Description
Technical field
The present invention relates to belt conveyor fender guard, particularly relate to belt conveyor and tear automatic stop jumping device.
Background technology
Belt conveyer is mainly used to carry the materials such as block, granular and powdery, also can carry the goods of member simultaneously.Belt conveyer, because it has the advantages such as operational throughput is large, structure is simple, easy to maintenance, cost is low, highly versatile, is widely used in the industries such as metallurgy, coal, mine, building materials, electric power, light industry, grain, harbour, boats and ships.Belt is in transportation. and longitudinal tear is the damage type that a kind of destructiveness is very large, once tear accident, shuts down not in time, the whole piece belt being worth unit even up to a million of hundreds of thousands of unit will soon be damaged, cause huge economic loss to enterprise.The enterprise that this type of phenomenon almost uses adhesive tape to transport loose shape mineral all can occur, and has become that enterprise is worried most, one of most last headache.Therefore, research prevention belt conveyor large area tears the key subjects becoming business equipment safe operation.
Band conveyor is in transportation, and belt tearing is based on longitudinal tear, and harm is large, therefore does following analysis with regard to belt longitudinal tear reason:
1, belt deviation is torn.In belt operational process, when the one-sided skew of belt is more, forms fold in side and to pile up or folding, be subject to unbalanced pulling force or crushed, scratch etc. cause belt tearing;
2, loose core and tear (only betiding steel rope core belt).Material transfer, belt is under violent impact force action, cause the wire cable rupture in belt sometimes, through External Force Actings such as grinding for a long time, press, roll over, draw, the steel wire rope head of fracture can expose outside lid glue from belt connector, sticky mouth place or the more serious place of wearing and tearing.When the steel rope exposed reaches certain length, just may twist into the place such as cylinder, carrying roller, along with the running of belt, steel rope is extracted out from belt lid glue, cause tear wound or belt cleaner scrape metal filament or other foreign material that plate holder tangles belt surface, belt tearing;
3, material or the blocking of foreign material card pressure are torn.This situation occurs in hopper and deflector chute joint portion.Because the distance between the front lower edge of hopper and strap surface is limited, and under belt, impact idler is spaced apart, and natural bearing capacity intensity is uneven.When transported material or impurity length exceed this distance, easily make bulk materials be stuck between hopper forward position and belt in a special case, powerful extruding belt causes that belt is rigid to be torn;
4, foreign matter scratches.This damage often occurs in hopper bottom, belongs to belt type of injury the most general.There are three kinds of situations: one is that elongated rod shape sharp weapon pressure scratches.When the longitudinal size entering hopper end opening foreign matter is greater than its carrying capacity, foreign matter will be stuck in chute bottom.By the supercharging that travels forward of belt, thus scratch belt.Two is that sharp weapon penetrance scratches.According to requirements of process, the tandem array place of two belts will reach certain space drop, like this with regard to having put aside certain potential energy to the material of upper belt, naturally produces certain speed when falling lower belt.If be mixed into sharp-pointed sharp weapon unexpected in material, when contacting belt due to effect of inertia, sharp weapon directly penetrate leather belt buckle on carrying roller, and top is blocked by chute forward position, form sharp sword, cause and tear in the proal process of belt.Three is that other scratch, and as damaged in roller supporting tube skin, end cap snaps.
Summary of the invention
For above-mentioned existing problems; the object of this invention is to provide a kind of structure simple, install easily, can when belt conveyor is torn the device of automatic stop jumping, make the belt torn out of service in time, the timely Concatenate shut-down of last process belt conveyor; stop feeding, stop putty.
The present invention realizes above-mentioned purpose by the following technical solutions: belt conveyor tears automatic stop jumping device, guide wheel is provided with above frame, above guide wheel, belt conveyor is housed, belt conveyor below for returning, it is characterized in that, the both sides of frame are fixed with limit switch, and limit switch is positioned at the below of the belt conveyor returned, and the push rod of limit switch is connected with cross bar.
Advantage of the present invention is: structure is simple, it is easy, safe and practical to install.Tearing appears in belt conveyor, tear fracture time, the belt that breaking part is torn touches cross bar, pulls the push rod on limit switch, impels limit switch to disconnect, timely stop jumping, avoids belt conveyor large area to tear and the damage of belt frame.Take this measure belt to damage few, equipment recovers fast, without any factor jeopardizing safety of employees, significantly decreases employee's work work capacity and labour intensity simultaneously.When fracture occurs belt, belt is out of service, and the timely Concatenate shut-down of protection belt last process belt, stops feeding, stop putty.Greatly can protect belt, extend the service life of belt, reduce the equipment cost of enterprise.
