Abstract
The utility model discloses an emergency stop protective device of conveying equipment. Infrared sensors are arranged above the conveying equipment and connected with a control switch of the conveying equipment. After installation of the emergency stop protective device, when a worker is dragged by a belt conveyor to move forwards and passes a first infrared sensor, a 10m infrared ray emitted from the worker can be sensed, consequently electric signals are sent to the belt conveyor, a belt conveyor control switch is switched off, a motor of the belt conveyor stops working, the belt conveyor stops operating, and therefore the worker who falls into the belt conveyor accidentally can be protected. When the first infrared sensor misses sensing and does not actuate operation, a second infrared sensor can continue sensing whether a human body enters the belt conveyor and send out the electric signals to control a motor of a crusher to be switched off through a crusher control switch, and therefore the previous error can be made up.
Description
Technical field
The utility model relates to material transport system, is specifically related to a kind of urgency in danger when transmitting material by belt conveyer and stops fender guard.
Background technology
In the existing belt-conveying machine scraper transport systems; the disintegrating apparatus such as crusher often are equipped with; such as mine scraping transporter/belt transportation system; after the material that belt conveyer transports is pulverized through crusher; transport again or the mineral products screening; belt conveyer or scrapper conveyor both sides all are provided with guard rail; but in actual repair apparatus or working process; the staff still can meet accident and fall into scrapper conveyor or belt conveyer is involved in crusher; cause the phenomenon of staff's loss of life; some belt conveyer is provided with anxious the stopping of backguy and protects; but this fender guard artificially Drawing switch just can impel equipment downtime; when the accident personnel are subjected to condition restriction can not Drawing switch or in time during Drawing switch, this fender guard does not just have answers role.
The utility model content
For solving can not the get into danger problem of auto-stop of belt conveyer in the prior art or scrapper conveyor one class automatic transporting system, the utility model provides that a kind of the urgency of auto-stop is stopped fender guard by the caloradiance of judging material on belt conveyer or the scrapper conveyor.Concrete scheme is as follows: a kind of urgency of transmission apparatus is stopped fender guard, it is characterized in that, the top of described transmission apparatus is equipped with the infrared pickoff of human body, and infrared pickoff is connected with the master cock of transmission apparatus.
The operation of control belt conveyer: described transmission apparatus comprises the belt conveyer that transports material, described infrared pickoff is the first infrared pickoff, the first infrared pickoff is connected with the belt conveyer master cock, and the belt conveyer master cock is connected with the belt conveyer motor.
For improving safety, avoid error: an end of described belt conveyer is provided with the crusher of comminuting matter, between described the first infrared pickoff and the crusher the second infrared pickoff is installed, described the second infrared pickoff is connected with the crusher master cock, and the crusher master cock is connected with motor of crusher.
Be human body: described the first infrared pickoff and the second infrared pickoff are for experiencing the ultrared infrared detector of human-body emitting.
Do not belong to the object that belt conveyer transports for detecting: described the first infrared pickoff and the second infrared pickoff comprise the transmitting terminal that is arranged on belt conveyer one side, be arranged on the belt conveyer opposite side receiving end corresponding with transmitting terminal, wherein receiving end is connected with belt conveyer master cock or crusher master cock respectively.
After the utility model device is installed; when there being the staff to be pulled when travelling forward by belt feeder; through the first infrared detector the time; the 10 μ m infrared rays that the staff launches with it can be induced; thereby send electric signal to belt feeder; the belt control switch disconnects the work of belt conveyer motor, it is shut down, thereby protected the staff who accidentally falls into.If the first infrared detector induction error, not action, whether then the second infrared detector can continue induction has human body to enter, thereby sends electric signal by the dynamo-electric tester in power-down state of crusher master cock controlled fragmentation, saves the error of front.
Description of drawings
Fig. 1 scheme of installation of the present utility model.
Attached number in the figure explanation: 1-belt conveyer, 2-the first infrared pickoff, 3-belt conveyer master cock, 4-the second infrared pickoff, 5-crusher master cock, 6-crusher, 7-motor of crusher, 8-belt conveyer motor.
The specific embodiment
As shown in Figure 1; urgency of the present utility model is stopped fender guard; the infrared pickoff that is used for detecting object that comprises the side that is installed in transmission apparatus; infrared pickoff is connected with the master cock of transmission apparatus; when infrared pickoff detects human body, can send electric signal to the master cock of transmission apparatus, master cock is received the motor rotation that can in time close current device behind the electric signal; transmission apparatus is quit work, from reaching together the staff that protection falls into accidentally.
The transmission apparatus that the utility model relates to is belt conveyer or the slat conveyer that transports material, it is the first infrared pickoff 2 and the second infrared pickoff 4 that infrared pickoff is divided into by the installation site, the first infrared pickoff 2 is arranged on a side of belt conveyer 1 according to operating range and is connected with belt conveyer master cock 3, and belt conveyer master cock 3 is connected with belt conveyer motor 8.
Because the end of belt conveyer 1 usually is the crusher 6 of broken material, it also is the root that causes the accident, for avoiding at the first infrared pickoff 2 et out of orders at belt conveyer 1 place or unidentified situation occurring, the utility model is installed the second infrared pickoff 4 in the side near crusher 6, the second infrared pickoff is connected with crusher master cock 5, and crusher master cock 5 is connected with motor of crusher 7.If the first infrared pickoff 2 goes wrong, can directly close down crusher 6 when then the second infrared pickoff 4 detects human body, play the effect of double-layer safety, as much as possible avoid injury to personnel.
Infrared pickoff of the present utility model can also be the ultrared infrared detector that can experience human-body emitting.Infrared detector can detect the infrared ray about 10 μ m of human body institute puberty, when with the human body of body temperature through out-of-date, the infrared induction source of infrared detector can change and conduct charges when receiving this infrared ray, thereby received by the control switch, and then go to stop the operation of motor.
Infrared pickoff of the present utility model can also adopt the ultrared mode of emission, infrared pickoff comprises transmitting terminal and receiving end, the transmitting terminal of infrared pickoff is arranged on a side of belt conveyer or crusher, again receiving end is arranged on the opposite side of belt conveyer or crusher, the position of transmitting terminal and receiving end setting is higher than the height of usual material filling, when having the object that is higher than material to block the infrared ray of transmitting terminal emission, receiving end can be because can not receive signal to the master cock transmitted signal of transmission apparatus, thereby master cock is closed the power supply of transmission apparatus, and the dangerous situation that may occur is prevented.
Control circuit of the present utility model can also support the use with the comprehensive protector of band conveyor is integrated; be about to increase in the existing comprehensive protective device for belt machine an infrared urgency and stop integration module, can realize the Intelligent improvement of existing comprehensive protective device for belt machine.
