incised wound belt; The mode that voussoir adopts steel structure to surround rubber block, one side has guaranteed the relatively big difference of the friction coefficient of voussoir both sides, is convenient to the formation of wedge block self-locking state, has guaranteed on the other hand the intensity of voussoir; Do not need special broken belt detecting device.It is simple in structure, the speed of arresting is fast, safe, effective, has practicality widely.
