Abstract
Description
Technical field
The utility model relates to a kind of feeding crushing machine coal piling protective device and feeding crushing machine.
Background technology
In the prior art, adopt velocity sensor to realize the locking shutdown between the belt of feeding crushing machine and feeding crushing machine.But, therefore the fault of for example akinesia often occurs, thereby cause production accident because the fault rate of velocity sensor is higher.Therefore, be necessary to design a kind of novel material disintegrating machine coal piling protective device, to overcome above-mentioned defective.

Description of drawings
Fig. 1 is the structural representation of the disintegrating machine coal piling protective device of a kind of specific embodiment of the utility model.
The specific embodiment
Feeding crushing machine coal piling protective device in a kind of specific embodiment of the utility model comprises: misalignment sensor 101, protector 102; described misalignment sensor 101 is connected with protector 102, and described protector 102 has and is used for the normally closed contact 103 that is connected with the control end of feeding crushing machine controller.
Described misalignment sensor 101 is connected with protector 102 by connecting line 104.Described connecting line 104 can be any suitable power line or holding wire.Selectively, in other preferred implementations, the sensing signal of described misalignment sensor 101 also can be sent to protector 102 by wireless propagation path.
Described protector 102 can be realized by switch elements such as relay, breakers.Normally closed contact 103 on the protector 102 is connected with the control end of material disintegrating machine controller, is used to control the startup of described controller and stop.When running well, described normally closed contact 103 closures, when breaking down, described normally closed contact 103 disconnects, thereby the control loop of feeding crushing machine controller is cut off.
Described misalignment sensor can be the misalignment sensor of any suitable model.Be preferably GEJ25/35 type misalignment sensor, this misalignment sensor has beaming roller, and under normal condition (during no sideslip), described beaming roller is vertical with the belt edge line, keeps certain distance between the two; When belt because of unbalance loading sideslip took place, belt and beaming roller mutual friction mutually, and force beaming roller to be offset when beaming roller pendulum angle during greater than predetermined angular, microswitch action, sent early warning signal or cut off the control loop of material disintegrating machine controller; After fault was got rid of, the beaming roller of misalignment sensor returned to normal condition again.
Correspondingly, the utility model also provides a kind of feeding crushing machine.Described feeding crushing machine comprises unloading point retaining coal skin, feeding crushing machine coal piling protective device and feeding crushing machine controller.Described feeding crushing machine coal piling protective device comprises misalignment sensor, protector.Described misalignment sensor is by being connected with protector, and described protector has the normally closed contact that is connected with the control end of feeding crushing machine controller.The structure of described feeding crushing machine coal piling protective device as mentioned above.
Misalignment sensor is installed in the side of unloading point retaining coal skin.Preferably, in the both sides of unloading point retaining coal skin misalignment sensor has been installed all.
The both sides of unloading point retaining coal skin are provided with stator 105, and misalignment sensor is installed on the described stator 105.Described stator 105 can be formed by iron sheet, and for example: each stator can be formed by the iron sheet of 450mm * 400mm.
In the course of work of feeding crushing machine, the belt running, the material (for example coal) that drives on the belt advances.A misalignment sensor is respectively installed in unloading point retaining coal skin both sides at the feeding crushing machine.After belt stopped, disintegrating machine unloading coal touched the misalignment sensor that retaining coal skin is pressed from both sides, and makes misalignment sensor move, and the normally closed point of introducing electric-control system disconnects, and makes the disintegrating machine pump controller out of service automatically.
Although it will be understood by those skilled in the art that the utility model is to be described by above-mentioned preferred embodiment, its way of realization is not limited to above-mentioned embodiment.Should be realized that under the situation that does not break away from the utility model purport those skilled in the art can make different variations and modification to the utility model.
