Abstract
The utility model provides a conveying belt tearing alarm and protection device, which comprises an electric appliance control box which is connected with an electric appliance switch used for controlling the stop of a conveying belt; the electric appliance control box is also connected with at least one group of sensors and the sensors are symmetrically arranged below both sides of the conveying belt. The conveying belt tearing alarm and protection device is specially designed as alarming equipment for the abnormal conditions of belt slip material scattering and conveying belt tear. The belt slip material scattering and the conveying belt tear can be rapidly and reliably detected and when the abnormal conditions occur, a computer can directly send alarming signals to a main control room, thereby fundamentally preventing the conveying belt from occurring the possibility of the large area tearing problem. The device has the advantages of simple structure and great practicability.
Description
Technical field
The utility model relates to a kind of conveyer band discerption reports to the police and fender guard, refers to that especially a kind of load-transfer device that is used in the warning of course of conveying longitudinal tear and stop automatically, prevents that the conveyer band discerption of the longitudinal tear extension of load-transfer device from reporting to the police and fender guard.
Background technology
The preventive device of domestic current use at present mainly is two kinds: first kind of its detector is installed in conveyer hopper below, for blocking cable-styled device, when belt tearing leaks down the bulky grain material, cuts off the electric current that blocks rope by its weight, thereby produces alerting signal.
Second kind is mounted under the load-transfer device, and after load-transfer device was pierced, foreign matter cut off the electric current of detector, produced alerting signal.
But above two kinds of equipment all exist serious technological deficiency, and there is wretched insufficiency in the principle of its detection:
1, belt is in course of conveying, because load-transfer device is tight, when the situation of tearing, it leaks material and mostly is granule, and its mass deficiency is to cut off the electric current of first kind of detector, and it is many after the belt occurrence of large-area is torn therefore to report to the police, at this moment, belt is scrapped basically.
2, belt tearing is not only that the damage of piercing through property produces, and is the belt tearing that causes owing to the damage that stabbing takes place under many circumstances.When not piercing through, the belt tearing panalarm also can't the generation effect in second.
3, the position of belt tearing generation generally is to be created in about five meters in hopper the place ahead, rather than occurs in the hopper below, and therefore all there is critical defect in above-mentioned first kind detection principle and technology.
Summary of the invention
The utility model provides a kind of conveyer band discerption to report to the police and fender guard, at above-mentioned existing in prior technology defective, and the panalarm that main purpose has been to provide a cover to occur at abnormal condition such as belt deviation spreading and conveyer band discerptions specially.At first but at high speed, reliable detection go out belt deviation spreading and conveyer band discerption, and when abnormal condition occurring, computer directly sends alerting signal to main control room, fundamentally stop the conveyer belt occurrence of large-area and tear the possibility that situation occurs.
For realizing above-mentioned purpose, the utility model is taked following technical scheme:
A kind of conveyer band discerption is reported to the police and fender guard, and it is characterized in that: device comprises an electric appliance control box, and this electric appliance control box is connected with the electric switch that the control load-transfer device stops; Electric appliance control box also is connected with at least one group of sensor, and this sensor symmetry is installed in the down either side of load-transfer device.
This sensor is an infrared ray correlation sensor, and every group of sensor is two, wherein launches infrared ray for one, and another is accepted this infrared signal.
Described sensor has 5 meters, the place ahead that are installed in the hopper of load-transfer device at least.
The utility model compared with prior art, its beneficial effect is as follows:
1, because the infrared pickoff that is installed in load-transfer device below when having molecule to leak down, just can detect, electric appliance control box also can be found and dispose in the time of 100 microseconds simultaneously, so but the utility model at high speed is found and handling problem.
2, owing to installed manyly, and installed sensor,, prevented that fracture from enlarging so more failure-free sends alerting signal and cuts off the conveyer power supply at 5 meters of hopper of the easiest generation fracture to sensor.
3, the utility model is simple in structure, practical.

Fig. 1 is the vertical tangent plane scheme drawing of the installation of the utility model embodiment;
Fig. 2 is the mounting structure scheme drawing of the utility model embodiment;
Fig. 3 is an electrical connection diagram.
1, load-transfer device 2, infrared pickoff transmitting terminal 3, infrared pickoff receiving end 4, conveyor frame 5, hopper 6, electric appliance control box 7, electric switch 8, indicator lamp 9, alarming horn
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
See also Fig. 1, shown in Figure 2, be the vertical tangent plane scheme drawing of the installation of embodiment in the utility model; Wherein, comprise a load-transfer device 1; an one infradred sensor transmitting terminal 2 and an infradred sensor receiving end 3; this infradred sensor transmitting terminal 2 and infradred sensor receiving end 3 are installed in the both sides of load-transfer device 1 in correspondence with each other; the infrared ray that transmitting terminal sends can be received termination and be subjected to; when load-transfer device 1 is intact; load-transfer device 1 does not have material to leak down; the infrared ray that the infradred sensor transmitting terminal sends does not block and can arrive infrared ray receiving end 3 fully; when load-transfer device 1 has crackle; material on the load-transfer device 1 leaks down; the infrared ray that the infradred sensor transmitting terminal sends is blocked; cannot arrive infrared ray receiving end 3 fully; electric appliance control box 6 receives the signal of infradred sensor receiving end 3, and control apparatus switch 7 turn-offs the power supply of conveyer after treatment, thereby has played the effect of protection load-transfer device.
Infradred sensor transmit and receive 5 meters that end 2 and 3 is installed in hopper, the easiest break signal that detects.
Again as shown in Figure 3, be the utility model electrical connection diagram, wherein infradred sensor 3 is connected to the input end of electric appliance control box 6, and electric switch 7 also is housed in the electric appliance control box 6, alarming horn 9, indicator lamp 8.When accepting the mal signal, can send alarm sound, indicator lamp 8 also can bright lamp simultaneously.
The above, it only is the heat abstractor preferred embodiment of the utility model electric elements, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
