Description
One, technical field
The present invention relates to a kind of conveyer belt backward motion protector, especially a kind of conveyer belt backward motion protector that is applicable to mine.
Two, background technology
Its transportation angle of main fortune belt feeder of most mines is all between the 13-22 degree, so in a single day broken belt or belt feeder reversing accident take place in big angle, last belt can all become silted up to tail together with the material that band carries, and the fuselage cradle of belt feeder will be destroyed entirely, causes casualties and the mine stopping production; Therefore conveyer belt backward motion protector is a very important equipment; Under the existing situation, belt feeder upper strata belt glides generally has two kinds of reasons to cause: the one, and belt feeder is from the bottom up during transported material, when the transportation angle is big, if the unexpected broken belt of belt of operation, will cause the last belt of belt feeder to glide rapidly, cause the appearance of accident.The 2nd, when the belt band is loaded with lotus when big, the belt feeder brake failure, belt feeder reverses; More than two kinds of reasons, all can cause belt feeder upper strata belt to glide; The device that does not also have at present a kind of downslide of the last adhesive tape that prevents belt conveyer.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this invention is to provide a kind of conveyer belt backward motion protector, prevented the downslide of the last adhesive tape of belt conveyer.
For achieving the above object, the technical scheme that the present invention takes is: include electromagnetic spring pin I, electromagnetic spring pin II, baffle plate, damper brake, support, mercury binary pair, braking supporting plate and velometer; Velometer is arranged on the downside of belt conveyor, the cross-sectional plane of damper brake is set to fan-shaped and its bottom face is set to arc, by identical damper brake and the baffle plate of being disposed with the belt conveyor sense of motion, damper brake is set to the support articulated lifting arm and on this support, the downside of belt conveyor is provided with the braking supporting plate that is fixedly connected with support, the upper surface of braking supporting plate is set to contact with belt conveyor connection, the gauge head that is provided with the mercury binary pair that is fixedly connected with support and mercury binary pair at the downside of braking supporting plate is set to contact with belt conveyor connection, the bottom face of damper brake and the radius of center of turn are set to the distance greater than braking supporting plate and damper brake jointed shaft center, damper brake be set to another support on electromagnetic spring pin I articulate, another support is provided with and support pivotally attached baffle plate, and the electromagnetic spring pin II on baffle plate and the support articulates; The damper brake bottom face is provided with the anti-slip rubber face; The mouth of the input end of electromagnetic spring pin I and electromagnetic spring pin II, mercury binary pair and velometer is set to respectively connect with the controller of belt conveyer.
When the last adhesive tape of belt conveyor glides, the radar speedometer that is installed in fuselage sends the belt conveyor downslide signal of measuring to the controller of belt conveyer at once, the RT tachogen can be the controller that the signal of belt conveyor downslide sends belt conveyer to immediately with reverse direction operation, and the gauge head that belt conveyor touches the mercury binary pair makes the controller that produces the angle variation and the signal that belt conveyor glides is sent to belt conveyer; After the controller of belt conveyer receives belt conveyor downslide signal, cut off the motor power of belt conveyer at once, stop the belt conveyer running; Then by relay with electromagnetic spring pin II energising adhesive, spring pin is sucked into, baffle plate falls naturally, and the material that glides is all stopped; 0.3 after second, with electromagnetic spring pin I energising adhesive, after spring pin was sucked into, damper brake dropped to vertical position naturally by relay; At this moment, without any material, the anti-slip rubber face and the last tape surface of damper brake contact on the following belt conveyor that slides into herein; Damper brake and the gap of braking between the supporting plate are more and more littler, the most at last belt conveyor tightly squeeze damper brake with brake between the supporting plate; Owing to designed damper brake, because damper brake and braking supporting plate surface all are surrounded by rubber layer, all have bigger friction force simultaneously, therefore prevented the downslide of the last adhesive tape of belt conveyer.
The present invention has designed, and is provided with gear structure in an opposite direction at the side of the pivotally attached axle of baffle plate and support, damper brake and support.Anti-baffle plate and damper brake backward rotation.
The present invention has designed, and velometer is set to RT tachogen or radar speedometer or RT tachogen and radar speedometer.Guaranteed that outgoing signal is accurate.
The present invention has designed, and the RT tachogen is set to the two-way range rate measurement device.
The present invention has designed, and the bottom face of an end of damper brake and the radius R 1 of center of turn are set to greater than the bottom face of its other end and the radius R 2 of center of turn.Can rotate with the drive that last adhesive tape glides.
The present invention has designed, and the upper surface of braking supporting plate is coated with rubber.Reduced infringement to belt conveyor.
The present invention has designed, and also includes locating plate; Support is provided with and the support locating plate that is fixedly connected, and locating plate is set to contact with baffle plate connection when baffle plate is vertical.The shunting material is quick.
