Description
Technical field
This protection technique field is indulged the present invention relates to the belt of conveyer, in particular to a kind of photo resistance belt indulges this guarantor
Protection unit.
Background technique
Currently, the speed of service of rubber conveyer is very fast, once adhesive tape, which occurs, tears accident, rubber conveyer driver is only depended on
And it is inadequate for patrolling personnel's discovery processing, first is that the working environment of underground rubber conveyer is poor, as coal dust is big, dark, glue
Band has coal etc. above, these factors affect the judgement and reaction of people, not only occurs over just the on duty of driver second is that tearing sometimes
Position, prevent operator on duty from finding and making emergency processing in time, therefore, only makes an inspection tour to come by rubber conveyer staff
The scuffing or tearing for avoiding adhesive tape, are unpractical.Once and accident occur, such as handle not in time, will result in it is serious after
Fruit.
Longitudinal tear phenomenon will not occur in normal operation for the adhesive tape of rubber conveyer, only when the serious sideslip of adhesive tape or
External pointed object such as steel plate, iron block, I-steel, anchor pole, bulk spoil etc. when protruding into adhesive tape is possible to that adhesive tape is caused to scratch,
Adhesive tape is caused to tear when serious.Rubber belt from deviating causes the general only tearing adhesive tape side of adhesive tape tearing, does not appear on the inside of adhesive tape.It wants
Rubber belt from deviating is prevented to be easier, it is only necessary to install, and normal use as required during installation, generally be not in serious glue
Band tearing accident.But adhesive tape scuffing or longitudinal tear accident are caused more frequent occurrence since pointed object protrudes into adhesive tape.
Presently, there are adhesive tape protective device include three types: (1) ZS1-G induction type longitudinal fracture detector: the dress
Can set need to use special adhesive tape, and investment is larger, be considered as on existing adhesive tape coil being arranged by other approach；(2) intrinsic safety
The anti-tear sensor of type: this device was installed on rubber conveyer, but be there is no and worked, only to the serious glue of tearing
There is certain protective effect with conveyer accident, the accident or adhesive tape for generation in other places are only scratched or accident initial stage
Although adhesive tape is torn, can't detect but without the case where coal breakage；(3) SL longitudinal tear switchs: it only tears adhesive tape
And the accident suspended in midair works, but when longitudinal rupture of adhesive tape, few adhesive tapes suspend in midair, tear the object of adhesive tape also not
It centainly suspends in midair, and even more of no avail for the scuffing of adhesive tape.
Therefore, it is badly in need of wanting a kind of protective device for detecting adhesive tape interruption of service by light.
